Pre-incisional Localization: An Overlooked Contribution by Ralph Bingham Cloward.
Preincisional localization has become ubiquitous within spinal neurosurgery and has served as the foundation for modern minimally invasive surgery techniques. Dr. ⋯ In his landmark 1958 article on what is now known as anterior cervical diskectomy and fusion, Cloward commented on a case of wrong-level surgery that motivated him to implement a standardized technique for spinal level localization with the patient under anesthesia in the operating room before skin incision. We trace the origins of the use of preincisional radiographs to localize the pathologic level at the time of diskectomy and highlight this original contribution by Cloward.

Mesoamerica is culturally rich in diverse aspects, such as nature, sociology, and archeology. Several neurosurgical techniques were described during the Pre-Hispanic era. In Mexico, various cultures, such as the Aztec, Mixtec, Zapotec, Mayan, Tlatilcan, and Tarahumara, developed surgical procedures using different tools to perform cranial and probably brain interventions. ⋯ More than 40 skulls have been rescued and studied in this region. In addition to written medical sources, archeological vestiges allow a more profound comprehension of Pre-Columbian brain surgery. The purpose of this study is to present the existing evidence of cranial surgery in Pre-Hispanic Mexican civilizations and their worldwide counterparts, procedures that have contributed to the global neurosurgical armamentarium, and have significantly impacted the medical practice's evolution.

Second Cancer affecting the Central Nervous System: Systematic Literature Review Exploring the Link between Malignant Melanoma and Glioblastoma.
Glioblastoma (GBM) is a malignant primary brain cancer, among the most devastating and lethal diseases of the central nervous system. Similarly, malignant melanoma (MM) is responsible for most skin cancer-related deaths. A link between those 2 aggressive cancers has not yet been established. We present here a systematic review of the literature and an exemplificative case. ⋯ The evidence reported in the literature, as well as our surgical vignette, support a likely link between the pathogenesis of GBM and MM.

The use of radiotherapy (RT) for the treatment of vestibulocochlear schwannomas is standard in patients with type 2 neurofibromatosis (NF2). In the general population, fractionated RT (FRT) can achieve good results compared to single-dose radiosurgery (SRS). We aimed to assess whether this is true for NF2 patients as well. ⋯ In the NF2 population, FRT may yield worse control rates than SRS. Whenever possible, it is preferable to not fractionate treatment for these patients. Nevertheless, the FRT results were still good. More and larger prospective trials are warranted.

The NeVa stent retriever is a newly designed mechanical thrombectomy device for the treatment of acute ischemic stroke caused by large vessel occlusion. We investigate the procedural characteristics and patients' clinical outcomes at discharge and at 90 days of follow-up. ⋯ Endovascular stroke management with use of the NeVa-Vesalio stent retriever may be associated with a 90-day functional mRS score in nearly 40% of treated patients.
