PURPOSE To introduce aplasia or hypoplasia of the vestibulocochlear nerve (VCN) as a possible cause of hearing loss and to identify the magnetic resonance (MR) imaging characteristics of this entity. MATERIALS AND METHODS In seven patients with congenital deafness or unexplained sensorineural hearing loss, MR imaging enabled diagnosis of aplasia or(More)
INTRODUCTION Transanal endoscopic microsurgery for rectal adenomas is safe and has low recurrence rates. However, the feasibility of the procedure for all rectal adenomas is unclear. This issue was investigated prospectively. METHODS From 1996 to 2007, 353 consecutive rectal adenomas were evaluated according to a standard protocol. Transanal endoscopic(More)
INTRODUCTION Severity of mucosal inflammation is shown to be associated with Barrett's esophagus (BE) development in animals. It has therefore been postulated that a strong pro-inflammatory host response predisposes to BE. AIM To determine the impact of cytokine gene polymorphisms on the development of BE. METHODS The multiplex SNaPshot method was used(More)
Using cutaneous electrodes an electrogastrographic study was made of gastric myoelectrical activity in both the fasting and postprandial states in 48 patients with unexplained nausea and vomiting and in 52 control subjects. A gastric emptying study, using a radio-labelled solid phase meal, was carried out in 30 of these 48 patients. A follow up study was(More)
BACKGROUND It is an accepted fact that non-steroidal anti-inflammatory drugs (NSAIDs) are potent inhibitors of colorectal carcinogenesis. However, the major disadvantages of NSAIDs are gastrointestinal and renal toxicity. We conducted a prospective pilot study on the effects of the safe salicylic acid derivative, mesalazine, on apoptosis and proliferation(More)
Interdigestive myoelectric activity and mechanical activity were studied simultaneously by means of cutaneous electrodes (electrogastrography) and intraluminal pressure recording, respectively, in 10 healthy male volunteers. The aims of the present study were 1) to describe the characteristics of the electrogastrogram during the different phases of the(More)
BACKGROUND Neoplastic progression of BE towards EAC is associated with increased expression of COX-2. Increased COX-2 expression and enzyme activity is linked to the COX-2 CA haplotype, which consists of two gene polymorphisms in the COX-2 promoter. AIM To study the impact of COX-2 haplotypes on the risk of developing EAC in patients with different forms(More)
BACKGROUND Proton pump inhibitors can be effective as maintenance therapy in reducing the relapse rate of reflux oesophagitis at a dose lower than that used for acute healing. PATIENTS AND METHODS Patients (n=396, 18-88 years old) with healed reflux oesophagitis (grade II or III before healing) were included in this multinational, prospective,(More)
BACKGROUND Irritable bowel syndrome is a common gastrointestinal disorder characterized by abdominal pain and discomfort and altered bowel habit. Antagonism at the 5-HT3 receptor may be of benefit in the treatment of irritable bowel syndrome. AIMS To evaluate the effect of 12 weeks of treatment with alosetron, a 5-HT3 receptor antagonist at doses of 0.1(More)
We conducted a double-blind study comparing two dosage regimens of a prokinetic drug, cisapride (10 mg q.d.s. and 20 mg b.d.), with a low dose of a H2-receptor antagonist (150 mg ranitidine b.d.) in the treatment of 155 patients with reflux oesophagitis as determined by endoscopy. The active treatment took 8 to 12 weeks depending on whether complete healing(More)
