Guven Raziye Burcu , Ozen Samim , Gokşen Damla , Korkmaz Ozlem , Darcan Şukran

Introduction: Studies show that onset of puberty in girls is occurring at increasingly younger ages. Environmental endocrine disruptors are implicated in the etiology of early puberty. Polychlorobiphenyls (PCBs) are one of the endocrine disruptor with proven estrogenic effects.Aim: To investigate the effect of PCBs on premature puberty in girls.Materials-Methods: The study group was selected from girls aged 2–8 years with a di...

Does Acquired Hypothyroidism Lead to Precocious Puberty?

Aydın Dilek , İşguven Pınar , Aydın Engin

Introduction: Hypothyroidism without treatment usually leads to delayed puberty in pediatric patients, sometimes it may rarely lead Van Wyk Grumbach syndrome (VWGS) which is characterized by isosexual precocious puberty. Exact mechanism of VWSG is unknown. High thyroid stimulating hormone (TSH) levels may directly effect on follicular stimulating hormone (FSH) receptors and lead precocious puberty. Interestingly simple thyroid hormone replacement therapy resolves symptoms in t...

Introduction: Alström syndrome is a rare autosomal recessive disorder characterized by type 2 diabetes, early-onset obesity, hypogonadism, dyslipidemia, progressive retinal degeneration, sensorineural hearing loss, cardiomyopathy and renal failure.Case Report 1: A 13 years-old girl consulted because of high blood glucose (442 mg/dl). HbA1c was 8.9%, C-peptide was 4.5 g/dl, insulin was 17.5 μU/ml, insulin antibodies were negative. The parents we...

Transient Neonatal Diabetes Mellitus: New Case

Hancili Suna , Guven Ayla , Akin Ilke Mungan , Cebeci Ayse Nurcan , Edwards Sian

Introduction: Neonatal diabetes mellitus (NDM) is a monogenic form of diabetes that occurs in the first 6 months of age. It is a rare condition occurring in only one in 100 000–300 000 live births. Clinically, NDM subgroups include transient (TNDM) and permanent NDM (PNDM). TNDM is most frequently caused by abnormalities in the imprinted region of chromosome 6q24.Case Report: A 18-day-old male was referred from another clinic due to diabetic ketoaci...

A Case of Transverse Testicular Ectopia with Persistant Müllerian Duct Syndrome: A Novel AMH Gene Mutation

Kılınc Suna , Cicek Tuğrul , Moralıoğlu Serdar , Guven Ayla

Background: The concurrence of transverse testicular ectopia (TTE) with persistent müllerian duct syndrome (PMDS) is extremely rare. Here, we report a case of TTE with PMDS in a 7-month-old male infant presenting with inguinal hernia and a novel homozygous mutation in the AMH gene. CASE REPORT: A 7-month-old male infant presented to pediatric surgery department with an inguinal hernia on the left side and bilateral undescended testis. During left herniotomy, tiss...

Background: Disorders of sex development (DSD) vary phenotypically and are caused by a number of genetic etiologies. Although several genetic abnormalities have been discovered through genetic analyses, the underlying genetic causes of 46, XY DSD remain unknown in most of the casesAim: To identify genetic defects in patients with 46,XY DSD.Material and Methods: A total 76 DSD patie...

Introduction: Congenital adrenal hyperplasia (CAH) is an autosomal recessively transmitted disease and 95% of CAH cases are due to 21-hydroxylase deficiency (21-OHD). There are more than 100 mutations that cause CAH due to 21-OHD and the clinical expression of the disease is reported to correlate with mutated alleles.The aim: The aim of this study was to investigate responsible mutations and then to evaluate genotype...
