Poliomyletis
1. What are the forms of polio
1. Abortive polio: mild form, most recover fully 2. non-paralytic polio: most severe form, associated with aseptic meningitis, most recover fully 3. paralytic polio: virus attacks nerves that control skeletal and respiratory muscles that may result in death
1. what does the virus affect 2. What is the dysfunction
1. anterior motor neurons of spinal cord and brain stem -causes a loss of motor neurons and denervation of their associated skeletal muscles -FLACCID ASYMMETRIC WEAKNESS -Muscle atrophy -Autonomic functions can be affected
1. Prevention for polio?
1. children between ages of 2 months - 6 years recommended to have 4 doses of inactivated polio vaccination -90% effective
1. What are the clinical features 2. What is Post polio syndrome? 3. What are the symptoms of PPS
1. headache, slight fever, sore throat, red throat, discomfort, uneasiness, MAY BE ASYMPTOMATIC like 95% of the cases 2. caused by death of individual nerves that remain damaged after initial polio attack 3. fatigue, slowly progressive muscle weakness, muscular atrophy, muscle/joint pain, scoliosis common, joint paint, skeletal deformities -some experience minor symptoms other can develop spinal muscular atrophy and type of Lou Gehrig's disease -it is rarely life threatening
1. What are the risk factors for polio? 2. What is it? 3. How do you get it? 4. Time from receiving virus to time of symptoms....
1. lack of immunization 2. communicable viral disease through direct contact with infected secretions, clinical polio affects CNS 3. mainly affects young children, virus transmitted person to personal through faecal-oral route or by contaminated water or food --it multiplies in the intestine and can invade nervous system and cause paralysis 4. 1-2 weeks but can manifest within 35 days
1. people who experienced minimal symptoms from original PP will experience _______ symptoms of PPS 2. the same symptoms can result from___ 3. How many become paralyzed
1. mild (more severe Polio----more severe PPS) 2. disuse of muscles and joints 3. less than 1-2% (more adults die)
1. What are symptoms used to diagnose polio 2. How do they confirm diagnosis
1. neck and back stiffness, abnormal reflexes, difficulty swallowing and breathing 2. sample of throat secretions, stool or cerebrospinal fluid (spinal tap) is examined for level of antibodies to poliovirus
1. What is the treatment for polio?
1. no cure only supportive care: bed rest, pain relievers, portable ventilators to assist breathing, moderate exercise to prevent deformity and loss of function and to improve functional independence, nutritious diet (modified wheel chairs for rough terrains)
