Behcet`s disease associated with celiac disease: a very rare association

There are common findings between Beh double dagger et`s disease (BD) and celiac disease (CD); however, association in the same patient is a rarity. We relate the third case in the literature of this overlap in a 40-year-old woman with history of obstipation since her childhood. She also presented asymmetric polyarthralgia, loss of weight, anemia, oral recurrent aphthas (> 3/year) and genital ulcerations, inflammatory lower back pain, bowel bleeding and abdominal colic. Afterwards, she presented episodes of erythema nodosum, superficial thrombophlebitis, pseudofolliculitis and aseptic meningitis, thus fulfilling criteria for BD. Due to persistence of the digestive complaints, a gastrointestinal endoscopy was performed. The biopsy showed chronic duodenitis with intraepithelial lymphocytosis, crypt hyperplasia, and villous atrophy. Endomysial antibody was positive. She fulfilled the diagnosis criteria for CD; a gluten-free diet was applied with clinical improvement. Ascertaining whether pathogenic mechanisms are common in these two conditions requires further investigation.

Constipation in intensive care unit: Incidence and risk factors

Purpose: Although gastrointestinal motility disorders are common in critically ill patients, constipation and its implications have received very little attention. We aimed to determine the incidence of constipation to find risk factors and its implications in critically ill patients Materials and Methods: During a 6-month period, we enrolled all patients admitted to an intensive care unit from an universitary hospital who stayed 3 or more days. Patients submitted to bowel surgery were excluded. Results: Constipation occurred in 69.9% of the patients. There was no difference between constipated and not constipated in terms of sex, age, Acute Physiology and Chronic Health Evaluation II, type of admission (surgical, clinical, or trauma), opiate use, antibiotic therapy, and mechanical ventilation. Early (<24 hours) enteral nutrition was associated with less constipation, a finding that persisted at multivariable analysis (P < .01). Constipation was not associated with greater intensive care unit or mortality, length of stay, or days free from mechanical ventilation. Conclusions: Constipation is very common among critically ill patients. Early enteral nutrition is associated with earlier return of bowel function. (C) 2009 Elsevier Inc. All rights reserved.

Synchronous adenocarcinoma of the major and minor duodenal papilla

A 50-year-old woman presented with pancreatitis, fluctuant jaundice, weight loss, and abdominal pain. Contrast-enhanced computed tomography and abdominal ultrasound showed slight dilatation of the biliary tree and gallbladder without calculi. Endoscopy demonstrated a tumor protruding from the papilla of Vater. First endoscopically biopsy diagnosed no tumor, and a second biopsy diagnosed as papillary adenocarcinoma. The patient underwent duodenopancreatectomy. The specimen was fixed in formalin (10%). The tissue was processed routinely, and paraffin sections were stained with hematoxylin-eosin and periodic acid Schiff. Gross examination showed two tumors seen as prolapsed nodules growing isolated from the minor and major duodenal papillae measuring 1.5 and 1.0 cm, respectively, both covered by duodenal mucosa and the histologic study of both lesions demonstrated a moderately differentiated tubular adenocarcinoma, which invaded duodenal wall. After surgery, she is alive 24 months without evidence of recurrence.

Management of Neuroendocrine Tumors: A Meeting of Experts from Latin America

A panel of experts from Latin America convened in Brazil, in May of 2007, for consensus recommendations regarding the management of neuroendocrine tumors ( NETs) of the gastrointestinal tract and pancreas. The recently introduced World Health Organization classification of NETs represents a step forward, but the former classification of carcinoids into foregut, midgut and hindgut is still likely to be useful in the near future. Macroscopic description of the tumor should be followed by light microscopic examination and immunohistochemical staining, whereas other techniques might not be widely available in Latin America. Surgery remains the mainstay of treatment for patients with potentially curable tumors, and adequate selection is paramount in order to optimize treatment results. Regarding systemic therapy, patients with well-differentiated tumors or islet-cell carcinomas may be categorized as having indolent disease, while patients with poorly differentiated, anaplastic, and small-cell carcinomas, or with atypical carcinoids, may be approached initially as having aggressive disease. Somatostatin analogues play a cytostatic role in indolent tumors, and chemotherapy may play a role against other, more aggressive NETs. Obviously, there is an urgent need for novel therapies that are effective against NETs. Copyright (C) 2008 S. Karger AG, Basel

