A … BACKGROUND: With the increased efforts to adopt health information technology in the healthcare field, many innovative devices have emerged to improve patient care, increase efficiency, and decrease healthcare costs. A recent addition is smart glasses: web-connected glasses that can present data o nto the lenses and record images or videos through a front-facing camera. OBJECTIVE: In this article, we review the most salient uses of smart glasses in healthcare, while also denoting their limitations including practical capabilities and patient confidentiality. METHODS: Using keywords including, but not limited to, ``smart glasses'', ``healthcare'', ``evaluation'', ``privacy'', and ``development'', we conducted a search on Ovid-MEDLINE, PubMed, and Google Scholar. A total of 71 studies were included in this review. RESULTS: Smart glasses have been adopted into the healthcare setting with several useful applications including, hands-free photo and video documentation, telemedicine, Electronic Health Record retrieval and input, rapid diagnostic test analysis, education, and live broadcasting. CONCLUSIONS: In order for the device to gain acceptance by medical professionals, smart glasses will need to be tailored to fit the needs of medical and surgical sub-specialties. Future studies will need to qualitatively assess the benefits of smart glasses as an adjunct to the current health information technology infrastructure.

The objective of the present study was to compare the accuracy (trueness and precision) of digital impressions of the full arch with that of conventional impressions on the in-vitro model. For this purpose, a master model was acquired with a new reference scanning process, the measuring trueness of which was +/- 4.1 microm and the precision +/- 2.5 microm. On the one hand, conventional impressions and then plaster models (n = 5) were produced from this master model, and on the other hand, digital impressions were made with the Cerec AC Bluecam and the Lava COS system (each n = 5). The plaster models were also scanned with the reference scanner. The available data records were superimposed and the differences determined. The deviation from the master model defines the trueness of the impression method. The deviations of the models among one another demonstrate the precision of the method. The trueness of the impressions was 55 +/- 21.8 microm in the conventional impression group, for digital impressions with Cerec Bluecam it was 49 +/- 14.2 microm and for digital impressions with Lava COS 40.3 +/- 14.1 microm. The precision was 61.3 +/- 17.9 microm for conventional impression with Impregum, 30.9 +/- 7.1 microm for digital impression with the Cerec Bluecam and 60.1 +/- 31.3 microm for digital impression with Lava COS. These in-vitro results show that accuracy of the digital impression is similar to that of the conventional impression. These results will have to be confirmed in further clinical studies.

Several papers on reliability of refraction have … The repeatability (reliability) of methods of measuring refractive error is an important consideration in patient management decisions and in research design and interpretation. Several papers on reliability of refraction have appeared in the literature.Studies on the reliability of conventional clinical refraction, including repeated refractions by the same examiner (intraexaminer reliability) and comparisons of the results obtained by different examiners (interexaminer reliability), were reviewed. Studies comparing the results obtained by autorefractors and conventional subjective refraction were also reviewed.The intraexaminer reliability and interexaminer reliability of subjective refraction in most studies were close to 80 percent agreement within +/- 0.25D and 95 percent agreement within +/- 0.50D for spherical equivalent, sphere power, and cylinder power. The reliability of most autorefractors is similar to the reliability of conventional subjective refraction.The results of the reliability studies support Bannon's 1977 conclusion that conventional subjective refraction is reliable within 0.25 to 0.50D. Studies comparing objective autorefractors and conventional subjective refraction indicate that these autorefractors are satisfactory for a preliminary refraction but are not satisfactory as substitutes for conventional subjective refraction.

Ease of handling and, more importantly, … Surveying intraoral structures by optical means has reached the stage where it is being discussed as a serious clinical alternative to conventional impression taking. Ease of handling and, more importantly, accuracy are important criteria for the clinical suitability of these systems. This article presents a new intraoral camera for the Cerec procedure. It reports on a study investigating the accuracy of this camera and its potential clinical indications. Single-tooth and quadrant images were taken with the camera and the results compared to those obtained with a reference scanner and with the previous 3D camera model. Differences were analyzed by superimposing the data records. Accuracy was higher with the new camera than with the previous model, reaching up to 19 microm in single-tooth images. Quadrant images can also be taken with sufficient accuracy (ca 35 microm) and are simple to perform in clinical practice, thanks to built-in shake detection in automatic capture mode.

