INTRODUCTION: As opioid analgesic consumption has grown, so have opioid use disorder and opioid-related overdoses. Reducing the quantity of opioid analgesics prescribed for acute non-cancer pain can potentially reduce risks to the individual receiving the prescription and to others who might unintentionally or intentionally consume any leftover tablets. Reducing the default dispense quantity for new opioid analgesic prescriptions in the electronic health record (EHR) is a promising intervention to reduce prescribing...

OBJECTIVE Trigeminal neuralgia is a debilitating pain disorder most often caused by arterial compression of the trigeminal nerve, although there are other etiologies. Microvascular decompression (MVD) remains the most definitive treatment for this disorder, with cure rates reported between 60% and 80%. Traditional MVD techniques involve a retrosigmoid craniotomy with placement of an inert foreign material, such as Teflon, between the nerve and compressive vessel. Recurrence of trigeminal neuralgia after MVD has been associated with vessel migration, adhesion formation, and arterial pulsation against the Teflon abutting the nerve...

Surgery is a central component of multimodality therapy for esophageal and gastroesophageal junction cancer. Pneumonia is a common sequela of esophagectomy, leading to an increase in intensive care unit stay, hospital stay, readmission rates, and postoperative mortality. Developing strategies to reduce pneumonia after esophagectomy is hampered by the absence of a standardized methodology for defining pneumonia. This study aims to validate the Uniform Pneumonia Score (UPS) in a high volume center in the USA...
