The incidence of atopy in steroid-responsive nephrotic syndrome: clinical and immunological parameters.

Fifty-nine children with steroid-responsive nephrotic syndrome (SRNS), ages ranging from two to 18 years, were studied to determine the incidence of atopy, using both clinical and immunological parameters. Children with SRNS were found to have a significantly higher incidence of atopy both in themselves (z = 2.51, p less than 0.05) and their first-degree relatives (z = 2.34, p less than 0.05). The proportion of children with raised serum IgE levels (60%) and the geometric mean (631 U/ml) in SRNS children were significantly higher than control values, 14.5% and 136 U/ml, respectively (p less than 0.0001). Intra-group comparison showed that children with multiple relapses (more than two relapses) had higher incidence of skin test positivity to house dust mite (p less than 0.01) and to two or more antigens (p less than 0.05). Our data would suggest that atopy may be a predisposing factor in local children with SRNS.

Color perception among different dental personnel.

This study investigated the differences in color perception among distinct groups of dental personnel. Four groups of dental personnel (10 dental technicians, 15 final-year dental students, 15 general practitioners and 10 prosthodontists) were asked to match seven test tabs of shades A1, A4, B2, B3, C2, C4 and D3 (Z100 shade guide, 3M Dental Products, St Paul, MN 55144, USA) against a standard Vita shade guide under similar lighting conditions. The results obtained were computed into L*a*b* values using a small-area colorimeter (Dental Colorimeter, Minolta Camera Pte Ltd). The data were analyzed using one-way ANOVA/post-hoc Scheffe's test at significant level p<0.05. The results showed significant differences in deltaE (color difference) between the dental technicians and the clinicians for shade C4. The significant difference that was observed in deltaE for dark shades between dental personnel was mainly contributed to a disparity in L* values. A significant difference in deltaL* was observed between dental technicians and prosthodontists for shade C4.
