Cytokine-induced killer (CIK) cells were isolated and proliferation from human peripheral blood and cultured in appropriate growth medium. The biological characteristics of CIK cells were further determined by the characterization of surface markers by flow cytometry. CIK cells inhibited the proliferation of human lung adenocarcinoma NCL-H157 cells. Vascular endothelial growth factor (VEGF) expression was down-regulated in CIK cells co-cultured with NCL-H157 cells by western blotting analysis. Furthermore, in comparison with cells untreated by CIK, the NCL-H157 had a lower proliferation capacity. We proposed that the pharmacological mechanisms of NCL-H157 promoted by CIK can be estimated possibly with different biological significance that can be ascribed to down-regulated VEGF expression in vitro. The results suggest that the VEGF pathway guides developmental inhibiting of NCL-H157, and we speculate that the function of VEGF pathways is to guide NCL-H157 to inhibition by abundant CIK.

Urolithiasis is a well-known disease. Stones can form in all parts of the urinary tract. Diagnosis and treatment usually do not create clinical problems. However from time to time in daily practice doctors are confronted with casuistic cases. Here, we report a 54-year-old man with a large stone localized to the urethra. Because of the size of the stone, confirmed on radiography, and the presence of a cutaneous fistula, open surgery was performed. Due to urethral stricture, the patient required a second stage of reconstructive surgery. This case emphasizes that unusual presentation of urolithiasis may occur, and different surgical approaches as well as other surgical manipulations in such cases must be considered.

Brain metastasis (BM) has been universally recognized as a poor prognostic factor in non-small cell lung cancer (NSCLC). Epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have shown efficacy in treating BM with an EGFR mutation. This paper reports a case of BM patient with EGFR-mutated NSCLC. According to the findings, a complete remission (CR) of the BM was achieved by icotinib treatment without conducting a radiotherapy, which was followed by a resection of the primary lung cancer lesion and lymph nodes. After one-year follow-up, the disease progressed to liver metastasis and liver lesion biopsy showed a T790M mutation. The patient responded well to the combination treatment of AZD9291 and icotinib after the failure of transcatheter arterial chemoembolization (TACE). This case report suggests that icotinib has a sustainable anticancer response to BM and the combination with icotinib and AZD9291 is effective for liver metastasis with T790M.

Introduction In Parkinson’s disease (PD), a resting tremor of the thumb may affect the flexor pollicis longus (FPL) and influence hand functions. We investigated the relationship between FPL tendon thickness and hand function in PD patients and compared these characteristics with those in healthy controls. Methods The hand grip and pinch strengths were measured. The participants completed the Duruöz hand index, the Sollerman’s hand function test, and the Nine Hole Peg Test. The thickness of the FPL tendon was measured using ultrasonography Results The FPL tendon was thicker in PD patients but was not associated with tremor severity. In PD patients, despite functional performance of the hands are impaired and grip strength is decreased, pinch strengths are preserved. FPL thickness was not correlated with grip and pinch strengths. Conclusion The thicker FPL tendon may be associated with greater pinch and grip strengths and manual dexterity in healthy individuals. The presence of tremor is associated with a thicker FPL tendon.

Objective To assess circulating tumor cells in cerebrospinal fluid as a diagnostic approach to identify meningeal metastasis in patients with non-small cell lung cancer by using tumor marker immunostaining–fluorescence in situ hybridization (TM-iFISH). Methods In 5 non-small cell lung cancer patients who were confirmed to have developed meningeal metastasis by cerebrospinal fluid cytology, 20 ml of cerebrospinal fluid was obtained through lumbar puncture, from which 7.5 ml was utilized for TM-iFISH to identify and quantitate circulating tumor cells, 10ml for cerebrospinal fluid cytology, and 2.5ml for detection of cerebrospinal fluid tumor markers. Results TM-iFISH examination identified 18 to 1,823 circulating tumor cells per 7.5ml cerebrospinal fluid. In contrast, cytology assessment revealed tumor cells in only 2 cases. The expression levels of cerebrospinal fluid tumor markers were all increased in all 5 patients when compared with their respective serum levels. Contrast-enhanced MRI scans demonstrated presence of meningeal metastasis in all 5 cases. Conclusion TM-iFISH may become a novel cerebrospinal fluid-based diagnostic strategy to identify circulating tumor cells and meningeal metastasis as compared to traditional diagnostic approaches, although its superior sensitivity and specificity needs to be confirmed through additional studies with a larger sample size.

Background The aim of this study was to evaluate the neuroprotective effect of surgery combined with traditional Chinese medicine(TCM)in the treatment of glaucoma by meta-analysis based on clinical controlled trial. Methods All the prospective randomized controlled trialsof surgery combined with TCM in the treatment of glaucoma were searched in the databases of Medline (1960-2015.1), CENTRAL (the Cochrane central register of controlled trials 1989-2015.1, EMBASE (1980∼2015.1) and CNKI (1979-2015.1). Two reviewers independently assessed the quality of the included studies, extracted the relevant data and performed a cross-check. The pooled relative risk (RR) or standard mean difference (SMD) of surgery combined with TCM versus western medicine or surgery alone were calculated as the effect size by meta-analysis method. All the data was analyzed by stata11.0 software (http://www.stata.com; Stata Corporation, College Station, TX). Results Finally, eleven clinical controlledtrails with 843 subjects were included in this meta-analysis. The pooled results indicated that the surgery combined with TCM treatment procedure can significant improve the vision recovery rate compared to control group (RR=1.22, 95% CI:1.06∼1.40, P=0.005); And after treatment, the visual field in combined group was significantly improved compared to control group (SMD=0.26∼95% CI:0.09∼0.43, P=0.003). Conclusion Surgery combined with TCM can improve the vision recovery rate and the visual fieldin the treatment of glaucoma compared to surgery or western medicine alone.

Objectives Increasing evidence showed that microRNAs (miRNAs) were implicated in the chemical resistance of human cancers. We intended to investigate the role of miR-218 in cisplatin sensitivity of esophageal cancer cells. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was carried out to analyze miR-218 expression in human esophageal cancer cell line Eca9706 and a cisplatin-resistant subline (ECa9706-CisR cells). The effects of miR-218 transfection on ECa9706 and ECa9706-CisR cell viability, including cell viability and apoptosis rate were confirmed using MTT assay, or flow cytometry, respectively. qRT-PCR was used to validate survivin as a direct target gene of miR-218 in our system. Results We found that miR-218 was significantly decreased in ECa9706-CisR cells compared with parent Eca9706 cells. Overexpression of miR-218 by mimics transfection would enhance cisplatin sensitivity evaluated by cell viability inhibition and apoptosis promotion. We validated here survivin as a direct target of miR-218 in ECa9706 cells, which might contribute to the chemoresistance of esophageal cancer cells to cisplatin. Conclusions In summary, our data suggest that miR-218 might represent as a promising sensitizer of cisplatin therapy in clinical esophageal cancer patients.

Objectives Although the Hox transcript antisense intergenic RNA (HOTAIR), a vital long non-coding RNA, is known to participate in the development and progression of a wide range of carcinomas, there are still no published reports regarding its expression in adenocarcinoma of esophagogastric junction (AEJ). The aims of this study were to investigate the expression of HOTAIR, and to analyze the association of its expression with PI3K/Akt pathway activation in clinical AEJ patients. Methods Nine normal epithelial tissues and 41 samples of AEJ were studied comparably. The expression of HOTAIR was detected by real-time PCR according to the different tumor grades in these AEJ tissues. Western blot was performed to reveal the Ser473-phosphorylated Akt and total Akt levels. Results: HOTAIR was found to be up-regulated in higher grades of AEJ tissues compared to low grades and/or noncancerous tissues. pAkt expression was also found to be up-regulated in tissues of higher tumor stages. We found that the overexpression of HOTAIR finely correlated with elevated Ser473-phosphorylated Akt levels. Conclusion: Upregulated HOTAIR was associated with abnormal activated PI3K/Akt pathway, which might serve as a promising therapeutic strategy for AEJ treatment.

Background Research studies conducted in recent years have confirmed that in the absence of medical illnesses, depressive disorders are associated with upregulation of many inflammatory cytokines such as tumor necrosis factor-aplha (TNF-α), interleukin-1 and 6 (IL-1,IL-6). The main objective of the study was to examine whether recurrent depressive disorders (rDD) are accompanied by more profound inflammatory disturbances than the first episode of depression (ED-I). The analysis included the expression of mRNA and protein levels of three interleukins namely. IL-1, IL-6 and IL-10. Methods The study was carried out in a cohort of 130 patients: ED-I group – 44 patients, rDD group – 86 patients respectively. Results Our results suggest that there was no significant statistical difference between the analyzed groups as regards the intensity of the depressive disorders. Furthermore, No differences in the expression of IL-1, IL-6 and IL-10 genes on the level of both mRNA and protein were observed among the groups. Additionally, there was no significant interrelation been documented between the number of depression episodes experienced v/s the expression of selected genes. Conclusions There is no significant difference in IL-1, IL-6 and IL-10 expression between patients with recurrent depressive disorders and those suffering from the first episode of depression. 2. There seems to be no difference in acute first episode depression vs. acute episode of depression in patients with a recurrent disorder. Further larger trials are needed.

Primary pulmonary diffuse large B-cell lymphoma (PPDLBCL) is extremely rare. Its clinical symptoms and signs are nonspe cific, and imaging features also have not yet been well-defined. Further description is important for the diagnosis and treatment of PPDLBCL. Herein, we reported a case of a patient who suffered from bilateral chest pain and dyspnea. Computed tomography (CT) of chest demonstrated bilateral lung mass, consolidations and reverse halo sign, while consolidations and reverse halo sign are uncommon according to previous reports. Tissue samples were taken by CT guided needle biopsy. The histological samples showed PPDLBCL. This case was special in view of positive expression of CD5. After the case was treated by cyclophosphamide pirarubicin vindesine dexamethasone (CHOP) chemotherapy for six courses, her clinical symptoms were partially alleviated, while CT showed progression disease. This case report highlights different imaging features and characteristics of molecular biology, and reviews study progress of PPDLBCL.

Background To investigate the magnetic diffusion weighted imaging (DWI) sequence and Spondyloarthritis Research Consortium of Canada (SPARCC) scoring in assessing curative effect of combined treatment of Chinese and Western medicine for early ankylosing spondylitis (AS). Methods 48 cases diagnosed as early AS and treated with Chinese and Western medicine were included in the study. Magnetic routine and DWI sequence scanning image were performed to obtain the mean apparent diffusion coefficient (ADC) value of sub-articular surface bone marrow. Combined with SPARCC scoring, statistical analysis was conducted to compare the difference with the information obtained in the previous study. Results The mean ADC value in the sub-articular surface bone marrow of patients after clinical treatment: (4.34±0.55)×10-4mm2/s in ilium and (3.96±0.23)×10-4mm2/s in sacrum, which were both significantly lower than that before treatment (p< 0.05). There was highly positive correlation between mean ADC value and SPARCC scoring (P<0.05). The regression relationship could be demonstrated as Y=-64.420+21.262X(Y: SPARCC scoring value; X: mean ADC value). Conclusions Magnetic DWI and SPARCC scoring could be applied in accessing AS inflammation activity changes and in reflect of curative effect of early AS patients as well as in providing reliable radiologist evidence for clinical therapeutic efficacy.

