This disease is cured in various interventional and surgical ways of treatment. Open surgeries according to Palomo and Ivanisevic are considered to be a classical way of treatment of varicocele. However, during two recent decades open surgeries are performed less in relation to wound infections that make 5.8% (Zuckerman et al. 1994) and a rather big number (16%) of recurrence of a disease (Rothman et al. 1981, Cayan et al. 2000, Kass et al. 2001). More simple and minimally invasive ways of treatment of varicocele are being searched. Retrograde sclerotherapy of the veins of the spermatic cord (RS) or embolization is an easier procedure and patients spend less time in hospital. However, these interventions are not available to perform in 15-30% of all cases (Porst et al. 1984, Okuyama et al. 1988, Winkelbauer et al. 1994, Abdulmaaboud et al. 1998), and the frequency of recurrence makes 10-15% (Lenk et al. 1994, Punekar et al. 1996). After the introduction of microsurgical equipment, the veins of the spermatic cord are ligated using...

2	Qualidade de vida e incontinência urinária e fecal: o adolescente em foco Ribeiro de Oliveira, Carina 31 January 2011 (has links) Made available in DSpace on 2014-06-12T23:14:52Z (GMT).

As principais motivações para a escolha do tema desta pesquisa foram: o limitado número de profissionais Estomaterapeutas interessados em atuar na área de incontinência; a escassez de estudos acerca do tema; a reduzida oferta de serviços em saúde especializados, interdisciplinares e voltados ao atendimento de pacientes portadores de incontinências; a precariedade comumente encontrada nesses serviços e que, de um modo geral, não possuem estrutura física adequada, recursos humanos e fomentos suficientes para alicerçar a assistência à saúde desse público. A partir disso sucedeu-se a delimitação do problema e a realização desta pesquisa que está estruturada em duas partes. A primeira consta do artigo Qualidade de vida de adolescentes incontinentes: revisão integrativa da literatura , realizada a partir das bases de dados LILACS, MEDLINE e Cochrane, no período de janeiro de 2001 a março de 2011. Foram utilizados para busca os descritores qualidade de vida, adolescente, criança, estomia e enema, e as palavras MACE (Malone antegrade continence enema), Malone, bexiga e incontinência, cuja seleção da amostra foi composta por oito artigos. Os resultados demonstraram que as pesquisas com adolescentes incontinentes ainda são incipientes e heterogêneas, sendo pouco comuns os estudos que abranjam exclusivamente este público. A segunda parte corresponde ao artigo original Qualidade de vida de adolescentes submetidos à ampliação vesical e à cirurgia de Malone que objetivou descrever a qualidade de vida de adolescentes incontinentes submetidos a estas cirurgias. O estudo descritivo com abordagem quantitativa foi realizado no ambulatório de cirurgia e urologia pediátrica do Hospital Infantil Maria Lucinda, e investigou os adolescentes de 10 a 18 anos com incontinência urinária e/ou fecal, submetidos à ampliação vesical e à cirurgia de Malone, concomitantemente ou não, totalizando 35 participantes. Os dados foram coletados através de entrevista presencial após consentimento do adolescente e de seu responsável, e foram utilizados dois instrumentos: o questionário estruturado sociodemográfico e o questionário genérico autoadministrado de qualidade de vida, o Pediatrics Quality of Life InventotyTM Version 4.0 (PedsQLTM). O banco de dados foi criado no programa EPI-INFO 6.04, bem como as análises estatísticas que foram expressas pelas médias dos escores das dimensões física e psicossocial e escore total. Os resultados mostraram que a qualidade de vida relacionada à saúde dos adolescentes incontinentes, de um modo geral foi positiva e demonstrou que a ampliação vesical e a cirurgia de Malone contribuem para minimizar os efeitos negativos da incontinência urinária e fecal sobre as dimensões física e psicossocial Qualidade de vida Incontinência urinária Incontinência fecal Adolescente Ampliação vesical
3	FE Modelling Of Two Femur Fixation Implants Arsiwala, Ali, Shukla, Vatsal January 2021 (has links) In the pool of women over the age of 50, the likeliness of an atypical fracture increase drastically, partly due to osteoporosis. With a pre-existing implant in the femur bone, inserted due to a prior atypical fracture, treating a later femoral neck fracture is complex and risky. Currently, a fractured femoral diaphysis is treated using an intermedullary nail which is fixed to the femur bone either through the femoral neck (Recon locking method)or through the lesser trochanter (Antegrade locking method). In a study conducted by Bögl et.al. JBJS102.17 (2020), pp. 1486-1494, it is found that the fixation of the intermedullary nail through the femoral neck reduces the risk of future femoral neck fractures. The study also states that more than 50% of the patients with atypical femoral fractures related to bisphosphonate treatment for osteoporosis (within the study sub population) were treated with the Antegrade locking implant. There does not exist much literature that reasons as to how one locking method is showing lesser risk of re-operation as compared to the other. The purpose of this study is to look into the effects these two implants have on the femur bone using the Finite Element Analysis (FEA). The study presented is aimed at comparing the results of the finite element analysis for the Recon implant model (Recon model) and Antegrade implant model (Antegrade model). The femur model without the implants (native bone model) is used to verify material behavior, while the other two are used for the comparison to study the stress-strain distribution, primarily in the neck region. This is a patient specific study, hence the femur bone model is generated using patient Computed Tomography (CT) scans. The bone model was assigned a heterogeneous isotropic material property derived from patient CT data. The finite element (FE) model of the bone was meshed using Hypermesh. The peak loading condition including the muscle forces were applied on the native bone model along with the Recon and the Antegrademodel. While the loading conditions during normal walking cycle were only applied to theRecon and the Antegrade model to compare the impacts of the two implant types. Both loading conditions were simulated by fixing the distal condyle region of the bone. The analysis results show that the Antegrade implant experiences much higher stresses and strains in the neck region as compared to Recon implant. Also, the presence of the intermedullary nail through the femur diaphysis helps to distribute the stresses and strains in the anterior distal diaphysis region of the bone. For the case of no implants, the model showed strains and stresses in the lateral distal region of femoral diaphysis.

