Although studies have evaluated the economic burden to medical students desiring a neurosurgery residency broadly, a detailed breakdown of costs has not been reported. Given that the Association of American Medical Colleges and Society of Neurological Surgeons have recommended neurosurgery residency programs for the 2021 residency application cycle cancel away rotations and in-person interviews, our objective was to evaluate cost savings to medical students applying during this time and the implications. ⋯ In the COVID-19 era, neurosurgery residency applicants could save >$10,000 through the use of virtual interviews and lack of away rotations. There are potential geographic trends; however, further evaluation should be performed.

Neural tube defects are among the most frequent congenital abnormalities of the central nervous system. Progression of neural tube deficits is affected by hereditary predilection and environmental determinants. Pethidine (meperidine) is a fast and powerful opioid analgesic in U.S. Food and Drug Administration category C. There are reports about developmental anomalies due to this medication. The aim of this study was to investigate the effects of different doses of pethidine hydrochloride on neural tube development in a chick embryo model resembling the first month of vertebral growth in mammals. ⋯ We demonstrated that pethidine hydrochloride affects neuronal development in chicken embryos. The teratogenic mechanism of pethidine hydrochloride is unclear; therefore, further investigation is required.

While benefits of neurosurgical intraoperative ultrasound (IOUS) are reported frequently, this method still has some significant pitfalls, which are described less often. However, sufficient knowledge on dealing with IOUS drawbacks, particularly various image artifacts, is important for successful surgery. We report a case of failed IOUS-guided pediatric cerebellar pilocytic astrocytoma resection, incorrectly evaluated as gross total resection according to IOUS. ⋯ Successful IOUS-guided reoperation using new IOUS technology and appropriate ultrasound imaging technique are described. The most probable reasons for initial resection failure and crucial points of reoperation, predominantly dealing with IOUS artifacts, are discussed. Neurosurgeons should be aware of IOUS limitations and have sufficient knowledge about how to overcome them before adopting routine use of this intraoperative imaging modality.

Comparative Study
A Comparison of Surgical Outcomes of Microdiscectomy Procedures by Patient Admission Status: Short Title: Patient Admission Status in Microdiscectomy Procedures.
We sought to compare the cost and in-hospital outcomes following lumbar microdiskectomy procedures by admission type. ⋯ Patients admitted as transfers and from the ED had significantly increased hospitalization lengths of stay and direct costs compared with electively admitted patients.

Chronic subdural hematoma is frequently seen within the elderly population and neurosurgeons are confronted with patients older than 80 years presenting with symptomatic chronic subdural hematoma. However, data on surgical outcome are scarce. The aim of this study is to analyze the mortality and outcome after burr-hole drainage in patients older than 80 years. ⋯ In patients older than 80 years undergoing burr-hole drainage for chronic subdural hematoma, age was not directly correlated with higher recurrence, postoperative bleeding, or mortality rates.
