OBJECTIVES To describe the presentation, clinical course, therapeutic response, and long-term follow-up of patients with a syndrome of periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). STUDY DESIGN Patients with PFAPA (n = 94) referred over a 10-year period completed a registry form and provided medical records. Follow-up(More)
OBJECTIVE Evaluate experience over 15 years with treatment of this lesion. SUMMARY BACKGROUND DATA Biliary cystadenoma, a benign hepatic tumor arising from Von Meyenberg complexes, usually present as septated intrahepatic cystic lesions. METHODS Data were collected concurrently and retrospectively on patients identified from hospital medical records(More)
Samples of toxic scallop (Patinopecten yessoensis) and clam (Saxidomus purpuratus) collected on the northern coast of China from 2008 to 2009 were analysed. High-performance liquid chromatography with post-column oxidation and fluorescence detection was used to determine the profile of the main paralytic shellfish poisoning (PSP) toxins in these samples and(More)
A thin-layer chromatography (TLC) method has been developed for the semi-quantitative analysis of domoic acid (DA) in shellfish tissues. Tissues were extracted in a single-step homogenization of tissue with 50 % aqueous methanol and then taken through a selective strong anion exchange cleanup. Cleaned extracts were applied directly to silica gel TLC plates(More)
BACKGROUND Biliary complications occur following approximately 25% of liver transplantations. Efforts to decrease biliary complications include methods designed to diminish tissue ischemia. Previously, we reported excellent short-term results and decreased biliary anastomosis time in a porcine liver transplant model using non-penetrating, tissue everting(More)
Radiofrequency ablation (RFA) is well described in the treatment of primary hepatic malignancies and colorectal carcinoma hepatic metastases. A known complication of RFA is the development of hepatic abscess. The management of hepatic abscesses subsequent to RFA for metastatic disease is not well described. A 49-year-old female with pancreatic(More)
