Longitudinal analyses of polysomnographic variables, serum androgens, and parameters of glucose metabolism in obese adolescents with polycystic ovarian syndrome.

Purpose: The prevalence of obstructive sleep apnea syndrome (OSAS) is clearly increased in adults with polycystic ovarian syndrome (PCOS), whereas OSAS does not seem to be frequent in adolescents with PCOS, pointing towards the fact that some patients with PCOS develop OSAS in the further course of the disease. We therefore aimed to analyze the changes of polysomnographic variables in obese adolescents with PCOS in a longitudinal analysis.

Methods: Fifteen adolescents with PCOS (age 15.

Diagnostics and management of sleep-related respiratory disturbances in children with skeletal dysplasia caused by FGFR3 mutations (achondroplasia and hypochondroplasia).

To evaluate the frequency of clinical indicators for sleep-related respiratory disturbances (SRD) and the polysomnographical manifestations of these disorders in children with skeletal dysplasia caused by FGFR3 mutations. From January 1990 to January 2009, 24 patients (22 achondroplasia, 2 hypochondroplasia; 13 boys, 11 girls; age 8 days to 15 years, median age 3.0 years) were examined, including a semi-structured interview, a clinical examination, and a polysomnographic sleep recording (65 polysomnographic sleep recordings (PSG) in 24 patients).

A comparison of polysomnographic variables between adolescents with polycystic ovarian syndrome with and without the metabolic syndrome.

Background: We aimed to determine the differences in polysomnographic variables between obese adolescents with polycystic ovarian syndrome (PCOS) with and without metabolic syndrome, as the prevalence of obstructive sleep apnea syndrome (OSAS) is increased in adults with PCOS, OSAS has been regarded as a manifestation of the metabolic syndrome, and the prevalence of metabolic syndrome is increased in patients with PCOS.

Methods: Fourteen obese adolescents with PCOS and metabolic syndrome [15.7 years ± 1.

The impact of insulin resistance and hyperandrogenemia on polysomnographic variables in obese adolescents with polycystic ovarian syndrome.

Purpose: We aimed to determine the impact of insulin resistance and hyperandrogenemia on polysomnographic variables in obese adolescents with polycystic ovarian syndrome (PCOS), as studies in adults with PCOS suggest that parameters of glucose metabolism and serum androgens are related to respiratory polysomnographic variables (RPV), and the symptoms of PCOS usually begin around menarche.

Methods: We divided our study group of obese adolescents with PCOS according to HOMA-index and in a second analysis according to free androgen index (FAI). Study group A consisted of 14 girls with HOMA-index <4, study group B of 17 girls with HOMA-index >4.

Relationships between polysomnographic variables, parameters of glucose metabolism, and serum androgens in obese adolescents with polycystic ovarian syndrome.

The aim of this study was to compare polysomnographic variables of obese adolescents with polycystic ovarian syndrome (PCOS) to those of healthy controls and to analyse whether polysomnographic variables correlate to parameters of body weight/body composition, to serum androgens and to parameters of glucose metabolism. Thirty-one obese adolescents with PCOS (15.0 years ± 1.
