RESUMEN

In the field of addictology, care integrates activities that reactivate forgotten senses, emotions and postures. A "Photographs" workshop, led by a nurse in the addictology department, was modulated into a "Brief group photo-motivational intervention" to help people quit smoking. From this experience emerged an educational sequence of "Photo-Expression" integrated into the patient's therapeutic education programme "Help to stop smoking".

RESUMEN

OBJECTIVE: To explore the possibility of the Smile Lite MDP (Smile Lite Mobile Dental Photograph) portable dental photography system applying in anterior teeth aesthetic photography, and to provide the chance to simplify aesthetic photography process and facilitate communication among patients, dentists and dental technitians. METHODS: The Smile Lite MDP photography system combined with the smartphone were used to photograph the front occlusal phase photos of anterior teeth. The photographic conditions including the color temperature parameter, the Smile Lite MDP light position and the intensity settings were explored. The best photographic conditions were chosen by blind evaluation within experienced dentists and technicians through the method of the visual analogue scale/score (VAS) evaluation, which went through statistical analysis to figure out the optimum photograghic conditions. Smile Lite MDP photography system was used to photograph the front occlusal phase photos of anterior teeth under the optimum parameter by different magnifications. The width/height ratio of the central incisor and the front width ratio of the upper anterior teeth in those photos were measured and calculated respectively. The accuracy of the anterior teeth photos taken by Smile Lite MDP photography system was analyzed based on the photographs taken by digital single lens reflex (DSLR) camera. RESULTS: The optimum color temperature parameter of Smile Lite MDP portable camera system was 5 000 K, the optimum magnification was 4 times, the best light position was the side lights of Smile Lite MDP, the optimum intensity of lights was 2 grades. Photos taken by the optimum parameters won the highest score during the VAS evaluation and the result of statistical analysis had significant difference compared with other groups (P<0.05). When comparing the photos of the upper anterior teeth taken by the Smile Lite MDP portable photography system using 4 times magnification or by DSLR using the standard parameters, there was no significant difference neither in the width/hieght ratio of the central incisor nor in the front width ratio of the upper anterior teeth (P>0.05). CONCLUSION: The Smile Lite MDP portable dental photography system applying in anterior teeth aesthetic analysis photography was capable to show the color and shape of anterior teeth in an accurate way by using the right photography parameters. Therefore, Smile Lite MDP portable dental photography system was considered to be a simple and easy photographic tool in clinical work.

RESUMEN

INTRODUCTION: Dermatofibrosarcoma (DFS) is a common dermic sarcoma. It is a local malignant tumor occurring in young adults. The recurrence potential justifies an R0-type surgery with a three centimeters margin. We report our experience of the management of locally advanced DFS by resection and reconstructive surgery. METHODS: It is an ongoing descriptive study spanned from June 2005 to December 2018. We included all DFS cases treated by curative resection and reconstruction. A total of eight cases of DFS among 108 soft tissue sarcomas were studied. All patients were males. The mean age was 41.8 years [32-60]. Carcinologic results, cosmetic results, and outcomes were analyzed. RESULTS: R0-type resection was performed in six cases. In two cases, the resection was R1-type and resulted in amputation. In four cases, it was an iterative surgery. Average desease duration was 4 years [1-8]. Reconstructive surgery was needed for wound closure in six cases. Wounds healed in 28 days [18-90]. Outcomes showed hyperchromic keloid scars (N=2) at the trunk localization. CONCLUSION: DFS is a common cancer with a good outcome if managed earliest. Delayed diagnoses and inadequate first-time surgery led to tumor extension and recurrences. Locally advanced tumors management needs extensive resections and reconstructive surgery. In addition to surgery, Imatinib and radiotherapy improve outcomes, but are not available in our context.

RESUMEN

BACKGROUND: The incidence of taking selfies and sharing them on social media as well as selfie-related dangerous behaviors is increasing, particularly among young people, also leading to selfie-related trauma and death. This study was performed to obtain epidemiological characteristics of selfie-related mortality in Italy. METHODS: Scientific literature and Italian media were reviewed. RESULTS: Twelve victims from 11 events, from 2014 to 2018, were analyzed (sex, age, accident types, the nationality, the Italian region where the incident took place, if the person involved was indigenous or a tourist, the dynamics and the causa mortis, if other people have been involved in the selfie, and if other people were deceased). The majority of selfie victims were male teenagers, the average age was 23.6 years, the most preferred site of taking selfies was the natural environment followed by the railway one, the most frequently reported event or accident type was falling from a height, and the most frequent causes of selfie-related deaths were multitrauma and drowning. CONCLUSIONS: Selfie-related deaths in Italy appear to be an issue and appear to be increasing. Particularly, male teenagers and young adults are at high risk for selfie-related deaths. Measures should be taken to reduce their incidence.

