Are cognitive researchers ignoring their senses? The problem of sensory deficit in cognitive aging research.

Sensory impairments are common in older adult populations and have notable impacts on aging outcomes. Relationships between sensory and cognitive functions have been clearly established, though the mechanisms underlying those relationships are not fully understood. Given the growing burden of dementia, older adults with sensory deficits are an important and growing population to study in cognitive aging research. Yet, cognitive research sometimes excludes those with uncorrected significant/severe sensory deficits and often poorly or inconsistently assesses those deficits. Observational and interventional studies that exclude participants with sensory deficits will be limited in their generalizability to the narrower subset of the older adult population without vision or hearing impairment and may be missing an opportunity to study a growing population of older adults at higher risk of cognitive impairment. Strategies exist for adapting cognitive testing instruments, and inroads could be made into collecting normative data to inform ongoing research. Bringing together psychometricians with researchers who specialize in vision and hearing impairments could launch highly innovative research on both measurement methods and cognitive disease etiology, as sensory organs provide readily accessible neuronal and vascular beds that may show pathology earlier and elucidate innovative screening opportunities for early signs of cognitive disease.

Long-term and serious harms of medical cannabis and cannabinoids for chronic pain: a systematic review of non-randomised studies.

OBJECTIVE: To establish the prevalence of long-term and serious harms of medical cannabis for chronic pain. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE, EMBASE, PsycINFO and CENTRAL from inception to 1 April 2020. STUDY SELECTION: Non-randomised studies reporting on harms of medical cannabis or cannabinoids in adults or children living with chronic pain with ≥4 weeks of follow-up. DATA EXTRACTION AND SYNTHESIS: A parallel guideline panel provided input on the design and interpretation of the systematic review, including selection of adverse events for consideration. Two reviewers, working independently and in duplicate, screened the search results, extracted data and assessed risk of bias. We used random-effects models for all meta-analyses and the Grades of Recommendations, Assessment, Development and Evaluation approach to evaluate the certainty of evidence. RESULTS: We identified 39 eligible studies that enrolled 12 143 adult patients with chronic pain. Very low certainty evidence suggests that adverse events are common (prevalence: 26.0%; 95% CI 13.2% to 41.2%) among users of medical cannabis for chronic pain, particularly any psychiatric adverse events (prevalence: 13.5%; 95% CI 2.6% to 30.6%). Very low certainty evidence, however, indicates serious adverse events, adverse events leading to discontinuation, cognitive adverse events, accidents and injuries, and dependence and withdrawal syndrome are less common and each typically occur in fewer than 1 in 20 patients. We compared studies with <24 weeks and ≥24 weeks of cannabis use and found more adverse events reported among studies with longer follow-up (test for interaction p<0.01). Palmitoylethanolamide was usually associated with few to no adverse events. We found insufficient evidence addressing the harms of medical cannabis compared with other pain management options, such as opioids. CONCLUSIONS: There is very low certainty evidence that adverse events are common among people living with chronic pain who use medical cannabis or cannabinoids, but that few patients experience serious adverse events.

Medical cannabis or cannabinoids for chronic non-cancer and cancer related pain: a systematic review and meta-analysis of randomised clinical trials.

