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: 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...

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...

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.</...

Evaluation of Basal and GNRH-stimulated AMH Levels in Central Precocious Puberty, Peripheral Precocious Puberty and Premature Thelarche

Sahin Nursel Muratoglu , Yilmaz Aslihan Arasli , Erdeve Senay Savas , Cetinkaya Semra , Aycan Zehra

Objective: AMH decreases by 30% in the first two years following puberty. Although it is known that AMH is associated with FSH and LH, the AMH response to rapid changes in GnRH is not known clearly in puberty. It has been shown that AMH levels in central precocious puberty (CPP) are lower than in premature thelarche (PT), but the levels of AMH in peripheral precocious puberty (PPP) have not been evaluated. The aim of this study was to evaluate the basal an...

A Case of Prohormone Convertase Deficiency Diagnosed with Type 2 Diabetes Mellitus

Kucukali Gulin Karacan , Savas-Erdeve Senay , Cetinkaya Semra , Keskin Meliksah , Bulus Ayse Derya , Aycan Zehra

Background: Prohormone convertase is an enzyme that converts many biologically inactive prohormones into biologically active peptides. Its deficiency is characterized by deficiency of variable levels in all the hormone systems. In relation to this, postprandial hypoglycemia has been reported but, a case of prohormone convertase deficiency presenting with a diagnosis Type 2 diabetes mellitus has not been previously reported.Case p...

Different Endocrine Affects in DICER-1 Syndrome

Yilmaz Aslihan Arasli , Aycan Zehra , Erdeve Senay Savas , Çetinkaya Semra

Introduction: DICER1 syndrome is a pleotropic, autosomal dominant familial genetic tumor predisposition syndrome. DICER1 somatic + germ-line mutations (double hit hypothesis); cystic nephroma; pleuropulmonerblastoma, ovarian sex cord-stromal tumors, multinodular goitre (MNG) are associated with many conditions such as differentiated thyroid cancer, pituitary blastoma. We presented three cases, two of whom were siblings, who had been consulted because of no...

Evaluation of Clinical, Laboratory and Therapeutic Features and Long Term Follow-up Results in 44 Cases with Genetic Diagnosis of MODY; Single Center Experience

Ozalkak Servan , Keskin Meliksah , Çetinkaya Semra , Erdeve Senay Savas , Bayramoglu Elvan , Aycan Zehra

Introduction-Aim: MODY;It is an autosomal dominant, rare type of diabetes that occurs in young people as a result of mutations of beta cell function and genes involved in insulin secretion. The cases may be misdiagnosed as Type1 and Type2 diabetes. Considering that MODY is clinically and genetically heterogeneous, the findings should be evaluated correctly. It is important to define the clinical-laboratory characteristics of diagnosis and follow-up of patients...

Can Increased First Hour Glucose Concentration in OGTT Be a New Indicator in Projecting Metabolic Profile?

Sahin Nursel Muratoglu , Yilmaz Aslihan Arasli , Özalkak Servan , Aycan Zehra

Aim: Recent studies have shown that the first hour glucose concentration of ≥155 mg / dL in the oral glucose tolerance test (OGTT) in adults with normal glucose tolerance (NGT) may be a strong marker for the development of diabetes, and also an increase in subclinical inflammation, insulin resistance, dyslipidemia and serum transaminases. These results indicate that adults with NGT have increased risk of developing cardiovascular disease and non-alcoholi...

Evaluation of Diagnosis, Follow-up and Treatment Results of Growth Hormone in Rare Diseases; 10 Year Single Center Experience

Aycan Zehra , Arasli Yilmaz Aslihan , Yel Servet , Savas Erdeve Senay , Çetinkaya Semra

Introduction: Growth hormone therapy (GHT); have been used in rare diseases such as growth hormone deficiency (GHD), panhipopituitarism (PHP), intrauterine growth retardation (IUGR), Turner Syndrome(TS) for many years while the effects of diagnostic timing on the treatment results are known. However,data on the diagnosis and treatment processes of these diseases are limited in our country. The aim of this study was to evaluate the results of diagnosis, follow-...
