Randomized controlled European multicenter trial on the prevention of cystoid macular edema after cataract surgery in diabetics: ESCRS PREMED Study Report 2.

Purpose: To compare the efficacy of perioperative treatment strategies, in addition to topical bromfenac 0.09% and dexamethasone 0.1%, to reduce the risk for developing cystoid macular edema (CME) after uneventful cataract surgery in diabetic patients.

European multicenter trial of the prevention of cystoid macular edema after cataract surgery in nondiabetics: ESCRS PREMED study report 1.

Purpose: To compare the efficacy of a topical nonsteroidal antiinflammatory drug, topical corticosteroid, and a combination of both drugs to prevent the occurrence of cystoid macular edema (CME) after cataract surgery in nondiabetic patients.

Setting: Twelve European study centers.

Design: Randomized clinical trial.

[Fever and exanthema as manifestations of the second stage of syphilis].

A man aged 30 had been suffering from episodes of fever for several weeks. He had diarrhoea and had developed generalized maculopapular exanthema that also affected the palms of his hands and soles of his feet. After viral causes were excluded the symptoms proved to be caused by syphilis.

Corneal transplantation in antibody-deficient hosts.

Purpose: To examine the role of donor-specific antibodies, with or without complement, in rejection of orthotopic corneal transplants by using mice as recipients in which the genes for the heavy chain of immunoglobulin or the third complement component have been eliminated by homologous recombination.

Methods: BALB/c corneas were transplanted into eyes of B-cell-deficient (n=17) or wild-type control C57BL/6 (n=30) mice and into eyes of complement (C3)-deficient (n=15) or wild-type control 129-C57BL/6 (n=13) mice. After surgery all grafts were evaluated over 8 weeks in a masked manner by biomicroscopy for signs of rejection.
