Consensus regarding the use of thrombolysis to treat acute pulmonary embolism has not yet been reached. There is good evidence that thrombolytic agents dissolve clot more rapidly than heparin. ⋯ One evolving position is that, in addition to patients presenting in circulatory collapse, for whom thrombolysis has been demonstrated to be life-saving, a subgroup of patients may be identified by echocardiography, through its ability to assess right ventricular dysfunction, who should also be considered for thrombolytic therapy. It remains to be seen whether this approach can reduce the death rate associated with pulmonary embolism.

Uncontrolled intracranial hypertension after traumatic brain injury (TBI) contributes significantly to the death rate and to poor functional outcome. There is no evidence that intracranial pressure (ICP) monitoring alters the outcome of TBI. The objective of this study was to test the hypothesis that insertion of ICP monitors in patients who have TBI is not associated with a decrease in the death rate. ⋯ ICP monitor insertion rates vary widely in Ontario's trauma hospitals. The insertion of an ICP monitor is associated with a statistically significant decrease in death rate among patients with severe TBI. This finding strongly supports the need for a prospective randomized trial of management protocols, including ICP monitoring, in patients with severe TBI.

To examine the suitability of a plaster-fibreglass hybrid cast for orthopedic applications, comparing them to plaster of Paris (POP) and fibreglass constructs. ⋯ Plaster-fibreglass hybrid casts should be considered for orthopedic use on the basis of their strength, stiffness, weight and cost, combined with their acknowledged advantages of good moulding ability and water resistance.
