Review Case Reports
Primary NK/T-cell lymphoma of the cauda equina: a case report and literature review.
A case report with a review of the literature. ⋯ Although primary lymphoma of the cauda equina is extremely rare, the prognosis of this condition is thought to be poor. Early definitive diagnosis with examination of the cerebrospinal fluid followed by combined treatment with radiotherapy and high-dose methotrexate should be considered.

Multicenter, retrospective chart analysis was performed using data housed in the trauma registries of 2 independent American College of Surgeons verified, Level I Trauma centers. The trauma registries were queried for all cases of penetrating cervical trauma. Abstracted data included age, sex, race, mechanism of injury, Glasgow Coma Scale (GCS) level on arrival, neurologic findings on arrival, zone of injury, associated injuries, imaging studies and results, operations performed, neurologic sequelae, disposition from the hospital and the presence or absence of neurologic injury, cervical spine fracture, and cervical spine immobilization. ⋯ Cervical spine immobilization does not appear to prevent progression of neurologic injury in cases of penetrating cervical trauma. Comorbid penetrating injuries may be negatively impacted by prehospital cervical spine immobilization.

Case Report. ⋯ Neoplasm and infection were excluded. Careful reassessment alerted to the diagnosis of undifferentiated spondyloarthropathy. Solid arthrodesis and pain relief could be obtained by surgery together with medical control of the disease.

Review Case Reports
False-negative transcranial motor-evoked potentials during scoliosis surgery causing paralysis: a case report with literature review.
Case report. ⋯ From our experience of false-negative MEPs, we conclude that unwanted events with use of MEP in scoliosis or other spinal surgeries. We propose further prospective research on animals to solve this issue.

A biomechanical study using human cadaveric thoracolumbar spinal columns. ⋯ New vertebral fractures occurred at the vertebra adjacent to augmented vertebrae in the P group and in the augmented vertebrae in the C group. The difference in the fractured site may be because of the difference in strength between the 2 bone filler materials. Therefore, the strength of bone filler materials is considered a risk factor in developing adjacent vertebral body fractures after VP.
