Q

A 7 y/o male presents to the clinic. His mother says he hasn’t been eating normally because he can’t swallow his food but his throat doesn’t hurt. She also says that this has happened before. On examination you find red, swollen tonsils with a purulent exudate. You peel away a white, thin membrane which does not bleed. What does this patient most likely have? How will you treat it?

A
  • Tonsillitis

- Tonsillectomy (usually penicillin would be treatment but since he has had this before, he will need it removed)

31
Q

What is the treatment for tonsillitis?

A
  • Penicillin (for streptococcal infection)
  • Rest
  • Fluids
  • Salt-water gargle
  • Humidified air
  • Zinc lozenges
32
Q

What organisms cause peritonsillar abscesses?

A
  • Group A beta-hemolytic Streptococcus

- Anaerobes, such as Bacteroides

33
Q

A 17 y/o female presents to clinic with fever, severe pain on swallowing, and trismus. While she is telling you what’s wrong, it sounds like there is a hot potato in her mouth causing a muffled sound. On examination, the palate is erythematous and the tonsils are asymmetric.

A

Peritonsillar abscess

34
Q

True or false: A patient with peritonsillar abscess will have his head tilted away from the affected side and the uvula may be displaced towards the affected side.

A

False

Head will be tilted toward affected side / Uvula will be displaced to the opposite side

35
Q

What is the treatment for peritonsillar abscess?

A
  • IV penicillin over 24-48 hours
  • When pain goes down, I&D
  • Tonsillectomy after acute infection has been resolved (because these abscesses tend to recur)
36
Q

How long must sinusitis occur to be considered chronic?

A

More than 12 weeks

37
Q

Sinusitis is typically precipitated by what two things? What do these cause?

On examination, scattered rhonchi and wheezing were noted. What is the most likely diagnosis? What medication will you prescribe?
