Autopsy revealed pericardial abscess posterior to the LA in communication with the esophagus. Extension to the LA was not seen. Conclusion While the surgical treatment of AEF is relatively well established, there is no consensus in the management of PEF. While prior small series have suggested PEF may be managed with esophageal stenting, our case illustrates the limitations of this approach.The effectiveness of AbobotulinumtoxinA (BoNT-ABO) depends on numerous factors, including the amount of dose, presence of autoantibody and number of injected muscles. In this study, we aimed to investigate the effect of the BoNT-ABO in different dilutions, age groups, and frequency of sessions. A total of 60 patients with upper facial wrinkles were included in the study. A 500-unit vial of BoNT-ABO was reconstituted with 2.5 mL preservative-free normal saline for 30 patients and 4 mL saline for the other 30 patients for injection. There was no statistically significant difference between 2.5 mL (4.8 ± 2.08 months) and 4 mL (4.2 ± 1.72 months) group in terms of duration effect of BoNT-ABO (P = 0.228). There was no significant difference mean duration of effect between the age at ≤40 and > 40 years for each dilutions containing 2.5 and 4 mL. (P = 0.856, P = 0.966, respectively). There was no correlation between the number of sessions and the duration of the effect (P = 0.229, C = -0.158). In conclusion, although differences were not statistically significant, the 2.5 mL dilution of the BoNT-ABO seems to have a longer effect than 4.0 mL dilution. The low number of sessions of BoNT-ABO and patients with ≤40 years of age do not have a remarkable longer duration of the effect of BoNT-ABO. This article is protected by copyright.
