1. A man has cauliflower-like warts and another woman has cervical intra-epithelial neoplasia. Which HPV types are respectively responsible, and what can happen in pregnancy?
- ATypes 16 and 18 for warts and 6 and 11 for neoplasia; warts always regress
- BTypes 6 and 11 for warts and 16 and 18 for neoplasia; warts may enlarge and rarely obstruct labour
- CTypes 6 and 16 for both; warts are unaffected
- DTypes 11 and 18 for both; warts shrink
Show answer
B. Types 6 and 11 for warts and 16 and 18 for neoplasia; warts may enlarge and rarely obstruct labour Benign genotypes 6 and 11 cause anogenital warts; types 16 and 18 cause intra-epithelial neoplasia and cancers; in pregnancy warts may increase dramatically.
2. A 49-year-old with two new partners has fishy discharge, three days of intermenstrual bleeding and a thin grey discharge without pain. Which approach is best?
- ANAAT for gonorrhoea, chlamydia and Trichomonas plus empirical metronidazole, because BV does not cause cervical bleeding and metronidazole covers TV and BV
- BCeftriaxone, doxycycline and metronidazole together
- CClindamycin cream alone
- DAwait results without treatment
Show answer
A. NAAT for gonorrhoea, chlamydia and Trichomonas plus empirical metronidazole, because BV does not cause cervical bleeding and metronidazole covers TV and BV BV does not cause inflammation or cervical bleeding so cervicitis from gonorrhoea and chlamydia should be tested; syndromic treatment is not preferred when testing is available.
3. A woman with gonorrhoea is asymptomatic, and a neonate has purulent conjunctivitis with lid oedema. Which statements are correct?
- AAbout 80% of women are asymptomatic, and gonococcal ophthalmia neonatorum needs urgent treatment to prevent corneal damage
- BAbout 80% have symptoms, and neonatal disease is viral
- CAsymptomatic infection is rare, and treatment is optional
- DAbout 20% are asymptomatic, and ophthalmia neonatorum is trivial
Show answer
A. About 80% of women are asymptomatic, and gonococcal ophthalmia neonatorum needs urgent treatment to prevent corneal damage About 80% of women with gonorrhoea are asymptomatic; conjunctivitis must be treated urgently to prevent corneal damage.
