ReviewQuality of life in food allergy: valid scales for children and adults.
The purpose of this review is to give an overview of how health-related quality of life (HRQL) can be measured in food allergy and to explore recent findings on how food allergy might impact HRQL. ⋯ Assessment of HRQL could be used by clinicians to get insight into the specific problems patients have to face. In addition, HRQL measurements may be used to measure the effects of an intervention on the patient's quality of life. Finally, HRQL is the only available measure reflecting the ongoing severity of food allergy, as no objective disease parameters are available.

ReviewChildhood asthma may be a consequence of vitamin D deficiency.
Vitamin D deficiency has been rediscovered as a public-health problem worldwide. It has been postulated that vitamin D deficiency may explain a portion of the asthma epidemic. The purpose of this review is to present the evidence for a role of vitamin D in asthma. ⋯ Improving vitamin D status holds promise in primary prevention of asthma, in decreasing exacerbations of disease, and in treating steroid resistance. However, the appropriate level of circulating vitamin D for optimal immune functioning remains unclear. Because vitamin D deficiency is prevalent even in sun-replete areas, clinical trials are needed to definitively answer questions about the role of vitamin D in asthma.
