Introduction: Metabolic syndrome (MS) is a group of cardiovascular risk factors including hyperglycemia, elevated blood pressure, elevated triglycerides levels, central obesity, and low HDL cholesterol. Population studies results show MS to be useful in predicting cardiovascular morbidity and mortality. Objective: Examine the frequency and importance of metabolic syndrome and its components in outpatients. Methods: The study included 178 (71.26±8.93) outpatients, selected by random sample, 67 (71.24±9.5) men and 111 (71.28±11.29) women (p>0.05). Nutrition status was estimated based on anthropometric parameters (body height, body weight, waist circumference). Glycemia, HDL cholesterol, triglycerides, and blood pressure values were measured in all participants. The criteria of the American Heart Association (AHA/NHLBI) were used to diagnose MS. Results: MS was diagnosed in 42.7% of the patients, 31.6% of men and 68.4% of women. The incidence of MS was higher in women (47.7%) than men (35.8%) (p>0.05). In subjects with MS, three components were found in 51.3%, four components in 42.1% and five in 6.6%. Considering individual MS components, the increased waist circumference had the highest incidence of 92.1%. Among the patients with coronary heart disease (CHD), 10.2% had MS, and among those without MS only 1.96% (p

Introduction. Excess body weight, especially when associated with increased visceral obesity, is the major cause of arterial hypertension. It has been found that the correlation between arterial blood pressure and obesity is significant but low. Objective. The aim was to determine frequency of hypertension and to examine the relationship between the body mass index (BMI) and the value of blood pressure in different categories of patients. Method. The study included 150 outpatients. Based on the value of BMI subjects were assigned to different obesity categories. Results. Obese people have a significantly higher incidence of hypertension (p 0.05) and a positive, minor correlation between BMI and diastolic pressure (r=0.145; p> 0.05). Conclusion. Positive correlation between body mass index (BMI) and systolic and diastolic blood pressure, significantly higher incidence of hypertension and findings of significantly higher systolic and diastolic pressure, in obese people, compared to people with normal weight, indicates that obesity is a significant risk factor for arterial hypertension.

Background/Aim. Children with type 1 diabetes typically spend one-third of the day in school and they should achieve the same level of diabetes management there as they do outside the school environment. The aim of this study was to identify problems in diabetes management in children with type 1 diabetes at school according to the perceptions reported by children and parents. Methods. This crosssectional survey was carried out at nine public hospitals in Serbia with a cohort of 6-18-year old children/adolescents. The parents were personally informed about the objectives of the survey and the necessity to involve their children. The self-reporting questionnaire included demographic information as well as some questions that helped to evaluate the general situation of children with type 1 diabetes at school. Results. The obtained results show that not all children test blood glucose levels at school (50% of children in the 6-10- year-old age group and 67.3% in the age group over 11 years) and that not all children receive insulin at school (81.1% vs 18.9%, and 57.7% vs 42.3%, respectively). The frequency of severe hypoglycemia was 2.7% in children and 3.3% in adolescents. A high proportion of teachers did not have diabetes training. Conclusion. This brief report about problems in children and adolescents with type 1 diabetes at school in Serbia indicates what happens in the school setting and suggests how to improve control of this disease and facilitate the complete integration of children with diabetes at school.

Introduction. Galactocele, generally occuring in young women during or after lactation, is an extremely rare cause of breast enlargement in infants and children of exclusively male gender. Only 26 cases have been published so far, including two our cases. Case report. We described unilateral, cystic, breast enlargement, without any endocrinologic and other abnormalities in a 29-month-old boy. A typical clinical and histopathologic presentation of galactocele was followed with a complete excision. Conclusion. This was a 27th well documented case of galactocele in a male infant with typical clinical and histopathologic presentation. There are several hypotheses regarding etiology of the lesion, but it is likely to be multifactorial. Because of its extreme rarity, there are some difficulties in differential diagnosis and treatment options of galactocele in male infants.

