| acute haemorrhagic leukoencephalitis | A fulminating demyelinating disorder of the central nervous system that affects mainly children and young adults. Almost always preceded by a respiratory infection, characterised by the abrupt onset of fever, headache, confusion, and nuchal rigidity, soon followed by focal seizures, hemiplegia, or quadriplegia, brainstem findings, and coma; the CSF shows evidence of an inflammatory process; due to the massive destruction of the white matter of one or both hemispheres, often accompanied by similar destruction of the white matter of the brainstem and cerebellar peduncles; of unknown aetiology. Synonym: acute haemorrhagic leukoencephalitis, acute necrotizing haemorrhagic leukoencephalitis. (05 Mar 2000) |

| African haemorrhagic fever | Haemorrhagic fever associated with the morphologically similar but antigenically distinct Marburg and Ebola viruses. See: viral haemorrhagic fever. (05 Mar 2000) |
| Argentinean haemorrhagic fever | A form of haemorrhagic fever observed in South America, seemingly transmitted by contact from rodents to man and caused by the Junin virus, a member of the family Arenaviridae. (05 Mar 2000) |
| Argentine haemorrhagic fever virus | A member of the Arenaviridae. (05 Mar 2000) |
| bolivian haemorrhagic fever | A febrile illness similar to Argentinian haemorrhagic fever but caused by the Machupo virus, a member of Arenaviridae. (27 Sep 1997) |
| Bolivian haemorrhagic fever virus | A member of the Arenavirus group of single-stranded RNA viruses also known as Machupo virus; primary reservoir in rodents; produces multiple abnormalities in coagulation system including widespread capillary leak syndrome, which can be fatal. (05 Mar 2000) |
| Brazilian haemorrhagic fever | Fulminating sepsis, usually beginning with conjunctivitis, characterised by purpuric skin lesions, a high fatality rate; thought to be due to Haemophilus aegyptius. Synonym: Brazilian haemorrhagic fever, Brazilian purpuric fever. (05 Mar 2000) |
| rabbit haemorrhagic disease | A highly infectious disease of rabbits, caused by a calicivirus and characterised by haemorrhagic lesions, particularly affecting the lungs and liver; since it was first identified in China in 1984, it has been reported from Korea, it has spread through Europe, and it has reached North Africa and Mexico.

| Manchurian haemorrhagic fever | A form of epidemic haemorrhagic fever caused by the Hantaan virus of the genus hantavirus. Synonym: Manchurian haemorrhagic fever. (05 Mar 2000) |
| viral haemorrhagic fever | An epidemic viral illness seen in southern Sudan and Zaire, caused by the Ebola virus. The illness is characterised by fever, malaise, muscle aches, respiratory symptoms, diarrhoea, vomiting, epistaxis, haemoptysis, haematemesis, rash, tremors and subconjunctival haemorrhages. Transmitted by close bodily contact with infected individuals (blood, faeces and body fluids). Incubation is-21 days with initial symptoms of fever and headache. There is no specific treatment and death can occur within 10 days. (27 Sep 1997) |

| chronic haemorrhagic villous synovitis | <radiology> Monoarthritis, young adults, erosions on BOTH sides of joint (!), probably inflammatory, haemosiderin deposited in synovium, articular cartilage preserved (despite extensive marginal erosions; similar to gout), NO calcification Differential diagnosis: TB (associated atrophy of muscle and bone), rheumatoid arthritis (symmetrical), synovial sarcoma (with or without calcified; outside joint), synovial osteochondromatosis (12 Dec 1998) |
