Cancer
cervical carcinoma
KS
Cervical carcinoma
HPV
Kaposi
KSHV (HHV 8)
22 y/o small raided lesions on cervix asymptomatic (no pain) Many partners labial veneral warts and friable erythematous cervix
HPV caused genital warts
Single best screening procedure available for cervical cancer
Pap smear
Tests used to test samples from a pelvic exam for presence of dangerous HPV TYPES in women >30 years
PCR
Is HPV curable?
No
Genital warts can be removed but virus causing them remains with you. It’s possible for virus to resolve itself but it’s unpredictable.
VF of HPV
Oncogenes in malignant types (16 and 18)
DS DNA virus w/ a circular genome
HPV (Papovaviridae)
infects epithelial cells of host that are in S phase>
local replication>
benign outgrowth of cells into GENITAL WARTS
HPV
cervical cancer associated w/ HPV
cervical carcinoma
48 hr painful urination
yellowish penile discharge
multiple partners
N. Gonorrhoeae
*typically has purulent discharge
Testing for N. gonorrhoeae?
Gram stain of urethral discharge*
DNA probes for PCR tests
ELSA- protein/Ab against bacteria
Gram - diplococci that is OXIDASE + and a glucose oxidizer
N. Gon
Specialized pilli for attachment to mucosal surface
Endotoxin
IgA protease
N. Gonn
Antigenic variation specialized pilli allows this bacteria to evade host host defenses and prevents killing by phagocytosis
N. Gonn
How does N. Gon cause urethritis in men and cervicitis in women?
N. gon attches via pili to mucosal cells or urethra or vagina> evades mucosal Abs w/ IgA protease> endocytosed> kills ciliated cells> Inflammatory response> Urethritis/cervicitis
N. Gonn that progresses to uterus, fallopian tubes or ovaries
PID> increased risk of ectopic preg
N. Gonn that progresses from fallopian tubes to peritoneal cavity and leads to peritonitis and infection of the liver capsule
Fitz- Hugh Curtis Syndrome
