Abstract
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. CASE PRESENTATION The case of a 74-year old caucasian male, complaining of slight dyspeptic symptoms (post-prandial fullness and bloating) is referred. The routine blood tests were all normal. Abdominal ultrasound showed a large, roughly round-shaped lesion (diameter 14 cm) in the VIII hepatic segment diagnosed as hepatic angiocavernoma, which turned unexpectedly in a cystic like lesion one year later. CONCLUSION The atypical angioma's degeneration could account for one of the causes of the patient's exitus. It could be related to blood seizure by the large hepatic angioma due to the intratumoural haemorrhage.

Abstract
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 68.20 years and 77.26 years, respectively) and a group of young male subjects (mean age 30.23 years) underwent a radioisotopic study of gastric emptying after eating a radiolabeled solid meal. Half-time of gastric emptying (T1/2) and emptying index (EI), i.e. rate of gastric emptying at 120 min, were measured with two opposing detectors connected to a computerized rate-meter. Results are expressed as means +/- SD. RESULTS Significantly different values were obtained in the two groups both at T1/2 (183+/-88 and 195+/-75, respectively) and EI (0.40+/-0.3 and 0.36+/-0.4), compared with young subjects (T1/2=53+/-23; EI=1.10+/-0.3) (p<0.0001). CONCLUSIONS Gastric emptying of solids is significantly delayed in elderly men; this variable must be taken into account when studies on gastric emptying rates are performed.

Abstract
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. RESULTS Sixty-three of 775 recruited women (8.1%) had performed early invasive diagnostic techniques . This rate has improved progressively from 4% in 1997 to 14%. Two of 60 viable infants (3.3%; 95% CI, 0.6%-10.1%) were infected with the human immunodeficiency virus. This rate did not differ significantly from the transmission rate that was observed in women who did not undergo antenatal invasive techniques (1.7%; P = .30). CONCLUSION The current risk of human immunodeficiency virus vertical transmission that is associated with early invasive diagnostic techniques is lower than previously reported.

Abstract
BACKGROUND The study of gastric emptying rate of solids using radiopaque indigestible solid markers has been a poorly employed technique because some kinds of markers do not leave the stomach at the same time as the meal but during the interdigestive migrating motor complex (IMMC). The aim of this study was to evaluate whether markers of particular shape and size can be successfully employed for this purpose. METHODS Twenty-eight non-ulcer dyspeptic (NUD) patients and 20 healthy volunteers received a standard solid meal (790 Kcal) together with 20 small polyethylene radiopaque cylinders (5 mm x 2 mm in diameter). Gastric emptying rate was evaluated by ultrasound while the emptying of markers was simultaneously followed by X-rays using a brilliance intensifier. RESULTS Final emptying time (FET = time when the antrum area returns to fasting size) of digestible solids was 355+/-35 min in NUD patients versus 265+/-20 min in controls (P < 0.001). The gastric emptying curve of digestible solids correlated with emptying of markers both in NUD patients (r= +0.96) and in controls (r= +0.93). CONCLUSIONS The assessment of gastric clearance of radiopaque cylinders of 2 mm x 5 mm in size is a reliable tool for the study of gastric emptying rate of digestible solids. This is a readily available and easily performed test in any radiology unit.

Abstract
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. The final emptying time was significantly longer in both group A (294 +/- 42 min) and group B (340 +/- 36 min) compared to controls (244 +/- 21 min), but no significant difference was observed between them. A significantly (P < 0.05) greater dilation of the antral area was found at 50 min in group B compared to group A patients. A different pattern of antral motor function rather than a delay of gastric emptying correlates with the severity of symtoms in dyspeptic patients.

Abstract
OBJECTIVE Options for human immunodeficiency virus-1-infected women who are already receiving antiretroviral medications when they become pregnant include the continuation or discontinuation of the therapy during the first trimester. These two strategies are compared in terms of plasma human immunodeficiency virus viral load and CD4 cell count. STUDY DESIGN Seventy women who attended the II Department of Obstetrics and Gynecology were identified. Four different periods for laboratory evaluations were decided: presuspension, suspension, second trimester, and third trimester. RESULTS Thirty-two women (46%) discontinued antiretroviral therapy; 38 women (54%) did not. Whereas plasma HIV virus viral load and CD4 cell count did not significantly vary during pregnancy in patients who did not interrupt the therapy, these two variables were influenced significantly by the discontinuation of treatment (P<.001 for both). Human immunodeficiency virus viral load increased during the suspension period and regressed promptly to basal levels as soon as the therapy was reintroduced. A transitory decrease in CD4 cell count was also documented, but the recovery tended to be slower. CONCLUSION The suspension of combination antiretroviral therapy during the first trimester of pregnancy transiently corresponds to an increase in human immunodeficiency virus viral load and a decline of CD4 cell count.

