Densidad mineral ósea en escolares nacidos prematuros Bone mineral density in school age infants born preterm
Aída Milinarsky T,Sylvia Fischer G,Vinka Giadrosich R,María Isabel Hernández C
Revista médica de Chile , 2003,
Abstract: The age at which children born preterm normalize their bone mineral density, is not well known. Aim: To study if children born preterm have normalized their bone mineral density at age 5 to 7 years. Patients and methods: Twenty six infants born preterm (14 male), were studied at age 5 to 7 years. Birth weight, present weight and height, bone age, calcium and phosphate intake at the first year of life and at the current age were assessed. Bone mineral density was measured by single photon X ray absorptiometry in the dominant forearm. A blood sample was obtained to measure insulin growth factor 1 (IGF-1). As a control group, 105 healthy age-paired infants born at term, were studied. Results: Bone mineral density was significantly lower in infants born preterm than in their term counterparts (0.273±0.01 g/cm2 and 0.302±0.01 g/cm2 respectively, p <0.001). There was a positive correlation between bone mineral density and IGF-1 (r=0.49, p=0.01). No correlation with the other measured parameters was observed. Conclusions: Infants that were born preterm have a lower bone mineral density at 5 to 7 years of age than their term controls. Bone mineral density correlates with IGF-1 (Rev Méd Chile 2003; 131: 1289-94).
Efecto de dosis altas de budesonida y función suprarrenal de ni os asmáticos severos High doses of inhaled budesonide and adrenal function in children with severe asthma
Aída Milinarsky T,Sylvia Fischer G,Vinka Giadrosich R,Viviana Lezana S
Revista médica de Chile , 2006,
Abstract: Background: The use of inhaled steroids is common in the treatment of bronchial asthma in children. Aim: To assess adrenocortical function in children with severe asthma receiving inhaled budesonide for six or more months. Material and methods: Children with severe asthma that required 800 μg/day or more of inhaled budesonide and that did not required systemic steroids for more than six days in the last four months to control their disease, were studied. Serum cortisol was measured one hour after administration of 0.25 mg of ACTH (Cosyntropin ) intravenously. The test was considered normal if post stimulation serum cortisol was over 18 μg/ml. Results: Twenty children (aged 5 to 14 years, 15 males), were studied. The stimulation test was normal in 17 children. Conclusions: Alterations in adrenal function are present in a small proportion of asthmatic children who require 800 μg/day of inhaled budesonide

Práticas disciplinares inauguradas com a República no ensino secundário paranaense
Ranzi, Serlei Maria Fischer;Silva, Maclovia Corrêa da;
Pro-Posi??es , 2009, DOI: 10.1590/S0103-73072009000100009
Abstract: this paper brings an analysis of the creation and application of disciplinary practices at an institution called ginásio paranaense from 1896 to 1930. the discussion has its bases on the disciplinary power interposed between the kinds of subjects involved, both in the classroom environment and and in the institution responsible for high school organization in paraná. the members of the congregation and the principal were the people responsible for interpreting and accomplishing the school regiment in such a way that flaws would correspond to penalties, so that they would be able to "tame" the "delinquents". the disciplinary practices inaugurated with the republican government depended on the constant regulation of penalties and competences. this analysis was useful in adding tools to the present discussion by explaining the mobilization of power relations which, along time, were disciplinary and characterized schools as stages for daily life experiences.
Electrolytic Balance in Broiler Chicks During the First Week of Age
Borges SA,Maiorka A,Laurentiz AC,Fischer da Silva AV
Revista Brasileira de Ciência Avícola , 2002,
Abstract: Two experiments were carried out using 712 day-old chicks to evaluate the electrolytic balance (Na+K-Cl) in pre-starter (1-7 days) broiler diets. The feed, based on corn and soybean meal with 21.5 % protein and 2,900 kcal ME/kg, was offered ad libitum. In experiment I, K level was fixed, and Na and Cl levels were changed, using four 4 treatments and eight replicates of 16 birds. In experiment II, increasing levels of Na and K were used, with a total of four treatments and five repetitions of 10 birds. In both experiments, the dietary electrolytic balance was 40; 140; 240 and 340 mEq/kg. Electrolytic balance caused a quadratic effect on weight gain and feed:gain ratio, and a linear increase in feed intake when the electrolytic balance was increased by the single supplementation of Na, indicating that this ion stimulates feed intake of birds at this stage. However, feed intake was maximum for 202 mEq/kg, when K and Na levels were concurrently increased in the diet, indicating that there is a limit over which feed intake is depressed as a function of excessive K. The ideal electrolytic dietary balance was between 246 and 277 mEq/kg, obtained by the manipulation of Na and Cl levels.
Desenvolvimento do Trato Gastrointestinal de Embri es Oriundos de Matrizes Pesadas de 30 e 60 Semanas de Idade
Maiorka A,Santin E,Fischer da Silva AV,Bruno LDG
Revista Brasileira de Ciência Avícola , 2000,
Abstract: O objetivo deste trabalho foi investigar o efeito da idade das matrizes pesadas sobre o desenvolvimento do trato gastrointestinal (TGI) dos embri es no ter o final do período de incuba o, bem como a utiliza o das reservas do saco vitelino nas 24 h pós-eclos o, em pintos alimentados ou em jejum. Foram utilizados ovos férteis da linhagem Cobb 500, oriundos de matrizes pesadas com 30 e 60 semanas de idade. O desenvolvimento do TGI (proventrículo+moela, segmentos do intestino delgado e saco vitelino) foi estudado entre o 17o e 21o dias de incuba o (Experimento 1). Nas 24 h pós-eclos o foi pesquisado o efeito da presen a ou n o de alimento no lúmen intestinal sobre a utiliza o das reservas do saco vitelino (Experimento 2). Os achados deste trabalho mostraram que, ao contrário do embri o, o desenvolvimento do intestino delgado e o peso do saco vitelino n o sofreram influência da idade das matrizes. Na fase pós-eclos o, na ausência de alimento, o desenvolvimento do intestino delgado foi maior nas matrizes com 60 semanas, sendo dependente do crescimento do jejuno. A presen a do alimento no lúmen teve influência na utiliza o das reservas do saco vitelino apenas nas matrizes com 30 semanas de idade. Os resultados deste experimento mostraram que a idade da matriz é importante fator no desenvolvimento do trato gastrointestinal do embri o, sendo fator relevante no crescimento pós-eclo o dos pintos.
Quest es de legitimidade na primeira República: o ensino secundário regular a equipara o do Ginásio Paranaense ao congênere federal
Serlei Maria Fischer Ranzi,Maclovia Corrêa da Silva
Educa??o : Revista do Centro de Educa??o UFSM , 2006,
Abstract: Este texto trata do Ginásio Paranaense e dos esfor os de dirigentes locais para obter a equipara o ao Ginásio Nacional. O período de 1889 a 1930, recorte estabelecido para o estudo, reflete um momento de intenso debate sobre esta quest o delineada nos ideais republicanos e presentes também nas idéias de legitima o e hierarquiza o do ensino secundário. Ao estudarmos as tens es que permearam o processo de equipara o, manifestadas no universo das práticas em disputa, verificamos que qualquer postura contestada se insinuava como amea adora no interior do movimento rumo ao novo. Foi possível observar, a partir de uma análise local, como os governantes republicanos construíram uma hierarquia das legitimidades e de prestígio de um curso de humanidades, com pretens o à consagra o daquilo que era considerado vanguarda nas escolas secundárias espalhadas pela Europa e pelos Estados Unidos. Palavras-chave: Ensino Secundário. Processo de Equipara o e Legitima o. Práticas em Disputa.
