Giant secreting adrenal myelolipoma in a man: a case report.

Introduction: Adrenal myelolipoma is a rare, benign neoplasm that is usually asymptomatic, unilateral and nonsecreting. It develops within the adrenal gland and is composed of mature adipose tissue with elements of the hematopoietic series. We describe the case of what is, to the best of our knowledge, one of the largest secreting adrenal myelolipomas reported in the literature.

An atypical case of hepatic cavernous hemangioma.

Introduction: The case of an atypical hepatic angiocavernoma is referred. The lesion, first described as a hypoechogenic area compared to the surrounding parenchyma, with anechogenic shoots inside, suggestive for vascular structures developed one year later into a totally asonic area with frayed margins. This change is very unusual and uncommon for this kind of lesions.

Ultrasonographic study of gallbladder wall thickness and emptying in cirrhotic patients without gallstones.

Background And Aim: Gallbladder wall thickening and impaired contractility are currently reported in cirrhotic patients and often related to portal hypertension and hepatic failure. The purpose of this work was to evaluate, by ultrasonographic method, gallbladder wall thickness and gallbladder emptying after a standard meal in normal subjects and in patients with compensated liver cirrhosis without gallstones.

Methods: Twenty-three patients with Child-Pugh class A liver cirrhosis and twenty healthy controls were studied.

Radioisotopic assessment of gastric emptying of solids in elderly subjects.

Background And Aims: Few studies in literature have investigated the gastric emptying of solids in elderly subjects. We assessed the differences between young and elderly subjects in the gastric emptying rate of solids by a radioisotopic method.

Methods: Two groups of 15 elderly male subjects (mean age 68.

Early invasive diagnostic techniques in pregnant women who are infected with the HIV: a multicenter case series.

Objective: Studies that mostly were conducted before the widespread use of combination antiretroviral treatments have reported that antenatal invasive procedures markedly increase the risk of human immunodeficiency virus vertical transmission. We aimed to evaluate the vertical transmission rate and other maternal and neonatal complications among women who were infected with human immunodeficiency virus who underwent antenatal invasive procedures during the second trimester of pregnancy and who were delivered after the advent of antiretroviral regimens.

Study Design: We conducted a multicenter case series of women who were infected with human immunodeficiency virus who underwent amniocentesis or chorionic villus sampling or cordocentesis during the second trimester of pregnancy and who were delivered after January 1, 1997.

Pattern of gastric emptying in functional dyspepsia. An ultrasonographic study.

We assessed the ultrasonographic pattern of gastric emptying in patients with functional dyspepsia, evaluating its relationship with symptoms. Twenty dyspeptic patients, with slight (group A) and severe (group B) symptoms, and 10 controls (group C) underwent ultrasonographic study of gastric emptying by measuring postprandial variations of the antral area at regular intervals. The time at which the antral area returned to the basal value was assumed to be the final emptying time.

Gallbladder and gastric emptying: relationship to cholecystokininemia in diabetics.

Background: Impaired gastrointestinal and gallbladder motility, as a complication of long-lasting diabetes mellitus, has been ascribed to the possible development of autonomic neuropathy, although the intervention of hormonal factors may not completely be excluded. In this regard, cholecystokinin (CCK), a gut hormone known to regulate pancreatic exocrine secretion, gallbladder contraction, and bowel motility in response to a meal, is impaired in patients with diabetes mellitus. This prompted us to evaluate the relationship between the plasma levels of CCK and gallbladder and gastric emptying in neuropathy-free diabetic patients treated with insulin (group A) or with oral hypoglycemic agents (group B) under basal conditions and in response to a standard test meal.
