[factors Impacting The Growth And Nutritional Status Of Cystic Fibrosis Patients Younger Than 10 Years Of Age Who Did Not Undergo Neonatal Screening.]

The aim of this study was to evaluate by clinical and laboratory parameters how cystic fibrosis (CF) affects growth and nutritional status of children who were undergoing CF treatment but did not receive newborn screening. A historical cohort study of 52 CF patients younger than 10 years of age were followed in a reference center in Campinas, Southeast Brazil. Anthropometric measurements were abstracted from medical records until March/2010, when neonatal screening program was implemented. Between September/2009 and March/2010, parental height of the 52 CF patients were also measured. Regarding nutritional status, four patients had Z-scores ≤ -2 for height/age (H/A) and body mass index/age (BMI/A). The following variables were associated with improved H/A ratio: fewer hospitalizations, longer time from first appointment to diagnosis, longer time from birth to diagnosis and later onset of respiratory disease. Forced vital capacity [FVC(%)], forced expiratory flow between 25-75% of FVC [FEF25-75(%)], forced expiratory volume in the first second [FEV1(%)], gestational age, birth weight and early respiratory symptoms were associated with IMC/A. Greater number of hospitalizations, diagnosis delay and early onset of respiratory disease had a negative impact on growth. Lower spirometric values, lower gestational age, lower birth weight, and early onset of respiratory symptoms had negative impact on nutritional status. Malnutrition was observed in 7.7% of cases, but 23% of children had nutritional risk.

Listas de alimentos relacionadas ao consumo alimentar de um grupo de idosos: análises e perspectivas

INTRODUÇÃO: A despeito do aumento expressivo da população idosa nos últimos anos, são escassos os estudos brasileiros relacionados ao consumo alimentar desses indivíduos. OBJETIVOS: Propor uma lista de alimentos mais consumidos por idosos residentes na Zona Leste de São Paulo e analisar os alimentos que contribuem para o consumo de nutrientes relevantes ao estado nutricional e, consequentemente, à saúde dos idosos. MÉTODOS: Foram avaliados 100 indivíduos acima de 60 anos, frequentadores de um centro de referência. Para caracterização do estado nutricional foi calculado o Índice de Massa Corporal (IMC). Para elaboração das listas de alimentos foram aplicados dois recordatórios alimentares de 24 horas (RA24h) em duas estações diferentes do ano, que foram analisados quanto à frequência de consumo de cada alimento e quanto à contribuição percentual de energia, macronutrientes, fibras, cálcio e vitamina D. RESULTADOS: Com relação ao estado nutricional, 52% apresentaram o IMC < 28 kg/m²; 15% entre 28 e 30 kg/m²; 26% entre 30 e 35 kg/m² e 7% com IMC > 35 kg/m². O aspecto positivo da dieta foi a preservação de hábitos saudáveis como o consumo de arroz e feijão, e também de vegetais verde-escuros. Como aspecto negativo observou-se que a dieta dos idosos é monótona, pois poucos alimentos contribuem para o consumo de vários nutrientes. Além disso, houve um elevado consumo de carboidratos refinados em detrimento do consumo de alimentos integrais. CONCLUSÕES: As listas de alimentos obtidas, além de permitirem a reflexão sobre intervenções educativas, permitem o desenvolvimento subsequente de um Questionário de Frequência Alimentar específico para esse grupo.

