Clinical classification and terminology: some history and current observations.
(9/451)
The evolution of health terminology has undergone glacial transition over time, although this pace has quickened recently. After a long history of near neglect, unimaginative structure, and factitious development, health terminologies are in an era of unprecedented importance, sophistication, and collaboration. The major highlights of this history are reviewed, together with important intellectual advances in health terminology development. The inescapable conclusion is that we are amidst a major revolution in the role and capabilities of health terminologies, entering an age of large-scale systems for health concept representation with international implications.

Food of the gods: cure for humanity? A cultural history of the medicinal and ritual use of chocolate.
(10/451)
The medicinal use of cacao, or chocolate, both as a primary remedy and as a vehicle to deliver other medicines, originated in the New World and diffused to Europe in the mid 1500s. These practices originated among the Olmec, Maya and Mexica (Aztec). The word cacao is derived from Olmec and the subsequent Mayan languages (kakaw); the chocolate-related term cacahuatl is Nahuatl (Aztec language), derived from Olmec/Mayan etymology. Early colonial era documents included instructions for the medicinal use of cacao. The Badianus Codex (1552) noted the use of cacao flowers to treat fatigue, whereas the Florentine Codex (1590) offered a prescription of cacao beans, maize and the herb tlacoxochitl (Calliandra anomala) to alleviate fever and panting of breath and to treat the faint of heart. Subsequent 16th to early 20th century manuscripts produced in Europe and New Spain revealed >100 medicinal uses for cacao/chocolate. Three consistent roles can be identified: 1) to treat emaciated patients to gain weight; 2) to stimulate nervous systems of apathetic, exhausted or feeble patients; and 3) to improve digestion and elimination where cacao/chocolate countered the effects of stagnant or weak stomachs, stimulated kidneys and improved bowel function. Additional medical complaints treated with chocolate/cacao have included anemia, poor appetite, mental fatigue, poor breast milk production, consumption/tuberculosis, fever, gout, kidney stones, reduced longevity and poor sexual appetite/low virility. Chocolate paste was a medium used to administer drugs and to counter the taste of bitter pharmacological additives. In addition to cacao beans, preparations of cacao bark, oil (cacao butter), leaves and flowers have been used to treat burns, bowel dysfunction, cuts and skin irritations. (+info)
Treatment of idiopathic clubfoot: an historical review.
(11/451)
Idiopathic clubfoot, one of the most common problems in pediatric orthopaedics, is characterized by a complex three-dimensional deformity of the foot. The treatment of clubfoot is controversial and continues to be one of the biggest challenges in pediatric orthopaedics. This controversy is due in part to the difficulty in measuring and evaluating the effectiveness of different treatment methods. We believe the heart of the debate is a lack of understanding of the functional anatomy of the deformity, the biological response of young connective tissue to injury and repair, and their combined effect on the long-term treatment outcomes. The aim of this review is not only to assess the different methods of clubfoot treatment used over the years in light of an evolving understanding of the pathoanatomy of the deformity, but to also clarify factors that allow a safe, logical approach to clubfoot management. Further research will be needed to fully understand the pathogenesis of clubfoot, as well as the long-term results and quality of life for the treated foot. (+info)
Molecular identification by "suicide PCR" of Yersinia pestis as the agent of medieval black death.
(12/451)
Medieval Black Death is believed to have killed up to one-third of the Western European population during the 14th century. It was identified as plague at this time, but recently the causative organism was debated because no definitive evidence has been obtained to confirm the role of Yersinia pestis as the agent of plague. We obtained the teeth of a child and two adults from a 14th century grave in France, disrupted them to obtain the pulp, and applied the new "suicide PCR" protocol in which the primers are used only once. There were no positive controls: Neither Yersinia nor Yersinia DNA were introduced in the laboratory. A negative result is followed by a new test using other primers; a positive result is followed by sequencing. The second and third primer pair used, coding for a part of the pla gene, generated amplicons whose sequence confirmed that it was Y. pestis in 1 tooth from the child and 19/19 teeth from the adults. Negative controls were negative. Attempts to detect the putative alternative etiologic agents Bacillus anthracis and Rickettsia prowazekii failed. Suicide PCR avoids any risk of contamination as it uses a single-shot primer-its specificity is absolute. We believe that we can end the controversy: Medieval Black Death was plague. (+info)
Richter's hernia and Sir Frederick Treves: an original clinical experience, review, and historical overview.
(13/451)
OBJECTIVE: To describe the clinical recognition, pathology, and management of Richter's hernia and to review the relevant literature of the past 400 years. SUMMARY BACKGROUND DATA: The earliest known reported case of Richter's hernia occurred in 1598 and was described by Fabricius Hildanus. The first scientific description of this particular hernia was given by August Gottlob Richter in 1778, who presented it as "the small rupture." In 1887, Sir Frederick Treves gave an excellent overview on the topic and proposed the title "Richter's hernia." To his work-a cornerstone to modern understanding-hardly any new aspects can be added today. Since then, only occasional case reports or small series of retrospectively collected Richter's hernias have been published. METHODS: The authors draw on their experience with 18 prospectively collected cases treated in the ICRC Lopiding Hospital for War Surgery in northern Kenya between February and December 1998 and review the relevant literature of the past 400 years. RESULTS: The classic features of Richter's hernia were confirmed in all case studies of patients: only part of the circumference of the bowel is entrapped and strangulated in the hernial orifice. The involved segment may rapidly pass into gangrene, yet signs of intestinal obstruction are often absent. The death rate in the authors' collective was 17%. CONCLUSION: Richter's hernia is a deceptive entity whose high death rate can be reduced by accurate diagnosis and early surgery. Considering the increasing incidence at laparoscope insertion sites, awareness of this special type of hernia with its misleading clinical appearance is important and of general interest. (+info)
Advocacy and community: the social roles of physicians in the last 1000 years. Part II.
(14/451)
Medicine in the 16th through the 18th centuries underwent profound changes -- from its understanding of the human body to its growing significance in the body politic. Key to advances in medicine as well as to the growth of nations was a conceptual shift in the perception of the natural world, which would ultimately provide a methodology for therapeutic advances as well as for the building of wealthy, strong nations.

