student questions AIDS

Question Answer
What two drugs are typically used to treat ANUG?Metronidazole + Augmentin

For severe oral/esophageal candida infections, what agent should be used?Fluconazole
t/f: For AIDS patients, Antibiotic prophylaxis should not be indicated to protect patients from post op infectionsFalse
T/F: 25% of patients with renal disease are more likely to develop cardiovascular attacks, such as MI or stroketrue
The most common worldwide oral manifestation of HIV infection is ______Candidiasis
T/F: Patients that have been exposed to the AIDs virus and are HIV-seropositive, but asymptomatic may receive all indicated dental treatment.True
Which drugs if any are recommended to discontinue for a patient to continue with general dental procedures?none
t/f: HIV/AIDS- Oral lesions correlate with HIV viral load, and don't change with ART.True
t/f: INR 3-4 is ideal for pts on anticoagulantFalse
CD4 <____ cells is diagnostic of AIDS<200
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 unit of absorbed radiation dose in radiation tx?Gray
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)
Cells are most sensitive to DNA damage during what stage?Mitosis
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
t/f: Oropharyngeal cancer is the only head and neck cancer with increasing incidence (except thyroid cancer, which is not a true increase). Oropharyngeal cancer is increasingly associated with Human Papillomavirus, rather than traditional risk factors.True
According to AJCC Staging, which stage involves vocal cord fixation, paraglottic space involvement, or invasion of inner cortex of thyroid cartilage?T3
t/f: Branchial cleft cysts that appear in the neck are common in patients over the age of 25 years old.False
The following symptoms describe (acute/late-stage) radiation toxicity: Dysphagia, xerostomia, skin fibrosis?Late-stage
Besides thyroid cancer, what cancer has a increase in incident rate over the past few years?Oropharyngeal
AJCC T3 is associated with size over ____ cm>4 cm
t/f: Parotid gland cells are not as affected by radiation as other cellsfalse
t/f: T1-T2 staged oral cancer would require removal of regional lymph nodesFalse
t/f: candiasis is a sign of oral cancerFalse
Most common sites for cancer in the head and neck are ____ and ___ of ___Tongue & FOM
A patient arrives in your office with laryngeal cancer that involves impaired cord mobility and extension into the supraglottis. Which treatment should be performed?Transoral laser surgery or XRT
What is the most common site for Squamous Cell Carcinoma in the oral cavity?Lip
