Absolute neutrophil count <____ requires antibiotic prophylaxis<500
if platelet count is <____ spontaneous bleeding is possible20,000
There is a significant risk of transmission of HIV through aerosols generated during dental procedures, thus dentist and hygienists should use extra precautions when treating such patientsFalse
t/f: It may take as long as 15 years before an AIDS diagnosis is madetrue
t/f: HIV positive patients with NUP are 20.8 times more likely to have CD4+ cell counts less than 200 cells/mm3 compared to HIV positive patients presenting without NUP.True
t/f: There is a strong relationship between impaired renal function and incident CVD in HIV positive patients.true
t/f: All asymptomatic antibody-positive for HIV patients go on to develop AIDSfalse
t/f: There has been a significant decrease in the overall prevalence of oral lesions from 47-85% pre-ART to 32-46% post ARTtrue
t/f: A CD4+ count less than 200 cells/mm3 and a viral load greater than 3,000 copies/mL are two factors that predispose patients to the expression of oral lesionstrue
t/f: 3.6 million Americans, who have never been tested, are at risk for developing HIV. Of these 3.6 million Americans, 75% have been to a dental office within the last 2 years.true
t/f: Combination antiretrovirals are made up of at least 1 nucleoside reverse transcriptase inhibitor (NRTI) and a non nucleoside reverse transcriptase inhibitor (NNRT) or an integrase strand transfer inhibitor (INSTI) with a booster.false
t/f: True or False: HIV-positive patients with NUP were 20.8 times more likely to have CD4 counts < 200 cells/mm3 compared to HIV-positive patients presenting with NUPTrue
t/f: Undetectable viral load levels (HIV) could be 200-300 copies/mLFalse (undetectable load is <40 copies/mL)
t/f: Patients are instructed to discontinue warfarin treatment pre-operatively before extractions because it helps post-operative bleeding.False

student questions H&N cancers

Question Answer
t/f: According to the AJCC staging guide for treatment of cancer, Stage I and II cancers are treated with a SINGLE modalitytrue
patient with lesion consistent with oropharyngeal cancer, has had 10 sexual partners- what is prognosis (survival rate)could be oropharyngeal cancer, (if it is) survival rate 80%
t/f: 1. AJCC stages I and II are classified as more severe. 2. Recommended treatment includes dual/triple modality treatment.both false
t/f: Acute Radiation therapy toxicity includes xerostomiafalse (does include: Mucositis, Odynophagia, & Radiation dermatitis)
Which strand/s of HPV is responsible for oropharyngeal cancers?16 & 18
t/f: 1. When managing Head and neck cancer, cells are most sensitive to DNA damage before and during Mitosis. 2. This is also know as late G2 and M phases of the cell cycle.both TRUE
Pt presenting for HPV + OPSCC. The cause of the cancer is the result of E6 and E7 inactivation of ___ & ___p53 & Rb
What is the standard of care for Oral Cancer?Surgery of primary and regional Lymph Nodes
t/f: when providing radiation on a patient, we always use a square portal instead of shaping it to the desired planning target volume.false

What is the primary target of radiation?DNA
The term defined as repeated small doses of radiation to allow repair of subepithelilal damage is _____ ____Solution fractionation
t/f: being female is a risk factor for H&N cancersFalse
t/f: Fractionation can spare normal tissue by way of breaking up high doses of radiation, which allows recovery from sublethal damagefalse (low-dose)

t/f: Restoration of structure and function is a goal of oncological surgeryFalse
More than _________ oral sex partners increases risk of oropharyngeal cancer5
t/f: For Stage I/II head and neck cancer a single modality treatment such as radiation OR surgery is the treatment protocol. Stage III/IV is treated dual/triple modality treatment such as surgery + radiation + chemo or chemo + surgery.True
Oropharyngeal cancer prevalence is increasing due to HPV. The main pathway that HPV uses is _______ inactivate Rb and p53 tumor suppressors ultimately leading to an increase in ___________.E6 and E7, P16
True or False: Fractionating allows the patient to receive higher cumulative doses of radiation without exceeding acceptable toxicity. This technique moves the surviving cells/cumulative dose curve closer to that of the initial alpha curveTrue
