Write answer in between .Q:A 56-year-old woman presents to the emergency department with severe pain in her legs. She has had these pains in the past but access to a doctor was not readily available in her remote village back home. She and her family have recently moved to the United States. She is seen walking to her stretcher with a broad-based gait. Ophthalmic examination shows an absent pupillary light reflex, and pupillary constriction with accommodation and convergence. What other sign or symptom is most likely present in this patient?? A: Negative Romberg sign, B: Deep tendon hyperreflexia, C: Painless ulcerated papules, D: Bells Palsy, E: Loss of vibration sensation,  <response>: This is a clinical vignette describing a 56-year-old woman with severe leg pain and findings on exam suggestive of a neurologic disorder. The history provides clues that she likely has a chronic condition that was not evaluated previously due to limited access to healthcare. The broad-based gait and absent pupillary light reflex suggest an upper motor neuron lesion. The additional finding of pupillary constriction with accommodation and convergence indicates the cranial nerves controlling these functions CN III and CN V are intact. This narrows down the localization to the spinal cord or brainstem. The question asks for the most likely additional sign or symptom. Choices A and D can be eliminated, as they describe peripheral nerve findings unrelated to the clinical vignette. Choice C describes skin findings in leprosy, which is not supported by the vignette. Choice E, loss of vibration sensation, is most consistent with an upper motor neuron lesion affecting the dorsal columns of the spinal cord. This is the most likely additional finding in this patient.E: Loss of vibration sensation
