Pediatric Cushing`s disease due to somatic USP8 mutations

Yanar Eda , Kareva Maria , Kolodkina Anna , Antysheva Zoia , Bogdanov Victor , Peterkova Valentina

Objective: Somatic mutations in the USP8 gene were discovered as the most common genetic defects in corticotropinomas with a frequency of 30 to 60% in adult patients. With regard to pediatric patients, establishing prevalence of USP8 mutations is still challenging due to the rarity of CD incidence in childhood.Aim: To determine the frequency of somatic genetic drivers of CD in a cohort of pediatric patients.<p class=...

Klinefelter Syndrome and Fertility - Current practice in a tertiary Children’s Hospital

Alexopoulou Vasiliki , Bambang Katerina , Senniappan Senthil

Background: Klinefelter Syndrome (KS) is the most common chromosomal anomaly in males associated with infertility. Advances in assisted reproductive medicine have made conception possible for some men with KS, with increasing scientific interest gathered around semen cryopreservation and testicular biopsy for sperm extraction (TESE).Objectives: This project aims to examine the current practice in a paediatric tertiary ho...

A Case of Neonatal Thyrotoxicosis born to mother after thyroidectomy for Grave’s disease

Rim Jeong Hwal , Young Kim Joo

Neonatal thyrotoxicosis is rare and most of the cases are secondary to maternal Graves’ disease. It is usually transient, but can be associated with significant morbidity and mortality if not recognized promptly and treated adequately. We report a case of a 20-day-old female infant who developed thyrotoxicosis with irritability, tachycardia, and relatively poor weight gain. She was born to a mother who took levothyroxine during pregnancy after undergoing a thyroidectomy ...

Keywords: children, primary osteoporosis, next-generation sequencingBackground: Primary osteoporosis (POP) is a rare bone fragility disorder of childhood and is mainly related to osteogenesis imperfecta (OI). However, patients without clinical OI features with recurrent long bone and/or vertebral fractures who comply with the osteoporosis criteria are considered to have non-OI POP. Diagnosis and classification of non-OI ...

Neonatal Diabetes: New Genes, New Mechanisim, New Phenotypes

Ellard S

Recent years have seen significant progress towards defining the genetic aetiology of neonatal diabetes with >20 subtypes identified. It is likely that all cases of neonatal diabetes result from a single gene disorder since markers of autoimmunity associated with type 1 diabetes are rare in patients diagnosed before 6 months.Heterozygous activating mutations in the KCNJ11 and ABCC8 genes encoding the Kir6.2 and SUR1 subunits of the ...

Formation of a Thyroid Gland from Embryonic Stem Cells

Costaglioa S

Induced overexpression of defined transcription factors has been shown to have a directing effect on the differentiation of embryonic stem cells (ESCs) into specific cell types. Nevertheless, protocols promoting coordinated self-assembly of differentiated cells into distinct morphological units with functional properties reminiscent of organs and tissues in vivo are still very sparse. Our group recently reported efficient rescue of hypothyroidism in athyroid mice tran...

Intratubular Large Cell Hyalinizing Sertoli Cell Tumor of the Testis Presenting with Prepubertal Gynecomastia: A Case Report

Tuhan Hale , Abaci Ayhan , Sarsik Banu , Ozturk Tulay , Olguner Mustafa , Catli Gonul , Anik Ahmet , Olgun Nur , Bober Ece

Background: Intratubular Large Cell Hyalinizing Sertoli Cell Neoplasia (ITLCHSCN) resulting from Sertoli cells of the testis are mainly reported in young adults and these are rarely seen in childhood.Objective and hypotheses: In this case report, an eight-and-a-half-year old case presenting with complaint of bilateral gynecomastia since two years, showing no endocrine abnormality in laboratory during 2-years of follow-up, determined to have progression i...

Associations of Vascular Biomarkers and the Somatotrophic Axis with Carotid Ultrasound and Echocardiography Findings in Relation to Turner Arteriopathy

Ucar Ahmet , Oz Fahrettin , Bas Firdevs , Oflaz Huseyin , Nisli Kemal , Tugrul Melike , Darendeliler Feyza , Saka Nurcin , Poyrazoglu Sukran , Bundak Ruveyde

Background: Turner syndrome (TS) is associated with increased arterial stiffness. To date, factors associated with the ontogeny of Turner arteriopathy remain unclear.Objective and hypotheses: To assess the associations of vascular biomarkers and the somatotrophic axis with arterial stiffness indices, and left heart size, in normotensive ‘dipper’ TS.Method: Sixty-one patients with uncomplicated normotentensive &#1...

Cystic Encephalomalacia and Infantile Spasm as a Complication of Transient and Mild Hyperinsulinemic Hypoglycemia

Background: Although it is known that hypoglycaemia could cause severe negative effects on brain development and also infantile spasm, it has not been reported that transient hyperinsulinaemic hypoglycaemia, which spontaneously improves over a short time, may cause infantile spasms. Infantile spasm is a disorder of early childhood typically seen in first year of life characterized by the occurrence of sudden, brief, generally bilateral and symetric motor spasms of muscles of t...

Gulderen Kalay Şenturk Nida , Cakır Aydilek Dağdeviren , Yıldırmak Zeynep Yıldız , Ucar Ahmet ,

Objective: Spexin is a novel peptide implicated in food intake and satiety. Spexin levels are reduced in obese patients.Aim: To evaluate the associations of metabolic syndrome (metS) antecedents with serum spexin levels in obese adolescents.Setting: A university- based tertiary care centre.Patients and methods: Eighty consecutive obese adolescents aged 10-18 y and 80 healthy ...
