Evaluation of vaginal complaints

Area of Science:

• Gynecology
• Infectious Diseases
• Diagnostic Medicine

Background:

• Vaginal symptoms are a frequent reason for gynecological consultations.
• Traditional diagnostic methods include physical examination, pH, wet mount, and whiff test.
• Distinguishing between vaginal candidiasis, bacterial vaginosis, and trichomoniasis can be difficult using these methods alone.

Purpose of the Study:

• To evaluate the diagnostic accuracy of clinical examination for common vaginal infections.
• To determine the positive and negative likelihood ratios (LRs) for symptoms and signs associated with vaginal candidiasis, bacterial vaginosis, and trichomoniasis.

Main Methods:

• A structured literature review of published articles from 1966 to 2003 was conducted.
• Studies included symptomatic premenopausal women in primary care settings.
• Sensitivity and specificity data for symptoms, signs, and office laboratory tests were extracted and analyzed.

Main Results:

• Individual symptoms and physical examination signs have limited diagnostic power for differentiating between vaginal infections.
• Lack of itching decreases the likelihood of candidiasis, while lack of odor reduces the likelihood of bacterial vaginosis.
• Microscopy of vaginal discharge is identified as the most useful diagnostic tool for these conditions.

Conclusions:

• While typical microscopy findings can aid diagnosis, the poor performance of individual clinical factors often complicates identifying the cause of vaginal symptoms.
• Office laboratory tests, particularly microscopy, are crucial for accurate diagnosis.
• Further research may be needed to improve the diagnostic utility of clinical examination components.
