Making medicine for the poor: primary health care interpretations in Pelotas, Brazil.

This paper explores the local political setting in which primary health care and community participation have been implemented in Pelotas, Brazil over the past two decades. We argue that in a medically plural setting with a mixture of private and public health care schemes, capitalist-based principles and ideals (such as the predominant role given to technology) shape generalized concepts of good clinical skills and quality of care, thereby regulating the medical system as a whole. The analysis shows that some women living in shantytowns reject the negative class-based associations made with their communities in a variety of ways, including the non-use of their local primary health care (PHC) centre which they considered to be a poor substitute for what the wealthy take for granted. Recent studies show that primary level antenatal care is of low quality when compared with other sectors. Nevertheless, local politicians and physicians often blamed various aspects of local 'culture' (folk health beliefs, low valuing of biomedicine, lack of modern concepts of community-building and altruism) for failed PHC programmes, contributing a prejudicial feedback cycle between frustrated professionals often engaging in prejudicial clinical practices and offended users. Rather than discuss community participation through vague concepts such as empowerment and citizenship, those involved in PHC reform would do well to take explicit (publicly stated) responsibility for the socio-political, financial and bureaucratic constraints to PHC.

Nutrition counseling increases weight gain among Brazilian children.

To assess the impact on child growth of the nutrition-counseling component of the Integrated Management of Childhood Illnesses (IMCI) strategy, a randomized trial was implemented. All 28 government health centers in a Southern Brazil city were paired according to baseline nutritional indicators. One center from each pair was randomly selected and its doctors received 20-h training in nutrition counseling. Thirty-three doctors were included and 12-13 patients < 18 mo of age from each doctor were recruited. The study included testing the knowledge of doctors, observing consultations and visiting the children at home 8, 45 and 180 d after the initial consultation. Maternal knowledge, practices and adherence to nutritional recommendations were assessed, and anthropometric measurements were taken. Day-long dietary intake was evaluated on a subsample of children. Doctors in the intervention group had better knowledge of child nutrition and improved assessment and counseling practices. Maternal recall of recommendations was higher in the intervention than in the control group, as was satisfaction with the consultation. Reported use of recommended foods was also increased. Daily fat intake was higher in the intervention than in the control group; mean daily intakes of energy and zinc also tended to improve. Children 12 mo of age or older had improved weight gain and a positive but nonsignificant improvement in length. Nutrition-counseling training improved doctors' performances, maternal practices and the diets and weight gain of children. The randomized design with blind outcome evaluation strongly supports a causal link. These results should be replicated in other settings.

[The effects of a cardiac rehabilitation program on 2 populations of coronary patients: acute myocardial infarct and coronary bypass surgery].

UNLABELLED: Cardiac rehabilitation programmes (CRP) have proven beneficial in coronary heart disease. The purpose of this study was to evaluate the effects of our CRP on two coronary heart disease populations: after acute myocardial infarction (AMI-CRP) and after coronary artery bypass surgery (CABG-CRP). Results were compared to control groups (AMI-C and CABG-C). POPULATION: Group AMI-CRP: n = 43 patients, mean age = 48.7 +/- 9.8 years; Group AMI-C: n = 20 patients, mean age = 59.2 +/- 11.5 years; Group CABG-CRP: n = 54 patients, mean age = 54.9 +/- 9.7 years; Group CABG-C: n = 20 patients, mean age = 56.5 +/- 9.9 years. All patients are male and there were no significant differences in ventricular function and coronary disease severity. Parameters were evaluated in the AMI groups at discharge, 3 and 12 months after acute episode; in the CABG groups 3 and 12 months after surgery. RESULTS: Both CRP groups improved their exercise capacity (significantly improved the peak values of METs and double product). A favorable lipid profile change (total cholesterol and HDL) was induced in the CABG-CRP group and more significant in the AMI-CRP group. No significant differences were observed in obesity indexes (body weight and BMI > or = 27.8 Kg/m2). A increase in nonsmokers was important in all groups. Professional reintegration was 91.7% in the AMI-CRP group and 84.4% in the CABG-CRP group. The CRP groups showed a better knowledge of the disease, and a beneficial change in relation to themselves and the world that resulted in a decrease in depression and anxiety. CONCLUSIONS: Participation in our cardiac rehabilitation program, either after AMI or after CABG, improves cardio-respiratory fitness, favorably influences blood lipid profiles, and improves self-reliance and quality of life.

Pyoderma gangrenosum associated with systemic lupus erythematosus: response to pulse steroid therapy.

Pyoderma gangrenosum in a 35-year-old woman with long-standing systemic lupus erythematosus was treated with pulse steroid therapy. Significant improvement in the ulceration and control of the lupus erythematosus occurred. The unusual association of these disorders is reviewed, and the efficacy of pulse therapy in the treatment of refractory cases of pyoderma gangrenosum is discussed.

