The general practitioner (GP) fundholding scheme was introduced as part of the Conservative governments 1991 National Health Service reforms and abolished by the Labour government in 1998. This paper contends that the scheme was introduced and abolished without policy-makers having any valid evidence of its effects. In particular, it focuses on the salient features of the decision to abolish. T...
Glanzmann thrombasthenia is an inherited bleeding disorder due to a functional reduction or absence of platelet GPIIb/IIIa (alphaIIbbeta3) integrin receptors. Based on a prolonged bleeding time and absence of platelet aggregation in response to physiologic agonists, a 55-year-old white man was diagnosed as having Glanzmann thrombasthenia. The patient's platelet fibrinogen level was approximatel...
Background: The most common polymorphisms identified in the Methylenetetrahydrofolate reductase (MTHFR) gene, C677T and A1298C lead to defective activity of this enzyme and increase the risk of venous and arterial thrombosis. There are limited investigations regarding the effects of thrombogenic polymorphisms on the clinical phenotypes of rare hereditary hemorrhagic disorders like Glanzmann's t...
The molecular nature of platelet receptors for quinineand quinidine-dependent antiplatelet antibodies (Q.Ab and Qd.Ab) was studied by immunoblotting. One Q.Ab caused quinine-dependent lgG binding to platelet proteins with molecular weights (mol wts) of 1 74 Kd and 93 Kd and another to only a 93-Kd protein. A third Q.Ab caused binding to 1 74-. 140-. 93-. and 57-Kd proteins, while a fourth Q.Ab ...
Platelets play a critical role in hemostasis and are involved in wound repair and inflammatory processes. Contact to the subendothelial matrix induces platelet activation that is followed by release of cytokines and growth factors and formation of a vascular plug. Several inherited defects of platelet function resulting in bleeding diathesis are known. However, only in the minority of these dis...
