Does Facial Fracture Management Require Opioids? A Pilot Trial of a Narcotic-Minimizing Analgesia Protocol for Operative Facial Trauma.

Opioid minimization in the acute postoperative phase is timely in the era of the opioid epidemic. The authors hypothesize that patients with facial trauma receiving multimodal, narcotic-minimizing pain management in the perioperative period will consume fewer morphine milligram equivalents (MMEs) while maintaining adequate pain control compared with a traditional analgesia protocol. An IRB-approved pilot study evaluating isolated facial trauma patients compared 10 consecutive prospective patients of a narcotic-minimizing pain protocol beginning in August 2020 with a retrospective, chart-reviewed cohort of 10 consecutive patients before protocol implementation.

Jugular Tubercle Meningioma with Hemorrhagic Conversion Mimicking a Ruptured Thrombosed Giant Vertebrobasilar Aneurysm.

Background: Hemorrhagic meningiomas, although relatively uncommon, represent a distinct clinical entity. In some cases, these meningiomas can closely mimic a thrombosed aneurysm. We present a case of a jugular tubercle meningioma whose radiographic and clinical picture initially suggested a ruptured, thrombosed vertebrobasilar aneurysm.

Cell- and region-specific expression of depression-related protein p11 (S100a10) in the brain.

P11 (S100a10), a member of the S100 family of proteins, has widespread distribution in the vertebrate body, including in the brain, where it has a key role in membrane trafficking, vesicle secretion, and endocytosis. Recently, our laboratory has shown that a constitutive knockout of p11 (p11-KO) in mice results in a depressive-like phenotype. Furthermore, p11 has been implicated in major depressive disorder (MDD) and in the actions of antidepressants.

The influences of reproductive status and acute stress on the levels of phosphorylated delta opioid receptor immunoreactivity in rat hippocampus.

In the hippocampus, ovarian hormones and sex can alter the trafficking of delta opioid receptors (DORs) and the proportion of DORs that colocalize with the stress hormone, corticotropin releasing factor. Here, we assessed the effects of acute immobilization stress (AIS) and sex on the phosphorylation of DORs in the rat hippocampus. We first localized an antibody to phosphorylated DOR (pDOR) at the SER363 carboxy-terminal residue, and demonstrated its response to an opioid agonist.

Ovarian hormones influence corticotropin releasing factor receptor colocalization with delta opioid receptors in CA1 pyramidal cell dendrites.

Stress interacts with addictive processes to increase drug use, drug seeking, and relapse. The hippocampal formation (HF) is an important site at which stress circuits and endogenous opioid systems intersect and likely plays a critical role in the interaction between stress and drug addiction. Our prior studies demonstrate that the stress-related neuropeptide corticotropin-releasing factor (CRF) and the delta-opioid receptor (DOR) colocalize in interneuron populations in the hilus of the dentate gyrus and stratum oriens of CA1 and CA3.