RESUMEN

OBJECTIVE: To manage three cases of mild to moderate fluorosis by resin infiltration technique and to quantify the tooth color changes by measuring CIE L*a*b* values of digital photographs and calculating ΔE00 based on the CIEDE2000 formula using Adobe Photoshop software. METHODS AND MATERIALS: Three cases of mild to moderate fluorosis were treated with a combination of bleaching and a resin infiltration technique. CIE L*a*b* values of 18 fluorosed spots were measured from digital photographs of these cases at four different stages-preoperative, postbleaching, postinfiltration and at 12-month follow-up-using Adobe Photoshop software, and ΔE00 was calculated based on the CIEDE2000 formula. The ΔE00 values of all 18 points obtained at different stages were submitted to statistical analysis (α=0.05). RESULTS: In all the cases reported, clinically as well as by the photographic color analysis, it was found that the technique masked the lesions, improving the patients' esthetics, which was maintained even at 12-month recall. Statistically significant difference in ΔE00 values was present between comparison of all stages (p<0.001) except between postinfiltration and the 12-month follow-up stage (p=0.642). CONCLUSION: A resin infiltration technique helped in the satisfactory management of white spot lesions of fluorosis, which were stable even at 12-month follow up. Quantitation of the changes was achieved using Adobe Photoshop software.

RESUMEN

PURPOSE: The purpose of this study was to determine the longitudinal effects of feedback involving photography and self-assessment on the accuracy of ergonomic self-assessments and ergonomic scores amongst dental hygiene students. MATERIALS AND METHODS: The study involved an experimental design. Data collection took place over 4 months, divided into weeks 1-4 and after 3 months. At weeks 1 through 4 and 3 months, all participants completed ergonomic self-evaluations, using a Modified-Dental Operator Posture Assessment Instrument. At week 1, week 4 and 3 months, all participants were photographed, and in weeks 2 and 3, only participants in the training group were photographed and used those photographs to complete ergonomic self-assessments. All participants' photographs were evaluated by three faculty raters. RESULTS: A mixed-design ANOVA of Kappa coefficient values between student and rater scores measured the effects of the feedback with photography on the accuracy of student self-assessments. A main effect for group was not found to be significant (F(1,30) = 2.90, P = .101). A mixed-design ANOVA measured the effects of the feedback with photography on the ergonomic scores. No significant main effects were found (F(1,120) = 1.55, P = .216). CONCLUSION: Although self-assessment utilising photographs resulted in initial improvements in the accuracy of ergonomic self-assessments and ergonomic scores after 4 weeks, both ergonomic accuracy and scores significantly decreased after 3 months. Improvement in ergonomic accuracy and scores may be sustained by the continual facilitated use of photographs and self-assessment by dental and dental hygiene educators.

RESUMEN

PURPOSE: Our purpose was to report the feasibility and safety of diffusing alpha-emitter radiation therapy (DaRT), which entails the interstitial implantation of a novel alpha-emitting brachytherapy source, for the treatment of locally advanced and recurrent squamous cancers of the skin and head and neck. METHODS AND MATERIALS: This prospective first-in-human, multicenter clinical study evaluated 31 lesions in 28 patients. The primary objective was to determine the feasibility and safety of this approach, and the secondary objectives were to evaluate the initial tumor response and local progression-free survival. Eligibility criteria included all patients with biopsy-proven squamous cancers of the skin and head and neck with either primary tumors or recurrent/previously treated disease by either surgery or prior external beam radiation therapy; 13 of 31 lesions (42%) had received prior radiation therapy. Toxicity was evaluated according to the Common Terminology Criteria for Adverse Events version 4.03. Tumor response was assessed at 30 to 45 days at a follow-up visit using the Response Evaluation Criteria in Solid Tumors, version 1.1. Median follow-up time was 6.7 months. RESULTS: Acute toxicity included mostly local pain and erythema at the implantation site followed by swelling and mild skin ulceration. For pain and grade 2 skin ulcerations, 90% of patients had resolution within 3 to 5 weeks. Complete response to the Ra-224 DaRT treatment was observed in 22 lesions (22/28; 78.6%); 6 lesions (6/28, 21.4%) manifested a partial response (>30% tumor reduction). Among the 22 lesions with a complete response, 5 (22%) developed a subsequent local relapse at the site of DaRT implantation at a median time of 4.9 months (range, 2.43-5.52 months). The 1-year local progression-free survival probability at the implanted site was 44% overall (confidence interval [CI], 20.3%-64.3%) and 60% (95% CI, 28.61%-81.35%) for complete responders. Overall survival rates at 12 months post-DaRT implantation were 75% (95% CI, 46.14%-89.99%) among all patients and 93% (95% CI, 59.08%-98.96%) among complete responders. CONCLUSIONS: Alpha-emitter brachytherapy using DaRT achieved significant tumor responses without grade 3 or higher toxicities observed. Longer follow-up observations and larger studies are underway to validate these findings.

