Synovial lactate is a promising biomarker to distinguish septic from aseptic arthritis. If available as a point-of care test, synovial lactate would be rapidly available to aid the emergency provider in clinical decision making. This study assesses the test characteristics of synovial lactate obtained using an EPOC© point-of-care (POC) analyzer to rapidly distinguish septic from aseptic arthritis in the emergency department. ⋯ It is feasible to obtain a synovial lactate level using the EPOC© POC device. In our study, POC SLL performs similarly to other markers used to diagnose septic arthritis. Further study with larger sample sizes is warranted.

The shock index is a rapid and simple tool used to predict mortality in patients with acute illnesses including sepsis, multiple trauma, and postpartum hemorrhage. However, its ability to predict mortality in geriatric patients with influenza in the emergency department (ED) remains unclear. This study was conducted to clarify this issue. ⋯ A shock index ≥1 has a high specificity, negative predictive value, and good reliability to predict 30-day mortality in geriatric ED patients with influenza.

Compartment syndrome is a potentially limb-threatening disease process, leading to decreased tissue perfusion and cellular death [1]. The following presentation is believed to be the first reported case of thenar compartment syndrome, which occurred without an identifiable cause. A 67-year-old male presented with 12 h of left-hand pain, located at the base of the thumb and worsened with movement. ⋯ The diagnosis was confirmed and successfully managed in the operating room. While relatively uncommon, clinicians should consider the diagnosis of compartment syndrome of the hand when patients present with acute hand pain. A missed or delayed diagnosis can lead to severe morbidity, which can profoundly affect patients' functional outcomes and quality of life.

The definition of myocardial infarction (MI) is based on the detection of high-sensitive cardiac troponin (hs-cTn) levels above the 99th percentile of upper reference limit (URL) value for a healthy reference population. In the era of hs-cTn assay and the 4th definition for MI, the distinction between the injury and infarction is crucial for the clinician. Measurable troponin is present in the blood of healthy adult subjects. ⋯ Professional societies have published their recommendations to solve the pre-analytic and analytic contraversies in hs-cTn assay. In conclusion, hs-cTn assays have revolutionized the practice of cardiology. Universal healthy normal pool and consideration of different cut off levels for different populations (i.e. elderly) can potentially help to standardize the interpretation of the hs-cTn test.

Cranial polyneuropathy is commonly caused by Lyme disease. We discuss the case of a man who presented with cranial nerve deficits causing dysphagia, dysphonia and facial weakness. ⋯ On review, this phenomenon is rarely reported, but has been observed with a number of herpes family viruses. In emergency department settings, clinical suspicion should be raised for VZV infection even in the absence of rash in patients that present with multiple cranial nerve palsies.
