zymogen/abdominal pain

Recurrent abdominal pain (RAP) is a common, frustrating problem in childhood. A commonly mentioned cause has been acid hypersecretion without evidence of actual ulceration. Recently, a radioimmunoassay specific for group I pepsinogens (PgI), one of two immunochemically distinct groups of human

Pancreatoblastoma is an extremely rare pancreatic tumor in childhood, comprising 0.5% of pancreatic non-endocrine tumors. It mostly affects children of under 8 years old without special sexual predilection. Abdominal mass is the dominant clinical feature and abdominal X-ray, sonography, UGI series,

We report herein the clinicopathological, immunohistochemical and ultrastructural studies on 13 female patients and one male patient with papillary cystic tumors of the pancreas. Their ages ranged from 12 to 60 (mean 25) years. Most patients complained of abdominal mass or abdominal pain. Following

BACKGROUND Glycoprotein 2 (GP2), the pancreatic major zymogen granule membrane glycoprotein, was reported to be elevated in acute pancreatitis in animal models. METHODS Enzyme-linked immunosorbent assays (ELISAs) were developed to evaluate human glycoprotein 2 isoform alpha (GP2a) and total GP2

BACKGROUND Pancreatoblastoma is a rare pancreatic tumor with distinct acinar and squamoid cell differentiation that generally affects infants and young children. Just over 50 cases have been reported in the literature. METHODS Five cases of pathologically proven pancreatoblastoma treated at Seoul

Acute pancreatitis (AP) is a serious illness, defined as acute inflammation of the pancreas, which can result in damage to the surrounding tissue and other organ systems. It is considered as a set of dynamic, local and systemic pathophysiological changes, caused by sudden rush of lithic pancreatic

Ten adolescent and young adults with cystic fibrosis (CF) have had well-documented recurrent attacks of acute pancreatitis. The diagnosis of CF in each patient was delayed because they did not have pancreatic insufficiency. The diagnosis of CF was documented by the typical pulmonary involvement and

Solid and cystic tumor (SCT) of the pancreas predominantly occurs in women, and the occurrence in men is extremely rare. We experienced a male case of SCT. A 38-year-old man was admitted with the complaint of upper abdominal pain. CT scan showed the presence of a mass in the head of the pancreas.

We describe the clinical, cytological, histological, and immunohistochemical features of primary and metastatic pancreatoblastoma (PBL), a rare primary pancreatic malignancy of both adults and children. An 18-yr-old male patient presented with abdominal pain, weight loss, and diarrhea and had a 9-cm
