What is residual poliomyelitis?
Overview. Post-polio syndrome refers to a cluster of potentially disabling signs and symptoms that appear decades — an average of 30 to 40 years — after the initial polio illness. Polio once resulted in paralysis and death. However, the inactivated polio vaccine greatly reduced polio’s spread.
What is post-polio residual paralysis?
Post-polio syndrome (PPS) is a disorder of the nerves and muscles. It happens in some people many years after they have had polio. PPS may cause new muscle weakness that gets worse over time, pain in the muscles and joints, and tiredness. People with PPS often feel exhausted.
What is bulbar poliomyelitis?
Bulbar Paralytic Poliomyelitis Bulbar poliomyelitis results from paralysis of muscle groups innervated by the cranial nerves, especially those of the soft palate and pharynx, which may present as dysphagia, nasal speech, and sometimes dyspnea.
What is the cycle of polio?
The replication cycle of poliovirus is initiated by binding to the cell surface receptor CD155 (1). The virion is taken up via endocytosis, and the viral RNA is released (2). Translation of the viral RNA occurs by an IRES-mediated mechanism (3). The polyprotein is cleaved, yielding mature viral proteins (4).
What is bulbar polio?
Can polio be reactivated?
The theory that the polio virus may lie dormant in your body, causing post-polio syndrome when it becomes reactivated at a later stage, has been disproven. It’s not clear why only some people who’ve had polio develop post-polio syndrome.
What is the incubation period of poliomyelitis?
The incubation period for nonparalytic poliomyelitis is 3 to 6 days. For the onset of paralysis in paralytic poliomyelitis, the incubation period is usually 7 to 21 days.
What is the bulbar?
neurological disorders (In this context, the term bulbar refers to the medulla oblongata, which looks like a swelling, or bulb, at the top of the spinal cord.) Damage to the 9th through 12th cranial nerves, the bulbar nerves, causes impairment of swallowing and speech and…
How are internally studentized residuals used to identify outliers?
The good thing about internally studentized residuals is that they quantify how large the residuals are in standard deviation units, and therefore can be easily used to identify outliers: An observation with an internally studentized residual that is larger than 3 (in absolute value) is generally deemed an outlier.
What are the four stages of poliomyelitis?
The course of the disease is divided into four stages: Prodromal Stage or Pre-Paralytic Stage – few hours to a few days and 1 to 3 days is the usual duration. Headache. Sore throat. Malaise. Slight Cough. Diarrhea or constipation. Backache.
How are tendon transfers done for poliomyelitis?
Patient is given combination of stretching,strengthening and calliperization. Tailor-made calipers can prevent the deformity from aggravating. Tendon transfers may be done for compromising balance on that side.
