Troponin Limit of Detection Plus Cardiac Risk Stratification Scores to Rule Out Acute Myocardial Infarction and 30-Day Major Adverse Cardiac Events in ED Patients.

When screening for acute myocardial infarction (AMI), troponin levels below the 99th percentile, including those below the limit of detection (LOD), are considered normal. We hypothesized that a low-risk HEART score (0-3) or ACS Pretest Probability Assessment <2% plus a single troponin below the LOD would rule out both AMI and 30-day major adverse cardiac events (MACE). We studied all patients who presented to a single academic emergency department and received a troponin I (Siemens Ultra Troponin I) from September 1, 2013, to November 13, 2013 (n=888).

Diffuse periventricular calcification and brain atrophy: A case of neonatal central nervous system cytomegalovirus infection.

TORCH refers to the most common congenitally acquired infections: toxoplasma, rubella, cytomegalovirus, and herpes simplex virus. Neonatal cytomegalovirus infection remains a common cause of congenital infection worldwide with effects ranging from hearing impairment to significant neurological morbidity. We report a case of a term neonate with ventriculomegaly on prenatal ultrasound who presented with low birth weight, small head circumference, hepatosplenomegaly, and purpuric rash on physical exam.
