Our aim was to determine if there is a relation between birth-weight discordancy and neonatal morbidity and mortality and to test the occurrence of respiratory distress syndrome (RDS) in discordant twins. For 5 yea...
متن کاملDiscordance for ankylosing spondylitis in monozygotic twins.
Three monozygotic twin pairs, each over the age of 45 years, with ankylosing spondylitis are described. In two pairs there is discordance for this disease and in the third pair there is a marked difference in the severity of this disease. These findings provide evidence that environmental factors are necessary not only for the initial development of ankylosing spondylitis, but possibly also for...
