Luigi Fontana, M.D., Ph.D. (born in Trento, Italy on April 22, 1969) is an internationally known human systems biologist and one of the world’s leaders in the field of nutrition and healthy longevity in humans.
 He is currently a Professor of Medicine and Nutritional Sciences at University of Brescia, Italy and at Washington University in St. Louis, USA, where he co-directs with John Holloszy (one of the top world experts in the field of exercise physiology and preventive medicine) the Longevity Research Program.
Sande was a professor of Internal Medicine from 1971–1980 at the University of Virginia, where he performed research in mice on bacterial meningitis therapies such as novel antibiotics and corticosteroids.
 Dr Sande was Chief of Medical Services at San Francisco General Hospital in 1981 when he recognized a pattern of gay men being admitted with the rare pneumocystis pneumonia.
 His efforts on behalf of these patients resulted in the formation of an AIDS ward at San Francisco General Hospital and later an AIDS outpatient clinic.
 Teaming with such experts as Julie Gerberding and Paul Volberding he helped to craft what became known as the "San Francisco model" of AIDS therapy, a comprehensive, rational approach to care that avoided the fear and paranoia surrounding the disease at that time.
 The model addressed a need for infection-control guidelines, clinical studies and research financing and became a template for AIDS centers nationwide.
 Sande helped found to the Gladstone Institute of Virology and Immunology, which performed trials on some of the first anti-retrovirals such as zidovudine.
 He also helped to found the Infectious Diseases Institute at the Makerere University College of Health Sciences in Kampala, Uganda a major center for HIV education and research in Africa.
 Sande was a professor of Medicine at University of California, San Francisco from 1980–1996, chairman of the department internal medicine at University of Utah from 1996–2005 and Professor of medicine at University of Washington from 2005 until his death and president of the Infectious Diseases Society of America from 1993–4.
 He was also the editor of two highly regarded medical references "The Medical Management of AIDS."
 and "The Sanford Guide to Antimicrobial Therapy".
 He also gave the always popular and well attended annual update in Infectious Diseases at the American College of Physicians annual meeting as well as the clinical case presentations at the Infectious Diseases Society of America annual meeting.
Acute medicine is that part of internal medicine concerned with the immediate and early specialist management of adult patients with a wide range of medical conditions who present in hospital as emergencies.
 It developed in the United Kingdom in the early 2000s as a dedicated field of medicine, together with the establishment of acute medical units in numerous hospitals.
 Acute medicine is distinct from the broader field of emergency medicine, which is concerned with the management of all people attending the emergency department, not just those with internal medicine diagnoses.
 The emergence of acute medicine has both similarities with and differences from hospital medicine in North America, reflecting health system differences.
Joshua T. Mendell, M.D., Ph.D., is an associate professor of pediatrics and molecular biology and genetics at the Johns Hopkins School of Medicine, where he is a faculty member of the McKusick-Nathans Institute of Genetic Medicine.
 Mendell is a Howard Hughes Medical Institute early career scientist and a preceptor for two Johns Hopkins graduate programs.
 His molecular biology research examines microRNA (miRNA) regulation and function, with particular emphasis on miRNAs and cancer.
International health, also called "geographic medicine" or "global health", is a field of health care, usually with a public health emphasis, dealing with health across regional or national boundaries.
 One subset of international medicine, travel medicine, prepares travelers with immunizations, prophylactic medications, preventive techniques such as bednets and residual pesticides, in-transit care, and post-travel care for exotic illnesses.
 International health, however, more often refers to health personnel or organizations from one area or nation providing direct health care, or health sector development, in another area or nation.
 It is this sense of the term that is explained here.
 More recently, public health experts have become interested in global processes that impact on human health.
 Globalization and health, for example, illustrates the complex and changing sociological environment within which the determinants of health and disease express themselves.
Victor Almon McKusick (October 21, 1921 – July 22, 2008) was an American internist and medical geneticist, and Professor of Medicine at the Johns Hopkins Hospital, Baltimore.
 He was a proponent of the mapping of the human genome due to its use for studying congenital diseases.
 He is well known for his studies of the Amish and, what he called, "little people".
 He was the original author and, until his death, remained chief editor of Mendelian Inheritance in Man (MIM) and its online counterpart Online Mendelian Inheritance in Man (OMIM).
 He is widely known as the "father of medical genetics".
Frank H. Krusen (1898 - September 16, 1973) was an American physiatrist.
 He is regarded as a "founder" of the field of physical medicine and rehabilitation.
 He founded the first Department of Rehabilitation at Temple Hospital in 1928.
 Physiatrists remember his scholarly contributions, most notably through his numerous contributions to the medical literature on the use of therapeutic modalities in medicine, and his foundational textbook, Physical Medicine, published in 1941, and subsequently titled, Krusen’s Handbook of Physical Medicine and Rehabilitation (the 4th and last edition was published in 1990) 1].
 Dr. Krusen was the driving force behind the establishment of the first residency program in Physical Medicine at Mayo Clinic in 1936.
 He was also a charter member of the American Academy of Physical Medicine and Rehabilitation (AAPM&R) and served as its president from 1941-1942.
 His focused on the field on education, research, and collaboration with other colleagues in medicine and rehabilitation services, a framework for professional activities that remains relevant for PM&R in the 21st century.
Genetic Alliance is a nonprofit organization, founded in 1986 by Joan O. Weiss, working with Victor A. McKusick, to advocate for health benefits in the accelerating field of genomic research.
 This organization is a network of over 1,000 disease advocacy organizations, universities, government organizations, private companies, and public policy organizations.
 They aim to advance genetic research agendas toward health benefit by engaging a broad range of stakeholders, including healthcare providers, researchers, industry professionals, public policy leaders, as well as individuals, families and communities.
 They create programs using a collaborative approach, and aim to increase efficiency and reduce obstacles in genetic research, while ensuring that voices from the involved disease communities are heard.
 They also promote public policies to advance healthcare.
 Genetic Alliance provides technical support and informational resources to guide disease-specific advocacy organizations in being their own research advocates.
 They also maintain a biobank as a central storage facility for several organizations who otherwise would not have the infrastructure to maintain their own repository.
The Appalachian Center for Wilderness Medicine (ACWM) is a non-profit organization dedicated to promoting wilderness medicine in the southern Appalachian region of the United States of America.
 Dr. Seth C. Hawkins, an emergency physician who specializes in EMS and wilderness medicine, founded ACWM in 2007 in the state of North Carolina.
 It is the first regional wilderness medicine non-profit of its kind in the United States.
 Contemporary authorities in wilderness medicine have noted its importance in establishing a mechanism for regionally pooling information and resources in a field that otherwise has little connection between local or regional experts.
 Critical to that effort have been uses of the internet in ways not previously seen in wilderness medicine.
Peter H Beighton {'1': ", '2': ", '3': ", '4': "} (born 1934) is a South African a medical geneticist.
 Born in Lancashire in England in 1934 and qualified in medicine in 1957 at St Mary's Hospital, University of London.
 After several internships, Beighton served as a Medical Officer in the Parachute Regiment and with the United Nations forces during the Congo Crisis.
 In 1966 Beighton began training in internal medicine at St Thomas' Hospital in London and held a Fulbright research fellowship in clinical genetics in 1968-69 with Dr. Victor McKusick at Johns Hopkins Hospital in Baltimore, USA.
