| classical epidemiology | <epidemiology> Our term for the varieties of epidemiology primarily concerned with the statistical relationships between disease agents, both infectious and non-infectious; for example a study to establish the relative risk of lung cancer associated with smoking. We contrast this with ecological epidemiology. (05 Dec 1998) |
|---|---|
| clinical epidemiology | The field concerned with applying epidemiological principles in a clinical setting.Whereas classical epidemiology studies populations in an attempt to assess causes and distribution of disease and to formulate statistical measures of risk, clinical epidemiology focuses on medically defined populations (patients). (05 Mar 2000) |
| ecological epidemiology | <epidemiology> A branch of epidemiology which views disease as a result of the ecological interactions between populations of hosts and parasites; what we do. We contrast this with classical epidemiology. (05 Dec 1998) |
| epidemiology | <study> The study of the distribution and determinants of health-related states and events in populations and the control of health problems, the study of epidemic disease. (27 Sep 1997) |
| epidemiology, classical | The study of populations in order to determine the frequency and distribution of disease and measure risks. (12 Dec 1998) |
| epidemiology, clinical | Epidemiology focused specifically upon patients. (12 Dec 1998) |
| epidemiology, molecular | The application of molecular biology to the answering of epidemiological questions. The examination of patterns of changes in DNA to implicate particular carcinogens and the use of molecular markers to predict which individuals are at highest risk for a disease are common examples. (12 Dec 1998) |
| agonal infection | An acute infection, commonly pneumonic or septic, occurring toward the end of any disease and often the cause of death. Synonym: agonal infection. (05 Mar 2000) |
| airborne infection | A mechanism of transmission of an infectious agent by particles, dust, or droplet nuclei suspended in the air. (05 Mar 2000) |
| apical infection | Implantation of microorganisms at the apex of a tooth, usually the result of the migration of microorganisms from the pulp canal through the apical foramen. (05 Mar 2000) |
| arbovirus infection | <virology> A type of viral infection that is transmitted by mosquitoes in late spring to early autumn. One manifestation is encephalitis (central nervous system infection). (27 Sep 1997) |
| ascariasis infection | <microbiology> Infection by the nematode Ascaris lumbricoides and is characterised by an early pulmonary phase related to larval migration and a later, prolonged intestinal phase. Adult worms are 15-40 cm in length and maintain themselves in the lumen of the small intestine. Infection occurs after ingesting eggs contained in contaminated food or more commonly, by transmission to the mouth by the hands after contact with contaminated soil. Treatment is with mebendazole or pyrantel pamoate. (27 Sep 1997) |
| atypical mycobacterial infection | <microbiology> Infection with organisms from the Mycobacterium genus other than tuberculosis. Risk factors include immunocompromised patients and those with AIDS. Mycobacterium avium intracellulare is an example which frequently infects AIDS patients. Atypical mycobacterial infections can cause abscesses, septic arthritis and osteomyelitis. Treatment can be difficult due to the emergence of resistance to standard antitubercular antibiotics. (27 Sep 1997) |
| bacterial infection | <microbiology> Bacteria are group of micro-organisms that are a single cell approximately 1 micron in transverse diameter. Some bacteria cause disease in man, requiring treatment with an antibiotic. (27 Sep 1997) |
| bladder infection | Some people are at more risk for bladder and other urinary tract infections (UTIs) than others. One woman in five develops a UTI during her lifetime. Not everyone with a UTI has symptoms. Common symptoms include a frequent urge to urinate and a painful, burning when urinating. Underlying conditions that impair the normal urinary flow can lead to more complicated UTIs. (12 Dec 1998) |
