Nursing intervention bundle for enteral nutrition in intensive care: a collective construction

Objective The collective construction of a nursing intervention bundle for patients in critical care in the hospital receiving enteral nutrition therapy, supported by evidence-based practice. Method A qualitative convergent-care study with 24 nursing professionals in an intensive care unit of a public hospital in Santa Catarina. Data collection was performed from May to August 2013, with semi-structured interviews and discussion groups. Results Four interventions emerged that constituted the bundle: bedside pH monitoring to confirm the position of the tube; stabilization of the tube; enteric position of the tube; and maintaining the head of the bed elevated at 30° to 45°.
 Conclusion The interventions chosen neither required additional professional workload nor extra charges to the institution, which are identified as improving the adoption of the bundle by nursing professionals at the ICU.

In vitro selection of bacteria with potential for use as probiotics in marine shrimp culture

The objective of this work was to isolate strains of lactic acid bacteria with probiotic potential from the digestive tract of marine shrimp (Litopenaeus vannamei), and to carry out in vitro selection based on multiple characters. The ideotype (ideal proposed strain) was defined by the highest averages for the traits maximum growth velocity, final count of viable cells, and inhibition halo against nine freshwater and marine pathogens, and by the lowest averages for the traits duplication time and resistance of strains to NaCl (1.5 and 3%), pH (6, 8, and 9), and biliary salts (5%). Mahalanobis distance (D²) was estimated among the evaluated strains, and the best ones were those with the shortest distances to the ideotype. Ten bacterial strains were isolated and biochemically identified as Lactobacillus plantarum (3), L. brevis (3), Weissella confusa (2), Lactococcus lactis (1), and L. delbrueckii (1). Lactobacillus plantarum strains showed a wide spectrum of action and the largest inhibition halos against pathogens, both Gram-positive and negative, high growth rate, and tolerance to all evaluated parameters. In relation to ideotype, L. plantarum showed the lowest Mahalanobis (D²) distance, followed by the strains of W. confusa, L. brevis, L. lactis, and L. delbrueckii. Among the analyzed bacterial strains, those of Lactobacillus plantarum have the greatest potential for use as a probiotic for marine shrimp.

Rendu-Osler-Weber syndrome: what radiologists should know. Literature review and three cases report

Rendu-Osler-Weber syndrome or hereditary hemorrhagic telangiectasia is an autosomal dominant vascular disease involving multiple systems whose main pathological change is the presence of abnormal arteriovenous communications. Most common symptoms include skin and mucosal telangiectasias, epistaxis, gastrointestinal, pulmonary and intracerebral bleeding. The key imaging finding is the presence of visceral arteriovenous malformations. The diagnosis is based on clinical criteria and can be confirmed by molecular biology techniques. Treatment includes measures for management of epistaxis, as well as surgical excision, radiotherapy and embolization of arteriovenous malformations, with emphasis on endovascular treatment. The present pictorial essay includes a report of three typical cases of this entity and a literature review.

Portal cholangiopathy: case report

The present report describes the case of a child that after blunt abdominal trauma presented with portal thrombosis followed by progressive splenomegaly and jaundice. Ultrasonography and percutaneous cholangiography revealed biliary dilatation secondary to choledochal stenosis caused by dilated peribiliary veins, characterizing a case of portal biliopathy. The present case report is aimed at presenting an uncommon cause of this condition.

Immunoglobulin G4-related disease: autoimmune pancreatitis and extrapancreatic manifestations

Abstract We present a case of immunoglobulin G4 (IgG4)-related disease with pancreatic and extrapancreatic involvement, including the biliary and renal systems. Given the importance of imaging methods for the diagnosis of IgG4-related disease and its differentiation from pancreatic adenocarcinoma, we emphasize important abdominal computed tomography and magnetic resonance imaging findings related to this recently recognized systemic autoimmune disease.

