    Amylase/creatinine clearance ratio in diabetic ketoacidosis: a case report
    (Walter De Gruyter Gmbh, 2014) Boybeyi, Ozlem; Ergur, Ayca Torel; Dursun, Zarife Esra; Gulerman, Fulya
    Diabetic ketoacidosis (DKA) accompanies any other intra-abdominal pathology. Serum amylase/lipase levels are commonly used in order to rule out acute pancreatitis in patients having abdominal pain in DKA. A more specific and noninvasive diagnostic tool - amylase/creatinine clearance ratio (ACCR) - can be used to rule out pancreatitis in patients with DKA. A 14-year-old girl was admitted with abdominal pain and nausea. She had been followed up for type 1 diabetes mellitus for the last 5 years. The serum amylase levels were increased up to 687 U/L (normal: 28-120 U/L) on the third day of hospitalization. Simultaneous serum and urinary amylase concentrations were measured, and ACCR was calculated (1.2%). The diagnosis of pancreatitis was ruled out. The serum amylase levels decreased in the following days, and she was discharged. ACCR determination is a simple and specific test to diagnose pancreatitis, especially in patients with DKA.

    An Assesment Of Unexpectedly High Hba1c Level In A Case With Type 1 Diabetes
    (Nobel Ilac, 2016) Candar, Tuba; Ozdemir, Sedat; Ergur, Ayca Torel; Demirtas, Selda
    The HbA1c test provides information about blood glucose levels of previous months depending on the erythrocyte lifetime when monitoring diabetic patients. However, various factors such as HbF and other hemoglobin variants can interfere with the measurement of HbA1c. In this study, an unexpectedly high HbA1c level was observed in a patient with type 1 diabetes. In the hemoglobin chain analysis, which explained the reason for the high value, high fetal hemoglobin levels were detected and interfered with HbA1c measurement with the HPLC method. This finding was in concordance with the literature. As a conclusion, it should be considered that hemoglobinopathy might be found in the patients who have higher levels of HbA1c which is not in agreement with the blood glucose. Thus, it can be said that HbA1c test is not a good marker for monitoring such diabetic patients. In such cases, fructosamine or other glycated end products may be a more reliable marker.

    Clinical and Laboratory Characteristics of Hyperprolactinemia in Children and Adolescents: National Survey
    (Galenos Yayincilik, 2019) Eren, Erdal; Ergur, Ayca Torel; Isguven, Sukriye Pinar; Bitkin, Eda Celebi; Berberoglu, Merih; Siklar, Zeynep; Tarim, Omer
    Objective: We aimed to report the characteristics at admission, diagnosis, treatment, and follow-up of cases of pediatric hyperprolactinemia in a large multicenter study. Methods: We reviewed the records of 233 hyperprolactinemic patients, under 18 years of age, who were followed by different centers. The patients were divided as having microadenomas, macroadenomas, drug-induced hyperprolactinemia and idiopathic hyperprolactinemia. Complaints of the patients, their mode of treatment (medication and/or surgery) and outcomes were evaluated in detail. Results: The mean age of the patients with hyperprolactinemia was 14.5 years, and 88.4% were females. In terms of etiology, microadenomas were observed in 32.6 %, macroadenomas in 27 %, idiopathic hyperprolactinemia in 22.7% and drug-induced hyperprolactinemia in 6.4 %. Other causes of hyperprolactinemia were defined in 11.3%. Common complaints in females (n = 206) were sorted into menstrual irregularities, headaches, galactorrhea, primary or secondary amenorrhea and weight gain, whereas headache, gynecomastia, short stature and blurred vision were common in males (n = 27). Median prolactin levels were 93.15 ng/mL, 241.8 ng/ml, 74.5 ng/mL, 93.2 ng/mL, and 69 ng/mL for microadenomas, macroadenomas, idiopathic hyperprolactinemia, drug-induced hyperprolactinemia, and other causes of hyperprolactinemia, respectively. Of 172 patients with hyperprolactinemia, 77.3 % were treated with cabergoline and 13.4 % with bromocriptine. 20.1 % of the patients with pituitary adenomas underwent pituitary surgery. Conclusion: We present the largest cohort of children and adolescents with hyperprolactinemia in the literature to date. Hyperprolactinemia is more common in females and cabergoline is highly effective and practical to use in adolescents, due to its biweekly dosing. Indications for surgery in pediatric cases need to be revised.

    Does Subclinical Hypothyroidism Affect Dynamic Thiol/Disulfide Homeostasis and ischemia-modified Albumin Levels in Children?
    (COLL PHYSICIANS & SURGEONS PAKISTAN, 2020) Tursun, Serkan; Alpcan, Aysegul; Ergur, Ayca Torel; Karahan, Irfan; Neselioglu, Salim; Erel, Ozcan
    Objective: To determine the effects of subclinical hypothyroidism on oxidative stress in children. Study Design: A cross-sectional study. Place and Duration of Study: Department of Paediatrics, Paediatric Endocrinology, and General Outpatient Clinics, Kirikkale University, School of Medicine, from May 2017 to October 2018. Methodology: This study included 92 subjects aged between 2 and 18 years. The subjects were divided into two groups. Forty-seven children with subclinical hypothyroidism and 45 healthy controls were evaluated. In order to evaluate oxidative damage, native thiol, total thiol, disulfides, their ratios, and ischemia-modified albumin (IMA) levels were compared between the two groups. The relationship between TSH and IMA levels was assessed. Results: Age and gender were not significantly different in the two groups. Native thiol, total thiol, disulfides and their ratios were similar in the two groups. lschemia-modified albumin levels were significantly higher in the patient group than the controls (p<0.001). There was no correlation between TSH and IMA levels in the patient group (r=0.069 p=0.645). Conclusion: Subclinical hypothyroidism may be related to the impairment of IMA, and have a neutral effect on thiol/disulfide balance. Further research is needed to explain the effects of oxidative stress in subclinical hypothyroidism.

    Intracranial Lesions in Children and Adolescents with Morbid Obesity
    (Galenos Yayincilik, 2017) Ergur, Ayca Torel; Gunes, Sevinc Odabasi; Tan, Sinan; Tandircioglu, U. Ayse
    Background: Intracranial lesions may affect the hypothalamo-hypophyseal axis and lead to some neuroendocrinological dysfunctions (hyperphagia, sleep disorders and hormonal dysfunctions). There is a very limited number of studies about childhood obesity and intracranial lesions. Aims: To evaluate the incidence of intracranial lesions and its role in clinical symptoms and aetiology in cases with morbid obesity who have been admitted to the paediatric endocrinology department with this complaint. Study Design: Cross-sectional study. Methods: A total of 120 cases admitted to the paediatric endocrinology department with the complaint of morbid obesity between 2002 and 2015 were included in this study. A detailed history was taken and a physical examination was performed; biochemical, hormonal parameters were evaluated. Contrast dynamic magnetic resonance imaging was performed in order to visualize cranial pathologies. Results: An intracranial lesions was detected in 16.6% of the patients and 55% of these lesions were adenoma of the hypophysis. Prolactin levels were increased in six patients but front hypophyseal hormone levels were within normal range in the rest of the patients. Growth velocity of the patients was not affected. Conclusion: In our study, the incidence of intracranial lesions in children and adolescents with morbid obesity was much higher than in the normal population. According to this data, we are of the opinion that contrast dynamic magnetic resonance imaging is helpful in children with morbid obesity for the early detection of the mass before it causes any clinical or neurological symptoms and in the prevention of future complications.
