    Since 2004 applications for research funding in ophthalmology have been evaluated together with those from neurosurgery, neuropathology, psychiatry, psychotherapy, psychosomatics, otolaryngology and neurology by a joint review board of the German Research Council (DFG). Facing a decreasing number of applications--in contrast to the need and importance of widespread ocular diseases--the working group "young academics" of the Deutsche Ophthalmologische Gesellschaft (DOG) assessed the perception of funding programmes and grants available. Young ophthalmologists think that they have poor prospects to receive funding by a DFG proposal. In comparison, specialist funding quotas show a stable development within the neurosciences over the last years. The sum of requested funding has a strong correlation with the total amount actually paid. By clarifying the number of funded proposals, the better transparency and communication for the existing programmes should improve the cooperativeness, the funding rate and number of applications in future. This inventory explicitly includes a motivational guidance for young researchers to take the initiative to do more proposals. Georg Thieme Verlag KG Stuttgart · New York.

    Experimental basic research provides the foundations for the elucidation of pathophysiological mechanisms of diseases and the development of novel diagnostic and therapeutic strategies for ophthalmological diseases. The objective of this contribution is to provide an overview of the international interconnection of basic research in ophthalmology in Germany. The international context of ophthalmological research conducted in Germany is presented by means of personal experiences and data published by the German Ophthalmological Society (DOG), the German Research Foundation (DFG) and the European Union (EU). Due to the lack of organized databases this article lays no claim to completeness. Basic research in ophthalmology in Germany is mainly conducted in university eye departments and is mainly related to the etiology, pathophysiology and therapy development for various ophthalmic diseases. It is primarily funded by the DFG, the Federal Ministry of Education and Research (BMBF) and the EU plays an increasingly important role. Thus, ophthalmological research is integrated into numerous European research networks and beyond that into many international interconnections and relationships. In Germany, both clinical and basic research in ophthalmology is integrated into many international networks and is only functionally viable in an international context; however, given the increasing impact of ophthalmological research in Asian countries, future strategies require a continued focus on career development, research infrastructure, working environment and international cooperation.

    Wood - the fuel source of the past - is expected to be a fuel source of the future. Fast growing trees are being cloned and nurtured for conversion to biofuels to replace or supplement gasoline for transportation. The future may also bring higher temperatures and drought if global climate changes as predicted. So, it seems practical to raise fastgrowing trees that not only provide fuel by capturing carbon from the atmosphere (helping to deter climate change) but also flourish under dry conditions. A recent ORNL finding has bearing on this goal. Hybrid willow trees have been cloned because they grow fast and serve as good fuel sources. However, there are important gender differences. Male willow clones are generally more tolerant of drought than female willows. Also, male willows cause no weed problems because they do not disperse seeds. In addition research work has looked at the impact of enhanced carbon dioxide environments on the growth of trees and the potential sequestering of carbon dioxide into the trees or soils. Scientists have found that ground-level ozone in the environment can reduce the growth of the loblolly pine, a forest tree species of great economic importance in the Southeast. It is predicted that global warming could lead to changes in regional precipitation, even periods of drought. How would climate change affect the growth of forest trees? This is a question ORNL has been attempting to answer. Geologic records have been studied by means of isotope ratio techniques to study reasons for vegetation changes in the past. The question is what was the reason for these changes.

    To assess whether scholarly impact of academic ophthalmologists, as measured using the h-index, is affected by fellowship training status and to further characterize differences in productivity among the various subspecialties and by departmental rank. A descriptive and correlational design was used. In total, 1440 academic ophthalmologists from 99 ophthalmology training programs were analyzed. The h-index data were obtained from the Scopus database. Faculty members were classified by academic rank and grouped into 10 categories based on fellowship training: anterior segment, corneal and external disease, glaucoma, uveitis and ocular immunology, vitreoretinal disease, ophthalmic plastic surgery, pediatric ophthalmology, neuro-ophthalmology, ophthalmic pathology, and "other." A one-way analysis of variance or Student t test using Microsoft Excel and "R" statistical software were used for comparison of continuous variables, with significance set at p < 0.05. Faculty working in academic ophthalmology residency training programs in the United States whose information is stored in the American Medical Association's Fellowship and Residency Electronic Interactive Database. Fellowship-trained ophthalmologists had significantly higher research productivity, as measured using the h-index, than non-fellowship-trained ophthalmologists in this study (p < 0.0005). Academic ophthalmologists trained in vitreoretinal disease or ophthalmic pathology had the highest scholarly productivity compared with those in other ophthalmology subspecialties (p < 0.05). There was a significant increase in scholarly productivity with increasing academic rank from Assistant Professor to Professor (p < 0.05).

    To evaluate the research productivity of Canadian ophthalmology departments in terms of research volume, impact, funding, and cost-efficiency, and compare these measures with the top 6 U.S. departments. Systemic review. Using the Web of Science, we obtained the number of peer-reviewed research articles and citations in which an author listed an ophthalmology department (or affiliated university or hospital) from 2001 to 2010 in the top 10 ophthalmology and vision sciences journals, as well as the Canadian Journal of Ophthalmology. Federal research funding received from the Canadian Institutes of Health Research and National Institutes of Health was also obtained. The 3 universities that produced the highest number of articles were the University of Toronto (UofT), McGill University, and the University of British Columbia (UBC). UofT also produced the largest number of citations, followed by UBC and Dalhousie University. For the number of citations per article, the top 3 were the University of Ottawa, Dalhousie University, and the University of Calgary. McGill University, the University of Montreal, and UofT received the most federal funding. The 3 Canadian universities with the lowest funding (cost) per article were UofT, UBC, and McMaster University. The top contributors to the Canadian Journal of Ophthalmology from 2001 to 2010 were UofT, the University of Ottawa, and McGill University. Larger Canadian departments tended to generate higher research volume and obtained more federal funding, but smaller departments also contributed significantly, and sometimes surpassed larger departments, in terms of research impact and cost-efficiency. The top 6 U.S. departments generated higher research volume and received more federal research funding than their Canadian counterparts. However, when research impact and cost-efficiency were examined, Canadian departments performed similar to the top U.S. departments. Copyright © 2013 Canadian Ophthalmological Society. Published

Day-to-day clinical decisions rely heavily on the evidence base formed by the plethora of studies available to clinicians. Prospective, randomized controlled clinical trials are highly regarded as a robust study and are used to make important clinical decisions that directly affect patient care. The quality of study designs and statistical methods in major clinical journals is improving overtime,(1) and researchers and journals are being more attentive to statistical methodologies incorporated by studies. The results of well-designed ophthalmic studies with robust methodologies, therefore, have the ability to modify the ways in which diseases are managed.

    Atmospheric research in the Earth Sciences Division (610) consists of research and technology development programs dedicated to advancing knowledge and understanding of the atmosphere and its interaction with the climate of Earth. The Divisions goals are to improve understanding of the dynamics and physical properties of precipitation, clouds, and aerosols; atmospheric chemistry, including the role of natural and anthropogenic trace species on the ozone balance in the stratosphere and the troposphere; and radiative properties of Earth's atmosphere and the influence of solar variability on the Earth's climate. Major research activities are carried out in the Mesoscale Atmospheric Processes Laboratory, the Climate and Radiation Laboratory, the Atmospheric Chemistry and Dynamics Laboratory, and the Wallops Field Support Office. The overall scope of the research covers an end-to-end process, starting with the identification of scientific problems, leading to observation requirements for remote-sensing platforms, technology and retrieval algorithm development; followed by flight projects and satellite missions; and eventually, resulting in data processing, analyses of measurements, and dissemination from flight projects and missions. Instrument scientists conceive, design, develop, and implement ultraviolet, infrared, optical, radar, laser, and lidar technology to remotely sense the atmosphere. Members of the various laboratories conduct field measurements for satellite sensor calibration and data validation, and carry out numerous modeling activities. These modeling activities include climate model simulations, modeling the chemistry and transport of trace species on regional-to-global scales, cloud resolving models, and developing the next-generation Earth system models. Satellite missions, field campaigns, peer-reviewed publications, and successful proposals are essential at every stage of the research process to meeting our goals and maintaining leadership of the

    To assess the consistency of digitization of 35-mm slides as practiced in ophthalmologic research and estimate the impact of variation on semi-automated retinal vessel width measurements. A single retina slide was repeatedly digitized under various conditions on three scanner models. Average color levels were extracted from the resulting images, from which vessel widths were graded. The color channel level variations and possible correlation with width were analyzed. The Nikon 5000 scanner (Nikon Corp., Tokyo, Japan) had average coefficients of variation of 0.4, 2.3, and 0.5 for the red, green, and blue channel levels across all runs. The P values of the correlation between the red, green, and blue color channel levels and the width of the large retinal arteriole were .89, .27, and .58, respectively. The results suggest that the tested scanners digitize the 35-mm slides in a reliable manner without biasing the retinal vessel measurements. Copyright 2010, SLACK Incorporated.

    Recently the combination of adaptive optics and ophthalmology has made great progress and become highly effective. The retina disease is diagnosed by retina imaging technique based on scanning optical system, so the scanning of eye requires optical system characterized by great ability of anti-moving and optical aberration correction. The adaptive optics possesses high level of adaptability and is available for real time imaging, which meets the requirement of medical retina detection with accurate images. Now the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are widely used, which are the core techniques in the area of medical retina detection. Based on the above techniques, in China, a few adaptive optics systems used for eye medical scanning have been designed by some researchers from The Institute of Optics And Electronics of CAS(The Chinese Academy of Sciences); some foreign research institutions have adopted other methods to eliminate the interference of eye moving and optical aberration; there are many relevant patents at home and abroad. In this paper, the principles and relevant technique details of the Scanning Laser Ophthalmoscope and the Optical Coherence Tomography are described. And the recent development and progress of adaptive optics in the field of eye retina imaging are analyzed and summarized.

    Completion of a scientific manuscript for submission to a peer-reviewed journal is a daunting task for clinicians and scientists early in their careers. In an ongoing series, this third article is the first of 2 related articles that deal with the basics of producing a high-quality research manuscript. Although ophthalmology and vision science are the principal focus of this series, the general concepts essential to producing a quality manuscript are applicable to diverse fields of research. This article highlights the exponential growth in the scientific literature over the past 40 years, considers why it is important to publish completed research, and discusses the necessity of identifying the key messages of the research, and their context, in relation to the published literature. The ethics of publishing biomedical research and scientific misconduct, such as duplicate publication or plagiarism, are outlined. To avoid later conflict, there is a critical need for coworkers to carefully address authorship order and inclusion early in the manuscript process. Internationally agreed guidelines are identified to guide this process. The importance of choosing the correct journal for a specific article and the nature of basic citation indices are discussed. The article concludes by elaborating and contrasting different scientific writing styles and emphasizing the considerable importance of developing a representative title and applying clarity and appropriate structure to the abstract.

In parallel with the now-wider availability of low cost consumer-grade 3D printers (as evidenced by at least three brands of 3D printers for sale in a recent visit to an electronics store in Akihabara, Tokyo), commercial-grade 3D printers are ramping to higher and higher resolution with new capabilities, such as printing of multiple materials of different transparency, and with different mechanical and electrical properties. We highlight new work showing that 3D printing (stereolithography approaches in particular) has now risen as a viable technology to print whole microfluidic devices. Printing on 2D surfaces such as paper is an everyday experience, and has been used widely in analytical chemistry for printing conductive materials on paper strips for glucose and other electrochemical sensors. We highlight recent work using electrodes printed on paper for digital microfluidic droplet actuation. Finally, we highlight recent work in which printing of membrane-bound droplets that interconnect through bilayer membranes may open up an entirely new approach to microfluidic manufacturing of soft devices that mimic physiological systems.

    The ability to break up a volume of fluid into smaller pieces that are confined or separated to prevent molecular communication/transport is a key capability intrinsic to microfluidic systems. This capability has been used to develop or implement digital versions of traditional molecular analysis assays, including digital PCR and digital immunoassays/ELISA. In these digital versions, the concentration of the target analyte is in a range such that, when sampled into smaller fluid volumes, either a single molecule or no molecule may be present. Subsequent amplification is sensitive enough to obtain a digital readout of the presence of these target molecules. Advantages of such approaches that are claimed include quantification without calibration and robustness to variations in reaction conditions or times because the digital readout is less sensitive to absolute signal intensity levels. Weaknesses of digital approaches include a lower dynamic range of concentrations over which the assay is sensitive, which depends on the total volume that can be analyzed. We highlight recent efforts to expand the dynamic range of digital assays based on exploiting reaction/diffusion phenomena. A side-by-side study that evaluates the strengths of digital assays reveals that the majority of these claims are supported, with specific caveats. Finally, we highlight approaches to apply digital assays to analyze new types of reactions, including the active transport of protons across membranes by ATPases at the single protein level - perhaps opening up new biophysical understanding and screening opportunities, similar to widely deployed single-molecule ion channel analysis.

    Each year, millions of metric tons of the plastic produced for food packaging, personal care products, fishing gear, and other human activities end up in lakes, rivers, and the ocean. The breakdown of these primary plastics in the environment results in microplastics, small fragments of plastic typically less than 1-5 mm in size. These synthetic particles have been detected in all of the world's oceans and also in many freshwater systems, accumulating in sediment, on shorelines, suspended in surface waters, and being ingested by plankton, fish, birds, and marine mammals. While the occurrence of plastics in surface waters has been surveyed in a number of studies, the impacts of microplastics on marine organisms are still being elucidated. This highlight features three recent publications that explore the interactions of microplastics with planktonic organisms to clarify the effects of these pollutants on some of the ocean's smallest and most important inhabitants.

    In this issue we highlight a collection of recent work in which microfluidic parallelization and automation have been employed to address the increasing need for large amounts of quantitative data concerning cellular function--from correlating microRNA levels to protein expression, increasing the throughput and reducing the noise when studying protein dynamics in single-cells, and understanding how signal dynamics encodes information. The painstaking dissection of cellular pathways one protein at a time appears to be coming to an end, leading to more rapid discoveries which will inevitably translate to better cellular control--in producing useful gene products and treating disease at the individual cell level. From these studies it is also clear that development of large scale mutant or fusion libraries, automation of microscopy, image analysis, and data extraction will be key components as microfluidics contributes its strengths to aid systems biology moving forward.

    2005-10-01

    In an increasingly "publish or perish" clinical and academic environment, all clinicians and clinician-scientists involved in research must have a firm understanding of the measures commonly used to assess the quality of scientific journals and, by default, those extended to grade individual articles and authors. The publication of research is a vital part of clinical and experimental research, and citation analyses of research publications have increasingly been adopted as a means of assessing the apparent quality of journals and the research published therein. In the first of a series of articles for those embarking on ophthalmic and vision science research, this paper discusses the key features of citation analysis, concentrating on the 2004 Journal Citation Report figures for the field of ophthalmology that include 42 ophthalmology, vision science, physiological optics, and optometry journals. The Institute for Scientific Information (ISI) calculates a number of parameters including citation counts, Journal Impact Factor (JIF), Immediacy Index, and cited/citing half-life. This article discusses the methods of calculation and possible uses along with current controversies and potential abuses. The JIF and its relevance, potential bias, and limitations are discussed in depth as it has become the most widely used analysis of journal quality. The possible alternatives to ISI citation analysis are presented, and we conclude that citation analysis can be considered a reasonable measure of journal research quality only if used correctly.

  4. Perfluoroalkyl acids: recent research highlights | Science ...

    EPA Pesticide Factsheets

    Perfluorinated compounds are organic chemicals in which all hydrogen molecules of the carbon-chain are substituted by fluorine molecules. Generally, there are two types of perfluorinated compounds, the perfluoroalkanes that are primarily used clinically for oxygenation and respiratory ventilation, and the perfluoroalkyl acids (PFAAs). Environmentally relevant PFAAs are a family of about 30 chemicals that consist of a carbon backbone typically 4-14 molecules in length and a charged functional group composed of either sulfonates, carboxylates or phosphonates (and to a lesser extent, phosphinates). While many (>100) derivatives ofPFAAs (such as alcohols, amides, esters and acids) are used for industrial and consumer applications, they can be degraded or metabolized to PFAAs as end-stage products. Thus, PFAAs, rather than their intermediates or derivatives, have drawn the most public attention and research interest. The most widely known PFAAs are the eight-carbon (C8) sulfonate (perfluorooctane sulfonate, PFOS) and carboxylate (perfluorooctanoic acid, PFOA), although the C4 (perfluorobutane) and C6 (perfluorohexane) sulfonates, as well as the C4, C6 and C9 (perfluorononanoic) carboxylates have also been used in commerce. The perfluoroalkyl phosphonates (PFPAs) are fairly new entities for this class ofchemicals. They are typically used as leveling and wetting agents, and defoaming additives in the production of pesticides. They were considered biologically inert by

    Linear instability calculations at MSFC have suggested that the Geophysical Fluid Flow Cell (GFFC) should exhibit classic baroclinic instability at accessible parameter settings. Interest was in the mechanisms of transition to temporal chaos and the evolution of spatio-temporal chaos. In order to understand more about such transitions, high resolution numerical experiments for the physically simplest model of two layer baroclinic instability were conducted. This model has the advantage that the numerical code is exponentially convergent and can be efficiently run for very long times, enabling the study of chaotic attractors without the often devastating effects of low-order trunction found in many previous studies. Numerical algorithms for implementing an empirical orthogonal function (EOF) analysis of the high resolution numerical results were completed. Under conditions of rapid rotation and relatively low differential heating, convection in a spherical shell takes place as columnar banana cells wrapped around the annular gap, but with axes oriented along the axis of rotation; these were clearly evident in the GFFC experiments. The results of recent numerical simulations of columnar convection and future research plans are presented.

    In ophthalmology, various modalities and tests are utilized to obtain vital information on the eye's structure and function. For example, optical coherence tomography (OCT) is utilized to diagnose, screen, and aid treatment of eye diseases like macular degeneration or glaucoma. Such data are complemented by photographic retinal fundus images and functional tests on the visual field. DICOM isn't widely used yet, though, and frequently images are encoded in proprietary formats. The eXtensible Neuroimaging Archive Tool (XNAT) is an open-source NIH-funded framework for research PACS and is in use at the University of Iowa for neurological research applications. Its use for ophthalmology was hence desirable but posed new challenges due to data types thus far not considered and the lack of standardized formats. We developed custom tools for data types not natively recognized by XNAT itself using XNAT's low-level REST API. Vendor-provided tools can be included as necessary to convert proprietary data sets into valid DICOM. Clients can access the data in a standardized format while still retaining the original format if needed by specific analysis tools. With respective project-specific permissions, results like segmentations or quantitative evaluations can be stored as additional resources to previously uploaded datasets. Applications can use our abstract-level Python or C/C++ API to communicate with the XNAT instance. This paper describes concepts and details of the designed upload script templates, which can be customized to the needs of specific projects, and the novel client-side communication API which allows integration into new or existing research applications.

    Highlights of aeroacoustics research in the United States of America during 1998 are reported in a summary compiled from information provided by members of the Aeroacoustics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA) and other leading research groups in industry, national laboratories, and academia. The past few years have seen significant progress in aeroacoustics. Research has steadily progressed toward enhanced safety, noise benefits, and lower costs. Since industrial progress is generally not published in the archival literature, it is particularly important to highlight these accomplishments. This year we chose to report on five topics of great interest to the aerospace industry including a synopsis of fundamental research at universities and national laboratories. The topics chosen are: (1) Advanced Subsonic Technology (AST), (2) High Speed Research (HSR), (3) Rotorcraft, (4) Weapons bay aeroacoustics control and (5) Academic research including Computational AeroAcoustics (CAA). Although the information presented in this review is not all encompassing we hope that the topics covered will provide some insights into aeroacoustics activity in the U.S.

    2009-08-01

    To determine whether the concept of open access affects how articles are cited in the field of ophthalmology. Type of meta-analysis. Examination of 480 articles in ophthalmology in the experimental protocol and 415 articles in the control protocol. Four subject areas were chosen to search the ophthalmology literature in the PubMed database using the terms "cataract," "diabetic retinopathy," "glaucoma," and "refractive errors." Searching started in December of 2003 and worked back in time to the beginning of the year. The number of subsequent citations for equal numbers of both open access and closed access (by subscription) articles was quantified using the Scopus database and Google search engine. Number of authors, article type, country/region in which the article was published, language, and funding data were also collected for each article. A control protocol was also carried out to ascertain that the sampling method was not systematically biased by matching 6 ophthalmology journals (3 open access, 3 closed access) using their impact factors, and employing the same search methodology to sample open access and closed access articles. Number of citations. The total number of citations was significantly higher for open access articles compared to closed access articles for Scopus (mean 15.2 versus 11.5, P < .0005, Mann-Whitney U = 20029, and Google (mean 6.4 versus 4.0, P < .0005, Mann-Whitney U = 21281). However, univariate general linear model (GLM) analysis showed that access was not a significant factor that explained the citation data. Author number, country/region of publication, subject area, language, and funding were the variables that had the most effect and were statistically significant. Control protocol results showed no significant difference between open and closed access articles in regard to number of citations found by Scopus: open access: mean = 17.8; SD (standard deviation) = 23.70; closed access: mean = 19.1; SD = 20.31; Mann-Whitney test, P

    2014-08-01

    The benefits of ceramics in biomedical applications have been universally appreciated as they exhibit an extraordinarily broad set of physico-chemical, mechanical and biological properties which can be properly tailored by acting on their composition, porosity and surface texture to increase their versatility and suitability for targeted healthcare applications. Bioceramics have traditionally been used for the repair of hard tissues, such as bone and teeth, mainly due to their suitable strength for load-bearing applications, wear resistance (especially alumina, zirconia and composites thereof) and, in some cases, bone-bonding ability (calcium orthophosphates and bioactive glasses). Bioceramics have been also applied in other medical areas, like ophthalmic surgery; although their use in such a context has been scientifically documented since the late 1700s, the potential and importance of ceramic ocular implants still seem to be underestimated and an exhaustive, critical assessment is currently lacking in the relevant literature. The present review aims to fill this gap by giving a comprehensive picture of the ceramic-based materials and implants that are currently used in ophthalmology and pointing out the strengths and weaknesses of the existing devices. A prospect for future research is also provided, highlighting the potential of new, smart bioceramics able to carry specific added values which could have a significant impact on the treatment of ocular diseases.

    In the past decade, interest in boosting the collection of data on environmental pollutants while reducing costs has spurred intensive research into passive samplers, instruments that monitor the environment through the free flow of chemical species. These devices, although relatively inexpensive compared to active sampling technologies, are often tailored for collection of specific contaminants or monitoring of a single phase, typically water or air. Plants as versatile, natural passive samplers have gained increased attention in recent years due to their ability to absorb a diverse range of chemicals from the air, water, and soil. Trees, lichens, and other flora have evolved exquisite biological features to facilitate uptake of nutrients and water from the ground and conduct gas exchange on an extraordinary scale, making them excellent monitors of their surroundings. Sampling established plant specimens in a region also provides both historical and spatial data on environmental contaminants at relatively low cost in a non-invasive manner. This Highlight presents several recent publications that demonstrate how plant biomonitoring can be used to map the distribution of a variety of pollutants and identify their sources.

    The aim of this study was to update the practicing ophthalmologist on the English-language neuro-ophthalmology literature from the prior year. This study is a review of English-language literature from August 1, 2012, to August 1, 2013. The authors searched PubMed articles published from August 1, 2012, to August 1, 2013, limited to English-language publications including original articles, review articles, and case reports and excluding letters to the editor, unpublished work, and abstracts. We researched the following topics: pupillary abnormalities, eye movement dysfunction, neuromuscular diseases, optic neuropathies, optic neuritis and demyelinating disease including multiple sclerosis, lesions of the chiasm and posterior primary visual pathways, elevated intracranial pressure, tumors and aneurysms affecting the visual pathways, vascular diseases, higher visual functions, and neuroimaging advances. We intend to share clinically relevant literature of the past year with the practicing ophthalmologist. We aimed to highlight remarkable and interesting literature rather than exhaustively including all new neuro-ophthalmological publications of the year. We reviewed literature in the past year with a focus on relevance and novelty. This review updates the comprehensive ophthalmologist on neuro-ophthalmic topics.

    PubMed Central

    Greene, Deanna J.; Schlaggar, Bradley L.; Black, Kevin J.

    2015-01-01

    Tourette Syndrome (ts) is a developmental neuropsychiatric disorder of the central nervous system defined by the presence of chronic tics. While investigations of the underlying brain mechanisms have provided valuable information, a complete understanding of the pathophysiology of ts remains elusive. Neuroimaging methods provide remarkable tools for examining the human brain, and have been used to study brain structure and function in ts. In this article, we review ts neuroimaging studies published in 2014–2015. We highlight a number of noteworthy studies due to their innovative methods and interesting findings. Yet, we note that many of the recent studies share common concerns, specifically susceptibility to motion artifacts and modest sample sizes. Thus, we encourage future work to carefully address potential methodological confounds and to study larger samples to increase the potential for replicable results. PMID:26543796

  15. Research highlights: microfluidic-enabled single-cell epigenetics.

    2015-11-07

    Individual cells are the fundamental unit of life with diverse functions from metabolism to motility. In multicellular organisms, a single genome can give rise to tremendous variability across tissues at the single-cell level due to epigenetic differences in the genes that are expressed. Signals from the local environment or a history of signals can drive these variations, and tissues have many cell types that play separate roles. This epigenetic heterogeneity is of biological importance in normal functions such as tissue morphogenesis and can contribute to development or resistance of cancer, or other disease states. Therefore, an improved understanding of variations at the single cell level are fundamental to understanding biology and developing new approaches to combating disease. Traditional approaches to characterize epigenetic modifications of chromatin or the transcriptome of cells have often focused on blended responses of many cells in a tissue; however, such bulk measures lose spatial and temporal differences that occur from cell to cell, and cannot uncover novel or rare populations of cells. Here we highlight a flurry of recent activity to identify the mRNA profiles from thousands of single-cells as well as chromatin accessibility and histone marks on single to few hundreds of cells. Microfluidics and microfabrication have played a central role in the range of new techniques, and will likely continue to impact their further development towards routine single-cell epigenetic analysis.

    2014-04-07

    In this issue we highlight recent microtechnology-enabled approaches to control the physical and biomolecular environment around cells: (1) developing micropatterned surfaces to quantify cell affinity choices between two adhesive patterns, (2) controlling topographical cues to align cells and improve reprogramming to a pluripotent state, and (3) controlling gradients of biomolecules to maintain pluripotency in embryonic stem cells. Quantitative readouts of cell-surface affinity in environments with several cues should open up avenues in tissue engineering where self-assembly of complex multi-cellular structures is possible by precisely engineering relative adhesive cues in three dimensional constructs. Methods of simple and local epigenetic modification of chromatin structure with microtopography and biomolecular gradients should also be of use in regenerative medicine, as well as in high-throughput quantitative analysis of external signals that impact and can be used to control cells. Overall, approaches to engineer the cellular environment will continue to be an area of further growth in the microfluidic and lab on a chip community, as the scale of the technologies seamlessly matches that of biological systems. However, because of regulations and other complexities with tissue engineered therapies, these micro-engineering approaches will likely first impact organ-on-a-chip technologies that are poised to improve drug discovery pipelines.

    Jellinger, K A

    2006-11-01

    Alzheimer disease, a progressive neurodegenerative disorder of hitherto unknown etiology leading progressively to severe incapacity and death, has become the pandemic of the 21(st) century. On World Alzheimer Day, September 21, 2006, the 100(th) anniversary of the first description of the clinical and histological findings in this disorder by A. Alzheimer, was celebrated. This retrospective review of the most important events and advances in Alzheimer research presents its early history in which only clinical and histologic signs of this peculiar disease were described. Electron microscopy, quantitative morphology and modern biochemistry emerging in the second half of the 20(th) century opened a new era in dementia research with description of the ultrastructure and biochemistry of senile plaques and neurofibrillary tangles, the major disease markers of AD. Advances in the development of clinical, neuropathological, and neuroimaging criteria, modern instruments and algorithms in the diagnosis of the disorder followed, enabling long-term studies and more exact diagnosis of AD and related disorders. Landmark studies were the development of operational criteria for the post mortem diagnosis of AD based on semiquantitative assessment and developmental patterns of its major markers. Basic research gave insight into the molecular genetics and pathophysiology of AD, and, based on the biochemical findings, new pharmacological treatment options were opened. Recently, biological and other surrogate, in particular functional neuroimaging, markers allow an early detection of presymptomatic stages of AD, their risk factors and progression which, in the future, might be prevented or at least slowed by new therapeutic approaches. Since the etiology of AD is hitherto unknown, causative therapies are still not available. The paper discusses future research needs and challenges for developing new diagnostic strategies for early and accurate detection of neurodegenerative processes

    Chinese medicine syndrome (CMS, “ZHENG” in Chinese) is an understanding of the regularity of disease occurrence and development as well as a certain stage of a comprehensive response of patients with body condition. However, because of the complexity of CMS and the limitation of present investigation method, the research for deciphering the scientific basis and systematic features of CMS is difficult to go further. Metabolomics enables mapping of early biochemical changes in disease and hence provides an opportunity to develop predictive biomarkers. Moreover, its method and design resemble those of traditional Chinese medicine (TCM) which focuses on human disease via the integrity of close relationship between body and syndromes. In the systemic context, metabolomics has a convergence with TCM syndrome; therefore it could provide useful tools for exploring essence of CMS disease, facilitating personalized TCM, and will help to in-depth understand CMS. The integration of the metabolomics and CMS aspects will give promise to bridge the gap between Chinese and Western medicine and help catch the traditional features of CMS. In this paper, particular attention will be paid to the past successes in applications of robust metabolomic approaches to contribute to low-molecular-weight metabolites (biomarkers) discovery in CMS research and development.

    The Accelerator Test Facility (ATF) at Brookhaven National Laboratory has served as a user facility for accelerator science for over a quarter of a century. In fulfilling this mission, the ATF offers the unique combination of a high-brightness 80 MeV electron beam that is synchronized to a 1 TW picosecond CO2 laser. We unveil herein our plan to considerably expand the ATF's floor space with an upgrade of the electron beam's energy to 300 MeV and the CO2 laser's peak power to 100 TW. This upgrade will propel the ATF even further to the forefront of research on advanced accelerators and radiation sources, supporting the most innovative ideas in this field. We discuss emerging opportunities for scientific breakthroughs, including the following: plasma wakefield acceleration studies in research directions already active at the ATF; laser wakefield acceleration (LWFA), where the longer laser wavelengths are expected to engender a proportional increase in the beam's charge while our linac will assure, for the first time, the opportunity to undertake detailed studies of seeding and staging of the LWFA; proton acceleration to the 100-200 MeV level, which is essential for medical applications; and others.

    Summary The long and successful history of isotopic labeling experiments within natural products research has both changed and deepened our understanding of biosynthesis. As demonstrated in this article, the usage of isotopes is not at all old-fashioned, but continues to give important insights into biosynthetic pathways of secondary metabolites. This review with 85 cited references is structured by separate discussions of compounds from different classes including polyketides, non-ribosomal peptides, their hybrids, terpenoids, and aromatic compounds formed via the shikimate pathway. The text does not aim at a comprehensive overview, but instead a selection of recent important examples of isotope usage within biosynthetic studies is presented, with a special emphasis on mechanistic surprises.

  6. CERTS: Consortium for Electric Reliability Technology Solutions - Research Highlights

    SciTech Connect

    Eto, Joseph

    2003-07-30

    Historically, the U.S. electric power industry was vertically integrated, and utilities were responsible for system planning, operations, and reliability management. As the nation moves to a competitive market structure, these functions have been disaggregated, and no single entity is responsible for reliability management. As a result, new tools, technologies, systems, and management processes are needed to manage the reliability of the electricity grid. However, a number of simultaneous trends prevent electricity market participants from pursuing development of these reliability tools: utilities are preoccupied with restructuring their businesses, research funding has declined, and the formation of Independent System Operators (ISOs) and Regional Transmission Organizations (RTOs) to operate the grid means that control of transmission assets is separate from ownership of these assets; at the same time, business uncertainty, and changing regulatory policies have created a climate in which needed investment for transmission infrastructure and tools for reliability management has dried up. To address the resulting emerging gaps in reliability R&D, CERTS has undertaken much-needed public interest research on reliability technologies for the electricity grid. CERTS' vision is to: (1) Transform the electricity grid into an intelligent network that can sense and respond automatically to changing flows of power and emerging problems; (2) Enhance reliability management through market mechanisms, including transparency of real-time information on the status of the grid; (3) Empower customers to manage their energy use and reliability needs in response to real-time market price signals; and (4) Seamlessly integrate distributed technologies--including those for generation, storage, controls, and communications--to support the reliability needs of both the grid and individual customers.

