Herpes zoster este o boala infectioasa acuta, specifica pacientului adult, dar destul de frecventa si la copii, cauzata de virusul varicelo-zosterian. Evolutia acesteia este de 1-3 saptamani, vindecarea fiind de obicei fara sechele si imunitatea ce apare in urma acestei infectii este durabila, protejand organismul de o reinfectare.
Exista situatii in care virusul se reactiveaza (boli, traumatisme locale, stari casectizante, cura de slabire, oboseala, scaderea imunitatii), moment in care acesta se multiplica si afecteaza specific unul sau cateva traiecte nervoase. Clinic, debutul este aparent fara nici o cauza si debuteaza cu durere locala manifestata prin furnicaturi, usturime, hiperestezie pana la durere intensa cu cateva zile inainte(1-4 zile) de aparitia leziunilor.
In functie de profunzimea leziunilor, local pot ramane dupa vindecare: usoara atrofie, leziuni restante pigmentare si chiar cicatrici.
Persoanele cu herpes zoster sunt contagioase prin leziunile cutanate, putand transmite virusul persoanelor ce nu au facut varicela.
Tratamentul trebuie instituit cat mai rapid deoarece, desi evolutia este autolimitata, fara complicatii in general, riscul major este de persistenta a durerii dupa vindecarea leziunilor. Tratamentul local al leziunilor presupune topice: antivirale, cicatrizante, antipruriginoase.
Herpes zoster shingles is more commonly known as simply shingles and affects around 3 in every 1000 people in the UK each year. Herpes zoster shingles gets its name from the herpes varicella-zoster virus (VZV) which is also responsible for chickenpox which most people will suffer from as a child.
After a person has suffered from chickenpox, the body will develop the antibodies to ensure that the person is immune from the virus. It is not possible for anyone to catch shingles from another person; although it is possible (on rare occasions) that chickenpox can be caught from someone suffering from shingles. Sufferers of HIV and AIDa€™s are at a larger risk of developing shingles than the general population, with the possibility of getting the virus 25 times higher. Young healthy adults and children are least at risk of developing shingles and those that do rarely suffer from anything other than mild symptoms. Chickenpox and herpes zoster shingles are very similar in appearance and both have red spots which develop into blisters and then scab over. Herpes zoster shingles sufferers will generally suffer a feeling of pain several days in advance of the rash appearing. Should you feel any of the symptoms mentioned then it is important to seek medical attention immediately. The initial symptoms of the herpes zoster include fever, headache and malaise and may result in incorrect diagnosis.
Shingles is caused when the virus causing chickenpox awakens again in certain nerve cell of the body. If rashes appear on the skin, the diseases can be diagnosed by physical examination because only some diseases produce rashes in dermatology.
An antiviral drug stops the VZV replication in the body and reduces the herpes zoster duration with minimum side effect. Corticosteroids are commonly used in the treatment of infection even though it has unsuccessful clinical trials. In normal cases the pain and rashes drop down in 3 to 5 weeks but, in some cases the patients has to face very painful situation called postherpetic neuralgia which is difficult to treat. Varicella virus is prevalent worldwide and is highly infectious and can be transferred from one generation to other. In general, the herpes zoster is not a seasonal disease and do not have occurrence in epidemics. From the above given information we can conclude that the Herpes zoster is a non contagious disease which can be found in children as well as adults and is caused by the reactivation of VZV virus in the nervous cell leading to rashes. Infectia primara produsa de acest virus provoaca varicela (varsatul de vant) cele mai frecvente imbolnaviri producandu-se in copilarie.


La unele persoane virusul ramane cantonat la nivelul ganglionilor spinali si nervilor cranieni pentru o perioada lunga de timp, fara nici un fel de simptomatologie. Semnul distinctiv este afectarea cutanata pe dermatoame (tegumentul aferent unui nerv), unilaterala(ex. Eruptia caracteristica se produce in valuri, asemanatoare celor din varicela(varsatul de vant), la intervale de cateva zile, timp de 2-4 saptamani.
De aceea este foarte important sa fie izolate la domiciliu si sa nu intre in contact cu copii, gravide si persoane adulte neimunizate. The virus is caused by an infected nerve and the area of skin around it; the results are pain in the infected area and a rash which is irritable and itchy. The VZV virus will remain dormant in the nervous system and usually remain that way for life. No reason is known for this being the case but it is thought that a decrease in the immune system is the biggest factor. Recent organ transplant patients are also of a higher risk because of the medication needed to supress the immune system in order for the body to accept a new organ. Unlike chickenpox, shingles generally will affect only a specific area on the right or left side of the body and usually the chest and abdomen.
Pain will begin as a burning sensation or oversensitivity of the affected area and will remain constant and dull.
