RESUMO

Objective: Diabetic ketoacidosis (DKA) is an important complication of type 1 diabetes mellitus. We aimed to evaluate the effect of metabolic disorders of DKA on electrocardiography (ECG) parameters in children. Methods: This study was performed between December 2018 and March 2020 and included 39 children with DKA and 40 healthy children. Three ECGs (one before and two after treatment) were obtained from the patient group. P-wave dispersion (Pd), QT dispersion (QTd), QTc dispersion (QTcd), Tp-e intervals, and the ratios of Tp-e/QT and Tp-e/QTc were measured electrocardiographically. ECG parameters from children with DKA and healthy controls were compared statistically. Results: The mean age of the patient group was 10.50±4.12 years. There was no significant difference in terms of age, gender, weight, height and body mass index between patients and controls. In the patient group, a statistically significant increase was found in Pd, QTd and QTcd in the initial ECG compared to the second and third ECGs. Also, when the first and third ECGs were compared, a significant increase in Tp-e and Tp-e/QT was evident in the first ECG. There was a significant difference in the values of Pd, QTd, QTcd, Tp-e and Tp-e/QT in the first ECGs, obtained before DKA treatment, and those values obtained from the control group. Conclusion: This is the first article evaluating Pd and Tp-e parameters in children with DKA. Cardiac arrhythmia risk markers were increased in children with DKA compared to controls. Therefore, clinicians should be aware of the possibility of developing new arrhythmias during DKA treatment.

RESUMO

Objectives Investigation of the association between epicardial adipose tissue thickness (EATT) and P-wave dispersion (Pd), QT dispersion (QTd), corrected QT dispersion (QTcd) and Tp-e interval in children with Type 1 Diabetes Mellitus (T1DM) was aimed. Methods Forty-one children with T1DM and 41 age- and gender-matched healthy children were included in the study. Demographical characteristics of all cases were examined. In echocardiography; in addition to conventional echocardiographic measurements, end-systolic EATT was measured from right ventricular free wall. In electrocardiogram; Pd, QTd, QTcd and Tp-e interval durations, as well as Tp-e/QT and Tp-e/QTc ratios were calculated. Correlation values between EATT and electrocardiographic parameters were also noted. Results Mean age of the patient group was determined to be 12.43 ± 3.04 years and that of the control group was determined to be 12.08 ± 2.56 years. There was no significant difference between the groups in regard to age, gender, body weight, height and body mass index. In the patient group; EATT, Pd, QTd, QTcd and Tp-e interval were determined to be significantly higher compared to the control group. In the patient group, no significant correlation was determined between EATT and Pd, QTd, QTcd and Tp-e. However, when both patient and control groups were evaluated together, a statistically significant positive correlation was determined between EATT and Pd, QTd, QTcd and Tp-e. Conclusions In children with T1DM, an increase in epicardial adipose tissue thickness and in risk of cardiac arrhythmias has been demonstrated. To reveal the possible unfavorable effects of EATT on cardiac conduction system in T1DM patients needs further studies.

RESUMO

Background Autoimmune thyroid diseases (ATDs) can be classified into two basic diseases: Graves' disease (GD) and Hashimoto's thyroiditis (HT). Here, we review the effectiveness of laboratory and imaging methods used for the early diagnosis of ATD and draw attention to methods that may improve screening. Methods Retrospective data of 142 patients diagnosed with ATD between January 2010 and December 2015 at our paediatric endocrinology clinic were used. Sociodemographic characteristics, clinical findings, treatments and follow-up data of patients were statistically evaluated. Results Of the ATD cases, 81% (n = 115) were female. The median age was 12.5 ± 3.5 (range 1-17) years and 91% (n = 129) of patients were in puberty. There was a significant positive correlation between the height (standard deviation score) and follow-up time for patients with HT (r = 0.156, p < 0.01). Thyroglobulin antibody (TgAb) positivity was found in 75% (45/60) of females with a positive maternal ATD history (p = 0.045). Thyroid-stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4) values were significantly altered during the treatment follow-up period in female patients with GD and HT, while only fT4 values were found to be significantly altered in boys with HT. Conclusion Although GD and HT have similar mechanisms, they differ in terms of treatment duration and remission and relapse frequencies. Ultrasonography (USG) screening is a non-invasive procedure that is suitable for all patients with ATD. Based on our results, TgAb could be useful in the screening of girls with a history of maternal ATD.

