Introduction:Premature adrenarche (PA) is the most common cause of premature pubic and axillary hair growth before the age of 8 in girls. At the time of diagnosis, the height and bone age of the cases with premature adrenarche were determined to be higher than their peers. The long-term effects of advanced bone age on the final length of the cases are controversial. In this study, it is aimed to share the long-term follow-up data of the cases diagnosed with pr...

Introduction: Gonadal insufficiency is a common long-term endocrinological complication of BMT and is mainly associated with the chemotherapy protocol. In the literature, gonadal insufficiency after BMT varies between 66% -80% in girls and 35-60% in boysAim: to investigate the frequency and the factors affecting gonadal insufficiency in cases with BMT due to non-malignant indications in children or adolescenc...

Background: 3β-hydroxysteroid dehydrogenase (3βHSD) deficiency is a rare form of congenital adrenal hyperplasia (CAH) and caused by loss of function mutations in the HSD3B2 gene. In classic form, affected patients have salt wasting early in infancy and may have ambiguous genitalia in both sexes. Herein we report a nonvirilized female patient with classic form of 3βHSD deficiency due to homozygous S218P mutation in the HSD3B2 gene and classic phenylketonuria....

Deciphering the Functional Mechanisms by which MKRN3 Regulates Puberty Initiation

Background: We recently identified loss-of-function mutations in makorin ring finger 3 (MKRN3) as a cause of familial central precocious puberty (CPP). Analysis of Mkrn3 expression in the arcuate nucleus of mice showed high expression levels in juvenile mice, with a marked reduction prior to puberty onset, suggesting that MKRN3 inhibits puberty initiation. The function of MKRN3 is not known but based on its amino acid sequence, it is predicted to act as an ubiquitin l...

Comparison of efficacy and safety of Leuprolide acetate depot 3.75 mg four-weekly versus 11.25 mg twelve-weekly in girls with central precocious puberty: A randomized-prospective study.

Helvacıoğlu Didem , Demircioğlu Serap , Güran Tülay , Haliloğlu Belma , Gürpınar Tosun Busra , Kahveci Ahmet , Bereket Abdullah

Context: Clinical experience is limited regarding the efficacy of different depot Leuprolide acetate (dLA) treatment protocols in girls with central precocious puberty (CPP).Aim: To compare the 3.75 mg/4 weeks versus 11.25 mg/12 weeks ıntramuscular injection of dLA in suppressing gonadotropins and pubertal development.Subjects and Methods: In a prospective study, 92 girls wit...

Validation of utility of a single LH measurement 40 minutes after depot Leuprolide acetate 3.75 mg and 11.25 mg in assessing gonadotropic activity in girls with CPP: Comparison with a standard GnRH stimulation test at diagnosis and during treatment.

Helvacıoğlu Didem , Demircioğlu Serap , Güran Tülay , Haliloğlu Belma , Türkmen Nilsu , Gurpınar Tosun Buşra , Kahveci Ahmet , Bereket Abdullah

Context: Intravenous Gonadotropin-Releasing-Hormone (GnRH) stimulation test has a central role in evaluating gonadotropic activation in the diagnosis and monitorization of the treatment in patients with central precocious puberty (CPP). However, this test is invasive, laborious, costly and availability of GnRH preparation is limited in some countries.Objective: To evaluate the utility of the LH level measured 40-minutes ...

Aim: 12,13-dihydroxy-9Z-octadecenoic acid (12,13-diHOME) is a lipokine secreted from brown adipose tissue, and it is shown to have positive effects on dyslipidemia. Acute exercise have been shown to lead to an increase in its secretion. It was aimed to investigate the relation of 12,13-diHOME with obesity, exercise and dyslipidemia for the first time in the adolescent age group.Methods: This is a prospective study includ...

CHD7 Mutations in Patients with Anosmic or Normosmic Idiopathic Hypogonadotropic Hypogonadism

Damla Kotan Leman , Anik Ahmet , Mengen Eda , Turan Ihsan , Akkus Gamze , Ozsu Elif , Bereket Abdullah , Nuri Ozbek Mehmet , Yuksel Bilgin , Kemal Topaloglu Ali

Background: Mutations in CHD7 cause a rare multi-organ system disorder, CHARGE syndrome (CS). Genital hypoplasia has been described in 60-80% of reported cases because of idiopathic hypogonadotropic hypogonadism (IHH), which is a result of inadequate GnRH secretion in the hypothalamus. Correspondingly, IHH and anosmia are expected in cases with CHD7 mutation. However, due to the phenotypic spectrum of CHD7, mutations have also be...

Topaloglu A. Kemal , Yildirim Ruken , Damla Kotan Leman , Akkus Gamze , Unal Edip , Turan Ihsan , Dilek Semine , Tastan Mehmet , Gurbuz Fatih , Yuksel Bilgin

BMP4, a member of the bone morphogenetic protein family which is part of the transforming growth factor-beta superfamily, is involved in the embryonic development of various organ and tissues including the cranio-facial structures, olfactory placode, pituitary, eyes, heart, and kidneys. Mutations in this gene are associated with orofacial cleft and microphthalmia in human patients. BMP4 plays an important role in the embryonic development of the GnRH neurons ...
