[Q]: Abstract: A retrospective review of hospital records for 333 patients admitted to a large community teaching hospital by family physicians and family practice residents was performed to determine whether teaching programs in family practice led to a significant increase in the cost of care to patients. Three patient populations were identified for comparison: patients admitted by private family physicians when residents were not involved in patient care, patients admitted by the same family physicians while they served as attending physicians on the family practice service and allowed residents to participate in the care of their patients, and patients admitted by residents from the patient population at the Family Practice Center. After taking into account differences in case mix, an analysis of laboratory charges, radiology use, frequency of procedures, and use of consultants showed that the three groups were not different. Family practice residents managed their own patients as cost effectively as physicians in private practice, which suggests that experience alone is not necessary to develop methods of cost-efficient care. When these two groups were combined into a teaching unit, with few exceptions this efficiency was maintained. These results imply that the introduction of family practice residents into patient care does not invariably increase expenses to the patient.

[Q]: Abstract: Definitive treatment of life-threatening hemorrhage associated with blunt pelvic fracture remains controversial. To elucidate this issue, we reviewed 538 consecutive patients admitted with acute pelvic fracture during a 5-year period. Injury mechanism was motor vehicular in 214 (40%), falls in 152 (28%), auto-pedestrian in 92 (17%), motorcycle in 46 (9%), crush in 26 (5%), and assault or skiing in eight (1%). Ninety-two (17%) of these patients required greater than 6 units of blood transfusion during the first postinjury day, and are the primary focus of this report. Twenty-five patients (28%) had unilateral anterior (Group I, n = 20) or posterior (Group II, n = 5) fractures. The remaining 67 patients (72%) had anterior and posterior element involvement on the same side (Group II, n = 38), bilaterally (Group IV, n = 14), or open perineal wounds (Group V, n = 15). The PASG was applied in 47 patients (51%), and controlled hemorrhage in 12 (71%) of the 17 in whom it was used alone to tamponade pelvic bleeding. Peritoneal lavage was performed in 73 patients (79%). Initial aspirate yielded gross blood in 32 patients; 27 (84%) of these required urgent laparotomy. External skeletal fixation was applied in 19 patients; bleeding was controlled in 18 (95%). Pelvic angiography identified active hemorrhage in three patients and selective embolization was successful in two. Sixty-eight (74%) of the high-risk patients survived. Thirteen (54%) of the 24 deaths were attributable to the pelvic trauma, ten were due to recalcitrant bleeding, and three to delayed sepsis.(ABSTRACT TRUNCATED AT 250 WORDS)

[Q]: Abstract: This case illustrates that massive tumor size, ulceration, or history of multiple recurrences are not absolute prerequisites for metastatic BCC. It supports the hypothesis that tumor proximity to major lymphatic systems or large-caliber blood vessels may be of significance. BCCs originating in skin overlying the parotid gland have the potential to penetrate to a rich vascular and lymphatic plexus as well as compromise the integrity of the facial nerve. Early treatment of these neoplasms utilizing accurate methods of microscopic control appears warranted to prevent the serious consequences of recurrences and deep tissue involvement.
