Cerebral metabolic dysfunction in AIDS: findings in a sample with and without dementia.

Positron-emission tomography was coupled with neurological and neuropsychological evaluation to study regional cerebral activity and neurologic status in two groups. Seventeen patients with full-blown AIDS and 14 seronegative control subjects were studied using [18F]2-fluoro-2-deoxy-D-glucose in a resting state. The AIDS group had relative regional hypermetabolism in the basal ganglia and thalamus; stepwise multiple-regression analyses revealed a significant relationship for the AIDS group between temporal lobe metabolism and severity of dementia on the AIDS Dementia Complex Rating Scale. These results suggest that the basal ganglia, thalamus, and temporal lobes are differentially affected in AIDS.

Subclinical neuropathy associated with chronic obstructive pulmonary disease: possible pathophysiologic role of smoking.

Twenty of 23 patients with chronic obstructive pulmonary disease (COPD) showed electrophysiologic evidence of peripheral nerve dysfunction. Abnormalities of sensory nerve conduction were most common, affecting the sural nerve (20 subjects), ulnar nerve (11), radial nerve (eight), and median nerve (seven). Six subjects had impairment of both sensory and motor nerve function, with the common peroneal being the most frequently affected motor nerve. Clinical signs of neuropathy were found in four patients. Cigarette smoking, expressed as pack-years, was correlated significantly with the electrophysiologic abnormalities. These findings indicate that subclinical polyneuropathy commonly occurs in association with COPD and that this COPD-related neuropathy is correlated with cigarette consumption. From these data we suggest that a substance or substances in cigarette smoke, such as nicotine, taken on a long-term basis, may be toxic to peripheral nerves.