    Emotion feeling is a phase of neurobiological activity, the key component of emotions and emotion-cognition interactions. Emotion schemas, the most frequently occurring emotion experiences, are dynamic emotion-cognition interactions that may consist of momentary/situational responding or enduring traits of personality that emerge over developmental time. Emotions play a critical role in the evolution of consciousness and the operations of all mental processes. Types of emotion relate differentially to types or levels of consciousness. Unbridled imagination and the ability for sympathetic regulation of empathy may represent both potential gains and losses from the evolution and ontogeny of emotion processes and consciousness. Unresolved issues include psychology's neglect of levels of consciousness that are distinct from access or reflective consciousness and use of the term "unconscious mind" as a dumpster for all mental processes that are considered unreportable. The relation of memes and the mirror neuron system to empathy, sympathy, and cultural influences on the development of socioemotional skills are unresolved issues destined to attract future research.

    Raw fossil material reserves are not inexhaustible and as prices continue to raise it is necessary to find new sources of alternative and renewable energy. Oils from oleaginous field crops (sunflower and rape) with properties close to those of fossil fuel could constitute an alternative source of energy for the production of raw materials. This is the context in which the 18th International Symposium on Plant lipids (ISPL) was held in Bordeaux from 20th to 25th July 2008 at "La Cité Mondiale". The 18th ISPL gathered 270 researchers from 33 countries. Sixty nine oral communications and 136 posters were presented during the 12 sessions of the Symposium. The sessions have covered all the different aspects of the Plant Lipid field including: Surface lipids: suberin, cutin and waxes, Fatty acids, Glycerolipids, Plant lipids as renewable sources of energy, Seed oils and bioengineering of metabolic pathways, Lipid catabolism, Models for lipid studies: lower plants, micro-organisms and others, Modifications of proteins by lipids, Sphingolipids, sterols and isoprenoids, Lipid signaling and plant stress responses, Lipid trafficking and membrane dynamics, New methods and technologies: functional lipidomics, fluxome, modelling.

    The National Spherical Torus Experiment (NSTX) is a collaborative mega-ampere-class spherical torus research facility with high power heating and current drive systems and the state-of-the-art comprehensive diagnostics. For the 2008 experimental campaign, the high harmonic fast wave (HHFW) heating efficiency in deuterium improved significantly with lithium evaporation and produced a record central Te of 5 keV. The HHFW heating of NBI-heated discharges was also demonstrated for the first time with lithium application. The EBW emission in H-mode was also improved dramatically with lithium which was shown to be attributable to reduced edge collisional absorption. Newly installed FIDA energetic particle diagnostic measured significant transport of energetic ions associated with TAE avalanche as well as n=1 kink activities. A full 75 channel poloidal CHERS system is now operational yielding tantalizing initial results. In the near term, major upgrade activities include a liquid-lithium divertor target to achieve lower collisionality regime, the HHFW antenna upgrades to double its power handling capability in H-mode, and a beam-emission spectroscopy diagnostic to extend the localized turbulence measurements toward the ion gyro-radius scale from the present concentration on the electron gyro-radius scale. For the longer term, a new center stack to significantly expand the plasma operating parameters is planned along with a second NBI system to double the NBI heating and CD power and provide current profile control. These upgrades will enable NSTX to explore fully non-inductive operations over a much expanded plasma parameter space in terms of higher plasma temperature and lower collisionality, thereby significantly reducing the physics parameter gap between the present NSTX and the projected next-step ST experiments.

    Neuro-ophthalmology is a medical subspecialty concerned on the nervous system diseases with ocular manifestations, this could be both sensory and motor, including ocular movements, papillary responses, and the structure changes of the brain and nervous system with ocular manifestations. Although neuro-ophthalmology in China has achieved some progress, certain problems still exist, such as the professional neuro-ophthalmology team and related academic organization are still absent in China; neuro-ophthalmology knowledge has not been popularized; the new technologies for diagnosis and treatment in neuro-ophthalmology have not been absorbed and applied; the coordination and cooperation with other related disciplines are not enough. We should actively promote the development of neuro-ophthalmology in China, including organization of a professional team of neuro-ophthalmology, popularization of neuro-ophthalmology knowledge to the ophthalmologists, development of research work in neuro-ophthalmology and the collaboration with international neuro-ophthalmologists.

    Many eye diseases have a genetic basis, and most can be caused by mutations in many different genes (extensive genetic heterogeneity). The retinal dystrophies are a good example: More than 200 genes have been identified for the isolated forms (Leber's congenital amaurosis, retinitis pigmentosa, cone-rod dystrophy, congenital stationary night blindness), and for syndromes that comprise additional dysfunctions or malformations of extraocular tissues and organs. Selecting genes for diagnostic testing has been difficult, and their analysis with the hitherto predominant DNA sequencing method (Sanger sequencing) has been extremely laborious: The phenotype rarely indicates the affected gene, and the contributions of the particular genes to the disease (e.g., to LCA) were largely unknown. Consequently, comprehensive genetic analyses were impossible in most cases. In the recent years, high-throughput sequencing technologies, summarized as next-generation sequencing (NGS), have revolutionized genetic research and, subsequently, genetic diagnostics. The latter has far-reaching implications for the individual management of patients with genetic eye diseases and their families.

    Mandić, Zdravko; Vatavuk, Zoran

    2004-06-01

    Like any other area of academic medicine in Croatia, academic ophthalmology has always been limited by or has depended on the factors outside the profession itself: during the communist regime, it was mostly political and ideological correctness of academic ophthalmologists, and today during the social and economic transition, it is the lack of finances, planning, and sophisticated technology. The four university eye clinics, which are the pillars of academic ophthalmology in Croatia, provide health care to most difficult cases, educate students, residents, and specialists, and do research. On the other hand, they lack equipment, room, and financial recognition. This ever growing imbalance between requirements imposed on academic ophthalmology today and its possibilities make it less and less attractive, especially in comparison with private practice. The possible solution lies in increasing the independence of ophthalmology from pharmaceutical industry and politics, especially in research and financial aspects.

    Simulation in medicine is an indispensable tool to improve doctors' responses to different situations, enhancing their performance. However, simulation in ophthalmology is a very recent trend, mainly because of the high complexity of developing newer teaching tools, with the need for highly realistic models, mostly in surgical ophthalmic simulation. The whole development of simulation in ophthalmology, from the very first attempts that used basic models, to the newer virtual reality models, allows for a comprehensive, faster, and more efficient development of skills necessary in basic and advance procedures in ophthalmology, creating a better learning environment, improving costs, and developing a very promising panorama, in which simulation can be incorporated in teaching programs all around the globe. Simulation in ophthalmology allows for better results in the formation of ophthalmologists, and it is becoming a new tool to achieve better results in medical and surgical procedures, thus improving outcomes and quality of care.

    Despite the fact that ophthalmology is one of the foremost branches of medicine, conceptualization of the structure and function of the eye barely advanced in ancient Western civilizations. At the early recovery of Persian civilization (9th century AD) after the extinction of the Sassanid Empire (7th century AD), translations of Greek medical textbooks played an important role in the development of medicine and the emergence of great Persian physicians such as Rhazes, Avicenna and others. Rhazes was a leading Persian physician whose medical teachings have as yet not been thoroughly explored. In addition to numerous books and articles in various fields, he authored a great medical Encyclopedia (al-Hawi al-Kabir) in 25 volumes. In this article, we are going to compare Rhazes’ particular viewpoints about ophthalmology with those of other famous Persian physicians and some recent essays and textbooks. For this purpose we reviewed Rhazes’ second volume of al-Hawi that is dedicated exclusively to ophthalmology and contains some major topics of ophthalmology including anatomy, physiology, pathology, diseases, disorders and treatments. Important themes were carefully extracted and compared with the tenets of modern ophthalmology. After collating Rhazes’ viewpoints with the latest findings in this field, it was concluded that he had brilliantly written about the signs and symptoms, etiology and treatment of many eye disorders more than a thousand years ago. The amazing point is that there was no accurate equipment at the time to help him in his investigations. This study proved that Rhazes’ theories conform to recent knowledge about ophthalmology in many aspects, and could therefore be the subject of further investigations. PMID:26587199

    Mavroforou, Anna; Michalodimitrakis, Emmanuel

    2003-08-01

    The aims of this paper are to point out the importance of coherence in established guidelines in daily practice, highlight the value of signed patient informed consent forms and stress the value of a good understanding of the law, while focusing on issues related to malpractice in ophthalmology. Search of the current relevant literature. The most common causes of medical litigation in ophthalmology are related to LASIK surgery, cataract surgery, glaucoma care, radial keratotomy for myopia reduction and failure to diagnose binocular vision anomalies in children and adults in a timely fashion. The litigation raised in most cases is driven by unfavourable outcomes and not by malpractice. Maintenance of high standards in daily practice, with continuous training and clear communication along with the appropriate documentation of any procedure carried out, may improve the professional safety of practising eye specialists in the event of medical litigation. Although the use of patient informed consent varies substantially among European countries, it may serve as useful evidence in the physician's defence.

    Due to their complexity and wide-ranging utility, biomacromolecular research is an especially interdisciplinary branch of chemistry. It is my goal that the Biomacromolecules subject area of Chemistry Central Journal will parallel this richness and diversity. In this inaugural commentary, I attempt to set the stage for achieving this by highlighting several areas where biomacromolecular research overlaps more traditional chemistry sub-disciplines. Specifically, it is discussed how Materials Science and Biotechnology, Analytical Chemistry, Cell Biology and Chemical Theory are each integral to modern biomacromolecular research. Investigators with reports in any of these areas, or any other dealing with biomacromolecules, are encouraged to submit their research papers to Chemistry Central Journal. PMID:17939851

  2. Fee splitting in ophthalmology.

    PubMed

    Levin, Alex V; Ganesh, Anuradha; Al-Busaidi, Ahmed

    2011-02-01

    Fee splitting and co-management are common practices in ophthalmology. These arrangements may conflict with the ethical principles governing the doctor-patient relationship, may constitute professional misconduct, and at times, may be illegal. Implications and perceptions of these practices may vary between different cultures. Full disclosure to the patient may minimize the adverse effects of conflicts of interest that arise from these practices, and may thereby allow these practices to be deemed acceptable by some cultural morays, professional guidelines, or by law. Disclosure does not necessarily relieve the physician from a potential ethical compromise. This review examines the practice of fee splitting in ophthalmology, its legal implications, the policies or guidelines governing such arrangements, and the possible ethical ramifications. A comparative view between 3 countries, Canada, the United States, and Oman, was conducted; illustrating that even in disparate cultures, there may be some universality to the application of ethical principles.

    General anesthesia is less utilized in ophthalmology. There are some criteria that lead to general anesthesia: patients with auditive debility, aged and senile patients, allergic patients, children and young patients, and subjects who totally refuse loco-regional procedures. General anesthesia utilizes as basic products: narcotic substances, analgesic substances, or neuroleptic substances utilized separately or associated, with posology adaptated to several factors: patients' pulse, physical statement, age, duration. The type of anesthetic substance depends also of specialist anesthetist experience.

    The American Society for Parenteral and Enteral Nutrition (A.S.P.E.N.) Research Workshop, "Using Nutrigenomics and Metabolomics in Clinical Nutrition Research," was held on January 21, 2012, in Orlando, Florida. The conference brought together experts in human nutrition who use nutrigenomic and metabolomic methods to better understand metabolic individuality and nutrition effects on health. We are beginning to understand how genetic variation and epigenetic events alter requirements for and responses to foods in our diet (the field of nutrigenetics/nutrigenomics and epigenetics). At the same time, methods for profiling almost all of the products of metabolism in plasma, urine, and tissues (metabolomics) are being refined. The relationships between diet and nutrigenomic-metabolomic profiles, as well as between these profiles and health, are being elucidated, and this will dramatically alter clinical practice in nutrition.

  7. Understanding Energy Impacts of Oversized Air Conditioners; NREL Highlights, Research & Development, NREL (National Renewable Energy Laboratory)

    SciTech Connect

    2015-06-01

    This NREL highlight describes a simulation-based study that analyzes the energy impacts of oversized residential air conditioners. Researchers found that, if parasitic power losses are minimal, there is very little increase in energy use for oversizing an air conditioner. The research demonstrates that new residential air conditioners can be sized primarily based on comfort considerations, because capacity typically has minimal impact on energy efficiency. The results of this research can be useful for contractors and homeowners when choosing a new air conditioner or heat pump during retrofits of existing homes. If the selected unit has a crankcase heater, performing proper load calculations to be sure the new unit is not oversized will help avoid excessive energy use.

    Highlights of aeroacoustics research in the United States of America during 1998 are reported in a summary compiled from information provided by members of the Aeroacoustics Technical Committee of the American Institute of Aeronautics and Astronautics (AIAA) and other leading research groups in industry, national laboratories, and academia. The past few years have seen significant progress in aeroacoustics. Research has steadily progressed toward enhanced safety, noise benefits, and lower costs. Since industrial progress is generally not published in the archival literature, it is particularly important to highlight these accomplishments. This year we chose to report on five topics of great interest to the aerospace industry including a synopsis of fundamental research at universities and national laboratories. The topics chosen are: (1) advanced subsonic technology (AST), (2) high-speed research (HSR), (3) rotorcraft, (4) weapons bay aeroacoustics control and (5) academic research including computational aeroacoustics (CAA). Although the information presented in this review is not all encompassing, we hope that the topics covered will provide some insights into aeroacoustics activity in the U.S. With contributions from members of the AIAA Aeroacoustics Technical Committee and others including D. Huff, E. Envia, C. Hughes, J. Bridges, and N. Saiyed (NASA Glenn), R. Hixon (ICOMP), R. M. Nallasamy (Dynacs, Inc.), M. Ponton, J. Posey (NASA Langley), C. Horne and P. Soderman (NASA Ames), D.

  9. Air Force Research Laboratory (AFRL) research highlights, September--October 1998

    SciTech Connect

    1998-10-01

    New AFOSR-sponsored research shows that exhausts from solid-fueled rocket motors have very limited impact on stratospheric ozone. The research provides the Air Force with hard data to support continued access to space using the existing fleet of rockets and rocket technology. This basic research data allows the Air Force to maintain a strongly proactive environmental stance, and to meet federal guidelines regarding environmental impacts. Long-standing conjecture within the international rocket community suggests that chlorine compounds and alumina particulates produced in solid rocket motor (SRM) exhausts could create localized, temporary ozone toss in rocket plumes following launches. The extent of a local depletion of ozone and its environmental impact depends on details of the composition and chemistry in these plumes. Yet direct measurements of plume composition and plume chemistry in the stratosphere had never been made. Uncertainty about these details left the Air Force and commercial space launch capability potentially vulnerable to questions about the environmental impact of rocket launches. In 1995, APOSR and the Space and Missiles Systems Center Launch Programs Office (SMC/CL) jointly began the Rocket Impacts on Stratospheric Ozone (RISO) program to make the first-ever detailed measurements of rocket exhaust plumes. These measurements were aimed at understanding how the exhaust from large rocket motors effect the Earth`s stratospheric ozone layer. The studies determined: the size distribution of alumina particles in these exhausts, the amount of reactive chlorine in SRM exhaust, and the size and duration of localized ozone toss in the rocket plumes.

    The 2009 SEG Summer Research Workshop on CO2 Sequestration Geophysics was held August 23-27, 2009 in Banff, Canada. The event was attended by over 100 scientists from around the world, which proved to be a remarkably successful turnout in the midst of the current global financial crisis and severe corporate travel restrictions. Attendees included SEG President Larry Lines (U. Calgary), and CSEG President John Downton (CGG Veritas), who joined SRW Chairman David Lumley (UWA) in giving the opening welcome remarks at the Sunday Icebreaker. The workshop was organized by an expert technical committee (see side bar) representing a good mix of industry, academic, and government research organizations. The format consisted of four days of technical sessions with over 60 talks and posters, plus an optional pre-workshop field trip to the Columbia Ice Fields to view firsthand the effects of global warming on the Athabasca glacier (Figures 1-2). Group technical discussion was encouraged by requiring each presenter to limit themselves to 15 minutes of presentation followed by a 15 minute open discussion period. Technical contributions focused on the current and future role of geophysics in CO2 sequestration, highlighting new research and field-test results with regard to site selection and characterization, monitoring and surveillance, using a wide array of geophysical techniques. While there are too many excellent contributions to mention all individually here, in this paper we summarize some of the key workshop highlights in order to propagate new developments to the SEG community at large.

    The article highlights the career of Professor Mansour Ali Haseeb (1910 - 1973; DKSM, Dip Bact, FRCPath, FRCP [Lond]), a pioneer worker in health, medical services, biomedical research and medical education in the Sudan. After his graduation from the Kitchener School of Medicine (renamed, Faculty of Medicine, University of Khartoum [U of K]) in 1934, he devoted his life for the development of laboratory medicine. He became the first Sudanese Director of Stack Medical Research Laboratories (1952 - 1962). He made valuable contributions by his services in the vaccine production and implementation programs, most notably in combating small pox, rabies and epidemic meningitis. In 1963 he became the first Sudanese Professor of Microbiology and Parasitology and served as the first Sudanese Dean of the Faculty of Medicine, U of K (1963-1969). He was an active loyal citizen in public life and served in various fields outside the medical profession. As Mayor of Omdurman, he was invited to visit Berlin in 1963 by Willy Brandt, Mayor of West Berlin (1957-1966) and Chancellor of the Federal Republic of Germany (1969 to 1974). Also as Mayor of Omdurman, he represented the City in welcoming Queen Elizabeth II during her visit to Sudan in February 1965. He also received State Medals from Egypt and Ethiopia. In 1973 he was appointed Chairman of the Sudan Medical Research Council, and was awarded the international Dr. Shousha Foundation Prize and Medal by the WHO for his contribution in the advancement of health, research and medical services.

  19. Research highlights: laboratory studies of the formation and transformation of atmospheric organic aerosols.

    PubMed

    Borduas, Nadine; Lin, Vivian S

    2016-04-01

    Atmospheric particles are emitted from a variety of anthropogenic and natural precursors and have direct impacts on climate, by scattering solar irradiation and nucleating clouds, and on health, by causing oxidative stress in the lungs when inhaled. They may also form from gaseous precursors, creating complex mixtures of organic and inorganic material. The chemical composition and the physical properties of aerosols will evolve during their one-week lifetime which will consequently change their impact on climate and health. The heterogeneity of aerosols is difficult to model and thus atmospheric aerosol research strives to characterize the mechanisms involved in nucleating and transforming particles in the atmosphere. Recent advances in four laboratory studies of aerosol formation and aging are highlighted here.

    The advent of nanotechnology promises to drastically accelerate progress toward nanomedicine. Nanoscale particles in the size range of cellular and molecular structures, which are usually referred to as nanoparticles (NPs), can be designed to improve penetration, sustained delivery, and controlled release of different drugs for ophthalmic therapeutic applications. After explaining different forms of routinely-used NPs such as nanomicelles, nanosuspensions, liposomes, and dendrimers, potential applications of NPs for the treatment of anterior and posterior eye diseases will be discussed by highlighting their ubiquitous properties. Furthermore, genotoxicity, cytotoxicity, and neuronal toxicity, as the major limiting factors in the wider application of NPs in medical sciences have been discussed, and novel diagnostic techniques and nanomedical tools being utilized in ophthalmology have been introduced. The development of an effective, nontoxic nanoscale biomaterials, in combination with identifying the best delivery systems, will shed more light on the future applications of nanotechnology in ophthalmology.

    Information systems managing image-based data for telemedicine or clinical research applications require a reference standard representing the correct diagnosis. Accurate reference standards are difficult to establish because of imperfect agreement among physicians, and discrepancies between clinical vs. image-based diagnosis. This study is designed to describe the development and evaluation of reference standards for image-based diagnosis, which combine diagnostic impressions of multiple image readers with the actual clinical diagnoses. We show that agreement between image reading and clinical examinations was imperfect (689 [32%] discrepancies in 2148 image readings), as was inter-reader agreement (kappa 0.490-0.652). This was improved by establishing an image-based reference standard defined as the majority diagnosis given by three readers (13% discrepancies with image readers). It was further improved by establishing an overall reference standard that incorporated the clinical diagnosis (10% discrepancies with image readers). These principles of establishing reference standards may be applied to improve robustness of real-world systems supporting image-based diagnosis. PMID:25954463

    This review summarizes the most relevant articles from the field of neuro-ophthalmology published in the Journal of Neurology from January 2012 to July 2013. With the advent of video-oculography, several articles describe new applications for eye movement recordings as a diagnostic tool for a wide range of disorders. In myasthenia gravis, anti-Kv1.4 and anti-Lrp4 have been characterized as promising novel autoantibodies for the diagnosis of hitherto 'seronegative' myasthenia gravis. Several articles address new diagnostic and therapeutic approaches to neuromyelitis optica, which further sharpen its profile as a distinct entity. Additionally, 4-aminopyridine has become a standard therapeutic for patients with cerebellar downbeat nystagmus. Finally, revised diagnostic criteria have been proposed for chronic relapsing inflammatory optic neuropathy based on a careful literature review over the last decade.

    Messmer, E M

    2012-11-01

    Preservatives are a legal requirement for eye drops in multidose containers. Moreover, they are necessary for stabilization and intraocular penetration for a number of ophthalmic preparations. Most preservatives act in a relatively unspecific manner as detergents or by oxidative mechanisms and thereby cause side effects at the ocular surface. They may also affect the lens, trabecular meshwork and the retina. Benzalkonium chloride is the most commonly used preservative in ophthalmology and is more toxic than other or newer preservatives, such as polyquaternium-1 (Polyquad), sodium perborate, oxychloro-complex (Purite®) and SofZia. Preservative-free topical medication is highly recommended for patients with ocular surface disease, frequent eye drop administration, proven allergy to preservatives and contact lens wear.

  7. Helminth parasites in pigs: new challenges in pig production and current research highlights.

    PubMed

    Roepstorff, A; Mejer, H; Nejsum, P; Thamsborg, S M

    2011-08-04

    Helminths in pigs have generally received little attention from veterinary parasitologists, despite Ascaris suum, Trichuris suis, and Oesophagostomum sp. being common worldwide. The present paper presents challenges and current research highlights connected with these parasites. In Danish swine herds, new indoor production systems may favour helminth transmission and growing knowledge on pasture survival and infectivity of A. suum and T. suis eggs indicates that they may constitute a serious threat to outdoor pig production. Furthermore, it is now evident that A. suum is zoonotic and the same may be true for T. suis. With these 'new' challenges and the economic impact of the infections, further research is warranted. Better understanding of host-parasite relationships and A. suum and T. suis egg ecology may also improve the understanding and control of human A. lumbricoides and T. trichiura infections. The population dynamics of the three parasites are well documented and may be used to study phenomena, such as predisposition and worm aggregation. Furthermore, better methods to recover larvae have provided tools for quantifying parasite transmission. Thus, an on-going study using helminth naïve tracer pigs has surprisingly demonstrated that soil infectivity with A. suum and T. suis increases during the first 2-3 years after pasture contamination. Though all three helminth species stimulate the Th2 arm of the immune system, Oesophagostomum seems weakly immunogenic, perhaps via specific modulation of the host immune system. A. suum and T. suis potently modulate the host immune response, up-regulating Th2 and down-regulating Th1. As a consequence, A. suum may compromise the efficacy of certain bacterial vaccines, whereas T. suis, which establish only short-term in humans, is a favourite candidate for down-regulating autoimmune Th1-related diseases in man. Some basic research findings have offered new possibilities for future sustainable control measures. For example

    Accompany with dramatically growth of large-scale biological databases (such as human genome sequence), improvement of life science and development of international clinical trials, science offers great potential for improving health care through precision medicine. As a hot topic recently, precision medicine might launch a revolution of the methodology in medical research. How to achieve precision medicine in clinical ophthalmology by means of biological data mining is a challenge for ophthalmologist-scientists. The best approach for advanced individual medicine is to buildup the digital ophthalmology, which includes human eye biobank, national biological databases network, clinical department, basic research lab, and international clinical trial center. The system of digital ophthalmology could explore the methods for ophthalmology research, integrate the source of eye biologic databases, promote international cooperation, and thus eventually supply the opportunity for translational medicine.

  9. Contributions of liquid chromatography-mass spectrometry to "highlights" of biomedical research.

    2003-06-06

    Combined chromatographic and mass spectrometric techniques and in particular liquid chromatography-mass spectrometry (LC-MS) have been contributing in a decisive way to the progress of life sciences in general. Thus, the number of document entries in the US National Library of Medicine (MEDLINE) for articles dealing with LC-MS was 738 in 1991 and 2285 in 2001, with a total of 13 147 for the whole 10-year period, an increase of 310%. From these figures, we can ascertain that the total usage of combined LC-MS techniques is of the order of 40% relative to all of the MS publications collected in MEDLINE for the same period. However, from the perspective of real advances in medicine, it becomes difficult to identify what is outstanding in this field. The aim of this review was not to provide another LC-MS review, but an overview of the current status of the presence, visibility and impact of combined LC-MS techniques in biomedical research. The idea being to spot "highlight" literature contributions with the potential to become in the short or medium term real assets in a doctor's daily medical practice. In other words, after several truly remarkable technical achievements reported within the past decade, are we any closer to making LC-MS a useful and practical diagnostic tool for molecular diagnostics and personalized medicine? To approach this question, a literature survey was carried out to define: (i) the presence of LC-MS in the biomedical literature (MEDLINE) and its weight relative to the whole field of biological and biomedical mass spectrometry; (ii) the role of LC-MS in recent milestone biomedical contributions; and (iii) the present and future role of new LC-MS technology in medical diagnosis.

    Silverman, Ronald H

    2016-01-01

    The use of focused ultrasound to obtain diagnostically significant information about the eye goes back to the 1950s. This review describes the historical and technological development of ophthalmic ultrasound and its clinical application and impact. Ultrasound, like light, can be focused, which is crucial for formation of high-resolution, diagnostically useful images. Focused, single-element, mechanically scanned transducers are most common in ophthalmology. Specially designed transducers have been used to generate focused, high-intensity ultrasound that through thermal effects has been used to treat glaucoma (via ciliodestruction), tumors, and other pathologies. Linear and annular transducer arrays offer synthetic focusing in which precise timing of the excitation of independently addressable array elements allows formation of a converging wavefront to create a focus at one or more programmable depths. Most recently, linear array-based plane-wave ultrasound, in which the array emits an unfocused wavefront and focusing is performed solely on received data, has been demonstrated for imaging ocular anatomy and blood flow. While the history of ophthalmic ultrasound extends back over half-a-century, new and powerful technologic advances continue to be made, offering the prospect of novel diagnostic capabilities.

    Nanotechnology involves the creation and use of materials and devices at the size scale of intracellular structures and molecules, and involves systems and constructs in the order of <100 nm. The aim of nanomedicine is the comprehensive monitoring, control, construction, repair, defence, and improvement of human biological systems at the molecular level, using engineered nanodevices and nanostructures that operate massively in parallel at the single-cell level, ultimately to achieve medical benefit. In this review we consider general principles of nanotechnology as applied to nanomedicine (e.g., biomimicry and pseudointelligence). Some applications of nanotechnology to ophthalmology are described (including treatment of oxidative stress; measurement of intraocular pressure; theragnostics; use of nanoparticles to treat choroidal new vessels, prevent scarring after glaucoma surgery, and treat retinal degenerative disease with gene therapy; prosthetics; and regenerative nanomedicine). Nanotechnology will revolutionize our approach to current therapeutic challenges (e.g., drug delivery, postoperative scarring) and will enable us to address currently unsolvable problems (e.g., sight-restoring therapy for patients with retinal degenerative disease). Obstacles to the incorporation of nanotechnology remain, such as safe manufacturing techniques and unintended biological consequences of nanomaterial use. These obstacles are not insurmountable, and revolutionary treatments for ophthalmic diseases are expected to result from this burgeoning field.

    1992-03-01

    The clinical application of lasers in ophthalmology is schematized, showing for each anatomic eye structure, pathologies that may be treated through this procedure. In the cornea, the unusual laser practice for suture removals and the promising possibility of the excimer laser in refractive surgery are discussed. In the iris, the camerular angle, and the ciliary body, the laser application is essentially used to treat the glaucoma and other situations that are not so frequent. The capsulotomy with YAG LASER is used in the treatment of structures related with crystalline and, at least, the treatment of the retina and choroid pathology is expanded. A. A. explained the primordial interest and important of laser in the diabetic retinopathy treatment and some results in patients with more than 5 years of evolution are: 55 of the patients with proliferative diabetic retinopathy (RDP) treated for more than 5 years noticed their vision improved or stabilized; 5 years after treating patients with PDR, 49.3 had their vision stabilized or even improved, provided the diabetics had declared itself more than 20 years ago, versus 61.7 provided the diabetics had declared itself less than 20 years before; finally, 53.8 of the patients under 40-years-old when the diabetics was diagnosed, had their vision improved or at least stabilized 5 years after the beginning of the treatment. On the other side, when patients were over 40 years old when the diabetics was diagnosed percentage increased to 55.9. This study was established in the follow-up of 149 cases over 10 years.

    2016-01-01

    Purpose of review Crowdsourcing involves the use of the collective intelligence of online communities to produce solutions and outcomes for defined objectives. The use of crowdsourcing is growing in many scientific areas. Crowdsourcing in ophthalmology has been used in basic science and clinical research, however it also shows promise as a method with wide-ranging applications. This review presents current findings on the use of crowdsourcing in ophthalmology and potential applications in the future. Recent findings Crowdsourcing has been used to distinguish normal retinal images from images with diabetic retinopathy; the collective intelligence of the crowd was able to correctly classify 81% of 230 images (19 unique) for USD$1.10 per eye in 20 minutes. Crowdsourcing has also been used to distinguish normal optic discs from abnormal ones with reasonable sensitivity (83–88%), but low specificity (35–43%). Another study used crowdsourcing for quick and reliable manual segmentation of OCT images. Outside of ophthalmology, crowdsourcing has been used for text and image interpretation, language translation, and data analysis. Summary Crowdsourcing has the potential for rapid and economical data processing. Among other applications, it could be used in research settings to provide the “ground-truth” data, and in the clinical settings to relieve the burden of image processing on experts. PMID:26761188

    Sanches, Maria Aparecida; Scarpi, Marinho Jorge

    2005-01-01

    Research on the field of organizational ethics to investigate to which extent ophthalmologic clinics, inserted in the competitive atmosphere, in the condition of organizations in search of survival, subordinate ethics to competitiveness in the managerial praxis, that is, in the administrative sphere. Kohlberg is taken as theoretical reference, approaching the theme of ethical subordination to competitiveness. The instrument to evaluate moral behaviors of organizations, elaborated by Licht, is applied. The quantitative method is used, adopting analytic instruments, such as Q of Yule and non parametric tests, when dealing with the data of 41 ophthalmologic clinics. The results of the research seem to indicate that administrators of ophthalmologic clinics of greater performance subordinate ethical principles to competitiveness, seeking to assure the survival of the company and, when confronted with the instrument to evaluate their moral behavior, proposed by Kohlberg, have a significantly smaller presence in the postconventional stage than administrators of ophthalmologic clinics with a smaller performance. One may affirm, according to non parametric tests, at the level of significance of 0.05, that the levels of moral development of the two groups differ significantly. The obtained results are according to the literature, especially concerning the "paradox of the ethical subordination and competitiveness". They also suggest that the warrant of the survival of the company tends to reduce the perception of the groups in power regarding the problems that happen in the community, and that a reduction of the ethical values subordinated to competition occurs, and such reduction provokes growing feelings of economical disputes in the social sphere.

