Ear infections, antibacterial therapy Flashcards
Otitis Externa:
Q: What is otitis externa, and what are the common bacterial culprits causing it?
A: Otitis externa is inflammation of the external ear canal. It can be triggered by a bacterial infection caused by Pseudomonas aeruginosa or Staphylococcus aureus.
Q: What’s the first choice of antibacterial therapy for otitis externa if Pseudomonas is suspected and there’s no penicillin allergy?
A: Ciprofloxacin (or an aminoglycoside).
Q: What’s the recommended antibacterial for otitis externa if there’s no penicillin allergy and Pseudomonas is not suspected?
A: Flucloxacillin.
Q: In case of penicillin allergy or intolerance, what’s the appropriate antibacterial therapy for otitis externa?
A: Clarithromycin (or azithromycin or erythromycin).
Otitis Media (in Children):
Q: What is acute otitis media, and what are the common pathogens responsible for it in children?
A: Acute otitis media is inflammation in the middle ear associated with effusion and an ear infection. It’s often caused by viruses (respiratory syncytial virus, rhinovirus, adenovirus, influenza virus, and parainfluenza virus) or bacteria (Haemophilus influenzae, Streptococcus pneumoniae, Streptococcus pyogenes, and Moraxella catarrhalis).
Q: In children with acute otitis media and no penicillin allergy, what is the recommended first-line antibacterial therapy?
A: First line: amoxicillin.
Q: What is the second-line antibacterial therapy for children with acute otitis media who experience worsening symptoms despite 2 to 3 days of treatment, and there’s no penicillin allergy?
A: Second line: co-amoxiclav.
Q: In children with acute otitis media and penicillin allergy or intolerance, what is the first-line antibacterial therapy?
A: First line: clarithromycin or erythromycin (in pregnancy).
Q: What is the second-line antibacterial therapy for children with acute otitis media who experience worsening symptoms despite 2 to 3 days of treatment and have penicillin allergy or intolerance?
A: Second line: consult a local microbiologist.
