phytomenadione/hemorrhage

Oral and intramuscular phytomenadione (vitamin K1) prophylaxis became an issue following the report of a potential carcinogenic effect of intramuscular but not oral phytomenadione prophylaxis. There is increasing evidence, however, that oral phytomenadione prophylaxis is less effective for the

Tonsillectomy is a common procedure in otorhinolaryngology and postoperative haemorrhage is a well-known complication. In this case, a 34 year-old male with obstructive sleep apnoea and no coagulation defects was operated; 30 minutes after the operation he presented with primary post operative

BACKGROUND Early infant (1-60 days of life) male circumcision is being trialed in Africa as a human immunodeficiency virus prevention strategy. Postcircumcision bleeding is particularly concerning where most infants are breastfed, and thus these infants are at increased risk of vitamin K deficiency

OBJECTIVE To evaluate the efficacy of oral menadiol compared to intravenous phytomenadione when correcting coagulopathies associated with cholestasis. METHODS A total of 26 patients with cholestasis and an international normalized ratio (prothrombin time) greater than 1.2, were randomized to receive

Painless bleeding in a patient presenting from the community with elevated coagulation studies rarely makes the physicians suspect superwarfarin or rodenticide poisoning. Although a significant number of superwarfarin exposure cases are diagnosed every year, we believe there appears to be delay in

Two patients, a women of 70 and a man of 75 years old, who were using phenprocoumon chronically, and were monitored by a regional thrombosis service, received a macrolide antibiotic, clarithromycin and roxithromycin respectively, for an airway infection. Both patients developed a serious increase in

Based on a case history of fetal haemorrhage due to maternal antiepileptic treatment and a review of 40 previously described similar cases, it is recommended that epileptic mothers receive vitamin K tablets throughout the month before delivery and intravenously during labour. It is further

OBJECTIVE To evaluate oral vitamin K prophylaxis at birth by giving 2 mg phytomenadione, followed by weekly oral vitamin K prophylaxis; 1 mg was administered by the parents until 3 mo of age. METHODS A total of 507850 live babies were born in Denmark during the study period, November 1992 to June

Pregnant women with epilepsy constitute 0.5% of all pregnancies. Proper seizure control is the primary goal in treating women with epilepsy. The commonly used anticonvulsants are established human teratogens. Factors such as epilepsy, anticonvulsant-induced teratogenicity, patient's genetic

Recently published American and British guidelines have comprehensively reviewed the indications for long term anticoagulation. The best evidence currently available supports the use of long term oral anticoagulants in patients with nonvalvular atrial fibrillation (NVAF), venous thromboembolic

A major complication of cholestasis is fat malabsorption related to decreased intestinal bile acids, which leads to malnutrition and fat-soluble vitamin deficiency. The impaired excretion of bile acids leads to a low intraluminal micellar concentration that causes long-chain triglyceride lipolysis

OBJECTIVE The ability of oral vitamin K to eliminate all risk of vitamin K deficiency bleeding during the first three months of life was studied. METHODS Babies (n=182,000) in the north of England judged well enough to be offered milk within 12 hours of birth were given 1 mg of phytomenadione

Vitamin K is a fat-soluble vitamin crucial to the production of many proteins involved with the coagulation process. It is integral in the synthesis of coagulants (factors II, VII, IX and X) and anticoagulants (proteins C and S). It is generally recognised that routine administration of vitamin K

Anticoagulation with antivitamin K (AVK) is very effective for primary and secondary prevention of thromboembolic events. However, questions persist about the risks and management of over-anticoagulation. For reversal of excessive anticoagulation by warfarin, AVK withdrawal, oral or parenteral

Anticoagulant pesticides are used widely in agricultural and urban rodent control. The emergence of warfarin-resistant strains of rats led to the introduction of a new group of anticoagulant rodenticides variously referred to as 'superwarfarins', 'single dose' or 'long-acting'. This group includes
