Bile duct varices or "pseudo-cholangiocarcinoma sign" in portal hypertension due to cavernous transformation of the portal vein.

A total of 832 patients with portal hypertension resulting from different etiology was studied by ultrasonograph as a screening test. In 17 of the 832 patients, cavernous transformation of the portal vein was detected by means of ultrasonography. We have prospectively studied these 17 patients, and the diagnosis of cavernous transformation was confirmed by portography in all patients. To evaluate how much biliary tract has been affected from cavernous transformation of the portal vein, and to explain the cause of mildly increased alkaline phosphatase and serum bilirubin levels, endoscopic retrograde cholangiopancreatography (ERCP) was performed in 16 of the 17 patients. There were narrowing, irregularity, undulation and nodular extrinsic defects resulting from compression of thrombosis of the portal vein and the collateral vessels, mimicking cholangiocarcinoma spreading along the common bile duct on the extrahepatic biliary tract in all 16 patients who underwent ERCP. Similar ERCP findings were not found in six patients with portal hypertension due to liver cirrhosis. The ultrasonographic, portographic, and ERCP findings corresponded to surgical findings in six patients who had undergone splenectomy for either hypersplenism or bleeding from esophageal varices. The results indicate that cavernous transformation of the portal vein cause the above-mentioned radiographic findings that we propose to call "pseudo-cholangiocarcinoma sign."

Treatment of Behçet disease with indomethacin.

Thirty patients with Behçet disease (BD) were treated with oral indomethacin 25 mg four times daily for 3 months as an open label study. The study population consisted of 13 women and 17 men from 15 to 45 years of age (mean 27 years). At the initiation of the therapy, 28 patients had oral aphthous lesions, 23 had joint involvement, 13 had genital ulcerations, 8 had cutaneous lesions, and 4 had eye involvement. Eighty-eight percent of patients with skin lesions, 80% with joint involvement, 43% with oral aphthous lesions, and 38% with genital ulcerations responded to indomethacin therapy. In three patients indomethacin was changed to the suppository form due to gastrointestinal side effects. Although it is difficult to assess the efficacy of indomethacin in BD because of the intermittent nature of symptoms, the majority of patients showed improvement in their symptoms of arthritis and skin lesions. This study indicates that indomethacin can be used as effective therapy particularly in patients with joint involvement.

Functional asplenia and portal hypertension in a patient with primary splenic hemangiosarcoma.

A 60-year-old man with primary splenic hemangiosarcoma (PSH) presented with weakness, weight loss, abdominal pain, and anemia. Physical examination revealed hepatomegaly, ascites, and firm, huge splenomegaly. Ultrasonography showed many nodular structures characterized by hypoechogenic and hyperechogenic areas. The patient also had portal hypertension, which was confirmed by physical findings and by measurement of portal vein pressure during operation. A liver-spleen scan using Tc-99m sulfur colloid and Tc-99m labeled heat denatured erythrocytes failed to demonstrate any splenic uptake, a reliable feature of functional asplenia. Although on a total body scan with Ga-67 citrate there was no splenic uptake, there was gallium uptake in the liver, where the presence of the metastatic lesion was histopathologically verified and confirmed by operation. There was also uptake in the middle zones of the lungs. Ga-67 citrate imaging appears to be helpful in the diagnosis of metastasis of PSH, and PSH can rarely cause portal hypertension.

Serum bactericidal and opsonic activities in patients with non-alcoholic cirrhosis.

The increased susceptibility to infection suggests that patients with cirrhosis have abnormalities in host defense mechanisms. In the present study, serum bactericidal and opsonic activity were evaluated in patients with non-alcoholic cirrhosis. Seven (28 per cent) of 25 patients had diminished bactericidal activity and 14 (61 per cent) of 23 were found to have reduced opsonic activity. Serum C3, C4, and CH50 concentrations were significantly low in patients with diminished bactericidal activity. There was a strong correlation between complement levels and bactericidal activity. Deficient bactericidal and opsonic activities may explain the increased susceptibility to infections in patients with cirrhosis.

Bactericidal and opsonic activity of ascitic fluid from cirrhotic and noncirrhotic patients.

Cirrhotic patients with ascites are highly susceptible to spontaneous bacterial peritonitis. Patients with ascites due to causes other than cirrhosis very seldom develop peritonitis. The antibacterial activity of these ascitic fluids is not known. The present study was undertaken to evaluate the bactericidal and opsonic activity in ascitic fluid from patients with and without cirrhosis and in normal (nonascitic) peritoneal fluid. Normal peritoneal fluids of 20 control subjects and ascitic fluids of 22 patients with noncirrhotic ascites all had normal bactericidal activity. The bactericidal activity of ascitic fluid was diminished in all 25 patients with cirrhosis (P less than 0.00005 by Fisher's exact test). Similar results were found when opsonic activity was evaluated. Complement and immunoglobulin concentrations in cirrhotic ascites were significantly lower than those in the other two groups. The present study demonstrates that noncirrhotic ascitic fluid has antibacterial activity similar to normal peritoneal fluid, whereas cirrhotic ascitic fluid has a marked reduction of both bactericidal and opsonic activities. These defects may explain the high incidence of peritonitis in cirrhotic patients.

Bronchial asthma associated with intestinal parasites.

Fifty patients with bronchial asthma and 50 normal controls were studied in Hacettepe University Medical Center. Forty per cent of the patients with bronchial asthma and 14% of the controls had ascarides in the stool examinations. The significant difference in these two groups indicates that intestinal parasites, should be looked for in the patients with bronchial asthma.

HB-Ag in sweat.

Thirty patients were studied at the Hacettepe University Medical Center. Ten patients had hepatic cirrhosis, 20 patients had viral hepatitis. HB-Ag in the serum was positive in all patients by the counterimmunoelectrophoresis method. One and a half milliliters of sweat was collected from each patient, dried and dissolved in 0.2 ml. of buffer solution. HB-Ag was positive in all patients by radioimmunoassay method. This study indicates that direct contact is one of the most important factors in the epidemiology of the disease and this may even be more important in asymptomatic carriers.