    In ophthalmology, ultrasound is applied in diagnostics as well as in surgery and therapy. This paper gives a short survey on both applications. Ultrasonic phacoemulsification is of considerable practical importance for modern cataract micro-surgery with intraocular lens implantation. Applications of that kind require consideration of ultrasonic bioeffects and equipment safety. Diagnostic use of ultrasound includes biometry (echometry), tissue examination and characterization, and vascular investigations in eye and orbit. The application of diagnostic ultrasound on in-patients, its individual indications, and the appropriate methods (A, B, automatic biometric devices for axial length measuring, M, Doppler) are described. Examples of commercially available instruments for the different applications are given. In comparison with other disciplines ophthalmic A-mode and B-mode echography is characterized by: refined depth resolution and lateral resolution; the important part of quantitative methods for clinical evaluation of echograms; and the advanced level of quality assurance for equipment performance. Refined tissue evaluation requires optimized and reproducible equipment parameters. To ensure these conditions the clinical echographer must be educated and willing to test performance and quality of his equipment. Finally, a perspective of actual research in diagnostic ultrasound of the eye is given.

    To determine the factors most important to applicants when selecting an ophthalmology residency program. Cross-sectional survey. All 595 applicants who submitted a rank list to the Ophthalmology Residency Matching Program for the 2012 match. Participants anonymously completed a 25-item questionnaire after the submission of their rank lists. A multiple-choice format and ordinal scale were used to query applicants on demographics, career plans, and the importance of factors related to program characteristics. One question allowed a free text response to identify factors that caused the applicant to rank a program lower than other programs or not at all (i.e., "red flag"). Factors important to applicants when creating their rank lists. The response rate was 37% (218/595). The 3 most important factors affecting rank lists were resident-faculty relationships, clinical and surgical volume, and diversity of training. The fourth most important was the interview experience with faculty; poor interview experience was the most frequently cited "red flag." Age, gender, and marital status did not affect how applicants rated factors. Applicants planning a post-residency fellowship or an academic career placed greater importance on opportunities for resident research and a program's prestige (P<0.0001). Female and ethnic minority applicants placed greater importance on the diversity of faculty and residents by gender or ethnicity (P<0.0001). Applicants rated educational and interpersonal factors as more important than geographic factors when selecting an ophthalmology residency program. Future career plans and demographic factors influenced the rating of specific factors. The results of this study provide a useful resource to programs preparing for the match.

    Regenerative medicine is an emerging area that will influence the treatment of joint diseases in the future. It involves the use of biomaterials, cell therapy, and bioactive factors such as growth factors, drugs and small molecules, to regenerate damaged tissues. This "year in review" highlights a personal selection of promising studies published between March 2013 and March 2014 that inform on the direction in which this field is moving. This multidisciplinary field has been very active, with rapid development of new technologies that emerge from basic sciences such as the possibility to generate pluripotent stem cells without genetic modification and genetic engineering of growth factors to enhance their capacity to induce tissue repair. The increasing knowledge of the interaction between all tissues in the joint, such as the effect of bone remodeling and synovial inflammation on cartilage repair, will eventually make tissue regeneration in a compromised joint environment possible.

    Recognized for conducting cutting-edge science in the field of radiation health effects research, the Department of Energy's (DOE) Russian Health Studies Program has continued to generate excitement and enthusiasm throughout its 23-year mission to assess worker and public health risks from radiation exposure resulting from nuclear weapons production activities in the former Soviet Union. The three goals of the Program are to: (1) clarify the relationship between health effects and chronic, low-to-medium dose radiation exposure; (2) estimate the cancer risks from exposure to gamma, neutron, and alpha radiation; and (3) provide information to the national and international organizations that determine radiation protection standards and practices. Research sponsored by DOE's Russian Health Studies Program is conducted under the authority of the Joint Coordinating Committee for Radiation Effects Research (JCCRER), a bi-national committee representing Federal agencies in the United States and the Russian Federation. Signed in 1994, the JCCRER Agreement established the legal basis for the collaborative research between USA and Russian scientists to determine the risks associated with working at or living near Russian former nuclear weapons production sites. The products of the Program are peer-reviewed publications on cancer risk estimates from worker and community exposure to ionizing radiation following the production of nuclear weapons in Russia. The scientific return on investment has been substantial. Through 31 December 2015, JCCRER researchers have published 299 peer-reviewed publications. To date, the research has focused on the Mayak Production Association (Mayak) in Ozersk, Russia, which is the site of the first Soviet nuclear weapons production facility, and people in surrounding communities along the Techa River. There are five current projects in the Russian Health Studies Program: two radiation epidemiology studies; two historical dose reconstruction

    The fifth biennial Berry Health Benefits Symposium showcased recent research supporting the positive effects of berry consumption on human health and disease. Remarkably, the vast majority of oral papers covered data accumulated from in vivo studies, which underscores how berry health research has advanced since the inception of this symposium in 2005. Similar to the past, research presented at this meeting was primarily focused on the major commercially cultivated berries in North America, namely, blackberry, blueberry, black raspberry, cranberry, red raspberry, and strawberry. Despite this, on the basis of similar compositional chemistry, it is possible that similar biological effects may also be extended to other small soft-fleshed "berry-type" fruits popular in other parts of the world including Europe, Asia, and South America. Overall, this symposium continues to add to the growing body of data supporting the positive impact of berry fruit consumption on human health promotion and disease risk reduction.

  19. Plasmid rolling-circle replication: highlights of two decades of research.

    PubMed

    Khan, Saleem A

    2005-03-01

    This review provides a historical perspective of the major findings that contributed to our current understanding of plasmid rolling-circle (RC) replication. Rolling-circle-replicating (RCR) plasmids were discovered approximately 20 years ago. The first of the RCR plasmids to be identified were native to Gram-positive bacteria, but later such plasmids were also identified in Gram-negative bacteria and in archaea. Further studies revealed mechanistic similarities in the replication of RCR plasmids and the single-stranded DNA bacteriophages of Escherichia coli, although there were important differences as well. Three important elements, a gene encoding the initiator protein, the double strand origin, and the single strand origin, are contained in all RCR plasmids. The initiator proteins typically contain a domain involved in their sequence-specific binding to the double strand origin and a domain that nicks within the double strand origin and generates the primer for DNA replication. The double strand origins include the start-site of leading strand synthesis and contain sequences that are bound and nicked by the initiator proteins. The single strand origins are required for synthesis of the lagging strand of RCR plasmids. The single strand origins are non-coding regions that are strand-specific, and contain extensive secondary structures. This minireview will highlight the major findings in the study of plasmid RC replication over the past twenty years. Regulation of replication of RCR plasmids will not be included since it is the subject of another review.

    2015-04-01

    The field of Physics Education Research (PER) has for over thirty years provided insights into student thinking and guided the development and assessment of reformed teaching strategies and practices in introductory physics courses. In the last decade or so, researchers have expanded the domain of such investigations to upper-division courses where undergraduate majors study more advanced content and begin to see themselves as future physicists. The upcoming Focused Collection on Upper Division PER brings together work from researchers active in these new frontiers of PER. In this presentation we provide an overview of the studies in this collection, which offer to the PER and greater physics education communities: new insights about the thinking, behavior, and beliefs of students in the upper division; new tools to innovate instruction, assess student learning, and evaluate teaching effectiveness; and groundbreaking studies of identity development and ``thinking like a physicist'' among physics majors. In this session we also recognize the ten-year anniversary of Physical Review Special Topics: Physics Education Research, an occasion that we will celebrate with an informal reception immediately following the conclusion of this invited session.

    2012-02-01

    Microstructure determines the yield of free charge in neat semiconducting polymers. Understanding the fundamental photophysics of poly(3-hyxylthiophene) films, and that of conjugated polymers in general, is essential if we are to realize their full potential as low-cost active layers for coal-competitive solar power generation. Yet, the value of one of the most basic photophysical parameters of these materials - the yield of free charges upon photoexcitation of neat films - has remained controversial because of a wide variation between previous measurements. Researchers at the National Renewable Energy Laboratory (NREL) have resolved this controversy by showing that the yield of free charges depends sensitively on the solid-state microstructure of the film. The microstructure was varied systematically through control of the polymers molecular weight and processing conditions, while the charge carrier yield was measured using time-resolved microwave conductivity - a unique technique to which only a few groups in the world have access. The researchers found that the yield of long-lived free charges depends on the co-existence of amorphous and crystalline domains in the polymer, and this behavior was attributed to charge separation at the interface between these two domains of order.

    Retinal oximeter is a new machine which has been used in the diagnose, treatment and research of several ophthalmic diseases for recent years. It allows ophthalmologists to gain retinal oxygen saturation directly. Therefore, retinal oximeter might be useful for ophthalmologists to understand ophthalmic diseases more deeper and clarify the impact of ischemia on retinal function. It has been reported in the literatures that retinal oximeter has potentially useful diagnostic and therapeutic indications in various eye diseases such as diabetic retinopathy, central retinal vein and artery occlusion, retinitis pigmentosa, glaucomatous optic neuropathy, et al. In this thesis, the application of retinal oximeter in ophthalmology is reviewed.

    2017-01-01

    Big data clinical research typically involves thousands of patients and there are numerous variables available. Conventionally, these variables can be handled by multivariable regression modeling. In this article, the hierarchical cluster analysis (HCA) is introduced. This method is used to explore similarity between observations and/or clusters. The result can be visualized using heat maps and dendrograms. Sometimes, it would be interesting to add scatter plot and smooth lines into the panels of the heat map. The inherent R heatmap package does not provide this function. A series of scatter plots can be created using lattice package, and then background color of each panel is mapped to the regression coefficient by using custom-made panel functions. This is the unique feature of the lattice package. Dendrograms and color keys can be added as the legend elements of the lattice system. The latticeExtra package provides some useful functions for the work. PMID:28275620

  16. The microstructure of polar ice. Part I: Highlights from ice core research

    NASA Astrophysics Data System (ADS)

    Faria, Sérgio H.; Weikusat, Ilka; Azuma, Nobuhiko

    2014-04-01

    Polar ice sheets play a fundamental role in Earth's climate system, by interacting actively and passively with the environment. Active interactions include the creeping flow of ice and its effects on polar geomorphology, global sea level, ocean and atmospheric circulation, and so on. Passive interactions are mainly established by the formation of climate records within the ice, in form of air bubbles, dust particles, salt microinclusions and other derivatives of airborne impurities buried by recurrent snowfalls. For a half-century scientists have been drilling deep ice cores in Antarctica and Greenland for studying such records, which can go back to around a million years. Experience shows, however, that the ice-sheet flow generally disrupts the stratigraphy of the bottom part of deep ice cores, destroying the integrity of the oldest records. For all these reasons glaciologists have been studying the microstructure of polar ice cores for decades, in order to understand the genesis and fate of ice-core climate records, as well as to learn more about the physical properties of polar ice, aiming at better climate-record interpretations and ever more precise models of ice-sheet dynamics. In this Part I we review the main difficulties and advances in deep ice core drilling in Antarctica and Greenland, together with the major contributions of deep ice coring to the research on natural ice microstructures. In particular, we discuss in detail the microstructural findings from Camp Century, Byrd, Dye 3, GRIP, GISP2, NorthGRIP, Vostok, Dome C, EDML, and Dome Fuji, besides commenting also on the earlier results of some pioneering ventures, like the Jungfraujoch Expedition and the Norwegian-British-Swedish Antarctic Expedition, among others. In the companion Part II of this work (Faria et al., 2014), the review proceeds with a survey of the state-of-the-art understanding of natural ice microstructures and some exciting prospects in this field of research.

    The FP7 DRIHM (Distributed Research Infrastructure for Hydro-Meteorology, http://www.drihm.eu, 2011-2015) project intends to develop a prototype e-Science environment to facilitate the collaboration between meteorologists, hydrologists, and Earth science experts for accelerated scientific advances in Hydro-Meteorology Research (HMR). As the project comes to its end, this presentation will summarize the HMR results that have been obtained in the framework of DRIHM. The vision shaped and implemented in the framework of the DRIHM project enables the production and interpretation of numerous, complex compositions of hydrometeorological simulations of flood events from rainfall, either simulated or modelled, down to discharge. Each element of a composition is drawn from a set of various state-of-the-art models. Atmospheric simulations providing high-resolution rainfall forecasts involve different global and limited-area convection-resolving models, the former being used as boundary conditions for the latter. Some of these models can be run as ensembles, i.e. with perturbed boundary conditions, initial conditions and/or physics, thus sampling the probability density function of rainfall forecasts. In addition, a stochastic downscaling algorithm can be used to create high-resolution rainfall ensemble forecasts from deterministic lower-resolution forecasts. All these rainfall forecasts may be used as input to various rainfall-discharge hydrological models that compute the resulting stream flows for catchments of interest. In some hydrological simulations, physical parameters are perturbed to take into account model errors. As a result, six different kinds of rainfall data (either deterministic or probabilistic) can currently be compared with each other and combined with three different hydrological model engines running either in deterministic or probabilistic mode.

    Fifteen years ago, Tom Moon wrote a review on this journal in order to propose some explanations to the exacerbated glycaemic response after a glucose load or a carbohydrate meal intake observed in fish, the so-called intolerance to glucose. Before, but in most of cases after this paper, several laboratories worldwide started to make important efforts in order to better understand this strange phenotype observed in fish and that so far seemed to belong to diabetic humans only. Tom had been worked on fish metabolism for at least 30years when he proposed that mini-review and the paths opened by him in 2001 were followed by tens of fish researchers, making this paper a breaking point on the field. Fifteen years later, we propose not only to have a look to the answers given to the questions rose in that paper, but also to summarize how his career over all these years impacted the domain of glucose metabolism in fish. In the review, we will show how Tom Moon analysed at different levels (from genes up to the whole organism), using distinct experimental tools (cells, hormone or glucose injection, pumps, drugs) the questions of glucose metabolism, tolerance and nutrition in fish species.

    The Varroa mite (Varroa destructor) is implicated as a major disease factor in honey bee (Apis mellifera) populations worldwide. Honey bees are extensively relied upon for pollination services, and in countries such as New Zealand and Australia where honey bees have been introduced specifically for commercial pollinator services, the economic effects of any decline in honey bee numbers are predicted to be profound. V. destructor established in New Zealand in 2000 but as yet, Australia remains Varroa-free. Here we analyze the history of V. destructor invasion and spread in New Zealand and discuss the likely long-term impacts. When the mite was discovered in New Zealand, it was considered too well established for eradication to be feasible. Despite control efforts, V. destructor has since spread throughout the country. Today, assessing the impacts of the arrival of V. destructor in this country is compromised by a paucity of data on pollinator communities as they existed prior to invasion. Australia's Varroa-free status provides a rare and likely brief window of opportunity for the global bee research community to gain understanding of honey bee-native pollinator community dynamics prior to Varroa invasion.

    This is a review education paper on the current ophthalmology simulators utilized worldwide for undergraduate and postgraduate training. At present, various simulators such as the EYE Exam Simulator (Kyoto Kagaku Co. Ltd., Kyoto, Japan), Eyesi direct ophthalmoscope simulator (VRmagic, GmbH, Mannheim, Germany), Eyesi indirect ophthalmoscope simulator (VRmagic, GmbH, Mannheim, Germany) and Eyesi cataract simulators (VRmagic, GmbH, Mannheim, Germany). These simulators are thought to be able to reduce the initial learning curve for the ophthalmology training but further research will need to be conducted to assess the effectiveness of the simulation-assisted Ophthalmology training. Future research will be of great value to assess the medical students and residents' responses and performance regarding the usefulness of the individual eye simulator. PMID:27366698

    The Centennial Meeting of the American Association for Cancer Research (AACR) was held from 14-18 April 2007 at the Los Angeles Convention Center. This meeting brought together a diverse group of over 18 000 researchers working in the fields of basic and applied cancer sciences, and explored how cancer research could be used most effectively to prevent and cure cancer at the earliest possible stage. The goal of the AACR Annual Meeting was to stimulate the dialog between basic and clinical researchers so that the translation of new discoveries might be speeded up for the benefit of cancer patients. Advances in the clinical application of genomics, epigenomics and proteomics to diagnose, monitor and prognosticate cancer development led to a dramatic increase in the number of presentations with a translational focus at this year's meeting. Several remarkable areas were particularly highlighted in this report, including The Cancer Genome Atlas, cancer stem cells, microRNA and siRNA, targeted therapy and individualized treatment. This article tries to bring attention to some hot topics in the program that are both new and noteworthy. For those who did not attend the meeting, this report may serve as a highlight of this important international cancer research meeting.

    Objective To determine the factors most important to applicants when selecting an ophthalmology residency program. Design Cross-sectional survey. Participants All 595 applicants who submitted a rank list to the Ophthalmology Residency Matching Program for the 2012 match. Methods Participants anonymously completed a 25-item questionnaire after the submission of their rank lists. A multiple-choice format and ordinal scale were used to query applicants on demographics, career plans, and the importance of factors related to program characteristics. One question allowed a free text response to identify factors that caused the applicant to rank a program lower than other programs or not at all (i.e., “red flag”). Main Outcome Measures Factors important to applicants when creating their rank lists. Results The response rate was 37% (218/595). The 3 most important factors affecting rank lists were resident–faculty relationships, clinical and surgical volume, and diversity of training. The fourth most important was the interview experience with faculty; poor interview experience was the most frequently cited “red flag.” Age, gender, and marital status did not affect how applicants rated factors. Applicants planning a post-residency fellowship or an academic career placed greater importance on opportunities for resident research and a program's prestige (P<0.0001). Female and ethnic minority applicants placed greater importance on the diversity of faculty and residents by gender or ethnicity (P<0.0001). Conclusions Applicants rated educational and interpersonal factors as more important than geographic factors when selecting an ophthalmology residency program. Future career plans and demographic factors influenced the rating of specific factors. The results of this study provide a useful resource to programs preparing for the match. PMID:23084123

    Measurements in ophthalmic research may be of parameters such as visual functions, quality of life or physical measures and can involve different types of instruments such as questionnaires and mechanical, chemical or electronic devices. Whatever the mode of measurement, however, all these devices require sufficient evidence for validity before inferences can be made on the basis of their findings. This article explores the nature and often overlooked importance of validity and explains some of the terminology involved. It discusses the main forms that ophthalmologists should be aware of before they can assess whether the instruments, old and new, are providing results upon which inferences can be made with any level of confidence. The literature search involved use of Medline, PubMed and Ovid as well as referenced papers in journals and books. Searches were comprehensive and international. Foreign texts were translated.

    Many of today's important ophthalmic pharmaceuticals have a rich ethnobotanical history. Solanaceous plants, the source of atropine, have contributed to medical therapy since the beginning of Western civilization. The botanical source of physostigmine played a pivotal role as an ordeal poison in the culture of Old Calabar, West Africa. Native peoples of Amazonia treasured plants containing pilocarpine as panaceas because of their impressive diaphoretic effect. Nineteenth century scientists examining these plants because of their folkloric reputations discovered their active compounds and documented their physiological effects. Ophthalmologists such as Argyll Robertson, Laqueur, and Weber built upon this research to bring these pharmaceuticals into therapeutic use. The ongoing loss of the world's tropical rain forests threatens to destroy a vast storehouse of untested biological compounds.

    Simulation can be defined as malingering, or sometimes functional visual loss (FVL). It manifests as either simulating an ophthalmic disease (positive simulation), or denial of ophthalmic disease (negative simulation). Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today's world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician's responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test(s) to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of optical coherence tomography, frequency doubling perimetry (FDP), and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up-to-date information on malingering or simulation in ophthalmology. PMID:24195054

    Although the incidence of cancer and cancer related deaths in the United States has decreased over the past two decades due to improvements in early detection and treatment, cancer still is responsible for a quarter of the deaths in this country. There is much room for improvement on the standard treatments currently available and the National Cancer Institute (NCI) has recognized the potential for nanotechnology and nanomaterials in this area. The NCI Alliance for Nanotechnology in Cancer was formed in 2004 to support multidisciplinary researchers in the application of nanotechnology to cancer diagnosis and treatment. The researchers in the Alliance have been productive in generating innovative solutions to some of the central issues of cancer treatment including how to detect tumors earlier, how to target cancer cells specifically, and how to improve the therapeutic index of existing chemotherapies and radiotherapy treatments. Highly creative ideas are being pursued where novelty in nanomaterial development enables new modalities of detection or therapy. This review highlights some of the innovative materials approaches being pursued by researchers funded by the NCI Alliance. Their discoveries to improve the functionality of nanoparticles for medical applications includes the generation of new platforms, improvements in the manufacturing of nanoparticles and determining the underlying reasons for the movement of nanoparticles in the blood.

    The capture and integration of structured ophthalmologic data into electronic health records (EHRs) has historically been a challenge. However, the importance of this activity for patient care and research is critical. The purpose of this study was to develop a prototype of a context-driven dynamic extensible markup language (XML) ophthalmologic data capture application for research and clinical care that could be easily integrated into an EHR system. Stakeholders in the medical, research, and informatics fields were interviewed and surveyed to determine data and system requirements for ophthalmologic data capture. On the basis of these requirements, an ophthalmology data capture application was developed to collect and store discrete data elements with important graphical information. The context-driven data entry application supports several features, including ink-over drawing capability for documenting eye abnormalities, context-based Web controls that guide data entry based on preestablished dependencies, and an adaptable database or XML schema that stores Web form specifications and allows for immediate changes in form layout or content. The application utilizes Web services to enable data integration with a variety of EHRs for retrieval and storage of patient data. This paper describes the development process used to create a context-driven dynamic XML data capture application for optometry and ophthalmology. The list of ophthalmologic data elements identified as important for care and research can be used as a baseline list for future ophthalmologic data collection activities.

    Over the past seven years, NASA's Sun-Earth Connection Education Forum has sponsored and coordinated education and public outreach events to highlight NASA's heliophysics research and discoveries. Our strategy involves using celestial events, such as total solar eclipses and the Transit of Venus, as well as Sun-Earth Day during the March Equinox, to engage K-12 schools and the general public in space science activities, demonstrations, and interactions with space scientists. In collaboration with partners that include the Exploratorium and other museums, Ideum, NASA TV, NASA heliophysics missions, and others, we produce webcasts, other multi-media, and print resources for use by school and informal educators nation-wide and internationally. We provide training and professional development to K-12 educators, museum personnel, amateur astronomers, Girl Scout leaders, etc., so they can implement their own outreach programs taking advantage of our resources. A coordinated approach promotes multiple programs occurring each year under a common theme. As part of an Ancient Observatories theme in 2005, we have successfully featured solar alignments with ancient structures made by indigenous cultures that mark the equinoxes and/or solstices in cultural and historical parks in the Americas. In partnership with the Exploratorium, we produced broadcast-quality and webcast programming during the March equinox that shared heliophysics within a broad cultural context with formal and informal education audiences internationally. The program: "Descent of the Serpent" featured the light and shadow effect at sunset that takes place during the spring equinox at the Pyramid of El Castillo, in Chichén Itzá (México). This program made unique and authentic cultural connections to the knowledge of solar astronomy of the Maya, the living Mayan culture of today, and the importance of the Sun across the ages.

    1992-03-01

    In 1961, one year after its invention, the laser was used for experimental photocoagulation in animals. In 1963 it was tried for treatment of human eyes. Due to the fact that the optical media in the eye are transmissible to light, the laser offers the unique possibility of measuring and manipulating within a very strict localization without opening the eye. The properties of laser light are increasingly exploited for diagnostics in ophthalmic disease. The introduction of the laser as a tool in ophthalmology has revolutionized ophthalmic treatment. Unfortunately, it has been pointed out in international peace meetings that the biological effect evoked by lasers can also be used for intentional destruction of the vision of enemy soldiers. To prevent such an abuse of lasers against eyes, a strong formal international anti-laser weapon movement has been initiated.

    Understanding outcomes of pediatric malpractice litigation allows ophthalmologists to gain insight into how to best care for patients and prevent such litigation. To report and analyze the causes and outcomes of ophthalmology medical malpractice litigation involving patients younger than 18 years. The WestLaw database was reviewed from April 1 to 30, 2015, for ophthalmology-related lawsuits, including settlements and trial verdicts, in the United States from January 1, 1930, to December 31, 2014. Search terms included ophthalmology or ophthalmologist and malpractice anywhere in the retrieved documents. Cases in which the plaintiffs were younger than 18 years at the time of the inciting event were included. Pediatric cases were compared with adult cases. Pediatric malpractice case outcomes and settlement amounts. Sixty-eight ophthalmology malpractice cases involving plaintiffs younger than 18 years were included in the study. Thirty-five cases (51.5%) were resolved via jury trial. Of these 35 cases, verdicts in favor of the plaintiff were issued in 17 pediatric cases (48.6%), compared with 168 of 584 adult cases (28.8%) (difference, 33%; 95% CI, -24% to 64%; P = .01). The 17 cases that resulted in verdicts in favor of the pediatric plaintiff had a mean jury award of $4 815 693 (median, $883 281; range, $147 765-$42 061 690). Nine of the total 68 cases (13.2%) resulted in a settlement, with mean adjusted indemnities of $1 912 738 (median, $1 377 689; range, $92 070-$8 493 086). The remaining 24 cases (35.3%) involved appellate rulings, pretrial and posttrial relief rulings, and 1 bench verdict. Jury awards were higher in pediatric vs adult cases (difference, $3 422 134; 95% CI, -$3 422 134 to $8 731 916; P = .002), as were indemnity payments (difference, $1 186 757; 95% CI, -$69 074 to $3 342 588; P = .003).

In outcomes research, one modern initiative has been to conduct holistic measurement of outcomes inclusive of the patient's point of view; patient-centred outcome. This, of course, means including a questionnaire. However, the irony of trying to improve outcomes research by being inclusive of many measures is that the researcher may not be expert in all measures used. Certainly, few people conducting outcomes research in ophthalmology would claim to be questionnaire experts. Most tend to be experts in their ophthalmic subspecialty and probably simply choose a popular questionnaire that appears to fit their needs and think little more about it. Perhaps, unlike our own field, we assume that the field of questionnaire research is relatively stable. This is far from the case. The measurement of patient-centred outcomes with questionnaires is a rapidly evolving field. Indeed, over the last few years a paradigm shift has occurred in patient-centred measurement.

Ophthalmologists who have received a K award from 1996 through 2010. K08 and K23 grant awardees were identified through the NIH Research Portfolio Online Reporter database. Information including gender, institution, educational degrees, and success in obtaining an R01 grant was analyzed. Receipt of an R01 grant. One hundred five ophthalmologists were identified who received K08 or K23 grants from the National Eye Institute from 1996 through 2010. Overall, 75% of these were male, although 43% of K awardees were women from 2006 through 2010. Sixty-five percent (68/105) of individuals came from ophthalmology departments that ranked in the top 20 of NIH funding in 2010. The most predominant subspecialties represented were retina (32%), cornea (22%), and glaucoma (15%). Among the K awardees, 40% (42/105) had a doctor of philosophy (PhD) degree in addition to their medical doctor degree. From 1996 through 2000, 61% (23/38) were successful in obtaining an R01 grant, whereas only 13% (5/39) from 2001 through 2005 obtained R01 grants (P<0.001). Gender disparities exist among K awardees in ophthalmology, but these seem to be improving over time. None of the other variables studied-gender, PhD degree, specialty, or funding tier-was associated with obtaining R01 funding. This study helps to characterize the clinician-scientist cohort in ophthalmology and to identify areas to improve the recruitment of these individuals.

    To determine the percentage of publication misrepresentation among applicants to an ophthalmology residency, to compare that percentage with published percentages from other specialties, and to compare the number of US-trained applicants vs non-US-trained applicants found to misrepresent published articles. Published articles in peer-reviewed journals listed on residency applications to the Jones Eye Institute from October 10, 2000, to December 1, 2004, were searched, excluding applications that were unavailable or were from current residents and faculty. The type of misrepresentation of published articles and the country of medical school training were recorded. Compared were US-trained applicants vs non-US-trained applicants to determine which group was more likely to list published articles and which group was more likely to have a misrepresented published article. Eight hundred twenty-one of 852 applications (96.4%) were reviewed. Five hundred fifty applicants (67.0%) were from US medical schools, and 271 applicants (33.0%) were from non-US medical schools. Two hundred one applicants (24.5%) listed peer-reviewed published articles. Misrepresentation of published articles was found in 15 applicants (5 US trained and 10 non-US trained). The mean percentage of applicants with misrepresentation per applicant pool was 1.9%, while the mean percentage per applicants listing published articles was 8.1%. The most common misrepresentation found was self-promotion on the author list (50.0%), followed by omission of other authors (25.0%), nonexistent articles (12.5%), and nonauthorship (12.5%). Foreign medical graduates were more likely to list published articles (P = .008) and to have a misrepresented published article (P = .01). Ophthalmology has one of the lowest reported percentages of applicant publication misrepresentation in the literature. Foreign medical graduates were more likely to list published articles and to misrepresent published articles. Self-promotion on

    The authors review the utility of genetic testing in ophthalmic disorders - precise diagnosis, accurate prognosis, genetic counseling, prenatal diagnosis, and entry into gene-specific therapeutic trials. The prerequisites for a successful outcome of a genetic test are an accurate clinical diagnosis, a careful family history that guides which genes to study, and genetic counseling (both pre-test and post-test). The common eye disorders for which genetic testing is commonly requested are briefly discussed - anophthalmia, microphthalmia, coloboma, anterior segment dysgenesis, corneal dystrophies, cataracts, optic atrophy, congenital glaucoma, congenital amaurosis, retinitis pigmentosa, color blindness, juvenile retinoshisis, retinoblastoma etc. A protocol for genetic testing is presented. If specific mutations in a gene are common, they should form the first tier test, as the mutations in Leber hereditary optic neuropathy. If mutations in one gene are likely, sequencing of that gene should be carried out, e.g. GALT gene in galactosemia, RS1 gene in retinoshisis. Disorders with genetic heterogeneity require multi-gene panel tests, and if these show no abnormality, then deletion / duplication or microarray studies are recommended, followed in sequence by clinical exome (5000 to 6000 genes), full exome (about 20,000 genes or whole genome studies (includes all introns). It is fortunate that most genetic tests in ophthalmology are available in India, including gene panel and whole exome/genome sequencing tests.

    Curcumin (diferuloylmethane) is the main curcuminoid of the popular Indian spice turmeric (Curcuma longa). In the last 50 years, in vitro and in vivo experiments supported the main role of polyphenols and curcumin for the prevention and treatment of many different inflammatory diseases and tumors.The anti-inflammatory, antioxidant, and antitumor properties of curcumin are due to different cellular mechanisms: this compound, in fact, produces different responses in different cell types. Unfortunately, because of its low solubility and oral bioavailability, the biomedical potential of curcumin is not easy to exploit; for this reason more attention has been given to nanoparticles and liposomes, which are able to improve curcumin's bioavailability. Pharmacologically, curcumin does not show any dose-limiting toxicity when it is administered at doses of up to 8 g/day for three months. It has been demonstrated that curcumin has beneficial effects on several ocular diseases, such as chronic anterior uveitis, diabetic retinopathy, glaucoma, age-related macular degeneration, and dry eye syndrome. The purpose of this review is to report what has so far been elucidated about curcumin properties and its potential use in ophthalmology.

    So far it has not been possible to adapt man genetically to the specific environmental conditions of flying. A variety of disturbing factors act on the human body and affect its vital as well as sensory functions, vision being considered the most important sense for providing information. The effects of oxygen deficiency caused by increasing altitude, acceleration and centrifugal force affecting visual function, ocular motility, and pupillary reactions are well known. Like visual illusions, vibrations, high accelerative forces, high illuminance and glare at high altitudes impair the visual perception of the environment. In space flight further problems ensue from weightlessness and short-wave radiation. The high medical standards that must be met by the eyes of flying personnel, as will as for air-traffic controllers, result in the enhancement of flight safety. After operations on the cornea or retina or cataract operations in pilote, the retinal findings and DOP must be monitored closely. Special attention must be paid to means of visual aids, corrective lenses, contact lenses, and intraocular lenses. Ophthalmology is a very important element of aviation and aerospace medicine.

    To diagnose a patient with a failing visual system, it is necessary to localize the site of the lesion in the system, and identify the etiology that has produced it. Physicians do not see diseases but just their manifestations. Clinical neuro-ophthalmology provides the basic principles on how to progress from manifestations to the diseases they indicate. The Frank B. Walsh Neuro-Ophthalmology Society (the Walsh Society) that originated in 1969 in the United States has been the center of clinical neuro-ophthalmology case studies throughout the world. In Japan, the Ronald M. Burde Clinical Neuro-Ophthalmology Study Group (the RMB Society) was organized in 2001 to establish and promote a clinicopathologic conference in the style of the Walsh Society. On this occasion, Prof. Burde was invited to the Annual Japanese Ophthalmological Society meeting. Based on some illustrative cases presented at the annual meetings of the RMB society, this review was carried out to present the current knowledge of clinical neuro-ophthalmology.

