For almost one hundred years abdominoperineal excision has been the standard treatment of choice for rectal cancer. With advances in the techniques for rectal resection and anastomosis, anterior resection with preservation of the sphincter function has become the preferred treatment for rectal cancers, except for those cancers very close to the anal sphincter. The main reason for this has been the conviction that the quality of life for patients with a colostomy after abdominoperineal excision was poorer than for patients undergoing an operation with a sphincter-preserving technique. However, patients having sphincter-preserving operations may experience symptoms affecting their quality of life that are different from stoma-patients. To compare the quality of life in rectal cancer patients with or without permanent colostomy. We searched PUBMED, EMBASE, LILACS, the Cochrane Central Register of Controlled Trials (CENTRAL), the Cochrane Colorectal Cancer Group's specialised register. Abstract books from major gastroenterological and colorectal congresses were searched. Reference lists of the selected articles were scrutinized. All controlled clinical trials and observational studies in which quality of life was measured in patients with rectal cancer having either abdominoperineal excision/Hartmann's operation or low anterior resection, using a validated quality of life instrument, were considered. One reviewer (JP) checked the titles and abstracts identified from the databases and hand search. Full text copies of all studies of possible relevance were obtained. The reviewer decided which studies met the inclusion criteria. Both reviewers independently extracted data. If information was insufficient the original author was contacted to obtain missing data. Extracted data were cross-checked and discrepancies resolved by consensus. Sixty-nine potential studies were identified. Thirty-five of these, all non-randomised and representing 5127 participants met the inclusion criteria. Fourteen trials found that people undergoing abdominoperineal excision/Hartmann's operation did not have poorer quality of life measures than patients undergoing anterior resection. The rest of the studies found some difference, but not always in favour of non-stoma patients. Due to clinical heterogeneity and the fact that all studies were observational trials, meta-analysis of the included studies was not possible. The studies included in this review do not allow firm conclusions as to the question of whether the quality of life of people after anterior resection is superior to that of people after abdominoperineal excision/Hartmann's operation. The included studies challenges the assumption that anterior resection patients fare better. Larger, better designed and executed prospective studies are needed to answer this question. Source

A combination of pegylated interferon and ribavarin is currently the gold standard for the treatment of chronic hepatitis C infection. Interferon therapy can lead to the development of an autoimmune phenomenon that can be sub-clinical or clinical, and the presence of autoantibodies increases the risk. Thyroiditis is the most common autoimmune manifestation of interferon therapy and can present during treatment or after the completion of treatment. On the other hand, psoriasis is rare, and has been reported to occur within weeks of starting the treatment. We report a case of a 46-year-old indigen woman who was positive for multiple autoantibodies, and developed autoimmune thyroiditis that manifested as hypothyroidism during pegylated interferon and ribavarin therapy for chronic hepatitis C infection. She also developed plaque psoriasis after the completion of therapy. In our case, the association with thyroiditis was definite, whereas that with psoriasis was less definite. However, it is still important for clinicians to be aware of such rare associations. Source

Branched chain amino acids (BCAAs) have been shown to affect gene expression, protein metabolism, apoptosis and regeneration of hepatocytes, and insulin resistance. They have also been shown to inhibit the proliferation of liver cancer cells in vitro, and are essential for lymphocyte proliferation and dendritic cell maturation. In patients with advanced chronic liver disease, BCAA concentrations are low, whereas the concentrations of aromatic amino acids such as phenylalanine and tyrosine are high, conditions that may be closely associated with hepatic encephalopathy and the prognosis of these patients. Based on these basic observations, patients with advanced chronic liver disease have been treated clinically with BCAA-rich medicines, with positive effects. © 2013 Baishideng Publishing Group Co., Limited.

Background Helicobacter pylori infection is the main cause of gastric mucosa-associated lymphoid tissue (MALT) lymphoma. Aim To review several common misconceptions in the management of H. pylori-associated gastric MALT-lymphoma. Methods Bibliographical searches were performed in MEDLINE up to June 2011. Results If adequate diagnostic methods are used, and if only low-grade lymphomas are considered, the prevalence of H. pylori infection is very high (almost 90%). H. pylori eradication is effective in treating approximately 80% of patients with early stage lymphoma. In H. pylori-positive gastric high-grade lymphomas, antibiotic therapy should always be prescribed, as approximately 50% of them regress after H. pylori eradication. Patients with early stage MALT lymphoma negative for H. pylori might still benefit from antibiotic treatment as the sole treatment. Complete remission of gastric MALT lymphoma after H. pylori eradication can take even >12 months. PCR assay for the detection of monoclonal B cells remains positive in many cases after complete remission has been reached. Patients with a persistent clonal band should not be treated unless the lymphoma can be histologically demonstrated. Synchronous occurrence of gastric adenocarcinoma and MALT lymphoma has been repeatedly reported. In some patients in complete remission, eradication of H. pylori does not prevent later development of early gastric cancer. Gastric lymphoma recurrence occurs in some patients after both bacterial and lymphoma regression. H. pylori reinfection does not constitute a prerequisite for lymphoma recurrence. Conclusions The present article states several misconceptions in the management of H. pylori-associated gastric MALT-lymphoma in clinical practice, reviews the related scientific evidence and proposes the adequate attitude in each case. © 2011 Blackwell Publishing Ltd.

The introduction of capsule endoscopy (CE) in clinical practice increased the interest for the study of the small-bowel. Consequently, in about 10 years, an impressive quantity of literature on indications, diagnostic yield (DY), safety profile and technical evolution of CE has been published as well as several reviews. At present time, there are 5 small-bowel capsule enteroscopy (SBCE) models in the worldwide market. Head-to-head trials have showed in the great majority of studies comparable results in terms of D Y, image quality and completion rate. CE meta-analyses formed the basis of national/international guidelines; these guidelines place CE in a prime position for the diagnostic work-up of patients with obscure gastrointestinal bleeding, known and/or suspected Crohn's disease and possible small-bowel neoplasia. A 2-L polyethylene glycol-based purge, administered the day before the procedure, is the most widely practiced preparation regimen. Whether this regimen can be further improved (i.e., by further decreasing its volume, changing the timing of administration, coupling it with prokinetics and/or other factors) or if it can really affect the D Y, is still under discussion. Faecal calprotectin has been used in SBCE studies in two settings: in patients taking non-steroidal anti-inflammatory drugs, to evaluate the type and extent of mucosal damage and, more importantly from a clinical point of view, in patients with known or suspected Crohn's disease for assessment of inflammation activity. Although there is still a lot of debate around the exact reasons of SBCE poor performance in various small-bowel segments, it is worth to remember that the capsule progress is non-steerable, hence more rapid in the proximal than in lower segments of the small-bowel. Capsule aspiration, a relatively unexpected complication, has been reported with increasing frequency. This is probably related with the increase in the mean age of patients undergoing CE. CE video review is a time-consuming procedure. Therefore, several attempts have been made to develop technical software features, in order to make CE video analysis easier and shorter (without jeopardizing its accuracy). Suspected Blood Indicator, QuickView and Fujinon Intelligent Chromo Endoscopy are some of the software tools that have been checked in various clinical studies to date. © 2013 Baishideng.
