Civilians and military personnel alike are increasingly being exposed to explosives in war zones and other regions of political conflict and, consequently, they are suffering associated blast-related polytrauma (multiple complex injuries). Although acute, emergency-based medical care for patients with blast-related trauma has been well described, postacute clinical management—which is of greatest interest to primary care physicians and rehabilitation specialists—has not been well discussed or researched. The authors offer a description of the common injuries seen in patients with blast-related polytrauma, as well as a conceptual model of a potential evaluation and treatment strategy in the postacute setting. Although medical evaluation of a patient typically proceeds in a sequential manner based on primary symptoms, the authors advocate a parallel approach to patient evaluation based on mechanism (cause) of injury. Such an approach relies on knowledge of the typical physical and psychological sequelae associated with a particular mechanism of injury to guide patient assessment and treatment. The authors highlight the mechanism-of-injury approach used with patients who have blast-related polytrauma at the Veterans Health Administration's (VHA) Veterans Affairs Medical Center in Tampa, Fla, site of one of the VHA's four Polytrauma Rehabilitation Centers.

Although obstetrically related trauma remains the most common cause of injury to the female genital tract, trauma of nonobstetric origin is not uncommon. Reports of traumatic injuries to the vagina, especially lacerations, have been infrequent in the literature and offer only a generalized approach to this problem. Severe vaginal lacerations may result in life-threatening blood loss. The authors report their recent experience with treating patients who have this type of trauma, review mechanisms of injury, and provide an organized treatment protocol for the nonobstetric patient with suspected vaginal laceration. Preparation for these emergencies circumvents dangerous delays and inadequate examination and treatment.

As increasing numbers of women and osteopathic physicians enter medical practice, it is important to identify their choices in medical specialty and practice location and the implications these choices have for the future of healthcare in the United States. In 2003, data from the Texas Medical Board and the Office of the [Texas] State Demographer were aggregated to compare the rates at which physicians differed in their choices to practice primary care specialties in a rural location. In addition, the impact of sex and type of medical degree on these choices was examined. Analyses revealed that male osteopathic physicians were 2.3 times more likely than all other physician groups to practice rural primary care. Analyses also revealed that female osteopathic physicians were more likely than other physicians to choose primary care as a specialty and were 2.5 times more likely than female allopathic physicians to practice primary care in a rural location. Policies intended to produce primary care or rural primary care physicians should take into account the effects of gender and osteopathic training.

The authors present the case of a 44-year-old American Indian woman with hematemesis, spontaneous cutaneous hemorrhages, and multiple ecchymoses. Coagulation factor analyses demonstrated both prolonged prothrombin time (PT, >40 s) and prolonged partial thromboplastin time (PTT, >120 s). Measurement of the serum level of brodifacoum (37 ng/mL), one of the superwarfarin agents commonly used in rodenticides, confirmed poisoning as the cause of the patient's symptoms. Substantial amounts of fresh frozen plasma and vitamin K were required to obtain normal coagulation parameters and maintain these parameters over a 3-week inhospital period. Oral administration of vitamin K (100 mg daily) maintained normal PT (14.1 s), PTT (33.0 s), and international normalized ratio (INR, 1.48) at 2 weeks after the patient was discharged from the hospital. By 2 months postdischarge, PT, PTT, and INR returned to elevated levels because of patient noncompliance with the prescribed tapering vitamin K regimen.

Bell's palsy is caused by a lesion of the facial nerve and results in unilateral paralysis or paresis of the face. The condition affects approximately 23 in 100,000 persons, with onset typically occurring between the ages of 10 and 40 years. The authors report the case of a 26-year-old woman with Bell's palsy, whom they treated with osteopathic manipulative treatment that was focused on the enhancement of lymphatic circulation. The osteopathic manipulative procedures used involved reducing restrictions around four key diaphragms (thoracic outlet, respiratory diaphragm, suboccipital diaphragm, cerebellar tentorium), as well as applying the throracic pump, muscle energy, primary respiratory mechanism, and osteopathy in the cranial field. The authors, who were guided by the four principles of osteopathic philosophy, report that the patient's symptoms resolved within 2 weeks, during which two sessions of osteopathic manipulative treatment, each lasting approximately 20 minutes, were held. Patient recovery occurred without the use of pharmaceuticals.

The Comprehensive Osteopathic Medical Licensing Examination USA Level 2 Performance Evaluation (COMLEX-USA Level 2-PE) is a national multistation performance examination designed to examine students' osteopathic clinical skills. The current study examines the relationship between achievement levels on the COMLEX-USA Level 2-PE and selected school-related variables for the class of 2005 at the West Virginia School of Osteopathic Medicine in Lewisburg, WVa (N=70). Significant ( P <.01) correlations between the COMLEX-USA Level 2-PE summary performance and selected academic achievement measures include: weighted Physical Diagnosis grade, 0.41; weighted year 1 and year 2 Osteopathic Principles and Practice grade, 0.37: overall year 2 grade point average, 0.42; the objective structured clinical evaluation (OSCE) Physical Examination score, 0.40; and the OSCE Total Station score, 0.33. While further research is needed, the current study found modest but notable relationships between school-generated academic variables and performance on the COMLEX-USA Level 2-PE, and therefore supports the validity of the COMLEX-USA Level 2-PE examination for assessing the clinical skills of future osteopathic physicians.

As part of the standard-setting methods used by the National Board of Osteopathic Medical Examiners for its Comprehensive Osteopathic Medical Licensing Examination clinical skills performance evaluation (COMLEX-USA Level 2-PE), a self-administered survey was distributed electronically and by mail to deans of colleges of osteopathic medicine, directors of graduate medical education programs, osteopathic medical students, and experts chosen demographically to represent osteopathic physicians in the United States. Groups were asked to rate fourth-year osteopathic medical students and interns on their clinical skills and acceptable pass rates and expected pass rates on the COMLEX-USA Level 2-PE. The surveys were not used systematically to compute the passing standards but to provide additional support for their validity. The viewpoints of the deans differed from those of the students, osteopathic graduate medical education program directors, and experts regarding clinical skills proficiencies and acceptable pass rates. However, all of the groups agreed that, on average, some students and interns do not have adequate clinical skills. These results provide additional support for requiring acceptable performance on a comprehensive clinical skills examination before admission to osteopathic graduate medical education programs.
