ABSTRACT
Objective: To assess the incidence of type 1 diabetes mellitus (T1DM) in children under 18 years of age in the northwest region of Turkey during 2013-2015. Methods: All newly diagnosed T1DM cases were recorded prospectively during 2013-2015. Total, as well as gender and age group specific (0-4, 5-9, 10-14 and 15-17 age) mean incidences per 100,000 per year were calculated. Results: There were 1,773 patients diagnosed during 2013-2015 (588 cases in 2013, 592 cases in 2014, 593 cases in 2015). Of these, 862 (48.6%) were girls and 911 (51.4%) were boys. The mean age at diagnosis was 9.2±4.2 years and it was not significantly different between girls (9.0±4.1 years) and boys (9.4±4.4 years) (p=0.052). The crude mean incidence was 8.99/100.000 confidence interval (CI) (95% CI: 8.58-9.42). Although mean incidence was similar between boys [8.98/100.000 (CI: 8.40 to 9.58)] and girls [9.01/100.000 (CI: 8.42 to 9.63)], there was male predominance in all groups except for 5-9 year age group. The standardized mean incidence was 9.02/100.000 according to the World Health Organization standard population. The mean incidence for the 0-4, 5-9, 10-14 and 15-17 age groups was 6.13, 11.68, 11.7 and 5.04/100.000 respectively. The incidence of T1DM was similar over the course of three years (p=0.95). A significant increase in the proportion of cases diagnosed was observed in the autumn-winter seasons. Conclusion: The northwest region of Turkey experienced an intermediate incidence of T1DM over the period of the study.

STUDY OBJECTIVE: To investigate the characteristics of children with ovarian cysts and evaluate treatment strategies. DESIGN: Retrospective study. SETTING: Eight pediatric endocrinology clinics, Turkey. PARTICIPANTS: A total of 100 children and adolescents with ovarian cysts. INTERVENTIONS: Patient data collected via retrospective chart review. Patients were stratified according to age into 4 groups (newborns, 1-12 months, 1-8 years, and 8-18 years). MAIN OUTCOME MEASURES: Special emphasis was given to torsion and tumor cases, concomitant diseases, treatment modalities, and problems during follow-up. RESULTS: Most newborns and infants were asymptomatic with the cysts being discovered incidentally; in girls ages 1-8, symptoms were common, including breast budding (47.1%, 16 of 34) and vaginal bleeding (29.4%, 10 of 34). Girls older than 8 years mostly presented with abdominal pain (31.6%, 12 of 38) and menstrual irregularity (21.1%, 8 of 38). Most of our patients were diagnosed with a simple ovarian cyst, but 9 patients were found to have ovarian tumors. Ovarian torsion was detected in 7 patients; 5 with large and 2 with small cysts (<20 mm). Two patients had central precocious puberty (CPP) at presentation and 5 patients developed CPP during follow-up. The surgical intervention rate was high (38%, 38 of 100), but was associated with earlier treatment year, and this association remained significant after adjusting for confounders (P = .035). CONCLUSION: Most girls have simple cysts, which have a favorable prognosis without intervention; however, there might be coexisting pathologies or complications such as tumors, torsion, and CPP; hence these patients should be evaluated accordingly and treated with a multidisciplinary approach.

OBJECTIVES: Type 1 diabetes is a chronic disease that causes persistent vascular injury. This study investigates the benefits of surrogate markers in early detection of vascular injury in children and adolescents with type 1 diabetes. METHODS: Eighty-four patients (35 male, 49 female) with type 1 diabetes for 5 or more years were included. Serum lipid profile, plasminogen activator inhibitor-1 (PAI-1), lipoprotein (a) (Lpa) and homocystein, were investigated. Patients were divided into two groups according to the duration of diabetes. Patients with and without microvascular complications were also compared. RESULTS: Microvascular complications were present in 14 out of 48 patients in group-1 (29.1%; duration of diabetes: 5-10 years) and in 7 out of 36 patients in group-2 (19.4%; duration of diabetes: >10 years). Serum homocystein, Lpa, PAI-1 and serum lipids were not correlated with the duration of diabetes. Significantly increased triglyceride (TG) and HbA1C levels were associated with the presence of microvascular complications. CONCLUSION: Providing good glycemic control is very important for preventing vascular injury in children and adolescents with type 1 diabetes. It seems that traditional vascular surrogate markers like LDL/HDL ratio, triglycerides and HbA1C level correspond more to microvascular complications than newly defined surrogate markers that are not commonly available.