Non-small cell lung cancer (NSCLC) is the leading cause of cancer related deaths worldwide. But no one type of serum biomarker was found to be highly sensitive and specific for detection of lung cancer at present. So, the aim of this study was to evaluate a diagnostic value of serum carcinoembryonic antigen (CEA), neuron specific enolase (NSE) and matrix metallo-proteinase (MMP-9) for non-small cell lung cancer. Thirty-six cases with pathology confirmed non-small cell lung cancer and thirty-two of subjects with benign lung disease were reviewed in our hospital and included in this retrospective study. The serum level of CEA, NSE and MMP-9 were tested and compared between the non-small cell lung cancer patients and benign lung disease. The diagnosis sensitivity, specificity and area under the receiver-operating characteristic (ROC) curve (AUC) for serum CEA, NSE and MMP-9 were calculated with STATA10.0 software. The serum CEA, NSE and MMP-9 were 32.0±16.7 ng/mL, 51.6±68.3 ng/mL, 30.6 ±15.7 μg/L for the NSCLC patients and 15.1±10.9 ng/mL, 4.9±3.1 ng/mL, 9.3±5.9 μg/L for the benign lung disease patients with statistical difference (Pall<0.05); The diagnosis sensitivity, specificity and AUC were 80.0%, 72.2%, 0.84 for the serum CEA; 71.0%, 83.3% and 0.80 for NSE and 87.1%, 80.56%, 0.89 for MMP-9, respectively. The serum CEA, NSE and MMP-9 were generally elevated in patients with non-small cell lung cancer and could be used as potential bio-markers for non-small cell lung cancer diagnosis.

Tuberculosis is still the most frequent granulomatous laryngeal disease. Absence of pathognomonic symptoms and change in clinical pattern frequently leads to misdiagnosis and delayed treatment. Hoarseness is the commonest symptom of laryngeal tuberculosis and constitutional symptoms are usually rare. However dysphonia can be caused by many other more common conditions. Hoarseness can be a symptom of organic (nodules and polyps of vocal folds, tumors, vocal fold paresis) or functional (functional dysphonia, laryngeal conversion disorder, paradoxical vocal folds motion) conditions. Rarely systemic diseases as amyloidosis, sarcoidosis, Wegener’s granulomatosis or tuberculosis can cause vocal dysfunction too. That is why laryngeal tuberculosis is often forgotten in case of persistent hoarseness. In this article, we present a case of a young previously healthy woman, complaining of persistent hoarseness with no other leading symptoms. Though endoscopic image suggested a malignancy, histology showed granulomatous lesion. Detailed examination revealed laryngeal and pulmonary tuberculosis resistant to rifampicin. Conclusion: Dysphonia can be the only one symptom of laryngeal tuberculosis. The disease should be taken into consideration when a patient complains of persistent hoarseness in order to avoid delays in treatment and spread of infection.

Individualized therapies targeting epidermal growth factor receptor (EGFR) mutations show promises for the treatment of non small-cell lung carcinoma (NSCLC). However, disease progression almost invariably occurs 1 year after tyrosine kinase inhibitor (TKI) treatment. The most prominent mechanism of acquired resistance involves the secondary EGFR mutation, namely EGFR T790M, which accounts for 50%–60% of resistant tumors. A large amount of studies have focused on the development of effective strategies to treat TKI-resistant EGFR T790M mutation in lung tumors. Novel generations of EGFR inhibitors are producing encouraging results in patients with acquired resistance against EGFR T790M mutation. This review will summarize the novel inhibitors, which might overcome resistance against EGFR T790M mutation.

Objective The inhibitory role of microRNA-29a (miR-29a) has been assessed in breast cancer cells. Herein, we analyze the underlying mechanisms of its role in cell cycle progression in breast cancer cells. Methods We applied real-time polymerase chain reaction (PCR) to detect the expression of miR-29 in breast cancer cell lines. Then one of the cell lines, MDA-MB-453, was transfected with mimics of miR-29a. The cell cycle was analyzed by fluorescence-activated cell sorting after staining the cells with propidium iodide. Real-time PCR, luciferase assay and western blot were used together to verify the regulation of the predicted target, cell division cycle 42 (CDC42) by miR-29a. Results MiR-29s were decreased in our selected mammary cell lines, among which miR-29a was the dominant isoform. Overexpression of miR-29a caused cell cycle arrest at the G0/G1 phase. We further found that miR-29a could target the expression of CDC42, which is a small GTPase associated with cell cycle progression. Conclusion We suggest that miR-29a exerts its tumor suppressor role in breast cancer cells partially by arresting the cell cycle through negative regulation of CDC42.

The TGF-β/SMAD signaling pathway is found to play pivotal roles in cell growth, differentiation and tumorigenesis. Its target genes are closely related to the biological behaviors of some malignancies. The aim of this study was to analyze the expression of the target genes of this pathway, including growth-related c-myc, p21, p15, and metastasis-related Snail, ZEB1 and Twist1 in the adenocarcinomas of esophagogastric junction (AEJ) tissues. Clinical esophagogastric junction tissues from 25 cases of AEJ patients and 10 cases of non-tumorous tissues from the same site were collected. Quantitative real-time poly chain reactions were carried out to analyze the expression of the above referred target genes of TGF-β/SMAD pathway. A notable up-regulation in the mRNA expression of p15, Snail, ZEB1, down-regulation of c-myc, was found whereas there were no significant change of p21 and Twist1. The findings suggests that the TGF-β/SMAD pathway might be abnormally activated in AEJ since most of the target genes of this pathway exhibited altered expression at mRNA level.

The side effects of radioactive iodine (131-I) treatment of differentiated thyroid cancer (DTC) patients include reduction of peripheral blood cell counts. The aim of this study was to analyze some potential changes in blood cell counts of DTC patients after 131-I therapy, especially CD3-positive, CD19-positive, and CD56-positive peripheral blood lymphocytes (PBL), as well as the possible role of apoptosis in selected lymphocyte populations. The study group included 24 thyroid cancer patients and 24 control subjects. Peripheral blood samples from patients and controls were analyzed using 5-color flow cytometry. Apoptotic cells were detected using an Annexin V-FITC/7-AAD kit. There was a statistically significant decrease of all blood cells after the 131-I therapy. The CD19+ B lymphocyte population was the most affected (5.82 ± 3.21% before therapy vs. 3.93 ± 2.60% after therapy, p = 0.008). This decrease was correlated with the degree of apoptosis of peripheral blood lymphocytes (Spearman’s r = 0.563, p =0.013). We concluded that 131-I therapy of DTC patients led to a decrease of all peripheral blood cells, especially CD19+ B lymphocytes. This directly correlated with apoptosis of PBLs, indicating that radiation damage to B cells leads to subsequent elimination by apoptosis.

Objective To discuss the application of ARMS method to detect EGFR gene mutation in cerebrospinal fluid of lung adenocarcinoma patients with meningeal metastasis. Methods 5 cases of lung adenocarcinoma were identified with meningeal metastasis that were cleared EGFR gene mutation by gene sequencing method. From each patient 5ml cerebrospinal fluid was obtained by lumbar puncture. ARMS method was used to detect EGFR mutations in cerebrospinal fluid. Results 5 samples of cerebrospinal fluid were successfully detected by ARMS method, 3 samples found that EGFR gene mutations, the mutations in line with direct sequencing method. Conclusion ARMS method can be used to detect EGFR gene mutations of cerebrospinal fluid samples in lung adenocarcinoma with meningeal metastasis. But cerebrospinal fluid specimens from histological specimens, blood samples need to be confirmed by further comparative study whether there is advantage.

Primary immune thrombocytopenia (ITP) is a complex autoimmune disorder in which the patient’s immune system reacts with platelet autoantigens resulting in immune-mediated platelet destruction and/or suppression of platelet production. Corticosteroids can induce sustained remission rates in 50% to 75% of patients with active ITP. For these patients who are unresponsive to glucocorticoids, or relapsed after an initial response, multiple second-line treatment modalities can be chosen. However, how to make an optimal therapeutic strategy for a specific patient still remains a major challenge. As the pathogenetic heterogeneity of the ITP is increasingly identified, pathogenesis-oriented approach might offer an opportunity to improve the outcome of corticosteroid-resistant or relapsed ITP.

The association between GSTP1 A>G polymorphism and chemosensitivity of osteosarcoma is controversial according to previously published studies. We conducted this meta-analysis to further investigate the role of GSTP1 A>G genetic variation in response to chemotherapy resistance in patients with osteosarcoma. Using the electronic databases of Pubmed, Wanfang and CNIK were searched to find the studies related to the GSTP1 A>G polymorphism and chemosensitivity of osteosarcoma. The genotype of AA, AG and GG were extracted from the chemotherapy sensitivity and chemotherapy resistance group. The association between GSTP1 A>G polymorphism and chemosensitivity was calculated by STATA11.0 software. The correlation between GSTP1 A>G polymorphism and chemotherapy response was assessed by odds ratio (OR) and its 95% confidence interval (95%CI). Four studies with 681 cases were finally included in this meta-analysis. The pooled data indicated that there was no significant association between GSTP1 A>G polymorphism and chemosensitivity in patients with osteosarcoma [Homozygous genetic model (GG vs AA): OR=0.53, 95%CI: 0.25-1.12, P=0.10; recessive genetic model (GG vs GA+AA): OR=0.61, 95%CI:0.34-1.11,P=0.11; and dominant genetic model (GG+AG vs AA): OR=0.67, 95%CI:0.42-1.07,P=0.10]. No correlation between GSTP1 A>G polymorphism and chemosensitivity was found according to this present meta-analysis. However, the small number of cases in each included study and significant statistical heterogeneity among the trials means the conclusion should be regarded as conservative.

Several studies have investigated the correlation between adiponectin gene rs22411766 T>G polymorphism and ischemic stroke risk. However, the results were not conclusive with each other. Therefore, to overcome this obstacle, we performed this meta-analysis to further explicate the adiponectin gene rs22411766 T>G polymorphism and ischemic stroke susceptibility. Case-control or cohort studies focused on adiponectin gene rs22411766 T>G polymorphism and ischemic stroke risk were electronic searched in the databases of Medline, Pubmed, Cochrane library, Excerpta Medica database(EMBASE) and China National Knowledge Infrastructure (CNKI). All the potentially relevant studies were included in this meta-analysis. The association between adiponectin gene rs22411766 T>G polymorphism and ischemic stroke was expressed by odds ratio with its confidence interval. Publication bias has been assessed by begg’s funnel plot. All the analyses have been performed by Revman 5.1 statistical software. Finally, a total of six studies with 1,345 cases and 1,421 controls were included in this meta-analysis. Our results demonstrated that there was a significant association between adiponectin gene rs22411766 T>G polymorphism and ischemic stroke risk (p<0.05). People with G single nucleotide of adiponectin gene have the increased risk of developing ischemic stroke compared to T single nucleotide.

Objective To evaluate the value of individual and combined measurement of human epididymis protein 4 (HE4) and cancer antigen 125 (CA-125) in the diagnosis of ovarian cancer. Methods A clinical case-control study was performed in which the levels of serum HE4 and CA-125 of subjects with malignant, borderline, benign ovarian tumors and healthy women were measured before surgery. An immunohistochemistry method was used to measure the expression of HE4 in different tissues. Statistical analysis was performed to determine the relationship between the level of HE4 and the pathologic type as well as the stage of the ovarian tumors. Results The level of HE4 in the serum was significantly elevated in the malignant ovarian cancer group compared with other groups. Women with benign ovarian tumors and non-neoplastic lesions, and healthy women were designated as references. When the level of HE4 in the serum was 58.66 pmol/L, the sensitivity and specificity of HE4 in diagnosing malignant ovarian tumors was 82.35% and 96.03%, respectively. The level of HE4 was negatively correlated with the differentiation extent of the tumors whereas positively correlated to the clinical staging. In the groups of malignant and borderline tumors, the levels of HE4 were higher than the other groups. The expression of HE4 was significant higher in the serous types of ovarian tumors than that of the mucous types (P<0.05). The level of HE4 in the serum and tissues were positively correlated with each other. Conclusion HE4 can be used as a novel clinical biomarker for predicting malignant ovarian tumors and its expression was closely related with the clinical pathological features of malignant ovarian tumors.

