Natural changes in peritoneal equilibration test results in continuous ambulatory peritoneal dialysis patients: a retrospective, seven year cohort survey

We conducted a retrospective, 7 year cohort survey to examine the natural changes in peritoneal equilibration test (PET) results in patients with long-term uneventful continuous ambulatory peritoneal dialysis (CAPD). Thirty-two (17 males, 15 females) patients on CAPD with two or more standard PETs performed more than 6 months apart, in the absence of peritoneal insult, were included. Changes and pattern of PET results were evaluated by the dialysate to plasma ratio of creatinine (D:P-cre), the fourth h dialysate to instilled glucose ratio (D4:Do) and ultrafiltration volume (UF, ml). The subgroups included high (H), high-average (HA), low-average (LA), or low (L) transporters with the dividing ratios (D:P-cre) of >0.81, >0. 65 to 0.81, >0.5 to 0.65, and <0.5, respectively. The median D:P-cre significantly decreased (p = 0.04), but neither the D4:Do nor the final median UF significantly decreased. The change in D:P-cre was strongly and inversely correlated with the initial D:P-cre value (r = -0.68; p < 0.05). A similar relationship was found between the change in the final D4:Do and the initial D4:Do (r = -0.752; p < 0. 01) and between the change in the final UF and the initial UF (r = -0.875; p < 0.01). No correlation was found between the change in D:P-cre and the age of the patient, the time interval between PETs, monthly dialysate glucose exposure, or underlying diabetes/non-diabetes. The final peritoneal transport pattern was altered with 5 (15.6%) patients remaining in the extreme subgroups (H or L) and, by contrast, 84.4% (27/32) of the patients now in the averaged (HA or LA) groups (p < 0.01, chi2 test). We demonstrated a natural "centralization" migration of PET results after long-term uneventful CAPD, which may help to explain why patients with extreme PET characteristics, that is, H or L, continued to do well on CAPD.     

Yellow nail syndrome in infancy

Abstract: This report describes an infant with clinical features consistent with the yellow nail syndrome (YNS), a rare autosomal dominant disorder. He presented at birth with congenital lymphoedema and was referred at 6 months of age for investigation of recurrent cough and wheeze. He had clinical and radiological evidence of bilateral pleural effusions and a pericardial effusion. Following a lung biopsy and pericardial window these were shown to be manifestations of his lymphatic abnormality. He also had persisting middle ear effusions causing conductive deafness requiring hearing aids and secondary immunodeficiency requiring regular immunoglobulin infusions.     

Features of the renin-angiotensin system in ascites and pleural effusion during severe ovarian hyperstimulation syndrome

Purpose: The purpose of this work was to investigate the ovarian renin-angiotensin system (RAS) during severe ovarian hyperstimulation syndrome (OHSS) with ascites and pleural effusion. Methods: Two patients who developed severe OHSS after ovarian stimulation for in vitro fertilization were investigated. Both patients presented ascites and pleural effusion. Blood, ascites, and pleural fluid were simultaneously sampled during therapeutic paracentesis and thoracocentesis. Renin activity, active renin, prorenin, and angiotensin II immunoreactivity (Ang II-ir) were measured simultaneously in plasma, ascites, and pleural fluid. Results: Prorenin, renin activity, active renin, and Ang II-ir levels were much higher than normal plasmatic laboratory norms in the three compartments. Prorenin and Ang II-ir levels were the highest in the ascites, while they were in the same range in the pleural fluid and in the plasma. Conclusions: The present findings provide additional evidence for the ovarian origin of the prorenin and Ang II-ir in the ascites of severe OHSS.     

