OBJECTIVES: Calcification of the torus tubarius has been rarely reported in the literature. Histopathologic studies have previously described cases of Eustachian tube calcification and cite an association with increasing patient age. The purpose of this study was to examine the prevalence of torus tubarius calcification and potential clinical significance on an unrestricted patient population using thin-section computed tomography (CT), which has not been previously reported. METHODS: After the institutional review board approval, 1571 consecutive patients who underwent noncontrast head CT between January 2011 and July 2011 were retrospectively reviewed for torus tubarius calcification...

BACKGROUND: Posterior spinal fusion for scoliosis is one of the most painful elective pediatric surgeries. Good postoperative pain control allows early ambulation and return of ability to tolerate oral intake. Options for analgesia in this patient population are suboptimal. We hypothesized that extended-release epidural morphine (EREM) would provide better pain control and less adverse effects compared to intrathecal (IT) morphine. METHODS: The primary outcome was total IV morphine consumption during 0-48 hours postoperatively...

BACKGROUND: The incidence of pruritus after cesarean delivery under spinal anesthesia with opioids is high, ranging from 50% to 100%. Pruritus is difficult to prevent; however, pentazocine has been shown to be an effective treatment. Despite this, the prophylactic effect of pentazocine on pruritus has not been defined. This randomized double-blind trial aimed to evaluate the effect of intraoperative IV pentazocine on the incidence of opioid-induced pruritus within the first 24 hours after administration of neuraxial opioids...

CONTEXT: Sexual and gender minority adolescents are underrepresented in HIV research, partly because institutional review boards (IRBs) are reluctant to waive parental permission requirements for these studies. Understanding teenagers' perspectives on parental permission and the risks and benefits of participating in HIV research is critical to informing evidence-based IRB decisions. METHODS: Data from 74 sexual and gender minority adolescents aged 14-17 who participated in an online focus group in 2015 were used to examine perspectives on the risks and benefits of participation in a hypothetical HIV surveillance study and the need for parental permission and adequate protections...

BACKGROUND: Use of dilute epinephrine tumescent solution in breast reduction surgery has been shown to significantly decrease operative blood loss without increasing perioperative complications. Lidocaine is commonly added to epinephrine to decrease postoperative pain. Evidence supporting this practice, however, is limited, and lidocaine toxicity has been reported. METHODS: With institutional review board approval, patients undergoing bilateral breast reduction surgery were assigned to receive either tumescent saline solution with epinephrine (1:1 million) (group 1), or tumescent saline solution with epinephrine (1:1 million) and lidocaine (0...

BACKGROUND: Analysis of systematic 12-core biopsies (SBx) has shown that African-American (AA) men tend to harbor higher risk prostate cancer (PCa) at presentation relative to other races. Multiparametric magnetic resonance imaging (mpMRI) and MRI-ultrasound fusion-guided biopsy (FBx) have been shown to diagnose more intermediate- and high-risk PCa in the general population; however, the efficacy in AA remains largely uncharacterized. We aim to evaluate the utility of FBx in an AA patient cohort...

BACKGROUND: Individuals with type 2 diabetes have an increased risk for comorbidities such as heart disease, lower limb amputations, stroke, and renal failure. Multiple factors influence development of complications in a person living with type 2 diabetes; however, an individual's self-management behaviors may delay the onset of, or lessen the severity of, these complications. Social support provides personal, informal advice and knowledge that helps individuals initiate and sustain self-management and adherence...

INTRODUCTION: End-of-shift evaluation (ESE) forms, also known as daily encounter cards, represent a subset of encounter-based assessment forms. Encounter cards have become prevalent for formative evaluation, with some suggesting a potential for summative evaluation. Our objective was to evaluate the inter-rater agreement of ESE forms using a single scripted encounter at a conference of emergency medicine (EM) educators. METHODS: Following institutional review board exemption, we created a scripted video simulating an encounter between an intern and a patient with an ankle injury...