OBJECTIVE: To determine the benefits and harms of medical cannabis and cannabinoids for chronic pain. DESIGN: Systematic review and meta-analysis. DATA SOURCES: MEDLINE, EMBASE, AMED, PsycInfo, CENTRAL, CINAHL, PubMed, Web of Science, Cannabis-Med, Epistemonikos, and trial registries up to January 2021. STUDY SELECTION: Randomised clinical trials of medical cannabis or cannabinoids versus any non-cannabis control for chronic pain at ≥1 month follow-up. DATA EXTRACTION AND SYNTHESIS: Paired reviewers independently assessed risk of bias and extracted data. We performed random-effects models meta-analyses and used GRADE to assess the certainty of evidence. RESULTS: A total of 32 trials with 5174 adult patients were included, 29 of which compared medical cannabis or cannabinoids with placebo. Medical cannabis was administered orally (n=30) or topically (n=2). Clinical populations included chronic non-cancer pain (n=28) and cancer related pain (n=4). Length of follow-up ranged from 1 to 5.5 months. Compared with placebo, non-inhaled medical cannabis probably results in a small increase in the proportion of patients experiencing at least the minimally important difference (MID) of 1 cm (on a 10 cm visual analogue scale (VAS)) in pain relief (modelled risk difference (RD) of 10% (95% confidence interval 5% to 15%), based on a weighted mean difference (WMD) of -0.50 cm (95% CI -0.75 to -0.25 cm, moderate certainty)). Medical cannabis taken orally results in a very small improvement in physical functioning (4% modelled RD (0.1% to 8%) for achieving at least the MID of 10 points on the 100-point SF-36 physical functioning scale, WMD of 1.67 points (0.03 to 3.31, high certainty)), and a small improvement in sleep quality (6% modelled RD (2% to 9%) for achieving at least the MID of 1 cm on a 10 cm VAS, WMD of -0.35 cm (-0.55 to -0.14 cm, high certainty)). Medical cannabis taken orally does not improve emotional, role, or social functioning (high certainty). Moderate certainty evidence shows that medical cannabis taken orally probably results in a small increased risk of transient cognitive impairment (RD 2% (0.1% to 6%)), vomiting (RD 3% (0.4% to 6%)), drowsiness (RD 5% (2% to 8%)), impaired attention (RD 3% (1% to 8%)), and nausea (RD 5% (2% to 8%)), but not diarrhoea; while high certainty evidence shows greater increased risk of dizziness (RD 9% (5% to 14%)) for trials with <3 months follow-up versus RD 28% (18% to 43%) for trials with ≥3 months follow-up; interaction test P=0.003; moderate credibility of subgroup effect). CONCLUSIONS: Moderate to high certainty evidence shows that non-inhaled medical cannabis or cannabinoids results in a small to very small improvement in pain relief, physical functioning, and sleep quality among patients with chronic pain, along with several transient adverse side effects, compared with placebo. The accompanying BMJ Rapid Recommendation provides contextualised guidance based on this body of evidence. SYSTEMATIC REVIEW REGISTRATION: https://osf.io/3pwn2.

Racial Disparities in Health Care Resource Utilization After Pediatric Cervical and/or Thoracic Spinal Injuries.

OBJECTIVE: This study aimed to investigate the impact of race on hospital length of stay (LOS) and hospital complications among pediatric patients with cervical/thoracic injury. METHODS: A retrospective cohort was performed using the 2017 admission year from 753 facilities utilizing the National Trauma Data Bank. All pediatric patients with cervical/thoracic spine injuries were identified using the ICD-10-CM diagnosis coding system. These patients were segregated by their race, non-Hispanic white (NHW), non-Hispanic black (NHB), non-Hispanic Asian (NHA), and Hispanic (H). Demographic, hospital variable, hospital complications, and LOS data were collected. A linear and logistic multivariate regression analysis was performed to determine the risk ratio for hospital LOS as well as complication rate, respectively. RESULTS: A total of 4,125 pediatric patients were identified. NHB cohort had a greater prevalence of cervical-only injuries (NHW: 37.39% vs. NHB: 49.93% vs. NHA: 34.29% vs. H: 38.71%, P < 0.001). While transport accident was most common injury etiology for both cohorts, NHB cohort had a greater prevalence of assault (NHW: 1.53% vs. NHB: 17.40% vs. NHA: 2.86% vs. H: 6.58%, P < 0.001) than the other cohorts. Overall complication rates were significantly higher among NHB patients (NHW: 9.39% vs. NHB: 15.12% vs. NHA: 14.29% vs. H: 13.60%, P < 0.001). Compared with the NHW cohort, NHB, NHA, and H had significantly longer hospital LOS (NHW: 6.15 ± 9.03 days vs. NHB: 9.24 ± 20.78 days vs. NHA: 9.09 ± 13.28 days vs. H: 8.05 ± 11.45 days, P < 0.001). NHB race was identified as a significant predictor of increased LOS on multivariate regression analysis (risk ratio: 1.14, 95% confidence interval: 0.46, 1.82; P = 0.001) but not hospital complications (P = 0.345). CONCLUSIONS: Race may significantly impact health care resource utilization following pediatric cervical/thoracic spinal trauma.

Feedback Frequency in Competence by Design: A Quality Improvement Initiative.

