Photosensitivity after 5-ALA administration is a known side effect, but a photosensitivity reaction from operating room lights has not yet been documented. We report the case of a 56-year-old man with a history of previous resection of a grade II astrocytoma who presented with imaging concerning for tumor recurrence and possible malignant transformation. Repeat surgical resection utilized 5-ALA. Soon after the surgery, he developed reddening of his skin, particularly over the right side of his head and neck, with blistering and peeling in a distribution that was particularly exposed to operating room lights during surgery. No other areas of his skin experienced the same redness, blistering, or peeling. Topical lotions were applied and the skin changes resolved spontaneously over weeks. Significant photosensitivity after administration of oral 5-ALA is a rare complication, but neurosurgeons who perform fluorescence-guided tumor resection should remain cognizant of its potential association with exposure to intense light, including in the operating room. Phototoxicity typically is self-limited, but awareness is important to minimize its occurrence.A 44-year-old woman with a history of factor V Leiden deficiency and recurrent pulmonary emboli was diagnosed with coronavirus disease 2019 (COVID-19) three weeks prior presented to her local ED with severe chest pain. She was found to have a large hemorrhagic pericardial effusion by cardiac MRI with echocardiographic signs of tamponade. She underwent the creation of a pericardial window and was treated with colchicine with improvement in symptoms.Aim Anxiety is an emotion recognized by a feeling of tension