While time to heal was similar for both groups, the patients using Granuflex Extra Thin experienced less pain (P < 0.001), required less analgesia (P = 0.0154) and were able to carry out their normal daily activities including bathing or showering without affecting the dressing or the wound. Patient satisfaction with the new dressing appeared to be very high especially in those patients who pursued an active lifestyle.

With centres in nine countries, its common goal is to create, maintain and disseminate systematic reviews of randomized controlled trials in an effort to bring clinicians the most current, accurate evidence about medical treatments available around the world. The future of the collaboration will depend largely on whether the methodology of their reviews can be shown to be valid and to produce consistently relevant and timely reviews.

Patients were examined in-person by one of three board-certified dermatologists who provided clinical diagnoses. Digital photos were obtained on all patients and were evaluated as computer images by a panel of dermatologists.There was 83% concordance between in-person versus digital photo diagnoses. Intradermatologist concordance averaged 84%, and interdermatologist concordance averaged 81%. Decision confidence was rated as "very definite" to "definite" 62% of the time. Concordance with biopsy results was achieved in 76% of the cases. Image sharpness and color quality were rated "good" to "excellent" 83% and 93% of the time, respectively.Digital photography for store-and-forward teledermatology produces high-quality images and diagnostic concordance rates that compare favorably with in-person clinical diagnoses.

Clinical photographs should always be taken with the … Standard photographic technique in plastic surgery is an important topic that has been stressed in the discipline over the past several years. Clinical photographs should always be taken with the same camera lens, lens setting, lighting, film, and patient position to ensure reproducibility and to enable valid pre- and postoperative comparisons. A 35-mm single lens reflex camera is highly recommended for this type of photography. Two lenses are suggested, one with a focal length range of 50 to 60 mm and one with a focal length range of 90 to 105 mm. Both should have macro capability. Two or more flash units are recommended, either camera-mounted or a studio system set-up in the office. Using the patient preparation method and technique outlined in the text, the Standards in Clinical Photography achieve consistency from patient to patient and also in the same patient in pre- and postoperative photographs. Henceforth, the information discussed in the article forms the basis for standard views, regardless of the image-capture medium. (Plast. Reconstr. Surg. 102: 559, 1998.)

Storage of study models is problematic in terms of space and cost. Ayoub et al. introduced a new technique based on the recent advances in stereophotogrammetry for archiving dental study models in a digital format. However, assessment of the accuracy of the generated three-dimensional (3D) models has not been carried out yet. It was the aim of this study to evaluate the accuracy of this technique.Design: A comparative assessment between direct measurements of dental study models and measurements of computer generated 3D images of the same study models was performed.Materials and methods: Twenty-two dental study models stored at Glasgow Dental Hospital and School for the purposes of research were used in the study. The models were captured in three dimensions using a photostereometric technique and stored in digital format.Main Outcome Measures: Measurements were conducted directly on dental study models and on the computer generated 3D images using Euclidean Distance Matrix Analysis. The difference between the two sets of measurements was statistically analysed using a two-sample t-test.Results: The average difference between measurements of dental casts and 3D images was 0.27 mm. This difference was within the range of operator errors (0.10–0.48 mm) and was not statistically significant (P < 0.05).Conclusion: This study shows that it is possible to use 3D imaging to store dental study models for treatment monitoring and research with a satisfactory degree of accuracy.

We propose a simple three-step … Creating or recreating an aesthetically pleasing breast shape in reconstructive and aesthetic breast surgery is an act that most experienced "breast" surgeons will find self-evident. We propose a simple three-step philosophical and hands-on approach that will make it easier for young and unexperienced plastic surgeons to not only analyze the problematic breast but also come up with an easy surgical strategy to create reproducible results.This is Part I of four parts describing the three-step principle being applied in reconstructive and aesthetic breast surgery. Part I explains how to analyze a problematic breast by understanding the three main anatomical features of a breast and how they interact: the footprint, the conus of the breast, and the skin envelope. Part II deals with reconstructions after complete mastectomy and Part III covers reconstruction after breast conservation surgery. Finally, Part IV applies the same principles in the field of aesthetic breast surgery. Throughout these four parts, the three-step principle will be the red line to fall back on to define the problem and to propose a solution.

