At least 22 members of a large kindred have a bleeding tendency resulting from an autosomal dominant disorder of platelet production and function. Phenotypic manifestations include mild to moderate thrombocytopenia, bleeding time prolongation, and abnormal platelet aggregation. Platelet survival time is normal. The platelet disorder in this family appears to differ from known hereditary thrombo...
Frozen shoulder is a glenohumeral joint disorder that perturbs movement because of adhesion and the existence of fibrosis in the shoulder capsule. Platelet-rich plasma can produce collagen and growth factors, which increases stem cells and consequently enhances the healing. To date, there is no evidence regarding the effectiveness of platelet-rich plasma in frozen shoulder. A 45-year-old man ...
Excessive bleeding at surgery is a feared complication in patients with inherited platelet disorders. However, very few studies have evaluated the frequency of surgical bleeding in these hemorrhagic disorders. We performed a worldwide, multicentric, retrospective study to assess the bleeding complications of surgery, the preventive and therapeutic approaches adopted, and their efficacy in patie...
INTRODUCTION Inherited defects in RUNX1 are important causes of platelet function disorders. AIM Our goals were to evaluate RUNX1-related platelet disorders among individuals evaluated for uncharacterized, inherited platelet function disorders and test a proof of concept that bleeding risks could be quantitatively estimated for typical families with an inherited platelet function disorder. ...
Inherited platelet disorders are a heterogeneous group of rare diseases, caused by inherited defects in platelet production and/or function. Their genetic diagnosis would benefit clinical care, prognosis and preventative treatments. Until recently, this diagnosis has usually been performed via Sanger sequencing of a limited number of candidate genes. High-throughput sequencing is revolutionizin...
The search for the components of the platelet surface that mediate platelet adhesion and platelet aggregation began for earnest in the late 1960s when electron microscopy demonstrated the presence of a carbohydrate-rich, negatively charged outer coat that was called the "glycocalyx." Progressively, electrophoretic procedures were developed that identified the major membrane glycoproteins (GP) t...
Decreased platelet inhibition by nitric oxide in two brothers with a history of arterial thrombosis.
Highly reactive oxygen species rapidly inactivate nitric oxide (NO), and endothelial product which inhibits platelet activation. We studied platelet inhibition by NO in two brothers with a cerebral thrombotic disorder. Both children had hyperreactive platelets, as determined by whole blood platelet aggregometry and flow cytometric analysis of the platelet surface expression of P-selectin. Mixin...
The May-Hegglin Anomaly (MHA) is a rare autosomal dominant giant platelet disorder characterized by abnormally large platelets with defective leucocytes and thrombocytopenia varying degrees of bleeding manifestation. Here we report successful pregnancy outcome in primigravida MHA. (Preterm Pre-labour Rupture Membranes) PPROM mother, abnormalities the extremities due to ABS discussed.
