Deciphering the genetic landscape of Alzheimer disease (AD) is essential to define the pathophysiological pathways involved and to successfully translate genomics to potential tailored medical care. To generate the most complete knowledge of the AD genetics, we developed through the European Alzheimer Disease BioBank (EADB) consortium a discovery meta-analysis of genome-wide association studies (GWAS) based on a new large case-control study and previous GWAS (in total 39,106 clinically diagnosed cases, 46,828 proxy-AD cases and 401,577 controls) with the most promising signals followed-up in independent samples (18,063 cases and 23,207 controls). In addition to 34 known AD loci, we report here the genome-wide significant association of 31 new loci with the risk of AD. Pathway-enrichment analyses strongly indicated the involvement of gene sets related to amyloid and Tau, but also highlighted microglia, in which increased gene expression corresponds to more significant AD risk. In addition, we successfully prioritized candidate genes in the majority of our new loci, with nine being primarily expressed in microglia. Finally, we observed that a polygenic risk score generated from this new genetic landscape was strongly associated with the risk of progression from mild cognitive impairment (MCI) to dementia (4,609 MCI cases of whom 1,532 converted to dementia), independently of age and the APOE e4 allele.

PURPOSE: To report the outcome of LASIK in patients with inactive herpetic keratitis in which perioperative antiviral prophylaxis was used to prevent the recurrence of ocular herpes. METHODS: We report an uncontrolled series of five patients with inactive herpetic keratitis for at least 1 year before surgery in whom LASIK was successfully performed. All patients showed normal topography, pachymetry, and corneal sensitivity with no central corneal scarring. Perioperative prophylaxis was used in each case with oral va !acyclovir and topical acyclovir ointment. RESULTS: None of the eyes developed reactivation of herpetic keratitis during follow-up. CONCLUSIONS: This study suggests that perioperative antiviral prophylaxis may protect the cornea from herpes simplex virus reactivation after LASIK. [J Refract Surg. 2006;22:404-406.]

Topical MMC 0.04% is an option worth considering for the treatment of pigmented conjunctival lesions, particularly as an adjunct to other forms of treatment.
