BACKGROUND Techniques for sampling arterialised capillary blood from the finger pulp and the earlobe were first described over two decades ago but, although close agreement between arterial values and earlobe samples has been demonstrated in normal subjects, this technique is not in common usage. METHODS Forty patients with chronic lung disease and a wide(More)
Abnormalities of blood glucose are common in patients undergoing surgery, and in recent years there has been considerable interest in tight control of glucose in the perioperative period. Implementation of any regime of close glycemic control requires more frequent measurement of blood glucose, a function for which small, inexpensive, and rapidly responding(More)
Accurate monitoring of glucose in the perioperative environment has become increasingly important over the last few years. Because of increased cost, turnaround time, and sample volume, the use of central laboratory devices for glucose measurement has been somewhat supplanted by point-of-care (POC) glucose devices. The trade-off in moving to these POC(More)
Six patients with pre-existing rheumatic joint disease presented with overwhelming septicaemia but without overt signs of joint inflammation. Joint aspirates demonstrated multifocal staphylococcal infective arthritis. Despite intensive care all six died from the infection or its immediate sequelae. The contrast between this clinical entity and classical(More)
The purpose of an ontology is to structurally define knowledge about a topic. For the practice of simulation, ontologies have been demonstrated to be useful across a variety of techniques ranging from formally defining the components of dynamic models and capturing key simulation domain constraints to interrelating dynamic model components and geometry in(More)
As the human immunodeficiency virus (HIV) epidemic continues, there are increasing numbers of patients with HIV-related disease. Those doctors studying for the MRCP exam will need to be familiar with the common manifestations of HIV infection and acquired immunodeficiency syndrome.
