Pain perception using a computer-controlled anaesthetic delivery system in paediatric dentistry: A review.

In paediatric dentistry it is essentials to reduce axiety and fear induced by local anaesthetic injection, in order to obtain patient's cooperation and achieve a successful treatment. Hence, this review is aiming to primary evaluate pain perception in paediatric patients when using a computer-controlled local anaesthetic delivery system (C-CLADS) compared to traditional injection. A database literature search was conducted on both MEDLINE and Cochrane Central Register of Controlled Trials and a data extraction table was created to perform a critical evaluation of each scientific article. The primary results were the perception of pain during anaesthesia and the patient's behaviour, the secondary the amount of anaesthetic required and its duration over time. In the review were included 7 clinical studies regarding paediatric patients where split-mouth designs or group division were used. The age range was between 5 and 17 years old. Pain and fear parameters were measured by visual analogue scales, behavioural scales, heart rate and satisfaction questionnaires. Substantial heterogeneity between clinical trials was observed, which led to difficult comparison. Computerised devices have proved to be interesting in reducing pain during anaesthesia, improving the approach to the paediatric patient. It is advisable to conduct research with anxious subjects and patients under the age of 4, because no evidence has been found in the literature. It is recommended to conduct further research with anxious subjects and patients below the age of 4, where Relative Analgesia by Langa or pharmacological anxiolysis are frequently used.

Comparison of the clinical efficacy of AcrySof® IQ and TECNIS® toric intraocular lenses: A real-world study.

Corneal astigmatism significantly compromises uncorrected visual acuity (UCVA) after phacoemulsification with implantation of traditional spherical or non-spherical monofocal intraocular lens (IOL). Toric IOL provides an effective way to gain favorable postoperative UCVA for the patients with cataracts with corneal astigmatism. There are numerous types of toric IOLs; however AcrySof® IQ toric IOL (Alcon Laboratories, Inc.) and TECNIS® toric IOL (Johnson & Johnson Vision; Johnson & Johnson) are most frequently used in our clinical practice. The purpose of the current study was to compare the clinical efficacy of AcrySof IQ with TECNIS toric IOL implantation, and to provide a clinical basis on selecting an appropriate toric IOL before cataract surgery for patients with corneal astigmatism. A total of 30 patients with cataract (44 eyes) with corneal astigmatism [0.82-7.27 diopters (D)], who have undergone phacoemulsification with toric IOL implantation between October 2012 and December 2017, were included in the current retrospective cohort study. Patients were divided into two groups: One group (26 eyes) received the AcrySof IQ toric IOL (AcrySof group) and the other group (18 eyes) received the TECNIS toric IOL (Tecnis group). The indexes of curative effect, such as uncorrected and corrected distance visual acuity (UDVA and CDVA, respectively), refractive outcomes, contrast sensitivity (CS), IOL rotation, and satisfaction, were evaluated. Both toric IOLs significantly improved UDVA and CDVA. Postoperative mean residual astigmatism was similar in the AcrySof group and in the Tecnis group (0.75±0.50 and 0.78±0.90 D; P=0.896). There was no statistically significant between postoperative CS in the AcrySof and Tecnis groups. Rotations of >10˚ were considered to be significant and were identified in three eyes. The mean IOL rotation showed no statistically significant difference (AcrySof group, 0.24±5.54˚; Tecnis group, -0.19±6.28˚; P=0.416). The mean patient satisfaction score was 8.46±1.21 in the AcrySof group and 8.78±1.44 in the Tecnis group (P=0.260). The results of the current study indicated that patients with cataracts with corneal astigmatism undergoing phacoemulsification with AcrySof IQ and TECNIS toric IOL implantation achieved similar clinical efficacy in term of visual outcomes, refraction correction, CS, rotational stability and satisfaction.

