Input: Consider Input: Abstract: Human growth hormone (hGH) levels were measured during rest, prolonged treadmill exercise at 60% maximum O2 uptake (VO2max), and immediate recovery in four groups of subjects (n = 7/group), ages 21-30 yr, classified as male runners (MR), female runners (FR), male controls (MC), and female controls (FC) to determine whether sex differences in the hGH response are related to resting 17 beta-estradiol (E2) and/or cardiorespiratory endurance (CRE). Glucose (Glc), E2, and hGH levels were determined from serial blood samples taken from an intravenous catheter. Glc did not change significantly during exercise, but different trends for the runners (increases) vs. controls (decreases) resulted in higher (P less than 0.01) postexercise levels in the runners. Resting hGH was higher (P less than 0.05) in the FRs and FCs than the MRs and MCs, respectively, and continued to be higher in the FCs (vs. MCs) during the first 30 min of exercise. The MRs achieved higher peak hGH levels and exhibited higher values than the MCs throughout exercise and recovery. There were no statistically significant training differences in the females. The strongest predictors for peak hGH were absolute work load and group (runners vs. controls), both of which combined accounted for 32-36% of the variability (P less than 0.01) in hGH response. Significant sex-related variables (sex, resting E2) accounted for 11-19% of the variability in peak or percent change in hGH, with E2 having a positive effect at rest but a negative effect during exercise.(ABSTRACT TRUNCATED AT 250 WORDS)

Output: Sex and training differences in human growth hormone levels during prolonged exercise.

Input: Consider Input: Abstract: Posterior fourchette lacerations are suggestive of sexual assault, and toluidine blue dye has increased the detection of these lacerations in adult rape victims. This study investigated the use of toluidine blue dye in the pediatric (0 to 10 years) and adolescent (11 to 18 years) patients to detect posterior fourchette lacerations in sexually abused and control populations. Application of toluidine blue dye increased the detection rate of posterior fourchette lacerations from 4% (1/25) to 28% (7/25) (P less than .05, Fisher exact test) in adolescent sexually abused patients and from 16.5% (4/24) to 33% (8/24) (P = .318, Fisher exact test) in pediatric sexually abused patients. Posterior fourchette lacerations occurred with the same frequency in sexually abused adolescents and sexually active controls adolescents. In the pediatric aged population, 33% of the sexually abused group had lacerations detected, whereas none of the control patients had lacerations. The presence of posterior fourchette lacerations in the pediatric aged patient is strongly suggestive of sexual abuse. Toluidine blue increases the detection of posterior fourchette lacerations in children and adolescents (P less than .001, Fisher exact test). The application of toluidine blue dye to highlight posterior fourchette lacerations is an important addition to tools already used in the evaluation of the sexually abused patient.

Output: Toluidine blue in the detection of perineal lacerations in pediatric and adolescent sexual abuse victims.

Input: Consider Input: 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.
Output: Nonoperative management of isolated grade III collateral ligament injury in high school football players.
