Dangerous Parasite

Even today, the abundance of different kinds of soaps, shampoos and gels, body wash still found lice. And uncommon. Pubic lice are quite common not only among the homeless and drug addicts, but also among ordinary people, who are often not even aware of their existence. Head lice - a blood-sucking insects - parasites of mammals and humans. This is strictly a specialized lice parasites that are found only in certain types of animals. There lice, that live only on horses, swine, dogs, and so forth. Per person lives a special kind of lice - pedikulidy, which are divided into three types: headache, wardrobes and pubic lice.

Outside the host lice are rare and short-lived. Lice feed on human blood, small, frequent meals, fasting can not be long. If louse fed 1-2 times a day, the female can drink at one time and 1 ml of blood with a body length of not more than 3 mm. Males are smaller than females drink blood and therefore less. When the bite of blood in a blood vessel is minimized, but the salivary glands produce a natural substance ploschitsy thinning and digested blood. As a result, the site of the bite appear bluish-gray spots.

A month after fertilization, each female lays about 8 eggs (nits), which are secret special glands attached to hair. After 15 days from the date of the deposition of the eggs hatch new lice. In total, during the life of the female lays up to 300 eggs, which are oblong-oval, white-yellow color and glued using adhesive secretion glands to pubic hair. Hatched larvae in half an hour start to suck the blood of the host. Caught cold, ploschitsa may fall into "hibernation" and stored in this way for months.

How is lice (pediculosis), skin pubis

The spread lice observed under unfavorable hygienic conditions, especially during the wars and other disasters. Pediculosis pubis skin called pediculosis pubis.

They can also move to other parts of the body covered with hair, for example, on the chest, legs, armpits, mustache, beard, eyelashes and eyebrows, and the children, and on the scalp.

Infection of pubic lice usually occurs during sexual intercourse, as well as in the common areas (baths, pools, etc.) And at home through the linen. When everyday way infestation often settle in atypical locations (for example, in the armpits). Ploschitsy firmly attached to the mouth of the hair follicles and hair.

Diagnosing pediculosis pubis skin

Pubic lice is very characteristic symptoms, so diagnosis can be clear already in the process of inspection. Female ploschits can be seen by the eye or with a magnifying glass. They are easier to see after they drunk the blood, which gives them a kind of brown. Detected and pubic lice nits that are attached to the hair a special adhesive composition. Externally, the nits on the hair look like dandruff Dandruff: where it comes from, and what to do  Dandruff: where it comes from, and what to do

Treatment of pediculosis pubis skin

Before treatment, the skin pubes shave and wash the skin with soap and hot water - it eliminates most of the ploschits. For the final destruction of lice and nits pubis rubbed into the skin, special ointments and solutions (such as vinegar or sublimate sulfuric ointment). From modern solution used nittifora spray- and Pax. Last used once - they wetted skin pubis, after half an hour wash it with hot soapy water.

 warts in women causes

Causes of viral infection

Warts in women - causes of this disease are not yet fully understood. However, it is known that the two main reasons - the introduction of human papillomavirus (HPV), and decreased immunity. If one of these factors is missing, the warts appear. What kind of a virus - HPV, which is infiltrating into the body, it remains there forever, causing disease only when lowered immunity?

Features of human papillomavirus

About genital warts or genital warts was known to Hippocrates. But on the human papilloma virus (HPV), humanity has learned relatively recently, in the 60s of the last century. Today, found that HPV - is one of the most common viruses, they are the majority of the adult population is infected. The prevalence of infections caused by them is increasing, as is evident, due to the deterioration of the environment, the frequent use of antibiotics, high neuro-mental stress and other factors that lead to decreased immunity.

Until a few decades ago it was thought that the main cause of cervical cancer is a herpes virus. Only at the end of the last century, it was found that the real "culprit" of cervical cancer is HPV. It was also found that there are many subtypes of HPV, some of which have low carcinogenic potential (ability to cause malignant tumors), and other high.

By subspecies (strain) with a low HPV carcinogenic potential are 6, 11, 42, 43 and 44. These subtypes cause exogenous growth (surface epithelium) warts. These are called genital warts - they rarely transformed into cancer (maligniziruyutsya).

Subspecies 16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 68 cause the endogenous (oral tissue) growth of warts. These are called flat warts - they often cause changes in the basal layer of the epithelium. Such changes are called dysplasia - they can transform into cancer. And as flat warts often located on the cervix, it is believed that HPV is a cause of cervical cancer.

As transmitted warts in women - causes infection

The most common mode of transmission of HPV - sexual, but also the way home is not ruled out in close contact with the patient and using his laundry (eg towels). A feature of papilloma virus infection (PVI) is that it is practically impossible to determine exactly when a person infected with HPV, and from whom, as the virus after the introduction of "hiding" in the cells of the deeper layers of the skin or mucous membranes and causes disease only at lower immunity.

PVI treated only if there is any of its manifestations, as to remove the virus from the human body have not yet learned.

How are warts in women

HPV can long exist in the human body, does not prove itself. The appearance on the mucous membranes of the genital warts is usually associated with a decrease in immunity. Immunosuppression may develop a cold, any acute illness, exacerbation of chronic diseases, after surgeries, injuries, stress, hormonal changes in the background (including during pregnancy), and so on.

By reducing HPV immunity "come alive" and begins to move with the cell in which it is located, towards the outer layers of the epithelium. Once on the mucosal surface, it begins to multiply rapidly and "colonize" epithelial cells, making them hard to share - this process is very fast - primary warts can grow for several hours. Then the process may either stop or continue - warts grow, capture new areas of the skin or mucous membrane, fuse together, forming a "cockscomb" or conglomerates like cauliflower.

In addition to flat warts tend to malignancy giant genital warts, in the form of huge conglomerates (Buschke-Lowenstein tumor).

How is the diagnosis of genital warts

Genital warts have a very distinctive look, so the doctor can make a diagnosis based on the examination. It is difficult to make a diagnosis only when warts are just starting to grow and have the form of small nodules. In any case, to confirm the diagnosis carried out a study taken from the surface of the warts smear - polymerase chain reaction (PCR) revealed the DNA of the virus.

In addition, a study is mandatory for syphilis Syphilis - punishment of Venus  Syphilis - punishment of Venus
