BACKGROUND Current recommendations for ANCA-associated vasculitis (AAV) support its management within a dedicated clinical service. Therapies for AAV are imperfect with many patients failing to achieve disease control and others experiencing disease relapse. Plasma exchange (PEX) may be beneficial especially when the kidney is involved. METHODS Within a new, dedicated service we retrospective...

introduction: pseudoexfoliation syndrome (pex) is the most common identifiable cause of secondary glaucoma, the prevalence of which varies considerably among different ethnicities. the aim of this study was to assess the prevalence of pex in diabetic patients older than 50 years. methods: in this descriptive, cross-sectional study 400 diabetic patients older than 50 years referred to the yazd d...

PEX, a phosphate-regulating gene with homology to endopeptidases on the X chromosome, was recently identified as the candidate gene for X-linked hypophosphatemia. In the present study, we cloned mouse and human Pex/PEX cDNAs encoding part of the 5' untranslated region, the protein coding region, and the entire 3' untranslated region, determined the tissue distribution of Pex/PEX mRNA, and chara...

PURPOSE To test the hypothesis that glaucoma in eyes with pseudoexfoliation (PEX) syndrome results from blockage of the outflow channels by PEX material, melanin granules from the iris pigment epithelium, or both, and to determine the origin of intratrabecular PEX material. METHODS Trabecular meshwork tissue was obtained from five surgically enucleated eyes with PEX glaucoma, ten autopsy eyes...

BACKGROUND/AIM Pseudoexfoliation syndrome (PEX) is an age-related systemic degenerative disorder characterized by the production and progressive accumulation of extracellular fibrillar eosinophilic material in the anterior segment of the eye. The aim of the study was to evaluate several clinical aspects of PEX, such as frequency of PEX and pseudoexfoliation glaucoma (PEXG), intraocular pressure...

OBJECTIVE: Pseudoexfoliation syndrome (PEX) leads to some problems in the eye surgery specially cataract surgery. As the prevalence of eye problems is high in diabetic patients, we meant to assess the prevalence of PEX in diabetic patients. MATERIALS AND METHODS: In this cross-sectional study, 400 type 2 diabetic patients aged 50 or above who referred to Yazd Diabetes Research Center were sele...

Purpose. To compare the macular and peripapillary choroidal thickness in eyes with pseudoexfoliation (PEX) syndrome and PEX glaucoma with the normal eyes of healthy controls. Materials and Methods. In this prospective study, 30 eyes of 30 patients with PEX syndrome, 28 eyes of 28 patients with PEX glaucoma, and 30 eyes of 30 age-matched healthy subjects were enrolled. Choroidal thicknesses in t...
