Back 4

b. increase penicillin resistant in Australia, insufficient for pharyngeal and anorectal infection even if "sensitive".
- Ceftiaxone 250mg IM stat + oral doxycycline for 7 days or azithormicin 1g single dose
- IV Ceftiaxone or cefotaxime for disseminated disease

c. Treponemal antibody tests are use to support the diagnosis if patient had a positive VDRL test
d. Treponemal antibody tests remain positive in 75% for life unless treatment start early
e. RPR (rapid plasma regain) is used to determine if true positive VDRL

Back 8

e. RPR and VDRL are screening test for Sypjilis, both need Treponemal antibody tests e.g. IgG to confirm diagnosis.

Front 9

Which is not true for HSV infecton? (Dunn757-8)

e) Fetal renal damage is associated with IV aciclovir use

Back 9

c) no control studies of the use of aciclovir during pregnancy doesn't prevent recurrence of genitl herpes, IV aciclovir potential cause fetal renal damage.
