Switching to Aflibercept in Diabetic Macular Edema Not Responding to Ranibizumab and/or Intravitreal Dexamethasone Implant

PURPOSE To assess short-term functional and anatomical outcomes of refractory diabetic macular edema (DME) following a switch from ranibizumab or dexamethasone to aflibercept. METHODS We included retrospectively eyes with persistent DME after at least 3 ranibizumab and/or one dexamethasone implant intravitreal injections (IVI). The primary endpoint was the mean change in visual acuity (VA) at...

Biological Response to Dental Implant Loading / Overloading. Implant Overloading: Empiricism or Science?

Dental implants have reported success rates of over 90 % over long periods of time. However failures still occur and seem to be unpredictable. One factor that is being increasingly considered in failure of dental implants is occlusal loading. The aim of this article is to review literature related to loading and overloading implants through masticatory and parafunctional activity, in order to a...

Hypersensitivity to Implant Debris

Total Joint Replacements (TJR) have been extremely successful over the past 50 years, restoring mobility and function to millions of people each year. However, over time these implants need replacing for a number of reasons, such as infection or increasing immune reactivity to implant debris. All implant metals degrade in vivo, and the released products biologically interact locally and systemi...

The Cochlear Implant

The studies on cochlear implants have been conducted in the United States, Austria, Brasil, France, Finland, and some other countries. Up to now, this technique does not seem to have a wide spread application. Indeed it can only apply cases of deafness still presenting sufficient neural remnants to transmit the message. Moreover, the patient must be totally deaf( quasi­ complete loss of har cel...
