| polioencephalitis infectiva | A unique encephalitis, presumably viral in origin, which followed the influenza pandemic of 1914-1918. Symptoms included ophthalmoplegia and marked somnolence, and in many survivors, the delayed development of Parkinson's disease; the basis for postencephalitic Parkinsonism. Synonym: encephalitis lethargica, polioencephalitis infectiva. (05 Mar 2000) |

| polioencephalomalacia | A noninfectious disease of ruminants characterised by a tissue-thiamine deficiency and by amaurosis and strabismus, followed by recumbency, opisthotonos, and convulsions. Synonym: cerebrocortical necrosis. (05 Mar 2000) |
| polioencephalomeningomyelitis | Infla mmation of the gray matter of the brain and spinal cord and of the meningeal covering of the parts. Origin: polio-+ G. Enkephalos, brain, + meninx, membrane, + myelon, marrow, + -itis, inflammation (05 Mar 2000) |
| polioencephalomyelitis | Synonym: poliomyeloencephalitis. (05 Mar 2000) |
| polioencephalopathy | Any disease of the gray matter of the brain. Origin: polio-+ G. Enkephalos, brain, + pathos, suffering (05 Mar 2000) |
| poliomyelencephalitis | Acute anterior poliomyelitis with pronounced cerebral signs. Synonym: polioencephalomyelitis, poliomyelencephalitis. Origin: polio-+ G. Myelon, marrow, + enkephalos, brain, + -itis, inflammation (05 Mar 2000) |
| poliomyelitis | <disease, virology> An acute viral disease, occurring sporadically and in epidemics and characterised clinically by fever, sore throat, headache and vomiting, often with stiffness of the neck and back. In the minor illness these may be the only symptoms. The major illness, which may or may not be preceded by the minor illness, is characterised by involvement of the central nervous system, stiff neck, pleocytosis in the spinal fluid and perhaps paralysis. There may be subsequent atrophy of groups of muscles, ending in contraction and permanent deformity. The major illness is called acute anterior poliomyelitis, infantile paralysis and Heine Medin disease. The disease is now largely controlled by vaccines. Origin: Gr. Myelos = marrow (18 Nov 1997) |
| poliomyelitis immune globulin | A sterile solution of globulin's that contains those antibodies normally present in adult human blood; it is a passive immunologic agent that attenuates or prevents poliomyelitis, measles, and infectious hepatitis, and confers temporary but significant protection against paralytic polio. Synonym: poliomyelitis immunoglobulin. (05 Mar 2000) |
| poliomyelitis immunoglobulin | poliomyelitis immune globulin (human) |
| poliomyelitis vaccines | Inactivated poliovirus vaccine (IPV), an aqueous suspension of inactivated strains of poliomyelitis virus (types 1, 2, and 3) used by injection; has largely been replaced by the oral vaccine. See: Salk vaccine. (05 Mar 2000) |
| poliomyelitis virus | The picornavirus (genus Enterovirus) causing poliomyelitis in humans; the route of infection is the alimentary tract, but the virus may enter the bloodstream and nervous system, sometimes causing paralysis of the limbs and, rarely, encephalitis; many infections are inapparent; serologic types 1, 2, and 3 are recognised, type 1 being responsible for most paralytic poliomyelitis and most epidemics. Synonym: poliovirus hominis, poliovirus. (05 Mar 2000) |
| poliomyelitis, bulbar | A serious form of poliomyelitis in which the medulla oblongata is affected, and in which there may be dysfunction of the swallowing mechanism, and respiratory and circulatory distress. (12 Dec 1998) |
| poliomyeloencephalitis | Acute anterior poliomyelitis with pronounced cerebral signs. Synonym: polioencephalomyelitis, poliomyelencephalitis. Origin: polio-+ G. Myelon, marrow, + enkephalos, brain, + -itis, inflammation (05 Mar 2000) |
| poliomyelopathy | Any disease of the gray matter of the spinal cord. Origin: polio-+ G. Myelon, marrow, + pathos, suffering (05 Mar 2000) |
| poliosis | A patchy absence or lessening of melanin in hair of the scalp, brows, or lashes, due to lack of pigment in the epidermis; it occurs in several hereditary syndromes but may be caused by inflammation, irradiation, or infection such as herpes zoster. Synonym: trichopoliosis. Origin: G., fr. Polios, gray (05 Mar 2000) |