Evaluation of the effect of landscape distance seen in window views on visual satisfaction

Daylighting standards dictate that the view seen through a window can be evaluated using several criteria. Among one of them is the distance at which the visual content can be seen. However, not enough guidance is given on how this criterion can be applied in practice. We used two approaches to address this problem: online surveys and human subject assessment in a controlled experiment using an artificial window. Images were used in both cases to represent window views. Two independent groups of participants took part in either study and both gave subjective satisfaction ratings to three parameters, namely, connection to the outside, visual content and visual privacy. Eighteen images were evaluated in the online surveys by a total of 91 participants while eight images were rated by 50 participants that took part in the controlled experiment. We developed a calculation method, named the Observer Landscape Distance (OLD), to quantify the distance of the window view landscape from the occupant. Our initial results showed that people are more satisfied when features are far away. However, we also showed that when the landscape contained nature, the effect of distance was smaller. If far away views cannot be provided due to site constrains, nature (e.g. trees) should be integrated nearby to increase satisfaction. Current daylighting standards promote distant views regardless of its visual content (nature or urban). We found that visual content matters and occupants prefer urban features to be viewed from a distance, whereas this same recommendation does not apply for nature.

Syncing with the Sky: Daylight-Driven Circadian Lighting Design

ABSTRACT The use of daylight in the built environment is often preferred to artificial light sources as its successful application can provide visual comfort and satisfaction along with the potential for significant energy savings. Exposure to daylight is also the primary source for stimulus that establishes a healthy day/night cycle in all living organisms. This is known as circadian rhythm. Newly discovered photoreceptors (intrinsically photosensitive retinal ganglion cells – ipRGC) within the mammalian eye, including humans, are specifically linked to the portion of the brain responsible for maintaining a healthy circadian rhythm. This discovery has led to a new subject area in the field of lighting design focused on controlling the spectrum of light that these photoreceptors are sensitive to. Currently, work in the field of circadian lighting design is concentrated on the use of artificial light sources for circadian stimulus. This is largely due to the advent of the widespread use of LED technology, which has proven that it can be a significant source of light that can delay or advance the circadian clock. The use of daylight to provide circadian stimulus has been a given in this field of design, however, there has not been very much research into how the built environment affects our ability to effectively receive this stimulus from daylight. In this research, the groundwork is established to start to create a set of guidelines to help architects and designers maximize the potential for daylight to provide circadian stimulus at the earliest stages of a project. This is accomplished through a series of lighting simulations that explore and test various architectural parameters that affect daylight-driven circadian lighting, with simultaneous consideration given to photopic lighting availability and visual comfort. The architectural parameters tested in this study included window head height, building orientation, shading devices, visual obstructions to the sky, and room depth. The results show that informed design decisions could maximize circadian potential in a given space, while achieving visually satisfactory luminous environments.

Topical anaesthesia as an adjuvant to local anaesthetic injection in open trigger digit release: a randomized controlled trial.

We conducted a randomized controlled trial to compare pain scores and patient satisfaction between topical anaesthetic cream (5% lidocaine-prilocaine cream) versus placebo cream, applied approximately 90 minutes before local anaesthetic injection for open trigger digit release. One hundred participants were enrolled and randomly allocated into the two groups between May 2019 and February 2020. The visual analogue pain scores and satisfaction scores were measured. Most participants were female with Quinnell Grade 2-3 trigger digits. The pain scores during needle injection, local anaesthetic infiltration, the overall pain and satisfaction scores had no statistically significant differences between groups. There was no correlation between duration of topical anaesthetic drug application and pain scores. Subgroup analysis did not show significant differences in pain scores between genders. No complications were found during the study period. The topical anaesthetic drug was ineffective to use on the palmar skin during open trigger digit release surgery.Level of evidence: II.

Interpositional Arthroplasty With Extensor Digitorum Brevis Tendon in Freiberg Disease.

No consensus has been reached in the treatment of Frieberg disease. Our aim was to evaluate medium- to long-term results of patients with advanced Freiberg disease managed with extensor digitorum brevis tendon interpositional arthroplasty. There were 24 patients (19 females, 5 males) managed with interpositional arthroplasty for advanced Freiberg disease between 2003 and 2015. The mean follow-up was 133.8 (range, 60-198) months. According to Smillie classification, there were 4 grade 3, 13 grade 4, and 7 grade 5 patients. Patients were evaluated preoperatively and at the final follow-up with the American Orthopaedic Foot & Ankle Society (AOFAS) score and metatarsophalangeal joint range of motion and postoperatively with visual analog scale (VAS) and subjective satisfaction evaluation. Joint space was evaluated on x-rays. Mean AOFAS score increased (53.9 to 80.3, P = .001). Eight patients had excellent, 14 had good, and 2 had fair scores. A significant increase was found in dorsiflexion (38.1° [24°-52°] vs 55.3° [34°-65°]; P = .001) and plantarflexion (19.0° [10°-28°] vs 28.6° [19°-39°]; P = .001). Narrowing of the joint space was not seen in any patient, but expansion was determined in all patients (0.39 [0.35-0.47] vs 0.44 [0.41-0.47] cm; P = .002). Of the patients, 9 were very satisfied, 12 were satisfied, 2 were moderately satisfied, and 1 was dissatisfied. The mean postoperative VAS pain score was 1.7 ± 0.9 (0-4). After a minimum 5-year follow-up, most patients with Freiberg disease managed with interpositional arthroplasty using the extensor digitorum brevis tendon had excellent to good functional results with a widening of the joint space. Level IV, retrospective case series.

