A host of influences contribute to cognitive and behavioral changes following deep brain stimulation. The location of the active cathode is likely an important variable but it has received little attention. ⋯ Location of the active contact is related to nonmotor outcomes, even in electrodes that are adequately placed. This is relevant to clinical care as there appears to be a trade-off between mood and fluency abilities that should be considered during surgical planning according to preoperative patient characteristics.

Atypical pituitary adenomas (APAs) are a subset of pituitary adenomas (PAs) characterized by the 2004 World Health Organization (WHO) guidelines to have higher risk histopathological features than typical PAs. In July 2017, the WHO published an update to their classification of pituitary tumors and abandoned the APA terminology. ⋯ Based on diagnostic variability and lack of association with clinical outcomes, refinement of criteria for APA was necessary. The WHO update eliminates the ambiguity in APA diagnosis in favor of criteria that emphasize clinical behavior (invasion, recurrence, and resistance to treatment) and molecular markers. Our review supports abandonment of the previous APA designation due to limited prognostic utility.

Primary drivers (PDs) of adult cervical deformity (ACD) have not been described in relation to pre- and early postoperative alignment or degree of correction. ⋯ Characterizing ACD patients by PD type reveals differences in pre- and postoperative alignment. Evaluating surgical alignment outcomes based on PD inclusion is important in understanding alignment goals for ACD correction.

Assuring clinical competence throughout the career of a neurosurgeon is of paramount importance for patient safety. We present the first comprehensive survey of all neurosurgeons board certified through the American Board of Neurological Surgery (ABNS) to evaluate perceptions of Maintenance of Certification (MOC). We administered a validated, online, confidential survey to 4899 neurosurgeons (2435 ABNS diplomates participating in MOC, 1440 diplomates certified prior to 1999 [time-unlimited certificates], and 1024 retired diplomates). ⋯ A plurality of respondents (44%) do not feel that the MOC process as currently structured provides them with value. There were no differences between those who were "grandfathered" and those who actively participate in MOC and no differences between those in private practice versus those in academics. The ABNS is cognizant of diplomate concerns and is actively developing new MOC paradigms to ensure that the process achieves both the goals of meeting the public interest and assuring that the quality of American neurosurgery remains exemplary.