    To assess current global health education and international electives in ophthalmology residency programs and barriers to global health implementation in ophthalmology resident education. A web-based survey regarding participation in global health and international electives was emailed to residency program directors at 116 accredited ophthalmology residency programs via an Association of University Professors in Ophthalmology (AUPO) residency program director listserv. Fifty-nine (51%) ophthalmology residency program directors responded. Thirty-seven program directors (63%) said global health was important to medical students when evaluating residency programs. Thirty-two program directors (55%) reported developing international electives. Reported barriers to resident participation in international electives were: 1) insufficient financial support, 2) inadequate resident coverage at home, and 3) lack of ACGME approval for international electives. Program directors requested more information about resident international electives, funding, and global ophthalmology educational resources. They requested ACGME recognition of international electives to facilitate resident participation. More than half (54%) of program directors supported international electives for residents. This survey demonstrates that program directors believe global health is an important consideration when medical students evaluate training programs. Despite perceived barriers to incorporating global health opportunities into residency training, program directors are interested in development of global health resources and plan to further develop global health opportunities.

    Since the discovery of the structure of DNA in 1953 by Watson and Crick, our understanding of the genetic causes and the regulations involved in tumor development have hugely increased. The important amount of research developed since then has led to the development of gene therapy, which specifically targets and treats cancer cells by interacting with, and correcting their genetic material. This study is a review of the most accomplished research using gene therapy aimed at treating malignant ophthalmologic diseases, and focuses more specifically on uveal melanoma and retinoblastoma. Such approaches are remarkable regarding the efficiency and the cellular targeting specificity. However, gene therapy-based treatments are so recent that many long-term interrogations subsist. The majority of the reviewed studies are conducted in vitro or in murine models, thereby requiring several years before the resulting therapies become part of the daily ophthalmologists' arsenal. However, the recent spectacular developments based on advanced scientific knowledge justify an up-to-date review that would benefit the ophthalmologist community.

    Stomatognathic system is strictly correlated to other anatomical regions; many studies investigated relationship between temporomandibular joint and posture, several articles describe cranio-facial pain from dental causes, such as trigger points. Until now less interest has been given to connections between dental occlusion and ophthalmology, even if they are important and involving. Clinical experience in dental practice claims that mandibular latero-deviation is connected both to eye dominance and to defects of ocular convergence. The trigeminal nerve is the largest and most complex of the twelve cranial nerves. The trigeminal system represents the connection between somitic structures and those derived from the branchial arches, collecting the proprioception from both somitic structures and oculomotor muscles. The intermedius nucleus of the medulla is a small perihypoglossal brainstem nucleus, which acts to integrate information from the head and neck and relays it on to the nucleus of the solitary tract where autonomic responses are generated. This intriguing neurophysiological web led our research group to investigate anatomical and functional associations between dental occlusion and vision. In conclusion, nervous system and functional pathways strictly connect vision and dental occlusion, and in the future both dentists and oculists should be more and more aware of this correlation for a better diagnosis and therapy.

  3. The Neuro-Ophthalmology of Mitochondrial Disease

    2010-01-01

    Mitochondrial diseases frequently manifest neuro-ophthalmologic symptoms and signs. Because of the predilection of mitochondrial disorders to involve the optic nerves, extraocular muscles, retina, and even the retrochiasmal visual pathways, the ophthalmologist is often the first physician to be consulted. Disorders caused by mitochondrial dysfunction can result from abnormalities in either the mitochondrial DNA or in nuclear genes which encode mitochondrial proteins. Inheritance of these mutations will follow patterns specific to their somatic or mitochondrial genetics. Genotype-phenotype correlations are inconstant, and considerable overlap may occur among these syndromes. The diagnostic approach to the patient with suspected mitochondrial disease entails a detailed personal and family history, careful ophthalmic, neurologic, and systemic examination, directed investigations, and attention to potentially life-threatening sequelae. Although curative treatments for mitochondrial disorders are currently lacking, exciting research advances are being made, particularly in the area of gene therapy. Leber hereditary optic neuropathy, with its window of opportunity for timely intervention and its accessibility to directed therapy, offers a unique model to study future therapeutic interventions. Most patients and their relatives benefit from informed genetic counseling. PMID:20471050

    Future ophthalmologists will need to have broad skills to thrive in complex health care organizations. However, training for ophthalmologists does not take advantage of all of the postgraduate years (PGYs). Although the traditional residency years seem to have little excess capacity, enhancing the internship year does offer an opportunity to expand the time for ophthalmology training in the same 4 PGYs. Integrating the internship year into residency would allow control of all of the PGYs, allowing our profession to optimize training for ophthalmology. In this white paper, we propose that we could capture an additional 6 months of training time by integrating basic ophthalmology training into the intern year. This would allow 6 additional months to expand training in areas such as quality improvement or time for "mini-fellowships" to allow graduates to develop a deeper set of skills.

    To test whether there is an association between the growth in the number of ophthalmic journals in the past years and their mean and maximum impact factor (IF) as a common sign of scientific proliferation. Using data from the 2013 Journal Citation Report database a study of the major clinical medical fields was conducted to assess the correlation between the number of journals and maximum IF in a given field in the year 2013. In the field of ophthalmology, we examined the correlation between year, number of journals, mean IF and maximum IF in the field of ophthalmology throughout the years 2000-2013. In the major medical fields, a positive correlation was found between the number of journals and the maximum IF (quadratic R2 = 0.71, P< 0.001). When studying the field of ophthalmology a positive correlation between the number of journals and mean IF (R2 = 0.84, P< 0.001) and between number of journals and maximum IF (R2 = 0.71, P< 0.001) was detected. Our findings suggest that the variation in the IF can be explained by the number of journals in the field of ophthalmology. In the future, the formation of additional ophthalmology journals is likely to further increase the IFs of existing journals.

    ABSTRACT Purpose To ascertain the extent to which ophthalmologic interventions have been evaluated in value-based medicine format. Methods Retrospective literature review. Papers in the healthcare literature utilizing cost-utility analysis were reviewed by researchers at the Center for Value-Based Medicine, Flourtown, Pennsylvania. A literature review of papers addressing the cost-utility analysis of ophthalmologic procedures in the United States over a 12-year period from 1992 to 2003 was undertaken using the National Library of Medicine and EMBASE databases. The cost-utility of ophthalmologic interventions in inflation-adjusted (real) year 2003 US dollars expended per quality-adjusted life-year ($/QALY) was ascertained in all instances. Results A total of 19 papers were found, including a total of 25 interventions. The median cost-utility of ophthalmologic interventions was $5,219/QALY, with a range from $746/QALY to $6.5 million/QALY. Conclusions The majority of ophthalmologic interventions are especially cost-effective by conventional standards. This is because of the substantial value that ophthalmologic interventions confer to patients with eye diseases for the resources expended. PMID:15747756

    Human ingenuity is challenged by defending vision, our highest bandwidth sense. Special challenges are presented by the replacement or repair of highly specialized but scarce tissue within the constraints of transparency, tissue shape and alignment, tissue borders and pressure maintenance. Many, mostly destructive, surgical procedures were developed prior to an understanding of underlying pathophysiology. For a number of conditions, both reconstructive and destructive procedures co-exist, yet there are few guidelines as to the better approach. Because the consequences of these procedures may take many years to surface (consistent with a stem cell role in long-term tissue maintenance), guidance may be provided by the elucidation of underlying principles from these approaches. Illustrative examples from clinical, basic research and biotechnology, particularly relating to pterygium, ocular surface squamous neoplasia, dry-eye syndrome, corneal rehabilitation and replacement, cataract surgery, strabismus surgery and bionic eye research, are described. An unexpected consequence of bionic device development has been an appreciation of the sophistication of tissues being replaced, given the limitations of available biomaterials. Examples of how this has provided insights into ocular disease will be illustrated. Stem cell and biomaterial technologies are starting to impact at a time when cost-effectiveness is under scrutiny. Both efficacy and cost will need to be considered as these interventions are introduced. It appears that the paradigm shift rate is accelerating and there is evidence of this in ophthalmology. Lessons learned from the areas of destructive versus reconstructive surgery and the limitations of development of bionic replacements will be used to illustrate how new procedures and technologies can be developed. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

    Studying of functional aspects of eye disease pathogenesis by electrophysiological methods is widely demanded in fundamental ophthalmology. Introduction of modern methods of functional assessment into experimental and clinical projects significantly broadens knowledge of normal and pathological functioning of the visual system and is the basis for further development of new strategies of pathogenetic treatment, diagnostics and expert evaluation. Some problems of ophthalmology, including those that concern age-related macular degeneration, glaucoma, diabetic retinopathy, and other diseases, are considered in the context of how much electrophysiology contributes to their solution. The role of functional examinations of the retina in studying pathophysiology of neurodegenerative brain diseases, such as Alzheimer's and Parkinson's, is also discussed.

    To assess the publication volume of Canadian ophthalmology departments over a 5-year period, 2005-2009. Systematic review of the literature. MEDLINE was searched for papers published from 2005 to 2009 where the designated affiliation corresponded to a Canadian ophthalmology department. The papers were sorted by year, university, and study design. A total impact score (the impact factor of the journal multiplied by the number of papers published in that journal per year) was also calculated for each university. In the 5-year period there was an increasing trend in the total number of published ophthalmology papers. The University of Toronto had the highest number of published papers (224), followed by the University of British Columbia (143) and McGill University (120). The Canadian Journal of Ophthalmology published the most papers, followed by Investigative Ophthalmology and Visual Science. The most frequent study design category was basic science research and a total of 11 different randomized controlled trials were retrieved. The publication volume of Canadian ophthalmology researchers increased significantly from 2005 to 2009 with larger institutions accounting for the majority of published papers. Like researchers in other countries, Canadian ophthalmology researchers preferred to publish in domestic journals.

    The radio astronomy group at the Tokyo Astronomical Observatory was founded in 1948 immediately after WWII, and decided to put its main research efforts into solar radio astronomy. The first radio telescope was completed in 1949 and started routine observations at 200 MHz. Since then, the group has placed its emphasis on observations at meter and decimeter wavelengths, and has constructed various kinds of radio telescopes and arrays operating at frequencies ranging from 60 to 800 MHz. In addition, radio telescopes operating at 3, 9.5 and 17 GMHz were constructed. In parallel with the observationally-based research, theoretical research on solar radio emission also was pursued. In this paper, we review the instrumental, observational and theoretical developments in solar radio astronomy at the Tokyo Astronomical Observatory in the important period from 1949 through to the 1960s.

    Within the frame of the international field campaign COPS (Convective and Orographically-induced Precipitation Study), a large suite of state-of-the-art meteorological instrumentation was operated, partially combined for the first time. The COPS field phase was performed from 01 June - 31 August 2007 in a low-mountain area in southwestern Germany/eastern France covering the Vosges Mountains, the Rhine valley and the Black Forest Mountains. The collected data set covers the entire evolution of convective precipitation events in complex terrain from their initiation, to their development and mature phase up to their decay. 18 Intensive Operation Periods (IOPs) with 34 operation days and 8 additional Special Observation Periods (SOPs) were performed providing a comprehensive data set covering different forcing conditions. In this paper an overview of the COPS scientific strategy, the field phase, and its first accomplishments is given. Some highlights of the campaign are illustrated with several measurement examples. It is demonstrated that COPS provided new insight in key processes leading to convection initiation and to the modification of precipitation by orography, in the improvement of QPF by the assimilation of new observations, and in the performance of ensembles of convection permitting models in complex terrain.

    Organized health services in Bosnia and Herzegovina started with the foundation of several vakuf hospitals (in Sarajevo, Tuzla, Banja Luka, Mostar and Travnik) financed by the fund of the Gazi Husrev-beg vakuf. In these hospitals services was provided by the qualified health professionals, mainly educated at the schools of medicine in Turkey, Italy, Austria, Hungary, Switzerland and other countries. Majority of them worked as civil and military physicians in the above mentioned vakuf hospitals, but also in the Turkey army hospitals situated in the all larger settlements in Bosnia and Herzegovina. During the period when B&H was managed by the Turkey and Austro-Hungarian empire there was no specialized ophthalmology services. During the Austro-Hungarian management there was a Surgical-oculist department within the Land Hospital in Sarajevo, which treated 4.47% of patients with eye diseases, among total number of in-patients, and according to the health service at the end of year 1900, during that year there there was 3238 general surgeries and 633 ophthalmology surgeries performed. In the Kingdom of Yugoslavia, beside establishment of the independent Eye department within the General State hospital in Sarajevo, in1923, also started development of the ophthalmology service within Surgical Department in Mostar, which was lead in 1929 by the ophthalmologist, and which grew in 1931 into independent Eye Department, as the second of that type in B&H. Specialized ophthalmology service in Banja Luka started to develop within the Surgery Department in 1931, and independent Eye Department was founded in 1945. Medical Faculty in Sarajevo was founded on 16th November 1946. Also on founded on the same day is the Eye Clinic, and appointed as its first director was Professor Vladimir Cavka MD., one of the first full time professors of the Medical Faculty in Sarajevo, founder of the Peoples society of B&H (Academy of Sciences and Arts of B&H) and the magazine, Medicinski arhiv

    Sarcopenia and cachexia are significant medical problems with a high disease related burden in cardiovascular illness. Muscle wasting and weight loss are very frequent particularly in chronic heart failure and they relate to poor prognosis. Although clinically largely underestimated, the fields of cachexia and sarcopenia are of great relevance to cardiologists. In cachexia and sarcopenia a significant number of research publications related to basic science questions of muscle wasting and lipolysis were published between 2010 and 2012. Recently, the two processes of muscle wasting and lipolysis were found to be closely linked. Treatment research in pre-clinical models involves studies on a number of different therapeutic entities, including ghrelin, selective androgen receptor modulators (SARMs), as well as drugs targeting myostatin or melanocortin-4. In the human setting, studies using enobosarm (a SARM) and anamorelin (ghrelin) are in phase III. The last 3 years has seen significant efforts to define the field using consensus statements. In the future, these definitions should also be considered for guidelines and treatment trials in cardiovascular medicine. The current review aims to summarize important information and development in the fields of muscle wasting, sarcopenia and cachexia focussing on findings in cardiovascular research, in order for cardiologists to have a better understanding of the progress in the still not well enough known field.

    To determine the match rate and predictors of matching into an ophthalmology residency. Population-based, cross-sectional study. All 746 candidates who submitted an application for the 2011 ophthalmology residency match. The Ophthalmology Residency Matching Program applicant database was reviewed to determine applicant characteristics and match outcomes. For US seniors, multivariate regression analysis was performed to determine predictors of matching. Match rate and predictors of US seniors matching. Rank lists were submitted by 622 applicants, among whom 458 (74%) matched. The match rate was higher for US seniors (83%) than for independent applicants (41%; P < 0.001). US seniors who matched were more likely to be Alpha Omega Alpha medical honor society members (odds ratio [OR], 2.94; 95% confidence interval [CI], 1.16-7.29), to attend medical schools ranked in the top 40 according to National Institutes of Health funding (OR, 2.25; CI, 1.14-4.43), and to have ranked more programs (OR, 1.44; CI, 1.29-1.60). Those ranking 6 to 10 programs had an 80% to 90% chance of matching, and those ranking more than 10 programs had a greater than 90% chance of matching. No clear benefit was observed by ranking additional programs once 11 had already been ranked. Average US Medical Licensing Examination Step 1 scores were 239 ± 14 and 223 ± 18 for applicants who were matched and unmatched, respectively; this difference was significant by univariate analysis (P < 0.001) but not by multivariate regression (P = 0.163). Ophthalmology ranks among the most competitive specialties in medicine. Those most likely to match were US seniors who maintained academic excellence beginning in their preclinical years. A finite relationship exists between ranking a greater number of programs and having a greater chance of matching. Copyright © 2012 American Academy of Ophthalmology. Published by Elsevier Inc.

    To identify common perceptions and ideas about preparation and planning for retirement of chairs of academic departments of ophthalmology, determining areas of particular stress and proposing ways to better prepare for retirement. Cross-sectional study. One-hundred sixteen chairs of academic departments of ophthalmology in the United States. A confidential online survey emailed to ophthalmology chairs. Surveys assessed demographics; current work schedule; perceptions, preparation, and planning for retirement; and retirement training for faculty and residents. Ninety-six department chairs responded to the survey (82% response rate). Most chairs anticipate retiring around age 70. Significantly, only 9% are looking forward to retirement. Reasons for delaying retirement include keeping active (37%), income/insurance/benefits (20%), and maintaining lifestyle (17%). The most common concern is financing retirement (46%). Forty percent anticipate their reason for retirement will be because of age or health, whereas 20% anticipate fatigue or burnout. Nearly half of the respondents have no specific plan upon retirement. Most respondents anticipate pursuing other interests (43%); 32% intend to spend time with family, vacationing, and travelling. Younger respondents are more concerned with the financial aspects of retirement while more senior respondents appear to delay retirement to keep active or because they enjoy their work. Retirement is a source of stress for many ophthalmology department chairs and many indicate financial preparation is their major concern. Despite this, the major reason for putting off retirement is a desire to keep active. Developing a retirement plan eases stress and engenders a feeling of confidence about the future.

    Avian biology and collection of baseline population data was a major part of the first decade (1951-1961) of field research at the Savannah River Site (SRS). Baseline inventories involving organisms and land-use types were part of the mission in the early contracts between the Atomic Energy Commission (now the Department of Energy) and the University of Georgia prior to the establishment of the Savannah River Ecology Laboratory (SREL) as a National Environmental Research Park Laboratory. About 27% of the SREL publications during this first decade dealt with birds. Since that time, research on the SRS landscape has expanded and broadened with less than 10% of the publications dealing with birds. SRS changed also from an agriculturally dominated area with ca. 40% open areas (fields, crops, pastures) to a timber-managed area with ca. 80% forests, 12% open areas, and 2% open water impoundments. Baseline breeding bird populations of the SRS in the 1950s were typical for the region with avian species richness and density increasing with the age and succession of the vegetation (0-26 species and densities of 0-741 pairs/km2 for the habitats surveyed). During the first decade at the SRS, the resident game bird population of Northern Bobwhites (Colinus virginianus) increased and the Mourning Dove (Zenaida rnacroura) population, a migratory upland game bird, remained stable. Current avian research efforts, as well as new opportunities to reexamine the breeding bird populations and the landscape of SRS, will provide a better understanding of the potential causes of declines of neotropical migratory birds, declines of resident and migratory game birds, and how habitat influences invasions and extinctions of breeding birds in the region. Emphasis for future research and monitoring should be on neotropical migratory bird populations in decline (Yellow-billed Cuckoo, Coccyzus americanus; Eastern Wood-Pewee, Contopus virens; Wood Thrush, Hylocichla mustelina; Prairie Warbler

    Infections associated with the use of intraocular, periocular, or orbital implants are associated with an increase in both morbidity and in the costs of ophthalmological surgery. This is due to an increased number of visits and the need for additional treatments, at a time when some conventional therapies are losing their efficacy, or even hospitalization. To avoid such consequences, the first step should be to prevent the biomaterials that form implants from being colonized by various microorganisms, either intraoperatively or postoperatively. To this end, several lines of research have emerged that aim at equipping implants with antimicrobial properties, some of which are described in this review.

    To evaluate trends in the prevalence of women authors in ophthalmology in recent years. Cohort study. Authors listed in publications of 6 leading ophthalmology journals between January 2002 and December 2014. Using the PubMed search engine, we conducted an observational study of trends in gender distribution of all authors in 6 leading ophthalmology journals between January 2002 and December 2014. In multiauthored articles, the first listed author often is the lead investigator and the last author is the senior author. Therefore, the full names and positions (first, middle, or last) of all authors in every article were collected. A Google-based name identifier was used to assign the gender of authors. Proportion of women authors throughout the study period in all journals, general ophthalmology versus subspecialty journals, and basic science versus clinical research journals. Furthermore, we assessed the proportion of women in different authorship positions (first, middle, and last). A total of 102 254 authors from 23 026 published articles were analyzed. There was a significant rise over time in the percentage of women authors, with a steeper slope for first authors than for last authors (P<0.001), although in 2014, women authors were less than the 50% mark in all categories of authorship. The rise in the percentage of women authors was similar in basic and clinical research, but was steeper for first authorship than for last authorship (P<0.001). In all 3 authorship positions (first, middle, or last), women's contributions consistently were higher in basic research publications. The rise in the percentage of women authors was significantly steeper for general journals than for subspecialty journals (P<0.001). There was no significant rise for last authorship in subspecialty journals. In all 3 authorship positions, the proportion of women was consistently higher in general ophthalmology journals than for subspecialty journals. Despite an overall increase in

    In Denmark, France, Germany, Great Britain and Italy, the OPHTEL project combines clinical centers of ophthalmology and internal medicine, an institute for medical informatics and health services research, a publishing company and different industrial partners in the EDP market. With the aid of visual telecommunication and rapid data transfer, methods and conditions will be developed and proved so that any physician can very easily obtain sufficient information for treating his patient. Thus, the regional differences in the quality of structured health service (e.g., urban/ rural) will be overcome throughout Europe. SCIENTIFIC TASKS: A multilingual diagnostic and therapeutic thesaurus has to be worked out in order to create standards for communication and quality control. Based on literature, images and image analysis in a knowledge-based data bank, a monitoring system (containing watch-dog functions) and the basic aspects of an ophthalmological patient/disease register will be investigated. (In parallel, a technical development of synchronous and asynchronous telecommunication between eye physicians is taking place in close cooperation with the regional Bavarian project Teleopathalmology in Bavaria on-line). State of the art 6 months after starting the project:the knowledge-based image data bank has been founded and also an ophthalmological 8 language thesaurus and definition standard. All data transfer lines are installed. The project is taking place amid diverging sections of medicine: ophthalmology and internal medicine, health politics and data protection, individual treatment and common interest (health care), product management and office organization. Thus, the scientific quality of the transferred ophthalmological content must undergo sophisticated controls. FUTURE STEPS: Intense cooperation with the big German associations for ophthalmology (DOG, BVA) and the European ophthalmological societies concerning EDP, classification and quality control.

    The German Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung, BMBF) has launched a research initiative in 2013/2014 called ROMIC (Role of the Middle Atmosphere in Climate). The aim of ROMIC is to improve our understanding of long term variations in the stratosphere, mesosphere, and lower thermosphere and to investigate their potential role for climate changes in the troposphere. This includes to study coupling mechanisms between various layers and the relative importance of anthropogenic and natural forcing, e. g., by the Sun. Scientists at a total of 15 research institutes in Germany are involved and cover a large range of experimental and theoretical topics relevant for ROMIC. Some scientific highlights from the research projects within ROMIC will be presented.

  20. Simulator Developed to Drastically Reduce Time of Multijunction PV Device Efficiency Measurements (Fact Sheet), NREL Highlights, Research & Development

    NREL's new simulator helps speed up research in the race to improve photovoltaic efficiency. Scientists at the National Renewable Energy Laboratory (NREL) needed a quick and accurate method to predict energy generated from multijunction photovoltaic (PV) test devices. This method had to take into account the nonlinear behavior of multijunction PV. NREL achieved this by developing the One-Sun Multi-Source Simulator (OSMSS), which reduces the time for this type of reference spectrum efficiency measurement from hours or days to minutes. The OSMSS is an automated, spectrally adjustable light source that builds a unique simulator spectrum that causes a multijunction PV device to behave as it would under a reference spectrum. This new simulator consists of four light sources separated into nine wavelength bands between 350 and 2,000 nm. The irradiance in each band is adjustable from zero to about 1.5 suns. All bands are recombined via optical fibers and integrating optics to produce a nearly 10 cm x 10 cm uniform spot. The operator simply links the OSMSS to the quantum efficiency data for the test device, and the OSMSS does the rest. The OSMSS can also determine the power as a function of the spectral irradiance (beyond the reference spectra), total irradiance, and temperature. Major components of the system were built to NREL specification by LabSphere, Inc. NREL developed a new, fully automated tool that rapidly builds a spectrum under which all junctions of a multijunction PV device behave as they would under a reference spectrum. Such a spectrum is essential to properly characterize multijunction devices. The OSMSS reduces the time for building spectra for current vs. voltage measurements from hours or days to minutes. This makes it possible to quickly characterize a multijunction device under many different conditions. The OSMSS will be an important tool to help predict the yearly energy output of a multijunction PV device in a particular environment when provided

    Acid mine drainage (AMD) is presently one of the most important environmental problems in in the densely populated Gauteng Province, South Africa. The threat of acid mine drainage has demanded short-term interventions (some of which are being implemented by government) but more importantly sustainable long-term innovative solutions. There have been moments of public apprehension with some media reports dubbing the current scenario as a future 'nightmare of biblical proportions' and 'South Africa's own Chernobyl' that could cause dissolving of concrete foundations of buildings and reinforcement steel, leading to collapse of structures. In response to the needs of local and provincial authorities, this research was conducted to (1) generate scientific understanding of the effects of AMD on infrastructure materials and structures, and (2) propose innovative long-term remedial systems based on cementitious materials for potential AMD treatment applications of engineering scale. Two AMD solutions from the goldfields and two others from the coalfields were used to conduct corrosion immersion tests on mild steel, stainless steel, mortars, pastes and concretes. Results show that AMD water from the gold mines is more corrosive than that from the coal mines, the corrosion rate of the former being about twice that of the latter. The functionality of metal components of mild steel can be expected to fail within one month of exposure to the mine water. The investigation has also led to development of a pervious concrete filter system of water-cement ratio = 0.27 and cement content = 360 kg/m3, to be used as a permeable reactive barrier for AMD treatment. Early results show that the system was effective in removing heavy metal contaminants with removal levels of 30% SO4, 99% Fe, 50-83% Mn, 85% Ca, and 30% TDS. Further work is on-going to improve and optimise the system prior to field demonstration studies.

    The access to ophthalmological care in Chile has been historically a problem. Only at the end of the twentieth century concrete solutions were promoted. In 1960, Primary Care Ophthalmologic Units were created to ease the access to ophthalmology, due to the efforts of Professor Juan Arentsen. Their functioning was organized and standardized subsequently using a model proposed by the Chilean Ophthalmologic Society, leading to a better patient flow and reducing waiting lists. These units became an innovative initiative to reduce the gaps in Chilean public health, optimizing the professional and infrastructural assets of the public health care system and achieving a new organization for the ophthalmological health care net.

    Intracranial saccular aneurysms are acquired lesions that often present with neuro-ophthalmologic symptoms and signs. Recent advances in neurosurgical techniques, endovascular treatments, and neurocritical care have improved the optimal management of symptomatic unruptured aneurysms, but whether the chosen treatment has an impact on neuro-ophthalmologic outcomes remains debated. A review of the literature focused on neuro-ophthalmic manifestations and treatment of intracranial aneurysms with specific relevance to neuro-ophthalmologic outcomes was conducted using Ovid MEDLINE and EMBASE databases. Cavernous sinus aneurysms were not included in this review. Surgical clipping vs endovascular coiling for aneurysms causing third nerve palsies was compared in 13 retrospective studies representing 447 patients. Complete recovery was achieved in 78% of surgical patients compared with 44% of patients treated with endovascular coiling. However, the complication rate, hospital costs, and days spent in intensive care were reported as higher in surgically treated patients. Retrospective reviews of surgical clipping and endovascular coiling for all ocular motor nerve palsies (third, fourth, or sixth cranial nerves) revealed similar results of complete resolution in 76% and 49%, respectively. Improvement in visual deficits related to aneurysmal compression of the anterior visual pathways was also better among patients treated with clipping than with coiling. The time to treatment from onset of visual symptoms was a predictive factor of visual recovery in several studies. Few reports have specifically assessed the improvement of visual deficits after treatment with flow diverters. Decisions regarding the choice of therapy for intracranial aneurysms causing neuro-ophthalmologic signs ideally should be made at high-volume centers with access to both surgical and endovascular treatments.

    Slovenian ophthalmology developed much at the same time as in the rest of the Central Europe). The first Slovenian ophthalmologist was Dr Ludvik Grbec (1805%emdash;1880). The first Slovenian eye department was established within the Ljubljana civil hospital in 1890, and initially counted 34 hospital beds. Under Dr Emil Bock, the department grew to 120 beds by 1916 and saw a number of surgical procedures performed (mainly cataract operations). Dr Bock also founded a department for the treatment of ocular tuberculosis in children. From 1920 to 1958, the department was resumed by Dr Leopold Ješe, a pioneer of Slovenian ophthalmology, the first professor of ophthalmology at the Ljubljana University Faculty of Medicine (1945), author of the first ophthalmology textbook for students (Ophthalmology, 1946), and the father of Slovenian ophthalmological terminology. This article describes the development of ophthalmology in Slovenian hospitals to this day, especially in the Ljubljana Eye Hospital. It remembers the most prominent figures and professional, educational,and scientific achievements. Now in 2010, Slovenia has over 130 ophthalmologists, two departments teaching ophthalmology (within Ljubljana and Maribor University Faculties of Medicine), an internationally recognised ophthalmology specialisation programme, and influential research work published in various journals indexed by Science Citation Index.

    Western medicine was first introduced to Taiwan by medical missionaries in the mid-19(th) century. Modernization of medicine was systematically transplanted to Taiwan in the Japanese colonial period, and ophthalmology was established third among hospital departments, following internal medicine and surgery. Dr Hidetaka Yamaguchi, an ophthalmologist, was the first head of the Taihoku Hospital, later known as National Taiwan University Hospital (NTUH; Taipei, Taiwan). Ophthalmologists during the colonial period conducted studies on tropical and infectious eye diseases. After World War II, ophthalmologists at NTUH played an important role in medical education, residency training, studies, and teaching. Dr Yan-Fei Yang established the Taiwan Ophthalmological Society in 1960 and instituted its official journal in 1962. Dr Ho-Ming Lin established the Department of Ophthalmology at the Tri-Service General Hospital in the 1950s and the Veterans General Hospital in the 1960s. Taiwan ophthalmologists eradicated trachoma by 1971. Cataract surgery and penetrating keratoplasty were initially performed in the 1960s. Currently, there are about 1600 ophthalmologists in Taiwan conducting an estimated 120,000 cataract surgeries and 600 corneal transplantations annually. Many subspecialty societies have been established recently that serve to educate Taiwanese ophthalmologists and to connect with international ophthalmic societies. Taiwan ophthalmologists continue to contribute to the advancement of ophthalmic knowledge globally. Copyright © 2016. Published by Elsevier B.V.

    Background and Aims: This study documents a survey of final-year ophthalmology postgraduate students on the subject of their residency training. A similar survey conducted 7 years ago published in IJO had concluded that the residency program was not up to expectations in many centers. Our study aimed to see if ophthalmology training and student perceptions differed since then. Materials and Methods: For our study, we added a few questions to the same questionnaire used in the article “which is the best method to learn ophthalmology? Resident doctors’ perspective of ophthalmology training” published in IJO, Vol. 56 (5). Results: Forty-nine students (62.02%) returned completed forms. Most students desired an orientation program on entering residency, and wished to undergo diagnostic training initially. Case-presentation with demonstration and Wet-lab learning were most preferred. There was a big difference between the number of surgeries students actually performed and the number they felt would have been ideal. Conclusion: On the whole, the students still felt the need for improved training across all aspects of ophthalmology. PMID:25116778

    Several plants have been found to have effective against number of ophthalmological problems in Navarra. Information was collected using semi-structured ethnobotanical interviews with 686 informants in 267 locations. In order to confirm the pharmacological application of the uses more cited by the informants, a literature review was conducted. A total of 57 pharmaceutical uses were reported, for 19 plants and 13 families, mainly represented by Asteraceae. The most frequently used parts were inflorescences, flowers, aerial parts, leaves and flowered aerial parts. The related affections fell into eleven categories: bloodshot eyes, watery eyes and wounds, improve vision, irrited eyelids, rheums and styes, tired eyes, conjunctivitis, eyewash, ocular problems in general. The most cited plants were: Chamaemelum nobile (L.) All., Santolina chamaecyparissus L. ssp. squarrosa (DC.) Nyman, Sambucus nigra L. ssp. nigra, Rosa agrestis Savi and Calendula officinalis L. None of them have been pharmacologically validated by Official International Organisms. From the therapeutic point of view, Allium sativum L., Foeniculum vulgare Mill., C. officinalis, and S. chamaecyparissus ssp. squarrosa deserve special attention, because ethnobotanical and pharmacological studies suggest that these medicinal plants are effective for ophthalmological problems. The present study constitutes a good basis for further phytochemical and pharmacological research of these four plants, which could be of interest in the design of new inexpensive, effective and safe drugs. The remaining plants are needed to be screened through standard pharmacological and clinical procedures for their activities. Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.

