AimTo compare the rate of heat flow into two vacuum flasks with vacuum envelopes of different materials (glass and stainless steel).DesignProspective non‐randomised comparison (n= 2).SettingHome (edge of the Great Sandy Desert), Sunday.Outcome measureChange in liquid nitrogen content over time.ResultsWithin eight hours, the flask with a stainless steel envelope lost almost all its nitrogen (about 800 g), while the flask with a glass envelope lost only about 100 g. The stainless steel flask therefore had a heat leakage rate about eight times that of the glass flask.ConclusionA glass‐lined vacuum flask is better for keeping liquid nitrogen cold (and coffee hot) than a steel‐lined flask.

摘要:

ObjectiveTo determine the characteristics of a new cocoa‐based edible spacer device for the delivery of aerosol bronchodilator.DesignIn‐vitro comparison of two spacer devices (standard and edible) and determination of bronchodilator response using the edible spacer.SettingA university children's hospital in Western Australia.SubjectsTwo volunteers with moderate asthma.ResultsCompared with a standard spacer, the edible spacer delivered significantly more bronchodilator in droplets of a size likely to enter the respiratory tract. A significant bronchodilator response occurred in two out of two subjects when salbutamol was inhaled orally via the chocolate spacer. No significant bronchodilator response occurred in either subject when the spacer was eaten at the end of the study.ConclusionThe chocolate spacer used in this study is a suitable device to deliver salbutamol by inhalation. However, there may be potential drawbacks of weight gain in some patients and meltdown in hot climates.

摘要:

ObjectiveTo help medical students learn about Aboriginal culture and health by introducing them to Aboriginal people living in rural and remote areas.SettingA seven‐day field trip to Aboriginal communities and local health services in the eastern Goldfields Region of Western Australia.MethodsStudents interviewed local Aboriginal people, and representatives of community organisations and health service providers, and supplemented this information with their own field observations. The field research was used in completing three community health projects: one on infant health, another on environmental health, and a third on general beliefs of Aboriginal people about health and disease, prevention and treatment, and traditional and Western medicine.Main outcome measuresKnowledge about and attitudes towards Aboriginal people were assessed by anonymous questionnaires before and after the field trip.ResultsThe field trip tripled (on average) the number of Aboriginal people with whom the students had ever had a conversation. Potentially important increases were seen in the proportion of students who could correctly name actions of doctors that Aboriginal people might find offensive. Seven of the nine students “strongly agreed” that their attitudes to Aboriginal people were more positive as a result of the trip, and the other two “agreed”. All would recommend such a trip to their colleagues.ConclusionsBy visiting Aboriginal communities, medical students can gain important insights into Aboriginal health problems and ways in which health services can be made more acceptable to Aboriginal people.

摘要:

Sir Gustav Nossal reflects on the research prominence of the Walter and Eliza Hall Institute under his stewardship and says that the glittering prizes in research will go to those who combine teamwork and high technology in a bubbling cauldron of ideas.
