Acute on chronic cervical myelopathy causing cervical segmental myoclonus in a high-level wheelchair athlete: a case report.

INTRODUCTION: This is a 20-year-old wheelchair athlete with history of caudal regression syndrome and cervical canal stenosis who developed spinal segmental myoclonus following routine intubation for an elective procedure. CASE PRESENTATION: This patient is a 20-year-old man with history of caudal regression syndrome and chronic cervical stenosis. He is a high-level wheelchair racer and paralympic hopeful. This patient initially presented 18 months prior with shoulder abduction weakness. He was found to have cervical stenosis at C4, C5 on MRI. Neurosurgical treatment was not needed at that time as symptoms resolved. On this encounter, he presented for an elective urologic surgical procedure. Glidescope intubation was performed with notable cervical extension. In the Post Anesthesia Care Unit, the patient began experiencing twitching movements in his pectoral muscles bilaterally as well as left deltoid and biceps. His findings were consistent with myoclonus due to his cervical myelopathy. He was initially started on levetiracetam, but experienced dizziness. His symptoms were finally controlled with clonazepam. Neurosurgery performed cord decompression and fusion with resolution of his symptoms. DISCUSSION: There are few cases of myoclonus secondary to myelopathy documented in literature. The current recommended treatments, levetiracetam and/or benzodiazepines, were successful in managing the myoclonus in this patient. However, cord decompression is necessary to avoid progression of myelopathic symptoms. In conclusion, myoclonus can be a presenting symptom of myelopathy and warrants further investigation, especially in patients with known spinal cord or vertebral pathology.

An observational report of swallowing outcomes following corpus callosotomy.

AIM: Determine swallowing outcomes following corpus callosotomy (CC) surgery. METHODS: Retrospective chart review of patients undergoing CC between July 2016 and November 2018 at a large, urban children's hospital. RESULTS: Of the 18 patients without prior history of dysphagia who underwent CC, 15 received speech pathology consults for bedside swallowing evaluation (BSE). Four patients were referred for a videofluroscopic swallow study (VFSS), and 3 showed no signs of difficulty and were advanced to regular diets with thin liquids. One patient demonstrated swallowing difficulties during the VFSS and was placed on a regular diet with nectar thick liquids. Following a repeat swallow study 17 days post-surgery, the patient was advanced to thin liquids. INTERPRETATION: Postoperative dysphagia following CC is an uncommon and transient complication. Patients undergoing CC should have their swallowing evaluated prior to advancing their postoperative diet but are likely to return to normal diet and thin liquids by discharge.

Dual spinal cord injury: a case of acute traumatic T9 AIS A spinal cord injury complicated by transverse myelitis.

INTRODUCTION: While the general principles of treatment of TM are agreed upon, the rarity of the disease has made determining its clinical course and etiology quite difficult. This report aims to inform these debates by demonstrating the susceptibility of at least one individual to transverse myelitis following an acute SCI. CASE PRESENTATION: This case report follows the clinical course of a 17 year old. Caucasian female that contracted transverse myelitis (TM) following an acute traumatic spinal cord injury. This patient originally presented as a T9 AIS A traumatic SCI, and was then re-graded as C6 AIS A SCI following diagnosis of TM. She was later seen in clinic for 6-month follow-up and displayed post-trauma baseline scores for both strength and sensation, indicating nearly complete recovery. DISCUSSION: In addition, this report demonstrates the importance of adequate clinical management of TM in practical terms of patient performance on clinical exams. This report also adds to the existing body of evidence suggesting early intervention is associated with better functional outcomes.
