[Knowledge, application, and diffusion of results of clinical research: the case of porto-systemic encephalopathy].

The objectives of this survey were to evaluate the medical knowledge, acceptance and application of research results, and to identify the main sources of information in our environment. Portal-systemic encephalopathy (PSE) was the specific health problem addressed. Three hundred seventy-seven attendants to the National Mexican Gastroenterology Week (december 14-19, 1991) were surveyed. The results point out: 1) Gaps in PSE knowledge, since 30% or more incorrect answers were obtained for some PSE manifestations and therapeutic measures; 2) A persistent use of measures with doubtful efficacy, which is exemplified by the regular use of neomycin by (80%) of the respondents, 3) frequent influence of the availability of therapeutic measures (68%), as the satisfaction with therapeutic response (66%) on PSE treatment patterns, and 4) important role of continuing education courses and/or scientific meetings (> 66%) and medical journals (> 57%) as sources of information.

[Nutrition of patients with liver diseases. (lst of 2 parts)].

Diet may be modified and can alter the hepatic function or contributes to maintain it on excellent state. The objective of this paper was to review the recently advances on the clinical aspects of nutrition in chronic liver diseases and the underlying rationale for specific nutritional therapies focusing in the works in Mexico. Original papers in english and spanish informed on Medline until 1994 were included. We also review the national literature about nutrition aspects on liver diseases.

[Laboratory studies and special tests for assessing gallbladder and bile duct function].

We review the pathogenesis of cholesterol gallstones, which occur in five steps: 1) metabolic; 2) chemical; 3) nucleation, 4) growing and maturation of gallstones; 5) clinical. It is emphasized that in the third step it could occur an arenous precipitate formed by cholesterol crystals, calcium bilirrubinate granules, calcium phosphate, or fatty acids anions and calcium, and mucin, called "biliary sludge", which has been associated with cholecystitis and pancreatitis. We describe the gallbladder motor abnormalities that occur during the lithogenesis and the diagnostic approach through scintigraphy and real time ultrasound. We review the pancreatobiliary dyskinesia, a condition associated with the postcholecystectomy syndrome. This later condition can result from anatomic stenosis or dyskinetic dysfunction of the sphincter of Oddi. Likewise, it is pointed out that at the present time, the manometric evaluation of the sphincter of Oddi is the gold standard in the diagnostic approach of this condition.

[Physiology of gallbladder motility and its clinical importance].

The role of gallbladder motility (GBM) in gastrointestinal diseases has been frequently ignored. Recently however, the introduction of new diagnostic methods and data on the normal physiology of gallbladder emptying and refilling have placed this interesting area of gastrointestinal motility where it justly deserves. In this way it has been possible to recognize and further study the pathophysiologic mechanisms involved in some clinical situations with a higher-than expected frequency of gallstones (GS). It has also been possible to identify with more clarity the role GBM has in the chain of events that lead to GS development and thus, to plan prevention or therapeutic strategies. The discovery of new drugs with effects on GBM have also permitted to further advance in the knowledge of normal physiologic mechanisms and to have access to possible future treatments. Also pathologic entities have been clearly defined, such as chronic acalculous cholecystitis. In this review we present recent knowledge on normal GBM physiology and its clinical applications as well consequences of its dysfunction.
