O treinamento da operação osteoplástica usando o seio frontal do cão

O acesso ao seio frontal usando a técnica do retalho osteoplástico está indicada em lesões que não podem ser abordadas pela via endonasal. O aprendizado da técnica pode ser realizado em cães, mas a delimitação do seio do cão, de forma como se faz no homem, não é facilmente realizável. OBJETIVO: Apresentar um método de localização e delimitação do seio frontal do cão que permita reproduzir a técnica osteoplástica. FORMA DE ESTUDO: Técnica cirúrgica em animal. MATERIAL E MÉTODO: Em cães traçaram-se duas linhas retas, uma delas ao longo da linha média da região frontal, outra passando pela pupila, inclinada 45º em direção à linha anterior. No ponto de intersecção, mede-se um ou um centímetro e meio para frente e um centímetro para trás. A partir destas medidas desenha-se um retângulo incompleto que delineia os limites aproximados do seio frontal. RESULTADOS: O procedimento foi realizado 12 vezes com a participação de médicos residentes. O seio frontal foi aberto facilmente em todos os animais, reproduzindo a técnica osteoplástica sem erros de localização do seio. CONCLUSÃO: O método de localização e de limitação do seio frontal do cão mostrou-se útil no ensino da técnica osteoplástica de acesso por ser reproduzível de forma realística.

Co-inoculation of Rhizobium tropici and Azospirillum brasilense in common beans grown under two irrigation depths

ABSTRACT The alternative technique of co-inoculation or mixed inoculation with symbiotic and non-symbiotic bacteria has been studied in leguminous plants. However, there are few field studies with common beans and under the influence of the amount of irrigated water. Thus, the objective of this study was to evaluate the efficiency of inoculation and co-inoculation of common beans with Rhizobium tropici and Azospirillum brasilense under two irrigation depths. The experiment was carried out in the winter of 2012 and 2013, in Selvíria, state of Mato Grosso do Sul. The experimental design was composed of randomized blocks in split-plot scheme with two irrigation depths in the plots (recommended for common beans and 75% of the recommended) and five forms of nitrogen (N) supply in the split-plots (control non-inoculated with 40 kg ha- 1 of N in topdressing, 80 kg ha- 1 of N in topdressing, A. brasilense inoculation with 40 kg ha-1 of N in topdressing, R. tropici inoculation with 40 kg ha-1 of N in topdressing, and co-inoculation of A. brasilense and R. tropici with 40 kg ha- 1 of N in topdressing) with four repetitions. Co-inoculation increased nodulation in the second year of cultivation. None of the evaluated treatments increased the grain yield in relation to non-inoculated control with 40 kg ha-1 of nitrogen in topdressing, which presented average yield of 2,200 kg ha-1. The use of 75% of the recommended irrigation depth provides similar grain yield to the recommended irrigation depth in common beans cropped in winter.

Accountability and co-production of information and control: social observatories and their relationship with government agencies

Abstract:Through the development of a proposal to categorize accountability into four stages - classical, cross-sectional, systemic, and diffused -, this article aims to identify characteristics of co-production of information and socio-political control of public administration in the work of Brazilian social observatories in relationship with government control agencies. The study analyses data from 20 social observatories and, particularly, three experiences of co-production of information and control, based on a systemic perspective on accountability and a model with four categories: Political and cultural; valuing; systemic-organizational, and production. The conclusions summarize characteristics of these practices, specific phases in the accountability processes, as well as the potentialities and challenges of co-production of information and control, which not only influences, but it is also influenced by the accountability system.

Metodological issues in measuring the detection of emotional disorders by primary care physicians: a review of the literature

A series of studies in the field of Epidemiological Psychiatry have been performed over the last two decades, and these have focused on the ability of primary care physicians to detect emotional disorders in the patients that attend their practices. The scientific methodology utilized in these studies is the subject of this review, which contains a discussion concerning: a) interviewer awareness bias; b) accuracy of the instruments and c) medical and psychological concepts involved in defining minor emotional disorders. Suggestions for change in the methodology are made in each of the sections of the review.

Smoking, consumption of alcohol and sedentary life style in population grouping and their relationships with lipemic disorders

