This review of the pathophysiologic basis for gastroparesis and recent advances in the treatment of patients with gastroparesis shows that there are several novel approaches to advance treatment of gastroparesis including diet, novel prokinetics, interventions on the pylorus, and novel forms of gastric electrical stimulation. The field of gastroparesis is likely to advance with further studies,...

The aims of the present study were to identify prognostic factors for systemic sclerosis (SSc)-related interstitial lung disease and to clarify the possible causative role of manometric oesophageal involvement. Consecutive SSc patients underwent pulmonary function tests and oesophageal manometry. They were included in the study if pulmonary function tests were repeated >12 months after baseline...

The aim of this study was to determine the effects and mechanism of synchronized gastric electrical stimulation (SGES) on gastric contractions and gastric emptying. The first experiment was designed to study the effects of SGES on antral contractions in four randomized sessions. Sessions 1 (control) and 2 (atropine) were performed in the fasting state, composed of three 30-min periods (baseline...

Pregnancy has an inhibitory effect on motility of the gastrointestinal tract. The present study was designed to examine the mechanisms responsible for antral and colonic hypomotility in pregnant guinea pigs. Circular smooth muscle cells from the antrum and left colon were isolated by enzymatic digestion with collagenase from pregnant and nonpregnant guinea pigs. Contractile responses to agonist...

BACKGROUND Patients on total parenteral nutrition have an increased risk of developing gallstones because of gall bladder hypomotility. High dose amino acids may prevent biliary stasis by stimulating gall bladder emptying. AIMS To investigate whether intravenous amino acids also influence antroduodenal motility. METHODS Eight healthy volunteers received, on three separate occasions, intrave...

As patients with chronic Chagas disease exhibit morphological and functional changes of the stomach (hypomotility and hypochlorhydria), malnutrition, immunological deficiency and high prevalence of peptic disease associated to Helicobacter pylori infection, the purpose of this study was to evaluate if the prevalence of H. pylori infection in chronic chagasic is higher than in non-chagasic indiv...

OBJECTIVES Eosinophilic esophagitis (EE) is a condition characterized by dysphagia and frequent food impaction in young adults. The aim of our study was to evaluate the clinical aspects, endoscopic features, pH-metric and motility disorders in EE. PATIENTS AND METHODS Adult patients with EE were prospectivity included. Endoscopy with biopsy, stationary esophageal manometry, and 24-hour pH-met...

Although lipid metabolism is thought to be important for the proper maturation and function of spermatozoa, the molecular mechanisms that underlie this dynamic process in the gonads remains incompletely understood. Here, we show that group III phospholipase A2 (sPLA2-III), a member of the secreted phospholipase A2 (sPLA2) family, is expressed in the mouse proximal epididymal epithelium and that...

BACKGROUND/AIMS Chronic intestinal pseudo-obstruction (CIPO) reflects a dysfunction of the visceral smooth muscle or the enteric nervous system. Gastrointestinal manifestations are common in systemic lupus erythematosus (SLE) but CIPO has not been reported. Features of CIPO are reported in five patients with SLE. METHODS From 1988 to 1993, five patients with SLE or SLE-like syndrome were hosp...

Coronoid Hyperplasia (CH) is a non-neoplastic and relatively rare enlargement of the coronoid process that may limit mandibular movement as a consequence of the close association between the hyperplastic coronoid process and the anterior region of the zygomatic bone. Computed tomography (CT) is extremely useful for the observation of this association and plays an important role in diagnosing an...
