High school (HS) sport-related concussions (SRCs) remain a public health concern in the United States. ⋯ Headache was the most commonly reported symptom. Notable group differences in the prevalence of amnesia, loss of consciousness, and SRT may be associated with more severe SRCs, warranting further attention.

Apraxia of speech is a disorder of articulatory coordination and planning in speech sound production. Its diagnosis is based on deficits in articulation, prosody, and fluency. It is often described concurrent with aphasia or dysarthria, while pure apraxia of speech is a rare entity. ⋯ The case reported here details a rare clinical entity, pure apraxia of speech resulting from resection of posterior middle frontal gyrus. While not a classical language area, emerging literature supports the role of this area in the production of fluent speech, and has implications for surgical planning and the general neurobiology of language.

Reflections on the History of Nerve Repair - Sir Sydney Sunderland's Final Presentation to the Neurosurgical Society of Australasia.
Sir Sydney Sunderland (1910-1993) was an eminent physician and anatomist who identified the fascicular structure of nerves, and developed the eponymous 5-tiered classification of nerve injuries. Not long before his death, he presented a keynote address to the Annual Scientific Meeting of the Neurosurgical Society of Australasia. ⋯ Sir Sydney discussed nerve injuries sustained during World War I, with the deleterious effects of infection, and following the many nerve injuries sustained during World War II, he discussed his own discoveries of internal topography of nerve fascicles, and the anatomical substrate of nerve fascicles that limit surgery for nerve repair, nerve grafts, and the basic science of spinal cord repair. This paper presents a transcript of Sunderland's presentation and includes many of his original images used to illustrate this tour de force of nerve repair.

No guidelines have been published regarding stereotactic radiosurgery (SRS) in the management of Spetzler-Martin grade I and II arteriovenous malformations (AVMs). ⋯ The literature regarding SRS for grade I-II AVM is low quality, limiting interpretation. Cautiously, we observed that SRS appears to be a safe, effective treatment for grade I-II AVM and may be considered a front-line treatment, particularly for lesions in deep or eloquent locations. Preceding publications may be influenced by selection bias, with favorable AVMs undergoing resection, whereas those at increased risk of complications and nonobliteration are disproportionately referred for SRS.
