This current work s contains issues about the educative dimension of work and its organization s process and managing for it own professionals. It aims to understand how the skills and pedagogic process, in a educative praxis perspective. Are based in a new culture of work of education process an work managing by workers in Handcraft Association of Serido/ Caicó/ RN. It uses as a methodologic-theoric reference cases s study approach, selecting the procedures of part extructure interview. It was done with six embroidereses from the Handcraft Association. The research shows that the educative process of learning and knowledges construction, in the work and by the work. Those processes develop in exchange experiences net in a friendly economic environment and raise elements of a work culture personal that work there. The embroidereses learn how to embroid doing the job and this learning, a lot of times, is influenced by the life conditions, residence local and infantile work in the country area and the living to the urban area, particularly to Caicó. The knowledge relation between them is the matter fact in the embroider learning process that means a social relation based on the knowledge differences between their position in its structure involving the work division, that each handcraft maker knows every part of the embroider, type of work or machine type, step by step until the work is done. It involves decision, execution and machine movements repetition, the focus are the categories that fit in current flexible financial issue. They schedule the work at home so they have time to do other stuff. Most part of the production currently is done to obey de a certain request that aims as production target, being a homework. Another important issue is the embroider work time: time and experience that is within in the professional life and its knowledge representation of job/profession. This time is got as a acquisition process of certain a work dominion and self knowing; time added to changes that were being there practicing from the new characteristics in the furniture, clothes and towels that are in the introduction communicative and its effect. In this way this work include articulations process among skills, educative process and handcraft work organization that allowed the interpretation and finish, that are related to the case study and its developments: handcraft embroidered considered as a profession, money source not conventional where is not work available and a temporary activity while studyng, homework and flexible work

Infantile botulism was recognized in 1976 as a paralyzing disease caused by the ingestion of viable spores that would germinate and colonize the intestinal tract of infants, with local production and absorption of Clostridium botulinum toxin. The possible origins of botulinic spores are dust and honey, which has been identified as a dietary risk factor for infantile botulism. The objectives of the present study were to investigate 100 honey samples obtained in the state of São Paulo (Brazil) in terms of incidence of botulinic spores and of microbiologic quality, in agreement with Decree 367/9. All 100 samples analysed were negative for the presence of Salmonella, Shigella, total coliforms. C botulinum spores were present in 3 samples (3%) and molds and yeasts, in 64 samples (64%), but only 25 (25%) exceeded established criteria, with counts ranging from zero to 1.5 x 10(5) CFU/g. The presence of small sporogenic Gram-positive rods was observed in 42 (42%) of the 100 samples tested but these bacteria were not identified. (C) 2003 Elsevier Ltd. All rights reserved.

A violência contra crianças é apontada como uma das principais causas de morbi-mortalidade na infância e deve ser identificada por todos os profissionais que lidam com esse público, inclusive os professores. Objetivou-se avaliar o preparo dos professores de educação infantil, no que se refere à percepção e notificação dos casos de violência contra criança. Foram visitadas todas as instituições de ensino infantil de Araçatuba-SP, e os profissionais que consentiram (n=236), os quais responderam a um questionário sobre o tema. Os dados foram analisados quanti-qualitativamente. 91,1% se consideram responsáveis pela notificação e 86,9% se dizem capazes de identificar agressões. 80,9% declararam ter recebido informações a respeito da violência contra criança, entretanto, 67,7% sentem-se inseguros quanto à identificação dos casos. Conclui-se que, mesmo possuindo formação para proceder ante a violência, a maioria dos pesquisados ainda não se sente preparada, o que pode gerar negligência.

