Cryoglobulinemia due to chronic viral hepatitis infections is not a major problem in clinical practice.

Background: Essential mixed cryoglobulinemia (EMC) is a systemic disease frequently associated with chronic viral hepatitis. This study was conducted in order to assess the prevalence of EMC in patients with hepatitis B virus (HBV) or hepatitis C virus (HCV) infections. We also evaluated the possible associations of EMC with (1) the clinical, virological, and histological status of liver disease; (2) the presence of EMC-related symptoms; and (3) the response rate to interferon-alpha (IFN-alpha) treatment, in an attempt to address whether EMC is a major problem in hepatitis patients.

Amount and composition of bone minerals in chronic liver disease.

Alterations in bone mineral are a common complication of chronic liver disease. The aim of the current study was to assess bone mineral status in patients with chronic liver disease not treated with corticosteroids and to investigate any possible correlation with the histological stage of liver disease. Bone mineral status in 27 patient with chronic active hepatitis, and 17 with active cirrhosis was compared to that of matched controls.

Prevalence of hepatitis B and C viruses infection in chronic alcoholics with or without liver disease in Ioannina, Greece: low incidence of HCV infection.

Intravenous heroin abusers comprise a high risk group for hepatitis B and C viruses (HBV and HCV) infection. Chronic alcoholics with liver disease (LD) also comprise a high risk group for HBV infection whereas the frequency of antibodies to HCV (anti-HCV) ranges from 27-42.6%.

Pathogenetic mechanisms of hypomagnesemia in alcoholic patients.

The aim of our study was to describe the possible pathophysiologic mechanisms of hypomagnesemia in alcoholic patients. A total of 127 chronic alcoholic patients admitted to our university hospital for causes related to alcohol abuse were studied. Hypomagnesemia was the most common electrolyte disturbance observed in 38 patients (29.

Hidradenitis suppurativa in Crohn's disease. A further support to this association.

A patient with Crohn's disease (CD) subsequently developed the clinical and histological features of hidradenitis suppurative (HS). So far, only five cases with such an association have been reported. Azathioprine (150 mg/d) and methylprednisolone (16 mg/d) for CD combined with isotretinoin (0.

Incidence of inflammatory bowel disease in north west Greece: rarity of Crohn's disease in an area where ulcerative colitis is common.

Ulcerative colitis (UC) and Crohn's disease (CD) are generally regarded as diseases of affluent societies of the Western World, although their frequency in less affluent areas is not well established. This retrospective study therefore, assesses the incidence of UC and CD in a semirural area of north west Greece during the 10 year period 1982-1991. By the 31 December 1991, 61 patients had met standard diagnostic criteria for UC (annual incidence 4.

Acid-base and electrolyte abnormalities in alcoholic patients.

This study was undertaken to analyze the acid-base and electrolyte abnormalities and the pathogenetic mechanisms involved in alcoholic patients admitted to our department for causes related to alcohol abuse. We studied 79 alcoholic patients aged 31-78 years. None had any other disease or was receiving drugs influencing acid-base balance and electrolyte parameters.

Water as contrast medium for computed tomography study of colonic wall lesions.

A tap water enema combined with intravenous iodine contrast medium was used for computed tomographic (CT) study of the entire clean colon in 35 patients. Thirty of them showed a high suspicion of rectal, colon, or cecal pathology at either clinical examination, barium enema study, or endoscopy. The remaining five patients were examined for suspected local recurrence of carcinoma.

Use of water or air as oral contrast media for computed tomographic study of the gastric wall: comparison of the two techniques.

Thirty-four patients with a high suspicion of gastric lesion at endoscopy were studied by two computed tomographic (CT) techniques: one using a gas-producing agent and the other using water as an oral contrast media. Intravenous contrast medium was also given in all patients who underwent the water technique. Final histologic proof was obtained either by endoscopy or at surgery.
