TL;DR: As breakthroughs of malaria occurred at the earliest after seven weeks self treatment should not be recommended for travellers staying only a short time, but the combination of chloroquine phosphate with proguanil hydrochloride is recommended because it results in fewer side effects.
Abstract: As malaria caused by Plasmodium falciparum has become resistant to chloroquine alternative drug regimens need to be developed. The prophylactic efficacy against malaria and the side effects of chloroquine phosphate 500 mg weekly with proguanil hydrochloride 200 mg daily was compared with the efficacy of chloroquine 500 mg weekly with sulfadoxine 500 mg-pyrimethamine 25 mg weekly in a randomised study of Scandinavian travellers to Kenya and Tanzania during 1984-5. A total of 767 subjects (416 male and 351 female; 384 taking chloroquine phosphate with proguanil hydrochloride and 383 taking chloroquine with sulfadoxine-pyrimethamine) completed a diary on the breakthrough of malaria and the side effects of treatment while taking the drugs. They were also asked to make thick blood films when symptoms like those of malaria occurred, which were sent to and analysed in Denmark. Four subjects taking chloroquine with proguanil hydrochloride and three taking chloroquine with sulfadoxine-pyrimethamine developed falciparum malaria, which was verified microscopically. Side effects were reported by 36 subjects taking chloroquine phosphate with proguanil hydrochloride and 55 taking the other regimen (p = 0.043). The side effects of both regimens were generally mild, but the combination of chloroquine phosphate with proguanil hydrochloride is recommended because it results in fewer side effects. As breakthroughs of malaria occurred at the earliest after seven weeks self treatment should not be recommended for travellers staying only a short time. Thick blood films are useful for diagnosis of suspected cases of malaria, can be prepared by non-specialists in Africa, and can be analysed successfully after long delays.

TL;DR: Although encouragement to condom use is prudent in an epidemiological scale, truly safe sex with an HIV-positive partner using condoms is a dangerous illusion.
Abstract: 30 female prostitutes and 16 persons from the hospital staff each tested 10 latex condoms by vaginal intercourse. Six dropped out. Condom rupture occurred at least once for 7/40 persons (95% confidence interval 7–33%). Total condom rupture rate was 5%. Although encouragement to condom use is prudent in an epidemiological scale, truly safe sex with an HIV-positive partner using condoms is a dangerous illusion.

TL;DR: A schedule with regular microbiologic and parasitic examinations and few antibody tests, but with more antigen tests is suggested, to examine the therapeutic consequences of diagnostic tests for AIDS-related infections.
Abstract: To examine the therapeutic consequences of diagnostic tests for AIDS-related infections, case records from 33 deceased AIDS patients were reviewed; 23 were autopsied. Determination of serum antibody titres was not important. In particular, there was no relation between titres and isolation of cytomegalovirus (CMV); isolation attempts or possibly antigen determination would be better. Samples for CMV isolation were obtained from 31 patients; only 7 were negative. Blood, faeces, and particularly sputum cultures gave a low yield; the number of such examinations could be reduced considerably. However, 4/7 disseminated infections with atypical mycobacteria were only revealed at autopsy, despite numerous cultures in vivo. Liver biopsies were not helpful. Diagnostic procedures for Pneumocystis carinii pneumonia by lung biopsy caused pneumothorax in 3/15 patients; bronchoalveolar lavage or treatment/prophylaxis without diagnosis could be considered. In 8 autopsies, microscopy was suggestive of cerebral toxoplasmosis, but only 1 patient had presented important clinical symptoms. We suggest a schedule with regular microbiologic and parasitic examinations and few antibody tests, but with more antigen tests.
