Magnetic resonance imaging-guided focused ultrasound thalamotomy for essential tremor in a patient with von Willebrand disease: perioperative optimization for patients with coagulopathies. Illustrative case.

Background: Essential tremor (ET) is one of the most common movement disorders worldwide. In medically refractory ET, deep brain stimulation (DBS) of the ventral intermediate nucleus of the thalamus is the current standard of care. However, DBS carries an inherent 2% to 3% risk of hemorrhage, a risk that can be much higher in patients with concomitant coagulopathy.

The history of antibiotic irrigation and prophylaxis in operative neurotrauma: perpetuation of military care in civilian settings.

The benefit of antibiotic irrigation for prophylaxis against wound infections, not only for traumatic cranial injuries but also in elective neurosurgical care, has recently been called into question. Several articles have cast doubt on the utility of topical antibiotics, and recently, bacitracin irrigation was made unavailable in some US markets. The pervasive nature of antibiotic irrigation, considering the lack of evidence supporting its use, led the authors to question when and how neurosurgeons started using antibiotic irrigation in cranial neurosurgery.

Frequency-specific medial septal nucleus deep brain stimulation improves spatial memory in MK-801-treated male rats.

Background: Few treatments exist for the cognitive symptoms of schizophrenia. Pharmacological agents resulting in glutamate N-methyl-d-aspartate (NMDA) receptor hypofunction, such as MK-801, mimic many of these symptoms and disrupt neural activity. Recent evidence suggests that deep brain stimulation (DBS) of the medial septal nucleus (MSN) can modulate medial prefrontal cortex (mPFC) and hippocampal activity and improve spatial memory.

Environmental conditions in maternity wards: Evidence from rural healthcare facilities in 14 low- and middle-income countries.

Adequate environmental conditions, comprising sufficient environmental hygiene items (e.g. gloves, soap, and disinfectant), adequate infrastructure (e.
