A disease is a particular abnormal condition that adversely affects the structure or function of all or part of an organism and is not immediately due to any external injury. Diseases are often known to be medical conditions that are associated with specific signs and symptoms. A disease may be caused by external factors such as pathogens or by internal dysfunctions. For example, internal dysfunctions of the immune system can produce a variety of different diseases, including various forms of immunodeficiency, hypersensitivity, allergies, and autoimmune disorders.
The following outline is provided as an overview of and topical guide to health sciences:
Hepatitis is inflammation of the liver tissue. Some people or animals with hepatitis have no symptoms, whereas others develop yellow discoloration of the skin and whites of the eyes (jaundice), poor appetite, vomiting, tiredness, abdominal pain, and diarrhea. Hepatitis is acute if it resolves within six months, and chronic if it lasts longer than six months. Acute hepatitis can resolve on its own, progress to chronic hepatitis, or (rarely) result in acute liver failure. Chronic hepatitis may progress to scarring of the liver (cirrhosis), liver failure, and liver cancer.
The National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) is one of the institutes and centers that make up the National Institutes of Health, an agency of the United States Department of Health and Human Services (HHS).
Immunodeficiency, also known as immunocompromisation, is a state in which the immune system's ability to fight infectious diseases and cancer is compromised or entirely absent. Most cases are acquired ("secondary") due to extrinsic factors that affect the patient's immune system. Examples of these extrinsic factors include HIV infection and environmental factors, such as nutrition. Immunocompromisation may also be due to genetic diseases/flaws such as SCID.
Liver disease, or hepatic disease, is any of many diseases of the liver. If long-lasting it is termed chronic liver disease. Although the diseases differ in detail, liver diseases often have features in common.
Harrison's Principles of Internal Medicine is an American textbook of internal medicine. First published in 1950, it is in its 21st edition and comes in two volumes. Although it is aimed at all members of the medical profession, it is mainly used by internists and junior doctors in this field, as well as medical students. It is widely regarded as one of the most authoritative books on internal medicine and has been described as the "most recognized book in all of medicine."
Diseases of affluence, previously called diseases of rich people, is a term sometimes given to selected diseases and other health conditions which are commonly thought to be a result of increasing wealth in a society. Also referred to as the "Western disease" paradigm, these diseases are in contrast to "diseases of poverty", which largely result from and contribute to human impoverishment. These diseases of affluence have vastly increased in prevalence since the end of World War II.
Cryoglobulinemia is a medical condition in which the blood contains large amounts of pathological cold sensitive antibodies called cryoglobulins – proteins that become insoluble at reduced temperatures. This should be contrasted with cold agglutinins, which cause agglutination of red blood cells.
The Kolling Institute is located in the grounds of the Royal North Shore Hospital in St Leonards, Sydney Australia. The institute, founded in 1920, is the oldest medical research institute in New South Wales.
A non-communicable disease (NCD) is a disease that is not transmissible directly from one person to another. NCDs include Parkinson's disease, autoimmune diseases, strokes, heart diseases, cancers, diabetes, chronic kidney disease, osteoarthritis, osteoporosis, Alzheimer's disease, cataracts, and others. NCDs may be chronic or acute. Most are non-infectious, although there are some non-communicable infectious diseases, such as parasitic diseases in which the parasite's life cycle does not include direct host-to-host transmission.
The University of Sydney School of Medicine, also known as Sydney Medical School (SMS) is the graduate medical school of the University of Sydney. Established in 1856, it is the first medical school in Australia. In 2018, Sydney Medical School joined the newly formed Faculty of Medicine and Health at the University of Sydney. SMS is ranked 19th in the world and second in Australia in the 2021 QS Subject Rankings for medicine.
The Joondalup Family Health Study (JFHS) will be an extensively characterized, community-based cohort study, which will investigate the complex interplay of environmental, lifestyle and genetic components that affect the risk of common conditions such as asthma, heart disease and diabetes. The Study will take place in Joondalup, Western Australia and will have a strong focus on families and the health of both children and adults.
The following outline is provided as an overview of and topical guide to medicine:
An autoimmune disease is a condition that results from an anomalous response of the adaptive immune system, wherein it mistakenly targets and attacks healthy, functioning parts of the body as if they were foreign organisms. It is estimated that there are more than 80 recognized autoimmune diseases, with recent scientific evidence suggesting the existence of potentially more than 100 distinct conditions. Nearly any body part can be involved.
Cirrhosis, also known as liver cirrhosis or hepatic cirrhosis, and end-stage liver disease, is a condition of the liver in which the normal functioning tissue, or parenchyma, is replaced with scar tissue (fibrosis) and regenerative nodules as a result of chronic liver disease. Damage to the liver leads to repair of liver tissue and subsequent formation of scar tissue. Over time, scar tissue and nodules of regenerating hepatocytes can replace the parenchyma, causing increased resistance to blood flow in the liver's capillaries—the hepatic sinusoids—and consequently portal hypertension, as well as impairment in other aspects of liver function. The disease typically develops slowly over months or years.
The Translational Research Institute (TRI) is Australia's first translational medical research institute dedicated to translating scientific discoveries into applications for medical practice.
Tania Sorrell is an Australian infectious disease physician who is a Professor and Director of the Marie Bashir Institute for Infectious Diseases and Biosecurity at the University of Sydney. She serves as Chair of the National Health and Medical Research Council Research Translation Faculty Steering Group on New and Emerging Health Threats. She is interested in the diagnosis, prevention and treatment of infectious diseases.
Angela Webster is a clinical epidemiologist at the Sydney School of Public Health, University of Sydney, nephrologist and transplant physician at Westmead Hospital and director of Evidence Integration at the NHMRC Clinical Trials Centre, University of Sydney.
