Training and Practice Settings of Physicians Dual-Certified in Emergency and Sports Medicine.

ABSTRACT: Survey study of training and practice paradigms and job satisfaction of dual-boarded emergency medicine (EM) and sports medicine (SM) physicians. The REDCap survey was sent to 193 American Board of EM members who hold a Certificate of Added Qualification in SM. A total of 124 EM/SM physicians responded (67.5% male). More than 70% completed three-year residencies while only 28.5% had an EM/SM residency faculty. One-quarter delayed fellowship after residency 6.45 years on average. Regarding their first job after fellowship, 27.6% practiced only EM, 54.5% practiced both EM and SM, and 12.2% practiced only SM. Regarding their current job, 29.1% practice only EM. 47.3% practice both EM and SM, and 20.9% practice only SM. Only 13.9% and 9.9% indicated they are unhappy with their first job and current job, respectively. There is significant variability in practice settings for EM/SM physicians with the overwhelming majority being happy with their career choices.

Shoulder Pseudodislocation Associated with Calcific Tendinitis/Bursitis and Diagnosed by Point of Care Ultrasound.

BACKGROUND: Shoulder pseudodislocation, or "drooping shoulder," presents with acute pain and deformity of the joint, with radiographs demonstrating inferior subluxation of the humeral head relative to the glenoid fossa. The diagnosis must be made promptly and distinguished from true glenohumeral dislocation, both to avoid unnecessary attempts at closed reduction and to facilitate investigation of the underlying cause, which may include septic arthritis, hemarthrosis, or other emergent etiologies. Point-of-care ultrasound (POCUS) may be useful in the evaluation of emergency department (ED) patients with suspected pseudodislocation. CASE REPORT: A 50-year old female presented to the ED with an acutely painful and deformed shoulder but atypical history and physical examination. Initial radiography appeared to show a glenohumeral dislocation, but POCUS, done to guide intra-articular lidocaine injection, led to recognition of pseudodislocation and subsequent diagnosis of calcific tendinitis/bursitis, a condition not previously associated with inferior humeral subluxation. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Shoulder pseudodislocation must be considered in the evaluation of patients with suspected glenohumeral dislocation, but atypical features on history, physical examination, or initial plain radiography. POCUS may facilitate prompt diagnosis and identification of the underlying etiology.

Use of Tandem Perimortem Cesarean Section and Open-Chest Cardiac Massage in the Resuscitation of Peripartum Cardiomyopathy Cardiac Arrest.

Cardiac arrest and resuscitation of the pregnant woman at gestational term is rare. Depending on the circumstances of cardiac arrest and its timing, options are limited for allowing successful resuscitation of both mother and neonate. Herein, we describe the use of tandem perimortem cesarean section and thoracotomy for open-chest cardiac massage in a young woman with newly diagnosed peripartum cardiomyopathy. We used goal-directed resuscitation including diagnostic ultrasonography and capnography to assist in decision making and successfully resuscitated both mother and neonate to hospital discharge without discernable long-term complications.

Balance Assessment in Sports-Related Concussion: Evaluating Test-Retest Reliability of the Equilibrate System.

This study evaluated the test-retest reliability of a novel computer-based, portable balance assessment tool, the Equilibrate System (ES), used to diagnose sports-related concussion. Twenty-seven students participated in ES testing consisting of three sessions over 4 weeks. The modified Balance Error Scoring System was performed. For each participant, test-retest reliability was established using the intraclass correlation coefficient (ICC). The ES test-retest reliability from baseline to week 2 produced an ICC value of 0.495 (95% CI, 0.123-0.745). Week 2 testing produced ICC values of 0.602 (95% CI, 0.279-0.803) and 0.610 (95% CI, 0.299-0.804), respectively. All other single measures test-retest reliability values produced poor ICC values. Same-day ES testing showed fair to good test-retest reliability while interweek measures displayed poor to fair test-retest reliability. Testing conditions should be controlled when using computerized balance assessment methods. ES testing should only be used as a part of a comprehensive assessment.

Foot evaluation via telephone and video virtual medical visits.

BACKGROUND: Telemedicine plays a very important role in our society by allowing providers to treat patients who do not have easy access to a healthcare facility, especially in the setting of the COVID-19 pandemic. OBJECTIVE: We aimed to create an extensive, yet concise guide for medical providers to virtually evaluate patients with foot concerns. METHODS: This article outlines how to conduct a well-planned virtual consultation with specific questions, instructions, and examination manoeuvres to navigate musculoskeletal foot problems. CONCLUSION: With this narrative review, we have provided a guide with suggestions, questions and interpretations of answers to help physicians new to the practice of telemedicine have successful virtual encounters with patients suffering from foot musculoskeletal ailments.

