A Rare Cause of Congenital Adrenal Hyperplasia due to P450 Oxidoreductase Deficiency: a Case Report

Cinaz Peyami , Cihan Emeksiz Hamdi , Celik Nurullah , Doger Esra , Yuce Ozge , Camurdan Orhun , Bideci Aysun

Background: P450 oxidoreductase (POR) deficiency is the newest form of congenital adrenal hyperplasia first described in 2004. POR is a protein that transfers electrons from NADPH to all 50 microsomal forms of cytochrome P450. Mutations that cause POR deficiency result in partial deficiency of the enzymes 21-hydroxylase and 17α-hydroxylase. Remarkable clinical features of the POR deficiency are genital ambiguity in both sexes, glucocorticoid deficiency and Antley-Bixler s...

Evaluation of Final Height in Girls Taking GnRH Analogue: Should the Age Limit for Precocious Puberty be Changed?

Vuralli Dogus , Dallar Yildiz Bilge , Tapci Esra , Engiz Ozlem , Simsek Enver

Background: The age limit for precocious puberty (PP) in girls is a topic that continues to be debated, and there is a new trend that supports the idea that the beginning of breast development in girls between ages 6 and 8 should not be accepted as true PP and it is necessary to label this clinical condition as accelerated puberty or early normal puberty.Objective and hypotheses: The aim of the current study is to determine the diagnostic criteria for gi...

Stevens Johnson Syndrome in a Case with Type 1 Diabetes Mellitus: Relation or Coincidence?

Akin Onur , Doger Esra , Demet Akbas Emine , Bakirtas Arzu , Camurdan Orhun , Bideci Aysun , Cinaz Peyami

Background: Stevens-Johnson syndrome (SJS) is an acute life-threatening dermatosis characterised 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 recurr...

Background: Hereditary 1,25-dihydroxyvitamin D resistant rickets (HVDRR) caused by vitamin D defective receptor.Objective and hypotheses: We performed VDR gene analysis four patients with alopecia, skeletal dysplasia, and hypocalcaemia.Method: Genomic DNA extracted from peripheric blood. Whole gene sequence analysis was performed.Results: We found homozigot p.Q152* (c.454G>T) mutation three patients. Two ...

Natural History of LEP, LEPR and MC4R Deficiencies – A Population-Based Study

Saeed Sadia , Manzoor Jaida , Khanam Roohia , Janjua Qasim , Ning Lijiao , Ayesha Hina , Khan Waqas , Bonnefond Amélie , Hanook Sharoon , Butt Taeed , Arslan Muhammad , Froguel Philippe

Background: Proteins encoded by LEP, LEPR and MC4R genes are principally involved in driving the leptin-melanocortin pathway. Mutations in these genes induce a rare and severe form of monogenic obesity but the long-term evolution of these afflictions is unknown. Here, we carried out a clinical investigation on 132 children with LEP, LEPR and MC4R deficiency from Pakistan to evaluate progression of the disease and its impact on co-mor...

Serum Level of Biotin Rather than the Daily Dose is the Main Determinant of the Interference on Thyroid Function Assays in Patients with Biotinidase Deficiency

Paketci Ahu , Kose Engin , Calan Ozlem Gursoy , Acar Sezer , Teke Pelin , Demirci Ferhat , Abacı Ayhan , Demir Korcan , Arslan Nur , Bober Ece

Introduction: High doses of biotin are reported to cause incorrect results in various immunoassays in some patients. However, there is no systematic study regarding biotin interference in childhood.Aim: To assess thyroid function with different methods in subjects with biotinidase deficiency, to determine the factors causing interference, and to investigate the efficiency of the methods for overcoming interference.Method: The study...

"Steroidogenic Factor-1" (SF-1); It is encoded by the NR5A1 gene in 9q 33.3 and regulates the transcription of genes involved in steroidogenesis. It is reported that 46 of the variants in this gene constitute 10-20% of XY sex development disorders (DSD). The patient admitted because of a swelling in the left groin at one month old. She was raised as female. Uterus was 12x2.5 mm in ultrasonography and the gonad in the inguinal region was evaluated as testis. She was P...
