Shingles - an acute infectious disease that affects the peripheral nerves in some areas of the skin, which leads to inflammation of the posterior roots of the spinal cord, intoxication and the emergence of bubble rash.Most often, the infection affects children between the ages of ten years and adults (mostly elderly).A distinctive feature of shingles is that it develops only in people who have had chicken pox.Upon contact with the shingles patients without a history of previous children, they began to develop typical chickenpox.On the appearance and progression of the disease, no racial, sexual and seasonal factors do not affect
causative agent of herpes zoster is varicella zoster virus (gerpevirus 3 types).Outside the period of exacerbation of the virus is localized in the intervertebral ganglia and dorsal root of the spinal cord.The disease often develops in people exposed to different exposure weakens the immune system (patients receiving long-term chemothera
Onset of the disease is always sharp: increases the overall temperaturebody, a feeling of tingling, burning, pain, and itching in the course of the affected nerve.Then, in the course of the nerve branches there is redness of the skin;by the end of the first day (sometimes second) there are groups of bubbles filled with clear content size from three to five millimeters.These groups are closely arranged bubbles tend to merge.Most often these eruptions occur along the intercostal nerve, one of the branches of the trigeminal nerve or the cutaneous nerves of the extremities.
In some cases, blisters and bubbles precede spotted nodules and congestive rash.As the bubbles themselves and their group surrounded whisk markedly edematous erythematous skin.Content bubbles themselves initially serous, over time it becomes turbid and purulent.
There are four main groups of symptoms: disorders of sensation, pain, skin manifestations and general intoxication.Sensitivity disorders often seen in the area of healed ulcers and rashes, but can also be observed at quite healthy areas of the skin.The signs of intoxication include: fever, weakness, loss of appetite, weight loss, nausea, vomiting.Pain appear a few days before the bubble bitterns.It was noted that they were significantly strengthened under the influence of any - any external stimuli (touch, heat, cold) and at night.When shingles, pain along the nerves may be replaced by unbearable to moderate.Sometimes patients report the presence of severe headaches that when changing head position strengthened.
Skin manifestations are also localized along the nerves and have a different view of their form of small red spots, or small vesicles filled with clear content with dark - red rim around the perimeter (held in a few weeks).In the case of a person running zoster, treatment of cutaneous manifestations may take longer than usual, as inflammation often affects the deeper layers of the skin, penetrating the dermis.In these cases, despite the fact that the blisters heal completely, in their place, they are deep scars.
With inadequate treatment and severe clinical course, shingles can lead to very serious complications.Possible complications of shingles:
- Emerging as a result of the defeat of the motor branch nerve paralysis
- inflammation of the bladder, lung and duodenum
- paralysis of the facial nerve with possible tilting face in the same direction
- vary in severityocular
- In the case of additional bacterial infection may develop festering in rashes
diagnosis of herpes zoster in the developed clinical picture presents no difficulties.Possible occurrence of diagnostic errors in an initial stage of the disease when there are sudden pain, fever and general toxicity.In such cases the possibility of an erroneous diagnosis of pleurisy, angina, acute appendicitis, renal colic and so on. The differential diagnosis is carried out with an acute eczema, erysipelas, herpes simplex.Generalized form of herpes zoster should be differentiated from chicken pox
For the treatment of this disease using drugs salicylic acid, analgin, anapirin, pironal.In severe shows injection of tetracycline and penicillin.In order to prevent complications pustular foci shown to lubricate pockets of 1-2% alcoholic solution containing a sulfonamide antibiotics or ointments, quite a good effect shows interferon cream.
In the case of localization of foci of shingles on the skin - is quite favorable prognosis and recovery occurs for three - six weeks, although the outbreak, the pain continues for several months.If you were involved in the process of the eye, the prognosis is not always favorable.
If intolerable pain sensations shows ultraviolet radiation, ultrasound, procaine blockade, electrophoresis with novocaine.A good effect in the treatment of herpes zoster have injections of interferon.
