Kirkgoz Tarik , Bas Serpil , Yavas Abali Zehra , Turan Serap , Bereket Abdullah , Guran Tulay

Objective: Antley-Bixler syndrome Type 1 (ABS1) is a rare form of craniosynostosis characterized by multiple dysmorphic features, radio-humeral synostosis and urogenital abnormalities due to P450 oxidoreductase (POR) gene mutations. ABS is also associated with adrenal and gonadal failure which are sometimes underrecognized due to predominance of skeletal findings in various clinics. We report a female patient with very characteristic skeletal and facial features of AB...

Betul Kaygusuz Sare , Atay Zeynep , Kirkgoz Tarik , Guran Tulay , Bereket Abdullah , Turan Serap

Objectives: Spondyloenchondrodysplasia with immune dysregulation (SPENCDI) is an immunoosseous dysplasia combining the typical metaphyseal and vertebral bone lesions with immune dysfunction and neurologic involvement which is caused by mutations in ACP5 gene encoding tartrate resistant acid phosphatase 5. Here, we report a three year old girl presented with primary hypothyroidism, developmental delay and thrombocytopenia and diagnosed as SPENCDI.<p class="abstext"...

Isolated Congenital Central Hypothyroidism due to a Novel Mutation in TSH Beta Subunit Gene

Kirkgoz Tarik , Ozhan Bayram , Cetin Ozan , Kaygusuz Sare Betul , Turan Serap , Bereket Abdullah , Guran Tulay

Objective: Congenital isolated thyrotropin (TSH) deficiency is a rare condition due to autosomal recessive defects in TSHβ, TBL1X, IGSF1, TRHR genes. There are a few patients described with TSHβ mutations to date. These patients display the typical manifestations of severe untreated congenital hypothyroidism. Most patients are unrecognized, even in newborns screening settings due to unelevated TSH levels, which results in severe growth fail...

Precocious Puberty in Patients with Primary Adrenal Insufficiency due to Melanocortın Receptor 2 Mutation

Bas Firdevs , Abali Zehra Yavas , Guran Tulay , Genens Mikayir , Poyrazoglu Sukran , Bundak Ruveyde , Darendeliler Feyza

Background: Precocious puberty has a complex and polygenic etiology. To describe genetic factors affecting onset and regulation of puberty and pathophysiology of precocious puberty, further studies are needed. Although, it is reported that ACTH receptor MC4R has impact on premature adrenarche, MC2R is expressed in the adrenal cortex and has a major role on the control of hypothalamo-pituitary-adrenal cortex. Melanocortin signaling system is reported to have l...

β-hCG from an Occult Source Causing Peripheral Precocious Puberty: Identification of the Tumour 6 Years After Presentation

Ekberzade Azad , Abali Saygin , Atay Zeynep , Bas Serpil , Gurbanov Ziya , Turan Serap , Guran Tulay , Bereket Abdullah

Background: β-hCG secreting germ-cell tumors (β-hCG-ST) are rare causes of Peripheral precocious puberty (PPP) in boys and usually located in intracranial region. Liver, retroperitoneum, testis and mediastinal cavity are the other localizations reflecting embryonic germ cell sites.Objective and hypotheses: We present a patient with PPP due to elevated β-hCG levels, but extensive efforts to find the source of elevated β-hCG was unrevea...

Eleven Years of Letrozole Treatment in a Child with 11-β Hydroxylase Deficiency: Effect on Bone Age and Height Prognosis

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

Background: Aromatase inhibitors (AI) are being used in clinical trials in children related to peripheral precocious puberty, and idiopathic short stature to improve height prognosis.Case report: A 2 11/12 year-old boy was referred to our center for evaluation of penile enlargement and pubic hair development. Physical examination revealed a well-developed muscular boy with a body weight of 22 kg (>97p), height of 110.1 cm (>97p), with ...

Hyperthyroidism Due to TSH Secreting Pituitary Adenoma in a 7-Year-Old Boy

Abali Saygin , Atay Zeynep , Haliloglu Belma , Guran Tulay , Bereket Abdullah , Turan Serap

Background: Pituitary adenomas in childhood are 2–6% of all surgically treated pituitary adenomas at all ages. It has been estimated that TSH secretion is rare (<1% of all pituitary adenomas). Therefore, TSH secreting adenoma is very rare in childhood. Here we present the youngest patient with TSH secreting adenoma.Case: A 7-year-old boy was referred to our clinic with thyroid dysfunction by the psychiatry clinic, during his evaluation of hypera...

Background: Hypothalamic obesity is the most flagitious endocrinologic problem following surgical intervention for childhood brain tumors. Thus, recognition of this condition and identification of risk factors for mortality is important.Objective and hypotheses: In this study, we have shared our single center experience in obesity-related mortality in children with hypothalamic obesity.Method: We retrospectively analyzed 20 patient...

Background: Studies evaluating the gain in final height in patients with idiopathic central precocious puberty (ICPP) report variable outcomes and mostly lack comparison with untreated controls.Objective and hypotheses: To compare the final height of ICPP patients treated with GnRH analog with and untreated control group.Method: 48 girls with ICPP treated with GnRH analog and 52 untreated girls with ICCP (due to late referral or re...

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...
