Comparison of exhaled nitric oxide levels in pediatric patients with allergic rhinitis.

Objective: To determine whether the measurement of exhaled nitric oxide (eNO) can help distinguish children with allergic rhinitis (AR) from healthy controls and whether eNO in children with AR correlates with disease severity.

Methods: From August 2015 to 2016, children aged 5-15 years of age grouped into those with allergic rhinitis (n = 40) and those classified as healthy control subjects (n = 40) had exhaled nitric oxide (eNO) levels measured. The eNO level was additionally compared to the patient's clinical disease severity according to the ARIA (Allergic Rhinitis and its Impact on Asthma) classification.

Evaluating the impact of allergic rhinitis on quality of life among Thai students.

Background: The prevalence of allergic rhinitis (AR) in Thailand continues to rise. We report the prevalence and evaluate its impact upon quality of life (QoL) in students on a metropolitan campus.

Methods: From March 2013 to February 2014, 222 students from Thammasat University Medical School were evaluated using the International Study of Asthma and Allergies in Childhood Questionnaire (ISAAC) questionnaire and the rhinoconjunctivitis QoL questionnaire (Rcq-36) to assess subjective symptoms.