Os nódulos vocais são causas freqüentes de disfonias infantis, porém, através das vídeoendoscopias, outras lesões têm sido diagnosticadas na laringe infantil, como os cistos, sulcos, pontes e micromembranas, denominadas de lesões estruturais mínimas. OBJETIVO: Avaliar, em 71 crianças com disfonia agendadas nos ambulatórios de Foniatria da Faculdade de Medicina de Botucatu (Unesp) nos últimos cinco anos: sexo, idade, diagnósticos, tratamentos e evolução clínica. FORMA DE ESTUDO: Clínico retrospectivo. CASUÍSTICA E MÉTODO: Realizou-se estudo retrospectivo das avaliações otorrinolaringológicas e endoscópicas de 71 crianças com queixas de disfonia e idade entre 3 a 13 anos (45 meninos e 26 meninas). As crianças haviam sido submetidas a exame endoscópico com telescópio rígido ou nasofibroscópio flexível. Foram excluídas as crianças com disfonias funcionais ou com queixas de obstrução respiratória. RESULTADOS: Os principais diagnósticos foram: nódulo vocal (47 casos; 66,2%), cisto epidérmico (7 casos; 9,9%), cisto aberto fistulizado (6 casos; 8,4%), sulco vocal (5 casos; 7,1%), ponte + cisto (2 casos; 2,8%), micromembrana anterior (2 casos; 2,8%) e pólipo vocal (2 casos; 2,8%). As disfonias foram mais freqüentes entre os meninos (63,3%). A fonoterapia isolada foi o tratamento de escolha nos casos de nódulo vocal (evolução favorável), sulco vocal (evolução desfavorável) e micro-membrana (evolução desfavorável). Nas demais lesões (cistos, pontes e pólipos) o tratamento de escolha foi a cirurgia associada à fonoterapia, com resultados satisfatórios, exceto nos casos que recusaram a cirurgia. CONCLUSÃO: Os nódulos vocais são as principais causas de disfonias em crianças, porém as lesões estruturais mínimas mostraram-se também freqüentes, exigindo exame minucioso para o diagnóstico.

Este estudo objetivou verificar a compreensão das experiências dos familiares em relação ao cuidado com a saúde bucal das crianças. É estudo qualitativo, realizado em 2007, em distrito de saúde do município de Ribeirão Preto, SP, com 12 cuidadores. Utilizou-se referencial teórico da vulnerabilidade e a perspectiva hermenêutica. Três categorias empíricas foram elaboradas: os significados do cuidado com a saúde bucal, em busca das causas e da prevenção de agravos bucais e a realidade dos serviços de saúde bucal. Entre outros elementos potencializadores da vulnerabilidade infantil aos agravos bucais, emergiu a supervalorização da causalidade biológica, do atendimento de alta complexidade e da odontologia estética e, entre os protetores, a valorização do saber popular e a integração de ações e conhecimentos profissionais. Aponta-se para a revisão das estratégias de prevenção e promoção de saúde bucal, fornecendo elementos para auxiliar os serviços de saúde a reorganizarem o cuidado com a saúde bucal de crianças.

We have analyzed 16 missense mutations of the tissue-nonspecific AP (TNAP) gene found in patients with hypophosphatasia. These mutations span the phenotypic spectrum of the disease, from the lethal perinatal/infantile forms to the less severe adult and odontohypophosphatasia. Site-directed mutagenesis was used to introduce a sequence tag into the TNAP cDNA and eliminate the glycosylphosphatidylinositol (GPI)-anchor recognition sequence to produce a secreted epitope-tagged TNAP (setTNAP). The properties of GPI-anchored TNAP (gpiTNAP) and setTNAP were found comparable. After introducing each single hypophosphatasia mutation, the setTNAP and mutant TNAP cDNAs were expressed in COS-1 cells and the recombinant flagged enzymes were affinity purified. We characterized the kinetic behavior, inhibition, and heat stability properties of each mutant using the artificial substrate p-nitrophenylphosphate (pNPP) at pH 9.8. We also determined the ability of the mutants to metabolize two natural substrates of TNAP, that is, pyridoxal-5'-phosphate (PLP) and inorganic pyrophosphate (PPi), at physiological pH. Six of the mutant enzymes were completely devoid of catalytic activity (R54C, R54P, A94T, R206W, G317D, and V365I), and 10 others (A16V, A115V, A160T, A162T, E174K, E174G, D277A, E281K, D361V, and G439R) showed various levels of residual activity. The A160T substitution was found to decrease the catalytic efficiency of the mutant enzyme toward pNPP to retain normal activity toward PPi and to display increased activity toward PLP. The A162T substitution caused a considerable reduction in the pNPPase, PPiase, and PLPase activities of the mutant enzyme. The D277A mutant was found to maintain high catalytic efficiency toward pNPP as substrate but not against PLP or PPi. Three mutations ( E174G, E174K, and E281K) were found to retain normal or slightly subnormal catalytic efficiency toward pNPP and PPi but not against PLP. Because abnormalities in PLP metabolism have been shown to cause epileptic seizures in mice null for the TNAP gene, these kinetic data help explain the variable expressivity of epileptic seizures in hypophosphatasia patients.

