Objective: To determine the occurrence of hepatopulmonary syndrome (HPS) in patients with cirrhosis who are candidates for liver transplantation; to compare demographic, clinical, laboratory, and spirometric characteristics, as well as echocardiography results, arterial blood gas analysis, and severity of liver disease between the groups of patients with and without HPS; and to describe the occurrence of HPS in the subgroup of patients with cirrhosis and schistosomiasis mansoni (mixed liver disease). Methods: Between January and November of 2007, we evaluated 44 patients under treatment at the Liver Transplant Outpatient Clinic of the Federal University of Pernambuco Hospital das Clinicas, in the city of Recife, Brazil. The diagnostic criteria for HPS were intrapulmonary vascular dilatation, identified by transthoracic echocardiography, and an alveolar-arterial oxygen tension difference ≥ 15 mmHg or a PaO 2 < 80 mmHg. Results: The mean age of the patients was 52 years, and 31 patients (70%) were males. The most common cause of cirrhosis was alcohol use. Schistosomiasis was present in 28 patients (64%). Of the 44 patients, 20 (45.5%) were diagnosed with HPS. No significant differences were found between those patients and the patients without HPS in terms of any of the characteristics studied. Of the 28 patients with cirrhosis and schistosomiasis, 10 (35.7%) were diagnosed with HPS. Conclusions: In the population studied, HPS was highly prevalent and did not correlate with any of the variables analyzed.
RESUMEN Introduccion: El sindrome de tunel del carpo afecta el 1% de la poblacion, siendo la neuropatia por compresion mas frecuente, la liberacion endoscopica es una tecnica que presenta buenos resultados, aunque no esta exenta de complicaciones. Objetivo: El objetivo del estudio es determinar la prevalencia de complicaciones asociadas en una experiencia de 5 anos. Metodologia: Estudio de corte transversal en pacientes con diagnostico del tunel del carpo sometidos a liberacion endoscopica en un periodo de 5 anos, donde se documento todas las complicaciones neurologicas, vasculares e infeccion. Resultados: Se incluyeron 175 manos en 139 pacientes con un promedio de edad de 52 anos de edad; el 89.2% de los casos se presentaron en mujeres. Las comorbilidades encontradas fueron: hipertension arterial 31.6%, hipotiroidismo 29.5%, diabetes 5%, y consumo de cigarrillo 11%. La prevalencia de complicaciones fue del 5.7% (10 casos), de las cuales la lesion neurologica fue del 0.6% clasificada como neuropraxia del nervio cubital, 1.7% presentaron hematomas que resolvieron sin cirugia y 3.4% presentaron infeccion que resolvieron con manejo antibiotico y curaciones. Todas las complicaciones presentaron una recuperacion satisfactoria. El 99% de los pacientes presentaron resolucion de los sintomas. Conclusiones: La tecnica de liberacion endoscopica del tunel del carpo es una tecnica segura, en donde se encontro un porcentaje bajo de complicaciones siendo comparables a otras series.Palabras claves: Endoscopia, Sindrome de tunel carpiano, complicaciones.
Introduction - Roux-en-Y gastric bypass may result in stenosis of the gastrojejunal anastomosis. There is currently no well-defined management protocol for this complication. Aim - Through systematic review, to analyze the results of endoscopic dilation in patients with stenosis, including complication and success rates. Methods - The PubMed database was searched for relevant studies published each year from 1988 to 2010, and 23 studies were identified for analysis. Only papers describing the treatment of anastomotic stricture after Roux-en-Y gastric bypass were included, and case reports featuring less than three patients were excluded. Results - The mean age of the trial populations was 42.3 years and mean preoperative body mass index was 48.8 kg/m². A total of 1,298 procedures were undertaken in 760 patients (81% female), performing 1.7 dilations per patient. Through-the-scope balloons were used in 16 studies (69.5%) and Savary-Gilliard bougies in four. Only 2% of patients required surgical revision after dilation; the reported complication rate was 2.5% (n=19). Annual success rate was greater than 98% each year from 1992 to 2010, except for a 73% success rate in 2004. Seven studies reported complications, being perforation the most common, reported in 14 patients (1.82%) and requiring immediate operation in two patients. Other complications were also reported: one esophageal hematoma, one Mallory-Weiss tear, one case of severe nausea and vomiting, and two cases of severe abdominal pain. Conclusion - Endoscopic treatment of stenosis is safe and effective; however, further high-quality randomized controlled trials should be conducted to confirm these findings. ABCDDV/885
Over the last century there has been a considerable increase in human longevity and this made a large number of people to reach a critical age for development of several diseases. As a result of this increase in life expectancy health issues related, some examples are hypercholesterolemia, hyperglycemia and increased levels of blood urea. This paper presents a portable and low cost system using Artificial Neural Networks to blood metabolites identification. The system developed is based in amperometric biosensors and is able to perform the identification of glucose, cholesterol and urea concentrations in the blood. The main goals of this system is: the identification of three types of blood metabolites with their concentrations, the low cost of the entire system and the reuse capability of the biosensor.
