    Is There A Secular Trend Regarding Puberty In Children With Down Syndrome?
    (2022) Erdogan, Furkan; Guven, Ayla; 36457553
    IntroductionThere are very few studies on the age of onset and end of puberty in children with Down syndrome (DS). Also, data regarding the course of puberty in these children compared to their healthy peers is limited. Moreover, there is limited information regarding the effects of factors such as obesity and hypothyroidism on the puberty process in children with DS. Our aim in our study is to determine whether the pubertal development of children with DS differs from their healthy peers and from previous studies conducted with DS children. MethodsThe medical records of DS children were examined retrospectively. The anthropometric measurements and the age of onset of pubertal stages, and menarche were recorded. The patients' age at puberty onset, the puberty processes, and age at menarche were compared with their healthy peers and previously published data on children with DS. ResultsOf the 140 Down syndrome patients followed in our clinic, 51 of whom with puberty constituted the study group. The mean age of onset of puberty was 10.3 +/- 1.0 years in our group (10.0 +/- 0.8 years for girls, 10.6 +/- 1.2 years for boys, respectively). Obesity occurred in 46% of pubertal girls with DS. The age of menarche in girls with DS was 11.8 +/- 0.7 years. The menarche age of girls with DS was significantly different from healthy girls. In the DS boys, only the Tanner V stage ages were different from the healthy children. True- precocious-puberty was detected in three children. ConclusionAlthough breast development begins later in females with DS than in their healthy peers; menarche is detected earlier than in their peers and a tendency towards obesity in the whole population. While the age of pubertal onset was similar to healthy children in male patients, our findings suggest that their puberty duration is longer.

    Etiology of Increased Referrals for Evaluation of Early Puberty in a Tertiary Care Center in Turkey: True Precocious Puberty, Obesity, or Parental Anxiety and Lack of Knowledge?
    (2021) Cemeroglu, Ayse Pinar; Kaval, Damlanur; Ozcan, Ozan; 0000-0002-1653-7932; 0000-0002-9421-0855; 0000-0002-3430-5203; 33889682
    There has been a global increase in pediatric endocrinology referrals for the concerns of early puberty. The objective of this study was to determine the reasons behind this increase. A retrospective cross-sectional study was designed to analyze the clinical characteristics of patients seen for the concerns of early puberty in pediatric endocrinology clinic of a tertiary care center (Study A). Additionally, a prospective questionnaire study was designed to assess the knowledge and concerns of the mothers regarding the timing of puberty in girls (Study B). In study A, of the 305 girls, 42.9% were overweight/obese, 68.5% either had normal pubertal development for age or were prepubertal, 1 had non-classic congenital adrenal hyperplasia, and 2 had central precocious puberty. Of the 36 boys, 56% were overweight/obese, 64% either had normal pubertal development for age or were prepubertal, and 1 had non-classic congenital adrenal hyperplasia. In study B, 95% of the participants thought the girls have been developing earlier, over 10% considered the first sign of puberty to be normal after the age 14 years and 12.4% considered menarche to be normal after age 14 years. The common sources of anxiety for the participants regarding the earlier timing of puberty were psychosocial issues and short final height. In conclusion, many parents had wrong beliefs/information about the normal timing of puberty and were concerned about precocious puberty in girls. Education of parents about the normal timing of puberty may help avoiding unnecessary referrals, parental anxiety, and financial burden to the society.
