Folliculitis

Folliculitis is a skin condition that consists of purulent inflammation of hair follicles. Boala are manifestari neplacute, iar in formele sale grave poate duce chiar la caderea parului . The disease is unpleasant events, and in its severe forms may lead to hair loss .
Foliculita apare in mod obisnuit sub forma unor basicute pline cu puroi, localizate in jurul unui sau mai multor foliculi pilosi -saculetele din care creste firul de par. Folliculitis usually occurs in the form of small blisters filled with pus, located around one or more hair follicles-pouches from which hair grows.
Majoritatea infectiilor sunt superficiale. Most infections are superficial. Desi este insotita de mancarime, foliculita este arareori dureroasa. Although it is accompanied by itching, folliculitis is rarely painful. Foliculita superficiala se vindeca de la sine in cateva zile, dar formele grave sau recurente ale bolii necesita tratament medical. Superficial folliculitis heals on its own within a few days, but severe or recurrent forms of the disease requires medical treatment.


Cea mai frecventa cauza de foliculita o reprezinta infectia cu S.aureus , care patrunde in piele prin ductul foliculului pilos. The most common cause of folliculitis is an infection with S.aureus , which penetrate the hair follicle duct.
Glanda sebacee este o anexa a foliculului pilos; ea isi varsa produsul de secretie (sebum) in canalul foliculului; blocarea ductului, va conduce la aparitia unui chist sebaceu care se poate infecta secundar. Sebaceous gland is an annex of the hair follicle, it merges their product secretion (sebum) in the follicular canal, blocking the duct leading to the appearance of a sebaceous cyst which can become secondarily infected. Chistul sebaceu trebuie diferentiat de foliculita. Sebaceous cyst must be differentiated from folliculitis. De asemenea, infectia glandelor sudoripare de la nivelul axilei poate mima infectia foliculilor pilosi. Also, infection of the armpit sweat glands can mimic infection of hair follicles. Foarte rar foliculita se poate croniciza. Very rarely can become chronic folliculitis.

Foliculita difuza apare in urma infectiei cu P.aeruginosa , patogen provenit din apele calde, insuficient clorinate. Diffuse folliculitis occurs after infection with P.aeruginosa, pathogen from the warm waters, poorly chlorinated. In mod normal, infectia se autolimiteaza, dar au fost raportate si cazuri insotite de bacteriemie si soc septic. Normally autolimiteaza infection, but cases have been reported and accompanied by bacteremia and septic shock. Inotul in ape infestate cu schistosome aviare, favorizeaza aparitia raiei inotatorilor. Swimming in water infested with Schistosoma avian mite favors the appearance of swimmers.
Schistosomele penetreaza foarte usor pielea, prin porii si ductele foliculilor pilosi, determinand aparitia unei reactii alergice insotita de prurit intens si eritem (roseata pielii). Schistosomele easily penetrates the skin through pores and hair follicles, ducts, causing an allergic reaction accompanied by intense itching and erythema (skin redness).

Furunculul reprezinta tot o infectie a aparatului pilo-sebaceu, determinata de S.aureus. Furuncles is also an infection of the pilots, sebaceus, caused by S.aureus. Evolutia acestuia este mult mai zgomotoasa, insotia de distructii tisulare dermice. Its evolution is much louder, accompanied by dermal tissue destructions. Furunculul apare doar pe suprafetele pielii acoperite de par, inflamatia fiind centrata de foliculul pilos. Furuncles appears only on the skin surface covered with hair, hair follicle inflammation is centered. Daca nu se intervine cu medicatie antibacteriana si drenaj chirurgical, infectia se poate complica prin extensie regionala. If it does not interfere with antibacterial medication and surgical drainage of the infection may be complicated by regional extension.