Objective Sex-determining region Y-box 7 (SOX7) is a putative tumor suppressor in various types of human cancers. In the present study, the expression and function of SOX7 was investigated in human glioblastoma (GBM) cells. Methods Real-time PCR and western blot were carried out to reveal the expression of SOX7 in GBM specimens and cultured cell lines. A short interfering RNA (siRNA) targeting SOX7 was synthesized and transfected into U87 cells. 3-(4,5-Dimethylthiazol-2-yl)- 2,5-diphenyltetrazolium bromide (MTT) assay was performed to valuate the cell proliferation ability in U87 cells. Bioinformatics analysis further predicted its regulation by microRNA-24 (miR-24). Luciferase reporter assay was performed to prove this regulation. Results SOX7 was downregulated in GBM specimens and cell lines. Inhibition of SOX7 in cultured U87 cells resulted in a slower growth rate. Mechanically, SOX7 was a target of miR-24, demonstrated by reporter assay. Conclusion SOX7 was a strong tumor suppressor regulated by miR-24 in human GBM cells.

Background To explore the effect of sevoflurane inhalation anesthesia on evoked electromyography monitoring of spinal nerve root in children associated with cerebral palsy. Methodology Children with cerebral palsy (n=40) were selected and further divided into 1MAC (minimum alveolar concentration) sevoflurane group and 2MAC sevoflurane group. Following the induction of anesthesia, Nicolet Endeavor-CR16 channel electrophysiological monitor was used to implement three times of successive electrical stimulation with interval of 5 sec at 3.50 mA. Results Our results suggested a statistical significance of amplitude retention ratio and latency in the sevoflurane inhalation time (P<0.01), with an interaction effect between the sevoflurane inhalation time and concentration for amplitude retention ratio (P<0.01), while there is no interaction effect between the sevoflurane inhalation time and concentration for latency (P>0.05). Compared to 1MAC sevoflurane group, the amplitude retention ratio of 2MAC sevoflurane group decreased remarkably (P<0.01) and the latency of 2MAC sevoflurane group extended at T3 and T4 (P<0.05 or P<0.01). Conclusions In evoked electromyography monitoring of spinal nerve root in children with cerebral palsy, with the increasing of concentration and duration of sevoflurane inhalation, evoked electromyogram retention ratio reduces gradually, latency extends and the retention ratio has more changes than the latency.

Hereditary spherocytosis (HS) and Chronic myelocytic leukemia (CML) are both life threatening hemotologic diseases. They are rarely seen to occur simultaneously in one individual patient. Here we demonstrate a case of HS associated with CML in this study. The patient is a young female, diagnosed with HS in 2005, and was given partial embolization of the splenic artery. She got significant remission after the procedure. In 2008, she was found abnormal in blood routine test, after bone marrow routine, chromosome and fusion gene tests, she was diagnosed with CML (chronic phase). She did not receive regular treatment until 3 months prior, and is currently being treated with Dasatimib. She achieved hematological remission, but had no significant improvement in chromosome and fusion gene figures. Due to her severe condition of hemolysis, a splenectomy or an allogeneic hematopoietic stem cell transplantation is considered.

Saphenous vein graft aneurysm (SVGA) is one of the chronic complications after coronary aorta bypass grafting (CABG) and may be caused by atherosclerosis-like phenomena of the vein graft, weakness around the vein valve, rupturing of the suture of the graft anastomosis, or perioperative graft injury. We describe a case of a large, growing saphenous vein graft aneurysm that was followed serially by chest radiography and computed tomography. Eighteen years after CABG, an SVGA (23 × 24 mm) was incidentally detected. The patient was asymptomatic and was followed conservatively. Four years later, coronary computed tomographic angiography showed that the giant aneurysm had grown to 52.1 by 63.8 mm and revealed a second, smaller aneurysm. Finally, the SVG was ultimately resected without bypass via off-pump surgery. Therefore, this case suggested that aggressive treatment that includes surgical intervention should be considered before the aneurysm becomes larger, even if it is asymptomatic.

Objective: To examine the expression and function of long non-coding RNA taurine up-regulated 1 ( TUG1 ) in human osteosarcoma cells. Methods: Real-time quantitive PCR was used to detect the transcription level of TUG1 in a series of osteosarcoma cell lines. Knockdown of TUG1 in U2OS cells was carried out by transient transfection of siRNAs. MTT assay was performed to access the cell growth rates. Afterwards, RNA and protein of these cells were extracted to analyze the transfection efficient as well as the expression of other molecules. Results: Compared to the normal cell line, TUG1 exhibited a significant upregulation in osteosarcoma cells. Phenotyping analysis showed the growth-promotion activity of TUG1 , since knockdown of TUG1 resulted in declined proliferation. We also found that AKT phosphorylation was impaired after TUG1 was inhibited, suggesting that the AKT pathway was involved in the regulation of TUG1 in U2OS cells. Conclusion: Our data provided evidence that TUG1 was upregulated and acted as a possible oncogene via positively regulating cell proliferation in osteosarcoma cells.

Meningioma accounts for more than 30% of all intracranial tumours. It affects mainly the elderly above the age of 60, at a female:male ratio of 3:2. The prognosis is variable: it is usually favourable with no progression in tumour grade and no recurrence in WHO grade 1 tumours. However, a minority of tumours represent atypical (grade 2) or anaplastic (grade 3) meningiomas; this heterogeneity is also reflected in histopathological appearances. Irrespective of the grade, the size of the tumour and the localisation may have severe, sometimes lethal consequences. Following neurosurgical interventions to remove the tumour, recurrence and progression in WHO grade may occur. Our knowledge on predisposing histomorphological and molecular factors of recurrence is rather limited. These can be classified as I) demographic II) environmental, III) genetic and epigenetic IV) imaging, V) neuropathological, and VI) neurosurgical. In view of the complex background of tumour recurrence, the recognition of often subtle signs of increased risk of recurrence requires close collaboration of experts from several medical specialties. This multidisciplinary approach results in better therapy and fewer complications related to tumour recurrence.

Among two tracheobronchial forms (local and diffuse) and two parenchymal forms (nodular and alveolar septal) that were reported in previous literature, localized endobronchial amyloidosis is an uncommon disease of unknown cause. Bronchial amyloid deposits can occur as focal nodules or multifocal infiltration of the submucosa. We report the case of a 47-year-old man who had complained of dyspnea and wheezing for 1 month and who had been treated for severe asthma at another hospital. Endobronchial amyloidosis was confirmed by histological examination of the bronchial biopsies.

Pulmonary Langerhans Cell Histiocytosis (PLCH) is a rare disease. From the insidious onset and nonspecific manifestations, it is difficult to diagnose PLCH. To help improve the diagnosis and therapy options of adult PLCH, we present this case report and literature review about a confusing case of PLCH. In this report, we present a 37-year-old male PLCH case that was negative for CD1a and S100 expression. Smoking cessation and use of prescribed Spiriva appeared to improve the patient’s symptoms. To the best of our knowledge, this is the first reported case of PLCH in which improved symptoms were seen with the use of Spiriva alone.The mechanism is not clear, but potentially has some relationship with dilating the airway, decreasing the mucous hypersecretion and promoting anti-inflammatory pathways. From this patient’s case, we may be able to find more cases to then find other first line therapies for PLCH patients.

Background. Chaperone activity of α-crystallin in the lens works to prevent protein aggregation and is important to maintain the lens transparency. This study evaluated the effect of hesperetin on lens chaperone activity in selenite-induced cataracts. Methodology. Thirteen-day-old rats were divided into four groups. Animals were given hesperetin (groups G2 and G4) or vehicle (G1 and G3) on Days 0, 1, and 2. Rats in G3 and G4 were administered selenite subcutaneously 4 hours after the first hesperetin injection. On Days 2, 4, and 6, cataract grades were evaluated using slit-lamp biomicroscopy. The amount of a-crystallin and chaperone activity in water-soluble fraction were measured after animals sacrificed. Results. G3 on day 4 had developed significant cataract, as an average cataract grading of 4.6 ± 0.2. In contrast, G4 had less severe central opacities and lower stage cataracts than G3, as an average cataract grading of 2.4 ± 0.4. The a-crystallin levels in G3 lenses were lower than in G1, but the same as G4. Additionally, chaperone activity was weaker in G3 lenses than G1, but the same as in G4. Conclusions. Our results suggest that hesperetin can prevent the decreasing lens chaperone activity and a-crystallin water solubility by administered of selenite.

Background Early detection of high-risk population for osteoporosis is the key to preventing this disease. Methodology: In this cross-sectional study a continuous sample of 270 women and 89 men (age: 20–90 years) was divided into four groups by age (≤ 55 or > 55 years) and sex. Participants completed the IOF test. Low-, medium-, and high-risk grades were defined by an OSTA index of greater than -1, -1 to -4, and less than -4, respectively. Results: Most participants were categorized in the low-risk group (240 people, 66.9%), followed by the medium-risk (102 people, 28.4%) and high-risk groups (17 people, 4.7%). Compared to women, men in both age groups had significantly higher OSTA index and greater numbers of positive answers on the IOF test. 64.3% individuals were susceptible to osteoporosis risk (≥1 positive answers on the IOF test). Multiple regression analysis demonstrated that family history of fragility fracture (OR: 0.503, 95% CI: 0.26–0.97), height loss exceeding 3 cm (OR: 2.51, 95% CI: 1.55–4.05), and earlier menopause (OR: 0.434, 95% CI: 0.19–0.97) were associated with higher risk grades. Conclusions: Combined use of the OSTA and IOF test is a simple and effective method for assessing the risk of osteoporosis.

Objective The aim of this study was to investigate the correlation of von Hippel-Lindau tumor suppressor (VHL) mRNA expression and jade family PHD finger 1 (Jade-1) gene expression in patients with renal cell carcinoma (RCC). Another aim of this study was to analyze the relationship of these two genes with clinicalpathological features of the RCC patients. Methods: A total of 75 RCC patients who received surgically therapy in our hospital were included. All patients had complete pathological data. The expression of VHL/Jade-1 was determined by real-time polymerase chain reaction (RT-PCR). Results: VHL and Jade-1 were both obviously downregulated in RCC tissues than that of the matched normal tissues, and both negatively correlated with tumor size as well as tumor grade. And we found a fine association of VHL gene expression with Jade-1. Conclusion: VHL/Jade-1 exhibited significantly decreased expression in RCC tissues and was closely related to the clinical prognosis of patients. The finding of VHL expression positively correlated with Jade-1 expression shed light and provided crucial evidence on the connection of VHL protein with Wnt/b-catenin pathway.

Objective The optimal diagnostics and treatment of acute appendicitis continues to be a challenge. A false positive diagnosis of appendicitis may lead to an unnecessary operation, which has been appropriately termed negative appendectomy. The aim of our study was to identify the effectiveness of preoperative investigations in preventing negative appendectomy. Methods A retrospective study was performed on adult patients who underwent operation for suspected acute appendicitis from 2008 to 2013 at Vilnius University Hospital Santariskiu Klinikos. Patients were divided into two groups: group A underwent an operation, where appendix was found to be normal (non-inflamed); group B underwent an appendectomy for inflamed appendix. Groups were compared for preoperative data, investigations, treatment results and pathology findings. Results 554 patients were included in the study. Preoperative laboratory tests results of hemoglobin, hematocrit concentrations and white blood cell count were significantly higher in group B (p<0.001). Ultrasonography was performed for 78 % of patients in group A and 74 % in group B and did not provide any statistically significant results. Comparing Alvarado score results, there were more patients with Alvarado score less than 7 in group A than in group B. In our large series we could find only four independent risk factors, and they could only account for 24 % of cases. Conclusions In summary, acute appendicitis is still often misdiagnosed and the ratio of negative appendectomies remains rather high. Additional investigations such as observation and computed tomography should be used to prevent this.

