A new definition and treatment options of allergic alveolitis.

In this review, we discuss a new definition and treatment options of allergic alveolitis (AA). AA is an immune-mediated interstitial lung disease triggered by inhaled antigens, it is defined as non-fibrotic (inflammatory) and/or fibrotic, and diagnosis relies on a multidisciplinary approach using clinical, radiological and sometimes histological assessments. Treatment involves early antigen elimination and may include corticosteroids or other immunosuppressants. Prognosis varies from reversible inflammation to irreversible fibrosis. Early detection is crucial for better outcomes.

Identification and management of interstitial lung abnormalities.

Interstitial lung abnormalities (ILA) are incidentally observed specific CT findings in patients without clinical suspicion of interstitial lung disease (ILD). ILA with basal and peripheral predominance and features suggestive of fibrosis in more than 5% of any part of the lung should be referred for pulmonologist review. The strategy for monitoring as described in this review is based on clinical and radiological risk factors. ILA are associated with risk of progression to ILD and increased mortality. Early identification and assessment of risk factors for progression are essential to improve outcome.

[Cocaine-induced asthma exacerbation].

Asthma is one of the most common chronic diseases in children and adults. Cocaine is associated with asthma exacerbations. In Denmark, the prevalence of cocaine use has been increasing in recent years. This is a case report of a 47-year-old male with acute asthma exacerbation after cocaine use. Cocaine use is probably an underestimated reason for acute asthma exacerbations.
