As hérnias perineais representam uma patologia comum na área da cirurgia de tecidos moles em pequenos animais, mais frequentemente em cães, machos, não castrados com idade superior a 5 anos. A sua apresentação clínica, na grande maioria das vezes, não requer intervenção cirúrgica urgente para a sua resolução, no entanto, em situações mais severas que incluam encarceramento de órgãos como a bexiga e/ou próstata, esta pode ser considerada uma urgência. O presente estudo teve como objectivo abordar os factores relevantes para o conhecimento da hérnia perineal, como os sinais clínicos, a incidência, os métodos de diagnóstico, dando ênfase aos tratamentos cirúrgicos, por ser uma patologia com elevado índice de recidivas e complicações pós-cirúrgicas. Para tal, foi estudada uma amostra de 26 pacientes de espécie canina com idades compreendidas entre os 5 e os 13 anos de idade, com hérnia perineal diagnosticada, em alguns Hospitais na zona de Lisboa. Na amostra em estudo, obteve-se uma prevalência de 96,2% de machos sendo que destes 25 machos apenas 1 era castrado, obtendo-se uma prevalência de 4%. Existiu neste estudo uma grande variação de raças sendo que houve uma maior predominância de animais sem raça definida com 8 casos (30...

FUNDAMENTO: A transposição corrigida das grandes artérias frequentemente evolui com disfunção ventricular direita. O preparo ventricular para a correção anatômica em pacientes adultos apresenta resultados desapontadores. OBJETIVO: Analisar a hipertrofia do ventrículo direito (VD) induzida por dois tipos de bandagem pulmonar (BP), convencional e intermitente em animais adultos. MÉTODOS: Dezenove cabras adultas foram divididas em três grupos: Convencional (seis animais), Intermitente (seis animais) e Controle (sete animais). O grupo Convencional foi submetido à BP fixa com fita cardíaca, enquanto no grupo Intermitente foi usado dispositivo de BP ajustável, que gerava sobrecarga sistólica por 12 horas, alternada com 12 horas de descanso do VD. As pressões de VD, tronco pulmonar e aorta foram medidas durante todo o estudo. Ecocardiograma foi realizado semanalmente. Após quatro semanas, os animais foram eutanasiados para avaliação morfológica dos ventrículos. O grupo Controle foi submetido a eutanásia para análise em condições basais. RESULTADOS: A sobrecarga pressórica foi menor no grupo Intermitente (p=0,001), comparada ao grupo Convencional. Houve aumento na espessura do VD do grupo Intermitente, medida pelo ecocardiograma...

OBJETIVO: A bandagem ajustável do tronco pulmonar (TP) pode proporcionar treinamento ventricular mais fisiológico para cirurgia de Jatene em dois estágios. Este estudo experimental analisa a hipertrofia aguda (96 horas) do ventrículo direito (VD) submetido à sobrecarga sistólica intermitente. MÉTODOS: Cinco grupos de sete cabritos jovens foram dispostos conforme o tempo de sobrecarga sistólica do VD (0, 24, 48, 72 e 96 horas). O grupo zero hora funcionou como grupo controle. Avaliações ecocardiográficas e hemodinâmicas foram feitas diariamente. Os animais foram sacrificados para avaliação do conteúdo de água e pesagem das massas cardíacas. RESULTADOS: Houve aumento da espessura do VD a partir de 48 horas de treinamento (p<0,05) e rebaixamento da fração de ejeção do VD, com dilatação importante desta câmara nas primeiras 24 horas do protocolo, recuperando-se posteriormente. Houve aumento da relação volume/massa nas primeiras 24 horas do protocolo, em relação ao momento 96 horas (p=0,003). A massa do VD apresentou aumento de 104,7% no grupo 96 horas em relação ao controle. Não houve diferença quanto ao conteúdo de água do VD. A média diária de aumento da massa do VD foi de 21,6% ± 26,8%. A taxa de ganho de massa muscular do VD para todo o período de estudo foi de 0...

