Turner syndrome in childhood and adolescence.
This article reviews current patterns of ascertainment, clinical characteristics and quality of care for girls with Turner syndrome, based on a cohort of 100 girls (aged 7-17 years) prospectively evaluated at the National Institute of Child Health since 2001. Approximately 25% were diagnosed prenatally or at birth owing to webbed neck and other features typical of fetal lymphedema, few were diagnosed during early childhood, with the majority undiagnosed until age 9 years or older. Major clinical features included thyroid autoimmunity (51%), congenital cardiovascular anomalies (44%), liver abnormalities (36%), hypertension (34%), hearing loss (30%) and renal anomalies (18%). Of the group, 75% were being or had been treated with growth hormone. These girls were an average of 5 cm taller and significantly less obese than the untreated group. We discuss new guidelines for the initiation of puberty and urgent research needed to promote the health and longevity of girls suffering from Turner syndrome as they become adults.
