[Delayed subretinal fluid absorption after rhegmatogenous retinal detachment].

Introduction: Persistent subretinal foveal fluid is responsible for incomplete functional recovery after retinal detachment surgery. The diagnosis may be difficult based on ophtalmoscopy and requires macular optical coherence tomography (OCT).

Case Report: We describe the case of a 25-year-old patient who presented persistence of subretinal foveal fluid over 16 months after an inferior macula off posttraumatic retinal detachment.

Nano-polymer-dispersed liquid crystal as phase modulator for a tunable vertical-cavity surface-emitting laser at 1.55 mum.

We demonstrate what we believe is the first nonmechanical tunable vertical-cavity surface-emitting laser operating in the C band. This was achieved as a result of the combination of an InGaAs quantum well structure with a 6lambda thickness tunable index nano-polymer-dispersed liquid-crystal material. Experimental results exhibited a potential tunable range close to 10 nm, in the preliminary version, and excellent single mode locking due to the side-mode suppression ratio (more than 20 dB) over the whole spectral range.

Prospective assessment of an intervention to rationalize prescribing of nonsteroidal anti-inflammatory drugs.

Guidelines for the prescription of nonsteroidal anti-inflammatory drugs (NSAIDs), drawn in the Health Ministry and published by the Drug Regulatory Agency, were introduced in the emergency department of a university hospital. The main objective was to determine, in this prospective, before-and-after study, whether a teaching program could help doctors improve their NSAID prescribing practices. Correct prescribing included limiting NSAIDs to their most admitted indications, avoiding their prescription to accident-prone patients, and reducing treatment duration and daily dosage.
