Predicting Secondary Decline after TBI

Wendy Chang, MD, collaborated with investigators from the Departments of Neurology, Anesthesiology, and Surgery in an analysis of clinical information from patients enrolled in the Oximetry and Noninvasive Predictors of Intervention Need after Trauma (ONPOINT) study. They concluded that continuous vital sign variability and waveform analysis of the electrocardiogram or photoplethysmogram within the first hour after resuscitation constitutes a noninvasive marker of neurologic decline after traumatic brain injury.

Their work was published as the following article:

Senator Van Hollen Meets with ED Physicians

US Senator Chris Van Hollen (D-MD) visited UMMC's emergency department on November 1 to discuss the effects of the opioid crisis on ED operations, the use fentanyl among ED patients, and the administration of buprenorphine to patients seeking treatment or in withdrawal. Joining in that conversation were (left to right) Mohan Suntha, MD, MBA, President and Chief Executive Officer, University of Maryland Medical Center, Michael E. Winters, MD, MBA, Senator Van Hollen, Stephen R. Thom, MD, PhD, Zachary D.W. Dezman, MD, MS, MS, and Eric Weintraub, MD, Department of Psychiatry.

Dr. Mattu Presents Cardiology Course in Florida

Amal Mattu, MD, conducted a 21-hour course on emergency cardiology in Sarasota, Florida, from October 22 to 26. The CME course, titled "Emergency Cardiology: Beyond A-B-C and ACLS," was sponsored by American Medical Seminars. Content included electrocardiographic workshops covering cardiac ischemia and its mimics, advanced dysrhythmia recognition and management, and critical ECG findings in patients with syncope. In addition, Dr. Mattu presented lectures on cardiogenic pulmonary edema, cardiac arrest, acute coronary syndromes, low-risk chest pain, and legal pitfalls in emergency cardiology. The course was attended by over 100 health care providers in emergency medicine, internal medicine, family medicine, anesthesiology, cardiology, cardiothoracic surgery, and critical care from the United States, Canada, and the Caribbean.

Zachary Dezman, MD, MS, MS, and Jon Mark Hirshon, MD, PhD, MHS, co-authored the article titled "Repeat Lactate Level Predicts Mortality Better Than Rate of Clearance," pubilshed in the November issue of American Journal of Emergency Medicine. Their collaborators in this project were three investigators who have been studying the fine points of trauma epidemiology and resuscitation for decades: Peter Hu, MS, PhD, and Colin Mackenzie, MD,ChB, from the Department of Anesthesiology, and Gordon Smith, MB,ChB, MPH, from the Department of Epidemiology and Pubic Health, as well as Thomas Scalea, MD, The Honorable Francis X. Kelly Distinguished Professor in Trauma Surgery. The statistician for this work was Angela Comer, MS, formerly affliated with the National Study Center for Trauma and Emergency Medical Systems.

The use of buprenorphine in the ED at UMMC’s Midtown Campus is discussed in a recent article in the Washington Post:

In that article, Dr. Zachary Dezman explains that opioid-addicted patients seen “after hours” are offered an initial dose of the anti-addiction medication rather than simply being sent home and advised to go to a treatment center. Numerous studies have shown this “jumpstart” on treatment to be effective in helping people seek help and eventually kick their habit.

An unusual consequence of unconsciousness is described in a case report published earlier this month by Eric Friedman, MD, and Ken Butler, DO. “Not Just Another 'Found Down': Concomitant Upper Arm and Gluteal Compartment Syndrome” is available at the website of The Journal of Emergency Medicine (

Dr. Dezman on Fox45 News This Morning

Zachary Dezman, MD, MS, MS, was a guest on today's morning news broadcast from Fox45, discussing the surprising results of a study designed to identify drugs used by ED patients being treated for overdose. You can watch the full segment here:

Marijuana was the individual drug most commonly detected. Only one sample tested positive for a synthetic cannabinoid. The results suggest that street drugs are being packaged in new combinations not detected by standard ED tests. The investigators also found that the drugs patients claimed to have taken (and the drugs the physicians assumed they had taken) often did not match the metabolites detected by the analysis.

The study and its findings are more fully described at this site:

Jenny Guyther, MD, and Rich Lichenstein, MD, are the lead authors of the article titled "Association of Influenza Outbreaks with Advanced Pediatric Medical Support," published in the August issue of Epidemiology & Infection (2018;146:1366-71). Their study documented increased hospitalizations and ICU admissions as well as the use of mechanical ventilation during influenza outbreaks by children with medically attended acute respiratory illness.
