Semiologia neurológica numa população de escolares da primeira série do ensino fundamental

We evaluated children in the first grade of a elementary school using neurological examination. With no previous knowledgement of their educational performance, were invited all children attending five classes of the first grade of an elementary public school chosen randomly, in Itatiba / Sao Paulo / Brazil, whose parents assigned a Commitment Term for participation in this research. Children who missed three evaluations in different days or whose parents did not assigned the Commitment Term were excluded. The Traditional Neurological Examination (ENT) (Lefevre, 1972) was applied. It was considered for normal the measurement of the skull circumference, proposed by Diament & Rodrigues (1976), and the application of all ENT items. The data were stored in a database of the Epi6 Program (Epidemiologic Information), and analyzed by percentage calculation and by the c2 test. The significance level was 0.05. Children evaluated were 124. The ENT results were normal in 87 (70.16%) and altered in 37 (29.83%). Among the alterations, there were observed: light tremor, light muscular hypotonia, speech acquisition delay, macrocephaly, microcephaly, hyperactivity, cranial nerve syndrome, central facial paralysis. One child presented corticospinal tract impairment syndrome of the distal lower extremities.

CROMATOGRAFIA DE AFINIDADE COM CORANTE RED A versus TROCA IÔNICA-PERMEABILIDADE EM GEL: COMPARAÇÃO DA PRATICIDADE NA PURIFICAÇÃO DE ENTEROTOXINA ESTAFILOCÓCICA A

Culture supernatant of Staphylococcus aureus 722 in 3% triptone plus 1% yeast extract was used for EEA purification, proceeding comparison between dye ligand Red A affinity chromatography and classic chromatography. The capture of SEA with Amberlite CG-50 allowed rapid enterotoxin concentration from the culture supernatant. However, the ratio of 15 mg of the resin to a total of 150 mg of the toxin satured the resin, giving only 10 to 30% of SEA recuperation from the supernatant. The elution of concentrated material throught the Red A column resulted in a recovery of 60,87% of the toxin, and required 76 hours, indicating advantage on classic chromatography. Ion exchange column plus gel filtration recovered only 6,5 % of the SEA, and required 114 hours to conclude the procedure. The eletrophoresis of purified SEA indicated high grade of toxin obtained from Red A column, with 90 % of purity, compared to 60 % of classic column.

Análise de atitudes de professoras do ensino fundamental no que se refere à educação inclusiva

Este artigo, que tem como referência a teoria crítica, relata o resultado de uma pesquisa sobre atitudes em relação à educação inclusiva, realizada com doze professoras do 5º ano do ensino fundamental; dentre elas, seis tinham experiência de ter em sala de aula alunos com deficiência, e seis não tinham. A análise qualitativa dos dados decorrentes do levantamento realizado em seis escolas da rede municipal de Campo Grande (MS) demonstrou que, de modo geral, as professoras foram favoráveis à educação inclusiva. Contudo, ficou evidente a expressão de atitudes preconceituosas veladas ou explícitas no âmbito escolar. A formação para experiência com quem é "diferente" ainda encontra barreiras por conta do preconceito e da discriminação presentes nesta sociedade que tem como lógica uma "inclusão marginal". Em suas manifestações, apontaram dificuldades de trabalhar com alunos com deficiência intelectual severa; assinalaram que a responsabilidade de trabalhar sob a predominância da educação centrada no desempenho, com foco na inserção das pessoas no mercado de trabalho, gerava um "sentimento de impotência". Diante das contradições existentes, a educação inclusiva não deixa de evidenciar a presença das injustiças que ainda se apresentam no processo educativo. Apesar disso, foram indicados vários elementos favoráveis a essa forma de educação, que não é dissociada de movimentos sociais mais amplos.

Consumo e comportamento alimentar entre adolescentes brasileiros: Pesquisa Nacional de Saúde do Escolar (PeNSE), 2009

O objetivo deste artigo é descrever características de consumo e comportamento alimentar de adolescentes brasileiros e sua associação com fatores sociodemográficos. Estudou-se, em 2009, amostra representativa de alunos do 9º ano do ensino fundamental de escolas públicas e privadas das 26 capitais brasileiras e do Distrito Federal. Utilizou-se questionário autoaplicável sobre atributos sociodemográficos, consumo e comportamento alimentar, entre outros. Estimativas dos indicadores construídos foram apresentadas para o total da população e por sexo. A associação de cada um dos indicadores com variáveis sociodemográficas foi examinada por meio de regressão logística. A maioria dos adolescentes consumia regularmente feijão (62,6%), leite (53,6%) e guloseimas (50,9%), realizava pelo menos o almoço ou o jantar com a mãe ou responsável (62,6%) e comia assistindo televisão ou estudando (50,9%). Em geral, as meninas estavam mais expostas a práticas alimentares não desejáveis, e o melhor nível socioeconômico associou-se a maiores prevalências dos indicadores estudados. Os resultados revelaram consumo regular dos marcadores de alimentação não saudável e consumo inferior ao recomendado dos de alimentação saudável, apontando a necessidade de ações de promoção de saúde dirigidas a jovens.

