A Practical and Integrative Approach to Differential Diagnosis Between Precocious Puberty and Premature Telarch: Newly Proposed Clinical and Laboratory Finding-Based Diagnostic Scoring in Precocious Puberty and Premature Telarch

Karaoglan Murat , Keskin Mehmet , Ozkur Ayhan , Keskin Ozlem

Background: Accurate and differential diagnosis of preococious puberty (PP) have some important challenges. Many parameters have used to diagnose pubertal diseases so far. However LH-RH stimulation test is considered as a gold standard procedure, ıt has some difficulties in practise.Objective: We aimed to set a newly proposed clinical and laboratory finding-based diagnostic scoring in the differential diagnosis of preoccious puberty and premature te...

Keskin Mehmet , Karaoglan Murat , Demir Korcan , Keskin Ozlem

Introduction: GnRH analogues common used in precocious puberty are highly effective agents. The drug dose and injection frequency should be designed for each case. However these agents are common well tolerated, some rare adverse effects may be occur. We present a case of frequent leuprolid acetate injections-related sterile abscess.Case: The case was 16-month-old boy. He had rapid growth, big penis, and excessive pubic hair. These symptoms have appeared...

Objective: There have no been studies enough about thyroid volumes of obese and adolescent children. In this study, we purposed comparing of thyroid volumes in respect of anthropometric, biochemical, metabolic parameters in following groups: Overweight, obese, morbid obese, and healthy children.Method: Two groups were compared: The first group consisted of 190 children whose BMIs are above the 85th percentile. The second group was 90 children with normal...

A Novel Approach for the Evaluation of Hypothalamic-Pituitary Region in Patients with Growth Hormone Deficiency: Pons Ratio

Demiral Meliha , Karaca Mehmet Salih , Unal Edip , Baysal Birsen , Baran Riza Taner , Demirbilek Huseyin , Ozbek Mehmet Nuri

Objective: In patients with growth hormone deficiency (GHD), even in those with no major organic lesion, anterior pituitary height (APH) is reported decreased. Limitations in the evaluation of APH and changes according to pubertal status make its validity questionable. Recently, in a small scale study, pons ratio (PR) has been suggested as a more sensitive marker for evaluation of pituitary gland in GHD patients. The study aims to evaluate the validity of PR a...

Objective: Congenital Hyperinsulinism(CHI) is a clinically, genetically, and histologically heterogeneous disease. Turkey is a county with highly prevalent cases of severe CHI due to the high rate of consanguinity and recessively inherited KATP gene mutations. We herein evaluated the clinical characteristics, molecular genetic analysis, and follow-up of a large nationwide cohort of CHI from Turkey.Patients and method: Th...

Background: Cytochrome P450 oxidoreductase (POR) deficiency (PORD) is a form of congenital adrenal hyperplasia (CAH) and results in steroid-production loss from cytochrome P450 proteins. Mutations in POR cause mild to severe forms of CAH with/without bone malformation symptoms resembling Antley-Bixler syndrome. We report a novel POR Arg550Trp mutation identified in a 46,XX patient with signs of aromatase (ARO) deficiency. Child (first pregnancy) and mother pr...

The Relationship between Visceral Adipose Index and Metabolic Syndrome in Children with Type 1 Diabetes Mellitus

Albayrak Serpil , Karaoglan Murat , Keskin Mehmet , Yıldırım Ahmet

Background/Aim: Prediction of metabolic syndrome (Mets) plays important role in cardiovascular disease risk prevention. Although Mets is relatively common in children with T1DM, diagnosis and prediction are ignored. Visceral Adiposity Index VAI) has been defined as a new cardiometabolic risk marker reflecting abdominal fat distribution and dyslipidemia. The aim of the study is to reveal the relationship between Mets and components of VAI in patients with T1DM....

Donohue syndrome in a Turkish infant: Mild clinical course despite severe genetic mutation

Tepe Derya , Kocaay Pinar , Cakir Gundogan Secil , Sirma Dokuzboy Refika , Boyraz Mehmet

Donohue syndrome(DS) is a rare and often lethal autosomal recessive disease. Its prevalence is estimated less than one in a million live births. Mutations in the insulin reseptor (INSR) gene cause rare severe INSR-related insulin resistance syndromes such as DS. It is characterized by severe insulin resistance (hyperinsulinemia, fasting hypoglycemia and postprandial hyperglycemia), intrauterine and postnatal growth retardation, hypotonia, organomegaly including heart, liver, k...