BACKGROUND: Otolaryngology-head and neck surgery is in the first wave of residency training programs in Canada to adopt Competence by Design (CBD), a model of competency-based medical education. CBD is built on frequent, low-stakes assessments and requires an increase in the number of feedback interactions. The University of Toronto otolaryngology-head and neck surgery residents piloted the CBD model but were completing only 1 assessment every 4 weeks, which was insufficient to support CBD. OBJECTIVE: This project aimed to increase assessment completion to once per resident per week using quality improvement methodology. METHODS: Stakeholder engagement activities had residents and faculty characterize barriers to assessment completion. Brief electronic assessment forms were completed by faculty on residents' personal mobile devices in face-to-face encounters, and the number completed per resident was tracked for 10 months during the 2016-2017 pilot year. Response to the intervention was analyzed using statistical process control charts. RESULTS: The first bundled intervention-a rule set dictating which clinical instance should be assessed, combined with a weekly reminder implemented for 10 weeks-was unsuccessful in increasing the frequency of assessments. The second intervention was a leaderboard, designed on an audit-and-feedback system, which sent weekly comparison e-mails of each resident's completion rate to all residents and the program director. The leaderboard demonstrated significant improvement from baseline over 10 weeks, increasing the assessment completion rate from 0.22 to 2.87 assessments per resident per week. CONCLUSIONS: A resident-designed audit-and-feedback leaderboard system improved the frequency of CBD assessment completion.

Clinical applications of three-dimensional printing in otolaryngology-head and neck surgery: A systematic review.

OBJECTIVES: Medical three-dimensional (3D) printing, the fabrication of handheld models from medical images, has the potential to become an integral part of otolaryngology-head and neck surgery (Oto-HNS) with broad impact across its subspecialties. We review the basic principles of this technology and provide a comprehensive summary of reported clinical applications in the field. METHODS: Standard bibliographic databases (MEDLINE, Embase, Cumulative Index to Nursing and Allied Health Literature, Web of Science, and The Cochrane Central Registry for Randomized Trials) were searched from their inception to May 2018 for the terms: "3D printing," "three-dimensional printing," "rapid prototyping," "additive manufacturing," "computer-aided design," "bioprinting," and "biofabrication" in various combinations with the terms: "ptolaryngology," "head and neck surgery," and "otology." Additional articles were identified from the references of retrieved articles. Only studies describing clinical applications of 3D printing were included. RESULTS: Of 5,532 records identified through database searching, 87 articles were included for qualitative synthesis. Widespread implementation of 3D printing in Oto-HNS is still at its infancy. Nonetheless, it is increasingly being utilized across all subspecialties from preoperative planning to design and fabrication of patient-specific implants and surgical guides. An emerging application considered highly valuable is its use as a teaching tool for medical education and surgical training. CONCLUSIONS: As technology and training standards evolve and as healthcare moves toward personalized medicine, 3D printing is emerging as a key technology in patient care in Oto-HNS. Treating physicians and surgeons who wish to stay abreast of these developments will benefit from a fundamental understanding of the principles and applications of this technology.

Multiple Eruptive Eccrine Poromas Associated with Chemotherapy and Autologous Bone Marrow Transplantation.

Eccrine poroma is a benign adnexal tumor that originates from the uppermost portion of the intraepidermal eccrine duct. It usually presents as a solitary tumor. Histopathology shows a monomorphic proliferation of cuboidal cells, which radially extend from the basal layer to the dermis. Here, we present a rare multilesional eruption of eccrine poroma after chemotherapy and bone marrow stem cell transplantation for acute promyelocytic leukemia along with a description of clinical, pathological, and dermoscopic findings.

Predictors of Unemployment After Breast Cancer Surgery: A Systematic Review and Meta-Analysis of Observational Studies.

