Analysis of Transport to an American College of Surgeons Level I Trauma Center.

INTRODUCTION: Efficient patient transportation by ground emergency medical services (GEMS) or helicopter emergency medical services (HEMS) to a trauma center is vital for optimal care. We investigated differences between the modes of transport in terms of demographics, injury, scene location, and outcome. SETTING: Morristown Medical Center (MMC), Morristown, NJ METHODS: All 903 trauma admissions in 2016 by advanced life support (ALS) to MMC, a Level I Trauma Center, were retrospectively analyzed. RESULTS: 22% of admissions were HEMS and 78% were GEMS. HEMS patients had higher Injury Severity Scores (ISS) (p<0.001); however, mortality and length of stay were not statistically different. The percentage of pediatric patients transported by HEMS that were discharged home after emergency department evaluation was greater than the older populations (p<0.001). Older age and higher ISS had the largest impact on mortality (p<0.001). CONCLUSION: We believe our current use of HEMS is adequate since patient outcomes between HEMS and GEMS was similar, even though HEMS patients have higher ISS. However, helicopter use in the pediatric population was over-utilized, possibly due to the scarcity of hospitals capable of managing pediatric traumas. Implementation of the Air Medical Prehospital Triage scoring system may also help correct for these unnecessary HEMS transports.

Understanding Herpes Simplex Virus Type 1 Versus Herpes Simplex Virus Type 2 Encephalitis After Neurosurgery: A Case Series and Literature Review.

Abstract Background: Herpes simplex virus encephalitis (HSVE) is a rare post-operative infection that can be fatal if treatment is delayed. Herpes simplex virus type 1 (HSV-1) is a more common cause of encephalitis than herpes simplex virus type 2 (HSV-2), however, a significant overlap exists. The goal of this project was to understand the frequency and trend of HSVE after neurosurgery through a case series at our institution and in the literature with a focus on comparing HSV-1 versus HSV-2. Patients and Methods: A literature review of all published cases and case series of HSVE after neurosurgery was performed. Descriptive statistics comparing HSV-1 and HSV-2 encephalitis were computed. Data on demographics, symptoms, surgery, treatment, immunosuppression, imaging findings, steroids, and mortality were collected. Results: We identified 55 total cases of HSVE post-neurosurgery. These included 28 cases of HSV-1, 10 cases of HSV-2, and 17 cases of HSV-unspecified encephalitis. There were no differences in age, gender, symptoms, surgery, or latency between surgery and symptom onset between HSV-1 and HSV-2. Mortality was higher with HSV-1 versus HSV-2 although not statistically significant. The primary surgical indication varied substantially between HSV-1 and HSV-2. Conclusions: Herpes simplex virus encephalitis is often overlooked in the setting of encephalitis after surgery. A high index of suspicion is needed to prevent a delay in treatment.

A Case of Sensorineural Hearing Loss in Wernicke Encephalopathy.

Extremely rare cases of Wernicke encephalopathy (WE) can involve sensorineural hearing loss (SNHL). Here, we present a 46-year-old female with SNHL and clinical and radiologic suspicion for WE. After initiating thiamine therapy, the patient experienced robust improvement. Laryngoscope, 133:1492-1494, 2023.
