Learning and memory-related brain activity dynamics are altered in systemic lupus erythematosus: a functional magnetic resonance imaging study.

Background: Memory impairment is prevalent in systemic lupus erythematosus (SLE); however, the pathogenesis is unknown.

Methods: We studied 12 patients with SLE without clinically overt neuropsychiatric manifestations and 11 matched healthy controls, aiming to characterize neural correlates of memory impairment, using structural and functional magnetic resonance imaging (MRI). The paradigm consisted of three encoding and free-recall cycles, allowing characterization of dynamics along consecutive retrieval attempts.

Acute calcific band keratopathy: case report and literature review.

Unlabelled: An 86-year-old patient developed a significant intraocular inflammatory reaction after having phacoemulsification. Topical therapy did not eliminate the inflammation, and tissue plasminogen activator (tPA) was injected into the anterior chamber. A white corneal plaque appeared in the previously clear cornea within days of the injection.

"Trap" the diagnosis: a man with recurrent episodes of febrile peritonitis, not just familial Mediterranean fever.

Monogenic periodic fever syndromes are characterized by recurrent episodes of fever, accompanied by localized inflammatory manifestations. Among them, familial Mediterranean fever (FMF) is the most studied and is by far the most prevalent periodic fever syndrome in Israel. We present a diagnostic workup of a patient suffering from a periodic fever syndrome, initially thought to be FMF and characterized by attacks of fever, severe abdominal pain, a migratory erythematous rash and conjunctivitis.

Inside out: a neuro-behavioral signature of free recall dynamics.

Free recall (FR) is a ubiquitous internally-driven retrieval operation that crucially affects our day-to-day life. The neural correlates of FR, however, are not sufficiently understood, partly due to the methodological challenges presented by its emerging property and endogenic nature. Using fMRI and performance measures, the neuro-behavioral correlates of FR were studied in 33 healthy participants who repeatedly encoded and retrieved word-lists.

The perioperative use of biologic agents in patients with rheumatoid arthritis.

Biologic drugs have gained an important place in the treatment of rheumatic diseases. These medications may, however, pose a higher risk of infections in rheumatic patients who a priori are prone to infections. The potential consequences of the immunosuppressive effects of the biologics raise concern about their safety in the perioperative setting.

The findings of the telephone interview were compared with a face-to-face interview and to rheumatologist examination, in 2 separate stages.

Enhanced adhesive properties of endothelial progenitor cells (EPCs) in patients with SLE.

Endothelial progenitor cells (EPCs) are a population of bone marrow-derived cells present in the peripheral circulation, which possess the ability to migrate into areas where angioneogenesis is required and differentiate upon adhesion into mature endothelial cells. EPCs have reparative properties, are able to combat ischemia and have previously been shown to be decreased in level and function in inflammatory conditions. Systemic lupus erythematosus (SLE) is a multi-organ autoimmune inflammatory disorder associated with significantly increased cardiovascular morbidity and mortality.

Simvastatin induces apoptosis of fibroblast-like synoviocytes.

Background: Statins (3-Hydroxy-3-methylglutaryl-CoA reductase inhibitors) exert favorable effects on lipoprotein metabolism, but appeared to possess anti-inflammatory properties among others, as suggested by their ability to inhibit collagen-induced arthritis in mice. Their activity in fibroblast-like synovial cells (FLS) has not yet been studied.

Objectives: To evaluate the effect of varying doses of simvastatin on apoptosis of FLS.
