A comparative study of ten (10) products recommended for disinfection and/or sterilization of dental instruments is detailed. Four (4) out of fourteen (14) characteristics have been evaluated, namely corrosive power, monthly cost, odor and availability.
The nutrient intake of 20 independent and 18 dependent elderly persons is assessed in nursing home long-stay wards of a Melbourne geriatric teaching hospital. An assessment of the specific nutrient densities of the diet and comparison with recommended nutrient densities indicates that, not only is nutrient intake compromised because of low intakes of food energy, but also the quality of the diet is unsatisfactory. In institutional studies, those aged persons receiving supervision at meal times consume a more adequate diet than those able to feed themselves.

One hundred and seventy five Vietnamese adults with severe and complicated malaria admitted to a rural district hospital were entered into an open randomized comparative study to compare 4 treatment regimens based on artemisinin and its derivatives. The median time of defervescence was 48 h (95% confident interval [CI] 38-58 h) in those given intramuscular (i.m.) artemether, 42 h (95% CI 36-48 h) in those given artemisinin suppositories, 36 h (95% CI 30-42 h) in those receiving artesunate (i.m.) and 30 h (95% CI 18-42 h) in those receiving intravenous artesunate (P = 0.13). The respective median parasite clearance times were 30 h (95% CI 26-34 h), 30 h (95% CI 24-36 h), 24 h (95% CI 15-33 h), and 24 h (95% CI 15-33 h) (P = 0.30); the median times for recovery of consciousness were 47 h (95% CI 31-63 h), 24 h (95% CI 18-30 h), 30 h (95% CI 18-42 h), and 24 h (95% CI 4-44 h) (P = 0.18); and the mortality rates were 11.1%, 17.6%, 10.2% and 16.6%, respectively (P = 0.64). There was no significant difference in efficacy between the 4 treatments.
