Sister chromatid exchange in Chinese newborn infants treated with phototherapy for more than five days.
The frequency of sister chromatid exchange (SCE) was determined in newborn infants given phototherapy for more than five days, then determined again one year later. There were 8 healthy newborn infants and 15 icterus infants; 8 of these were treated with phototherapy for more than 5 days and the other 7 were not. In the follow-up study, 6 treated infants were evaluated. The results revealed that there was an increase in mean SCE frequency of peripheral lymphocytes after phototherapy, which reversed itself one year after treatment discontinuation. Prolonged continuous phototherapy may be responsible for the increase observed in SCEs in Chinese newborn.

FISH analysis in both classical and atypical cases of Williams-Beuren syndrome.
Williams-Beuren syndrome (WBS) is a rare neurodevelopmental disorder, characterized by distinct facial changes, growth deficiency, mental retardation, supravalvular aortic stenosis (SVAS)/peripheral pulmonary stenosis, and associated at times with infantile hypercalcemia. A pilot study has been carried out to assess the reliability of the detection of hemizygosity at the elastin locus by fluorescence in situ hybridization (FISH) analysis as a diagnostic test in both classical and atypical WBS. Eight subjects with classical WBS and four others in whom a diagnosis could not be confirmed on clinical criteria alone were enrolled. In the classical WBS group, five (5/8) had a visible interstitial 7q11.22-11.23 deletion detected by high-resolution banding, and all (8/8) had a submicroscopic deletion of the elastin locus on chromosome 7 by FISH analysis. In the atypical WBS group, only one (1/4) had elastin deletion. The other three, with isolated SVAS, had normal development and minimal signs of WBS. Furthermore, the patients with microscopic 7q11.22-11.23 deletion have more associated features of WBS than those without visible interstitial deletions by high-resolution banding. These results, therefore, emphasize the importance of a combined high-resolution and molecular cytogenetic (i.e., FISH) approach to diagnosis and suggest that the degree to which microscopic/submicroscopic deletions of chromosome 7 extending in beyond the elastin locus may explain some of the phenotypical variability found in WBS.
