Diabetic retinopathy (DR) is the leading cause of vision loss in people under 65 years of age. Diabetic macular edema (DME) is the most common cause of moderate visual impairment in individuals with DR. Until recently, focal or grid laser photocoagulation has been the standard of care for DME. Laser photocoagulation has been shown to stabilize vision and prevent moderate vision loss. Recent studies on the effect of anti-vascular endothelial growth factor (VEGF) substances in DME, showed resolution of the edema and visual acuity gain...

BACKGROUND Recent studies identified a set of differentially expressed miRNAs in whole blood that may discriminate neuromyelitis optica spectrum disorders (NMOSD) from relapsing-remitting multiple sclerosis (RRMS). This study invalidated 9 known miRNAs in Chinese patients. MATERIAL AND METHODS The levels of miRNAs in whole blood were assayed in healthy controls (n=20) and patients with NMOSD (n=45), RRMS (n=17) by quantitative real-time polymerase chain reaction (qRT-PCR), and pairwise-compared between groups...

The N-methyl-D-aspartate receptor (NMDAR) is thought to play a key role in the refinement of connectivity in developing neural circuits. Pharmacological blockade or genetic loss-of-function manipulations that prevent NMDAR function during development result in the disorganization of topographic axonal projections. However, because NMDARs contribute to overall glutamatergic neurotransmission, such loss-of-function experiments fail to adequately distinguish between the roles played by NMDARs and neural activity in general...

BACKGROUND: The reference surgical procedure for the treatment of lumbar disc herniation is open microdiscectomy. Minimal invasive discectomy with tubular retractors is hypothesised to cause less tissue damage and result in lower blood loss, less postoperative pain and faster recovery. We previously reported our 1 and 2-year results, and found no better outcomes of tubular discectomy compared with open microdiscectomy. Until now, no studies on tubular discectomy have reported results with more than 2 years of follow-up...

Selective attention enables us to prioritise the processing of relevant over irrelevant information. The model of priority maps with stored attention weights provides a conceptual framework that accounts for the visual prioritisation mechanism of selective attention. According to this model, high attention weights can be assigned to spatial locations, features, or objects. Converging evidence from neuroimaging and neuropsychological studies propose the involvement of thalamic and frontoparietal areas in selective attention...

Besides its role in vision, light impacts physiology and behavior through circadian and direct (aka 'masking') mechanisms. In Smith-Magenis Syndrome (SMS), the dysregulation of both sleep-wake behavior and melatonin production strongly suggest impaired non-visual light perception. We discovered that mice haploinsufficient for the SMS causal gene, Retinoic acid induced-1 (Rai1), were hypersensitive to light such that light eliminated alert and active-wake behaviors, while leaving time-spent-awake unaffected...

Light exerts influences on many physiological and behavioural functions in humans. These functions can be described as image-forming (IF) and non-image forming (NIF) visual processes, both originating in the retina of the eye. Image-forming refers to vision; the process of detecting and distinguishing shapes and colour of objects. Non-image forming refers to detecting level of light intensity or brightness of ambient space, which affects basal physiology such as cycles of rest and activity or the endocrine system...

Chafik Keilani, Samir Abada
Multiple meningiomas growth in patients under cyproterone acetate (CPA) is now well known. However, time between initial CPA intake and diagnosis remains unclear. The exposure time differs in each reported case: from 2 to 10 years. We present the case of an old man with acute visual impairment caused by an unusual bilateral optic nerve compression by three likely planum sphenoidale meningiomas rapidly induced by the admistration of CPA for prostatic adenocarinoma. This case is the first reported with a short exposure time (7 months) to CPA treatment before diagnosis of multiple meningiomas and stabilization on clinical follow-up after CPA treatment discontinuation...

INTRODUCTION: Endometriosis is a chronic inflammatory disease that affects young women in reproductive age. It has mainly three different clinical presentations: superficial (peritoneal), ovarian (endometriomas) and deep endometriosis (DE). The last one is the most advanced form of the disease, frequently impairing fertility and harming women's quality of life. EVIDENCE ACQUISITION: We conducted a systematic review on the surgical treatment of DE in the last ten years focusing on its benefits to improve quality of life (QoL) and for pain relief as well as related surgical complications...

OBJECTIVE: The question whether musical training is associated with enhanced auditory and cognitive abilities in children is of considerable interest. In the present study, we compared children with music training versus those without music training across a range of auditory and cognitive measures, including the ability to detect implicitly statistical regularities in input (statistical learning). METHODS: Statistical learning of regularities embedded in auditory and visual stimuli was measured in musically trained and age-matched untrained children between the ages of 9-11years...

BACKGROUND: Descending pain inhibition suppresses spinal nociception, reducing nociceptive input to the brain. It is modulated by cognitive and emotional processes. In subjects with chronic pain, it is impaired, possibly contributing to pain persistence. A previously developed feedback method trains subjects to activate their descending inhibition. Participants are trained to use cognitive-emotional strategies to reduce their spinal nociception, as quantified by the nociceptive flexor reflex (RIII reflex), under visual feedback about their RIII reflex size...

All contact lenses (corrective/noncorrective) are considered Class II or Class III medical devices under the Federal Food, Drug, and Cosmetic Act, which also states that contact lenses can only be obtained with a prescription. The Forensic Chemistry Center of the US Food & Drug Administration has examined over 300 decorative, noncorrective contact lenses obtained without a prescription. Our observations indicate that 60% of the counterfeit lenses and 27% of the unapproved lenses examined were positive for microbial contamination...
