The Hepcidin and 25-OH-Vitamin D Levels in Obese Children as a Potential Mediator of the Iron Status.

Background: Obesity is associated with the risk factors such as iron and vitamin D deficiencies. Increased risk of iron deficiency generally correlates with the high levels of serum hepcidin in obese children. Vitamin D deficiency was also linked to an increase in serum hepcidin levels.

Attention-deficit Hyperactivity Disorder Symptoms and Conduct Problems in Children and Adolescents with Obesity.

Objectives: Recent studies focus on the potential factors that increase the potantial risks of obesity in children and adolescents. According to research for the past years, one of the factors that increases the risk of obesity may be attention- deficit hyperactivity disorder (ADHD). We hypothesized that overweight/obese children and adolescents that apply to pediatric endocrinology for treatment would be at higher risk for ADHD symptoms.

Seizures and diagnostic difficulties in hyperinsulinism-hyperammonemia syndrome.

Hyperinsulinism/hyperammonemia (HI/HA) syndrome is a rare disorder presented with recurrent hypoglycemia and elevated serum ammonia, which may lead to development delays, permanent neurologic damages, if it remains underdiagnosed. It is caused by activating mutations in the GLUD1 gene which encodes the intra-mitochondrial enzyme glutamate dehydrogenase (GDH). HI/HA syndrome is considered the second most common form of hyperinsulinism (HI), and usually associated with epileptic seizures, mental retardation and generalized dystonia.

The relationship between bifidobacteria and allergic asthma and/or allergic dermatitis: a prospective study of 0-3 years-old children in Turkey.

Bifidobacteria are beneficial bacteria for humans. These bacteria are particularly effective at protecting against infectious diseases and modulating the immune response. It was shown that in newborns, the fecal distribution of the colonizing Bifidobacterium species influences the prevalence of allergic diseases.

Abdominal aorta intima media thickness in obese children.

The aim of this study is to investigate whether abdominal aorta intima media thickness (aIMT), increases in obese children and to determine risk factors. Ninety-six children aged 5-16 (51 obese and 45 non-obese) were enrolled in this prospective and cross-sectional study. Age, gender, and relative body mass index (BMI) were recorded.

Diagnosis of a trend towards obesity in preschool children: a longitudinal study.

The study was planned to determine identifiable starting points of a trend towards obesity and the influence of variables in preschool children aged 0 to 6 years. In this longitudinal follow-up study, 102 children were enrolled. Anthropometric measurements such as weight-height centiles (specific for gender and age group), weight-height growth velocities, and body mass indices were taken annually and compared within each group from birth to 6 years.

Role of early EEG and neuroimaging in determination of prognosis in children with complex febrile seizure.

Background: The present study investigates the role of early use of EEG in children with no known neuropathology prior to the first CFS, and the contribution made by computed tomography (CT) and magnetic resonance imaging (MRI) to treatment and prognosis.

Methods: Over a period of 7 years, the authors evaluated 159 children (age range: 2 months-5 years) who were being treated for CFS at Haydarpasa Numune Training and Research Hospital, Pediatrics Clinic, Istanbul, Turkey, and who had no previously known neurological disorder. Patients who presented with febrile seizure were determined to have CFS if they fulfilled the following criteria: <3 months of age when seizure occurred, duration of seizure >/=15 min, more than one seizure occurred during a single episode of illness, or focal seizures and postictal neurological deficit was found.

The relationship of tonsillar hyperplasia and asthma in a group of asthmatic children.

Background: The decline of infections in childhood may contribute to the rising severity and prevalence of atopic disorders in developed countries. With this regard, we examined the relationship of frequent tonsillitis and consequent tonsillar hyperplasia with the development of asthma.

Methods: Sixty-seven asthmatic children (ages 3-14) who had no signs or symptoms of acute tonsillitis were included.
