[EX Q]: Abstract: The diagnosis of 5 alpha-reductase deficiency in infancy is reported for the first time in three male pseudohermaphrodites from the Dominican Republic. Basal plasma testosterone to dihydrotestosterone ratios were significantly elevated in two of the three affected infants, and increased markedly in all three infants after administration of hCG. Since urinary etiocholanolone to androsterone ratios could not be determined accurately in this age group, the diagnosis of 5 alpha-reductase deficiency was confirmed by the finding of elevated urinary tetrahydrocortisol (THF) to 5 alpha-tetrahydrocortisol (5 alpha-THF) ratios, as determined by gas chromatography/mass spectrometry, in the affected male infants compared to those in age-matched normal infants. The THF/5 alpha-THF ratios, however, were lower in both the normal children and the affected infants, suggesting increased 5 alpha-reductase activity in infancy. The affected infants had THF/5 alpha-THF ratios comparable to ratios in adult carrier males and significantly lower than ratios in adult homozygotes. Two of the three affected infants are related to the large Dominican kindred we studied previously and initially were raised as females but, after parental counseling, were changed to a male sex of rearing.

[EX Q]: Abstract: In a prospective study, 24 high school football players with isolated Grade III injuries of the medial collateral ligament (MCL) of the knee were treated by conservative management. This included an active rehabilitation program, progressing from immobilization and controlled motion in an orthotic rehabilitation knee brace, to muscle strengthening and agility exercise. A stable knee was achieved in 22 cases; the average recovery time was 29 days. The athletes returned to competitive sports at a mean time of 34 days. These results confirm previous reports of successful nonoperative management of isolated Grade III MCL injuries.

[EX Q]: Abstract: Although 111In-labeled leukocytes have been shown to be a useful technique for detecting infection, it has been postulated that antibiotic therapy may reduce the sensitivity of the leukocyte scan. Many patients with suspected bacterial infections are placed on antibiotics before a definite site of infection has been identified. Three hundred twelve leukocyte scans on 271 patients were retrospectively reviewed and classified as positive or negative, and as to whether or not they were being treated with antibiotics at the time the leukocyte scan was performed. The overall sensitivity, considering all 312 studies, was 90%. One hundred sixty-nine patient studies were on patients receiving antibiotics; 143 studies were on patients not on antibiotics. The sensitivity of the leukocyte scan was 88.7% in patients on antibiotic therapy; it was 92.1% in those who were not receiving antibiotics. The differences in sensitivity between the two groups were not significantly different (p less than 0.05). We conclude that antibiotic therapy does not affect the sensitivity of the 111In-labeled leukocyte scan.
Which is the apt title for the abstract? option1: Effect of antibiotic therapy on the sensitivity of indium-111-labeled leukocyte scans. option2: The effect of neodymium: YAG laser capsulotomy on aqueous humor dynamics in the monkey eye.
