Um novo escore para opacifica??o tomográfica dos seios paranasais em crian?as
Araújo Neto, Severino Aires de;Baracat, Emílio Carlos Elias;Felipe, Leonardo Franco;
Brazilian Journal of Otorhinolaryngology , 2010, DOI: 10.1590/S1808-86942010000400014
Abstract: many score methods have been created to measure paranasal sinus abnormalities seen under ct scan. currently, the lund-mackay staging system is widely accepted. however, its results may be affected by the development in children. aim: to assess the precision and accuracy of a new tomography score, called "opacification-development ratio". it translates the percentage of sinus area that is opaque. materials and methods: a cross-sectional study was prospectively conducted in patients ranging from 0-18 years of age who underwent ct scan assessment of rhinosinusitis. two independent radiologists examined each scan twice, using both the lund system and the ratio herein proposed. results: the opacification-development ratio reached substantial intra and inter-examiner agreement, similar to the lund system (kappa > 0.60). considering the lund system as the gold standard, the most accurate cut-off point was approximately 15 (sensitivity and specificity approach 90%). there was a strong linear correlation between the two methods (r > 90). conclusions: opacification-development ratio is precise and correlates with the lund system. a cut-off point set at 15 could be used to call a test positive.
Concomitant Use of Glycoprotein IIb/IIIa Inhibitor and Streptokinase after Unsuccessful Rescue Angioplasty

Arquivos Brasileiros de Cardiologia , 2002,
Abstract: A 38-year-old man with acute myocardial infarction in the lower wall affecting the right ventricle underwent thrombolytic treatment with streptokinase. Approximately 2 hours after the thrombolytic treatment started, he presented with signs of coronary reocclusion. He underwent emergency cineangiocoronariography that revealed that his right coronary artery was completely occluded by a clot. He unsuccessfully underwent angioplasty and stent implantation. After the concomitant use of glycoprotein IIb/IIIa inhibitor, coronary TIMI III flow was achieved without additional dilations, and he was discharged from the hospital 5 days later with no further complications.
Group Dynamics in On-Line and Face-to-Face Interactions: An Experimental Study on Learning Methods  [PDF]
Sergio Severino, Roberta Messina
Sociology Mind (SM) , 2011, DOI: 10.4236/sm.2011.12008
Abstract: Organizing in groups does not represent an objective definition, but rather a way to better understand the mean-ing of plurality. At the same time modern technologies modify perceptive and cognitive transformation. This re-search shows that on-line groups develop objective dynamics in face-to-face groups; it evaluates the quality of the University student services and studies the dynamics of the creation of face-to-face and on-line groups. Stu-dents were divided into experimental on-line (forum, chat, newsgroup) and face-to-face encounters (seminars, laboratories). The two level analyses show the defence mechanisms, the lack of socialization attitudes and the tolerance of differences that characterized on-line groups. The new technologies open new horizons and cogni-tive functions.
Composi o bromatológica, consumo e digestibilidade in vivo de dietas com diferentes níveis de feno de catingueira (Caesalpinea bracteosa), fornecidas para ovinos Morada Nova
Gonzaga Neto Severino,Batista ?ngela Maria Vieira,Carvalho Francisco Fernando Ramos de,Martínez Rafael Leonardo Vargas
Revista Brasileira de Zootecnia , 2001,
Abstract: Com objetivo de determinar o consumo e a digestibilidade in vivo, bem como a composi o química de dietas com níveis crescentes (0, 50 e 100%) de feno de catingueira (FC), utilizaram-se 15 ovinos Morada Nova, durante um período de 22 dias. Foi usado delineamento inteiramente casualizado com três tratamentos e cinco repeti es. O FC apresentou 91,5% de matéria seca (MS), 93,89% de matéria organica (MO), 11,25% de proteína (PB), 4,31% de extrato etéreo (EE), 45,47% de fibra em detergente neutro (FDN), 37,08% de fibra em detergente ácido (FDA), 8,39% de hemicelulose (HE), 24,37% de celulose (CE), 12,52% de lignina e 6,30% de tanino condensado. Os consumos de MO e MS, em g/dia, g/kg0,75 e %PV; energia bruta (EB), em kcal/kg/dia e kcal/kg0,75; e dos componentes da parede celular foram reduzidos linearmente pelo aumento de FC na dieta. Os consumos de PB, proteína digestível (PD) e EE aumentaram linearmente com o aumento do FC na dieta. Os coeficientes de digestibilidade da MS, MO, PB e EB das dietas n o foram afetados pela inclus o do FC. No entanto, observou-se redu o linear para os coeficientes de digestibilidade da FDN, FDA, CE e EE e efeito quadrático para o coeficiente de digestibilidade da HE. Os consumos médios de MS e PB verificados nos níveis intermediários de FC atenderam as exigências de manten a dos animais.
