The safe use of syringe drivers for palliative care: an action research project.

A palliative care team in north Scotland identified serious drug errors occurring in the local health-care trust. These were connected with the use of variable rate syringe drivers (IVAC P100) to deliver pain and symptom management rather than the more suitable Graseby MS26. An action research approach was taken to effecting change. An educational workshop was set up which 23 nurses attended. Clinical support was provided and 3 months later an evaluation was carried out. Of the 13 nurses who had used an MS26, most were able to correctly follow the process of setting up the driver and had made appropriate observations, but drug calculations were a problem. Change was stated to have taken place in seven clinical areas but the degree of change was variable. Facilitators and obstacles to the change process are identified and recommendations made for the next round in the action research cycle.

Production of antibacterial compounds by phylloplane-inhabiting yeasts and yeastlike fungi.

The production of antibacterial compounds by yeasts and yeastlike fungi isolated from the phylloplane is reported. Aureobasidium pullulans, Citeromyces matritensis, Cryptococcus laurentii, Rhodotorula glutinis, and Sporobolomyces roseus produced antibacterial compounds inhibitory to both Pseudomonas fluorescens and Staphylococcus aureus in an overlay bioassay. In contrast, isolates of Candida albicans, Filobasidium uniguttulatum, Saccharomyces cerevisiae, Torulaspora delbruckii, Tremella foliacea, Trichosporon beigelii, and Trichosporon dulcitum obtained from soil or from culture collections did not produce inhibitory compounds when screened by the same procedure. The production of antibacterial compounds was examined in more detail, using several isolates of A. pullulans distinguished by cluster analysis on the basis of biochemical and physiological tests. They were found to produce a range of antibacterial compounds with different activities. Two distinct antibiotics were produced by an isolate of A. pullulans in liquid culture during both the logarithmic and the stationary phases of growth.

Cholinergic supersensitivity of the iris in primary open angle glaucoma. A clinical study.

Twenty patients with untreated primary open angle glaucoma (POAG) were tested for the presence of cholinergic supersensitivity of the iris using a 0.1% solution of pilocarpine. Nineteen patients had a significant miotic response compared to six of a group of twenty control subjects. We believe that an ocular parasympathetic neuropathy may be an important factor in promoting or perpetuating elevated intra ocular pressure in POAG. The mechanism of this is suggested and several possible areas of further study discussed.
