Biliary strictures may be due to a variety of benign and malignant processes. Imaging with endoscopic ultrasonography (EUS) often suggests the diagnosis, but is usually not definitive. EUS-guided fine needle aspiration (FNA) facilitates the diagnosis of extrahepatic biliary strictures, although peritioneal metastases due to needle tract seeding may occur after EUS-FNA of cholangiocarcinoma. In addition to diagnosis of strictures, EUS may play an important role in staging of cholangiocarcinoma.

We report an unusual case of a 78-year-old Caucasian female, who presented with peritoneal carcinomatosis and hypercalcemia, and was found to have a rapidly progressive primary squamous cell carcinoma of the urinary bladder. Squamous cell bladder carcinoma is a rare malignancy in the United States, accounting for just 1-3% of bladder tumors. Interestingly our patient lacked the established risk factors, including exposure to the parasite Schistosoma haematobium, recurrent urinary tract infections, bladder calculi, radiation exposure, chronic indwelling catheter, neurogenic bladder, or tobacco abuse...

Carcinoma of the parathyroid gland is infrequent in patients with secondary hyperparathyroidism. Typical clinical symptoms are related to the presence of a neck mass and hypercalcemia. We describe a case of a 55-year-old man in whom primary parathyroid carcinoma led most likely to the development of end-stage dialysis-dependent renal failure, and the diagnosis of the cancer was delayed due to ectopic localization of the tumor, and dramatic complications in the clinical course of the disease, including acute pancreatitis and peritionitis...

PURPOSE OF REVIEW: Portal hypertension is responsible for most of the complications associated with cirrhosis, specifically variceal hemorrhage, ascites and hepatic encephalopathy. Progress in understanding the pathophysiology of portal hypertension and improvements in the diagnosis and management of its complications that have occurred over the last year are discussed. RECENT FINDINGS: Endothelial dysfunction contributes to the pathogenesis of portal hypertension and may represent a novel therapeutic target...

Patients receiving dialysis therapy are known to be at increased risk of tuberculosis (TB). The aim of this study was to evaluate the frequency, clinical characteristics and course of TB disease in dialysis patients treated at our institution. Medical records of 330 regular haemodialysis (n=219) and continuous ambulatory peritoneal dialysis (n=111) patients (172 male, 158 female; mean age 55+/-16 y) who were cared for at our tertiary university hospital between December 2002 and January 2006 were retrospectively evaluated...

In present study, bank voles Clethrionomys glareolus were peritioneally injected with different doses of cadmium, 0, 1.5, 3.0 mg Cd/kg body mass. Animals were sacrificed on the 21st day after cadmium exposure and the liver and kidney were obtained for cadmium, zinc and iron analysis using atomic absorption spectrometry. Results showed that cadmium had accumulated in the tissues according to dosage and sex. Cadmium affected the survival and body masses of dosed females. Cadmium decreased the iron concentrations in the liver of voles, whereas zinc concentrations increased in both the kidney and liver...

BACKGROUND: Identification of extracellular matrix proteins (ECM) associated with tumor cell metastasis may generate targets for future therapy against pancreatic cancer metastases. We hypothesized that comparison of ECM-associated gene expression in primary and metastatic pancreatic tumors would identify ECM proteins associated with pancreatic metastasis. STUDY DESIGN: A clinically relevant model of pancreatic cancer was used to generate RNA from primary and metastatic tumors; it was evaluated by microarray analysis with subsequent cluster analysis...

Successful peritoneal dialysis is based on a patent access, the instillation into the peritoneal cavity of a dialysate prescription solution, and an intact, functioning peritoneal membrane with adequate blood flow. This article describes the basic concepts of peritioneal dialysis.

The effects of volatile oil from Rheum palmatum (RVO) on immunologic function in mice are studied. The results show that the delayed type hypersensitivity (DTH) induced by 2, 4-dinitrochlorobenzene, lymphocytes transformation of (3H)-TdR induced by PHA, clearance rate of ivcarbon particles, phagocytic function of peritioneal macrophage and production of hemolysin induced by SRBC are markeyly increased with RVO given by oral administration or inhalation.

