OBJECTIVES We attempted to determine the clinical usefulness of a preoperative platelet count for predicting malignancy in patients presenting with a pelvic mass. Additionally, in patients in whom a preoperative serum CA 125 level was also determined, the clinical usefulness was compared. STUDY DESIGN A retrospective review of charts of 241 patients(More)
Blood pressure (BP) and heart rate (HR) are influenced by the sleep-wake cycle, with relatively abrupt falls occurring in association with sleep onset (SO). However, the pattern and rate of fall in BP and HR during SO and the processes that contribute to the fall in these variables have not been fully identified. Continuous BP and HR recordings were(More)
Eleven children with acute lymphoblastic leukemia and chronic liver disease, who had negative reactions for hepatitis B virus markers in the liver, were studied at the time of therapy withdrawal for an antigen-antibody system linked to non-A, non-B (NANB) hepatitis infection. By immunofluorescence, six of the 11 children had a positive reaction for the NANB(More)
From 1992 to 1994, 37 fractures (36 patients) were treated with hybrid external fixation for tibial plafond or distal tibial fractures. The fractures were classified according to the AO classification: A1 (3), A2 (3), A3 (4), C1 (6), C2 (12), C3 (9). There were 11 open injuries, and in 27 patients (75%) the mechanism of injury was high energy trauma.(More)
Sequential chemotherapy may improve treatment efficacy avoiding the additive toxicity associated with concomitant polichemotherapy in hormone-refractory prostate cancer (HRPC). Forty patients received docetaxel 30 mg m(-2) intravenous (i.v.), weekly, plus estramustine 280 mg twice daily for 12 weeks. After 2 weeks rest, patients with a decline or stable PSA(More)
Nucleolar Organizer Regions (NORs) code for ribosomal RNA and are thought to be an accurate representation of the percentage of cells in S-phase. NORs are associated with nonhistone nucleoproteins, which can be stained with silver (AgNORs). An increased number of AgNORs has been observed in many malignancies. AgNORs were counted in three groups of patients(More)
Angiotensin converting enzyme (ACE) catalyzes the conversion of angiotensin I to angiotensin II (1) and plays a fundamental role in bradykinin degradation (2). It is localized in vascular endothelial cells (3), predominantly in the capillaries of the lung (4). It has been supposed that the variation of the levels of ACE might provide a marker of endothelial(More)
An antigen-antibody system has been identified by immunofluorescence in patients with non-A, non-B hepatitis. The non-A, non-B antigen was localized in the hepatocyte nuclei of liver biopsies from patients with acute post-transfusion or sporadic non-A, non-B hepatitis and in those from patients with chronic post-transfusion non-A, non-B hepatitis, the(More)