RESUMO

OBJECTIVES: Acanthosis nigricans is a skin symptom in obesity that helps to identify patients at high risk for dyslipidemia, hypertension, insulin resistance, and diabetes. It is the most important complication of obesity in metabolic syndrome. Studies investigating the relationship between acanthosis nigricans and metabolic syndrome in obese children are insufficient. In our study, the relationship of acanthosis nigricans and metabolic syndrome was evaluated in children. METHODS: Obese children aged between 6 and 18 years old, who were examined in the pediatric endocrinology outpatient clinic, were included. The patients' anthropometric measurements and laboratory results were recorded. Modified IDF (International Diabetes Federation) criteria for children were used in metabolic syndrome classification. RESULTS: A hundred and forty-eight obese children were evaluated. The mean age of the cases was 11.91 ± 2.94 years old. Of the cases, 56.1% were female (n=83) 43.9% (n=65) were male. In 39.9% (n=59) of cases, acanthosis nigricans was determined. Acanthosis nigricans was mostly located in the axillary area (27.1%) and the neck (16.9%). In 55.9% of the cases, it was located in more than one area. The relation of regionally detected acanthosis nigricans and metabolic syndrome was not significant (p=0.291). Metabolic syndrome was detected in 14% of 136 patients according to IDF criteria. Acanthosis nigricans and metabolic syndrome combination was present in 27.7%; however, 6.7% of the metabolic syndrome patients did not have acanthosis nigricans. There was a strong relation between metabolic syndrome and the presence of acanthosis nigricans (p=0.003). CONCLUSIONS: In our study, a correlation between acanthosis nigricans and metabolic syndrome was detected. Acanthosis nigricans is a skin sign that can be easily detected by clinician. It is an important and easy-to-detect dermatosis that helps determine patients at risk of metabolic syndrome in obese children.

RESUMO

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.

RESUMO

Isolated aldosterone synthase deficiency may result in life-threatening salt-wasting and failure to thrive. The condition involves hyperkalemia accompanying hyponatremia. Two types of aldosterone synthase deficiency may be observed depending on hormone levels: corticosterone methyl oxidase type 1 (CMO 1) and CMO 2. Herein, we describe a Turkish infant patient with aldosterone synthase deficiency who presented with failure to thrive and salt wasting but with normal potassium levels. Urinary steroid characteristics were compatible with CMO I deficiency. Diagnosis of aldosterone synthase deficiency was confirmed by mutational analysis of the CYP11B2 gene which identified the patient as homozygous for two mutations: c.788T>A (p.Ile263Asn) and c.1157T>C (p.Val386Ala). Family genetic study revealed that the mother was heterozygous for c.788T>A and homozygous for c.1157T>C and the father was heterozygous for both c.788T>A and c.1157T>C. To the best of our knowledge, this is only the second Turkish case with a confirmed molecular basis of type 1 aldosterone synthase deficiency. This case is also significant in showing that spot urinary steroid analysis can assist with the diagnosis and that hyperkalemia is not necessarily part of the disease.

RESUMO

OBJECTIVE: To evaluate the relationship between periaortic fat thickness (PAFT) and parameters involved in the development of metabolic complications of the cardiovascular system in obese children and to assess the usefulness of echocardiographic measurements of PAFT in correlation with cardiovascular risk factors. METHODS: The study was conducted with 263 obese and 100 healthy children and adolescents. PAFT was measured with echocardiography method which was recently performed in obese children and adolescents. RESULTS: PAFT was significantly higher in the obese group (0.258±0.031 mm) than in the control group (0.137±0.032 mm) (p<0.001). In multivariable regression analysis, body mass index-standard deviation score and total body fat were predictors of PAFT. The area under the receiver operating characteristic curve was 0.989 and was quite significant at p<0.001. PAFT above 0.179 mm was determined as the cut-off value in obese children and adolescents (sensitivity=1, specificity=0.97). CONCLUSION: The measurement of PAFT in obese children and adolescents may be a good method to reveal the presence of early cardiovascular risk.

RESUMO

To evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study. In this cohort, the frequency of small for gestational age (SGA) birth was 33%. The frequency of SGA birth was 4.2% (2/48) in preterm and 36% (174/483) in term neonates (P < 0.001). The mean birth length was 1.3 cm shorter and mean birth weight was 0.36 kg lower than that of the normal population. The mean age at diagnosis was 10.1 ± 4.4 years. Mean height, weight and body mass index standard deviation scores at presentation were -3.1 ± 1.7, -1.4 ± 1.5, and 0.4 ± 1.7, respectively. Patients with isochromosome Xq were significantly heavier than those with other karyotype groups (P = 0.007). Age at presentation was negatively correlated and mid-parental height was positively correlated with height at presentation. Mid-parental height and age at presentation were the only parameters that were associated with height of children with TS. The frequency of SGA birth was found higher in preterm than term neonates but the mechanism could not be clarified. We found no effect of karyotype on height of girls with TS, whereas weight was greater in 46,X,i(Xq) and 45,X/46,X,i(Xq) karyotype groups.

