| standardised mortality ratio | The ratio of the number of events observed in a population to the number that would be expected if the population had the same distribution as a standard or reference population. (05 Mar 2000) |
|---|---|
| neonatal mortality rate | The number of children dying under 28 days of age divided by the number of live births that year. The neonatal mortality rate in the united states, which was 8.4 per 1,000 live births in 1980, declined to 5.8 per 1,000 live births in 1990. (12 Dec 1998) |
| infant mortality | Perinatal, neonatal, and infant deaths in a given population. (12 Dec 1998) |
| infant mortality rate | The number of children dying under a year of age divided by the number of live births that year. The infant mortality rate in the united states, which was 12.5 per 1,000 live births in 1980, fell to 9.2 per 1,000 live births in 1990. (12 Dec 1998) |
| type II mortality | <epidemiology> A mortality schedule in which all hosts are assumed to die at a constant rate. This constant rate is equal to the inverse of the life expectancy. (05 Dec 1998) |
| type I mortality | <epidemiology> A mortality schedule in which all hosts are assumed to live for a fixed number of years equal to the life expectancy. (05 Dec 1998) |
| foetal mortality rate | <epidemiology> The ratio of foetal deaths divided by the sum of the births (the live births + the foetal deaths) in that year. In the United States, the foetal mortality rate plummeted from 19.2 per 1,000 births in 1950 to 9.2 per 1,000 births in 1980. (12 Dec 1998) |
| antibiotic induced enteritis | <pathology> A condition where the normal intestinal bacteria (useful for digestion) are killed by the use of an antibiotic resulting in symptoms. (27 Sep 1997) |
| campylobacter enteritis | <pathology> A genus of bacteria that represents a number of different species that are pathogenic in man. Campylobacter jejuni is probably the second most common cause of waterborne diarrhoeal disease in the United States. Campylobacter pylori has been implicated as an aetiological factor in the development of gastritis and peptic ulcer disease. Common symptoms include abdominal pain, watery diarrhoea (may be bloody) and fever. (27 Sep 1997) |
| regional enteritis | A subacute chronic enteritis, of unknown cause, involving the terminal ileum and less frequently other parts of the gastrointestinal tract; characterised by patchy deep ulcers that may cause fistulas, and narrowing and thickening of the bowel by fibrosis and lymphocytic infiltration, with noncaseating tuberculoid granulomas that also may be found in regional lymph nodes; symptoms include fever, diarrhoea, cramping abdominal pain, and weight loss. Synonym: chronic cicatrizing enteritis, Crohn's disease, distal ileitis, regional ileitis, terminal ileitis, granulomatous enteritis. (05 Mar 2000) |
| granulomatous enteritis | Crohn's disease, a chronic inflammatory disease of the intestine primarily in the small and large intestines but which can occur anywhere in the digestive system between the mouth and the anus. Named after Burrill Crohn who described the disease in 1932. The disease usually affects persons in their teens or early twenties. It tends to be a chronic, recurrent condition with periods of remission and exacerbation. In the early stages, Crohn's disease causes small scattered shallow crater-like areas (erosions) called apthous ulcers in the inner surface of the bowel. With time, deeper and larger ulcers develop, causing scarring and stiffness of the bowel and the bowel becomes increasingly narrowed, leading to obstruction. Deep ulcers can puncture holes in the bowel wall, leading to infection in the abdominal cavity (peritonitis) and in adjacent organs.When only the large intestine (colon) is involved, the condition is called Crohn's colitis. When only the small intestine is involved, the condition is called crohn's enteritis. When only the end of the small intestine (the terminal ileum) is involved, it is termed terminal ileitis. When both the small intestine and the large intestine are involved, the condition is called crohn's enterocolitis (or ileocolitis). Abdominal pain, diarrhoea, vomiting, fever, and weight loss can be symptoms. Crohn's disease can be associated with reddish tender skin nodules, and inflammation of the joints, spine, eyes, and liver. Diagnosis is by barium enema, barium X-ray of the small bowel, and colonoscopy. Treatment includes medications for inflammation, immune suppression, antibiotics, or surgery. (the disease is also called regional enteritis). (12 Dec 1998) |

Synonym: chronic cicatrizing enteritis, Crohn's disease, distal ileitis, regional ileitis, terminal ileitis, granulomatous enteritis. (05 Mar 2000) |
| phlegmonous enteritis | Severe acute inflammation of the intestine, with edematous bowel wall infiltrated with pus. (05 Mar 2000) |
| mink enteritis virus | A parvovirus that causes enteritis of mink. (05 Mar 2000) |
| mucomembranous enteritis | An affection of the intestinal mucous membrane characterised by constipation or diarrhoea (sometimes alternating), colic, and the passage of pseudomembranous shreds or incomplete casts of the intestine. Synonym: mucoenteritis. (05 Mar 2000) |
