Prática de vacinação em crianças com doenças reumáticas

INTRODUÇÃO/OBJETIVOS: Avaliar a prática clínica com relação à verificação do cartão vacinal e à indicação de vacinas específicas em pacientes com doenças reumáticas pediátricas em uso de diferentes drogas, e evidenciar a possível associação entre frequência de vacinação e tempo de prática clínica dos reumatologistas pediátricos do estado de São Paulo. MATERIAL E MÉTODOS: Um questionário foi enviado para os reumatologistas pediátricos do Departamento de Reumatologia da Sociedade de Pediatra de São Paulo. Esse instrumento incluiu questões sobre tempo de prática em Reumatologia Pediátrica, vacinação de pacientes com Lúpus Eritematoso Sistêmico Juvenil (LESJ), artrite idiopática juvenil (AIJ), dermatomiosite juvenil (DMJ) e imunização de acordo com os tratamentos utilizados. RESULTADOS: Cartão de vacinação foi visto por 100% dos profissionais na primeira consulta e por 36% anualmente. Vacinas de agentes vivos não foram recomendadas para pacientes com LESJ, AIJ e DMJ em 44%, 64% e 48%, respectivamente. Os profissionais foram divididos em dois grupos: A (< 15 anos de prática, n = 12) e B (> 16 anos, n = 13). Nenhuma diferença estatística foi observada no uso de vacinas de agentes vivos e vacinas de agentes inativos ou componentes proteicos em relação ao tratamento nos dois grupos (P > 0,05). Além disso, os grupos foram similares em relação à opinião sobre a gravidade de imunossupressão em pacientes com LESJ, AIJ e DMJ com ou sem atividade e a terapêutica utilizada (P > 0,05). CONCLUSÕES: A frequência de vacinação por reumatologistas pediátricos de São Paulo é baixa, especialmente após a primeira consulta, e não é influenciada pelo tempo de prática profissional.

Prevalência de fatores de risco para doenças cardiovasculares entre escolares em Londrina - PR: diferenças entre classes econômicas

OBJETIVO: Avaliar e comparar a prevalência de fatores de riscos cardiovasculares em adolescentes escolares de diferentes classes econômicas. MÉTODOS: Foram avaliados 1.021 adolescentes. Os indivíduos foram pesados e tiveram sua altura e circunferência abdominal medidos, além da sua pressão arterial aferida. A prática de atividade física e condição socioeconômica foram relatadas. Os resultados foram avaliados pela utilização da frequência das variáveis e pelo teste do qui-quadrado. RESULTADOS: Observou-se menor prevalência de sedentarismo (p < 0,001) e maiores prevalências de obesidade abdominal (p = 0,038) e de sobrepeso (p = 0,010) entre adolescentes da classe econômica alta. Não houve diferença de prevalência de pressão arterial elevada entre adolescentes da classe econômica baixa e alta. Quando os fatores de risco cardiovasculares foram agregados, a prevalência também foi maior na classe econômica alta para um ou dois fatores de risco. CONCLUSÃO: Com exceção do sedentarismo e da pressão arterial elevada, a prevalência de fatores de risco para doenças cardiovasculares foi maior na classe econômica alta.

Complicações psiquiátricas do uso crônico do álcool: síndrome de abstinência e outras doenças psiquiátricas

A síndrome de abstinência alcoólica é um quadro agudo, caracterizado por um conjunto de sinais e sintomas autolimitados, com gravidade variada, secundário à interrupção total ou parcial do consumo de álcool, podendo ser associado a inúmeros problemas clínicos e/ou outros transtornos psiquiátricos. O objetivo deste artigo é rever as principais complicações psiquiátricas secundárias à síndrome de abstinência alcoólica, como convulsões e delirium tremens, bem como algumas outras condições psiquiátricas associadas à dependência de álcool, como as síndromes de Wernicke Korsakoff e de Marchiava Bignami. Pretende-se, com isso, auxiliar no diagnóstico precoce e tratamento adequado, minimizando assim a morbidade e a mortalidade associadas a tais complicações.

Doenças respiratórias em aves atendidas no laboratório de oriento- Patologia da FMVZ-UNESP/Botucatu-SP, Brasil, nos anos de 2005 A 2006

The respiratory tract of birds shows anatomical and physiological characteristics that facilitates the occurrence of disease, mainly those of microbiological origin. This article analyzes the frequency of respiratory diseases in domestic and wild birds treated during the years 2005-2006 at the Ornitopathology Laboratory of the Veterinary Hospital, Faculty of Veterinary Medicine and Zootecnics, São Paulo State University (FMVZUNESP). Diagnoses were obtained through clinical and radiographic exams as well as haemogram, microbiological culture, parasitological tests and necropsy, being septicemic processes, aspergillosis and mycoplasmosis the most diagnosed diseases. No zoonotic threats were identified, so the entities were described as of low-impact on public health. However, the above mentioned agents can provoke death of birds and difficult for treating and eradication as well.

O sistema imune dos insetos e o controle de algumas doenças parasitárias humanas

Parasitic diseases in humans, transmitted by insects, affect about 500 million people living mainly in countries of low economic power. The control of these diseases is difficult to carry out, mianly due to social and political problems, enhanced by the capacity of these organisms to develop resistance to insecticides used to for their destruction. Some recent advances in the area of insect immunology have open the possibility for abetter epidemiological control of these diseases. The immune system of these insects, as well as that of other organisms, have the ability to recognize the infecting parasites and liberate a series of reactions which stop the infection. These reactions involve the circulating cells (hemocytes) against the parasite. These cells have the ability of phagocytize and liberate the production of various humoral factors, neutralizing the infection. Some promising results, obtained by the study of the immune system of malaria-transmitting insects, the sleeping disease, and dengue, are an example of this new sanitary strategy.

