The Role of Obesity in Motor Vehicle Injuries and Fatalities in the Pediatric Population: A Systematic Review.

PURPOSE: A systematic review done to evaluate obesity as a risk factor for injuries and mortality in motor vehicle accidents (MVAs) in the pediatric population, as there has not been a systematic review done in over 10 years. This study aims to update the literature regarding obesity as a risk factor for injuries in MVAs in the pediatric population. MATERIALS AND METHODS: A systematic review was conducted according to the PRISMA guidelines with strict inclusion and exclusion criteria, resulting in the use of 3 total articles to analyze obesity as a risk factor for overall injury and mortality in the pediatric population. RESULTS: Zaveri et al demonstrated a statistically significant, but weak, decrease in the odds of extremity injury in overweight patients ages 2 to 17 years old (odds ratio [OR] = 0.6, 95% confidence interval [CI] = 0.4-1.0, P ≤ 0.05). On the other hand, Pollack et al and Haricharan et al found an increase in extremity injury in the obese population, in ages 9 to 15 years (OR = 2.54, 95% CI = 1.15-5.59, P ≤ 0.05), and 10 to 17 years (Age 10-13: OR = 6.06, 95% CI = 2.23-16.44, P ≤ 0.05, Age 14-17 OR = 1.44, 95% CI = 1.04-2.00, P ≤ 0.05), respectively. Haricharan et al also found an increase in thoracic injuries in obese children, ages 2 to 13 and increased risk of head/face/neck injury in obese children ages 2 to 5 (OR = 3.67, 95% CI = 1.03-13.08, P ≤ 0.05), but a decreased risk of head injury in obese children ages 14 to 17 (OR = 0.33, 95% CI = 0.18-0.60, P ≤ 0.05). CONCLUSIONS: There are sparse data that are conflicting, regarding the effect of obesity on extremity injuries in the pediatric population. Obesity is not protective against thoracic, head, or abdominal injuries. However, it was found to be a risk factor for trunk injuries in ages 2 to 13, as well as head/face/neck injuries for ages 2 to 5. Since the literature is so sparse, further research is warranted in these areas.

Current Trends in the Use of Ultrasound Over Chest X-Ray to Identify Pneumothoraces in ICU, Trauma, and ARDS Patients.

Pneumothoraces are a common and potentially fatal complication for critically ill patients in the trauma and intensive care units. Since its use for pneumothorax detection was first reported in 1987, ultrasound has been increasingly used for the detection of thoracic injuries. As ultrasound imaging has improved and operators have potentially become more proficient, it is important to analyze more recent trends in the sensitivities and specificities of ultrasound for the detection of pneumothorax. This literature review and meta-analysis identifies 17 studies that directly compare the sensitivity and specificity of ultrasound and anterior-posterior chest x-ray in the identification of pneumothorax among 2955 patients who developed 793 pneumothoraces as detected by gold standard CT scanning. For the 17 articles analyzed, the pooled sensitivity of trans-thoracic ultrasound was 75.07% (64.92%-85.22%), and the pooled specificity was 98.36% (97.45%-99.26%). The pooled sensitivity of CXR was 45.65% (36.04%-55.26%), and pooled specificity was 99.62% (99.00%-100%). While this review demonstrates an improved sensitivity in the detection of pneumothorax with ultrasound over AP chest x-rays, it did not find a significant trend or improvement in the sensitivity or specificity of ultrasound for detecting pneumothorax over time.

Assessing the Cushion Effect: A Systematic Review and Meta-Analysis of the Role of Obesity in Motor Vehicle Injuries and Fatalities.

PURPOSE: A systematic review and meta-analysis were done to evaluate the effect of obesity in injury and mortality due to motor vehicle accidents. MATERIALS & METHODS: The systematic review consisted of 20 studies meeting the inclusion criteria. The meta-analysis was conducted on these studies to analyze obesity as a risk factor for specific injuries, as well as overall injury and mortality compared to non-obese patients. RESULTS: The data revealed that obesity was associated with increased lower extremity injuries (odds ratio [OR] = 1.44, 95% confidence interval [CI] = 1.19-1.69, P ≤ 0.05), neck injuries (OR = 3.38, 95% CI = 1.58-5.19, P ≤ 0.05), and overall mortality (OR = 1.51, 95% CI = 1.40-1.61, P ≤ 0.05). When stratified for obesity class with class I as BMI >30.1-34.9, class II BMI 35-39.9, and class III BMI >40, only class II (OR = 1.20, 95% CI = 1.15-1.24, P ≤ 0.05) and class III (OR = 1.49, 95% CI = 1.30-1.68, P ≤ 0.05) were associated with increased mortality risk. No significant differences were seen with head, upper extremity, thoracic, abdominal, or pelvic injuries. CONCLUSION: Obesity is a risk factor in motor vehicle accidents for fatality and injury, specifically lower extremity and neck injuries.

Cardiopulmonary resuscitation and skill retention in emergency physicians.

