The peculiar effects of a tapeworm are exaggerated appetite and thirst, nausea, headaches, vertigo, ocular symptoms, cardiac palpitation, and Mursinna has even observed a case of trismus, or lockjaw, due to taenia solium. Fereol speaks of a case of vertigo, accompanied with epileptic convulsions, which was caused by teniae. On the administration of kousso three heads were expelled simultaneously. There is a record of an instance of cardiac pulsation rising to 240 per minute, which ceased upon the expulsion of a large tapeworm. It is quite possible for the presence of a tapeworm to indirectly produce death. Garroway describes a case in which death was apparently imminent from the presence of a tapeworm. Kisel has recorded a fatal case of anemia, in a child of six, dependent on teniae.
The number of ascarides or round-worms in one subject is sometimes enormous. Victor speaks of 129 round-worms being discharged from a child in the short space of five days. Pole mentions the expulsion of 441 lumbricoid worms in thirty-four days, and Fauconneau-Dufresne has reported a most remarkable case in which 5000 ascarides were discharged in less than three years, mostly by vomiting. The patient made an ultimate recovery.
There are many instances in which the lumbricoid worms have pierced the intestinal tract and made their way to other viscera, sometimes leading to an anomalous exit. There are several cases on record in which the lumbricoid worms have been found in the bladder. Pare speaks of a case of this kind during a long illness; and there is mention of a man who voided a worm half a yard long from his bladder after suppression of urine. The Ephemerides contains a curious case in which a stone was formed in the bladder, having for its nucleus a worm. Fontanelle presented to the Royal Academy of Medicine of Paris several yards of tapeworm passed from the urethra of a man of fifty-three. The following is a quotation from the British Medical Journal: "I have at present a patient passing in his urine a worm-like body, not unlike a tapeworm as far as the segments and general appearance are concerned, the length of each segment being about 1/4 inch, the breadth rather less; sometimes 1 1/2 segments are joined together. The worm is serrated on the one side, each segment having 1 1/2 cusps. The urine pale, faintly acid at first, within the last week became almost neutral. There was considerable vesical irritation for the first week, with abundant mucus in the urine, specific gravity was 1010; there were no albumin nor tube-casts nor uric acid in the urinary sediments. Later there were pus-cells and abundant pus. Tenderness existed behind the prostate and along the course of left ureter. Temperature of patient oscillated from 97.5 degrees to 103.2 degrees F. There was no history at any time of recto-vesical fistula. Can anyone suggest the name, etc., of this helminth?"
Other cases of worms in the bladder are mentioned in Chapter XIII
Mitra speaks of the passage of round-worms through the umbilicus of an adult; and there is a case mentioned in which round-worms about seven inches long were voided from the navel of a young child. Borgeois speaks of a lumbricoid worm found in the biliary passages, and another in the air passages.
Turnbull has recorded two cases of perforation of the tympanic membrane from lumbricoides. Dagan speaks of the issue of a lumbricoid from the external auditory meatus. Laughton reports an instance of lumbricoid in the nose. Rake speaks of asphyxia from a round-worm. Morland mentions the ejection of numerous lumbricoid worms from the mouth.
Worms have been found in the heart; and it is quite possible that in cases of trichinosis, specimens of the trichinae may be discovered anywhere in the line of cardiac or lymphatic circulation. Quoted by Fournier, Lapeyronnie has seen worms in the pericardial sac, and also in the ventricle. There is an old record of a person dying of intestinal worms, one of which was found in the left ventricle. Castro and Vidal speak of worms in the aorta. Rake reports a case of sudden death from round-worm; and Brown has noted a similar instance.
The echinococcus is a tiny cestode which is the factor in the production of the well-known hydatid cysts which may be found in any part of the body. Delafield and Prudden report the only instance of multilocular echinococcus seen in this country. Their patient was a German who had been in this country five years. There are only about 100 of these cases on record, most of them being in Bavaria and Switzerland.
The filaria sanguinis hominis is a small worm of the nematode species, the adult form of which lives in the lymphatics, and either the adult or the prematurely discharged ova (Manson) block the lymph-channels, producing the conditions of hematochyluria, elephantiasis, and lymph-scrotum. The Dracunculus medinensis or Guinea-worm is a widely-spread parasite in parts of Africa and the West Indies. According to Osler several cases have occurred in the United States. Jarvis reports a case in a post-chaplain who had lived at Fortress Monroe, Va., for thirty years. Van Harlingen's patient, a man of forty-seven, had never lived out of Philadelphia, so that the worm must be included among the parasites infesting this country.
In February, 1896, Henry of Philadelphia showed microscopic slides containing blood which was infested with numbers of living and active filaria embryos. The blood was taken from a colored woman at the Woman's Hospital, who developed hematochyluria after labor. Henry believed that the woman had contracted the disease during her residence in the Southern States.
