RESUMO
BACKGROUND: The emergence of new synthetic drugs related to peptic ulcer perforation has been reported. Recently an increase in the use of inhaled methamphetamine has been observed and we have described an association of frequent use with peptic disease symptomatology and perforation. AIMS: To determine whether methamphetamine use is a factor related to peptic acid disease and perforation and to establish its demographic variables. MATERIAL AND METHODS: A retrospective, comparative, descriptive, and observational study was carried out through the evaluation of medical records of patients admitted to the Surgery Service with perforated ulcer, within the time frame of January 2002 to March 2005. A descriptive analysis was carried out, along with the Z test, odds ratio, confidence interval, p value and the Student's t test. RESULTS: Forty-two patients were divided into 2 groups: methamphetamine users (n=25) and nonusers (n=17). There was a statistically significant difference in relation to age, which was lower in the methamphetamine user group (38,7 years vs 58,88 years, p=0.0001). In addition, there was a trend in the user group to develop peptic ulcer perforation at earlier ages compared with the nonuser group (p=0.0001). There were no statistically significant differences between the two groups in regard to clinical presentation. CONCLUSIONS: Methamphetamine use is related to ulcer perforation in age groups of younger patients when compared with nonuser patients.

OBJECTIVE: To describe the morbidity and mortality associated with tuberculosis (TB) in human immunodeficiency virus (HIV) infected children in Baja California, Mexico. METHODS: Retrospective review of the medical records of all children with perinatally acquired HIV infection evaluated at Tijuana General Hospital with a diagnosis of TB between 1998 and 2007. The Stegen-Toledo (ST) clinical criteria for the diagnosis of TB were used. RESULTS: A total of 73 HIV-infected children were followed during the study period. Thirteen (18%) children were diagnosed with TB; one was confirmed by culture to be positive. Among these children, the mean ages at HIV and TB diagnosis were respectively 3.6 and 5.3 years. The mean ST score was 8.1; 10/13 had a score of >or=7, or highly probable TB. There were a cumulative 29 hospital admissions prior to TB diagnosis; 24 of these were due to pneumonia. The mean duration of symptoms at TB diagnosis was 73 days. The most common symptoms were cough (92%) and anorexia (85%). Seven patients (54%) had disseminated TB and five (39%) died as a consequence of TB. CONCLUSIONS: We observed high morbidity, hospital utilization and high mortality associated with TB among HIV-infected children in Baja California.

The aim of this study was to evaluate the performance of the rapid antibody test Determine HIV-1/2, in pregnant women at Tijuana General Hospital. Pregnant women seeking prenatal care or admitted in labour had blood drawn for a rapid HIV test (Determine HIV-1/2), enzyme immunoassay (EIA) and Western blot. Between March and November 2003, 1068 women in labour and 1529 women in prenatal care were enrolled. The sensitivity, specificity, positive and negative predictive values were 100%, 99.8%, 77% and 100%, respectively. For women in labour, the mean time between blood collection and rapid test results was 92 minutes (range: 20-205 minutes) compared with 41 hours (range 24-120 hours) for HIV EIA (P = 0.012). All HIV-exposed infants received oral zidovudine. These findings indicate that the rapid test Determine HIV-1/2 has a high sensitivity and specificity in pregnant women. Rapid HIV testing greatly diminishes the time to diagnosis and enables prompt intervention with antiretrovirals at delivery.
