Syphilitic Aortic Aneurysm
Syphilitic aortitis is an inflammatory disease of the aorta associated with the tertiary stage of syphilis infection. SA begins as inflammation of the adventitia (outer layer), including the blood vessels that supply the aorta itself with blood, the vasa vasorum. As SA worsens, the walls of the vasa vasorum thicken, restricting blood flow and causing ischemia of the outer two-thirds of the aortic wall. Starved for oxygen and nutrients, elastic fibres become patchy and smooth muscle cells necrose. The wall weakens and scars. If the disease progresses, syphilitic aortitis leads to an aortic aneurysm.
Pathological subtrochanteric fracture of the femur. Note the lytic medullary lesion with endosteal scalloping at the site of fracture. This patient had multiple myeloma but a metastasis could easily produce the same appearance.

François Robert spent hundreds of hours to create this work of art called Stop The Violence. He bought a human skeleton in the mid 90s during an auction of a former school.
At TEDxYouth@Manchester, genetics researcher Dan Davis introduces the audience to compatibility genes — key players in our immune system’s functioning, and the reason why it’s so difficult to transplant organs from person to person: one’s compatibility genes must match another’s for a transplant to take.
(Images from Davis’s talk, Drew Berry’s animations, and the TED-Ed lessons A needle in countless haystacks: Finding habitable worlds - Ariel Anbar and How we conquered the deadly smallpox virus - Simona Zompi)
So many great speakers and ideas!