The study, part of the project "Atherosclerotic cardiovascular diseases, lipemic disorders, hypertension, obesity and diabetis mellitus in a population of the metropolitan area of the southeastern region of Brazil", had the following objectives: a) the characterization and distribution among typical human socio-economic groupings, of the prevalence of some particular habits which constitute aspects of life-style-the use of tobacco, the use of alcohol and sedentary activity; b) the establishment of the interrelation between the above-mentioned habits and some lipemic disorders. The prevalence of the habits cited behaved in the following manner: the use of tobacco predominated among men, distributed uniformly throughout the social strata; among the women the average percentage of smokers was 18,9%, a significant difference occurring among the highest socio-economic class, where the average was of 40.2%. The sedentary style of life presented high prevalence, among both men and women with exception of the women of the highest socio-economic level and of the skilled working class. The use of alcohol, as one would expect, is a habit basically practised by the men, without any statistically significant differences between classes. For the purpose of establishing associations between these risk fictors and lipemic conditions four situations were chosen, of the following characteristics: 1- total cholesterol > or = 220 mg/dl and triglycerides > or = 150 mg/dl; 2- HDL cholesterol <35 mg/dl for men and <45 mg/dl for women and triglycerides levels > or = 150 mg/dl; 3- HDL cholesterol <35 mg/dl for men and <45 mg/dl for women and triglycerides levels <150 mg/dl; 4- total cholesterol 220 mg/dl with triglycerides levels <150 mg/dl. Six models of multiple (backward) regression were established, with seven independent variables- age, sex, use of tobacco, consumption of alcohol, light physical activity, hypertension and obesity. Significant associations (P<0,05) were revealed with hypercholesterolemia, accompanied by triglyceride levels > or = 150 mg/dl, and the following independent variables: age, use of tobacco and the interactions between obesity and smoking, age and sedentary lifestyle, sex and obesity (R2=22%); the standardized B coefficient showed that the variables with the greatest weight in the forecasting of the variation in the levels of cholesterol were smoking and the interaction between obesity and smoking. The hypercholesterolemia accompanied by triglycerides levels <150 mg/dl showed a positive association between total cholesterol and sex and the interactions obesity/smoking and sex/obesity. As regards HDL cholesterol accompanied by triglyceride/ levels > or = 150 mg/dl was inversely associated with obesity and the interaction smoking/ age and directly with age (R=31%). The standardized B coeffients, indicated that the variables obesity and the interactions smoking/age possessed a weight three times greater than age alone in accounting for the variation in the serum levels of HDL cholesterol. When accompanied by triglycerides <150 mg/dl there was no association between and the independent variables and the set of them presented R equal to 22%. The sum of top, in the population stutied in this project, the component habits of life-style (smoking, alcohol consumption and sedentary activity) which constitute risk factors which determine morbidity from atherosclerotic cardiovascular diseases are be found distributed through all the typical social groupings of this particular form of social organization. On the other hand, the seven independent variables used in the multiple regression models for the explanation of the lipemic conditions considered presented multiple determination coefficients which varied, approximately, between 20% and 30%. Thus it is important that in the genetic epidemiology the study of the morbidities in question be emphasized.

HIV/tuberculosis co-infection: a request for a better surveillance

The increasing endemicity of tuberculosis resulting from causes such as immigration, poverty, a declining public health infrastructure and co-infection by HIV/Mycobacterium tuberculosis, is leading to a change in tuberculosis control programmes. One of the main reasons for the resurgence of tuberculosis is HIV infection - the risk of tuberculosis is greater in HIV patients than in the majority of the population as can be seen from numerous research projects. The need for systematic testing for HIV infection in all tuberculosis patients by undertaking confidential HIV tests on admission to a tuberculosis programme is brought out. This measure would increase the number of cases diagnosed and provide data for better surveillance of the co-infection.

Transtornos mentais como fatores de risco para o desenvolvimento de abuso/dependência de cocaína: estudo caso-controle

OBJETIVO: Avaliar o papel dos transtornos mentais e da dependência ao álcool como possíveis fatores de risco para o abuso/dependência de cocaína. MÉTODOS: Utilizou-se o desenho caso-controle e a técnica de bola-de-neve (snowball technique) para selecionar uma amostra de usuários de cocaína não tratados na comunidade (casos) e parear casos e controles por sexo, idade e amizade. A coleta de dados foi feita através da utilização do questionário CIDI (Composite International Diagnostic Interview) que gera diagnósticos de acordo com os critérios do Diagnostic and Statistical Manual of Mental Disorders-III-R. A análise dos dados foi feita através de regressão logística condicional. RESULTADOS: O estudo incluiu 208 indivíduos. Os principais resultados mostraram que história passada de dependência ao álcool era o principal fator associado a um aumento no risco de desenvolvimento de abuso de cocaína (OR=15,1; IC 95% 3,8-60,2); nenhum outro transtorno mental isolado manteve-se significativamente associado ao aumento deste risco após a análise multivariada. Aumento no risco de abuso de cocaína também foi encontrado entre os indivíduos que relataram pensamentos suicidas (OR=3,1; IC 95% 0,91-10,8), sugerindo associação entre quadros mais graves de depressão e abuso de cocaína. CONCLUSÕES: Esses achados sugerem que os programas voltados para a prevenção e tratamento do abuso de cocaína devem estar preparados para o manejo de questões relacionadas à co-morbidade do abuso de drogas com o álcool e outros distúrbios psiquiátricos.

Predicting the revolving door phenomenon among patients with schizophrenic, affective disorders and non-organic psychoses

OBJECTIVE: The aim of the study was to identify the variables that predict the revolving door phenomenon in psychiatric hospital at the moment of a second admission. METHODS: The sample consisted of 3,093 patients who have been followed during 5 to 24 years after their first hospital admission due to schizophrenia, and affective or psychotic disorders. Those who had had four or more admissions during the study period were considered as revolving door patients. Logistic regression analyses were used to assess the impact of gender, age, marital status, urban conditions, diagnosis, mean period of stay on the first admission, interval between the first and second admissions on the patterns of hospitalization. RESULTS: The variables with the highest predictive power for readmission were the interval between first and second admissions, and the length of stay in the first admission. CONCLUSIONS: These data may help public health planners in providing optimal care to a small group of patients with more effective utilization of the available services.

