Abstract

The aim of this study was to investigate the physiological and biochemical parameters of children who are experiencing breath-holding spells (BHS) and to compare the function of their autonomic nervous systems with those of healthy children. A total of 30 children (age range, 6 months-5 years) admitted for BHS were included in the study. The control group consisted of 30 age-matched and gender-matched healthy children. Each participant underwent a detailed physical examination as well as a laboratory evaluation. Echocardiography, electrocardiography (ECG), and electroencephalography were performed in the study group. The pilocarpine eye test was administered to each participant to detect autonomic dysfunction. No statistically significant differences were found between the groups for mean age, gender, and anthropometric measurements, nor for the biochemical parameters, including hemoglobin concentration, hematocrit, serum iron, transferrin saturation, ferritin, vitamin D, and vitamin B12 levels (p = 0.05). Compared with the control group, the study group showed significantly abnormal hypersensitivity of pupils after instillation of pilocarpine into their eyes (p = 0.01). Autonomic dysfunction existed in the children with BHS, b...Continue Reading

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