Advocacy and community: the social roles of physicians in the last 1000 years. Part I.
(15/451)
Over the last 1000 years, the practice of medicine in the Western world has been shaped by extraordinary transformations -- in the organizational structures of healthcare delivery, the changing concepts of disease and illness, and the ethical and social issues posed to a growing and diversified profession. Some critical aspects that characterize contemporary Western medicine -- as professionally defined, highly organized and regulated, and scientifically and technologically based -- have emerged only within the last 200 years. For most of its history, medicine was practiced without these distinctions -- but precursors to many current tensions can be traced back to Hippocratic times. In the last millennium, medicine developed in tandem with emerging political ideologies and social structures, and the roles of physicians evolved to respond to the needs of individual patients, the profession, and society at large. As medicine became increasingly effective, it was harnessed into the political objectives of promoting social cohesion and productivity. Professional regulation and social mechanisms for the equitable distribution of healthcare became significant considerations for the profession and society. In this brief 3-part history, we will trace the major organizational, conceptual, and political changes that, together, by the year 2000, created a profession with responsibilities of advocacy for individual patients in concert with attention to the needs and demands of all the individuals in the larger community.

The Chinese Nail Murders: forensic medicine in Imperial China.
(16/451)
Robert van Gulik was a respected Dutch sinologist and author who first translated a collection of traditional Chinese detective stories into English and then created additional fictional stories based on the same characters and setting in the Tang dynasty. One of these stories, The Chinese Nail Murders, draws on van Gulik's professional interest in law and his knowledge of early Chinese works on forensic medicine. This novel develops a common theme in Chinese detective fiction, murder by a nail wound to the head. The difficulty in detection of this mode of violence posed a particular problem for the examining magistrate because postmortem examination was mostly limited to external observations. This essay compares the development of Chinese and Western forensic medicine in the context of the nail murder motif. (+info)