INTRODUÇÃO: Para os pacientes portadores de transposição das grandes artérias que perderam a chance da cirurgia de Jatene nas primeiras semanas de vida, indica-se realizar o preparo ventricular através da bandagem do tronco pulmonar (BTP), objetivando causar aumento na massa miocárdica. Entretanto, com o tempo, a câmara hipertrofiada pode apresentar disfunção contrátil; portanto, é importante conhecer a qualidade do tecido preparado, uma vez que já se sabe que tanto os miocardiócitos (MCD) quanto as células do interstício e vasos (I/V) são capazes de proliferar após o período neonatal. Baseando-se no condicionamento físico de atletas e considerando-se que os músculos cardíaco e esquelético são ambos estriados, postula-se a hipótese de que o tipo de preparo ventricular possa influenciar nas características do miocárdio treinado. OBJETIVOS: Identificar o tipo de mecanismo adaptativo (hipertrofia/hiperplasia) envolvido no preparo rápido do ventrículo pulmonar submetido à sobrecarga de pressão por meio de BTP, através da análise dos MCD e células do I/V, verificando se existem diferenças em relação ao tipo de treinamento (contínuo x intermitente) em comparação com os controles. MÉTODOS: Foram estudados experimentalmente 21 cabritos após o período neonatal...

A paralisia facial é uma patologia de etiologia ampla, com prejuízos múltiplos e severos aos indivíduos afetados. Dentre os tratamentos cirúrgicos atualmente propostos a reanimação facial com retalho de músculo temporal se posiciona intermediariamente no espectro de complexidade. Neste estudo objetivou-se a identificação dos resultados com seu uso em nossa disciplina, pela revisão dos prontuários dos pacientes acometidos de tal patologia nos últimos 17 anos. Dos 152 prontuários avaliados, 93 se enquadravam nos critérios de inclusão. Destes, 36 casos com paralisia facial periférica completa foram passíveis de estudo, correspondendo a 39% dos casos de transposição. Os resultados foram uma predominância de pacientes do sexo feminino (26) em relação ao sexo masculino (10). A reanimação conjunta de pálpebra e boca com a transposição do músculo temporal correspondeu a 16 casos; pálpebra a 12 casos; e boca a 8 casos. Nos casos com transplante muscular microcirúrgico, o músculo grácil foi utilizado. A média de procedimentos ancilares das pacientes do sexo feminino foi superior a do sexo masculino. Alterações da técnica da transposição do músculo temporal foram observadas em casos a partir de 2001, com a neurotização muscular por enxerto transfacial de nervo sural em 9 casos. A técnica utilizada em nosso serviço se baseia no retalho de Gillies...

Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Pós-graduação em Bases Gerais da Cirurgia - FMB; Várias técnicas são utilizadas para o tratamento da paralisia facial, entre elas o enxerto de nervo transfacial e a transposição muscular. Estas técnicas foram associadas utilizando neurorrafia término-terminal (NTT) para tornar o músculo temporal duplamente inervado, porém, a secção de nervos saudáveis pode levar à atrofia ou enfraquecimento muscular. Os objetivos deste trabalho foram analisar a ocorrência da dupla inervação muscular através da neurorrafia término-lateral (NTL), avaliar a imediata inervação muscular através da NTL, evitando atrofia muscular e avaliar a ocorrência de degeneração Walleriana no segmento distal à NTL no nervo receptor. Foram utilizados 140 ratos Wistar divididos em sete grupos experimentais. O G1 foi o grupo controle de normalidade e o G2 o controle de desnervação. Em 80 ratos foi realizada a dupla inervação muscular (DIM) suturando o segmento proximal do nervo tibial (NT) na lateral intacta do nervo fibular comum (NFC). Estes ratos foram divididos em quatro grupos: G3 no qual os animais foram sacrificados após 120 dias; G4 onde 120 dias após a realização da DIM...

Several surgical procedures have been proposed through the years for the treatment of facial paralysis. The multiplicity and diversity of techniques portray the complexity and challenge represented by this pathology. Two basic dynamic options are available: -Reconstruction of nerve continuity through direct micro suture, with interposition grafts or nerve transpositions. -Regional muscular transposition, most often using the temporalis. Facial reanimation with the temporalis transfer has withstood the test of time and still is a reference technique. In a few weeks, good results can be obtained with a single and rather simple surgical procedure. Functional free flaps have been used with increasing frequency in the last two decades, most often combining a cross-facial nerve graft followed by a gracilis free flap nine months later. With this method there is a potential for restoration of spontaneous facial mimetic function. Apparently there is a limit in microsurgical technique and expertise beyond which there is no clear improvement in nerve regeneration. Current research is now actively studying and identifying nerve growth factors and pharmacological agents that might have an important and complementary role in the near future.

