tailieunhanh - Mononeuritis

Mononeuritis multiplex involves damage to at least 2 separate nerve areas. This condition can become progressively worse over time. The damage to the nerves involves destruction of the axon (ie, the part of the nerve cell that is analogous to the copper part of a wire), thus interfering with nerve conduction. Common causes of damage include a lack of oxygen from decreased blood flow or inflammation of blood vessels. Approximately 33% of cases originate from unidentifiable causes. | Mononeuritis Pathophysiology Mononeuritis multiplex involves damage to at least 2 separate nerve areas. This condition can become progressively worse over time. The damage to the nerves involves destruction of the axon ie the part of the nerve cell that is analogous to the copper part of a wire thus interfering with nerve conduction. Common causes of damage include a lack of oxygen from decreased blood flow or inflammation of blood vessels. Approximately 33 of cases originate from unidentifiable causes. Symptoms Numbness Tingling Abnormal sensation Burning pain - Dysesthesia Difficulty moving a body part - Paralysis Lack of controlled movement of a body part Physical Loss of sensation and movement may be associated with dysfunction of specific nerves. Examination reveals preservation of reflexes and good strength except in regions more profoundly affected. Some common findings of mononeuritis multiplex may include the following not listed in order of frequency Sciatic nerve dysfunction Femoral nerve dysfunction Common peroneal nerve dysfunction Axillary nerve dysfunction Radial nerve dysfunction Median nerve dysfunction Ulnar nerve dysfunction Tardive ulnar palsy Peroneal nerve palsy Autonomic dysfunction - The part of the nervous system that controls involuntary bodily functions such as the glands and the heart Radiculopathy Radiculopathy is not a specific condition but rather a description of a problem in which one or more nerves are affected and do not work properly a neuropathy
