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: Papillary thyroid cancer (PTC) is the most common endocrine malignancy in children. PTC shows more aggressive progress in children than in adults in respect to local and distant metastases. Here we presented a PTC case with primary pulmonary symptoms and pulmonary metastasis.Case: A 15.5-year-old male patient presented to the clinics with cyanosis and respiratory difficulty for the last 2 years. He had dyspnea, central cyanosis, clubbing, and...

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...
