Final adult height and bone mineral density of the children who were treated with gonadotropin releasing hormone analogues near the age eight

Bahar Semra , Tolga Ozgen Ilker

Aim: Central precocious puberty (CPP) is defined as premature activation of the hypothalamic–pituitary–gonadal (HPG) axis before the age 8 in girls. Precocious puberty starting at a very young age causes a severe loss in height potential and should be treated with gonadotropin releasing hormone agonists (GnRHa). However, there are controversial results about the benefit of the GnRHa treatment in girls whose CPP is initiated near the age 8. This stu...

Effects of Inhaled Corticosteroids and Montelukast on Growth and BMI in Children with Asthma

Akin Onur , Yavuz Suleyman Tolga

Background: Inhaled corticosteroids (ICS) and montelukast are commonly prescribed drugs in asthma treatment. Several studies have investigated the adverse effects of ICS on growth and weight gain in children. However, the biosafety studies of montelukast are mostly focused on the neuropsychiatric side effects. The present study aimed at investigating the adverse effects of montelukast and ICS on anthropometric parameters in children.Methods: The present ...

A case report of hyperinsulinemic hypoglycemia caused by a heterozygous novel mutation in the insulin receptor gene

Tolga Ozgen Ilker , Bahar Semra , Uyanik Bulent

Introduction: Mutations in the insulin receptor (INSR) gene usually progress with insulin resistance and hyperglycemia. However, rare heterozygous INSR gene mutations that cause hyperinsulinemic hypoglycemia (HH) have also been described. A case with hyperinsulinemic hypoglycemia due to a new variant mutation in the INSR gene, is presented.Case: A 13-month-old male patient was referred to us with complaints of contractio...

A case report of Pituitary Stalk Interruption Syndrome caused by novel compound heterozygous mutations in the KATNIP gene

Bahar Semra , Tolga Ozgen Ilker , Uyanik Bulent

Introduction: Pituitary stem interruption syndrome (PSIS) is a congenital anomaly of the pituitary gland characterized by the absence or thinness of the pituitary stalk, an ectopic posterior pituitary gland and a hypoplastic or aplastic anterior pituitary gland. Our case is an example of this rare syndrome.Case: A 12-month-old male patient was referred to us by pediatric urology for micropenis and undescended testis. He ...

A case of diabetes and deafness with heteroplasmic mutations in the mitochondrial DNT1 gene

Tolga Ozgen Ilker , Bahar Semra , Uyanik Bulent

Introduction: Diabetes mellitus can develop as a result different etiology. Mitochondrial diseases may also cause diabetes mellitus. However, mitochondrial mutations are generally thought to be accompanied by a severe clinical finding. We present a patient who is determined 80% heteroplasmic deletion in the MT-DNT1 gene, with hearing loss and mitochondrial diabetes, which is quite different from the classical phenotype.Case:</str...

A novel heterozygous STAT5B variant in a patient with resistant atopic dermatitis and short stature.

Bahar Semra , Tolga Ozgen Ilker , Uyanık Bulent

Introduction: Growth hormone (GH) exerts its effect through insulin-like growth factor 1 (IGF-I), an intracellular signalling molecule whose production is stimulated by STAT-5b after binding to the growth hormone receptor. STAT-5b deficiency, is characterized by short stature, immune dysregulation and chronic lung disease. And these occur as a result of disruption of the growth hormone axis. Our case is an example of STAT-5b gene mutation, which is a rare dise...

Renal Involvement ın Obese Children and Adolescents

Kaya Mehmet Sirin , Anık Ahmet , Unuvar Tolga , Sonmez Ferah

Background and aim: Epidemiologic studies have been shown that obesity increases the risk of renal disease and it impact on prognosis. In this study, we aimed to investigate both glomerular and tubular involvement in asymptomatic obese children and to investigate the association of metabolic-anthropometric parameters with renal parameters.Material-method: Children with BMI ≥95th percentile and diagnosed as primary obesity (n=43) were inclu...

An Unusual form of Precocious Puberty: Van Wyk and Grumbach Syndrome

Anık Ahmet , Avcı Esma Cigdem , Unuvar Tolga

Introduction: The association of precocious puberty and/or polycystic ovaries, delayed bone age and hypothyroidism is known as the Van Wyk and Grumbach syndrome (VWGS). Clinically this syndrome is a diagnostic challenge because hypothyroidism usually leads to pubertal and growth delay, whereas in case of VWGS hypothyroidism it leads to growth delay and precocious puberty. We report a boy with long-standing, untreated hypothyroidism who presented with precocious puberty.<p ...

45,X/47,XYY Chromosomal Mosaicism as a Cause of 46,XY Disorder of Sex Development

Anik Ahmet , Kasikci Esma Tugba , Sahin Suzan , Unuvar Tolga , Turkmen Munevver Kaynak

45,X/47,XYY mosaicism is quite rare, and, like 45,X/46,XY, it can be associated with mixed gonadal dysgenesis, Turner syndrome or apparently normal male/female phenotype. An infant aged 16 days, born full-term via spontaneous vaginal delivery to a 32 year-old G1P1 woman. His pregnancy and perinatal period were both uncomplicated except for maternal long QT syndrome. There was third degree cousin consanguinity between the parents. There was no any virilizing drug use and no mat...

Endocrinological Assessment of Children with Bronchiectasis

Ozgen Ilker Tolga , Cakir Erkan , Gedik Hakan , Gokce Selim , Atilla Nursoy Mustafa , Cesur Yasar

Background: Bronchiectasis is a result of recurrent pulmonary infections and chronic inflammation.Objective and hypotheses: Chronic inflammation may lead some endocrinological disorders. The consequences of the bronchiectasis on the endocrinological system and on the bone health in childhood were investigated in this study.Method: The medical records of the 64 children with bronchiectasis (32 females and 32 males) at the mean age o...