Prevalência e fatores associados ao tabagismo em escolares da Região Sul do Brasil

OBJETIVO: Estimar a prevalência do tabagismo em estudantes e os fatores associados.MÉTODOS: Foram utilizados dados secundários, provenientes do inquérito Vigescola realizado em Curitiba (PR), Florianópolis (SC) e Porto Alegre (RS) em 2002 e 2004. A amostra compreendeu 3.690 escolares de 13 a 15 anos, cursando as sétima e oitava séries do ensino fundamental e primeira do ensino médio, em escolas públicas e privadas. Para a análise dos resultados foram estimadas proporções ponderadas, odds ratio (OR), e utilizada a técnica de regressão logística múltipla.RESULTADOS: As taxas de prevalência de tabagismo corresponderam a 10,7 por cento (IC 95 por cento: 10,2;11,3) em Florianópolis, 12,6 por cento (IC 95 por cento: 12,4;12,9) em Curitiba e 17,7 por cento (IC 95 por cento: 17,4;18,0) em Porto Alegre. Os fatores associados ao tabagismo em escolares em Curitiba foram: sexo feminino (OR=1,49), pai fumante (OR=1,59), amigos fumantes (OR=3,46), exposição à fumaça do tabaco fora de casa (OR=3,26) e possuir algum objeto com logotipo de marca de cigarro (OR=3,29). Em Florianópolis, as variáveis associadas ao tabagismo foram escolares do sexo feminino (OR=1,26), ter amigos fumantes (OR=9,31), exposição à fumaça do tabaco em casa (OR=2,03) e fora de casa (OR=1,45) e ter visto propaganda em cartazes (OR=1,82). Em Porto Alegre, as variáveis que estiveram associadas com o uso de tabaco pelos escolares foram sexo feminino (OR=1,57), idade entre 14 anos (OR=1,77) e 15 anos (OR=2,89), amigos fumantes (OR=9,12), exposição à fumaça do tabaco em casa (OR=1,87) e fora de casa (OR=1,77) e possuir algo com logotipo de marca de cigarro (OR=2,83).CONCLUSÕES: Há elevada prevalência de tabagismo entre escolares de 13 a 15 anos, cujos fatores significativamente associados comuns às três capitais são: ter amigos fumantes e estar exposto à fumaça ambiental fora de casa

Increased hepatic iron concentration in nonalcoholic steatohepatitis is associated with increased fibrosis

Background & Aims: Nonalcoholic steatohepatitis (NASH) is a chronic liver disease that occasionally progresses to cirrhosis but usually has a benign course. The aim of this study was to investigate the role of the hemochromatosis mutation Cys282Tyr in development of the mild hepatic iron overload found in some patients with NASH and its association with hepatic damage in these patients. Methods: Fifty-one patients with NASH were studied. The presence of the Cys282Tyr mutation was tested in all patients, and the data were analyzed with respect to the histological grade of steatosis, inflammation, Perls' staining, hepatic iron concentration (HIC), and serum iron indices. Results: Thirty-one percent of patients with NASH were either homozygous or heterozygous for the Cys282Tyr mutation. This mutation was significantly associated with Perls' stain grade (P < 0.005), HIC (P < 0.005), and transferrin saturation percentage (P < 0.005) but not with serum ferritin levels. Linear regression analysis showed that increased hepatic iron (Perls' stain or HIC) had the greatest association with the severity of fibrosis (P < 0.0001). Conclusions: The Cys282Tyr mutation is responsible for most of the mild iron overload found in NASH and thus has a significant association with hepatic damage in these patients. Heterozygosity for the hemochromatosis gene mutation therefore cannot always be considered benign.

Is the ultrasound-estimated bladder weight a reliable method for evaluating bladder outlet obstruction?

