Background
Ideally, high-stakes examinations assess 1 dimension of medical knowledge to produce precise estimates of a candidate’s performance. It has not been reported whether the American Board of Physical Medicine and Rehabilitation Part 1 Certification Examination (ABPMR-CE-1) is unidimensional or not.Objective
To examine the ABPMR-CE-1 to measure how many dimensions it assesses.Design
Retrospective observational study.Setting
We assessed examination results from the 2015 ABPMR-CE-1.Participants
A total of 489 deidentified candidates taking the 2015 ABPMR-CE-1.Methods
A 1-parameter Item Response Theory (IRT) measurement model was utilized. A Principal Components Analysis (PCA) of standardized residual correlations was used to detect multidimensionality.Main Outcome Measure
Number of primary dimensions reflected in the 325 test questions.Results
The results of the dimensionality analysis indicated that the ABPMR-CE-1 examination is highly unidimensional from a psychometric perspective. Expert content review of the substantive content of small contrasting clusters of questions provided additional assurance of the unidimensional nature of the examination.Conclusions
The ABPMR-CE-1 appears indeed to measure a single construct, which suggests a sound structure of the examination. It closely approximates the assumption of statistical unidimensionality.Level of Evidence

Introduction
As increasing number of patients present to emergency departments with life threatening hemorrhages, particularly intracranial hemorrhage on anticoagulation physicians must be cognizant of the limitations of the available reversal options. Based upon the available literature, our institution formulated a reversal algorithm for patients with life-threatening bleeding on factor Xa inhibitors by administering factor eight inhibitor bypassing agent (FEIBA) 20 units/kg.Methods
A retrospective chart review was performed to include all patients who received FEIBA per institutional protocol. This case series excluded patients who received FEIBA for reversal of dabigatran. Pre and post FEIBA CT scans were compared for changes. Finally, patients were stratified by estimated mortality rates calculated based on pre-intervention characteristics via published risk models.Results
Thirteen patients were initially included in this study yet two patients were excluded because they were on dabigatran. Fifty-five percent of patients demonstrated stable ICH on CT scan after FEIBA administration while thirty-six percent showed worsening scans. Two patients developed thrombotic events after FEIBA administration.Discussion
FEIBA is a treatment option in patients on a TSOA with acute intracranial hemorrhage with evidence of at least partial pharmacologic reversal of their anticoagulation status. There does not appear to be any major risk of thromboembolic complications associated with FEIBA. Much larger study sizes will be necessary to establish statically significant clinical efficacy for FEIBA use in this patient population.Why Should an Emergency Physician Be Aware of This?
Emergency medicine physicians are first-line caretakers for patients with life threatening intracranial hemorrhages whether spontaneous or traumatic. FEIBA is a potentially safe option to reverse TSOA in this patient population. 相似文献3.

Background
A significant proportion of burn injury patients are admitted to inpatient rehabilitation facilities (IRFs). There is increasing interest in the use of functional variables, such as cognition, in predicting IRF outcomes. Cognitive impairment is an important cause of disability in the burn injury population, yet its relationship to IRF outcomes has not been studied.Objective
To assess how cognitive function affects rehabilitation outcomes in the burn injury population.Design
Retrospective study.Setting
Inpatient rehabilitation facilities in the United States.Participants
A total of 5347 adults admitted to an IRF with burn injury between 2002 and 2011.Methods or Interventions
Multivariable regression was used to model rehabilitation outcome measures, using the cognitive domain of the Functional Independence Measure (FIM) instrument as the independent variable and controlling for demographic, medical, and facility covariates.Main Outcome Measurements
FIM total gain, readmission to an acute care setting at any time during inpatient rehabilitation, readmission to an acute care setting in the first 3 days of IRF admission, rate of discharge to the community setting, and length of stay efficiency.Results
Cognitive FIM total at admission was a significant predictor of FIM total gain, length of stay efficiency, and acute readmission at 3 days (P < .05). Cognitive FIM total scores did not have an impact on acute care readmission rate or discharge to the community setting.Conclusions
Cognitive status may be an important predictor of rehabilitation outcomes in the burn injury population. Future work is needed to further examine the impact of specific cognitive interventions on rehabilitation outcomes in this population.Level of Evidence

