RESUMO
Objective: Dental caries remains a prevalent disease worldwide. Several epidemiological studies have shown that it affects the oral health of the pediatric population, and the Galapagos population in Ecuador is no exception. The aim of this study was to determine the prevalence of dental caries and its association, based on baseline information from the Galapagos Oral Health Study (ESSO-Gal), in children of the Galapagos Islands, Ecuador. Methods: A cross-sectional study was conducted involving 804 children aged 2-11 years. The prevalence of dental caries was assessed using the International Caries Detection and Assessment System (ICDAS II) criteria, while the presence of dental biofilm was assessed using the Silness-Löe index. Descriptive statistics, including frequency analysis and measures of central tendency and dispersion, were performed. Inferential statistical analyses were conducted to identify associations between variables. Statistical analyses were performed using the SPSS version 25.0 statistical program. Results: The caries prevalence rates based on ICDAS II codes 1-6, 1-2, and 3-6 were 98.01%, 96.9%, and 85%, respectively. A statistically significant difference was observed among the different islands regarding the cutoff point for ICDAS II codes 3-6 (p ≤ 0.001). Participants aged 6-11 years had the highest caries prevalence. Conclusions: The results show a high prevalence of dental caries among children in the Galapagos Islands, which increases with age. Contrary to expectations, the study did not find a significant correlation between the severity of dental caries and the presence of dental biofilm.
RESUMO
BACKGROUND: With the spread of the COVID-19 virus, containment measures such as home confinement were implemented, generating stress, anxiety, depression and aggravation of pre-existing diseases in the population, including dentists, who have also been affected due to the risk involved in practicing their profession. Objective: To determine the impact of mandatory social isolation measures on the subjective well-being of Latin American and Caribbean dentists during the community quarantine due to the COVID-19 pandemic in 2020. MATERIAL AND METHODS: A Cross-sectional study in a sample of 1195 dentists from 21 countries in Latin America and the Caribbean. The main outcome was Subjective Well-Being, evaluated through the World Health Organization Well-Being Index (WHO-5). In addition, sociodemographic characteristics, variables related to the community quarantine due to the COVID-19 pandemic and health variables were considered. A descriptive, bivariate and multivariate (multiple linear regression) analysis was performed to observe the behavior of the variables. RESULTS: A multiple linear regression analysis was performed, where all the variables included within dimensions, were distributed in a single model, observing an R2% of 9.000 (p<0.001), where the R2% change was significant (p<0.001) and a constant of 44.190; likewise, within this model, the variable follow-up of preventive measures against COVID-19 reported an unstandardized regression coefficient (b) of 2. 316 (95%CI:1.133-3.499;p<0.001), the self-perceived level of concern against COVID-19 obtained a (b) of -5.470 (95%CI:-7.509--3.430; p<0.001), the biological sex variable manifested a (b) of -5.417 (95%CI: - 1.157-1.910; p<0.001); finally, the level of economic income during compulsory social isolation presented a (b)=5.354 (CI95%:3.461- 7.247; p<0.001). CONCLUSIONS: An association was found between subjective well-being and variables related to the social impact of the COVID-19 pandemic, such as following preventive measures, concern about the pandemic and economic factors (decrease in income level), in addition to biologic sex. Follow-up strategies are required for these dental professionals, considering that social isolation measures have continued in many of the countries.

RESUMO
INTRODUCTION: Dental caries have been traditionally managed with the non-selective removal of carious tissue (total removal). However, the adverse effects and fear that this technique produces in patients has promoted the use of more conservative caries removal techniques such as chemo-mechanical removal, but there is still controversy regarding its effectiveness and safety. METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings tables using the GRADE approach. RESULTS AND CONCLUSIONS: We identified seven systematic reviews including 34 studies overall, of which 30 correspond to randomized trials. We concluded that chemo-mechanical caries removal probably reduces the need for anesthesia. Additionally, chemo-mechanical caries removal may decrease the pain experienced by the patient, decrease the risk of restoration failure and increase the time of the procedure for the removal of deep caries, but the certainty of the evidence is low. We are uncertain whether chemo-mechanical caries removal reduces the risk of pulp exposure as the certainty of the evidence has been assessed as very low.
INTRODUCCION: La caries dental tradicionalmente es manejada con la remoción no selectiva del tejido carioso (remoción total). Sin embargo, los efectos adversos y el temor que produce esta técnica en los pacientes ha promovido la utilización de técnicas de remoción de caries más conservadoras como la remoción químico-mecánica, pero aún existe controversia respecto a su efectividad y seguridad. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane Library, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos siete revisiones sistemáticas que en conjunto incluyeron 34 estudios primarios, de los cuales 30 corresponden a ensayos aleatorizados. Concluimos que la remoción químico-mecánica de caries probablemente disminuye la necesidad de anestesia. Además, podría disminuir el dolor que experimenta el paciente, disminuir el riesgo del fracaso de la restauración y aumentar el tiempo del procedimiento, pero la certeza de la evidencia es baja. No es posible establecer con claridad si la remoción químico- mecánica disminuye el riesgo de exposición pulpar debido a que la certeza de la evidencia existente ha sido evaluada como muy baja.

