Thirty-eight workers from a factory producing nickel-cadmium and other types of batteries came to us for medical evaluation. They included 21 women and 17 men (seniority 2-20 years, age range 31-63 years), and represented a self-selected subset of 700-900 ever-employed and 200+ recently or currently employed workers in the factory. Thirty-four worked on the nickel-cadmium assembly line. Symptoms and signs included: headache in 34; weakness, fatigue and lassitude in 26; dizziness in 16; pruritus and skin eruptions in 37; gingivitis, teeth loss and caries in 34; nasal congestion, nosebleeds and anosmia in 30; cough, phlegm production, wheezing and shortness of breath in 26; "asthma" in 14; bone pain in 18; urinary frequency, beta 2 microglobulinuria and kidney stones in 17; and sterility or multiple abortions (33) in 8 of 21 women. One additional patient had died from an "amyotrophic lateral sclerosis-like syndrome", while CT scans in six workers revealed brain atrophy. One other worker had leukemia, and two had died from cancer (lung and pancreas). Those who had worked for more than 10 years had more symptoms and signs than shorter-term employees, especially neurological illness, bone pain and urinary tract problems, including beta 2 microglobulinuria. Past blood and urinary cadmium levels were in the range of 1.6-8.7 micrograms/dl and 8-306 micrograms/l, respectively. Our findings indicated that: a) health risks for workers were not confined to the nickel-cadmium assembly line or to older workers, b) hazardous exposures still existed and illness appeared in new workers after a clean-up and intervention program, and c) exposures involved increased risks for renal disease and cancers. Finally, there is a need to control exposures and determine health risks in the full cohort of those ever employed, in the workers' children, and in the surrounding environment (air, ground, water) due to the dumping of waste from the plant.

Coma, hemiparesis, unilateral optic neuropathy, and anosmia manifested in a patient with leukemia after he received only three courses of intravenous high-dose cytosine arabinoside (ARA-C). The patient's mental status returned to normal after several days, and his hemiparesis resolved. However, the visual loss persisted, and near complete visual loss in the other eye ensued over the following month. Severe bilateral optic atrophy appeared as the visual loss progressed. Anosmia became evident after resolution of the coma and did not improve. The patient had previously had a thoracic myelopathy 2 weeks after receiving low-dose i.v. ARA-C. The neurotoxicity of high-dose i.v. ARA-C may arise at much lower cumulative doses than has been reported. In addition to cerebellar dysfunction and somnolence, high-dose i.v. ARA-C may produce optic neuropathy, anosmia, and hemiparesis.
