Biochemical and ultrasound aspects in chronic viral hepatitis C patients.

Aim: Biochemical and ultrasound investigations in patients with chronic hepatitis C on a 48-week anti-viral regimen.

Material And Methods: A group of 6 patients, 4 women and 2 men, age range 24-61, were evaluated at the beginning of therapy and compared after 48 weeks of peginterferon alfa-2a and peginterferon alpha-2b regimen at doses established by the National Treatment Program approved by the Romanian National Health Insurance House.

Results: ALT and AST levels have decreased in all patients.

Spiral enteroscopy--a novel method for the management of small bowel diseases--case report and description of technique.

Small bowel diseases are associated with difficult management. Recently, new methods such as single or double balloon enteroscopy and capsule endoscopy have been implemented for the investigation of small bowel, but none is perfect. Spiral enteroscopy seems to be an alternative primising technique for the diagnosis and therapy of small bowel diseases.

[Surveillance of cirrhosis for hepatocellular carcinoma--clinical validation of new serological biomarkers for improved diagnosis].

Unlabelled: Alpha-Fetoprotein (AFP) is a serological marker currently available for the detection of hepatocellular carcinoma (CHC). Its poor sensitivity renders it unsatisfactory for this purpose and suggests the need for additional biomarkers. Squamous cell carcinoma associated antigen (SCCA) is physiologically present in the skin and was recently detected in patients with CHC.

[The relationship between bile reflux and symptoms in patients with gallstones before and after cholecystectomy].

Unlabelled: Many hypotheses affirm that postcholecystectomy syndrome is caused by alterations in bile flow due to the loss of the reservoir function of the gallbladder. We aimed to establish the relationship between postcholecystectomy symptoms and bile reflux.

Material And Method: Thirty patients with gallstones were included in the study.

[Conventional ultrasound in the diagnosis of bile duct calculi].

Unlabelled: Transabdominal ultrasound (US) is one of the most useful methods in the diagnosis of biliary stones.

Aim Of The Study: To appreciate the value of US in the diagnosis of bile duct stones.

Material And Method: 989 patients, explored in the Institute of Gastroenterology and Hepatology Iaşi by US compared with ERCP, MRCP, operative diagnosis and the final diagnostic.

[Radiofrequency ablation of malignant liver tumours].

Both primary and secondary liver tumors are common problems. Hepatocellular carcinoma (HCC) is a tumor with rapid progression and poor prognosis. The standard in the treatment of liver tumors is surgical resection.

[Endo-Lap method in the management of biliary lithiasis (gallbladder and common bile duct)].

Aim: To present the results of the biliary endoscopic approach (ERCP) followed by laparoscopic cholecystectomy (LC) in the management of biliary lithiasis (gallbladder and common bile duct--CBD).

Patients And Method: From 1997 to March 2003 37 patients with biliary lithiasis were treated by endoscopic sphincterotomy (ES) with stone extraction, followed after 24-48 hours by LC. The indications for ERCP were presence of an obstructive jaundice (n=32) and a dilated CBD at the ultrasound examination (n=5).

[Diagnosis of gastric cancer on endobiopsies using the WHO classification].

Gastric cancer (GC), one of the most frequent malignancies can be early detected on endobiopsies. Our aim was to evaluate histologically the GC on endobiopsies, using WHO 2000 and Lauren classifications. The study included 2424 gastric endobiopsies, routine processed; sections stained with HE, Giemsa, PAS and AB.

[Cerebral renin-like activity in different functional conditions (author's transl)].

Using the Boucher micromethod of determining renin activity in the frontoparietal cortex, brain stem, hypothalamus, hypophysis, and epiphysis rat tissue in different functional conditions, we have observed the following: 1 In rats previously treated with an I. V., injection of 1-1.
