| paleostriatal syndrome | <syndrome> An intention tremor beginning in one extremity, gradually increasing in intensity, and subsequently involving other parts of the body. Synonym: progressive cerebellar tremor. Facial paralysis, otalgia, and herpes zoster resulting from viral infection of the seventh cranial nerve and geniculate ganglion, a form of juvenile paralysis agitans associated with primary atrophy of the pallidal system. Synonym: paleostriatal syndrome, pallidal syndrome. Synonym: Ramsay Hunt's syndrome. (05 Mar 2000) |

| van der Hoeve's syndrome | <syndrome> A subtype of osteogenesis imperfecta in which progressive conductive hearing loss begins in childhood because of stapedial fixation. (05 Mar 2000) |
| vanished testis syndrome | <syndrome> Absence of both testes in a male with normal chromosomes (XY) and otherwise normal genitalia at birth and during childhood. Testes were present in at least the first trimester of gestation, but vanished sometime thereafter. (05 Mar 2000) |
| vanishing lung syndrome | <syndrome> Progressive decrease of radiographic opacity of the lung caused by accelerated development of emphysema or rapid cystic destruction of the lung from infection. (05 Mar 2000) |
| pallidal syndrome | <syndrome> An intention tremor beginning in one extremity, gradually increasing in intensity, and subsequently involving other parts of the body. Synonym: progressive cerebellar tremor. Facial paralysis, otalgia, and herpes zoster resulting from viral infection of the seventh cranial nerve and geniculate ganglion, a form of juvenile paralysis agitans associated with primary atrophy of the pallidal system. Synonym: paleostriatal syndrome, pallidal syndrome. Synonym: Ramsay Hunt's syndrome. (05 Mar 2000) |
| pallister-killian syndrome | <syndrome> A condition with multiple malformations at birth and mental retardation due to isochromosome 12p mosaicism (an abnormal chromosome 12 in some cells). (12 Dec 1998) |
| Raeder's paratrigeminal syndrome | <syndrome> A postganglionic Horner's syndrome associated with trigeminal nerve dysfunction caused by involvement of the carotid sympathetic plexus, near Mechel' cave. (05 Mar 2000) |
| Ganser's syndrome | <syndrome> A psychotic-like condition, without the symptoms and signs of a traditional psychosis, occurring typically in prisoners who feign insanity; e.g., such a person, when asked to multiply 6 by 4, will give 23 as the answer, or he will call a key a lock.

| Gardner-Diamond syndrome | <syndrome> A condition, usually occurring in women, in which the individual bruises easily (purpura simplex) and the ecchymoses tend to enlarge and involve adjacent tissues, resulting in pain in the affected parts; so-called because similar lesions are produced by inoculation of the individual's blood or various components of red blood cells and it is thought to be a form of localised autosensitization, although no specific antibodies have been demonstrable; in some individuals, there seems to be a psychogenic mechanism. Synonym: Gardner-Diamond syndrome, psychogenic purpura. (05 Mar 2000) |
| Gardner's syndrome | <syndrome> Multiple polyposis predisposing to carcinoma of the colon; also multiple tumours, osteomas of the skull, epidermoid cysts, and fibromas; autosomal dominant inheritance. (05 Mar 2000) |
| gardner syndrome | <radiology> Autosomal dominant, adenomas leading to colon carcinoma (treatment: colectomy), periampullary carcinoma, soft-tissue lesions, sebaceous cysts, subcutaneous fibromas, leiomyomas, lipomas, bony lesions, osteomas (especially in sinuses), exostoses, cortical thickening, dental abnormalities (caries, extra teeth, odontomas) see: polyposis syndromes (12 Dec 1998) |
| gareis-mason syndrome | <syndrome> An inherited (genetic) syndrome with characteristic features including (1) neurologically: mental retardation and aphasia (lack of speech); (2) limbs: adducted (clasped) thumbs, absent extensor pollicis longus and/or brevis muscles to the thumb, shuffling gait, and leg spasticity; (3) growth: small body size; (4) skeleton: lumbar lordosis (sway back). The syndrome is inherited as an X-linked trait and so affects mainly boys. Alternative names include MASA syndrome (MASA stands for mental retardation, aphasia, shuffling gait, and adducted thumbs), clasped thumb and mental retardation, congenital clasped thumb with mental retardation, and adducted thumb with mental retardation. (12 Dec 1998) |
| malabsorption syndrome | <syndrome> A variety of conditions in which digestion and absorption in the small intestine are impaired. Multiple causes including lymphoma, amyloid and other infiltrations, Crohn's disease, gluten sensitive enteropathy and the sprue syndrome in which the villi atrophy for unknown reasons. (18 Nov 1997) |
| vasculocardiac syndrome of hyperserotonaemia | An obsolete term for carcinoid syndrome. (05 Mar 2000) |
| pancoast's syndrome | <syndrome> Destructive lesions of the thoracic inlet with involvement of the brachial and sympathetic plexus or carcinoma of the lung apex. It is characterised by pain in the shoulder region radiating toward the axilla and scapula, sensory and motor disorders and wasting of the muscles of the hand, the bernard-horner syndrome, and compression of the blood vessels with oedema.
