Abstract: rubber band ligation (rb) is considered a minimally invasive method for the treatment of hemorrhoidal disease (hd) and has advantages in relation to hemorrhoidectomy whereby: simplicity of execution, outpatient realization and no need of anesthesia. it is an effective method, especially in the hd grade ii. however, shows complications, and the most frequents are: anal pain, tenesmus, hematochezia and urinary retention. some studies have shown severe complications as major bleeding that needs blood transfusion. thus, this study evaluated the effectiveness and the morbidity of the treatment of hd by the method of rb. it was a prospective study with 59 patients. five (8,5%) patients had hd graded in the first degree, 33 (55,9%) in the second degree and 21 (35,6%) in the third. all patients were submitted to at least two sessions. in the 135 sessions performed, we found: hematochezia in 62 (45.9%), severe pain in 39 (28.9%), vagal symptoms in 10 (7.4%) and pseudostrangulation in 1 (0.7%) session. the cure rate of hemorrhoidal prolapse among patients with hd grade ii was 87.9% and among those with hd grade iii, 76.2%. the treatment of hd by the method of rb proved to be safe and with good cure rate.

Abstract: anus neoplasm accounts for 2 to 4% of colorectal tumors, being more prevalent around the seventh and the eighth decades. females are mostly affected, and the ratio is 3:1. its increased prevalence amongst the population in the past years is probably related to the higher number of people that are affected by sexually transmitted diseases, mainly human papillomavirus (types 16 and 18, mostly) and/or the human immunodeficiency virus. diagnosis is based on clinical findings and anatomopathological tests. the treatment of choice is radiochemotherapy, and the rescue surgery with abdominoperineal resection is used for recurrence and persistence cases. a retrospective and prospective longitudinal observational study was performed with 11 patients diagnosed with anal neoplasm from 2004 to 2010. six (54.5%) were females and five (45.5%) were males. the incidence was higher in the sixth decade, at the mean age of 54.45 years. the most frequent histological type observed was the epidermoid carcinoma, and the most frequent cell differentiation type was the moderately differentiated. chemotharapy associated with radiotherapy was used in 81.9% of the patients, and abdominoperineal resection was necessary as a rescue surgery in 18.2% of the patients.

Abstract: with the advances of videolaparoscopic surgery, this approach had become the treatment of choice for cholelithiasis. however, about 5% to 10% may present common bile duct lithiasis. most surgeons have still difficulties to deal with this situation and do prefer resolve with open surgery or with further endoscopic approach. we present a case of a 60-year-old man, with 18 months history of right upper quadrant pain, weight loss and jaundice. he was referred with diagnostic of pancreatic cancer. laboratory investigation showed increased bilirrubin (10 mg/dl), alkaline phosphatase and ggt. abdominal ultrasound showed atrophic gallbladder with dilated intra and extrahepatic biliary tree. computerized tomography scan disclosed enlarged biliary tree with 3 cm stone in the distal common bile duct. the patient underwent a laparoscopic cholecystectomy followed by choledochotomy and retrieval of the large stone. a latero-lateral choledochoduodenum anastomosis was then performed to decompress the biliary tree. the patient had an uneventful recovery being discharged at the 6th postoperative day. laparoscopic management of choledocholithiasis is feasible in many patients, specially those with dilated biliary tree. the retrieval of stones may be followed by biliary drainage with t-tube. in some elderly patients with chronically dilated common bile duct, as in the present case, a choledochoduodenal anastomosis is the procedure of choice.

Abstract: pancreatic cancer is most often diagnosed too late for curative resection. therefore most of patients with pancreatic cancer are only submitted to palliative procedures. from those submitted to biliary bypass alone about 30 % need treatment for gastric obstruction at some point of the follow up. surgical techniques for gastroenterostomy currently in use carry themselves delaying in the gastric emptying mechanisms and circulus vitiosus through the non obstructed duodenum. the objetive of this paper is to describe a new technique devised to avoid those problems and to improve the functional results of prophylatic gastroenterostomy. this was accomplished by a gastrojejunostomy in the upper body of the stomach and constructing the jejunal loop in a braun fashion, whose afferent loop is blocked. the main features of this technique are the position of the gastroenterostomy with a low distubance of gastric motility and the construction of the jejunal loop in order to avoid the circulus vomiting. nineteen patients were consecutively submitted to this procedure and no post operative complications were observed. nasogastric tube was taken off in about three days and oral feeding resumed the next day. vomits were not observed neither in the early post operative period nor in the long term follow up. this newly designed type of reconstruction is a effective gastric beypass and avoids the problem of food reentry.

Abstract: Plasma citrulline has been used as a marker of intestinal dysfunction because critically ill patients have an acute reduction of enterocyte mass with a reduction in citrulline synthesis. However, the influence of renal failure on plasma citrulline levels must be re-evaluated [1]. Circulating intestinal fatty acid binding protein (I-FABP or FABP6) has been found to be an early marker of intestinal necrosis after aortic surgery [2], after Pringle maneuver in liver surgery [3] and in acute pancreatitis [4]. The aim of this study was to evaluate the value of circulating fatty acid binding protein in the evaluation of intestinal failure in critically ill patients.Plasma I-FABP concentrations were measured in blood samples from 72 critically ill patients admitted to the University of S?o Paulo Department of Emergency Medicine and from 10 healthy controls. Patients comprised 28 critically ill non-infected patients, 13 patients with severe sepsis, 24 patients with septic shock and five patients recovering from septic shock (48 hours without vasopressors). The prevalent sources of infection were pulmonary, urinary tract and catheter-related. The project was approved by the hospital ethic committee and the patients signed informed consent.We observed a significant elevation of serum levels of I-FABP in patients with septic shock when compared with healthy controls (Figure 1).The intestinal functions are complex and comprise not only nutrient digestion and absorption but also a defensive action as an immunological and physical barrier to the external environment. Damage in this complex architecture may lead to increased intestinal permeability and bacterial translocation. Intestinal dysfunction in critically ill patients is difficult to evaluate and is probably common, despite underestimation. I-FABP is a 15 kDa protein located at the tips of intestinal mucosal villi and is usually undetected in the plasma circulation [5]. Intestinal ischemia even for a short period of time is