Uveitis in celiac disease with an excellent response to gluten-free diet: third case described

To describe the case of a patient with celiac disease who achieved a complete response to a gluten-free diet. A 28-year-old woman presented with diarrhea, oral ulcers, and refractory uveitis of 2.5-years duration. She was treated with prednisone, mydriatic drops, and infliximab with no response. She was referred to our hospital at which point her previous diagnosis of uveitis was confirmed; she was also diagnosed with right-sided sacro-iliitis. The patient did not have arthritis or any skin conditions. Three tests for fecal parasites and a fecal leukocyte were negative. Endoscopy revealed atrophic appearance of the duodenal mucosa. Biopsy showed atrophy of the duodenal villi with intra-epithelial lymphocytes, hyperplasia of the crypts, and chronic inflammatory infiltrate. The search for antiendomysial antibody was > 1/1,280. The patient was started on a gluten-free diet and after 3 months demonstrated significant improvement of gastrointestinal symptoms and uveitis, as well as a reduction of antiendomysial antibodies (1/80). After 6 months, there was complete remission of gastrointestinal symptoms and total control of uveitis. The antiendomysial antibody was negative at that time. Clinical uveitis as a manifestation of celiac disease has been described in only two cases in the literature. This case study is the third to demonstrate that uveitis is a clinical symptom that can be addressed in patients with celiac disease.

Impact on Dyslipidemia of the Laparoscopic Ileal Interposition Associated to Sleeve Gastrectomy in Type 2 Diabetic Patients

Dyslipidemia is known to increase significantly the odds of major cardiovascular events in the general population. Its control becomes even more important in the type 2 diabetic (T2DM) population. Bariatric surgeries, especially gastric bypass, are effective in achieving long-term control of dyslipidemia in morbidly obese patients. The objective of the study was to evaluate the control of dyslipidemia in patients with T2DM and BMI below 30 that were submitted to the laparoscopic ileal interposition associated to sleeve gastrectomy. An observational transversal study was performed in a tertiary care hospital, between June 2005 and August 2007. Mean follow-up was 24.5 months (range 12-38). The procedure was performed in 72 patients: 51 were men and 21 were women. Mean age was 53.1 years (38-66). Mean BMI was 27 kg/m(2) (22.1-29.4). Mean duration of T2DM was 10.5 years (3-22). Mean HbA1c was 8.5%. Hypercholesterolemia was diagnosed in 68% of the patients and hypertriglyceridemia in 63.9%. Mean postoperative BMI was 21.2.kg/m(2) (17-26.7). Mean postoperative HbA1c was 6.1%, ranging 4.4% to 8.3%. Overall, 86.1% of the patients achieved an adequate glycemic control (HbA1c < 7) without anti-diabetic medication. HbA1c below 6 was achieved by 50%, 36.1% had HbA1c between 6 and 7, and 13.9% had HbA1c above 7. Total hypercholesterolemia was normalized in 91.8% and hypertriglyceridemia in 89.1% of patients. Low-density lipoprotein below 100 mg/dl was seen in 85.7%. The laparoscopic ileal interposition associated to sleeve gastrectomy was an effective operation for the regression of dyslipidemia and T2DM in a non-obese population.

Extrahepatic portal vein thrombosis after umbilical catheterization: is it a good choice for Rex shunt?