A Classificação Internacional de Funcionalidade, Incapacidade e Saúde e a AIDS: uma proposta de core set

O advento da terapia anti-retroviral de alta potência (HAART) alterou a história natural da aids, diminuindo sua mortalidade e a incidência de doenças oportunistas e aumentando a esperança de vida das pessoas vivendo com aids.Como uma doença crônica, outras questões passam a ser relevantes, entre elas a adesão ao tratamento, seus efeitos adversos e a qualidade de vida das pessoas nessa condição. A CIF constitui um instrumento adequado para identificar as características da funcionalidade, do ambiente e condições pessoais que interferem na qualidade de vida. Instrumentos para a sua aplicação, core sets, têm sido desenvolvidos para várias condições de saúde. Com o objetivo de propor um core set para aids, foram desenvolvidas duas etapas preliminares do modelo proposto para a construção desses instrumentos. A primeira etapa, de revisão sistemática buscou no MEDLINE artigos com descritores HAART e qualidade de vida, publicados em inglês, de 2000 a 2004. Foram selecionados 31 estudos que resultou em 87 conceitos dos quais 66 puderam ser identificados como categorias da CIF. Estas formaram as perguntas da entrevista aplicada em 42 voluntários, pacientes de um centro de referência para DST e Aids de São Paulo. Entre as condições mais freqüentemente associadas ao tratamento, estão às mudanças na imagem corporal, conseqüência da lipodistrofia, apontada em 84 por cento dos estudos e em 93 por cento das entrevistas. Alterações das funções digestivas, das relações íntimas, e das funções sexuais foram condições importantes identificadas no estudo. As duas etapas definiram 40 categorias da CIF como proposta preliminar de um core set para pacientes com aids

Tuberculosis among health care workers in a Brazilian tertiary hospital emergency unit

The Brazilian emergency system is being reorganized as a hierarchy in the region of Ribeirao Preto, state of Sao Paulo. We found increased occupational risk for tuberculosis in this region tertiary reference center-a nurse technician (Incidence rate [IR] 526.3/100000 inhabitants) had a risk of tuberculosis 12.6 (95% confidence interval [CI], 2.57-37.23) greater than the city population (41.8/100000 inhabitants). The system reorganization will have to make the centers adequate to deal with this problem. (C) 2008 Elsevier Inc. All rights reserved.

A formação pela trilha da clínica da atividade na vigilância em saúde do trabalhador

Trata-se de uma pesquisa-intervenção com o objetivo principal de colocar em análise a atividade na vigilância em saúde do trabalhador ancorada nos pressupostos da formação pelo trabalho. Tem como aporte conceitual o referencial teórico-metodológico da clínica da atividade proposta por Yves Clot e colaboradores. A pesquisa foi realizada com a equipe multiprofissional que atua na vigilância em saúde do trabalhador do Centro de Referência Estadual em Saúde do Trabalhador do Espírito Santo (Cerest/ES). As rodas de conversa, a partir da clínica da atividade, foram a estratégia metodológica privilegiada. O gênero profissional vigilante em saúde do trabalhador, ao se confrontar com o estudo das diretrizes da clínica da atividade, foi produzindo deslocamentos que o levou a (re)pensar, analisar a sua atividade e o processo de trabalho no qual estava inserido. A cada encontro no diálogo com a clínica da atividade, eram experimentados os modos de como esses profissionais atuavam na vigilância, como também todo o atravessamento desse gênero na assistência aos trabalhadores, nas atividades educativas e gestão do trabalho. No desenvolvimento das rodas, ficou evidenciado o quanto esses encontros se tornaram equipamentos para esses profissionais. As atividades desenvolvidas produziram análise coletiva do trabalho e um processo de formação pelo trabalho. Buscaram incorporar os métodos utilizados pela clínica da atividade no cotidiano do Cerest dialogando com os efeitos desse processo. Nas rodas também emergiram propostas de mudanças na maneira como vinham ocorrendo as atividades realizadas, a gestão do trabalho nessa equipe e as estratégias de atuação na vigilância, ou seja, intervenção no processo de trabalho do grupo, produzindo potência para o poder de agir do gênero. O referencial teórico-metodológico da clínica da atividade foi um dispositivo de formação importante. Permitiu a experimentação e o desenvolvimento do gênero vigilantes em saúde do trabalhador na produção de análise da atividade, na constituição de uma clínica dialógica em transformação. Também possibilitou contemplar na análise as dimensões integrantes da atividade de trabalho, fazendo a interlocução para o encontro entre os saberes da experiência instituídos no cotidiano do serviço de saúde e o saber acadêmico na produção de conhecimento.

