The feasibility of studying respiratory symptoms and lung function on a cohort basis from adolescence onwards has been examined by a study of a group of 102 medical students on entry to their course. In the present paper the results from the initial examination and from a second, four years later, are reported. Up to that time smoking habits were light, and there was very little change in any o...

Functional loss (often quantified as exercise limitation) is common in patients with chronic lung disease. The factors involved are multiple and many may be present together in a given patient. Ventilatory factors involve an imbalance in load/capacity relationships. Specifically, breathing loads from abnormal respiratory-system mechanics and/or excessive ventilatory demand cannot be handled by ...

BACKGROUND Pneumonectomy is associated with higher early mortality and morbidity, and it is also known to predispose the patient to respiratory complications during mid- and long-term follow-up. Therefore, the purpose of this study was to identify risk factors associated with respiratory complications during the follow-up period after pneumonectomy. METHODS We retrospectively reviewed 98 pati...

A prospective cohort study was conducted to estimate the incidence of acute respiratory infections (ARI) among hajjis registered at primary health care centres of Riyadh. Out of 1027 hajjis, 39.8% developed symptoms of ARI. The incidence of ARI was not statistically significantly associated with age, sex, educational status or smoking.
