An Unusual Presentation of a Lymphatic Malformation in an Adult: A Case Report.

INTRODUCTION: Patients commonly present with neck masses to the Emergency Department. The acute presentation of such a mass can be alarming to patients and their families. In this report we discuss a rare etiology of an acutely presenting neck mass in an adult. CASE REPORT: We present a 19-year-old patient with an acute neck mass. The mass developed abruptly soon after initiation of a new upper body strength-training regimen. The patient's history was unremarkable for any trauma or constitutional symptoms. Physical examination revealed the mass, which was diagnosed as a lymphatic malformation by imaging. Surgical removal was successful with pathology confirming the diagnosis. CONCLUSION: Lymphatic malformations, although rare, may present in adulthood. The acute presentation of a new mass, coupled with a lack of concerning constitutional symptoms, should increase the diagnostic suspicion of a lymphatic malformation.

The Effect of State Legislation on Opioid Prescriptions Following Arthroscopic Rotator Cuff Repair.

New Jersey State Law, P.L. 2017 Chapter 28 22, C.24:21-15.2, passed in February 2017, is the most restrictive opioid legislation passed thus far in the United States. This study evaluated the effects of this legislation on the postoperative opioid prescriptions of patients undergoing arthroscopic rotator cuff repair (RCR). Opioid prescriptions were compared following arthroscopic RCR before and after implementation of the new law using the New Jersey Prescription Monitoring Program Aware Drug Database. A consecutive cohort of patients who underwent RCR during a 6-month period prior to the legislation was compared with a consecutive cohort of patients who underwent RCR during a 6-month period after the law went into effect. The primary outcome measure was prescribed postoperative milligram morphine equivalents (MME) and number of pills prescribed. There were 265 patients in the pre-law cohort and 198 patients in the post-law cohort. In the pre-law cohort, there was a median of 1250 MME (interquartile range [IQR], 900-1800 MME) and a median of 100 pills (IQR, 60-175 pills) prescribed postoperatively. In the post-law cohort, a median of 900 MME (IQR, 550-1050 MME) and a median of 60 pills (IQR, 60-90 pills) were prescribed postoperatively. A comparison of pre-law and post-law data for MME and number of pills prescribed was statistically significant (P<.001). The median opioid consumption MME and number of pills prescribed following RCR decreased significantly following the implementation of the New Jersey state law. Findings of this study indicate state regulations may play a role in reducing narcotic consumption following RCR. [Orthopedics. 2021;44(1):e80-e84.].

Pulseless Electrical Activity Cardiac Arrest.

Audience: This simulation-based scenario is appropriate for senior level emergency medicine residents. Introduction: Pulseless electrical activity (PEA) accounts for up to 25% of sudden cardiac arrest;1 therefore the ability to recognize and care for this condition is an essential skill of emergency medicine physicians. Management of PEA arrest in the emergency department centers on Advanced Cardiac Life Support (ACLS) algorithms and the identification and treatment of potentially reversible causes. Massive pulmonary embolism (PE) is one of several causes of PEA cardiac arrest.2 However, diagnosis by CT-angiographic or nuclear imaging may not be obtainable in the hemodynamically unstable patient, requiring physicians to have a high index of suspicion. Systemic thrombolytic therapy is indicated in cardiac arrest due to known or presumed massive pulmonary embolism.3,4,5. Educational Objectives: After competing this simulation-based session, the learner will be able to:Identify PEA arrestReview the ACLS commonly recognized PEA arrest etiologies via the H &T mnemonicReview and discuss the risks and benefits of tissue plasminogen activator (tPA) for massive PE. Educational Methods: This is a high-fidelity simulation that allows learners to evaluate and treat a PEA arrest secondary to massive PE in a safe environment. The learners will demonstrate their ability to recognize a PEA arrest, sort through possible etiologies, and demonstrate treatment of a massive PE with tPA. Debriefing will focus on diagnosis and management of the PEA arrest. Research Methods: This case was piloted with 12 PGY-2 and PGY-3 residents. Group and individual debriefing occurred post-case. Results: Post-simulation feedback from the faculty suggested two potential issues. First was fidelity, which we increased by using our ultrasound simulator. Second, the elevated presenting glucose with lactic acidosis could be a poor cue, leading some towards diabetic ketoacidosis (DKA). Discussion: Learners felt more confident about running a PEA arrest. The simulation improved resident awareness of the value of point of care ultrasound (POCUS) in cardiac arrest. It also clarified the dosing of tPA in massive PE. Faculty felt simulating the actual US without breaking simulation would be more challenging without our US simulator. Although there was concern about results pointing towards possible DKA, this did not occur in any of the pilot simulations. The presenting glucose was reduced to make this less likely in future simulations.