A long terme, la défaillance cardiaque, l’hypertension artérielle pulmonaire(HTAP) et l’entéropathie exsudative peuvent mener à l’échec tardif du Fontan.Une mise au point clinique a été realisée en se focalisant secondairement sur les patients adultes.L’intérêt de la cavo bipulmonaire (CBP), étape intermédiaire au Fontan, dans certains cas de retours veineux pulmonaires anormaux totaux a été décrite. Afin d’affiner de futures études cliniques, nous avons discuté de l’intérêt du Brain NatriureticPeptide en post opératoire de Fontan. Nous avons démontré la fiabilité d’une nouvelle technologiede l’oxyme´trie de pouls chez des enfants cyanosés et la non fiabilité d’un nouveau dispositifd’impédancemétrie pour le monitorage non invasif du de´bit cardiaque en comparaison avecun cathéter artériel pulmonaire.Un modèle animal viable et chronique de la CBP a été développé. Il a montré que le flux pulsatileantérograde empêche la formation de fistules artério-veineuses pulmonaires (FAVP), améliorel’hématose et atténue le développement de l’HTAP soutenant cliniquement le maintien de ce fluxlors de la création d’une CBP. Par ailleurs, la perte de pulsatilité, en diminuant le contrainte de cisaillement, entraîne unediminution de l’eNOS synthase et une réponse altérée vaso-relaxante dépendante de l'endothélium artérielle pulmonaire. La micropulsatilité limite ces effets délétères. Ces résultats impliquent desthérapies potentielles contre l’HTAP du Fontan, en maintenant un débit pulmonaire accessoire et la modulation pharmaceutique vaso-relaxante non endothélium-dépendante / The Fontan surgery is a palliative surgery for univentricular congenital heart disease. On the longterm, heart failure, pulmonary arterial hypertension (PAH) and exudative enteropathy may lead tothe Fontan failure.A clinical adjustment has been realized by focusing secondarily on adult patients. The advantage, insome cases of total anomalous pulmonary venous return, of the bidirectional cavopulmonary (BCP),which is an intermediate stage of Fontan, has been described.In order to prepare future clinical studies, we have discussed about Brain Natriuretic Peptide inpostoperative Fontan surgery. We have demonstrated the reliability of a new technology of pulseoxymetry in cyanotic children and the unreliability of a new device of impedance for non-invasivemonitoring of cardiac outpout in comparison with pulmonary arterial catheter.A viable chronic animal model of bidirectional cavo-pulmonary (BCP) has been developed. Itshowed that the antegrade pulsatile flow prevents the formation of pulmonary arteriovenous fistulas(PAVMs) ,improves hematosis and attenuates the development of PAH clinically supporting themaintenance of this flow when creating a BCP.Moreover, the loss of pulsatility while reducing the shear stress causes a decrease in e-NOSsynthase and a dependent vaso-relaxing altered response of the pulmonary arterial endothelium. Themicropulsatility limits these deleterious effects. These results imply potential therapies against thePAH of Fontan surgery, maintaining an accessory pulmonary blood flow and the pharmaceuticalvaso-relaxing non-endothelium dependent modulation.
