[Juvenile struma and development]

Different aspects of the juvenile struma development in children are studied. The object of the investigations were puplis: 260 with juvenile struma and 240--without, aged from 8 to 17. The following indices were used: 1. physical growth--height, bodyweight, growth rate, annual mark in gymnastics; 2. mental development--mean annual marks at school; 3. sexual development--menarche rhythm and duration of menses in girls. All data were processed statistically by rank, non-parametric, variation and despersion analysis. The author thinks that the juvenile struma does not influence the normal progress of growth but is significantly more frequent among rapidly growing-up girls. He concludes that faster parapuberal growth might be the cause of juvenile struma origination.