Refractive, visual, and subjective quality of vision outcomes for very high myopia LASIK from \u2212\u200910.00 to \u2212\u200913.50 diopters

BackgroundTo evaluate laser-assisted in situ keratomileusis (LASIK) outcomes, subjective quality of vision (QoV) and patient satisfaction in eyes with very high myopia (VHM) above − 10.00 diopters (D).MethodsConsecutive myopic and myopic-astigmatism eyes with spherical equivalent (SEQ) ranging between − 10.00 to − 13.50 D underwent LASIK with the WaveLight® Allegretto Wave® Eye-Q 400 Hz excimer laser. Treatment accuracy, efficacy, safety, stability, cylinder vectors, and higher-order aberrations were evaluated, together with subjective QoV and night vision disturbances (NVDs).Results114 eyes had a preoperative SEQ of − 11.02 ± 0.81 D, with a median follow-up of 24 months. A total of 72, 84, and 94% of eyes were within ± 0.50, ± 0.75 and ± 1.00 D of intended SEQ (R2 = 0.71). The efficacy index was 0.93 ± 0.20, with 51 and 81% of eyes achieving 20/20 and 20/25. The astigmatism correction index was 0.95 ± 0.33. The safety index was 1.05 ± 0.12. The average myopic regression was − 0.51 ± 0.38 D. Preoperative QoV scores improved significantly postoperatively (7.5 ± 0.8 vs. 9.1 ± 0.7; P < 0.001), with less NVDs (P < 0.001). Total, spherical and coma root mean square (RMS) postoperative ocular higher-order aberrations were 1.07 ± 0.34, 0.67 ± 0.25, and 0.70 ± 0.40 μm.ConclusionsVery high myopia LASIK between − 10.00 to − 13.50 D is safe and results in good visual outcomes, with high patient satisfaction and a significant improvement in patient-reported QoV after surgery. Appropriately selected patients within this very high myopia group can be included as LASIK candidates.

Comparision of analgesic efficacy of ropivacaine and bupivacaine in rectus sheath block for midline abdominal surgeries

In the modern setting the rectus sheath block (RSB) has been found effective in decreasing opioid requirement after both diagnostic and interventional laparoscopy and laparotomy. Efficacy of rectus sheath block (RSB) using ropivacaine versus bupivacaine for acute postoperative pain relief is not much investigated. 90 patients undergoing elective midline abdominal surgeries under general anaesthesia were randomly divided into three groups of 30 patients each, destined to receive bilateral rectus sheath block using 15 ml on each side (total 30 ml) of 0.25% ropivacaine in Group R, 0.25% bupivacaine in Group B or normal saline in Group C. Three groups were compared regarding time to first rescue analgesic from time of RSB (duration of analgesia), total rescue analgesic (tramadol) consumption in first 10 hours, visual analogue score (VAS), satisfaction score and adverse effects. Mean duration of analgesia was significantly longer in group R (5.78±0.93h) than group B (3.63±0.90 h) and group C (2.37±0.44 h), p&amp;#60;0.001 (group R &amp;#62; group B &amp;#62; group C). This trend was observed in both hernia repair and laparotomy. Rescue analgesic consumption in terms of number of doses was significantly less in Group R (30) than in Group B (38) than in Group C (59), p&amp;#60;0.05. Mean VAS was significantly less and patient satisfaction was significantly better in Group R than in Group B than in Group C, (p&amp;#60;0.001) Bilateral single shot rectus sheath block (RSB) using isobaric ropivacaine (0.25%) or bupivacaine (0.25%) is a safe and effective method of providing postoperative analgesia to patients undergoing midline abdominal surgeries. The lower cardio toxicity profile with the excellent prolonged postoperative analgesia makes ropivacaine an excellent choice for the RSB as compared to bupivacaine

Comparison of visual performance and satisfaction with a bilateral emmetropic vs a bilateral mild myopic target using a spherical monofocal intraocular lens.

