Guillain-Barre Syndrome Essay -- Medical Science Scientific Medicine E
Guillain-Barre SyndromeGuillain-Barre Syndrome, or acute inflammatory demyelinating polyneuropathy, is a self-limiting disease characterized by areflexia and acute progressive motor weakness of at least unmatchable limb. Other symptoms include motor weakness of the extremities and face, loss or decrement of deep tendon reflexes, decreased sensation throughout the body,ophthalmoplegia, and ataxia. In crude(a) cases respiratory harm and autonomic disfunction may overtake. Respiratory failure results from the demyelination of the phrenic and intercostal nerves. Consequently, the person loses the ability to inhale and exhale. Autonomic dysfunction resulting from the demyelination of the sympathetic and vagus nerves can lead to cardiac arrhythmias, tachycardia, postural hypotension, and hypertension. Analysis of the cerebral spinal fluid (CSF) shows increased protein concentration with few cells. Other tests reveal a decreased nerve conduction f number resulting from segmental demye lination with mononuclear cell infiltration. In 70% of the afflicted individuals, the symptoms of Guillain-Barre Syndrome (GBS) occur within two weeks following infection. Clinical diagnosis is based on the presence of albumino-cytological dissociation in the CSF. Following the onset, motor weakness more and more deteriorates for four weeks and may lead to respiratory failure and cardiac instability. If either respiratory failure or cardiac abnormalities occur, the patient will be placed in the intensive care unit and closely monitored. at last the persons condition will cease to deteriorate, and he/she will enter a plateau period of two to four weeks during which little or no change will occur. Following the plateau stage, the patient will step by step rec... ...Guillain Barre syndrome following immunisation with Haemophilusinfluenzae type b conjugate vaccine. Europ. J.