RESUMEN

In 1949, the American Graves Registration Service Pacific Zone proposed the identification of 27 sets of remains (skulls/crania/mandibles) based on comparisons with written dental records. All were denied, and the remains were buried as unknowns. In 2003 and 2015, the remains were exhumed by the DPAA. Currently, 26 individuals previously recommended for identification have been positively identified. The DPAA Science Director's opinion corresponded with 24 of their recommendations, while DNA excluded three. Caution should be taken by the forensic scientist when building assemblages through skeletal and dental articulation. The forensic odontologist must always consider variations in restorative care/extraction patterns and the possibility of documentation errors when reviewing/interpreting historical and current day dental records used for AM/PM comparisons. The odontologist should base their opinion on the strength of the antemortem/postmortem comparison, number and type of concordances, and distinct dental care and extraction patterns.

RESUMEN

This article addresses the use of photographic comparison as a complementary visual appraisal method in an outdoor thermal perception survey. This survey was carried out during a Ph.D. research exploring how materials and vegetation influence thermal comfort in outdoor public spaces. Objective and subjective thermal perception parameters were combined and quantitative and qualitative research methods were used. The quantitative methods included microclimatic measurements, whilst the qualitative methods comprised observations and spatially localised interviews based on a questionnaire and the photographic comparison. This article explores how such visual research method allowed triangulating findings of this field survey. Three non-edited photographs of outdoor public spaces, under similar summer meteorological conditions but with contrasting spatial features, were shown to respondents to the questionnaire. The photographs depicted undisclosed locations for preventing biased emotional appreciations. Respondents were asked to select the potentially most comfortable and uncomfortable environments depicted. The choice of photographs matched the previous answers on the thermal sensation and evaluation judgement scales. Hence, we discuss the way the visual interpretations by respondents allowed the triangulation of in situ thermal perception data. The extent to which thermal comfort can be interpreted from thermal environments depicted in photographs containing clear visual signs is further discussed. The article concludes on how such a visual appraisal method can be valuable for enriching future qualitative outdoor thermal perception surveys with subjective interpretation of visual data.

RESUMEN

PURPOSE: The aim of this study is to assess the agreement between manual and automated gonioscopy for iridocorneal angle opening. METHODS: The research is a cross-sectional observational study. Manual and automated gonioscopy were performed to consecutive patients in a glaucoma clinic. Iridocorneal angle opening grading was performed according to Shaffer's classification. Automated gonioscopy was performed with NGS-1 automated gonioscope (NIDEK Co., Gamagori, Japan). The automated gonio-photos were graded by two independent observers. Agreement between automated and manual gonioscopy and also among raters was ascertained by Fleiss' kappa statistic and comparison of area under curve. RESULTS: In total, 88 eyes of 47 subjects were analysed. Mean age was 63 ± 10 years. Twenty eyes (22.7%) were excluded from grading due to poor quality images. Angle closure was detected in 23.4% with dynamic gonioscopy in comparison with 4.3% using automated image grading. The agreement for angle closure diagnosis between dynamic and automated gonioscopy was low (κ = 0.09 ± 0.10; p = 0.18). The area under curve for detecting eyes with angle closure showed poor accuracy between automated and manual methods (area under curve: 0.53 ± 0.05, 95% confidence interval: 0.44-0.62). There was modest inter-rater agreement for angle opening assessment of automated images with Fleiss' kappa of 0.17 (95% confidence interval: 0.035-0.238). CONCLUSION: Manual and automated gonioscopy showed only slight agreement for the assessment of iridocorneal angle opening status. Further improvements of the NGS-1 automated gonioscopy and technique are desired for widespread use in a real-life setting.