Effect of sex on symptoms and return to baseline in sport-related concussion.

OBJECT: Sport-related concussions (SRCs) among youth athletes represent a significant public health concern. Prior research suggests that females fare worse symptomatically after an SRC. The authors aimed to assess sex differences in number, severity, and resolution of postconcussive symptoms using reliable change index (RCI) methodology applied to days to return to symptom baseline. METHODS: Between 2009 and 2011, 740 youth athletes completed valid neurocognitive and symptom testing before and after an SRC using Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT). A total of 122 female and 122 male athletes were matched on number of prior concussions, age, and number of days to first postconcussion test. At baseline and postconcussion, the authors compared each of the individual 22 symptoms on ImPACT to calculate individual symptom severity and aggregate symptom severity, or the Total Symptom Score (TSS). When comparing individual symptoms, the significance level for the comparison of each symptom was set at 0.05/22 = 0.0023. When comparing aggregate symptom severity, or TSS, a single value was compared, requiring an alpha set to 0.05. The number of days to return to baseline TSS was compared using RCI methods set at the 80% confidence interval, equal to a raw score point value of 9.18 on the TSS. RESULTS: At baseline, females reported a greater severity for the symptom, "sleeping less than usual," compared with males (0.88 ± 1.49 vs 0.31 ± 0.86, p < 0.001). However, no other individual symptom severity differences were noted before or after SRC. At baseline, females exhibited a statistically significant greater aggregate symptom severity than males (7.24 ± 10.22 vs 4.10 ± 6.52, p = 0.005). Greater aggregate symptom severity for females was also found postconcussion (21.38 ± 19.02 vs 16.80 ± 17.07, p = 0.049). Females took longer to return to baseline TSS (9.1 ± 7.1 days vs 7.0 ± 5.1 days, p = 0.013). CONCLUSIONS: The results of this retrospective study indicate that females endorse a greater severity of symptoms at baseline and postconcussion than males without significantly different symptom profiles. Furthermore, after suffering an SRC, females take longer to return to their baseline symptom level.

The role of magnesium in the management of cerebral vasospasm.

Subarachnoid hemorrhage (SAH) is characterized by bleeding into the subarachnoid space, often caused by ruptured aneurysm. Aneurysmal rupture occurs in 700,000 individuals per year worldwide, with 40,000 cases taking place in the United States. Beyond the high mortality associated with SAH alone, morbidity and mortality are further increased with the occurrence of cerebral vasospasm, a pathologic constriction of blood vessels that can lead to delayed ischemic neurologic deficits (DIND). Treatment of cerebral vasospasm is a source of contention. One extensively studied therapy is Magnesium (Mg) as both a competitive antagonist of calcium at the N-methyl D-aspartate (NMDA) receptor, and a noncompetitive antagonist of both IP3 and voltage-gated calcium channels, leading to smooth muscle relaxation. In our literature review, several animal and human studies are summarized in addition to two Phase III trials assessing the use of intravenous Mg in the treatment of SAH (IMASH and MASH-2). Though many studies have shown promise for the use of Mg in SAH, there has been inconsistency in study design and outcomes. Furthermore, the results of the recently completed clinical trials have shown no significant benefit from using intravenous Mg as adjuvant therapy in the treatment of cerebral vasospasm.

Baseline neurocognitive scores in athletes with attention deficit-spectrum disorders and/or learning disability.

