Norethynodrel in The Treatment of Factor X Deficiency
Archives of Internal Medicine, 1964The demonstrated improvement of factor X (Prower-Stuart factor) deficiency during pregnancy, 1 and the further demonstration by Alexander and Pechet 2 of increased clotting factors during pregnancy, has prompted the use of norethynodrel, a progestational agent, in the control of this clotting disorder. The case to be reported has been the subject of a

Factor X and its deficiency states
Haemophilia, 1997Summary. Factor X is one of the vitamin‐K‐dependent serine proteases. As a result of its position at the convergence of the intrinsic and extrinsic pathways of the clotting cascade, it plays a crucial role in blood coagulation. Factor X interacts with components of both pathways of coagulation, leading to its activation and the formation of the ...

A NEW VARIANT OF FACTOR X DEFICIENCY (FACTOR X ROMA).
Thrombosis and Haemostasis, 1987A 13 years-old-girl was admitted in our Hospital for a large muscle hematoma of left psoas. At age 3 she had a severe tonsillar bleeding following angina. Afterwards she suffered from easy bruisability and recurrent epistaxis. Prothrombin time (PT) was slightly prolonged (14.7 sec, control 12 sec, INR 1.5), while a more marked prolongation in aPTT was ...

JAMA, 1974
Isolated factor X deficiency in association with abnormal plasma antithrombin activity was recognized in a 59-year-old man with amyloidosis and signs and symptoms of calf pain suggestive of thrombophlebitis. Venographic studies excluded venous thrombosis, and, despite major coagulation abnormalities, there was no hemorrhagic tendency.

Factor X deficiency presenting as a pseudotumor
Journal of Neurosurgery: Pediatrics, 2006The authors report their experience in successfully treating a 15-week-old child who became comatose following a spontaneous intracerebral hemorrhage. It was initially believed that a tumor in the right frontal lobe caused the hemorrhage. Coagulation studies revealed abnormal results on presentation, and the problem was only partially corrected after ...

Systemic Amyloidosis Associated With Factor X Deficiency
Acta Pathologica Japonica, 1984An autopsy case of amyloidosis associated with factor X deficiency is reported. The patient showed a markedly decreased level of factor X (9% normal) and an extremely shortened half‐life of intravenously infused factor X. Amyloid deposition was present in most of the visceral organs with special involvement of the liver and spleen.
