Hemostasis is a finely balanced process in which an insult to a blood vessel wall, either by injury or surgical intervention, stimulates a pair of parallel, yet associated, pathways that lead to the termination of blood loss. The coagulation cascade is initiated by the interaction between exposed subendothelial tissue factor and circulating blood and includes a series of amplification steps tha...

Fifty children with suspected non-accidental injury, most of whom had bruising, were investigated to exclude a bleeding disorder. The following investigations were undertaken in each child: full blood count; platelet count, size, and shape; prothrombin time; partial thromboplastin time including mix with normal plasma; fibrinogen; and a bleeding time. The results of these initial investigations...

Patients with bleeding disorders or who are anticoagulated may present with haematuria. Failure to investigate such patients when they first present may delay the diagnosis and treatment of a serious genito-urinary pathology.

Case I A previously well, 27-year-old woman was admitted to an acute haematology unit with multiple severe bruising. For 3 months before admission she had been having vague colicky abdominal pain with pale, bulky, offensive stools which were difficult to flush away. She had lost 9 5 kg in weight. Two weeks before admission she had developed spontaneous bruising of her limbs. She had no melaena ...

Invasive procedures for patients with bleeding disorders require planning on the part of the health care team. The patient population affected involves those with hereditary bleeding disorders, such as von Willebrand disease or hemophilia; in addition, patients who use antithrombotic drugs must be considered and their care managed. The choice of treatment depends on a number of factors, includi...

INTRODUCTION Male circumcision practice is an invasive procedure that is using worldwide. It makes challenges to haemostatic system and its possible haemorrhagic side effects are more serious in bleeding individuals than normal subjects. In most cases, it can be complete controlled using infusion of appropriate amount of coagulation factors before and post circumcision. AIM We aim to document...

In women, von Willebrand disease (VWD) is the most common inherited bleeding disorder. Since VWD and other inherited bleeding disorders are autosomal disorders, they affect women and men. Menorrhagia, or heavy menstrual bleeding (HMB), is the most common symptom of women with bleeding disorder experience. Objectively, it is defined as bleeding that lasts for more than seven days or results in t...

Hemostasis is initiated by injury to the vascular wall, leading to the deposition of platelets adhering to components of the subendothelium. Platelet adhesion requires the presence of von Willebrand factor and platelet receptors (IIb/IIIa and Ib/IX). Additional platelets are recruited to the site of injury by release of platelet granular contents, including ADP. The "platelet plug" is stabilize...
