Weight loss methods of high school wrestlers.

PURPOSE: The purpose of this investigation was to assess the weight loss practices of Michigan high school wrestlers at all levels of competition. METHODS: A two-page survey was designed to assess weight loss behaviors of high school wrestlers. It was mailed by the Michigan High School Athletic Association (MHSAA) midway through the wrestling season to all Michigan high schools participating in interscholastic wrestling. RESULTS: Completed surveys were received from 2532 wrestlers. Wrestlers lost an average of 6 pounds during the season. Over 50% of wrestlers lost more than 5 pounds; 27% of wrestlers lost at least 10 pounds; 72% of wrestlers engaged in at least one potentially harmful weight loss method each week of the wrestling season; 52% used at least two methods each week; 12% used at least five methods each week. Weekly use of laxatives, diet pill, or diuretics was reported by 2% of wrestlers. Vomiting to lose weight was done at least weekly by 2% of wrestlers. Wrestlers who engaged in at least one rapid weight loss method per week lost more weight, began wrestling at an earlier age, and reported more binge eating compared with wrestlers who did not report weekly rapid weight loss. CONCLUSION: The majority of Michigan high school wrestlers engaged in at least one potentially harmful weight loss method each week of the wrestling season. Fasting and various methods of dehydration were the primary methods of rapid weight loss. Wrestlers who lost weight each week were more likely to binge eat. Potentially harmful weight loss practices were found to be common at all grades and success levels.

Physical activity and the primary prevention of cancer.

Evidence has been accumulating that suggests that physical activity may help reduce the risk of cancer. Physically active people have been shown to have a decreased rate of all-cancer mortality. The incidence of colon, breast, and perhaps prostate cancer are decreased in more active people when compared with their sedentary peers. Chronic physical activity may decrease tumor risk by its effect on natural immunity, antioxidant defenses, improved energy balance, hormonal changes, or by other unknown mechanisms.

Evaluation of amenorrhea.

Pregnancy is the most common cause of amenorrhea and must be ruled out before proceeding with diagnostic evaluation. A careful history and physical examination may reveal evidence of androgen excess, estrogen deficiency or other endocrinopathies. Serum prolactin and thyroid-stimulating hormone (TSH) levels should be checked in all women who are not pregnant. Galactorrhea by history or on examination and/or an elevated prolactin level should be investigated with an imaging study to rule out a pituitary adenoma. If serum prolactin and TSH levels are normal, a progesterone challenge test should be performed to determine outflow tract patency and estrogen status. In women with hypoestrogenic amenorrhea, indicated by a negative challenge test and a competent outflow tract, serum gonadotropin, follicle-stimulating hormone and luteinizing hormone levels may be measured to determine whether amenorrhea represents ovarian failure or pituitary or hypothalamic dysfunction. Hypothalamic amenorrhea is common in women with a history of weight loss, stress or vigorous exercise. Amenorrheic women with adequate estrogen levels should receive cyclic progesterone. Hormonal therapy and calcium supplementation in hypoestrogenic amenorrhea.

Anterior knee pain: the challenge of patellofemoral syndrome.

Pain in the anterior region of the knee is one of the most common musculoskeletal complaints in children, adolescents and adults. Difficult and frustrating for the patient to endure, the disorder is also difficult for the physician to manage. The precipitating events and the location and duration of the pain are important factors in narrowing the differential diagnosis. A detailed physical examination further aids in the differential diagnosis. The treatment and rehabilitation of patellofemoral dysfunction, the most common cause of anterior knee pain, has four phases--acute, subacute, chronic and maintenance. These phases involve medication, a structured knee exercise program and activity modification before returning to normal activity. More than 80 percent of patients with patellofemoral dysfunction respond well to a nonsurgical approach.

Asymptomatic bacteriuria in pregnancy.

Asymptomatic bacteriuria occurs in 4 to 7 percent of pregnancies and is associated with the development of acute pyelonephritis, preterm labor and low-birth-weight infants. Treatment of bacteriuria prevents up to 80 percent of cases of pyelonephritis and reduces the risk of preterm delivery. All women should be screened for bacteriuria by a urine culture at the first prenatal visit. Women with bacteriuria should be treated with appropriate antibiotics and should be monitored throughout pregnancy to identify recurrences. Women with persistent bacteriuria require antibiotic suppression until delivery and urologic evaluation following delivery. Urologic evaluation during pregnancy is indicated if bacteriuria persists despite antibiotic therapy.

Calcitonin in the treatment of osteoporotic bone pain.

Calcitonin has been observed to have an analgesic effect on painful bone conditions. A case illustrating the antinociceptive effect of calcitonin on bone pain caused by osteoporotic vertebral compression fracture is presented. There is increasing clinical evidence supporting this phenomenon, though few rigorously controlled studies exist. Calcitonin may have an advantage over other analgesics in the treatment of bone pain resulting from an osteoporotic compression fracture, because, in addition to the observed analgesic effect, it is useful in treating the underlying disorder.
