Spinal myoclonus in subacute combined degeneration caused by nitrous oxide intoxication.
نویسندگان
چکیده
A 26-year-old patient developed ascending weakness and paresthesias. Megaloblastic anemia and mildly reduced serum vitamin B12 (B12) concentration were noted. Myoclonus-like muscular contractions appeared over four extremities and in the trunk. She admitted inhaling nitrous oxide (N2O) as a euphoriant repeatedly at party. Following parenteral B12 administration, her neurological deficit promptly resolved. This case demonstrated the abuse of N2OI is an important cause of subacute combined degeneration (SCD) of the spinal cord. To our knowledge, this is the first report of involuntary movements in a patient with N2O intoxication. Although the mechanism remains unknown, involuntary movements similar to myoclonus should be considered as one of the extraordinary neurological manifestations of N2O intoxication.

Subacute combined degeneration (SCD) is a rare neurological complication of vitamin B12 deficiency, characterized by demyelination of the dorsal and lateral spinal cord. Herein, we describe three cases, who presented with SCD, one related to reduced intake of vitamin B12 because of a vegetarian diet and two related to nitrous oxide exposure during surgery. MR images of our patients revealed sym...

Subacute combined degeneration ( SCD) due to vitamin B12 deficiency is common in North of Europe but sometimes it is seen in Iran. It can develop before the symptoms of anemia is obvious, with myelin injury and then axon and even neuron destruction in spinal cord, brain, optic and peripheral nerves. In this study two cases are reported; in the first patient, this disease in manifested by vitami...

Nitrous oxide is increasingly being used as a recreational drug. Prolonged use of nitrous oxide can have disabling neurological sequelae due to functional inactivation of vitamin B₁₂. We present three cases illustrating the neurological complications of using nitrous oxide. Two of these patients received nitrous oxide as a consequence of repeated hospital attendance and the third via 'Whippit' ...
