Terms in this set (35)

curable stis
pubic lice, protozoa, bacteria
pubic lice
itching at site of infestation, visual recognition, topical insecticide
trichomoniasis
foul smelling vaginal discharge, vaginal itching; microscopic examination of discharge, treat with flagyl
syphilis
primary: chancre at site of infection, microscopic examination of discharge; secondary: rash, fever, blood test; no latent period; tertiary: widespread organ damage; treat with penicillin by injection
gonorrhea
thick, cloudy discharge from urethra, vagina, or anus; may be asymptomatic or cause PID; DNA test on discharge or urine; treat with oral antibiotics
chlamydia
thin discharge from urethra, vagina, or anus; local pain or irritation; often asymptomatic; DNA test on urine or swabs from penis, cervix, etc; oral azithromycin
viral stis
can diminish or remove symptoms with antibody compounds;
Immune system can attack the virus, but can never know if its really gone; cure is not the same
chlamydia
cases male and female sterility
US
highest incidence of incurable STI and climbing; can't cure with antibiotics
yeast infections
vaginal thrush, fungal infection, caused by sex, common-- itchy, soreness, burning in vagina
critters
pubic lice, scabies, trichomoniasis
scabies
parasitic mite, can be transmitted by touch or sexually, dig tunnels through skin
trichomoniasis
common, infection of vagina or male urethra, single cell protozoa love wetness so live there, Flagyl treats, 75% of people no symptoms, so don't know
bacterial infections
syphilis, gonorrhea, chlamydia
syphilis
increasing; more in west, (primary and secondary (has gotten into the body from the sore, like a rash), tertiary syphilis- latent period, then organs are failing
congenital syphilis
when syphilis is passed on to a baby, women with syphilis typically abort (baby born dead), can be mentally retarded and birth defects, treatment with penicillin
gonorrhea
increasing, looks like white pus, painful urination, symptoms passed on sexually very quickly, cervix infection in females (cystitis), males get in urethra
20-40, 80
-% of men up to -% of females don't have symptoms and pass gonorrhea along; now resistant to a number of drugs
chlamydia
most commonly diagnosed STI
chlamydia
increasing, used to not have test for it, spread through contact, caused by unusual bacterium and acts like virus-- has to get into cell to replicate, 50% no symptoms
75
-% of females with chlamydia do not know they have it
bacterial vaginosis
fish like odor, should check for an STI, composition of vagina changes, most common vaginal infection (stop douching)
urethritis
infection of urethra in males, can be caused by other organisms
viral stis
not technically curable, but immune system can take them down to curable levels
virus
very small, microscopic particle, not a cell, hijacks cell's DNA and causes it to replicate, some can protect themselves from host's immune system
genital herpes
caused herpes simplex virus 2
genital warts
caused by HPV- human papilloma viruses
genital herpes
virus, formerly herpes simplex 1 caused oral herpes, and HSV-2 causes genital herpes (less common, but can happen other way)
genital warts
unbelievably prevalent and incident
cold sore
fluid filled blister, caused by HSV- 1 usually, can get from nonsexual sources, can get from oral sex
canker sores
small, shallow ulcers that appear in the mouth and often make eating and talking uncomfortable (inside mouth, painful and not an STI)
women
herpes is more common among - than men (transmitted through semen)
16, 18
HPV - and - are most dangerous; flat lesions, asymptomatic, cervical and anal cancer; so need to be screened if multiple sexual partners (could be carrier), if at risk, test more
90, 6
-% HPV infections becomes undetectable after 2 years, clearance after first - months
seroconversion
can detect if infected with AIDs virus, then there is an asymptomatic period-- virus increasing and attacking, cd4 cells diminishing- replicate virus and die, then HIV than AIDs