Abstract
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. Methods: Plasma CCK was measured by radioimmunoassay. Gastric and gallbladder emptying were evaluated ultrasonographically. Results: Plasma CCK levels were significantly lower in both groups of diabetics than in healthy controls during a fast and in response to a standard meal. However, meal ingestion was able to evoke a pattern of CCK response in both groups of diabetic patients similar to that seen in controls. Fasting gallbladder volume was higher in patients with diabetes than in controls, whereas the percentage of emptying was lower in patients of both groups. Gastric final emptying time was significantly longer in both groups of diabetics than in controls. Conclusion: This study shows that patients with diabetes have lower plasma levels of CCK, which may explain their relatively hypotonic gallbladder and reduced gastric motility.

Abstract
BACKGROUND In recent years, combination antiretroviral therapy has substantially improved the prognosis of human immunodeficiency virus type-1 (HIV-1) infection. However, at present, information regarding the effects of these regimens during pregnancy is limited. METHODS Side-effects, vertical transmission rate and neonatal outcome associated with different combination therapies were evaluated retrospectively in a consecutive series of 100 women who attended the II Department of Obstetrics and Gynecology for the management of HIV-1 infection in pregnancy. RESULTS Antiretroviral treatment was initiated at a median of 16 weeks gestation with a range from pre-pregnancy until 31 weeks gestation. Twentythree women continued their pre-pregnancy therapy during the first trimester of gestation. Protease inhibitors were incorporated in 23 of the final therapeutic regimens. Twentyfive women did not receive zidovudine. Most women (97) delivered by Caesarean section and none breast-fed. Prematurity rate for the entire series was 19%. When women who actively used illicit drugs were excluded, only seven of 69 (10%) women were found to deliver prematurely. The use of protease inhibitors was limited by an elevated frequency of severe gastrointestinal disturbances. The rate of congenital malformations did not appear to differ significantly from that reported in the literature for the general population. Only one of 102 live newborns was found to be HIV-1-infected (1.0%, 95% confidence interval; 0.3-4.6%). CONCLUSIONS The present findings confirm the remarkable efficacy of combination antiretroviral therapy, Caesarean section and refraining from breast-feeding in lowering the rate of vertical HIV-1 transmission. Moreover, they are suggestive that combination antiretroviral therapy may not be related to major neonatal toxicity. The necessity to discontinue the therapy during the first trimester of pregnancy and to systematically incorporate zidovudine into combination regimens is discussed.

Abstract
BACKGROUND The aim of this study is to clarify the prevalence of gallbladder benign neoplasms, their ultrasonographic appearance and their relationship with gallbladder lithiasis and cancer. METHODS This study was carried out on 9000 consecutive patients having ultrasound of upper abdomen. Only adenomas and papillomas are considered as true benign neoplasms of the gallbladder. Adenomiomatosis and cholesterol polyps, often erroneously labelled as benign neoplasms, were excluded. Patients were followed-up by ultrasound every three months up to two years. RESULTS The prevalence of benign neoplasms was 1.19%. Papillomas were found more frequently than adenomas both in males (68.51%) and in females (94.33%). Gallstones were not concomitant with benign neoplasms in any case. Neither stones nor growth of gallbladder benign neoplasms were recorded within the two-year follow-up period. CONCLUSIONS Papillomas were more frequent than adenomas. No gallstone was concurrent with gallbladder benign neoplasms in our series. However, when gallstones are evidenced at ultrasound, further attention is recommended to discover probable concomitant neoplasms. Papillomas and adenomas more than 1 cm in diameter should be quarterly followed-up, while smaller masses could be six-monthly controlled. Surgery should be indicated for large-sized or rapidly growing masses because of the risk for cancer development.

Abstract
RATIONALE AND OBJECTIVES To assess and compare gastrointestinal (GI) rates in young and aged men under homogeneous conditions of weight and dietetic habits. METHODS Gastric emptying time was evaluated by ultrasound. GI transit time was studied radiologically using radiopaque markers. RESULTS Final gastric emptying time in elderly subjects was 335 +/- 31 minutes (mean +/- SD) versus 245 +/- 25 minutes in young subjects (P < 0.001). Total GI transit time showed no significant difference between the two groups. Intestinal transit time includes both small bowel and colonic transit; small bowel and colonic transit was not separated in this study. CONCLUSIONS Delayed gastric emptying of solid foods could result from progressive autonomic nerve dysfunction occurring with aging. The stomach does not seem to be the segment of the digestive tract that is primarily responsible for the alteration of total GI time.