Enteropathogenic Escherichia coli ( EPEC) strains are important agents of infantile diarrhea all over the world, gaining even greater importance in developing countries. EPEC have also been isolated from various animal species, but most isolates belong to serotypes that differ from those recovered from humans. However, it has been demonstrated that several isolates from non- human primates belong to the serogroups and/ or serotypes related to those implicated in human disease. The objective of this study was to evaluate the genetic differences between thirteen strains isolated from non- human primates and the same number of strains isolated from human infections. Human isolates belonged to the same serogroup/ serotype as the monkey strains and the evaluation was done by analysis of random amplified polymorphic DNA. Dendrogram analysis showed that there was no clustering between human and monkey strains. Human and non- human isolates of the EPEC serotypes O127:H40 and O128:H2 shared 90 and 87% of their bands, respectively, indicating strong genomic similarity between the strains, leading to the speculation that they may have arisen from the same pathogenic clone. To our knowledge, this study is the first one comparing genomic similarity between human and non- human primate strains and the results provide further evidence that monkey EPEC strains correlate with human EPEC, as suggested in a previous investigation.

The immunological status of five children with West syndrome consequent to previous cerebral lesions was investigated. Three children had West syndrome and two were in transition from West to Lennox-Gastaut syndrome. All of them showed cellular immunological deficiencies in the following tests: sensitization to DNCB, intracutaneous reaction to PHA, inhibition of leukocyte migration, blastic transformation of lymphocytes, T and B lymphocytes in peripheral blood and levels of serum immunoglobulins. These immunological deficiencies, of different degrees of severity, were associated with frequent infections in these children. A possible association between the immunological deficiencies and autoimmunity is discussed.

The nutritional management of infants admitted with diarrhoea to the University Hospital of Botucatu includes a change from bolus feeding of a modulated minced-chicken formula to a continuous nasogastric drip (NGD) feeding, whenever the required calorie intake is not achieved or the diarrhoea does not subside. To evaluate this approach, the clinical course and weight changes of 63 children, aged 1-20 months, were reviewed; most (81 per cent) were below the third percentile for weight at admission and 76 per cent had a total duration of diarrhoea ≥10 days. Associated infections, mainly systemic, were present at or after admission in 70 per cent of them. Twenty-five survivors needed nutritional support (NS), predominantly NGD, for a median duration of 30 per cent of their admission time, and were compared to 31 survivors managed without NS. Those who necessitated NS lost weight for a significantly longer median time (12x4 days, p<0.005), but their total weight loss was similar (5x4 per cent) as well as diarrhoea's duration (8x7 days). There was a tendency for a longer hospitalization (21x16 days 0.05

The clinical, radiological, pathological and laboratory findings of two brothers with autosomal recessive malignant osteopetrosis are presented. Our findings are similar to characteristics previously reported in the literature about patients with osteopetrosis. The 6-year-old male patient was pale and had petechiae on his arms and legs. He also had macrocephalia, splenomegaly, severe pancytopenia, genu valgus, hypocalcemia, amaurosis, cessation of physical development, generalized bone sclerosis and recurrent infections with a history of multiple incidences of acute otitis media. Generalized bone sclerosis and irregular sclerosis of the maxilla and mandible were seen on radiographs. The oral mucosa was apparently normal but permanent tooth eruption was delayed although there was early loss of deciduous teeth. The recommended treatment was blood transfusion and therapy with antibiotics when necessary; a bone marrow transplant was not possible due to lack of a compatible donor.
