BACKGROUND Calcific uremic arteriolopathy is an uncommon cutaneous ischemic necrotizing disease, most commonly associated with renal disease and hyperparathyroidism, bearing a high mortality rate. OBJECTIVE AND METHOD A case of a 57-year-old female renal patient with hyperparathyroidism who was successfully treated with combined paricalcitol and(More)
Vascular access (VA) survival is a crucial issue associated with morbidity and mortality of patients undergoing maintenance hemodialysis. The development of stenosis is the major factor that leads to VA failure. Strategies for early detection of lesions within a VA system before serious complications arise are therefore crucial. The implementation of a VA(More)
PURPOSE To evaluate the functional and cosmetic results after frontalis sling repair for unilateral ptosis associated with either poor levator function or synkinesis. METHODS Preoperative and postoperative photographs and records of 127 patients who underwent unilateral frontalis sling ptosis repair were retrospectively reviewed. An eyelid crease incision(More)
Orbital melanomas comprise a heterogeneous group of pigmented tumours originating from melanocytes of the ophthalmic tissues, or represent distant metastases of cutaneous melanomas to the orbit. They can be classified into primary and secondary orbital melanomas. Whereas primary orbital melanomas are extremely rare, secondary orbital melanomas are seen more(More)
BACKGROUND Hemodiafiltration with online preparation of the substitution [online high-flux hemodiafiltration (OHDF)] and hemodiafiltration with prepared bags of substitution (HDF) are important, recently widely used renal replacement therapies in patients with end-stage renal disease. However, there is little information on the comparative impacts of these(More)
AIMS We sought to determine the association between levels of adiponectin and oxidized low-density lipoprotein (ox-LDL) in patients with diabetic nephropathy as well as their effect on carotid intima-media thickness (cIMT). METHODS Adiponectin and ox-LDL were determined in 25 diabetic patients without nephropathy and 94 patients at different stages of(More)
AIMS We sought to determine the predictive value of Matrix Gla Protein MGP T-138C polymorphism in relation to all-cause mortality, cardiovascular mortality and cardiovascular events in patients with diabetic nephropathy (DN). METHODS MGP T-138C polymorphism was assessed in 40 diabetic patients without nephropathy and 118 patients at different stages of(More)
BACKGROUND The systemic effects of absorbed glucose degradation products (GDPs) contained within the conventional peritoneal dialysis solutions (cPDS) are largely unknown, while they appear to affect also cardiovascular function. The aim of the present study was to evaluate if the new bicarbonate-based less bioincompatible new peritoneal dialysis solutions(More)
