What is bulbar involvement with polio?

In bulbar polio the virus attacks the brainstem, and the nerve centres that control swallowing and talking are damaged. Secretions collect in the throat and may lead to suffocation by blocking the airway. Some 5 to 10 percent of persons afflicted with paralytic polio die, usually…

What is the difference between Type 1 Type 2 and Type 3 polio?

Type 1 causes paralysis in about 1 in 200 infections; Type 2 was last recorded in 1999; Type 3 is less virulent than type 1, causing paralysis in about 1 in 1000 cases.

How is Guillain Barre Syndrome different from polio?

Guillain-Barré syndrome is an acute demyelinating polyneuropathy and, in the postpolio era, is the most common cause of generalized paralysis. The major symptom is rapidly progressive paralysis, which, unlike in polio, is symmetrical.

What does bulbar mean?

Definition of bulbar : of or relating to a bulb specifically : involving the medulla oblongata bulbar polio.

What is bulbar disease?

Bulbar palsy is a set of conditions that can occur due to damage to the lower cranial nerves. Clinical features of bulbar palsy range from difficulty swallowing and a lack of a gag reflex to inability to articulate words and excessive drooling. Bulbar palsy is most commonly caused by a brainstem stroke or tumor.

Which type of polio is most common?

PV1 is the most commonly encountered form, and the one most closely associated with paralysis. Individuals who are exposed to the virus, either through infection or by immunization via polio vaccine, develop immunity.

What is the new name for polio?

The condition is called acute flaccid myelitis, or AFM. With over 300 reports of AFM from this year alone (158 confirmed cases as of Dec 14), the Center for Disease Control and Prevention (CDC) has recently launched an AFM Task Force to investigate this very serious disease.

What are the three poliovirus Sabin serotypes?

One such candidate is an inactivated vaccine produced from the attenuated Sabin strains. Oral polio vaccine was first introduced in 1961 and consists of a mixture of the three live attenuated poliovirus serotypes (Sabin types 1, 2 and 3), selected for their lower neurovirulence and reduced transmissibility.

What is type 2 polio?

cVDPV type 2 (cVDPV2) are the most prevalent, with 959 cases occurring globally in 2020. Notably, since the African Region was declared to have interrupted transmission of the wild poliovirus in August 2020, cVDPV are now the only form of the poliovirus that affects the African Region.

Is polio now called Guillain Barre?

They were renamed. Measles has been renamed roseola, fifth disease, etc; Polio has been renamed Guillain Barre, transverse myelitis, coxsackie, MS, cerebral palsy (we actually use more respirators today than we ever did iron lungs by the way it is just that iron lungs were too expensive and dangerous to keep using);

Can polio cause Guillain Barre?

We carefully examined 10 cases with onset of GBS within 10 weeks after immunization. Only 4 patients could recall recent symptomatic infection, and we found no specific agent in these cases. Our study suggests that live-attenuated polioviruses may, like other infectious viruses, sometimes trigger the GBS.

Where is the bulbar located?

An area of the brain composed of the cerebellum, medulla and pons. (Basically, the bulbar region is made up of the brain stem minus the midbrain and plus the cerebellum). The bulbar region is responsible for many involuntary functions that keep us alive.

What are bulbar signs and symptoms?

Bulbar weakness tends to give speech a slurred, nasal quality. It also can lead to frequent choking spells and make eating unpleasant and tiresome. Limb weakness alone is highly uncommon and can be seen in only 5% of MG patients. In some rare cases, weakness may spread to muscles in the chest that control breathing.

What are bulbar signs?

Bulbar palsy symptoms Tongue – weak and wasted and sits in the mouth with fasciculations. Drooling – as saliva collects in the mouth and the patient is unable to swallow (dysphagia). Absent palatal movements. Dysphonia – a rasping tone due to vocal cord paralysis; a nasal tone if bilateral palatal paralysis.

Where is bulbar?

Is polio now called Guillain Barré?

What are the two types of polio vaccines?

Inactivated polio vaccine (IPV) is the only polio vaccine that has been given in the United States since 2000. IPV is given by shot in the leg or arm, depending on the patient’s age. Oral polio vaccine (OPV) is used in other countries. CDC recommends that children get four doses of polio vaccine.
