Multicenter Study
Patterns of facial trauma before and after legalization of marijuana in Denver, Colorado: A joint study between two Denver hospitals.
The effect of marijuana on human health has been studied extensively. Marijuana intoxication has been shown to affect performance, attention span, and reaction time. The public health relationship between trauma and cannabis use has also been studied, with mixed conclusions. In this report, the effect of marijuana legalization on many aspects of facial trauma at two hospitals in Denver, Colorado is examined. ⋯ Public health efforts should be directed towards educating residents and visitors of Colorado on the effects and toxicology of marijuana. More epidemiologic studies are needed for further assessment of the long-term effects of the legalization of marijuana on the population.

Glucocorticosteroids (GCS) are known to cause the hematologic effect of leukocytosis and neutrophilia. Leukocytosis is a key parameter in establishing the diagnosis of sepsis and in the estimation of its severity. ⋯ In patients with acute infections chronically treated with GCS, an increase in the WBC is at average of 5×109/L. These data must be taken into consideration while using the level of leukocytosis as a parameter in the diagnosis of the infectious process.

Metformin-Induced Lactic Acidosis (MILA): A case report and review of current diagnostic paradigm.
A new diagnostic paradigm has been proposed to better categorize causes of Metformin-Associated Lactic Acidosis (MALA). The diagnostic criteria defines a link between Metformin and lactic acidosis if lactate is >5mmol/L, Ph<7.35 and Metformin assay >5mg/L. Metformin assays are not readily available in emergency departments including nationwide Veteran's Affairs Hospitals; thereby making this proposed classification tool difficult to use in today's clinical practice. ⋯ According to the new criterion, our case would be classified as "Lactic Acidosis in Metformin-Treated Patients (LAMT)." However, the term LAMT does not distinguish between a septic patient taking Metformin with lactic acidosis, and a patient who ingested toxic amounts of Metformin and has lactic acidosis (in absence of Metformin assay). Our case highlights the importance of medication reconciliation done on arrival to emergency department. Timing and dosing of Metformin in patients who present to the emergency department with lactic acidosis may cinch the diagnosis of Metformin-Induced Lactic Acidosis (MILA) in the absence of a Metformin assay but in the right clinical context.

Case Reports
Dynamic variations in platelet counts may reflect the severity and prognosis of stingray injuries in the early phase.
There is often a delay in offering quality and prompt treatment after a stingray sting. We present 3 cases of stings and discuss the Poisoning Severity Score (PSS) and a simple tool to assess the severity of such injuries. A 34-year-old man, who worked as an aquarium keeper, presented a wound on the left fifth digit caused by a stingray. ⋯ We found that relatively high PSSs were associated with lower platelet counts that happen due to various adverse events. We suggest that dynamic changes in platelet counts may be associated with the severity of the injury. Furthermore, lower platelet counts in the normal or abnormal range may indicate poor prognoses.

There is significant overlap between the symptoms of patients presenting with retinal detachment (RD) and posterior vitreous detachment (PVD). Urgency to obtain consultation and treatment are dependent on the ability to accurately distinguish these two conditions. The objective of this study was to determine the ability of emergency physicians to differentiate RDs from PVDs using point-of-care (POC) ocular ultrasound. ⋯ Emergency physicians were modestly accurate in distinguishing RD from PVD on POC ultrasound.
