Abstract Food allergy represents an increasing health problem, with children being the most affected population. The symptoms can appear within minutes or hours of ingesting the offending food, producing skin manifestations, respiratory, gastrointestinal and anaphylactic reactions in the severe forms. Food allergy is established by the loss of tolerance to food proteins, and is characterized by an altered balance of regulatory T (Treg) cells and the shift to Th2 type cytokines in the intestinal lamina propria. We have described the contribution of different factors in establishing oral tolerance, such as the antigenic exposition route, the gut microenvironment, and the timing of the food introduction. Apart from avoiding the food, immunotherapy is the only intervention which prod...

Purpose of review: To highlight the state of the art and the current outlook on the adherence to treatment in asthma, starting from the ‘Manifesto on Adherence to asthma treatment in respiratory allergy’ endorsed by the World Allergy Organization, Allergic Rhinitis and Its Impact on Asthma and Global Allergy, Asthma European Network, and Interasma. Recent findings: Adherence to the pharmacological treatments of asthma is known to be low: about 50% of those who had been prescribed long-term treatment are nonadherent, at least part of the time. Nonadherence is associated with lack of asthma control, poor health outcomes, and increased costs. The reasons for suboptimal adherence are multifaceted and may be related to the patients, the treatment and asthma features, the physician–patient...

Skeletal muscle dysfunction and physical inactivity are two clinically important features of a wide range of acute and chronic respiratory conditions. Optimisation of both of these features is important in order to improve physical function, prevent clinical deterioration and maximise community participation. One of the most potent and evidence-based interventions to address these physical deficits is pulmonary rehabilitation (PR). Whilst the majority of PR research has been conducted in patients with chronic obstructive pulmonary disease, there is widespread recognition that PR can benefit many other respiratory patient groups. These include patients with interstitial lung diseases, asthma, pulmonary hypertension, pre-/post-lung surgery (e.g. lung cancer, transplantation) and cystic fibro...

Abstract
PURPOSE OF REVIEW: New technologies continue to be introduced into the workplace and the environment. These novel technologies also bring in new hazards leading to evolving patterns of established occupational and environmental diseases, as well as novel conditions never before encountered.
RECENT FINDINGS: Many of these emerging conditions have appeared in media outlets or in the literature as case reports. These sentinel cases often serve as a warning sign for subsequent outbreaks. This review will discuss environmental and occupational lung diseases and exposures from a global perspective. These diseases and exposures include environmental exposure to asbestos and lung diseases, accelerated silicosis in sandblasting jean workers, coal worker's pneumoconiosis in surface coal miners, health effects of indoor air pollution from burning of biomass fuels and exposures to heavy metals and potential health effects from hydraulic fracturing (fracking). Other emerging conditions are also discussed, including smog in developing countries, sand storms in Asia and the Middle East and respiratory illnesses from nanoparticles and man-made fibres.
SUMMARY: Clinicians must remain vigilant for potential occupational and environmental exposures, especially when evaluating patients with unusual and unique presentation, so that occupational and environmental risk factors may be identified, and monitoring and preventive measures can be implemented early.