We have previously reported isolated cases of anatomical and functional closure of ventricular septal defects in tricuspid atresia. To study this phenomenon further, clinical, angiographic, and pathological findings in 20 consecutive cases of tricuspid atresia were reviewed. Sixteen cases were found to have normally related great arteries (type I) and 4 had transposition (type II). In 6 of these patients there was evidence of closure of a ventricular septal defect; in 3 this was complete and in the other 3, partial. Five of these ventricular septal defect closures occurred in type I patients and one among type II. Increasing cyanosis and polycythaemia and/or disappearance of a previously heard murmur were observed in all patients; these signs are more conspicuous in complete closure than in partial. The incidence of closure of ventricular septal defect in tricuspid atresia is 38 per cent and approximates to the incidence of spontaneous closure of isolated ventricular septal defects. Progressive muscular "encroachment" of the margins of ventricular septal defects with subsequent fibrosis and covering by endocardial proliferation is the most likely mechanism of closure in tricuspid atresia. The factors initiating the closure of ventricular septal defect remain unknown...

Approximately 17% of the human genome is comprised of long interspersed nuclear element 1 (LINE-1, L1) non-LTR retrotransposons. L1 retrotransposition is known to be the cause of several genetic diseases, such as hemophilia A, Duchene muscular dystrophy, and so on. The L1 retroelements are also able to cause colon cancer, suggesting that L1 transposition could occur not only in germ cells, but also in somatic cells if innate immunity would not function appropriately. The mechanisms of L1 transposition restriction in the normal cells, however, are not fully defined. We here show that antiretroviral innate proteins, human APOBEC3 (hA3) family members, from hA3A to hA3H, differentially reduce the level of L1 retrotransposition that does not correlate either with antiviral activity against Vif-deficient HIV-1 and murine leukemia virus, or with patterns of subcellular localization. Importantly, hA3G protein inhibits L1 retrotransposition, in striking contrast to the recent reports. Inhibitory effect of hA3 family members on L1 transposition might not be due to deaminase activity, but due to novel mechanism(s). Thus, we conclude that all hA3 proteins act to differentially suppress uncontrolled transposition of L1 elements.

Plexogenic pulmonary arteriopathy runs a more progressive course in transposition of the great arteries with pulmonary hypertension (TGA) and in primary pulmonary hypertension (PPH) than, for instance, in isolated ventricular septal defect (VSD). Fibrinoid necrosis and plexiform lesions occur more often and at a younger age in TGA and PPH than in VSD. A morphometric study in 18 patients with VSD, 14 patients with TGA, 38 patients with PPH, and 21 controls showed that the media of muscular pulmonary arteries is significantly thicker in VSD than in TGA or PPH, with the sole exception of very young children with PPH. This difference in medial thickness is apparent at any level of pulmonary arterial pressure. Conversely, the more advanced pulmonary vascular lesions were particularly prominent in TGA and PPH. It is likely that medial hypertrophy, at least to a certain extent, protects the pulmonary arteries from the development of more ominous vascular alterations.

Of 18,000 children with organic heart disease evaluated at The Hospital for Sick Children, Toronto between 1940 and 1971, 33 died suddenly and unexpectedly between 1 and 21 years of age. Nine had discrete obstruction of the left ventricular outflow tract and five had muscular narrowing of the left ventricular outflow tract and five had muscular narrowing of the left ventricular outflow tract. Pulmonary vascular disease caused seven sudden deaths, and arrhythmias (usually due to atrioventricular block) caused seven more. Of the five other children who died suddenly three had transposition of the great arteries, one had a complex cyanotic heart defect and one had an anomalous course of the left coronary artery, which originated from the right sinus of Valsalva. With earlier investigation of aortic stenosis, earlier closure of ventricular septal defect to avoid pulmonary vascular disease, better design of artificial pacemakers and better investigation of patients with angina, many of these deaths will be avoided in the future.

