The local condition of the throat helps in the diagnosis: In tonsilitis (as the name implies) the disease is limited to the tonsils and on the tonsils (one or both) do we find the spots or patches. In diphtheria, on the other hand, the membrane is not limited to the tonsils, but may cover every part of the throat and extend into the nose and mouth. In tonsilitis it is spots or patches we see in the throat. In diphtheria it is membrane we see always. The difficulty here again is that if we wait till the diphtheritic membrane covers the whole throat, antitoxin will not be of much use. In diphtheria we have a characteristic odor, in tonsilitis we have no characteristic odor. The practical lesson to be learned from this uncertainty is, immediately to get a physician as soon as you find spots in the throat of your sick child, unless you are absolutely sure that the condition is not diphtheria and you are willing to take that chance. Treatment of an Acute Attack of Tonsilitis.--Put the child in bed at once and keep him on a light diet during the fever. Give him all the cool boiled water he wants to drink. If the fever is very high it can be controlled by sponging the body with cool water. If the patient is an infant the food should be reduced to one-half strength. Tonsilitis is a disease that runs a certain course and gets better, or the patient develops some other more serious conditions as a result of neglect or carelessness. We therefore try to make the patient comfortable and let the disease take care of itself. The throat can be gargled or sprayed with any mild antiseptic liquid, or it can be painted with tincture of iodine or 10 per cent. solution of silver nitrate. As a rule the gargles do not aid in the cure of the disease, though they contribute to the comfort of the patient. A cold compress made of half a dozen thicknesses of cloth, such as a table napkin, and put under the jaw (not round the neck), and covered with oiled silk and held in place with a bandage that meets and is tied on the top of the head, is of distinct usefulness. When it is known that the child is rheumatic, the heart must be carefully watched during the fever and anti-rheumatic remedies depended upon to effect a cure. SUMMARY:-- Tonsilitis, because of its likeness to diphtheria, must be promptly and carefully diagnosed. A physician only is capable of making a diagnosis. Any sore throat in a child with spots or membrane is deserving of serious and immediate attention. A mistake may mean death. Don't take a chance. BRONCHITIS