Platelet rich plasma (PRP) represents a relatively new approach in regenerative medicine. It is obtained from patient’s own blood and contains different growth factors and other biomolecules necessary for wound healing. Since there are various protocols for PRP preparing, it usually results with PRP generation with different amounts of bioactive substances, which finally may modulate the intensity of wound healing. The reference data about potential effect of some PRP compounds on wound healing, in different tissues, are still controversial. This review summarizes recently known facts about physiological role of certain PRP components and guidance for further research. Also, this review discusses different procedure for PRP generation and potential effect of leukocytes on wound healing.

Objective The aim of this meta-analysis was to undertake a meta-analysis to evaluate the correlation between cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) gene rs221775 A>G single nucleotide polymorphism and the susceptibility of multiple sclerosis (MS) susceptibility. Method Published manuscripts about CTLA-4 gene rs221775A>G single nucleotide polymorphism and multiple sclerosis susceptibility were searched in the computerized bibliographic searches of Pubmed Embase and China National Knowledge Infrastructure (CNKI). Potential studies were screened and data for 5025 MS patients and 4706 controls from 20 publications were included. The association between CTLA-4 gene rs221775A>G single nucleotide polymorphism and multiple sclerosis susceptibility were demonstrated by odds ratio (OR) and 95% confidence interval (95%CI). Results The pooled results showed no significant association between CTLA-4 gene rs221775A>G single nucleotide polymorphism and multiple sclerosis susceptibility for dominant genetic model [OR=1.02, 95%CI:0.90~1.05, (P=0.80)], homozygous genetic model [OR=0.85,95%CI:0.71 ~1.03,(P=0.10)] and recessive genetic model [OR=0.99,95% CI:0.89~1.10,(P=0.90)]. Conclusion With current evidence, CTLA-4 gene rs221775A>G single nucleotide polymorphism had no association with the susceptibility of multiple sclerosis

Interventional radiology is a rapidly growing discipline with an expanding variety of indications and techniques in pediatric and adult patients. Accordingly, the number of procedures during which monitoring either under sedation or under general anesthesia is needed is increasing. In order to ensure high-quality care as well as patient comfort and safety, implementation of anes-thesiology practice guidelines in line with institutional radiology practice guidelines is paramount [1]. However, practice guidelines are no substitute for lack of communi-cation between specialties. Interdisciplinary indications within neurosciences call for efficient co-operation among radiology, neurology, neurosurgery, vascular surgery, anesthesiology and intensive care. Anesthesia team and intensive care personnel should be informed early and be involved in coordinated planning so that optimal results can be achieved under minimized risks and pre-arranged complication management.

Objective To evaluate the expression and correlations of liver X receptor alpha (LXRa) and its target gene sterol regulatory element-binding protein-1c (SREBP-1c) in placentas of preeclampsia (PE) and their significance in PE. Methods Pregnancies were divided into two groups, 60 cases (29 cases of mild and 31 cases of severe) of PE group and 56 cases of normal group. The level of mRNA and protein of LXRa and SREBP-1c were analyzed by reverse transcription-polymerase chain reaction (RTPCR) and immunohistochemistry (IHC) in the placentas. Results RT-PCR and IHC results showed that the mRNA and protein expression of both LXRa and SREBP-1c increased gradually with the extent of PE among normal pregnancy, mild PE and severe PE groups, and the differences were of statistically significance (P<0.01 or P<0.05). There were positive correlations between the expression of LXRa mRNA and SREBP-1c mRNA, also between LXRa mRNA and LXRa protein (r=0.521, P<0.01; r=0.422, P<0.01). The expression of SREBP-1c mRNA positively correlated with its protein level (r=0.598, P<0.01). There were positive correlations between the expression of LXRa protein and SREBP-1c protein (r=0.612, P<0.01). Conclusion The expression of LXRa is elevated significantly in placentas of PE patients, and might contribute for promoting the transcription and translation of its target gene SREBP1-c, which is related to the occurrence and development of PE.

This study attempts to investigate the impact that the sensory integration training has on the recovery of balance among patients with stroke by examining the muscle activity and limit of stability (LOS). A total of 28 subjects participated. The subjects were randomly allocated by the computer program to one of two groups: control (CON) group (n=15), sensory integration training (SIT) group (n=13). The research subjects received intervention five days a week for a total of four weeks. The CON group additionally received 30-minute general balance training, while the SIT group additionally received 30-minute sensory integration training. In the muscle activity, the improvement of Erector spinae (ES) and Gluteus medius (GM) was more significant in the SIT group than in the CON group. In the LOS, the improvement of affected side and forward side was significantly higher in the SIT group compared to the CON group. Sensory integration training can improve balance ability of patients with stroke by increasing muscle activity of stance limb muscles such as GM and trunk extensor such as ES along with enhancement of the limit of stability.

Psoriasis is a chronic, autoimmune, and complex genetic disorder that affects 23% of the European population. The symptoms of Psoriatic skin are inflammation, raised and scaly lesions. microRNA, which is short, nonprotein-coding, regulatory RNAs, plays critical roles in psoriasis. microRNA participates in nearly all biological processes, such as cell differentiation, development and metabolism. Recent researches reveal that multitudinous novel microRNAs have been identified in skin. Some of these substantial novel microRNAs play as a class of posttranscriptional gene regulator in skin disease, such as psoriasis. In order to insight into microRNAs biological functions and verify microRNAs biomarker, we review diverse references about characterization, profiling and subtype of microRNAs. Here we will share our opinions about how and which microRNAs are as regulatory in psoriasis.

The objective of this study is to describe the clinical and epidemiological characteristics of patients hospitalized in Lithuania who are infected with influenza A(H1N1)pdm09 and to compare pandemic A(H1N1) pdm09 infection with postpandemic. In total, 146 subjects hospitalized with influenza A(H1N1) pdm09 were identified from 2009–2011. There were 53 during the initial pandemic wave in the summer of 2009, 69 during the peak pandemic period, and 24 during the “postpandemic” period that we included in this study. There were 22 subjects who died after laboratory confirmation of influenza A(H1N1)pdm09. No deaths were documented during the first wave. Subjects presenting during the peak of pandemic influenza had a greater incidence of fever (100% vs 77.4%; p<0.001), dry cough (95.7% vs 82.7%; p=0.01), and vomiting (26.1% vs 1.9%, p<0.001) as compared with patients infected during the first wave. The rate of bacterial pneumonia was 18.8% (13/69) during the peak pandemic period and 12.5% (3/24, p=0.754) during the postpandemic period. None of the postpandemic influenza subjects’ intensive care unit stays were due to pneumonia. The hospitalized early 2009 H1N1 pandemic cases and postpandemic cases were milder compared with those at the peak of pandemic activity.

Garengeot’s hernia (GH) is defined as the presence of the appendix inside a femoral hernia. It occurs in 0.9% of femoral hernias and is usually an incidental finding during surgery. Its treatment is controversial and the aim of this article is to review the diagnostic methods and surgical considerations. We report two cases diagnosed preoperatively by contrast-enhanced computed tomography (CT) and discuss the treatment options based on a review of the literature published in PubMed updated on 1 December, 2015. Fifty articles reporting 64 patients (50 women, mean age 70 years) with GH were included in the analysis. Diagnosis was performed by preoperative CT in only 24 cases, including our two. The treatment of GH is emergency surgery. Several options are available laparoscopic or open approach: insertion of a mesh or simple herniorrhaphy, with or without appendectomy. Conslusion The preoperative diagnosis with CT can guide the choice of treatment. Appendectomy and hernioplasty should be performed via inguinotomy, if there is no perforation or abscess formation.

Background Dentinal hypersensitivity (DH) is a diagnostic and therapeutic problem that is now appearing more frequently in modern dentistry. The aim of this work was to elaborate formulation of a new, original desensitizing preparation with prolonged action based on the knowledge of similar commercializations and to compare their performance in vitro. Methodology The analyses were performed with the aid of NMR spectroscopy. The experimental and commercial preparations were examined in vitro after thermocycling on human teeth by optical microscopy. The presence of the material on tooth tissue, its ability to penetrate into the tooth structure and its layer thickness were subjected to statistical analysis. Results A detailed knowledge on composition of commercial material was achieved from spectroscopic measurements. A new adhesive monomer was synthesized and incorporated into an experimental desensitizing formulation. The new monomer appeared to have comparable performance to the commercial one when regarding the affinity to tooth tissue and resistance to thermocycling. Conclusions The experimental formulation comprising a new adhesive monomer seems to be promising and could be applied in dental practice providing that biocompatibility is satisfactory.

This study retrospectively analyzed the efficacy of hydrogen water in the treatment of neonatal hypoxic-ischemic encephalopathy (HIE) and its effect on serum neuron-specific enolase (NSE), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) levels. Forty newborns with HIE who received treatment from April 2014 to April 2015 were divided into a conventional care group and a hydrogen water group according to the different treatment methods applied. Twenty healthy full-term newborns comprised the control group. In the hydrogen water group, 5-mL/kg hydrogen water was orally administered two days after birth daily for 10 days in addition to conventional treatment. After 10 days, efficacy indicators were examined in the HIE groups. The NSE, IL-6, and TNF-α levels were compared among all three groups. The efficacy indicators were significantly lower in the hydrogen water group compared with the conventional group. Before treatment, the serum NSE, IL-6, and TNF-α levels in the HIE groups were higher than those in the control group. After treatment, these levels in the hydrogen water group were lower than those in the conventional group. Hydrogen water lowers serum NSE, IL-6, and TNF-α levels in HIE newborns, thereby exerting a protective effect.

Xanthogranuloma (XG) of the sellar region is uncommon and is difficult to diagnose based on intraoperative frozen sections. This study is a case presentation and review of the literature, highlighting the need to explore underlying diseases in order to guarantee an accurate patient diagnosis. Herein, we presented the case of a 43-year-old woman who was afflicted with xanthogranuloma of the sellar region; the patient had a history of headache and lengthened menstrual cycles over the 6 months prior to presentation. Endocrinology tests revealed that the patient’s levels of prolactin were high and the MRI of the patient showed a clearly defined sellar mass. As a result, the patient was considered to have prolactinoma prior to undergoing surgery. The tumor was completely removed using a transsphenoidal approach, and intraoperative frozen section revealed histology similar to xanthogranuloma. When the tumor was removed by surgical operation, the patient’s visual field defects and headache were relieved. Although intraoperative frozen section should provide some guidance with regard to the diagnosis, a pathological study is conducted to confirm the actual diagnosis.

Retrograde approach (“fundus first”) is often used in open surgery, while in laparoscopic cholecystectomy (LC) is less frequent. LC, with antegrade access, is done by putting in traction the infundibulum and going up to the fundus before to clip the cystic. Our study analyzes a number of surgical procedures performed by experienced surgeons in laparoscopy. From 2002 to 2015, 1740 laparoscopic cholecystectomies were performed at our Institution. The operative procedure performed since 2002 consists of the incision of the visceral peritoneum from the infundibulum away from Calot’s triangle along the gallbladder bed up to the fundus. Then it continues from the fundus up to the infundibulum. Results: There were no bile duct injuries. Average operative time was 40 min. 22 conversions to an open procedure (1.3%) occurred, in cases of acute cholecystitis and cirrhotic patient. Postoperative stay was mean 2 days with no delayed sequelae on follow up. Conclusions: gallbladder antegrade dissection for laparoscopic cholecystectomy can reduce the time of surgery and is an easier technique to perform. Therefore, it can be proposed as the standard procedure and not only be used for difficult cholecystectomies.

McCune Albright syndrome (MCA) is a rare complication of genetic origin. The authors present a case study of a patient with MCA diagnosed with multifocal fibrous dysplasia in his limb and craniofacial bones. The symptoms of the disease in the patient’s facial and oral tissue and the treatment administered have been described.