Background/Aim. Although total body irradiation (TBI) was considered to be the primary cause of thyroid dysfunction following hematopoietic stem cells transplantation (HSCT), a significant prevalence of subclinical hypothyroidism after HSCT with chemotherapy-only conditioning regimens has been observed in several studies. The aim of this study was to assess changes in thyroid stimulating hormone (TSH) levels in children after HSCT, without the use of irradiation at any time in the course of the treatment. Methods. Our cohort consisted of 41 children and adolescents who underwent autologous or allogeneic HSCT and were available for follow-up for at least one year after transplantation. Irradiation was not performed in any of the subjects, neither during pretransplatation therapy, nor during conditioning. The median duration of follow-up was 2.9 years. The indications for HSCT were hematologic malignancy (41.5%), solid malignant tumor (34.1%), and other disorders (24.4%). The thyroid status of all the subjects was assessed prior to HSCT and after follow-up period. Results. Thyroid dysfunction after HSCT was present in 27 (65.8%) subjects. Subclinical hypothyroidism was the most common abnormality, presenting in 23 (56.1%) patients, primary hypothyroidism was present in one (2.4%) patient, while 3 (7.3%) subjects had low free T4 with normal TSH values. Significantly (p < 0.01) higher elevations in TSH levels were present in the patients who received chemotherapy for the underlying disease prior to HSCT. Conclusion. Our findings emphasize the need for long-term monitoring of thyroid function following HSCT, regardless of whether or not irradiation was used.

Background/Aim. An ideal insulin regimen for children and adolescents with type 1 diabetes mellitus (T1DM) should be physiological, flexibile and predictable, protecting against hypoglycaemia. The aim of this study was to evaluate the influence of insulin analogues on glycaemic control and the occurrence of hypoglycaemic episodes in children and adolescents with T1DM. Methods. The study group consisted of 151 children and adolescents (90 boys, 61 girls) treated with human insulins for at least 12 months before introducing insulin analogues. All the patients were divided into two groups: the group I consisted of 72 (47.7%) patients treated with three injections of regular human insulin before meals and long-acting analogue (RHI/LA), and the group II of 79 (52.3%) patients treated with a combination of rapid-acting and long-acting analogue (RA/LA). The levels of glycated hemoglobin (HbA1c) and the number of hypoglycaemic episodes were assessed at the beginning of therapy with insulin analogues, and after 6 and 12 months. Results. The mean HbA1c was significantly lower in the group I (RHI/LA) after 6 months (9.15% vs 8.20%, p < 0.001) and after 12 months (9.15% vs 8.13%, p < 0.001) as well as in the group II (RA/LA) after 6 months (9.40% vs 8.24%, p < 0.001) and after 12 months of insulin analogues treatment (9.40% vs 8.38%, p < 0.001). The frequency of severe hypoglycaemia was significantly lower in both groups after 6 months (in the group I from 61.1% to 4.2% and in the group II from 54.4% to 1.3%, p < 0.001), and after 12 months (in the group I from 61.1% to 1.4% and in the group II from 54.4% to 1.3%, p < 0.001). Conclusion. Significantly better HbA1c values and lower risk of severe hypoglycaemia were established in children and adolescents with T1DM treated with insulin analogues.

Introduction. Differentiated thyroid carcinoma (DTC) is a rare childhood malignancy, as it represents 0.3-0.4% of pediatric malignancies. Papillary carcinoma is the most common type of pediatric DTC and it represents about 90% of all DTC patients. Although rare, DTC arising from dyshormonogenetic goiter is the most serious complication of congenital hypothyroidism. Case report. We presented the development of thyroid papillary carcinoma in a 15-year-old girl diagnosed with congenital dyshormonogenetic hypothyroidism at neonatal age. Considering the early initiation and proper dosage of hormonal substitution, normal levels of thyreotropin and thyroid hormones were achieved quickly and maintained through a follow-up period. The girl remained euthyroid and asymptomatic until 13.8 years of age, when she presented with a large multinodular goiter. The patient underwent total thyroidectomy. Pathological examination revealed intrathyroid microcarcinoma in the right lobe. Conclusion. Although differentiated thyroid carcinoma is a rare pediatric malignancy, it is of great importance to have a certain degree of clinical caution and provide a multidisciplinary approach during the follow-up of patients with dyshormonogenetic hypothyroidism.
