Naturopathic and Western herbal medicine practice in Australia - a workforce survey

Background: Despite substantial growth in the use of complementary medicine, no comprehensive national study has been undertaken of the naturopathic and Western herbal medicine component of the healthcare workforce in Australia. This study aimed to examine the nature of these practices and this currently unregulated workforce in Australia. Methods: A comprehensive survey questionnaire was developed in consultation with the profession and distributed nationally to all members of the naturopathic and Western herbal medicine workforce. Results: The practices of herbal medicine and naturopathy make up a sizeable component of the Australian healthcare sector, with approximately 1.9 million consultations annually and an estimated turnover of $AUD 85 million in consultations (excluding the cost of medicines). A large proportion of patients are referred to practitioners by word of mouth. Up to one third of practitioners work in multidisciplinary clinics with other registered sectors of the healthcare community. The number of adverse events associated with herbal medicines, nutritional substances and homoeopathic medicines recorded in Australia is substantial and the types of events reported are not trivial. Data suggest that practitioners will experience one adverse event every 11 months of full-time practice, with 2.3 adverse events for every 1000 consultations (excluding mild gastrointestinal effects). Conclusion: These data confirm the considerable degree of utilisation of naturopathic and Western herbal medicine practitioners by the Australian public. However, there is a need to examine whether statutory regulation of practitioners of naturopathy and Western herbal medicine is required to better protect the public. (C) 2004 Elsevier Ltd.

Ultrasound organometry: the importance of body height adjusted normal ranges in assessing liver and spleen parameters among Chinese subjects with Schistosoma japonicum infection

Hepatosplenic measurements among 550 Chinese subjects, aged 3-59 years from Yueyang city-a nonendemic area for schistosomiasis in Hunan province, China-were performed to define normal ranges of ultrasound organometry for assessing hepatosplenic, morbidity in Schistosoma japonicum infection. Measurements included the size of the liver (left lobe and right lobe), the main portal vein stem, the peripheral periportal vein branches, and spleen length and thickness. The results document the significant relationship between body height and organometric parameters. The reference values stratified by body height improve the accuracy of assessment. Thus, height-based normal ranges established in this study can be applied in hospital routine and in field studies of patients infected with S. japonicum in Hunan province and in other endemic areas of China.
