Subjective
Chief Complaint: 27-year-old woman presenting with 3 days of vaginal itching, discharge, and odor.
History of Present Illness:
- Duration: 3 days
- Vaginal discharge: Thin, gray-white, homogeneous
- Odor: Fishy smell
- Associated symptoms: Vaginal itching
- Negative symptoms: No dysuria, no dyspareunia, no abdominal pain, no fever
Sexual History:
- Sexual activity status (document number of partners, new partners, condom use)
- Last menstrual period
- Contraception method
Past Medical History:
- Previous episodes of vaginitis
- History of sexually transmitted infections
- Pregnancy history
Medications: Current medications, recent antibiotic use
Allergies: Medication allergies (particularly metronidazole, clindamycin)
Objective
Vital Signs: Within normal limits
Physical Examination:
- External genitalia: No vulvar erythema or lesions
- Speculum examination:
- Thin, gray-white, homogeneous discharge coating vaginal walls
- No cervical erythema or petechiae
- No cervical motion tenderness
Laboratory Findings:
- Vaginal pH: 5.5 (elevated; normal <4.5)
- Wet mount microscopy: Clue cells present
- Whiff test: Not documented (would be positive with fishy odor after KOH application)
- Amsel criteria met: 3 of 4 criteria present (homogeneous discharge, elevated pH >4.5, clue cells) 1, 2
Assessment
Primary Diagnosis: Bacterial vaginosis (BV)
Diagnostic Reasoning: Patient meets clinical diagnostic criteria for BV using Amsel criteria, requiring 3 of 4 findings: homogeneous white discharge coating vaginal walls, vaginal pH >4.5, clue cells on microscopy, and fishy odor 1, 2, 3. This patient has documented thin gray-white discharge, pH 5.5, and clue cells present.
Plan
Treatment
First-line therapy: Metronidazole 500 mg orally twice daily for 7 days 1, 2, 3
This oral regimen achieves 95% cure rates and is the CDC-recommended first-line treatment for symptomatic BV 1.
Alternative regimens (if patient cannot tolerate oral metronidazole):
- Metronidazole gel 0.75%, one full applicator (5g) intravaginally twice daily for 5 days 1, 2
- Clindamycin cream 2%, one full applicator (5g) intravaginally at bedtime for 7 days 1, 2
Important counseling points:
- Avoid alcohol during metronidazole treatment and for 24 hours after completion to prevent disulfiram-like reaction 1
- Complete entire course even if symptoms resolve
- Clindamycin cream is oil-based and may weaken latex condoms and diaphragms 2
Partner Management
No partner treatment required - Treatment of male sex partners has not been shown to influence response to therapy or reduce recurrence rates 1, 2. Routine partner treatment is not recommended 1.
Follow-up
No routine follow-up visit necessary if symptoms resolve 1. Instruct patient to return if:
- Symptoms persist after completing treatment
- Symptoms recur (recurrence is common with BV) 1
Additional Considerations
- Recurrent BV: If patient experiences recurrence, can retreat with same regimen or alternative regimens 1. For documented multiple recurrences, longer courses of therapy are recommended 3
- STI screening: Consider testing for other sexually transmitted infections (chlamydia, gonorrhea, HIV, syphilis) based on sexual history and risk factors 4
- Pregnancy status: Confirm not pregnant; if pregnant, treatment approach differs (clindamycin cream preferred in first trimester) 1