Abstract
Gastric emptying can be modified by different physiologic conditions such as aging, menstrual cycle and pregnancy. Few studies in the literature have compared the gastric emptying rate of solid meals in normal subjects of varying size. The purpose of this work is to evaluate the gastric emptying rate of solid meals to determine whether body mass index (BMI) and gastric emptying rate correlate. Both ultrasonographic and scintigraphic techniques have been employed. Twenty-four healthy male subjects, divided into two groups, participated in the study. Our results demonstrate a significant correlation between gastric emptying and BMI. We conclude that variability of BMI must be taken in account when measurements of gastric emptying of solid food are performed.

Abstract
RATIONALE AND OBJECTIVES Gallbladder wall thickness was measured by ultrasound in 16 patients with ascites caused by liver cirrhosis and in 16 noncirrhotic patients with ascites. This study was performed to evaluate if gallbladder wall thickening could differentiate cirrhotic ascites from ascites due to other causes. METHODS Gallbladder thickness was measured by duplex ultrasound in 16 cirrhotic patients with ascites and in 16 noncirrhotic patients with ascites. Measurements of portal vein flow and serum albumin also were performed. RESULTS Gallbladder wall thickness was 0.76 +/- 0.21 cm in cirrhotic patients and 0.24 +/- 0.09 in noncirrhotic patients (P < 0.001, Student's t test for unpaired data). Gallbladder wall thickening was significantly more frequent in patients with cirrhotic ascites than in patients with noncirrhotic ascites (P < 0.001, chi-square test). CONCLUSIONS The authors feel that the ultrasound finding of gallbladder wall thickening in patients with ascites is highly predictive of liver cirrhosis diagnosis.

Abstract
We evaluated the results of a 12-month treatment using different regimens of omeprazole at the dose of 20 mg daily (three day week-end treatments and every other day) and of 150 mg nocte of ranitidine on Helicobacter pylori status and on preventing duodenal ulcer relapses in 140 Helicobacter pylori positive patients with healed duodenal ulcer. Only every-other-day omeprazole suppresses Helicobacter pylori after 3 month therapy (p < 0.001), after 6 months (p < 0.001) and 12 months (p < 0.05). After 3 months (T1) no significant effectiveness was found in the prevention of ulcer relapses by omeprazole and ranitidine. After 6 months (T2) a significant reduction of relapses (p < 0.05) was recorded when comparing every- other-day omeprazole to the weekend regimen. After 12 months every-other-day omeprazole treatment significantly reduced the relapses compared with the week-end therapy (p = 0.05) and with ranitidine (p < 0.05).

Abstract
Gastric emptying of digestible and indigestible solids has been simultaneously evaluated in healthy humans. Gastric emptying of indigestible solids occurs simultaneously during the emptying of digestible solids. The knowledge of the mechanism responsible for gastric emptying of both digestible and indigestible solids may contribute to improve physiologic insight in this field and to develop further clinical applications.

Abstract
The pancreatic duct or at least parts of this structure can be demonstrated today by sonography in 50-82% according to various authors. We have measured the caliber of the sonographically visualized pancreatic duct in 20 normal subjects after physiological stimulation with meal. The mean caliber of the duct markedly increased after meal. During dilatation a longer segment of duct is more clearly visualized. It is possible to document an increase of caliber of Wirsung duct "in vivo" as an evident sign of pancreatic secretion.

Abstract
We measured simultaneously gastric emptying of digestible and indigestible solids in 10 normal subjects and in 14 insulin-requiring diabetic patients. Our results demonstrate that in both diabetics and in controls the gastric emptying of digestible and indigestible solids occurs during the same phase of gastric motor activity, i.e. during the post-prandial period. However, gastric emptying of both digestible and indigestible solids is delayed in diabetic patients compared to controls.

Abstract
The purpose of this work was to evaluate gastric emptying of a solid meal in 20 patients with functional dyspepsia and in 20 healthy controls. Gastric emptying time (T 1/2 = 188.45 +/- 93.79; p less than 0.001 - E.I. = 0.43 +/- 0.16; p less than 0.001) was significantly delayed in patients with functional dyspepsia compared with controls. The conclusion is drawn that either antral motor activity or antral-pyloric-duodenal motor activity is impaired in such patients.
