Placental expression of CD100, CD72 and CD45 is dysregulated in human miscarriage.

Context And Objective: The etiology of miscarriage is often multifactorial. One major cause, immunological rejection of the fetus, has not been clearly elucidated. Our aim was to establish whether the semaphorin CD100, its natural receptor CD72, and the glycoprotein CD45, implicated in immune mechanisms, are involved in pregnancy loss by examining their placental expression with real-time PCR, immunohistochemistry and western blotting techniques.

[Descending necrotising mediastinitis: report of two cases].

Descending necrotising mediastinitis is a severe infection spreading from the cervical region to the mediastinal connective tissue. It represents a virulent form of mediastinal infection, requiring prompt diagnosis and treatment to reduce the high mortality associated. An optimal debridement and drainage through an open thoracotomy access are the keys for a successful outcome.
