    Intranasal corticosteroids do not affect intraocular pressure or lens opacity : a systematic review of controlled trials

    No full text
    Background: Intranasal corticosteroids (INCS) are prescribed for the long-term prophylactic treatment of inflammatory upper airway conditions. Although some systemic absorption can occur via topical routes, the clinical relevance is controversial. The effects of orally administered corticosteroids on intraocular pressure (IOP) and lens opacity (LO) are well established, but the impact of the INCS is less well defined. This study aims to systematically review the literature for evidence of adverse occular events with INCS use. Methodology: A systematic review of literature from Medline and Embase databases (January 1974 to 21st of November 2013) was performed. Using the PRISMA guidelines, all controlled clinical trials of patients using INCS, that reported original measures of IOP, LO, glaucoma or cataract incidences were included. Studies with adjuvant administration of oral, inhaled and intravenous steroids were excluded. Results: 665 articles were retrieved with 137 were considered for full-text review. Of these, 116 (85%) were literature reviews and two were case reports. 19 studies (10 RCTs, 1 case-control, 8 case series) were included for the qualitative review, of which 18 reported data on IOP and 10 on cataract/LO. None (n=0) of the 10 RCT reporting data on glaucoma or IOP demonstrated changes in IOP compared to control. Also none (n=0) of the 6 RCTs reporting cataract or lens opacity demonstrated changes compared to control. Conclusion: Data from studies with low levels of bias, do not demonstrate a clinically relevant impact of INCS on neither ocular pressure, glaucoma, lens opacity nor cataract formation.13 page(s

    Systematic review and meta-analysis on outcomes for endoscopic versus external dacryocystorhinostomy

    No full text
    Background: Dacryocystorhinostomy (DCR) is commonly performed for epiphora, dacryocystitis and during tumor surgery. External (EXT-DCR) and endoscopic DCR (END-DCR) are both practiced. END-DCR was initially performed with laser (EL-DCR) but has shifted to careful bone removal with mechanical drills (EM-DCR). High level evidence from comparative cohorts was sought to compare outcomes. Method: Medline (1966 - January 28th, 2013) and Embase (1980 - January 28th, 2013) were searched for comparative studies (RCT/cohorts) of END-DCR to EXT-DCR for acquired nasolacrimal duct (NLD) obstruction. Primary outcome was DCR success, defined as resolution of symptoms and/or patent NLD on irrigation or dacroscintography. Secondary outcomes were scarring, infection and post-operative bleeding. Meta-analysis was performed with the Mantel-Haenszel Method and presented as Risk Ratios (RR) with Confidence Intervals (CI). Results: The search identified 3582 studies and 355 were reviewed after screening. Full text review yielded 19 studies (4 RCTs and 15 cohorts). Overall, EXT-DCR had slightly better success rates than END-DCR (RR 0.96, CI 0.93-1.00). However, EM-DCR outcomes were comparable to EXT-DCR (RR 1.02, CI 0.98-1.06), whereas EL-DCR had poorer outcomes (RR 0.85, CI 0.79-0.91) when compared separately. The RR for scarring, bleeding and infection with END-DCR versus EXT-DCR was 0.07 (CI 0.02-0.22), 0.72 (CI 0.46-1.13) and 0.24 (CI 0.11- 0.54), respectively. The rates of reported revision surgery were similar. Conclusion: DCR is a procedure with high success rates. Endoscopic procedures differ greatly by technique with EM-DCR offering comparable results to EXT-DCR, without the risk of cosmetically unacceptable scars.10 page(s

    Implantation and long-term assessment of the stability and biocompatibility of a novel 98 channel suprachoroidal visual prosthesis in sheep

    Severe visual impairment can result from retinal degenerative diseases such as retinitis pigmentosa, which lead to photoreceptor cell death. These pathologies result in extensive neural and glial remodelling, with survival of excitable retinal neurons that can be electrically stimulated to elicit visual percepts and restore a form of useful vision. The Phoenix99 Bionic Eye is a fully implantable visual prosthesis, designed to stimulate the retina from the suprachoroidal space. In the current study, nine passive devices were implanted in an ovine model from two days to three months. The impact of the intervention and implant stability were assessed using indirect ophthalmoscopy, infrared imaging, and optical coherence tomography to establish the safety profile of the surgery and the device. The biocompatibility of the device was evaluated using histopathological analysis of the tissue surrounding the electrode array, with a focus on the health of the retinal cells required to convey signals to the brain. Appropriate stability of the electrode array was demonstrated, and histological analysis shows that the fibrotic and inflammatory response to the array was mild. Promising evidence of the safety and potential of the Phoenix99 Bionic Eye to restore a sense of vision to the severely visually impaired was obtained

    Assessment of recent process analytical technology (PAT) trends : a multiauthor review

    No full text
    This multiauthor review article aims to bring readers up to date with some of the current trends in the field of process analytical technology (PAT) by summarizing each aspect of the subject (sensor development, PAT based process monitoring and control methods) and presenting applications both in industrial laboratories and in manufacture e.g. at GSK, AstraZeneca and Roche. Furthermore, the paper discusses the PAT paradigm from the regulatory science perspective. Given the multidisciplinary nature of PAT, such an endeavour would be almost impossible for a single author, so the concept of a multiauthor review was born. Each section of the multiauthor review has been written by a single expert or group of experts with the aim to report on its own research results. This paper also serves as a comprehensive source of information on PAT topics for the novice reader
