RESUMO
BACKGROUND: recently much studies evidenced the potential role of photo-biomodulation (PBM) in patients affected by Age-related Macular Degeneration (AMD). We designed a new wearable device for self-medication that employs the same broadband red light described in literature, but with extremely low irradiance. AIM: to demonstrate the safety and effectiveness of low-fluence light stimulations emitted by a LED source with appropriate wavelengths through our new device in improving short-term visual function in patients affected by severe non neovascular AMD. MATERIALS AND METHODS: we prospectively enrolled patients affected by severe non-neovascular AMD with a relative sparing of the foveal region. All the patients were randomly assigned in placebo or in treatment group. The treatment consisted of 10 sessions of 10-min each, using the new device comprised of micro-LEDs that emitted light onto an amorphous support assembled within Metallic eyeglasses. The placebo group blindly underwent the same number of PBM sessions with the micro-LED turned off. Before and after each placebo/treatment sessions all the patients received: optical coherence tomography (OCT), Best-Corrected Visual Acuity (BCVA) and Microperimetry (MP). RESULTS: no significant differences in the anatomical parameters were observed in the two groups. The MP mean sensitivity and the central visual function both far and near significantly improved in the treated group (respectively p < 0.001, p < 0.001). CONCLUSIONS: our pivotal demonstrated that the LED PBM delivered through our new device is a safe and effective tool for improving short-term visual function in patients affected by severe non-neovascular AMD.
RESUMO
The biological history of Chlamydia trachomatis is intertwined with the evolution of the man. Infecting Elemental Bodies (EBs), having penetrated mucosal epithelial cells, wrap themselves in a cloak (ĸλαµÎ¹ς) of glycogen that ensures their obligatory intracellular survival and protects this differentiation into Reticulate Bodies (RBs) that feed on cellular ATP. Multiple chemokines and cytokines are involved under the direction of IL-6 in the florid phase and IL-17A in the scar phase. The WHO has successfully identified the SAFE strategy against trachoma (Surgery, Antibiotics, Facial cleansing, Environment) as the blueprint to eliminate the disease by 2020. Recently, interest has been increasingly focused on changing sexual attitudes in different areas of the world, leaving Musca sorbens, Scatophaga stercoraria, and stepsisters fairly blameless, but extolling the role of Chlamydia trachomatis in apparently "sterile" chronic prostatitis or conjunctivitis or, less frequently, in oropharyngitis and proctitis. The addition of an S (SAFE-S) standing for "sexual behavior" was then proposed to also attract the interest and attention not only of Ophthalmologists and Obstetricians/Gynecologists, Urologists/Andrologists, and the School Authorities for information on the prevention of sexually transmitted diseases, but also of Social Physicians and Pediatricians. This means that sexually transmitted infections should be screened in asymptomatic patients with risky sexual behavior or sexual contact with people diagnosed with a transmitted infection.
