Article Synopsis
  • In partial onset epilepsy, seizures start in specific brain areas and can become resistant to medication, making neurosurgery a key treatment option that risks neurological deficits.
  • A study on mice with focal neocortical epilepsy applied precise cuts using femtosecond laser pulses around the seizure focus, significantly reducing seizure frequency by 87% and limiting the spread of seizures.
  • The surgical cuts led to minimal collateral damage and did not impair motor skills in reaching tasks, indicating potential for this method as an effective neurosurgical strategy for treating refractory focal epilepsy.

Pediatric traumatic brain injury (pTBI) is a major risk factor associated with adulthood incarceration. Most research into the link between pTBI and adulthood incarceration has focused on incarcerated males, who comprise the vast majority of incarcerated adults, particularly in industrialized nations. In this review, we sought to identify sex-related differences in the incidence and pathophysiology of pTBI and subsequent risk of adulthood incarceration.

Objective: Virtual mentorship and research programs are becoming increasingly popular to facilitate education and career development for students and residents. We review virtual research initiatives for early trainees in neurosurgery and describe our effort to expand access to resources and shared objective mentorship (SOM) via the novel Neurosurgery Education and Research Virtual Group (NERVE).

Methods: A systematic review of neurosurgical programming delivered via a virtual platform was conducted using PubMed, Embase, and Scopus databases.

Objective: Neurosurgery has a high barrier of educational access for medical students. The Medical Student Neurosurgery Training Center (MSNTC) is a novel online learning platform that provides on-site and virtual training opportunities and resources that aim to increase student access to neurosurgical education. The objective of this article was to describe student-reported utility of Medical Student Neurosurgery Training Center educational resources.

Objective: Interest groups for medical students (MSs) facilitate interest and engagement in neurosurgery. Students without interest groups are at a disadvantage as a result of greater barriers to exposure. We aimed to compare the usefulness of a virtual neurosurgery training camp for MSs with and without interest groups.

Objective: Addressing equitable opportunities for medical student (MS) education is important for minimizing disparities in neurosurgical care. However, international MSs, particularly from low- and middle-middle income countries (LMICs) may lack access to educational opportunities compared with their contemporaries in high-income countries. We compare the usefulness of virtual neurosurgery training camps (VNTC) between U.

Objective: Distance learning has become increasingly important to expand access to neurosurgical spine education. However, emerging online spine education initiatives have largely focused on residents, fellows, and surgeons in practice. We aimed to assess the utility of online neurosurgical spine education for medical students regarding career interests, knowledge, and technical skills.

Objective: Virtual learning has made neurosurgery education more available to medical students (MSs) of all stages than ever before. We aimed to evaluate the impact of on-site learning in order to assess whether a return to this method of teaching, when safe, is warranted for MSs of all years.

Methods: Registrants of the 2019 MS Neurosurgery Training Camps were sent precourse and postcourse surveys to assess changes in self-assessed confidence in concrete neurosurgical skills.

Introduction: There is a growing need for collaborative and broad-scale medical student neurosurgery educational initiatives. Here, we propose a comprehensive methodology and structure for hosting both in-person and virtual learning opportunities for early trainees interested in clinical neurosciences.

Methods: We conducted an internal review of educational courses hosted by Medical Student Neurosurgery Training Center from 2017 to 2022.

Neurosurgeons have a rich history of involvement in medical student education. We review the scope of related published works with the goal of highlighting recently increased efforts to innovate in neurosurgical education and discuss where future efforts must go. A scoping review was performed after comprehensive search of PubMed MEDLINE and Embase databases.

Objective: There remains a gap in the literature analyzing how categorical variables may affect the highly competitive neurosurgery residency application process for MD Seniors in the United States. We aimed to improve understanding of the impact of medical school prestige and geographic location on candidacy for neurosurgery residency.

Methods: Schools were stratified into high and low prestige cohorts based on the U.

Objective: To examine the perceived effectiveness of the virtual neurosurgery training camps (VNTC) among medical students with (HP) and without (NHP) home neurosurgery residency programs.

Methods: A survey assessing demographics, baseline interests, and ratings of usefulness and interest of programming was sent to attendees after the VNTC. Ratings were quantified on modified 7-point Likert scales.

Objectives: Intracranial arachnoid cysts are commonly characterized as congenital. Evidence to support a congenital origin is scant and documented evolution during infancy also calls into question the genesis of these lesions. To improve our understanding of the natural history and the clinical significance of arachnoid cysts on prenatal ultrasound, we conducted a study to describe the fate of these cysts after initial diagnosis.

Objective: The factors that attract and concern medical students about a career in neurosurgery have never been clearly characterized or delineated in a large nationwide cohort of medical students intending to pursue a career in neurosurgery. The objective of the present study was to characterize the factors that influence medical student interest in neurosurgery and assess the effects of a formal neurosurgery training course on participants' perceptions of a career in neurosurgery.

Methods: Before the Medical Student Neurosurgery Training Camp for subinternship preparation, registered students were surveyed about their interest level in neurosurgery, factors that attracted or concerned them about a career in neurosurgery, attendance at a national neurosurgery conference or course, formal clinical neurosurgery exposure in medical school, and whether they had a resident or attending mentor in neurosurgery.

Objective: Historically, medical student education in neurological surgery has generally limited student involvement to assisting in research projects with minimal formal clinical exposure before starting sub-internships and application for the neurosurgery match. Consequently, students have generally had little opportunity to acquire exposure to clinical neurosurgery and attain minimal proficiency. A medical student training camp was created to improve the preparation of medical students for the involvement in neurological surgery activities and sub-internships.

Objective: Postoperative surgical site infections (SSIs) in neurosurgical patients carry a significant risk of increased morbidity and mortality. With SSIs accounting for approximately 20% of nosocomial infections and costing approximately $1.6 billion USD annually, there is a need for additional prophylaxis to improve current standards of care.

Recent evidence shows that seizures propagate primarily through supragranular cortical layers. To selectively modify these circuits, we developed a new technique using tightly focused, femtosecond infrared laser pulses to make as small as ~100 µm-wide subsurface cortical incisions surrounding an epileptic focus. We use this "laser scalpel" to produce subsurface cortical incisions selectively to supragranular layers surrounding an epileptic focus in an acute rodent seizure model.

Background: The ideal suturing technique for microvascular anastomosis for neurosurgical bypass procedures remains a point of debate. Simple interrupted sutures are thought to possess higher long-term patency but require more time to place as compared to running sutures.

Objective: To optimize the efficiency of microvascular anastomosis and limit brain ischemia time.

Surgical-site infections (SSIs) account for 20% of all healthcare-associated infections, are the most common nosocomial infection among surgical patients, and are a focus of quality improvement initiatives. Despite implementation of many quality care measures (e.g.