Distribuição espacial da co-infecção M. tuberculosis/HIV no Estado de São Paulo, 1991-2001

OBJETIVO: Avaliar o padrão espacial de incidência de tuberculose na epidemia de Aids, a fim de verificar a influência do espaço físico na causalidade. MÉTODOS: Foram incluídos os casos de Aids notificados ao Ministério da Saúde, entre 1991 e 2001, provenientes do Estado de São Paulo. Os casos foram estratificados em municípios de residência, em regiões de saúde, em categorias de transmissão de Aids, em sexos e em anos do diagnóstico. Um modelo geoestatístico gaussiano foi usado para construir um mapa temático de risco, utilizando a incidência de tuberculose em casos de Aids como variável de resposta. RESULTADOS: A análise exploratória mostrou dois padrões de incidência de Aids: um, para a capital do Estado, e outro, com risco crescente, para os outros municípios. As regiões mais populosas estão sob maiores riscos de transmissão de tuberculose, mostrando um padrão concordante com o padrão de ocupação do território, do leste para o oeste. As regiões de saúde com os maiores coeficientes de incidência de Aids (por 10 mil habitantes) foram Santos (53,5), São José do Rio Preto (43,1), Ribeirão Preto (42,4) e São Paulo (40,3). As regiões de saúde com maiores incidências de tuberculose em casos de Aids foram Santos (44,9%), Franco da Rocha (39,9%), Osasco (39,6%) e São Paulo (38,9%). CONCLUSÕES: Os resultados permitem concluir que as coordenadas geográficas estão associadas ao risco da tuberculose, mas não de Aids.

Co-ocorrência de violência física conjugal e contra filhos em serviços de saúde

OBJETIVO: Apresentar um perfil de ocorrência e co-ocorrência de violência física conjugal e contra filhos em uma população atendida em serviço de saúde, segundo diferentes características socioeconômicas e demográficas. MÉTODOS: Estudo transversal sobre violência familiar e prematuridade, realizado na cidade do Rio de Janeiro, em 2000. Foram elegíveis para a análise os domicílios contendo mulheres vivendo com companheiro e nos quais coabitavam com pelo menos um filho (ou enteado) de até 18 anos (n=205). Condições socioeconômicas, demográficas e relativas aos hábitos de vida da mulher e do companheiro foram consideradas como potenciais preditores de violência. A variável de desfecho foi analisada em quatro níveis: ausência de violência física no domicílio; ocorrência de violência física no casal; contra pelo menos um filho; e coocorrência. Utilizou-se um modelo logito-multinomial para as projeções de prevalências desses matizes de violência segundo os descritores selecionados. RESULTADOS: Os fatores associados ao maior risco do desfecho foram: idade materna >25 anos; companheiro com primeiro grau incompleto, presença de >2 crianças menores de cinco anos no domicílio; e abuso de álcool e drogas ilícitas pelo companheiro. Em domicílios com todas essas características, a estimativa conjunta de prevalência projetada de violência no casal e contra filhos chegou a 90,2%, sendo de 60,6% a de coocorrência. Na ausência desses fatores, as estimativas foram consideravelmente menores (18,9% e 0,2%, respectivamente). CONCLUSÕES: Profissionais de saúde não devem somente atentar à presença de um gradiente situacional, mas também ao fato de que existe paulatinamente mais chance dos agravos violentos acontecerem como um fenômeno englobando todo o grupo familiar.

Clinical and functional aspects of work-related musculoskeletal disorders among active workers

OBJECTIVE: To evaluate musculoskeletal disorders among active industrial workers. METHODS: The study was carried out in São Carlos, Southeastern Brazil, in 2005. One hundred and thirty-four female workers were physically evaluated and answered questions about their physical symptoms, filled out a pain scale and gave responses in the Oswestry Disability Questionnaire, and the Work Ability Index questionnaire. The data were analyzed descriptively, and in correlation tests and through applying logistic regression. The outcome was evaluated in relation to the perceptions of pain, symptoms, physical assessment, ability to work and disability. RESULTS: Clinical evaluations and sick leave presented positive correlations with the subjective variables. The Work Ability Index presented a negative correlation with the physical disability index (r=-0.69). Symptoms reported at the time of the assessment presented a good correlation with the results from the pain scale and the clinical findings. Previous sick leave showed an association with disability (OR=1.13; 95% CI:1.08;1.18). CONCLUSION: Symptom reports and pain scales may be useful for assessing current conditions at the time of evaluating individuals with work-related musculoskeletal disorders, as they are easier to apply. In more severe cases of such injuries, clinical and functional evaluations and questionnaires such as those relating to ability to work and disability are preferable. Precise and specific evaluations of these disorders may contribute towards fairer legal and administrative decisions.
