Interim analysis of the prospective evaluation of putatively influential factors associated with the timing and duration of honeymoon phase in newly diagnosed pediatric patients with Type 1 Diabetes

Özdemir Mustafa , Uçar Ahmet

Background: Type 1 Diabetes (T1D) is a chronic condition characterized by the autoimmune destruction of pancreatic beta cells, leading to insulin deficiency. The honeymoon phase (HP), a period of partial clinical remission shortly after the diagnosis, presents a significant opportunity for intervention. Understanding the factors influencing the duration and onset of HP could inform treatment strategies and potentially prolong the remission period.<p class=...

Premature ovarian failure in a tall adolescent

Dağdeviren Çakır Aydilek , Çetinçelik Ümran , Uçar Ahmet

Introduction: Primary ovarian failure (POF) is traditionally defined as cessation of menstruation prior to 40 yr of age and diagnosis is confirmed by elevated serum FSH levels (often above 40 IU/L). It is known that 0.1% of the population is affected with POF before age 30 yr. Here, we report a case with POF, who presented wit tall stature due to structural abnormalities in X chromosome.Case Report: A 13.5 year-old-adole...

Evaluation Of The Growth Hormone-Insulin like Growth Factor1 Axis And Serum Fibroblast Growth Factor 21 Levels As Related To Stature In Children And Adolescents With Coeliac Disease Adherent To Gluten Free Diet

Kaya Fırat , Urgancı Nafiye , Merve Usta Ayşe , Çelik Sedanur , Uçar Ahmet

Background: Coeliac disease(CD)is a common cause of stunted growth. Despite adherence to gluten-free diet(GFD), short stature may persist in some patients with CD. Studies investigating the growth hormone(GH)-insulin like growth factor-1(IGF1) axis in children and adolescents withCDare scant and inconclusive. Fibroblast growth factor-21(FGF-21)is a181amino acid polypeptide that plays a role in growth, lipid and glucose metabolism. The inhibitory effects of FGF...

A Case with Alstrom Syndrome with a Novel Pathogenic Variant In ALMS1 gene as a Rare Cause of Diabetes Mellitus

Dağdeviren Çakır Aydilek , Gizem Bolaç Özyılmaz Leyla , Uçar Ahmet

Introduction: Alstrom syndrome (ALMS) is an autosomal recessive disorder characterized by multiple organ involvement, including progressive cone-rod dystrophy, sensorineural hearing loss, childhood obesity, and type 2 diabetes mellitus. Pathogenic variants in the ALMS1 gene are the known cause for the occurrence of this devastating condition. Here, we reported a case of Alstrom syndrome with a novel homozygous variant in the ALMS gene, who presented to our cli...

A Rare Cause of Primary Ovarian Insufficiency: Novel Homozygous c.2120G>C(p.Arg707Pro) Pathogenic Variant in the MCM8 Gene

Eren Simge , Türkyılmaz Ayberk , Özdemir Mustafa , Uçar Ahmet

Introduction: Primary ovarian insufficiency (POI) is a condition characterized by amenorrhea with elevated FSH and LH levels as a result of ovarian dysfunction. Ovarian failure is a very rare condition in pediatric population. Genetic syndromes (Turner, Fragile X syndrome) or malignancy treatment are the main reasons. The minichromosome maintenance complex component 8 (MCM8) gene is responsible for the repair of DNA double-strand breaks;MCM8 is a rare cause of...

Evaluation of the Frequency and Time Course of Side Effects Asscociated With Metformin Use In Obese Adolescents As Related to Weight Loss: A Prospective Single-Centre Observational Study

Mısırlı Özdemir Ebru , Dağdeviren Çakır Aydilek , Bilge Özakçe Mehmet , Uçar Ahmet

Background: Metformin is a well-known biguanide approved for treatment of Type2 Diabetes. Metformin is not considered as an anti-obesity drug despite its common off-label use. Currently, there are no data regarding the profile of metformin related gastrointestinal side effects (MRGSE) in obese adolescents.Aim: To identify the frequency and time course of MRGSE in obese adolescents and assess the presence of any associati...

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...

Background: Myo-inositol(MI)is a polyol involved in intracellular signaling pathways of insulin and MI has been used orally for therapeutic purposes in girls and adult women with polycystic ovary syndrome(PCOS)with variable success. As yet, serum MI levels have not been assessed in girls with PCOS.Aim: Our primary goal was to compare serum MI levels in girls with PCOS with those in healthy peers. Secondary goal was to in...

Introduction: Gynecomastia is common in boys at early-mid puberty, while prepubertal gynecomastia is a rare condition. Sertoli cell tumors (SCTs) account for 2% of prepubertal testicular tumors. Most of the SCTs in prepubertal boys, which are generally bilateral and diffuse, are in the content of Peutz-Jeghers Syndrome (PJS) or other familial syndromes (Carney complex). Large cell calcifying Sertoli cell tumor (LCCSCT) is a variant of SCT and is seen in PJS. I...

Three Cases with Familial Short Stature: Leri-Weill Syndrome

Ayranci Ilkay , Çatli Gönül , Eroğlu Filibeli Berna , Manyas Hayrullah , Bekir Kutbay Yaşar , Koç Altuğ , Nuri Dündar Bumin

Introduction Objective: The SHOX gene is located in pseudoautosomal region of chromosomes of Xp22.33 and Yp11.32. It plays role in proliferation and differentiation of epiphyseal chondrocyte. Leri-Weill syndrome is observed with loss of an allele, while missense mutations lead to idiopathic short stature without any dysmorphic findings. This report presents clinical features of three cases diagnosed with Leri-Weill syndrome, and their responses to rhGH treatme...
