ABSTRACT

The authors present a case of a 51-year-old female who presented to the emergency department with general malaise, headache, neck stiffness, and an expanding rash consistent with Lyme neuroborreliosis. In this case report, the clinical presentation, diagnosis, and management of Lyme neuroborreliosis and different presentations of erythema migrans are discussed.

ABSTRACT

This study examines the accuracy of initial and subsequent serum procalcitonin (PCT) levels in predicting positive blood cultures, in-hospital mortality, and development of septic shock in emergency department (ED) patients with severe sepsis. This study includes all patients who presented to our ED with an admission diagnosis of severe sepsis over a period of nine months. The median initial PCT was 0.58 ng/mL, interquartile range (IQR) 0.16-5.39. The median subsequent serum PCT was 2.1 ng/mL, with an IQR of 0.3-11.1. The PCT trend over the initial three hours increased in 67% of the study population. Blood cultures were positive in 38% of the cohort. The median maximum PCT in those with a negative blood culture was 1.06 ng/mL compared to 4.19 ng/mL in those with a positive blood culture (p=0.0116). Serum PCT levels >2.0 ng/mL display significant correlation with positive blood cultures, in-hospital mortality, and development of septic shock and as such may serve as a biomarker for more serious infections.

ABSTRACT

Aortic dissection is a well-known, but relatively uncommon diagnosis in the emergency department (ED). With a mortality rate as high as 30 percent, it is important to be able to diagnose quickly and accurately. Definitive diagnosis with imaging studies such as computed tomography angiogram (CTA) can be expensive and time-consuming and may not always be available in the community. Herein, we discuss a case of a 59-year-old man presenting with severe chest pain, hypotension, and bradycardia who was diagnosed with aortic dissection first by bedside ultrasound. This expedited the CTA and a cardiothoracic surgery consult, leading to a successful emergent aortic repair.
