Sinusitis and chronic cough in children.

Background: Chronic cough in children is a common problem, and sinusitis is a common etiology. The diagnosis of sinusitis is often clinical, but confirmation is thought to require a CT scan due to the difficulty of interpreting a Water's view sinus X-ray.

Objectives: The purposes of the study were (1) to examine the frequency of an abnormal sinus X-ray in children with a chronic cough of more than 4 weeks duration; (2) to compare the interpretation of the sinus film between allergy/pulmonary clinicians and radiologists; and (3) to correlate symptoms with X-ray results.

Skin barrier function and its importance at the start of the atopic march.

Atopic dermatitis can be due to a variety of causes from nonatopic triggers to food allergy. Control of egress of water and protection from ingress of irritants and allergens are key components of cutaneous barrier function. Current research suggests that a degraded barrier function of the skin allows the immune system inappropriate access to environmental allergens.

Early Pollen Sensitization in Children Is Dependent upon Regional Aeroallergen Exposure.

Introduction. Aeroallergen sensitization occurs at an earlier age than previously noted. The purpose of this paper was to identify which pollens cause early sensitization in young children presenting with rhinitis symptoms.
