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

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
