A 19-year-old left-handed man, who was raised by deaf-mute parents and learned sign language concurrently with normal speech, sustained a traumatic cerebral contusion. He subsequently had no evidence of apraxic, visual-spatial, or sensorimotor deficits of the left limbs with which he was accustomed to use signs. Globally aphasic with a dense right hemiparesis, he initially recovered sign language to a greater degree than spoken language with a reversal on follow-up observations. Receptive skills improved to a greater degree than expressive skills with no marked difference between verbal and sign language, but with natural signs better preserved than finger spelling.
A young man with dermatitis herpetiformis developed fatigue and neurologic complaints 4 years after he began oral dapsone therapy. Neurologic examination and nerve conduction studies confirmed the presence of a combined motor and sensory peripheral neuropathy. The symptomatic improvement reported by the patient was supported by improvement in the nerve conduction studies after cessation of dapsone therapy. Substitution of sulfapyridine did not adversely affect the resolution of his neuropathy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
