This article reviews the key issues arising in the revision of the International Classification of Impairments, Disabilities, and Handicaps (ICIDH) from a mental health perspective, and describes the work of the Disability Working Group of the WHO's Division of Mental Health. The ICIDH, which describes the consequences of disorders at three levels as impairments, disabilities, and handicaps, is generally applicable and useful for mental health purposes. While some impairments are mainly a consequence of 'mental' disorders (e.g. cognitive impairment), there should be no differences between mental and physical disorders in the classification scheme, to avoid a dichotomy between mind and body. There is also a need to improve the ways in which interference with the performance of social roles is described, since this is often the most obvious consequence of mental disorders. This article presents the potentials of the ICIDH in the field of mental health, and gives recommendations for the development of the revision process of the ICIDH. To stimulate the process of producing a 'common language' in the ICIDH related to mental health issues, former and potential users of the ICIDH are invited to give comments and suggestions.

Snails and snail farming: an introduction for the veterinary profession.

In the past veterinary interest in snails has been confined to their role in the transmission of disease; nowadays the trend to keep these animals in captivity--for food, for study, as 'companion animals'--means that the profession is increasingly likely to be consulted about their health, welfare or conservation. An understanding of the biology of snails is an important prerequisite to work with them. Land snails are hermaphrodite and have a complex reproductive system; other organs also show special adaptations. Management methods vary considerably and farmed snails can be maintained under extensive or intensive conditions. Methods for handling and transporting them are important considerations. There is little published information on the diseases and pathology of snails but suboptimum environment, poisons, nutritional deficiencies, predators and parasites are known to cause, or contribute, to their mortality.

Restraint and anaesthesia of primates.

The methods available for the restraint and anaesthesia of captive primates are discussed, emphasising the differences between the techniques for primates and those for other mammals; the importance of humane methods of physical restraint is emphasised. The agents available for chemical restraint and surgical anaesthesia are considered in terms of their ease of administration, the dose rate required, speed of induction and recovery, analgesic properties, muscle relaxation and side effects. New agents are available which are potentially useful in primates.
