magnesium sulfate is widely used in obstetrics and is drug of choice in two important complications of pregnancy, preeclampsia and preterm labor. the antagonistic effects of magnesium sulfate on calcium ion and on platelet aggregation may lead to changes in bleeding time. this study was conducted to evaluate the effect of magnesium sulfate on bleeding time in women with threatened preterm labor...

This retrospective study investigated the correlations between red blood cell (RBC) count, hemoglobin, and hematocrit on admission, and mortality in 140 patients with subarachnoid hemorrhage (SAH). Correlations between the hematological parameters RBC count, hematocrit, hemoglobin, white blood cell (WBC) count, and platelet count on admission and mortality were investigated. Association of each...

CONTEXT Upper gastrointestinal bleeding associated to esophageal varices is the most dramatic complication of cirrhosis. It is recommended screening every cirrhotic for esophageal varices with endoscopy. OBJECTIVES To evaluate the capacity of the platelet count/spleen diameter ratio in non-invasively predicting esophageal varices in a population of cirrhotics originated in an independent cent...

This study evaluates the platelet count changes in neonates with hyperbillirubinemia who received phototherapy. In this Prospective Descriptive-cross sectional study 144 full term newborns with indirect hyperbillirubinemia who received phototherapy in neonatal ward of Bessat hospital in Hamedan province of Iran were studied from September 2007 to February 2008 for evaluation the effect of photo...

IntroductionPlatelet count estimation is an important element of the diagnostic and treatment process in many disorders. The present study aims to determine the incidence of improper impedance platelet count in severe microcytosis and to state the sensitivity and specificity of various parameters like histogram, red cell distribution width (RDW), mean platelet volume (MPV), platelet flags Metho...

BACKGROUND Thrombocytopenia in cirrhotic patients may be due to deficient production of thrombopoietin. AIMS To determine the relation between thrombopoietin and thrombocytopenia in cirrhotic patients before and after orthotopic liver transplantation. METHODS Thrombopoietin concentrations and platelet counts were measured in 43 cirrhotic patients and 21 normal controls and serially for 14 d...

Background & Aims: Recent studies have shown that thrombocytopenia (TP) is associated with poor outcomes in patients with pneumonia, burns, and H1N1 influenza. The aim of this study is to determine the impact of platelet count trends and TP on mortality in intensive care unit (ICU) patients. Materials & Methods: TP was defined as <150,000 platelets/ml. In this study, 300 patients who had been ...
