Lice infestation should be treated with 1% permethrin followed by treatment of immediate family members and sexual partners. Bedding and clothes should be sterilized by washing in the hot cycle of the washing machine. 

A parasite that lives outside the body of the host is called an ectoparasite. Approximately 6 to 12 million subjects become infested with pediculosis (lice infestation) yearly in the United States. Pediculosis is usually associated with poor hygiene, and infections are passed from person to person through social and sexual contact.

Detection of head lice infestation is based on identifying lice by detection combing. Head lice detection cannot be solely based on an itchy scalp because not all children with head lice have the symptom. Furthermore, itchiness is caused by an allergic reaction to the lice, which may develop a few weeks after the infection and can persist for some time after eradication. Infestation is equally likely to occur in clean or dirty hair. 

Turpentine, the pleasantly smelling piney solvent, gets its name from the Greek word for the tree from which turpentine was distilled. As a solvent, turpentine has medical uses to treat wounds, to combat lice infestation and as an inhalant (the well-known Vick s vapom rub used to contain turpentine). Turpentine is a mixture of 10 carbon hydrocarbons (C,o), and the composition varies depending on the tree species (usually a pine or balsam) from which it has been distilled. It was recognised that a family of Cjo terpenes... 

The volatile oil in aniseed provides the basis for its internal use to ease griping, intestinal colic and flatulence. It also has a marked expectorant and antispasmodic action and may be used in bronchitis and in tracheitis, where there is persistent irritable coughing, and to reduce the symptoms of whooping cough. Externally, the oil may be used in an ointment base for the treatment of scabies and lice infestations. Aniseed s mild oestrogenic effects, thought... 

Are the bodies shown those of victims of gassing or of a typhus epidemic Anyway, the fact that the smoke wallows along ground level shows that there is no height to a pyre and air photos show no pits.41 Thus it might be that this photo simply shows the burning of lice infested clothes of inmates who died of typhus.

As mentioned earlier, pyrethrum is an extract from chrysanthemum flowers which contains a mixture of natural compounds including pyrethrins. Pyrethrin powder has been used for many years as an insecticide in domestic applications. Com-poimds having similar structures and properties have now been synthesized as pyrethroids which are cheaper than natural pyr-ethrums and more potent. They are even more effective in treating sea lice infestations on solomon and other sea water flsh. 

Gasoline, then an insignificant petroleum by-product—often simply burned off as waste during the production of kerosene for lamps—was sold in small bottles to treat lice infestations in children s hair.

Documented effects In modem medicine a decoction of the stems and leaves is used in medicine to disinfect animals. Finely ground seeds mixed with butter is used to treat pediculosis (lice infestation). Tablets of condelphine are used to treat psycho-neurological diseases. The compounds delsemine and mellictine are used as anesthesia during surgical procedures (Altimishev 1991). The alkaloid condelphine has an activity similar to curare. Physicians use tablets of 0.025 g to treat conditions of excess skeletal muscle contraction, Parkinson s disease, multiple sclerosis, spastic and traumatic paralysis, etc. This preparation cannot be used by patients with conditions of reduced muscle contraction, liver and kidney diseases, or heart decompensation (Khalmatov et al. 1984).

FIGURE 4.3.2.1 DDT and Its Metabolites. DDT was a widely used and effective pesticide employed to treat body lice infestations and to prevent the spread of malaria. However, its persistence in the environment and its damage to the ecosystem led to its ban in many places, including the United States. 

The pyrethrins represent a group of six closely-related monoterpene esters and are invaluable insecticidal substances isolated from pyre-thrum flowers, such as Chrysanthemum cinerariaefolium, and several other species in the Asteraceae family. Pyrethrins are indicated for treatment of skin parasites, such as head lice. They block sodium channel repolarization of the arthropod neurons, which leads to parasite paralysis and death. Permethrin is also used to treat head lice infestation. However, the growing resistance of head lice to pyrethrin and permethrin is becoming a serious concern [88].