To compare the binocular visual outcomes and satisfaction of patients with emmetropia or mild myopia (-0.50 diopters [D]) implanted with a bilateral spherical monofocal IOL. Ophthalmology Department, Humanitas Clinical and Research Center, Rozzano, Milan, Italy. Prospective nonrandomized study. This study comprised 2 groups of 30 patients each. Group 1 included patients implanted with bilateral monofocal IOLs with near emmetropic target (plano to -0.25 D). Group 2 included patients with a postoperative bilateral target of -0.50 D. Both groups underwent uncorrected and corrected distance defocus curves postoperatively and subjective questionnaires were used to investigate patient satisfaction postoperatively. The defocus curve showed a significant difference between Group 1 and Group 2 binocular vision (all P values <.01 except at -3.00 D where P value = .32) with Group 1 seeing significantly better than Group 2 at +1.00, +0.50, and 0 but significantly worse in all other points of the defocus. In addition, patients of Group 2 at 0 D of defocus curve (infinite) had a visual acuity close to 0 logarithm of the minimum angle of resolution (logMAR) (0.03 ± 0.04). The main outcome of Group 2 defocus curves was that, at defocus point 0 D, even if the mean refraction was -0.67 0.15 × 160, mean uncorrected logMAR visual acuity was 0.0 ± 0.06. Bilateral monofocal IOLs implanted with mild myopic target provided better intermediate visual acuity compared with emmetropia at a minimal cost in terms of uncorrected distance visual acuity.

Conceptual Typography Between form Significance and Persuasion

In the rapidly changing world of technology and visual arts, there has begun a cultivating interest in the creative process as a fundamental human requirement, especially in art and design. When considering the conceptual typography, one must be made well aware that the letter, which is the basic component of the word, has become of two importances; which are the readability and achieving a communicative process . The written word thus transforms from being a visual form of communication into an entity of its own, that delivers a certain message that may arouse receiver's emotions . This process is capable of achieving visual satisfaction due to the honesty and simplicity in the composition , as it communicates with the receiver to the point of motivation to participate in decoding the design and reading the hidden meanings . The importance of this study is the scarcity of existing research concerned with the field and with their symbolic connotations. The research aims to achieve persuasion by taking advantage of the symbolic , formal connotations of Arabic letters .To this end, the research follows the descriptive analytical methodology based on gathering information to build its theoretical framework and design a guidelines that helps the graphic designer in achieving the symbolic significance of typography and achieving persuasion by presenting some examples of works designed by the researcher.

Study on the prevention of infection in terminal cancer patients applying epidural analgesia by adding cefazolin to anesthetics: a randomized controlled trial.

To observe the antibacterial effect of adding cefazolin into anesthetics in patients with terminal cancer undergoing long-term epidural analgesia. Patients undergoing epidural analgesia with terminal cancer were randomly divided into two groups: the conventional drug group (group C) and the cefazolin group (group G). Both groups were given levobupivacaine and morphine, while cefazolin was added to group G. The mean arterial pressure (MAP), heart rate (HR), respiratory rates (R), visual analogue scale (VAS) scores, satisfaction and complications of patients in the two groups were observed. 3ml of the used analgesic was taken for bacterial culture when replacing the new analgesic case. HR, MAP, R, VAS scores, dosages of morphine, satisfaction of the analgesic and the complications were not significantly different between the two groups (P>0.05). The overall satisfaction of patients in group G was significantly higher than that in group C (P<0.05). One patient's anesthetics in group C were infected with colibacillus. Four patients in group C got infected in their epidural puncture sites. There was no infection in group G (P<0.05). Adding cefazolin to local anesthetics could effectively prevent bacterial infection and ensured the safety of epidural analgesia for patients with terminal cancer.

Arthroscopic labral debridement versus labral repair for patients with femoroacetabular impingement: A meta-analysis.