STUDY OBJECTIVES: The American Heart Association (AHA) recently established the Resuscitation Quality Improvement (RQI) program, which requires physicians to perform quarterly cardiopulmonary resuscitation (CPR) skill checks. The aim of this study was to determine if timing of last training impacted skill performance of emergency physicians. METHODS: A convenience sample of emergency medicine (EM) physicians was asked to complete a Basic Life Support (BLS) scenario on a manikin. Participants passed the scenario if they successfully performed high-quality CPR. Participants completed a survey to assess clinical experience and timing of prior BLS training. Outcomes were comparisons of skills check pass rates for physicians recently trained in BLS (≤90 days) and those trained >90 days ago and those trained >2 years ago. RESULTS: A total of 113 individuals were included in the study: 87 attending physicians and 26 residents. Overall 92.9% correctly performed CPR with the proper assessment, compression rate, compression depth and rescue breaths. There was no difference between success rates in EM physicians who had BLS training within 90 days (91.7%) and physicians who had not had BLS within 90 days, (93.1%). (p = 1.00) There was no difference in the pass rate of those trained within 90 days (91.7%) to those trained >2 years ago (90.9%) (95CI 0.088, 0.096). CONCLUSION: There was no difference between delivery of high-quality CPR in EM physicians who had recent BLS training and those who did not.

A Comprehensive Review of Over-the-counter Treatment for Chronic Migraine Headaches.

PURPOSE OF REVIEW: Migraine headaches are a neurologic disorder characterized by attacks of moderate to severe throbbing headache that are typically unilateral, exacerbated by physical activity, and associated with phonophobia, photophobia, nausea, and vomiting. In the USA, the overall age-adjusted prevalence of migraine in female and male adults is 22.3% and 10.8%, respectively. RECENT FINDINGS: Migraine is a disabling disease that ranks as the 8th most burdensome disease in the world and the 4th most in women. The overarching hypothesis of migraine pathophysiology describes migraine as a disorder of the pain modulating system, caused by disruptions of the normal neural networks of the head. The activation of these vascular networks results in meningeal vasodilation and inflammation, which is perceived as head pain. The primary goals of acute migraine therapy are to reduce attack duration and severity. Current evidence-based therapies for acute migraine attacks include acetaminophen, four nonsteroidal anti-inflammatory drugs (NSAIDs), seven triptans, NSAID-triptan combinations, dihydroergotamine, non-opioid combination analgesics, and several anti-emetics. Over-the-counter medications are an important component of migraine therapy and are considered a first-line therapy for most migraineurs. These medications, such as acetaminophen, ibuprofen, naproxen, and aspirin, have shown strong efficacy when used as first-line treatments for mild-to-moderate migraine attacks. The lower cost of over-the-counter medications compared with prescription medications also makes them a preferred therapy for some patients. In addition to their efficacy and lower cost, over-the-counter medications generally have fewer and less severe adverse effects, have more favorable routes of administration (oral vs. subcutaneous injection), and reduced abuse potential. The purpose of this review is to provide a comprehensive evidence-based update of over-the-counter pharmacologic options for chronic migraines.

Newly Diagnosed Multiple Sclerosis Presenting as Brown-Séquard Syndrome: A Case Report.

INTRODUCTION: Brown-Séquard syndrome is a rare neurological disorder due to hemisection of the spinal cord that can occur from a variety of causes, most commonly trauma. CASE REPORT: We present a case of a 25-year-old woman presenting with Brown-Séquard syndrome as her first clinical presentation of multiple sclerosis. CONCLUSION: This case highlights the need to have demyelinating disease on the differential as an exceedingly rare, but important, possible cause of Brown-Séquard syndrome.

The Feasibility of Virtual Reality and Student-Led Simulation Training as Methods of Lumbar Puncture Instruction.

BACKGROUND: There is limited data assessing simulation and virtual reality training as a standardized tool in medical education. This feasibility study aimed to evaluate the effectiveness of virtual reality training and a student-led simulation module in preparing medical students to perform a lumbar puncture. METHODS: Twenty-five medical students completed a pre-intervention survey, and a baseline video recorded lumbar puncture procedure on a task trainer. Students were randomly distributed into the virtual reality group, or the curriculum's standard student-led procedural instruction group. Participants were then given 45 min to practice the lumbar puncture procedure. After the intervention, all participants were video recorded again as they performed a post-intervention lumbar puncture and completed a post-intervention survey. Pre- and post-intervention videos were scored using a critical action checklist in conjunction with time needed to complete the procedure to evaluate proficiency. RESULTS: At baseline, there were no major statistically significant differences between groups. Assessing overall post-intervention performance, both groups showed improvement in aggregate score (p < 0.001) and time required to complete (p = 0.002) the lumbar puncture. Following interventions, the student-led group improved over the virtual reality group in a variety of metrics. The student-led group increased their aggregate score by 3.49 and decreased their time to completion by 34 s over the VR group when controlling for baseline measures. CONCLUSIONS: Both virtual reality and student-led simulation training were useful training modalities, with hands-on simulation showing better results versus virtual reality training in this setting.
