Viral Myositis in an Eight-Year-Old.

Benign acute childhood myositis (BACM) is a pediatric syndrome characterized by mild self-limiting sudden onset of muscle pain during or following recovery from a viral illness. The case discussed in this report is of an eight-year-old female diagnosed with the common cold after presenting to her primary care physician. Five days later, the patient presented to the emergency department with lower extremity pain. The patient was sent home with supportive care and mild analgesics. Twelve hours later, the patient was seen again in the emergency department with severe bilateral lower extremities pain and difficulty walking. BACM most commonly affects school-age children and is usually caused by influenza A and B. The main goal of this case report is to help primary care and emergency medicine physicians diagnose benign acute childhood myositis as early as possible and treat the condition appropriately.

Congenital anomaly of coronary artery: absence of left circumflex artery.

The prevalence of congenital coronary artery anomalies is approximately 1% in the general population. They are a common cause of sudden death in younger persons. Congenital absence of the left circumflex artery is usually a benign condition but can cause symptoms of exertional angina. We present a case of a 59-year-old female who presented with complaints of chest pain. She was evaluated by the cardiology service. An invasive angiogram identified the absence of the circumflex artery, a large right coronary artery, and large septal and diagonal branches of the left main coronary artery possibly as a compensatory mechanism to supply blood to the LCx territories. It is important to define coronary anatomy as anomalies dictate which cardiac intervention should be attempted in cases of ischemia.
