The Novel Role of the Expression of Toll-like Receptors TLR-5, TLR-6, and TLR-9 and Associated Up-Regulation of Programmed Cell Death 1 Receptor (PD-1) and Its Ligand (PD-L1) in Lung Sepsis.

Sepsis is a leading cause of death in hospitalized patients. The underlying pathophysiologic mechanisms of sepsis have not been fully elucidated thus far. The receptor of programmed cell death 1 (PD-1) and its ligand (PD-L1), in combination with the Toll-like receptors (TLRs), seem to contribute considerably in systematic responses during sepsis.

Pseudoaneurysm of the Superior Lateral Genicular Artery of the Knee Following Arthroscopic Irrigation and Debridement and Review of Literature.

Knee arthroscopy is among the most popular surgical procedures performed worldwide. Following knee arthroscopy, complications are infrequent, with vascular damage being extremely rare. We present a case of a 16-year-old man with a superior lateral genicular artery pseudoaneurysm of his right knee.