Associations between ambient air pollution levels during weeks 3–7 of pregnancy and risks of cardiovascular malformations were investigated among the cohort of pregnancies reaching at least 20 weeks’ gestation that were conceived during January 1, 1986–March 12, 2003, in Atlanta, Georgia. Surveillance records obtained from the Metropolitan Atlanta Congenital Defects Program, which conducts active, population-based surveillance on this cohort, were reviewed to classify cardiovascular malformations. Ambient 8-hour maximum ozone and 24-hour average carbon monoxide, nitrogen dioxide, particulate matter with an average aerodynamic diameter of <10 μm (PM10), and sulfur dioxide measurements were obtained from centrally located stationary monitors. Temporal associations between these pollutants and daily risks of secundum atrial septal defect, aortic coarctation, hypoplastic left heart syndrome, patent ductus arteriosus, valvar pulmonary stenosis, tetralogy of Fallot, transposition of the great arteries, muscular ventricular septal defect, perimembranous ventricular septal defect, conotruncal defects, left ventricular outflow tract defect, and right ventricular outflow defect were modeled by using Poisson generalized linear models. A statistically significant association was observed between PM10 and patent ductus arteriosus (for an interquartile range increase in PM10 levels...

Total surgical correction of a Taussig-Bing type double outlet right ventricle (DORV) was successfully performed in a severely cyanotic 3-year-old girl. The malformation was associated with bilateral conus, d-transposition of the great arteries, d-loop, and a subpulmonary ventricular septal defect (VSD) without significant pulmonary stenosis in situs solitus. It was impossible to create a tunnel repair by resecting the markedly hypertrophied muscular conus that separated the aortic valve from the subpulmonary ventricular septal defect. Therefore, the VSD was repaired with a Dacron patch, transforming the double outlet right ventricle into a transposition, after which total correction was achieved by means of a Mustard procedure.

Progressive cyanosis after banding of the pulmonary artery in infancy occurred in a child with transposition of the great arteries and a ventricular septal defect, and a Blalock-Taussig shunt operation had to be performed. At the time of correction a segment of pulmonary artery between the left ventricle and the band was found to be completely occluded so that continuity between the left ventricle and the pulmonary artery could not be restored. A Rastelli type of operation was not feasible as the ventricular septal defect was sited low in the muscular septum. Therefore, in addition to Mustard's operation, a Dacron conduit was inserted from the left ventricle to the main pulmonary artery to relieve the obstruction. Postoperative cardiac catheterization with angiocardiography indicated a satisfactory haemodynamic result. The patient remains well 11 months after the operation. This operation, a left ventricle to pulmonary artery conduit, may be used as an alternative procedure in patients with transposition of the great arteries, intact interventricular septum, and obstruction to the left ventricular outflow, if the obstruction cannot be adequately relieved.

Mediastinitis with graft infection is a serious complication of ascending aorta replacement. We report two cases of graft infection, treated with surgical cleaning, graft preservation and transposition of muscle flaps. A 62 years old male was admitted 34 days after an ascending aortic grafting due to a sternal dehiscence and mediastinitis. Antimicrobial treatment was started and a surgical cleaning performed, leaving an open sternotomy. Three days later, the thoracic cavity was closed with a rectus abdominis muscle flap. After 23 months of follow up, the patient is well and without evidence of infection. A 74 years old male was subjected to an aortic valve and ascending aorta replacement and a myocardial revascularization. In the postoperative period, the patient developed septic signs, and a purulent drainage. A CAT scan showed a liquid collection surrounding the aortic graft. On tW Sixteenth postoperative day, a surgical cleaning was performed and the thorax was closed with the pectoralis major muscle. After 10 months of follow up, the patient is in Good condition and without evidence of infection (Rev Méd Chile 2001; 129: 196-200).

Introduction. We propose our surgical experience and the decisional algorithm we use to select the surgical procedure for the ulnar nerve entrapment at the elbow according to defined parameters. Materials and methods. Between 2005 and 2007, 44 patients were operated according to our algorithm that is based both on clinical parameters, classified through the McGowan scale, and on biological ones (the nervous morphology and the amount of scar around the medial epicondyle). Patients were treated through "modified" in situ simple decompression, subcutaneous and sub muscular transpositions. Results. After an average follow-up of 13.4 months, function improved by one grade in 70% of patients, two grades in 16% and there was no change in 14%. Moreover 84,8% of patients operated through the modified in situ decompression technique reported an excellent outcome. Conclusion. We suggest an algorithm for uniformly treat the patients with cubital tunnel syndrome through a clinical and biological point of view. The modified in situ decompression is a safe and effective treatment for the majority of these patients reducing the risk of redo surgery.