Background
Stroke is a primary cause of death and disability in upper-middle–income countries such as Colombia. Given the lack of comprehensive rehabilitation for stroke patients in Colombia, there is a need to assess longitudinal mental health problems poststroke in this region.Objective
To compare the course of mental health in stroke patients to healthy controls over the first year poststroke in Ibague, Colombia.Design
Cross-sectional study.Setting
The Psychological Attention Center of Antonio Nariño University in Ibague, Colombia.Participants
Stroke patients (n = 50) and age- and gender-matched healthy controls (n = 50).Methods
Patients and controls completed self-report Spanish versions of demographic information, injury-related characteristics, and mental health questionnairesMain Outcome Measurements
Outcomes assessed included mental health (depression, anxiety, and stress) at 3, 6, and 12 months poststroke.Results
Hierarchical linear models suggested that stroke patients had worse depression and anxiety over time than controls (P < .001). Among patients, depression and anxiety decreased over time (P < .001), whereas stress increased over time (P < .01). The findings suggest that although anxiety and depression improved over time in stroke patients, their mental health remained significantly lower than that of controls.Conclusions
This is the first study to examine the course of mental health over the first year poststroke in Latin America, specifically in Ibague, Colombia. Despite the improvements in anxiety and depression over the first year poststroke, patient anxiety and depression were still worse in comparison to those in healthy controls. The current findings indicate a need for rehabilitation services in Colombia, especially targeting mental health issues.Level of Evidence

Background
Hypermagnesemia is rare and usually iatrogenic. Due to decreased renal function, older patients are generally more susceptible to hypermagnesemia than are younger patients. Because it is not one of the commonly assessed electrolytes in the blood work panel of patients, high levels are usually missed.Case Report
An elderly gentleman with history of leukemia presented with complaints of shortness of breath and extreme weakness while walking. He was diagnosed with severe hypermagnesemia, but unfortunately succumbed to cardiorespiratory arrest.Why Should an Emergency Physician Be Aware of This?
Thorough history taking is crucial in evaluating weakness in elderly patients because the differential diagnosis is vast. Prompt consultation for emergent dialysis is critical to avoiding unfavorable outcomes due to electrolyte abnormalities. 相似文献7.