It is a viral disease characterizing painful skin rash with blisters in a limited area of the body.
These symptoms are followed by burning pain, itching, hyperesthesia (oversensitivity), or paresthesia.
In cases of few adults, their contact with the children affected with varicella receives immune boost.
Acyclovir is the standard drug used but these days more efficient drugs like famciclovir and valacyclovir are used. Herpes zoster can be re-activated as zoster sine herpete but, without an accompanying rash. Varicella can be fatal to the individual who are affected in the later stages of life or have very low immunity level.
Pacientii pot prezenta semne asemanatoare unei viroze respiratorii: febra, cefalee, astenie.
Zonele cele mai afectate, in ordinea frecventei sunt: torace, cap, gat si membrele superioare. Algia postzosteriana se poate manifesta de la o simpla senzatie de furnicaturi, hipersensibilitate la stimuli normali, pana la dureri atroce, care altereaza calitatea vietii bolnavului, cu tulburari de somn si care necesita tratamente puternice antialgice si sedative pe perioade lungi de timp, uneori chiar toata viata. Shingles will usually last four around 2-4 weeks during this time a sufferer will feel exhausted, run down and often depressed. However, problems that lead to a weakening of the immune system can cause the VZV virus to become reactive, resulting in shingles. Bone marrow transplant patients are also at higher risk due to the conditioning provided prior to transplant weakening the immune system.
The initial infection varicella zoster virus (VZV) causes chickenpox which occurs mostly in children and young people. Also, the lymph collected from the blister is checked for the polymerase chain reaction for VZV DNA or checked with an electron microscope for virus.
This condition affects several level of neural system and leads to several cranial neuropathies. Infection of such disease is a problem in hospital which takes care of the patients suffering from varicella. The possible risk factors of the disease include mechanical trauma, exposure to immunotoxins and genetic susceptibility.


Upon further inspection it was found that the cases do not increases in areas where the vaccine for varicella was not popular.
Pe tegumentul afectat apare roseata si eventual un usor edem, iar la scurt timp pe suprafata lui se dezvolta buchete de vezicule pline cu continut sero-citrin ce devine treptat purulent.
In cazul afectarii nervilor cranieni pot apare si alte manifestari: pareza faciala(nervul facial), vezicule la nivelul cavitatii bucale(nervul trigemen), afectarea conjunctivala si ale altor componente ale globului ocular. Tratamentul general trebuie sa includa, pe langa tratamentul antiviral(aciclovir, valciclovir, brivudina), urmat conform schemei recomandate minim 7 zile, si un tratament antialgic si antiinflamator pe o perioada mai lunga, de cateva saptamani. The name herpes zoster is derived from the German word zoster, meaning 'belt' after characteristic belt like dermatomal rash.
During pregnancies, the first infection with VZV can cause infection in the fetus and complexities in the new born, but this chronic infection is not related to fetal infections. Acestea se vor rupe, lasand in urma eroziuni ce se acopera de cruste persistente, in medie 7-10 zile. The pain is from mild to extreme in the effected dermatome, with sensation such as stinging, tingling, aching, numbing or thumbing. Shingles is not a contagious disease but a person can get affected with direct contact (skin to skin) with a blister. It is intended for general informational purposes only and does not address individual circumstances.
It is not a substitute for professional medical advice, diagnosis or treatment and should not be relied on to make decisions about your health. Never ignore professional medical advice in seeking treatment because of something you have read on the WebMD Site. Itchy blisters that appear after hiking, gardening, or spending time outdoors could be a reaction to poison ivy, oak, or sumac. The first time someone is exposed to the virus, it causes the widespread, itchy sores known as chickenpox.
If you have shingles symptoms, see your health care provider even if you think you've never had chickenpox. Many childhood cases of chickenpox are mild enough to go unnoticed, but the virus can still linger and reactivate. In most healthy people, the blisters leave no scars, and the pain and itching go away after a few weeks or months. People older than age 60 are 10 times more likely to get shingles than children under age 10.
This pain, due to damaged nerves in and beneath the skin, is known as postherpetic neuralgia. Prompt treatment can make a case of shingles shorter and milder, while cutting in half the risk of developing postherpetic neuralgia. If the pain is severe or the rash is concentrated near an eye or ear, consult your doctor right away. To speed up the drying out of the blisters, try placing a cool, damp washcloth on the rash (but not when wearing calamine lotion or other creams.) If your doctor gives you the green light, stay active while recovering from shingles.
In a large trial, this vaccine cut the risk of developing shingles in half and reduced the risk of postherpetic neuralgia by 67%. The vaccine won't treat a current outbreak of shingles, but it can prevent future attacks if you have already had shingles.
