[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: Thirty-four of 87 consecutive patients with subarachnoid hemorrhage from a cerebral aneurysm had a premonitory minor leak. There were 12 men and 22 women, aged 25 to 73 years (mean 44.4 years). Twenty-two had a small and 12 had a large aneurysm located on the internal carotid artery (17 cases), anterior communicating artery (10 cases), middle cerebral artery (five cases), and pericallosal artery (two cases). Fifty-two percent of patients with a minor leak from an internal carotid artery aneurysm had ipsilateral, hemicranial, hemifacial, or periorbital pain. Half of the patients initially saw a physician, but in no case was the correct diagnosis made. Twenty-five patients had a major rupture within 24 hours to 4 weeks after findings suggesting a minor leak, with a mortality rate of 53%. Nine other patients were diagnosed by lumbar puncture or computerized tomography (CT) scanning after initial misdiagnosis and were operated on, without mortality, before a major rupture could occur. The CT scans were negative in 55% of patients with a minor leak, but lumbar puncture, when performed, was always positive. A minor leak prior to major aneurysmal rupture is a common occurrence and, if unrecognized, is associated with a high mortality. Computerized tomography scanning is unreliable in diagnosing this event, and lumbar puncture is the examination of choice once intracranial hypertension has been ruled out.

[Q]: Abstract: The sciatic notch/acetabular index and its rule of thumb application was tested on two European skeletal series of documented sex. The results showed poor consistency between documented and estimated sex. Of the two variables comprising the index, it appeared that sciatic notch width was a particularly poor discriminator of sex. It is suggested that this may be due to differences in the relationship between sciatic notch form and body size in different ethnic groups.
