Retinal emboli in cholesterol crystal embolism.

Cholesterol crystal embolism (CCE) is a rare and severe multisystemic disorder. It results from a massive release of cholesterol crystals from widespread atherosclerotic disease. The main difference with atherosclerosis is the severity and the quantity of the embolic events that occur during the course of the disease, eventually leading to multivisceral failure and death.

IgA nephropathy associated with ankylosing spondylitis is not controlled by infliximab therapy.

The association between seronegative spondyloarthro- pathies and IgA nephropathy is well documented, mainly in cases of ankylosing spondylitis (AS). However, although these diseases have been associated, the physiopathological links between each other appear unclear. Anti-TNFalpha agents have transformed the outcome of axial forms of AS resistant to conventional anti-inflammatory therapies.

Renal involvement in cystic fibrosis: diseases spectrum and clinical relevance.

Background And Objectives: Clinically relevant kidney involvement is uncommonly described in adult patients with cystic fibrosis (CF). We sought to report on a series of patients with CF and kidney biopsy-documented renal involvement.

Design, Setting, Participants, & Measurements: A retrospective study was undertaken in two referral centers for adult patients with CF in Paris, France.

Psoas abscess: An unusual manifestation of Q fever.

Q fever may lead to serious complications in chronically infected patients. We report two cases of psoas abscess due to Coxiella burnetii associated with lumbar osteomyelitis secondary to an aortic aneurysmal infection. Diagnosis was based on serology, and PCR detected C.
