| immune deficiency diseases | Those diseases in which immune reactions are suppressed or reduced. Reasons may include congenital absence of B and/or T lymphocytes or viral killing of helper lymphocytes (see HIV). (18 Nov 1997) |
|---|---|
| immunologic diseases | Disorders caused by abnormal or absent immunologic mechanisms, whether humoral, cell-mediated or both. (12 Dec 1998) |
| infant, newborn, diseases | Diseases of newborn infants present at birth (congenital) or developing within the first month of birth. It does not include hereditary diseases not manifesting at birth or within the first 30 days of life nor does it include inborn errors of metabolism. Both hereditary diseases and metabolism, inborn errors are available as general concepts. (12 Dec 1998) |
| inflammatory bowel diseases | Chronic, non-specific disorders of unknown aetiology. Includes crohn disease and ulcerative colitis. Extracolonic manifestations are often associated with inflammatory bowel disease (ibd) and involve the liver, joints and skin. (12 Dec 1998) |
| injuries, poisonings, and occupational diseases | Disorders representing collectively the results of assault by external forces, rather than by organic or physiologic dysfunction or by pathogens. (12 Dec 1998) |
| intestinal diseases, parasitic | Infections of the intestines with a parasite. They are caused most commonly by intestinal nematodes (roundworms) and cestodes (tapeworms). (12 Dec 1998) |
| iris diseases | Diseases, dysfunctions, or disorders of or located in the iris. (12 Dec 1998) |
| obesity-related diseases | Obesity increases the risk of developing a number of diseases including: type 2 (adult-onset) diabetes high blood pressure (hypertension) stroke (cerebrovascular accident or cva) heart attack (myocardial infarction or mi) heart failure (congestive heart failure) cancer (only certain forms such as prostate and colon cancer) gallstones and gall bladder disease (cholecystitis) gout and gouty arthritis osteoarthritis (degenerative arthritis) of the knees, hips, and the lower back sleep apnea (failure to breath normally during sleep, lowering blood oxygen) pickwickian syndrome (obesity, red face, underventilation, and drowsiness). (12 Dec 1998) |
| occupational diseases | Diseases due to factors involved in one's employment. (12 Dec 1998) |
| orbital diseases | Diseases of the bony orbit and contents except the eyeball. (12 Dec 1998) |
| otorhinolaryngologic diseases | General or unspecified diseases of the ear, nose, and throat. (12 Dec 1998) |
| ear diseases | Diseases of the ear, general or unspecified. (12 Dec 1998) |
| tick-borne diseases | Bacterial, viral, or parasitic diseases transmitted to humans and animals by the bite of infected ticks. The families ixodidae and argasidae contain many bloodsucking species that are important pests of man and domestic birds and mammals and probably exceed all other arthropods in the number and variety of disease agents they transmit. Many of the tick-borne diseases are zoonotic. (12 Dec 1998) |
| endemic diseases | The constant presence of diseases or infectious agents within a given geographic area or population group. It may also refer to the usual prevalence of a given disease with such area or group. It includes holoendemic and hyperendemic diseases. A holoendemic disease is one for which a high prevalent level of infection begins early in life and affects most of the child population, leading to a state of equilibrium such that the adult population shows evidence of the disease much less commonly than do children (malaria in many communities is a holendemic disease). A hyperendemic disease is one that is constantly present at a high incidence and/or prevalence rate and affects all groups equally. (12 Dec 1998) |
| transport diseases | Single gene defect diseases in which there is an inability to transport particular small molecules across membranes. Examples are aminoacidurias such as cystinuria, iminoglycinuria, Hartup disease, Fanconi disease. (18 Nov 1997) |