RESUMO

OBJECTIVE: In this study, our aim was to determine cardiovascular risk and cardiac function in prediabetic obese children and adolescents. METHODS: The study was conducted on 198 obese children and adolescents 6-18 years of age. Anthropometric measurements, blood pressure measurements, oral glucose tolerance test, lipid profile, and HbA1c levels of patients were assessed. Prediabetes was defined according to American Diabetes Association criteria. Left ventricular mass index (LVMi), carotid intima-media thickness (c-IMT), and tissue Doppler measurements records were used. RESULTS: LVMi was found to be significantly higher in the prediabetes group (p=0.03). There were no statistically significant differences in right ventricular tissue Doppler measurements between the prediabetic and non-prediabetic groups. Left ventricular tissue Doppler measurements were significantly higher in the prediabetes group: LVEEM (left ventricular E/e ratio) (p=0.04); LVEM (left ventricular myocardial velocity cm/s) (p=0.035). LVMi was found to positively correlate with triglyceride level, diastolic blood pressure, waist circumference, body weight standard deviation score and to negatively correlate with high-density lipoprotein cholesterol (p=0.043, r=0.15; p=0.039, r=0.15; p=0.025, r=0.17; p=0.009, r=0.19; p=0.038, r=-0.15, respectively). LVEM was correlated with glucose (p=0.046, r=0.15) and LVEEM was correlated with systolic blood pressure (p=0.035, r=0.15). In linear regression analysis for clinical cardiovascular risk factors, fasting glucose level was the best predictor of LVEM. CONCLUSION: In this study, deterioration of cardiac function in prediabetic obese children and adolescents was shown. We recommend determining cardiovascular risk and cardiac dysfunction at early stages in prediabetic obese children and adolescents.

RESUMO

BACKGROUND: Ovotesticular disorders of sexual development (OT-DSD) represent a rare sex development disorder characterized by the presence of both ovarian and testicular tissues in the same or the contralateral gonad. CASE: We present the case of a 14-year-old female patient with signs of virilization at a pubertal age and with dysmorphic features, diagnosed as 46,XX OT-DSD. CONCLUSION: We want to point out that patients with 46 XX OT-DSD may present with virilization at puberty and may be accompanied by dysmorphic features.

RESUMO

OBJECTIVE: There is an increased risk of cardiovascular morbidity in children and adolescents with classical congenital adrenal hyperplasia (CAH), presumably associated with obesity, hypertension, impaired glucose tolerance and dyslipidemia. This study was designed to evaluate the metabolic and cardiovascular profile of a group of children with classical CAH from the perspective of cardiovascular risk. METHODS: Twenty-five CAH patients and 25 healthy controls were included in the study. Metabolic and anthropometric parameters were investigated and compared in these two groups. RESULTS: Subjects in the CAH group were shorter than the controls (p=0.001) and had higher body mass index values (p=0.033). Diastolic blood pressure (DBP) (p=0.027) and carotid intima-media thickness (CIMT) values (p=0.006) were also higher in the patient group. In 24% (n=6) of CAH patients, 24-h ambulatory BP monitoring showed arterial hypertension. CIMT was significantly higher in the hypertensive patients than in those with no hypertension (p=0.013). Twenty percent (n=5) of CAH patients had nocturnal hypertension. CIMT was significantly greater in the nocturnal hypertensive group (p=0.02). Mean systolic BP (SBP) and DBP dipping were significantly different in the CAH patients (p<0.001). CIMT correlated negatively with DBP dipping (r=-0632, p=0.037) in these patients. CONCLUSION: These results provide additional evidence for the presence of subclinical cardiovascular disease in classical CAH patients and its relationship with hypertension.

