- Pediculosis - still not losing ground
What is pediculosis
Pediculosis - lice is, a condition caused by lice - blood-sucking insects, parasites of humans and mammals. This louse - strictly specialized parasites that are found only in certain types of animals. Per person parasitize headache, wardrobes and pubic (ploschitsa) types of lice.
The entire life cycle of head lice runs on the host, the host is, they meet by chance and live long. Lice feed on blood, often, but small portions for a long time can not starve. The cycle consists of the development of lice-delayed female eggs (nits), which then turns into a larva (it takes three of age) and adults (mature individuals). Lots of life for the female body lice - 46 days for male - 27 days. Eggs (nits) are bonded by means of a female secret glue glands to the hair or tissue into the villae. Over a lifetime, the female lays up to three hundred eggs. Lice are transmitted from person to person by direct contact, through clothing or personal hygiene.
Biting lice cause severe itching, which leads to scratching and skin irritation. Lice (mainly wardrobes) infect human typhus, trench fever, relapsing fever. A person infected with these infections crush insects and rubbing cavity fluid lice with infectious agents in scrapes and scratches.
Signs of head lice
There are lice scalp, the skin of the body and skin pubis. Pediculosis capitis head lice cause. Primarily affecting the occipital and temporal regions, especially in the presence of long hair (mostly women and children). Head lice are glued their eggs (nits) to the hair shaft near its exit from the skin. On the ground, biting lice due to scratching develop pustular infection, while often an increase in the cervical, occipital and BTE lymph nodes. In advanced cases, copious purulent discharge stick hair, thus can form a mat - like knocking down the hair felt.
Lice cause skin torso body lice that live and lay eggs mainly in the folds of linen, from moving to the skin only for sucking blood. It affects mainly the neck and lumbar region - places where clothing fits tightly to the body the most. When the body lice on the skin there are numerous scratches, often associated infection (pyoderma). During the years of the existing lice develop skin lesions, which are called "disease vagabonds": the skin becomes rough, thick, changes (darker) the color, especially in the lower back, shoulder blades, shoulders and inner thighs.
Lice skin pubis cause pubic lice (ploschitsy), which parasitize mainly on skin pubis, lower abdomen and thighs, where they can move on to other parts of the body covered by hair (chest, legs, armpits, mustache, beard, eyelashes, eyebrows, and children - on the scalp). Ploschitsy proboscis firmly attached to the place of exit from the skin and hair to the hair. In place of their bites are peculiar round of up to one centimeter patches of blue-gray color - the so-called blue spots, which are caused by exposure to saliva of the parasite hemoglobin
Hemoglobin: worse - low or high?
the blood of the host. Scratches and pustular skin disease with pediculosis pubis is rare. Infection of pubic lice
Pubic lice - parasites who drink our blood
usually occurs by sexual contact or by linens.
For the treatment of uncomplicated head lice, apply the following ways (better after a hair cutting):
- rubbed into the scalp kerosene mixed with vegetable oil, then covered his head compress paper and tied with a handkerchief for 30 minutes, then wash the head with warm water and shampoo;
- is applied to the scalp kerosene-soap aqueous emulsion concentrate which is prepared from a kerosene-soap emulsion (comprising 50% soap and 50% kerosene), adding to 100 ml of concentrate to 1 liter of warm water; cover head compress paper and tied with a handkerchief for 30 minutes, then wash the head with warm water and shampoo;
- solution nittifora - rubbed into the scalp, and then waiting for the hair is dry and does not wash his head for two weeks, then washed head and if necessary re-treated;
- shampoo anti-bits: the hair is wetted with water and then applied to a shampoo is rubbed into the roots of his hair is rinsed, washed and rubbed again with warm water; treatment is carried out for two days.
To treat lice wardrobe essential frequent soapy bath and special treatment bed, underwear and all outerwear (disinfestation).

Itch mite - no one is immune - Scabies

- Itch mite - no one is immune
What is the itch mite
Itch mite - a type of arthropod, are parasites of man. He dwells in the human skin and feeds shelled horny scales of the surface layer of skin, causing a parasitic disease - scabies.
Itch mite is very small, so it can be seen only under a microscope: the length of the females - 0, 3-0, 4, male - to 0, 2 mm. Under the microscope you can see that the shape of the tick oval mouthparts it protrude slightly in front, side, seen four pairs of legs, two front fitted with suction cups (with their help mite moves) and spikes (they help mite to penetrate deep into the skin), and two rear - bristles (they do not give a mite to deviate from the desired direction - forward only).
In order to detect scabies mite and confirm the diagnosis of scabies, conducted laboratory studies of biological material taken with a needle under the control loops from the blind (far) end of scabies progress.
The life cycle of itch mite
Fertilization occurs on the surface of the female human skin, male then dies. The female forelegs suckers attached to the skin, jaw movement gimlet superficial layer of skin (epidermis), performing first vertical kolodtseobraznye, barely visible holes. Then it parallel to the skin surface S-shaped digging itch moves, the length of which is rarely more than 1-3 cm. The epidermis female implemented within 15-30 minutes, and is located at the far end of itch stroke, gradually moving on (per day per 1 mm) . Periodically, she stops and digs in the "roof" of the hole through which the air required for its activity.
6-8 weeks of life, the female lays up to 50 eggs, of which 3-7 days after laying larvae appear (they become sexually mature after three molts). Mature mites are raised on the surface of the skin and mate, the males die after fertilization, and the fertilized female burrows into the skin. The whole cycle takes place in about 10-14 days. During its activity the female selects a special, easily absorbed by the skin substance that contributes to the loosening of the horny layer of the epidermis.
Lessons from human skin mites, under favorable conditions, e.g., at a temperature of 15˚, live from 5 to 15 days. At zero temperature, they die within a few minutes. Proglazhivanie linen hot iron and boiling lead to rapid death of mites, larvae and eggs.
Scabies - methods of infection and symptoms
Scabies - a disease which is caused by scabies is found only in human skin. Scabies is transmitted from person to person, from an animal infected with it impossible. Infection occurs through direct contact with the skin of a sick person (in the hand, by sexual contact, and so on), through clothing, bedding and any other items, which touched the patient with scabies.
After infection takes several days to a week or even up to six months (the incubation period) and then the first signs of scabies - severe itching - the result of increased (allergic) reaction to the mites themselves and emissions of the substance. Such different period incubation period is explained by the fact that allergic reactions
Allergic reactions: how to understand why you tickle in the throat
at first contact with the allergen are not immediate, so when first infected with scabies itching appears after some time (usually a few weeks), and during the second - almost immediately.
The skin of the patient with scabies is covered with thin gray stripes (itch moves) with small bubbles (exit site of the tick on the surface), dry in the crust. The bars are gray in color because of the congestion in the itch moves dirt particles, mite eggs and excretions. All this is a great breeding ground for disease-causing bacteria, so to mange often joins a bacterial infection in a pustular rash.
Attractive just to tick a thin soft skin the inner surface of the elbow, interdigital spaces and toes, wrists, feet and genitals. And as the children tender skin on the entire body surface, it may be affected by scabies everywhere.
Treatment and prevention of scabies
For the treatment of scabies
Scabies - when overwhelmed by ticks
using drugs that destroy the itch moves and causes the death of the mites, their eggs and larvae (sulfuric ointment, benzyl benzoate, spregal both). They are used strictly in accordance with the instructions.
But the task of treatment is also to prevent re-infection, so the clothes, linen and all the items to which touch the patient is subjected to disinfection - it is also the prevention of infection with scabies others.