    Purpose To examine trends in female first and last authors in clinical ophthalmology literature published from January 2000 to December 2009. Methods A total of 3760 articles in American Journal of Ophthalmology (AJO), 2347 articles in Archives of Ophthalmology (Archives), and 3838 articles in Ophthalmology spanning 10 years of published ophthalmology peer-reviewed literature were examined. All original research articles and brief reports indexed online were included. Author gender was determined by an exhaustive Internet search. Articles were excluded if the sex of the author could not be determined or was not applicable (for example, articles by a study group rather than an individual author). Results Gender information was identified in 86.8% of articles for first authors and 86% for last authors. The number of female first authors (P < 0.0001) and last authors (P = 0.005) increased significantly in the study period in all journals examined, with a significant association between the sex of the first and last authors (OR = 2.19; 95% CI, 1.96–2.46; P < 0.0001), when examining all articles. Female representation increased for last authors significantly only in Ophthalmology. There was a significant correlation between gender of the first author and total number of authors that was not observed with last-author sex. Conclusions Female first authorship has increased from 2000 to 2009 and is correlated with the gender of the last author; however, there were fewer female last authors compared to female first authors in the same period.

    To assess and evaluate the current level of ophthalmology knowledge and teaching curriculum in undergraduate year 3 (MS-3) at Western University. The Undergraduate Medical Education Curriculum at Western University has instituted additional ophthalmology lecture series to all MS-3 students. A test on basic ophthalmic knowledge was administered to MS-3 students immediately before and after lecture series to evaluate the level of knowledge at baseline and after ophthalmology didactic teaching. An evaluation survey was also given to MS-3 students to assess students' self-perceived level of competency, exposure, and interests in ophthalmology. A total of 134 students attended the ophthalmology lecture series in the study, and 88.1% of students completed the pretest, post-test, and Ophthalmology Education Survey. The average pretest and post-test scores were 40.7% and 75.6% (p < 0.01), respectively. The average rating from MS-3 students for ophthalmology exposure during medical school education was 2.11 (1 = "very minimal" and 5 = "more than adequate"). The average rating for desire for additional didactic ophthalmology lectures was 4.02 (1 = "strongly disagree" and 5 = "strongly agree"). The average rating for interest in ophthalmology was 2.74 (1 = "very little interest" and 5 = "very strong interest"). The additional ophthalmology lecture series had a positive impact on the level of ophthalmic knowledge among MS-3 students, and a strong desire for more ophthalmology teaching during medical school education was identified, as evidenced by the survey undertaken by students after the lectures.

  16. Review: Magnetic resonance imaging techniques in ophthalmology

    PubMed Central

    Fagan, Andrew J.

    2012-01-01

    Imaging the eye with magnetic resonance imaging (MRI) has proved difficult due to the eye’s propensity to move involuntarily over typical imaging timescales, obscuring the fine structure in the eye due to the resulting motion artifacts. However, advances in MRI technology help to mitigate such drawbacks, enabling the acquisition of high spatiotemporal resolution images with a variety of contrast mechanisms. This review aims to classify the MRI techniques used to date in clinical and preclinical ophthalmologic studies, describing the qualitative and quantitative information that may be extracted and how this may inform on ocular pathophysiology.

    In 1999, the Department of Medicinal Chemistry and Pharmacognosy at the College of Pharmacy, University of Illinois (UIC) at Chicago was funded to establish a Botanical Dietary Supplements Research Center from the National Institutes of Health (NIH). The emphasis of the UIC/NIH Center for Botanical Dietary Supplements Research (CBDSR) is botanical dietary supplements (BDS) for women's health. Center’s research has focused on BDS that may improve women's health and quality of life, specifically in the areas of menopause, premenstrual syndrome, and persistent urinary tract infections. Center investigators have overcome many challenges associated with botanical dietary supplements research, including acquiring and identifying plant species for investigation, isolating and identifying active constituents, elucidating the mechanisms of action of these botanicals, and conducting phase I and phase II clinical studies. Black cohosh [Actaea racemosa L. (Ranunculaceae)] has been used as a model to illustrate the steps involved in taking a botanical dietary supplement from the field, all the way to clinical trials. Bioassays are described that were necessary to elucidate the pertinent biological studies of plant extracts and their mechanisms of action. The Center has used an innovative multidisciplinary approach to this type of research, and thus has been very successful in fulfilling its specific aims. PMID:20161501

    Aims Cognitive factors (eg, academic achievement) have had a significant role in selecting postgraduate surgical trainees in the past. This project sought to determine the role of a national undergraduate ophthalmology prize examination (Duke–Elder examination) in the selection of postgraduate ophthalmology trainees. This would also serve as a quality assurance exercise for the assessment, in which the ultimate aim is to encourage trainees into ophthalmology. Methods A retrospective analysis of the top 20 ranked candidates in the Duke–Elder examination from 1989 to 2005 (except 1995) was carried out to determine which of them subsequently entered the ophthalmic training and General Medical Council Specialist Registers. Results Out of the top 20 candidates in the exam, 29.5% went into specialist training in ophthalmology. Some appeared in the top 20 more than once, with 56% of them going into ophthalmic training, but they had a similar median time to enter training as those who appeared in the top 20 once. There was no significant evidence to suggest that the overall median ranking scores between the UK medical schools differed (P=0.23; Kruskal–Wallis test). However, there was a marked difference in frequency of top 20 candidates from each medical school, which could not be explained by the size of the medical school alone. Conclusion It is difficult to conclude from these findings the importance that the Duke–Elder examination has in the selection of trainees into ophthalmology. The role of cognitive factors in selection into postgraduate medical/surgical training is discussed, along with the potential academic criteria, which may influence interview scores. PMID:21587276

    The aim of the study was to investigate the prevalence and the incidence of ocular complications in contact sport disciplines in a large population of professional and amateur athletes over a period of 3 years. We performed a retrospective review of 694 medical records from athletes examinated from 2008 to 2011. The following data were collected during the routine visit for agonistic sports eligibility: medical history, age, weight, years of sport practice, approximate number of matches, head and eyes injuries during and beyond of the match and a through ocular history. All athletes underwent a detailed ophthalmological evaluation. The follow-up of each athlete was carried out during the following routine visit for agonistic sports eligibility. Most common disorders observed were: peripheral retinal degeneration, blepharitis, conjunctival and corneal diseases with a prevalence of 7%, 4%, 7% and 4% respectively. It was observed a positive correlation between peripheral retinal degeneration and age in amateur male boxers. Moreover, we noticed an incidence of 6% of laser therapeutic treatments as a result of retinal holes or degenerations, during the follow-up. Contact sport disciplines did not result in higher prevalence of severe ocular lesion. Both conjuntival diseases and peripheral retinal degenerations represented the ophthalmologic disorders with the higher prevalence in our sample. In particular, peripheral retinal degeneration is remarkable because of the increased risk of retinal detachment. Dyschromatopsie, even if quite rare, should be considered when analysing the reception of shots, since gloves in most cases are either red or blue.

    Objective: To report the clinical presentation of malarial retinopathy in an adult, emphasizing the importance of this diagnosis for the clinical suspicion and prognosis of cerebral malaria. Methods: A 39-year-old caucasian man presented with hemolytic anemia, thrombocytopenia, acidemia and acute renal failure, developing severe encephalopathy. The diagnosis of Plasmodium falciparum malaria was done and after systemic stabilization, the patient noticed a central scotoma in the left eye. Ophthalmological examination revealed retinal features of malarial retinopathy. Results: At one-month follow-up, the patient had improved his systemic condition and the left eye scotoma had disappeared. Visual acuity was 20/20 in both eyes and on examination almost all lesions had regressed. Conclusion: Malarial retinopathy is a diagnostic factor and a prognosis indicator of severe P. falciparum infection, usually with brain involvement. The knowledge of the ophthalmological features associated with severe malaria, which is more frequent in children but can also occur in adults, becomes imperative in order to reduce the risk of neurologic sequelae and associated mortality.

  6. [Johannes Kepler's contributions to ophthalmologic optics].

    PubMed

    Jaeger, W

    1986-02-01

    Until the beginning of the 17th century it was held that an image is formed in the eye on the anterior surface of the crystalline lens. Ophthalmological optics as a scientific discipline only began with a discovery made by Johannes Kepler. Without performing new experiments, and solely by application of the laws of light refraction, he analyzed the path of light through the eye and demonstrated that an image is formed on the retina and that it is inverted. Acceptance of this discovery was impeded by contemporary prejudices which could imagine nothing but an upright image in the eye, even though this attitude could not explain certain phenomena. Kepler's discovery of the path of light in the eye made it possible to explain the following physical phenomena: central visual acuity, visual field, dark adaptation, and errors of refraction. Physiological diplopia and the mechanism of accommodation were discovered later. The law stating that the intensity of light decreases with the square of distance was also formulated by Johannes Kepler; this law, too, could only be demonstrated after the path of light through the eye had been discovered. In recent years the Keplerian telescope has assumed a practical significance in ophthalmological optics. As a reading aid for individuals with impaired vision it offers a significantly higher magnification than any other optical visual aid.

Ophthalmological examination revealed retinal features of malarial retinopathy. At one-month follow-up, the patient had improved his systemic condition and the left eye scotoma had disappeared. Visual acuity was 20/20 in both eyes and on examination almost all lesions had regressed. Malarial retinopathy is a diagnostic factor and a prognosis indicator of severe P. falciparum infection, usually with brain involvement. The knowledge of the ophthalmological features associated with severe malaria, which is more frequent in children but can also occur in adults, becomes imperative in order to reduce the risk of neurologic sequelae and associated mortality.

    Atomic force microscopy (AFM) allows to examine surface of different biological objects in the nearly physiological conditions at the nanoscale. The purpose of this work is to present the history of introduction and the potential applications of the AFM in ophthalmology research and clinical practice. In 1986 Binnig built the AFM as a next generation of the scanning tunnelling microscope (STM). The functional principle of AFM is based on the measurement of the forces between atoms on the sample surface and the probe. As a result, the three-dimensional image of the surface with the resolution on the order of nanometres can be obtained. Yamamoto used as the first the AFM on a wide scale in ophthalmology. The first investigations used the AFM method to study structure of collagen fibres of the cornea and of the sclera. Our research involves the analysis of artificial intraocular lenses (IOLs). According to earlier investigations, e.g. Lombardo et al., the AFM was used to study only native IOLs. Contrary to the earlier investigations, we focused our measurements on lenses explanted from human eyes. The surface of such lenses is exposed to the influence of the intraocular aqueous environment, and to the related impacts of biochemical processes. We hereby present the preliminary results of our work in the form of AFM images depicting IOL surface at the nanoscale. The images allowed us to observe early stages of the dye deposit formation as well as local calcinosis. We believe that AFM is a very promising tool for studying the structure of IOL surface and that further observations will make it possible to explain the pathomechanism of artificial intraocular lens opacity formation.

    We screened 46 ophthalmology journals to identify the most frequently cited articles using the Science Citation Index Expanded (1975 to 2006). The 100 most-cited articles were published in 13 journals, most in the Archives of Ophthalmology (n = 30), followed by Ophthalmology (n = 27) and the American Journal of Ophthalmology (n = 11), and originated from 10 countries, led by the United States (n = 86). The topics covered by these classic articles included epidemiology of age-related macular degeneration and glaucoma, description of new diseases including cytomegalovirus retinitis, optical coherence tomography, hypotensive medications in glaucoma, laser photocoagulation to treat diabetic retinopathy and subfoveal choroidal neovascularization, photorefractive surgery, and vitrectomy to treat idiopathic macular hole. The most frequently cited articles provide a historical perspective in the scientific advancement of ophthalmology during the last 3 decades.

  14. Satellite clinics in academic ophthalmology programs: an exploratory study of successes and challenges.

    PubMed

    Kuo, Irene C

    2013-12-14

    Major academic ophthalmology departments have been expanding by opening multi-office locations ("satellites"). This paper offers a first glimpse into satellites of academic ophthalmology departments. Leaders of seven medium to large, geographically diverse departments agreed to participate. One- to two-hour phone interviews were conducted to assess the features of their satellite practices. Success as clinical entities, profitability, and access to patients were stated goals for most satellites. In approximate descending order, refractive surgery, retina, oculoplastics, and pediatric ophthalmology were the most common subspecialties offered. Faculty staffing ranged from recruitment specifically for satellites to rotation of existing faculty. Except for a department with only one academic track, satellite doctors were a mix of tenure and mostly non-tenure track faculty. According to these department leaders, scholarly productivity of satellite faculty was similar to that of colleagues at the main campus, though research was more community-based and clinical in nature. Fellowship but little resident education occurred at satellites. Though it was agreed that satellite practices were integral to department finances, they accounted for a smaller percentage of revenues than of total departmental visits. Satellite offices have offered access to a better payor mix and have boosted the finances of academic ophthalmology departments. Challenges include maintaining collegiality with referring community physicians, integrating faculty despite geographic distance, preserving the department's academic "brand name," and ensuring consistent standards and operating procedures. Satellite clinics will likely help departments meet some of the challenges of health care reform.

  15. "Eyes" on the thrones: imperial ophthalmologic nicknames.

    PubMed

    Lascaratos, J

    1999-01-01

    Several Greek and Byzantine sovereigns are known in history by nicknames that are of ophthalmologic origin; the sobriquets derive from characteristics of their eyes or their actions in relation to the eyes. The first was Antigonos I Monophthalmus (the One-eyed), who was the most eminent successor of Alexander the Great and Sovereign of Eastern Mediterranean Asia. He obtained his nickname at an early age when he lost one eye fighting at the seige of Perinthos, as a general of King Philip of Macedon (father of Alexander the Great). Several Byzantine emperors also have a number of similar nicknames, such as Anastasius I Dicoros (with Heterochromia Iridis), Alexius V Ducas Murtzuphlus (with Scowling Eyebrows), and Andronicus I Comnenus Misophaes (Hater of Sunlight, since he blinded a great number of his opponents). To these must be added the Byzantine Empress Zoe Carvounopsina (with Coal-black Eyes).

    This short paper mentioned the medical treatment using the 'holy' springs, the first 'eye doctor' in Denmark, the first picture of spectacles which was found in Viborg Cathedral of the high priest before he performs circumcisio praeputii on Jesus Christ, further cataract reclination in Denmark from around year zero and cataract extraction in 1667 in Denmark on a goose by Francisco Borri and on humans by the Danish Georg Heuermann in 1755. Epidemic military eye diseases in 1807, 1856 and 1865 are also described in this study. From 1856, a new ophthalmological period started in Denmark with the first eye hospital (lazaret only for eye diseases), and in 1864, patients with eye diseases were transported from the few beds in the surgical departments in the municipal hospital to the first civil eye department in Denmark, the eye hospital Sct. Annae in Copenhagen. The new scientific period started with Jacob Christian Bentz (ophthalmia granulosa, joint editor of the Danish Medical Journal) and Heinrich Lehmann.

    Genetic disease affecting vision can significantly impact patient quality of life. Gene therapy seeks to slow the progression of these diseases by treating the underlying etiology at the level of the genome. Clustered regularly interspaced short palindromic repeats (CRISPR) and CRISPR-associated systems (Cas) represent powerful tools for studying diseases through the creation of model organisms generated by targeted modification and by the correction of disease mutations for therapeutic purposes. CRISPR-Cas systems have been applied successfully to the visual sciences and study of ophthalmic disease – from the modification of zebrafish and mammalian models of eye development and disease, to the correction of pathogenic mutations in patient-derived stem cells. Recent advances in CRISPR-Cas delivery and optimization boast improved functionality that continues to enhance genome-engineering applications in the eye. This review provides a synopsis of the recent implementations of CRISPR-Cas tools in the field of ophthalmology. PMID:28573077

    Optical aberrations reduce the imaging quality of the human eye. In addition to degrading vision, this limits our ability to illuminate small points of the retina for therapeutic, surgical or diagnostic purposes. When viewing the rear of the eye, aberrations cause structures in the fundus to appear blurred, limiting the resolution of ophthalmoscopes (diagnostic instruments used to image the eye). Adaptive optics, such as deformable mirrors may be used to compensate for aberrations, allowing the eye to work as a diffraction-limited optical element. Unfortunately, this type of correction has not been widely available for ophthalmic applications because of the expense and technical limitations of current deformable mirrors. We present preliminary design and characterisation of a deformable mirror suitable for ophthalmology. In this ferrofluidic mirror, wavefronts are reflected from a fluid whose surface shape is controlled by a magnetic field. Challenges in design are outlined, as are advantages over traditional deformable mirrors.

    Discoveries of some ancient medical instruments and equipment found in the Hellenic world have been published in magazines of general interest and in a rare Greek medical journal, yet none caught the attention of ophthalmologists. Among these instruments are two forms of the famous 'Kenteterion', dating from the Hellenistic period, used for the couching of cataract. These were found on the island of Milos in the last century. Two magnifying lenses of the Archaic period from the recent Cretan excavations gave us the opportunity to discuss the problem of their medical use. The two drop-bottles from the excavations on Cyprus and at Tanagra, which are also described, seem to be of medical, and possible ophthalmological, use.

    Patients with spina bifida have multiple ophthalmologic problems, many of which are preventable. Most of the problems are related to the hydrocephalus, which is caused by the coexisting Arnold-Chiari malformation. When patients are treated for hydrocephalus, and comprehensive eye care is available, 94% of the patients will have 6/12 visual acuity or better. Strabismus is common but it responds well to medical and surgical treatment. Children with spina bifida should have frequent examinations by an ophthalmologist who is familiar with the diagnosis and management of the defects recorded in this study.

  1. Femtosecond Lasers in Ophthalmology: Surgery and Imaging

    NASA Astrophysics Data System (ADS)

    Bille, J. F.

    Ophthalmology has traditionally been the field with prevalent laser applications in medicine. The human eye is one of the most accessible human organs and its transparency for visible and near-infrared light allows optical techniques for diagnosis and treatment of almost any ocular structure. Laser vision correction (LVC) was introduced in the late 1980s. Today, the procedural ease, success rate, and lack of disturbing side-effects in laser assisted in-situ keratomileusis (LASIK) have made it the most frequently performed refractive surgical procedure (keratomileusis(greek): cornea-flap-cutting). Recently, it has been demonstrated that specific aspects of LVC can take advantage of unique light-matter interaction processes that occur with femtosecond laser pulses.

    To study the ophthalmological manifestations in individuals with the typical features of neurofibromatosis type 1 (NF1) circumscribed to one or more body segments, usually referred to as segmental NF1. Visual acuity and colour tests, visual field examination, slit lamp biomicroscopy of the anterior segment, and a detailed examination of the retina by indirect ophthalmoscopy were performed at diagnosis and follow up in 72 consecutive subjects (29 males, 43 females; aged 1-64 years; mean age 14.6 years) seen at the university departments of paediatrics in Catania and Rome, Italy, during years 1990-2003, who had in restricted body areas: (1) typical pigmentary manifestations of NF1 (cafe au lait spots and freckling) only (n = 48); (2) NF1 pigmentary manifestations and neurofibromas alone (n = 2); (3) neurofibromas only (n = 15); and (4) plexiform neurofibromas only (n = 7). None of the 72 patients had Lisch nodules in the iris irrespective of age at eye examination or hypertelorism (a "minor" NF1 feature) and none developed typical associated ophthalmological NF1 complications. An additional child had an isolated optic pathways glioma (OPG), which behaved both biologically and radiographically as an NF1 associated OPG. This represents the first systematic study reporting on eye involvement in the largest series of individuals at different ages having segmental NF1. As one of the postulated mechanisms to explain segmental NF1 is somatic mosaicism for the NF1 gene (so far demonstrated only in two patients) the present findings could be explained either by the fact that the eye is too far from the mutated area with NF1 lesions in most cases or by the NF1 (or other "predisposing" or "cooperating") gene mutation restricted to too few cellular clones or to tissues embryologically different from the eye.

    Visual acuity is the primary measure used in ophthalmology to determine how well a patient can see. Visual acuity for a single eye may be recorded in multiple ways for a single patient visit (eg, Snellen vs. Jäger units vs. font print size), and be recorded for either distance or near vision. Capturing the best documented visual acuity (BDVA) of each eye in an individual patient visit is an important step for making electronic ophthalmology clinical notes useful in research. Currently, there is limited methodology for capturing BDVA in an efficient and accurate manner from electronic health record (EHR) notes. We developed an algorithm to detect BDVA for right and left eyes from defined fields within electronic ophthalmology clinical notes. We designed an algorithm to detect the BDVA from defined fields within 295,218 ophthalmology clinical notes with visual acuity data present. About 5668 unique responses were identified and an algorithm was developed to map all of the unique responses to a structured list of Snellen visual acuities. Visual acuity was captured from a total of 295,218 ophthalmology clinical notes during the study dates. The algorithm identified all visual acuities in the defined visual acuity section for each eye and returned a single BDVA for each eye. A clinician chart review of 100 random patient notes showed a 99% accuracy detecting BDVA from these records and 1% observed error. Our algorithm successfully captures best documented Snellen distance visual acuity from ophthalmology clinical notes and transforms a variety of inputs into a structured Snellen equivalent list. Our work, to the best of our knowledge, represents the first attempt at capturing visual acuity accurately from large numbers of electronic ophthalmology notes. Use of this algorithm can benefit research groups interested in assessing visual acuity for patient centered outcome. All codes used for this study are currently available, and will be made available online at https://phekb.org.

    To develop a help-wanted index (HWI) to measure trends in marketplace demand for ophthalmologists, to identify the economic drivers of demand, and to determine the impact of economic recessions on the ophthalmology job market. Review of physician recruitment advertisements appearing in the journals Ophthalmology, American Journal of Ophthalmology, and Archives of Ophthalmology from January 1980 through June 2006. Over the 26-year study period a consistent increase in the demand for subspecialists (31% of HWI in 1980 to 80% in 2005) was noted. There was also an increase in the demand for academic ophthalmologists. The need for academic ophthalmologists seems to be correlated with national research expenditure and stock market gains (P = .00191), whereas demand for private practice ophthalmologists seems to be correlated with the national economic well-being, as measured by gross domestic product (GDP) (P < .001). Residency applicants (P = .0128) and fellowship applicants (P = .0198) respond to marketplace demand. During the recessions, the demand for ophthalmologists fell 2 to 3 years after the economic downturn. Over a 26-year period, HWI data suggest an increased need for subspecialists and academic ophthalmologists. The ophthalmic community has been quick to respond to marketplace demand. National research expenditure, stock market gains, GDP, and discretionary health care expenditure have been associated with the ophthalmology job market. These factors tend to decline with economic recessions. Historically, the demand for ophthalmologists has declined 2 to 3 years following a recession, which may mean lower demand in the near future, given the recent recession.

    1993-01-01

    Meteorological highlights from the third NASA Global Tropospheric Experiment Chemical Instrumentation Test and Evaluation (GTE/CITE 3) are presented. During August and September 1989, research flights were conducted from Wallops Island, Virginia, and Natal, Brazil, and included airborne sampling of air masses over adjacent regions of the Atlantic Ocean. Isentropic backward trajectory calculations, wind vector/streamline fields, rawinsonde data, and GOES and METEOSAT satellite imagery are utilized to examine the meteorological conditions for each flight and to determine the transport paths of the sampled air masses. Some aspects of the chemical signatures of the sampled air are also discussed. During the series of flights based at Wallops Island, Virginia, the flow into the experiment area was governed primarily by the position of the North Atlantic subtropical anticyclone. The large-scale tropospheric circulation switched from primarily a marine flow during flights 1-4, to a predominantly offshore mid-latitude continental flow during flights 5-10. During these later flights, the regional influences of large eastern U.S. cities along with vertical mixing by typical summertime convective activity strongly influenced the chemical characteristics of the sampled air. During the series of flights based at Natal, Brazil, the dominant synoptic feature was the South Atlantic subtropical anticyclone which generally transported air across the tropical Atlantic toward eastern Brazil. Pronounced subsidence and a well-defined trade wind inversion often characterized the lower and middle troposphere over the Natal region. Some high-altitude recirculation of air from South America was observed, as was cross-equatorial transport which had come from northern Africa. Biomass burning plumes were observed on segments of all of the flights, the source region being the central and southern savannah regions of Africa.

    The NonParametric Combination methodology (NPC) of dependent permutation tests allows the experimenter to face many complex multivariate testing problems and represents a convincing and powerful alternative to standard parametric methods. The main advantage of this approach lies in its flexibility in handling any type of variable (categorical and quantitative, with or without missing values) while at the same time taking dependencies among those variables into account without the need of modelling them. NPC methodology enables to deal with repeated measures, paired data, restricted alternative hypotheses, missing data (completely at random or not), high-dimensional and small sample size data. Hence, NPC methodology can offer a significant contribution to successful research in biomedical studies with several endpoints, since it provides reasonably efficient solutions and clear interpretations of inferential results.

Permutation tests for complex data: theory, applications and software. Chichester, UK: John Wiley &Sons, 2010. We focus on non-parametric permutation solutions to two real-case studies in ophthalmology, concerning complex-repeated measures problems. For each data set, different analyses are presented, thus highlighting characteristic aspects of the data structure itself. Our goal is to present different solutions to multivariate complex case studies, guiding researchers/readers to choose, from various possible interpretations of a problem, the one that has the highest flexibility and statistical power under a set of less stringent assumptions. MATLAB code has been implemented to carry out the analyses.

    One of the most complete and permanent ways of treating many causes of visual impairment and blindness is to replace the entire affected tissue with pre-cultured ocular tissues supported and maintained on biomaterial frameworks. One direction towards enhancing ocular tissue regeneration on biomaterials, in the laboratory is by applying biomimicry. Specifically to engineer biomaterials with important functional elements of the native extracellular matrices, such as topography, that support and organise cells into coherent tissues. Further problems in regenerative ophthalmology can be potentially solved through application of biomimicry. They include, more efficient ways of moving and transplanting cultivated tissues into correct therapeutic locations inside the eye and scar-less, non-destructive healing of surgical incisions and wounds, to repair structural integrity of tissues at the ocular surface. Two examples are given to show this potential for redeveloping an ocular epithelium onto a nanostructured insect wing surface and producing an origami membrane modelled on deployable structures in nature. Efforts to harness natural innovation will eventually provide unique designs and structures that cannot for now be made synthetically, for regeneration of clinically acceptable ocular tissues.

  15. Lasers in ophthalmology: achievements and new directions

    The main characteristics of the laser radiations are: directivity, monochromaticity and spatially and temporally coherence. Using the aggregation state as a criterion for classification, we describe solid, liquid and gaseous active media. Concerning the methods used to realize the population inversion, we also describe: optically, electrically and high energy particles pumped lasers. Depending on the laser media and the mode of excitation, a laser may operate in multiple ways: the continuous-wave operation, the long-pulsed operation, the Q-switched mode of operation and the mode-locked operation. The interaction of laser radiations with the living matter is based upon four main effects: the thermal, mechanical, electrical and biological effect. The main field of therapeutical use of lasers are: the management of lid tumors and intraocular tumors, dacryocystorhinostomy, the treatment of diabetic retinopathy, thromboembolic retinal syndromes, inflammatory choriretinal disease, chorioroetinal degenerations, retinal angimatosis, retinal breaks and retinal detachment, corneal diseases, glaucoma, lens diseases. Laser has also nontherapeutical applications in diagnosis and prognosis of ophthalmologic diseases.

  16. Ultrasonic biomicroscopy in ophthalmology and eye banking

    1999-06-01

    Echography has become a valuable diagnostic tool in ophthalmology. Ultrasonic biomicroscopy (UBM) in particular may be applied to the evaluation of small lesions of the anterior segment of the eye. Disease processes such as conjunctival and iris melanoma, other forms of neoplasia, intraocular cysts, narrow angle glaucoma, and intraocular foreign bodies can be diagnostically evaluated and followed longitudinally by UBM. Combining UBM with spectroscopy may become useful in determining cell type origins of a variety of tumors. Eye banking also has an increased need for UBM in corneal tissue banking. The recent development of the Laser In Situ Keratomileusis procedure has allowed corneal surgeries to create a partial thickness flap of tissue in the cornea, remove tissue from the base of the cornea with excimer laser ablation, and replace the hinged flap. This causes a substantial change in refractive error while thinning the cornea and leaving an interface within the corneal stroma. The ability to detect this type of surgery is essential in eye banking. Ultrasonic pachymetry to determine central thickness and biomicroscopy to detect the presence of an interface are essential in avoiding the use of these corneas for transplantation purposes. Determining the topography of the preserved corneas is another potential application for ultrasonography. Using this information to reduce optical aberration after transplant is crucial in improving visual performance post transplantation. A review of the anatomy of the eye, pathology of ocular diseases relevant to UBM, and principles of eye banking will be presented.

    Objective: To evaluate the nature and incidence of pathological ocular conditions in boxing. Methods: A group of 20 active, elite, amateur, asymptomatic Turkish boxers were examined and compared with a control group composed of 20 age matched sportsmen who were not boxers. The boxers had been actively boxing for 5–20 years (mean 9.65), were aged 16–34 (mean 22.25), and weighed 51–91 kg (mean 73.07). They had been involved in 67–500 fights (mean 143.8), with 5–40 losses (mean 17.75). All were championship title holders at the national, European, Olympic, or World level. Results: An atrophic retinal hole was found in one boxer, which was treated with laser prophylaxis. In this series, the incidence of traumatic eye injuries was much lower than in the literature. Possible reasons are their young age, their division being mainly lightweight or middleweight, few fight losses, being elite boxers, their fighting distance being near or distant, protective methods, and racial factors. Conclusion: Boxing does not appear to be as hazardous to the eyes as previously reported, but prospective, longitudinal studies need to be carried out, including boxers of all divisions, ages, boxing experience, and level, and using various methods of fighting and protection. It should be made mandatory for all boxers to have a complete ophthalmological examination at the beginning of their careers and periodically thereafter. PMID:12453836

    We present images of ocular tissues obtained using ultrahigh resolution full-field OCT. The experimental setup is based on the Linnik interferometer, illuminated by a tungsten halogen lamp. En face tomographic images are obtained in real-time without scanning by computing the difference of two phase-opposed interferometric images recorded by a high-resolution CCD camera. A spatial resolution of 0.7 μm × 0.9 μm (axial × transverse) is achieved thanks to the short source coherence length and the use of high numerical aperture microscope objectives. A detection sensitivity of 90 dB is obtained by means of image averaging and pixel binning. Whole unfixed eyes and unstained tissue samples (cornea, lens, retina, choroid and sclera) of ex vivo rat, mouse, rabbit and porcine ocular tissues were examined. The unprecedented resolution of our instrument allows cellular-level resolution in the cornea and retina, and visualization of individual fibers in the lens. Transcorneal lens imaging was possible in all animals, and in albino animals, transscleral retinal imaging was achieved. We also introduce our rapid acquisition full-field optical coherence tomography system designed to accommodate in vivo ophthalmologic imaging. The variations on the original system technology include the introduction of a xenon arc lamp as source, and rapid image acquisition performed by a high-speed CMOS camera, reducing acquisition time to 5 ms per frame.

