Histopathologic damage, serum HBV DNA levels, and IH HBV replication markers have a more complex and dynamic process. However, both serum and IH HBV replication markers provide important knowledge about the activity of the disease.

AIM:To evaluate the therapeutic role of caffeic acid phenethyl ester (CAPE) in a rat model of ceruleaninduced acute pancreatitis (AP). METHODS:Seventy male Wistar albino rats were divided into seven groups. Acute edematous pancreatitis was induced by subcutaneous cerulein injection (20 μg/kg) four times at 1-h intervals. CAPE (30 mg/kg) was given by subcutaneous injection at the beginning (CAPE 1 group) and 12 h after the last cerulein injection (CAPE 2 group). Serum amylase, lipase, white blood cell count, and tumor necrosis factor (TNF)-α levels were measured, and pancreatic histopathology was assessed. RESULTS:In the AP group, amylase and lipase levels were found to be elevated and the histopathological evaluation showed massive edema and inflammation of the pancreas, with less fatty necrosis when compared with sham and control groups. Amylase and lipase levels and edema formation decreased significantly in the CAPE therapy groups (P < 0001); especially in the CAPE 2 group, edema was improved nearly completely (P = 0001). Inflammation and fatty necrosis were partially recovered by CAPE treatment. The pathological results and amylase level in the placebo groups were similar to those in the AP group. White blood cell count and TNF-α concentration was nearly the same in the CAPE and placebo groups.

Abdominal tuberculosis is still a medical problem in developing countries. The clinical presentation of tuberculous (TB) peritonitis may be similar to that of peritoneal carcinomatosis. Therefore, its diagnosis is rather difficult only with laboratory investigations. Ascitic fluid adenosine deaminase (ADA) activity has been proposed as a useful diagnostic test in tuberculous peritonitis, as many studies reported high ADA levels in TB peritonitis. On the other hand, ADA activity is usually lower in peritoneal carcinomatosis and malignant ascites. This study described a patient with non-Hodgkin lymphoma with elevated (67 U L(-1)) ADA levels and clinical signs mimicking peritoneal tuberculosis. On admission, this study focused on the high value of ADA in ascites and strongly suspected TP. Although anti-tuberculous agents were initiated, his general condition did not improve. Finally, laparoscopic peritoneal biopsy was performed and non-Hodgkin lymphoma diagnosed. In the light of these findings, ADA level may not reflect TB peritonitis in the absence of histopathological examination. Therefore, non-Hodgkin lymphoma should be kept in mind in the differential diagnosis in patients with high ascitic fluid ADA levels and in non-responders to anti-tuberculosis treatment.

Multiple myeloma is a neoplasm of mature and immature plasma cells. A 50-year-old woman with lumbago, dysphagia, and left arm pain was presented. Upper endoscopical examination was performed. There was an exudate-covered ulcer in the distal esophagus, located at 30-32 cm from the incisors, covering the whole mucosa. Histopathological examination of the specimens obtained from the lesion showed the involvement of plasma cells consistent with multiple myeloma of IgG kappa subtype. Esophageal involvement of multiple myeloma should be kept in mind in patients presenting with dysphagia.
