Intraocular pressure changes following 20G pars-plana vitrectomy

To observe the excursions of short-term intraocular pressure (IOP) after 20-G pars-plana vitrectomy (ppV).

A pyrosequencing assay for the rapid discrimination of mitochondrial lineages in the Salmo trutta species complex

The European trout (Salmo trutta species complex) is genetically very diverse consisting of five distinct mitochondrial lineages that probably originated in the Pleistocene. Here, we describe a novel pyrosequencing protocol to generate two short sequence reads from the mitochondrial control region, which allow the unambiguous identification of all five lineages. The approach was found to be easily transferable between laboratories and should be a valuable tool for the assessment of genetic diversity in trout. Pyrosequencing-based assays for molecular species identification are expected to be generally useful whenever multiple positions in a short DNA sequence need to be assessed.

Additive effect of homocysteine- and cholesterol-lowering therapy on endothelium-dependent vasodilation in patients with cardiovascular disease

Endothelial dysfunction is a marker for development and progression of atherosclerosis. Statin therapy improves endothelial function in cardiovascular patients by reducing LDL-cholesterol and by pleiotropic effects. B-group vitamin supplementation restores endothelial function mainly by reducing homocysteine-induced oxidative stress. Thus, we evaluated the effect of rosuvastatin, B-group vitamins and their combination on endothelial function in high-risk cardiovascular patients.

Three-year results of visual outcome with disease activity-guided ranibizumab algorithm for the treatment of exudative age-related macular degeneration

PURPOSE To evaluate 3-year follow-up treatment outcomes with ranibizumab (Lucentis(®)) 0.5 mg administered either monthly or quarterly on a pro re nata (PRN) basis according to a disease activity-guided monitoring and treatment algorithm. METHODS A total of 316 treatment-naive eyes of 316 patients with exudative age-related macular degeneration met the criteria for inclusion in this retrospective, interventional case series. Patients were treated with ranibizumab 0.5 mg according to a disease activity-guided algorithm with monthly monitoring. Optical coherence tomography and fluorescein angiography were routinely used to assess disease activity: active lesions were treated with a series of three monthly injections, whereas inactive lesions were treated with quarterly injections. RESULTS Mean Early Treatment Diabetic Retinopathy Study best-corrected visual acuity improved from 52 letters at baseline to 59 letters at 12 months, achieved with a mean of 7.1 injections, 61 letters at 24 months with a mean of 5.0 injections administered in the second year and 60 letters at 36 months with a mean number of 5.2 injections. CONCLUSIONS Monthly visits and a morphology-driven PRN regimen with 3 injections in case of recurrence plus quarterly injections in case of inactive CNV resulted in an average VA gain of 7-9 letters that could be maintained over 3 years.
