Description of scabies

It is a specific parasite skin damage, it is called. Dermatosis caused by arthropods. Among the so-called. Epizoonózy.

Scabies can be defined as itchy, portable, parasitic skin disease. Scabies is a relatively common dermatosis which causes less epidemic in an environment where the assumption of a larger movement of people, in combination with lower levels ofhygiene. Scabies can affect patient departments of hospitals, refugee camps, prisons, etc.

It is estimated that worldwide are affected by scabies, about 300 million people, and it is interesting that there is a cyclical increase in the number of disease every 15 years. The reason for this is unclear, however, since it can be correlated with the level of social and health conditions. In the Czech Republic in 1993 recorded 134 cases per 100 000 population, which was at our maximum. This number tends to decline: in 2005 it was only 32 cases per 100 000 population.

Originator of Scabies is a female Sarcoptes scabiei (Sarcoptes scabiei), which is a mite order Acarina, suborder Astigmata and family Sarcoptidae. Mites, which has a size of about 300-500 microns, is an obligate human parasite (obligate parasite means that it is able to infect only man).

Then the mites in the skin creates a human corridor (actually it forms the last layer of skin, which is known as the stratum corneum layer rohová-). In these corridors female defecates and lays eggs. On the human female survives about 4-6 weeks, and the average cost of 40 to 50 eggs, only one tenth but for the next 14 days developed adults.

For mites is characterized by that it is outside the human organism very sensitive to drying and moisture. At room temperature, it is unable to move, and die within three days. If the issue zakozky temperatures around 50 ° C, and die within 10 minutes.


Risk factors of psoriasis

The primary risk factor is contact with an already infected person, then there is a low level of hygiene in the family, stays in facilities with more people and so on.


Preventing Psoriasis

Signs and symptoms of scabies

If the fact that mites get into a person’s skin and cause disease, to take effect after 4-6 weeks – ie.The incubation period is a month to a month and a half. The first and most prominent manifestation of the disease is very intense itching which typically emerges at night. Itching is referred to as pruritus. This relates to the fact that man is at night under the covers, and more Zahran, which zákožce enable better stamina.

Furthermore, on the skin, for psoriasis in typical locations, outbreaks of the presence of mites.These sites are: interdigital spaces of hands, wrists, elbows, armpits, around the nipples,navel, genitals, buttocks, legs and arches.

Patognomickým flag (flag which occurs only in the disease) are tunnels, which are usuallysigmoidal shape bělošedavé color and length 5-15 mm.

Furthermore, then the secondary symptoms, which may include ekzematizace skin excoriation (skin injuries after scraping), small pimples and the like.

From the classic form of psoriasis still we distinguish several specific options which may cause diagnostic embarrassment, because they are not entirely typical in terms of symptoms and occurrence. One form occurs in people with high hygienic standard. For this it is not so obvious skin lesions, but is present persistent itching night. This variant is called scabies Scabies washed.Some assistance in diagnosis may be finding that this nocturnal itching suffer more family members.

Another type of psoriasis is called scabies nodularis, which is characterized in that its localization is similar to classical psoriasis, but there is a heightened immunological reaction, so that the formation of the large buds and nodes on the skin.

The last option is scabies norvegica (or scabies or scabies crustose hyperkeratotica), which is manifested by large buds and flaking skin. This variation is due to the large amount of parasites (in millions). Affected are people with impaired immunity (immunosuppressed individuals), as well as people who have reduced susceptibility to itching and mentally retarded. Another difference is that this type of psoriasis can affect the head, neck and nails.


treatment of Psoriasis

Treatment of psoriasis includes combating parasites, healing of skin lesions and the introduction of sanitary measures that are designed to prevent the further spread of the parasite. We used therapies sulfur and lindane.

Sulfur is used in an ointment base: adult patient use 10 to 20% sulfur petroleum, whereas in children it is used 2.5% ointment. This ointment is administered 1 × 24 hours for 3 consecutive days. Lindane is used according to the manufacturer’s instructions. In the US, using Permethrin,which is contained in some chrysanthemums, and currently coming to our market.

Therefore, the treatment was successful, it is necessary to observe the principles of topical treatment. The preparation should be evenly rubbed into the skin after a bath on the entire bodyafter a bath, however, thoroughly dry the body.

Every day you need to change underwear and bed linen to be washed at a minimum temperature of 60 ° C, iron and 3 days do not use. Other clothes or shoes do not use at least 5 days.

In some countries, the overall treatment of psoriasis, especially the use of ivermectin.
