BACKGROUND Fractional exhaled nitric oxide (FENO) level is directly correlated with airway inflammation in asthma patients. The objective of this study was to define normal FENO levels in healthy Thai volunteers. METHODS This prospective cohort study was conducted in healthy Thai volunteers aged ≥5 years. Demographic and clinical data were recorded and pulmonary function test (PFT) was performed. FENO was measured using a chemiluminescence nitric oxide analyzer. RESULTS Seventy-nine healthy…

Comparison of fractional exhaled nitric oxide, spirometry, and Asthma Control Test, in predicting asthma exacerbations: A prospective cohort study
TLDR
In this study, FEV1% and ACT score could predict exacerbations of asthma whereas FeNO could not, and FeNO level correlated inversely with ACT score.
Key notes around fraction of exhaled nitric oxide marker in pneumonia
TLDR
Fractional exhaled nitric oxide could be used as a beneficial airway inflammatory marker that is related to modified PIRO score in children but cannot identify pneumonia type.
Clinical implications of concentration of alveolar nitric oxide in asthmatic and non-asthmatic subacute cough
TLDR
A low CANO value in non-asthmatic subacute cough corresponded to a higher value of RDR, which implied a stronger tendency towards airway responsiveness, which might promote understanding of the clinical utility of CANO in these special patient populations.
Exhaled nitric oxide helps discriminating asthmatic children with and without positive specific IgE to aeroallergens.
TLDR
In asthmatic children, aeroallergen sensitization appears to contribute to higher FeNO levels than those not sensitized, and cut-off values of FeNO which well discriminate astHmatic children with and without aeroAllergens sensitization should be chose according to different ages.
Nasal Irrigation: An Imprecisely Defined Medical Procedure
TLDR
Analysis of the literature showed that NI seems to be effective in the treatment of several acute and chronic sinonasal conditions, however, although in recent years several new studies have been performed, most of the studies that have evaluated NI have relevant methodologic problems.
The Impact of Exposure to Indoor Pollutants on Allergy and Lung Inflammation among School Children in Selangor, Malaysia: An Evaluation Using Factor Analysis
TLDR
A cross-sectional study of 470, 14-year-old students from 8 secondary schools located in sub-urban and urban areas in Hulu Langat district, Selangor, Malaysia was undertaken to determine the impact of climate change on students' academic performance.

Reference Values and Determinants of Fractional Concentration of Exhaled Nitric Oxide in Healthy Children
Purpose Measurement of the fractional concentration of exhaled nitric oxide (FeNO) is a quantitative, noninvasive, simple, safe method of assessing airway inflammation. While FeNO measurement has…

Exhaled nitric oxide (FENO) was proposed as a marker of airway inflammation, but data about FENO in healthy children measured with standardized methods are so far limited. In order to assess the…

Reference values of exhaled nitric oxide for healthy children 6–15 years old
TLDR
Exhaled NO levels in exhaled gas were measured by a tidal breathing method with a chemiluminescence analyzer, and NO steady‐state levels were recorded.
The predictive value of exhaled nitric oxide measurements in assessing changes in asthma control.
TLDR
It is concluded that eNO measurements are as useful as induced sputum analysis and AHR in assessing airway inflammation, with the advantage that they are easy to perform.
Normal values and thresholds for the clinical interpretation of exhaled nitric oxide levels in the US general population: results from the National Health and Nutrition Examination Survey 2007-2010.
TLDR
A large variation of normal FENO values existed in the general population, which was poorly predicted by multiple linear regression models and indicated abnormality and a high risk of airway inflammation.
A comparison of exhaled nitric oxide and induced sputum as markers of airway inflammation.
TLDR
ENO is likely to have limited utility as a surrogate clinical measurement for either the presence or severity of eosinophilic airway inflammation, except in steroid-naive subjects.

Exhaled nitric oxide concentration is affected by age, height, and race in healthy 9- to 12-year-old children.
TLDR
Feno concentrations in healthy school-aged children appeared to be affected by race, and, to a lesser extent, by age and height, and these factors should be taken into consideration when interpreting clinical results.
