OBJECTIVE To determine whether the use of mixed micellar vitamin K improves the efficacy of the 3 x 2 mg oral vitamin K prophylaxis schedule. DESIGN Nationwide active surveillance for vitamin K deficiency bleeding (VKDB) complemented with two surveys on the use of the mixed micellar preparation in hospitals and by paediatricians. SETTING AND PATIENTS Infants in Germany in 1997-2000. INTER...

Vitamin Kdeficiency bleeding (VKDB) previously known as hemorrhagic disease of the newborn has been classified as Early (0-24hrs), Classic (2-7 days) and Late (1-6 months). Child birth following the maternal ingestion of anti-epileptic drugs such as Phenytoin, is liable to result in early VKDB as well as bone changes in the fetus. Other maternal risk factors for VKDB include medications such as...

BACKGROUND In many developing countries vitamin K prophylaxis is not routinely administered at birth. There are insufficient data to assess the cost effectiveness of its implementation in such countries. OBJECTIVE To estimate the burden of intracranial haemorrhage caused by late onset vitamin K deficiency bleeding in Hanoi, Vietnam. METHODS Cases of intracranial haemorrhage in infants aged ...

Vitamin K deficiency is associated with malnutrition in some complications, such as hyperemesis gravidarum, active gastrointestinal diseases, and psychological disorders. Maternal vitamin K deficiency can cause fetal bleeding, in particular, fetal intracranial hemorrhage. Although fetal hemorrhage is uncommon, severe damage to the fetus may be inevitable. We describe a pregnant woman with vitam...

The development of vitamin K deficiency, vitamin K requirement and warfarin susceptibility were studied in several types of warfarin-resistant .and non-resistant rat. Domesticated HW strain rats needed about 13 times as much vitamin Kl as did Wistar rats to maintain normal blood-clotting function, while HS strain rats were intermediate in this and in their susceptibility to warfarin. The vitami...

Cystic fibrosis (CF) patients are at high risk for vitamin K deficiency. The effects of vitamin K supplementation are very ambiguous. Therefore, we aimed to define the determinants of vitamin K deficiency in a large cohort of supplemented - 146 (86.9%) and non-supplemented - 22 (13.1%) CF patients. Vitamin K status was assessed using prothrombin inducted by vitamin K absence (PIVKA-II) and unde...

Prevention of early vitamin K deficiency bleeding (VKDB) of the newborn, with onset at birth to 2 weeks of age (formerly known as classic hemorrhagic disease of the newborn), by oral or parenteral administration of vitamin K is accepted practice. In contrast, late VKDB, with onset from 2 to 12 weeks of age, is most effectively prevented by parenteral administration of vitamin K. Earlier concern...

Factor VII (FVII) is found in small amounts in plasma and has a very short half-life in circulation. FVII is vitamin K-dependently synthesized in the liver. As such, hepatopathies, vitamin K deficiency, or use of vitamin K antagonists is the cause of acquired deficiency. Other types of acquired FVII deficiencies are rare.1 Here we describe a case of acquired factor VII deficiency associated to ...

Patients with coumarin induced skin necrosis presents with painful purpura and erythematous bluish swelling of the skin complicated by blister formation, hemorrhage and immanent gangrene. Coumarin induced hemorrhagic skin necrosis occurs within one week after initiation of coumarin treatment at time of prolonged INR caused by an imbalance within the vitamin K dependent anticoagulant and procoag...
