Abstract: this study was developed within the context of the project cansan??o - procan- developed by the federal university of bahia, brazil. the study analyzed information concerning cultural patterns which surround the eating habits of the social groups which live in the semi-arid region of bahia. it is an ethnographic study carried out over the period of 1987 to 1990. the subject of the investigation was the cultural aspect of eating habits of female rural workers, observing the strategies of eating survival as concrete actions to ensure the reproduction of the family unit. the fear of imminent illness and death proves to be fundamental references as ways of conceiving life and of defining food habits, supported by their own understanding of their worlds. the food habits in cansan??o reveal a relationship between the body survival and the reproduction of the family unit, permeated by the daily life in a drought-stricken region. the main activity, the work in the fields, subordinated to precarious living conditions, allows the production and reproduction of ways of interpreting life and, in particular, defines various concepts and classifications about the need to provide sustenance to the body. in some areas of cansan??o food is considered linked to its commercial value; however, the phenomenon of drought still remains the determining factor in the food culture of the population and in its concrete actions to solve the lack of food within the family group.

Abstract: paroxysmal nocturnal hemoglobinuria (pnh) is an acquired clonal disease of the hematopoietic stem cell caused by a somatic mutation in the pig-a gene, resulting in the inability of erythrocytes, granulocytes and platelets to protect themselves against complement system mediated lysis. thus, pnh screening tests (ham's test and cd55 e cd59 proteins investigation through gel column agglutination) were evaluated using flow cytometry, a test useful to detect and measure the pnh clone. initially, 63 patients evaluated using the ham's test between january 2003 and december 2004 from the hemope foundation were selected. from these, 15 cases were positive for pnh. the inclusion criterion for cytometry evaluation was a positive ham's test. thus, four patients were included in the study group. furthermore, two cases with clinical symptoms of the disease but with negative results for pnh were included in this group. negative results were explained by the gel test being performed after blood transfusion, giving a suspicion of false negative results. these six cases were submitted to flow cytometry with all cases proving to be positive for the disease as the pnh clone was confirmed, to different degrees, in both erythrocytes and granulocytes. the flow cytometry results proved the limitation of screening tests as well as showing the importance of cytometry in the identification of the intense variations of clone guaranteeing precise diagnosis in previously transfused patients.

Abstract: objective: to determine the impact of transferring a pediatric population to mechanical ventilator dependency units (mvdus) or to home mechanical ventilation (hmv) on bed availability in the pediatric intensive care unit (icu). methods: this is a longitudinal, retrospective study of hospitalized children who required prolonged mechanical ventilation at the mvdu located at the hospital auxiliar de suzano, a secondary public hospital in s?o paulo, brazil. we calculated the number of days patients spent at mvdu and on hmv, and analyzed their survival rates with kaplan-meier estimator. results: forty-one patients were admitted to the mvdu in 7.3 years. median length of stay in this unit was 239 days (interquartile range = 102-479). of these patients, 22 came from the icu, where their transfer made available 8,643 bed-days (a mean of 14 new patients per month). hmv of eight patients made 4,022 bed-days available in the hospital in 4 years (a mean of 12 new patients per month in the icu). survival rates of patients at home were not significantly different from those observed in hospitalized patients. conclusion: a hospital unit for mechanical ventilator-dependent patients and hmv can improve bed availability in icus. survival rates of patients who receive hmv are not significantly different from those of patients who remain hospitalized.

Abstract: objective: to evaluate the prevalence of hepatitis a virus antibodies in hiv-exposed and/or hiv-infected children and adolescents. methods: between september 1996 and august 2002, 352 patients (200 exposed, but not hiv-infected and 152 hiv exposed and infected) were included in this study. these children and adolescents (age ranged between 1 and 14 years) were all followed up at the pediatric aids clinic of the federal university of s?o paulo (unifesp) and had anti-hav antibodies determined by a commercially available elisa method (tests for total anti-hav antibodies and specific igm antibodies) (dia sorin and radim). statistical analyses were done with chi-squared and t test. results: the prevalence of hepatitis a virus antibodies in hiv-infected and hiv-exposed, but uninfected patients was 34% and 19.7%, respectively. we noticed that in the age range between 2 years and 10 years, the group of hiv-infected children presented a higher prevalence of hepatitis a virus antibodies (35.5%) than the group of uninfected children (16.7%) (p = 0.005). in the hiv infected group, children from b and c categories had a prevalence of hepatitis a virus antibodies (40.5%) higher than n and a categories (24.1%) (p = 0.042). mean age did not differ when children from b and c categories were compared with n and a categories (5.18 and 5.66 years, respectively) (p = 0.617). conclusions: the prevalence of hepatitis a virus antibodies in hiv exposed and/or infected children and adolescents between 1 and 14 years old was 26%. considering the possibility of hiv infection aggravation when associated with hepatitis a virus infection, we suggest that hepatitis a virus inactivated vaccine should be administered to these patients.

Abstract: a pilot study for the control of bancroftian filariasis transmission was developed in two areas of recife, brazil, where microfilaraemic prevalence was 10% in 1991. mass treatment with diethylcarbamazine (dec) using low and spaced doses was employed in both areas. in one such instance, dec therapy was associated with vector control using physical measures and periodic treatment of culex breeding sites with the entomopathogen bacillus sphaericus. the vector population density, reaching 60 - 120 culex/room /night before the intervention, was drastically reduced to 4 - 16 culex/room/night, and maintained at this level for more than two years. actions to engage the local school community in the vector control process were implemented, and as a consequence several classroom and extracurricular activities were put into practice, culminating with the effective participation of a team of students called the "vector vigilantes", in the application of control measures against the vector. the enthusiastic involvement of schoolteachers and students pointed to schools as a place amenable to programs such as this.
