          Abstract

          Introduction:

          The incidence of Hashimoto's thyroiditis among patients who have Turner syndrome (TS) has increased, but Graves’ disease (GD) in patients with TS is rarely reported. Here we report a rare case of TS with GD accompanied by hypogonadotropic hypogonadism.

          Patient concerns:

          We report the case of a 16-year-old girl who complained nervousness, fatigue, marasmus, heat intolerance, sweating, palpitation, and tremor lasting for more than a month. She had no medical history.

          Diagnosis:

          TS was diagnosed of the results of karyotyping demonstrated a gene karyotype of 46, X, i (X)(q10). GD was also diagnosed in this patient following the detection of thyroid function analysis.

          Interventions:

          Methimazole was administered after identification of GD. Due to the absence of secondary sex characteristics, the patient was given a conjugated estrogen preparation for 1 year, followed by the addition of estradiol cyproterone tablets for the onset of menstruation.

          Outcomes:

          The hyperthyroidism symptoms of the patient had improved both clinically and laboratory tests after methimazole therapy. She was treated with estrogen and estradiol cyproterone, and the uterus and secondary sexual characteristics of the patient developed during 1 year follow-up.

          Conclusion:

          TS generally presents as hypergonadotropic hypogonadism. However, hypogonadotropic hypogonadism cannot completely exclude TS. The diagnosis of this disease depends on chromosomal examination. The disease should be detected and treated as early as possible to improve life quality of the patient.

          Epidemiological, endocrine and metabolic features in Turner syndrome.

          Turner syndrome is one of the more common genetic disorders, associated with abnormalities of the X chromosome, and occurring in about 50 per 100 000 liveborn girls. Turner syndrome is usually associated with reduced adult height, gonadal dysgenesis and thus insufficient circulating levels of female sex steroids, and infertility. A number of other signs and symptoms are seen more frequently with the syndrome. Morbidity and mortality are increased. The average intellectual performance is within the normal range. A number of recent studies have provided new insights with respect to epidemiology, cardiology, endocrinology and metabolism. Treatment with GH during childhood and adolescence allows a considerable gain in adult height, although very-long-term consequences of this treatment are not clear. Puberty has to be induced in most cases, and female sex hormone replacement therapy is given during the adult years. The proper dose of hormone replacement therapy (HRT) has not been established, and, likewise, benefits and/or drawbacks from HRT have not been thoroughly evaluated. Since the risk of cardiovascular and endocrinological disease is clearly elevated, proper care during adulthood is emphasized. In summary, Turner syndrome is a condition associated with a number of diseases and conditions which are reviewed in the present paper.

            Turner syndrome: diagnosis and management.

            Turner syndrome occurs in one out of every 2,500 to 3,000 live female births. The syndrome is characterized by the partial or complete absence of one X chromosome (45,X karyotype). Patients with Turner syndrome are at risk of congenital heart defects (e.g., coarctation of aorta, bicuspid aortic valve) and may have progressive aortic root dilatation or dissection. These patients also are at risk of congenital lymphedema, renal malformation, sensorineural hearing loss, osteoporosis, obesity, diabetes, and atherogenic lipid profile. Patients usually have normal intelligence but may have problems with nonverbal, social, and psychomotor skills. Physical manifestations may be subtle but can include misshapen ears, a webbed neck, a broad chest with widely spaced nipples, and cubitus valgus. A Turner syndrome diagnosis should be considered in girls with short stature or primary amenorrhea. Patients are treated for short stature in early childhood with growth hormone therapy, and supplemental estrogen is initiated by adolescence for pubertal development and prevention of osteoporosis. Almost all women with Turner syndrome are infertile, although some conceive with assisted reproduction.

              Prevalence of thyroid dysfunction in Turner's syndrome: a long-term follow-up study and brief literature review.

              Thyroid dysfunction, especially hypothyroidism caused by Hashimoto's thyroiditis is more frequently observed in girls with Turner's syndrome (TS). The aim of the present study was to evaluate prevalence, etiology, karyotype distribution and age at onset of thyroid pathology in girls with TS. Data recorded in 84 girls with TS attending our clinic were analyzed. The mean age +/- standard deviation [SD] at their initial evaluation was 10.3 +/- 3.7 years (range, 0.5 to 19 years) and the mean period of observation was 8.4 +/- 4.4 years. The thyroid function had been evaluated at least once per year in all patients and thyroid autoantibodies (ATA) were available in 51 (60.7%). Hypothyroidism was detected in 24% of the studied subjects and hyperthyroidism in 2.5%. Elevated values of thyroid autoantibodies were detected in 42% of girls with TS, whose ATA had been determined, and 65% had hypothyroidism. Thyroid dysfunction was first noted after the age of 8 years with no difference in the distribution of new cases at the different ages or pubertal stages. There was no difference in the incidence of thyroid dysfunction related to the type of karyotype abnormality. Thyroid dysfunction is more frequently encountered in girls with TS (hypothyroidism: 24% in the total group and 65% in those with positive ATA, hyperthyroidism: 2.5%). Thyroid dysfunction was observed after the age of 8 years with no difference in the occurrence of new cases in the various age groups thereafter. Hence, thyroid function should be evaluated yearly in girls with TS past the age of 8 years and more frequently in those with positive thyroid autoantibodies.
