2nd. It is called "false" croup, because "true" croup is always diphtheritic and is a very serious disease. 3rd. For that reason a physician should always be called because if it is "true" croup antitoxin must be given at once. 4th. Don't worry unnecessarily because, though "spasmodic croup" can make the child look exceedingly sick for a very short time, an uncomplicated case in a healthy child is seldom if ever dangerous. TONSILITIS: ANGINA: "SORE THROAT" This is one of the frequent diseases of childhood. We rarely see it in infants. It is caused by inhaling air which contains poisonous germs. These germs quickly develop when conditions are favorable. They lodge in the pores or follicles of the tonsils and set up an active inflammation. The tonsils swell up and the follicles exude a thick fluid which looks like curdled cream. This fluid sticks in the mouths of the follicles forming spots. If enough of this fluid is coming out, these spots join together forming patches, and the patches may join together forming membrane. This is why it is sometimes so difficult to tell whether the case is one of tonsilitis or diphtheria. Conditions are favorable to the development of tonsilitis if the child is not in good health when he happens to inhale the infection, when the feet are wet or cold, or when the child is allowed out during inclement weather and it becomes chilled or numbed from cold, when the child has a cold in the head and a running nose, or when its stomach is out of order. Any condition in which the child should be carefully watched and tended to, rather than allowed further liberties, or risks, conduces to sore throat of some kind. Some children have the disease a number of times; they seem to be predisposed toward a sore throat. These are children who have large tonsils or who are rheumatic. The tonsils should be removed in the one case, and the tendency to rheumatism should be the main treatment in the other case. These children should be encouraged to cleanse the throat and nose morning and night with a warm salt solution (half a teaspoonful of ordinary table salt to three-quarters of a cup of warm water). This will help greatly to prevent these chronic sore throats. Symptoms of Tonsilitis.--The disease begins suddenly. The child may have a chill or be seized with sudden vomiting or diarrhea. A very young infant may have a convulsion. The usual way is for the child to develop a fever quickly, to complain of being sick and tired. Muscular pains all over the body and a severe headache are constant symptoms. The fever is usually high from the beginning. The child will tell you its throat is sore, but there is as a rule very little pain in the throat. The little spots or patches can be seen on one or both tonsils. The general symptoms are more pronounced than the local throat symptoms. The amount of physical depression that is caused by a tonsilitis is out of all proportion to the seriousness of the disease.
