Background: Asthma is now the most frequent occupational lung disorder in Europe and North America. The condition is under-recognised, underestimated and poorly managed in Norway as well as internationally.
Material And Method: The paper is based on the author's work on occupational asthma over some years and on a search (restricted to authors with a Norwegian address) in PubMed and EMBASE in May 2007.
Results: In Norway, occupational asthma is most frequently reported for bakers, spray painters, welders, sheet metal workers, hairdressers, farmers, nurses, cleaners and workers in the aluminium industry, i.e. occupations exposed to mixtures of dust, fume, gas and vapour. Up to 70 % of asthmatics have symptoms at work that improve on absence from work. The Labour Inspection Authority was only informed about such disease for 15 % of asthmatics.
Interpretation: People with allergic occupational asthma must be relocated to prevent the disease from becoming chronic. With non-allergic asthma one can try to adapt the work environment and follow up closely. The substantial underreporting of occupational asthma is probably caused by doctors having too little knowledge of occupational medicine.

This part reviews the management of chronic cough and proposes a management algorithm. Despite proven improvements in quality of life following chronic cough treatment, a clear understanding of the disease and the evidence for the efficacy of some treatments remain vague. Eight key questions regarding the treatment in the uncertain areas were systematically addressed based on the PICO framework and applying the GRADE system for evidence synthesis to provide the strength of recommendation and quality of evidence for key questions, with narrative components for the description of other chronic cough treatment including non-pharmacological therapy.

Chronic cough is a common clinical condition requiring comprehensive assessment. This review employs a symptom-focused approach, prioritizing the presenting symptom of "chronic cough" to mirror real-world clinical practice. Ten key questions regarding the investigations in the uncertain areas were systematically addressed based on the PICO framework and applying the GRADE system for evidence synthesis to provide the strength of recommendation and quality of evidence for key questions.

Introduction: Asthma is one of the severe respiratory diseases and affects the health of people globally. Animal studies have found that the mucin 5ac(Muc5ac) levels in the lung are associated with asthma. This paper aimed to systematically evaluate the relationship between Muc5ac levels in lung and asthma by extracting relevant data from animal experiments.

Adverse effects on the respiratory system were associated with intensive petroleum-related industrial activities. The study aimed to assess the impact of petrochemical exposure on childhood asthma using various surrogate indices. A singleton birth cohort from 2004 to 2017 was conducted, leveraging two linked nationwide databases in Taiwan.
