Proteus empyema as a rare complication from an infected renal cyst, a case report.

Background: The most commonly isolated organisms in a parapneumonic effusion include S. pneumoniae, H. influenzae, and S.

Assessment of mutational load in biopsy tissue provides additional information about genomic instability to histological classifications of Barrett's esophagus.

Purpose: Progression of Barrett's esophagus (BE) to esophageal adenocarcinoma (EAC) is associated with accumulated genomic instability. Current risk stratification of BE for EAC relies on histological classification and grade of dysplasia. However, histology alone cannot assess the risk of patients with inconsistent or non-dysplastic BE histology.
