[Abdominal tuberculosis in childhood: the clinical manifestations].
The authors reviewed the histories of 133 patients with abdominal tuberculosis in Instituto Nacional de Salud del Niño (Children's Hospital), Lima, Perú, between 1989 and 1991. We found morbidity higher in scholars (67.4%). Weight lost were present in all cases and malaise in 95.3%, abdominal distension in 83.72% and abdominal pain in 79.06%. Anaemia in 76.06%, ratio albumin/globulin were altered in 74.41% leukocytosis in 67.44%. Evidence of tuberculosis on chest X-ray were detected only in 62.5%.

Development of anxiety symptoms during a deep diving experiment.
Six commercial divers were investigated for anxiety responses during a 29-day, open-sea world record dive at 500 meters of depth. Three of six (50%) divers developed anxiety. The authors emphasize the importance of research on personality traits as possible predictors for the development of anxiety during deep dives of exceptional depth and duration of confinement.

Urban adolescent females' views on the implant and contraceptive decision-making: a double paradox.
Focus groups and in-depth interviews were used to explore the decline in popularity of the contraceptive implant in a clinic-based sample of 41 ethnically diverse, urban, sexually active adolescents. While these teenagers' socioeconomic status and patterns of inconsistent contraceptive use made them potentially ideal implant recipients, they were unlikely to select this method. Negative media reports about the method were less influential than social conditions such as peer perspectives and gender relations. Oral networks that propagated misinformation went unchallenged because of the silence of satisfied users. Personal factors such as future orientation, autonomous decision-making and value of control also influenced contraceptive decision-making.

Biliary lithiasis in the elderly patient: morbidity and mortality due to biliary surgery.
BACKGROUND/AIMS: Diseases of the biliary tract are the most common conditions requiring intra-abdominal surgery in elderly patients. Complications and adverse outcomes of gallstones are more frequent in older people. The present study was undertaken to analyze factors that contributed to overall morbidity and mortality after open cholecystectomy. Laparoscopic surgery and other new techniques were compared with the open method. METHODOLOGY: We studied retrospectively 76 patients that were 80 years and older. Each patient underwent operation in our unit. 40 patients had fewer than 30 days of clinical history, and 69 patients (90.8%) were emergency admissions. From a clinical point of view, 33 patients (43.4%) had jaundice on arrival and 21 (27.6%) fever. The operative findings included gallbladder wall infection in 46 patients (60.5%) and common bile duct stones in 25. Uni- and multivariate analysis was performed to discriminate variables in mortality and morbidity. RESULTS: Nine patients (11.8%) died, and 38 had complications in the postoperative period. The main causes of death were pulmonary complications (4) and multisystem organ failure (3). Morbidity was mainly due to wound infection (14), urinary infection (13) and respiratory disease (10). Three variables influenced morbidity: sex (male), cardiovascular disease and jaundice upon admission. In the regression model only cardiovascular disease and jaundice were of independent influence. The mortality rate was associated with pre-operative jaundice. CONCLUSIONS: Mortality and morbidity are related mainly to preoperative presentation. Jaundice is the main determinant of the outcome.
