"Sucking the trouble" out of troubleshooting wound vacs: Video based curriculum development and implementation in a live tissue model.

We hypothesized that non-surgeon, Negative Pressure Wound Therapy (NPWT) naïve participants would better identify device functions and troubleshoot failures after being exposed to a video curriculum (VC) compared to similar participants exposed to clinical practice guidelines (CPGs). VC and critical action step development was followed by randomization of 115 non-surgical, NPWT naïve participants into either the CPG or VC study groups. Participants individually identified components of the NPWT system and then worked as a team to troubleshoot three scenarios on an in vivo porcine model.

Clinical and radiographic presentation and surgical outcomes of TPIT+ silent corticotroph pituitary neuroendocrine tumors: a multi-institutional experience and review of the literature.

Background: Accurate lineage identification of pituitary neuroendocrine tumors (PitNETs) is critical to inform our understanding of tumor biology and aggressiveness. While this was previously performed using immunohistochemistry for anterior pituitary hormones, the recent WHO update using lineage specific transcription factors (PIT-1, SF-1, TPIT) has led to improved classification of PitNETs. Although the identification of TPIT, a T-box pituitary transcription factor, has afforded improved classification of corticotroph PitNETs from what were previously thought to be null cell adenomas, the standardization of lineage specific transcription factor staining has yet to be fully adopted and as a result the clinical aggressivness and outcomes of these newly classified silent TPIT+ PitNETs has yet to be fully described.

Aging and visual pattern detection.

A single psychophysical experiment evaluated observers' ability to detect visual patterns embedded in noise; effects of stimulus complexity and observer age were also evaluated. Eighteen younger and older observers participated in the experiment (mean ages were 20.3 and 72.

Resolution of Refractory Status Epilepticus With Ketamine Without Intubation in a Patient With Stroke-Like Migraine Attacks After Radiation Therapy (SMART) Syndrome.

Stroke-like migraine attacks after radiation therapy (SMART) syndrome is an infrequently reported complication arising years after radiation therapy that manifests as a reversible syndrome marked by migraine-like headaches, focal neurologic signs, and/or seizures. Refractory status epilepticus (RSE) associated with SMART syndrome is rare and can be challenging to treat. Valproic acid has been reported to improve seizures in RSE in SMART syndrome in a few case reports and may be ideal for SMART syndrome, given its use in the treatment of migraines and seizures.
