RESUMO
BACKGROUND/AIMS: To determine the serum vascular endothelial growth factor receptor-1 (VEGFR-1) levels in hepatocellular carcinoma patients and its correlations with the clinical and laboratory parameters. METHODOLOGY: Serum VEGFR-1 levels were measured in 18 biopsy-proven treatment-naive hepatocellular carcinoma patients (female/male: 5/13; mean age: 59.22 +/- 13.15 years) and in age- and sex-matched healthy controls. Possible associations were also evaluated between serum VEGFR-1 levels and etiology and severity of chronic liver disease, serum alpha-fetoprotein levels, presence of ascites and portal vein thrombosis, and tumor number, size and stage. RESULTS: Serum VEGFR-1 levels were undetectable in all healthy subjects, while all of the patients with hepatocellular carcinoma had increased VEGFR-1 (p < 0.001). Serum VEGFR-1 levels did not correlate with the clinical and laboratory parameters and tumor characteristics in hepatocellular carcinoma. CONCLUSIONS: VEGFR-1 is involved in the regulation of carcinogenesis in hepatocellular carcinoma.

Hepatitis A infection may result in acute hepatitis, and rarely, fulminant hepatitis may ensue. Extrahepatic manifestations of hepatitis A are uncommon. The authors present the case of a 77-year-old male who had development of acute renal failure and pericarditis during the clinical course of acute hepatitis A infection. He died as a result of septic shock on the fifth day of hospitalization. To the best of our knowledge, this is the first report of both these rare and serious complications appearing in the same patient.

Esophageal varice eradication results in gastric hemodynamic changes. The aim of this study was to detect the influence of variceal eradication on portal hypertensive gastropathy (PHG) and fundal varices and to compare the results of two therapeutic methods (endoscopic variceal ligation and endoscopic sclerotherapy). A total of 114 consecutive patients with cirrhosis and portal hypertension who underwent elective endoscopic variceal ligation (EVL) (85 patients) or endoscopic sclerotherapy (EST) (29 patients) for obliteration of esophageal varices were selected for this study. Both groups were compared for PHG and fundal varice formation before and after eradication. Fifty-eight (68.2%) patients in the EVL and 18 (62.1%) patients in the EST group had PHG before esophageal varice eradication (P > 0.05). PHG grade after eradication of esophageal varices by both EVL and EST was significantly higher compared to pre-eradication. PHG grade and aggregation were similar in both groups. Thirty-seven patients (34 F(1), 3 F(2)) in the EVL group and 13 patients (10 F(1), 3 F(2)) in the EST group had fundal varices before variceal eradication (P > 0.05). Fundal varices were detected in 46 (35 F(1), 11F(2)) and 19 (11F(1), 8F(2)) patients in the EVL and EST groups after eradication, respectively. There was a statistically significant increment in occurrence of fundal varices after eradication with EVL and EST groups. There was no significant difference regarding fundal varice development after esophageal variceal eradication in both groups. After varical eradication, PHG was found in 57 (87.7%) and 39 (79.6%) patients with and without fundal varices, respectively (P > 0.05). Esophageal eradication with EVL and EST increases both the incidence and the severity of PHG and fundal varice formation. Both methods have comparable influences on PHG and fundal varices.

Autosomal-dominant polycystic kidney disease is an inherited disorder characterized by multiple cysts in kidneys and other organs. A 63-year-old man was evaluated for the etiology of recurrent pancreatitis and chronic renal failure. Multiple cysts of kidneys, liver, and pancreas and pancreas divisum was diagnosed. Pancreatitis should be included in the differential diagnosis of abdominal pain in patients with ADPKD. Pancreas divisum may be a predisposing factor for acute pancreatitis in these patients.

