Q

What is Bacterial Vaginosis and what are its features?

A

Overgrowth of predominately anaerobic organisms such as Gardnerella vaginalis. This leads to a consequent fall in lactic acid-producing aerobic lactobacilli resulting in a raised vaginal pH.

Features
- Vaginal discharge: ‘fishy’, offensive
- Asymptomatic in 50%

Q

What are the criteria used for Bacterial Vaginosis?

A

Amsel’s criteria (3/4)

  • Thin, white homogenous discharge
  • Clue cells on microscopy: stippled vaginal epithelial cells
  • Vaginal pH > 4.5
  • Positive whiff test (addition of potassium hydroxide results in fishy odour)

Q

What is the management for Gonorrhoea?

A

First-line treatment is a single dose of IM ceftriaxone 1g

If sensitivities are known (and the organism is sensitive to ciprofloxacin) then a single dose of oral ciprofloxacin 500mg should be given

If ceftriaxone is refused (e.g. needle-phobic) then oral cefixime 400mg (single dose) + oral azithromycin 2g (single dose) should be used
