ANIMAL PARASITES ATTACKING IRRITATING OR PENETRATING SKIN



Treatment of this formation is by free incision and pressure followed by applications of an antiseptic to the wound. In migrating or serpiginous forms, the larvae may be secured by excising or cauterizing the area around or beyond the spreading lesion. The cataphoretic application of mercuric chlorid, 2 grains to the ounce, has been recommended.

CRAW CRAW

This is a condition observed chiefly upon the west coast of Africa in which both nematodes and filaria have been found. It resembles scabies in attacking the fingers and forearms and presents itching vesicles, papules and pustules. Excoriations and crusting results from scratching, but the typical burrows, distribution and history of scabies are absent. Treatment involves cleanliness and the use of parasiticides but the diseases is often persistent and rebellious.

ECHINOCOCCUS

The larvae of this tinea have been found in the human skin as encapsulated soft tumors and vesicles which produce a sensation of tension and undergo a fatty or calcareous degeneration after the death of the parasite. Extirpation is the only treatment.

DISTOMA HEPATICUM

The embryos of the large liver-fluke have given rise to encapsulated tumor-like formations in the subcutaneous tissues of human beings in three reported instances. The distoma must be found to establish a positive diagnosis.

UNCINARIA DUODENALIS

This intestinal parasite and similar varieties belonging to the nematode family, Strongylidae, are principally interesting as the cause of the so-called hookworm disease. It was formerly thought that its larvae found entrance through the mouth in food or water, but it is now known that a common form of entrance is by means of the skin of the feet and legs. Here erythematous, papular, vesicular or bullous eruptions may be found. It is intensely itchy and is often first noticed between the toes. Clean linen, mild antiseptic or antiparasitic ointments or lotions are indicated for the skin lesions. Prophylaxis is a most important item of treatment.

TRYPANOSOMA GAMBIENSE

This and similar minute flagellate parasites which invade the body by means of an insect (the common fly, Glossina palpalis, or the tsetse fly) acting as host, cause a disease known as trypanosomiasis or in its advanced stages “sleeping sickness.” The puncture made by the insect referred to, may cause a deep red furunculoid swelling, followed by pigmentation. As the constitutional symptoms become more pronounced, so the cutaneous aspect changes and new lesions appear. Prophylaxis, protection against the insects, is the most important point in treatment. Locally antiseptic and antiparasitic lotions may be used. Arsenic is the mainstay of internal medication.
