Chronic diffuse infiltrative lung disease encompasses a wide variety of disorders that primarily affect the alveoli and lung interstitium; involvement of the airways and the pulmonary vasculature is secondary to the interstitial process. Chronic diffuse infiltrative lung disease affects a surprisingly large proportion of the population. A study from New Mexico suggests a prevalence of 81 cases ...

Following the cloning of the cystic fibrosis (CF) gene, in vitro studies rapidly established the feasibility of gene therapy for this disease. Unlike ex vivo approaches that have been utilized for other genetic diseases such as adenosine deaminase deficiency, gene therapy for CF will likely require direct in vivo delivery of gene transfer vectors to the airways of patients with CF. Hence, major...

agnosed children and adults, respectively, were: 13 and 15 times greater for acute respiratory infection; 6 and 9 times greater for otitis media; 6 and 8 times greater for asthma; 6 and 12 times greater for upper respiratory infection; 5 and 8 times greater for conjunctivitis; 5 times greater (both children and adults) for chronic obstructive pulmonary disease/allied conditions; 5 and 8 times g...

Rhinitis and asthma are often associated and the two disorders interact at various levels. Rhinitis typically precedes the development of asthma and can contribute to unsatisfactory asthma control. The presence and type of asthma is influenced by sensitization, and the duration and severity of allergic rhinitis. Nasal symptoms, airflow and markers of inflammation directly correlate with lower a...

OBJECTIVES Whereas accumulating evidence indicates close associations between rhinitis and asthma, little is known about the relationships between occupational rhinitis (OR) and occupational asthma (OA). This study analyses the prevalence of OR associated with OA, globally and according to the various causal agents, and investigates the temporal relationships between these two conditions. MET...

BACKGROUND The nose and the bronchi belong, in anatomical and physiopathological terms, to the concept of united airways. Associations between upper and lower airways diseases have been demonstrated in allergic rhinitis and asthma, nasal polyposis (NP) and asthma, chronic rhinosinusitis (CRS) and chronic obstructive pulmonary disease, and more recently CRS/NP and bronchiectasis (BQ). OBJECTIV...

Allergy is the result of a complex interaction between genetic background and environmental factors, including exposure to allergens and lifestyle. Migration is a process that involves many radical changes in the environment, including diet, pollutants, allergens, different housing conditions, and patterns of infections. Thus, studies in immigrants may provide important information about the ro...
