title: Non-specific vaginitis or vaginitis of undetermined aetiology.
abstract: Vaginitis is a complex syndrome that is probably the most common outpatient disease seen by the gynaecologist. The specific aetiologies of vaginitis are many. One of the most common entities, however, is "non-specific vaginitis" which can be subdivided into: Gardnerella vaginitis, anaerobic vaginosis, and vaginitis of undetermined aetiology. The role of Gardnerella as a causative agent for vaginitis has been studied in depth but its specific role remains controversial. Anaerobic vaginosis can be diagnosed by noting on microscopic examination the presence of clue cells, free-floating bacteria and numerous white blood cells (WBC's). Culturing an aliquot of the vaginal discharge reveals a high number of anaerobes. In addition, this condition responds to antibiotics effective against anaerobes, e.g., metronidazole. Vaginitis of undetermined aetiology is more complex and is characterized by a purulent vaginal discharge, a pH of 4.0-4.6, numerous WBC's, and a high concentration of bacteria. The microbiology of this vaginitis includes many facultative Gram-negative rods and Gram-positive cocci. Anaerobes may be present but do not make up a large component of the endogenous microflora. This condition does not respond to the usual antibiotic therapies employed in treating bacterial vaginitis. Since this condition appears to be primarily an inflammatory reaction, it may be responsive to topical antiinflammatory agents such as benzydamine.