Background: Extrahepatic portal vein thrombosis (EHPVT) is an important cause of portal hypertension in children. Rex shunt has been used successfully to treat these patients. Methods: We report our experience in 19 infants and children (5 months to 14 years) with HPVT eligible for a mesenteric-portal surgical shunt with left internal jugular vein autograft. Eight children had idiopathic EHPVT, nine had post-umbilical catheterization EHPVT, one had portal vein agenesis, and one had posttransplant EHPVT. Results: It was possible to perform the Rex shunt in all patients except for 8 of 9 cases in the post-umbilical catheterization EHPVT group. A Warren procedure was performed in 4 of those patients and a proximal splenorenal shunt in 1. Current follow-up ranges from 3 to 26 months. Shunt thrombosis occurred in one patient with portal vein agenesis and associated cardiac anomaly. Portal hypertension has significantly improved after surgery. None of our patients have experienced new bleeding episodes until now. Conclusions: The Rex shunt should be considered in the treatment of children with idiopathic EHPVT experiencing repeated gastrointestinal bleeding episodes refractory to endoscopic treatment. Nevertheless, the role of this operation for children with post-umbilical catheterization EHPVT is yet to be clearly evaluated. (C) 2011 Elsevier Inc. All rights reserved.

Should patients with esophageal atresia be submitted to esophageal substitution before they start walking?

P>Esophagocoloplasty and gastric transposition are two major methods for esophageal substitution in children with esophageal atresia, and there is broad agreement that these operations should not be performed before the children start walking. However, there are some reported advantages of performing such operations in the first months of life or in the neonatal period. In this study, we compared our experience with esophageal substitution procedures performed in walking children with esophageal atresia, with the outcomes of children who had the operation before the third month of life reported in the literature. The purpose of this study was to establish if we have to wait until the children start walking before indicating the esophageal replacement procedure. From February 1978 to October 2009, 129 children with esophageal atresia underwent esophageal replacement in our hospital (99 colonic interpositions and 30 gastric transpositions). The records of these patients were reviewed for data regarding demographics, complications (leaks, graft failures, strictures, and graft torsion), and mortality and compared with those reported in the two main articles on esophageal replacement in the neonatal period or in patients less than 3 months of age. The main complication of our casuistic was cervical anastomosis leakage, which sealed spontaneously in all except in four patients. One patient of the esophagocoloplasty group developed graft necrosis and three patients in the gastric transposition group had gastric outlet obstruction, secondary to axial torsion of the stomach placed in the retrosternal space. The long-term outcome of the patients in both groups was considered good to excellent in terms of normal weight gain, absence of dysphagia, and other gastrointestinal symptoms. The comparisons of the main complications and mortality rates in walking children with esophageal substitutions performed in the first months of life showed that the incidences of cervical anastomotic leaks and graft failures were similar, but mortality rate in the first few months of life was significantly greater than that observed in our group of patients (P = 0.001). Based on the comparison of our results with those of published series, we conclude that the recommendation of performing esophagocoloplasty or total gastric transposition in children with esophageal atresia after they start walking is still valid.

Congenital intrahepatic arterioportal fistula presenting as severe undernutrition and chronic watery diarrhea in a 2-year-old girl

Intrahepatic arterioportal fistula (IAPF) is a rare cause of portal hypertension in young children. We report the case of a 2-year-old girl with severe undernutrition, chronic watery diarrhea, and gastrointestinal bleeding because of a congenital intrahepatic arterioportal fistula. Radiographic embolization and surgical ligation of the left hepatic artery were attempted, with no resolution of the symptoms. So, a left lobectomy was performed, with excellent results and prompt disappearance of the diarrhea. Hepatectomy should be considered as a definitive and reliable. therapy for congenital IAPF.

