Betaherpesvirus assembly and egress: Recent advances illuminate the path.

The human betaherpesviruses, human cytomegalovirus (HCMV; species Human betaherpesvirus 5) and human herpesviruses 6A, 6B, and 7 (HHV-6A, -6B, and -7; species Human betaherpesviruses 6A, 6B, and 7) are highly prevalent and can cause severe disease in immune-compromised and immune-naive populations in well- and under-developed communities. Herpesvirus virion assembly is an intricate process that requires viral orchestration of host systems. In this review, we describe recent advances in some of the many cellular events relevant to assembly and egress of betaherpesvirus virions.

Creation, evaluation, and continuing assurance of excellence of the certified surgical specialist.

A position paper on the subject of certified surgical specialists was published in 1966 under the direction of Professor Charles Wells of Liverpool, England. President John Terblanche of the International Federation of Surgical Colleges brought together leaders in surgical education from four nations (Australia, Japan, South Africa, United States) to update current "state-of-the art" views.

Status of a health care quality review programme in South Africa.

This paper provides an overview of an accreditation programme for health care facilities in South Africa. It traces the origin of COHSASA (The Council for Health Service Accreditation of Southern Africa) which began as a pilot programme in 1992, to its current status as the only accreditation body in the country. There are brief descriptions of its structure, how it is governed, and how standards were developed and organized.
