The anti-arrhythmic activity of mexitil was studied in 36 patients with frequent, prognostically unfavourable ventricular extrasystoles of various etiology. Quantitative and qualitative assessment of rhythm disorders was accomplished by bicycle ergometry and ECG recording for 24 hours by means of portable monitors. The disorders of rhythm were appraised prior to treatment, during mexitil medication in daily doses of 750--1200 mg/24 hrs administered for 3--5 days, and against the background of placebo. The effect of a single 250 to 600 mg dose of mexitil was appraised by monitoring the ECG for three and a half hours. The concentration of mexitil in blood plasma and saliva was tested by gas-fluid chromatography. A positive effect of mexitil treatment manifested in complete correction of ventricular extrasystoles or the reduction of their number by more than half and complete elimination of group extrasystoles and paroxysms of ventricular tachycardia was produced in 66 per cent of patients according to the daily ECG monitoring finds and in 76 per cent of patients according to the results of bicycle ergometry. The antiarrhythmic effect developed 62 minutes, on the average, after oral administration of a single 250--600 mg dose of mexitil and lasted 5--8 hours and more. The therapeutic concentration of mexitil ranged from 0.6 to 0.9 micrograms/ml in blood plasma and from 10.3 to 15.8 micrograms/ml in saliva. In 36 per cent of patients side effects (mainly muscular tremor, lassitude and headache) were noted. It is concluded that mexitil possesses high anti-arrhythmic activity in ventricular extrasystole. To avoid side effects it is recommended to begin treatment in a dose of 250 mg given three times daily, and if necessary gradually increase the single dose to 400 mg and the daily dose to 1200 mg.

The first report in the literature of opsoclonus in malaria was presented. A 24-year-old woman had a two week history of high fever and lassitude. Physical examination revealed no specific neurological sign on admission. Ring form and gametocytes of Plasmodium falciparum were found in blood smear. Combined treatment of quinine and tetracycline were prescribed. She developed classical abnormal eye movement of opsoclonus and hand tremor on the following day, which gradually subsided on the tenth hospital day. Computed brain tomography and cerebrospinal fluid study were normal. She was discharged home after 3 weeks of admission with some occasional minimal opsoclonus without hand tremor.

Metoclopramide antagonizes the effect of dopamine in the central nervous system and other organ systems. Metoclopramide's effect on the medullary chemoreceptor trigger zone makes it useful as a routine anti-emetic and in preventing vomiting induced by antineoplastic drugs, particularly cisplatin. Metoclopramide's gastrointestinal smooth muscle stimulatory effects are related to its ability to antagonize the inhibitory neurotransmitter, dopamine; to augment acetylcholine release and sensitize the muscarinic receptors of the gastrointestinal smooth muscle; and to coordinate gastric-pyloric-small intestinal motor function. The indications for which metoclopramide is approved in the United States are reviewed. Adverse effects, which may occur in up to 20% of patients, include drowsiness, lassitude, and akathisia; all are usually mild, transient, and reversible. Tremor, dystonic reactions, and extrapyramidal effects are infrequent; breast enlargement, galactorrhea, and menstrual irregularities are related to prolactin release.

In a previous study, we speculated that some of the high mercury levels observed in head hair from a total of 14 subjects who resided around Lake Victoria, Tanzania, might be attributable to the habitual use of toilet soap containing considerable amounts of mercury (Harada et al. Sci Total Environ 1999;227:249-256). In August 1998, the current study was conducted to investigate if such mercury-containing soap was also available in the surroundings of Lake Victoria, Kenya, and if so, its toxic effects. A total of nine goldminers, 44 fishermen and their families, and 12 residents of Kisumu City, Kenya, volunteered for the study. Fourteen types of toilet soap were collected in Kisumu. Total mercury content was very significantly higher than in European-made soap (0.47-1.7%, as mercury iodide) compared with Kenya-made soap (0.41 x 10(-4)-6.2 x 10(-4)%). Indeed, all the subjects with a high hair mercury level (> 36.1 ppm) had made habitual use of European-made soap, accompanied by various symptoms, such as tremor, lassitude, vertigo, neurosthenia, and black and white blots, suggesting inorganic-mercury poisoning. On the other hand, any subject who had used soap other than the European-made soap, did not exceed a mercury level of 10 ppm in hair that is well within normal limits (Harada et al. Sci Total Environ 1999:227:249-256). The findings obtained suggest that the mercury-containing soap must be barred from circulation without delay, and that the residents' health in addition to the environmental pollution in Lake Victoria (Kenya as well as Tanzania) should be kept under close observation.

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.
