Introduction: Premature adrenarche (PA) is a benign clinical condition characterized by the early appearance of pubic and/or axillary hair. Non-classical form of congenital adrenal hyperplasia (CAH) should be ruled out in children with premature pubarche. This study aims to demonstrate the significance of clinical and laboratory data in differentiating between PA and CAH.Materials and Methods: This study includes prepube...

Kahveci Ahmet , Helvacıoglu Didem , Yavas Abalı Zehra , Tugba Canbaz Aylin , Gunay Aylin , Bereket Abdullah , Demircioglu Turan Serap

Aim and Method: Achondroplasia is the most common form of short-limbed dwarfism, characterized by mutations in the FGFR3 gene. Vosoritide, a C-type natriuretic peptide analog, has shown promise in promoting linear growth in children with achondroplasia. This study aims to present the real-life experiences of using vosoritide in children diagnosed with achondroplasia.Method and Results: A prospective study was conducted o...

Bahar Balaban Berber İlkay , Günel Ceren , Tuzcu Göksel , Ünüvar Tolga , Anık Ahmet

Introduction: The most common extra-thyroidal manifestation of Graves' disease is ophthalmic involvement. Pediatric Graves' ophthalmopathy (GO) occurs in approximately one-third of cases with pediatric Graves' disease. However, the frequency of severe GO is quite rare compared to adults, and in this case series, two different GO cases, one severe and one unilateral/asymmetric, are presented.Case 1: A 14-ye...

Dağdeviren Çakır Aydilek , Yıldız Yıldırmak Zeynep , Eren Simge , Mısırlı Özdemir Ebru , Özdemir Mustafa , Ucar Ahmet

In children, autoimmune thyroiditis is often diagnosed with signs and symptoms such as goiter, short stature, and constipation. Delayed diagnosis of hypothyroidism may result in atypical signs and symptoms at presentation, depending on the severity of hypothyroidism. Von Willebrand disease (vWD) is the most common bleeding disorder caused by the quantitative or qualitative deficiency of von Willebrand factor (vWF). Acquired vWD (avWD) is a disorder characterized by low levels ...

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...

Background: Hypersensitivity reactions to gonadotropin releasing hormone analogues (GnRHa) is a rare but serious side effect . Besides, local reactions, urticaria, anaphylaxis, serum disease, Henoch Schonlein Purpura (HSP) have been reported during GnRHa treatment.. Clinicians should be aware of the potential association of GnRHa with systemic hypersensitivity reactions.Case reports: Here, we report nine girls with syste...

Background: Vitamin D Dependent Rickets Type IA (VDDR-IA) is the most common type of VDDR and caused by mutations in CYP27B1. Here, we aimed to analyze the genotypic and phenotypic features of our VDDR-IA patients.Materials and Methods: The patients with a clinical diagnosis of VDDR-IA were enrolled and analyzed for CYP27B1 gene mutations.Results: 12 (5 males) pat...

A Rare Cause of 46, XX ovotesticular DSD: Tetragametic Gonadal Chimerism

Uçar Ahmet , Güran Tülay , Eren Funda , Dokucu Ali Ihsan , Sahin Süleyman , Tanik Canan

Introduction: Virilization and hirsutism are clinical findings of androjen excess in females mostly due to polycystic ovary syndrome, although androgenic drugs, nonclassic congenital adrenal hyperplasia and androgen secreting adrenal/ovarian lesions are also implicated. 46, XX ovotesticular disorder of sex development (DSD) is the rarest form of DSD with an incidence of less than 1 in 20000.Case report: A 15-year-old ado...
