The evolution and development of a robotic acute care surgery program.

Background: Acute care surgeons perform more than 850,000 operations annually on emergency general surgery patients in the United States. Emergency general surgery conditions are associated with a disproportionate excess of patient complications and death. Innovative quality improvement strategies have focused on addressing the excess morbidity and mortality among this patient population.

Rare Presentations of Rapidly Growing Liposarcomas.

Liposarcomas (LSs) are a rare form of malignant tumors. They are the most common primary neoplasms of the retroperitoneum. While these tumors rarely metastasise, they are characterised by local recurrence and infiltration.

Jejunal Intussusception: A Rare Adult Presentation of Lymphoid Hyperplasia.

A 21-year-old African-American male presented to the emergency room with a sudden diffuse onset abdominal pain of one day duration. CT findings revealed mild telescoping of loops of small bowel and mesenteric fat in the left mid abdomen with no apparent masses. The patient underwent an exploratory laparoscopy revealing intussusception of the mid jejunum.

H-2g, a glucose analog of blood group H antigen, mediates mononuclear cell recruitment via Src and phosphatidylinositol 3-kinase pathways.

Objective: Monocyte recruitment by proinflammatory cytokines is a hallmark of rheumatoid arthritis (RA). Lewis(y-6) and H (Le(y)/H) are blood group antigens up-regulated on RA synovial endothelium. We have previously shown that both soluble Le(y)/H and a glucose analog of H, H-2g, are angiogenic and mediateleukocyte-endothelial adhesion via induction of intercellular adhesion molecule 1.
