Frequently when whooping-cough intervenes during the time of teething, the irritation of the gums somewhat abates. Some children have whooping-cough and diarrhœa for some length of time, and upon recovery, show quite a number of teeth. I am not all in favor of encouraging any increased discharge from the bowels, but sometimes in congestive whooping-cough a little looseness is beneficial. Cholera often sets in just as the teeth have begun to break through the gums. The treatment, however, should be the same as if not teething. Great caution should be observed not to administer drugs containing laudanum; for by so doing, air and mucus collect in the air or bronchial tubes, inducing a stoppage in the breathing. Possibly suffocation and death have resulted from this cause in numbers of cases. Whooping-cough, if gently treated, seldom, if ever, proves fatal. I have had patients under my charge with it from four weeks old, upwards. It would, nevertheless, be well to keep the tender infant from exposure to whooping-cough for a while. It does seem as if sooner or later in life we are to encounter these peculiar complaints. The main thing to do to relieve the force of whooping-cough is to keep the chest and air-tubes warm, and, most of the time, moist. If there is danger of congestion, a warm poultice of flaxseed meal spread over the chest and throat, and keeping clear of dust, smoke, or smells of any kind, will aid much. By all means the nose should be kept running, which may be done by sweating the forehead and nose. Bronchitis or wheezing, like whooping-cough, is a disease that affects the air-tubes in a greater or less degree, the inflammation sometimes becoming very distressing. The treatment should be about the same as for whooping-cough. PNEUMONIA.
