Emergency department thoracotomy (EDT) is done to control life threatening hemorrhage and injuries. Literature examining this topic is limited to relatively small studies from single trauma centers. ⋯ Factors associated with survival in patients undergoing EDT were identified. The clinical indication of presence of appropriate resources to continue and repair EDT was validated, along with the contraindications of lack of signs of life and presence of major nonsurvivable injuries. Future studies should focus on validation of all criteria of EDT, namely hemodynamic instability despite appropriate fluid resuscitation, duration of time of cardiopulmonary resuscitation and pulselessness, cardiac rhythm on arrival, and the presence of pericardial tamponade.

Case Reports
Top of Basilar Syndrome Presenting With Hyperekplexia Initially Diagnosed as a Convulsive Status Epilepticus.
Hyperekplexia is a rare neurologic disorder characterized by pronounced startle responses to tactile or acoustic stimuli and increase tone. Acquired hyperekplexia is usually seen in brainstem pathologies and when it develops acutely it can be easily misdiagnosed as a convulsive seizure. ⋯ A 38-year-old man presented with acute onset generalized brief involuntary jerky movements and a decreased level of consciousness. He was initially diagnosed with convulsive status epilepticus for which he received multiple antiseizure medications without any improvement. Further investigations revealed abnormal oculocephalic reflex response and that his movements were in fact hyperkeplexia caused by brainstem infarction with basilar artery thrombus secondary to right vertebral artery dissection. Emergent thrombectomy was performed and he was eventually discharged to a rehabilitation facility. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Emergency physicians should be aware of hyperekplexia and how to differentiate it from convulsive stats epilepticus because the pathology and the emergent treatment of these 2 serious conditions are different. An underlying acquired brainstem pathology (especially basilar artery thromboembolism) should be suspected in any patient with untypical convulsive like movements along with focal neurologic signs compatible with brain stem pathology even when computed tomography imaging is normal. © 2020 Elsevier Inc.

Animals and humans can be readily conditioned to associate a novel stimulus (often a unique taste) by pairing it with the effects of a drug or other agent. When later presented with the stimulus alone, their body's systems respond as if the drug or agent were given. The earliest clinical applications demonstrated both conditioned suppression and enhancement of immune processes. ⋯ The purpose of this analysis was to stimulate research in, and the application of, placebo-response conditioning to emergency medicine. Clinical and experimental studies confirm the usefulness of conditioned placebos in analgesia and in placebo-controlled dose reduction. Such conditioning paradigms demonstrate "one-trial learning," making them potentially useful in pain and addiction management within a single emergency department encounter.

Limited research exists examining the predictors of suicide attempts by mechanism. ⋯ Our findings inform targeted preventative resources and education efforts to populations of greatest need.
