Symptoms.--The chief symptom is itching. It may be limited to the anus or it may involve the neighboring parts. Thread-worms may find their way out of the anus and in female children may find their way into the vagina. In these instances the child is tormented with itching of the privates and may establish the habit of self-abuse as a result of the constant itching and scratching. The itching is more intense at night soon after the child goes to bed. As a result of the local irritation in the lower part of the bowel and rectum there is set up a catarrh of the bowel which produces large quantities of mucus. Treatment.--The only medication by the mouth that is of any use is turpentine in one drop doses after meals, given in a teaspoonful of sugar. The best treatment, and in most cases the only treatment that is effective, is the use of rectal injections. The procedure is as follows:--The child first gets a cleaning injection of two quarts of warm water into which a teaspoonful of borax has been put. This will wash away any mucus or fecal matter that may have collected. This injection is best given with a No. 18 rectal catheter which is pushed into the rectum for about 10 inches, the water being allowed to run away as it enters. From six to eight ounces of the infusion of quassia is then passed, as high up as the catheter will reach. It is intended that the quassia will remain in as long as possible, for at least half an hour. In order to assure this there are two features that should be kept in mind: first, the water should be allowed to flow in slowly, consequently hold the bag low, not higher than two feet above the level of the bed on which the patient lies; second, after the water is all in remove the catheter very slowly and keep the child absolutely quiet. This treatment is repeated every second night for a week, then twice a week for four weeks. A solution of garlic is a very effective remedy and may be tried if the quassia fails, which is not likely if the treatment is carried out effectively and if the parts are kept scrupulously clean. Tape Worms.--Tape worms are obtained from eating raw meat, pork or sausage, rarely from fish, and from playing with cats and dogs. Symptoms.--No definite symptoms accompany the presence of tape worm. The children may have pains in the abdomen, diarrhea, a capricious appetite, foul breath, and they may suffer from anemia, sometimes quite severely. The only positive symptoms is the presence of links of the worm in the stools. Treatment.--Give a dose of castor oil at bed time. Two hours after breakfast next morning give one-half dram of the oleoresin of male-fern in emulsion or capsule. Very light nourishment should be taken during the day, composed of gruels and soups. When the worm is passed it should be examined to find if the head is present; if not, the treatment should be repeated in twenty-four hours. RUPTURE
