Abstract: CASUíSTICA E MéTODOS: Analisamos, retrospectivamente, o índice de mortalidade a médio prazo de 113 doentes portadores de insuficiência mitral, diagnosticados clínica e ecocardiograficamente, e submetidos a tratamento clínico ou cirúrgico. A idade dos pacientes variou de 29 a 67 anos, com média de 47± 4,3 anos, sendo 81 (71,7%) doentes do sexo feminino. De acordo com a classifica o de NYHA, 51 (45,1%) doentes encontravam-se em classe funcional I, 24 (21,2%) em classe II, 21 (18,6%) em classe III e 17 (15,1%) em classe IV. RESULTADOS: Após 4 anos, observamos que o taxa de mortalidade global foi de 21,2%. Todos os 75 (66,4%) doentes que se encontravam em classe funcional I e II receberam apenas tratamento clínico e apresentaram taxa de mortalidade de 12%. Dos 38 pacientes que se encontravam em classe funcional III e IV, 18 (47,4%) foram submetidos a tratamento cirúrgico e apresentaram taxa de mortalidade de 22,2%, sendo 5,5% intra-hospitalar e 16,7% no período de 4 anos. Os 20 (52,6%) doentes que recusaram a opera o apresentavam condi es clínicas semelhantes aos operados e foram submetidos a tratamento clínico, havendo índice de mortalidade de 55%. CONCLUS O: Concluímos que a insuficiência mitral apresenta alto índice de mortalidade e que o tratamento cirúrgico para os doentes que se encontram em classe funcional III e IV da NYHA apresenta menor índice de mortalidade a médio prazo quando comparado ao tratamento clínico, devendo ser indicado sempre quando possível.

Revista Brasileira de Cirurgia Cardiovascular , 2001,
Abstract: A endocardite infecciosa (EI) acometendo próteses valvares é uma complica o freqüente, sendo tratada geralmente com cirurgia, devido ao seu difícil controle clínico e má resposta à antibioticoterapia. Este relato descreve o caso de uma paciente com EI, acometendo simultaneamente as biopróteses aórtica (Ao) e mitral (Mi) após vinte e quatro meses de cirurgia de implantes valvares, submetida a tratamento cirúrgico conservador, e com resultado favorável. Discutem-se as vantagens deste procedimento em situa es específicas.

Abstract: a 65-year-old man, presented with weight loss, dyspnea and recurrent pleural effusion. cardiac evaluation showed a (3/6) diastolic rumble at the apex and accentuated 1st heart sound. echocardiogram evaluation and hemodynamic study revealed a large mass within the left atrium (la), suggesting a myxoma and pulmonary hypertension. open heart surgery was performed and a large la tumor excised, histopathology confirmed the diagnostic of myxoma. pleural effusion has been a very rare manifestation of cardiac myxoma, that sometimes presents unspecific signs only and symptoms of chronic inflammatory disease.
Biaxial Constitutive Model of Active Coronary Media Based on Microstructural Information  [PDF]

Engineering (ENG) , 2013, DOI: 10.4236/eng.2013.510B069
Abstract:

Detailed morphological data of vascular smooth muscle cells (VSMC) of coronary arteries were limited. The present study was to quantify dimensions and orientation of swine coronary VSMC and to develop a micro-structural constitutive model of active media. It was found that geometrical parameters of VSMC (length, width, spatial aspect ratio, and orientation) follow normal distributions, and VSMCs orientate towards the circumferential direction of vessels with oblique and symmetrical angles. A micro-structural model of media layer was developed to accurately predict biaxial active responses of coronary arterial media, based on experimental measurements. The present morphological data base and micro-structural model lead to a better understanding of biomechanics of muscular vessels.

Student facility with ratio and proportion: Mapping the reasoning space in introductory physics
Andrew Boudreaux,Stephen Kanim,Suzanne Brahmia
Physics , 2015,
Abstract: Six specific modes of reasoning about ratio and proportion have been delineated as a means of operationalizing expert practice. These modes stem from consideration of how physicists reason in context, are informed by prior work in physics and mathematics education, and have grain size matched to the steps in reasoning needed to solve problems commonly used in physics instruction. A suite of assessment questions has been developed and validated to probe student facility with the reasoning modes. Responses to open-ended and multiple-choice versions of the assessment questions have been collected from more than 3000 students at Western Washington University, Rutgers University, and New Mexico State University. Results have been used to identify specific reasoning difficulties, to document differences in performance between student populations, and to explore the effect of question context on student reasoning. We find that students enrolled in university physics courses have difficulty interpreting and applying ratios in context, and in many cases lack facility with the reasoning underlying basic arithmetic operations of division and multiplication.
Evaluation of the Photostability and Photodynamic Efficacy of Rose Bengal Loaded in Multivesicular Liposomes
M Fadel, K Kassab
Tropical Journal of Pharmaceutical Research , 2011,
Abstract: Purpose: Rose Bengal (RB) is a potential photodynamic sensitizer in anticancer therapy. The purpose of this study was to prepare multivesicular liposomes (MVL) loaded with RB to enhance its photostability and intracellulaer photodynamic efficacy. Methods: Four MVL-RB formulations were prepared by reverse phase evaporation technique using a double emulsion method. The photostability of RB in phosphate buffer and in MVL was studied by monitoring the change in its absorption spectra at different time points following photoirradiation at 550 nm. Photodynamic cytotoxicity, intracellular uptake and localization of the most photostable MVL-RB were studied on baby hamster kidney fibroblasts to evaluate its photodynamic efficacy, compared with free RB. Results: MVL-RB demonstrated significantly slower photodegradation rates with 10-fold extended halflife compared with free RB in buffer (p < 0.05). The degradation followed pseudo first order kinetics. Photodynamic cytotoxicity studies revealed that MVL-RB increased cell mortality by 1.6 - 2.5-fold, compared to free RB, and this could be attributed to its enhanced intracellular uptake and different localization pattern in the cell, in addition to increased photostability. Conclusion: Loading RB in MVL is a promising approach to improve the photodynamic efficacy of RB, by enhancing its photostability and delivery into cells.

Abstract: ft tissue grafting to improve implant esthetics Case report (6113) Total Article Views Authors: Moawia M Kassab Published Date September 2010 Volume 2010:2 Pages 101 - 107 DOI: http://dx.doi.org/10.2147/CCIDE.S13478 Moawia M Kassab Division of Periodontics, Marquette University, School of Dentistry, Milwaukee, WI, USA Abstract: Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received three soft tissue grafting procedures to augment the gingival tissue. The first surgery included a connective tissue graft to increase the width of the keratinized gingival tissue. The second surgery included the use of autografting (connective tissue graft) to coronally position the soft tissue and achieve implant coverage. The third and final surgery included the use of allografting material Alloderm to increase and mask the implant from showing through the gingiva. Healing period was uneventful for the patient. After three surgical procedures, it appears that soft tissue grafting has increased the width and height of the gingiva surrounding the implant. The accomplished thickness of gingival tissue appeared to mask the showing of implant threads through the gingival tissue and allowed for achieving the desired esthetic that the patient desired. The aim of the study is to present a clinical case with soft tissue grafting procedures.
