Primary peritoneal cystadenocarcinoma is a rare tumor of similar histogenic origin as primary ovarian carcinoma. We present a case of primary peritoneal serous cystadenocarcinoma mimicking advanced colorectal cancer in a 68 yr-old African American female. Radiology, endoscopy and cytology yielded only inconclusive findings. Immunohistochemical analysis of percutaneously obtained ascitic fluid p...

Long-term peritoneal dialysis (PD) frequently produces morphological and functional changes of the peritoneum, which makes continuation of PD difficult. Moreover, the progression of peritoneal injury causes complications and poor prognosis. Since therapeutic treatments for peritoneal injury during PD have yet to be established, it is important to diagnose peritoneal injury as early as possible....

To investigate the effects of peritoneal fluid from patients with endometriosis on mouse peritoneal macrophages (Mphi), peritoneal fluid from endometriosis patients (n = 15) were added to a monolayer of C3H/HeJ mouse peritoneal Mphi. Tumor necrosis factor-producing activity was measured by the L929 assay activated with FK-23 (a preparation of heat-killed Enterococcus faecalis). Tumor necrosis f...

BACKGROUND Controversy exists as to whether electric charges of plasma proteins influence their transport across the peritoneal membrane during CAPD. Fixed negative charges in the peritoneal membrane are diminished during peritonitis in rats. METHODS Peritoneal clearances of 10 proteins and their isoforms were used to establish the relationship between peritoneal clearance and molecular weigh...

A 14 years old boy who had a ventriculo-peritoneal shunt since the age of 5 months, was hospitalized due to headaches, nausea, vomiting and abdominal distension. In abdominal CT and sonographic evaluation, pancreatic pseudocyst or mesentric cyst were suspected. Evaluation of the shunt by radionuclide, however, was diagnostic and revealed a pseudocyst at the peritoneal end of the shunt. Th...

The prediction of peritoneal recurrence in colorectal cancer patients is required for improvement of prognosis. In this study, we focused on establishing a novel rapid RNA direct amplification system with transcription-reverse transcription concerted reaction (TRC) to detect carcinoembryonic antigen (CEA) mRNA in peritoneal washings, and its usefulness as a prophylactic tool for peritoneal recu...
