It is now generally conceded that the development of tape-worms is due to the swallowing of an egg or germ-cell, which is contained in many kinds of animal food, and which the process of cooking has failed to destroy. People living near low marshes, lakes, or the seacoast, are liable to tæniæ.
Treatment. The expulsion of the ascaris lumbricoides may be very easily and pleasantly effected. Santonin is an effectual remedy for this variety of worms. For a child three years old, take santonin, six grains; podophyllin, one grain; white sugar, thirty grains; mix, triturate, and divide into twelve powders, and give one every three or four hours, until they act upon the bowels; or take santonin, ten grains; white sugar, twenty grains; mix, triturate, and divide into ten powders, and give one every night at bed-time, and after giving two or three in this way, administer a mild cathartic. As santonin is almost entirely tasteless, if not combined with other medicines which are unpalatable, no difficulty will be experienced in administering it to children. By reference to the article on anthelmintics in this volume, other valuable vermifuges may be selected, and directions found for their employment.
In the removal of thread or pin-worms, anthelmintic medicines taken into the stomach are of little or no value. An injection of a strong solution of salt, is a very efficient remedy. A teaspoonful of turpentine in half a pint of milk makes a good injection. Strong coffee has been recommended as an injection. The anus should be well anointed with vaseline, lard, oil, or fresh butter, after each movement of the bowels. Whatever injection or remedy is used, it should be followed by the application of some ointment to the anus, otherwise they will continue to deposit their eggs about that orifice and multiply there.
Various remedies have been used to destroy tape-worms. Among others we may mention the old and time-honored remedy, which consists of two or three ounces of the oil of turpentine, taken in castor oil or some aromatic tincture.
A decoction made by boiling two or three ounces of freshly powdered pomegranate bark in a pint of water was used by the ancients, and is now highly recommended as a remedy.
Some American physicians have used an emulsion of pumpkin seeds with marked success.
Twenty or thirty grains of the extract of male fern, followed by a cathartic is highly recommended for the destruction and removal of tæniæ.
TRICHINA SPIRALIS.
In 1835, Owen discovered a peculiar parasite, which sometimes infests the human body, and is termed the trichina spiralis. The presence of these parasites has given rise to morbid conditions of the system, followed by the most serious results. They are developed in the alimentary canal, and then perforate its tissues and enter the muscles. Twelve trichinæ have been found in a section of human muscle only one-twelfth of an inch square and one-fifth of an inch in thickness.
The early symptoms of trichinæ are very uncertain, being the same as those of some other disease. The patient complains of severe pain in the abdomen and is troubled with diarrhea. When the trichinæ pass into the muscles, they occasion great suffering. There are sharp pains in the muscles, the perspiration is profuse, and the patient becomes exhausted.
