    ABSTRACT: Our goal was to determine whether the combination of tenderness at 1 of 5 commonly fractured sites and elbow extension accurately predicts the presence of acute elbow fractures or isolated effusions in children. A prospective cohort study was performed using a convenience sample of patients. Children 0 to 18 years old with acute elbow injuries without elbow deformities or radial head subluxations were prospectively enrolled. The treating physicians assessed the injured elbow for the presence of tenderness at 5 locations and for abnormal active extension. The examination was defined as positive if any one component was present and negative if all were absent. The radiologist's report or a structured follow-up phone call was used as an a priori-determined composite reference standard for the diagnosis of (1) fracture or isolated effusion and (2) fracture. A total of 332 patients were enrolled; 183 (55.1%) were diagnosed with a fracture (31.0%) or effusion (24.1%). A negative examination result was present in 33 (9.9%), among whom 6 were diagnosed with a small effusion and 1 with a radial neck fracture. The examination's sensitivity, specificity, and positive and negative predictive values (95% confidence interval) were 96.2% (92.0-98.3), 17.4% (11.9-24.7), 58.4% (52.6-64.2), and 60.3% (47.8-72.9), respectively, for fracture or isolated effusion and 99.0% (97.1-100), 14.0% (9.5-18.5), 34.1% (28.7-39.5), and 97.0% (91.1-100.0), respectively, for fracture. A planned subgroup analysis of children younger than 3 years was performed; the elbow extension test was insensitive (sensitivity, 73.3% [51.0-95.7]) at excluding elbow injuries, albeit, when combined with point tenderness, it identified 100% of elbow fractures or effusions. The addition of point tenderness to the elbow extension test is highly sensitive at identifying injuries in children with acute elbow injuries, albeit nonspecific. Although the significance of omitting 10% of radiographs is questionable, a cost-benefit analysis would help clarify its potential savings in terms of expenditure and/or radiation exposure when compared to the risk of missing 2% of children with elbow injuries (albeit mainly small effusions).

    ABSTRACT: Spontaneous intramedullary hematoma(IMH) is a rare condition. The initial clinical manifestations are variable. Early symptoms of high thoracic IMH include thoracocervical pain that can be mistaken for emergent cardiopulmonary conditions such as myocardial infarction, pulmonary embolus, and aortic dissection. We report on a 34-year-old man who presented initially with chest pain, and both shoulder radiating pain. He was initially misdiagnosed with a myocardial infarction and treated with heparin. 2 hours after admission, correct diagnosis of IMH was based on the repeated neurological examination and spine magnetic resonance imaging study. The patient underwent emergency surgical decompression and hematoma removal. We draw the misdiagnosis to the attention of the emergency physicians because early recognition of spontaneous IMH is very important for early surgical decompression to improve the prognosis.

    ABSTRACT: Background The study was designed to investigate the success rate and time of insertion intraosseous access during simulated resuscitation. Material and methods This was a randomised cross-over study involving 107 paramedics. They were timed from start of insertion attempt to successful insertion and asked to score perceived difficulty of intraosseus access devices. BIG, EZ-IO and Jamshidi were used in this study. Results Success rates for first intraosseus iniecition attempt were higher for the BIG (91.59%) than EX-IO (82.66%) or Jamshidi (47.66%). Mean procedure time was 2.0 min ± 0.7 versus 3.1 min ± 0.9 for EZ-IO versus 4.2 min ± 1.0 for Jamshidi. Conclusions The use Bone Injection Gun is associated with excellent success rates for insertion and appears easier to use than EX-IO or Jamashidi Intraosseus Needle. Further work to evaluate to use of the intraosseus access device in the Emergency Medical Services is required.

    ABSTRACT: Intravascular contrast materials are essential to enhance the diagnostic capabilities of medical imaging procedures. Extravasation of contrast is a possible complication of imaging studies performed with contrasts. In this article we present a case of a 60-year-old who was admitted to the Emergency Department with severe pain, swelling and consequently a compartment syndrome of the right hand due to extravasation of contrast material after computed tomography (CT) scan with contrast material to detect the pulmoner thrombo embolism. After the injection of contrast material Compartment Syndrome developed on the dorsum of right hand of the patient and an urgent fasciotomy required. In such cases complications can be reduced by use of non-ionic contrast and careful choice of the site of intravenous administration. After urgent dermato fasciotomy of the hand and fingers full range of motion and sensitivity functions can be restored.

    ABSTRACT: Thrombotic thrombocytopenic purpura (TTP) is a rare medical emergency. The diagnosis of TTP is difficult to establish because this disorder can present without the full pentad of symptoms and often has an subtle onset. Additionally, clinical overlap exists with other diseases. Plasma exchange is the mainstay of treatment and has reduced the mortality rates from over 90% to 10%-20%. Here, we report on a patient with Evans syndrome who presented without microangiopathic hemolytic anemia. The patient developed TTP within two days and quickly died without sufficient time for therapeutic plasma exchange.

    ABSTRACT: Posterior reversible encephalopathy syndrome (PRES), which is commonly encountered in association with various medical conditions including systemic lupus erythematosus (SLE), is an uncommon cause of alteration of consciousness. However, failure to diagnose this condition can lead to permanent neurological deficits. We report a case of 51-year-old woman who presented with altered mental status and was subsequently diagnosed with this syndrome.

    ABSTRACT: Adult-onset Still's disease (AOSD) is a rare systemic disorder, affecting mostly young subjects, particularly women. Myocarditis is rare in adults and it usually presents as myopericarditis. It may cause arrhythmias, heart failure and sudden death, as other myocarditis. The definite diagnosis is only confirmed by endomyocardial biopsy. Our patient had a history of AOSD and consulted to the emergency department with acute heart failure. Ventricular tachycardia, severe left ventricular dysfunction and the lab test made us think of myocardial compromise associated to Adult-onset Still's disease (AOSD) which was finally confirmed by endomyocardial biopsy. We used corticosteroids with favorable response.

    ABSTRACT: Brain hemorrhage is a rare but lethal complication in methanol poisoning. We report a case of massive unilateral intraparenchymatous insular hematoma in a 34 year-old woman with unintentional methanol poisoning. She was admitted to a territorial hospital 72 hours postingestion of an unknown dose of methanol for high anion gap metabolic acidosis and confusion. CT scan showed lesions in putamen and cerebral deep white matter. Sixteen days after methanol exposure, she suddenly developed coma, followed by cardio-respiratory arrest. A second CT scan revealed massive unilateral intraparenchymatous insular hematoma which led to death. Emergency physicians should be aware of this unusual complication of a methanol exposure.

    ABSTRACT: Stroke is the leading cause of acute neurological deficit. However, several potentially life threatening diseases can mimic stroke symptoms. Herein we report 3 cases of sudden onset neurological deficits with a final diagnosis of hyperacute Guillain-Barré syndrome (GBS). Two cases mimicked brain stem stroke while the last suggested a spinal cord infarct. No specific characteristics in terms of electrophysiological parameter, underlying etiology, response to treatment or prognosis was found between these hyperacute forms of hyperacute GBS and more common subacute forms. These cases remind us that acute inflammatory demyelinating neuropathy should always be evoked in front of stroke-like symptoms with negative brain imaging study.
