Objective: To evaluate the effect of acute postoperative alcohol withdrawal on survival of vascularized fibular grafts for mandibular reconstruction.
Design: Retrospective case series of 17 consecutive patients.
Main Outcomes Measure: Relation between flap survival and alcohol withdrawal.
Results: Flap survival rate was 25% for patients who experienced delirium tremens and 85% in the other patients. Had all flaps in patients with postoperative alcohol withdrawal survived, the success rate would have been 89%. Flap loss was related to acute alcohol withdrawal (P =.02, chi2 analysis). The relationship between complication rate and alcohol withdrawal was also significant, using the Fisher exact test.
Conclusions: Fibular free flap reconstruction of the mandible is clearly cost-effective when it facilitates return to social function and productivity. In our experience, acute alcohol withdrawal in the first 72 hours after surgery is associated with a high incidence of flap loss. Therefore, we believe that patients at significant risk for alcohol withdrawal should undergo detoxification preoperatively. Society's economic return for investing in free flap reconstruction comes from minimizing convalescence and maximizing postoperative patient productivity. This return will not be realized for poorly selected patients. We are looking further into the effects of alcoholism on flap survival rates.

The N-methyl-D-aspartate (NMDA) glutamate receptor is a major target of ethanol, and it is implicated in learning and memory formation, and other cognitive functions. Glycine acts as a co-agonist for this receptor. We examined whether Org24598, a selective inhibitor of glycine transporter1 (GlyT1), affects ethanol withdrawal-induced deficits in recognition memory (Novel Object Recognition (NOR) task) and spatial memory (Barnes Maze (BM) task) in rats, and whether the NMDA receptor glycine site participates in this phenomenon.

During the COVID-19 pandemic, reducing aerosol-generating procedures became fundamental, particularly in ophthalmic surgeries traditionally performed under general anesthesia (GA). Regional anesthesia, such as sub-Tenon's block (STB), is widely used in vitreoretinal surgeries, offering a safer alternative by avoiding airway manipulation. However, the altered orbital anatomy in patients with previous scleral explant surgery creates unique challenges to STB application.

Substance use disorders (SUDs) and anxiety disorders (ADs) are highly comorbid, a co-occurrence linked to worse clinical outcomes than either condition alone. While the neurobiological mechanisms involved in SUDs and anxiety disorders are intensively studied separately, the mechanisms underlying their comorbidity remain an emerging area of interest. This narrative review explores the neurobiological processes underlying this comorbidity, using the Research Domain Criteria (RDoC) framework to map disruptions in positive valence, negative valence, and cognitive systems across the three stages of the addiction cycle: binge/intoxication, withdrawal/negative affect, and preoccupation/anticipation.

Background: There are many barriers to prescribing medications for opioid use disorder (MOUD). This study evaluates the prevalence, patterns, and predictors of inpatient MOUD prescribing at discharge to patients with a diagnosis of opioid use/opioid use disorder (OUD) that developed opioid withdrawal during their hospital stay.
Methods: This multicenter, retrospective cross-sectional study occurred at three hospitals in Arizona.