Epidemiological aspects of centipede (Scolopendromorphae: Chilopoda) bites registered in Greater S. Paulo, SP, Brazil

INTRODUCTION: The lack of basic knowledge on venomous arthropods and the benignity of the clinical manifestations contribute to the centipede bite victims' not being taken to a treatment reference center, leading to underestimation of the number of cases and minimizing the possibility of a broader epidemiological view. An inventory of the centipede bite occurrences in Greater S. Paulo, Brazil, and the therapeutic methods employed, by the main Brazilian medical center for the notification of poisoning by venomous animals, is presented. METHOD: All patient cards of the period 1980-1989 have been checked as to place, month and time of occurrence; sex, age, affected part of the body, signs and symptoms have been observed, as well as the therapeutic methods employed. The centipedes that caused the accidents were identified at the Arthropods Laboratory. RESULTS: It was registered 216 accidents, with a 69% predominance of the Greater S. Paulo and in only 63% of the cases (136) was the agent brought in by the victim for identification. The genera most frequently represented were Cryptops (58%), Otostigmus (33%) and Scolopendra (4%). Of the 136 cases, 87% showed erythema, edema, hemorrhage, burns, cephalalgia, and intense pain. There was a predominance of accidents in the warm rainy season, in the morning and for females between 21 and 60 years of age. Hands and feet were the parts of the body most affected. The benign evolution of the clinical picture (54%) made therapeutical treatment unnecessary. Only the victims of Scolopendra and Otostigmus (46%) were medicated with anesthetics (51%), analgesics (25%), antihistamines and cortisone (24%). CONCLUSION: The reproductive period of the centipedes, associated with their sinanthropic habits, contributes to the greater incidence of accidents in urban areas in the warm rainy season. Only patients bitten by Scolopendra and Otostigmus require therapeutical treatment.

Mammography in asymptomatic women aged 40-49 years

OBJECTIVE To assess findings of mammography of and interventions resulting from breast cancer screening in women aged 40-49 years with no increased risk (typical risk) of breast cancer. METHODS This cross-sectional study evaluated women aged 40-49 years who underwent mammography screening in a mastology reference center in Recife, PE, Northeastern Brazil, between January 2010 and October 2011. Women with breast-related complaints, positive findings in the physical examination, or high risk of breast cancer were excluded. RESULTS The 1,000 mammograms performed were classified into the following Breast Imaging-Reporting and Data System (BI-RADS) categories BI-RADS 0, 232; BI-RADS 1, 294; BI-RADS 2, 294; BI-RADS 3, 16; BI-RADS 4A, 2; BI-RADS 5, 1. There was one case of grade II invasive ductal carcinoma and various interventions, including 469 ultrasound scans, 53 referrals to mastologists, 11 cytological examinations, and 8 biopsies. CONCLUSIONS Mammography screening in women aged 40-49 years with typical risk of breast cancer led to the performance of other interventions. However, it also resulted in increased costs without demonstrable efficacy in decreasing mortality.

Sorotipos de Streptococcus pneumoniae isolados de líquido cefalorraquidiano no período de 1977-1988 na cidade de São Paulo, Brasil

