ReviewFood protein-induced enterocolitis syndrome and allergic proctocolitis.
Non-IgE-mediated food allergic disorders account for up to 40% of milk protein allergy in infants and young children. We aim to review the recent literature and to provide an update on diagnosis and management of food protein-induced enterocolitis syndrome (FPIES) and food protein-induced allergic proctocolitis (FPIAP). The peer-reviewed articles indexed in PubMed have been reviewed. ⋯ The majority of cases resolve by age 12 months. FPIES may transition to IgE-mediated food allergy in some patients; IgE positivity to the FPIES food is a marker of a more persistent disease. FPIAP is benign and resolves by age 12 months in most patients.

Effect of breastfeeding on the protective effect on asthma has been studied extensively but remains controversial. Studies regarding the effect of breastfeeding on lung function have also been conflicting. The aim of this study was to determine the influence of breastfeeding on lung function in asthmatic children. ⋯ Increase in FEV1/FVC was seen in the exclusive breastfeeding for ≥6 months group compared with those partially breastfed but FVC was significantly lower in those exclusively breastfed <6 months group compared with those partially breastfed. BDR decreased with breastfeeding duration in the nonatopic asthma group. In conclusion, longer duration of breastfeeding appears to have a favorable effect on lung function in asthmatic children, especially in nonatopic subjects.

Angioedema is swelling of the deep layers of the dermis and subcutaneous tissue due to an increase in vascular permeability. Angioedema sometimes occurs concomitantly with urticaria and represents an allergic disease. ⋯ After detailed history, physical examination, and laboratory evaluation, a cause for her angioedema was found that had not been considered previously and had significant implications for future management, particularly in light of her current pregnancy. Because allergists are commonly called on to evaluate and treat angioedema, we should be aware of the many disease processes that can present with this symptom and be well-versed in the workup of new-onset angioedema.

ReviewThe chronic obstructive pulmonary disease-asthma overlap syndrome.
When asthma and chronic obstructive pulmonary disease (COPD) occur together the term COPD-asthma overlap syndrome has been applied. To date, there is no universally accepted definition of this overlap syndrome, just as there is no blood test or other technologic assessment that provides a simple way to distinguish asthma from COPD. ⋯ Compared with patients with COPD alone, the overlap patients are younger with less smoking intensity, have higher health-care utilization, have a worse disease-related quality of life, and have a higher mortality. Treatment with corticosteroids earlier in the course of the disease compared with the patient with only COPD has been recommended.