Background
Osteochondroma is the most common benign tumor of the bone. It is usually asymptomatic, but complications may result from mechanical injury to adjacent anatomic structures, such as the diaphragm and lung, when located intrathoracically.Case Report
We report the unusual occurrence of a large hemothorax and lacerated right diaphragm in a 41-year-old woman caused by vertebral osteochondroma affecting the eleventh thoracic vertebra. Thoracoscopic exploration with resection of the osteochondroma and repair of the diaphragm was performed.Why Should an Emergency Physician Be Aware of This?
Spontaneous hemothorax is a potential life-threatening condition when the initial diagnosis is postponed and hemodynamic instability and hypovolemic shock occurs. Osteochondroma as a cause of spontaneous hemothorax is uncommon but may require urgent surgical intervention with video-assisted thoracoscopic surgery of thoracotomy to control the hemorrhage and prevent recurrence. 相似文献8.
Introduction
Osteopathic Manipulative Treatment (OMT) is effective in improving function, movement and restoring pain conditions. Despite clinical results, the mechanisms of how OMT achieves its' effects remain unclear. The fascial system is described as a tensional network that envelops the human body. Direct or indirect manipulations of the fascial system are a distinctive part of OMT.Objective
This review describes the biological effects of direct and indirect manipulation of the fascial system.Material and methods
Literature search was performed in February 2016 in the electronic databases: Cochrane, Medline, Scopus, Ostmed, Pedro and authors' publications relative to Fascia Research Congress Website.Results
Manipulation of the fascial system seems to interfere with some cellular processes providing various pro-inflammatory and anti-inflammatory cells and molecules.Discussion
Despite growing research in the osteopathic field, biological effects of direct or indirect manipulation of the fascial system are not conclusive.Conclusion
To elevate manual medicine as a primary intervention in clinical settings, it's necessary to clarify how OMT modalities work in order to underpin their clinical efficacies. 相似文献9.
Background
There is a growing interest in the use of biologic agents such as platelet-rich plasma and mesenchymal stem/stromal cells to treat musculoskeletal injuries, including meniscal tears. Although previous research has documented the role of diagnostic ultrasound to evaluate meniscal tears, sonographically guided (SG) techniques to specifically deliver therapeutic agents into the meniscus have not been described.Objective
To describe and validate SG injection techniques for the body and posterior horn of the medial and lateral meniscus.Design
Prospective, cadaveric laboratory investigation.Setting
Academic institution procedural skills laboratory.Subjects
Five unenbalmed cadaveric knee-ankle-foot specimens from 5 donors (3 female and 2 male) ages 33-92 years (mean age 74 years) with body mass indices of 21.1-32.4 kg/m2 (mean 24.1 kg/m2).Methods
A single, experienced operator completed SG injections into the bodies and posterior horns of the medial and lateral menisci of 5 unenbalmed cadaveric knees using colored latex and a 22-gauge, 38-mm needle. After injection, coinvestigators dissected each specimen to assess latex distribution within the menisci and identify injury to intra-articular and periarticular structures.Main Outcome Measures
Latex location within the target region of meniscus (accurate/inaccurate), and iatrogenic injury to “at risk” intra- and periarticular structures (present/absent).Results
Seventeen of 20 injections were accurate. Two of 3 inaccurate injections infiltrated the posterior horn of the medial meniscus instead of the targeted meniscal body. One inaccurate lateral meniscus injection did not contain latex despite sonographically accurate needle placement. No specimen exhibited injury to regional neurovascular structures or intra-articular hyaline cartilage.Conclusions
SG meniscus injections are feasible and can accurately and safely deliver injectates such as regenerative agents into bodies and posterior horns of the medial and lateral menisci. The role of SG intrameniscal injections in the treatment of patients with degenerative and traumatic meniscal disorders warrants further exploration.Level of Evidence

Background
Acute lymphoblastic leukemia (ALL) is the most common form of childhood leukemia. The treatment of ALL involves multimodality therapy, and methotrexate (MTX) remains a mainstay of treatment. A complication of MTX therapy includes acute, subacute, and chronic neurotoxocity. Signs and symptoms may range from headaches, dizziness, and mood disorders to seizures and stroke-like symptoms.Case Report
An 18-year-old woman with a history of ALL presented to the emergency department with acute onset of right-sided facial paralysis, right upper extremity flaccid paralysis, and right lower extremity weakness after receiving MTX therapy 3 days earlier. Diagnostic studies were unremarkable and the patient was treated with oral dextromethorphan for presumed MTX-induced neurotoxicity. The patient's symptoms began to improve within hours and she was discharged home within 48 hours with no neurologic deficits.Why Should an Emergency Physician Be Aware of This?
Emergency physicians should be aware of this complication of MTX therapy given the sensitivity in regards to time with respect to cerebral vascular accidents. An awareness of this complication in the setting of the appropriate history and physical examination can lead to an accurate diagnosis and intervention and the avoidance of administering thrombolytics. 相似文献11.