Objective:Femoroacetabular impingement (FAI) is a common cause of hip pain and even tearing of the acetabular labrum in young adults and athletes. Either arthroscopic labral debridement (LD) or labral repair (LR) technique for FAI patients is needed to choose. We conducted this systematic review and meta-analysis to compare the clinical outcomes of arthroscopic LD versus LR intervention.Methods:The five studies were acquired from PubMed, Medline, Embase, and Cochrane Library. The data were extracted by two of the coauthors independently and were analyzed by RevMan5.3. Mean differences (MDs), odds ratios (ORs), and 95% confidence intervals (CIs) were calculated. Cochrane Collaboration's Risk of Bias Tool and Newcastle–Ottawa Scale were used to assess risk of bias.Results:Four observational studies and one prospective randomized study were assessed. The methodological quality of the trials indicated a low to moderate risk of bias. The pooled results of Non-Arthritic Hip Score (NAHS), failure rate of surgeries and complications showed that the differences were not statistically significant between the two interventions. The difference of modified Harris Hip Score (mHHS), the Visual Analogue Scale (VAS) score and satisfaction rate was statistically significant between LD and LR intervention, and LR treatment was more effective. Sensitivity analysis proved the stability of the pooled results and there were too less included articles to verify the publication bias.Conclusions:Hip arthroscopy with either LR or LD is an effective treatment for symptomatic FAI. The difference of mHHS, VAS score, and satisfaction rate was statistically significant between LD and LR intervention, and arthroscopic LR could re-create suction-seal effect, potentially reduce microinstability, which demonstrated a trend toward better clinical efficacy and comparable safety compared with LD. The arthroscopic LR technique is recommended as the optical choice for acetabular labrum tear with FAI.

Visual and Refractive Outcomes Following Laser Blended Vision Using Non-linear Aspheric Micro-monovision.

To report 1-year visual and refractive outcomes following PRESBYOND Laser Blended Vision using non-linear aspheric micro-monovision with the MEL 90 platform (Carl Zeiss Meditec GmbH). Data were collected retrospectively for all patients who underwent treatment for simultaneous correction of refractive error and presbyopia from June 2015 to June 2018. Only those patients who completed at least 6 months of follow-up were included in the study. A total of 101 patients with a mean age of 51.05 ± 5.15 years (range: 40 to 65 years), of whom 38 patients had myopic and 63 patients had hyperopic refractive error with or without astigmatism, were included in the study. Mean preoperative spherical equivalent was -3.36 ± 1.86 diopters (D) in the myopia group and +1.75 ± 0.99 D in the hyperopia group. At 1 year, the mean spherical equivalent refraction was +0.13 ± 0.32 D in the distance eye and -1.42 ± 0.33 D (range: -0.88 to -2.50 D) in the near eye in the myopia group and -0.13 ± 0.24 D in the distance eye and -1.28 ± 0.31 D (range: -0.63 to -2.00 D) in the near eye in the hyperopia group. Two eyes in the hyperopia group underwent early enhancement for the near eye at 3 months. Ninety-seven percent of the patients in the myopia group and 96% in the hyperopia group were satisfied with their distance vision. Near vision satisfaction score was 95% for the myopia group and 89% for the hyperopia group. At 1 year, the aspheric micro-monovision protocol resulted in satisfactory and fairly stable visual outcomes in both myopic and hyperopic individuals. [J Refract Surg. 2020;36(5):300-307.].

Impact of posterior vitreous detachment on contrast sensitivity in patients with multifocal intraocular lens.

To investigate posterior vitreous detachment (PVD) and pars plana vitrectomy (PPV) effects on contrast sensitivity function (CSF) in patients with a multifocal intraocular lens (MfIOL). This single-center prospective case-control study analyzed 27 patients with 43 consecutive eyes. Twenty patients with 36 consecutive eyes received MfIOL implantation with either ZLB00 or ZMB00. CSF was measured as the area under the log contrast sensitivity function (AULCSF) in the presence and absence of PVD (PVD+ group and PVD- group, respectively). Seven eyes associated with a symptomatic PVD and severe visual dissatisfaction after MfIOL implantation underwent PPV (symptomatic PVD+ group). CSF was measured prior to and after PPV. The mean AULCSF was significantly lower in the PVD+ group (1.5 ± 0.1) versus the PVD- group (1.7 ± 0.1, p < 0.0001). Major complaints in the symptomatic PVD+ group included floaters (n = 2) and blurry vision (n = 5). The preoperative AULCSF (1.4 ± 0.1) was significantly lower in the symptomatic PVD+ group versus the PVD- group (p < 0.0001) and PVD+ group (p = 0.02). The preoperative AULCSF in the symptomatic PVD+ group was significantly improved after PPV (1.4 vs. 1.7, respectively, p = 0.002). PVD significantly decreased CSF in patients with MfIOL. Patients with symptomatic PVD exhibited the greatest decrease in CSF, which was significantly improved after PPV. Measurement of CSF and careful assessment of PVD may be useful in determining the appropriateness of surgical intervention for improving visual performance and satisfaction in MfIOL patients with symptomatic PVD.