    Most ophthalmologic disorders secondary to hypercoagulabe state are due to the confluence of congenital and adquired factors. A systematic workup is mandatory. Most of congenital coagulation disorders cause venous trombosis and are inherited autosomal dominantly. In order of frequency these are factor V Leiden mutation (activated protein C resistance), G20210A mutation of the prothrombin gen and protein C, protein S, and antithrombin III deficiencies. Sickle cell anemia can determine arerial and venous thrombosis. In relation with arterial occlusion, the markers most frequently involved are homcysteine fasting levels and the markers of antiphospholipid antibody syndrome. Both of them can also determine venous thrombosis. Several acquired factors can lead to hypoercoagulable state, especially hyperhomocysteinemia, antiphospholipid antibody syndrome, hepatic disease, alcohol and tobacco intake, oral contraceptives, immobilization, surgeries and malignancies. In central venous occlusion is only necessary to rule out hyperhomocysteinemia and antiphospholipid antibody syndrome in young patients without known risk factors. In central artery occlusion, hypercoagulable workup is only recommended for patients less than 50 years-old with unknown emboli source. In this cases protein C, protein S, and antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome will ruled out. In non arteritic ischemic optic neuropathy hypercoagulable work up is not necessary. In amaurosis fugax without known emboli source, it is recommended to rule out etiologies of arterial occlusion, especially antithrombin III deficiencies, homocystein, sickle cell disease and antiphospholipid antibody syndrome.

  20. Use of Botulinum Neurotoxin in Ophthalmology

    2016-01-01

    Botulinum neurotoxin (BoNT) is the first biological toxin used in the treatment of ophthalmic diseases and to decrease skin wrinkles as an aesthetic agent. When used appropriately, it weakens the force of muscular contraction and/or inhibits glandular secretion. The most common areas for botulinum toxin treatment are the upper face, including the glabella, forehead, brows, and lateral canthal lines, or crow’s feet. By relaxing the muscles causing wrinkles, non-permanent results may be achieved with its use. BoNT has gained widespread use in a variety of ophthalmic diseases. The effect of BoNT is temporary, but the therapeutic benefit is usually maintained even after repeated injections. Treatment is usually well tolerated. Complications and side effects associated with the treatment are rare and temporary. Complications occur due to weakness (chemodenervation) of adjacent muscle groups, immunological mechanisms and injection technique. Current therapeutic indications, doses, complications and contraindications of BoNT use in the following disorders related to ophthalmology were investigated: aesthetic use, strabismus, blepharospasm, hemifacial spasm, eyelid retraction, entropion, lacrimal hypersecretion syndrome, and facial paralysis.

  1. [Do We Still Need Electrophysiology in Ophthalmology?

    PubMed

    Tegetmeyer, H

    2016-12-01

    Electrophysiological methods in clinical ophthalmology include the full-field electroretinogram (ERG) for assessment of outer and middle retinal layers, pattern ERG (PERG) for assessment of ganglion cell function, the electrooculogram (EOG) for assessment of retinal pigment epithelium function, as well as visual evoked potentials (VEP) for assessment of the visual pathway, including the optic nerve and visual cortex. Multifocal recording techniques for ERG and VEP are used for tests within selected areas of the visual field. Technical progress in ocular imaging, especially optical coherence tomography (OCT) and fundus autofluorescence (FAF), allows high-resolution imaging of subtle morphological changes of the retina and posterior fundus. Typical retinal diseases may then be diagnosed at an early stage, without conventional electrophysiological investigations (e.g. x-linked retinoschisis, Stargardt disease, vitelliform macular dystrophy). OCT outclasses electrophysiological methods in the quantification of optic atrophies. With newly developed optic techniques, peripheral retinal structures (wide angle optics) and subtle structures up to the photoreceptor level (adaptive optics) can be imaged with increasing quality. However, differentiation of central retinal disorders (e.g. macular dystrophy) from generalised retinal diseases requires electrophysiological diagnostic testing. The same applies to discrimination between different functional disorders in generalised retinal diseases (e.g. enhanced S-cone syndrome, congenital stationary night blindness, achromatopsia).

    Antonio Scarpa (1752-1832) was a prominent scholar who contributed greatly to otolaryngology, orthopedics, ophthalmology, neuroanatomy, and surgery. In 1801, he published a textbook on ophthalmology, the first Italian textbook on this subject and the most propagated European ophthalmic textbook in the first half of the 19th century. The book included important descriptions of lacrimal system disorders, many oculoplastic procedures, and the first description of posterior staphyloma.

    To evaluate the trends in subspecialty fellowship training by Canadian ophthalmology graduates over the last 25 years. Cross-sectional study. Canadian-funded, Royal College-certified graduates from 1990 to 2014 who completed a full residency in an English-language Canadian ophthalmology postgraduate training program. Data were obtained by contacting all 11 English-language ophthalmology residency programs across Canada for demographic and fellowship information regarding their graduates. Society web sites were then used to corroborate and complement the data set, including those of the Canadian Ophthalmology Society, American Academy of Ophthalmology, and Provincial Colleges of Physicians and Surgeons. Data were organized by demographic variables, and analysis was performed using SPSS v22.0. Of the 528 graduates from 1990 to 2014, 63.5% pursued fellowship training. Males and females were equally likely to undertake fellowship training. The proportion of graduates obtaining fellowship training did not change significantly during this 25-year period. The most popular subspecialty choices were vitreoretinal surgery (24.5%), glaucoma (16.7%), and anterior segment (16.7%). Significantly more males than females pursued vitreoretinal surgery and oculoplastics fellowships (p = 0.001, χ(2) test), whereas females were more likely to train in a paediatric ophthalmology and strabismus fellowship (p = 0.001, χ(2) test). The majority of ophthalmology graduates from English-language residency programs pursue subspecialty fellowship training. An understanding of trends in fellowship training may be helpful for both workforce planning and career decision making. Copyright © 2016 Canadian Ophthalmological Society. Published by Elsevier Inc.

  5. The American Journal of Ophthalmology 1862-1864.

    PubMed

    Newell, F W

    1997-01-01

    The American Journal of Ophthalmology was the first specialty periodical to be published in the Western hemisphere; the first issue appeared in New York City July 1862. Its editor and publisher was Julius Homberger, M.D., aged 22 years, who had emmigrated from Germany in January 1861. Six issues were published the first year and The Journal ceased publication after two issues in 1864. Possibly, the American Ophthalmological Society, the first national medical specialty society, was founded in 1864 in a reaction to Homberger, his journal, and his strong belief that specialists, but not other practitioners, should be permitted to advertise their skills. In 1866, Homberger submitted his resignation to the American Medical Association, which he had served a secretary of the Section on Surgery, 1864-1865. His resignation was refused and he was expelled from membership in 1868. He moved to New Orleans to practice ophthalmology in 1867, and died in 1872. The second series of The Journal began in St. Louis in 1884 with Adolf Alt, A graduate of Heidelberg University, who trained in ophthalmology in New York City, with Hermann Knapp, founder, editor, and publisher of the Archives of Ophthalmology. In 1918, the current third series of the American Journal of Ophthalmology, consolidated five ophthalmic publications, with Edward Jackson of Denver as editor.

    To examine the relative qualifications of expert witnesses testifying on behalf of plaintiffs vs defendants in ophthalmology malpractice litigation. Correlational and descriptive study; analysis of expert witness and physician demographic data available on several databases. The Westlaw legal database was searched for ophthalmologist expert witness testimony from January 2006 to June 2014. Physician demographic data were used as the main outcome measures, including length of experience, scholarly impact (as measured by the h-index), practice setting, and fellowship training status and were obtained from state medical licensing board sites and online medical facility and practice sites. H-indices were obtained from the Scopus database. Defendant and plaintiff expert witnesses had comparable mean years of experience (32.9 and 35.7, respectively) (P = .12) and scholarly impact (h-index = 8.6 and 8.3, respectively) (P = .42). Cases tended to resolve on the side of the expert witness with the higher h-index (P = .04). Significantly higher proportions of defendant witnesses were in academic practice (P < .05) and underwent fellowship training (P < .001). Ophthalmologist expert witnesses testifying for both plaintiffs and defendants had over 30 years of experience and high scholarly impact. Practitioners testifying on behalf of plaintiffs were statistically less likely to work in an academic setting and have subspecialty training. Scholarly impact of expert witnesses appeared to affect trial outcomes. Surgical societies should stringently police for appropriate expert witness testimony given by both plaintiff and defense experts in malpractice litigation. Copyright © 2015 Elsevier Inc.

    2016-01-01

    Abstract The process of formation of Marx line is studied in this article. Various theories have been proposed previously, in order to explain the mechanisms which lead to the development of Marx line. These theories are based on the characteristics of stained area and do not pay attention to the behavior of dye solution itself on the surface. The aim of this study is to investigate the latter behavior and introduce a new theory based on it, in order to explain the process of the Marx line formation. This study also introduces “Coffee Ring Effect” and its possible applications in explaining some ophthalmological phenomena. The effect of dye solution's behavior on the beneath surface is adopted in order to propose a novel theory. This new hypothesis is called “Anionic Dye Deposition” which was based on “Coffee Ring Effect” phenomenon. For evaluation of this theory, Evaporation pattern of Rose Bengal and fluorescein were analyzed on different surfaces. Furthermore, the effect of tear meniscus alteration on lid margin staining is studied. During the evaporation process of dye solutions, it was observed that almost all of the solute was deposited at the edge of the drop on hydrophilic surfaces. Furthermore, in the study of lid margin staining, it is observed that tear meniscus alteration during gaze affects staining pattern. This observation invalidates former hypotheses which only focus on stained surface characteristics. According to the observations in this study, it is proposed that Marx line staining occurs as a result of “anionic dye deposition” due to evaporation. PMID:27057835

  13. Redefining tissue engineering for nanomedicine in ophthalmology.

    PubMed

    Ellis-Behnke, Rutledge; Jonas, Jost B

    2011-03-01

    Working at the nanoscale means to completely rethink how to approach engineering in the body in general and in the eye in particular. In nanomedicine, tissue engineering is the ability to influence an environment either by adding, subtracting or manipulating that environment to allow it to be more conducive for its purpose. The goal is to function at the optimum state, or to return to that optimum state. Additive tissue engineering replaces cells or tissue, or tries to get something to grow that is no longer there. Arrestive tissue engineering tries to stop aberrant growth which, if left uncontrolled, would result in a decrease in function. Nano delivery of therapeutics can perform both additive and arrestive functions influencing the environment either way, depending on the targeting. By manipulating the environment at the nanoscale, the rate and distribution of healing can be controlled. It infers that potential applications of nanomedicine in ophthalmology include procedures, such as corneal endothelial cell transplantation, single retinal ganglion cell repair, check of retinal ganglion cell viability, building of nanofibre scaffolds, such as self-assembling peptides, to create a scaffold-like tissue-bridging structure to provide a framework for axonal regeneration in the case of optic nerve reconnection or eye transplantation, and ocular drug delivery. Examples of potential arrestive therapies include gene-related treatment modalities to inhibit intraocular neovascularization and to block retinal cell apoptosis. Looking towards the future, this review focuses on how nanoscale tissue engineering can be and is being used to influence that local environment. © 2010 The Authors.

    As is now the tradition, the European Southern Observatory looks back at the exciting moments of last year. 2008 was in several aspects an exceptionally good year. Over the year, ESO's telescopes provided data for more than 700 scientific publications in refereed journals, making ESO the most productive ground-based observatory in the world. ESO PR Highlights 2008 ESO PR Photo 01a/09 The image above is a clickable map. These are only some of the press releases issued by ESO in 2008. For a full listing, please go to ESO 2008 page. Austria signed the agreement to join the other 13 ESO member states (ESO 11/08 and 20/08), while the year marked the 10th anniversary of first light for ESO's "perfect science machine", the Very Large Telescope (ESO 16/08 and 17/08). The ALMA project, for which ESO is the European partner, had a major milestone in December, as the observatory was equipped with its first antenna (ESO 49/08). Also the Atacama Pathfinder Experiment (APEX) telescope impressed this year with some very impressive and publicly visible results. Highlights came in many fields: Astronomers for instance used the Very Large Telescope (VLT) to discover and image a probable giant planet long sought around the star Beta Pictoris (ESO 42/08). This is now the eighth extrasolar planet to have been imaged since the VLT imaged the first extrasolar planet in 2004 (three of eight were imaged with VLT). The VLT also enabled three students to confirm the nature of a unique planet (ESO 45/08). This extraordinary find, which turned up during their research project, is a planet about five times as massive as Jupiter. This is the first planet discovered orbiting a fast-rotating hot star. The world's foremost planet-hunting instrument, HARPS, located at ESO's La Silla observatory, scored a new first, finding a system of three super-Earths around a star (ESO 19/08). Based on the complete HARPS sample, astronomers now think that one Sun-like star out of three harbours short orbit, low

    To examine whether there is an association between scholarly impact, as measured by the h-index, academic rank, and National Institutes of Health (NIH) awards in academic ophthalmology. Retrospective analysis of NIH RePORTER and Scopus databases. Not applicable. Five hundred seventy-three NIH awards to 391 primary investigators (PIs) in ophthalmology departments were examined. Grant recipients were organized by academic rank, obtained from online listings, and h-index, calculated using the Scopus database. Non-NIH-funded faculty from 20 randomly chosen academic ophthalmology departments also were organized by rank and h-index for comparison with their NIH-funded colleagues. Scholarly impact, as measured by the h-index, and NIH funding. The h-index increased with successive academic rank among non-NIH-funded and NIH-funded faculty, as did NIH funding among the latter group. The NIH-funded faculty had higher scholarly impact, as measured by the h-index, than their non-NIH-funded PIs (h = 18.3 vs. 7.8; P <0.0001), even when considering publications only in the prior 5 years; h-index increased with increasing NIH funding ranges. The h-indices of those holding an MD degree (21.4±1.6 standard error of mean) were not statistically higher than those of PhD holders (17.9±0.6) and those with both an MD and PhD degree (18.1±1.7; P = 0.14). The h-index increases with increasing academic rank among NIH-funded and non-NIH-funded faculty in ophthalmology departments. This bibliometric is associated strongly with NIH funding because NIH-funded PIs had higher scholarly impact than their non-NIH-funded colleagues, and increasing impact was noted with higher funding. The h-index is an objective and easily calculable measure that may be valuable as an adjunct in assessing research productivity, a significant factor for academic promotion in academic ophthalmology.

    Recent reform of medical education highlights the growing concerns about the capability of the current educational model to equip medical school students with essential skills for future career development. In the field of ophthalmology, although many attempts have been made to address the problem of the decreasing teaching time and the increasing load of course content, a growing body of literature indicates the need to reform the current ophthalmology teaching strategies. Flipped classroom is a new pedagogical model in which students develop a basic understanding of the course materials before class, and use in-class time for learner-centered activities, such as group discussion and presentation. However, few studies have evaluated the effectiveness of the flipped classroom in ophthalmology education. This study, for the first time, assesses the use of flipped classroom in ophthalmology, specifically glaucoma and ocular trauma clerkship teaching. A total number of 44 international medical school students from diverse background were enrolled in this study, and randomly divided into two groups. One group took the flipped glaucoma classroom and lecture-based ocular trauma classroom, while the other group took the flipped ocular trauma classroom and lecture-based glaucoma classroom. In the traditional lecture-based classroom, students attended the didactic lecture and did the homework after class. In the flipped classroom, students were asked to watch the prerecorded lectures before the class, and use the class time for homework discussion. Both the teachers and students were asked to complete feedback questionnaires after the classroom. We found that the two groups did not show differences in the final exam scores. However, the flipped classroom helped students to develop skills in problem solving, creative thinking and team working. Also, compared to the lecture-based classroom, both teachers and students were more satisfied with the flipped classroom

    Team-based learning (TBL) is an increasingly popular teaching method in medical education. However, TBL hasn't been well-studied in the ophthalmology clerkship context. This study was to examine the impact of modified TBL in such context and to assess the student evaluations of TBL. Ninety-nine students of an 8-year clinical medicine program from Zhongshan Ophthalmic Centre, Sun Yat-sen University, were randomly divided into four sequential units and assigned to six teams with the same faculty. The one-week ophthalmology clerkship module included traditional lectures, gross anatomy and a TBL module. The effects of the TBL module on student performance were measured by the Individual Readiness Assurance Test (IRAT), the Group Readiness Assurance Test (GRAT), the Group Application Problem (GAP) and final examination scores (FESs). Students' evaluations of TBL were measured by a 16-item questionnaire. IRAT and GRAT scores were compared using a paired t-test. One-way analysis of variance (ANOVA) and subgroup analysis compared the effects among quartiles that were stratified by the Basic Ophthalmology Levels (BOLs). The BOLs were evaluated before the ophthalmology clerkship. In TBL classes, the GRAT scores were significantly higher than the IRAT scores in both the full example and the BOL-stratified groups. It highlighted the advantages of TBL compared to the individual learning. Quartile-stratified ANOVA comparisons showed significant differences at FES scores (P < 0.01). In terms to IRAT, GRAT and GAP scores, there was no significant result. Moreover, IRAT scores only significantly differed between the first and fourth groups. The FES scores of the first three groups are significantly higher than the fourth group. Gender-specific differences were significant in FES but not the IRAT.

    To compare methodologies for imputing ethnicity in an urban ophthalmology clinic. Using data from 19,165 patients with self-reported ethnicity, surname, and home address, we compared the accuracy of three methodologies for imputing ethnicity: (1) a surname method based on tabulation from the 2000 US Census; (2) a geocoding method based on tract data from the 2010 US Census; and (3) a combined surname geocoding method using Bayes' theorem. The combined surname geocoding model had the highest accuracy of the three methodologies, imputing black ethnicity with a sensitivity of 84% and positive predictive value (PPV) of 94%, white ethnicity with a sensitivity of 92% and PPV of 82%, Hispanic ethnicity with a sensitivity of 77% and PPV of 71%, and Asian ethnicity with a sensitivity of 83% and PPV of 79%. Overall agreement of imputed and self-reported ethnicity was fair for the surname method (κ 0.23), moderate for the geocoding method (κ 0.58), and strong for the combined method (κ 0.76). A methodology combining surname analysis and Census tract data using Bayes' theorem to determine ethnicity is superior to other methods tested and is ideally suited for research purposes of clinical and administrative data.

    In the context of legal requirements and scarcer resources, the implementation of a quality management (QM) model will provide a competitive advantage or a site warranty for a hospital. For 3 years, the Department of Ophthalmology in Graz has been working with the EFQM model and has now accomplished the first level quality award, namely "Committed to Excellence (C2E)". The project work towards achieving this C2E-award is described below. EFQM stands for European Foundation for Quality Management, an organization that was founded in 1989 by the EU, together with 14 leading enterprises. In the EFQM model, the maturity of an organization in terms of quality is determined through the achievement of a number of quality awards. The C2E award is the first of these awards. At the beginning of our work for the C2E level, the strengths and weaknesses of the Department of Ophthalmology were determined by means of an EFQM questionnaire. Three improvement measures with the highest impact on the performance of the clinic were identified by the questionnaire: 1. The hospitalization of a cataract patient. 2. The lack of information between the various professional parties. 3. The lack of knowledge within the professional groups of the objectives and strategy of the Department of Ophthalmology. These areas requiring improvement were targeted, addressed and improved in a 6-months project work, structured by the EFQM model. The project work as a whole, the results obtained and the corresponding written documentation were evaluated positively in a 1-day assessment by Quality Austria. The EFQM model is a challenging quality management model. After the necessary training of project members or under the supervision of experienced quality managers, the EFQM model may be successfully applied to patient care, teaching and research in a department of ophthalmology.

  12. Satellite clinics in academic ophthalmology programs: an exploratory study of successes and challenges

    PubMed Central

    2013-01-01

    Background Major academic ophthalmology departments have been expanding by opening multi-office locations (“satellites”). This paper offers a first glimpse into satellites of academic ophthalmology departments. Methods Leaders of seven medium to large, geographically diverse departments agreed to participate. One- to two-hour phone interviews were conducted to assess the features of their satellite practices. Results Success as clinical entities, profitability, and access to patients were stated goals for most satellites. In approximate descending order, refractive surgery, retina, oculoplastics, and pediatric ophthalmology were the most common subspecialties offered. Faculty staffing ranged from recruitment specifically for satellites to rotation of existing faculty. Except for a department with only one academic track, satellite doctors were a mix of tenure and mostly non-tenure track faculty. According to these department leaders, scholarly productivity of satellite faculty was similar to that of colleagues at the main campus, though research was more community-based and clinical in nature. Fellowship but little resident education occurred at satellites. Though it was agreed that satellite practices were integral to department finances, they accounted for a smaller percentage of revenues than of total departmental visits. Conclusions Satellite offices have offered access to a better payor mix and have boosted the finances of academic ophthalmology departments. Challenges include maintaining collegiality with referring community physicians, integrating faculty despite geographic distance, preserving the department’s academic “brand name,” and ensuring consistent standards and operating procedures. Satellite clinics will likely help departments meet some of the challenges of health care reform. PMID:24330741

    SOFIA, the Stratospheric Observatory for Infrared Astronomy, is a joint project between NASA and the German Aerospace Center DLR to provide infrared and sub-millimeter observing capabilities to the worldwide astronomical community. With a wide range of instruments that cover both imaging and spectroscopy, SOFIA has produced unique scientific results that could not be obtained with a ground-based facility. In this talk, I will describe highlights from a range of areas in astronomy. A particular strength of SOFIA is high resolution spectroscopy. In the mid-infrared, the instrument EXES has enabled velocity-resolved observations of solar system, interstellar, and star forming regions. The heterodyne spectrometer GREAT has been a particularly productive instrument on SOFIA, with high resolution studies of the gas in the interstellar medium. With its extremely high spectral resolution, GREAT has allowed dynamical studies of clouds and their interactions. I will highlight observations that demonstrate the infall of material in star-forming regions. SOFIA can go to where the science is. This mobility is important for localized events such as occultations. Results from the recent Pluto occultation campaign will be discussed.

    Background: This cross-sectional survey assessed the adequacy of ophthalmology teaching in undergraduate medical education and evaluated the comfort level of family medicine residents in diagnosing and managing common ophthalmic conditions. Methods: Postgraduate year 1 and 2 family medicine residents at the University of Western Ontario were recruited for this study. The main outcome measures were hours of classroom and clinic-based instruction on ophthalmology during undergraduate medical education, and the comfort level in ophthalmic clinical skills and managing various ophthalmic conditions. Results: In total, 54 (33.3%) of 162 family medicine residents responded to the survey. Residents reported an average of 27.1 ± 35.1 hours and 39.8 ± 47.1 hours of classroom and clinical ophthalmology instruction, respectively. However, most residents (80%) responded as feeling only “somewhat comfortable” or “not at all comfortable” in assessing and managing common ophthalmic conditions, including ocular emergencies, such as acute angle closure glaucoma and ocular chemical burn. A positive correlation was seen between overall comfort level and hours of classroom instruction (P < 0.05). Conclusion: The number of hours of ophthalmology training received by family medicine residents during medical school meets the International Council of Ophthalmology Task Force recommendations. However, family medicine residents appear to be uncomfortable in handling treatable but potentially sight-threatening ocular conditions. Standardizing the undergraduate medical education ophthalmology curriculum and increasing hours of ophthalmology training during postgraduate family medicine residency may be useful in bridging this gap in knowledge.

    To analyze the self-citation rate (SCR) of ophthalmology journals, determine its possible effect on a journal's impact factor (IF) and compare the SCR of subspecialty journals versus general ophthalmology journals. A retrospective consecutive study of ophthalmology journals listed in the Journal Citations Report (JCR) 2013. We retrieved these parameters from each journal's report: IF, total citations, self-citations, SCR and IF without self-citations (corrected IF). A significant correlation was detected between the number of self-citations and publications (R(2) = 86.3, p = 0.000). Subspecialty journals had a significantly higher SCR than general journals (p = 0.017). No significant difference was found in terms of IF and corrected IF between general and subspecialty journals (p = 0.260 and p = 0.108, respectively). No significant correlation between IF and SCR was detected (p = 0.099). The corrected IF was inversely correlated with SCR (R(2) = -32.6, p = 0.013). An inverse correlation was detected between SCR and IF in the 29 ophthalmology journals with the lowest IF (R(2) = -57.3, p = 0.001). Unlike other fields of medicine, the IF of an ophthalmology journal does not correlate with its SCR. Self-citation is found more often in journals with a low corrected IF and is inversely correlated with IF in the bottom half. © 2014 S. Karger AG, Basel.

  16. Breaking bad news: A communication competency for ophthalmology training programs.

    PubMed

    Hilkert, Sarah M; Cebulla, Colleen M; Jain, Shelly Gupta; Pfeil, Sheryl A; Benes, Susan C; Robbins, Shira L

    As the ophthalmology accreditation system undergoes major changes, training programs must evaluate residents in the 6 core competencies, including appropriately communicating bad news. Although the literature is replete with recommendations for breaking bad news across various non-ophthalmology specialties, no formal training programs exist for ophthalmology. There are many valuable lessons to be learned from our colleagues regarding this important skill. We examine the historic basis for breaking bad news, explore current recommendations among other specialties, and then evaluate a pilot study in breaking bad news for ophthalmology residents. The results of this study are limited by a small number of residents at a single academic center. Future studies from multiple training programs should be conducted to further evaluate the need and efficacy of formal communication skills training in this area, as well as the generalizability of our pilot training program. If validated, this work could serve as a template for future ophthalmology resident training and evaluation in this core competency. Copyright © 2016 Elsevier Inc. All rights reserved.

    Since its initial introduction in the mid-1990 s, retinotopic mapping of the human visual cortex, based on functional magnetic resonance imaging (fMRI), has contributed greatly to our understanding of the human visual system. Multiple cortical visual field representations have been demonstrated and thus numerous visual areas identified. The organisation of specific areas has been detailed and the impact of pathophysiologies of the visual system on the cortical organisation uncovered. These results are based on investigations at a magnetic field strength of 3 Tesla or less. In a field-strength comparison between 3 and 7 Tesla, it was demonstrated that retinotopic mapping benefits from a magnetic field strength of 7 Tesla. Specifically, the visual areas can be mapped with high spatial resolution for a detailed analysis of the visual field maps. Applications of fMRI-based retinotopic mapping in ophthalmological research hold promise to further our understanding of plasticity in the human visual cortex. This is highlighted by pioneering studies in patients with macular dysfunction or misrouted optic nerves. © Georg Thieme Verlag KG Stuttgart · New York.

    Bioengineering aims to produce functional tissue replacements to repair defects and has been widely investigated over the past few decades. We aimed to review the available literature on the application of tissue engineering in ophthalmology, with a particular focus on ophthalmic plastic surgery and potential applications for eyelid reconstruction. A literature search was performed on the MEDLINE database using the keywords "bioengineering," "tissue engineering," and "ophthalmology." Articles written in English were included. There is a substantial body of work on tissue engineering of the cornea. Other structures in ophthalmology investigated include the conjunctiva, lacrimal gland, and orbital bone. We also discuss the potential application of tissue engineering in eyelid reconstruction. Tissue engineering represents the future of regenerative and reconstructive medicine, with significant potential applications in ophthalmic plastic surgery.

    Ophthalmology departments can play a unique role in providing care for at-risk patients. This study analyzed the age, gender, and socioeconomic measures for 267,286 unique African American patients seen at University of Pennsylvania Health System (UPHS). Patients seen by the Ophthalmology Department (n=33,801) were older and more likely to be from impoverished zip codes than those seen by other UPHS specialists. These results hint at several inherent advantages of ophthalmology departments in recruiting older, disadvantaged patients to their clinics. We found that supplementing this advantage with strong patient relationships, involvement of community leaders, and customized outreach efforts was key to overcoming access-to-care issues and to reaching these patients. This provides ophthalmologists with a unique opportunity to capture and refer systemic conditions with ocular manifestations and to possibly reduce disparities such as post-hospitalization readmission and mortality observed disproportionately in impoverished populations.

    Lectures with many participants are considered inefficient and ophthalmology is seen as "not so important" for those studying medicine. We wondered about the students' view on this subject. During the last lesson of a two-week-series of lectures together with the written test, 337 students of two consecutive semesters received a questionnaire with specific questions concerning ophthalmology lectures. 257 questionnaires (76 %) were returned. The students claimed that the lecture itself contributed most of the knowledge for their later medical practice, more than books, scripts, internet etc. Interactivity was welcome, audience response systems were appreciated. Personal contact to the lecturers was considered less important, a variation of the lecturers was considered advantageous. It would be seen as a serious loss if the ophthalmology lecture were abolished. These results contradict clearly the concept of the unimportance of lectures with many participants and contradict as well tendencies not to teach "small" specialties in separate lectures.

    To compare clinical trials published in Brazilian journals of ophthalmology and in foreign journals of ophthalmology with respect to the number of citations and the quality of reporting [by applying the Consolidated Standards for Reporting Trials (CONSORT) statement writing standards]. The sample of this systematic review comprised the two Brazilian journals of ophthalmology indexed at Science Citation Index Expanded and six of the foreign journals of ophthalmology with highest Impact Factor® according ISI. All clinical trials (CTs) published from January 2009 to December 2010 at the Brazilians journals and a 1:1 randomized sample of the foreign journals were included. The primary outcome was the number of citations through the end of 2011. Subgroup analysis included language. The secondary outcome included likelihood of citation (cited at least once versus no citation), and presence or absence of CONSORT statement indicators. The citation counts were statistically significantly higher (P<0.001) in the Foreign Group (10.50) compared with the Brazilian Group (0.45). The likelihood citation was statistically significantly higher (P<0.001) in the Foreign Group (20/20 - 100%) compared with the Brazilian Group (8/20 - 40%). The subgroup analysis of the language influence in Brazilian articles showed that the citation counts were statistically significantly higher in the papers published in English (P<0.04). Of 37 possible CONSORT items, the mean for the Foreign Group was 20.55 and for the Brazilian Group was 13.65 (P<0.003). The number of citations and the quality of reporting of clinical trials in Brazilian journals of ophthalmology still are low when compared with the foreign journals of ophthalmology with highest Impact Factor®.

    To assess the value of current selection criteria and additional factors as predictors of performance in an ophthalmology residency training program. A retrospective study. Data were collected from the files of 166 residents who were collectively trained in an ophthalmology residency program from 2000 to 2013. The program's selection criteria included medical school grade point average (GPA), Saudi licensing examination (SLE) score, multiple-choice question ophthalmology selection (MCQ) examination score, and interview mark. Indicators of performance included average scores in the promotion examination for 4 years of training (average R), King Saud University fellowship examination (KSU) score, and Saudi Board in Ophthalmology examination (SBO) score. An average of KSU and SBO scores was also used as a performance indicator. Times of program completion and average performance score across all years in the residency program were used as second-level indicators of performance. There were strong correlations between the MCQ examination score and each training performance indicator (average R, KSU score, SBO score, and average of KSU and SBO scores; p = 0.002, 0.008, 0.05, and 0.002, respectively). The interview mark correlated well with average R (p = 0.001) but not with other indicators. The MCQ examination score and the interview mark were the only predictors of second-level indicators of performance (p = 0.009 and 0.029, respectively). The MCQ examination score and interview mark were the 2 best predictors of performance as an ophthalmology resident. GPA and SLE score were poor predictors of performance.

  15. Highlighting Titan's Hazes

    NASA Image and Video Library

    2017-08-11

    NASA's Cassini spacecraft looks toward the night side of Saturn's moon Titan in a view that highlights the extended, hazy nature of the moon's atmosphere. During its long mission at Saturn, Cassini has frequently observed Titan at viewing angles like this, where the atmosphere is backlit by the Sun, in order to make visible the structure of the hazes. Titan's high-altitude haze layer appears blue here, whereas the main atmospheric haze is orange. The difference in color could be due to particle sizes in the haze. The blue haze likely consists of smaller particles than the orange haze. Images taken using red, green and blue spectral filters were combined to create this natural-color view. The image was taken with the Cassini spacecraft narrow-angle camera on May 29, 2017. The view was acquired at a distance of approximately 1.2 million miles (2 million kilometers) from Titan. Image scale is 5 miles (9 kilometers) per pixel. https://photojournal.jpl.nasa.gov/catalog/PIA21625

  16. Recent Highlights from VERITAS

    2016-04-01

    VERITAS is a ground-based gamma-ray observatory consisting of an array of four atmospheric Cherenkov telescopes located in southern Arizona, USA. VERITAS carries out an extensive observation program of the gamma-ray sky at energies above 0.1 TeV. Observations of Galactic and extragalactic sources in the TeV band are sensitive probes of the highly energetic processes occurring in these objects. Observations by VERITAS of the Galactic center and nearby dwarf spheroidal galaxies provide constraints on particle dark matter with masses above a few hundred GeV. VERITAS observations also provide constraints on fundamental physics and cosmology, such as probing the history of galaxy formation and studying Lorentz invariance violation (LIV). The majority of the sources detected by VERITAS are active galactic nuclei (AGN), with gamma-ray emission originating in their relativistic jets. TeV observations of AGN help us constrain models of particle acceleration and energy dissipation in relativistic jets, and the size and location of the gamma-ray emission region. Galactic sources at TeV energies include supernova remnants, pulsar wind nebulae, and binary systems, and TeV emission is a key diagnostic of the highly energetic particles in these objects. VERITAS observations provide important clues on the origin of cosmic rays and on particle acceleration in supernova blast shocks and relativistic pulsar wind-termination shocks. In this article I will present some highlights of particle-astrophysics measurements made with VERITAS.