Two children initially referred for evaluation of ascites were diagnosed as suffering from celiac disease. Positive physical signs of ascites were present in the absence of free fluid in the peritioneal cavity. Physical findings of ascites were caused solely by dilated small intestinal loops filled with copious fluid. "Pseudoascites" should be recognized as a physical sign and possible mode of presentation of celiac disease.

Interferon is produced in cultures of rabbit leukocytes in response to infection with Newcastle disease virus or in the absence of known viral infection. The macrophage appears to be the responsible producing cell. Cultures prepared from sterile peritoneal exudates, which contained about 90% macrophages, are at least as efficient as cultures of rabbit kidney (RK) cells in their capacity to synthesize NDV-induced interferon. Interferon can be detected in the medium by 2 hr after viral infection and the titers usually reach a peak of 10,000 PDD(50)/ml by 4-6 hr...

Pneumatosis intestinalis (PI) is a well-recognized manifestation of necrotizing enterocolitis (NEC) in the newborn--a condition that often requires surgical intervention for infarcted bowel. However, little information is available concerning PI in older children or its management. Sixteen older infants and children (greater than 2 months) had x-ray findings of PI (intramural air). There were eight girls and eight boys ranging in age from 2 months to 8 years. Associated conditions included short bowel syndrome (SBS) (8), congenital heart disease (2), iron ingestion (1), nesidioblastosis (1), hemolytic anemia (1), rheumatoid arthritis (1), bronchopulmonary dysplasia (BPD) (1), and malrotation (1)...

Aneurysms of the hepatic artery are rare and, when symptomatic, they may present a triad of upper abdominal pain, gastrointestinal bleeding, and obstructive jaundice. Asymptomatic and unsuspected aneurysms are demonstrated occasionally by abdominal arteriography or are encountered infrequently during abdominal operation for an unrelated disease. Hepatic artery aneurysms have great potential for rupture with bleeding into the peritioneal cavity, the common bile duct, or an adjacent hollow viscus. Morbidity and mortality with a ruptured aneurysm are high, and aggressive and imaginative operative therapy is required...

We have developed a model of experimental haemorrhagic pancreatitis in pigs with a 100% mortality within 24 h without treatment. In this model we have studied the production of peritioneal exudate and compared the concentrations of amylase, lipase and phospholipase A2 in the ascitic exudate and serum. The results suggest that the determination of phospholipase A2 might be important in the diagnosis and follow-up of acute pancreatitis.

Somatic cell hybrids between mouse peritioneal macrophages and HT-1080 human fibrosarcoma cells lose mouse chromosomes and retain the entire complement of human chromosomes. In contrast, somatic cell hybrids between cells derived from two different mouse continuous cell lines and HT-1080 human cells were found to lose human chromosomes preferentially. Loss of mouse chromosomes is not a general property of hybrids between mouse macrophages and transformed human cells; the hybridization of mouse macrophages with cells derived from five different human fibroblast lines transformed by simian virus 40 resulted in the production of hybrid clones that preferentially lost human chromosomes...

To investigate the antigenic relationship between the macrophage and lymphocyte Fc receptors (FcR), a monoclonal antibody capable of blocking mouse macrophage Fc receptors was selected. Hybrids were formed by fusing the P3U1 mouse myeloma and spleen cells from a rat immunized with the mouse macrophage-like cell lines J774 and P388D1. The Fab fragment of the monoclonal IgG secreted by clone 2.4G2, inhibited the trypsin-resistant Fc receptor II (FcRII), which is specific for immune aggregates of mouse IgG1 and IgG2b, but had no inhibitory effect on the trypsin-sensitive Fc receptor I (FcRI), which binds monomeric IgG2a and erythrocytes coated with IgG2a...
