Com o objetivo de avaliar as características do consumo de medicamentos na população urbana de Araraquara, SP, Brasil, foram coletados dados, por meio de entrevistas domiciliares, de uma amostra da população que consumiu pelo menos um medicamento nos quinze dias que antecederam a data da entrevista. O estudo foi realizado no período de agosto a setembro de 1985. Verificou-se que 42,1% dos medicamentos utilizados foram adquiridos sem prescrição médica. O consumo entre o sexo feminino foi maior que para o sexo masculino. Na automedicação o grupo que apresentou taxa mais elevada, segundo a faixa etária, foi o de 50 anos e mais, com 31,6%. Grande parte do consumo de medicamentos constituiu-se dos industrializados (97,6%). As prescrições médicas, feitas em consultas anteriores, e avalia das como bem sucedidas foram retomadas em situações diversas (12,0%), revelando o importante papel que o médico desempenha na formação dos critérios de escolha dos remédios utilizados nas práticas de automedicação. O farmacêutico e/ou balconista de farmácia contribui com 10,0% dos medicamentos usados que tiveram essa via de indicação. As orientações feitas por amigos, vizinhos e parentes (9,1%) revelaram intenso circuito de trocas de socializações quanto aos quadros móbidos e indicações terapêuticas.

One of the most important problems in the elderly is a nutritional deficiency. Several physiological changes and the use of multiple drugs interfere with appetite, food intake and absorption of nutrients, which can lead to the risk and malnutrition in the elderly, especially among institutionalized. The present study aimed to evaluate the prevalence of malnutrition and risk for malnutrition and its associated factors in institutionalized elderly. The same can be characterized by the type individual, observational and cross-sectional. Obtaining the sample was through the records of individuals of long-stay institutions for the elderly in the city of Natal, RN. The elderly were evaluated through the Mini Nutritional Assessment (MNA) and triceps skinfold (TSF) and each senior or caregiver answered a questionnaire about information like type and dietary restrictions, accessibility to food, use of alcohol and tobacco, practice physical activity and appetite. Variables such as age, gender, education, marital status, time that the elderly living in the institution, the reason for the institutionalization and comorbidities were taken from the records of each senior. The frequency of food consumption of various food groups was assessed from the questionnaire frequency of feeding study Health, Wellbeing and Aging (HWA). Data were presented as means and standard deviations, absolute and relative frequencies. To analyze the frequency of consumption, there was a factor analysis with extraction of factors from the principal components analysis with varimax rotation. A bivariate analysis was performed using the chi-square and the magnitude of the effect observed by prevalence ratio (95% CI). The Poisson regression assessed the net effect of independent variables on the two outcomes, considering a significance level of 5%. We studied twelve Homes for the Aged totaling 381 seniors eligible for the study. The prevalence of risk of malnutrition was 46.1% (45.9 to 46.2) and malnutrition was 31.4% (31.2 to 31.5). The risk of malnutrition was significantly associated with the presence of urinary incontinence (RP = 1.444, 1.113 to 1.874) was associated with malnutrition and lack of appetite (RP = 1.757, 1.246 to 2.476), the fact that the individuals do not have access to food outside the institution (RP = 0.565, 0.337 to 0.946), low water consumption (RP = 1.646, 1.101 to 2.459) and dementia (PR = 1.537, 1.072 to 2.204). The high prevalence of malnutrition and risk of malnutrition in the study suggests that we should pay attention to information related to eating habits and the presence of comorbidities, as these can influence the nutritional status of this population

Objectives: To assess cardiac morphology and function by means of echocardiograms of children with obstructad breathing while asleep.Methods: the study enrolled 40 children of both sexes, aged from 3 to 11 years; 30 of them had obstructed breathing during sleep (group I) and 10 children were healthy controls (group II). The two groups were similar in terms of sex, age, weight and height. The 40 children underwent echocardiogram, viewing all four chambers during systole and diastole, paying special attention to the right ventricle (RV). These data were compared by means of Student's t test (p < 0.05).Results: In group I, increased diameter and area of the right ventricle were observed during both systole and diastole. There was less variation in RV area between systole and diastole. Reduced left ventricle (LV) diastolic diameter was also observed, together with reduced ejection fraction and reduced contraction.Conclusions: the morphological and functional cardiac abnormalities observed in the RV and LV suggest that, in children, obstructed breathing during sleep can lead to cardiovascular repercussions. These abnormalities may expose these children to increased anesthetic and surgical risks.

