ABSTRACT: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.

A cross-sectional study was conducted to assess the frequencies and characteristics of occupational exposures among medical and nursing students at a Brazilian public university, in addition to their prevention and post-exposure behavior. During the second semester of 2010, a self-administered semi-structured questionnaire was completed by 253/320 (79.1%) medical students of the clinical course and 149/200 (74.5%) nursing students who were already performing practical activities. Among medical students, 53 (20.9%) suffered 73 injuries, which mainly occurred while performing extra-curricular activities (32.9%), with cutting and piercing objects (56.2%), in the emergency room (39.7%), and as a result of lack of technical preparation or distraction (54.8%). Among nursing students, 27 (18.1%) suffered 37 injuries, which mainly occurred with hollow needles (67.6%) in the operating room or wards (72.2%), and as a result of lack of technical preparation or distraction (62.1%). Among medical and nursing students, respectively, 96.4% and 48% were dissatisfied with the instructions on previously received exposure prevention; 48% and 18% did not always use personal protective equipment; 67.6% and 16.8% recapped used needles; 49.3% and 35.1% did not bother to find out the source patient's serological results post-exposure; and 1.4% and 18.9% officially reported injuries. In conclusion, this study found high frequencies of exposures among the assessed students, inadequate practices in prevention and post-exposure, and, consequently, the need for training in “standard precautions” to prevent such exposures.

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 χ 2 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.

SUMMARYIn the present study the frequencies of immunity against hepatitis B (HB) and of potentially contaminating accidents among medical students of a Brazilian public university were evaluated. Of all the 400 students who should have been immunized, 303 (75.7%), 66.3% of whom were women, answered an anonymous, self-administered questionnaire. Serum anti-HBs were determined in 205 of them and titers ≥ 10 UI/L were considered to be protective. A total of 86.8% of students had received three doses of HB vaccine. The frequency of immunity among women (96.4%) was higher (p = 0.04) than that among men (87.7%). Among those who did not have immunity, 12/13 (92.3%) had been vaccinated before entering medical school. Only 11% of the students with complete vaccination had previously verified serological response to the vaccine. A total of 23.6% reported having been somehow exposed to blood or secretions. Among final-year students, this frequency was 45.0%, being similar among men (47.8%) and women (43.2%). Of all these accidents, 57.7% were due to body fluids coming in contact with mucosa and 42.3% due to cut and puncture accidents. The results from this study show that: 1) the frequency of immunity against HB is high among the evaluated medical students, although verification of response to vaccination is not a concern for them; 2) anti-HBs titers should be verified after complete vaccination and on a regular basis, especially by men; and 3) the frequency of potentially contaminating accidents is high.

Alcohol consumption among victims of external causes in a university general hospital ABSTRACTOBJECTIVE: To estimate frequency of alcohol consumption among victims of external causes cared for in a hospital. METHODS:Study performed with victims cared for in a university general hospital in the city of Uberlândia (Southeastern Brazil), between February and August 2004. Blood alcohol content was determined from 85 patients in the emergency room. Other 301 patients, hospitalized in the outpatient clinics, were interviewed about possible alcohol consumption prior to trauma. The Cut-down, Annoyed by criticism, Guilty and Eye-opener (CAGE) questionnaire was applied in both groups. Fisher's exact test was employed to compare frequencies. RESULTS:Blood alcohol content was positive among 31.8% of patients tested, who most frequently required hospitalization (70.4% versus 37.9%; p<0.05). Proportionately, positive blood alcohol content was more frequent (p<0.05) among victims of physical aggression (57.1%) than fall victims (18.2%) or those of traffi c accidents (29.3%). In outpatient clinics, 29.9% of patients mentioned alcohol consumption, proportionately more frequent (p<0.01) among victims of physical aggression (67.4%) than traffi c accident victims (27.8%) or fall victims (19.3%). Among those who had drunk alcohol and were approached in the emergency room or in the outpatient clinics, the following was observed: the majority was male (85.2% and 80.4%), the occurrence of trauma was higher (p<0.05) on weekends (63% and 57.8%) and at night (59.3% and 57.8%), and the CAGE questionnaire was positive among 81.5% and 82.2% of them. CONCLUSIONS:About a third of patients had drunk alcoholic beverages prior to trauma and the majority of them were male. Proportionately, previous alcohol consumption was more frequent among patients who were victims of violence. CAGE results show that most patients, victims of external causes after alcohol consumption, were not occasional drinkers, but probably chronic users or alcoholics.

Given that chagasic patients in the indeterminate form of this disease, can have abnormal motility of the digestive tract and immunologic abnormalities, we decided to assess the frequency of peptic disease and Helicobacter pylori (Hp) infection in these individuals. Twenty-one individuals, 13 males and 8 females, mean age 37.6 +/- 11.1 years, were examined. Biopsies of the duodenum, antrum, lesser and greater gastric curvature and esophagus were performed. The endoscopic findings were of chronic gastritis in 20 (95.2%) patients, duodenal ulcer in 3 (14.3%), gastric and duodenal ulcer in 3 (14.3%), gastric ulcer alone in 1 (4.8%), esophagitis in 5 (23.8%), and duodenitis in 5 (23.8%). The diagnosis of infection by the Hp was done by the urease test and histologic examination. Hp infection was found in 20 (95.2%) individuals: in 20 out of them in the antrum, in 17 in the lesser curvature, and in 17 in the greater curvature. Hp was not found in the esophagus and duodenum. The only individual with no evidence of infection by Hp was also the only one with normal endoscopic and histologic examinations. The histologic examinations confirmed the diagnoses of gastric ulcer as peptic, chronic gastritis in 20 patients, duodenitis in 14, and esophagitis in 9. In this series the patients had a high frequency of peptic disease, which was closely associated with Hp infection.
