Randomized Controlled TrialPreparing for obstetric anaesthesia - an educational randomised controlled trial comparing e-learning to written course material.
E-learning is increasingly used in postgraduate medical education. Its numerous benefits include an enhanced learning experience through learning style individualisation, interactive elements, and assessment through tests and quizzes. Current meta-analyses conclude that the overall effectiveness of e-learning is comparable to traditional teaching modalities. However, studies demonstrating its benefits are heterogeneous and of varying quality. This randomised controlled trial aims to investigate whether contemporary e-learning completed prior to a course in obstetric anaesthesia prepares the course participants better than self-study of written course material. ⋯ This blinded parallel group randomised controlled trial found a numerically small but statistically significant difference in knowledge favouring e-learning over written course material.

Duration of Prophylactic Levetiracetam After Surgery for Brain Tumor: A Prospective Randomized Trial.
Levetiracetam is commonly used as a prophylactic antiseizure medication in patients undergoing surgical resection of brain tumors. ⋯ The use of prophylactic levetiracetam did not result in significant neurotoxicity or depression when given for either 1 week or 6 weeks. The incidence of seizure after craniotomy for tumor resection is low regardless of duration of therapy.

The Untrained Public's Ability to Apply the Layperson Audiovisual Assist Tourniquet vs a Combat Application Tourniquet: A Randomized Controlled Trial.
Although the Stop the Bleed campaign's impact is encouraging, gaps remain. These gaps include rapid skill decay, a lack of easy-to-use tourniquets for the untrained public, and training barriers that prevent scalability. A team of academic and industry partners developed the Layperson Audiovisual Assist Tourniquet (LAVA TQ)-the first audiovisual-enabled tourniquet for public use. LAVA TQ addresses known tourniquet application challenges and is novel in its design and technology. ⋯ The untrained public is 4 times more likely to apply LAVA TQ correctly than CAT. The public also applies LAVA TQ faster than CAT and has more favorable opinions about its usability. LAVA TQ's highly intuitive design and built-in audiovisual guidance solve known problems of layperson education and skill retention and could improve public bleeding control.

Ocular Optical Coherence Tomography in the Evaluation of Sellar and Parasellar Masses: A Review.
Compression of the anterior visual pathways by sellar and parasellar masses can produce irreversible and devastating visual loss. Optical coherence tomography (OCT) is a noninvasive high-resolution ocular imaging modality routinely used in ophthalmology clinics for qualitative and quantitative analysis of optic nerve and retinal structures, including the retinal ganglion cells. By demonstrating structural loss of the retinal ganglion cells whose axons form the optic nerve before decussating in the optic chiasm, OCT imaging of the optic nerve and retina provides an excellent tool for detection and monitoring of compressive optic neuropathies and chiasmopathies due to sellar and parasellar masses. ⋯ Preoperative values of OCT optic nerve and macular parameters represent a prognostic tool for postoperative visual outcome. This review provides a qualitative analysis of the current applications of OCT imaging of the retina and optic nerve in patients with anterior visual pathway compression from sellar and parasellar masses. We also review the role of new technologies such as OCT-angiography, which could improve the prognostic ability of OCT to predict postoperative visual function.