ABSTRACTBackground: To analyze the results of the incidence of wound infection under 3 different antibiotics regiments. Methods:Between January, 1999 and December, 2004, 716 bariatric surgeries had been performed using the technique proposed byFobi/Capella. Three groups of patients had been compared, according to the antibiotic prophylaxys regimen: Group I: (n=185)ampicillin/sulbactam, 3g in two doses; Group II (n=280): ceftriaxone, 1g (single dose); and Group III: (n=251) ertapenem, 1g (single dose). Results: Our results demonstrate a rate of wound infection of 3.78% with ampicilina-sulbactam, 6.81% withceftriaxona and 1.99% in the ertapenem group. There was no significant differences between ampicilina/sulbactam or ceftriaxonain relation to the incidence of wound infection. However, there was a statistically significant difference between Group II(Ceftriaxona) and Group III (Ertapenem). Conclusion: The use of ertapenem as the antibiotic prophylaxis for the surgical ofmorbid obesity was associated to a lower incidence of wound infection than with the use of ceftriaxone, while being similar tha nampicillin/sulbactam.Key words: Surgical wound infection; Bariatric surgery; Infection; Antibiotic prophylaxis; Gastroplasty; Obesity, morbid.

ABCD Arq Bras Cir Dig. 2008;21(2):73-6RESUMO – Racional – A execucao de bypass gastrico laparoscopico em hospital universitario publico tem sido dificil devido ao elevado custo dos grampeadores cirurgicos que prejudica o treinamento de medicos residentes e tem motivado a busca por tecnicas alternativas, de baixo custo, mantendo a eficacia. Objetivo – Apresentar a viabilidade de um metodo com menor uso de suturas mecânicas. Metodos – Foram operados 63 pacientes em 2 hospitais universitarios, sendo 12 homens e 51 mulheres (81%), com media de 33,5 anos de idade e IMC medio de 43. Aplicou-se a seguinte padronizacao tecnica: Seccao da alca com bisturi eletrico a 50 cm do ângulo duodeno-jejunal, anastomose termino-lateral, passagem da alca retrocolica e retrogastrica, confeccao da parede lateral da bolsa gastrica com 1 carga azul de 45 e outra de 60 mm apos a seccao horizontal com bisturi eletrico, sutura do estomago excluso e anastomose gastrojejunal. As anastomoses foram manuais e continuas com fio absorvivel. Re-sultados – O tempo operatorio medio foi de 5,5 horas. As complicacoes precoces foram: fistula no ângulo de esofago-gastrico (1,6%), estenose (1,6%) e fistula na anastomose gastrojejunal (1,6%) e torcao da anastomose intestinal (1,6%). A estenose foi tratada por dilatacao endoscopica e as outras complicacoes atraves de 3 re-operacoes (2 laparoscopicas e 1 laparotomica). O tempo de internacao variou de 2 a 20 dias, com media de 4 dias, nao havendo obito. Conclusao – Este metodo e viavel e com baixo custo operacional; todavia, e complexo e requer habilidade principalmente em suturas laparoscopicas.
ABSTRACT: The Syndrome of Williams is a rare genetic illness, attributed the deletion of the gene of the elastin in chromosome7. It is characterized by aortic stenosis, bladder diverticula’s, constipation, light mental retardation, dysmorphic facies, we aknessof the wall of the bladder and colon that they lead to the sprouting of diverticula. A case of acute diverticulitis in patient of 18 yearsis told, the result of the clinical treatment during 5 years and the differential diagnosis of acute abdomen in this illness. Theindication of elective colectomy is argued, considering the unfamiliarity of the natural history of the diverticulitis in thesyndrome.Key words: Diverticulitis, acute abdomen, adolescent, Williams Syndrome.
