Pattern of alcohol consumption and associated factors among adolescents students of public schools in an inner city in Brazil.

OBJECTIVE: To identify issues related to alcohol consumption among students from an inner city in Southeastern Brazil. METHODS: In this cross-sectional study, 638 students from 13 to 17 years old, of which 355 (55.6%) were girls, were randomly selected in 13/40 (32.5%) public schools from November 2009 to August 2010. A structured questionnaire was used to collect personal/family data, and the Alcohol Use Disorders Identification Test (AUDIT) was used to evaluate alcohol consumption. Bivariate analysis and logistic regression were used. RESULTS: It was observed that 516 (80.9%) students have used alcohol in their lifetime, and 115 (18.4%) had hazardous drinking (AUDIT ≥ 8). By crude analysis, the hazardous drinking was associated with age range (16 - 17 years old), age at first alcohol consumption (≤ 12 years old), higher family income, conflicting family environment, absence of religion practice and parents that consume alcoholic beverages. By adjusted analysis, it was observed an association with the age at first alcohol consumption [≤ 12 years old, odds ratio (OR) = 2.5; 95% confidence interval (95%CI) 1.4 - 4.4]. Active sex life was more frequent among those that have used alcohol in their lifetime (OR = 3.3; 95%CI 2.0 - 5.3). Under the influence of alcohol, 22/103 (21.4%) students have not always used condoms. Among all, 25.4% believe that there is no risk in drinking, and 98% had already bought alcoholic beverages. Having the desire to drink after watching alcoholic beverage advertisements was more frequent among adolescents who had already consumed these beverages (OR = 1.7; 95%CI 1.1 - 2.6). CONCLUSION: The alcohol consumption is early and worrying among adolescents, emphasizing the need for awareness of students and their parents and carers to these risks, and also the compliance with the law prohibiting the sale of alcoholic beverages to minors.

[Alcohol use pattern in pregnant women cared for in a public university hospital and associated risk factors]. / Padrão do consumo de álcool em gestantes atendidas em um hospital público universitário e fatores de risco associados.

PURPOSE: To determine the pattern of alcohol use before and during pregnancy and associated risk factors in puerperal women hospitalized in a public university hospital in Southeastern Brazil. METHODS: Between June and September 2009, 493 puerperae were consecutively evaluated. Those with cognitive impairment were excluded from the study. The AUDIT and CAGE questionnaires were used to diagnose alcohol use/abuse before pregnancy, in addition to the T-ACE during pregnancy. Another questionnaire was applied to collect sociodemographic data, such as age, educational level, marital status, and household income. The χ² test was used in the statistical analysis and the Odds Ratio (OR) and 95% confidence interval (95%CI) were calculated. A p-value <0.05 was considered to be significant. RESULTS: Before pregnancy, the CAGE was positive in 50/405 (12.3%) women and the AUDIT identified alcohol use in 331 (67.1%), which was of low risk in 233 (47.3%), risky in 73 (14.8%), and harmful or indicating possible alcohol dependence in 25 (5%). During pregnancy, the CAGE was positive in 53/405 (13.1%) women and the T-ACE in 84 (17%); the AUDIT identified alcohol use in 114 women, which was of low risk in 73 (14.8%), risky in 27 (5.5%), and harmful or indicating possible alcohol dependence in 14 (2.8%). During pregnancy, alcohol use was more frequent (OR=2.8; 95%CI 1.2 - 6.2) among women with a lower educational level (8.8 versus 3.3%) and more frequent (OR=3.8; 95%CI 1.3 - 11.1) among those who did not cohabit with a partner (6 versus 1.7%). Among pregnant women who drank alcohol, 49/114 (43%) were advised to stop drinking. CONCLUSIONS: Alarming alcohol use was observed during pregnancy, especially among pregnant women with a lower educational level and those who did not cohabit with a partner. There was a low frequency of counseling aimed at abstinence and the AUDIT was the instrument that most frequently diagnosed alcohol consumption.

[Validity of serum amylase and lipase in the differential diagnosis between acute/acutized chronic pancreatitis and other causes of acute abdominal pain]. / Validade da amilasemia e da lipasemia no diagnóstico diferencial entre pancreatite aguda/crônica agudizada e outras causas de dor abdominal aguda.

BACKGROUND: Raised serum amylase and lipase levels are observed in several abdominal diseases. AIM: Assessing the validity of serum amylase and lipase for the differential diagnosis between acute pancreatitis/acutized chronic pancreatitis, biliary tract disease, perforated gastroduodenal ulcer and acute appendicitis. PATIENTS E METHODS: Prospective study including 134 individuals: 38 with acute pancreatitis/acutized chronic pancreatitis, 35 with biliary tract disease, 17 with perforated gastroduodenal ulcer and 44 with acute appendicitis, mean age (standard deviation) of 42.4 +/- 17.7, 46.7 +/- 18.3, 47.8 +/- 12 and 33.7 +/- 17.8 years, respectively. Serum amylase and lipase were determined at admission to the emergency department. RESULTS: For the diagnosis of acute pancreatitis/acutized chronic pancreatitis, when the cutt-off levels of serum amylase were set at the upper normal range level or up to 5-fold as high, the sensitivity decreased from 92% to 74%, the specificity increased from 85% to 99%, the positive predictive value increased from 71% to 97%, and the negative predictive value decreased from 96% to 91%. For serum lipase levels similar figures were obtained for sensitivity and negative predictive value, but the specificity and positive predictive value were lower. When the combination of raised serum amylase or lipase were analyzed, a minor increase was observed in sensitivity and negative predictive value. CONCLUSIONS: For the diagnosis of acute pancreatitis/acutized chronic pancreatitis: 1) the best cut-off level for both tests was 2-times the upper normal range; 2) the sensitivities of serum amylase and lipase were similar; 3) the specificity and positive predictive value of serum amylase were slightly higher than observed for serum lipase; 4) the sensitivity but not the specificity increased when at least one between amylase or lipase was raised.

Frequency of Strongyloides stercoralis infection in alcoholics.

Several studies have shown that chronic alcoholics have increased susceptibility to infections due to higher exposure to infectious agents as well as breakdown in their immune defenses. As Strongyloides stercoralis infection is usually more relevant in immunocompromised patients, the aim of this study was to evaluate the frequency of S. stercoralis infection in alcoholics. Thus, coproparasitological examination was carried out in 145 subjects, from which 45 were chronic alcoholics (mean age of 45.7 +/- 11.0 years), 10 were nonalcoholic cirrhotic patients (mean age of 50.2 +/- 13.1 years), and 90 were asymptomatic nonalcoholic subjects (mean age of 46.7 +/- 10.1 years), which served as controls. From the alcoholics, 9 had hepatic cirrhosis, 9 had chronic pancreatitis and 27 had neither cirrhosis nor pancreatitis. For the diagnosis of strongyloidiasis, the Baermann-Moraes and Lutz methods were used in three fecal samples from each subject. Samples were collected at alternated days, and three slides of each sample were analyzed for each method, thus totalizing 2,610 slides examined. The frequency of strongloidiasis in the total alcoholic group (33.3%) and in the subgroups of alcoholics, i.e., patients with hepatic cirrhosis (44.4%), with chronic pancreatitis (33.3%), and those with no cirrhosis or pancreatitis (29.6%) was statistically higher than that found in the control group (5.5%). None of the individuals with nonalcoholic hepatic cirrhosis had S. stercoralis infection. Our results showed that the chronic alcoholism itself is an important factor that predisposes to strongyloidiasis.
