One hundred thirteen patients with invasive carcinoma of the vulva underwent radical vulvectomy and bilateral inguinal-femoral lymphadenectomy between 1957 and 1978. Eighteen had unilateral pelvic lymphadenectomy. Thirty-one patients (27.4%) had positive lymph nodes. The corrected actuarial five-year survival for patients with negative nodes was 96%,(More)
Among a cohort of 237 sexually active females aged 14-19 years recruited from community venues in a predominantly Latino neighborhood in San Francisco, California, the authors examined the relation between gang exposure and pregnancy incidence over 2 years of follow-up between 2001 and 2004. Using discrete-time survival analysis, they investigated whether(More)
A dual radioisotopic method was employed to study the rate of gastric emptying of meals in ten males with an average age of 31 years and 10 elderly males with an average age of 76.4 years. All study subjects were fed a standardized 900-g meal labeled with a liquid (111indium-DTPA) and solid (99mtechnetium-tagged liver) phase isotopic marker. There were no(More)
Ten subjects were given self-selected filling meals (mean weight = 1692 g) and meals of 900 and 300 g. The three meals varied in composition and total kcal. Solid and liquid phase gastric emptying was evaluated using 99mTc-sulfur colloid-labeled chicken liver and [111In]DTPA, and emptying was quantitated using the geometric mean of the anterior and(More)
Gastric emptying rates of radiolabeled beef stew meals were measured in 10 healthy, young (median age = 27 years) male subjects on each of three randomly chosen study days. The subjects either (1) stood at rest, (2) walked on an exercise treadmill at 3.2 km/hr, or (3) at 6.4 km/hr during the study while gastric emptying was being monitored by externally(More)
A group of 100 carefully selected chest radiographs was read by ten observers, five experienced and five inexperienced. The radiographs were chosen to present the readers with a disproportionately large number of both subtle abnormalities and nonpulmonary lesions. Each reader was allowed to search the radiographs for as long as appropriate, up to a maximum(More)
Circadian changes in drug absorption have been documented for several orally administered drugs in humans. To determine whether gastric emptying could account for these changes, morning (8 AM) and evening (8 PM) gastric emptying rates were measured in 16 healthy male subjects synchronized with diurnal activity and nocturnal rest. Gastric emptying half-times(More)
This study was designed to assess the relative influence of meal weight and caloric content on gastric emptying of liquid and solid meals in man. A dual radioisotopic method which permits noninvasive and simultaneous measurement of liquid- and solid-phase emptying by external gamma camera techniques was employed. Nine healthy volunteer subjects ingested(More)
Recent statistics suggest approximately 20 percent of the American work force is engaged in shift work. The evidence which is reviewed in this manuscript suggests that shiftworkers are at risk for the development of gastrointestinal diseases or disorders. The susceptibility to shiftwork related gastrointestinal complaints may be related to the disruption of(More)
