Caffeine (1,3,7-trimethylxanthine) is a naturally occurring compound found in plants and is the most utilized drug in the world. An estimated 89% of U.S. citizens and 80% of people worldwide consume caffeine on a regular basis. The prevalence of caffeine supplementation by individuals has been increasing in body-weight regulation (e.g., weight loss, body building). Immunology activator When used in excessive amounts it can precipitate serious health consequences, including death. Given this, and the ease of accessibility, caffeine has been seen in intentional overdose. However, suicide attempts via caffeine overdose are rare. In 2017, the American Association of Poison Control Centers reported 3765 cases of caffeine overdose, of which 650 were intentional and none resulted in death from caffeine alone. An ingestion of 5g (80-100mg/kg) is likely to prove fatal. We present the case of a suicide attempt via caffeine with a reported 20-g overdose, which would be an estimated blood caffeine level of 427.1mg/L. The patient was givetivated charcoal and treated for symptomatic tachycardia and diaphoresis. He was ultimately evaluated by Psychiatry and was discharged home with no adverse outcomes from his intentional overdose. We also examine the physiology of the potential adverse effects of caffeine use and the current literature related to caffeine overdoses. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Caffeine is consumed by billions of individuals globally. It is rarely associated with death, but can cause a variety of adverse effects including tachydysrhythmias, hypokalemia, seizures, and rhabdomyolysis. Caffeine overdoses should be treated immediately with activated charcoal if within the appropriate timeframe of 1-2 h post-ingestion, and special attention should be given to the cardiovascular effects of caffeine, as tachydysrhythmias may prove fatal. Electrical injuries are common in daily life. The severity of electrical injury depends on the electric current, and assessing electrical damage is difficult because there appears to be no correlation between skin burns and visceral injury. We report a case of bilateral lung injury with pulmonary hemorrhage after exposure to low-voltage electricity. A 23-year-old man was shocked by a low-voltage (110V) electric current while at work. He had temporary loss of consciousness and twitching in the extremities, but soon regained consciousness and spontaneously stopped twitching. Electrical burn wounds were discovered on his back and forehead. Dyspnea and hemoptysis were noted. A computed tomography scan of the chest revealed patchy infiltration and consolidation of both lungs. The patient received treatment of tranexamic acid and prophylactic antibiotics for electricity-induced lung injury and pulmonary hemorrhage. Resolution of chest radiograph abnormalities was recorded on day 7. The mild dyspnea ceased approimately 2 weeks later. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS? Electricity-induced lung injury should be considered in patients with electrical injury through a suspicious electrical current transmission pathway, respiratory symptoms, and corresponding imaging findings. Pulmonary complications can be serious and require early intervention. For 20years, telemedicine has been waiting in the wings for its time in the spotlight. The Coronavirus Disease 2019 (COVID-19) pandemic, with its emphasis on personal protective equipment (PPE) and reducing high-risk contacts, was the catalyst needed to bring telemedicine into mainstream consciousness and acceptance. We first review some of the key factors that precipitated this abrupt alteration of the perception of telemedicine. We then detail the creation of a department-wide telemedicine network using off-the-shelf consumer products. Our goal was to very rapidly install a system that was familiar to end-users for the purpose of reducing high-risk contacts and conserving PPE. Sourcing from the consumer realm proved to be advantageous over enterprise-level equipment when these goals were desired. After a rollout of 1.5weeks from zero to fully operational, we showed an immediate decrease in high-risk contacts and PPE use. All 80 rooms plus all triage areas in our department were outfitted with Apple iPads running Zoom. User adoption was high and telemedicine use increased from ∼17 to ∼90 instances a day, a 429% increase. We saw a decrease in high-risk contacts of about 75%, with a concomitant cost savings in PPE. We propose that the use of consumer products sourced from local vendors is a viable solution for telemedicine systems focusing on speed, reducing costs, and ease of deployment. Future work will focus on studying its performance characteristics vs. other systems in an evolving landscape.We propose that the use of consumer products sourced from local vendors is a viable solution for telemedicine systems focusing on speed, reducing costs, and ease of deployment.

The reduction of shoulder dislocation requires adequate procedural sedation and analgesia. The mixture of midazolam and fentanyl is reported in the literature, but long-acting benzodiazepines in conjunction with fentanyl are lacking. Our aim was to compar e IV diazepam with IV midazolam in moderate procedural sedation (based on the classification of the American Society of Anesthesiologists) for the reduction of shoulder dislocation. This was a randomized controlled clinical trial conducted from April 2019 to December 2019 in the emergency department of a university-affiliated hospital in Tehran, Iran. Participants were adult patients (aged 18-65years) with anterior shoulder dislocation. Group A (n=42) received diazepam 0.1mg/kg plus fentanyl 1μg/kg IV and group B received midazolam 0.1mg/kg plus fentanyl 1μgg/kg IV. Main outcomes measured were onset of muscle relaxation, time taken to reduction, total procedure time, number of the reduction attempts, patient recovery time, the occurrence of the adversescle relaxation, patient and physician satisfaction, and time taken to reduction.
