Review Case Reports
False negative and positive motor evoked potentials in one patient: is single motor evoked potential monitoring reliable method? A case report and literature review.
A case report and literature review. ⋯ From our experience of false negative and positive MEP in 1 patient, it is concluded that undesirable events can occur with use of MEP in scoliosis or other spinal surgery. Therefore, we warn the surgeons too heavily rely on the MEP monitoring, and propose a further prospective study as well as use of alternative method that can improve the reliability of single MEP.

Review Case Reports
Subarachnoid-pleural fistula treated with noninvasive positive pressure ventilation: a two-case report and literature review.
A report on 2 cases of subarachnoid pleural fistula (SAPF) treated with noninvasive positive pressure ventilation (NPPV). ⋯ SAPF is often resistant to conservative therapies and has been treated in an invasive manner. NPPV should be considered as an alternative before such interventions because it is effective, noninvasive, and safe.

Randomized Controlled Trial Comparative Study
Low back pain in primary care: costs of care and prediction of future health care utilization.
Cost of illness study alongside a randomized controlled trial. ⋯ Interventions designed to reduce high health care costs for LBP should focus on patients with severe LBP and depressive comorbidity. Our results add to the economic understanding of LBP care and may give guidance for future actions on health care improvement and cost reduction.

Review Case Reports
Absent inferior vena cava resulting in exercise-induced epidural venous plexus congestion and lower extremity numbness: a case report and review of the literature.
Case report and clinical discussion. ⋯ This case demonstrates the breadth of anatomic and physiologic understanding a clinician must draw on when approaching patients with nerve root compression symptoms. It is also pertinent to consider performing a hypercoagulable work-up in patients with vascular deformations, as this may prevent future thrombosis.

Comparative Study
Prospective ten-year follow-up study comparing patients with whiplash-associated disorders and asymptomatic subjects using magnetic resonance imaging.
A prospective 10-year follow-up study of patients with whiplash-associated disorders (WAD) and asymptomatic volunteers. ⋯ The results of this study suggest that, although some WAD patients are more likely to suffer from long-lasting neck pain, MRI findings cannot explain the symptoms.
