[EX Q]: Abstract: The evaluation and treatment of injuries of the ulnar collateral ligament of the metacarpophalangeal joint of the thumb remain controversial. In a retrospective study that was done to assess our ability to determine whether displacement of the ligament (a Stener lesion) was present, we reviewed our accumulated experience with patients who had an injury of this ligament who were treated surgically between 1972 and 1984. Since our method of evaluation changed in 1977, we compared the preoperative and operative diagnoses in the twenty patients who were treated surgically from 1972 through 1976 with those in the twenty patients who were so treated from 1977 through 1984. Considering all forty patients who were treated operatively, sixteen (40 per cent) had a typical Stener lesion, and in two others (5 per cent) the ulnar collateral ligament was rolled up on itself and lying beneath the adductor aponeurosis. From 1972 through 1976, stability was tested with the metacarpophalangeal joint in complete extension or in varying amounts of flexion. Of the twenty thumbs that were evaluated by this technique and were treated surgically, 20 per cent had a Stener lesion. From 1977 through 1984, stability was tested with the joint in full flexion because of the findings in anatomical studies that were completed in 1977; the incidence of a Stener lesion in the twenty thumbs that were treated by repair or reattachment of the ligament during this time was 70 per cent.(ABSTRACT TRUNCATED AT 250 WORDS)

[EX Q]: Abstract: Insulin may mediate the hyperandrogenism that frequently occurs in patients with insulin-resistant states. To test this hypothesis, we studied five normal women and one woman with hyperandrogenism, insulin resistance, and acanthosis nigricans with the hyperinsulinemic-euglycemic clamp technique. Each woman received a 0.1 U/kg insulin bolus dose, followed by a 10 mU/kg X min insulin infusion for 12-16 h. In the normal women, an average insulin level of 1832 +/- 292 (+/- SEM) microU/ml was achieved; serum glucose was clamped at 116 +/- 5 mg/dl. At this level, insulin may bind to the insulin-like growth factor I receptor as well as to its own receptor. Contrary to our working hypothesis, a rise in serum testosterone did not occur in any women during insulin infusion, and in one women, serum testosterone levels decreased. When analyzed as a percentage of the basal value, serum progesterone levels fell 20% in the normal women within the first 2 h of insulin infusion, but did not change thereafter. Dehydroepiandrosterone sulfate (DHEA-S) levels, however, uniformly and progressively decreased by 39% after 12 h of insulin infusion in the normal women and by 31% at 14 h in the woman with hyperandrogenism, insulin resistance, and acanthosis nigricans. The fall in serum DHEA-S levels was not due to diurnal rhythmicity, as the changes in serum DHEA-S levels did not correlated with those in serum cortisol. Suppression of PRL release also was excluded as a cause of the fall in DHEA-S levels. These results indicate that acute hyperinsulinemia of 12- to 16-h duration does not increase serum testosterone or DHEA-S concentrations and, indeed, can cause a decline in serum DHEA-S levels in both normal women and the single woman studied with hyperandrogenism, insulin resistance, and acanthosis nigricans.

[EX Q]: Abstract: The purpose of the study reported here was to provide descriptive information about dean's letters, which are comprehensive summary letters sent near the end of students' undergraduate medical training by medical school deans to be part of the students' residency applications. Deans of student affairs at 124 U.S. medical schools were surveyed regarding composition of these letters at their institution. They were asked to describe themselves and the letters they write. Responses were received from 87 percent of these schools and provided data on types of information included in the letters, the decision to edit evaluations, student participation in the letter-writing process, use of final summary statements, cost and length of letters, and attitudes toward the development of national letter-writing guidelines. Major findings of the survey show that 97 percent of the writers allocated more space for clinical evaluations than basic science evaluations. Less than 50 percent of the writers included the student's class rank. Almost all included narrative evaluations of the student's performance during the clinical years. Negative information on students was addressed inconsistently by the writers. Eighty-five percent of the writers categorized their students in final summary statements, but many of these failed to provide descriptions of the categories used or explanatory data. The present authors make recommendations for writing more credible and useful letters.