Abstract: Paciente com história de 18 meses de emagrecimento e icterícia foi encaminhado ao Servi o de Cirurgia Abdominal do Hospital do Cancer, S o Paulo, SP., com hipótese diagnóstica de cancer de cabe a de pancreas. Exames laboratoriais mostraram eleva o de bilirrubinas e de enzimas canaliculares. Ultra-sonografia abdominal revelou dilata o de via biliar intra e extra-hepática. Tomografia computadorizada mostrou árvore biliar dilatada com presen a de cálculo de cerca de 3 cm em colédoco distal. O paciente foi submetido a colecistectomia com coledocotomia, retirada do cálculo e anastomose colédoco-duodenal por laparoscopia. Evoluiu sem intercorrências, recebendo alta no sexto dia de pós-operatório. Conclui-se que o tratamento laparoscópico da coledocolitíase é factível em alguns pacientes, especialmente naqueles com dilata o de via biliar. A retirada de cálculos deve ser seguida de procedimento de drenagem da via biliar com dreno de Kehr. Em alguns pacientes com colédoco cronicamente dilatado, como o do presente caso, a anastomose colédoco-duodenal é o procedimento de escolha.

Abstract: in recent years, the number of information sources offered on the web has grown tremedously. support for accessing these information sources has mostly been concentrated on browsing and search tools. digital libraries and web directories constitute important initiatives to improve information access, creating and organizing document collections hierarchically, according to different criteria. search tools, on the other hand, offer a more comprehensive coverage of resources, using robot-based services to collect and index documents, that can be latter accessed using information retrieval techniques. however, technologies applied to search mechanisms on the web still offer little support to manage document collections, as the association between these documents cannot be explicitly identified, neither by their formats nor by their types. this paper presents a formal structure for organizing and describing collections and their documents on the web. it is based on a metadata conceptual model which explores relationships between information resources at different levels of granularity. to validate this model, a prototype has been implemented using both a semi-structured and an object-relational database (db) approach.

Abstract: The aim of this study was to evaluate the use of a prostaglandin F2α analogue (PGF2α) and oestradiol benzo-ate (ODB) in estrus synchronization programs. A hundred and eighty five non-lactating females divided in 4 groups were used. G1 (44) and G2 (46) received two applications of PGF2α (D0 and D11) and G3 (26) and G4 (37) received one application after 5 days of estrous detection. G1 and G3 also received a 1 mg ODB application 48 hours after the PGF2α. The pregnancy rate at AI was 42,2% for G1, 47,8% for G2, 32,1% for G3 e 57,6% for G4 (p>0,05) and of 38,4% and 51,4% for animals submitted to FTAI and estrous detection, respectively (p>0,05). This results show that pregnancy rates of females fixed time inseminated didn’t differ of that inseminated after estrus detection. Key-words: Beef cattle, estrus synchronization, fixed time artificial insemination, prostaglandin. O objetivo deste estudo foi avaliar o emprego de um análogo da prostaglandina F2α (PGF2α) em associa o ao benzoato de estradiol (BE) em programas de sincroniza o de cios. Utilizaram-se 185 fêmeas n o-lactantes divididas em quatro grupos. O G1 (44) e o G2 (46) receberam duas aplica es de PGF2α (D0 e D11) e os animais do G3 (26) e G4 (37) uma aplica o de PGF2α, após cinco dias de detec o de cio. O G1 e o G3 receberam 1mg de BE 48 horas após a PGF2α. A taxa de prenhez na IA foi de 42,2% no G1, 47,8% no G2, 32,1% no G3 e 57,6% no G4 (p>0,05) e de 38,4% e 51,4% para animais submetidos à IATF e à detec o de cio, respectivamente (p>0,05). Notou-se que a taxa de prenhez nas fêmeas inseminadas em tempo-fixo n o diferiu daquelas que foram inseminadas após a detec o de cio. Palavras-chaves: Bovinos de corte, insemina o artificial em tempo fixo, prostaglandina, sincroniza o de cios.

Abstract: the microleakage behavior of two hybrid glass ionomer cements used as restorative materials (variglass/caulk dentsply and vitremer/3m) was compared. separate class ii cavities were prepared on the mesial and distal aspects of thirteen extracted premolars. one restoration of each material was placed on every tooth. the cervical margins of the restorations were left one millimeter below the cementoenamel junction. thermocycling was conduced in a 0.5% basic fuchsin solution. the teeth were washed and sectioned for microleakage analysis under a dissecting microscope. none of the materials tested were able to inhibit dye penetration at the cervical margin. vitremer/3m was more effective than variglass/caulk dentsply in reducing microleakage.