Corneal higher-order aberrations after crosslinking and intrastromal corneal ring segments for keratoconus.

To assess anterior corneal higher-order aberrations (HOAs) after corneal crosslinking (CXL) and intrastromal corneal ring segments (Intacs) used adjunctively. Cornea and refractive surgery practice. Prospective, randomized clinical trial. One hundred fifty-eight eyes of 150 patients were randomized into 2 groups: concurrent, Intacs and CXL during the same session (n = 81), or sequential, Intacs followed by CXL 3 months later (n = 77). Outcomes included changes in total, coma, trefoil, and spherical anterior corneal HOA 6 months after Intacs/CXL. The change in anterior corneal HOAs was correlated with the change in uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), and topography indices of maximum keratometry (Kmax), maximum flattening keratometry (Kmaxflat), and inferior-superior (I-S) ratio. A subjective visual function questionnaire was also analyzed. UDVA, CDVA, Kmax, I-S, and Kmaxflat all improved 6 months after treatment (UDVA = -0.22 ± 0.34, P < .001; CDVA = -0.13 ± 0.24, P < .001; Kmax = -3.1 ± 3.0D, P < .001; I-S = -4.2 ± 5.0 diopters [D], P < .001; Kmaxflat = -7.9 ± 4.0 D, P < .001). Total anterior corneal HOA, vertical coma, and horizontal coma anterior corneal HOAs significantly improved by -1.05 ± 0.93 μm (P < .001), -1.53 ± 1.18 μm (P < .001), and -0.35 ± 0.57 μm (P < .001), respectively. Spherical anterior corneal HOAs increased by 0.24 ± 0.70 μm (P < .001) at 6 months after Intacs/CXL. The change in trefoil was not statistically significant (Ptrefoil0 = .06, Ptrefoil30 = .2). There were no significant differences between the changes in anterior corneal HOAs in the sequential and same-day Intacs/CXL groups. The change in total anterior corneal HOAs was correlated with Kmax, Kmaxflat, and the I-S ratio. There was no correlation between the change in anterior corneal HOAs and the change in visual acuity or visual function survey responses. Total, horizontal coma, and vertical coma anterior corneal HOAs improved after Intacs/CXL. Spherical anterior corneal HOAs increased postoperatively, and there was no change in trefoil. Improvement of anterior corneal HOAs did not correlate with visual acuity improvement or subjective visual satisfaction outcomes.

Unconventional exhibition spaces as an example of the synergy of architecture and art

The article pertains to the relationship between an artwork (painting) and architectural space, as well as the issue of adapting unconventional architectural spaces for an exhibition function in relation to the author's exhibitions presenting the paintings from the same painting series. Different exhibition concepts of each of the exhibitions emphasize the role of a painting in shaping the architectural space and the quality of this space. An artwork becomes a tool that organizes space and influences its quality. At the Faculty of Architecture of Poznań University of Technology, as part of the research project of Professor A.M. Łubowski and J. Stefańska, D.Sc., titled "Artwork in Architecture", there has been research conducted on the correlation of architecture and art. The author was invited to participate in three exhibitions carried out as part of this project. The experiences connected with the project have been described in this article. The problem of using the interiors of buildings whose original purpose was different from exhibiting art , became a part of the author's research carried out in the form of individual and collective exhibitions. Two of them, which took place between 2017 and 2018, showcased paintings from the same series, entitled " I Have Been to Hel(l) and Back. And: Let me Tell you, It Was Wonderful ”, highlighted the importance of the dialogue between architecture and art and created awareness how much this interdependence influences the transformation of the perception of both art and architecture. Appropriate compositional solutions and an appropriate selection of artworks contribute to the complete visual satisfaction of the recipient. Ill-considered combinations cause visual discomfort, which detracts from the potential of both works of art and architectural space. Therefore, it is a need to perform an in-depth analysis of the relationship between the artwork and architectural space, and to avoid conventional, schematic exhibition solutions. The same works placed in various spaces affect the viewer in a different way. The change of the environment influences the change of perception, which creates new interpretative possibilities for the painting’s narrative, while the architectural space gains a wider context of reception through its individualization and increased accessibility. The emotional and intellectual aspect of painting enriches the space with new meanings.

