STDs/STIs (Midterm 2)
gummas can be found where
anywhere throughout the body
chlamydia symptoms? common cause? if untreated in males? if untreated in females?
chlamydia symptoms? usually fewer symptoms, or asymptomatic common cause? urethritis (inflammation of urethra) males? epididymitis females? PID
pathogenesis for herpes
following infection, virus replicates epithelial cell lysis formation of vesicles vesicles rupture, ulcerations take 2-4 weeks to heal virions remain dormant in ganglia, can reactivate
neisseria gonorrhea is what type of PID?
gonococcal
what is the most common cause of genital ulverations?
herpes simplex
HPV incubation period? symptoms? common lesion?
incubation period? 1-9 months symptoms? usually asymptomatic common lesion? condylmata acuminata (genital warts)
pelvic inflammatory disease (PID)
inflammation of organs in the pelvic cavity; usually includes the fallopian tubes, ovaries, and endometrium; most often caused by bacteria
are STDs typically transmitted from men to women or women to men?
man to women women have more complications due to delayed diagnosis
chlamydia trachomatis is what type of PID?
nongonococcal
there are 3 stages of syphilis, what are they?
primary (infectious)- chancre appears 1 month after infection, occurs at site of infection secondary (infectious)- infection spreads throughout body, skin lesions- red brown macules (flat) and papules (raised), mucous membranes- condylomata or mucous patches tertiary (noninfectious)- cardiac and central nervous system involvement, formation of gummas- soft, non-cancerous growths (benign)
dysuria
purulent discharge in females, if untreated, cervicitis leading to PID (inflammation of the urethra uterus and fallopian tube)
transmission of STDs
through sexual intercourse or genital-oral contact
true/false chlamydia is an obligate intercellular bacterium that cannot reproduce itself
true
typical cause of STDs
typically by a virus or bacteria
Neisseria gonorrhea what type of lesions? incubation period? affects what?
(PID) gonacoccal may produce genital lesions incubation 2-7 days urethritis in males and females
what percentage of genital transmission occurs when asymptomatic and no noticeable lesion?
70%
what is the most common STD?
HPV
there are 2 types of herpes, what are they?
HSV-1- labial lesion, transmitted oral to oral contact and causes oral herpes HSV-2- genital lesion, sexually transmitted genital herpes
what is the most common bacterial STD?
Chlamydia
how many new cases of STDs per year how much of the US population will contract a STD before 35?
12 million 50%
with HPV what will happen 10% of the time?
10% will become chronically infected- at risk for cervical cancer - same strains can be oncovirusues
Syphilis is caused by
Treponema pallidum