Conversion to Sirolimus in Kidney-Pancreas and Pancreas Transplantation

Reports on the use of sirolimus (SRL) in pancreas transplantation are still limited. The aim of this study was to evaluate the outcome of SRL conversion in pancreas transplant patients. Among 247 patients undergoing simultaneous kidney-pancreas or solitary pancreas transplantation, 33 (13%) were converted to SRL. The reasons for conversion were calcineurin inhibitors (CNI) nephrotoxicity (n = 24; 73%), severe neurotoxicity owing to CNI (n = 1; 3%), severe and/or recurrent acute rejection episodes (n = 7; 21.%), gastrointestinal (GI) side effects of mycophenolate mofetil (MMF; n = 5; 15%), and hyperglycemia (n = 4; 12%). Before conversion, all patients were maintained on a CNI, MMF, and low-dose steroids. They were gradually converted to SRL associated with either CNI or MMF withdrawal. Sixty-three percent (n = 15) of patients who were converted owing to CNI nephrotoxicity, showed stable or improved renal function. At 12 months after conversion, serum creatinine levels were significantly decreased in this group (2.2 +/- 0.5 vs 1.6 +/- 0.3 mg/dL; P = .001) and C-peptide values increased (2.9 +/- 1.1.1 vs 3.1 +/- 1.3 nmol/L; P = .01.8). The only patient with leucoencephalopathy showed improved neurologic status after SRL conversion. All patients converted to SRL because of GI side effects of MMF showed improvements, and none of those converted because of hyperglycemia experienced improvement. There were no episodes of acute rejection after conversion. We concluded that conversion to SRL in pancreas transplantation should be considered an important alternative strategy, particularly for CNI nephrotoxicity and neurotoxicity, and in cases of severe diarrhea due to MMF.

Late response to anti-TNF-alpha therapy in refractory mucocutaneous lesions of Beh double dagger et`s disease

Beh double dagger et`s disease (BD) is a multisystem chronic inflammatory disorder characterized by oral and genital ulceration and ocular involvement. Recurrent oral and genital ulcers are the most common symptoms of BD and occur in more than 80% of patients. The treatments of these disease manifestations include colchicine, corticosteroids and immunosuppressive drugs in severe cases. Anti-TNF-alpha therapy may be useful in refractory severe BD, particularly for ocular, central nervous system, gastrointestinal and refractory mucocutaneous lesions. During a 2-year period, 280 patients suffering from rheumatic diseases received anti-TNF-alpha agents at the infusion center of our University Hospital. Two patients (0.7%) presented BD; one of them had celiac disease as well, with recalcitrant mucocutaneous lesions that were not responsive to immunosuppressive drugs. We reported those patients who were successfully treated with infliximab and adalimumab, despite their late response.

Clinical Approaches to Preserve beta-Cell Function in Diabetes

In type 2 diabetes (DM2) there is progressive deterioration in beta-cell function and mass. It was found that islet function was about 50% of normal at the time of diagnosis and reduction in beta-cell mass of about 60% at necropsy (accelerated apoptosis). Among the interventions to preserve the beta-cells, those to lead to short-term improvement of beta-cell secretion are weight loss, metformin, sulfonylureas, and insulin. The long-term improvement was demonstrated with short-term intensive insulin therapy of newly diagnosed DM2, the use of antiapoptotic drugs such as glitazones, and the use of glucagon-like peptide-1 receptor agonists (GLP-1 mimetics), not inactivated by the enzyme dipeptidyl peptidase 4 and/or to inhibit that enzyme (GLP-1 enhancers). The incretin hormones are released from the gastrointestinal tract in response to nutrient ingestion to enhance glucose-dependent insulin secretion from the pancreas and overall maintenance of glucose homeostasis. From the two major incretins, GLP-1 and GIP (glucose-dependent insulinotropic polypeptide), only the first one or its mimetics or enhancers can be used for treatment. The GLP-1 mimetics exenatide and liraglutide as well as the DPP4 inhibitors (sitagliptin and vildagliptin) were approved for treatment of DM2.

Helminthic Diseases in the Abdomen: An Epidemiologic and Radiologic Overview

Helminthic diseases have a worldwide distribution. They affect billions of people in endemic areas and can result in serious clinical complications. Some parasites have a human gastrointestinal life cycle with resultant abdominal manifestations. However, the symptoms of helminthic diseases are usually nonspecific. Radiologic imaging, along with the identification of risk factors, may help narrow the differential diagnosis. To avoid diagnostic delays, radiologists should be familiar with the geographic distribution, transmission cycle, and characteristic and atypical manifestations of common helminthic diseases at abdominal imaging with radiography, computed tomography, magnetic resonance imaging, and ultrasonography. Awareness of the clinical, epidemiologic, and pathogenic characteristics of these diseases also may be helpful for narrowing the diagnosis when imaging features are nonspecific.

