Introduction: Aggrecan, a chondroitin sulfate proteoglycan encoded by the ACAN gene, is an important structural component of the cartilage matrix. Variants in the ACAN gene are associated with a group of skeletal dysplasias called aggrecanopathy, which shows a broad phenotypic spectrum. It has been reported that some heterozygous variants in this gene are responsible for the etiology of familial or idiopathic short stature located at the lightest end of the sp...

Entrance: HOXA gene deletions cause an appearance characterized by short stature, mild developmental delay, characteristic face, small hands and feet, short and large thumbs, and urogenital malformations. Clinical signs may vary according to the content of the deletion region.Case: The case applied to our clinic with the complaint of short stature. It was learned that the patient was born at term 2500 gr and had bilatera...

Background: Bone morphogenetic protein 15 (BMP15), is an oocyte-specific growth factor, that regulates folliculogenesis and ovulation rate. It is encoded by the BMP15 gene (chromosome Xp11.2), in which heterozygous missense variants in the precursor or mature peptide cause primary ovarian insufficiency (POI) with the dominant-negative effect. BMP15-related ovarian dysgenesis (OD) constitutes 1.5-2.0% of POI. The underlying mechanism ...

Introduction: 17 β-Hydroxysteroid Dehydrogenase Type 3 (17β-HSD3) enzyme provides the conversion of ∆4-Androstenedione (A) to testosterone (T) in testicles. 17β-HSD3 deficiency is a rare autosomal recessive cause of 46,XY disorders of sexual development (DSD) and is the most common form of testosterone biosynthesis defects. The external genitalia can vary from normal female appearance to atypical genitalia.C...

Introduction: Although thyroid nodule is seen less frequently in childhood than in adults, it is more likely to be malignant. The aim of this study was to examine the characteristics of the patients followed up for thyroid nodules and to define the patients with malignant potential by laboratory, radiological and cytological evaluations.Method: 100 patients (F/M:63/37) with thyroid nodules followed up in Pediatric Endocr...

Background and Aims: Irisin is a newly discovered adipomyokine that occurs by the cleaved from a transmembrane protein called "Fibronectintype III domain containing 5" (FNDC5).Previously, there was a change in irisin levels in different prepubertal and pubertal stages.Although the mechanisms that trigger the onset of puberty cannot be explained yet, there is a hypothesis that peripheral adipose tissue and adipokines secreted there may induce the initia...

Background: Limbic encephalitis (LE) is a neurological disorder characterized with amnesia, seizures, personality changes. LE is usually considered as paraneoplastic disorder. Infections, paraneoplastic disorders and autoimmunity should be considered in LE etiology. Association of type 1 diabetes mellitus and LE is very rare. Here in we report a patient who was diagnosed with type 1 diabetes mellitus (T1DM) six months after LE occurrence.Case: A 17-year-...

Background: Serum sickness should be considered for the symptoms such as fever, arthralgia and urticaria existing 2–3 weeks after drug administration. Serum sickness is prototype of type 3 hypersensitivity reactions. Nephropathy and vasculitis may occur and main finding is hypocomplementemia. Several drugs such as antibiotics were reported as the reason of serum sickness disease.Objective and hypotheses: According to our knowledge, herein we report ...

Background: Stevens-Johnson Syndrome (SJS) is an acute life-threatening dermatosis characterized by conjunctivitis, oral ulcerations, fever and erythematous macules. The most important etiological factors are infections and drugs including anticonvulsants and nonsteroidal anti- inflammatories.Objective and hypotheses: Cases with both SJS and type 1 diabetes mellitus have been reported rarely in the literature. Herein, we report a diabetic case of recurre...

Objectives: Age at menarche depends on genetic, environmental, epigenetic and other factors. Studies have shown that aspects of perinatal history, including birth weight, mode of delivery (caesarian section or vaginal delivery) and gestational week at birth influence the onset of puberty. The purpose of this study was to record the age at menarche in a sample of Greek girls and to correlate it with their perinatal history, the mothers’ age at menarche, t...
