Mass spectrometry is an analytic technique with high specificity and a growing presence in laboratory medicine. Various types of mass spectrometers are being used in an increasing number of clinical laboratories around the world, and, as a result, significant improvements in assay performance are occurring rapidly in areas such as toxicology, endocrinology, and biochemical genetics. This review...

Severe acute respiratory syndrome (SARS) is a newly emerged infectious disease with a significant morbidity and mortality. The major clinical features include persistent fever, chills/rigor, myalgia, malaise, dry cough, headache, and dyspnoea. Older subjects may present without the typical febrile response. Common laboratory features include lymphopenia, thrombocytopenia, raised alanine transam...

Quantitative bacteriology has considerable influence on the care and management of surgical wounds. Heretofore, these techniques have been limited to measurements of aerobic bacteria. A technique is reported herein which permits quantitation of obligately anaerobic bacteria in tissue specimens. This technique is easily reproduced in any clinical laboratory and eliminates the need for expensive ...

The present article introduces a new technique for chairside provisional fixed partial dentures fabrication. The described direct technique is suitable for a fast and relatively easy fabrication of provisional single crowns or small bridges. It does not necessitate any preliminary laboratory stages (such as wax-up e.g.) but rather tends to adapt the teeth morphology of a selected model to the s...