OBJECT: Up to 16% of children in the US between the ages of 3 and 17 years have either attention deficit-spectrum disorder or a learning disability (LD). Sports-related concussions among youth athletes represent a significant public health concern, and neurocognitive testing is a method to evaluate the severity of cognitive impairment and recovery after a sports-related concussion. The goal of this study was to assess baseline neurocognitive differences between athletes with attention deficit hyperactivity disorder (ADHD) and/or LD versus those with neither disorder and to establish normative data for these special populations. METHODS: Between August 2007 and March 2012, 6636 young athletes underwent baseline neurocognitive testing performed using the Immediate Post-Concussion Assessment and Cognitive Testing (ImPACT) battery. Of these participants, 90 had self-reported LD only, 262 had self-reported ADHD only, and 55 reported both. Those with ADHD and/or LD were matched with 407 participants with no history of ADHD or LD by age, sex, and number of prior concussions. The mean scores and SDs were calculated for each group to obtain normative values. A pairwise comparison between each diagnostic group was done to assess whether LD and/or ADHD diagnostic status predicted participants' baseline neurocognitive scores. RESULTS: Participants with ADHD had significantly lower verbal memory, visual memory, and visual motor processing speed scores, along with significantly higher reaction time, impulse control, and symptom scores compared with those without LD or ADHD. Participants with LD had similar results, with significantly lower verbal memory, visual memory, and visual motor processing speed scores, higher reaction time and symptom score, but did not differ in their impulse control score compared with those without LD or ADHD. Participants with both LD and ADHD had a significantly lower visual motor speed score and a significantly higher reaction time and symptom score than those without LD or ADHD, but did not differ with regard to the other composite scores. CONCLUSIONS: Athletes with ADHD and/or LD have lower baseline ImPACT neurocognitive scores compared with athletes without ADHD and LD. Preliminary normative neurocognitive data for these special populations are provided.

Does age affect symptom recovery after sports-related concussion? A study of high school and college athletes.

OBJECT: Sport-related concussions (SRCs) in high school and college athletes represent a significant public health concern. Research suggests that younger athletes fare worse symptomatically than older athletes after an SRC. Using reliable change index (RCI) methodology, the authors conducted a study to determine if there are age-related differences in number, severity, and resolution of postconcussion symptoms. METHODS: Between 2009 and 2011, baseline measures of neurocognitive functions and symptoms in high school and college athletes were entered into a regional database. Seven hundred forty of these athletes later sustained an SRC. Ninety-two athletes in the 13- to 16-year-old group and 92 athletes in the 18- to 22-year-old group were matched for number of prior concussions, sex, biopsychosocial variables, and days to first postconcussion testing and symptom assessment. A nonparametric Mann-Whitney U-test was used to compare the severity of each of 22 symptoms comprising the Total Symptom Scale (TSS) at baseline and first postconcussion test. To obtain a family-wise p value of 0.05 for each test, the significance level for each symptom comparison was set at an alpha of 0.05/22 = 0.0023. The number of days to return to baseline TSS score was compared using the RCI methodology, set at the 80% confidence interval, equal to a change in raw score of 9.18 points on the TSS. RESULTS: There was no statistically significant difference in symptom presence, symptom severity, and total symptoms between the age groups at baseline or at postconcussion testing. There was no statistically significant difference in return to baseline symptom scores between the age groups. CONCLUSIONS: Using RCI methodology, there was no statistically significant difference between younger and older athletes in return to baseline symptoms postconcussion.

Recovery from sports-related concussion: Days to return to neurocognitive baseline in adolescents versus young adults.

BACKGROUND: Sports-related concussions (SRC) among high school and collegiate athletes represent a significant public health concern. The Concussion in Sport Group (CIS) recommended greater caution regarding return to play with children and adolescents. We hypothesized that younger athletes would take longer to return to neurocognitive baseline than older athletes after a SRC. METHODS: Two hundred adolescent and young adult athletes who suffered a SRC were included in our clinical research cohort. Of the total participants, 100 were assigned to the 13-16 year age group and 100 to the 18-22 year age group and were matched on the number of prior concussions. Each participant completed baseline and postconcussion neurocognitive testing using the Immediate Post-Concussion assessment and Cognitive Testing (ImPACT) test battery. Return to baseline was defined operationally as post-concussion neurocognitive and symptom scores being equivalent to baseline using reliable change index (RCI) criteria. For each group, the average number of days to return to cognitive and symptom baseline were calculated. Independent sample t-tests were used to compare the mean number of days to return to baseline. RESULTS: Significant differences were found for days to return to baseline between 13-16 year olds and 18-22 year olds in three out of four neurocognitive measures and on the total symptom score. The average number of days to return to baseline was greater for 13-16 year olds than for 18-22 year olds on the following variables: Verbal memory (7.2 vs. 4.7, P = 0.001), visual memory (7.1 vs. 4.7, P = 0.002), reaction time (7.2 vs. 5.1 P = 0.01), and postconcussion symptom scale (8.1 vs. 6.1, P = 0.026). In both groups, greater than 90% of athletes returned to neurocognitive and symptom baseline within 1 month. CONCLUSIONS: Our results in this clinical research study show that in SRC, athletes 13-16 years old take longer to return to their neurocognitive and symptom baselines than athletes 18-22 years old.