Objective To compare the accuracy of ultrasound, sialography, and sialendoscopy for examining benign salivary gland obstructions. Methods In this prospective study, patients with symptoms of obstruction of the major salivary gland duct system presenting at the ENT Clinic University Hospital, Ostrava, from June 2010 to December 2013 were included. All patients (n=76) underwent ultrasound, sialography, and sialoendoscopy. The signs of sialolithiasis, ductal stenosis, or normal findings were recorded after the examinations. Statistical analysis of the sensitivity and specificity of all the methods was performed, as well as a comparison of the accuracy of each method for different kinds of pathology (sialolithiasis or stenosis). Results The sensitivity of ultrasound, sialography, and sialoendoscopy for sialolithiasis findings were 71.9%, 86.7 %, and 100%, respectively. The sensitivity of sialography and sialoendoscopy for stenosis of the duct was 69.0%, and 100%, respectively. The study showed impossibility of ultrasonic diagnostics of ductal stenosis. The sensitivity of sialoendoscopy for both pathologies was significantly higher than that from ultrasound or sialography (p<0.05). The specificity of sialoendoscopy was significantly higher than that from by ultrasound or sialography (p<0.05). Conclusion Sialoendoscopy was the most accurate method for examination ductal pathology, with significantly higher sensitivity and specificity than by ultrasound or sialography.

The purpose of this study was to examine the efficacy rendered with a single dose of live attenuated measles, rubella, mumps, and varicella containing vaccine. We inoculated healthcare workers (HCWs) with a single dose of vaccine to a disease lacking in antibody titer for those not meeting the criteria of our hospital (measles: <16.0 (IgG enzyme immunoassay (EIA)), rubella: ≤1:32 (hemagglutination-inhibition), mumps: <4.0 (IgG EIA), and varicella: <4.0 (IgG EIA)). At 28–60 days after vaccination, the antibody titer was tested again. We included 48 HCWs. A total of 32, 15, 31, and 10 individuals were inoculated with a single dose of measles-containing, rubella-containing, mumps, or varicella vaccine, respectively, and showed significant antibody elevation (9.2 ± 12.3 to 27.6 ± 215.6, p<0.001; 8 ± 1.2 to 32 ± 65.5, p<0.001; 3.0 ± 1.0 to 13.1 ± 8.6, p<0.05; and 2.6 ± 1.3 to 11.8 ± 8.1, p<0.001, respectively). Major side effects were not observed. In a limited population, a single dose of live attenuated vaccine showed elevation of antibody titer without any severe adverse reactions. However, whether the post-vaccination response rate criteria of our university was fulfilled could not be determined owing to limited sample size.

The surgical education in Italy has always been a very important issue. The aim of this article is to bring together the feedback of the definitions of the various components of the learning scheme and to evaluate the importance of the legal point. In March 2016 we performed a literature review. We have also examinated the internet pages of the Italian Department of Education, Health and Medical Order. In Italy the tutor had an unclear role from a legal point of view. He is the person who must be able to perform a specific procedure with expert technical and who must know how to stop the student if this is about to perform a dangerous maneuver. In Italy the ability to work for the trainee is limited in all reality, it depends on several factors including the increase of numbers of medical-legal disputes, the timing, the commitment it requires mentoring and a lack of mentors. Conclusion: In surgery, the problem is greater because of the increasingly of medico-legal implications that we are after surgical procedure. It would be necessary to define a role of the tutor in a regular protocol and a proper assessment of his performance.

To overcome kidney donation, the pool of potentially eligible donors has been widened by using suboptimal organs harvested from living donors or cadavers. These organs may engender health complications as age, risk factors, and pathologies of donors fail to meet the standard donor criteria. After examining a wide array of literature on suboptimal kidney transplants, we evidenced two major issues: the lack of standardized terminology and the lack of longterm data on the health outcomes of both suboptimal living donors and recipients. Consequently, surgeons are still unable to provide patients with thorough information to obtain a well-informed consent. Suboptimal kidney transplantation still remains in its experimental stage, thereby raising many ethical and medico-legal concerns. We suggest that one possible solution to overcome some of the ethical shortcomings of suboptimal kidney donations is to provide living donors and recipients honest, accurate, and thorough information about its health risks. To this aim, we advocate adopting a widely standardized terminology that would embrace the whole concept of suboptimal kidney transplantation, increasing the number of future publications on the health outcomes of living donors and recipients, spurring ethical reflection to improve the experience of suboptimal kidney transplantation and reduce the waiting-list for kidney transplantation.

Detectability of early stages of ectopic pregnancies has increased due to improvements in ultrasonographic and biochemical techniques. Since the patients’ future procreative plans must be taken into consideration when commencing treatment, the goal of this work was to compare the effects of treatment methods and their impact on fertility. The study included 91 patients treated surgically for ectopic pregnancy. The choice of treatment depended on patients’ general condition, ultrasonographic evaluation and serum level of beta-hCG. A combination of laparoscopic and conservative systemic treatment was applied in 70% of cases. More rapid beta-hCG reduction was noted when laparoscopy and intra-oviductal injection of hyperosmolar glucose or methotrexate (MTX) were combined with intramuscular administration of MTX at a dose of 50 mg/m2. Follow-up examination of 66 patients revealed that the greatest number of spontaneous pregnancies (48%) resulted after this combination therapy. We conclude that this combination treatment is safe and provides satisfactory results in terms of future fertility.

Background Surgical informed consent forms can be complicated for patients to read and understand. We created a consent form with key information presented in bulleted texts and diagrams combined in a graphical format to facilitate the understanding of information during the verbal consent discussion. Methods This prospective, randomized study involved 70 adult patients awaiting cholecystectomy for gallstones. Consent was obtained after standard verbal explanation using either a graphically formatted (study group, n=33) or a standard text document (control group, n=37). Comprehension was evaluated with a 9-item multiple-choice questionnaire administered before surgery and factors affecting comprehension were analyzed. Results Comparison of questionnaire scores showed no effect of age, sex, time between consent and surgery, or document format on understanding of informed consent. Educational level was the only predictor of comprehension. Conclusions Simplified surgical consent documents meet the goals of health literacy and informed consent. Educational level appears to be a strong predictor of understanding.

Background Video assisted thoracoscopic (VATS) lobectomy has a demanding learning curve due to its technical complexity and risk of uncontrollable bleeding. We investigated the case number required for gaining technical proficiency by applying cumulative sum analysis on initial VATS lobectomy operations of a single surgeon. Methods CALGB definition was used for the definition of VATS lobectomy. The data of the initial cases evaluated and cumulative sum (CUSUM) analysis was applied to duration of the operations and length of hospital stay. Results Fifty-eight patients underwent VATS lobectomy. Of those 51 were malignant and 7 were benign. Fifty-five of the procedures were lobectomy, 2 were inferior bi-lobectomy and 1 was left upper lobectomy with chest wall resection. CUSUM analysis reached to proficiency at 27 cases for duration of the operations. Conclusions The length of learning curve depends on previous experience of the surgeon on open lobectomy and simpler VATS operations, potential number of VATS lobectomy cases and VATS capability of the surgeon. Depending on these factors, it is possible to obtain technical proficiency with an inferior number of procedures compared with existing literature (50-200).

The aim of this meta-analysis was to evaluate whether there was an association between glutathione S-transferase M1(GSTM1)gene polymorphism and Parkinson’s disease (PD) susceptibility by pooling published data. We performed comprehensive electronic database search for articles published between February12,2015 and April30 2016. The published case-control or cohort studies related to GSTM1 gene polymorphism and Parkinson’s disease susceptibility were screened, reviewed, and included in this meta-analysis. The correlation between GSTM1 gene polymorphism and PD susceptibility was expressed by odds ratio (OR) and its corresponding 95% confidence interval (95%CI). Publication bias was evaluated by Begg’s funnel plot and Egger’s line regression test. All analysis was done by stata11.0 software. After searching the PubMed, EMBASE, and CNKI databases, seventeen case-control studies with 3,538 PD and 5,180 controls were included in the final meta-analysis. The data was pooled by a fixed-effect model for lack of statistical heterogeneity across the studies; the results showed GSTM1 null expression can significant increase the susceptibility of PD (OR=1.11, 95% CI:1.01-1.21, P<0.05). Subgroup analysis indicated GSTM1 gene polymorphism was associated with PD susceptibility in the Caucasian ethnic group (OR=1.15, 95% CI:1.05-1.27, P<0.05) but not in the Asian ethnic group (OR=0.89, 95% CI:0.70-1.12, P>0.05). Begg’s funnel plot and Egger’s line regression test showed no significant publication bias. Based on the present evidence, GSTM1 null expression can significant increase the susceptibility of PD in persons of Caucasian ethnicity.

The international plastination phenomenon has proved to be immensely popular with audiences world-wide. Never before has the human body been exposed to public gaze in such an accessible manner. The exhibitions have perplexed many, included anatomists, some of whom find the display of human bodies unethical. The objective of this study is to review the attention on the use of plastination and exhibition of entire human bodies for non-educational or commercial purposes. The nature of these exhibitions and the uneasy balance between entertainment and education has caused heated debate. The possible legitimacy of the expression of one’s will as far as exhibition purposes isn’t considered sufficient for the indiscriminate use of a corpse despite the ethical necessity of respecting the wishes of individuals based on respect for the deceased. The informed consent of an individual represents only the most basic and minimal prerequisite for the use of the deceased’s body for exhibition purposes, and is absolutely not enough on its own to justify its use in entertainment exhibitions or for the commercialization of the death

Acinetobacter baumannii , a non-fermenting Gram-negative bacterium, is a common pathogen in intensive care units (ICU) that is easily spread through contact and can cause nosocomial outbreaks. This study investigated the risk factors associated with outbreaks of pan-drug resistant Acinetobacter baumannii (PDR-Ab) infection by studying a suspected nosocomial outbreak in a comprehensive ICU in a teaching hospital in China, and discusses the effectiveness of current prevention and control measures. Pathogen detection methods involving pulsed field gel electrophoresis (PFGE) were employed to survey patients infected or colonized with PDR-Ab. An epidemiological investigation was conducted to determine the risk factors for infection or colonization with PDR-Ab between 1 October 2014 and 16 January 2015. The rate of PDR-Ab infection in the ICU was higher during the period from 1 October 2014 to 16 January 2015 than it was between 1 October 2013 and 16 January 2014. Only two cases were confirmed to have the same genotype. Risk factors were explored and the rate of infection was found to be controlled by interventions targeting these risk factors. A decrease in the number of infections was observed after multiple prevention and control measures were implemented, preventing the outbreak of a nosocomial infection.

Significant progress in the field of nursing has contributed to the widening of range of functions and professional duties of nurses. More frequent lack of nursing personnel has an impact on negative reception of work, it decreases sense of professional satisfaction and increases the level of burden and fatigue. Methods. The study applied the non-experimental method – a descriptive comparative study without a control group. The data was collected on the basis of Polish-language version of a Japanese questionnaire. In order to evaluate the level of physical fatigue the pedometer was used. Results.158 respondents of a group of 160 were included in the statistical analysis. The study group was internally diversified. The research project assessed the usefulness of the multifactorial analysis in evaluating the main components of nursing fatigue. Multifactorial analysis has shown that mental fatigue concentrated with changes in activeness, motivation and physical fatigue are strongly correlated with age, professional experience and education. Conclusion. Nursing is a profession of a special character and mission. Regardless of the place of work, nursing staff should be given the possibility of pursuing their profession under conditions ensuring the sense of security and protecting them from harmful effects on health.

