Hypernatremic Dehydration Risk Factors in Newborns: Prospective Case-Controlled Study.

Background: The prevalence of hypernatremic dehydration (HND) has increased in recent years most likely due to insufficient intake of breast milk as the most important factor. This study aimed to investigate risk factors of HND.

Methods: In this study, 47 neonates whom were diagnosed to have HND were included in the study group and 96 healty neonates whom were included in the control group.

Anti-cyclic citrullinated peptide antibodies are not frequently observed in children with type 1 diabetes mellitus: a single-center study.

Type 1 diabetes mellitus (DM) and rheumatoid arthritis (RA) have been reported to occur concurrently in some cases. This study aimed to evaluate the presence of anti-cyclic citrullinated peptide (CCP) antibodies, which have been reported to have diagnostic value for RA, in children with type 1 DM. The study included 90 children with type 1 DM (Group 1) and 76 control cases (Group 2).

Prevalence of thyroid function test abnormalities and thyroid autoantibodies in children with vitiligo.

Although the exact pathogenic processes involved in vitiligo are still unknown, its association with autoimmune disorders and endocrine dysfunction has been reported. One of its associations is with thyroid diseases. The purpose of this retrospective study was to determine the prevalence of thyroid function tests and thyroid autoantibody abnormalities in children diagnosed with vitiligo and compare the results with the literature.

Children with atopic dermatitis do not have more anxiety or different cortisol levels compared with normal children.

Background: The hypothalamic-pituitary-adrenal axis has an important immunoregulatory role under stress, and stress-mediated anxiety has been reported to be associated with alterations in immune functions and attenuated cortisol levels in atopic dermatitis (AD) patients.

Objective: We investigated serum basal cortisol and anxiety levels in pediatric AD patients and compared them with those of controls.

Methods: Basal serum cortisol levels were measured in 36 pediatric AD patients (aged 9-16 years) and 36 control subjects (aged 9-15 years).