Desde 1977, o Instituto Adolfo Lutz (IAL) vem promovendo a sorotipagem do S. pneumoniae ou pneumococo de infecções causadas por esta bacteria. As cepas isoladas têm sido encaminhadas ao WHO Pneumococcal Reference Center, Pensilvania, E.U.A.. De 1977 a 1988, 1.000 cepas de pneumococo isoladas de LCR foram sorotipadas, de acordo com a nomenclatura dinamarquesa, e 60 sorotipos foram identificados. A maior freqüência foi do sorotipo 1, secundado por 6B, 18C, 14, 5, 3, 6A, 23F, 19F e 38. Estes sorotipos distribuídos segundo faixas etárias demonstraram incidência variável, notando-se uma certa peculiaridade, ou seja, a predominância do sorotipo 6B na faixa de zero a menos de dois anos; do sorotipo 1 na faixa de 2 até 50 anos e do sorotipo 3 no grupo acima de 50 anos. Nos 12 anos considerados, 25 sorotipos apresentaram uma certa uniformidade na freqüência e o mesmo foi observado com relação às estações climáticas, apenas com um número maior de infecções meníngeas nos meses mais frios. Considerando a gravidade das infecções pneumocócicas notadamente as meningites, e a pouca informação relativa aos sorotipos pneumocócicos que ocorrem na região, julgamos importante essa informação relativa aos sorotipos, uma vez que tem sido usadas, com sucesso, vacinas polissacarídicas na prevenção dessas infecções.

Seasonal variation of hepatitis A virus infection in the city of Rio de Janeiro, Brazil

Hepatitis A virus (HAV) infection constitutes a major public health problem in Brazil. The transmission of HAV is primarily by fecal-oral route so the water is an important vehicle of HAV dissemination. There is a great incidence of acute cases of hepatitis A in some areas of Brazil however the seasonal variation of these cases was not documented. The aim of this study was to determine the seasonality of HAV infection in Rio de Janeiro. From January 1999 to December 2001, 1731 blood samples were collected at the National Reference Center for Hepatitis Viruses in Brazil (NRCHV). These samples were tested by a commercial enzyme-immunoassay to detect anti-HAV IgM antibodies. Yearly positive rates were 33.74% in 1999, 32.19% in 2000, and 30.63% in 2001. A seasonal variation was recognized with the highest incidence in spring and summer. Furthermore a seasonal increase in incidence of HAV infection was found during the rainy season (December to March) because the index of rains is very high. It is concluded that HAV infections occur all year round with a peak during hot seasons with great number of rains.

Encerramento Percutâneo de Shunts Interauriculares: Experiência de uma Década de um Centro Terciário

INTRODUCTION: Atrial septal defects (ASD) are among the most common congenital anomalies and account for 10% of congenital heart disease in the pediatric age-group and 30% in adults. Closure is indicated when there is evidence of hemodynamic significance or after a paradoxical embolic event. Ten years ago, percutaneous closure became the treatment of choice in our center for all patients with a clear indication and favorable anatomy. In this paper we report the experience of this first decade. OBJECTIVE: To assess the short- and long-term results of our ten-year experience with percutaneous closure of atrial septal defects. METHODS: We studied retrospectively all patients with ASD treated with a percutaneous approach between November 1998 and December 2008. The pediatric age-group consisted of patients younger than 19 years old. Demographic data, clinical indications, minor and major complication rates, success rate and long-term outcome were assessed. RESULTS: In the first ten years of experience 510 patients, of whom 166 were in the pediatric group, were treated in our center by a team of adult and pediatric cardiologists. The overall success rate of the procedure was 98% (97.5% in ASD and 99.5% in patent foramen ovale (PFO). The minor complication rate was 3% (3.4% in ASD and 2% in PFO). The most frequent complication was supraventricular tachycardia. The major complication rate was 1.2% (0.6% in ASD and 2% in PFO). Two patients developed cardiac tamponade due to hemopericardium that was resolved by pericardiocentesis, without need for surgery. One patient had an arterial pseudoaneurysm corrected by vascular surgery. There was no device embolization and no need for urgent surgery in this population. During follow-up two patients had recurrence of ischemic stroke, one had a transient ischemic attack and another had a hemorrhagic stroke. Mortality was 0.6% (0.6% in ASD and 0.5% in PFO). There were no in-hospital deaths. During follow-up there were two deaths, both in the adult group. DISCUSSION AND CONCLUSION: In this population the success rate was high and most of the complications were minor. The results of this collaboration between adult and pediatric cardiologists in the first ten years of activity confirm the safety and efficacy of percutaneous closure of septal defects, when there is careful patient selection and a standardized technique.

