The role of vascular endothelial growth factor leading to vascular leakage in children with dengue virus infection.

Unlabelled: Increased vascular permeability is the main aetiology for hypovolaemic shock and circulatory failure in dengue haemorrhagic fever (DHF).

Aim: To investigate the role of vascular endothelial growth factor (VEGF) in the pathogenesis of DHF.

Methods: Serum samples from 41 patients [15 dengue fever (DF), 26 DHF] with serologically confirmed dengue virus infection during the febrile, toxic, convalescent stages and at follow-up were analysed for VEGF.

Selection of coil for transcatheter closure of small patent ductus arteriosus.

The authors reported the results in transcatheter coil occlusion of patent ductus arteriosus (PDA) less than 4 mm, based on a policy in selection of the appropriate type and number of coils for size of PDA. The authors used one 0.035 inch detachable coil, 5 mm in diameter, in PDA less than or equal to 2 mm, and two 0.