  1. Qualitative outcome assessment and research on chronic disease management in general practice. Highlights from a keynote lecture, EGPRN May 2011, Nice.

    Griffiths, Frances

    2012-03-01

    At its 2011 conference in Nice, France, the European General Practice Research Network (EGPRN), considered the issue of Relevant Outcome Measures in General Practice Research into Chronic Diseases. This paper, which is adapted from a keynote lecture given during that conference, considers the role of qualitative outcome assessments in research. Such assessments have a great deal in common with the patient-centred approach of general practice as they can capture the overall state of a patient rather than capturing only certain aspects. Research suggests that patients can be categorized, based on qualitative outcome assessment, and over time might change category. This approach to assessment brings to our attention alternative ways of considering the future: future as currently being made or future as predictable, at least to some extent. Although general practice needs the evidence from research that predicts the future, it also needs to engage in research that seeks to understand patients as they make their future, and to understand the impact of clinical interventions on this process.

    An effort is underway to provide greater visibility within NASA headquarters, and to those who provide funding to NASA, of the outstanding work that is being performed by scientists involved in the Solar System Exploration Research and Analysis Programs, most of whom are DPS members. In support of this effort, a new feature has been developed for the NASA Headquarters Solar System Exploration Division web site whereby researchers can provide a synopsis of their current research results. The site (http://solarsystem.nasa.gov/spotlight/ - Username: your email address Password: sse) is an online submission area where NASA-funded scientists can upload the results of their research. There they provide their contact information, briefly describe their research, and upload any associated images or graphics. The information is available to a limited number of reviewers and writers at JPL. Each month, one researcher's work will be chosen as a science spotlight. After a writer interviews the scientist, a brief Power Point presentation that encapsulates their work will be given to Dr. Colleen Hartman at NASA headquarters. She will then present the exciting findings to Associate Administrator for Space Science, Dr. Ed Weiler. The information from some of these highlights can serve as a basis to bring Principal Investigators to NASA Headquarters for exposure to media through Space Science Updates on NASA television. In addition, the science results may also be incorporated into briefing material for the Office of Management and Budget and congressional staffers. Some spotlights will also be converted into feature stories for the Solar System Exploration website so the public, too, can learn about exciting new research. The site, http://solarsystem.nasa.gov/, is one of NASA's most visited. Over the past decade, there has been a trend of flat budgets for Research and Analysis activities. By giving more visibility to results of Solar System research, our goal is to encourage

    2011-01-01

    Purpose To develop a help-wanted index (HWI) to measure trends in marketplace demand for ophthalmologists, to identify the economic drivers of demand, and to determine the impact of economic recessions on the ophthalmology job market. Methods Review of physician recruitment advertisements appearing in the journals Ophthalmology, American Journal of Ophthalmology, and Archives of Ophthalmology from January 1980 through June 2006. Results Over the 26-year study period a consistent increase in the demand for subspecialists (31% of HWI in 1980 to 80% in 2005) was noted. There was also an increase in the demand for academic ophthalmologists. The need for academic ophthalmologists seems to be correlated with national research expenditure and stock market gains (P = .00191), whereas demand for private practice ophthalmologists seems to be correlated with the national economic well-being, as measured by gross domestic product (GDP) (P < .001). Residency applicants (P = .0128) and fellowship applicants (P = .0198) respond to marketplace demand. During the recessions, the demand for ophthalmologists fell 2 to 3 years after the economic downturn. Conclusions Over a 26-year period, HWI data suggest an increased need for subspecialists and academic ophthalmologists. The ophthalmic community has been quick to respond to marketplace demand. National research expenditure, stock market gains, GDP, and discretionary health care expenditure have been associated with the ophthalmology job market. These factors tend to decline with economic recessions. Historically, the demand for ophthalmologists has declined 2 to 3 years following a recession, which may mean lower demand in the near future, given the recent recession. PMID:22253483

    The 10th National Congress of the Italian Association of Nuclear Medicine and Molecular Imaging (AIMN) took place in Rimini on March 18-21, 2011 under the chairmanship of Professor Stefano Fanti. The program was of excellent quality and put a further step for the settlement of the standardized AIMN congress structure. A large industrial exhibition demonstrated the latest technological innovations and developments within the field. The congress was a great success with more than 1100 total participants and more than 360 abstracts received. Of these, 40 abstracts were accepted for oral and 285 for poster presentations. The original investigations presented were related to different areas of nuclear medicine and molecular imaging, with particular focus on advances in instrumentation and data processing, progress in radiochemistry and pharmacy, novel diagnostics and therapeutics, and new insights in well established areas of clinical application, such as oncology, cardiology, neurology, psychiatry, endocrinology, paediatrics, and infection and inflammation. Noteworthy, several presentations at this congress, focusing on quantitative interpretation of the imaging data and on pragmatic endpoints, such as adverse outcomes, identified when nuclear medicine procedures achieved clinical effectiveness for patient care and patient management and further demonstrated that nuclear medicine plays a crucial role in the contemporary medical scenario. This highlights lecture is only a brief summary of the large amount of data presented and discussed, which can be found in much greater detail in the congress abstract book, published as volume 55, supplement 1 of the Q J Nucl Med Mol Imaging in April 2011.

    Skin plays a protective role against the loss of water and external aggression, including mechanical stresses. These crucial functions are ensured by different cutaneous layers, particularly the stratum corneum (SC). During aging, the human skin reveals some apparent modifications of functionalities such as a loss of elasticity. Our investigations aimed at demonstrating that Raman microspectroscopy, as a label-free technique with a high molecular specificity, is efficient to assess in vivo the molecular composition of the skin and the alterations underwent during aging. Our approach was based on a search for correlation between Raman data collected on healthy female volunteers of different ages (from 21 to 70 years old) by means of a remote confocal Raman and skin firmness measurements used as a reference method. Raman and biometric data were then submitted to a partial least square (PLS)-based data processing. Our experiments demonstrated the potential of Raman microspectroscopy to provide an objective in vivo assessment of the skin "biological age" that can be very different from the "chronological age" of the person. In addition, Raman features sensitive to the elasticity and the fatigability of the SC were highlighted. Thereafter, calibration transfer functions were constructed to show the possibility to compare the results obtained during two distinct measurement campaigns conducted with two Raman probes of the same conception. This approach could lead to several interesting prospects, in particular by objectifying the effects of dermocosmetic products on the superficial layers of the skin and by accessing some underlying molecular mechanisms.

    Ophthalmological indications for traditional hospitalizations are not clearly established and should be updated with respect to both healthcare quality and economic considerations. We therefore analyzed the data of patients hospitalized in an ophthalmology department. We prospectively analyzed the medical and socioeconomic charts of all patients hospitalized during a 2-month period (December 2006 and January 2007) in a single ophthalmology department. Over the 2 months, 349 patients were admitted (mean stay, 3 days), 324 of whom were operated. The main causes of admission were retinal detachments (n=103), injuries (n=33), endothelial cell failure (n=27), cataract (n=27), high ocular pressure (n=23), and corneal abscess (n=17). Admission was mainly guided by the surgeon's habits (n=135, 39%) and was not medically relevant but was generally motivated by financial considerations. Other hospital admissions were medically justified (intravenous injections, head positioning) but the hospitalization of patients living far from the hospital (n=46; 13%) could be limited by the development of housing made available to patients. Ophthalmological hospitalization is not always medically relevant and often is based on financial or housing constraints. More than half of the classical admissions should be switched to ambulatory patient care by adapting financial compensations to surgical costs or providing outpatient housing.

    Background Egypt has one of the highest prevalence of hepatitis C virus (HCV) worldwide. Ophthalmological side effects are recognized complications of interferon (IFN) therapy. This study aimed to evaluate IFN-induced ophthalmological manifestations in patients receiving PEGylated interferon (PEG IFN) and ribavirin (RBV) and to assess the effect of IFN duration, response and systemic risk factors on the severity. Methods We retrospectively analyzed 100 patients with chronic HCV who were candidates for PEG-IFN and RBV therapy. All patients were subjected to clinical and ophthalmological examination, laboratory investigations, abdominal ultrasound, colored fundus photography and fundus fluorescein angiography, follow up was made at weeks 12, 24, and 48 of treatment. Results IFN-induced retinopathy had been found in (9/100; 9%), 5 (5/9; 55.5%) of them had bilateral lesions, (3/9; 33.3%) were treatment responders and (6/9; 66.6%) non responders. The time of retinopathy appearance was mainly at W12. Retinopathy was asymptomatic in most of the affected patients (7/9; 77.77%) and reversible, cotton wool spots was the major associated sign. Patients with older age, DM and or HTN, and non-responders to antiviral therapy were associated with more severe retinopathy. Conclusions Retinopathy is not a rare complication of IFN therapy for chronic HCV infection, but fortunately it’s asymptomatic and reversible. Ophthalmological assessment at base-line and at follow up during IFN treatment is very important. PMID:27275462

    The field of ophthalmology has a number of unique features compared with other medical and surgical specialties regarding clinical workflow and data management. This has important implications for the design of electronic health record (EHR) systems that can be used intuitively and efficiently by ophthalmologists and that can promote improved quality of care. Ophthalmologists often lament the absence of these specialty-specific features in EHRs, particularly in systems that were developed originally for primary care physicians or other medical specialists. The purpose of this article is to summarize the special requirements of EHRs that are important for ophthalmology. The hope is that this will help ophthalmologists to identify important features when searching for EHR systems, to stimulate vendors to recognize and incorporate these functions into systems, and to assist federal agencies to develop future guidelines regarding meaningful use of EHRs. More broadly, the American Academy of Ophthalmology believes that these functions are elements of good system design that will improve access to relevant information at the point of care between the ophthalmologist and the patient, will enhance timely communications between primary care providers and ophthalmologists, will mitigate risk, and ultimately will improve the ability of physicians to deliver the highest-quality medical care.

    To examine the characteristics of US medical students applying for ophthalmology residency and to determine the predictors of matching. A retrospective case series. A total of 3435 medical students from the United States who applied to an ophthalmology residency program from 2003 to 2008 were included. Matched and unmatched applicants were compared and stratified by predictor variables, including United States Medical Licensing Examination (USMLE) Step 1 score, Alpha Omega Alpha (AOA) status, medical school reputation, and medical school geographic region. Differences in proportions were analyzed using the Fisher exact test. Logistic regression was used to determine the predictors of successful matching. Successful matching to an ophthalmology program. The majority of applicants (72%, 2486/3435) matched in ophthalmology. In multivariate analysis, AOA membership (odds ratio [OR], 2.6, P<0.0001), USMLE score (OR, 1.6; P<0.0001), presence of an ophthalmology residency at medical school (OR, 1.4; P = 0.01), top 25 medical school (OR, 1.4; P<0.03), top 10 medical school (OR, 1.6; P<0.02), and allopathic degree (OR, 4.0; P<0.0001) were statistically significant predictors of matching. Approximately 60% (1442/2486) of applicants matched to the same geographic region as their medical school. Applicants were more likely to match at a program in the same geographic region as their medical school than would be predicted by chance alone (P<0.0001). In multivariate analysis, higher USMLE score (OR, 0.9; P<0.0001) and top 10 medical school (OR, 0.7; P = 0.027) were statistically significant predictors of matching to outside the geographic region as one's medical school. The majority of applicants applying for an ophthalmology residency position match successfully. Higher performance on quantitative metrics seems to confer an advantage for matching. The majority of applicants match at a residency program within the same geographic region as one's medical school. Copyright © 2013

    Neuro-ophthalmology, as an interdisciplinary, covers at least three disciplines- ophthalmology, neurology and neurosurgery. With limited knowledge in each discipline, doctors often make misdiagnoses for neuro-ophthalmology diseases. Therefore, it is imperative to abandon the distinction between disciplines and combine all the knowledge to diagnose and treat patients in patterns of holistic integrated medicine in order to effectively improve the diagnosis and treatment of neuro-ophthalmology.

    Women in ophthalmology are growing in number and have made strides in traditional metrics of professional achievement. Professional ties to industry represent another potential means of career advancement, recognition, and income. To report the representation of women among ophthalmologists receiving industry remuneration for research, consulting, honoraria, grants, royalties, and faculty/speaker roles. In this observational, retrospective study, the Centers for Medicare and Medicaid Services Open Payments database for payments to ophthalmologists by biomedical companies was reviewed for representation, median payments, and mean payments by women and men for industry relationships in 2013 and 2014. The analysis was performed from July 2015 to November 2015. The primary outcome measures were percentage representation of women vs men overall and in industry research, consulting, speaking roles, royalties and licenses, grants, services other than consulting, and honoraria. Secondary outcome measures included mean and median payments from industry to female vs male ophthalmologists. In 2013, 4164 of 21 380 (19.5%) ophthalmologists were women, and of 1204 ophthalmologists analyzed for industry payments, 176 (4.2%) women had industry ties compared with 1028 (6%) men (P < .001). Mean payments to women were $11 419 compared with $20 957 for men (P = .001), and median payments to women were $3000 compared with $4787 for men (P = .007). In 2013, women were underrepresented among ophthalmologists receiving industry payments for research (49 of 462 [10.6%]), consulting (96 of 610 [15.7%]), honoraria (3 of 47 [6.4%]), industry grants (1 of 7 [14.3%]), royalties and licenses (1 of 13 [7.7%]), and faculty/speaker roles (2 of 48 [4.2%]). In 2014, 4352 of 21 531 (20.2%) of ophthalmologists were women. Of 1518 ophthalmologists analyzed for industry payments, 255 (6%) women had industry ties compared with 1263 (7.4%) men (P < .001).

    Over the last two decades, the scope of our laser research has grown immensely. The small, low-power laser systems of our early days have given way to laser systems of record-breaking size and power. Now we are focusing our activities within the target physics and laser science programs to support the ignition and gain goals of the proposed glass-laser National Ignition Facility. In our laser isotope separation work, we completed the most important set of experiments in the history of the AVLIS Program in 1993, which culminated in a spectacularly successful run that met or exceeded all our objectives. We are also developing lasers and laser-related technologies for a variety of energy, commercial, and defense uses. On the horizon are transfers of important technologies for waste treatment, x-ray lithography, communications and security, optical imaging, and remote sensing, among others.

    Due to demographic change and societal transformation the number of elderly persons living in retirement homes is growing in Germany. Access to health care is more complicated in the setting of nursing homes. Different regional studies suggest unmet ophthalmological health care needs in institutionalized elderly people. This study assessed the current ophthalmological health care structure and supply status in nursing homes in Germany. This prospective, multicenter cross-sectional study was conducted by 14 study centers in Germany. Elderly people living in 32 nursing homes were included after approval by the local institutional review boards. A standardized examination was performed which included a detailed medical and ocular history, refraction, visual acuity testing, tonometry, biomicroscopy and dilated funduscopy. Unmet ophthalmological health care needs were documented and the data were analyzed descriptively and via logistic regression modelling. A total of 600 participants (434 women and 166 men) aged 50-104 years were examined of which 368 (61%) had ophthalmological conditions requiring treatment. The most prevalent findings were cataracts (315; 53%), disorders of the eyelids (127; 21%), dry eye disease (57; 10%) and posterior capsule opacification (43; 7%). In 63 (11%) of the participants glaucoma was suspected and 55 (9%) of the examined population had a known diagnosis of glaucoma, of whom one third was not on any or on insufficient anti-glaucomatous therapy. 236 (39%) showed signs of age-related macular degeneration (AMD). Only 52% of the examined cohort had been examined by an ophthalmologist within the last 5 years and 39% stated that they would currently not be able to consult an ophthalmologist. Reported barriers were mainly transport and lack of support. This study demonstrates considerable unmet ophthalmological health care needs of the institutionalized elderly in Germany. Novel and reformed models of specialist care provision have to be

    The research work has been concerned on the studies and development of electrochemical polishing in the magnetic field (MEP) in comparison with the standard electropolishing methods performed without stirring (EP) and the process with the forced electrolyte mixing (MIX). Advanced techniques were used in the studies, to measure the effects of the surface treatment. They are as follows: scanning electron microscopy (SEM/EDS), X-ray Photoelectron Spectroscopy (XPS), Secondary Ion Mass Spectroscopy (SIMS), surface roughness, and nanoindentation measurements. For the corrosion studies, the electrochemical methods were used, such as: open circuit potential OCP, potentiodynamic curves PC, and electrochemical impedance spectroscopy EIS measurements. The MEP process is advised mainly due to the opportunity to enrich the surface layer with the chromium compounds (austenitic stainless steels), or titanium compounds (CP Ti Grade 2, Nitinol). The surface layers of biomaterials after MEP process contain much lower amount of carcinogenic compounds, like chromium VI oxidation stage (Cr6+) (austenitic stainless steels) and nickel compounds (austenitic stainless steel & Nitinol) versus those ones obtained after EP & MIX treatments. It is interesting that apart from the significant modification of the surface layer obtained after MEP, also mechanical properties, such as nanohardness, modulus of elasticity, and mechanical resistance to bending and torsion, undergo considerable advantageous changes. All they make the MEP process very promising for application in many clean industries, such as medical equipment and devices, electronics, food industry, etc.

    The purpose of this review is to summarize new interesting findings in both research and clinical practice of nonhymenoptera anaphylaxis with particular emphasis on food and drug allergy. Recent findings include some aspects of crossreactivity among betalactams, nonsteroidal anti-inflammatory drugs with special attention to an immunogenic metabolite of diclofenac and the mode of diclofenac-induced basophil degranulation. Also, new insights into the sometimes atypical anaphylaxis-like reactions after administration of monoclonal antibodies and the immunologic response to these molecules will be discussed, as well as the role of low-dose pholcodine exposure on the development of sensitization to neuromuscular blocking agents. In food-related anaphylaxis, a significant increase of incidents has been observed over the last few years, especially among children of less than 5 years of age. Unfortunately, the severity of subsequent reactions cannot be predicted from the reaction history. Tree nuts and peanuts are the most important elicitors of fatal food-induced anaphylaxis. In food-related anaphylaxis, prospectively evaluated marker allergens that are indicative of a potential anaphylactic reaction are still lacking. The drug groups covered in this review are of special interest either due to their prominent role as allergens or due to new findings.

    Energy means development, and access to energy and electricity should be possible for everyone. The energy challenge for the years to come is to have a sustainable energy supply and after the week spent in Varenna it is clear that "sustainable" cannot be identified with green gas emission reduction only: it has to be an energy supply system respectful of the environment and the humankind, able to provide reliable and affordable energy to the whole world population. This is definitely not an easy challenge: no single energy technology will suffice to safeguard our future and any possible solution has to be exploited at its best, from renewable to nuclear energy, from clean fossil fuels to biofuels. Last but not least, it is the energy efficiency that, given the actual technology, may give the most important and immediate contribution to this challenge. Meanwhile researchers must examine a broad range of options and develop different kinds of technologies: only new investments on R&D can allow to meet the growing demand for energy in a responsible, equitable, and sustainable way.

    As part of the Fundamental Aeronautics Program and a collaborative effort with Boeing, and Lockheed Martin this past year a series of sonic boom test were completed in the NASA Ames Unitary Plan Wind Tunnel (UPWT). One of the goals was to develop new test techniques and hardware for measuring sonic boom signatures in the transonic and supersonic regimes. Data for various model designs and configurations were collected and will be used to validate CFD predictions of sonic boom signatures. Reactivation of the NASA Ames Mitsubishi compressor system was completed this past year. The compressor is intended to replace and augment the existing UPWT Clark Compressor as the primary Make Up Air (MUA) source. The MUA system provides air and vacuum pumping capability to the Ames UPWT. It will improve productivity and reliability of the UPWT as a vital testing and research facility for the U.S. aerospace industry and NASA. Funding for this task was provided from the American Recovery Investment Act (ARRA). Installation and validation of a Noncontact Stress Monitoring System (NSMS) for the 3-stage compressor was completed at the 11-foot Transonic Wind Tunnel. The system, originally developed at AEDC, consists of 36 pairs of LED light sources with optic beam send and receive probes along a 1-per rev signal. The new system allows for continuous monitoring and recording of compressor blade bending and torsion stress during normal test operations. A very unusual test was completed in the 11 FT TWT to acquire aerodynamic and flow field data for the Crew Exploration Vehicle (CEV) Parachute Assembly System (CPAS) to validate CFD methods and tools. Surface pressure distribution measurements and velocity measurements in the wake of the command module back to the drogues parachute location were acquired. Testing methods included Particle Image Velocimetry (PIV), Pressure Sensitive Paint (PSP), Schlieren Infrared Imaging (IR) and boundary layer survey and skin friction.

    To describe what information is or is not included in health care claims data, provide an overview of the main advantages and limitations of performing analyses using health care claims data, and offer general guidance on how to report and interpret findings of ophthalmology-related claims data analyses. Systematic review. Not applicable. A literature review and synthesis of methods for claims-based data analyses. Not applicable. Some advantages of using claims data for analyses include large, diverse sample sizes, longitudinal follow-up, lack of selection bias, and potential for complex, multivariable modeling. The disadvantages include (a) the inherent limitations of claims data, such as incomplete, inaccurate, or missing data, or the lack of specific billing codes for some conditions; and (b) the inability, in some circumstances, to adequately evaluate the appropriateness of care. In general, reports of claims data analyses should include clear descriptions of the following methodological elements: the data source, the inclusion and exclusion criteria, the specific billing codes used, and the potential confounding factors incorporated in the multivariable models. The use of claims data for research is expected to increase with the enhanced availability of data from Medicare and other sources. The use of claims data to evaluate resource use and efficiency and to determine the basis for supplementary payment methods for physicians is anticipated. Thus, it will be increasingly important for eye care providers to use accurate and descriptive codes for billing. Adherence to general guidance on the reporting of claims data analyses, as outlined in this article, is important to enhance the credibility and applicability of findings. Guidance on optimal ways to conduct and report ophthalmology-related investigations using claims data will likely continue to evolve as health services researchers refine the metrics to analyze large administrative data sets.

UHCO's affiliated clinics include multidisciplinary centers staffed by optometrists: the Frost Eye Clinic (HIV multidisciplinary care), Good Neighbor Health Clinic and Rusk School Health Promotion Project (indigent multidisciplinary care). These centers can converse on line with eyecare professionals. Large sites interested in low vision/visual rehabilitation include: The Institute for Rehabilitation and Research (TIRR), the Social Security Hospital (Lima, Peru), the Matagorda General Hospital and the Quentin Mease Hospital. These sites, do offer quality care but require visual rehabilitation programs provided by UHCO. These sites also provide exposure to pathology for the students. A residency program trains optometrists in Telemedicine. The research program focuses on optics and imaging necessary to diagnose glaucoma, diabetic retinopathy, and neuro-ophthalmic disorders through Telemedicine. UHCO supports the advancement of standards in tele-eyecare.

    To examine the efficacy of various disinfection methods for reusable tonometer prisms in eye care and to highlight how disinfectants can damage tonometer tips and cause subsequent patient harm. Literature searches were conducted last in October 2016 in the PubMed and the Cochrane Library databases for original research investigations. Reviews, non-English language articles, nonophthalmology articles, surveys, and case reports were excluded. The searches initially yielded 64 unique citations. After exclusion criteria were applied, 10 laboratory studies remained for this review. Nine of the 10 studies used tonometer prisms and 1 used steel discs. The infectious agents covered in this assessment include adenovirus 8 and 19, herpes simplex virus (HSV) 1 and 2, human immunodeficiency virus 1, hepatitis C virus, enterovirus 70, and variant Creutzfeldt-Jakob disease. All 4 studies of adenovirus 8 concluded that after sodium hypochlorite (dilute bleach) disinfection, the virus was undetectable, but only 2 of the 4 studies found that 70% isopropyl alcohol (e.g., alcohol wipes or soaks) eradicated all viable virus. All 3 HSV studies concluded that both sodium hypochlorite and 70% isopropyl alcohol eliminated HSV. Ethanol, 70% isopropyl alcohol, dilute bleach, and mechanical cleaning all lack the ability to remove cellular debris completely, which is necessary to prevent prion transmission. Therefore, single-use tonometer tips or disposable tonometer covers should be considered when treating patients with suspected prion disease. Damage to tonometer prisms can be caused by sodium hypochlorite, 70% isopropyl alcohol, 3% hydrogen peroxide, ethyl alcohol, water immersion, ultraviolet light, and heat exposure. Disinfectants can cause tonometer tips to swell and crack by dissolving the glue that holds the hollow tip together. The tonometer tip cracks can irritate the cornea, harbor microbes, or allow disinfectants to enter the interior of the tonometer tip. Sodium hypochlorite

    Thousands of articles have been devoted to examine different types of biosorbents and their use in cleaning polluted waters. An important objective of some studies has been the identification of the biosorption mechanisms. This type of investigation is not always performed, as it can only be done if scientists are aware of all mechanisms that, at least theoretically, control the removal of the target substances. Mistakes are often made, even in highly cited review articles, where biosorption mechanisms are named and/or grouped. The aim of this article is to highlight errors and inaccuracies as well as to discuss different classification systems of the biosorption mechanisms. This article serves as a guide, as well as a platform for discussion among researchers involved in the investigation of biosorbents, in an effort to avoid reproducing errors in subsequent articles.

Future research is needed to clarify the interaction of these factors for better understanding of vitiligo pathogenesis and subsequent successful treatment. PMID:25789295

    To establish the practice patterns of the members of the Canadian Ophthalmological Society (COS) in cataract surgery. Web-based questionnaire. Members of the COS indicating practice focus to be cataract surgery. In January 2011 an e-mail with a link to Fluid Surveys was sent from the COS office to the 292 members who had indicated their practices' focus to be cataract surgery. A reminder e-mail was sent 3 weeks later. Approval for the survey was obtained from the Regina Qu'Appelle Health Region Research Ethics Board. All responses were collected anonymously. There were 92 responses (31.5%). In 2009, the response rate was 20.7%, and in 2010 it was 32.5%. The results of the 3 surveys were compared. There was a gradual increase in the use of topical-only anaesthesia, in the number of days during which the nonsteroidal anti-inflammatory drug (NSAID) eye drops were used preoperatively, and in the use of multifocal and toric intraocular lenses. Postoperatively, the use of an NSAID eye drop alone remained unchanged, but there was a decrease in the use of steroid eye drops alone and a corresponding increase in the use of a combination steroid and NSAID eye drop. Over the past 3 years the majority of the practice patterns in cataract surgery by the members of the Canadian Ophthalmological Society have remained unchanged. However, there were certain areas where definite trends were noted. Copyright © 2012 Canadian Ophthalmological Society. Published by Elsevier Inc. All rights reserved.

    To evaluate innovative educational strategies that help optimize ophthalmology teaching in a crowded medical curriculum. The knowledge acquisition and perceptions of medical students undertaking the revised competency-based curriculum were compared with the prior content-based curriculum within the Sydney Medical Program. A mixed-methods research design was employed to include both quantitative and qualitative dimensions in evaluating the revised curriculum with medical students (n = 328) undergoing their ophthalmology rotation. Quantitative evaluation was performed with a 20-item multiple choice pre- and post-test of ophthalmic knowledge. A 12-month follow-up test was readministered to compare the long-term retention rate of graduates. Qualitative evaluation was measured with student satisfaction questionnaires. In the original curriculum there was an improvement of 19.9% from pre- to post-test scores [2.15; 95% confidence interval (CI), 1.35-2.94; P < 0.001] and a greater improvement of 31.6% from pre- to post-test (3.50; 95% CI, 3.03-3.97; P < 0.001) in the revised curriculum. When assessing retained knowledge at 12 months, students from the revised curriculum scored 11.5% higher than students from the original curriculum (1.56; 95% CI, 0.42-2.71; P = 0.008). In addition, qualitative feedback also improved, with the rotation being highly valued. The revised ophthalmic curriculum resulted in an increase in academic performance and a higher degree of student satisfaction. Given the gradual decline of ophthalmic education in the standard medical school curriculum, our results are timely in providing guidance for minimum ophthalmic curriculum exposure and strategies to improve ophthalmic education in medical schools.

    This study reviews the evidence behind simulation-based surgical training of ophthalmologists to determine (1) the validity of the reported models and (2) the ability to transfer skills to the operating room. Simulation-based training is established widely within ophthalmology, although it often lacks a scientific basis for implementation. We conducted a systematic review of trials involving simulation-based training or assessment of ophthalmic surgical skills among health professionals. The search included 5 databases (PubMed, EMBASE, PsycINFO, Cochrane Library, and Web of Science) and was completed on March 1, 2014. Overall, the included trials were divided into animal, cadaver, inanimate, and virtual-reality models. Risk of bias was assessed using the Cochrane Collaboration's tool. Validity evidence was evaluated using a modern validity framework (Messick's). We screened 1368 reports for eligibility and included 118 trials. The most common surgery simulated was cataract surgery. Most validity trials investigated only 1 or 2 of 5 sources of validity (87%). Only 2 trials (48 participants) investigated transfer of skills to the operating room; 4 trials (65 participants) evaluated the effect of simulation-based training on patient-related outcomes. Because of heterogeneity of the studies, it was not possible to conduct a quantitative analysis. The methodologic rigor of trials investigating simulation-based surgical training in ophthalmology is inadequate. To ensure effective implementation of training models, evidence-based knowledge of validity and efficacy is needed. We provide a useful tool for implementation and evaluation of research in simulation-based training. Copyright © 2015 American Academy of Ophthalmology. Published by Elsevier Inc.

    PubMed

    Kernstock, C; Friebe, K; Tonagel, F

    2013-11-01

    Optical coherence tomography (OCT) has revolutionised ophthalmology. Due to modern instruments with extremely high resolution there are more and more applications also in neuro-ophthalmological disorders. This review gives an overview on typical changes in OCT for the following diseases: autosomal dominant optic atrophy, Leber hereditary optic neuropathy, toxic, traumatic and compressive optic neuropathy, optic nerve drusen, anterior ischaemic optic neuropathy, optic disc pit, papilledema, optic neuritis (isolated or associated with multiple sclerosis or neuromyelitis optica), neurodegenerative diseases and hereditary retinal diseases. A diagnosis exclusively based on an OCT examination is not always possible, but in several diseases there are pathognomonic changes that directly lead to the correct diagnosis. Particularly with the often complex settings in neuro-ophtalmology the OCT should be seen as a supplementary modality and not as a replacement for other techniques.