Visual performance comparison of 2 extended depth-of-focus intraocular lenses

To compare the visual acuity and satisfaction outcomes of 2 different concepts of extended depth-of-focus intraocular lenses (EDOF IOLs). University Eye Hospital Bochum, Germany. Prospective randomized comparative clinical trial. Patients undergoing cataract surgery with the implantation of 2 different concept EDOF IOLs. In the first group (IC-8 Group), a monofocal 1-piece Tecnis Z B00 IOL (Johnson & Johnson Vision Care, Inc.) was implanted in the dominant eye, and an IC-8 IOL (AcuFocus) was implanted in the nondominant eye. In the second group (Symfony Group), a Tecnis Symfony IOL (Johnson & Johnson Vision Care, Inc.) was implanted in both eyes. The target refraction of the dominant eye was emmetropia and slight myopia (mini-monovision, -0.75 diopters) in the nondominant eye. Visual and refractive outcomes and patient satisfaction rates were evaluated 3 months postoperatively. This study comprised 76 eyes of 38 patients. No intraoperative or postoperative complications occurred in either group. Target refraction was reached in both groups without statistically significant differences. The uncorrected distance visual acuity (UDVA, photopic and mesopic light conditions) was excellent in both groups with statistically significantly better results in the IC-8 goup (logarithm of the minimum angle of resolution; IC-8 Group (0.1 ± 0.07 logarithm of the minimum angle of resolution [logMAR]; Symfony Group 0.07 ± 0.1 logMAR, P value .02 [photopic]; IC-8 group 0.12 ± 0.09 logMAR, Symfony group 0.22 ± 0.1 logMAR, P value < .01 [mesopic]). Binocular uncorrected intermediate visual acuity (UIVA) and uncorrected near visual acuity (UNVA) were also good in both groups without statistically significant differences (UIVA: IC-8 Group, 0.01 ± 0.07 logMAR, Symfony Group 0.01 ± 0.08 logMAR, P value .35; UNVA: IC-8 Group 0.14 ± 0.11, Symfony Group 0.09 ± 0.08, P value .14). Subjective satisfaction was high in both groups. Both EDOF IOLs provided a very good UDVA with superior results in the IC-8 Group, and a good UIVA and UNVA under photopic light conditions. Subjective patient satisfaction was higher in the IC-8 Group.

Efficacy of Brimonidine Tartarate 0.2% Ophthalmic Solution on Reducing Night Vision Difficulty and Improving Contrast Sensitivity After Laser in Situ Keratomileusis

Abstract Background The relation between scotopic pupil diameter and the optical zone is the most important factor in limiting night vision disturbances after LASIK. Brimonidine Tartrate is a selective alpha-2 agonist which significantly reduces scotopic pupil diameter. It can be used to improve contrast sensitivity and night vision after refractive procedures. Objective Subjective and objective evaluation of the effect of Brimonidine tartrate 0.2% ophthalmic solution on improving post-LASIK night vision complaints by studying its effect on the pupil diameter, contrast sensitivity, aberrations and symptoms of night vision difficulties. Patients and Methods This prospective study was conducted upon 34 eyes of 17 patients suffering from night vision difficulties after uneventful lasik surgery. They received one drop of Brimonidine Tartrate 0. 2% ophthalmic solution on each eye and were asked to apply one drop in each eye daily for two months. Testing was performed before drops instillation, 30 minutes, 4 hours after instillation and after 2 months of regular brimonidine use. All patients had photopic and scotopic pupillometry using Zywave aberrometer built in pupillometer, Contrast sensitivity testing using Pelli-Robson chart, Aberrometry using Zywave aberrometer. Visual night complaints was assessed with an FDA approved questionnaire taken from (LASIK quality of life collaboration project). Results There was a significant decrease in mean photopic and scotopic pupil diameter, spherical and total aberrations after 30 minutes, 4 hours and 2 month of once daily use of Brimonidine. Also there was a significant improvement of contrast sensitivity that remained at acceptable levels along the follow up time. All patients showed a significant visual satisfaction after 2 month of treatment. Conclusion Brimonidine tartrate 0. 2% ophthalmic solution can be effective in reducing night vision difficulties after LASIK by reducing scotopic pupil diameter, improving contrast sensitivity and decreasing higher order aberrations.

