Lice

(Pediculosis)

Lice (pediculosis), the scalp, the body, the pubic hair and the eyelashes can invade. Head lice are spread by close contact, body lice in cramped, crowded conditions, and pubic lice through sexual contact. Symptoms, findings, diagnosis and treatment depend on the location of the infestation.

Lice infested wingless, blood-sucking insects that the head (Pediculus humanus var. Capitis), body (P. humanus var. Corporis) or pubic hair (Phthirus pubis). These three types of lice differ significantly with respect to morphology and clinical disease. Head and pubic lice live directly on the host; Body lice live in clothing. All forms occur worldwide.

Head Lice Head lice usually infest girls between 5-11 years, but can basically almost every affected. In dark-skinned people they are rare. Head lice are transferred easily in close contact from person to person (z. B. in households and classrooms) and can be carried away from the hair by electrostatic discharges or wind. However, a transfer in this way (or by joint use of combs, brushes and hats) seems plausible, has not been established. There is no connection between head lice and poor hygiene or low socioeconomic status. The infestation typically affects the hair and scalp, but can also include other areas persisted. ?20 lice are usually involved in an active infection and there is a strong itching. The testing result is usually normal, except for occasional Kopfhautexkoriationen and adenopathy of the posterior cervical lymph nodes. The diagnosis is made by demonstrating live lice. Lice be detected by the wet hair care of the scalp with a fine-toothed comb (comb bristles are about 0.2 mm apart) is combed. Mostly, the lice found at the back of the head or behind the ears. Nits are seen more frequently and are oval, gray white eggs, which are fixed to the base of the hair shafts. Each adult female louse lays 3-5 eggs daily, so normally far more nits are present as lice, which therefore also can not be used as a measure for the Infestationsschwere.
