This article is part of a study considering the growing importance of the international transit of people, knowledge, and practices in the schooling and professional education processes of some social segments. Considering the public funds made available by the Coordination for the Improvement of Higher Education Personnel - Capes -, the National Council for Scientific and Technological Development - CNPq - and the State of São Paulo Research Foundation - Fapesp - to support researchers' fellowships abroad, aming to improve research and investments on Science and Technology on the context of international exchanges, we have dedicated this article to the preliminary description and analysis of the database of fellows funded abroad by these research agencies from 1970 to 2000. The movement of flows based on the quantitative methodology of the correlation of variables draws the trends of international academic exchange programs in the three research institutions and in the different areas of knowledge, and we intend to analyse them taking into account the scientific and technological development policies adopted by Brazilian State on the period.

OBJETIVE: Investigate the cardiopulmonary responses of one strength training session in young women. METHOD: Twenty-three women aged between 18 and 29 years participated in this study. All the volunteers were submitted to the following tests: cardiopulmonary and one-repetition maximum (1-RM). The strength training protocol had emphasis on muscular hypertrophy, three sets from eight to twelve repetitions under 70% of 1-RM, with a one minute thirty-second break between sets. During the training session, the cardiopulmonary variables were measured with a metabolic gas analyzer and a telemetry module. RESULTS: The results of the oxygen consumption in the training session were from 8.43 + 1.76 ml/kg/min and of the heart rate of 108.08 + 15.26 bpm. The results of the oxygen consumption and of the heart rate in the training were lower (p < 0.01) than in the ventilatory threshold and of the oxygen consumption and the heart rate reserves. CONCLUSION: The obtained data show that the present protocol of strength training provided low overload to the cardiopulmonary system of young women.

Multiple endocrine neoplasia type 1 (MEN1) is an autosomal dominant hereditary cancer syndrome characterized mostly by parathyroid, enteropancreatic, and anterior pituitary tumors. We present a case of an 8-year-old boy referred because of hypoglycemic attacks. His diagnosis was pancreatic insulinoma. Paternal grandmother died due to repeated gastroduodenal ulcerations and a paternal aunt presented similar manifestations. At a first evaluation, the father presented only gastric ulceration but subsequently developed hyperparathyroidism and lung carcinoid tumor. During almost 15 years of follow-up, three brothers and the index case presented hyperparathyroidism and hyperprolactinemia. Molecular study showed a G to A substitution in intron 4, at nine nucleotides upstream of the splicing acceptor site, causing a splicing mutation. All affected members of the family have the same mutation. Paternal grandmother and aunt were not studied and the mother does not carry any mutation. MEN1 is a rare condition that requires permanent medical assistance. Early clinical and genetic identification of affected individuals is essential for their own surveillance and also for genetic counseling.

The recombinant human growth hormone (rhGH) can improve weight gain, physical growth, clinical and lung in cystic fibrosis (CF). However, the routine use, although promising, is not established in the literature. The objective of this study was to assess the benefits of rhGH in children and adolescents with CF. We conducted a systematic review in the database PubMed, Lilacs, SciELO and Cochrane, in the period 2000-2010, using the keywords: cystic fibrosis, growth hormone, children and adolescents. We found 77 articles and included 11 randomized controlled trials, with 290 children and adolescents with CF. The short-term use (1-24 months) of rhGH improved the height, weight, growth rate, bone mineral content and components of pulmonary function. Adverse effects, like diabetes, were not observed in the studies. The short-term use of rhGH improved growth and body composition in patients with CF.

The authors describe a family with three members affected by glioblastoma. The proband patient, a 7 year-old girl, developed a rare complication, a pulmonary metastasis. Chromosomal analysis of her peripheral blood lymphocytes showed a normal karyotype (46, XX), without structural abnormalities. Cytogenetic study of the tumor cells disclosed several abnormalities: 46, XX, 7q - / 46, XX, -2, 4p-, 7p-, +15/ 46, XX. Some aspects about genetics of glial neoplasms are discussed.

Aproximadamente sete milhões de brasileiros acima de 40 anos são acometidos pela DPOC. Nos últimos anos, importantes avanços foram registrados no campo do tratamento medicamentoso dessa condição. Foi realizada uma revisão sistemática incluindo artigos originais sobre tratamento farmacológico da DPOC publicados entre 2005 e 2009, indexados em bases de dados nacionais e internacionais e escritos em inglês, espanhol ou português. Artigos com tamanho amostral menor de 100 indivíduos foram excluídos. Os desfechos sintomas, função pulmonar, qualidade de vida, exacerbações, mortalidade e efeitos adversos foram pesquisados. Os artigos foram classificados segundo o critério da Global Initiative for Chronic Obstructive Lung Disease para nível de evidência científica (grau de recomendação A, B e C). Dos 84 artigos selecionados, 40 (47,6%), 18 (21,4%) e 26 (31,0%) foram classificados com graus A, B e C, respectivamente. Das 420 análises oriundas desses artigos, 236 referiam-se à comparação de fármacos contra placebo nos diversos desfechos estudados. Dessas 236 análises, os fármacos mais frequentemente estudados foram anticolinérgicos de longa duração, a combinação β2-agonistas de longa duração + corticosteroides inalatórios e corticosteroides inalatórios isolados em 66, 48 e 42 análises, respectivamente. Nas mesmas análises, os desfechos função pulmonar, efeitos adversos e sintomas geraram 58, 54 e 35 análises, respectivamente. A maioria dos estudos mostrou que os medicamentos aliviaram os sintomas, melhoraram a qualidade de vida, a função pulmonar e preveniram as exacerbações. Poucos estudos contemplaram o desfecho mortalidade, e o papel do tratamento medicamentoso nesse desfecho ainda não está completamente definido. Os fármacos estudados são seguros no manejo da DPOC, com poucos efeitos adversos.
