BACKGROUND & AIMS Pouchitis is the major long-term complication after ileal pouch-anal anastomosis for ulcerative colitis. Most patients have relapsing disease, and no maintenance treatment study has been performed. We evaluated the efficacy of a probiotic preparation (VSL#3) containing 5 x 10(11) per gram of viable lyophilized bacteria of 4 strains of(More)
BACKGROUND The benefit of neoadjuvant chemoradiotherapy in oesophageal cancer has been extensively studied but data on survival are still equivocal. OBJECTIVE To assess the effectiveness of chemoradiotherapy followed by surgery in the reduction of mortality in patients with resectable oesophageal cancer. METHODS Computerised bibliographic searches of(More)
BACKGROUND Although 5-aminosalicylic acid (5-ASA) oral compounds are the standard maintenance treatment for ulcerative colitis in remission, some patients cannot use them because of side-effects. Clinical and experimental observations have suggested the potential role of probiotics in inflammatory bowel disease therapy. AIM To evaluate the effects on(More)
BACKGROUND & AIMS We have recently documented the efficacy of a highly concentrated probiotic preparation (VSL#3) in the prevention of flare-up in patients with chronic pouchitis. The aim of this study was to compare probiotic therapy with VSL#3 versus placebo in the ability to prevent the onset of acute pouchitis during the first year after ileal(More)
OBJECTIVES Promising results from clinical studies on the effect of probiotics as maintenance therapy in inflammatory bowel disease and in the prevention of onset of pouchitis ask for studies to unravel the still poorly understood mechanism of action of probiotics. METHODS To evaluate whether the probiotic bacteria that were used in the clinical studies(More)
Ulcerative colitis is a chronic in ̄ammatory disease of the large intestine, characterised by alternate phases of activity and remission. Its aetiology is unknown, but circumstantial evidence incriminates luminal bacteria and their products in its pathogenesis [1, 2]. Rifaximin (INN) is a rifamycin derivative and its antimicrobial spectrum includes aerobic(More)
BACKGROUND Mesalazine suppositories at 500 mg b.d. are a safe and effective treatment for patients with ulcerative proctitis or distal proctosigmoiditis. Recently a mesalazine 1 g suppository (Pentasa) has been developed. METHODS Fifty patients with active ulcerative colitis extending not beyond 20 cm from the anus on sigmoidoscopy, participated in a(More)
We report a patient who presented with the clinical features of obturator mononeuropathy. Abdomino-pelvic computed tomography revealed a fusiform mass in the right perivesical space; magnetic resonance imaging (MRI) showed characteristic "coaxial-cable-like" appearance in cross-section and "spaghetti-like" appearance in longitudinal section, pathognomonic(More)
Bacteria are present throughout the gastrointestinal tract, but their pattern and concentration vary greatly. Probiotics are living organisms that supply beneficial health effects to the host. So far the beneficial effects of probiotics have been shown, almost exclusively, under poorly defined experimental conditions. There are little convincing data from(More)
The cortical silent period (CSP) following transcranial magnetic stimulation (TMS) was evaluated in a patient with a dysembrioplastic neuroepithelial tumor (DNET) in the lateral portion of the right superior frontal gyrus (SFG) who suffered from supplementary sensorimotor area (SSMA) seizures. CSP duration was shortened on the affected side. Ipsilateral(More)
