Effect of training on the scope of oral and maxillofacial surgery.
The relationships between training and qualifications and the scope of oral and maxillofacial surgical practice was investigated by a survey of all full members of the Australian and New Zealand Association of Oral and Maxillofacial surgeons. It was found that scope did correlate to length of training. Three were differences in scope for more recently trained surgeons and by practice location. The possession of medical qualification did not necessarily affect scope of practice but did affect attitudes.

Airway occlusion pressure (P0.1)-a useful predictor for the weaning outcome in patients with acute respiratory failure-.
Twenty-five patients who required mechanical ventilatory support (MVS) after major surgery or severe burns were studied to determine whether airway occlusion pressure (P(0.1)) is a clinically useful indicator to predict the success or failure of the weaning trial. A total of 33 weaning trials were attempted on these patients. Of the 33 trials, 24 were followed by successful weaning and 9 by failure. ⋯ The alveolar-arterial P(O)(2) gradient, with an F i(O)(2) of 1.0, in weaning success and failure showed no statistical difference. In contrast, all patients in the success group had a P(0.1) of less than 3.5 cmH(2)O and those in the failure group had a P(0.1) of greater than 3.5 cmH(2)O ( P < 0.001). We conclude that P(0.1) is a clinically superior indicator for discontinuing MVS in patients with acute respiratory failure.
