    Study Notes

    Bacterial Vaginosis

    • Most common sexually transmitted infection (STI)
    • Diagnosed with a gram stain (gold standard)
    • Clinical criteria: thin white discharge, clue cells, pH >4.5, fishy odor with the "whiff test"

    Chlamydia

    • Most common STI (highest permissible or potentially allowed in 49 states)
    • Test of cure is not typically required unless there are other co-morbidities (like pregnancy, HIV)
    • Try to treat patient and partner together
    • No sexual intercourse for 7 days

    HSV (Herpes Simplex Virus)

    • Lifelong viral infection
    • HSV-1 (oral herpes) and HSV-2 (genital herpes)
    • Many people are asymptomatic but still shed virus
    • Testing: PCR assays for HSV DNA and IGG testing (often part of an STI panel)

    Syphilis

    • Systemic disease caused by Treponema pallidum
    • Divided into four stages: primary (ulcers or chancre at infection site), secondary (skin rashes and swollen lymph nodes), tertiary (advanced disease), early latent (first year), late latent or unknown duration (after the first year)
    • Diagnosis: Trep-pal test and RPR (reported in titer with a fourfold change, e.g., 1:4 to 1:16 indicating infection)

    Trichomoniasis

    • Usually has minimal or no symptoms
    • Consider in any woman with discharge, high-risk behaviors
    • Wet mount diagnosis has low sensitivity
    • Gold standard diagnosis: Affirm (tests for BV, yeast, and trich)

    Genital Warts

    • Caused by HPV types 6 or 11
    • Noncancerous
    • Usually diagnosed visually
    • Usually resolves within a year

    Pelvic Inflammatory Disease (PID)

    • Infection of the upper female genital tract
    • Most common cause: Chlamydia and Gonorrhea
    • Increases risk of HIV
    • Difficult to diagnose, presumptive treatment often required: CMT, uterine tenderness, adnexal tenderness

    HPV Vaccine

    • Available to help prevent HPV infections

    HIV

    • Screen everyone ages 13-64
    • Part of the STI panel
    • Rapid testing is most common; positive results are confirmed

    Bacterial Vaginosis

    • Most common cause: Gardnerella vaginalis
    • Vaginal fluid pH >4.5
    • Characterized by smelly discharge
    • Diagnosis: gram stain (gold standard)
    • Clinical criteria (need at least 3):
      • Thin white discharge
      • Clue cells
      • pH >4.5
      • Fishy odor with the "whiff test"

    Chlamydia

    • Most common STI
    • Permissible or potentially allowed in 49 states (prohibited in South Carolina)
    • Test of cure is not required unless other co-morbidities exist (like pregnancy, HIV)
    • Treat patient/partner together if possible
    • No sexual intercourse for 7 days

    HSV

    • Life-long viral infection
    • HSV-1 & HSV-2:
      • HSV-2 = genital herpes
      • HSV-1 = oral herpes
    • Many people have no signs or symptoms while shedding the virus
    • Testing:
      • PCR assays for HSV DNA
      • IGG testing (often as part of an STI panel)

    Syphilis

    • Systemic disease caused by Treponema pallidum
    • Stages:
      • Primary: ulcers or chancre at infection site
      • Secondary: skin rashes; swollen lymph nodes
      • Tertiary: advanced disease
      • Early latent: first year
      • Late latent or unknown duration: after first year
    • Diagnosis:
      • Trep-pal test and RPR
        • RPR reported in titer
        • Fourfold change (1:4 to 1:16) indicates infection

    Trichomoniasis

    • Usually no or very mild symptoms
    • Consider in any woman with discharge, high-risk behaviors, or if not included in standard screening
    • Diagnosis:
      • Wet mount (low sensitivity)
      • Gold standard - Affirm (checks for BV, yeast, trich)

    Genital Warts

    • Caused by HPV (type 6 or 11)
    • Noncancerous
    • Diagnosis: usually visual
    • Treatment: usually resolves in a year

    PID (Pelvic Inflammatory Disease)

    • Infection of the upper female genital tract
    • Most common cause - Chlamydia and Gonorrhea
    • Increased risk of HIV
    • Difficult to diagnose
    • Presumptively treat for PID:
      • Cervical motion tenderness
      • Uterine tenderness
      • Adnexal tenderness

    HIV

    • Screen all ages 13-64
    • Part of STI panel
    • Rapid test most common; positive results need confirmation
    • Referral for further management