DISGUISE OR CONSENT: PROBLEMS AND RECOMMENDATIONS CONCERNING THE PUBLICATION AND PRESENTATION OF CLINICAL MATERIAL

The strategies of dealing with this dilemma can be classified as follows: (1) thick disguise, (2) patient consent, (3) the process approach, (4) the use of composites and (5) the use of a colleague as author. Some of these options may, of course, be used in combination with one another. All of these methods have a place, and the author argues against a uniform approach. Each of these strategies is discussed in terms of its advantages and disadvantages. While no choice is without various risks, some guidelines are offered to assist analysts who wish to present or write about clinical cases.

Before establishing them as a criterion standard, however, meticulous evaluation of their precision and accuracy under both ideal and clinical circumstances is essential. Potential sources of error need to be identified and addressed. Materials and Methods: Under ideal circumstances, a phantom is used to examine the precision and accuracy of the 3dMD system. A clinical setting is simulated by varying different parameters such as angle, distance, and system reregistration, as well as data evaluation under different levels of magnification. Results: The handling of the system was unproblematic in matters of data acquisition and data analysis. It was very reliable, with a mean global error of 0.2 mm (range, 0.1-0.5 mm) for mannequin head measurements. Neither the position of the head nor that of the camera influenced these parameters. New referencing of the system did not influence precision and accuracy. Conclusions: The precision and accuracy of the tested system are more than sufficient for clinical needs and greater than those of other methods, such as direct anthropometry and two-dimensional photography. The evaluated system can be recommended for evaluation and documentation of the facial surface and could offer new opportunities in reconstructive, orthognathic, and craniofacial surgery.

Over the last two decades, the number of web‐based pathology resources has expanded dramatically with centralized pathological resources being delivered to many students simultaneously. Recently, whole slide imaging technology allows glass slides to be scanned and viewed on a computer screen via dedicated software. This technology is referred to as virtual microscopy and has created enormous opportunities in pathological training and education. Students are able to learn key histopathological skills, e.g. to identify areas of diagnostic relevance from an entire slide, via a web‐based computer environment. Students no longer need to be in the same room as the slides. New human–computer interfaces are also being developed using more natural touch technology to enhance the manipulation of digitized slides. Several major initiatives are also underway introducing online competency and diagnostic decision analysis using virtual microscopy and have important future roles in accreditation and recertification. Finally, researchers are investigating how pathological decision‐making is achieved using virtual microscopy and modern eye‐tracking devices. Virtual microscopy and digital pathology will continue to improve how pathology training and education is delivered.

It is timely to verify whether the several scanners proposed for full-arch digital impressions have been tested under clinical conditions for validity, repeatability, reproducibility, as well as for time efficiency, and patient acceptance. An electronic search of the literature was conducted through PubMed, Scopus, Cochrane Library, Web of Science, and Embase, entering the query terms 'digital impression', 'intraoral digital impression', 'intraoral scanning', 'intraoral scanner', 'intraoral digital scanner', combined by the Boolean operator 'OR'. No language or time limitation was applied. Only studies where digital full-arch impressions had been recorded intraorally were considered. In only eight studies full-arch scans had been performed intraorally. Only four studies reported data on validity, repeatability, reproducibility of digital measurements and their samples were limited to subjects in complete permanent dentition. Only two intraoral scanners, Lava COS and iTero, were tested. Scanning times were measured in six studies and varied largely. Patients' acceptance of intraoral scanning was evaluated in four studies, but it was not specifically assessed for children. The scientific evidence so far collected on intraoral scanning is neither exhaustive, nor up-to-date. Data from full-arch scans performed in children should be collected. For a meaningful assessment of time efficiency, agreement should be reached on the procedural steps to be included in the computation of scanning time.

The ability to change display units facilitates adaption to a variety of users and applications. The program is not to be viewed as a stand-alone system. Rather it is intended to integrate with other pieces of imaging software and with the standard tools on the workstation «desk top». This functionality is coupled with a user interface that makes all major functions evident. The functions typically found on a viewing console are made readily available, giving the clinical user a feeling of familiarity. The online help system and paper documentation, whilst comprehensive, are intended to be devices of last resort. DispImage is not intended as a day-to-day clinical tool that might take the place of a clinicians viewing console. Rather it is a development and research tool that can facilitate in the construction and evaluation of systems and techniques. It has proved valuable in numerous application areas and has been used out of preference at some sites where more developed and sophisticated tools have been available.

