Prolonged administration of 200 micrograms of inhaled budesonide daily to young children with severe asthma does not impair growth or pituitary-adrenal function.
The aim of the study was to determine if doxycycline causes tooth staining in young children. A dentist examined 31 randomized children who had been treated with doxycycline and 30 children who had not received doxycycline. Mean age of the children was 10.4 -/+ 2.1 years. Mean age at receipt of the first doxycycline treatment was 4.1 -/+ 1.6 years, and mean number of doxycycline courses was 2.0 -/+ 1.3. No tooth staining was detected by the dentist in any of the children in either group. These findings indicate that treatment with doxycycline in children aged 2 to 8 years is not associated with tooth staining.
We describe 2 Arab patients, both offspring of unrelated consanguineous matings, with unusual facial appearance, severe mental retardation, microcephaly, cortical atrophy, seizures, hypotonia, dwarfism, and recurrent infections with neutrophilia. Neutrophil motility was markedly decreased but the opsonophagocytic activity was normal. Both patients lack the red blood cell (RBC) H antigen and manifest the Bombay (hh) phenotype. Familial endocardial fibroelastosis and familial tetralogy of Fallot segregated independently in one family. The occurrence of the same syndrome in 2 unrelated families suggests that the various aspects of the disorder are the pleiotropic effects of a single mutation. Homozygosity-by-descent for a deletion involving contiguous genes may explain the findings in this syndrome. Alternatively, a mutation which involves an ubiquitous GDP fucose donor rather than the enzyme (alpha 2-L-fucosyltransferase) or its substrate (glcNAc) may account for the pleiotropic manifestations in this syndrome.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
