Sinonasal Symptoms in COPD: Burden and Associations with Clinical Markers of Disease.

Purpose: Sinonasal symptoms are prevalent in COPD, and knowledge of the relationship between these symptoms and clinical markers of COPD is limited. This study explores the associations between the burden of sinonasal symptoms and clinical markers and thresholds recommended for guiding treatment decisions in the GOLD guidelines.

Patients And Methods: Sinonasal symptoms were quantified with the rhinological subscale of the Sino-Nasal-Outcome-Test (SNOT-22) in 93 COPD patients characterized by the European Position Paper on Rhinosinusitis and Nasal Polyps (EPOS) 2012 diagnostic criteria for rhinosinusitis without nasal polyps (RSsNP).

Rhinosinusitis without nasal polyps is associated with poorer health-related quality of life in COPD.

Rhinosinusitis without nasal polyps (RSsNP) is prevalent in COPD. Previous studies on its association with health-related quality of life (HRQoL) have limitations, and RSsNP is currently not recognized as a comorbidity. This study investigates HRQoL in COPD including a focus on RSsNP.

Rhinosinusitis without nasal polyps in COPD.

The validity of the united airway disease concept for rhinosinusitis (RS) and chronic obstructive pulmonary disease (COPD) has been questioned because of methodological limitations in previous studies. In this study we investigated the prevalence of RS without nasal polyps (RSsNP) and the severity of sinonasal symptoms in COPD and a corresponding control group. We also evaluated the diagnostic accuracy of these symptoms for RSsNP in COPD.

Nasal flow, volumes, and minimal cross sectional areas in asthmatics.

Background: The Unified Airways hypothesis suggests an involvement of the upper airways in asthma. Critical parameters of the nasal airway can be quantified objectively with acoustic rhinometry (AR) and peak nasal inspiratory flow (PNIF).

Objective: We aimed to investigate nasal airway patency in asthmatics compared to non-asthmatic controls.

Sino-nasal characteristics in asthmatic patients.

Objective: The Unified Airways Hypothesis suggests an involvement of the upper airways in asthma. We aimed to evaluate the association between subjective sino-nasal complaints, nasal air flow, and sino-nasal quality of life (QOL) in patients with asthma compared with nonasthmatic subjects.

Study Design: Case-control study.

Nose- and sinus-related quality of life and GERD.

Though some data indicate an association between gastroesophageal reflux disease (GERD) and upper airway inflammatory disease, a connection between GERD and chronic rhinosinusitis (CRS) is a matter of controversy in today's medicine. The aim of this study was to examine whether patients with GERD have a different nose- and sinus-related quality of life compared to a control group. A total of 77 patients with GERD diagnosed by gastroscopy were evaluated according to their nose- and sinus-related quality of life.

Occupational rhinitis: diagnostic criteria, relation to lower airway symptoms and IgE sensitization in bakery workers.

Conclusions: The use of different diagnostic criteria has considerable consequences for the prevalence estimates of occupational rhinitis. There is a strong relationship between occupational rhinitis and lower airway symptoms. Storage mites appear to be important occupational allergens in Norwegian bakeries.