Our aim was to analyze patients diagnosed with left-sided portal hypertension prospectively and to document the complications at follow-up. Twenty-four patients with isolated splenic vein thrombosis (diagnosed by ultrasonography or angiography or intraoperatively) and/or isolated fundal varices (diagnosed by endoscopy or endosonography) were involved in this study. Demographics, clinical presentation, diagnostic and therapeutic procedures, and morbidity and mortality were recorded in their follow-up. There were 11 and 13 left-sided portal hypertension cases associated with pancreatic diseases and nonpancreatic disorders, respectively. Chronic abdominal pain and gastrointestinal bleeding were the two most common complaints. All patients except one had isolated esophageal (2 cases) or fundal (21 cases) varices. Thirteen patients had splenomegaly on ultrasonography. On Doppler sonography, the splenic vein could be evaluated in 21 of the 24 patients (9 and 6 had complete and partial occlusion, respectively, and 6 had patent blood flow). Urgent intervention with therapeutic endoscopy and splenectomy was performed for two patients each. Medical therapy was begun for three patients according to the underlying diseases. Three patients underwent elective surgery. Two patients were lost to follow-up after the first visit and the mean follow-up of the remaining 22 patients after diagnosis of left-sided portal hypertension was 20 months. Only one patient (with pancreas cancer) had gastrointestinal bleeding at follow-up. All patients with pancreas and gastric cancer died within 2-12 months. Left-sided portal hypertension has various etiologies. It may be difficult to diagnose this entity both endoscopically and radiologically. Treatment should be directed at the underlying diseases. Recurrent hemorrhage due to left-sided portal hypertension is not usual and the prognosis depends mainly on the underlying etiology.

Cystic tumors of the pancreas are rare neoplasms. They are more frequently identified given the improvements in imaging techniques. Serous cystadenomas are the most common among cystic neoplasms of the pancreas. In this case report we present a patient who was incidentally found to have a cystic mass in the pancreas during an abdominal imaging done for unrelated reasons and was diagnosed as serous cystadenoma of the pancreas. She was asymptomatic on admission and was operated six years later because of the progressive growth of the tumor during that period. Distal pancreatectomy was performed. Histopathologic examination of the surgery specimen confirmed the diagnosis of serous microcystic adenoma. Despite their rarity, serous cystadenomas should be kept in mind in the differential diagnosis of the cystic lesions of the pancreas. Furthermore, the differentiation of serous cystadenoma from other cystic tumors as well as from non-neoplastic cysts is very important because of the great difference in their management.

OBJECTIVE: To report a new case of probable alfuzosin-induced hepatitis. CASE SUMMARY: An 80-year-old man was evaluated because of jaundice and pruritus. He was diagnosed as having Child-Pugh A chronic liver disease due to hepatitis B virus. Other etiologies of hepatitis were appropriately ruled out, and the hepatitis B was non-replicative. Therefore, elevated liver enzyme levels were ascribed to alfuzosin treatment. DISCUSSION: Although alfuzosin-related mixed-type hepatotoxicity has been previously reported, this is the first published case describing probable hepatocellular-type hepatotoxicity resulting from use of alfuzosin in a patient with underlying chronic liver disease. According to the Naranjo probability scale, alfuzosin was a probable cause of the hepatotoxicity. The mechanism of alfuzosin-induced liver damage is unknown. Several features, such as absence of predictable dose-dependent toxicity of alfuzosin in previous studies and absence of hypersensitivity manifestations in our case, are suggestive of a metabolic type of idiosyncratic toxicity. CONCLUSIONS: Alfuzosin rarely causes hepatotoxicity; however, clinicians must be alert for this adverse effect while using alfuzosin.

Isolated obstruction (mainly due to thrombosis) of the splenic vein usually results in left-sided portal hypertension and isolated fundal varice formation. This syndrome is a rare cause of gastrointestinal bleeding. Pancreatic diseases are among the most common etiologies of splenic vein obstruction. Renal disorders are rarely reported as a cause of splenic vein thrombosis. In the present article, a case of a 26-year-old woman with a perirenal abscess presenting with gastrointestinal bleeding as a complication of an isolated splenic vein thrombosis is described. The thrombosis could not be visualized with ultrasonography and angiography because of its extremely proximal localization. Fundal varices disappeared following splenectomy and nephrectomy. Follow-up at one year revealed the patient to be well both clinically and endoscopically.
