Can telepharmacy provide pharmacy services in the bush?

Rural and remote community pharmacies service large areas of rural Queensland, and because of the distances involved often do not meet the patients for whom they provide medication. Telepharmacy would improve the quality of pharmaceutical services provided in rural and remote areas, by allowing community pharmacists to have realtime contact with dispensing doctors, aboriginal health workers and patients via a video-phone. We used commercial (analogue) videophones to connect community pharmacists to dispensing doctors, patients in depot pharmacies (i.e. those with no pharmacist) and aboriginal health workers. However, various problems occurred and only 10 video-phone interactions were recorded during the six-month project. In all of the recorded interactions, the video-phone was actually used as a conventional telephone because a video-connection could not be established at the time of the call. (This may have been due to telephone network problems in the rural areas.) Despite these problems, all project participants showed great enthusiasm for the potential benefits of such a service.

Prescription drug samples: Does this marketing strategy counteract policies for quality use of medicines?

Prescription drug samples, as used by the pharmaceutical industry to market their products, are of current interest because of their influence on prescribing, and their potential impact on consumer safety. Very little research has been conducted into the use and misuse of prescription drug samples, and the influence of samples on health policies designed to improve the rational use of medicines. This is a topical issue in the prescription drug debate, with increasing costs and increasing concerns about optimizing use of medicines. This manuscript critically evaluates the research that has been conducted to date about prescription drug samples, discusses the issues raised in the context of traditional marketing theory, and suggests possible alternatives for the future.

Elevated plasma levels of human urotensin-II immunoreactivity in congestive heart failure

Human urotensin-II (hU-II) is the most potent endogenous cardiostimulant identified to date. We therefore determined whether hU-II has a possible pathological role by investigating its levels in patients with congestive heart failure (CHF). Blood samples were obtained from the aortic root, femoral artery, femoral vein, and pulmonary artery from CHF patients undergoing cardiac catheterization and the aortic root from patients undergoing investigative angiography for chest pain who were not in heart failure. Immunoreactive hU-II (hU-II-ir) levels were determined with radioimmunoassay. hU-II-ir was elevated in the aortic root of CHF patients (230.9 +/- 68.7 pg/ml, n = 21; P < 0.001) vs. patients with nonfailing hearts (22.7 +/- 6.1 pg/ml, n = 18). This increase was attributed to cardiopulmonary production of hU-II-ir because levels were lower in the pulmonary artery (38.2 +/- 6.1 pg/ml, n = 21; P < 0.001) than in the aortic root. hU-II-ir was elevated in the aortic root of CHF patients with nonischemic cardiomyopathy (142.1 +/- 51.5 pg/ml, n = 10; P < 0.05) vs. patients with nonfailing hearts without coronary artery disease (27.3 +/- 12.4 pg/ml, n = 7) and CHF patients with ischemic cardiomyopathy (311.6 +/- 120.4 pg/ml, n = 11; P < 0.001) vs. patients with nonfailing hearts and coronary artery disease (19.8 +/- 6.6 pg/ml, n = 11). hU-II-ir was significantly higher in the aortic root than in the pulmonary artery and femoral vein, with a nonsignificant trend for higher levels in the aortic root than in the femoral artery. The findings indicated that hU-II-ir is elevated in the aortic root of CHF patients and that hU-II-ir is cleared at least in part from the microcirculation.