Background
A suicidal person with a do-not-resuscitate (DNR) order presents an ethical dilemma to the emergency physician. Many believe that suicide is an irrational action, and therefore, all suicide attempts must be treated. Others believe a DNR order should be respected even in the setting of a suicide attempt.Case Report
An elderly woman with a known terminal illness presented to the emergency department after a suspected suicide attempt. She had a DNR order during her previous hospitalization. The emergency physician felt obligated to intubate the woman despite his recognition that she was terminally ill.Discussion
Reasons to both honor and not honor a DNR order after a suicide attempt are reviewed.Conclusion
Not all patients who attempt suicide are necessarily incapable of making a rational decision about their health care. In some cases it may be appropriate to withhold resuscitation attempts in suicidal patients who have a preexisting DNR order. Institutional policies are needed to provide guidance in this situation. 相似文献14.

Background
Oral tyrosine kinase inhibitors (TKIs) are becoming increasingly common in oncology practice due to ease of administration and patient preference. This class of medications is relatively unknown to emergency physicians.Case Report
Here we present a case of electrical storm (ES) thought to be associated with ibrutinib, a TKI. The ES was unabated despite antidysrhythmic therapy and electrical cardioversion, and was treated with supportive care, which eventually included the use of extracorporeal membrane oxygenation. This patient had no risk factors or apparent causes of recurrent ventricular tachycardia.Why Should an Emergency Physician Be Aware of This?
ES has not previously been described with ibrutinib, but may be associated with off-target effects of the drug. 相似文献15.
Background
Insect venom anaphylaxis is a potentially life-threatening disorder. Transient coagulopathy in insect venom anaphylaxis is a rare phenomenon.Case Report
A 41-year-old man presented to the Emergency Department (ED) with hypotension after a run in a park. History and examination revealed signs of anaphylactic shock. A deranged coagulation profile with a normal platelet count led to the diagnosis of wasp sting anaphylaxis.Why Should an Emergency Physician Be Aware of This?
Transient deranged coagulation profile with a normal platelet count may arise from insect venom anaphylaxis. This specific finding may aid the emergency physician in making a diagnosis of anaphylactic shock in an otherwise healthy patient presenting with shock with no apparent cause. 相似文献16.
Background
Pediatric foreign-body ingestions are commonly managed by emergency physicians. Risk assessment and specific intervention are dependent on the nature and location of the foreign body. Radiographic evaluation is usually necessary to help define the clinical situation.Case Report
We present an interesting case of presumed ingestion of several disk batteries by a toddler with an unexpected outcome, reviewing aspects of this clinical problem and highlighting potential pitfalls in medical decision making.Why Should an Emergency Physician Be Aware of This?
Pediatric foreign-body ingestions are commonly managed in the emergency department, and timely and accurate intervention is dependent on correct defining and localization of the foreign body. This case illustrates potential pitfalls in this evaluation. 相似文献17.

Objectives
To examine the effect of experimental knee pain on perceived knee pain and gait patterns and to examine the efficacy of transcutaneous electrical nerve stimulation (TENS) on perceived knee pain and pain-induced knee gait mechanics.Design
Crossover trial.Setting
Biomechanics laboratory.Participants
Recreationally active, individuals without musculoskeletal pain aged 18 to 35 years (N=30).Interventions
Thirty able-bodied individuals were assigned to either a TENS (n=15) or a placebo (n=15) group. All participants completed 3 experimental sessions in a counterbalanced order separated by 2 days: (1) hypertonic saline infusion (5% NaCl); (2) isotonic saline infusion (0.9% NaCl); and (3) control. Each group received sensory electrical stimulation or placebo treatment for 20 minutes, respectively.Main Outcome Measures
Perceived pain was collected every 2 minutes using a 10-cm visual analog scale (VAS) for 50 minutes and analyzed using a mixed model analysis of covariance with repeated measures. Gait analyses were performed at baseline, infusion, and treatment. Sagittal and frontal knee angles and internal net joint torque across the entire stance were analyzed using a functional data analysis approach.Results
Hypertonic saline infusion increased perceived pain (4/10cm on a VAS; P<.05) and altered right knee angle (more flexion and less abduction; P<.05) and internal net joint torque (less extension and greater abduction; P<.05) across various stance phases. TENS treatment reduced perceived pain and improved right sagittal gait abnormalities as compared with placebo treatment (P<.05).Conclusions
This pain model increases perceived pain and induces compensatory gait patterns in a way that indicates potential quadriceps weakness. However, TENS treatment effectively reduces perceived pain and restores pain-induced gait abnormalities in sagittal knee mechanics. 相似文献18.