In part I of this article, photomicrographs of the dentinal smear layer and three category I first-generation dentin-adhesive interfaces are presented. The photomicrographs show that the wetting and penetration of the first-generation dentinal adhesives were not adequate to produce high shear bond strengths. When the category I adhesives were tested for shear bond strength, failures occurred at the interface or in the resin adhesive. Future articles will explain wetting and adhesive performance of category II and III adhesives.

Flowable resin composites as "filled adhesives": literature review and clinical recommendations.

The clinical significance of many such studies can be questioned. To function clinically, bond strength must develop more quickly than the shrinkage stress. Oxygen inhibition of extremely thin resin layers prohibits establishment of the bond, perhaps particularly relevant for single-component dentin bonding agents. Use of thicker layers of radiolucent hydrophilic bonding materials can lead to difficulties during subsequent radiographic diagnosis and may contribute to degradation at enamel margins. Shrinkage stress is influenced significantly by many factors. The cavity geometry probably plays the most important role but cannot be controlled to any major extent by the operator. Shrinkage and modulus kinetics are also critical, involving variables such as content and type of monomers, the catalyst system, and the light intensity. In general, a high modulus of elasticity or more rapid polymerization leads to increased shrinkage stress. Combining a single-component adhesive as a dentin primer with a highly radiopaque flowable resin composite as a filled adhesive may help overcome these difficulties.

The sample was randomly divided into three groups of 75 patients each. The same type of post was used in all patients within a group: group 1 = Aesthetic Plus; group 2 = DT; and group 3 = FRC Postec. For bonding the post, a light-curing adhesive (One-Step) and a dual-curing resin cement (Duo-Link) were applied in group 1 and 2 roots, whereas self-curing materials (Excite DSC as adhesive and MultiLink as resin cement) were used in group 3. After 6, 12, and 24 months, patients were recalled, and a clinical and radiographic examination was performed. For some patients, 30-month follow-up data were also collected.Debonding of the post occurrred in eight cases (3.5%); in another six cases, a recurrence of the periapical lesion was reported.The statistical analysis did not reveal any significant difference in the survival rate of the tested posts, suggesting that all are equally and sufficiently reliable for clinical use.

This book was pivotal in the development of psychology and physiology as it marked the first time that photography had been used to illustrate, and therefore 'prove', a series of experiments. In this volume, Andrew Cuthbertson has provided an English translation of Duchenne, complete with a reproduction of the marvellous Album of photographs. The four commentary chapters by modern experts describe the relevance of Duchenne's findings to the fields of experimental psychology, plastic surgery, neurology and physiology. This book will therefore be valued by all those who deal with facial expression, including psychologists, physicians and those involved in the fine arts and photography.

Scenario analysis was employed to calculate the cost of disposable (Goldmann applanation tonometry (GAT) tips, rebound tonometry tips, gonioscopy lenses) and reusable equipment (GAT tips and gonioscopy lenses) as well as sanitization over 2, 5, and 10 years at a single institution. To account for variability in scenario modeling, a sensitivity analysis was additionally performed. The main outcome measure was cost differences for disposable equipment compared to reusable equipment with sanitization. Results: The total volume included was 80,356 patient visits. Accounting for variable costs, the additional cost associated with disposable tonometry (GAT or rebound tonometry tips) instead of reusable GAT was $118,723 over 2 years and $603,924 over 10 years. Assuming a gonioscopy frequency of 3.2%, the additional cost associated with disposable gonioscopy lenses was $171,100 at 5 years and $361,237 at 10 years. At a gonioscopy frequency of 10%, the additional cost associated with disposable lenses was $1,208,096 without inflation at 10 years. Overall, the total additional cost associated with disposable tonometry tips and gonioscopy lenses over reusable versions of this equipment was $965,161 over 10 years at a single institution. Conclusion: A widespread transition from reusable to disposable tonometry and gonioscopy equipment was associated with an additional cost of $965,161 over a 10- year period at a single institution.

