46,XY DSD due to biallelic DHX37 gene mutations

Eltan Mehmet , Helvacioglu Didem , Ates Esra Arslan , Abali Zehra Yavas , Turan Serap , Bereket Abdullah , Guran Tulay

Background: DEAH-box protein DHX37, encodes an RNA helicase, is involved in ribosome biogenesis. Monoallelic mutations in DHX37 gene have recently been identified in 46,XY differences/disorders of sex development (DSD) patients with nonsyndromic gonadal dysgenesis as well as testicular regression, while biallelic mutations have been associated with microcephaly and structural brain abnormalities. Here, we present a patient with penoscrotal hypospadias and bil...

Gacemer Hazal , Gurpinar Tosun Busra , Yavas Abali Zehra , Helvacioglu Didem , Haliloglu Belma , Turan Serap , Bereket Abdullah , Guran Tulay

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is widely used to assess patients for adrenal insufficiency. However, the predictive power of basal cortisol for the performance of LDST is not clear.Objective: To determine the appropriate basal serum cortisol cutt-off values that predict a positive or negative LDST.Design: A single-centre retrospective study...

Clinical and genetic evaluation of patients with maturity onset diabetes of the young (MODY) : Single center experience

Hande Turan , Bayramoglu Elvan , Gunes Kaya Didem , tarcin Gürkan , Bingöl Aydın Dilek , Ercan Oya , Evliyaoglu Olcay

Purpose: MODY is a monogenic diabetes with autosomal dominant inheritance that usually occurs in adolescence or young adulthood. It constitutes 1% of diabetes cases in childhood. The diagnosis of MODY is very difficult due to genetic heterogeneity, rarity, and clinical overlap with other diabetes types. In recent years, the diagnosis of MODY has become easier with genetic developments. On the other hand, misinterpretation of results can cause confusion. In thi...

Vuralli Dogus , Ozon Z. Alev , Gonc E. Nazli , Ardicli Didem , Jalilova Lala , Gulcek Omer Nazım , Alikasifoglu Ayfer ,

Introduction: Global variations in epidemiology of type 1 diabetes (T1D) exist worldwide. This study is designed to determine the demographic and clinical characteristics of T1D in the past three decades, and to analyze changing trends in epidemiology over the past 50 years.Methods: Epidemiological and clinical characteristics of 925 patients with T1D were analyzed in three decades between 1991 and 2019. In addition, pre...

The role of body composition and appetite-regulating hormones in idiopathic central precocious puberty and their changes during GnRH analogue therapy.

Tarçın Gürkan , Bayramoğlu Elvan , Güneş Kaya Didem , Karakaş Hasan , Turan Hande , Evliyaoğlu Olcay

Aim: This study aimed to compare the levels of appetite-regulating hormones (ghrelin, leptin, peptide-YY (PYY), neuropeptide-Y (NPY)) in girls with idiopathic central precocious puberty (ICPP) before treatment with prepubertal girls, and to evaluate changes in these hormone levels and body composition during leuprolide acetate (LA) treatment.Methods: This prospective, cross-sectional study included girls with ICPP, isola...

Physician and Family Awareness in the Diagnostic Process of Newly Diagnosed Type-1 Diabetes Mellitus

Kahveci Ahmet , Helvacıoglu Didem , Kelestemur Elif , Kurt Ilknur , Turan Serap , Guran Tulay , Bereket Abdullah , Haliloglu Belma

Aim and Method: Diagnosis of type 1 diabetes (T1DM) may be delayed in some children, despite seeking medical care by the family. In this prospective/observational study, the time and process from consulting with a doctor to getting diagnosed with diabetes was investigated in patients hospitalized for newly diagnosed T1DM between 2021-2022.Results: During the study period total of 114 newly diagnosed T1DM patients (49%F, ...

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...

Basal Ganglia Calcification in Children with Hypoparathyroidism and Pseudohypoparathyroidism: Characterization of Relationships and Clinical and Laboratory Findings

Gurpinar Tosun Busra , Kurt Ilknur , Helvacioglu Didem , Yavas Abali Zehra , Guran Tulay , Bereket Abdullah , Jüppner Harald , Turan Serap

Background: Hypoparathyroidism (HP) and pseudohypoparathyroidism (PHP) are conditions associated with basal ganglia calcification (BGC) which is thought to be caused by high serum calcium-phosphorus product and inadequate management of hypocalcemia. Novel mechanisms have recently been proposed for phosphate sensing and transport. However, the exact pathophysiology of BGC remains to be elucidated.Objective: To gain furthe...
