Trich Health Dictionary

A condition in which the eyelashes become ingrown. (See EYE, DISORDERS OF.)... trichiasis

Trichinosis, or trichiniasis, is a disease caused by eating meat infected with the parasitic nematode worm, Trichinella spiralis. Although it infects more than 100 animal species, this nematode usually infects humans via pig meat in which the immature spiralis is encysted. The full-grown female worm, which inhabits the intestine, is 3 mm in length, and the larvae, to whose movements the disease is due, are much smaller. The disease is acquired by eating raw or underdone pork from pigs that have been infected with the worm. When such a piece of meat is eaten, the embryos contained in it are set free and develop into full-grown trichinellae; from each pair of these, 1,000 or more new embryos may arise in a few weeks. These burrow through the walls of the gut, spread throughout the body and settle in voluntary muscle.

Prevention is based on thorough inspection of meat in slaughterhouses; even cooking, unless the meat is in slices, is not an e?cient protection. Pigs should not be fed on unboiled garbage. Rats may be a source of sporadic outbreaks, as infected rats have been found near piggeries. The disease is widely distributed throughout the Americas, Asia, Africa and the Arctic. Sporadic cases and epidemics occur and outbreaks also appear in Europe, although rarely in Britain.

Treatment Thiabendazole or mebendazole are usually e?ective, while STEROID treatment helps patients with systemic illness and muscle tenderness.... trichinosis

The disease caused by infection with TRICHOMONAS VAGINALIS.... trichomoniasis

An obsessional impulse to pull out one’s own hair.... trichotillomania

A worldwide infection, particularly common in the tropics. It is caused by Trichuris trichiura, or whipworm, so-called because of its shape – the rear end being stout and the front end hair-like, resembling the lash of a whip. The male measures 5 cm and the female 4 cm in length. Infection results from eating vegetables, or drinking water, polluted with the ova (eggs). These hatch out in the large INTESTINE and the diagnosis is made by ?nding the eggs in the stools (FAECES). The worms seldom cause any trouble unless they are present in large numbers when, especially in malnourished children, they may cause bleeding from the bowels, ANAEMIA and PROLAPSE of the RECTUM. The most e?ective drug is MEBENDAZOLE.... trichuriasis

A genus of nematode worms which cause the zoonotic infection trichinellosis (trichinosis). Includes five species, all of which can infect humans, Trichinella spiralis, T. nativa, T. nelsoni, T. britovi and T.pseudospiralis... trichinella

DDT is the generally used abbreviation for the compound which has been given the o?cial name of dicophane. It was ?rst synthesised in 1874, but it was not until 1940 that, as a result of research work in Switzerland, its remarkable toxic action on insects was discovered. This work was taken up and rapidly expanded in Great Britain and the USA, and one of its ?rst practical applications was in controlling the spread of TYPHUS FEVER. This disease is transmitted by the louse, one of the insects for which DDT is most toxic. Its toxic action against the mosquito has also been amply proved, and it thus rapidly became one of the most e?ective measures in controlling MALARIA. DDT is toxic to a large range of insects in addition to the louse and the mosquito; these include house?ies, bed-bugs, clothes-moths, ?eas, cockroaches, and ants. It is also active against many agricultural and horticultural pests, including weevils, ?our beetles, pine saw?y, and most varieties of scale insect.

DDT has thus had a wide use in medicine, public health, veterinary medicine, horticulture, and agriculture. Unfortunately, the indiscriminate use of DDT is potentially hazardous, and its use is now restricted or banned in several countries, including the United Kingdom.

The danger of DDT is that it enters the biological food chain with the result that animals at the end of the food chain such as birds or predators may build up lethal concentrations of the substance in their tissues.

In any case, an increasing number of species of insects were becoming resistant to DDT. Fortunately, newer insecticides have been introduced which are toxic to DDT-resistant insects, but there are doubts whether this supply of new insecticides can be maintained as insects develop resistance to them.... dichlorodiphenyl trichloroethane
