Tuhan Hale , Donbaloğlu Zeynep , Kırbıyık Özgür , Parlak Mesut , Demir Korcan

Introduction: Resistance to thyroid hormones is defined as lack of response of peripheral tissues to triiodothyronine (T3) which is the active form of thyroid hormones. In general (85%) a mutation is detected in the thyroid hormone receptor β (THRB) gene and more rarely, the thyroid hormone receptor α (TRHA) gene.Case: A 4.7-year-old boy, was admitted to the pediatric endocrinology outpatient clinic of Akdeniz...

Donbaloğlu Zeynep , Singin Berna , Acar Sezer , Bedel Aynur , Barsal Çetiner Ebru , Aydin Behram Bilge , Parlak Mesut , Tuhan Hale

Objective: We aimed to evaluate the relation between the peak growth hormone (GH) levels on provocative tests and response to recombinant human GH (rhGH) therapy in patients with GH deficiency (GHD).Methods: This was a cross-sectional, single-center, and retrospective study. A total of 518 patients who received rhGH therapy under the age of 16 in the Endocrinology Clinic of Akdeniz University Hospital between 1997 and 20...

Donbaloğlu Zeynep , Bedel Aynur , Barsal Çetiner Ebru , Singin Berna , Aydın Behram Bilge , Tuhan Hale , Parlak Mesut

Objective: We aimed to examine the auxological findings of the girls diagnosed with idiopathic central precocious puberty (CPP) at the end of the Gonadotropin-releasing hormone analogs (GnRHa) treatment and to investigate the effect of related factors on the height gain of those patients.Methods: This study was designed as single-center, descriptive, cross-sectional retrospective study. A total of 43 patients who were di...

Do gonadotropin releasing hormone analogues increase the total body fat mass and body mass index in girls with idiopathic central precocious puberty?

Donbaloğlu Zeynep , Singin Berna , Barsal Cetiner Ebru , Aydin Behram Bilge , Bedel Aynur , Tuhan Hale , Parlak Mesut

Aim: Gonadotropin-releasing hormone analogues (GnRHa) are widely used in the treatment of idiopathic central precocious puberty (ICPP) cases due to premature maturation of the hypothalamus-pituitary-gonad axis. The effect of GnRHa therapy on body weight and fat distribution is controversial in the literature. We aimed to examine the anthropometric measurements and body composition analysis of the girls with ICPP and to investigate the effect of related factors...

Sozaeva Leila , Yanar Eda , Tiulpakov Anotoly , Kareva Maria , Orlova Elizaveta

Objectives: Familial hypocalcemia is a rare autosomal dominant disease characterized by hypercalciuric hypocalcemia. The disorder is caused by heterozygous mutation in the CASR gene that encode a calcium-sensing receptor in parathyroid glands and kidney tubules.Clinical case: The boy was born at term from non-consanguineous parents with normal length and weight. On the second day of life he was admitted to an intensive care department with convu...

Leydig Cell Hypoplasia in Three Siblings in the Same Family

Doneray Hakan , Ozden Ayse , Yakar Omer

Background: Leydig cell hypoplasia (LCH) is a rare disease and one of the causes of male disorder of sexual differentiation (DSD). Inactivating mutations in the luteinizing hormone/chorionic gonadotropin receptor (LHCGR) gene can produce LCH. In this poster, we present three siblings with LCH based on the clinical and laboratory findings and the molecular diagnosis.Cases: A seven-year-old child was brought to our hospita...
