The Symptoms of Thread-Worm or Oxyuris Vermicularis Infection

Severe itching and tickling just within the anus, especially at night; unnatural sexual excitement; in males, frequent erections, and even seminal emissions; presence of the worms in the bowel passages.

Many other symptoms have been attributed to the presence of this worm, but the above are the most important. Contrary to the generally received opinion, the worm does not inhabit chiefly the rectum, but the large intestine, and especially the caecum. Its natural size may be seen by reference to Fig. 285. In Fig. 286 is seen the worm greatly magnified and in the act of shedding its skin. The symptoms in the rectum are produced by the motions of the worms in this part, as they go down into the rectum to deposit their eggs. Sometimes they crawl out upon the skin about the anus, but in such cases soon die, as they cannot return.

The Cause of Thread-Worm or Oxyuris Vermicularis Infection

The thread-worm is undoubtedly produced from eggs, which each worm produces in prodigious numbers. How they get into the stomach is not well known, but it is undoubtedly through neglect of proper cleanliness.

The Treatment of Thread-Worm or Oxyuris Vermicularis Infection

All the text-books prescribe treatment for the rectum; but this mode of treating the disease has been notoriously unsuccessful. The treatment, in order to be of any real value, must reach the large intestine and especially the caecum. According to Heller, the best remedy is a copious enema of water, or of a solution of castile soap in proportion of a dram of soap to a quart of water. From two to four quarts of water should be injected into the bowels at once. A handful of quassia chips may be boiled in the water instead of using soap. The remedy usually requires repetition for a few times. We have found it successful when thoroughly applied.
