Sexually Transmitted Diseases in Adolescents - UPDATE 2002 Marcia J. Nackenson, M.D. Section of Adolescent Medicine New York Medical College
STD’s: General Principles • If sexually active, inquire specifically. • STD’s go together. • Partner treatment. • Test of cure? Test of reinfection? • Condoms not 100% effective.
Adolescents: Highest Rates of STD’s • Cervical ectropion. • Less use of barrier methods. • Multiple lifetime sexual partners. • Obstacles to healthcare, perceived and real.
CervicitisSymptoms • Asymptomatic usually. • Must screen q 6-12 mos. • Spotting after intercourse. • Friability. • Mucopurulent discharge.
CervicitisNeisseria gonorrheae, Chlamydia trachomatis • PMN’s per high power field - not useful. • Gram neg. intracellular diplococci. • Gonorrhea culture - special media, hi CO2 • DNA probe - GC and Chlam • Chlamydia culture - prepubertal • Chlamydia non-culture: DFA, EIA, PCR, LCR, NAAT
CervicitisTreatment - Gonorrhea • Cefixime (Suprax) 400 mg PO x 1 ($7.50) Off the market 11/02! • ceftriaxone 125 mg IM x 1 • ciprofloxacin 500 mg PO x 1 ($4.00) • Beware quinolone resistance (QRNG) - Asia, Pacific, Hawaii
CervicitisTreatment - Chlamydia • doxycycline 100 mg PO BID x 7d. ($1.40) • azithromycin 1.0 g PO x 1 ($26.00) • erythromycin in pregnancy • Rescreen in 3-4 months
Urethritis • Usually male; in female acute urethral syndrome • Usually symptomatic - discharge, dysuria • Etiology: Gonorrhea Chlamydia Mycoplasma Ureaplasma • Screen: First void urine - + leukocyte esterase or >10 pmn’s/hpf • Diagnosis & Treatment : same as cervicitis
UrethritisScreening • Male: Urine leukocyte esterase 79% specificity 31% sensitivity Urine LCR, PCR - expensive • Complications: Epididymitis Prostatitis
Pelvic Inflammatory DiseaseDefinition • Acute salpingitis Endometritis Tubo-ovarian abscess • Sexually transmitted, ascending infection of the upper genital tract (uterus and fallopian tubes).
PID - Epidemiology • >1,000,000 cases /yr in US • 20% are adolescents; 1:8 risk for 15 yr old • Cost $4 billion/ yr • Risk factors - Previous PID
PID - Etiology • Chlamydia trachomatis • Neisseria gonorrhoeae • Anaerobes • Group B Strep • Gram neg. • Mycoplasma • Ureaplasma
PID - History • Sexual activity • Lower abdominal pain • Fever, vomiting, anorexia, dysuria, dyspareunia • Exposure to STD • Previous PID • Complete Gyn. history
PID - Physical Exam • Fever • Abdomen - tenderness, rebound, masses • Pelvic exam: Speculum - cervical specimens Bimanual - cervical motion tenderness adnexal tenderness Rectovaginal - masses in the cul-de-sac
PID - Laboratory Studies • Pregnancy test • CBC with differential • ESR, CRP • UA; UC (cath) if symptomatic • RPR • Tests for Gonorrhea and Chlamydia • Pelvic ultrasound
PID - Diagnosis • High index of suspicion • High sensitivity (few dx criteria) = low specificity = overtreatment • High specificity (many dx criteria) = low sensitivity = undertreatment
Specific PID Diagnosis • Endometrial biopsy • Laparoscopy • US or MRI : • TOA • hydro- or pyosalpinx
CDC 2002 - PID Diagnosis Begin treatment if: • Uterine/adnexal tenderness OR • Cervical motion tenderness
PID - Supporting Diagnostic Criteria • Temperature > 38.3 C • Abnormal cervical or vaginal DC • WBC’s on vaginal wet mount • Elevated ESR or CRP • Evidence of GC or Chlam from endocervix
PID Criteria for Admission • ( All Adolescents) • Cannot comply with outpt. PO or FU 72 hrs • Surgical emergency • Pregnancy • Severe illness • Failed outpt treatment • Tubo-ovarian abscess
PID - Management • Gyn consult only if diagnosis in doubt • Antibiotics: doxycycline 100 mg PO q12h plus cefotetan 2.0 g IVPB q12h or cefoxitin 2.0 g IVPB q6h • Pelvic ultrasound ASAP
PID - ComplicationsTubo-ovarian Abscesses • Suspect: Adnexal mass Poor clinical response Persistently hi WBC or ESR • Pelvic sono: Complex adnexal mass >30cc. • Add Flagyl 500 mg IVPB q12h • Gyn consult
PID - ComplicationsFitz-Hugh-Curtis Syndrome • Perihepatitis - Gonorrhea or Chlamydia • RUQ pain - pleuritic, radiating to shoulder • 50% increased LFT’s
PID - Sequelae • Infertility: 1st episode - 10% 2nd - 35% 3rd - 50-75% • Ectopic pregnancy: 6-10 times risk • Chronic pelvic pain: 18-24% R/O endometriosis Rx NSAIDs • Repeat PID: 12-33%
PID - Discharge Instructions • HIV counseling • Complete all antibiotics • No sex • Partner treatment • Contraceptive counseling • Condoms • Follow-up
Vaginitis • Abnormal vaginal discharge: Profuse Foul-smelling Pruritic Abnormal color
Physiologic Leukorrhea • Requires estradiol • Can be pre-menarcheal • Minimal to moderate amount • Clear to whitish • Not bothersome • Desquamated epithelial cells
Vaginitis - Infectious Etiologies • Trichomonas vaginalis • Bacterial vaginosis (BV) • Candida (usually albicans)
Vaginitis - Diagnosis • Saline wet mount: clue cells in BV Trichomonads • KOH prep:budding yeast and pseudohyphae + whiff test - fishy odor (BV) • pH >4.5: BV or Trichomonas
Trichomonas vaginalis • Sexually transmitted • Thin, green discharge,strawberry cervix • Culture most sensitive • May be identified on Pap or UA • Treatment: Flagyl 2.0 g PO stat or Flagyl 500 mg PO BID x 7d
Bacterial vaginosis • Gardnerella vaginalis and other anerobes • ?STD, link with PID • 50% asymptomatic, do not treat Pap • No partner treatment • Treatment: Flagyl 500 mg BID x7d or Metrogel qHS x 5
Candida • Pruritus, thick, white discharge • Do not treat Pap or culture • Underlying conditions: 1. Antibiotic treatment 2. Pregnancy 3. Diabetes mellitus 4. Immunosuppression • Vulvitis secondary to intertrigo
Candida Treatment • Imidazole group; nystatin less effective • Creams 3-7 d • Suppositories: 500 mg x 1 200 mg x 3 d 100 mg x 7 d • OTC: Monistat 200 mg x 3 d • Prescription: Terazol 80 mg x 3 d • PO: fluconazole 150 mg PO x 1
Recurrent Vulvovaginal Canididias • Overdiagnosed clinically • Treat: 7-14 days of topical Rx fluconazole 150 mg PO, repeat in 3 da. Maintenance therapy - 6 mo course: clotrimazole 500 mg vag. Q wk fluconazole 150 mg PO Q wk

Syphilis Diagnosis - NYS DOH • T. pallidum IgG ELISA for screening • RPR done only if ELISA + • Treponemal Passive Particle Agglutination Test then done as a confirmation
Primary Syphilis • Incubation period 9-90 d (mean 21d) • Chancre : Single, site of innoculation Painless, punched out, indurated Regional lymphadenopathy Heals 4-6 weeks
