Bas Serpil , Abali Saygin , Atay Zeynep , Gurbanov Ziya , Turkdogan Dilsad , Turan Serap , Bereket Abdullah

Background: Friedreich’s ataxia (FA) is an autosomal recessive neurodegenerative disorder characterised by progressive ataxia with limb muscle weakness, absent lower limb reflexes, extensor plantar responses, dysarthria, decreased vibratory sense and proprioception. The most common molecular abnormality is a GAA trinucleotide repeat expansion in intron 1 of the frataxin (FXN) gene. Patients with FA are at risk of getting increased blood sugar levels, or ...

Central or Primary Hypothyroidism? How to Differentiate in Patients with Low T4 but Mildly Elevated TSH Levels

Turan Serap , Gurbanov Ziya , Bas Serpil , Abali Saygin , Atay Zeynep , Bereket Abdullah

Background: Central hypothyroidism (CH) is caused by TSH and/or TRH deficiency leading to hypothyroxinemia with low, normal or mildly elevated TSH levels. Differentiation of CH with mildly elevated TSH levels from primary hypothyroidism (PH) can be difficult. However, this differentiation has important clinical implications (i.e. cortisol replacement before L-thyroxine).Objective and hypotheses: In this study, we constructed a nomogram all...

Background: Klinefelter syndrome, also known as 47, XXY, is a disorder characterized by tall stature, hypogonadism and mental retardation which is caused by nondisjunction events during meiosis and occurs in 500–1 000 live male birth. Here we report a patient with Klinefelter syndrome who presented with short stature, in contrast to common tall stature presentation and was diagnosed with GH deficiency.Case: A 7-year-old male presented with short sta...

Genens Mikayir , Poyrazoglu Sukran , Sukur Mine , Bas Firdevs , Bundak Ruveyde , Darendeliler Feyza

Background: Compliance of patients on GH treatment is very important for the success of the treatment. In a multıcentre study done in Turkey we had shown that compliance decreased at the end of 1st year of treatment which had an adverse effect on growth rate and IGF1 levels.Objective and hypotheses: To evaluate whether doing regular questionnaire to patients on GH has an effect on compliance at long term.Method: A questionnair...

Evaluating First Year Response and Final Height to Growth Hormone Treatment in Growth Hormone Deficiency Based on Peak GH Levels on Testing

Abali Saygin , Bas Serpil , Akbarzade Azad , Atay Zeynep , Haliloglu Belma , Guran Tulay , Turan Serap , Bereket Abdullah

Background: Diagnosis of GH deficiency (GHD) is a complicated issue especially in isolated GH deficiency. Auxological evaluation, IGFI, IGFBP3 levels and GH response to provocative testing are all considered in the diagnosis. However, cut-off values for GH levels at stimulation tests are controversial. We aimed to evaluate the response to rhGH treatment in patients with different GH peak levels in stimulation test.Objective: We aimed to evaluate the resp...

Factors Effecting Response to Growth Hormone Treatment in Children with Turner Syndrome

Bas Serpil , Abali Saygin , Atay Zeynep , Haliloglu Belma , Gurbanov Ziya , Guran Tulay , Bereket Abdullah , Turan Serap

Background: Short stature is the most common presenting symptom in Turner Syndrome (TS). GH treatment helps alleviating short stature in TS, although response to treatment varies significantly.Objective and hypotheses: We aimed to evaluate the response to GH treatment and factors affecting this response in children with TS.Method: Forty-nine patients with TS diagnosed by cytogenetic analysis and who had been followed minimum of 1-y...

Phenotypic Characteristics of Patients with 45,X/46,XY Mosaicism: Growth, Gonadal Pathology and Tumour Risk

Poyrazoglu Sukran , Bas Firdevs , Karaman Birsen , Yildiz Melek , Basaran Seher , Darendeliler Feyza ,

Background: The 45,X/46,XY mosaicism represents a wide spectrum of phenotypes, from phenotypically normal females to males and varying degrees of genital ambiguity. Growth seems to be impaired in these patients. It is associated with increased risk of germ cell tumours.Aim: To evaluate growth, gonadal function and tumour risk in a large group of children with 45,X/46,XY mosaicism in a single tertiary centre.<p class=...

Evaluation of early puberty in boys and girls with Silver-Russell Syndrome: Discordance between testicular growth and pituitary-gonadal hormones in male cases

Yildiz Melek , Bas Firdevs , Karaman Birsen , Poyrazoglu Sukran , Basaran Seher , Darendeliler Feyza ,

Background: In Silver-Russell Syndrome (SRS), it is known that puberty starts early, frequency of premature adrenarche increases and adrenarche progresses aggressively. However, data regarding gonadal functions and testicular development in males during pubertal period is still insufficient.Methods: Twenty-four cases (9F, 15M) who were followed-up with diagnosis of SRS between 1990-2020 were included in the study. The di...

Background: Approximately one-third of the central precocious puberty (CPP) cases have familial transitions. Although more than 30 genes related to puberty have been reported to date, only a few (KISS1, KISS1R, MKRN3, DLK1 and PROKR2) were associated with CPP. This study aims to reveal the associated sequence variants of MKRN3 and DLK1 genes in cases with familial CPP and their etiology.Method:...
