gonorrhea
transmitted: - contact with exudates from mucous membranes women: - cervix - urethra - bartholin glands - anus men: - urethra both: - pharynx - conjuntivae - anus
gonorrhea s/s
may cause cysts or abscesses purulent exudate - causes tissue damage -- fibrous tissue created --- scarring and narrowing of urethra, epididymis, or oviducts ---- possible sterility
chlamydia and trachomatis

may spread to oviducts and PID
- infertility, ectopic pregnancy

diseases with systemic involvement
syphillis
HSV
lymphogranuloma
syphillis
systemic infection of vascular system with 5 stages
- incubation
- primary
- secondary
- latency
- late stage
caused by: treponema pallidum, anaerobic spirochete.
syphillis and changes to vascular system
infiltration of lymphocytes and plasma cells
swelling
terminal arterioles and small arteries may become obliterated and not function
long term inflammation results in hardened, fibrous thickening of vessels and eventually tissue necrosis.
syphillis initial incubation
10-90 days
- primary stage after
syphilis primary stage
formation of chancre: painless, ulcerative lesion that arises at original portal of entry
- resoles spontaneously in 3-6 weeks
syphilis secondary stage
low fever Sore throat headache lymphadenopathy mucosal or cutaneous rash
syphilis latent stage
no s/s
early latent still contagious
variable length: could be more than 40 years
2/3 or pt remain asymptomatic if untreated
late stage
destructive phase
arterial lesions
circulatory insufficiency
risk to : CV and CNS
syphilis and mother to fetus during pregnancy
inflammatory response in fetus around 15wks
physical deformities
developmental disabilities
untreated mother: baby has active infection