RESUMO

OBJECTIVE: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population. METHODS: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014. RESULTS: The most common karyotype was 45,X (50.7%), followed by 45,X/46,XX (10.8%), 46,X,i(Xq) (10.1%) and 45,X/46,X,i(Xq) (9.5%). Mean age at diagnosis was 10.2±4.4 years. The most common presenting complaints were short stature and delayed puberty. Among patients diagnosed before age one year, the ratio of karyotype 45,X was significantly higher than that of other karyotype groups. Cardiac defects (bicuspid aortic valve, coarctation of the aorta and aortic stenosis) were the most common congenital anomalies, occurring in 25% of the TS cases. This was followed by urinary system anomalies (horseshoe kidney, double collector duct system and renal rotation) detected in 16.3%. Hashimoto's thyroiditis was found in 11.1% of patients, gastrointestinal abnormalities in 8.9%, ear nose and throat problems in 22.6%, dermatologic problems in 21.8% and osteoporosis in 15.3%. Learning difficulties and/or psychosocial problems were encountered in 39.1%. Insulin resistance and impaired fasting glucose were detected in 3.4% and 2.2%, respectively. Dyslipidemia prevalence was 11.4%. CONCLUSION: This comprehensive study systematically evaluated the largest group of karyotype-proven TS girls to date. The karyotype distribution, congenital anomaly and comorbidity profile closely parallel that from other countries and support the need for close medical surveillance of these complex patients throughout their lifespan.

RESUMO

OBJECTIVE: Approaches to diagnosis and treatment of growth hormone deficiency (GHD) in children vary among countries and even among centers in the same country. This survey, aiming to facilitate the process of preparing the new consensus on GHD by the Turkish Pediatric Endocrinology and Diabetes Society, was designed to evaluate the current practices in diagnosis and treatment of GHD in different centers in Turkey. METHODS: A questionnaire covering relevant items for diagnosis and treatment of GHD was sent out to all pediatric endocrinology centers. RESULTS: Twenty-four centers returned the questionnaire. The most frequently used GH stimulation test was L-dopa, followed by clonidine. Eighteen centers used a GH cut-off value of 10 ng/mL for the diagnosis of GHD; this value was 7 ng/mL in 4 centers and 5 ng/mL in 2 centers. The most frequently used assay was immunochemiluminescence for determination of GH, insulin-like growth factor-1 and insulin-like growth factor binding protein-3 concentrations. Sex steroid priming in both sexes was used by 19 centers. The most frequently used starting dose of recombinant human GH (rhGH) in prepubertal children was 0.025-0.030 mg/kg/day and 0.030-0.035 mg/kg/day in pubertal children. Growth velocity was used in the evaluation for growth response to rhGH therapy in all centers. Anthropometric measurements of patients every 3-6 months, fasting blood glucose, bone age and thyroid panel evaluation were used by all centers at follow-up. Main indications for cessation of therapy were decreased height velocity and advanced bone age. Fourteen centers used combined treatment (rhGH and gonadotropin-releasing analogues) to increase final height. CONCLUSION: Although conformity was found among centers in Turkey in current practice, it is very important to update guideline statements and to modify, if needed, the approach to GHD over time in accordance with new evidence-based clinical studies.

RESUMO

Children with Turner syndrome (TS) have a broad range of later health problems, including an increased risk of cardiovascular morbidity and mortality. The aim of this study was to evaluate the relationship between periaortic fat thickness (PAFT) and metabolic and cardiovascular profiles in children with TS. Twenty-nine TS and 29 healthy children and adolescents were enrolled in the study. Anthropometric measurements, pubertal staging, and blood pressure measurements were performed. Fasting serum glucose, insulin, and lipid profile were measured. Periaortic fat thickness was measured using an echocardiography method, which has not previously been applied in children with TS. No difference was found between TS and control subject (CS) in age, weight, waist/hip ratio, HDL cholesterol and LDL cholesterol levels. However, in TS subjects, total cholesterol (p = 0.045) was greater than that in controls. It was determined that 13.7 % (N: 4) of TS subjects had dyslipidemia. Mean fasting glucose, fasting insulin, QUICK-I, HOMA, and FGIR index were similar in TS and in CS, whereas 17.2 % (N: 5) of TS subjects had insulin resistance (IR) and 13.7 % (N: 4) had impaired glucose tolerance. Six subjects (20.6 %) were diagnosed as hypertensive. Periaortic fat thickness was significantly higher in the TS group (p < 0.001) (0.1694 ± 0.025 mm in the TS group and 0.1416 ± 0.014 mm in the CS group) In children with TS, PAFT was positively correlated with fasting insulin, body mass index, and diastolic blood pressure. Our results provide additional evidence for the presence of subclinical cardiovascular disease in TS. In addition to existing methods, we recommend the measurement of periaortic fat thickness in children with TS to reveal the presence of early atherosclerosis.