Resultados da Angioplastia Primária num Centro de Referência. Evolução Intra-Hospitalar

INTRODUCTION: Primary angioplasty is accepted as the preferred treatment for acute myocardial infarction in the first 12 hours. However, outcomes depend to a large extent on the volume of activity and experience of the center. Continuous monitoring of methods and results obtained is therefore crucial to quality control. OBJECTIVE: To describe the demographic, clinical and angiographic characteristics as well as in-hospital outcomes of patients undergoing primary PCI in a high-volume Portuguese center. We also aimed to identify variables associated with in-hospital mortality in this population. METHODS: This was a retrospective registry of consecutive primary PCIs performed at Santa Marta Hospital between January 2001 and August 2007. Demographic, clinical, and angiographic characteristics and in-hospital outcomes were analyzed. Independent predictors of in-hospital mortality were identified by multivariate logistic regression analysis. RESULTS: A total of 1157 patients were identified, mean age 61+/-12 years, 76% male. Mean pain-to-balloon time was 7.6 hours and primary angiographic success was 88%. Overall in-hospital mortality was 6.9%, or 5.5% if patients presenting in cardiogenic shock were excluded from the analysis. Previous history of heart failure, cardiogenic shock on admission, invasive ventilatory support, major hemorrhage, and age over 75 years were found to be associated with increased risk of in-hospital death. Conclusions: In this center primary PCI is effective and safe. Angiographic success rates and in-hospital mortality and morbidity are similar to other international registries. Patients at increased risk for adverse outcome can be identified by simple clinical characteristics such as advanced age, cardiogenic shock on admission, mechanical ventilation and major hemorrhage during hospitalization.

HTLV- I infection is not associated with a higher risk of death in peruvian HIV-infected patients

Limited and contradictory information exists regarding the prognosis of HIV/HTLV-I co-infection. Our goal was to estimate the effect of HTLV-I infection on mortality in HIV-infected patients at a HIV reference center in Peru. We studied a retrospective cohort of HIV-infected patients, who were exposed or unexposed to HTLV-I. Exposed patients were Western Blot (WB) positive for both retroviruses. Unexposed patients were WB positive for HIV, and had least one negative EIA for HTLV-I. These were selected among patients who entered our Program immediately before and after each exposed patient, between January 1990 and June 2004. Survival time was considered between the diagnosis of exposure to HTLV-I and death or censoring. Confounding variables were age, gender, baseline HIV clinical stage, baseline CD4+ T cell count, and antiretroviral therapy. We studied 50 exposed, and 100 unexposed patients. Exposed patients had a shorter survival compared to unexposed patients [median survival: 47 months (95% CI: 17-77) vs. 85 months (95% CI: 70-100), unadjusted p = 0.06]. Exposed patients had a higher rate of mortality compared to unexposed patients (HIV/HTLV-I (24/50 [48%]) vs. HIV only (37/100 [37%]), univariable p = 0.2]. HTLV-I exposure was not associated to a higher risk of death in the adjusted analysis: HR: 1.2 (0.4-3.5). AIDS clinical stage and lack of antiretroviral therapy were associated to a higher risk of dying. In conclusions, HTLV-I infection was not associated with a higher risk of death in Peruvian HIV-infected patients. Advanced HIV infection and lack of antiretroviral therapy may explain the excess of mortality in this population.

Co-infection of Dengue virus by serotypes 3 and 4 in patients from Amazonas, Brazil

The natural co-infection with dengue virus can occur in highly endemic areas where different serotypes have been observed for many years. We report here four cases of DENV-3/DENV-4 co-infection detected by serological and molecular tests among 674 patients with acute undifferentiated fever from the tropical medicine reference center of Manaus City, Brazil, between 2005 and 2010. Analysis of the sequences obtained indicated the presence of genotype 3 and 1 for DENV-3 and DENV-4 respectively.
