Coeliac artery avulsion secondary to high velocity blunt abdominal trauma: a case report.

Coeliac artery (CA) injuries are an extremely rare subset of blunt abdominal trauma with a reported incidence of only 0.01%. Patterns of CA injury include intimal tear, dissection, thrombosis and pseudoaneurysm, with the most rare being complete CA avulsion.

True Saccular Aneurysm at the Iliac Bifurcation in an Adolescent: Case Report and Review of Lower Limb Vascular Embryology.

Introduction: Isolated iliac artery aneurysms are an uncommon occurrence in the absence of concurrent aortic disease in the adult population and are a rare entity in children and adolescents. Paediatric patients may present with false aneurysms less frequently but true aneurysms are exceptional. In this report, the case of an iliac bifurcation true saccular aneurysm is described.

WSES position paper on vascular emergency surgery.

Trauma, both blunt and penetrating, is extremely common worldwide, as trauma to major vessels. The management of these patients requires specialized surgical skills and techniques of the trauma surgeon. Furthermore few other surgical emergencies require immediate diagnosis and treatment like a ruptured abdominal aortic aneurysm (rAAA).

LIGHT contributes to early but not late control of Mycobacterium tuberculosis infection.

The TNF superfamily member, LIGHT, contributes to optimal T-cell activation in vitro through co-stimulation of dendritic cell cytokine production; however, its role in T-cell-mediated control of intracellular bacterial infections is unknown. Protective immunity against Listeria monocytogenes and Mycobacterium tuberculosis infection requires both antigen-specific CD4(+) and CD8(+) T cells. Using LIGHT-deficient mice we determined that LIGHT was necessary for optimal re-stimulation of anti-listerial CD8(+) T cells in vitro.

Differential requirements for soluble and transmembrane tumor necrosis factor in the immunological control of primary and secondary Listeria monocytogenes infection.

The relative contributions of transmembrane tumor necrosis factor (memTNF) and soluble tumor necrosis factor (solTNF) in innate and adaptive immunity are poorly defined. We examined the capacities of wild-type (WT) mice, TNF-/- mice, and memTNF mice, which express only transmembrane TNF, to control primary and secondary Listeria monocytogenes infections. Soluble TNF was not required for induction or maintenance of protective immunity against a low-dose (200-CFU) Listeria infection.
