| dystrophia | <pathology> Any disorder arising from defective or faulty nutrition, especially the muscular dystrophies. Origin: L. Dystrophia, Gr. Trephein = to nourish (18 Nov 1997) |

| dystrophia adiposogenitalis | A disorder characterised primarily by obesity and hypogonadotrophic hypogonadism in adolescent boys; dwarfism is rare, and when present is thought to reflect hypothyroidism. Visual loss, behavioural abnormalities, and diabetes insipidus may occur. Frohlich's syndrome often is used synonymously for this disorder, although the original case involved a pituitary tumour; most cases are thought to result from hypothalamic dysfunction in areas regulating appetite and gonadal development. The most common causes are pituitary and hypothalamic neoplasms. Synonym: adiposis orchica, adiposogenital degeneration, adiposogenital dystrophy, adiposogenital syndrome, hypophysial syndrome, hypothalamic obesity with hypogonadism. Origin: L. Fr. G. Dys-, bad, + trophe, nourishment (05 Mar 2000) |
| dystrophia brevicollis | A condition marked by symptoms of dystrophia adiposogenitalis together with a deforming shortness of the neck, but without synostosis of the cervical vertebrae seen in Klippel-Feil syndrome. (05 Mar 2000) |
| dystrophia myotonica | <neurology> An inherited human neuromuscular disease classed as an autosomal dominant disease in which there is progressive muscle weakening and wasting. A triplet repeat syndromes (like fragile X syndrome), this most common adult form of muscular dystrophy is caused by expansion of the unstable trinucleotide repeat CTG in the 3' untranslated region on chromosome 19q13 (cAMP-dependent muscle protein kinase gene). Anticipation has been associated with further expansion of the repeat upon transmission to subsequent generations (the inheritance pattern is autosomal dominant), although contraction has been noted to occur as well. Especially severe neonatal cases have been born to affected mothers preferentially, suggesting a role for genomic imprinting as well. The classic physical signs include atrophy of facial muscles, cataracts, and delayed muscle relaxation. Detection of the expanded trinucleotide repeat is accomplished by PCR or Southern blot and expansion appears to correlate with decreased transcription of the protein kinase gene. Inheritance: autosomal dominant. (29 Dec 1997) |
| dystrophia ungulae | A condition of the hoof wall in the toe region of horses, characterised by loss of substance and change in character of the horn, most often as a sequela of mild chronic laminitis. Synonym: dystrophia ungulae, hollow wall. (05 Mar 2000) |
| achromia unguium | The occurrence of white spots or patches under the nails, of unknown cause; the decoloration may be total or in the form of lines (striate or transverse leukonychia) or dots (punctate leukonychia). Synonym: achromia unguium, canities unguium, leukopathia unguis. Origin: Leuko-+ G. Onyx (onych-), nail Apparent leukonychia, pallor of the nail not due to subungual air bubbles. (05 Mar 2000) |
| arcus unguium | Origin: L, prop, a little moon. See Lunule. <anatomy> Same as Lunule. Source: Websters Dictionary (01 Mar 1998) |
| canities unguium | The occurrence of white spots or patches under the nails, of unknown cause; the decoloration may be total or in the form of lines (striate or transverse leukonychia) or dots (punctate leukonychia). Synonym: achromia unguium, canities unguium, leukopathia unguis. Origin: Leuko-+ G. Onyx (onych-), nail Apparent leukonychia, pallor of the nail not due to subungual air bubbles. (05 Mar 2000) |
| gryposis unguium | Enlargement with increased thickening and curvature of the fingernails or toenails. Synonym: gryposis unguium, onychogryphosis. Origin: onycho-+ G. Gryposis, a curvature (05 Mar 2000) |
| scabrities unguium | Thickening and distortion of the nails. (05 Mar 2000) |
| selene unguium | Synonym: lunula. Origin: G. Selene, moon; gen. Pl. Of L. Unguis, nail (05 Mar 2000) |
| defluvium unguium | A falling (or loss) of nails. (05 Mar 2000) |
| tinea unguium | The most common fungus infection of the nails (onychomycosis). Onychomycosis makes the nails look white and opaque, thickened, and brittle. Older women (perhaps because oestrogen deficiency may increase the risk of infection). And men and women with diabetes or disease of the small blood vessels (peripheral vacscular disease) are at increased risk. Artificial nails (acrylic or wraps ) increase the risk because when an artificial nail is applied, the nail surface is usually abraded with an emery board damaging it, emery boards can carry infection, and. Water can collect under the nail creating a moist, warm environment for fungal growth. Alternative names include ringworm of the nails and dermatophytic onychomycosis. (17 Dec 1998) |
| trichophytosis unguium | Fungus infection of the nail plates. See: onychomycosis. (05 Mar 2000) |