INTRODUCTION. Cardiovascular diseases (CVD) are the main cause of death in Brazil.OBJECTIVE. To evaluate the frequency of CVD risk factors In a population attending a health education community event.METHODS. Retrospective study that included 428 completed forms with clinical and demographic information of volunteers attending a public event, in May, 2006. Data were expressed by means and standard deviation or proportions and compared by Student's t test or Chi-square test. Associations between Arterial Hypertension (AH), Diabetes Mellitus (DM) and clinical variables were analyzed by multinomial logistic regression. Significance level was p<0.05.RESULTS. Mean age was 57 +/- 14years, and women represented 58% of the total population. The main cardiovascular risk factors were AH (39.5%), DM (15.4%) and dyslipidemia (25.89%). The frequency of unawareness about these risk factors was respectively 8.4%, 17.5% and 33.1%.. Family history of CVD was reported by 41% while only 67% reported having any information about DM or dyslipidemia. Among obese individuals (IMC >= 30 Kg/m2, 27.3% of the population), systolic blood pressure (133 +/- 16mmHg), diastolic blood pressure (84 +/- 11.5mmHg) and casual glycemia (124 +/- 52.5mg/dl) were higher when compared to non-obese (p<0.05). There was a significant association between obesity and dyslipidemia (p=0.04). Age and IMC were independently associated with AH and DM.CONCLUSION. The high frequency of modifiable cardiovascular risk factors in this population suggests the need for educational programs to promote primary prevention, mainly for the elderly and overweight.

At present, few data are available on the prevalence and antifungal susceptibility of Candida parapsilosis complex isolates from HIV-infected individuals. The C. parapsilosis complex comprises three species, C. parapsilosis sensu stricto, C. metapsilosis and C. orthopsilosis. Fifteen of 318 Candida isolates were identified as members of the C. parapsilosis complex by PCR and restriction fragment length polymorphism (RFLP). The prevalence of C. parapsilosis complex isolates was 4.7 %, 2.2 % being identified as C. parapsilosis sensu stricto and 2.5% as C. metapsilosis, while no C. orthopsilosis was isolated. This is believed to be the first study that has identified isolates of C. metapsilosis obtained from the oral cavity of HIV-infected individuals. Antifungal susceptibility tests indicated that all the isolates were susceptible to amphotericin B (AMB), fluconazole (FLC), ketoconazole (KTC), itraconazole (ITC), voriconazole (VRC) and caspofungin (CASPO). Although isolates of C. parapsilosis sensu stricto and C. metapsilosis were susceptible to FLC, isolates of C. metapsilosis showed a tendency for higher MICs (>= 1.0 mu g ml(-1)). Based upon the frequency of candidiasis and the fact that certain isolates of the C. parapsilosis complex respond differently to FLC therapy, our data may be of therapeutic relevance with respect to susceptibility and potential resistance to specific antifungal agents. Our data suggest that C. metapsilosis can be a human commensal; its importance as a pathogen has yet to be confirmed.

Este estudo objetivou identificar as representações sociais de agentes comunitários de uma unidade de Programa Saúde da Família sobre o transtorno mental. Optamos pela pesquisa qualitativa, utilizando o estudo de caso. Para a coleta de dados, recorremos à entrevista semi-estruturada, enriquecida pelo uso de Técnica Projetiva, e à análise temática para analisar o material obtido. Os resultados evidenciam representações sociais ancoradas no paradigma psiquiátrico tradicional. Esse considera a pessoa acometida pelo transtorno mental passiva, sem condições de protagonizar os próprios caminhos que, por sua vez, são marcados pelo preconceito. Desse modo, denota-se a grande necessidade de investimento na capacitação em saúde mental, junto aos atores do cenário da assistência do Programa de Saúde da Família. de acordo com o estudo, tal investimento contribuirá para a efetivação de práticas e construção de novos saberes, contribuindo para a melhoria da assistência em saúde.

