Transfer dysphagia is difficulty in propelling the food from the mouth to the esophagus or initiation of the act of swallowing (see MedLink Neurology article Dysphagia). We perform tests to help diagnose conditions which impair the function of the gullets muscle and identify any abnormalities that are preventing normal swallowing of foods. Neurodegenerative disorders. A pilot trial (NCT00977197) showed that pregabalin, an antiepileptic used for the treatment of diabetic neuropathy and fibromyalgia, has shown some efficacy in irritable bowel syndrome for relief of abdominal pain and diarrhea (54). The investigators found that mice pretreated with the candidate probiotic Bacteroides fragilis or polysaccharide A survived a lethal herpes simplex virus infection whereas mice pretreated with a placebo did not survive despite the fact that both groups were given acyclovir, an antiviral that is the standard of care for herpes simplex virus encephalitis. Gastroesophageal reflux disorder.
