| polio immunization | <virology> The vaccines available for vaccination against polio are opv (oral polio vaccine) and ipv (inactivated polio vaccine). Opv is still the preferred vaccine for most children. As its name suggests, it is given by mouth. Ipv, or inactivated polio vaccine is given as a shot in the arm or leg. Infants and children should be given four doses of opv. The doses are given at 2 months, 4 months, 6-18 months and 4-6 years of age. Persons allergic to eggs or the drugs neomycin or streptomycin should receive opv, not the injectable ipv. Conversely, ipv should be given if the vaccine recipient is on long-term steroid (cortisone) therapy, has cancer, or is on chemotherapy or if a household member has aids or there is an unimmunised adult in the house.

| poliodystrophia cerebri progressiva infantilis | Familial progressive spastic paresis of extremities with progressive mental deterioration, with development of seizures, blindness and deafness, beginning during the first year of life, and with destruction and disorganization of nerve cells of the cerebral cortex. Synonym: Alpers disease, Christensen-Krabbe disease, progressive cerebral poliodystrophy. (05 Mar 2000) |

| polioencephalitis | Inflammation of the gray matter of the brain, either of the cortex or of the central nuclei; as contrasted to inflammation of the white matter. Origin: polio-+ G. Enkephalos, brain, + -tis, inflammation (05 Mar 2000) |
| 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.

| 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) |