Purpose Breast cancer surgery is associated with unemployment. Identifying high-risk patients could help inform strategies to promote return to work. We systematically reviewed observational studies to explore factors associated with unemployment after breast cancer surgery. Methods We searched MEDLINE, EMBASE, CINAHL, and PsycINFO to identify studies that explored risk factors for unemployment after breast cancer surgery. When possible, we pooled estimates of association for all independent variables reported by more than one study. Results Twenty-six studies (46,927 patients) reported the association of 127 variables with unemployment after breast cancer surgery. Access to universal health care was associated with higher rates of unemployment (26.6% v 15.4%; test of interaction P = .05). High-quality evidence showed that unemployment after breast cancer surgery was associated with high psychological job demands (odds ratio [OR], 4.26; 95% CI, 2.27 to 7.97), childlessness (OR, 1.30; 95% CI, 1.11 to 1.53), lower education level (OR, 1.15; 95% CI, 1.05 to 1.25), lower income level (OR, 1.46; 95% CI, 1.24 to 1.73), cancer stage II, III or IV (OR, 1.43; 95% CI, 1.13 to 1.82), and mastectomy versus breast-conserving surgery (OR, 1.18; 95% CI, 1.07 to 1.30). Moderate-quality evidence suggested an association with high physical job demands (OR, 2.11; 95%CI, 1.52 to 2.93), African-American ethnicity (OR, 1.89; 95% CI, 1.21 to 2.96), and receipt of chemotherapy (OR, 1.95; 95% CI, 1.36 to 2.79). High-quality evidence demonstrated no significant association with part-time hours, blue-collar work, tumor size, positive lymph nodes, or receipt of radiotherapy or endocrine therapy; moderate-quality evidence suggested no association with age, marital status, or axillary lymph node dissection. Conclusion Addressing high physical and psychological job demands may be important in reducing unemployment after breast cancer surgery.

Outpatient versus inpatient thyroidectomy: A systematic review and meta-analysis.

BACKGROUND: Outpatient thyroidectomy has gained popularity due to improved resource utilization. METHODS: We conducted a systematic review and meta-analysis using MEDLINE, EMBASE, CINAHL, Web of Science, and the Cochrane library. We included all studies examining the outcomes of outpatient thyroidectomy as compared with those of inpatient thyroidectomy. Risk of bias was assessed using the Newcastle-Ottawa scale. Postoperative complications (hematoma, hypocalcemia, and recurrent laryngeal nerve injury) and readmission/reintervention rates were compared. RESULTS: After screening 1665 records, 10 nonrandomized observational studies were included. There were fewer complication rates in the outpatient group than the inpatient group (relative risk [RR] 0.56; 95% confidence interval [CI] 0.37-0.83). There was no difference in readmission/reintervention rates (RR 0.60; 95% CI 0.33-1.09). CONCLUSION: The results suggest outpatient thyroidectomy may be as safe as inpatient thyroidectomy in appropriately selected patients. The results are limited by high risk of bias. Well-designed prospective studies are necessary to further assess the safety of outpatient thyroidectomy.

Congenital Trismus From Brainstem Dysgenesis: Case Report and Review of Literature.

Trismus refers to any condition inducing limited mouth opening and may present as a result of acquired or congenital pathology. We present the case of a newborn who presented with severe, congenital trismus due to brainstem dysgenesis. We describe the course of his investigations, and a multidisciplinary approach to the management of his care and follow-up. To our knowledge, this is one of the earliest reported cases of congenital trismus attributable to brainstem dysgenesis. A literature review was conducted to provide an overview of the differential pathogenesis as it presents in congenital cases and discuss the complexity of managing congenital trismus due to brainstem dysgenesis in a neonate and infant.

Changes in parvalbumin immunoreactive retinal ganglion cells and amacrine cells after optic nerve injury.

Parvalbumin (PARV) is a Ca(2+)-binding protein that may offer resistance to cell death as it primarily functions to maintain Ca(2+) homeostasis. The purpose of this study was to investigate whether PARV expressing retinal ganglion cells (RGCs) would be more resistant to cell death than RGCs that do not express PARV. RGCs in Sprague-Dawley rats were retrogradely labeled with Fluorogold (FG). After 2-28 days following an optic nerve crush (ONC) injury immunohistochemistry was performed on the sections using antibodies against PARV and markers of RGCs. The proportion of retinal ganglion cell layer cells labeled with PARV colocalized with FG or Brn3a and labeled only with PARV (displaced amacrine cells; dACs) were analyzed. PARV staining intensity was measured in ACs, dACs, and RGCs. Double labeling studies revealed that 49% of RGCs and 22% of dACs expressed PARV. There was an immediate reduction in RGC PARV staining after ONC but the overall rate of cell death after 28 days was similar in PARV and non-PARV expressing RGCs. There was no change in PARV AC or dAC number or staining intensity. Although this study suggests that there is no selective survival of the subpopulation of RGCs that contain PARV, there is down-regulation of PARV expression by these RGCs. This suggests that down-regulation of PARV may contribute to RGC death due to a compromised Ca(2+) buffering capacity. Maintaining PARV expression after injury could be an important neuroprotective strategy to improve RGC survival after injury.

