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...

Background: The main purpose of insulin analogue treatment is mimicking physiologic insulin secretion and accomplishing a good glycemic control without having late hypoglycemia in patients with diabetes mellitus.Objective and hypotheses: In this report, 24 weeks follow-up results of newly diagnosed type 1 DM patients treated with insulin lispro and insulin glulisin is discussed.Method: Twelve patients diagnosed with type 1 DM patie...

Background: It’s well known that overt hypothyroidism leads to weight and body fat content increase but there is limited data in the literature about the effect of subclinical hypothyroidism (SH) on body composition parameters.Objective and hypotheses: In our previous study body composition parameters were evaluated in patients with SH and it was concluded that trunk fat mass was increased in SH patients before any alterations in basal metabolism ra...

Introduction: Interstitial deletions on the long arm of the 12th chromosome are rare and often occur de novo. These deletions have been found to be associated with mental retardation, developmental delay, growth retardation and various congenital anomalies in different studies. In studies up to date, it has been determined all interstitial 12q deletions are clustered between five regions on this chromosome (HMGA2, GRIP1, LEMD3, MSRB3, and TMBIM4). Low birth we...

Background: Pycnodysostosis is an autosomal recessive disease characterized by short stature, osteosclerosis, increased bone fragility. In these patients maxillary and mandibular hypoplasia, flattening of the mandibular angle, long soft palate, narrow palate structure can lead to pharyngeal narrowing and obstructive sleep apnea syndrome (OSAS).Objective and hypotheses: Our aim was to evaluate sleep disordered breathing in children with pycnodysostosis.</...

The use of recombinant adeno-associated viruses (rAAV) as safe vectors have allowed hundreds of gene therapy attempts to treat monogenic diseases not including bone genetic diseases (Gao G, Nat Rev Drug Dis 2019). To our knowledge, there has been few attempts to apply gene therapy to monogenic bone diseases, largely because most skeletal malformations are being developed during fetal life. Patients affected with acrodysostosis are known to aggravate their skeletal malformation...

Background: X-linked lissencephaly with ambiguous genitalia (XLAG) syndrome which is a clinical spectrum of ARX mutations is presented with severe growth deficiency, abnormal genitalia and resistant seizures in neonatal period. We present a XLAG case which was formed due to a new ARX mutation and has an appearance of a huge interhemispheric cyst different from classic neuroradiological imagings.Case: The case which was diagnosed with prenatal hydrocephal...

Background: Collodion babies (CBs) are an inherited group of diseases characterized clinically by diffuses severely dry and scaling skin. Patients are generally born prematurely and/or small for gestational age (SGA). Congenital hypothyroidism is seen together with various congenital anomalies, although the mechanism involved is still unclear.Objective and hypotheses: To identify endocrinological problems, and particularly those concerning growth, in 42 ...

Background: The main reason of decrement of growth in children with Prader-Willi Syndrome (PWS) is dysfunction of hypothalamo-hypophseal axis (HHA) and a decrease in the capacity of secretion of growth hormone (GH). In fact, in some cases, GH levels are normal, so there may be other factors in the etiology.Objective and hypotheses: In this study, 19 months old PWS case with growth failure is represented.Method: 13 months old male p...

Background: Phthalates are industrial chemicals extensively used as plasticizers in a variety of commercial products. Di-(2-ethylhexyl) phthalate (DEHP) is one of the most frequently used phthalates. DEHP is readily metabolized to mono-(2-ethylhexyl) phthalate (MEHP), which is more toxic than its parent compound. There are some animal and in vitro studies suggesting that phthalates can disrupt hypothalamus-pituitary-thyroid axis.Objective and hy...