RESUMEN

BACKGROUND: The need for a better understanding of the subthalamic nucleus (STN)'s vascular anatomy is still evident because revealing its vascular supply may increase insight in the pathogenesis of related disorders, such as STN ischemia. The mechanisms under motor, behavioral, and cognitive changes following deep brain stimulation treatment may also be explained by its pattern of vascularization. The primary goal of this study was to delineate the vascularization of the STN and highlight the predominant perforating arteries supplying its territory. METHODS: Fiber dissections were performed with the modified Klingler technique under 6-40× magnification by preserving all vascular structures. RESULTS: The thalamic and subthalamic regions were dissected from medial to lateral in silicone-injected cadavers. The STN was revealed as a biconvex-shaped structure surrounded by dense inferolateral bundles of myelinated fibers, the zona incerta, bordering the superolateral portion of the red nucleus. The ventral limit of the STN was the substantia nigra, and the internal capsule traversed from its inferior to anterolateral side. The premamillary artery, a large perforator arising from the posterior communicating artery, constantly supplied the STN and was followed proximally along the anterior third ventricular floor toward its origin. The premamillary artery was found to be one of the posterior perforators of the posterior communicating artery in all hemispheres. CONCLUSIONS: The 3-dimensional microsurgical anatomy of the deep-seated STN region is complex, and the additional knowledge on its vascularization should improve our understanding of its surgical anatomy.

RESUMEN

AIMS AND OBJECTIVES: To explore palliative care nurses' work experiences caring for patients at the end of life in private homes. BACKGROUND: The home continues to be a desired place for care and dying; however, professional competence is needed and specialist palliative care nurses play a crucial role, often highly valued by patients and their family members. The private home as a physical work environment for nurses is explored, with both positive and negative aspects being described. To ensure future high-quality end-of-life care, there is a need to describe how palliative care nurses work in private homes. DESIGN: Interpretative descriptive. METHODS: Participant-generated photographs were used in conjunction with follow-up interviews with ten palliative home care nurses. Interpretive description was used for analysis. This study follows the COREQ checklist. RESULTS: The analysis process resulted in four constructed themes, presented here as strategies used by palliative care nurses: adjusting interactions and actions depending on the environment when entering each unique private home; supporting patients and family members in finding a balance between self-care, independence and safe care; guiding patients and family members towards and through environmental changes supporting end-of-life care at home; and using transitions between homes to reflect, recuperate and prepare. CONCLUSION: Working as a palliative care nurse in private homes clearly requires a variety of skills and competences, here operationalised in different strategies used to promote high-quality care. RELEVANCE TO CLINICAL PRACTICE: Palliative care nurses' considerations, insights and competence when performing end-of-life care in the diverse environments of private homes can contribute to the development of clinical practice. Knowledge about strategies can be used in nursing practice during everyday work, in nursing education and in the organisation of care, and can inform policy to ensure future high-quality palliative home care.

RESUMEN

Systems for instrumented motion analysis depend on an accurate biomechanical model. In this work an existing statistical shape fitting approach was adapted to register a parametrized human surface model with annotated anatomical landmarks to a point cloud obtained from one frontal depth camera view. Based on the obtained landmark positions joint centers, segment lengths and segment orientations of the lower body were calculated. The outcome was validated among two groups of healthy and impaired subjects, using a marker-based optical motion capture system. The results reveal a valid and reliable approach for obtaining an individualized lower body biomechanical model with minimum effort.