In 2007, Romania implemented a national program for smoking cessation, providing medication and counseling, entirely for free. The present study focuses on the results of the program among participating smokers treated in three smoking cessation centers from three main cities of Romania: Iasi, Targu Mures and Cluj. Telephone interviews of 832 subjects from three databases of the Romanian cessation clinics of Iasi, Cluj and Targu Mures cities were conducted. These interviews were based on a standard Romanian guideline follow-up questionnaire. At 3 months follow up, abstinence was quite high (53.4%); at 12 months post quit date the study found 18.6% still abstinent subjects. More severely addicted smokers have quit with varenicline and the most difficult category of patients was represented by heavy smokers with respiratory co-morbidities. 61.5% of smokers and 97.2% of non-smokers were willing to receive relapse prevention counseling. Many subjects achieved a long duration partial abstinence (154 days ± 180 SD abstinence days). This is the first study in Romanian smoking cessation centers to analyze the long term impact of fully reimbursed smoking cessation, covering three months pharmacotherapy and counseling. Providing smoking cessation for free had a positive long term impact on program participants.

The aim of this meta-analysis was to evaluate the clinical efficacy and safety of tripterygium glycosides in treatment of stage IV diabetic nephropathy. Methods Through searching the PubMed and CNKI databases, the open published clinically controlled trials related to efficacy and safety of tripterygium glycosides in the treatment of stage IV diabetic nephropathy were collected. The pooled total efficacy, 24h urinary protein, serum creatinine and tripterygium glycosides related toxicity were calculated using Stata 11.0 software. Results Fourteen publications including 992 subjects (512 in the experimental group and 480 in the control group) were included in this study. Eight studies reported the total clinical efficacy comparing the experiment and control groups. No significant statistical heterogeneity was found in total efficacy (I 2 =24.9%, p>0.05). Thus, the combined odds ratio (OR) was pooled by fixed effect model. The pooled OR=4.16 with its 95% CI 2.71~6.37 (p<0.05), which indicated the total efficacy in the experiment group, was significant higher than that of control group (p<0.05); Thirteen studies reported the post-treatment 24h urinary protein value. Statistical heterogeneity analysis indicated significant heterogeneity across studies (I 2 =91.1%, p<0.05); that data was pooled by a random effects model. The combined standardized mean difference (SMD) was -1.55 with its 95% I -2.06~1.03, (p<0.05). The results indicated that post-treatment 24h urinary protein in the experiment group was significant lower than that in control group (p<0.05); Ten studies reported the post-treatment serum creatinine. Significant heterogeneity existed across those studies (I 2 =82.3%, p<0.05). Thereafter, the data was pooled by a random effect model. The combined standardized mean difference (SMD) was −0.24 with its 95%CI −0.40~0.09, (p<0.05). The results indicated that the post-treatment serum creatinine in experiment group was significant lower than that of control group (p<0.05); Eight studies reported tripterygium glycoside-associated toxicity such as liver function damage, gastrointestinal reactions and menstrual disorders. With no statistical heterogeneity among the studies, the data was pooled by fixed effect model. The pooled OR=6.42 (95%CI 2.23~18.48, p<0.05). The pooled results showed the tripterygium glycoside- associated toxicity incidence rate was significant higher in the experiment group than that of the control group (p<0.05); There were no publication bias for effect size of total efficacy, 24h urinary protein, and serum creatinine. However, for tripterygium glycoside-related toxicity, the publication bias was significant (t=-3.55, p<0.05). Conclusion The present evidence shows that tripterygium glycosides can improve clinical efficacy, reduce the 24h urinary protein and serum creatinine, but that they increase the tripterygium glycoside-related toxicity in treatment of stage IV diabetic nephropathy.

Intra-abdominal adhesions are the most frequently occurring postoperative complication following abdomino-pelvic surgery. Abdominal and pelvic surgery can lead to peritoneal adhesion formation causing infertility, chronic pelvic pain, and intestinal obstruction. Laparoscopy today is considered the gold standard of care in the treatment of several abdominal pathologies as well as in a wide range of vascular diseases. Laparoscopy has several advantages in comparison to open surgery. These include rapid recovery times, shorter hospitalisation, reduced postoperative pain, as well as cosmetic benefits. The technological improvements in this particular surgical field along with the development of modern techniques and the acquisition of specific laparoscopic skills have allowed for its wider utilization in operations with fully intracorporeal anastomoses. Postoperative adhesions are caused by aberrant peritoneal healing and are the leading cause of postoperative bowel obstruction. The use of anti-adherence barriers is currently being advocated for their prevention. The outcome of the investigation showed adhesion formation inhibition without direct detrimental effects on anastomotic healing. Poor anasto-motic healing can provoke adhesions even in the presence of anti-adhesion barriers. This review gives a short overview on the current evidence on the pathophysiology and prevention of peritoneal adhesions.

Lymphedema is a chronic disease with a progressively ingravescent evolvement and an appearance of recurrent complications of acute lymphangitic type; in nature it is mostly erysipeloid and responsible for a further rapid increase in the volume and consistency of edema. The purpose of this work is to present our experience in the minimally invasive treatment for recurrence of lymphedema; adapting techniques performed in the past which included large fasciotomy with devastating results cosmetically; but these techniques have been proposed again by the use of endoscopic equipment borrowed from the advanced laparoscopy surgery, which allows a monoskin access of about one cm.

At present time, both CT and MRI are valuable techniques in the study of the thoracic aorta. Nowadays, CT represents the most widely employed technique for the study of the thoracic aorta. The new generation CTs show sensitivities up to 100% and specificities of 98-99%. Sixteen and wider row detectors provide isotropic pixels, mandatory for the ineludible longitudinal reconstruction. The main limits are related to the X-ray dose expoure and the use of iodinated contrast media. MRI has great potential in the study of the thoracic aorta. Nevertheless, if compared to CT, acquisition times remain longer and movement artifact susceptibility higher. The main MRI disadvantages are claustrophobia, presence of ferromagnetic implants, pacemakers, longer acquisition times with respect to CT, inability to use contrast media in cases of renal insufficiency, lower spatial resolution and less availability than CT. CT is preferred in the acute aortic disease. Nevertheless, since it requires iodinated contrast media and X-ray exposure, it may be adequately replaced by MRI in the follow up of aortic diseases. The main limitation of MRI, however, is related to the scarce visibility of stents and calcifications.

In this report we describe a case of pulmonary epithelioid hemangioendothelioma (PEH) in a young woman. The neoplasm manifested with dry cough, chest pain, finger clubbing, and multiple bilateral pulmonary nodules on chest x-ray and computed tomographic (CT) scan. She underwent thoracoscopy, and the histological features of the lung biopsies were initially interpreted as consistent with a not-well-defined interstitial lung disease. Our patient was clinically and radiologically stable over a period of four years, after which the disease progressed to involve not only the lung but also mediastinal lymph nodes, liver and bone. Fiberoptic bronchoscopy showed subtotal occlusion of the right middle and lower lobe bronchi. The histologic examination of bronchial biopsies revealed a poorly differentiated neoplasm immunohistochemically positive for vimentin and vascular markers CD31, CD34 and Factor VIII. A diagnosis of malignant hemangioendothelioma was made. Positron emission tomography (PET) is more sensitive than CT scan and bone scintigraphy in detecting PEH metastases. Furthermore, 18-fluorodeoxyglucose (FDG) uptake seems to be related to the grade of malignancy of PEH lesions. Therefore, we suggest that FDG-PET should be included in the staging system and follow-up of PEH.

Congenital defects of the sternum are rare and due to a failure of midline development and fusion of the sternal bones. Surgical correction of a sternal cleft should be preferred during infancy for functional reasons. Chest wall reconstruction represented a complex problem in the last decades. We report our successful outcome of sternal reconstruction in a rare case of PHACES syndrome, in which the patient was submitted to reconstruction of the sternum and complete closure of the thoracic defect by the employ of an extracellular matrix XCM Biologic tissue matrix. We promote the use of extracellular matrix in surgical reconstruction of chest defects for its maneuverability, plasticity, tolerability and the possibility of growing with the children’s chest getting a good compliance and optimal cosmetic results.

Congenital cystic lung lesions are a rare but clinically significant group of anomalies, including congenital cystic adenomatoid malformation (CCAM), pulmonary sequestration, congenital lobar emphysema (CLE) and bronchogenic cysts. Despite the knowledge of these lesions increasing in the last years, some aspects are still debated and controversial. The diagnosis is certainly one aspect which underwent many changes in the last 15 years due to the improvement of antenatal scan and the introduction of 3-D reconstruction techniques. As it is known, a prompt diagnosis has an essential role in the management of these children. The new imaging studies as 3D Volume rendering system are the focus of this paper. We describe our preliminary experience in a case of hybrid lung lesion, which we approached by thoracoscopy after a preoperative study with 3D VR reconstruction. Our final balance is absolutely positive.

Introduction To study the impact on adult’s fertility of serum inhibin B levels in adolescent patients with idiopathic varicocele after minimally invasive surgical correction and to compare fluctuation of pituitary-testis hormonal values and testicular volumes. Materials and Methods: A case-control study was carried out on a group adolescent patients (n=60) affected by idiopathic left varicocele (group V) and compared with control adolescents (n=40) in the Paediatric Surgery Section of Siena (from June 1993 till September 2013). Inhibin B levels and testicular volume before (T0) and after at 6 and 12 months from surgery (T1 and T2) were evaluated. Results: A positive correlation between testicular growth at T1 and T2 (P<0.001) was found. Linear regression analysis showed a positive correlation between inhibin B levels and testicular volume (expressed as the sum of the right and left values) (P<0.0001). Conclusions: Inhibin B levels are a valid marker for studying the effects of varicocele on the testicular function and confirm the necessity of early surgical correction for preventing the trophic testicular damage and male infertility.

Hereditary spherocytosis (HS) and Chronic myelocytic leukemia (CML) are both life threatening hemotologic diseases. They are rarely seen to occur simultaneously in one individual patient. Here we demonstrate a case of HS associated with CML in this study. The patient is a young female, diagnosed with HS in 2005, and was given partial embolization of the splenic artery. She got significant remission after the procedure. In 2008, she was found abnormal in blood routine test, after bone marrow routine, chromosome and fusion gene tests, she was diagnosed with CML (chronic phase). She did not receive regular treatment until 3 months prior, and is currently being treated with Dasatimib. She achieved hematological remission, but had no significant improvement in chromosome and fusion gene figures. Due to her severe condition of hemolysis, a splenectomy or an allogeneic hematopoietic stem cell transplantation is considered.

Blunt trauma to the neck or to the chest are increasingly observed in the emergency clinical practice. They usually follow motor vehicle accidents or may be work or sports related. A wide pattern of clinical presentation can be potentially encountered. We report the uncommon case of a patient who was referred to our observation presenting with hoarseness and disphagia. Twenty days before he had sustained a car accident with trauma to the chest, neck and the mandible. Laryngoscopy showed a left recurrent laryngeal nerve palsy. Further otolaryngo-logical examination showed no other abnormality. At CT and MR imaging a post-traumatic aortic pseudoaneurysm was revealed. The aortic pseudoaneurysm was consequently repaired by implantation of an endovascular stent graft under local anesthesia. The patient was discharged 10 days later. At 30-days follow-up laryngoscopy the left vocal cord palsy was completely resolved. Hoarseness associated with a dilated left atrium in a patient with mitral valve stenosis was initially described by Ortner more than a century ago. Since then several non malignant, cardiovascular, intrathoracic disease that results in embarrassment from recurrent laryngeal nerve palsy usually by stretching, pulling or compression; thus, the correlations of these pathologies was termed as cardiovocal syndrome or Ortner’s syndrome. The reported case illustrates that life-threatening cardiovascular comorbidities can cause hoarseness and that an impaired recurrent laryngeal nerve might be correctable.

The fibrous tumors of the pleura are rare primary tumors, accounting for 5% of malignant pleural neoplasms, which generally originate from sub-mesothelial mesenchymal tissue of the visceral pleura. These tumours generally exhibit clinical benign behavior although 12% of solitary fibrous tumors can be malignant and have worse outcomes. These tumors are considered “giant” when the lesion > 15 cm. Surgical treatment is the best choice for both benign and malignant neoplasms. We retrospectively analyzed the main case series of giant fibrous tumors of the pleura. In addition we report our experience of a 76-year-old woman treated by pre-surgical embolization involving implantation of vascular plugs. Surgery was successfully carried out without complications; imaging and functional assessment 6 months post intervention demonstrated both the absence of recurrence and improvement of lung function parameters.

