ABSTRACT
This paper evaluated the effect of VKP in the neonates by oral route with different dosages compared to the standard parenteral route giving a single dose at birth. Two hundred and thirty-six healthy, breast-fed infants were divided into 4 groups receiving vitamin K1 1 mg intramuscularly and 2, 3, 5 mg orally during 2-4 hours after birth. The vitamin K dependent clotting factors were measured by the thrombotest at the age of 2 weeks and 4-6 weeks. The result showed no statistical differences among these 4 groups regarding the mean prothrombin complex level and the number of PC deficient subjects. Vitamin K prophylaxis in the newborn babies by 2 mg oral route would be benefit and can be applied routinely as well as 1 mg parenteral route to prevent both HDN and APCD syndrome particularly in breast fed infants. The routine practice of giving vitamin K1 prophylaxis 2 mg orally or 0.5-1 mg intramuscularly should be recommended to all newborn infants. Giving VKP by oral route is practical for developing countries because of simple way of administration, low cost, low toxicity, as well as high efficacy.

Forty children, aged 1/2-14 years, with serologically proven dengue haemorrhagic fever were daily studied for hemostatic tests. There were 4, 20 and 16 cases of grade I, II III respectively. Hemostatic derangements in DHF is a multifactorial mechanism. Vasculopathy, thrombocytopenia, platelet dysfunction were found in most cases. Mild to moderate degree of prothrombin complex deficiency was observed in 15% and 50% of grade II and grade III respectively while laboratory evidence of consumptive coagulopathy was noted in 30% of shock cases and 10% of non-shock cases. Hypofibrinogenemia and increased PTT are commonly seen in grade III reflect the presence of stimulation of intrinsic coagulation pathway probably from immunologic reaction. Frank DIC is very rarely observed. FDP is slightly increased but not as high as in classical DIC. Further study on the role of platelet-endothelial interaction should be elucidated including the efficient management to stop bleeding in severe shock cases.
