What are the characteristics of syphilis

summary

I have a cousin who is not very sensible and doesn't study when she is young. Now she often goes to nightclubs with some friends in the society, which leads to syphilis. In order to prevent this situation, I'd like to introduce the characteristics of syphilis.

What are the characteristics of syphilis

Symptom 1: the symptoms of syphilis at each stage are different. At the initial stage of syphilis, the symptoms are not obvious, but the patients feel very uncomfortable. The symptoms of primary syphilis are hard chancre. That is to say, erythema, infiltration, nodule and quick damage occur in vulva, forming painless and itchless ulcer. The base and periphery are relatively hard, accompanied by swelling of inguinal lymph nodes. Most of the patients occurred in glans and coronal sulcus.

Symptom 2: secondary syphilis is characterized by pleomorphic rash, which is often symmetrically distributed on the skin of the trunk and the flexed side of the extremities. Red or purplish red macular rash is smooth or with scales. It is not itchy or painful. The lymph nodes of the whole body are often slightly enlarged, but there is no tenderness. Some patients have flat wet eczema with moist surface around the external genitalia or anus.

Symptom 3: skin and mucous membrane damage in patients with stage III syphilis, typical lesions are nodular syphilid and gumma. The nervous system, heart blood system, liver, spleen and bone can all have pathological changes, which seriously affect the function of various organs, resulting in disability and even loss of life.

matters needing attention

It is a non-specific Syphilis Serological Test, which is often used for early diagnosis of syphilis, but it is not sensitive to latent syphilis and neurosyphilis. TPHA has high sensitivity and specificity in detecting specific Treponema pallidum antibody in serum. Once the test is positive, no matter whether the disease is active or not, it usually remains positive for life. The change of its titer has nothing to do with whether the syphilis is active or not. Therefore, it can not be used as an index to evaluate the curative effect or determine the recurrence and reinfection, but can only be used as a confirmation test of syphilis.