Celiac Axis Compression Syndrome by the Median Arcuate Ligament is a very rare condition characterized by chronic postprandial abdominal pain (angina abdominis), nausea, vomiting, which occurs mostly in young patients. The main treatment is a surgical procedure that consists of the division of the arcuate ligament combined with the section of the close diaphragmatic crus and the excision of the celiac plexus. Actually laparoscopic management is feasible and safe.

The persistent hypoglossal artery is rare vascular anomalies. We report the case of a 50-year old man with right hypoglossal artery, ipsilateral hypoplasic internal carotid artery, associated with left proximal subclavian stenosis with subclavian steal syndrome. Power-Doppler-Ultra-Sonography spectral images obtained after the patient exercised the left arm showed mid-systolic deceleration with retrograde late-systolic velocities. A Computed Tomography Angiography demonstrated a proximal stenosis of the left SA, a mild right ICA hypoplasia and an anomalous artery arising from right ICA at C2–C3 level, entering the cranium via the hypoglossal canal and joining the basilar artery. Usually the presence of PHA may be completely asymptomatic, and detected as an incidental finding by CTA or MRA, but in our case its diagnosis is extremely important because it is often the only vessel supplying blood to the basilar trunk and posterior circulation.

The use of contralateral risk reducing mastectomy (CRRM) is indicated in women affected by breast cancer, who are at high risk of developing a contralateral breast cancer, particularly women with genetic mutation of BRCA1, BRCA2 and P53. However we should consider that the genes described above account for only 20-30% of the excess familiar risk. What is contralaterally indicated when genetic assessment results negative for mutation in a young patient with unilateral breast cancer? Is it ethically correct to remove a contralateral “healthy” breast? CRRM rates continue to rise all over the world although CRRM seems not to improve overall survival in women with unilateral sporadic breast cancer. The decision to pursue CRRM as part of treatment in women who have a low-to-moderate risk of developing a secondary cancer in the contralateral breast should consider both breast cancer individual-features and patients preferences, but should be not supported by the surgeon and avoided as first approach with the exception of women highly worried about cancer. Prospective studies are needed to identify cohorts of patients most likely to benefit from CRRM.

Introduction In Italy there has been an increase in claims for damages for alleged medical malpractice. A study was therefore conducted that aimed at assessing the content of the coverage of insurance policy contracts offered to oral health professionals by the insurance market. Material and methods The sample analysed composed of 11 insurance policy contracts for professional dental liability offered from 2010 to 2015 by leading insurance companies operating in the Italian market. Results The insurance products analysed are structured on the “claims made” clause. No policy contract examined covers the damage due to the failure to acquire consent for dental treatment and, in most cases, damage due to unsatisfactory outcomes of treatment of an aesthetic nature and the failure to respect regulatory obligations on privacy. Discussion On entering into a professional liability insurance policy contract, the dentist should pay particular attention to the period covered by the guarantee, the risks both covered and excluded, as well as the extent of the limit of liability and any possible fixed/percentage excess. Conclusions When choosing a professional liability contract, a dentist should examine the risks in relation to the professional activity carried out before signing.

Introduction Obtaining a valid informed consent in the medical and surgical field is a long debated issue in the literature. In robotic surgery we believe in the necessity to follow three arrangements to make the informed consent more complete. Material and methods This study presents correlations and descriptions based on forensic medicine concepts research, literature review, and the proposal of an integration in the classic concept of informed consent. Conclusion In robotic surgery we believe in the necessity to follow three arrangements to make the IC more complete. Integrate the information already present in the informed consent with data on the surgeon’s experience in RS, the number of procedures of the department and the regional map of expertises by procedure.

Robotic surgery (RS) technology has undergone rapid growth in the surgical field since its approval. In clinical practice, failure of robotic procedures mainly results from a surgeon’s inability or to a device malfunction. We reviewed the literature to estimate the impact of this second circumstance in RS and its consequent legal implications. According to data from the literature, device malfunction is rare. We believe it is necessary to complement surgical training with a technical understanding of RS devices.

Aim of the present paper is the review of the principal complications associated to endocrine neck surgery considering how expertise, full adoption of guidelines, appropriate technology and proper informed consent may limit the medicolegal claims at the light of the incoming new regulation of the medical professional legal responsibility. A literature search, using the Medline/PubMed database for full-length papers, was used. Postoperative recurrent laryngeal nerve (RLN) palsy and hypoparathy-roidism remain the principal causes of surgical malpractice claims . In the procedure of neck lymphadenctomy intra-operative haemorrhage, thoracic duct injury, injuries to loco-regional nerves can be observed and can be source of claims. After many years of increased medicolegal litigations, the Italian government is proposing a drastic change in the regulations of supposed medical malpractice in order to guarantee the patient’s right to a safe treatment and in the meantime to defend clinicians from often unmotivated and prejudicial legal cases. Surgical errors and complications in neck surgery are a relevant clinical issue. Only the combination of surgical and clinical expertise, application of guidelines, appropriate technology and a routinely use of specific informed consent can contain potential medicolegal implications.

Introduction Iatrogenic splenic injury is a recognized complication in abdominal surgery. The aim of this paper is to understand the medico-legal issues of iatrogenic splenic injuries. We performed a literature review on PubMed and Scopus using iatrogenic splenic or spleen injury and iatrogenic splenic rupture as keywords. Iatrogenic splenic injury cases were identified. Most cases were related to colonoscopy, but we also identified cases related to upper gastrointestinal procedures, colonic surgery, ERCP, left nephrectomy and/or adrenalectomy, percutaneous nephrolithotomy, vascular operations involving the abdominal aorta, gynecological operation, left lung biopsy, chest drain, very rarely spinal surgery and even cardiopulmonary resuscitation. There are several surgical procedures that can lead to a splenic injury. However, from a medico-legal point of view, it is important to assess whether the cause can be attributed to a technical error of the operator rather than being an unpredictable and unpreventable complication. It is important for the medico-legal expert to have great knowledge on iatrogenic splenic injuries because it is important to evaluate every step of the first procedure performed, how a splenic injury is produced, and whether the correct treatment for the splenic injury was administered in a judgment.

In recent years in Italy (and in the other European Countries) a new debated topic involves anatomists and the scientific world: donation of the body after death for scientific purposes. The aim of our analysis is to analyze the issue of voluntary body donation in Italy focusing first of all, on key principles of the disciplines of donation. Considering the rise of exhibitions and events in which death is spectacularized, the debate is focus on will, on respect and overall on the purpose for which the body is donated. Anatomical dissection is considered necessary in the direct learning of the human body, of surgical practices and new scientific techniques but the scarcity of programmes and regulations regarding the donation of bodies for study and research make it an uncommon practice. After discussing what are the constitutional principles underlying the issue we want to emphasize the need of a more effective and updated regulation to set limits and methods of a practice still essential for scientific progress.

Cosmetic surgery is one of the two branches of plastic surgery. The characteristic of non-necessity of this surgical speciality implies an increased severity in the evaluation of the risk-benefit balance. Therefore, great care must be taken in providing all the information necessary in order to obtain valid consent to the intervention. We analyzed judgments concerning cosmetic surgery found in national legal databases. A document of National Bioethics Committee (CNB) was also analyzed. Conclusion: The receipt of valid, informed consent is of absolute importance not only to legitimise the medical-surgical act, but it also represents the key element in the question concerning the existence of an obligation to achieve certain results/use of certain methods in the cosmetic surgery.

In Italy, Law 194 of 22 May 1978 provides for and regulates the voluntary termination of pregnancy (VTP). Medical abortion became popular nationwide after Mifepristone (RU-486) was authorized for the market by AIFA (Italian Drug Agency) in July 2009. We searched articles in medical literature database with these terms: “medical abortion”, “RU486”, “surgical abortion”. We also searched laws and judgments concerning abortion in national legal databases. Ministerial guidelines were searched on official website of Italian Ministry of Health. We found many medical studies about medical and surgical abortion. We found also ministerial and regional guidelines, which were analyzed. From the point of view of legal medicine, the issues related to abortion with the pharmacological method consist in verifying compatibility and consistency with the safety principles and the parameters imposed by Law n. 194 of 1978, using off-label Misoprostol, what inpatient care should be used and informed consent. The doctor’s job is to provide the patient with comprehensive and clear information about how the procedure will be performed, any complications and the time period needed for both procedures.

The management of older patients with chronic primary immune thrombocytopenia (ITP) is still very challenging because of the fragility of older patients who frequently have severe comorbidities and/or disabilities. Corticosteroid-based first-line therapies fail in most of the cases and patients require a second-line treatment, choosing between rituximab, thrombopoietin-receptor agonists and splenectomy. The choice of the best treatment in elderly patients is a compromise between effectiveness and safety and laparoscopic splenectomy may be a good option with a complete remission rate of 67% at 60 months. But relapse and complication rates remain higher than in younger splenectomized ITP patients because elderly patients undergo splenectomy with unfavorable conditions (age >60 year-old, presence of comorbidities, or multiple previous treatments) which negatively influence the outcome, regardless the hematological response. For these reasons, a good management of concomitant diseases and the option to not use the splenectomy as the last possible treatment could improve the outcome of old splenectomized patients.

The authors evaluated the role of endoscopic techniques in the diagnosis and in the potential treatment of neuroendocrine tumors (NET) localized in the gastro-entero-pancreatic system, on the basis of their experience and of the international literature. NET are rare tumors that arise from neuroendocrine cells of the gastrointestinal tract and pancreas. It is a possibility that both the digestive endoscopy and EUS play an important role in the diagnosis, staging and surveillance of this disease. In some cases, especially in the early stages, surgical endoscopy allows the treatment of such tumors.

Autoimmune hemolytic anemia (AIHA) is a rare hematologic disease, primarily affecting adults or children with immunodeficiency disease. First-line therapy consists of long course of steroids administration, with an early complete response rate (CRr) of 75-80%, but up to 20-30% of patients requires a second-line therapy. Rituximab is the first choice in refractory old AIHA patients, because of its safety and efficacy (early CRr at 80-90% and at 68% at 2-3 years). For this reason, splenectomy is even less chosen as second-line therapy in elderly, even though laparoscopic technique decreased complication and mortality rates. However, splenectomy can be still considered a good therapeutic option with a CRr of 81% at 35.6 months in patients older than 60 year-old, when rituximab administration cannot be performed.

Introduction The frequency of gastroesophageal reflux disease (GERD) is increasing, in part through easy inspection of the upper digestive tract, but especially for a real spread of the disease as a consequence of modernity, lifestyle, incorrect dietary rules, and stress arising from social norms. It is a common chronic gastrointestinal disorder in Europe and the United States. Materials and methods The aim of our study is to highlight a relationship between gastroesophageal reflux disease and salivary pH as evidenced by indicator strips, especially in the outpatient field. Twenty adult subjects (10 males and 10 females) aged between 18 and 50 years (GROUP A)_ were selected. How to control a homogeneous group of 20 patients without GERD, or from any type of allergies (GROUP B) was enlisted. Results This method has provided excellent results showing no difference in the measured values compared with the traditional instrumental measurement. Conclusion Our study has allowed us to observe a strong correlation between the saliva pH, nasal cavities and the interaction between the two districts, and could be the basis for a diagnosis of GERD especially in primary health care clinics and in the initial stage of the disease.