Conduta terapêutica atual no adenocarcinoma da cárdia e da junção esofagogástrica

Adenocarcinomas of the cardia and gastroesophageal junction are peculiar entities with three different origins, which differ somewhat from other adenocarcinomas of the stomach in their clinical presentation and pathogenesis, and have a poorer prognosis. In this article the authors reviewed definitions, incidence and epidemiology, etiologic factors, genetic implications, clinical presentation, diagnosis, staging and treatment, with emphasis on the surgical approach, discussing the current management of these cancers. The prognostic factors related specifically to the cardia cancers are: esophageal invasion greater than 3cm, microscopic residual tumor and wall penetration (>T2). Preoperative workup should include computed tomography, and endoscopic ultrasonography and laparoscopy when available. Preoperative recognition of T3/ T4/N2 lesions should indicate inclusion in neo-adjuvant protocols whenever possible. The authors present the results of 46 resected cases of adenocarcinomas of the cardia and GE junction of the Instituto Nacional do Câncer- Brazil (1981-1995). Cure was intended in 29 and palliation in 17 patients. The most common type of resection was total gastrectomy with abdominal esophagectomy (28 cases). Morbidity (major and minor) occurred in 50% of the patients. The main causes were of respiratory origin and fistulas (19.6% each). Death occurred in 44% of the patients with fistula. Postoperative death until the 30th day occurred in 17.24% of the curative cases and in 23.52% of the palliative ones. The median survival time was 68.5 months for stage I, 25 months for stage II, 31 months for stage III and 12.5 months for stage IV diseases. The median survival time was 8 months for palliation and 28.5 months for cure. No long-term survival was obtained with the palliative group, whereas 25% survived five years of more in the curative group. The authors conclude that the surgical approach should be the one the surgeon feels more comfortable with. Complete removal of the disease proved by frozen section, splenectomy and D2 lymphadenectomy should be the standard therapy with curative intent.

Adenoma viloso da ampola de Vater

The aim of this paper is to present a case of a 37-year-old female patient with a benign tumor of the Ampulla of Vater and a brief review of the literature. The patient presented with progressive obstructive jaundice and weigth loss due to the presence of two adenomas of the second portion of duodenum. Laboratory tests confirmed the presence of obstruction of the biliary tree. Ultrasound and CT scan of the abdomen revealed bile duct dilatation. ERCP showed a tumor at the site of the Ampulla of Vater. The biopsies revealed tubular adenoma. She was submitted to local resection of the tumors and sphincteroplasty, since the frozen biopsy at the time of surgery showed no malignancy. During the post-operative follow-up she presented recurrence of symptoms. An upper GI endoscopy revealed a tumor at the Ampulla of Vater. She was then submitted to Whipple procedure with an uneventful recovery.

Apendicite em hérnia femoral com formação de fístula estercoral

The presentation of acute appendicitis in femoral hernia is rare. The gastrointestinal symptons are overshadowed by the local findings. This may lead to delayed diagnosis and complications such as formation of fistula. The authors report a case of a 76-year-old female patient which presented with stercoral fistula after drainage of a right groin abscess ten months earlier.

Hemosuccus pancreaticus: causa rara de hemorragia digestiva maciça

Hemosuccus pancreaticus is a unusual syndrome manifested by hemorrhage into the pancreatic duct and by blood loss through the ampulla of Vater: It may be caused by tumors, arteriovenous malformation, pancreatic lithiasis, aneurism rupture from adjacent vessels, or erosion of pancreatic and peripancreatic vessels due to chronic pancreatitis. The authors describe a case of massive and recurrent gastrointestinal upper hemorrhage in a 26-year-old man without known risk factors for pancreatitis. This man underwent urgent surgery due to gastrointestinal bleeding during the ínvestigation. During the procedure, blood was found in the intestinal lumen and a tumor in the head of pancreas with two centimeters of diameter: A gastroduodenopancreatectomy was performed. Histological study showed chronic pancreatitis with a fistula from the pancreatic vessels to the Wirsung duct. The patient was discharged without postoperative complications and after months, remains assymptomatic.

