These standards A are recommended for anesthesia professionals throughout the world. They are intended to provide guidance and assistance to anesthesia professionals, their professional societies, hospital and facility administrators, and governments for improving and maintaining the quality and safety of anesthesia care. They were adopted by the World Federation of Societies of Anaesthesiologists on the 13 th June 1992, and revisions were ratified on 5 th March 2008 and on 19 th March 2010. For some anesthesia services, groups, and departments these standards will represent a future goal, while for others they may already have been implemented and be regarded as mandatory. It is recognized that in some settings facing challenges in resources and organization, not even those standards regarded as mandatory are met at present. The provision of anesthesia under such circumstances should be restricted to procedures which are absolutely essential for the urgent or emergency saving of life or limb, and every effort should be made by those responsible for the provision of healthcare in these areas and settings to ensure that the standards are met. Provision of anesthesia care at standards lower than those outlined as mandatory for anesthesia for elective surgical procedures simply cannot be construed as safe acceptable practice. The most important standards relate to individual anesthesia professionals. Monitoring devices play an important part in safe anesthesia as extensions of human senses and clinical skills rather than their replacement. Adopting the standardized language of the World Health Organization, minimum standards that would be expected in all anesthesia care for elective surgical procedures are This article is reproduced with permission from the World Federation of Societies of Anaesthesiologists (WFSA) and appeared previously on the WFSA website (http://www.anaesthesiologists.org/).

Neuroendocrine tumors are more common in the female than male genital tract; most are uterine small cell carcinomas or ovarian carcinoids. Primary ovarian carcinoids are divided into insular, trabecular, strumal, and mucinous types; most are benign. Carcinoids metastatic to the ovary are more aggressive; most arise in the gastrointestinal tract. Scattered neuroendocrine cells are seen in a variety of ovarian surface epithelial tumors; sporadic mucinous cystic tumors with neuroendocrine cells have been associated with Zollinger-Ellison syndrome. Frank neuroendocrine carcinomas in the ovary include small cell carcinoma and large cell neuroendocrine carcinoma, each with a poor prognosis and often associated with a conventional surface epithelial tumor Such carcinomas also occur in the endometrium and cervix. Uterine carcinoids are rare if strict criteria are applied. Small cell neuroendocrine carcinomas also occur rarely in the vagina and vulva. Most male genital tract neuroendocrine tumors are prostatic small cell carcinomas or testicular carcinoids. Extragonadal carcinoids of the male genital tract are rare. Testicular carcinoids should be distinguishedfrom metastatic tumors. It is important to distinguish prostatic small cell carcinoma from poorly differentiated adenocarcinoma with small cells. Small cell neuroendocrine carcinomas also occur rarely in the scrotum, penis, and penile urethra.

As part of a major patient safety/risk management effort, the Department of Anaesthesia of Harvard Medical School, Boston, has devised specific, detailed, mandatory standards for minimal patient monitoring during anesthesia at its nine component teaching hospitals. Such standards have not previously existed, and resistance to the concept was anticipated but not seen. The standards are technically achievable in all settings and affordable in terms of effort and cost. Early detection of untoward trends or events during anesthesia will result in prevention or mitigation of patient injury; this, in turn, may also help counter the explosive increases in anesthesia-related malpractice actions, settlements, judgments, and insurance premiums. The committee process used is applicable to the promulgation of standards of practice for all medical specialties and any organized group of medical practitioners.
