Nervus intermedius neuralgia is an extremely rare craniofacial neuralgia characterized by paroxysmal episodes of pain located deep in the ear, typically triggered by sensory or mechanical stimuli at the wall of the auditory canal without underlying pathology. Pain is sometimes associated with disorders of lacrimation, salivation, and taste. ⋯ It is important to keep in mind the possibility of nervus intermedius neuralgia in patients who present with intermittent episodes of pain located deep in the ear. Furthermore, 3D-MRC/MRA fusion imaging is useful for decision-making in surgery. Microvascular decompression was highly effective in our case. Based on radiological findings, microvascular decompression should be considered a viable treatment option.

Incisional negative pressure wound therapy (NPWT) is used in many surgical specialties to prevent postoperative dehiscence and surgical site infections (SSIs). However, little is known about the role of incisional NPWT in spine fusion surgery. Therefore, we sought to report a single surgeon's experience using incisional NPWT and describe its effects on dehiscence and SSIs after instrumented spine surgery. ⋯ NPWT decreases dehiscence and SSIs in patients undergoing lumbar fusion through an anterior approach. When preferentially used in patients at high risk for postoperative wound complications, NPWT prevents increased rates of dehiscence and SSI.

Although previous studies have reported the expression of JAK1, STAT3, and phosphorylated STAT3 in hypertrophied ligamentum flavum (LF), the role of the Janus kinase-signal transducer and activator of transcription (JAK/STAT) signaling pathway in hypertrophied LF has not been fully elucidated. The aim of this study was to identify the important JAK/STAT gene expression patterns of the 3 main receptors involved in this pathway: interferon (IFN)-γ receptor (IFN-γR), IFN-α receptor (IFNAR), and interleukin (IL)-6 receptor (IL-6R). ⋯ Our data suggest that IFNAR- and IL-6R-dependent JAK/STAT signaling pathways may be significant targets in drug development strategies for the treatment of LF hypertrophy.

Comparative Study
Comparison of the CRASH-predicted and real outcome of TBI in a retrospective analysis of 417 patients.
The aim of this retrospective study was to externally validate the CRASH (Corticosteroid Randomisation After Significant Head Injury) clinical calculator as a prognostic tool. Mortality at 14 days and an unfavorable outcome (i.e., Glasgow Outcome Scale score <4) after 6 months were the primary endpoints. ⋯ The CRASH calculator is a good predictor of outcome in traumatic brain injury at 14 days and 6 months with high sensitivity and specificity. It does not replace clinical judgment of the physician treating the patient in the emergency department, but it constitutes a useful additional tool.

Even for the most experienced neurosurgeons, foramen magnum meningiomas represent a surgical challenge owing to their delicate position surrounded by the brainstem, lower cranial nerves, and vertebral arteries. The treatment goal is gross total resection, but choosing the most appropriate approach is crucial. Basically, 3 surgical approaches are commonly used: posterolateral approach (far-lateral), anterolateral approach (extreme-lateral), and posterior midline approach. ⋯ Care must be taken with tumors with a more lateral and caudal extension (below the tip of the odontoid process), when a far lateral approach may be the best approach. In this surgical Video 1, we present the surgical details with a stepwise narrative of the EEA for ventrolateral foramen magnum meningiomas through an illustrative case of a 48-year-old woman. Institutional informed consent was obtained for surgery and publication of this video.
