- Cytomegalovirus - what is its danger?
Manifestations of CMV
For a long time cytomegalovirus infection refers only to diseases of childhood. But in the course of clinical trials have established that damage can occur adult. The latent virus is in the urogenital tract of women who have a loss of genitals warts, it does not manifest itself by any clinical symptoms. Only during pregnancy it is activated viral infection, which is a direct cause of complications during pregnancy.
Complications of pregnancy with the activation of CMV infection include the following pathological conditions:
- Abortion, which complicates the first trimester of pregnancy, but may also occur at a later date (spontaneous miscarriage
Miscarriage - can you protect yourself from it?
, Premature birth)
- the development of toxicity in the early stages
- pathology associated with the formation of partial placenta accreta
Outwardly healthy woman, in which the virus is detected in the form of cytomegalovirus inclusions in the urogenital tract, can be a source of infection to the developing fetus and give him the virus. The latent form of carriers of the virus is the cause of complications in the period after birth with the development of inflammatory processes in the uterus and mammary gland (clinical endometritis, mastitis). The endometrium and breast occurs proliferation of the virus which causes abortion. Specific manifestations of viral lesions of the woman is not observed. In most cases, a virus detection is a diagnostic finding in the survey women revealed by accident.
Manifestations of CMV is often confused with acute respiratory disease, SARS, because he manifested fever, weakness, headache, and in the future may have more serious consequences in the form of pneumonia, arthritis, encephalitis, and so on.
Cytomegalovirus affects a lot of it causes inflammation of the liver, spleen, adrenal glands, urogenital system, as well as allergic reactions, skin rashes, itching. The disease leads to frequent causeless colds, bronchitis
Bronchitis - protection if the body has malfunctioned
Because of low body resistance. The characteristic features of this disease is excessive salivation
Increased salivation - deviation from the norm
. There may be vascular lesions of the eye. In women, the virus infects the uterus and cervix, urethra in men suffering and testicular tissue. It is worth noting that the infectiousness of the virus is not so great: infection to occur, you must contact the virus repeatedly or for a long time.
- by airborne droplets (sneezing), through saliva (kissing);
- through blood transfusions and organ transplants;
- through the placenta from an infected mother to the fetus;
- during childbirth;
- when feeding breast milk.
The most serious complication gives cytomegalovirus transmission of infection from mother to fetus or newborn has. When the disease of the fetus during pregnancy, the child has severe damage to the nervous system. Cytomegalovirus - one of the causes of miscarriage in early pregnancy. If intrauterine infection subsequently killed 20-30% of sick children. Unfortunately, a congenital form of Cytomegalovirus infection is virtually impossible to regulate.
Cytomegalovirus amenable to successful treatment, but it is important not to allow the mobilization of the virus.
During the activity of the virus should be the following:
- Pregnant women. Currently, one out of four women of childbearing age faces with the virus. Timely preventive measures can help prevent the disease from further complications for the baby.
- People with recurrent outbreaks of herpes
- People with lowered immunity. Cytomegalovirus usually sleeps in the body and does not cause a person harm. By reducing immunity, weakening the body's defense system, frequent colds, stress, the virus begins to show its activity.
- Particularly important is the control of people with the virus infection (HIV infection, persons undergoing chemotherapy). And without that suppress the immune system simply will not sustain this burden and this can lead to premature death.
Treatment of cytomegalovirus infection should be combined complex therapy, including direct struggle with the virus and increase protection of the body, strengthening the immune system
Strengthening the immune system - help the immune system
. To date, there is no tool that could fully banish cytomegalovirus from the body, the virus remains forever. The goal of treatment - to suppress its activity and bring it into a passive state. Carriers infection should follow a healthy lifestyle with proper nutrition, consume enough vitamins. When you activate the virus self unacceptable, only a doctor can appoint antiviral therapy in combination with immunomodulatory agents.
At the moment we are searching for the most effective antiviral drug that would effectively deal with the herpes family, including cytomegalovirus infection with. The fact is that a lot of drugs, to successfully cope with other viruses are completely powerless against cytomegalovirus. Doctors have high hopes for glitsirizinovuyu acid extracted from licorice root, which by all accounts should soon join the fight against this disease.
Polio - why immunization of the population?
October 4, 2009
Polio - a contagious, once a very dangerous disease, which in the second half of the XX century has been virtually eliminated in the Western Hemisphere. Although people were ill with polio since ancient times, its most powerful explosion occurred in the first half of the XX century, and continued before Jonas Salk created a vaccine that became widely available in 1955.
At the height of the polio epidemic in 1952 in the US alone, there were almost 60,000 cases of polio; 3000 cases died. However, the spread of vaccination, developed the so-called "wild" polio; By 1991, he was also defeated in the Western Hemisphere.
Signs and symptoms
Polio is a viral disease that is approximately 95% of cases does not cause any symptoms at all (this is asymptomatic polio). The 4- to 8% of cases the symptoms appear; There are three main forms of the disease:
- The most mild form, or abortive polio (most patients with this type of polio may not even suspect what they are sick because they are usually non-specific symptoms occur such as diarrhea
Diarrhea (diarrhea) - a familiar nuisance
, Fever, sore throat and general malaise).
- A more serious form associated with aseptic meningitis
Aseptic meningitis - non-bacterial origin
- Non-paralytic polio (1% -5% of cases observed neurological symptoms such as sensitivity to light and neck stiffness).
- The most severe form of the disease - associated paralytic poliomyelitis (seen in 0, 1% -2% of cases).
Patients with abortive polio and neparalitecheskim usually recover completely. However, paralytic polio, as its name implies, causes muscle paralysis and in some cases can lead to death.
When paralytic poliomyelitis virus leaves the intestinal tract and into the bloodstream and affects the nerves (for abortive and asymptomatic polio virus typically does not go out from the intestinal tract). Poliomyelitis can affect the nerves that control the muscles of the limbs and the muscles necessary for breathing, which can cause breathing difficulties and paralysis of the arms and legs.
Polio is transmitted primarily by ingestion of products containing the virus. For example, the infection can lead to lack of habit to wash their hands after using the toilet, or drinking contaminated drinking water.
Now all children make the mandatory vaccination against polio
Vaccination against polio - the only guarantee of protection against infection
and the probability of infection is minimal.
Although the acute phase of the illness usually lasts less than two weeks, nerve damage that causes polio, may affect human health throughout his life. In the past, some patients with a history of polio, could never fully restore the ability to use their limbs; sometimes limb shrinks, so that their use becomes impossible. Those who have fully recovered, there was a risk of post-polio syndrome, which can occur 30-40 years after the acute phase of poliomyelitis. When post-polio syndrome, nerve damage caused by disease, accelerates the normal aging process.
When polio was at its peak, the standard method of treatment for injuries of the respiratory muscles of patients in the room was a machine called "iron lungs". Limb Salvage of such treatment for a long time remained stationary. In those countries where there are still cases of polio in the treatment still use "iron lungs". It is now known about polio in the four countries - this is Afghanistan, India, Nigeria and Pakistan. As long as polio is defeated completely, it is necessary to continue compulsory vaccination of children against the disease.
