Flashcards in Acute Pharyngitis Deck (26):
1

Most important agents causing pharyngitis

1) Viruses 2) GABHS

2

Major virulence factor for GABHS

M protein

3

Virulence factor of GABHS that facilitates resistance to phagocytosis by PMNs

M protein

4

Prominent sore throat and fever in the absence of cough

Acute pharyngitis

5

Pharynx is red, tonsils enlarged and clasically covered with a yellow blood-tinged exudate

Strep pharyngitis

6

Petechiae or doughnut lesion on the soft palate and posterior pharynx

Strep pharyngitis

7

Bacterial vs viral pharyngitis: Rapid onset

Bacterial

8

Bacterial vs viral pharyngitis: Gradual onset

Viral

9

Bacterial vs viral pharyngitis: Rhinorrhea, cough, diarrhea

Viral

10

Bacterial vs viral pharyngitis: Concurrent conjunctivitis and fever

Viral, specifically adenovirus

11

Bacterial vs viral pharyngitis: Small grayish vesicles and punched-out ulcers in the posterior pharynx

Viral, specifically Coxsackie herpangina

12

Bacterial vs viral pharyngitis: Small yellowish-white nodules in the posterior phraynx

Viral, specifically Coxsackie acute lymphonodular pharyngitis

13

Septic thrombophlebitis of the IJV with septic pulmonary emboli, producing hypoxia and pulmonary infiltrates

Lemierre syndrome

14

Lemierre syndrome is a serious complication of

F. necrophorum pharyngitis

15

Gold standard for diagnosing strep pharyngitis

Throat culture; an IMPERFECT gold standard

16

T/F Rapid test to detect group A strep antigen is highly specific, so if a rapid test is positive, throat culture to diagnose strep pharyngitis is unnecessary and appropriate treatment is indicated

T

17

T/F Most untreated episodes of strep pharyngitis resolve uneventfully in a few days

T

18

T/F Early antibiotic therapy for strep pharyngitis hastens clinical recovery

T, by 12-24hrs

19

Primary benefit of treatment of strep pharyngitis

Prevention of ARF

20

Early antibiotic therapy for strep pharyngitis successfully prevents ARF if treatment is instituted within

9 days of illness

21

T/F GABHS remains universally susceptible to Penicillin

T

22

Treatment regimen most effective for eradication of streptococcal carriage

Clindamycin

23

If compliance with antibiotic treatment for strep pharyngitis has been poor, ___ is suggested

IM benzathine penicillin

24

Lowers incidence of pharyngitis for 1-2 yrs among children with recurrent culture-positive GABHS pharyngitis that has been severe and frequent

Tonsillectomy

25

Frequent pharyngitis is defined as

>7 episodes in a year, or >5 in EACH of the preceding 2 years

26

T/F Viral respiratory infections can predispose to bacterial middle ear infections