The Effect of Postoperative Opioid Prescription Refills on Achieving Meaningful Clinical Outcomes After Hip Arthroscopy for Femoroacetabular Impingement Syndrome

To determine whether requiring postoperative opioid refills has an effect on both baseline and postoperative functional scores, as well as rates of achieving clinical success 2 years after hip arthroscopy for femoroacetabular impingement syndrome (FAIS). Data from consecutive patients undergoing hip arthroscopy for FAIS from January 2012 to December 2016 were analyzed. Patients with at least 1 postoperative opioid refill were matched 1:2 by age and body mass index to patients not requiring refills. Preoperative and postoperative patient-reported outcomes including the Hip Outcome Score-Activities of Daily Living Subscale, HOS-Sports Subscale, and modified Hip Harris Score, as well as visual analog scale (VAS) pain and satisfaction surveys, were compared between the 2 groups, as well as between patients who requested 1 refill versus those requiring 2 or more refills. The minimal clinically important difference and patient acceptable symptomatic state (PASS) were calculated for the study group and compared between patient groups. A total of 128 patients (14.5%) requesting at least 1 postoperative opioid refill and 256 with no refills were included in the study. Analysis showed that the refill group had lower patient-reported outcomes (P < .05 for all), a lower VAS satisfaction score average (73.2 ± 30.7 vs 80.1± 25.9, P= .029), and a higher VAS pain score average (27.2 ± 26.1 vs 19.9 ± 22.7, P= .007). Similar trends were seen when patients with 1 refill were compared with those with 2 or more refills. Analysis of meaningful clinical outcomes showed that patients in the refill group had lower rates of achieving the PASS (68.3% vs 77.2%, P= .006). However, there were no statistically significant differences in achieving the minimal clinically important difference between the 2 groups (P > .05 for all). Patients undergoing hip arthroscopy for FAIS who require 1 or more opioid refills postoperatively are likely to have lower baseline and postoperative functional scores, as well as to achieve the PASS at lower rates, compared with patients who do not require an additional opioid prescription to what is routinely given after surgery. Level III, retrospective case-control study.

Long-Term Outcome Following Revision Total Knee Arthroplasty is Associated With Indication for Revision

BackgroundThere is limited information about long-term clinical outcomes following revision total knee arthroplasty (TKA) in relation to the indication for revision. Previously, a clear relation between indication for revision and clinical outcome was shown after 2 years. Present study evaluated (1) whether the reported association at 2 year remains present at 7.5 years, and (2) how clinical outcome at 7.5 years developed compared to baseline and 2-year follow-up, and (3) whether patients had additional adverse events. MethodsA cohort of 129 patients with a total system revision TKA was selected. Range of motion, Visual Analog Scale for pain and satisfaction, and clinical and functional Knee Society Score were obtained preoperatively, at 3 months, 1, 2, and 7.5 years. Reasons for revision were septic loosening, aseptic loosening, malposition, instability, and severe stiffness. ResultsPatients revised for severe stiffness had significantly worse outcomes. No difference was found between the other indications. The clinical outcome after revision TKA at 7.5 years remained stable for septic and aseptic loosening, malposition, and instability but deteriorated slightly for the severe stiffness group. Visual Analog Scale satisfaction remained constant for all indications. There were 11 additional complications between 2- and 7.5-year follow-up, 9 of which necessitated reoperation. ConclusionAll indications except severe stiffness had a similar clinical outcome which was maintained up to 7.5-year follow-up. The severe stiffness group had worse outcomes and deteriorated slightly at longer follow-up. Outcome at 3 months seems predictive for long-term outcome. Additional complications did not differ significantly for the different reasons for revision. Level of EvidenceLevel III, prognostic study.
