The deposition of copper on Descemet's membrane and the anterior and posterior lens capsule with extreme hypercupremia and IgG hypergammaglobulinemia has been previously described with multiple myeloma and pulmonary carcinoma. A 66-year-old man presenting with blurred vision was found to have bilateral golden-brown metallic dust-like deposits on the central region of Descemet's membrane and the anterior and posterior lens capsule. Laboratory investigations revealed an elevated serum copper level 10 times the normal level associated with a monoclonal gammopathy and a normal ceruloplasmin level. Copper binding to the serum proteins was investigated by three biochemical methods. The results demonstrated that the major copper binding fraction in the serum was IgG. N-terminal amino acid analysis of the IgG did not find the sequence of Asp-Ala-His, which has been shown to be a copper binding site in albumin. This is the first report of benign monoclonal gammopathy being associated with the ocular deposition of copper.

This survey is part of a more comprehensive study on the health consequences of pesticide exposure. In the county (municipality) of Paty do Alferes, Rio de Janeiro State, Brazil, 55 agricultural workers were interviewed on the use of pesticides, use of personal protective equipment, data on health status, and symptoms related to pesticide exposure, disposal of agrochemical containers, and technical assistance. The most widely used pesticides were insecticides such as abamectin, organophosphate compounds, and pyrethroids, and fungicides such as mancozeb, chlorothalonil, and copper products. As a rule, pesticides are handled carelessly, and 92% of workers involved in the mixing, loading, and spraying of insecticides and fungicides used no protective clothing or equipment whatsoever. Some 62% of workers reported at least one illness associated with mixing or spraying pesticides. The most frequently reported symptoms were headache, nausea, vomiting, dizziness, skin irritation, and blurred vision, and 21% of affected workers required medical care. In more than half (51%) of the cases, workers reported using organophosphate insecticides from toxicological class I when they felt sick.

Headache makes one of the most common side effects of frequently pesticide application. This is to be taken care of in rural areas. Headaches have been reported with the use of ivermectin, ivermectin-diethylcarbamazine, organophosphates, and also with the fungicide maneb and copper sulfate, carbofuran, hexonal, dioxin, methomyl and its salts, as well as rare cases of poisoning with the fungicide combination of propineb and cymoxanil. Headache often occurs after long term work with pesticides and/or in laboratories. There are numerous symptoms accompanying headache in pesticide poisoning the most common being elevated body temperature, lassitude, dizziness, irritability, nausea, vomiting, epigastric pain, diarrhea, myalgia, pains in the arms and legs, sleepiness, pains in joints, irritation of eyes/face/skin, sweating. Much less common are respiratory disturbances, tachycardia, tachypnea and other cardiac distur bances, fall of blood pressure, gastrointestinal discomforts, constipation, poor appetite, significant decrease in leukocyte count, anemia, albuminuria, azotemia, fasciculations, miosis, blurred vision, memory disturbances and other neurologic disturbances, postural tremor, signs of cerebral function damage, bradykinesia, etc.