A case of lymphomatoid papulosis and Hodgkin's disease.

Lymphomatoid papulosis is a unique paradoxic entity characterized by recurrent self-healing papulonodular lesions with histologic features of malignancy. Usually the disease has a protracted benign course; however, it can be associated with or evolve to a lymphoproliferative disorder. Thus "lymphoma-associated papulosis" represents the malignant end of a wide spectrum. We describe a case of a patient with lymphomatoid papulosis who developed Hodgkin's disease 8 years after the onset of skin lesions. Systemic chemotherapy achieved complete remission of Hodgkin's disease, but recurrent papulonodular lesions continued to form in the subsequent 18 months.

[Sycosis of the beard (tinea barbae). Analysis of 42 cases].

42 patients suffering from dermatophytic fungus infection involving the bearded area, face and neck (tinea barbae) were seen in the Clinic between 1970 and 1977. The clinical diagnosis was confirmed by microscopic examination (KOH) of skin and hair scrapings in all the patients. The material obtained from 39 patients and inoculated gave a positive culture; in were isolated and following fungi: T rubrum-18, T. mentagrophytes-16, T. megninii-1, T. violaceum-2, M. canis-2. From the clinical point of veiw it was possible to classify the patients in 3 main types: --Superficial type-11 patients. --Kerion-10 patients (T. mentagrophytes-9, M. canis-1). --Nodular type-deep seated nodules, without discharging, very slow evolution - 21 patients (T. mentagrophytes-4, T. rubrum-13, T. megninii-1, T. violaceum-1). It was obtained material for histology in 13 patients: 3 suffering from kerion and 10 with the nodular clinical type. The histology of the Kerion type showed a marked inflammatory reaction consisting largely of neutrophils surrounding the hair follicles. Only in one examination, out of the 3 patients studied with Kerion, showed fungi, on PAS. The 10 patients suffering from the nodular type of infection who were studied histologically showed a more or less uniform picture, which consisted in a more deep seated infiltration specially consisting of lymphocytes and plasmocytes, on the derme but not so perifollicular as in Kerion and, in 2 cases, there was a tendency to form a tuberculoid structure. The PAS was positive in 6 patients. The fungi were always intrafollicular. All the patients were treated with griseofulvin 1 gr. per day. All of them healed after a period of 4-8 weeks of treatment.

[Treatment of female gonorrhea. Therapeutic results with pivampicillin-probenecid and penicillin procaine-probenecid combinations].

A controlled trial of the relative efficacies of procaine penicillin G and pivampicillin for single dose treatment of uncomplicated gonorrhea in female was performed. Confirmation of the disease was obtained by bacteriological isolation of Neisseria gonorrhea from uretral, cervical or rectal exudates inoculated in suitable media. Based upon their previous experience, the authors used probenecid, along with both antibiotics, as a way of increasing the effectiveness of these drugs. Twentynine patients received probenecid 1 g. followed by oral pivampicillin, in a single dose of 1,4 g. Therapeutical results were evaluated in twenty-four, with clinical and bacteriological cure of eighteen. The other group included fifty-two patients treated with probenecid 1 g. followed by a single intramuscular dose of 3.000.000 U. of procaine penicillin G. The therapeutical results in the last group were evaluated in forty patients, with clinical and bacteriological cure of thirty-three. According to the above mentioned results procaine penicillin G seems to offer a slightly superior probability of cure.

[Tuberculosis treatment adherence in Pelotas, Brazil, from the patient's perspective].

This study deals with adherence to tuberculosis treatment among men and women as well as the disease's links and consequences vis-à-vis life styles and treatment outcomes. The ethnographic study was a component of the Tuberculosis Epidemiological Control Project in the city of Pelotas and aimed to identify the reasons patients failed to complete treatment. Direct ethnographic observations and semi-structured interviews were used. Use of the term "adherence" is justified by the concern for extending to other fundamental factors in addition to the patient's own individual responsibility. This approach fostered an understanding of views towards disease, social dynamics among the various protagonists involved in the disease process, and treatment. Some of the factors considered in adherence to treatment were: socio-demographic characteristics, cultural factors, popular beliefs, the cost-benefit relationship, physical and chemical aspects of the drugs, the physician-patient relationship, and level of family participation in treatment.

[Tuberculosis throughout the times].

This paper outlines a picture of the representations of tuberculosis in different decades and how they have been handled by clinical medicine. The history of the disease, from the early days of the XIX century hygienist policies to the current control and prevention programs, displays a continual change of focus: social views were sometimes highlighted (the environment, work, housing), and at times the focus shifted to individual viewpoints (body fluids, lifestyle) regarding forms of prevention and cure of the disease. Such diverse representations and concepts about tuberculosis have influenced the way in which medicine and sick individuals perceived the disease and dealt with it.
