Impetigo: Symptoms, Causes, Diagnosis and Treatment
Impetigo or contagious impetigo is an infectious disease of the skin, characterized by the appearance on it of numerous eruptions in the form of blooms, which are bubbles that appear on the inflamed skin.The causative agent is streptococcus, the disease refers to infectious infections.
In people, the contagious impetigo is known as the "flint", due to its ability to spread quickly in children's groups, like fire.Contents: Reasons for impetigo Symptoms of impetigo Diagnosis of impetigo Treatment of impetigo Complications Impetigo prophylaxis
Reasons for impetigo
The main cause of this disease is streptococcus, it is very rare that staphylococcus can be the causative agent.People are infected by contact with a carrier of streptococcus or through common objects, in kindergartens through toys.
Not every person whose skin has streptococcus will have an impetigo.
The probability of getting sick is higher if the following conditions exist:
- Microtrauma skin;
- combing the skin with various dermatoses: eczema, contact dermatitis, allergic dermatitis, etc.;
- increased sweating;
- maceration( softening) of the skin after bath procedures;
- Rhinitis can cause impetigo on the face.
Skin contamination, changes in its acidity due to abuse of various cosmetic preparations, reduction of the general resistance of the organism against the background of chronic diseases are all predisposing factors for the onset of symptoms of impetigo.
Symptoms of impetigo
The clinical picture of impetigo is caused by the penetration of staphylococcus into the hair follicles, where it actively multiplies.As a result, pustules( blisters) filled with pus are formed.Then the bubbles are opened, the contents get on the skin and dries up in the form of crusts.
Symptoms of the initial stage of impetigo are a few red spots that turn into bubbles located on the inflamed skin in 3-4 hours.The contents of the bubbles( pustules or fliken) are initially transparent, but after a couple of hours it becomes cloudy.When the conflict is revealed, small erosions are formed, covered with a purulent discharge.Eruptions can merge due to peripheral growth.
Under the crust, a gradual healing of erosion occurs, after about a week the crusts fall off, and on the site of the rashes there are pink-lilac spots that completely disappear after a few weeks.
A typical site for the localization of rashes for contact impetigo is the extensor surfaces of the hands, trunk and face.
Diagnosis of impetigo
Diagnosis can be suspected already at the initial examination.The doctor specifies the nature of the primary rash, the features of the course of the disease.From additional methods of research use dermatoscopy.Completely confirm the diagnosis helps bacteriological study - planting of the released into nutrient media.
In the case of recurrent impetigo, the patient is recommended to study the immune status, which helps to identify abnormalities in the immune system.
Other skin diseases occur similarly: Dühring's dermatitis, neonatal pemphigus, simple contact dermatitis.A dermatologist can help distinguish these diseases from each other.
Treatment of impetigo
To ac and most pustular skin diseases, impetigo is treated primarily by prescribing local antibacterial agents in the form of ointments and creams.A good result shows solutions of aniline dyes, which have a disinfectant effect.Fucarcin or zelenka is treated with single elements, and an ointment with an antibiotic is applied to the fused elements.On the crusts formed on the site of the fliken, apply bandages with softening ointments: naphthalan or white mercury.
Treatment with systemic antibiotics in the form of tablets or injections is indicated only in severe impetigo, as well as with frequent relapses of the disease.In this case, the therapeutic regimen includes the intake of vitamin complexes and immunomodulators, which increase the overall resistance of the organism.
Folk remedies in impetigo treatment do not have the required efficacy, and abuse of them can lead to serious complications.It is better to apply them as an addition to the basic treatment.Broths of chamomile, St. John's wort and other medicines can act as a natural immunostimulant.
During treatment, do not wash plain water with a rash area and undamaged skin - this contributes to the spread of impetigo.As hygienic measures, you should wipe the skin with a solution of camphor or salicylic alcohol.
A complete cure occurs within 7-10 days of therapy.Disappear all the fiction, and in their place are temporary depigmentation sites.
Streptococcal infection is dangerous because it can spread to other organs - in the absence of treatment, development of such formidable complications as nephritis or myocarditis is possible.In weakened people, impetigo can cause furuncles, abscesses or phlegmon.
A long-term process often leads to the formation of scars and scars on the spot.
Prevention of impetigo
Measures to prevent the appearance of symptoms of impetigo are carefully observing the rules of personal hygiene.When detecting cases in a pre-school or school, it is necessary to isolate the sick person.All the items with which it is in contact are recommended to be disinfected.
