ABSTRACT

The success of immunotherapy in the treatment of patients with advanced melanoma has paved the way for unprecedented successes in the treatment of many other malignancies. We present a case of extensively metastatic oral mucosal melanoma that responded successfully to combined immune checkpoint blockade with ipilimumab and nivolumab but developed multiple immune-related adverse events, including myocarditis, a rare event associated with immunotherapy of elderly melanoma patients. Though the acute myocarditis was managed successfully, the patient succumbed to sudden cardiac death. This case highlights the fact, that autoimmune carditis must be considered when working up the sudden onset of shortness of breath in patients on immune checkpoint blockade. After controlling the acute myocarditis with high-dose steroids, which should be tapered over 6 weeks, further cardiology care is needed, and a defibrillator might have to be implanted. Understanding the pathophysiology of immune-related adverse events could make cancer immunotherapy both more effective and safer.

ABSTRACT

BACKGROUND: The authors evaluated the efficacy and tolerability of 10 percent and 20 percent benzocaine gels compared with those of a vehicle (placebo) gel for the temporary relief of toothache pain. They also assessed the compliance with the label dose administration directions on the part of participants with toothache pain. METHODS: Under double-masked conditions, 576 participants self-applied study gel to an open tooth cavity and surrounding oral tissues. Participants evaluated their pain intensity and pain relief for 120 minutes. The authors determined the amount of gel the participants applied. RESULTS: The responders' rates (the primary efficacy parameter), defined as the percentage of participants who had an improvement in pain intensity as exhibited by a pain score reduction of at least one unit on the dental pain scale from baseline for two consecutive assessments any time between the five- and 20-minute points, were 87.3 percent, 80.7 percent and 70.4 percent, respectively, for 20 percent benzocaine gel, 10 percent benzocaine gel and vehicle gel. Both benzocaine gels were significantly (P ≤ .05) better than vehicle gel; the 20 percent benzocaine gel also was significantly (P ≤ .05) better than the 10 percent benzocaine gel. The mean amount of gel applied was 235.6 milligrams, with 88.2 percent of participants applying 400 mg or less. CONCLUSIONS: Both 10 percent and 20 percent benzocaine gels were more efficacious than the vehicle gel, and the 20 percent benzocaine gel was more efficacious than the 10 percent benzocaine gel. All treatments were well tolerated by participants. Practical Implications. Patients can use 10 percent and 20 percent benzocaine gels to temporarily treat toothache pain safely.
