Correlation of 11-oxygenated C19 androgens with the clinical and biochemical characteristics in premature adrenarche

Yavas Abali Zehra , Eltan Mehmet , Helvacioglu Didem , Yaman Ali , Turan Serap , Bereket Abdullah , Guran Tulay ,

Background: Premature adrenarche (PA) is defined as the appearance of pubic and/or axillary hair in girls younger than 8 years old and caused by the rise in adrenal androgen production including dehydroepiandrosterone (DHEA), dehydroepiandrosterone sulfate (DHEAS), and androstenedione (A4). DHEAS≥40 µg/dL is accepted as the biochemical marker of adrenarche. However, adrenals also produce 11-oxygenated C19 androgens such as 11β-hydroxyandrostene...

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...

Objective: Hereditary hypophosphatemic rickets is a rare renal phosphate wasting disorder causing burden on pediatric patients despite conventional treatment of phosphate and calcitriol. The aim of this study is to analyze genetic and clinical variability of children with X-linked hypophosphatemic rickets (XLHR), focusing on short term, long term and pubertal impact of conventional treatment. Design: Retrospective cohort studyMet...

Is Type 1 Diabetes Mellitus Predictable? Investigation of Predictive Markers n Siblings of Probands with Newly Diagnosed Type 1 Diabetes Mellitus

Albayrak Serpil , Karaoglan Murat , Yıldırım Ahmet , Keskin Mehmet ,

Background/Aim: Type 1 diabetes Mellitus (T1DM) often presents with clear clinical signs after a long-term asymptomatic autoimmune process. This long and silent period has been leading to an increase in awareness day by day in order to prevent and predict the development of the disease. Among the well-known genetic and environmental risk factors, close relatives of the index cases constitute a population that is quite suitable for predicting and preventing the...

A Practical Method for the Evaluation of Childhood Hypophysitis: Pituitary Stalk/Basilary Artery Ratio

Torel Ergur Ayca , Şimşek Fatma , Arslan Kubra , Ali Yinanc Mehmet ,

Introduction: Childhood hypophysitis (CH) is an extremely rare entity that has difficulties in definition and displays a wide variety of symptomatology. The volume and shape of pituitary gland may increase in physiological periods such as puberty and pregnancy, it may also change in various neuroendocrine and psychiatric diseases. It is important to distinguish physiological changes observed in the pituitary, especially in puberty, from hypophysitis.F...

Clinical and molecular genetic characteristics of 98 patients with congenital hypopituitarism: A single-center experience

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

Background: Congenital hypopituitarism (CH) refers to a deficiency of one or more pituitary hormones resulting from variants in genes encoding transcription factors for pituitary development. CH cases are mostly sporadic but 5-30% can be familial. Genetic etiology is not determined in most cases. The aim of our study was to evaluate the genetic features of CH using different molecular and/or molecular cytogenetic techniques.Subje...

Childhood obesity has emerged as an important public health problem in the worldwide. It is important to follow these cases in multidisciplinary centers at an early age in order to prevent metabolic and psychosocial comorbidities that may develop. Bariatric surgery is a treatment method whose frequency is increasing in adolescent obesity. In the study, the 6-month results of the patients who applied to the obesity center were shared.Materials-Met...

Introduction: Cortisol homeostasis dysregulation has been associated to essential hypertension in adults. Higher levels of cortisol have been described in preterm-born individuals, who have also a higher risk of hypertension at younger ages. Several enzymes modulate peripheric cortisol metabolism. The 11b-hydroxysteroid dehydrogenase (11b-HSD) type 2 metabolizes cortisol into cortisone, preventing mineralocorticoid receptors’ activation by cortisol. The i...
