Serum IgE in newborns undergoing exchange transfusion.

Serum IgE was studied in a group of 20 newborns, ten males and ten females, with neonatal non-immunologic jaundice before and after exchange transfusion and in a control group without jaundice or other immunologic problems. Serum IgE was significantly higher in the study group than in the control group (P less than .005). After exchange transfusion there was a further increase (P less than .005). These changes do not seem to be due to the IgE content of the transfused blood. It is suggested that neonatal jaundice and/or exchange transfusion may stimulate the IgE synthesis in the newborn.

A dermatoglyphic study of a group of Sicilian children with fragile-X syndrome.

In a dermatoglyphic study of 14 fra(X) boys (compared with a control group of 191 normal schoolboys), we observed the following statistically significant (p less than 0.01) differences: 1) lower frequency of ulnar loops on the fingertips, particularly on the 2nd and 3rd fingers, with a corresponding increase of whorls; 2) transverse course of main line A; 3) increased frequency of abnormal palmar creases. The log score index of Simpson et al [1984] identified 71.4% of our patients and that of Rodewald et al [1986] 64.2%. The different values of these indexes can probably be attributed to ethnic differences. We think that by combining the results of dermatoglyphic analysis from several centers a more discriminatory log score index can be obtained.

Lipoid proteinosis: a case report.

An 8-year-old Italian boy, born to consanguineous parents, with clinical, histopathologic, and ultrastructural findings of lipoid proteinosis is reported. The main signs of the syndrome-papulonodular, hyperkeratotic and verrucous lesions distributed over the skin of the head and extremities, hoarseness, and dysphagia-were present in the child. The mother had papulonodular lesions on her hands and also complained of slowness in healing.
