摘要： A 62-year-old woman presented to our clinic in April 2021 with a painful right eye and increased light sensitivity for 1 week, 30 years after laser in situ keratomileusis (LASIK) in both eyes for myopia of similar to 2.5 diopters. There were no complaints of the left eye. There were no abnormalities in her medical history. The uncorrected distance visual acuity (UDVA) of the right eye at presentation was 20/20. Slitlamp biomicroscopy revealed epithelial ingrowth on the right eye with stromal edema and inflammation and fine keratic precipitates on the endothelium (Figures 1 and 2). The cornea of the left eye was unremarkable. The anterior chamber of the right eye showed 1 + cells (SUN grading). There were no abnormalities in the posterior segment. Figure 3 shows the corneal epithelial ingrowth with a swept-source optical coherence tomography (OCT) and Figure 4 an axial corneal Scheimpflug tomography map. What is your treatment advice for this patient from a short- and long-term perspective? (C) 2021 Published by Wolters Kluwer on behalf of ASCRS and ESCRS

摘要： Background: Low back pain (LBP) is expected to globally affect up to 80% of individuals at some point during their lifetime. While conventional LBP therapies are effective, they may result in adverse side-effects. It is thus common for patients to seek information about complementary and alternative medicine (CAM) online to either supplement or even replace their conventional LBP care. The present study sought to assess the quality of web-based consumer health information available at the intersection of LBP and CAM. Methods: We searched Google using six unique search terms across four English-speaking countries. Eligi-ble websites contained consumer health information in the context of CAM for LBP. We used the DISCERN instrument, which consists of a standardized scoring system with a Likert scale from one to five across 16 questions, to conduct a quality assessment of websites. Results: Across 480 websites identified, 32 were deemed eligible and assessed using the DISCERN instru-ment. The mean overall rating across all websites 3.47 (SD = 0.70);Summed DISCERN scores across all websites ranged from 25.5-68.0, with a mean of 53.25 (SD = 10.41);the mean overall rating across all websites 3.47 (SD = 0.70). Most websites reported the benefits of numerous CAM treatment options and provided relevant information for the target audience clearly, but did not adequately report the risks or adverse side-effects adequately. Conclusion: Despite some high-quality resources identified, our findings highlight the varying quality of consumer health information available online at the intersection of LBP and CAM. Healthcare providers should be involved in the guidance of patients' online information-seeking. (c) 2021 Published by Elsevier B.V. on behalf of Korea Institute of Oriental Medicine.

摘要： Returning to Manne et al. (2000), wherein a class of hyperbolic reaction-diffusion-acoustic models is considered, we show that the inexact transport equation derived by these authors becomes the exact equation for the propagation of second-sound (i.e., thermal waves) in a rigid solid when reformulated under the modified internal energy model, one of several formulations of what has come to be known as hyperbolic heat conduction theory. We then compare/contrast this PDE with/to its exact version, which is based on Cattaneo's equation for the thermal flux, in the context of a signaling problem involving weak discontinuities of second-sound propagating in a solid rod. Our analysis also reveals a connection between the modified internal energy model and what has been termed "inertial theory'', a competing theory of second-sound in solids, and suggests a generalization of the quantity known as the "thermasy''. We conclude with a discussion on the application of the present findings to a well known, widely applicable, class of nonlinear wave equations. Published by Elsevier B.V.
