The topics chosen for discussion represent the most common problems
referred by family doctors to chest clinics. It was taken for granted
that the reader will be familiar with the symptoms, signs, and natural
history of respiratory diseases, so that the stress is on differential
diagnosis and treatment. Tuberculosis once occupied nearly all the time
of chest physicians. At present weeks go by without a single case
presenting itself. There has been no comparable improvement in cancer of
the lung, which remains one of the most intract- able problems. Asthma
was seldom referred to out-patient clinics when the disease was regarded
as more unpleasant than dangerous. The hazards of severe attacks and the
advan- tages of liaison with a hospital department are now widely
recognized. A similar change of attitude to the management of chronic
bronchitis brought many new patients to the chest clinics in place of
the vanishing tuberculous population. Some uncommon pulmonary diseases
are included: allergic alveolitis, because of the importance of early
diagnosis, and sarcoidosis in order to discourage unnecessary treatment.
The book is intended to be a practical guide and is not a critical
review. This might serve as an excuse for its didactic style and the
exclusion of controversial subjects. Some statements are repeated at
more than one place in order to help readers who wish to consult
individual chapters bearing on some current problem. Source references
are omitted and are replaced by a short list of books recommended for
further reading.