A 82-year-old patient with dyspnea and a recurrent history of pleural effusion was admitted into our unit. He performed a Chest computed tomography showing right pleural effusion. Video-assisted thoracoscopy (VATS) exploratory showed parietal pleural thickening of adipose tissue. The surgical procedure consisted, therefore, in the execution of multiple biopsies of the parietal pleura which appeared covered, on the whole surface, by islands of adipose tissue, without macroscopic pathological aspects. After the procedure was performed pleurodesis with talc. The definitive histological examination consisted of normal mesothelial cells surrounded by fatty tissue infiltrated by small lymphocytes in a patient without skin lesions or visceral or systemic signs of inflammatory involvement of the adipose tissue. We reported a rare case of idiopathic pleural panniculitis with recurrent pleural effusion not associated with Weber-Christian disease.

Obesity is considered a chronic disease, difficult to treat, and is the first cause of death in the world that is predictable. The surgical approach is limited to patients with severe obesity but there is an intermediate group who are not candidates for immediate surgery. The BioEnterics Intragastric Balloon (BIB) is recommended for weight reduction as a bridge to bariatric surgery. All patients in the study underwent a psychological evaluation prior to placement of the BIB.

Aim of the study is to highlight difficulties faced by an inexperienced surgeon in approaching endorectal-ultrasound, trying to define when learning curve can be considered complete. A prospective analysis was conducted on endorectal-ultrasound performed for subperitoneal rectal adenocarcinoma staging in the period from January 2008 to July 2013, reported by a single surgeon of Department of Oncology, Section of General Surgery, “San Luigi Gonzaga” Teaching Hospital, Orbassano (Turin, Italy); the surgeon had no previous experience in endorectal-ultrasound. Fourty-six endorectal-ultrasounds were divided into two groups: early group (composed by 23 endorectal-ultrasounds, made from January 2008 to May 2009) and late group (composed by 23 endorectal-ultrasound, carried out from June 2009 to July 2013). In our experience, the importance of a learning curve is evident for T staging, but no statystical significance is reached for results deal with N stage. We can conclude that ultrasound evaluation of anorectal and perirectal tissues is technically challenging and requires a long learning curve. Our learning curve can not be closed down, at least for N parameter.

Hydatid disease (HD) is caused by Echinococcus Granulosus (EG), which is a larva endemic in many undeveloped areas. The most common target is the liver (59%–75%). The retroperitoneal space is considered as a rare localization. We report an uncommon case of HD located in the adrenal gland space. Presentation of case. This is a 78-year-old Moroccan woman, with right flank pain for eight months previously. She denied contact with dogs or sheep. Her physical examination was normal. There was no pathological alteration of laboratory exams. CT scan measuring 5 cm without clear signs for a sure diagnosis found a round lesion in the right adrenal gland. An abdominal MRI showed a round mass of 34 x 27 mm with fluid component without a clear plane of dissection from kidney and liver. A laparoscopic procedure was performed to obtain a histological diagnosis. We reached a conclusive diagnosis of Hydatid cyst of right adrenal gland space. Hydatid cysts often develop in the liver. The location in the adrenal bed is rare without clinical signs related to alteration of the gland’s secretion. Hydatid cyst identification in the adrenal gland space is based on ultrasonography, CT or MRI scans. The differential diagnosis includes various benign and malignant lesions. Laparoscopic procedure is the best approach available to obtain a histological diagnosis and a curative treatment. The best treatment for HD is the pericystectomy. Laparoscopic surgery can guarantee a radical resection of these lesions when it performed by an expert surgeon.

Modern concepts in the world of beauty arise from popular models, beautiful faces of actors document a bi-protrusive asset with high tension for soft tissues. Facial symmetry has been proposed as a marker of development and stability that may be important in human mate choice. For various traits any deviation from perfect symmetry can be considered a reflection of imperfect development. Additionally, bi-protrusive profile is dependent on the hormonal level regardless of male or female sex. The goal of maxillofacial surgery is to provide best results both for aesthetic and functional aspects. Following these new concepts of aesthetic of the face, new surgical procedure by osteodistraction techniques will lead to a very natural result by harmonizing the face also preventing aesthetic decay in aging faces. Ten cases with a feedback on the aesthetic results using the fivepoint scale of Likert after orthognatic surgery performed following distraction new techniques in combination with ancillary surgical procedures. The aesthetic results in all patients were highly satisfactory. All the patients accepted the new aesthetic of the face avoiding elements of discrepancy and consequently medico-legal problems.

Thoracic surgery remains the better therapeutic option for non-small cell lung cancer patients that are diagnosed in early stage disease. Preoperative lung function assessment includes respiratory function tests (RFT) and cardio-pulmonary exercise testing (CPET). Vo2 peak, FEV1 and DLCO as well as recognition of performance status, presence of co-morbidities, frailty indexes, and age predict the potential impact of surgical resection on patient health status and survival risk. In this study we have retrospectively assessed the benefit of a high-intensity preoperative pulmonary rehabilitation program (PRP) in 14 patients with underlying lung function impairment prior to surgery. Amongst these, three patients candidate to surgical resection exhibited severe functional impairment associated with high score of frailty according CHS and SOF index, resulting in a substantial mortality risk. Our observations indicate that PRP appear to reduce the mortality and morbidity risk in frail patients with concurrent lung function impairment undergoing thoracic surgery. PRP produced improvement of VO2 peak degree and pulmonary function resulting in reduced postoperative complications in high-risk patients from our cases. Our results indicate that a preoperative training program may improve postoperative clinical outcomes in fraillung cancer patients with impaired lung function prior to surgical resection.

Descending Necrotizing Mediastinitis (DNM) is a polymicrobic, dangerous and often fatal process, arising from head or neck infections and spreading along the deep fascial cervical planes, descending into the mediastinum. It can rapidly progress to sepsis and can frequently lead to death. It has a high mortality rate, up to 40% in the different series, as described in the literature. Surgical and therapeutic management has been discussed for long time especially in an elderly patient population. The literature has been reviewed in order to evaluate different pathogenesis and evolution and to recognise a correct therapeutic management.

Aging is one of the major risk factors for varicose veins. The same is for Knee and Hip Osteoarthritis. Most of the patients undergoing to Hip (THA) or Knee (TKA) arthroplasty are over sixteen. Varicose veins, excluding thrombophilia, are the most significant risk factors for VTE after THA and TKA. This study investigates on the usefulness of prophylactic treatment of GSV insufficiency in elderly patients undergoing to orthopedic surgery. A retrospective study enrolling 44 over-sixty five patients, undergoing to TKA or THA. 24 patients underwent to traditional surgery and 20 to EVLA. The presence of evident varicosities and/or a saphenic reflux lasting > 500 ms has been considered as operability criterion. Both in surgery and EVLA group has been performed the ablation of visible varicosities and only saphenic refluxing traits. Results: 1 case of symptomatic DVT was recorded after arthroplasty. A statistically significant difference (p = 0.006) of recovery time between surgery and EVLA groups has been detected. There is not a statistically significant difference in long-term recurrence rate between surgery and EVLA. Conclusions: It is useful to program GSV surgery, before treat hip or knee. This study showed a 50% decrease in the incidence of postoperative DVT.

Conventional transbronchial needle aspiration (C-TBNA) is a minimally invasive technique used primarily in the diagnosis and staging of lung cancer. Currently lung cancer is mostly considered a disease of the elderly and the management of this disease in older patients is a growing concern. In this study we aimed to assess the diagnostic yield and safety of C-TBNA in elderly patients. A retrospective review of 88 consecutive C-TBNA procedures for nodal staging in suspected or confirmed primary lung cancer or pathological confirmation in suspected advanced lung cancer was performed. Patients were divided into less than 70 (<70yrs) or 70 and older (≥70yrs) age groups for analysis. There were no significant differences either in the diagnostic yield (69% in patients aged < 70 yrs and 74% patients aged ≥ 70 yrs (p=0.5) nor in the complication rate (respectively 8.8% in patients aged < 70 yrs and 6.9% in patients aged ≥ 70 yrs (p=0.7) between the two age groups. Reported complications were minor bleeding and poor tolerance; no major complications were observed. Based on our experience, C-TBNA represents a useful and safe alternative procedure for the diagnosis and staging of lung cancer in elderly patients.

A well-designed learning curve is essential for the acquisition of laparoscopic skills: but, are there risk factors that can derail the surgical method? From a review of the current literature on the learning curve in laparoscopic surgery, we identified learning curve components in video laparoscopic cholecystectomy; we suggest a learning curve model that can be applied to assess the progress of general surgical residents as they learn and master the stages of video laparoscopic cholecystectomy regardless of type of patient. Electronic databases were interrogated to better define the terms “surgeon”, “specialized surgeon”, and “specialist surgeon”; we surveyed the literature on surgical residency programs outside Italy to identify learning curve components, influential factors, the importance of tutoring, and the role of reference centers in residency education in surgery. From the definition of acceptable error, self-efficacy, and error classification, we devised a learning curve model that may be applied to training surgical residents in video laparoscopic cholecystectomy. Based on the criteria culled from the literature, the three surgeon categories (general, specialized, and specialist) are distinguished by years of experience, case volume, and error rate; the patients were distinguished for years and characteristics. The training model was constructed as a series of key learning steps in video laparoscopic cholecystectomy. Potential errors were identified and the difficulty of each step was graded using operation-specific characteristics. On completion of each procedure, error checklist scores on procedure-specific performance are tallied to track the learning curve and obtain performance indices of measurement that chart the trainee’s progress. Conclusions. The concept of the learning curve in general surgery is disputed. The use of learning steps may enable the resident surgical trainee to acquire video laparoscopic cholecystectomy skills proportional to the instructor’s ability, the trainee’s own skills, and the safety of the surgical environment. There were no patient characteristics that can derail the methods. With this training scheme, resident trainees may be provided the opportunity to develop their intrinsic capabilities without the loss of basic technical skills.

Laparoscopic transabdominal preperitoneal inguinal hernia repair is a safe and effective technique. In this study we tested the hypothesis that self-gripping mesh used with the laparoscopic approach is comparable to polypropylene mesh in terms of perioperative complications, against a lower overall cost of the procedure. We carried out a prospective randomized trial comparing a group of 30 patients who underwent laparoscopic inguinal hernia repair with self-gripping mesh versus a group of 30 patients who received polypropylene mesh with fibrin glue fixation. There were no statistically significant differences between the two groups with regard to intraoperative variables, early or late intraoperative complications, chronic pain or recurrence. Self-gripping mesh in transabdominal hernia repair was found to be a valid alternative to polypropylene mesh in terms of complications, recurrence and postoperative pain. The cost analysis and comparability of outcomes support the preferential use of self-gripping mesh.

Constipation, obstructed defecation, and fecal incontinence are frequent complaints in multiple sclerosis. The literature on the pathophysiological mechanisms underlying these disorders is scant. Using anorectal manometry, we compared the anorectal function in patients with and without multiple sclerosis. 136 patients referred from our Center for Multiple Sclerosis to the Coloproctology Outpatient Clinic, between January 2005 and December 2011, were enrolled. The patients were divided into four groups: multiple sclerosis patients with constipation (group A); multiple sclerosis patients with fecal incontinence (group B); non-multiple sclerosis patients with constipation (group C); non-multiple sclerosis patients with fecal incontinence (group D). Anorectal manometry was performed to measure: resting anal pressure; maximum squeeze pressure; rectoanal inhibitory reflex; filling pressure and urge pressure. The difference between resting anal pressure before and after maximum squeeze maneuvers was defined as the change in resting anal pressure calculated for each patient. Results Group A patients were noted to have greater sphincter hypotonia at rest and during contraction compared with those in group C (p=0.02); the rectal sensitivity threshold was lower in group B than in group D patients (p=0.02). No voluntary postcontraction sphincter relaxation was observed in either group A or group B patients (p=0.891 and p=0.939, respectively). Conclusions The decrease in the difference in resting anal pressure before and after maximum squeeze maneuvers suggests post-contraction sphincter spasticity, indicating impaired pelvic floor coordination in multiple sclerosis patients. A knowledge of manometric alterations in such patients may be clinically relevant in the selection of patients for appropriate treatments and for planning targeted rehabilitation therapy.
