1/4. filtration of cerebrospinal fluid for acute demyelinating neuropathy in systemic lupus erythematosus.We report a patient with systemic lupus erythematosus complicated by an acute demyelinating neuropathy. Conventional therapy with intravenous immunoglobulins and immunoadsorption complemented by pulse methylprednisolone and cyclophosphamide failed. Institution of filtration of the cerebrospinal fluid was followed by a rapid improvement of the paresis.- - - - - - - - - - ranking = 1keywords = demyelinating (Clic here for more details about this article) |
2/4. guillain-barre syndrome: perspectives with infants and children.An acute flaccid paraparesis or ascending quadriparesis in an infant or child constitutes a very important pediatric neurology emergency. The guillain-barre syndrome (GBS) is the most frequent cause. This is primarily an autoimmune, post-infectious, demyelinating, peripheral nervous system process. A small percentage of children develop a primary axonal process not unlike that identified more commonly in china. Because of the potential for acute respiratory compromise, any child suspected of having GBS needs immediate hospitalization. The major considerations in differential diagnosis include transverse myelitis, toxic neuropathies, tick paralysis, infantile botulism, myasthenia gravis, and dermatomyositis. On occasion, some younger children present with an acute severe pain syndrome that may mask as a pseudo-encephalopathy. Another clinical variant is the Miller-Fisher syndrome characterized by ataxia, ophthalmoparesis, and areflexia. This is associated with a high frequency of the anti-GQ-1-b antibodies. Although most children with GBS have a relatively benign clinical course, some become very ill and require intubation with intensive care monitoring. Immunomodulating treatment should be used for any child who loses the ability to walk. To date, no well-controlled study has been completed analyzing the relative merits of the two most commonly used therapies, namely plasmapheresis or intravenously administered immunoglobulin.- - - - - - - - - - ranking = 0.2keywords = demyelinating (Clic here for more details about this article) |
3/4. Chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) with hypertrophic spinal radiculopathy mimicking neurofibromatosis.This report illustrates a case of chronic inflammatory demyelinating polyradiculoneuropathy (CIDP) masquerading as neurofibromatosis due to multifocal enlargements of spinal nerve roots. The patient initially complained of intermittent numbness of the hands and leg weakness at age 62. Nerve conduction velocities were reported to be abnormally slow, suggesting a diagnosis of demyelinating neuropathy. A complaint of progressive lower back pain 4 years later prompted a lumbar CT myelogram, which demonstrated bilateral nerve root enlargements. A biopsy of an enlarged lumbar root obtained during decompressive laminectomy was interpreted as consistent with a plexiform neurofibroma. He suffered recurrent paraparesis, at times with a sensory level indicating spinal cord compression, which responded to corticosteroid therapy. An autopsy 15 years after the onset of symptoms revealed hypertrophic radiculopathy and peripheral neuropathy due to CIDP with no evidence of neurofibromatosis. This case illustrates how the hypertrophic neuropathy accompanying CIDP can be mistaken for neurofibromatosis.- - - - - - - - - - ranking = 33.367149291569keywords = chronic inflammatory demyelinating, inflammatory demyelinating, demyelinating (Clic here for more details about this article) |
4/4. Corticospinal tract MRI hyperintensity in X-linked charcot-marie-tooth disease.In X-linked hereditary demyelinating neuropathies (CMTX), caused by mutations in Connexin 32, mild subclinical CNS involvement is not unusual. We present a young male patient suffering from genetically proven CMTX who presented with permanent bilateral corticospinal tract hyperintensities in cranial MRI -- a finding previously described to be characteristic for amyotrophic lateral sclerosis. MRI seems to be able to visualize corticospinal tract abnormalities, even if subclinical, in CMTX.- - - - - - - - - - ranking = 0.2keywords = demyelinating (Clic here for more details about this article) |
