Gallstones, development

Liver and Gallbladder. High dosages of oral estrogens have been reported to increase the risk for jaundice, cholestatic hepatitis, gallstones, and hepatic vein blood clots. Estrogens promote the development of hepatic neoplasms associated with increased hepatic cell regenerative activity (186,187). 

One other unique use of MTBE is a medical procedure for the removal of gallstones. This alternative to gallbladder surgery was developed at the Mayo Clinic, and takes advantage of MTBE s capabiUty to quickly dissolve cholesterol. A small incision is used to inject a small amount of MTBE direedy into the gallbladder, and the gallstone can then be removed in solution form (28). 

Excessive secretion of gastric acid, associated with Helicobacter pylori infection, can result in the development of gastric and duodenal ulcers small changes in the composition of bile can result in crystallization of cholesterol as gallstones failure of exocrine pancreatic secretion (as in cystic fibrosis) leads to undernutrition... 

The variant was found In a 22 year old woman with chronic hemolytic anemia characterized by a persistent retlculocytosls, development of gallstones requiring cholecystectomy, frequent episodes of jaundice, dark urine, and falling PCV value. Her mother, maternal grandfather, and sister have a similar clinical picture In all patients red cell enzymes are elevated with a retlculocytosls of about 10%, and 2,3-DPG levels are normal ... 

HbSS) hallmark of SCD Chronic hemolytic anemia is common Patients may develop infarction of the spleen, liver, bone marrow, kidney, brain, and lungs Gallstones and priapism also may develop Slow healing lower extremity ulcers may develop usually after infection or trauma Hgb 7-10 g/dL (70-100 g/L or 4.4-6.2 mmol/L)... 

Gallstones are a common clinical finding in Western populations, the prevalence rate in Europe being 10-15%. Whilst 80% of cases are asymptomatic from their gallstones, 2% develop complications such as cholecystitis and require surgery. ... 

This profile of changes was comparable to that seen in patients with conventional cholesterol gallstone disease, the only difference being that, as a result of OT, the chemistry probably developed in days or weeks, as opposed to months or years in the case of spontaneous gallstone formation. ... 

In London, the Guy s Hospital group d wished to see if they could extrapolate validly from OT-treated acromegalic patients to those with sporadic gallstone disease. They also wished to study further the mechanism whereby prolongation of colonic transit might influence DCA metabolism, biliary cholesterol secretion and saturation, and therefore the risk of cholesterol gallstone formation. To study this, Thomas et developed a working hypothesis... 

Probability of developing gallstones increases with age, obesity, and a high fat diet and is more prevalent in fair-skinned people of European descent, suggesting a genetic component. 

Gallstones are a common complication of HS, and most patients eventually develop them they are rarely found in children, and their incidence increases with age. Since gallstone colic (severe convulsive abdominal pain) and cholecystitis (inflammation of the gall bladder) are quite common, it is desirable that patients with HS should be periodically examined by abdominal ultrasound. 

Patients with mild cases of HS often do not need any treatment. However, these patients should be watched carefully for the development of hemolytic or aplastic crisis. Splenectomy is the treatment of choice in moderate-to-severe HS cases. In general, splenectomy is indicated in patients who are continuously anemic or who have a history of gallstone colic or repeated crises. The clinical results of splenectomy for HS are almost uniformly excellent. However, splenectomy in very young children should be postponed to later in childhood because splenectomized infants are more susceptible to serious and potentially lethal infections than are older children and adults. At the time of splenectomy, it is important to identify and remove any accessory spleen otherwise, the operation will...

Scorbutic guinea pigs develop hypercholesterolemia, which may lead to the development of cholesterol-rich gallstones. This is largely the result of impaired activity of cholesterol 7-hydroxylase, which is an ascorbate-dependent enzyme (Section 13.3.8), resulting in reduced oxidation of cholesterol to bUe acids. There is no evidence that increased intakes of vitamin C above requirements result in increased cholesterol catabolism.
