Background: Irisin is a newly discovered myokine which regulates energy metabolism and obesity (type 2 diabetes pathogenesis). However, results of the clinical studies investigating the relation of irisin with metabolic and anthropometric parameters remain controversial, and studies in obese children are limited.Objective and hypotheses: We aimed to investigate the relation of serum irisin level with metabolic and anthropometric parameters in obese child...

Background: Congenital hypothyroidism (CH) is the most frequent endocrine disorder during neonatal period and delay in diagnosis and treatment leads to irreversible complications. A high L-thyroxine (LT4) dose is recommended for treatment, while the optimal starting dose is still a matter of debate.Objective and hypotheses: The objective of this study was to determine the effects of various starting doses of LT4 on se...

Introduction: Steroidogenic factor-1 (SF1/NR5A1) is a nuclear receptor, which regulates genes that have functions in the development of adrenal glands and gonads, reproduction, and other metabolic functions.Case presentation: A 20-day-old infant was admitted due to ambiguous genitalia. Physical examination revealed a 2×1 cm phallus, bifid scrotum, and hypospadias. Both gonads were palpable in the inguinal canal. Serum levels of adrenal androgens (17...

Background: Androgen insensitivity syndrome is the most common cause of 46,XY disorders of sex development. This condition is inherited in an x-linked recessive pattern and the most common causes are inactivating mutations in the androgen receptor (AR) gene.Objective and hypotheses: In this study, we report a novel AR gene mutation in an adolescent patient presenting with primary amenorrhea.Method: A 16-year-old p...

Background: There exists no gold standard for adjustment of treatment in congenital adrenal hyperplasia. Clinicians try to avoid over-and undertreatment by considering various indicators. We aimed to investigate the sampling times of 17-hydroxyprogesterone (17-OHP) and the use of sex hormone-binding globulin (SHBG) as a monitoring parameter, the association of which was not studied with clinical features. Materials and Methods: This cross-sectional study inclu...

Background: Various studies, mostly conducted in adults, evaluated the hormonal axis in primary empty sella (PES), and reported different forms of pituitary deficiencies. We report our 10-year experience of pediatric cases with PES, investigating the pituitary function, associated impairments, and responses to treatments.Materials and Methods: We reviewed 10,560 cranial and 325 pituitary magnetic resonance imagings (MRIs) performed in ou...

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...

Background: The exact mechanism of the partial clinical remission in type 1 diabetes mellitus (T1DM) has not been elucidated yet. The severity of the inflammation at the time of diagnosis may have an impact on the occurrence or duration of this phase.Objective: We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in children and adolescents with T1DM and the need...

Introduction: Various types of mutations in GHRHR cause isolated growth hormone deficiency type 1B. Here, we report the clinical features associated with deletion of whole GHRHR gene for the first time.Case: A four-year–and-nine-month-old otherwise healthy girl was admitted due to short stature. She was born at term with a birthweight of 3750 gr. Her height velocity slowed down after 2 years of age. The mother (157.8 cm, −0.8...

Introduction: Aromatase deficiency leading to virilization in mother and female fetuses during pregnancy is a rare disease. It is characterized by impaired estrogen production, increased gonadotropins, and ovarian cysts. Herein, we report a clinical phenotype of the virilized female due to a novel compound heterozygous mutation in CYP19A1.Case report: A 4-month-old girl was referred due to cliteromegaly. Her mother had developed acne, hair loss,...
