Platelet storage pool deficiency is a family of clotting disorders characterized by deficient granules in platelets. Individuals with these disorders have too few or abnormally functioning alpha granules , delta granules , or both alpha and delta granules and are therefore unable to form effective clots, which leads to prolonged bleeding.
Factor X deficiency (X as Roman numeral ten) is a bleeding disorder characterized by a lack in the production of factor X (FX), an enzyme protein that causes blood to clot in the coagulation cascade. Produced in the liver FX when activated cleaves prothrombin to generate thrombin in the intrinsic pathway of coagulation.
[2] [3] [4] Acquired dysfibrinogenemia is a non-hereditary disorder in which fibrinogen is dysfunctional due to the presence of liver disease, autoimmune disease, a plasma cell dyscrasias, or certain cancers. It is associated primarily with pathological bleeding. [5]
Bipolar disorder is a long-term mood disorder characterized by major fluctuations in mood — both high and low — that can impact daily functioning and behavior. Bipolar Disorder: 4 Types & What ...
ICD-10 coding number Diseases Database coding number Medical Subject Headings Iron-deficiency anemia: D50: 6947: Iron-deficiency anemia (or iron deficiency anaemia) is a common anemia that occurs when iron loss (often from intestinal bleeding or menses) occurs, and/or the dietary intake or absorption of iron is insufficient. In such a state ...
The following revised diagnostic criteria for essential thrombocythemia were proposed in 2005. [13] The diagnosis requires the presence of both A criteria together with B3 to B6, or of criterion A1 together with B1 to B6. [14] The criteria are as follows: [14] A1. Platelet count > 400 × 10 3 /μL for at least 2 months. A2. Acquired V617F JAK2 ...
Light transmission aggregometry is widely accepted as the gold standard diagnostic tool for assessing platelet function, and a result of absent aggregation with any agonist except ristocetin is highly specific for Glanzmann's thrombasthenia. [9] Following is a table comparing its result with other platelet aggregation disorders:
Bleeding time may be affected by platelet function, certain vascular disorders and von Willebrand Disease—not by other coagulation factors such as haemophilia. Diseases that may cause prolonged bleeding time include thrombocytopenia, disseminated intravascular coagulation (DIC), Bernard-Soulier disease, and Glanzmann's thrombasthenia. [9]
