Hematuria by urine dipstick with absent red blood cells (RBCs) on microscopy is indicative of rhabdomyolysis. We determined the sensitivity of this classic urinalysis (UA) finding in the diagnosis of rhabdomyolysis. ⋯ The combination of a positive urine dip for blood and negative microscopy is an insensitive test for rhabdomyolysis, and the absence of this finding should not be used to exclude the diagnosis.

Hypokalemia is a common biochemical abnormality. Severe hypokalemia can produce cardiac rhythm alterations and neurologic manifestations. ⋯ Electrocardiographic alterations and neurologic manifestations completely disappeared after potassium replacement; however, prolonged potassium supplementation was required to achieve the normalization of plasmatic potassium levels. Consecutive figures show ECG improvement until normalization of ECG findings.

Methicillin-resistant Staphylococcus aureus (MRSA) infections are becoming increasingly prevalent in both community and hospital settings. Certain strains are notorious for causing skin and soft tissue infections in patients with no established risk factors. In this article, we report our findings on the dynamic antibiotic resistance pattern of MRSA and outpatient prescription trend for skin and soft tissue infections within our community. ⋯ Methicillin-resistant Staphylococcus aureus is a particularly virulent, rapidly adaptive pathogen that is becoming increasingly difficult to combat with existing antibiotics. Care must be taken to ensure appropriate treatment and follow-up of patients with known MRSA infections.

Emergency department (ED) wait times have continued to worsen despite receiving considerable attention for more than 2 decades and despite the availability of a variety of methods to restructure care in a more streamlined fashion. This article offers an economic framework that abstracts away from the details of operations research to understand the fundamental disincentives to improving wait times. Hospitals that reduce wait times are financially penalized if they must provide more uncompensated care as a result. ⋯ We find that the likely effect of the Patient Protection and Affordable Care Act's insurance expansion is to reduce this penalty for improving ED wait times. Consequently, mandating adoption of solutions to ED crowding may be unnecessary and counterproductive. If the insurance expansion is insufficient to fully solve the problem, the hospital value-based purchasing initiative should adopt wait times as a goal in its next iteration.
