Review Comparative StudyCongenital cardiovascular malformations in Chinese children with Down's syndrome.
149 Chinese children (70 boys, 79 girls) with Down's syndrome and congenital heart disease were studied. Diagnosis of the cardiac abnormality was made by cardiac catheterisation in 119, two-dimensional echocardiography in 23 and autopsy in 7. The commonest lesion was ventricular septal defect which was present in 43.6%, a higher frequency than that reported in Caucasians. ⋯ Other cyanotic congenital heart conditions were very rare and coarctation of aorta was not seen. An aberrant right subclavian artery arising from the descending aorta was present in 16.5% and abnormalities of the radial artery at the wrist were found in 19%. The literature on patterns of congenital heart diseases seen in Down's syndrome was reviewed.

Comparative StudyA growth velocity standard for Chinese children in Hong Kong.
Racial differences in the size of children make it questionable that a widely used Caucasian velocity reference standard can be used for Chinese children. In the present study, the growth velocity in 935 healthy Chinese children aged 4-6 was examined, showing that height velocity was significantly lower than Tanner's references. With the Caucasian velocity standard, Chinese children might be misinterpreted as growing abnormally slowly. In order to detect growth and endocrine disorders of childhood and adolescence, a Chinese growth velocity standard for children of 0 to 18 years must be established.

The duration of viremia in patients with epidemic hemorrhagic fever (EHF) was studied using immunofluorescence technique and cell culture assays. The duration of virus in plasma of EHF patients was about 1 week, which was concomitant with the febrile phase of the disease. ⋯ High titre EHF antibody of IgG, TgM was unable to neutralize the virus in human blood. The results revealed that a blood-cell-associated prolonged viremia is one of the characteristics of EHF infection.