OBJECTIVE To evaluate the correlation between ultrasound-estimated bladder weight (UEBW) in patients with different degrees of bladder outlet obstruction (BOO). METHODS We evaluated 50 consecutive non-neurogenic male patients with lower urinary tract symptoms (LUTS) referred to urodynamic study (UDS). All patients self-answered the International Prostate Score Symptoms (IPSS) questionnaire. After the UDS, the bladder was filled with 150 mL to determine UEBW. Patients with a bladder capacity under 150 mL, a previous history of prostate surgery or pelvic irradiation, an IPSS score <8, a bladder stone or urinary tract infection were excluded. After a pressure-flow study, the Schafer linear passive urethral resistance relation nomogram was plotted to determine the grade of obstruction: Grades I-II/VI were defined as mild obstruction, Grades III-IV/VI as moderate obstruction, and Grades V-VI/VI as severe obstruction. RESULTS The UEBW was 51.7 +/- 26.9, 54.1 +/- 30.0 and 54.8 +/- 28.2 in patients with mild, moderate and severe BOO, respectively (P = 0.130). The UEBW allowed us to define four groups: (i) UEBW < 35 g; (ii) 35 g <= UEBW < 50 g; (iii) 50 g <= UEBW < 70 g; and (4) UEBW >= 70 g. We did not find any differences in age, prostate weight, IPSS, PVR, cystometric bladder capacity, presence of detrusor overactive and degree of obstruction in the aforementioned groups. CONCLUSION Despite the fact that some studies have emphasized the value of UEBW as an efficient non-invasive method for evaluating lower urinary tract obstruction, our study suggests that UEBW does not present any individual correlation with LUTS or objective measurements of BOO.

Chronic hepatitis C: Hepatic fibrosis evolution after ineffective specific treatment

Background/Aims: Specific treatment of chronic hepatitis C is effective in 50% of patients, improving the]liver`s fibrosis, necroinflammatory changes and steatosis. However, in patients still viremic after treatment the extension of these benefits remains doubtful. The evolution of the disease in this group and its relationship to demographic data, biometric indices and time lapse between biopsies was evaluated. Methodology: In 141 patients, paired biopsies were classified and compared according to fibrosis grading. Necroinflammation, steatosis, demographic data (age and gender), body mass index (BMI) and time lapse between biopsies were compared with fibrosis grading. Results: The grade of fibrosis of the patients, after approximately 3.5 years time lapse between biopsies, could be classified into 4 groups; Improved: 29(20.0%), Unaltered: 64(45.0%), Worsened: 48(34%) and Cirrhotic: 14(9.93%). For necroinflammation, the Improved/Unaltered groups were statistically similar but different from the Worsened and Cirrhotic. The mean age, BMI and time lapse between biopsies were statistically similar in all groups. Steatosis occurred in 35 (24.82%) between biopsies and its incidence was reduced in the Worsened and Cirrhotic groups. Conclusions: Fibrosis turned into cirrhosis in a significant number of patients, after a short time lapse. The reverse correlation of steatosis to fibrosis and its occurrence during the time lapse between biopsies suggests it might induce hepatic necrosis and contribute to fibrogenesis.

Classical and non-classical HLA molecules and p16(INK4a) expression in precursors lesions and invasive cervical cancer

Objectives: Viruses and turnout cells may regulate the expression of HLA molecules on the cell surface to escape immune system surveillance. Absence of classical HLA class I molecules may impair the action of specific cytotoxic cells, whereas non-classical HLA class I molecules may regulate innate and adaptive immune cells. We assess here the possible associations between classical/non-classical class I HLA and p16(INK4a) molecule expression in cervical biopsies of women infected with HPV, stratified according to grade of the lesion and HPV type. Study design: Cervical biopsies (N = 74) presenting cervical intraepithelial neoplasia grade 1 (CIN1) (n = 31), CIN2-3 (n = 19), and invasive cancer (n = 14) were evaluated alongside 10 normal cervical specimens. Results: HLA-A/B/C/G staining was observed in the early stages of HPV infection. A significant association was detected between HLA-A/B/C staining and HPV16/18 infection (OR = 0.12, 95%CI: 0.0163-0.7899; p = 0.04). HLA-E expression increased with the progression of the lesion (chi(2)-test for trend = 4.01; p = 0.05), and a significant association was found between HLA-E staining and HPV16/18 infection (OR = 11.25, 95%CI: 2.324-54.465; p = 0.003). Irrespective of the grade of the lesion, HLA-A/B/C staining and p16(INK4a) presented a good concordance (Kappa: 0.67). Conclusions: HLA-E overexpression seemed to be associated with invasive cancer and HPV16/18 infection. (C) 2008 Elsevier Ireland Ltd. All rights reserved.