Objective
To determine whether multifidi size, intramuscular fat, or both, are associated with self-reported and performance-based physical function in older adults with and without chronic low back pain (LBP).Design
Case-control study.Setting
Individuals participated in a standardized evaluation in a clinical laboratory and underwent magnetic resonance imaging (MRI) of the lumbar spine at a nearby facility.Participants
A volunteer sample of community-dwelling older adults (N=106), aged 60 to 85 years, with (n=57) and without (n=49) chronic LBP were included in this secondary data analysis.Intervention
Average right-left L5 multifidi relative (ie, total) cross-sectional area (CSA), muscle-fat infiltration index (MFI) (ie, a measure of intramuscular fat), and relative muscle CSA (rmCSA) (ie, total CSA minus intramuscular fat CSA) were determined from MRIs. Linear regression modeling was performed with physical function measures as the dependent variables. Age, sex, and body mass index were entered as covariates. The main effects of L5 multifidi MFI and rmCSA, as well as their interaction with group assignment, were compared as independent variables.Main Outcome Measures
Medical Outcomes Study 36-Item Short-Form Health Survey physical functioning subscale, timed Up and Go, gait speed, and fast stair descent performance.Results
Interaction terms between L5 multifidi MFI and group assignment were found to be significant contributors to the variance explained in all physical function measures (P≤.012). Neither the main effect nor the interaction with group assignment for L5 multifidi rmCSA significantly contributed to the variance explained in any of the physical function measures (P>.012).Conclusions
Among older adults with chronic LBP of at least moderate intensity, L5 multifidi muscle composition, but not size, may help to explain physical function. 相似文献19.

Objective
To examine how patient satisfaction with care coordination and quality and access to medical care influence functional improvement or deterioration (activity limitation stage transitions), institutionalization, or death among older adults.Design
National representative sample with 2-year follow-up.Setting
Medicare Current Beneficiary Survey from calendar years 2001 to 2008.Participants
Community-dwelling adults (N=23,470) aged ≥65 years followed for 2 years.Interventions
Not applicable.Main Outcome Measures
A multinomial logistic regression model taking into account the complex survey design was used to examine the association between patient satisfaction with care coordination and quality and patient satisfaction with access to medical care and activities of daily living (ADL) stage transitions, institutionalization, or death after 2 years, adjusting for baseline socioeconomics and health-related characteristics.Results
Out of 23,470 Medicare beneficiaries, 14,979 (63.8% weighted) remained stable in ADL stage, 2508 (10.7% weighted) improved, 3210 (13.3% weighted) deteriorated, 582 (2.5% weighted) were institutionalized, and 2281 (9.7% weighted) died. Beneficiaries who were in the top quartile of satisfaction with care coordination and quality were less likely to be institutionalized (adjusted relative risk ratio [RRR], .68; 95% confidence interval [CI], .54–.86). Beneficiaries who were in the top quartile of satisfaction with access to medical care were less likely to functionally deteriorate (adjusted RRR, .87; 95% CI, .79–.97), be institutionalized (adjusted RRR, .72; 95% CI, .56–.92), or die (adjusted RRR, .86; 95% CI, .75–.98).Conclusions
Knowledge of patient satisfaction with medical care and risk of functional deterioration may be helpful for monitoring and addressing disability-related health care disparities and the effect of ongoing policy changes among Medicare beneficiaries. 相似文献20.