Retention is the set of means, processes or devices that contribute to maintain the teeth in the position and the arches in the shape given by the treatment as long … Retention is the set of means, processes or devices that contribute to maintain the teeth in the position and the arches in the shape given by the treatment as long as possible. Given the heterogeneity of practices, devices used and follow-up modalities, the French Society of Dentofacial Orthopedics (Société Française d'Orthopédie Dento-faciale or SFODF), a scientific society, has proposed Clinical Practice Guidelines (CPG) for orthodontic retention. This article presents the method used to develop the CPG full-text and the guidelines produced. A review of the literature was carried out after a bibliographic search of databases. The CPG full-text and guidelines were drafted, graded according to the level of evidence, then reread, discussed and validated by the workgroup's experts. A second review by a group of external experts was then carried out before final validation of the CPG for publication. Of 652 articles selected, 53 met the inclusion criteria and were used to prepare the CPG full-text containing 41 grade C items and 23 expert agreements, constituting 40 guidelines. There is still no consensus on the choice of materials. The literature remains poor on the functions. Some appliances which are more used in France are poorly documented in the literature. The CPGs provide recommendations on the factors to consider before using a retainer, the effectiveness of the different devices, their failures and adverse effects, as well as the follow-up procedures.

Methods Twenty‐five expert endocrine surgeons, endocrinologists, surgical oncology, and ear‐nose‐and‐throat surgeons were invited to participate in a modified Delphi process. Initial domains for consideration were determined from literature review and were compatible with domains previously endorsed by the American Thyroid Association. Consensus for individual variables was predefined as mean > 70th percentile and a low disagreement index (< 1.0). An academic working party reviewed the indeterminate domains to reach a final consensus. Results Of 25 invited, 24 participated in the study. Two rounds of questionnaires were conducted. Consensus was reached for 39 data elements across five domains and were included in the final SOR template. A further eight data elements were shortlisted for inclusion in a secondary list of desirable but optional data elements. Conclusion We developed a consensus‐derived SOR for thyroid surgery. Future studies are required to review the uptake and utility of this template in a clinical setting. There is a literary void regarding the role of SOR for parathyroid and adrenal surgery and this could be approached with similar methodology.

METHODS: We conducted a randomized controlled trial of obstetrician–gynecologist trainee and attending surgeons at University of Pittsburgh Magee-Womens Hospital. During the learning phase, participants were guided through a 50-step procedure that used a Montessori lockbox, lighted switchboard, and simple tools. After the procedure, participants were stratified by training level and block randomized to one of three writing exercises: control, templated operative report, and freestyle operative report. During the testing phase 1 week later, participants were asked to complete the procedure from memory. The primary outcome was the testing phase performance score (out of 100 possible points), and secondary outcomes include operative report accuracy, procedure time, predicted future performance, and perceived influence of documentation. RESULTS: Forty-eight participants were randomized to 16 participants per group, with 0% dropout. Completion of a templated or freestyle operative note resulted in significantly improved performance during the testing phase (control: mean 50.9, SD 13.6; template: mean 60.9, SD 11.9; freestyle: mean 62.1, SD 13.3; P <.05). In addition, participants who completed an operative report completed the procedure more quickly than those in the control group ( P <.05). Operative report accuracy during the learning phase was significantly correlated with testing day performance ( P <.005). Although the majority of participants who completed an operative report perceived that the documentation had a positive influence on their performance, this did not translate into differences in the perceived difficulty of the task or in their predictions for testing day performance. CONCLUSION: Operative report documentation significantly improved surgeons' procedural memory and task completion time 1 week after learning a new procedure. Trainee-written operative reports may be one means of promoting surgical memory and learning, and formal operative report education should be incorporated into surgical training programs.

The proposed approach integrates advanced natural language processing (NLP) techniques with medical thesauri and ontologies to enhance the efficiency of medical data analysis and structuring. The BioBERT neural language model was employed to generate clinical descriptions for each image, transforming natural language expressions into a vector space. These vector representations were then compared with selected semantic concepts from medical thesauri (e.g., SNOMED CT) using cosine similarity, enabling the automatic selection of the most relevant semantic tag. In the experimental part of the study, automatic semantic labeling was performed on 100 images from the ISIC 2020 GroundTruth dataset. Key concepts reflecting visual features of skin tumors. The results demonstrated a high level of agreement between automatically assigned tags and actual diagnoses. This approach significantly accelerates and standardizes the image labeling process, reduces subjectivity, and improves the reproducibility of results. The developed algorithm can be integrated into dermatology information systems to automate diagnostics, enable intelligent data sorting, and support the development of recommendation systems.