Objective: To characterize articular and systemic inflammatory activity in juvenile idiopathic arthritis (JIA), identifying remission status with and without medication.Methods: A total of 165 JIA cases, followed for a mean period of 3.6 years, were reviewed in order to characterize episodes of inactivity and clinical remission on and off medication. The resulting data were analyzed by means of descriptive statistics, survival analysis, by comparison of Kaplan-Meier curves, log rank testing and binary logistic regression;analysis in order to identify predictive factors for remission or persistent activity.Results: One hundred and eight of the cases reviewed fulfilled the inclusion criteria: 57 patients (52.7%) exhibited a total of 71 episodes of inactivity, with a mean of 2.9 years per episode; 36 inactivity episodes (50.7%) resulted in clinical remission off medication, 35% of which were of the persistent oligoarticular subtype. The probability of clinical remission on medication over 2 years was 81, 82, 97 and 83% for cases of persistent oligoarticular, extended oligoarticular, polyarticular and systemicJIA, respectively. The probability of clinical remission off medication 5 years after onset of remission was 40 and 67% for patients with persistent oligoarticular and systemic JIA, respectively. Persistent disease activity was significantly associated with the use of an anti-rheumatic drug combination. Age at JIA onset was the only factor that predicted clinical remission (p = 0.002).Conclusions: In this cohort, the probability of JIA progressing to clinical remission was greater for the persistent oligoarticular and systemic subtypes, when compared with polyarticular cases.

O objetivo do presente trabalho foi avaliar os componentes físico-químicos e a produção do leite de búfalas da raça Mediterrâneo criadas no Oeste do Estado de São Paulo. Utilizaram-se 1438 controles provenientes de 152 lactações, controladas no período de 1985 a 1995, na Estação Experimental de Zootecnia de Andradina. Os dados foram analisados por meio do procedimento GLM do Programa SAS. O modelo estatístico para produção de leite teve como fontes de variação (FV) os efeitos fixos de mês do controle e lactação. Para as demais características, usou-se o mesmo modelo, acrescido da produção de leite como covariável. Todas as fontes de variação do modelo foram significativas. As médias ajustadas foram 4,52 kg, 4,13%, 6,59%, 17,01%, 10,47% e 18,98°D, respectivamente, para produção de leite, porcentagens de proteína totais, gordura, extrato seco total, extrato seco desengordurado e acidez. Verificou-se elevado teor de nutrientes no leite, evidenciando a boa qualidade do produto.

Objective: This investigation evaluated the knowledge of dental caries and periodontal disease among removable partial denture (RPD) wearers.Method: A total of 127 partially dentate patients participated in this observational study. A structured questionnaire, which included eight questions referring to knowledge about aetiology and prevention of dental caries and periodontal disease, was developed in the local language (Portuguese) and used to collect the data of all the partial denture wearers. A descriptive analysis of data was performed by means of drafting tables.Results: The results demonstrated that 68.5% of patients interviewed had previously received information about oral health care. With regard to bacterial plaque, it was observed that only 34.6% reported having knowledge of this. Whereas, in relation to caries, 76.4% of the interviewees replied that they knew the meaning of this. Nevertheless, 28.3% referred to caries as a whole in the teeth, 16.5% as bad teeth and 9.4% bacteria/creatures on the teeth. Only 17.3% of the partially edentulous patients evaluated were shown to know what disease of the gingiva was.Conclusion: By means of the methodology applied, it could be concluded that the patients who wore RPDs presented deficient knowledge with regard to the prevention, aetiology and development of dental caries and periodontal disease.
