Comparing the incidence of lower extremity amputations across the world: the Global Lower Extremity Amputation Study.

A substantial proportion of lower extremity amputations (LEAs), particularly in people with diabetes, are thought to be preventable by the provision of appropriate health care. Information on the incidence of LEAs which is accurate, up-to-date, and comparable cross-sectionally and longitudinally is essential to guide and monitor interventions aimed at their prevention. Current information on the incidence of LEAs is limited and differences between studies in case definition, presentation of rates, level of ascertainment, and population age structure often make meaningful comparisons impossible. To remedy this situation the global LEA study has been established. The study is designed to compare the incidence of LEAs over time within and between communities across the world. The methodology includes adherence to a standard definition of LEA, standardized methods of data collection with built-in quality control, and correction for under-ascertainment of cases (using capture-recapture methodology). Centres wishing to take part in the study must be able to identify a study population of at least 250,000, have reasonably up-to-date population numbers by age and sex, and be prepared to stay in the study for at least 2 years. A study registration form (Appendix 1) is provided.

Self-amputation of the ear: three men amputate four ears within five months.

Four instances are presented of self-amputation of the pinna of the external ear carried out by three right-handed, white males between January 1993 and May 1993. The common characteristics of these subjects--two men with personality disorder and one with schizophrenia--are discussed and compared with other examples of self-mutilation involving the face and ears, including that of van Gogh. A survey of Australian and New Zealand prisons was conducted to determine the frequency of this form of self-mutilation within the last five years, and yielded only one other case. Connections exist between the amputees supporting the notion that self-mutilation is "contagious"; the relevance of this to issues of management is considered.
