Transition of gastroenterological patients from paediatric to adult care: A position statement by the Italian Societies of Gastroenterology.

In 2013, four Italian Gastroenterological Societies (the Italian Society of Paediatric Gastroenterology, Hepatology and Nutrition, the Italian Society of Hospital Gastroenterologists and Endoscopists, the Italian Society of Endoscopy, and the Italian Society of Gastroenterology) formed a joint panel of experts with the aim of preparing an official statement on transition medicine in Gastroenterology. The transition of adolescents from paediatric to adult care is a crucial moment in managing chronic diseases such as celiac disease, inflammatory bowel disease, liver disease and liver transplantation. Improved medical treatment and availability of new drugs and surgical techniques have improved the prognosis of many paediatric disorders, prolonging survival, thus making the transition to adulthood possible and necessary.

Megaduodenum: an unusual presentation of amyloidosis?

Amyloidosis, a potentially fatal disease, is characterized by an abnormal deposition of autologous proteins. Heart, liver, kidneys, lung, thyroid, skin and the gastrointestinal tract can be involved; in this last case mucosal alterations or disturbances of the motility leading to pseudo-obstruction, bleeding, diarrhea and malabsorption can be present. However, the data concerning the possible gastrointestinal presentations of amyloidosis are scanty and heterogeneous.

Infectious serologies and autoantibodies in inflammatory bowel disease: insinuations at a true pathogenic role.

The aim of this study was to reevaluate the role of infection in inflammatory bowel disease (IBD). Sera from 119 patients with IBD [80 with Crohn's disease (CD); 39 with ulcerative colitis] and 98 healthy controls were assessed using the Bio-Rad BioPlex 2200 for the presence of Toxoplasma gondii, cytomegalovirus, Epstein-Barr virus, Treponema pallidum, and Saccharomyces cerevisiae. Hepatitis B virus, hepatitis C virus (HCV), and anti-Helicobacter pylori antibodies were assessed by ELISA.

Diagnostic value of faecal calprotectin in unselected outpatients referred for colonoscopy: A multicenter prospective study.

Objectives: To evaluate the role of faecal calprotectin in consecutive outpatients referred for colonoscopy.

Methods: Outpatients undergoing colonoscopy at five participating institutions were eligible. Demographic and clinical data were collected.

Elevated B cell-activating factor of the tumour necrosis factor family in coeliac disease.

Objective: The B cell-activating factor of the tumour necrosis factor (TNF) family (BAFF) was recently described as a critical survival factor for B cells, and its expression is increased in several autoimmune diseases. Abnormal production of BAFF disturbs immune tolerance allowing the survival of autoreactive B cells and participates in the progression of B-cell lymphomas. Coeliac disease (CD) is a common autoimmune disorder induced by gluten intake in genetically predisposed individuals, associated with autoantibody production and with an increased risk of lymphoma at follow-up.

Topical treatment of distal active ulcerative colitis with beclomethasone dipropionate or mesalamine: a single-blind randomized controlled trial.

Goals: Therapy for active ulcerative colitis (UC) usually involves rectal formulations of corticosteroids (CS), which are characterized by the risk of systemic steroid-related adverse effects.

Background: To compare the efficacy and safety of the topically acting CS beclomethasone dipropionate (BDP) versus mesalamine (5-ASA) in the treatment of active UC.

Study: Patients with mild to moderate distal active UC were randomized to a 6-week treatment with BDP 3 mg enema o.

Celiac disease and intestinal metaplasia of the esophagus (Barrett's esophagus).

Previous studies on celiac patients demonstrated that exposure to gliadin alters the motility of the upper gastrointestinal tract, leading to increased acid reflux. No literature is available regarding the possible presence of specialized intestinal metaplasia of the esophagus as a consequence of chronic reflux in adult celiac patients. Our purpose was to evaluate endoscopically and histologically the esophagi of a group of untreated celiac patients.

Detection of human papillomavirus DNA and p53 gene mutations in esophageal cancer samples and adjacent normal mucosa.

Background/aim: There is evidence of a possible etiological role of human papillomaviruses (HPVs) in the development of esophageal tumors. Loss of function of the wild-type p53 tumor suppressor gene product by binding to E6 oncoproteins of high-risk HPVs is considered an important event in tumor development. The aim of this study was to verify the prevalence of HPV infection and p53 mutation in esophageal tumor tissue samples and in the adjacent normal mucosa in patients from a high-risk area in Italy.

Acute gastrointestinal bleeding due to Meckel's diverticulum heterotopic gastric mucosa.

Meckel's diverticulum is the most common congenital anomaly of the gastrointestinal tract occurring in approximately 2% of the population. In our retrospective study, we analyzed 58 surgical specimens of Meckel's diverticulum operated on in our hospital. Heterotopic gastric mucosa was found in ten.