Fístula pieloduodenal espontânea

Authors present two cases of spontaneous pyeloduodenal fistulas associated to suppurative kidney disease. In both cases the fistulas developed from pyonephrosis and perirenal abscesso Diagnosis was made through intravenous or retrograde pyelogram and two patients were successfully treated by nephrectomy and primary duodenorraphy. Authors present a literature review concluding that 72 additional cases of pyeloduodenal fistulas have been described.

Cisto de colédoco em adulto

Choledochal cyst is a rare congenital malformation of the biliary tree, and aproximately 25% of them are diagnosed in adults. Appropriate surgical management of these lesions depends on the anatomic site and extension of the cystic process. The recognized association of the bile duct cysts with hepatobiliary malignant disease has important surgical implications. Total cyst removal and cholecistectomy with Roux-en- Y hepaticojejunostomy was performed in a 47 year old female with a common bile duct cyst tipe 1 postoperative period was uneventful. A review of literature is presented.

Fístula colecistogástrica

The authors report two cases of cholecistogastric fistula, both in female patients. These patients presented abdominal pain and dispeptic hipostenic syndrome, being diagnosed as calculous cholecistopathy. ln one patient, gastroduodenoscopy showed a fistula orifice in the stomach. ln the other case, the diagnosis was only made during the operation. The surgical procedure was cholecistectomy and gastric suture, with satisfatory postoperative evolution.

Tuberculose entérica

The authors reports two patients with operated from enteric tuberculosis. Tuberculosis involving the intestinal tract may be due to either Mycobacterium tuberculosis or M. bovis. In the former situation, the disease is primary to the lungs and is carried to the intestinal tract by swallowing sputum. The latter organism produces infection associated with swallowed nonpasteurized milk. This condition is extremely unusual in most western countries, since pasteurization of milk is standardized. The diagnosis was performed through laparotomy because of symptoms suggestive of intestine obstruction. Inflammatory reactions were observed on the small intestine (jejunum-ileum) in both cases. The presence of tuberculosis of the lungs was observed in one patient. The chemotherapic treatment was estabilished after the histopathologic diagnosis. The distinction between tuberculosis and Crohn's disease may not be possible by radiography or endoscopy. Videolaparoscopy has been found to be an useful procedure for the early diagnosis of Enteric Tuberculosis. In spite of the epidemiology knowledge, clinical control and improvement in treatment, extra pulmonary tuberculosis rate from concealed focus has been increased, due to AIDS poverty in certain populational groups and immigration from Asia to wertern countries. Compared with immunocompetent patients, the proportion of extrapulmonary tuberculosis is much higher in patients with AIDS, justfying the increased frequency of reports of intestinal tuberculosis in these patients.

Perfuração espontânea de colédoco em adolescente

Spontaneous perforation of the common bile duct is rare. It happens predominantly in children and it is related to obstructive disease of the biliary tract. We present a case of an 18 year-old male patient, with ulcerative rectocolitis associated with malignant tumor of the head of pancreas. The patient developed an acute abdomen syndrome and laparotomy, a spontaneous perforation of common bile duct was evidenced. The authors make a revision of the clinical aspects of that pathology.

Adenomioma da papila de vater em adulto jovem

The authors report a case of adenomyoma of papilla of Vater in a young adult, a rare pathology in this age and site. The commonest clinical findings are abdominal pain, dyspepsia and jaundice, as in this case in which the patient referred these symptoms for several months. The diagnosis is usually difficult before surgery, because the radiological and endoscopic appearances are difficult to interpret, since they may only show obstruction and enlargement of the biliary tract; in this way, the endoscopic biopsy may be useful. In the present case the computed tomography, abdominal scan and intraoperative cholangiography only demonstrated obstruction and enlargement of the biliary tract, without the presence of gallstones. The treatment is usually lesion resection according to its size, performing the total resection in those cases of extensive involvement of the digestive tract, as it was performed in this case, due to the dimension of the lesion and its malignant appearance. The patient was discharged from hospital on the thirteenth postoperative day, with a histological diagnosis of adenomyoma of papilla of Vater. Three months after the procedure the patient was asymptomatic.
