Within two months of treatment for falciparum malaria, Plasmodium vivax infections developed in 58 (33%) of 174 patients who had received a quinine or quinidine regimen and in 46 (32%) of 145 patients who had received mefloquine with inpatient follow-up of more than six weeks. The time to vivax relapse was significantly longer after mefloquine treatment(More)
The efficacy of low dose chloroquine, characteristic pattern of relapse and the relapse rate in vivax malaria after high dose primaquine were investigated in 167 Thai patients. 87 patients were allocated at random to receive 300 mg, and 80 received 450 mg of chloroquine on the first day of admission. All patients in both groups showed a rapid response with(More)
The standard six-dose intramuscular (i.m.) rabies post-exposure vaccine regimen using a new purified chick embryo cell (PCEC) vaccine was compared with two economical multisite intradermal (i.d.) PCEC regimens, a multisite i.m. PCEC schedule and a subcutaneous regimen using a suckling mouse brain (SMB) rabies vaccine manufactured in Thailand. The(More)
Healthy volunteers were randomized to receive either intradermal purified chick embryo cell rabies vaccine (PCEC) alone (0.1 ml at each of two sites on days 0, 3 and 7, and at one site on days 28 and 90) (n = 81), or intradermal PCEC with one dose of human rabies immunoglobulin (HRIG) intramuscularly at 20 IU kg-1 on day 0 (n = 52).

Pharmacokinetics of quinine, quinidine and cinchonine when given as a combination were evaluated in Thai patients with falciparum malaria during acute infection and convalescence. The combination of quinine, quinidine and cinchonine was randomly given to thirteen patients at 400 mg or 600 mg (consisting of one-third of each component; 7 patients were(More)
At a time when Fansimef, the fixed combination of mefloquine, sulfadoxine and pyrimethamine was considered for prophylaxis of falciparum malaria, a randomized double-blind study comparing the efficacy and tolerability of Fansimef with that of Lariam (mefloquine), Fansidar, chloroquine and placebo in malaria prophylaxis was performed in Thailand from July(More)
Human gnathostomiasis is characterized by space-occupying inflammatory lesions and/or hemorrhage as a result of the migration of, very often, a single larva of Gnathostoma spinigerum. Intermittent cutaneous migratory swellings occurring over years is the most common manifestation and the rare cerebral invasion may be fatal. There are currently no effective(More)
Plasmodium falciparum in Southeast Asia is highly resistant to chloroquine and sulfadoxine/ pyrimethamine. Quinine-tetracycline has been used as a second line treatment for uncomplicated falciparum malaria, but duration of treatment varies from place to place. The 7-days course of this combination has been shown to be very effective. However, due to the(More)
The incidence and progression of coagulation abnormalities were studied in 52 patients with acute falciparum malaria. The patients were prospectively divided into 3 groups; severe (parasitaemia greater than or equal to 5% or vital organ dysfunction), 12 patients; moderate (parasitaemia 1%- less than 5% without complications), 16 patients; and mild(More)
