Iodine is the most important element in thyroid function. Its deficiency and excess can cause hypothyroidism. Our location has been known as the iodine deficiency area for the last 20 years. In this study, we aimed to investigate thyroid dysfunction and assess its relationship with iodine levels in the neonatal period.Method: One hundred and seventy newborns were included in the study. Infants were selected from patients referred to for ...

Background: Adrenocortical tumors in childhood represent very rare about 0.2% of all pediatric malignancies. Cushing’s syndrome (CS) is characterized by clinical features caused by autonomous excessive glucocorticoid production from adrenal cortex. In ACTH-independent CS, the most common cause is unilateral cortisol-producing adrenocortical adenoma.Objective and hypotheses: Fifteen months old girl was admitted with gradually gain weight, pubarche, a...

Background: Hypophosphatasia (HPP) is a rare metabolic bone disease caused by loss-of-function mutations in the gene ALPL encoding the tissue nonspecific alkaline phosphatase. HPP is associated with significant morbidity and mortality in pediatric patients, with high rates as high as %100 in perinatal-onset HPP. Serum alkaline phosphatase (ALP) activity is markedly reduced, which leads to increased serum/urine phosphoethanolamine (PEA), pyridoxal-5’phosphate (PLP). Asfota...

Background: Idiopathic intracranial hypertension (IIH) is a disorder of elevated intracranial pressure without any evidence of intracranial pathology or underlying systemic disease. Obesity was reported as a significant cause of IIH in childhood especially in adolescents.Objective and hypotheses: IIH is a disorder of elevated intracranial pressure without any evidence of intracranial pathology or underlying systemic disease. Obesity was reported as a sig...

Background: Polycystic ovary syndrome (PCOS) is characterized by ovulatory dysfunction and excess androgen secretion. Androgens may affect bone marrow cells via androgen receptor which expressed in the bone marrow. Also it is known that especially testosterone increases hemoglobin and hematocrit concentrations.Objective and hypotheses: Our aim in this study is to describe the relation between hyperandrogenism and complete blood count (CBC) parameters in ...

Background: Maturity-onset diabetes of the young type 2 (MODY2) is an autosomal dominant inherited disease caused by heterozygous inactivating mutations in the glucokinase (GCK) gene. It mostly presents with mild fasting hyperglycaemia. MODY2 accounts for 2%–5% of all diabetes cases. It is treated with diet only, and complications are extremely rare. We presented here a family with MODY2 caused by a novel heterozygous p.E51*(c.151.G>T) mutation of the GCK gene.<p ...

Background: Metabolic syndrome (MS) is increasingly reported in obese children. So far, MS evaluations were performed for children at the age of 10 and over.Objective and hypotheses: Our aim is to evaluate the prevalence of MS and insulin resistance (IR) in obese children between 3 and 9 years old according to modifying National Cholesterol Education Program Adult Treatment Panel-III (NCEP-III) and International Diabetes Federation (IDF) criteria.<p ...

Background: It has been reported that there is a relationship between circulating leptin and sex steroid hormones and leptin is able to stimulate estrogen secretion by increasing aromatase activity in adipose stromal cells and breast tissue. Leptin receptors have been also shown in mammary epitheleal cells and it has been suggested that leptin is involved in the control of the proliferation of both normal and malignant breast cells.Objective and hypothes...

Background: Maturity-Onset Diabetes of the Young (MODY) is a rare monogenic form of diabetes that result in β-cell dysfunction. MODY accounts for 2–5% of all diabetes cases. We presented here a family with MODY2 caused by a novel heterozygous p.L164I (c.490 C>A) mutation of the GCK gene.Case: A 15,5-year-old girl was admitted to our department because of fasting hyperglycemia. She had no polyuria, polydipsia and weight loss...

Background: Macro TSH is a high molecule weighed complex with low bioactivity that is comprised of TSH and anti-TSH antibodies. Potentiality of macro TSH should be kept in mind in clinically euthyroid and asymptomatic patients with normal free T4 and T3 levels and relatively high TSH levels. Diagnosis of macro TSH is suspected if polyethylene glycol (PEG) precipitable TSH exceeds %75 and confirmed if high molecule weighed TSH is shown with gel filtration ...
