Background: Small airways disease (SAD) in severe asthma (SA) is associated with high disease burden. Effective treatment of SAD could improve disease control. Reduced end-expiratory flows (forced expiratory flow [FEF]25-75 and FEF75) are considered sensitive indicators of SAD. Inhaled medication should be delivered to the smaller peripheral airway...

The tobacco industry is accountable for an annual global death toll of approximately 8 million people and cigarette smoking is the foremost risk factor for several types of cancer. In addition, the tobacco industry has a long and controversial history of trying to influence scientific research and of engaging in other morally problematic practices....

Background In adults with severe asthma(SA) airway wall thickening, bronchiectasis and low attenuation regions(LAR) have been described on chest computed tomography(CT) scans. The extent to which these structural abnormalities are present in children with SA is largely unknown. Aim To study the presence and extent of airway abnormalities on chest...

Objective: Conventional inhaler devices have a low efficacy in targeting small airways. Smart nebulizers can be used to increase deposition to small airways by adjusting the flow and depth of each inhalation based on patients 'individual inspiratory capacity. We investigated whether targeting of high dose inhaled corticosteroids (ICS) to small air...

Small airways (<2 mm in diameter) are probably involved across almost all asthma severities and they show proportionally more structural and functional abnormalities with increasing asthma severity. The structural and functional alterations of the epithelium, extracellular matrix and airway smooth muscle in small airways of people with asthma have...

Rationale: Paediatric laryngotracheal stenosis (LTS) is often successfully corrected with open airway surgery. However, respiratory and vocal sequelae frequently remain. Clinical care and surgical interventions could be improved with better understanding of these sequelae. Objective: The objective of this cross-sectional study was to develop an...

Question Which is the best strategy to achieve (drug-free) inactive disease in juvenile idiopathic arthritis (JIA)? Methods In a randomised, single-blinded, study in disease-modifying anti-rheumatic drug (DMARD)-naive patients with JIA, three treatment-strategies were compared: (1) sequential DMARD-monotherapy (sulfasalazine or methotrexate (MTX))...

Background In rheumatoid arthritis treatment, targeted treatment has shown to improve disease outcomes including the option of drug tapering and discontinuation. In non-systemic juvenile idiopathic arthritis (nsJIA) this has not been tried in a trial. Objectives To investigate which of three treatment strategies, targeting at drug-free inactive di...

With interest we read the letter of Luo, Zeng and He.1 Our recent study2 evaluated the diagnostic accuracy of the squeeze test to identify arthritis. Evidently, Luo et al are disappointed by the test characteristics and the sensitivity of the test to identify arthritis in particular; the sensitivity was around 50%.1 We completely agree with Luo et...

Objectives: In daily practice, the squeeze test is used to screen for arthritis in metacarpophalangeal (MCP) and metatarsophalangeal (MTP) joints. This cross-sectional cohort study determined the diagnostic accuracy of this test. Methods: Patients referred with arthralgia of recent onset that had either a clinical suspicion for progression to ar...
