STDs Flashcards
States in which minors can provide consent for STD care
All of them
Recommendations for routine annual screening for Neisseria gonorrheae
All sexually active females less than 25
Routine annual screening for Chlamydia
Sexually active females less than 25 years old
Yearly routine STD screening for MSM
Gonorrhea, chlamydia, syphilis
Co-management of chlamydia in patients being treated for gonorrhea
For all, even if NAAT for C. Trachmotis is negative
Test of cure and rescreening after treatment for gonorrhea
TOC at 14 days only if using cefixime; rescreen recommended at 3 months
Incubation periods of gonorrhea, chlamydia, syphilis
Gonorrhea: 1-14 days
Chlamydia: 7-30 days
Syphilis (primary): 21 days
Nontreponemal tests for syphilis
VDRL/RPR; Nontreponemal tests historically used for screening; antibody titers may correlate with disease activity and are used to follow response to treatment
Treponemal tests for syphilis
Treponemal tests historically used to confirm infection i. T. pallidum enzyme immunoassay ii. Fluorescent treponemal antibody absorption (FTA-ABS)
Stage with greatest risk of Jarisch-Herxheimer reaction
Primary syphilis (presumably higher organism burden)
Follow-up testing in syphilis
Quantitative tests at 6 and 12 months after treatment for primary and secondary; fourfold reduction in titer considered adequate
HSV initial infection characteristics
Incubation is 2–14 days. First-episode infection: Signs and symptoms i. Several painful pustular, vesicular, or ulcerative lesions on external genitalia; develop for 7–10 days and heal within 2–4 weeks
Efficacy of prophylaxis in genital HSV
Reduces the frequency of recurrences by 70%–80% in patients who have common recurrences (defined variably as at least four to six episodes in 1 year or at least two episodes in 6 months), though it is also effective in individuals with less common recurrences
Treatment options for genital warts
. Patient applied
i. Imiquimod 3.75% or 5% cream
ii. Podofilox 0.5% solution or gel
iii. Sinecatechins 15% ointment
Provider administered
i. Recommended treatment
(a) Cryotherapy
(b) Trichloroacetic or bichloracetic acid 80%–90%
(c) Surgical removal
Pathogens in bacterial vaginosis
Caused by anaerobic bacteria (Prevotella sp. and Mobiluncus sp.), Gardnerella vaginalis,
Ureaplasma urealyticum, M. genitalium, and several fastidious anaerobic bacteria replacing
Lactobacillus
Sexual partner treatment days cutoff
Generally 60 days (90 days for syphilis(
Recurrent UTI definitions
Reinfections a. Infections occurring more than 14 days after the original UTI b. 80% of recurrent infections c. Recurrence of infection by organism different from that in the preceding infection, but potentially of the same genus and species
Relapsing UTI definition
Within 14 days of original UTI; persistence of Sam organism
Epidiymitis cause and treatment
Epididymitis (Domain 1, Tasks 3, 4, 5) 1. Clinical syndrome consisting of pain, swelling, and inflammation of the epididymis that lasts less than 6 weeks 2. Most likely caused by gonococcal and chlamydial infections (particularly in men younger than 35) a. Ceftriaxone 250 mg intramuscularly as a single dose plus doxycycline 100 mg orally twice daily for 10 days
Conjunctivitis etiology
Viruses are the most common cause of infectious conjunctivitis (80%), particularly in the summer: Adenovirus, enterovirus, influenza 3. Bacteria are the second most common cause of infectious conjunctivitis, but they account for most cases in children and in the winter. Bacterial conjunctivitis is highly contagious. a. Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis
Classic symptoms of viral conjunctivitis
Pharyngoconjunctival fever: Abrupt onset of fever, pharyngitis, bilateral conjunctivitis, periauric-
ular lymph node enlargement
Classic symptoms of bacterial conjunctivitis
Bacterial conjunctivitis
a. Mattering and adherence of the eyelids
b. Lack of itching
c. No history of conjunctivitis
d. Purulent or mucopurulent discharge
Criteria for treatment of conjunctivitis
Children in day care or school
b. Health care workers
c. Hospitalized patients or patients living in health care facilities
d. Patients who are immunosuppressed, including those with uncontrolled diabetes or recent ocular
surgery
e. Patients who wear contact lenses
f. Patients presenting with purulent or mucopurulent discharge
Antibiotic treatment principles and duration in conjunctivitis
All antibiotics are equally effective (see Table 2), so older, non-fluoroquinolones should be considered first because of concerns regarding emerging resistance and cost, except in patients who wear contact lenses (because the risk of Pseudomonas infection is high).
Usually, symptoms begin to resolve within first 24 hours of treatment
vii. Treatment duration (a) 10 days in children 2 years and younger or if severe symptoms (b) 7 days in children 2–5 years old and if mild to moderate symptoms (c) 5–7 days in children 6 years and older and if mild to moderate symptoms (d) 3 days if using ceftriaxone