RESUMO

AIM: In this study, parameters of metabolic syndrome and dehydroepiandrosterone sulfate (DHEAS) levels in obese children and adolescents were evaluated and the associations between these factors were analyzed. METHOD: One hundred obese and 40 healthy children/adolescents were included in the study. Pubertal stages, anthropometric and blood pressure measurements were recorded. Levels of fasting serum lipids, glucose, insulin, and DHEAS, and liver function tests were determined. Carotid intima-media thickness (CIMT) was measured using two-dimensional echocardiography. Steatorrhoeic hepatosis was evaluated using abdominal ultrasonography in the obese group. RESULTS: Mean body weight, body mass index, waist, hip circumference, waist/hip ratio, homeostatic model assessment of insulin resistance, triglycerides, high-density lipoprotein cholesterol, alanine transferase, DHEAS, and CIMT values were significantly higher in the obese group than in the controls. DHEAS levels were found to be positively correlated with waist circumference, waist/hip ratio, and CIMT. CONCLUSION: Early determination of metabolic and cardiac dysfunction in obese children is important for the prevention of future complications. Since in this study we found a strong association between DHEAS levels and obesity-related metabolic and cardiovascular risk factors, we believe that this may lead to increased interest in further studies of DHEAS in the search for new treatment approaches.

RESUMO

OBJECTIVE: Children with Turner syndrome (TS) have a specific growth pattern that is quite different from that of healthy children. Many countries have population-specific growth charts for TS. Considering national and ethnic differences, we undertook this multicenter collaborative study to construct growth charts and reference values for height, weight and body mass index (BMI) from 3 years of age to adulthood for spontaneous growth of Turkish girls with TS. METHODS: Cross-sectional height and weight data of 842 patients with TS, younger than 18 years of age and before starting any therapy, were evaluated. RESULTS: The data were processed to calculate the 3rd, 10th, 25th, 50th, 75th, 90th and 97th percentile values for defined ages and to construct growth curves for height-for-age, weight-for-age and BMI-for-age of girls with TS. The growth pattern of TS girls in this series resembled the growth pattern of TS girls in other reports, but there were differences in height between our series and the others. CONCLUSION: This study provides disease-specific growth charts for Turkish girls with TS. These disease-specific national growth charts will serve to improve the evaluation of growth and its management with growth-promoting therapeutic agents in TS patients.

RESUMO

OBJECTIVE: The aim of this study was to evaluate the periaortic fat thickness (PAFT) using conventional echocardiography in obese children and adolescents with non-alcoholic fatty liver disease (NAFLD). METHODS: Two hundred and ninety-seven obese children and adolescents were included in the study. Anthropometric measurements were made in all subjects, and fasting venous blood samples were taken for determination of glucose, insulin, total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, triglycerides, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Ultrasonography of the liver was used for assessment of NAFLD and the subjects were grouped as NAFLD and non-NAFLD. Echocardiography was performed in all subjects. RESULTS: PAFT was higher in patients with NAFLD compared with the non-NAFLD group. In patients with NAFLD, PAFT was positively correlated with waist circumference and with total cholesterol levels. In multiple regression analysis, waist circumference (ß=0.28, p=<0.001) was found to be the best predictor of PAFT. CONCLUSION: Conventional echocardiography may be used to determine increased PAFT at an early stage in obese children and adolescents with NAFLD for careful monitoring of cardiovascular risk.

RESUMO

OBJECTIVES: The aim of the present study was to determine the level of ischemia-modified albumin (IMA) in children with epileptic seizures (ESs) and its relation with the seizure duration. METHODS: The study was performed with 88 children as a prospective case-control study. Blood samples for IMA were obtained from 57 patients (mean age [SD], 50.86 [51.15] months) within 3 hours after ES and 31 healthy control subjects (mean age [SD], 53.13 [40.87] months). Ischemia-modified albumin was measured by the albumin cobalt binding test. RESULTS: Although the mean (SD) of serum IMA level of the patients with seizure was 13.66 (13.16) U/mL, the mean (SD) of serum IMA level for the control group was 3.73 (1.93) U/mL. Ischemia-modified albumin levels were significantly higher in patients with seizure, compared with that in the control group (P < 0.01). When patients were grouped in itself according to the duration of ESs, the levels of IMA were detected to be increased in patients as the duration of seizures was lengthened. CONCLUSIONS: Increased IMA levels after seizures suggest that IMA assay during seizure may be useful for predicting the diagnosis and severity of convulsion.
