Elevated RDW is associated with migraine requiring further efforts to clarify the actual underlying pathophysiology.

The present findings demonstrated that CTS may be triggered by vitamin D deficiency, and that the severity of CTS was correlated with vitamin D levels in the deficiency group. Additionally, there was a correlation between weight gain and neuropathic pain intensity in CTS patients with vitamin D deficiency. The present findings indicate that vitamin D levels should be assessed in CTS patients.

BackgroundThe importance of the removal of spinal implants is known in the presence of infection. However, the benefits and/or risks of the removal of spinal implant for the management of back pain are not clear.MethodsIn this retrospective study, we aimed to evaluate the beneficial effects of the removal of spinal implants for back pain. Study included 25 patients with thoracolumbar instrumentation.ResultsSeventeen (68%) of them were male. Indications for spinal instrumentation were vertebra fracture (n = 9), iatrogenic instability due to multiple segment laminectomy (n = 12), and instrumentation after recurrent disk herniations (n = 4). Mean visual analog score (VAS) before the removal was 8.08. Mean VAS was 3.36 after the removal. Spinal instruments were removed after the observance of the presence of fusion. All patients were prescribed analgesics and muscle relaxants for 3 weeks before removal. Back pain did not decrease in five (20%) patients in total. Four of them had been instrumented due to recurrent lumbar disk herniation. None of the patients reported the complete relief of pain.ConclusionIn conclusion, patients should be cautioned that their back pain might not decrease after a successful removal of their instruments.
