Pediculosis or lice.What it is?Translated into Russian is a disease called "lice" or an infestation of lice.Contrary to public opinion that lice - a lot of war and persons of no fixed abode, get yourself on the head of a small and harmful pet can absolutely everyone.Trouble for the man are three main types of lice: head louse, Louse wardrobes and pubic louse.

reasons lice lice


head louse settled in the scalp, preferring occipital and temporal regions.This translucent insect refers to small obligate (continuously occurring) parasites and detachment puhoedovyh.Their main food - human blood.The female louse lives just over a month and lays 10 eggs (nits) a day, attaching them to the base of the hair strong adhesive secret and placing them in the form of spikelets 4-5 pieces.Their mouthparts adapted to prokusyvaniyu skin and blood sucking.When the bite of the parasite into the wound releases irritant, causing severe itching.Bitten lice person experiences an unbearable desire to comb bite, hol

ding up his hands in the wound secondary infection.It appears local inflammatory reaction, redness, crust and seal the skin at the site scratching.This infection can spread to neighboring lymph nodes.

cootie , except the itching brings more trouble, as the carrier of dangerous diseases such as typhus, Volyn fever and relapsing fever.Unlike the head, she lives in the folds of clothing, and there lay eggs.Therefore, the bites are located in places of contact with the body of clothing: a belt, in the elbow and knee bends, in the collar.

pubic louse (plaschenitsa) causes pubic lice (pediculosis pubis).This little parasite dark brown color lives in the pubic and anal area, bringing a lot of trouble with their bites.Dispatched pubic vosch mainly through sexual contact.If hair growth on the body is well expressed, that pediculosis pubis may be affected and other areas of the body.

Unfortunately, the incidence of head lice is growing every year.One of the reasons for this, in addition to mitigation, is a lack of awareness of people about the disease.Improper treatment of lice leads not only to re-infection of the patient and his loved ones, but also helps the parasites to adapt to new medicines.

As lice are transmitted

Lice can not fly and jump, but a well-crawling, running and even floats!New owner is found, guided by the smell.It is easy to get the intruder on the head, using any object that touches first the patient's head, and then the sound: a comb, hat, headphones.

at risk for infection with head lice are children, most often between the ages of 5 to 12 years.This can be explained by the fact that at this age babies are usually actively communicate closely with peers in children's groups.Children become more independent, reduced control of parents over issues of personal hygiene.But their own habits in children has not yet been sufficiently developed.Therefore, specific contact objects through which the lice infection in children can be called soft toys, costumes, bedding in summer camps and kindergartens.

Adults easily infected with lice from the children in the family, it is also possible infection of the baths, pools and bars, as well as serving child care or being in crowded teams (military places of detention).

Symptoms and Diagnosis Diagnosis

lice lice do not cause technical complications: it is enough to find live lice or nits individuals when viewed with the naked eye or under magnification.

The larger is the complexity of the psychological side of the question.The patient, when they heard that he had lice, often perceives this news with hostility.Previously, Dr. virtually impossible to prove the necessity of the treatment, as the small size of the parasite and its active movement, and often imperfect vision doctor easily raise doubts.In recent years, the situation radically changes videodermatoskopiya (examination of the skin under magnification, with a record on a video medium).Now we can confirm the diagnosis in doubtful cases.

Treating lice

How to get rid of lice?A set of drugs for the treatment of head lice today is radically different from what it was previously.Already lice treatment does not require shaving of the head (except for cases of allergy to all existing medication, it is extremely rare).Also, do not use very nearomatnye folk methods such as Kerosene oil, dust, hellebore water.In addition, they do not guarantee a positive result, but damaged hair, horrible smell, or even poisoning - is much more likely.

The pharmacy chains now present mass delousing agents (insect extermination).They all have different active substance and form (from ointments to spray).Read the instructions carefully, spend lice treatment affected areas, paying attention to the fact that:

  • Do not neglect to re-treatment - during the first treatment of the drug can "spare" some nits, which become a source of re-infection.
  • required inspection and treatment of lice is carried out simultaneously to all members of the team (the group in kindergarten, family offices), as untreated people will once again be a source of infection.For drugs that manufacturers create packaging means of which not enough at once.
  • Exactly follow all instructions - parasites adapt very quickly, and it is necessary to use more sophisticated tools.Today, preference is given to the combined drugs.
  • Within two days from the start of treatment to be washed at high temperatures and hot iron ironed all bed linen and underwear of the patient.
  • After treatment for two weeks, you need to monitor the patient's skin veils, to ensure complete freedom from lice.This time interval is due to the timing of the nits.
  • To remove nits firmly attached to the hair, you need to comb their special very fine-toothed comb.Sometimes protivopedikuleznyh means manufacturers are investing in their packaging with the drug.But they can be purchased separately.I met even special combs, which were deposited by laser incision, for a more effective result.

Complications lice

The most common pediculosis capitis particular risk to humans is not, except for the unpleasant itching and secondary infections of the scalp.Cootie - carrier of typhoid infections - today is not as common.Infection with her common mostly among people who are unable to bathe regularly and wear clean clothes.Manifested fever common fever, rash and other symptoms.In this case, the need to consult a doctor - infectious diseases and isolated treatment in the infectious department.

Pediculosis - a nasty disease, it is subject to each.Do not be ashamed of this, go to treatment and forget about this problem.
