Hemophilia A is a X-linked hereditary condition that lead to decreased factor VIII activity, occurs mainly in males. Decreased factor VIII activity leads to increased risk of bleeding events. During neonatal period, diagnosis is made after post-partum bleeding complication or unexpected bleeding after medical procedures. Subgaleal hemorrhage during neonatal period is a rare, severe extracranial...

BACKGROUND AND OBJECTIVES on Willebrand's disease (VWD) is the most common hereditary bleeding disorder. Its severity can be classified on the basis of von Willebrand factor (VWF) and factor VIII (FVIII) plasma levels and according to the clinical relevance of bleeding episodes. However, patients with very low VWF activity may exhibit a mild bleeding tendency. The basis for this heterogeneous c...

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...

Gaucher disease is a rare, hereditary disease caused by lack of a lysosomal enzyme. This results in the accumulation of glucocerebroside in the cells of the reticuloendothelial system, including the bone marrow. The orthopaedic manifestations of this disease are important for the orthopaedic surgeon to recognize and understand. Patients with Gaucher disease are at risk for pathologic fracture, ...

Familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by episodic fever and inflammatory polyserositis, which could lead to a variety of manifestations, including recurrent abdominal pain. Herein, a 12-year-old boy who has suffered from fever and bloody diarrhea since early childhood is described. All structural and underlying disorders leading to bleeding we...

Von Willebrand disease, the most common hereditary bleeding disorder, arises from quantitative or qualitative defect of von Willebrand factor (VWF). The aim of the treatment is to correct the dual defect of hemostasis caused by the abnormal/reduced VWF and the concomitant deficiency of factor VIII (FVIII). The synthetic vasopressin analogue desmopressin is the mainstay of therapy in about 80% o...
