Study Notes

Syphilis

Syphilis is an infection caused by the bacterium Treponema pallidum.
Transmission occurs through sexual contact with infected lesions.
Transmission during pregnancy (from mother to child) is possible.
Syphilis has three stages: primary, secondary, and tertiary.
Primary syphilis presents as a painless sore (chancre) at the site of infection.
Secondary syphilis is characterized by a rash, fever, and other symptoms.
Tertiary syphilis can cause serious complications such as cardiovascular and neurological problems.
Congenital syphilis can cause severe problems in newborns.
Acquired cases are transmitted primarily through sexual contact.
Congenital cases result from maternal infection.
Ivermectin is the primary treatment for Strongyloides stercoralis.
Standard precautions are necessary for infected individuals.
Control measures include sanitary waste disposal.

Clinical Manifestations

Congenital syphilis: stillbirth, premature birth, symptoms at birth that can include lesions, pneumonia etc.
Acquired syphilis: sores (chancres) on the genitalia or other mucous membranes (oral, anal) are common.
Secondary syphilis presents with generalized skin rashes and mucous membrane lesions.
Tertiary syphilis can affect the cardiovascular system, central nervous system (CNS), and bones.

Treatment and Prevention

Penicillin is the primary treatment for syphilis.
Alternative antibiotics (ex. doxycycline, tetracycline) are possible for individuals with penicillin allergies.
Adequate treatment is crucial to cure syphilis.
Preventing transmission through safe sexual practices is key.
Screening pregnant women for syphilis is essential.

Diagnostic Tests

Nontreponemal tests (e.g., VDRL, RPR): inexpensive, rapid, detect antibodies.
Treponemal tests (e.g., FTA-ABS, TP-PA): confirm syphilis, detect treponemal antibodies.
CSF tests: assess for neurosyphilis.
Proper diagnosis depends on both nontreponemal and treponemal tests.

Isolation of the Hospitalized Patient

Standard precautions are required.
