Background: Nursemaid's elbow is a known orthopedic pediatric emergency that occurs between one and four years of age. Axial traction of the extended arm when the forearm is pronated is the most frequently reported mechanism of infliction. However, other mechanisms are mentioned in the literature. Cases report: We report a case of pulled elbow in a four-month-old child. The mother reported that the child only rolled over to her side. Conclusion: A high index of suspicion for pulled elbow should be kept in younger infants despite the absence of the usual presentation.

Background: Anaphylaxis is a life-threatening allergic reaction. Epinephrine is the first-line treatment of this condition. Kounis syndrome indicates the occurrence of acute coronary syndrome in a patient of hypersensitivity, allergy, or anaphylaxis associated with mast cells and platelets activation. Epinephrine can be the etiology of myocardial infarction in this setting. Cases report: This report represents a case of a 58-year-old female who had myocardial infarction while being treated of anaphylaxis in response to cefuroxime intake. Conclusion: Emergency physicians should be aware of the possibility of myocardial infarction in anaphylactic patients to properly manage it.
