Amazonas is the largest state in Brazil, covering an area of 1,559,159.148 km2 and primarily occupied by the Amazon rainforest. Fluvial and aerial transport are the primary means of transportation. Studying the epidemiologic profile of patients transported by neurologic emergencies is essential because there is only 1 referral center hospital serving approximately 4 million inhabitants in Amazonas. ⋯ Air transportation for neurologic evaluation is essential in Amazonas. However, most patients did not require neurosurgical intervention, indicating that investments in medical infrastructures, such as computed tomography scanners and telemedicine, may optimize health costs.

To explore the application value of preoperative multimodal image fusion technique in microvascular decompression (MVD) surgery via the suboccipital retrosigmoid approach. ⋯ Preoperative multimodal image fusion technology can provide adequate preoperative assessment for patients and assistance in designing surgical approaches, which is an important guideline for MVD surgery via the suboccipital retrosigmoid approach for primary TN and facial muscle spasm.

Flexion-extension magnetic resonance imaging (MRI) has potential to identify cervical pathology not detectable on conventional static MRI. Our study evaluated standard quantitative and novel subjective grading scales for assessing the severity of cervical spondylotic myelopathy in dynamic sagittal MRI as well as in static axial and sagittal images. ⋯ Flexion-extension MRI demonstrated significant changes not available from conventional MRI. Subjective scales for assessing degenerative changes were significantly more severe at levels with operative cervical spondylotic myelopathy. The utility of these scales for planning surgical intervention at specific and adjacent levels is currently under investigation.

Surgical intervention for chronic subdural hematoma (CSDH) in the extremely aged population remains a difficult challenge. This study aims to investigate the clinical characteristics and surgical outcomes after twist drill craniotomy (TDC) of CSDH in super-elderly (≥80 years) patients. ⋯ Advanced age per se does not seem to be a contraindication for the operative intervention of CSDH. Surgical treatment using the TDC procedure can still provide considerable benefits for super-elderly patients with CSDH.

Following sport-related concussion (SRC), early studies have demonstrated racial differences in time to clinical recovery; however, these differences have not been fully explained. We sought to further explore these associations by considering possible mediating/moderating factors. ⋯ Overall, Black athletes initially presented with fewer concussion symptoms than White athletes, despite no difference in time to clinic. Black athletes achieved earlier clinical recovery following SRC, a difference explained by differences in initial symptom burden and self-reported concussion history. These crucial differences may stem from cultural/psychologic/organic factors.
