The patient was the front seat driver in a head-on collision which resulted in a femur and pelvic fracture which was treated appropriately. The patient spent 3 weeks in the hospital and was then discharged 2 weeks ago. The patient has a past medical history of diabetes, hypertension, and dyslipidemia. He smokes 3 packs of cigarettes per day and drinks 4 alcoholic beverages every night. The patient says that he has been attempting to engage in sexual activities with his wife but has been unable to do so. He states this has never been a problem for him before. He also reports new-onset minor headaches and trouble sleeping for which he is taking trazodone. Which of the following is the most likely diagnosis?? A: Atherosclerotic change, B: Increased prolactin, C: Medication changes, D: Neurologic damage, E: Psychologic,  <response>: This is a clinical vignette describing a 62-year-old man who was recently in a car accident resulting in fractures, hospitalization, and now erectile dysfunction. The key details are his age, trauma history, past medical history of diabetes, hypertension, dyslipidemia, heavy smoking, and alcohol use. His new symptoms are erectile dysfunction, headaches, and insomnia after the accident. The choices describe potential causes of his erectile dysfunction. Choice A seems unlikely as atherosclerosis would be a chronic process less likely to cause acute onset erectile dysfunction. Choice B can be ruled out as there is no indication of prolactin issues. Choice C is plausible as medications started after the accident could potentially cause side effects like erectile dysfunction. Choice D stands out as neurologic damage from the trauma seems the most likely cause of his new acute erectile dysfunction. Choice E is less likely than neurologic causes but still possible if the trauma has caused psychologic distress impairing sexual function.D: Neurologic damage