Espectro de agentes etiológicos associados a surtos de doenças transmitidas por alimentos em núcleos receptores turísticos de três regiões geográficas do Estado de São Paulo

Foodborne and waterborne diseases are spread by the consumption of food or water contaminated with bacteria and/or their toxins, viruses, parasites or chemicals. The aim of the research reported here was to establish the spectrum of etiologic agents of foodborne outbreaks at 15 tourist resorts in three geographic regions of the State of Sao Paulo (Brazil). The study was based on the cases reported to the Epidemic Surveillance Center (CVE) of the Public Health Authority of the State of São Paulo (SES), from 2002 to 2005. The tourist centers were chosen at random in three regions of the state (Capital, Interior and Coast) and offered the following attractions: events, agribusiness, cultural history, shopping, town center, gastronomy, health and leisure, sun and sea. Among the bacteria, the results showed that Salmonella spp. were most frequently associated with outbreaks, followed by Shigella spp., enterotoxigenic Escherichia coli, Staphylococcus aureus, Clostridium perfringens, Bacillus cereus and Campylobacter spp. Viruses (Rotavirus and Hepatitis A) played a part in many of the cases, while the frequency of parasites and worm infestations was low in the foodborne disease outbreaks at these resorts. The mixed foods (rice, beans, liver, potatoes, barbecue, juice), fish and poultry were the three commonest vehicles implicated in the outbreaks.

Fatores de risco para doenças cardiovasculares em idosos com diabetes mellitus tipo 2

The aim of this study was to analyze the risk factors related to the cardiovascular diseases (CVRF) in elderly type 2 diabetics. A cross-sectional observational study was carried out on 100 elderly patients attending the Rehabilitation Center of Araraquara (CRRA), São Paulo State, Brazil, from March to December, 2004. The majority were married, female, white, with a low income and low educational level. Regarding habits and style of life, the subjects had an adequate diet, were sedentary, non-smoking and non-drinking. In the population of 100, 42% were overweight, 42% obese, 71% had above-normal waist measurements and 84% high waist-to-hip ratios. Concerning the CVRF, it was observed that more than half had hypertension, hypercholesterolaemia and hypertriglyceridaemia. 84% had high values of LDL-cholesterol and 59% HDL-cholesterol levels below the reference values, 78% high levels of fasting glycemia, 76% glycohemoglobin and 57% fibrinogen and thus subject to cardiovascular risk. The results showed a high frequency of cardiovascular risk factors, differing according to sex and the age.

Susceptibilidade in vitro a antimicrobianos da Mannheimia haemolytica e da Pasteurella multocida isoladas de ovinos sadios e com doenças respiratórias

Pasteurella multocida and Mannheimia haemolytica (P. haemolytica) are associated with ovine respiratory diseases. With the purpose of observe the susceptibility in vitro of these organisms against antimicrobials, were collected samples of nasopharingeal (n=180) and oropharingeal (n=82) from ovines healthy and with respiratory disease. Among the antimicrobials tested, the sensibility was greater for enrofloxacin (100%) and florfenicol (100%), for both bacteria. The greater resistance indices for M. haemolytica and P. multocida were observed with tetracyclin (15.64% and 17.65% respectively) and penicillin (1.82% and 4.2%).

Efeitos terapêuticos da suplementação de L-arginina nas doenças cardiovasculares e endócrino-metabólicas

Nitric oxide is synthesized from L-arginine and plays an important role in blood pressure regulation, platelets aggregation and atherosclerosis development. Most of the studies have shown that the beneficial effects of the L-arginine supplementation are related to an increasing of nitric oxide bioavailability to the cells, improving the endothelial dysfunction, decreasing oxidative stress, ameliorating lipid profile and insulin resistance. However some studies show conflicting results. Considering the role of the endothelium on the pathogenesis of the cardiovascular diseases as well as on the endocrine-metabolic diseases, this review will update studies involving the role of nitric oxide and its signaling pathways in the regulation of vascular function. Furthermore, this review will focus on the main results of the clinical trials using oral L-arginine supplementation, with or without physical exercise, in an attempt to obtain beneficial effects on the cardiovascular and endocrine-metabolic systems in patients and healthy subjects.

Análise das prevalências de doenças detectadas pelo programa nacional de triagem neonatal no município de Araraquara no ano de 2009

The National Neonatal Screening Program (NNSP) set up in all Brazil, aims, through planned phases of local implementation, to detect diseases such as phenylketonuria, congenital hypothyroidism, hemoglobinopathies and cystic fibrosis. The aim of this study was to assess, through a cross-sectional observational study, the prevalence of the diseases detected by the NNSP in the city of Araraquara, in records issued by the São Paulo APAE laboratory in the period between April and December 2009.The results show that Araraquara had a prevalence of phenylketonuria and congenital hypothyroidism 0.06% above the national averages of 0.01% and 0.03% respectively. With respect to hemoglobinopathies, the prevalence of sickle cell trait was 2.15% below the national average of 2.6%. The prevalence of Hb C in the city was 0.57%, similar to national values reported in the literature. Confirmed Hb Bart's had a prevalence of 0.13% in Araraquara, below the average of 0.38% for the surrounding region. The neonatal screening by heel-prick test and counseling for caregivers are important factors in reducing morbidity related to the evolution of these diseases.