Open versus endoscopic septoplasty techniques: A systematic review and meta-analysis.

BACKGROUND: Septal deviation is a condition of high prevalence, which ranges from 22% in newborns to 90% in adults. Surgical intervention is frequently considered in the management of patients with symptoms. Although many surgeons prefer either the endoscopic or the open approach to septoplasty, there is an ongoing debate regarding comparative outcomes between the two approaches. OBJECTIVE: The purpose of this study was to systematically review the literature and provide pooled summary estimates to evaluate the efficacy and safety of open versus endoscopic septoplasty techniques. METHODS: This study was registered with PROSPERO (CRD42014010730). MEDLINE, EMBASE, Google Scholar, CINAHL, Web of Science, and The Cochrane Central Registry for Randomized Trials were searched for relevant studies by using the following keywords in varying combinations: "nasal septum," "nasal obstruction," "nasal cartilages," "nose," "nose diseases," "surgery," "nasal/septal deviation," and "septoplasty." All the studies that compared open versus endoscopic septoplasty techniques for the management of symptomatic septal deviation were considered. Two reviewers independently extracted data by using a preestablished extraction form and performed quality assessment by using the Jadad and Newcastle Ottawa Scales. Weighted pooled estimates were calculated and reported, along with relative risks and 95% confidence intervals. RESULTS: Fourteen studies met our inclusion criteria. When comparing open versus endoscopic septoplasty techniques, there was significant improvement in postoperative symptoms (i.e., nasal obstruction, headaches) (p < 0.05) in the endoscopic septoplasty group. There also were significantly fewer complications associated with the endoscopic septoplasty technique (p < 0.05). Based on the quality assessment, included studies were deemed at a moderate-to-high risk of bias. CONCLUSION: Our analysis indicated that endoscopic septoplasty may have some advantages over open septoplasty. However, our findings should be taken with caution given the poor quality of included studies.

Anti-IgE monoclonal antibody therapy for the treatment of chronic rhinosinusitis: a systematic review.

BACKGROUND: Several options are available for the treatment of chronic rhinosinusitis (CRS), but disease control remains elusive for many patients. Recently, literature has emerged describing anti-IgE monoclonal antibody as a potential therapy for CRS. However, its effectiveness and safety are not well known. The purpose of this systematic review was to assess the effectiveness and safety of anti-IgE therapy and to identify evidence gaps that will guide future research for the management of CRS. METHODS: Methodology was registered with PROSPERO (No. CRD42014007600). A comprehensive search was performed of standard bibliographic databases, Google Scholar, and clinical trials registries. Only randomized controlled trials assessing anti-IgE therapy in adult patients for the treatment of CRS were included. Two independent reviewers extracted data using a pre-defined extraction form and performed quality assessment using the Cochrane risk of bias tool and the GRADE framework. RESULTS: Two studies met our inclusion criteria. When comparing anti-IgE therapy to placebo, there was a significant difference in Lund-McKay score (p = 0.04) while no difference was seen for percent opacification on computed tomography (CT). At 16 weeks, treatment led to a decrease in clinical polyp score. No significant difference was seen with regard to quality of life (Total Nasal Symptom Severity (TNSS), p < 0.21; Sinonasal Outcome Test 20 (SNOT-20), p < 0.60), and no serious complications were reported in either trial. Based on the quality assessment, studies were deemed to be of moderate risk of bias and a low overall quality of evidence. CONCLUSIONS: There is currently insufficient evidence to determine the effectiveness of anti-IgE monoclonal antibody therapy for the treatment of CRS.

Treatment of posthemorrhagic ventricular dilation in preterm infants: a systematic review and meta-analysis of outcomes and complications.

