Chalmydia trachomatis (gram - bacteria) STD
31
What is the most common REPORTABLE STD in the U.S.?
Chlamydia
32
What will the infection of Chlamydia in adolescence increase the risk of?
cervical CA
33
What causes chronic lymphatic infection, genital lesion, and bubo* in the groin?
Lymphogranuloma venereum
34
What organism causes Lymphogranuloma venereum? How does one get it?
a different strain of Chlamydia trachomatis (so it doesn't cause chlamydia) STD
35
What causes small, painless nodules, then when open, is fleshy, oozing lesions called "beefy red lesion"?
Granuloma inguinale
36
What organism causes Granuloma inguinale? How does one get it?
Klebsiella granulomatis (gram - bacteria) STD
37
T/F. Granuloma inguinale is the same as lymphogranulomas venereum.
False-- they are NOT the same Granuloma inguinale--> "beefy-red lesion" lymphogranulomas venereum--> bubo in groin
38
What STD has 4 stages (3 of those being clinical)? What are they?
Syphilis 1. Primary--> painless chancre 2. Secondary--> widespread rash 3. Latent--> 2/3 do not progress 4. Tertiary --> dementia and gummas
39
What organism causes Syphilis? What should we remember about this organism? How does one get it?
Treponema pallidum pallidum (gram - bacteria) --> is a spirochete STD; also mother to child (occurs worldwide)
40
What will mother to child transmission of Syphilis result in?
congenital syphilis
41
Can Syphilis be treated?
Penicillin G can be used to Tx it in Primary or Secondary stage; but once it reaches the tertiary stage it CANNOT be Tx
42
Which stage of Syphilis is characterized by a widespread rash that has no pain or itching?
Stage 2: Secondary Stage
43
What stage of Syphilis does it go Latent? How often does an ind. just stay in this stage?
Stage 3 about 2/3 stay here and 1/3 progress into stage 4: Tertiary
44
What stage of Syphilis will cause painless, reddened chancre? When do these occur after infection?
Stage 1: primary occurs at site of inf. ~ 10-21 days following exposure
45
What stage of Syphilis can effect any organ/tissue and causes dementia and gummas?
Stage 4: Tertiary ~1/3 cases progress to this from the Latent stage
46
What STD causes soft chancres that are painful?
Chancroid
47
What are the symptoms in males and females in someone with Chancroid?
soft chancres that are painful women are often asymptomatic
48
What organism causes Chancroid? How does one get it?
Haemophilus ducreyi (gram - bacteria) STD (most cases in US are due to foreign travel)
49
What should we remember about the difference between the chancre occurring in Syphilis and Chancroid?
Syphilis--> painless (more red, usually 1 or 2) Chancroid--> painful (more white, usually a cluster)

ass. with cervical cancer and oropharyngeal cancer
58
How many cases per year is HPV in women ass. with cancer? What cancer is MC?
20,000+ HPV-ass. cancers MC = cervical cancer
59
How many cases per year in males is HPV ass. with cancer? What caner is the MC?
11,000+ HPV-ass. cancers MC = oropharyngel cancer
60
T/F. AIDS is a disease.
False-- it is NOT a disease; it is a SYNDROME
61
What organism causes AIDS?
Human Immunodeficiency Virus (HIV)
62
How can one get AIDS?
- found in blood, semen, saliva, vaginal secretions - breast milk - must be introduced into body via sexual activity, tear, or lesion in skin or mucous membranes or injected into body
63
What is the most well known retrovirus?
HIV
64
T/F. If someone is HIV positive that means they have AIDS.
False-- it does not mean they have AIDS
65
How is AIDS Dx?
ELISA/Western Blot tests
66
What is the cancerous tumors of CT that is associated with AIDS and has a bluish-red or purple bumps with it?
Kaposi's Sarcoma
67
How organism causes Kaposi's Sarcoma? How does one get this?
Human Herpes Virus (HHV-8) aka Rhadinovirus opportunistic inf seen primarily in AIDS patients (rarely see in immunocompenent inds)
68
