OBJETIVO: Estudar a ocorrência dos erros refracionais em escolares de nosso meio. MÉTODOS: Estudo transversal avaliando crianças da pré-escola e do ensino básico, quanto ao sexo, tipo de erro refracional, acuidade visual e tratamento realizado. RESULTADOS: Quatro mil seiscentos e vinte e três crianças foram submetidas a exame de acuidade visual, das quais 8,1% apresentaram necessidade de exame oftalmológico completo. Houve 63,2% de portadores de astigmatismo hipermetrópico, 15,7% de astigmatismo miópico, 12,5% de astigmatismo misto, 4,9% de hipermetropia e 3,7% de miopia. Foi indicada a prescrição de lentes corretoras para 48,7% da amostra estudada. A frequência de erros refracionais na população foi de 3,9%. CONCLUSÃO: O astigmatismo hipermetrópico foi o erro de refracional mais frequente, havendo necessidade de tratamento em cerca de 50% das crianças triadas com frequência de 3,9% de erro refracional passível de correção na população de estudo.

OBJETIVOS: Estabelecer a freqüência de erros inatos do metabolismo (EIMs) em uma amostra de pacientes com hipótese diagnóstica de EIM proveniente do Hospital das Clínicas da Faculdade de Medicina de Botucatu da Universidade Estadual Paulista (UNESP) e analisar a metodologia empregada nessa investigação. AMOSTRA E MÉTODOS: Foram triadas para EIM, por testes químicos e técnicas cromatográficas, 1.233 amostras de urina de 905 pacientes. RESULTADOS: O diagnóstico de EIM foi estabelecido em 18 (1,98%) pacientes; 12 deles apresentaram triagem (testes químicos e cromatografias) alterada para EIM. Todos os pacientes foram diagnosticados por análises enzimáticas. CONCLUSÃO: A freqüência de EIMs diagnosticados neste estudo (1,98%), quando comparada com a literatura, foi satisfatória, uma vez que este grupo de pacientes foi proveniente de um único hospital. A metodologia provou ser eficaz, indicando 12 casos de EIM entre os 18 diagnosticados. O estudo mostra a importância de laboratórios especializados na detecção deste tipo de patologia.

The aim of this study was to verify the adherence of participants in a program of physical activity; and to verify if there is any association between the age, Body Mass Index and General Functional Fitness Index with this adherence. It was used the control of frequency for 62 months and data of the anthropometric and functional evaluations of 122 participants (58 + 9 years). 49.2% of the participants gave the program up and 50.8% remained to it. The average of permanence time was 24 + 17 months. The percentage of the adherence of people with satisfactory fitness is greater than with not satisfactory fitness. The percentage of adherence of older people is larger than younger age. The percentage of adherence of not-obese is greater than of obese. However, none of these variables presented statistical difference. It can be concluded that even though there was adherence with similar results even to permanence as to desistance, the time of permanence in the program was very high when compared to other studies.

Atendeu-se uma cadela, sem raça definida, com aproximadamente cinco meses de idade, apresentando anamnese com queixa de apatia e hiporexia associadas a vômitos e emagrecimento progressivo com início incerto. Ao exame físico era evidente distensão abdominal com dilatação intestinal e aumento de peristaltismo. O animal apresentava-se emaciado e subdesenvolvido, com acentuado grau de desidratação, pulso filiforme e nível de consciência reduzido. Minutos após o início do atendimento a cadela foi a óbito. À necropsia, pôde-se observar um segmento do intestino delgado atravessando o púbis e com lúmen reduzido. Tal apresentação se faz relevante por se tratar de um caso nunca antes descrito na literatura veterinária.

In recent work (Kroll, 1990) on dairy cattle growth using its monthly weights, a Gompertz function, first considering the autocorrelated error structure, and second, the independent error structure, was fitted. The last explained 25% more of the total variance than the former. In this work, a Gompertz function was fitted with autocorrelated error structure adding seasonality to the model. This was suggested taking into account the time series autocorrelation function. In order to estimate the six parameters, an iterative procedure was used, employing a matrix X = [G\S], where G is the usual matrix for fitting the Gompertz function, and S is a 0s, 1s, -1s matrix necessary to take into account seasonality. With this model, the adjustment was better in terms of the coefficient determination.

Cara inchada of cattle (CI) is a periodontitis which occurs in calves in several regions of Brazil. Its progressive lesions, caused mainly by Bacteroides melaninogenicus and Actinomyces pyogenes, could lead to loss of teeth, malnutrition and possibly death of affected animals. For further analysis of the pathogenesis of this disease the influence of streptomycin on the adherence of the causative bacteria to oral epithelial cells of cattle was determined. Production of streptomycin by soil bacteria (Actinomycetes) in Brazil had been suggested by several authors. In our studies, streptomycin in subinibitory concentrations increased tenfold the rate of adherence with B. melaninogenicus (from 0.4 to 4.0 bacteria per bovine epithelial cell). On the contrary, streptomycin did not influence significantly the adherence of A. pyogenes nor streptococci of the viridans group. Thus, streptomycin could be a contributing factor to the development of the periodontal infections with B. melaninogenicus.

This article has the purpose to review the main codes used to detect and correct errors in data communication specifically in the computer's network. The Hamming's code and the Ciclic Redundancy Code (CRC) are presented as the focus of this article as well as CRC hardware implementation. Each code is reviewed in details in order to fill the gaps in the literature and to make it accessible to the computer science and engineering students as well as to anyone who may be interested in learning the technique to treat error in data communication.

The polyethylene terephthalate (PET) is used for package drugs and cosmetics. The aim of this research was examine by scanning electron microscopy (SEM) a Staphylococcus aureus attachment and biofilm formation on a polyethylene terephthalate (PET) surface and hydrophobicity of S. aureus by adherence to hydrocarbons. A suspension of S. aureus was prepared in Mueller-Hinton broth and, coupons of polyethylene terephthalate were incubated for 30 minutes, two, 24 and 48 hours, 15 and 30 days. Afteron the coupons were removed and prepared for scanning electron microscope analysis. The attachment and biofilm formation was observed on the surfaces of PET. The SEM revealed adhesion and biofilm formation on PET surfaces. The hydrophobicity test classified S. aureus as hydrophobic.

This article reviews the metabolism of fructose and sorbitol, their main clinical indications and the consequences of inadequate use. Fructose, an important carbohydrate in the diet, is present mostly in fruits and vegetables; it can also be synthesized from glucose in the organism, through the sorbitol. Fructose is known for its metabolism's inherent errors, whose clinical manifestations are potentially serious, as well as for its use as a glucose substitute in the diabetic patients' diet, due to its metabolism not being dependent from insulin. In the last years, especially in developed countries, the consumption of fructose has increased considerably, due to its use as a sweetener in industrialized foods. However, adverse side-effects may occur with the excessive ingestion of fructose, such as the increase in blood's triglycerides and cholesterol. Therefore, to know which are the patients' normal blood levels is quite important for establishing the safe amount of fructose to be prescribed, as well as for allowing the screening of metabolism diseases associated with fructose.
