Comprehensive pulmonary rehabilitation according to severity of COPD.
A new classification for the severity of COPD was proposed at GOLD 2003: stage I: FEV(1) > or = 80% predicted; stage II: 50% < or = FEV(1)<80%; stage III: 30% < or = FEV(1)<50%; and stage IV: FEV(1) < 30%. To elucidate the acute effects of pulmonary rehabilitation (PR) on patients with different stages of COPD, data on pulmonary function, arterial blood gas analysis, the 6-min walk test, respiratory muscle strength, and activities of daily living were analyzed before and after our comprehensive 4- to 8-week inpatient PR program between 1992 and 2003. A total of 225 patients (201 men and 24 women; 21 with stage II, 79 with stage III, and 125 with stage IV COPD) was assessed. ⋯ Activities of daily living were significantly improved in all stages. These results showed that patients with COPD had benefited from PR regardless of disease severity. The effects included improvement in pulmonary function, arterial blood gas analysis, 6-min walk distance, respiratory muscle strength, and activities of daily living although there were some differences among the three stages.

Rabbit allergens: a significant risk for allergic sensitization in subjects without occupational exposure.
Although rabbits are becoming popular as pets, data about the characteristics of allergic sensitization to rabbit allergens in patients without professional exposure are scarce. ⋯ In susceptible not professionally exposed individuals, direct rabbit contact and, in some cases, indirect or no apparent exposure, may induce allergic sensitization to rabbit allergens. A progressive increase in rabbit sensitization (also by indirect exposure) may be expected as a consequence of the increase in rabbit ownership.
