Following isolation of Legionella pneumophila from a special dental station water circuit, used primarily to cool high-speed dental drills which produce fine aerosols, a case finding and environmental survey was undertaken. Widespread colonization of the dental stations was found and the results suggested that amplification of the background levels of L.(More)
The metabolism and renal effects of isoflurane sedation were studied for 24 h in patients undergoing mechanical ventilation. Forty-six patients admitted to our intensive therapy unit were allocated randomly to receive either 0.1-0.6% isoflurane or midazolam 0.01-0.2 mg kg-1 h-1 for sedation. In 26 patients sedated with isoflurane, plasma inorganic fluoride(More)
For the purpose of rapid measurement, the performance of a differential cell, consisting of a combination pH electrode and a F- electrode and used at low pH (1.2), was compared with the use of a single F- electrode at pH 5.0. The differential cell proved to be as accurate and consistent as the single electrode: its response time was 2 min for a saliva(More)
This study focuses on women's primary patterns of abuse for selected drugs (heroin, marijuana, barbiturates, amphetamines, sedatives, and tranquilizers) at treatment admission in relation to age at first use, marital status, education status, and race. The sample consisted of 51 390 women admitted to treatment during a recent 12 month period. The results(More)
In-vitro fluoride uptake by mid-coronal, premolar enamel surfaces from topically-applied solutions of NH4HF2 was determined using a multi-electrode system for fluoride and calcium analyses. In tooth surfaces dehydrated with 100 per cent ethanol before the topical application of 1 per cent aqueous NH4HF2, there was a 2-3-fold increase in fluoride(More)
