Sexual Medicine Flashcards
What spirochete causes syphilis
Treponema Pallidum
Transmission routes of syphillis
- Sexual
- Accidental infection
- Blood bourne
- Transplacental
Describe the three types of stages that occur with syphilis
- Regional lymphadenopathy - resolves in 3-8 weeks
- If untreated, virus spreads
LATENT:
1. Asymptomatic
LATE:
1. Spreads to MSK, mucosa, CV and neurosyphilis
Presentation of early syphilis (primary)
- Painless papule at inoculation site
- Spreads and ulcerates (painful chancre with clear margins, moist base and serous exudate on pressure
- Bilateral painless regional lymphadenopathy
- Oral sex =oropharyngeal ulceration
- Balanitis
Where else are chancre sites found
- Lips
- Tongue
- Tonsils
- Pharynx
- Anal margin
- Rectum
What is secondary syphilis
- Heamatogenous dissemination of infection
Clinical features of secondary syphilis
1, Macular, papular and hypo-pigmented lesions
- Lymphadenopathy
- Mucous membrane lesions (white/grey border may coalesce oral cavity, larynx, nasal mucosa, genitalia, anus and rectum)
- Alopecia (telogen effluvium)
- Periostitis, bursitis (bone pain)
- Hepatitis
- Glomurulonephirits/nephrotic syndrome
- Meningism
- Iritis/ anterior uveitis/ optic atrophy
Differentials of secondary syphilis
- Measles
- Rubella (cervical lymphadenopathy)
- Psoriasis (papular rash)
What is gummatous syphilis
- Gumata is syphilitic granulation tissue, nodules with central scarring
Where are gummatous syphilis found
- Skin
- Bones
- Mouth and throat
- Liver, testis
Clinical features of late syphilis
- Gummata
- CV: Aortic aneurysm, regurgitation
- Neurosyphilis: Meningovascular, general paralysis, rabes dorsals
Tabes Dorsalis: degenration of posterior columns and posterior root(difficulty walking etc)
Clinical features of babies with suyphilis
- Failure to thrive
- Skin lesions around mouth and body orifices
- Sparse hair and brittle, atrophic nails
- Hepatosplenomegaly
- Oesteochondritis and later periostitis
How is syphilis diagnosed
- Serum from chancres
- Cardiolipin antigen test
- Treponema pallidum PCR
- CSF test if neurosyphilis
- X-ray
- CT angio
- Ophthalmic slit lamp examination
NEUROIMAGING
What is seen on a syphilis serological test
- EIA positive, TPPA positive, VDRL positive, IgM positive
How i early syphilis treated
- Benzathine benzylpenecillin
treatment of late, latent, CV or gummatous syphilis
- Banzethine benzyl penicillin
Treatment of neurosyphilis
- Procaine benzylpenecilin
Histology of neisseria gonorrhoea
- Grame negative
2. Diplococci
Clinical features of n.gonnorheoa in males
Incubation: 2-5 days
- Urtehral discharge
- Dysuria
- Yellow/green discharge
- Erythema of the urethral meatus + oedema
- Anterior uveitis
Clinical features of n.gonnorheoa in females
- Asymptomatic
- Vaginal discharge
- Syduria without frequency
- lower abdo pain
Complications of n/gonnorhea
Male:
- Urethral stricture/fistula
- Prostatitis
- Epididymitis
Inflammation of scene’s glands in women
Pelvic inflammatory disease
Clinical features of disseminated gonococcal infection (systemic spread of infection)
- Gonococcal dermatitis
- Tenosynovitis
- Endocarditis
- Hepatitis
- Meningitis
Diagnosis of n.gonorrhoea
VUlvovaginalr, urethral smear for NAAT
Endocervical smear microscopy
Mid-stream microscopy: urethrl sample
Swab from area that seems infected basically
Blood culture
Treatment of n.gonnorheoa
- Ceftriaxone 1g IM single dose
