Transcranial MR-Guided Histotripsy System.

Histotripsy has been previously shown to treat a wide range of locations through excised human skulls in vitro. In this article, a transcranial magnetic resonance (MR)-guided histotripsy (tcMRgHt) system was developed, characterized, and tested in the in vivo pig brain through an excised human skull. A 700-kHz, 128-element MR-compatible phased-array ultrasound transducer with a focal depth of 15 cm was designed and fabricated in-house.

Evaluating the role of methicillin-resistant Staphylococcus aureus (MRSA)-specific antibiotic prophylaxis for neurosurgical patients.

Objective: Surgical site infection (SSI) in neurosurgical patients increases morbidity. Despite the rise of methicillin-resistant Staphylococcus aureus (MRSA) colonization, there is little consensus regarding antibiotic prophylaxis for SSI in MRSA-colonized neurosurgical patients. Our objective was to examine the incidence of SSI in MRSA-colonized neurosurgical patients and interrogate whether MRSA-specific antibiotic prophylaxis reduces SSIs.

Neurosurgical patients admitted via the emergency department initiating comfort care measures: a prospective cohort analysis.

Background: Given the serious nature of many neurosurgical pathologies, it is common for hospitalized patients to elect comfort care (CC) over aggressive treatment. Few studies have evaluated the incidence and risk factors of CC trends in patients admitted for neurosurgical emergencies.

Objectives: To analyze all neurosurgical patients admitted to a tertiary care academic referral center via the emergency department (ED) to determine incidence and characteristics of those who initiated CC measures during their initial hospital admission.
