ACMT Toxicology Visual Pearls: Toxic Mouth Pain
A middle-aged Asian female presents to the emergency department complaining of 2-3 days of mouth pain. She has chewed betel nut for a number of years. Which of the following is true regarding her presentation and management?
- Debridement should be avoided.
- Metronidazole is contraindicated due to the potential of a disulfiram-like reaction.

Regional nerve blocks of the face and ear can be a wonderful choice of analgesia in a child, particularly for wounds that need to be repaired. The benefits include fewer local injections, improved cosmesis due to less wound margin distortion, and improved analgesia within the nerve region.
While ear foreign bodies can happen at any age, the majority occur in children less than 7 years of age.
Epistaxis is a common presentation to the emergency department (ED)
The management of a dental fracture is a core skill of the emergency physician.
Ear irrigation is an important tool for adult and pediatric patients in the Emergency Department (ED) with ENT complaints. Irrigation can be used to clear ear cerumen, visualize tough-to-see tympanic membranes, and remove foreign bodies. This may reduce the need for subspecialist care and improve the patient’s hearing and quality of life.
