[Educational program in schistosomiasis: a model for a methodological approach].

OBJECTIVE: Lack of knowledge is one of the factors responsible for the persistence of infectious diseases in Brazil. This study had the objective of developing, implementing and evaluating a low-cost educational program using schistosomiasis patients as a model. METHODS: This was a descriptive study developed using a population of healthy people (group 1) and schistosomiasis patients (groups 2 and 3), with 20 individuals in each group. Teaching material (illustrated manual and album of leaflets) and a questionnaire consisting of 17 questions to evaluate the groups' knowledge were devised. The questionnaire was applied to groups 1 and 2 before and to group 3 after the educational program. The variables studied were the educational program, level of schooling, age, clinical form of schistosomiasis, symptoms, and the subject's performance when answering the questionnaire. For the statistical analysis, Fisher's exact test and variance analysis with one fixed factor were utilized. RESULTS: The educational program was evaluated in the form of four topics: cycle, clinical presentation, treatment and prevention of the disease. The median number of correct responses to the questionnaire was higher for group 3 than for groups 1 and 2, for all the topics dealt with. This median was also higher for group 2 than for group 1, for all topics except for the item "prevention". CONCLUSIONS: The educational process applied was efficient and improved the knowledge of the disease. It may provide an effective low-cost methodological model that can also be applied to combating other endemic diseases.

[Construction and implementation of nursing actions in the gastroenterology outclinic].

UNLABELLED: The reorganization of the Schistosomiasis Sector of Gastroenterology at UNIFESP started in 1998, when the Nursing Service was implanted. OBJECTIVE: to develop administrative nursing actions, systematization of care and orientation program for the schistosomic patient. METHOD: a descriptive study carried out at the Gastroenterology Outclinic, which attends schistosomic patients of different clinical types. RESULTS AND DISCUSSION: the reorganization of activities in this Sector resulted in the creation of an organizational structure and the implantation of the nursing visit; creation and distribution of explanatory leaflets and development of the Schistosomiasis Education Program; beginning of the database pilot project with all outpatients and an electronic register of the collection of biologic material. CONCLUSION: this initiative opens up a new opportunity for nursing actions and contributes to quality improvement in ambulatory care.

[Serum gamma-glutamyltransferase alteration in hepatic schistosomiasis doesn't correlate with parasitic load and precedes ultrasound alterations].

BACKGROUND: Liver disorders are the major manifestations of schistosomiasis mansoni. Factors that account for increased concentrations of cholestasis-indicating enzymes in the hepatosplenic form of the disease are unknown. OBJECTIVE: To assess the correlation between increased gamma-glutamyltransferase serum levels and both the parasitic load and ultrasound alterations in patients with schistosomiasis. PATIENTS AND METHODS: Twenty-five patients with the chronic form of schistosomiasis were assessed for the presence or absence of increased enzymatic levels, for the parasitic load (low x medium/high) and for ultrasound parameters. Furthermore, analysis of prothrombin time and a platelet count were performed. RESULTS: Of the 25 patients, 13 showed increased gamma-glutamyltransferase plasma levels. No significant correlation was found between increased gamma-glutamyltransferase levels and the parasitic load, or between increased enzyme levels and ultrasound alterations. Nor did the prothrombin index or the platelet count differ between the two groups (normal gamma-glutamyltransferase levels and increased gamma-glutamyltransferase levels). CONCLUSION: The parasitic load explains no rise in gamma-glutamyltransferase plasma levels in patients with the chronic form of schistosomiasis, and conventional ultrasound is not a sensitive method to detect the alteration suggested by the increased enzyme level in those patients.
