Differentiation therapy is used in cancer treatment. Epidemiologic studies showed that higher vitamin D levels are associated with reduced cancer risks. However, the therapeutic doses needed for differentiation are accompanied by hypercalcemia and intolerable pathological sequelae. In the present work we evaluated if RRD-251, a small-molecule, can enhance vitamin D3-induced differentiation of l...

PURPOSE To assess the potential role of monocyte chemotactic protein-1 (MCP-1) in the pathogenesis of proliferative vitreoretinopathy (PVR) and to investigate its possible interaction with the macrophage migration inhibitory factor (MIF). METHODS We assayed MCP-1 and MIF levels in the vitreous samples of 85 consecutive patients with PVR (29 eyes), rhegmatogenous retinal detachment (RRD; 22 ey...

Dear Editor, Pars plana vitrectomy (PPV) using the 27-gauge transconjunctival approach is the last frontier of small gauge vitrectomy. Only 1 paper has been published so far describing the use of 27-gauge vitrectomy in a limited number of cases, including epiretinal membranes, idiopathic macular holes, diabetic vitreous haemorrhages, a vitreous biopsy for presumed vitreoretinal lymphoma and a f...

AIM To assess the outcomes of combined 23-gauge sutureless vitrectomy and clear corneal phacoemulsification with intraocular lens implantation for rhegmatogenous retinal detachment (RRD) repair. METHODS This was a retrospective, consecutive, non-comparative, interventional case series of 30 eyes of 30 patients who underwent combined sutureless vitrectomy and clear corneal cataract surgery for...

[Purpose] Force production during a squat action on a rotational resistance device (RRD) under stable and unstable conditions. [Subjects and Methods] Twenty-one healthy males were asked to perform six sets of six repetitions of squats on an RRD on either stable or unstable surfaces. The stable and unstable sets were performed on different days. Muscular outputs were obtained from a linear encod...

The aim of this study is to assess clinical outcomes of 23-gauge vitrectomy and silicone oil (SO) tamponade combined with and without phacoemulsification (PE) in rhegmatogenous retinal detachment (RRD). The study included forty eyes of 40 patients that underwent 23-gauge vitrectomy and SO tamponade combined with and without PE. Twenty eyes of 20 cases, of whom underwent 23-gauge vitrectomy and ...

BACKGROUND To compare scleral buckling (SB) and pars plana vitrectomy (PPV) using a wide angle viewing system (WAVS) for uncomplicated phakic rhegmatogenous retinal detachment (RRD). METHODS The medical records of patients with uncomplicated phakic RRD were retrospectively reviewed. Eyes with pseudophakic or attached fovea were excluded. Patients treated with SB were classified as group B, an...

PURPOSE To determine which factors affect the recovery of visual function in macula off rhegmatogenous retinal detachment (RRD). METHODS In a prospective study of forty-five patients with a primary macula-off RRD of 24 hours to 6 weeks duration, the height of the macular detachment was determined by ultrasonography. At 12 months postoperatively, best corrected visual acuity (BCVA), contrast a...

BACKGROUND The use of hands-on defibrillation (HOD) to reduce interruption of chest compression after cardiac arrest has been suggested as a means of improving resuscitation outcomes. The potential dangers of this strategy in regard to exposing rescuers to electrical energy are still being debated. This study seeks to determine the plausible worst-case energy-transfer scenario that rescuers mig...
