Background: 46,XX gonadal dysgenesis is a rare condition linked to delayed puberty, absence of spontaneous pubertal development, and primary amenorrhea related to hypergonadotropic hypogonadism (Hh). External genitalia are typically female with no ambiguity. Although ovarian development is an active process with multiple gene involvement, the genetic etiology of this condition is usually unknown. DCAF17 has recently been implicated in the development ...

A Case of Cushing’s Syndrome Due to Adrenocortical Adenoma with Pubarche and Obesity

Gurbuz Fatih , Cayir Atilla , Karakus Esra , Demir Rabia , Demirel Fatma , Senel Emrah

Background: Adrenocortical tumors in childhood represent very rare about 0.2% of all pediatric malignancies. Cushing’s syndrome (CS) is characterized by clinical features caused by autonomous excessive glucocorticoid production from adrenal cortex. In ACTH-independent CS, the most common cause is unilateral cortisol-producing adrenocortical adenoma.Objective and hypotheses: Fifteen months old girl was admitted with gradually gain weight, pubarche, a...

Potential Role of Vitamin D in Pathogenesis of Acute Rheumatic Fever

Hanedan Onan Sertac , Demirbilek Huseyin , Aldudak Bedri , Bilici Meki , Demir Fikri , Muhtar Yilmazer Murat

Background: Acute rheumatic fever (ARF) is a non-suppurative complication of Group A beta-hemolytic streptococcus pharyngitis. The underlying mechanisms have not been fully elucidated. A series of autoimmune processes are thought to be involved in pathogenesis. Low vitamin D levels have been reported in various autoimmune diseases.Objective and hypotheses: The aim of the present study is to evaluate the association of vitamin D levels and its impact on t...

Higher-Than-Conventional Subcutaneous Regular Insulin Doses Following Diabetic Ketoacidosis are Associated with Better Short-term Glycemic Control

Bag Ozlem , Tunc Selma , Nalbantoglu Ozlem , Ecevit Cigdem , Ozturk Aysel , Ozkan Behzat , Demir Korcan

Background: While some guidelines recommend 0.5–1.0 units/kg per day of subcutaneous insulin following resolution of diabetic ketoacidosis (DKA), up to 2 units/kg/day are used in various centers.Objective and hypotheses: To test the hypothesis that higher initial insulin doses would be more efficient during first 48 h of subcutaneous insulin therapy after DKA in cases with new-onset type 1 diabetes.Method: Records of patients ...

Identification of an AR Mutation in Klinefelter’s Syndrome during Evaluation for Penoscrotal Hypospadias

Acar Sezer , Tuhan Hale , Bora Elcin , Demir Korcan , Onay Huseyin , Ercal Derya , Bober Ece , Abaci Ayhan

Background: Klinefelter’s syndrome (KS) is the most prevalent chromosomal abnormality and clinically characterized by oligo-azoospermia, hypergonadotropic hypogonadism, gynecomastia and infertility in adults. Genital malformations in KS have rarely been reported.Objective and hypotheses: To investigate the etiology of penoscrotal hypospadias in a 14-month-old boy.Method: The patient was born from a healthy 23-year-old mother a...

Early-Onset Autoinflammatory Partial Lipodystrophy Characterized by Recurrent Fever and Rash: Candle Syndrome

Demir Korcan , Yildiz Melek , Makay Balahan , Korkmaz Huseyin Anil , Elmas Ozlem Nalbantoglu , Ozkan Behzat

Background: CANDLE (chronic atypical neutrophilic dermatosis with lipodystrophy and elevated temperature) syndrome is a recently described autoinflammatory disease that manifests in early infancy with recurrent fever, violaceous swelling of the eyelids, purpuric skin lesions, hypochromic anemia and elevated acute phase reactants. It is autosomal recessively inherited and associated with partial lipodystrophy, growth retardation and hepatomegaly. PSMB8 (proteasome subu...

Novel Mutation in a Newborn with a Rare Cause of 46,XY Sex Reversal: 17β- Hydroxysteroid Dehydrogenase Type 3 Deficiency

Demir Korcan , Yildiz Melek , Elmas Ozlem Nalbantoglu , Korkmaz Huseyin Anil , Ozkan Behzat

Background: 17β-Hydroxysteroid dehydrogenase type 3 (17β-HSD3) deficiency is a rare cause of 46,XY sex reversal due to a defect in conversion of androstenedione to testosterone. It is autosomal recessively inherited and caused by mutations in 17HSD3.Objective and hypotheses: To define clinical and laboratory characteristics of 17β-HSD3 deficiency during neonatal period.Method: An 8-day-old newborn with female externa...

Genetic Diagnosis Using Whole Exome Analysis in Two Cases with Malign Infantile Osteopetrosis

Demir Korcan , Nalbantoglu Ozlem , Karaer Kadri , Korkmaz Huseyin Anil , Yildiz Melek , Tunc Selma , Ozkan Behzat

Aim: Osteopetrosis is caused by autosomal mutations occurring in nine genes (TNFRSF11A, TNFSF11, TCIRG1, CLCN7, OSTM1, SNX10, PLEKHM1, CA2, and LRP5). Detecting the aetiology and providing genetic counselling via individual mutation analysis of all these genes is expensive and time consuming. Whole exome sequencing is currently increasingly used given that the cost and the time needed are similar to that of single gene sequencing analysis. Here, two newborns,...
