Abstract
SummaryThe lungs of 103 unselected subjects were examined for emphysema by a variety of methods to study the frequency and severity of the types of emphysema common in an Australian community. A closer study was made of those from 80 subjects aged 51 to 80 years at death, and in particular of the 49 men in this group.It was found that emphysema was much more common among men than among women, and it is most desirable that the findings for the two sexes be kept separate in future studies.In both men and women the centrilobular type was most common. Most men with panacinar emphysema also had centrilobular emphysema; but most men with centrilobular emphysema did not have panacinar emphysema. The significance of this is not apparent. It was rare for a man to have one type of emphysema alone.At death, acute bronchiolitis and bronchopneumonia were not more common in those subjects with emphysema, an observation which lends no support to the theory that acute bronchitis is a common cause of emphysema.
