Comparative Study
A comparison of head injuries in male and female lacrosse participants seen in US emergency departments from 2005 to 2016.
In the United States there has been a large increase in participation in lacrosse for both males and females. The purpose of this study was to analyze the number of head injuries, injury rates (calculated using the reported number of participants) and types of head injuries that are seen in emergency departments in the United States. ⋯ The most recent data from 2010 to 2016, suggest that both males and females have had a decrease in injury rate. However the total number of female head injuries is not significantly decreasing and as the sport continues to grow there will likely be more total head injuries and visits to the emergency department.

Observational Study
Risk factors for acute pancreatitis in patients with accidental hypothermia.
Pancreatic damage is commonly observed as a consequence of accidental hypothermia (core body temperature below 35 °C). We aimed to investigate the risk factors for pancreatic damage and the causal relationship in patients with accidental hypothermia. ⋯ We concluded that an initial core body temperature lower than 28.5 °C was a risk factor for acute pancreatitis in accidental hypothermia cases. In such situations, careful follow-up is necessary.

The objective of this study was to evaluate a new multidisciplinary process in which intravenous alteplase (tPA) waste, used for acute ischemic stroke (AIS), was salvaged in an attempt to maximize cost effectiveness without impacting door-to-needle (DTN) administration times. ⋯ Preliminary data, in this pilot study, utilizing a multidisciplinary model for tPA administration led to significant cost savings of tPA and decreases in overall DTN administration times.

Regular, narrow complex tachycardia with a ventricular rate around 150 can be challenging. The differential includes sinus tachycardia, atrioventricular nodal reentrant tachycardia (AVNRT), atrioventricular reentrant tachycardia (AVRT), and atrial tachycardia (focal or macro re-entrant - i.e. flutter). We present a case of a 90-year-old woman presenting with shortness of breath in which the ECG was not diagnostic, but the presence of regular neck pulsations helped secure the diagnosis of AVNRT. ⋯ When the right atrium attempts to contract against a closed tricuspid valve, an abrupt increase in venous pressure is encountered. This increase in venous pressure manifests as prominent neck pulsations termed "cannon A waves." The patient was ultimately successfully electrically cardioverted resulting in resolution of her presenting symptoms, neck pulsations, and tachycardia. While irregular "cannon A waves" can be seen in conditions of AV dissociation, regular "cannon A waves" strongly favor the diagnosis of AVNRT.

Thyrotoxic periodic paralysis (TPP) is a relatively common complication seen in Asian hyperthyroid patients. However, it is a rare occurrence to find a TPP case comprised of acute hypercapnic respiratory failure in patients with painless thyroiditis. ⋯ It is important to note that potentially fatal complications such as acute hypercapnic respiratory failure might occur in acute attacks of TPP even in cases of TPP due to painless thyroiditis.