Endoscopic treatment of Zenker`s diyerticulum by harmonic scalpel

Background: Zenker`s diverticulum (ZD) is a rare condition with a reported prevalence of 0.01% to 0.11% in the general population. Endoscopic treatment consists of the division of the septum between the diverticulum and the esophagus, within which the cricopharyngeal muscle is contained. Diathermic monopolar current, argon plasma coagulation, and laser have been used to incise the muscular septum with satisfactory results. The main limitation of endoscopic treatment is the occurrence of complications. Perforation and hemorrhage are reported in as many as 23% and 10% of patients, respectively. Objective: The aim of this study was to use the technique of endoscopic diverticulotomy by using a harmonic scalpel in patients with ZD and to demonstrate the feasibility of using flexible and rigid devices in ZD treatment. Design: Case series study. Standard protocol was used for patient management, endoscopic procedure, and data collection. Setting: Single endoscopist demonstrating preliminary results. Patients: Five patients (4 men; median standard deviation [SD] age 69.6 +/- 9.06 years, range 59-83 years) with ZD were treated with this technique. All patients reported dysphagia and halitosis. The diagnosis was based on clinical, endoscopic, and radiographic findings. Interventions: All patients received general anesthesia and were placed in the left lateral position. A standard videogastroscope (9.8 mm) and a stiff guidewire were used to insert and achieve an adequate exposure of the ZD septum. The septum was divided using a harmonic scalpel under thin endoscope (5.2 mm) visualization through a soft diverticuloscope. Main Outcome Measurement: Feasibility of an endoscopic technique by using rigid and flexible devices to treat ZD. Results: Four patients (80%) were successfully treated in 1 session. The median SD size of the diverticulum was 3.6 +/- 0.89 cm (range 3-5 cm). Median SD procedure time was 17.33 +/- 2.33 minutes (range 15-20 minutes) in 6 procedures. No hemorrhage or perforation occurred. One patient (20%) required a second session to complete dissection of the ZD septum. All patients demonstrated improvement of dysphagia score after treatment. Limitations: Small case series design. Conclusions: Endoscopic treatment of ZD by harmonic scalpel through a soft diverticuloscope was feasible and effective in this small case series. Larger studies are warranted to further evaluate this technique.

Evaluating Causes of Death in Familial Adenomatous Polyposis

Background Familial adenomatous polyposis is a genetic syndrome associated with an increased risk of colorectal cancer (CRC) and different extracolonic manifestations Goals The goal of this study is to evaluate the frequency of death causes Material and Methods Charts from 97 patients treated from 1977 to 2008 were reviewed Retrieved data and family information allowed us to classify causes of death in those related to CCR to other malignancies or other causes Results There were analyzed data from 46 men (47 4%) and 51 women (52 6%) with an average age of 35 1 years (14 to 82) At diagnosis, 57 patients (58 7%) already had CRC-associated polyposis There were performed 93 colectomies, one internal diversion, and one partial resection Two patients were not operated on Results from 19 deceased patients (19 5%) were analyzed CRC, other tumors (desmoid tumors, lymphoma, and gastric cancer), and other causes (complication of duodenal cancer surgery, complication after ileorectal anastomosis (IRA), and coronary disease) were responsible for 12 (63 1%), four (21 1%), and three (15 8%) of all deaths, respectively Death from CRC occurred in the context of either systemic, rectal, or pouch recurrence Desmoid disease was the second cause of death (10 5% of all causes), leading to a fatal outcome 22% of all patients who developed DT during the study period Upper digestive carcinomas were responsible for other two death cases Conclusions (1) CRC is still the most prevalent cause of death, (2) even after curative resections, CRC can cause death through rectal or pouch malignization, (3) long-term survival was also strongly related to the development of extracolonic neoplasia, especially desmoid tumors and gastroduodenal carcinoma, (4) our results raise the need for local improvement in familiar screening and help us to define follow-up strategies and patient-information standards
