    To evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study. In this cohort, the frequency of small for gestational age (SGA) birth was 33%. The frequency of SGA birth was 4.2% (2/48) in preterm and 36% (174/483) in term neonates (P<0.001). The mean birth length was 1.3cm shorter and mean birth weight was 0.36kg lower than that of the normal population. The mean age at diagnosis was 10.1±4.4 years. Mean height, weight and body mass index standard deviation scores at presentation were -3.1±1.7, -1.4±1.5, and 0.4±1.7, respectively. Patients with isochromosome Xq were significantly heavier than those with other karyotype groups (P=0.007). Age at presentation was negatively correlated and mid-parental height was positively correlated with height at presentation. Mid-parental height and age at presentation were the only parameters that were associated with height of children with TS. The frequency of SGA birth was found higher in preterm than term neonates but the mechanism could not be clarified. We found no effect of karyotype on height of girls with TS, whereas weight was greater in 46,X,i(Xq) and 45,X/46,X,i(Xq) karyotype groups. © 2016 Wiley Periodicals, Inc.

    Central Precocious Puberty Secondary to Adrenocortical Adenoma in a Female Child: Case Report and Review of the Literature
    (Elsevier USA, 2017) Ersoy B.; Kizilay D.; Cayirli H.; Temiz P.; Gunsar C.
    Background Pediatric adrenocortical tumors are rare but significant causes of virilization and peripheral precocious puberty (PPP). Case A 4-year-old girl presented with development of breast, pubic hair, and facial acne. Her bone age was advanced, and her gonadotropin level did not elevate in a gonadotropin-releasing hormone (GnRH) test. High levels of dehydroepiandrosterone sulfate, estradiol, and testosterone, and detection of a tumor in the left adrenal gland of the abdomen using computed tomography led to a diagnosis of PPP due to adrenal tumor. Adrenal adenoma was diagnosed with pathology after the tumor was removed. Ultrasonography detected multicystic ovaries before surgery. Although the androgen levels decreased, high estrogen levels persisted after complete tumor resection. Approximately 1 year after the surgery, the patient's breast development persisted, bone age progressed rapidly, and gonadotropin levels increased in a GnRH test. Central precocious puberty was diagnosed, and treatment with GnRH analogues was started. Summary and Conclusion Adrenal adenoma might present with isosexual PPP as well as virilization in girls. The ovaries should be carefully assessed in these patients. Prolonged exposure to androgen and estrogen might cause ovarian multicysts leading to persistence of high estrogen levels and initiation of central precocious puberty. © 2017 North American Society for Pediatric and Adolescent Gynecology
