Asthma from the patient's perspective.

Background: Asthma is a chronic disease with considerable burden on health and economy. Despite growing knowledge about causes and treatment, many patients have uncontrolled asthma, activity and social limitations and reduced quality of life (QOL). Coping with asthma could be developed in a social and scientific context and influenced by personal experience.

Factors influencing quality of life in asthmatics--a case-control study.

Introduction: The quality of life (QOL) in persons with asthma is reduced and different factors such as demography, asthma severity and psychiatric comorbidity play an influential role. However, little is known about the interplay of these factors.

Objective: To describe QOL in relation to asthma and analyse for the relative impact of asthma severity, psychiatric comorbidity, lifestyle (smoking and obesity) and demographic determinants on QOL in persons with asthma.

Chronic rhinosinusitis and occupational risk factors among 20- to 75-year-old Danes-A GA(2) LEN-based study.

Background: Very little is known about occupational risk factors for chronic rhinosinusitis (CRS). The aim of this study was to evaluate occupational and other potential risk factors for CRS in a Danish population.

Methods: A cross sectional survey study among 4,554 Danes aged 20-75 years evaluated self-reported symptoms of CRS, asthma, and nasal allergy, along with information on smoking habits and occupation.

The Sino-Nasal Outcome Test 22 validated for Danish patients.

Introduction: Chronic rhinosinusitis (CRS) is a significant health problem whose incidence and prevalence is rising. It calls into attention consensus about diagnosing, assessing symptoms and treatment of patients with CRS. Therefore, a validated Danish measure of health-related quality of life in sinonasal disease is needed.
