What is syphilis?
Syphilis - classical venereal disease characterized by chronic course, lesions of the skin and mucous membranes, bones, nervous system and internal organs.In its development, syphilis goes through four periods.How does syphilis on each of them?
This is the incubation period, which lasts from the moment of infection to the appearance of the chancre (the first signs of syphilis).The first period lasts 3-4 weeks.Practice knows cases as the extension of this stage of syphilis up to 3-6 months, and shortening up to 10-14 days.Clinical manifestations are absent at this stage.
period of primary syphilis is characterized by the development of the chancre at the site of entry of the pathogen.Syphilitic ulcer (chancre) has a rounded shape, smooth bottom, clear saped edge.Painless ulcer allows it to remain undetected for a long time.The presence of pain is probably only in the event of the accession of secondary infection.Sometimes the disease is manifested in several ulcers, which are crescent, linear or oval shape.In most cases, syphilitic ulcer disappears spontaneously, without any treatment.
secondary syphilis period stands out the appearance of skin on different parts of the characteristic rash (secondary fresh syphilis).This occurs after 9-10 weeks, since infection.The rash of syphilis is a barely visible pustules, nodules or patches.About two weeks later the rash runs independently, which signals the beginning stages of secondary latent syphilis.There is a lack of symptoms.The development of secondary recurrent syphilis makes itself felt the appearance of visible changes of the skin.There is a development of white spots, the hair falls out, there are small and indistinct, grouped rashes.
period of tertiary syphilis is possible in 5-15 years or more after onset of the disease if the patient did not receive the necessary treatment.Manifestations of the Tertiary period - syphilitic tubercles (gumma).They can develop into any of the internal organs, skin and bones.Later gummas partially dissolve, exposing the destruction and bodies in which to develop.There is ulceration of the nasal mucosa, the rear side of the pharynx, hard and soft palate.The defeat of the nasal septum leads to its destruction, that ends in a failure of the nose.Next, affected brain and spinal cord, there is a progressive paralysis and dementia.
