GUM Flashcards
causes of genital ulceration?
- infectious (viral: HCV, varicella, CMV. bcaterial: syphilis, staph/strep, LGV, chancroid, donovanosis. fungal)
- inflammatory/immune (crohns, blistering skin conditions, aphthous)
- durg-related (FDE, topical reaction, IVDU)
- traumatic
- malignant
What tests are done for herpes?
- take a swab (send for PCR) on a wet blister/ulcer not crusted over
also offer full STI screen, syphilis serology, HIV antibody test
management of herpes?
- course of oral antiviral (e.g. aciclovir) 400mg TDS for 5 days
- 5% lidocaine ointment
- rest and analgesia
- salt watering bathing
- vaseline
- avoid sexual contact while symptomatic
- advise to disclose to partner
complications of herpes?

- recurrences
are herpes ulcers painless or painful?
painful !
differential diagnose for genital ulcers?
- syphilis
- herpes simples
- lymphogranuloma venereum
- aphthous ulceration
- trauma
- Mpox
how do you diagnose syphilis?
from lesions:
- dark ground microscopy
- treponemal PCR
in blood:
- treponemal enzyme immunoassay (EIA)
- treponema pallidum particule agglutination assay (TPPA)
- rapid plasma reagin test (RPR)
- always perform full STI screen including HIV testing
first line treatment for syphilis?
early: benzathine pencillin IM one dose
late: benzathine penicillin IM 3 doses
what tests would you do on a symptomatic female?
- high vaginal loop swab fro microscopy and pH testing - TV, BV, candida
- vulvovaginal swab ‘dual NAAT’ - chlamydia and gonorrhea. may need throat and rectal
- bloods: HIV.syph +/- Hep B/C
+/-:
- high vaginal charcoal swab
- gonorrhea cultures
- HSV PCR
- urinalysis
- preg test
what tests would you do on a symptomatic male?
- urethral smear - GC/NSU, GC culture
- first pass urine - GC/CT dual NAATs test
- bloods HIV/syphilis +/- hep B/C
MSM may need rectal and pharyngeal swabs and culutres
other swabs - MC&S/candida/herpes
other test - urine dip

MSM may need rectal and pharyngeal swabs and culutres
other swabs - MC&S/candida/herpes
other test - urine dip
risk factors for candiasis?
- immunosupression (hiv, steroids, chemo)
- high oestrogen levels (preg, luteal phase, somes COCPs)
- recent ABx
- diabetes
- mucosal breakdown (sexual contact, dermatitis)
- recurrent candidiasis
how to treat candidal infection?
fluconazole 150mg stat or
clotrimazole 500mg pessary PV stat or
clotrimazole 1% cream for 2 wks
what are some important questions to ask regarding vaginal discharge?
colour
consistency
odour
associated symptoms: pain, bleeding, itchy, rash, triggers
what examinatons do you want to do on female patient?
- external + vulval examination
- speculum examination
- bimanual examination (if abdo pain/deep dyspareunia )
what swabs are used for different organisms?
- high vaginal swab - trichomonas vaginalis/candida/bacterial vaginosis
- vulvovaginal swab - N. gonorrhoeae and C.trachomatis
what are the clinical features of vaginal candida?
- thick, white discharge (cottage cheese like)
- itching
- soreness
- vulval erythema +/- fissures, pH 4
what investigations need to be done when suspecting candida?
- swabs taken from high vaginal walls
(- culture may grow candida but doesn’t distinguish colonisation)
risk factors for candida infection
- immunouspression
- high oestrogen levels
- recent ABx (up to 3 months before)
- diabetes mellitus
- mucosal breakdown (sexual contact, mucosal breakdown)
Tx for candida?
- fluconazole 150mg PO STAT or clotrimazole 500mg pessary PV stat
PLUS clotrimazole 1% cream top BD for 2 wks
what is the treatment fro recurrent candidiasis?
recurrent = > 4 times a yr
induction followed by maintenance:
- fluconazole 150mg every 72 hrs for 3 doses
- then fluconazole 150mg x1 a week for 6 months
- clotrimazole pessaries can be used if flucon. contraind.
(+ advice on douching, remove oestrogen e.g. POP)
what is bacterial vaginosis + how is it caused?
- imbalance of vaginal flora
loss of lactobacilli that maintain pH of vagina
= overgrowth of normal, commensal, anaerobic and facultative bacteria
rise in vaginal pH
NOT AN STI
triggers for bacterial vaginosis?
- sex
- menses
- receptive oral SI
- vaginal douching
- perfumed bath product
s- change in sexual partners - presence of STI