This study aimed to evaluate the quality of clinical photographs used in dermatology referrals, to identify discrepancies between specialties' perceptions, and to determine the general awareness of proper storage and security of clinical photographs. Methods: A 43-question survey, based on previously validated questionnaires, was administered to general and family medicine (GFM) doctors and to dermatologists at an academic referral hospital in Porto, Portugal. The survey assessed demographics, photo-taking habits, perceived photo quality, adequacy of clinical information, and opinions on the role of photography in the referral process. Quantitative statistical methods were used to analyze questionnaire responses. Results: A total of 65 physicians participated (18 dermatologists and 47 GFM doctors). Significant differences were observed between the two groups. While 36.2% of GFMs rated their submitted photos as high- or very-high-quality, none of the dermatologists rated the received photos as high-quality, with 83.3% rating them as average (p = 0.012). Regarding clinical information, 46.8% of GFMs reported consistently sending enough information, while no dermatologists reported always receiving sufficient information (p < 0.001). Most respondents (76.9%) agreed that the quality of photographs is important in diagnosis and treatment. Conclusions: The findings reveal a discrepancy between GFM doctors' and dermatologists' perceptions of photograph quality and information sufficiency in dermatology referrals. Standardized guidelines and educational interventions are necessary to improve the quality and consistency of clinical photographs, thereby enhancing communication between healthcare providers and ensuring patient data privacy and security.

Digital Single Lens Reflex (DSLR) cameras with a ring flash have been established as a gold standard for clinical photography for many years, however smartphones are increasingly being utilized by both patients and clinicians due to their convenience, cost effectiveness and good accessibility. Aims/ Objectives This study compared the image quality, dimensional accuracy, ease of use and accuracy of shade representation of images produced by recent flagship smartphones versus DSLR cameras with a ring flash Material and methods A sample of four recent smartphones and three semi-professional DSLR cameras were compared taking a comprehensive set of orthodontic intra and extra oral clinical photographs. The following outcome measures were assessed for each device: Camera sensor size, image quality, ease of use, dimensional accuracy and colour shade representation. Results DSLR cameras with a ring flash were statistically significantly superior to smartphones for camera sensor size, image quality rating and dimensional accuracy. There was no significant difference between all devices for their ease-of-use rating or accuracy of colour shade representation. Conclusion Based on the results of this study, the authors recommend the use of DSLR cameras with a ring flash as a gold standard for clinical photography due to reduced quality rating and image distortion produced by many smartphone cameras.

In high-end manufacturing these tasks would be considered simple routine with error rates of 0.1% to 0.5%. <bold>MATERIALS AND METHODS: </bold>Documentation accuracy of six key events over 10 consecutive weeks was measured. Error rates, delays in documentation, and environmental variables including operating room (OR) size, number of nurses per OR, and service line were recorded. Statistical methods included regression models, correlation analysis and analysis of variance (ANOVA). <bold>RESULTS: </bold>From 202 cases, 98.10% of 1240 events were captured, revealing an overall error rate of 17.01%. Delays in documentation were observed in 51.40% of events. Larger ORs, multiple nurses documenting, and delays over 20 minutes were linked to higher error rates. Error rates increased from 1.30% without delays to 38.43% with delays exceeding 20 minutes. <bold>DISCUSSION: </bold>Documentation error rates for time-stamping tasks were at a minimum 2.6 times higher than predicted and increased significantly with delays in documentation indicating that environmental complexity and stress diminish human tasks performance as well as recall of events. <bold>CONCLUSION:</bold> Our data indicate that error rates in the healthcare space are higher than in the manufacturing space for tasks of identical or similar complexity. Given the certainty and immutability of human error in task performance, our findings highlight the need for technologies to improve accuracy of EHR documentation in this critical and high complexity space.
