At least 25% of patients with idiopathic generalized epilepsy do not obtain adequate seizure control with medication. This report describes the first use of responsive neurostimulation (RNS), bilaterally targeting the centromedian/ventrolateral (CM/VL) region in a patient with drug-refractory Jeavons syndrome (eyelid myoclonia with absences). ⋯ RNS decreased daily absence seizures from a mean of 60 to ≤10 and maintained the patient's level of consciousness during the occurring episodes. This therapy should be evaluated further for its potential to treat patients with pharmaco-refractory generalized epilepsy.

There are radiographic and clinical outcome differences between patients with deep and lobar intracerebral hemorrhage (ICH) locations. Pilot studies suggest that there may be functional coagulation differences between these locations detectable using whole blood coagulation testing. ⋯ We identified longer clot formation times, suggesting relative coagulopathy in deep compared to lobar ICH confirming results from prior work. Further work is required to elucidate mechanisms for these differences and whether ICH location should be considered in future coagulopathy treatment paradigms for ICH.

Diabetes insipidus (DI) is a recognized transient or permanent complication following transsphenoidal surgery (TSS) for pituitary tumors. ⋯ Although transient DI is a relatively common complication of endoscopic and microscopic TSS, permanent DI is much less frequent. The underlying pathology is an important predictor of both occurrence and permanency of postoperative DI.

Meningioma growth rates are highly variable, even within benign subgroups, with some remaining stable, whereas others grow rapidly. ⋯ The proposed models might enable more accurate prediction of time to meningioma recurrence and thus determine optimal postoperative management. Moreover, combining this model with current knowledge of molecular processes underpinning recurrence could permit the identification of distinct meningioma subtypes and enable better-targeted therapies.

Tribute to Milton D. Heifetz (1921-2015): The Man Behind the Heifetz Aneurysm Clip.
Milton Dave Heifetz (1921-2013) was a pioneer American neurosurgeon who spent the majority of his career at Cedars-Sinai Hospital in California. Heifetz greatly influenced the field of neurosurgery as an innovator, leader, and academic neurosurgeon. His redesign of the aneurysm clip addressed the long-standing issue of a fatiguing spring. ⋯ In 1975, he published The Right to Die: A Neurosurgeon Speaks of Death With Candor, a book which played a major role in our modern-day advanced directives. Throughout his life, Heifetz was an inspirational individual who consistently worked towards solutions to surgical and ethical problems. We present a historical vignette on his life, career, and contributions to neurosurgery.
