OBJECTIVE Vitamin E (alpha-tocopherol), a free-radical scavenger, has been reported to improve symptoms of tardive dyskinesia. The authors attempted to replicate this finding under more controlled conditions in a larger study group. METHOD Fifteen inpatients and six outpatients with tardive dyskinesia received up to 1600 IU/day of vitamin E for 6 weeks in(More)
PURPOSE, PATIENTS, AND METHODS The classic agent for cutaneous leishmaniasis is pentavalent antimony. However, there are no reports of the efficacy of antimony versus placebo or of the efficacy of any alternative therapy versus either antimony or placebo. In the present report, the oral antifungal agent ketoconazole (600 mg/day for 28 days) was compared to(More)
We studied the prevalence of Toxoplasma antibody over a 10-year period in a rural population of 326 people in Chorrera Province of Panama using the dye test. Fifty-five seroconversions were found in 108 people at risk, and 48 (87%) in children between 2 and 13 years with a mean incidence rate of 8.6% per year. Antibody prevalence rose from 25% at 5 years to(More)
Experimental ischemia models have shown the antitussive dextromethorphan to be an N-methyl-D-aspartate antagonist with neuroprotective properties. We treated 10 patients with a history of recent stroke or transient ischemic attack with oral dextromethorphan (60 mg q.i.d.) for 3 weeks in a placebo-controlled, double-blind, crossover tolerance study. We(More)
We tested the World Health Organization (WHO) recommended treatment for mucosal leishmaniasis in 16 Panamanians with disease due to Leishmania braziliensis panamensis. Disease was mild in this population because it was limited to the nasal mucosa and only one patient had septal perforation. The patients were administered 20 mg antimony (in the form of(More)
From November 1985 to December 1988, 33 patients were enrolled at Santo Tomas Hospital and Gorgas Memorial Laboratory to study the etiology, epidemiology and clinical characteristics of mucocutaneous leishmaniasis. Seventeen were males and 16 females, 14 to 80 years old from the endemic rural areas of the provinces of Panama, Colón, Coclé, Darién, Veraguas,(More)
Twelve patients with a history of cerebral ischemia were randomized to treatment with the N-methyl-D-aspartate antagonist dextromethorphan (60 or 90 mg p.o. q.i.d.) or placebo for 2 weeks in a randomized, safety study. Neuropsychological testing did not detect evidence of cognitive dysfunction; however, side effects including lightheadedness, drowsiness,(More)
Eighteen patients received 1,250 mg of allopurinol riboside (AR) four times daily for 28 d. Nine of the patients concurrently received 500 mg probenecid (PB) four times daily. Cure was assessed clinically and parasitologically. Patients who had culture-positive and nonhealing lesions 3 mo after therapy received pentavalent antimony. Of the nine patients who(More)
