The middle cerebellar peduncle is the largest of the three cerebellar peduncles. It connects the pons and cerebellum.It consists almost entirely of fibers passing from the pons to the cerebellum (fibrocerebellar fibers); the fibers arise from the pontine nuclei and decussate within the pons before entering the peduncle [1] to end in the contralateral cerebellar hemisphere.
One option includes treatment for a disease or disorder that may be contributing to the balance problem, such as ear infection, stroke, multiple sclerosis, spinal cord injury, Parkinson's, neuromuscular conditions, acquired brain injury, cerebellar dysfunctions and/or ataxia, or some tumors, such as acoustic neuroma. Individual treatment will ...
Cerebellar stroke syndrome is a condition in which the circulation to the cerebellum is impaired due to a lesion of the superior cerebellar artery, anterior inferior cerebellar artery or the posterior inferior cerebellar artery.
This tension is forced and can cause lesions of the upper roots and trunk of the nerves of the brachial plexus. [25] Motorcycle accidents and sports injuries usually cause this type of injury to brachial plexus. [14] Upward traction also results in the broadening of the scapulo-humoral angle but this time the nerves of T1 and C8 are torn away.
Brachymetatarsia is a rare malformation that causes one or more toes to be abnormally short. The condition is characterized by a metatarsal arch shortness of more than 5 mm. The condition is more common in females, and the incidence reported in the literature ranges from 0.02% to 0.05%.
The cause is believed to be muscle tension or spasms within the affected musculature. [1] Diagnosis is based on the symptoms and possible sleep studies. [1] Treatment may include pain medication, physical therapy, mouth guards, and occasionally benzodiazepine. [1] It is a relatively common cause of temporomandibular pain. [1]
Administration of nitrous oxide anesthesia can precipitate subacute combined degeneration in people with subclinical vitamin B 12 deficiency, while chronic nitrous oxide exposure can cause it even in persons with normal B 12 levels. Posterior column dysfunction decreases vibratory sensation and proprioception (joint sense).
There are several causes of toxic optic neuropathy. [1] Among these are: ingestion of methanol (wood alcohol), ethylene glycol (automotive antifreeze), disulfiram (used to treat chronic alcoholism), halogenated hydroquinolones (amebicidal medications), ethambutol and isoniazid (tuberculosis treatment), and antibiotics such as linezolid and chloramphenicol as well as chloroquine and the related ...
