Suboptimal head growth in utero and in early neonatal life may affect linear growth and weight gain during infancy. We studied linear growth and weight gain of 56 preterms (GA = 33.5 +/- 2.2 weeks) with birth weight >1.5 < 2.5 kg) for two years. They were classified at birth into two groups (group 1 with HCZ <-1) (relatively small head for GA) (35 +/- 2 weeks) and group 2 with HCZ > -1 (GA = 33 +/- 1.7 weeks)Results: Preterm ...

Oculocerebrorenal syndrome of Lowe (OCRL) is an X-linked and multisystem disorder with clinical symptoms of congenital cataracts, severe mental retardation, hypotonia, areflexia, and incomplete Fanconi syndrome of the proximal renal tubules. We report a 15-year-old short stature male with a severe form of OCRL syndrome, diagnosed based on bilateral congenital cataract, proteinuria, tubulopathy, and dysmorphic findings. The physical examination revealed a height of 152 cm (-2.7...

Kırkgöz Tarık , Ozkan Behzat , Acar Sezer , Hazan Filiz , Ikegawa Shiro , Guo Long

Dysosteosclerosis (DOS) is a rare form of dense bone disease and, short stature, recurrent fractures, optic atrophy, cranial nerve palsy, developmental delay, flattened fingernails, skin related complications, and failure of tooth eruption are the characteristic features of the disease (MIM %224300). Irregular osteosclerosis, flattened diffusely dense vertebral bodies, sclerotic skull, radiolucent sub-metaphyseal portions of the long tubular bones with sclerotic diaphysis are ...

Improvement of Final Height in Idiopathic Central Precocious Puberty is Associated with Delay of Bone Maturation with GnRH Agonist Therapy Under the Age of 7 Years

Vuralli Dogus , Gonc E. Nazli , Ozon Z. Alev , Kandemir Nurgun , Alikasifoglu Ayfer

Background: GnRHa therapy is shown to be beneficial in increasing final height when started before 6 years of age in girls with idiopathic CPP(iCPP). However controversial data exist in improvement of final height whose pubertal signs appear after age of 6.Aim: To investigate effect of age of onset of GnRHa therapy on final height n girls with iCPP, and to evaluate factors affecting height gain.<st...

Long Term Effects of GnRH Agonist Therapy on BMI in Girls with Idiopathic Central Precocious Puberty

Vuralli Dogus , Ozon Z. Alev , Gonc E. Nazli , Alikasifoglu Ayfer , Kandemir Nurgun

Background: Studies investigating effects of GnRHa therapy on body weight (BW) and BMI in subjects with CPP are generally including short term effects.Aim: To investigate changes in BMI at the beginning, during and two years after completion of GnRHa therapy to determine influential factors in girls with idiopathic CPP.Methods: Data of 138 girls who completed GnRHa therapy for iCPP...

To Whom Should Central Nervous System Imaging be Performed in Girls with Central Precocious Puberty (CPP)?

Vuralli Dogus , Gonc E. Nazli , Alikasifoglu Ayfer , Kandemir Nurgun , Ozon Z. Alev

Background: Organic lesions are present in 5-10% of cases with CPP. Determinants of an increased risk for organic pathology underlying CPP in girls are debatable. CNS imaging is recommended for girls who have pubertal signs before 6 years of age. Although neurological findings may suggest organic pathology, other clinical features and hormonal variables have not been adequately examined.Aim: To analyze clinical&h...

A Novel Inactivating Compound Heterozygous Mutation in KISS1R/GPR54: Cases of Three Siblings

Nalbantoglu Ozlem , Arslan Gulcin , Koprulu Ozge , Hazan Fılız , Gursoy Semra , Ozkan Behzat

Introduction: Kisspeptin is a neuropeptide, encoded by the KISS1 gene, which acts upstream of gonadotropin-releasing hormone (GnRH) neurons and also has a critical role for maturation and function of the reproductive axis. Inactivating mutations of its receptor (KISS1R) cause normosmic isolated hypogonadotropic hypogonadism (IHH). In this report, we aim to present three siblings who have IHH due to novel compound heterozygous KISS1R mutation.Cas...

GH Deficiency in a Case with Neurofibromatosis-Noonan Syndrome

Vuralli Dogus , Gonc E Nazli , Vidaud Dominique , Ozon Z Alev , Alikasifoglu Ayfer , Kandemir Nurgun

Background: Neurofibromatosis-Noonan Syndrome (NFNS) is a distinct entity which has variable features of both neurofibromatosis 1 (NF1) and Noonan syndrome (NS). In majority of cases NF1 mutations have been demonstrated. Short stature is one of the major causes for these patients requiring medical attention. GH deficiency (GHD) may accompany in some cases with NF1 or NS cases, however there are rare case reports on NFNS receiving GH therapy.Objective and...

Severe Undervirilisation in a 46,XY Case due to a Novel Mutation in HSD17B3 Gene

Alikasifoglu Ayfer , Vuralli Dogus , Hiort Olaf , Gonc E Nazli , Ozon Z Alev , Kandemir Nurgun

Background: 17-β-hydroxysteroid dehydrogenase 3 (17-β-HSD3) deficiency is a rare disorder of sex development due to impaired conversion of androstenedione to testosterone. Children with 46,XY karyotype often have female appearing external or ambiguous genitalia at birth. At the time of puberty, virilisation can occur. Therefore 46,XY patients with HSD17B3 gene defects should be raised as male.Objective and hypotheses: When a child with 46,XY ka...

Long Term Effects of Bisphosphonate Treatment in a Case with Infantile Onset Severe form of Juvenile Paget’s Disease

Gonc E Nazli , Ozon Z Alev , Buyukyilmaz Gonul , Alikasifoglu Ayfer , Simsek Ozlem , Kandemir Nurgun

Background: Juvenile Paget’s disease is a rare autosomal recessive osteopathy. Patients presenting in infancy develop severe bone deformities and may never walk. Bisphosphonate therapy is used to decrease bone turnover and it has generally good responses in milder forms of the disease. However there is no long-term experience of bisphosphonates in severe infantile forms.Case report: A 9 month-old boy was referred to our clinic for bone deformities. ...
