 Pityriasis or multicolored lichen Colorful lichen: relapses  Colorful lichen: relapses
   - A common fungal skin infection. Fungus gives the natural pigmentation of the skin, which leads to appearance of small spots, usually dark in color. These stains may have more light than natural skin tone, color, but in any case they have clear boundaries. Most often, these spots are formed on the torso and shoulders. Disease are particularly susceptible to teenagers and people under the age of 30 years. When exposed to sunlight the symptoms of tinea versicolor may become more visible.

Antifungal ointments, lotions and shampoos can accelerate the recovery of patients pityriasis versicolor, but even after successful treatment of the skin tone may be uneven for several more weeks. People who once had been ill pityriasis versicolor, relapses occur frequently - typically they begin to warm, wet weather.

  • The reddish, dark brown, pink, or white spots on the skin White spots on skin - What are the causes and how to treat?  White spots on skin - What are the causes and how to treat?
  • Itching (usually mild to moderate);
  • Defurfuration skin (the symptom of the disease owes its name).

In most patients, stains and peeling occur on the back, chest, neck and forearms.

Seek professional medical help if a peeling and itching can not handle their own means (eg, intensively moisturizing cream), if the rash covers large areas of skin, and if developed recurrent episodes of infection.

  • Sweating;

  • Hormonal changes;
  • Weakened immune system The immune system - how it works?  The immune system - how it works?

When symptoms of tinea versicolor can contact your family doctor, but he will most likely refer you to a dermatologist. To diagnose pityriasis versicolor, a specialist is usually fairly simple examination of the patient and the information obtained from his story about the symptoms and course of the disease. If you have any doubt about the diagnosis, the doctor may take a sample of skin flakes from affected areas for further study under a microscope.

Analysis on rotavirus infection - find faults in the body

 Analysis for rotavirus infection
 Rotavirus - is one of the most common diseases in infants and young children worldwide. Most children who are not vaccinated against rotavirus, they become infected before they turn three years. There are many different strains of rotavirus, and one person can be infected by several of them. Determine their help in the analysis of rotavirus infection.

The infection is highly contagious and usually goes away on its own in just three to nine days. However, it can be very dangerous for people who take immunosuppressive drugs after a bone marrow transplant, and for older people with poor health. Most of the adults, it occurs with symptoms of mild and easily tolerated.


When doing analysis on rotavirus infection

Analysis on rotavirus infection can be administered to patients who have had symptoms of the disease as fever, nausea, Nausea - there may be problems with the nervous system  Nausea - there may be problems with the nervous system
 , Vomiting, diarrhea Diarrhea (diarrhea) - a familiar nuisance  Diarrhea (diarrhea) - a familiar nuisance
 . Diarrhea during infection with rotavirus can be a relatively weak and very strong and long lasting. However, many patients experience severe abdominal cramps, which briefly stopped immediately after defecation. Diarrhea and vomiting can lead to dehydration, which is especially dangerous for young children. If you suspect a rotavirus infection in a child as soon as possible to see a doctor and pass the necessary tests.

The amount of virus in the stool reaches its peak after three to five days after the first symptoms of infection.

Then his concentration starts to decrease, and rotavirus excreted from the body within a few days after the acute phase of the illness ends. Samples were collected in eight days or more after the onset of the disease may not contain enough virus to test for rotavirus antigen gave a positive result.


Fecal rotavirus infection

Fecal rotavirus infection does not require special preparation of the patient, but the collection of samples is not recommended after a patient took laxatives, use of rectal suppositories or enemas did.

To collect the stool can not be used toilet paper. Faeces intended for analysis must not come into contact with urine and toilet - this may affect the accuracy of test results. To analyze only one or two grams of feces. The sample must be placed in a sterile plastic container and close the lid tightly. It needs to be transported to the laboratory on the same day. If you do not go there immediately, can be stored for several hours in the feces container in the refrigerator. On the container must indicate the name of the patient and the time of collection of images for analysis; depending on the rules of the hospital or clinic, they can specify either the patient or members of the medical staff.



Modern kits for diagnosis of rotavirus infection are designed to detect rotavirus antigen VP6 of group A. At the present time there are several licensed kits for such tests, and they differ about the same accuracy. Recent studies have shown that the diagnosis carried out by means of such kits can be a pretty big chance to give false-positive results - especially in children vaccinated against rotavirus. However, the probability of false negative results is much less - provided that the analysis is done too late. For the diagnosis of rotavirus infection can also use blood tests Blood tests: a mirror of health  Blood tests: a mirror of health
   or vomit, but fecal How to pass a stool, so as not to spoil it  How to pass a stool, so as not to spoil it
   It is used most often. Test results are reported in patients, usually every other day.

There are rapid tests for the detection of rotavirus. They allow for a diagnosis in 10-15 minutes, but in the hospitals they are used less often than conventional testing.

Additionally, rotavirus infection can be diagnosed by electron microscopy - he was used to detect the virus initially. The method is very accurate, and it can be used to detect rotavirus strains, which do not "see" the test antigens. However, this method of diagnostics of roads, and most hospitals do not have the resources needed to investigate with the help of a large number of samples. Today, this method is used mainly in special laboratories, which conducted the research.