Effect of peritoneal fluid from patients with mild and severe endometriosis on endometrial stromal cell proliferation

The aim of this study was to evaluate and compare the mitogenic effect of peritoneal fluid (PF) from women with mild and severe endometriosis on the endometrial stromal cell proliferation. Increasing concentrations of PF from women with and without mild or severe endometriosis were added to primary endometrial stromal cell cultures and³H-thymidine incorporation was used to assess DNA synthesis in these cultures. PF from women with mild endometriosis induced a statistically significant dose-dependent increase in stromal cell thymidine uptake ranged from 5.8 to 14.5 fold, whereas PF from women with severe endometriosis produced an average 51% inhibition of stromal cell proliferation of compared with cells exposed to non-endometriosis PF or exposed to nutrient medium supplemented with 2.5% calf serum alone. PF samples from patients with stage I endometriosis induced a statistically dose-dependent increase in stromal cell proliferation, whereas PF from patients with stage IV endometriosis caused a significant inhibition.     

Infantile hemangioendothelioma of the thymus with massive pleural effusion and Kasabach-Merritt syndrome: Histopathological, flow cytometrical analysis of the tumor

Infantile hemangioendothelioma of the thymus is a rare disease. We describe a patient who developed a large anterior mediastinal mass, severe thrombocytopenia and massive pleural effusion at 1 month of age. Glucocorticosteroid and irradiation therapy had no effect on either the tumor size or clinical symptoms and the tumor was resected subtotally. Three months after the subtotal resection, the remaining tumor had almost disappeared and the symptoms had resolved. The patient has now been well for 1 year after surgery without evidence of recurrence. The tumor tissue was characterized by prominent vascular endothelial proliferation intermixed with a normal thymic structure, producing a picture consistent with that of an infantile hemangioendothelioma in the thymus, lmmunohistochemically, the tumor cells showed positive staining for vimentin, factor VIII and CD34. The DNA stemline and proliferative activity were examined by flow cytometry, which revealed a diploid stemline with a low growth fraction. DNA content and cell cycle analyses of the tumor tissue may be useful for predicting the biological behavior of the tumor.     

Mastoid size and otitis media with effusion: Question of correlation

Objectives/Hypothesis: To determine the incidence of otitis media (OME) with effusion on histologic examination in temporal bones with mastoid cavities reduced by the fenestration procedure for otosclerosis. Study Design: Temporal bone histologic study. Methods: Light-microscopic examination of serially sectioned temporal bones. Results: The incidence of otitis media with effusion in temporal bones with prior fenestration operation was not any more frequent than the control group of temporal bones with surgically unaltered mastoid cavity. Conclusions: There is no increased incidence of otitis media with effusion in temporal bones with prior fenestration operation.     

Complex hyperplastic endometrium in a peritoneal leiomyoma following a CISH hysterectomy

We describe a case of a patient presenting with an abdominal tumor 4 years after a classical intrafascial serrated-edged macro-morcellated hysterectomy. The tumor was removed surgically and proved microscopically to be a peritoneal leiomyoma containing complex hyperplastic endometria. To our knowledge, this has never been described before. In addition, the pathogenesis of this rare disease is discussed.     

Malignant pericardial effusion with cardiac tamponade in a patient with metastatic vaginal adenocarcinoma

Malignant pericardial effusion with cardiac tamponade is a rare manifestation of metastatic gynecological cancer. A 35-year-old female was diagnosed with clear cell adenocarcinoma of the vagina. Four years after partial vaginectomy, she developed regional recurrence and was treated with surgical excision followed by platinum-based chemotherapy and radiation therapy. Six years later, the patient was diagnosed with lung metastases and received a combination adriamycin and platinum-based chemotherapy. Shortly after completing treatment, she presented with weakness and was found to be hypotensive on physical exam. Computed tomography scan confirmed a pericardial effusion with evidence of bilateral heart failure. She underwent an emergent pericardiocentesis and eventual pericardial window procedure. Metastatic adenocarcinoma of the vagina can present with malignant pericardial effusion with cardiac tamponade. Therefore, gynecologists and gynecological oncologists need to be familiar with the diagnosis and management of this disease process.
