Postoperative maintenance therapy for inflammatory bowel disease.
2006
. Curr Opin Gastroenterol. 2006 Jul;22(4):377-81. Postoperative maintenance therapy for inflammatory bowel disease. Cottone M, Orlando A, Modesto I. Department of General Medicine, Pneumology and Nutrition Clinic, Palermo University, Palermo, Italy. PURPOSE OF REVIEW: This review will highlight the knowledge gained from studies published in the year 2005 on maintenance treatment after surgery for inflammatory bowel diseases. RECENT FINDINGS: In Crohn's disease the role of smoking in increasing the risk of relapse and recurrence after surgery is confirmed. Ornidazole seems effective in reducing endoscopic recurrence and clinical relapse after surgery. Probiotics do not appear to be effective…
Role of the gastroenterologist in the management of the obese patient.
2017
Obesity is a highly prevalent disease worldwide, and one in which gastroenterologists can play an important role. Some digestive diseases are more common in obese patients, and preoperative evaluation may be required in some cases. Additionally, bariatric surgery can lead to digestive complications in the short and long term that require intervention, and endoscopic treatment can be an important factor in weight loss. The aim of this review is to highlight the role of the gastroenterologist in the management of obese patients who are either scheduled for or have undergone surgical or endoscopic treatment for obesity.
Interventionelle ERCP bei Patienten mit Cholestase: Häufigkeit und Antibiotikaresistenz der biliären Keimbesiedlung
2001
Interventional ERCP in patients with cholestasis. Degree of biliary bacterial colonization and antibiotic resistance. Biliary obstruction together with bacterial colonization of the bile duct may lead to development of acute cholangitis. The aim of our prospective study was to investigate the presence and degree of biliary bacterial colonization by means of bile aspiration during ERCP in patients with biliary obstruction. Furthermore, we evaluated antibiotic therapy regimens, which would cover the bacterial species obtained by ERCP and subsequent culture in each patient. In addition, analysis of risk factors was performed that would predispose to the development of cholangitis.80 patients w…
Improving opportunities for effective management of gastro-oesophageal reflux disease
2002
The recent introduction of proton pump inhibitors has extraordinarily improved the therapeutic approach to gastro-oesophageal reflux disease. The concept of decreasing gastric acid secretion and increasing the pH in the lower oesophagus has been demonstrated to be therapeutically effective and the higher the level of pH achieved, the better the results. In spite of the evident efficacy of these molecules, there are still many patients who will continue to have symptoms despite medical treatment. Proton pump inhibitors suppress gastric acidity, but this effect shows a remarkable interindividual variation depending on different reasons. Thus, it is still possible to optimise medical therapy f…
Carboxyl nonsteroidal anti-inflammatory drugs are efficiently glucuronidated by microsomes of the human gastrointestinal tract.
2004
Limited studies have been carried out on the biotransformation of carboxyl nonsteroidal anti-inflammatory drugs (NSAIDs) in the liver. However, the role of the intestine in NSAID metabolism has not been investigated. In this report, the contribution of UDP-glucuronosyltransferases (UGTs) in the human gastrointestinal (GI) tract from five donors to the glucuronidation of the NSAIDs, RS-ketoprofen, S-naproxen, RS- and S-etodolac, was investigated. UGT activity and, for some donors, mRNA levels were evaluated. All NSAIDs were glucuronidated throughout the GI tract; however, glucuronidation was low in stomach and duodenum as compared to the remainder of the intestine. RT-PCR analysis demonstrat…
Electrospun bioactive mats enriched with Ca-polyphosphate/retinol nanospheres as potential wound dressing
2015
Background While electrospun materials have been frequently used in tissue engineering no wound dressings exist that significantly improved wound healing effectively. Methods We succeeded to fabricate three-dimensional (3D) electrospun poly(D,l-lactide) (PLA) fiber mats into which nanospheres, formed from amorphous calcium polyphosphate (polyP) nanoparticles (NP) and encapsulated retinol (“retinol/aCa-polyP-NS” nanospheres [NS]), had been incorporated. Results Experiments with MC3T3-E1 cells revealed that co-incubation of the cells with Ca-polyP together with retinol (or incubation with retinol/aCa-polyP-NS) resulted in a significant synergistic effect on cell growth compared with particle-…
Amphiregulin activates human hepatic stellate cells and is upregulated in non alcoholic steatohepatitis
2015
AbstractAmphiregulin (AR) involvement in liver fibrogenesis and hepatic stellate cells (HSC) regulation is under study. Non-alcoholic fatty liver disease (NAFLD) and its more severe form non-alcoholic steatohepatitis (NASH) may progress to cirrhosis and hepatocellular cancer (HCC). Our aim was to investigate ex vivo the effect of AR on human primary HSC (hHSC) and verify in vivo the relevance of AR in NAFLD fibrogenesis. hHSC isolated from healthy liver segments were analyzed for expression of AR and its activator, TNF-α converting enzyme (TACE). AR induction of hHSC proliferation and matrix production was estimated in the presence of antagonists. AR involvement in fibrogenesis was also ass…
Eating disorders on the web: risks and resources.
2009
Our work is aimed at exploring the recent literature data on web sites, forums, and blogs, which promote eating disorders as normal life styles and their implication in the changes of the psychopatology of such disorders. We also want to understand whether new technologies have an impact in the course of the disorders or, on the other hand, whether they can also represent an instrument for searching help or information about them. The search strategy included a search of PsycINFO, Medline, and Ovid databases to identify research reports about pro-ana sites and their implication on the course of anorexia using the following key words: pro-ana, thinspiration, anorexia-web, online help eating …
What could have caused this weight loss?

International audience; Achalasia is rare and often diagnosed late.It is characterized by functional gastro-oesophageal sphincter obstruction.Aspiration pneumonia may complicate the achalasia.Intrasphincteric botulinum toxin injection is one of the main treatments for achalasia.
Cetuximab-induced skin exanthema: prophylactic and reactive skin therapy are equally effective
2013
Purpose Treatment with cetuximab is accompanied by the development of an acneiform follicular skin exanthema in more than 80 % of patients. Severe exanthema (grade III/IV) develops in about 9–19 % of patients with the necessity of cetuximab dose reduction or cessation.