OBJECT The optimal clinical management of intraventricular hemorrhage (IVH) and posthemorrhagic ventricular dilation (PHVD)/posthemorrhagic hydrocephalus (PHH) in premature infants remains unclear. A common approach involves temporary treatment of hydrocephalus in these patients with a ventriculosubgaleal shunt (VSGS), ventricular access device (VAD), or external ventricular drain (EVD) until it becomes evident that the patient needs and can tolerate permanent CSF diversion (i.e., ventriculoperitoneal shunt). The present systematic review and meta-analysis aimed to provide a robust and comprehensive summary of the published literature regarding the clinical outcomes and complications of these 3 techniques as temporizing measures in the management of prematurity-related PHVD/PHH. METHODS The authors searched MEDLINE, EMBASE, CINAHL, Google Scholar, and the Cochrane Library for studies published through December 2013 on the use of VSGSs, VADs, and/or EVDs as temporizing devices for the treatment of hydrocephalus following IVH in the premature neonate. Data pertaining to patient demographic data, study methods, interventions, and outcomes were extracted from eligible articles. For each of the 3 types of temporizing device, the authors performed meta-analyses examining 6 outcomes of interest, which were rates of 1) obstruction; 2) infection; 3) arrest of hydrocephalus (i.e., permanent shunt independence); 4) mortality; 5) good neurodevelopmental outcome; and 6) revision. RESULTS Thirty-nine studies, representing 1502 patients, met eligibility criteria. All of the included articles were observational studies; 36 were retrospective and 3 were prospective designs. Nine studies (n = 295) examined VSGSs, 24 (n = 962) VADs, and 9 (n = 245) EVDs. Pooled rates of outcome for VSGS, VAD, and EVD, respectively, were 9.6%, 7.3%, and 6.8% for obstruction; 9.2%, 9.5%, and 6.7% for infection; 12.2%, 10.8%, and 47.3% for revision; 13.9%, 17.5%, and 31.8% for arrest of hydrocephalus; 12.1%, 15.3%, and 19.1% for death; and 58.7%, 50.1%, and 56.1% for good neurodevelopmental outcome. CONCLUSIONS This study provides robust estimates of outcomes for the most common temporizing treatments for IVH in premature infants. With few exceptions, the range of outcomes was similar for VSGS, VAD, and EVD.

Duplicate publication in radiology journals.

OBJECTIVE: The purpose of this study is to evaluate the rate of duplicate publication in radiology journals. The secondary objective is to evaluate the sensitivity of iThenticate. MATERIALS AND METHODS: From January 1993 to December 2013, Déjà Vu (a database of highly similar citations) and PubMed were used to search for similar citations in 53 radiology journals. Citations were screened independently by two reviewers and verified by a third using predefined criteria to determine true cases of duplicate publication. The overall rate of duplicate publication was calculated; analysis of rate by journal, impact factor, and publication year was performed. The sensitivity of iThenticate was evaluated by analyzing all identified duplicate publications. RESULTS: From 128,818 citations in the included journals, 1786 (Déjà Vu) and 104 (PubMed) were flagged as potential duplicates. Of these, 248 (226 from Déjà Vu and 22 from PubMed) were classified as true duplicate publications after application of our criteria. The overall rate was 1.92/1000 citations; it varied widely across journals from zero to over 10/1000 citations, showed no correlation with impact factor (R(2) = 0.06; p = 0.093), and no change over time (R(2) = 0.28; p = 0.515). iThenticate flagged 153 of 248 (61.9%) duplicates as "possible duplicates" (defined as overall percentage match > 30%) and identified the corresponding duplicate citation pair in 140 of 248 (56.7%) cases; in 98 of these, the duplicate citation pair was the highest percentage similarity match. CONCLUSION: Duplicate publications in radiology journals are uncommon. The rate varies widely between journals, but was not associated with journal impact factor and did not change over time. iThenticate shows promise for identification of duplicate publications; however, refinements may be necessary to maximize its effectiveness.

Accuracy and completeness of electronic medical records obtained from referring physicians in a Hamilton, Ontario, plastic surgery practice: A prospective feasibility study.