    2014-01-01

    High-frequency ultrasound is an attractive means to obtain fine-resolution images of biological tissues for ophthalmologic imaging. To solve the tradeoff between axial resolution and detection depth, existing in the conventional single-pulse excitation, this study develops a new method which uses 13-bit Barker-coded excitation and a mismatched filter for high-frequency ophthalmologic imaging. A novel imaging platform has been designed after trying out various encoding methods. The simulation and experiment result show that the mismatched filter can achieve a much higher out signal main to side lobe which is 9.7 times of the matched one. The coded excitation method has significant advantages over the single-pulse excitation system in terms of a lower MI, a higher resolution, and a deeper detection depth, which improve the quality of ophthalmic tissue imaging. Therefore, this method has great values in scientific application and medical market. PMID:25356093

    Some of the highlights of an experiment designed to study coastal atmospheric phenomena along the California coast (Coastal Waves 1996 experiment) are described. This study was designed to address several problems, including the cross-shore variability and turbulent structure of the marine boundary layer, the influence of the coast on the development of the marine layer and clouds, the ageostrophy of the flow, the dynamics of trapped events, the parameterization of surface fluxes, and the supercriticality of the marine layer.Based in Monterey, California, the National Center for Atmospheric Research (NCAR) C-130 Hercules and the University of North Carolina Piper Seneca obtained a comprehensive set of measurements on the structure of the marine layer. The study focused on the effects of prominent topographic features on the wind. Downstream of capes and points, narrow bands of high winds are frequently encountered. The NCAR-designed Scanning Aerosol Backscatter Lidar (SABL) provided a unique opportunity to connect changes in the depth of the boundary layer with specific features in the dynamics of the flow field.An integral part of the experiment was the use of numerical models as forecast and diagnostic tools. The Naval Research Laboratory's Coupled Ocean Atmosphere Model System (COAMPS) provided high-resolution forecasts of the wind field in the vicinity of capes and points, which aided the deployment of the aircraft. Subsequently, this model and the MIUU (University of Uppsala) numerical model were used to support the analysis of the field data.These are some of the most comprehensive measurements of the topographically forced marine layer that have been collected. SABL proved to be an exceptionally useful tool to resolve the small-scale structure of the boundary layer and, combined with in situ turbulence measurements, provides new insight into the structure of the marine atmosphere. Measurements were made sufficiently far offshore to distinguish between the

    Patient safety is an international public health priority. Ophthalmology scientific societies and organisations have intensified their efforts in this field. As a tool to learn from errors, these efforts have been linked to the management of medical professional liability insurance through the analysis of claims. A review is performed on the improvements in patient safety, as well as professional liability issues in Ophthalmology. There is a high frequency of claims and risk of economic reparation of damage in the event of a claim in Ophthalmology. Special complaints, such as wrong surgery or lack of information, have a high risk of financial compensation and need strong efforts to prevent these potentially avoidable events. Studies focused on pathologies or specific procedures provide information of special interest to sub-specialists. The specialist in Ophthalmology, like any other doctor, is subject to the current legal provisions and appropriate mandatory training in the medical-legal aspects of health care is essential. Professionals must be aware of the fundamental aspects of medical professional liability, as well as specific aspects, such as defensive medicine and clinical safety. The understanding of these medical-legal aspects in the routine clinical practice can help to pave the way towards a satisfactory and safe professional career, and help in increasing patient safety. The aim of this review is to contribute to this training, for the benefit of professionals and patients. Copyright © 2017 Sociedad Española de Oftalmología. Publicado por Elsevier España, S.L.U.

  20. The foundation of experimental ophthalmology by Theodor Leber.

    PubMed

    Jaeger, W

    1988-01-01

    Theodor Leber grew up in Heidelberg as the son of a professor of Romance languages. Initially he planned to study natural sciences. Bunsen's advice led him to medicine. During his studies he succeeded in solving a competition problem posed by Helmholtz in the medical department. A short period of practical work in the eye hospital of Knapp was unsatisfactory. In Vienna with the physiologist Carl Ludwig, he was able in 1863/64, at the age of only 24 years, to demonstrate the blood circulation of the eye by color injections into the arteries and veins. Since that time the schematic drawings of his results can be found in every textbook of ophthalmology. On the occasion of the congress of the German Ophthalmological Society in Heidelberg in 1864, Theodor Leber reported on these findings and met with immense approval. In 1864-67 he followed an invitation as coworker of Liebreich to Paris; in 1867 he became A.v. Graefe's coworker in Berlin; in 1871 he moved to Göttingen, which became the first eye clinic with a laboratory for experimental investigations. The second epoch-making discovery accomplished by Leber was the detection of the fluid exchange in the eye. These results have also been confirmed by modern methods. Therefore, Theodor Leber can be called the father of experimental ophthalmology.

  1. The human resource crisis in neuro-ophthalmology.

    PubMed

    Frohman, Larry P

    2008-09-01

    Neuro-ophthalmology is facing a serious human resource issue. Few are entering the subspecialty, which is perceived as being poorly compensated compared with other subspecialties of ophthalmology. The low compensation comes from the fact that 1) non-procedural encounters remain undervalued, 2) efforts that benefit other medical specialists are not counted, and 3) the relatively low expenses of neuro-ophthalmologists are not factored into compensation formulas. Mission-based budgeting, which forces academic departments to be financially accountable without the expectation of fiscal relief from medical schools or practice plans, has exacerbated the compensation issue. Solutions must come from within neuro-ophthalmology, academic departments, medical schools, and medical practice plans. They include 1) providing educational resources so that neuro-ophthalmologists need not spend so much time teaching the basics, 2) factoring into compensation the impact of neuro-ophthalmologists in teaching and on revenue generation by procedure-based specialists, 3) improving the efficiency of neuro-ophthalmologists in their consultative practices by providing ample clerical support and other measures, 4) providing contractual salary compensation by departments such as neurosurgery to recognize the contributions made by neuro-ophthalmologists, and 5) reorganizing the academic clinical effort as multidisciplinary rather than departmental.

  2. Quasi-Elastic Light Scattering in Ophthalmology

    NASA Astrophysics Data System (ADS)

    Ansari, Rafat R.

    The eye is not just a "window to the soul"; it can also be a "window to the human body." The eye is built like a camera. Light which travels from the cornea to the retina traverses through tissues that are representative of nearly every tissue type and fluid type in the human body. Therefore, it is possible to diagnose ocular and systemic diseases through the eye. Quasi-elastic light scattering (QELS) also known as dynamic light scattering (DLS) is a laboratory technique routinely used in the characterization of macromolecular dispersions. QELS instrumentation has now become more compact, sensitive, flexible, and easy to use. These developments have made QELS/DLS an important tool in ophthalmic research where disease can be detected early and noninvasively before the clinical symptoms appear.

    The advances in gene therapy hold significant promise for the treatment of ophthalmic conditions. Several studies using animal models have been published. Animal models on retinitis pigmentosa, Leber’s Congenital Amaurosis (LCA), and Stargardt disease have involved the use of adeno-associated virus (AAV) to deliver functional genes into mice and canines. Mice models have been used to show that a mutation in cGMP phosphodiesterase that results in retinitis pigmentosa can be corrected using rAAV vectors. Additionally, rAAV vectors have been successfully used to deliver ribozyme into mice with a subsequent improvement in autosomal dominant retinitis pigmentosa. By using dog models, researchers have made progress in studying X-linked retinitis pigmentosa which results from a RPGR gene mutation. Mouse and canine models have also been used in the study of LCA. The widely studied form of LCA is LCA2, resulting from a mutation in the gene RPE65. Mice and canines that were injected with normal copies of RPE65 gene showed signs such as improved retinal pigment epithelium transduction, visual acuity, and functional recovery. Studies on Stargardt disease have shown that mutations in the ABCA4 gene can be corrected with AAV vectors, or nanoparticles. Gene therapy for the treatment of red–green color blindness was successful in squirrel monkeys. Plans are at an advanced stage to begin clinical trials. Researchers have also proved that CD59 can be used with AMD. Gene therapy is also able to treat primary open angle glaucoma (POAG) in animal models, and studies show it is economically viable.

    The growing importance that mobile devices have in daily life has also reached health care and medicine. This is making the paradigm of health care change and the concept of mHealth or mobile health more relevant, whose main essence is the apps. This new reality makes it possible for doctors who are not specialist to have easy access to all the information generated in different corners of the world, making them potential keepers of that knowledge. However, the new daily information exceeds the limits of the human intellect, making Decision Support Systems (DSS) necessary for helping doctors to diagnose diseases and also help them to decide the attitude that has to be taken towards these diagnoses. These could improve the health care in remote areas and developing countries. All of this is even more important in diseases that are more prevalent in primary care and that directly affect the people's quality of life, this is the case in ophthalmological problems where in first patient care a specialist in ophthalmology is not involved. The goal of this paper is to analyse the state of the art of DSS in Ophthalmology. Many of them focused on diseases affecting the eye's posterior pole. For achieving the main purpose of this research work, a literature review and commercial apps analysis will be done. The used databases and systems will be IEEE Xplore, Web of Science (WoS), Scopus, and PubMed. The search is limited to articles published from 2000 until now. Later, different Mobile Decision Support System (MDSS) in Ophthalmology will be analyzed in the virtual stores for Android and iOS. 37 articles were selected according their thematic (posterior pole, anterior pole, Electronic Health Records (EHRs), cloud, data mining, algorithms and structures for DSS, and other) from a total of 600 found in the above cited databases. Very few mobile apps were found in the different stores. It can be concluded that almost all existing mobile apps are focused on the eye's posterior

    The excitation energy and angular momentum dependence of the entry states in fusion reactions measured with the spin spectrometer is discussed. A new decay mode involving the onset of localized stretched dipole radiation at half the accompanying stretched E2 collective radiation is found in /sup 157 -161/Yb. The appearance of this mode correlates smoothly with neutron number and spin. Possible interpretations are presented in terms of the evolution of the nuclear shapes from prolate to aligned-quasiparticle oblate to collective oblate and then to triaxial. Evidence for nuclear deformation that increases with spin at very high excitation is presented based on ..cap alpha..-particle angular distributions measured relative to the spin direction, using a new method for deriving the spin alignment.

    1996-08-01

    The American Academy of Ophthalmology and Otolaryngology grew steadily during its 82-year existence, and since 1979, the American Academy of Ophthalmology has had an accelerated increase in membership and activity. In 1995, as the Academy approached its centennial, the AAO had more than 20,000 members and an annual budget of more than +26 million. Total registration for the 1994 Annual meeting was slightly more than 27,000, an all-time high. Instruction Courses numbered 450,300 scientific papers were presented, and 130 posters were displayed. The original postgraduate course in 1921 served as the predecessor to the more than 700 hours of instruction presented at the 1994 Annual Meeting. The original committee of four was the predecessor of what has become the Secretariats of the Academy. The popular Home Study Courses were the forerunners of the Academy's programs, formulated and supervised by the Education Secretaries. The Clinical Education Programs include the Basic and Clinical Science Courses, Focal Points, Continuing Ophthalmic Video Education, Manuels, Regional Update Courses, Special Focus/Skills Courses, Monographs, PROvision, slide scripts, and other programs produced for allied health personnel, medical students, and other physicians. The Secretaries originate, produce, and oversee all the important functions of the Academy. The individuals who have served the Academy as Secretaries through the years have been dedicated volunteers. Their contributions have been incalculable. In recent years, the various Secretaries have been ably assisted by Associate Secretaries, Advisory Committees, and Subcommittees, spreading the workload of each Secretary. Credit for the success of the Academy's endeavors, while under the guidance of the Secretaries, also must be given to the Academy's many committee chairs and committee members who have diligently worked to achieve their goals and objectives.

    The objective of this article was an analytical review of reading charts with regard to the historical background, printing techniques, print quality and print size. For this study original historical reading charts (Jaeger, Snellen, Nieden and Birkhäuser) were investigated microscopically by measuring the lower case letter sizes (iNexis VMA 2520, Nikon, Tokyo). Calculations were made according to EN ISO 8596 and the recommendations of the International Research Council. In the mid-nineteenth century various reading cards were published; however, at that time it was not possible to print lower case letters according to exactly defined standards. Thus, these reading cards were not comparable to each other or between different language versions. At a reading distance of 32 cm Jaeger No. 1 represented in the original edition (1856) a visual acuity of 0.72 and 0.63 in the version from 1945 and the smallest print size of the Snellen reading test (1862) represented 0.55. Nieden No. 1 (1882) corresponded to a visual acuity of 0.59 and the smallest print size of the Birkhäuser cards (1911) 1.5. In the case of all reading cards except the original Birkhäuser cards, there was no logarithmic progression of the print sizes and the sizes of numbers were also not in accordance with the corresponding letter sizes. Print sizes of historical reading charts do not adhere to current standards and were usually not logarithmically scaled. These deficits and the lack of comparability between the historical reading charts may have caused reading cards to be currently underestimated as an accurate diagnostic tool. Nevertheless, the historical reading charts were the successful forerunners of developments for modern reading charts.

    2014-06-01

    The quality of general practitioner (GP) ophthalmology referrals to emergency departments has been reported to be sub-optimal. It is possible that a lack of adequate formal training in ophthalmology for GPs contributes to this situation. Data in this study was obtained from a postal survey of GPs to ascertain their knowledge of, and confidence with, clinical ophthalmology skills as well as their training in this speciality. Undergraduate ophthalmology training was rated as inadequate by 35/50 (70%) respondents. 28 (56%) respondents reported to be confident with their clinical ophthalmology skills. 19 (38%) GPs reported to have good knowledge of ophthalmology, and this was strongly associated with a positive appraisal of their undergraduate ophthalmology training (92%, P < 0.01), having experience working in an ophthalmology department (80%, p = 0.14) and having received GP training abroad (52%, p = 0.16). Regarding ophthalmology equipment, 47 (94%) GPs reported to have an ophthalmoscope but only 33 (66%) were confident with its use and just 20 (40%) could confidently distinguish an abnormal optic disc. Lack of knowledge of ophthalmology may have a significant impact on patient care and could be addressed by including clinical skills training in GP specialist training or continuing professional development schemes.

METHODS A closed-ended questionnaire was circulated to all ophthalmologists who completed their training in Jordanian institutions between 2006 and 2011, to measure the quality of residency training and satisfaction level with regards to clinical conferences, journal clubs, scientific lectures, wet lab sessions, simulations, outpatient clinics and operating room training. Barriers to a successful board exam were cited. All ophthalmologists had official residency training in Jordanian Hospitals; this includes military, university, governmental and private sector hospitals. RESULTS Sixty-one questionnaires completed out of 69 circulated. Males (75.4%) were more than females. Mean age was 32.5±3.27y. A total 21 (34.4%) responders expressed an overall satisfaction, 38 (62.3%) were dissatisfied and 2 (3.3%) were equivocal. Respondents reported insufficient exposure to low-vision rehabilitation 57 (93.4%), or refraction and glasses prescription 34 (55.7%). Regarding operative experiences, the mean cataract extraction per-resident was 43 cataracts; the number of phacoemulsification surgery was 2.96 per-resident, 46 (75.4%) of responders never did a single phacoemulsification during residency. Nine (14.8%) had training in refractive surgery, and 15 (24.6%) assisted orbital surgery. Forty-four (72.1%) never assisted in vitreoretinal surgery. Among The graduates surveyed, 14 (23.0%) passed Jordanian licensing board exam at the first attempt, and felt that their residency programs adequately prepared them for the examinations. CONCLUSION Around two thirds (62.3%) of ophthalmologists expressed dissatisfaction with residency training at Jordanian programs, further study is required to assess

    Ophthalmic medical student education is a cornerstone to improving eye health care globally. We review the current state of the literature, listing barriers to potential best practices for undergraduate ophthalmology teaching and learning within medical curricula. We describe recent advances and pedagogical approaches in ophthalmic education and propose specific recommendations for further improvements and research. Future research should concentrate on developing teaching and learning innovations that may result in a more time- and resource-effective models for interactive and integrated learning. As well as demonstrating that a competency-based approach results not just in better eye health, but also improvements in patient care, education, and medical care in general. By optimizing teaching available through improved evidence-based education, the ultimate goal is to increase medical students' knowledge and produce graduates who are highly trained in eye examination skills, resulting in improved patient eye care through timely diagnosis, referrals, and treatment.

    Many have observed what appears to be declining interest on the part of ophthalmology graduates in pediatric ophthalmology and strabismus (PO&S) as a career. Four questions might address this concern: (1) Has there been a decline in the number of fellowship positions filled in the period 2000 to 2005? (2) Why do graduates choose other career paths? (3) Assuming there has been a decrease in interest in PO&S, does it reflect dissatisfaction on the part of pediatric ophthalmologists in their field? (4) What can be done to enhance the appeal of the subspecialty? Data from the San Francisco Matching Programs covering the years 2000 through 2005 included the numbers of ophthalmology graduates, their subspecialty choices, the number of applicants to PO&S and other subspecialty fellowships, and the number of fellowship positions offered. Supplemental surveys assessed positions filled outside the match and international fellows. Factors influencing residents' career choices and the job satisfaction of pediatric ophthalmologists were analyzed in separate surveys. The number of fellowship positions in PO&S increased from 41 to 50 between 2000 and 2004. The number of graduates participating in the match has varied but remained the same (38) in 2005 as in 2000. Graduates were discouraged from PO&S by inadequate mentoring, by aversion to children, and by higher compensation in other fields. Pediatric ophthalmologists generally are highly satisfied in their careers, although financial compensation is a concern for many. Pediatric ophthalmologists should remain optimistic about recruitment but could enhance the appeal of PO&S by teaching more effectively and by promoting the field.

    Patients increasingly consult online resources for healthcare information. The American Medical Association (AMA) and National Institutes of Health (NIH) recommend that online education resources be written between a 3rd- and 7th-grade level. This study assesses whether online health information abides by these guidelines. Ten pediatric ophthalmology conditions were entered into a commonly used search engine, Google.com, and analyzed using 10 validated readability scales. Scientific articles and articles written on patient forums were excluded. The 10 conditions--amblyopia, cataract, conjunctivitis, corneal abrasion, nystagmus, retinoblastoma, retinopathy of prematurity, strabismus, stye, and glaucoma--were also searched and analyzed separately from widely used websites, including Wikipedia and WebMD, as well as those of professional societies, including the American Association for Pediatric Ophthalmology and Strabismus (AAPOS) and the American Optometric Association (AOA). The majority of articles were written above recommended guidelines. All scales showed that the 100 articles were written at a mean grade-level of 11.75 ± 2.72. Only 12% of articles were written below a 9th-grade level and only 3% met recommended criteria. The articles accrued separately from Wikipedia, WebMD, AAPOS, and AOA also had average grade levels above the recommended guidelines. The readability of online patient education material exceeds NIH and AMA guidelines. This disparity can adversely affect caregiver comprehension of such resources and contribute to poor decision making. Pediatric ophthalmology online articles are generally written at a level too high for average caregiver comprehension. Revision of articles can increase satisfaction, improve outcomes, and facilitate the patient-ophthalmologist relationship. Published by Elsevier Inc.

    The purpose of this study was to determine if patients and their families in a pediatric ophthalmology and adult strabismus clinic have a preference regarding physician and staffattire. Patients and/or parents were invited to complete a three-question survey. Respondents were queried based on three types of attire preference: white coat, professional clothing without white coat, or casual attire without white coat. Two hundred twenty-seven patients participated. Of the patients queried, no preference for any one style of physician attire was found. These results do not support previous studies indicating significant preference for white coats.

    Lipoid proteinosis (LP) is an uncommon, recessively inherited disorder. The disease usually has its onset in the newborn period and is manifested by hoarseness. The skin and mucous membrane involvement arises between the first and second year of age. A 14-year-old male presented with the complaint of blistering on various sites of his skin, from the age of 12 months, resulting in scarring. Ophthalmological and psychiatric findings also appeared during the clinical course. The histological findings of skin biopsy included extensive deposits of amorphous eosinophilic material in the papillary dermis. No known therapy exists for LP.

    Most pathological processes involve complex molecular pathways that can only be modified or blocked by a combination of medications. Combination therapy has become a common practice in medicine. In ophthalmology, this approach has been used effectively to treat bacterial, fungal, proliferative/neoplastic, and inflammatory eye diseases and vascular proliferation. Combination therapy also encompasses the synergistic effect of electromagnetic radiation and medications. However, combination therapy can augment inherent complications of individual interventions, therefore vigilance is required. Complications of combination therapy include potential incompatibility among compounds and tissue toxicity. Understanding these effects will assist the ophthalmologist in his decision to maximize the benefits of combination therapy while avoiding an unfavorable outcome.

    Almost all soldiers of the armies involved in the Egyptian campaign fell victim to what was later called the ophthalmia militaris which we now know to be caused by Haemophilus aegyptius, N. gonorrhoea and possibly to some extent by Chlamydia trachomatis but more likely by the adenoviruses. Because of the enormous incidence of ocular infection and the controversy generated by speculation on the nature of the disease--English surgeons considered this ophthalmia to be of a contagious nature, whereas the French surgeons violently opposed this view-, the interest in diseases of the eye increased, which eventually resulted in the acceptance of ophthalmology as a separate branch of medicine.

    To evaluate quantitative and qualitative differences in documentation of the ophthalmic examination between paper and electronic health record (EHR) systems. Comparative case series. One hundred fifty consecutive pairs of matched paper and EHR notes, documented by 3 attending ophthalmologist providers. An academic ophthalmology department implemented an EHR system in 2006. Database queries were performed to identify cases in which the same problems were documented by the same provider on different dates, using paper versus EHR methods. This was done for 50 consecutive pairs of examinations in 3 different diseases: age-related macular degeneration (AMD), glaucoma, and pigmented choroidal lesions (PCLs). Quantitative measures were used to compare completeness of documenting the complete ophthalmologic examination, as well as disease-specific critical findings using paper versus an EHR system. Qualitative differences in paper versus EHR documentation were illustrated by selecting representative paired examples. (1) Documentation score, defined as the number of examination elements recorded for the slit-lamp examination, fundus examination, and complete ophthalmologic examination and for critical clinical findings for each disease. (2) Paired comparison of qualitative differences in paper versus EHR documentation. For all 3 diseases (AMD, glaucoma, PCL), the number of complete examination findings recorded was significantly lower with paper than the EHR system (P ≤ 0.004). Among the 3 individual examination sections (general, slit lamp, fundus) for the 3 diseases, 5 of the 9 possible combinations had significantly lower mean documentation scores with paper than EHR notes. For 2 of the 3 diseases, the number of critical clinical findings recorded was significantly lower using paper versus EHR notes (P ≤ 0.022). All (150/150) paper notes relied on graphical representations using annotated hand-drawn sketches, whereas no (0/150) EHR notes contained drawings. Instead

    Resident physicians have reported spending upward of 25% of their time teaching fellow residents and medical students. Until relatively recently, there have not been formal requirements in residency programs to learn teaching skills. The first goal of this study was to develop a novel residents-as-teachers training program to educate Ophthalmology residents on facilitating group learning and emphasizing critical-thinking skills. The second goal was to educate residents on how to teach clinical reasoning skills. We designed a longitudinal residents-as-teachers program that consisted of a 2-hour workshop, voluntary observation of their teaching in the small group, and student feedback on their teaching. The focus of the workshop was to educate the residents on how to facilitate critical thinking and clinical reasoning in a small group format. Voluntary video recording of residents' teaching was offered, and feedback on their teaching was provided. Yale University School of Medicine, Department of Ophthalmology and Visual Science. In total, ten second-year medical student groups consisting of approximately 7 to 11 students in each group were organized in this course and each group had one teacher: 4 senior Ophthalmology residents and 6 community faculty. This study found that the resident teachers who completed the residents-as-teachers program were equally as effective as community faculty teachers in building medical students' comprehension of ophthalmic principles during small group seminars according to the students' evaluation of teaching performance. We also found that all of the medical students' responses were overwhelmingly positive toward having residents as teachers. The medical students particularly noted residents' preparedness and effectiveness in facilitating a discussion during the small group seminars. Our novel program was effective at teaching residents how to teach critical-thinking skills and the resident teachers were well received by medical

    The usage of the Internet in live-broadcasting ophthalmological lectures might be helpful in the education of eye doctors. The purpose is to report first experiences of a live-broadcasted congress. The congress "Autonomic Innervation and Microcirculation of the Eye--Implications in Glaucoma Pathophysiology", held in the Department of Ophthalmology of the University Erlangen-Nürnberg at the 27th January 1999 was live-broadcasted via Internet by the electronic journal "Online Journal of Ophthalmology" (www.onjoph.com). The congress was organized by the "Sonderforschungsbereich 539, Glaukome, einschliesslich PEX" of the University Erlangen-Nürnberg. The original sound of the lectures was digitized by 8000 Hz and coded with 14 bit. Using the free software "Real-Audio-Player" the user could hear the speech of the lecturer in radio quality. Two live-pictures from two digital video cameras and the digitized slides were available at the screen within two frames. Two weeks before all 6576 ophthalmologists in Germany were informed about the event by conventional mail. The live-broadcasted congress was followed by 899 online-participants (899/6576 = 13.6%). 238 of 899 participants were able to hear the original sound. 154 of 6576 (2.3%) ophthalmologists answered by FAX. 18% of the answering eye doctors have followed the congress by Internet. Mainly all (98%) of them were very interested in live-broadcasted lectures or congresses and wanted to be informed about the next lecture or congress broadcasted by means of Internet. The lectures-on demand of this congress with sound and pictures are now available under the address http:/(/)www.onjoph. com/global/livewrk1/Default.htm. The major part of eye doctors in Germany seems very interested in live-broadcasted lectures for online-education. In the first national-wide trial 899 of 6576 informed eye doctors followed the congress.

    The Gamma Knife was designed by Lars Leksell in the early 1950's. It gave rise to a new discipline of medicine--stereotactic radiosurgery. Primarily dedicated to neurosurgery, the Gamma Knife has become an alternative, widely used surgery technique. According to Elekta's statistics, approximately 60,000 people are treated with Leksell Gamma Knife every year and it is the most extensively studied stereotactic radiosurgery system in the world. The Leksell Gamma Knife can also be used in ophthalmology. The gamma ray beam concentration enables effective treatment of uveal melanoma, choroidal hemangioma, orbital tumors or even choroidal neovascularization. The virtue of Leksell Gamma Knife is its extreme precision, non-invasiveness and the possibility of outpatient treatment, which significantly reduces costs and diminishes post-operative complications. Innovative solutions shorten a single session to a minimum, which is very comfortable and safe for both staff and patients. Advantages and possible side effects of gamma knife radiosurgery are well-documented in the professional literature. The objective of this review is to present the recognized applications of Leksell Gamma Knife in ophthalmology.

    There has been a shift in graduate medical education (GME) from the traditional “apprenticeship” model to a more curriculum-based and competency driven model. Reflecting a global trend towards residency education reform, the International Council of Ophthalmology (ICO) introduced a resident and specialist curriculum and several live educational programs to promote standardization and more effective GME and continuing professional training. Implementation of these educational innovations will require efforts by local educator champions; modification and customization of teaching and assessing tools to the local learning environment; alignment of the implementation blueprint with available resources; and creation of accountability and sustainability mechanisms to insure long-term viability of the educational reforms. An ultimate goal of the ICO curriculum is to allow real world testing and modification so that the ideas generated in one part of the world might be applicable and generalizable in other areas. We aim to describe the Accreditation Council of Graduate Medical Education (ACGME) competencies in the United States (US) and ICO curriculum, as well as to provide a step-by-step plan for implementation of an ophthalmology residency curriculum.

    A stereoscopic imaging modality was developed for the application of ophthalmology surgical microscopes. A previous study has already introduced a single-channel stereoscopic video imaging modality based on a transparent rotating deflector (SSVIM-TRD), in which two different view angles, image disparity, are generated by imaging through a transparent rotating deflector (TRD) mounted on a stepping motor and is placed in a lens system. In this case, the image disparity is a function of the refractive index and the rotation angle of TRD. Real-time single-channel stereoscopic ophthalmology microscope (SSOM) based on the TRD is improved by real-time controlling and programming, imaging speed, and illumination method. Image quality assessments were performed to investigate images quality and stability during the TRD operation. Results presented little significant difference in image quality in terms of stability of structural similarity (SSIM). A subjective analysis was performed with 15 blinded observers to evaluate the depth perception improvement and presented significant improvement in the depth perception capability. Along with all evaluation results, preliminary results of rabbit eye imaging presented that the SSOM could be utilized as an ophthalmic operating microscopes to overcome some of the limitations of conventional ones.

    2011-01-01

    Simulation can be defined as malingering, or sometimes functional visual loss (FVL). It manifests as either simulating an ophthalmic disease (positive simulation), or denial of ophthalmic disease (negative simulation). Conscious behavior and compensation or indemnity claims are prominent features of simulation. Since some authors suggest that this is a manifestation of underlying psychopathology, even conversion is included in this context. In today's world, every ophthalmologist can face with simulation of ophthalmic disease or disorder. In case of simulation suspect, the physician's responsibility is to prove the simulation considering the disease/disorder first, and simulation as an exclusion. In simulation examinations, the physician should be firm and smart to select appropriate test(s) to convince not only the subject, but also the judge in case of indemnity or compensation trials. Almost all ophthalmic sensory and motor functions including visual acuity, visual field, color vision and night vision can be the subject of simulation. Examiner must be skillful in selecting the most appropriate test. Apart from those in the literature, we included all kinds of simulation in ophthalmology. In addition, simulation examination techniques, such as, use of OCT (optical coherence tomography), frequency doubling perimetry (FDP), and modified polarization tests were also included. In this review, we made a thorough literature search, and added our experiences to give the readers up-to-date information on malingering or simulation in ophthalmology. PMID:22553721

    Purpose The purpose of this study was to improve communication between the ophthalmology and histopathology departments at Royal Hallamshire Hospital, Sheffield, by effectively changing the structure and completion of the histopathology request form through the process of a successful audit. This aimed to ensure that comprehensive information was made available to the histopathologist. Methods An audit was performed by review of 710 histopathology request forms, completed by the ophthalmology department, over a 1-year period, between July 2005 and June 2006 inclusive. Results were used to re-model the ophthalmic histopathology request form. New forms were circulated and all forms completed over a 3-month period, between January 2008 and March 2008, were reviewed, thus closing the audit loop. Results On the basis of audit results of 710 histopathology request forms, a new histopathology request form was created, which was easier to complete. Review of the 224 new histopathology request forms showed improved percentages of completion of important sections of the form. Conclusions Through the audit process we have created a new ophthalmic histopathology request form that is more user-friendly for the ophthalmologist and more consistently provides the necessary information for the ophthalmic histopathologist. This has improved efficiency and effectiveness of communication between the specialities, which should contribute to minimise the chances of medical error and improved turnaround times for the planning and delivery of patient care.

    Since the first publication of the Chinese Journal of Ophthalmology on October 1st, 1950, following the establishment of the People's Republic of China, more than fifty years have already elapsed. The editors and publishers of the elder generation of this magazine have witnessed the hardships in starting publication, the disappointments of the discontinuation of publication during certain periods, as well as the great delight of restarting publication. Having entered the 21st century, editors and publishers of the new generation have made dramatic achievements by keeping up with the times and continuously seeking innovations. However all of these achievements have only turned out to be the past. There are even more challenges for moving ahead in the future. The Chinese Journal of Ophthalmology has noted its achievements on the one hand; while on the other hand, has analyzed the main existing problems of this magazine. Some feasible approaches to improve the magazine have been proposed and the direction in the following few years was ascertained. We will collaborate with Chinese ophthalmologists to work towards the continuous development of this magazine.

    To determine the relationship between eye drop use and contamination rate in ophthalmology offices. Following permission request, open bottles were examined and the nozzle tip and one drop of content was cultured on solid media. Drug category, volume, weight compared to full, clean legible label, expiration date; 2 or more bacterial colonies along the inoculation site. In 18 offices, of 1,485 open bottles (mean 12.2, range 4 to 23 per lane) on average 19.8% (range 0% to 88%) were expired (16.2 of 82.5 bottles per office). The frequency of occurrence (%) and expiration (%E) were 40.3% cycloplegics (19.4%E); 16.4% glaucoma (33.7%E); 10.8% anesthetics (8.8%E); and 4% steroids (8.8%E; or 42.2%E including one outlier). Most likely expired were glaucoma (P < 0.001); small 2-3 ml (P < 0.02), nearly empty (P < 0.05), or dirty (P < 0.001) bottles. Only one (5 ml cyclopentolate, not expired) grew a Micrococcus (0.07%). Drops in ophthalmology offices may be expired but are not contaminated.

    Purpose Laplace's Law, with its compactness and simplicity, has long been employed in ophthalmology for describing the mechanics of the corneoscleral shell. We questioned the appropriateness of Laplace's Law for computing wall stress in the eye considering the advances in knowledge of ocular biomechanics. Methods In this manuscript we recapitulate the formulation of Laplace's Law, as well as common interpretations and uses in ophthalmology. Using numerical modeling, we study how Laplace's Law cannot account for important characteristics of the eye, such as variations in globe shape and size or tissue thickness, anisotropy, viscoelasticity, or that the eye is a living, dynamic organ. Results We show that accounting for various geometrical and material factors, excluded from Laplace's Law, can alter estimates of corneoscleral wall stress as much as 456% and, therefore, that Laplace's Law is unreliable. Conclusions We conclude by illustrating how computational techniques, such as finite element modeling, can account for the factors mentioned above, and are thus more suitable tools to provide quantitative characterization of corneoscleral biomechanics.
