| Marie-Strumpell disease | <rheumatology> A polyarthritis involving the spine, which is characterised by progressive, painful stiffening of the joints and ligaments. It almost exclusively affects young men. Interestingly the disease seems to be associated with HLA B27, those with this histocompatability antigen are 300 times more likely to get the disease, 90% of sufferers have HLA B27 (18 Nov 1997) |

| Marion's disease | A congenital obstruction of the posterior urethra. (05 Mar 2000) |
| Recklinghausen's disease of bone | Rarefying osteitis with fibrous degeneration and formation of cysts, and with the presence of fibrous nodules on the affected bones. It is due to marked osteoclastic activity secondary to hyperfunction of the parathyroid glands. (12 Dec 1998) |
| Recklinghausen's disease type I | type 2 neurofibromatosis |
| Gerhardt-Mitchell disease | Disease marked by paroxysmal, bilateral vasodilatation, particularly of the extremities, with burning pain, and increased skin temperature and redness. (12 Dec 1998) |
| Gerhardt's disease | Disease marked by paroxysmal, bilateral vasodilatation, particularly of the extremities, with burning pain, and increased skin temperature and redness. (12 Dec 1998) |
| vertebral-basilar artery disease | <cardiology> Aortic arch syndrome, also referred to by many as vertebral-basilar artery disease, carotid artery occlusive syndrome and subclavian steal syndrome is characterised by a constellation of signs and symptoms which occur secondary to abnormalities in the major arteries which extend off of the aortic arch. These abnormalities are structural and most often secondary to the effects of atherosclerosis, blood clots, trauma or a congenital abnormality. Symptoms of this condition include various neurologic symptoms, reduction in pulse and changes in blood pressure. (27 Sep 1997) |
| Gerlier's disease | A paroxysmal attack of severe vertigo, not accompanied by deafness or tinnitus, which affects young to middle-aged adults, often following a non-specific upper respiratory infection; due to unilateral vestibular dysfunction. Synonym: endemic paralytic vertigo, epidemic vertigo, Gerlier's disease, kubisagari, kubisagaru, paralyzing vertigo. (05 Mar 2000) |
| Martin's disease | A periosteoarthritis of the foot from excessive walking. (05 Mar 2000) |
| Carrington's disease | <radiology> Idiopathic, associated with allergies and desensitization, variant of Loeffler pneumonia, treatment: corticosteroids Findings: reverse pulmonary oedema pattern (= Loeffler's), areas of consolidation persists (days to weeks) see: eosinophilic lung disease (12 Dec 1998) |
| Carrion's disease | A generalised, acute, febrile, endemic, and systemic form of bartonellosis; marked by high fever, rheumatic pains, progressive, severe anaemia, and albuminuria. Synonym: Carrion's disease. (05 Mar 2000) |
| gestational trophoblastic disease | (choriocarcinoma, molar pregnancy) a type of cancer associated with pregnancy in which a grape-like mole develops in the womb instead of a foetus. (16 Dec 1997) |
| parkinson disease | Progressive, degenerative disease of unknown aetiology characterised by rhythmic tremor of the limbs, stooped posture, slowness of voluntary movements, and masklike facial expression. Pathologically there is nerve cell loss in the melanin-containing cells in the brainstem and a corresponding reduction in dopamine levels in the corpus striatum. Lewy bodies are present in the substantia nigra and locus coeruleus. (12 Dec 1998) |
| parkinson disease, postencephalitic | A form of parkinson disease due to degeneration of the corpus striatum or substantia nigra, frequently occurring as a sequel of lethargic encephalitis. The early age of onset, the rapid progression of symptoms and signs of stabilization, and the presence of a variety of other neurological disorders (sociopathic behaviour, tics, spasms, oculogyric crises and other restricted motor disorders, breathing arrhythmias, hyperphagia, and bizarre movements, postures, and gaits) distinguish this disease from the one described by parkinson. (12 Dec 1998) |
| parkinson disease, symptomatic | Symptoms of parkinson disease induced by drugs, or following cerebral arteriosclerosis, brain tumour, or other central nervous system disorders except encephalitis, which is parkinson disease, postencephalitic. (12 Dec 1998) |