RESUMEN

OBJECTIVE: To evaluate indications, results and strategy of retinal exams requested at Primary Care Units. METHODS: A retrospective study that analyzed the indications and results of retinal exams, in the modalities clinical dilated fundus exams and color fundus photographs. In the following situations, patients were considered eligible for color fundus photographs if visual acuity was normal and ocular symptoms were absent: diabetes mellitus and/or hypertension, in use of drugs with potential retinal toxicity, diagnosis or suspicion of glaucoma, stable and asymptomatic retinopathies, except myopia greater than -3.00 diopters. RESULTS: A total of 1,729 patients were evaluated (66% female, age 63.5±15.5 years), and 1,190 underwent clinical dilated fundus exam and 539 underwent color fundus photographs. Diabetes was present in 32.2%. The main indications were diabetes (23.7%) and glaucoma evaluation (23.5%). In 3.4% of patients there was no apparent indication. The main results were a large cup/disc ratio (30.7%) and diabetic retinopathy (13.2%). Exam was normal in 9.6%, detected peripheral changes in 7% and could not be performed in 1%. Considering patients eligible for fundus photographs (22.4%), more than half underwent clinical dilated fundus exams. CONCLUSION: Regarding exam modality, there were no important differences in the distribution of indications or diagnosis. Color fundus photograph is compatible with telemedicine and more cost-effective, and could be considered the strategy of choice in some scenarios. Since there are no clear guidelines for retinal exams indications or the modality of choice, this study may contribute to such standardization, in order to optimize public health resources.

RESUMEN

Velocity-based training (VBT) requires the monitoring of lift velocity plus the prescribed resistance weight. A validated and reliable device is needed to capture the velocity and power of several exercises. OBJECTIVES: The study objectives were to examine the validity and reliability of the Elite Form Training System® (EFTS) for measures of peak velocity (PV), average velocity (AV), peak power (PP), and average power (AP). DESIGN: Validity of the EFTS was assessed by comparing measurements simultaneously obtained via the Qualisys Track Manager software (C-motion, version 3.90.21, Gothenburg, Sweden) utilizing 6 motion capture cameras (Oqus 400, 240 Hz, Gothenburg, Sweden). METHODS: Six participants performed 6 resistance exercises in 2 sessions: power clean, dead lift, bench press, back squat, front squat, and jump squat. RESULTS: Simple Pearson correlations indicated the validity of the device (0.982, 0.971, 0.973, and 0.982 for PV, AV, PP, and AP respectively) and ranged from 0.868 to 0.998 for the 6 exercises. The test-retest reliability of the EFTS was shown by lack of significant change in the Pearson correlation (<0.3% for each variable) between the 2 sessions. The multiple count error rate was 2.0% and the missed count error rate was 2.1%. CONCLUSIONS: The validity and reliability of the EFTS were classified as excellent across all variables and exercises with only one exercise showing a slight influence by the velocity of the movement.

RESUMEN

OBJECTIVES: Previous studies comparing shoes based on the amount of midsole cushioning have generally used shoes from multiple manufacturers, where factors outside of stack height may contribute to observed biomechanical differences in running mechanics between shoes. Therefore, the purpose of this study was to compare ground reaction forces and ankle kinematics during running between three shoes (maximal, traditional, and minimal) from the same manufacturer that only varied in stack height. DESIGN: Within-participant repeated measures METHODS: Twenty recreational runners ran overground in the laboratory in three shoe conditions (maximal, traditional, minimal) while three-dimensional kinematic and kinetic data were collected using a 3D motion capture system and two embedded force plates. Repeated measures ANOVAs (α=.05) compared biomechanical data between shoes. RESULTS: While the loading rate was significantly greater in the minimal shoe compared to the maximal shoe, no other differences were seen for the ground reaction force variables. Peak eversion was greater in the maximal and minimal shoe compared to the traditional shoe, while eversion duration and eversion at toe-off were greater in the maximal shoe. CONCLUSIONS: Previously cited differences in ground reaction force parameters between maximal and traditional footwear may be due to factors outside of midsole stack height. The eversion mechanics in the maximal shoes from this study may place runners at a greater risk of injury. Disagreement between previous studies indicates that more research on maximal running shoes is needed.

RESUMEN

After the Great East Japan Earthquake and Tsunami, volunteers participated in the recovery of lost photographs. This effort-which we call the Picturescue Movement-subsequently began to organise photograph restoration gatherings. We conducted field research during the gatherings in Noda, one of the tsunami-stricken areas. We have also carried out research on restoration gatherings in the city of Rikuzentakata. A comparison of findings across these two localities identifies two approaches to photograph restoration gatherings: 'aiming' and 'staying'. The aiming approach, employed in Rikuzentakata, emphasises returning photographs to their owners quickly, whereas the latter approach, used in Noda, is one in which volunteers stay with survivors for some time and encourage them to recall the past at their own pace. We conclude that the staying approach is more likely than the aiming approach to promote disaster recovery among survivors.
