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...

Younger Age and BMI >3SD are Risk Factors for Mortality in Children with Hypothalamic Obesity

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

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...

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...

Single Gene Variations in Etiology in Children with Severe Obesity

Kahveci Ahmet , Kelestemur Elif , Kurt Ilknur , Guran Tulay , Turan Serap , Bereket Abdullah , Haliloglu Belma

Background: Obesity is a multifactorial disease caused by environmental and genetic factors. Single gene defects explain approximately 5-13% of early-onset obesity and these rates vary according to genetic panel used and the rate of consanguinity in the population studied. As the new treatment modalities emerge for monogenic obesity, it is important to identify the molecular etiology of obesity.Materials and Methods: Buc...

Background: Low-dose adrenocorticotropic hormone stimulation test (LDST) is widely used to assess patients for adrenal insufficiency. However, the predictive power of basal cortisol for the performance of LDST is not clear.Objective: To determine the appropriate basal serum cortisol cutt-off values that predict a positive or negative LDST.Design: A single-centre retrospective study...

Sleep-related Breathing Disorders in Pycnodysostosis

Turan Serap , Atay Zeynep , Gokdemir Yasemin , Bas Nilay , Haliloglu Belma , Abali Saygin , Bas Serpil , Ersu Refika , Bereket Abdullah

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.</...

Severe Hypophosphatemic Rickets due to Tumor-Induced Osteomalasia

Haliloglu Belma , Pehlivan Enes , Yılmaz Duygu , Turan Cift Hakan , Tasdelen Neslihan , Sav Aydın , Alan Selcuk Nalan , Turan Serap ,

Introduction: Hypophosphatemic rickets is usually due to genetic causes but in rare cases it can develop secondary to MAS, Fanconi syndrome, or oncogenic causes. Oncogenic osteomalacia, also called Tumor-Induced Osteomalacia (TIO), is a rare acquired paraneoplastic syndrome that develops as a result of excessive phosphate loss from renal tubules by FGF23 released from tumour tissue. In addition to the clinical features of rickets, gait disturbances, growth ret...

Aim and Method: Diagnosis of type 1 diabetes (T1DM) may be delayed in some children, despite seeking medical care by the family. In this prospective/observational study, the time and process from consulting with a doctor to getting diagnosed with diabetes was investigated in patients hospitalized for newly diagnosed T1DM between 2021-2022.Results: During the study period total of 114 newly diagnosed T1DM patients (49%F, ...

Background: Hepatocyte nuclear factor 1β (HNF1β) is a critical transcription factor that regulates the development of the kidneys, pancreas, liver and genital tract. Patients with deletions and mutations in the HNF1 β gene present with renal and extrarenal manifestations. The most important extrarenal finding is diabetes, also known as MODY5. Although it is generally diagnosed with hyperglycemia, diabetic ketoacidosis is rarely seen.<p class...