OBJECTIVE: To assess the feasibility of auditing electronic medical records (EMRs) in plastic surgery for future large-scale research studies. The secondary objective was to ascertain the accuracy and completeness of EMRs accompanying referral requests by physicians for plastic surgery consultation between July and December 2013. METHODS: EMRs of 30 patients were reviewed and crosschecked independently by two reviewers and subsequently verified by a third reviewer using predefined criteria to determine whether they were accurate and/or complete. Descriptive analysis was performed to calculate the frequency of inaccuracies and incompleteness for each EMR information field. Information fields were compared to assess whether the frequency of inaccuracies and incompleteness varied. RESULTS: Of the 270 information fields reviewed, four (1.48%) were inaccurate and 66 (24.4%) were incomplete. The most common field of inaccuracy was current medications, followed by medical history and medical allergies. The most common field of incompleteness was history of presenting illness followed by surgical history. CONCLUSION: Despite their purported benefits, inaccuracies and incompleteness are a frequently occurring problem in EMRs. A large-scale study may be beneficial in determining the efficacy of EMRs in the future.

OBJECTIF: Évaluer la faisabilité de vérifier les dossiers médicaux électroniques (DMÉ) en chirurgie plastique en vue de futurs projets de recherche à grande échelle. L'objectif secondaire visait à établir l'exactitude et l'exhaustivité des DMÉ accompagnant les demandes d'aiguillage de médecins vers une consultation en chirurgie plastique entre juillet et décembre 2013. MÉTHODOLOGIE: Deux réviseurs, suivis d'un troisième, ont examiné et contre-vérifié les DMÉ de 30 patients de manière indépendante au moyen de critères prédéfinis pour déterminer s'ils étaient exacts ou complets. Ils ont effectué une analyse descriptive pour calculer la fréquence d'inexactitudes et d'omissions dans chaque champ d'information des DMÉ. Ils ont comparé les champs d'information pour évaluer la variation de la fréquence d'inexactitudes et d'omissions. RÉSULTATS: Sur les 270 champs d'information examinés, quatre (1,48 %) étaient inexacts et 66 (24,4 %), incomplets. Le champ grevé du plus d'inexactitudes était les médicaments actuels, suivi des antécédents médicaux et des allergies médicales. Le champ le plus souvent incomplet était l'histoire des symptômes initiaux, suivi des antécédents chirurgicaux. CONCLUSION: Malgré les prétendus avantages des DMÉ, les inexactitudes et les omissions sont fréquentes. Une étude à grande échelle pourrait contribuer à déterminer l'efficacité des DMÉ.

Methodological guide to adopting new aesthetic surgical innovations.

Aesthetic surgery is known for its prolific introduction of new techniques, devices, and products. The implementation of any aesthetic innovation, however, may inadvertently expose patients to potential complications and adverse events. How do we decide whether a new technique or technology is superior-in both safety and effectiveness-compared with prevailing interventions? In this paper, we present some basic steps anchored in evidence-based surgery that aesthetic surgeons need to pursue in the adoption of a new technique, technology, or product. These steps include: (1) gaining familiarity with and understanding the levels of evidence; (2) performing an effective literature search; (3) formulating a critical appraisal of an article; (4) making the decision to adopt or reject; (5) recognizing the need for continued assessment; (6) acknowledging the need for education and credentialing; and (7) translation of the gathered knowledge. We hope that this paper will foster critical thinking and reduce the reliance on "photographic evidence" in aesthetic surgery literature.

3D printed ventricular septal defect patch: a primer for the 2015 Radiological Society of North America (RSNA) hands-on course in 3D printing.

Hand-held three dimensional models of the human anatomy and pathology, tailored-made protheses, and custom-designed implants can be derived from imaging modalities, most commonly Computed Tomography (CT). However, standard DICOM format images cannot be 3D printed; instead, additional image post-processing is required to transform the anatomy of interest into Standard Tessellation Language (STL) format is needed. This conversion, and the subsequent 3D printing of the STL file, requires a series of steps. Initial post-processing involves the segmentation-demarcation of the desired for 3D printing parts and creating of an initial STL file. Then, Computer Aided Design (CAD) software is used, particularly for wrapping, smoothing and trimming. Devices and implants that can also be 3D printed, can be designed using this software environment. The purpose of this article is to provide a tutorial on 3D Printing with the test case of complex congenital heart disease (CHD). While the infant was born with double outlet right ventricle (DORV), this hands-on guide to be featured at the 2015 annual meeting of the Radiological Society of North America Hands-on Course in 3D Printing focused on the additional finding of a ventricular septal defect (VSD). The process of segmenting the heart chambers and the great vessels will be followed by optimization of the model using CAD software. A virtual patch that accurately matches the patient's VSD will be designed and both models will be prepared for 3D printing.
