Stigma is defined as a social process resulting in labeling, stereotyping, and separation that cause status loss, disapproval, rejection, exclusion, and discrimination of the labeled individuals. Stigma can be experienced by individuals or groups, can be real or perceived, and can include a wide array of characteristics (e.g., race/ethnicity, gender, and health conditions). It is well documented that stigma for health conditions is a barrier to treatment and leads to worse outcomes for vulnerable people. ⋯ This review provides an overview of stigma and its application in a neurosurgical setting, including diagnoses treated by neurosurgeons as well as diagnoses with impact on neurosurgical outcomes. Examples of stigmatizing diagnoses of relevance to neurosurgical practice include epilepsy, pain, smoking, obesity, and substance use disorder. This information is useful for the practicing neurosurgeon to understand the origins and higher-order effects of societal perceptions surrounding certain diagnoses, and the subsequent effects on health that those perceptions can create on a systemic level.

With the evolution of endoscopic instruments and techniques, full-endoscopic spine surgery has attracted more attention worldwide in recent years. At the initial stage, surgeons conducted endoscopic lumbar discectomy using the transforaminal approach. Next, interlaminar endoscopic lumbar discectomy was developed to treat a herniation disc at the L5-S1 level. ⋯ However, the steep learning curve of endoscopic procedures has remained challenging. The use of interlaminar endoscopic lumbar discectomy entails many essential skills to manage the different anatomical structures of the spine. From the perspective of successful and safe interlaminar endoscopic lumbar discectomy, we have discussed the technical considerations for endoscopic procedures.

Microvascular decompression with transposition of the involved vessels provides good surgical outcomes in cases of complex and recurrent neurovascular compression syndromes. We conducted a literature review to illustrate the variations in the surgical techniques used for transposition and to provide a practical decision-making scheme for transposition of the involved vessel. ⋯ Transposition of the involved vessel is a valuable procedure for microvascular decompression of the posterior fossa cranial nerves. Anchoring the vessel to the adjacent anatomical wall ensures secure transposition. The proposed algorithm provides a systemic scheme to identify the optimal anatomical wall, and to determine the technique and material that can be used to anchor involved vessel. This scheme is an efficient method to inform the intraoperative decision-making process.

The ability of ultrasonography to safely penetrate deeply into the brain has made it an attractive technology for neurological applications for almost 1 century. Having recognized that converging ultrasound waves could deliver high levels of energy to a target and spare the overlying and surrounding brain, early applications used craniotomies to allow transducers to contact the brain or dural surface. The development of transducer arrays that could permit the transit of sufficient numbers of ultrasound waves to deliver high energies to a target, even with the loss of energy from the skull, has now resulted in clinical systems that can permit noninvasive focused ultrasound procedures that leave the skull intact. ⋯ The major clinical use of this technology, at present, has been limited to treatment of refractory essential tremor and parkinsonian tremor, although the first study of this approach had targeted sensory thalamus for refractory pain, and new targets and disease indications are under study. Finally, focused ultrasonography can also be used at a lower frequency and energy level when combined with intravenous microbubbles to create cavitations, which will open the blood-brain barrier rather than ablate tissue. In the present review, we have discussed the historical and scientific foundations and current clinical applications of magnetic resonance-guided focused ultrasonography and the genesis and background that led to the use of this technique for focal blood-brain barrier disruption.

To perform an ecological study to analyze the geospatial distribution of neurosurgeons ≥60 years old and compare these data with the spread of 2019 novel coronavirus disease (COVID-19) across the United States. ⋯ Regional COVID-19 hotspots may coincide with areas where a substantial proportion of the neurosurgical workforce is ≥60 years old. Continuous evaluation and adjustment of local and national clinical practice guidelines are warranted throughout the pandemic era.
