Abstract
BACKGROUND: Turner syndrome is characterized by a great variability of clinical manifestations caused by a total or partial loss of X-chromosome. PATIENTS AND METHODS: A retrospective, descriptive study of the diagnosis, course, and current status of patients with Turner syndrome followed up at our section over the past 40 years, based on review of medical records supplemented with a telephone survey. RESULTS: Forty-five female patients with a current mean age of 22.95years (range 2-38) and a mean age at diagnosis of 4.71 were included. Sixty-three percent of them showed a mosaic karyotype. Short stature was the most common reason for consultation (54%), with increased prenatal diagnosis in most recent cases. Seventy-two percent have been treated with growth hormone, together with oxandrolone in 26%. Final stature was short in 69% of patients. Gonadal failure was found in 66%; most of whom received replacement therapy. Three patients achieved pregnancy by oocyte donation. The 31 adult patients are mainly monitored by the endocrinology (37.5%) and/or gynecology (34.4%) departments. As regards psychosocial aspects, 22% required support during school, and 80% completed middle to high level education. Two patients died, one due to dissecting aortic aneurysm and the other one, who had multiple pathological conditions, from respiratory failure. CONCLUSIONS: Short stature is the main cause of diagnosis in patients with Turner syndrome; most cases show genetic mosaicism. The most common clinical manifestations include short stature and gonadal failure. Eighty percent of patients complete middle or high education. In adulthood, follow-up is irregular, sometimes scarce, and clearly improvable.
