BACKGROUND Provocation tests in patients with food-dependent exercise-induced anaphylaxis (FDEIA) are often negative, even after a sufficient quantity of the implicated food and exercise have been taken. OBJECTIVES To investigate the effect of aspirin in provocation tests and in skin prick testing (SPT) of patients with FDEIA. Gluten as a major allergen(More)
AIM To clarify whether hepatocellular carcinoma (HCC) originates from hepatic progenitor cells and whether there is any correlation with the clinicopathologic factors of HCC, we reviewed 217 resected HCC specimens. METHODS Immunohistochemical examination of cytokeratin (CK) 7, CK19, CD34, and CD117 (c-KIT) was performed. Overexpression of CK7 and CK19(More)
Although there have been many studies of the risk factors for recurrence after resection of hepatocellular carcinoma (HCC), the subjects were patients with various viral status in the previous studies, and hepatitis C viremia has not been evaluated. We investigated risk factors, including hepatic C viremia and histologic findings of noncancerous hepatic(More)
The frequency of lymph node (LN) metastasis in patients undergoing surgery for hepatocellular carcinoma (HCC) has rarely been studied. We evaluated the clinicopathologic characteristics and outcomes of six patients with nodal metastases from HCC among a total of 504 patients who underwent hepatic resection for HCC in our department over a 16-year period.(More)
In an attempt to define better surgical strategies for patients with hepatocellular carcinoma (HCC), we conducted a retrospective analysis of 452 patients who underwent hepatic resection at our institute during a period of 15 years. The patients were divided into two groups: group A, comprising 188 patients who underwent hepatic resection before 1988, and(More)
The presence of small additional hepatocellular carcinomas (HCCs) undetectable before hepatic resection is a crucial topic for hepatic surgeons. We assessed the incidence of pathologically diagnosed multiple HCCs in 267 patients who underwent hepatic resection for HCC. Ninety-five additional HCC nodules were detected in 72 of the patients (27%). The(More)
Percutaneous transhepatic portal vein embolization (PTPE) produces regenerative hypertrophy in the nonembolized part of the liver, but the regenerative capacity after PTPE in patients with chronic hepatitis is unknown. We studied 34 patients with hepatocellular carcinoma and chronic hepatitis who underwent PTPE at the right portal vein. Hepatic lobular(More)
A 65-year-old man with chronic hepatitis C showed a markedly elevated serum alpha-fetoprotein concentration. Computed tomography revealed a huge tumor occupying the entire right hepatic lobe. Three months later, the tumor regressed spontaneously from 12 cm to 7 cm in diameter without any medical treatment. A right hepatic lobectomy was performed 4 months(More)
BACKGROUND The prognosis of hepatocellular carcinoma originating in or mainly involving the caudate lobe (caudate HCC) is generally poor. We reviewed the clinicopathologic findings of patients who underwent liver resection of caudate HCC and correlated the outcome with the surgical strategy. METHODS Records of 402 patients who underwent liver resection(More)
Chlamydia pneumoniae causes pneumonia and other respiratory infections in children, adolescents and adults. We tried to evaluate the diagnostic value of detection of serum antibodies by ELISA for C. pneumoniae infections in Japanese children. Serum IgG, IgA and IgM antibodies to C. pneumoniae were determined by the microimmunofluorescence (MIF) test. Serum(More)
