A total of 141 cases of strictly defined cerebral malaria were studied in a controlled trial of three regimens: (1) intramuscular artemether plus oral mefloquine, (2) intravenous artesunate plus oral mefloquine, and (3) intravenous quinine (with or without an initial loading dose) plus oral tetracycline. The overall mortalities in each group were 14%, 8.3% and 34.3% respectively. The average parasite clearance time was 27.30 +/- 19.62 hours in regimen 1, 41.84 +/- 17.55 hours in regimen 2, and 47.30 +/- 21.95 hours in regimen 3.

In Thailand Plasmodium falciparum malaria is highly resistant to available antimalarials. Investigations on the efficacy of existing antimalarials and of alternative drugs are urgently needed. Artesunate has been shown to be effective against falciparum malaria, but is associated with a high recrudescence rate. We have carried out a comparative clinical trial of the standard regimen of quinine + tetracycline versus oral artesunate at a 700-mg total dose given over 5 days to patients with acute uncomplicated falciparum malaria.

A randomized, controlled, malaria-clinic-based field trial was conducted to compare compliance with a 7-day quinine + tetracycline regimen and a 5-day 700-mg artesunate regimen for the treatment of uncomplicated falciparum malaria in a community in Thailand. Of 137 patients, aged 15-60 years attending a malaria clinic, 77 received artesunate and 60 received quinine + tetracycline. Compliance and cure rates were evaluated on days 5 (artesunate) and 7 (quinine + tetracycline) using patient interview/residual pill counts and peripheral blood smear, respectively.

A randomized, controlled, malaria-clinic-based field trial was carried out to compare the cost-effectiveness of a 5-day 700-mg oral artesunate and a 7-day quinine + tetracycline regimen for the treatment of uncomplicated falciparum malaria in Thailand. Cost-effectiveness was determined from the providers' perspective and based on curative effectiveness. A total of 137 patients, aged 15-60 years, attending a malaria clinic were followed for 28 days, 60 of them received quinine + tetracycline and 77 received artesunate.

The activities of primaquine in combination with quinine or artesunate against asexual- and sexual-stage parasites were assessed in 176 adult Thai patients with uncomplicated Plasmodium falciparum malaria. Patients were randomized to one of the six following 7-day oral treatment regimens: (i) quinine alone, (ii) quinine with tetracycline, (iii) quinine with primaquine at 15 mg/day, (iv) quinine with primaquine at 30 mg/day, (v) artesunate alone, or (vi) artesunate with primaquine. Clinical recovery occurred in all patients.

BACKGROUND: Increasing rates of failure of artemisinin-based combination therapy have highlighted the possibility of emerging artemisinin resistance along the Thai-Cambodian border. We used an integrated in vivo-in vitro approach to assess the presence of artemisinin resistance in western Cambodia. This article provides additional data from a clinical trial that has been published in The New England Journal of Medicine.

The phylum Apicomplexa comprises intracellular protozoa that include many human pathogens. Their nearest relatives are chromerids and colpodellids. We report a case of a Babesia spp.-like relapsing infection caused by a newly described microorganism related to the Apicomplexa. This case is highly suggestive of a previously undescribed type of colpodellid that infects vertebrates.

(3)H-tetracycline ((3)H-TC) is thought to be superior to calcium (Ca) isotopic tracers for estimating bone resorption rates due to the less redeposition upon release in animal models. However, these 2 tracers have not been compared directly using complete kinetic studies with sampling of blood, urine, feces, and bone. Our goal was to compare the 2 isotopes for evaluating bone turnover. We firstly developed a model for (3)H-TC kinetics in 4-mo-old female rats (n = 3) by measuring the tracer in serum, urine, and feces over 4 d.

Tetracyclines were developed as a result of the screening of soil samples for antibiotics. The first(t) of these compounds, chlortetracycline, was introduced in 1947. Tetracyclines were found to be highly effective against various pathogens including rickettsiae, as well as both gram-positive and gram-negative bacteria, thus becoming the first class of broad-spectrum antibiotics. Many other interesting properties, unrelated to their antibiotic activity, have been identified for tetracyclines which have led to widely divergent experimental and clinical uses.

Regarding treatment of acne vulgaris and rosacea, there is not much difference between hospital and practice nor among practicing dermatologists. Most of the assistants performing the important physical-manual treatment have had the same training. After analytical conversation and etiologic as well as diagnostic classification, the patients undergo the following manual treatment: cleansing, astringing, removing of comedones, massage, face pack, and covering with tinted emulsion.