INTRODUCTION: Carious lesions have traditionally been treated by non-selective (complete or total) removal of carious tissue. However, due to its risks and adverse effects, carious tissue removal techniques have been developed, based on the preservation of tooth tissue, including the stepwise removal. The objective of this summary is to clarify the uncertainty about the effectiveness and safety of the stepwise removal technique compared to complete removal. METHODS: To answer this question we used Epistemonikos, the largest database of systematic reviews in health, which is maintained by searching multiple sources of information, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from identified reviews, reanalyzed data from primary studies, performed a meta-analysis, and prepared summary tables of results using the GRADE method. RESULTS AND CONCLUSIONS: We identified three systematic reviews that included five primary studies, four of them corresponding to randomized trials. We concluded that stepwise removal may reduce the risk of pulp exposure, the risk of signs and symptoms of pulp disease and the risk of restoration failure, but the certainty of the evidence is low.
INTRODUCCION: Las lesiones cariosas han sido tradicionalmente tratadas mediante la remoción total (completa o no selectiva) del tejido cariado. Sin embargo, debido a sus riesgos y efectos adversos, se han desarrollado nuevas técnicas de remoción del tejido cariado, basadas en la conservación del tejido dentario, entre ellas la remoción en dos pasos o stepwise. El objetivo de este resumen es aclarar la incertidumbre sobre la efectividad y la seguridad de la técnica de remoción en dos pasos (stepwise) comparado con la remoción total. MÉTODOS: Para responder esta pregunta utilizamos Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante búsquedas en múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, reanalizamos los datos de los estudios primarios, realizamos un metaanálisis, preparamos tablas de resumen de los resultados utilizando el método GRADE. RESULTADOS Y CONCLUSIONES: Identificamos tres revisiones sistemáticas que en conjunto incluyeron cinco estudios primarios, de los cuales cuatro corresponden a ensayos aleatorizados. Concluimos que la remoción en dos pasos (stepwise) podría disminuir el riesgo de exposición pulpar, el riesgo de aparición de signos y síntomas pulpares y la falla en la restauración, pero la certeza de la evidencia es baja.

BACKGROUND: Evidence-based medicine (EBM) is defined as the integration of the best available evidence from scientific studies with clinical experience (and context) and with patients' values and preferences. The objective of the present study was to describe self-perceived EBM competencies in physicians and medical students enrolled in a massive virtual EBM course. METHODS: Analytical cross-sectional study. People interested in a free virtual EBM course fulfilled their data in a virtual form for their registration in September 2020. In this form, 22 competencies related to four dimensions of EBM were evaluated: asking a clinical question, search, analysis, and application; using a 5-option Likert scale. The resulting database was analyzed, selecting people who claimed to be physicians or medical students of 18 years or more. RESULTS: 1793 participants were included: 1130 medical students and 663 physicians; more than 80% lived in Peru. The frequency of participants who agreed or strongly agreed with feeling qualified in each competence ranged: from 39.2% to 57.8% for the competencies of the 'Asking a clinical question' dimension, from 39.2% to 56.1% for 'Search,' from 19.9% to 32.0% for 'Analysis,' and from 19.6% to 29.9% for 'Application.' Both in physicians and students, the lowest frequencies were for the competencies of interpretation of impact measures, graphs, and results of systematic reviews; as well as shared decision making and calculation of expected benefit. Physicians who graduated more recently scored better on competencies from search and analysis dimensions. CONCLUSION: Among physicians and medical students enrolled in the course, self-perception of competencies was lower in the dimensions of analysis and application. More recently graduated physicians seem to have a greater self-perception of their research and analysis skills, probably due to curricular updates.List of abbreviations: EBM: Evidence-based medicine; CIMBE, for its acronym in Spanish: International Course on Evidence-Based Medicine; SOCIMEP, for its acronym in Spanish: Peruvian Medical Student Scientific Society.

This study aims to determine the impact of the COVID-19 pandemic, specifically considering the mandatory social isolation measures implemented, on the perceived stress of a sample of dentists and dental students from Latin America and the Caribbean, as well as the associated sociodemographic and pandemic-related variables. A cross-sectional survey was conducted with a sample of 2036 dentists and dental students (1433 women). For the main outcome, the 14-item Perceived Stress Scale (PSS-14) was used. The survey also questioned sociodemographic aspects, questions on the COVID-19 pandemic, health variables, and habits. Descriptive, bivariate, and multivariate analyses (linear regression) were applied to observe the factors associated with perceived stress. The PSS-14 mean score was 24.76 (±11.76). Hierarchical regression models showed significant variables associated with the PSS-14 scores: income level during mandatory social isolation, having older adults under care during mandatory social isolation, self-perceived level of concern regarding COVID-19, self-perceived health, Coffee consumption during mandatory social isolation. In general terms, the pandemic has influenced the personal, social, labor, and everyday life of dental staff and affected the mental health of this population specifically when perceived stress is considered. Public policies, strategies, and mental health surveillance systems are required for this population.

BACKGROUND: Self-management (SM) interventions are supportive interventions systematically provided by healthcare professionals, peers, or laypersons to increase the skills and confidence of patients in their ability to manage chronic diseases. We had two objectives: (1) to summarise the preferences and experiences of patients and their caregivers (informal caregivers and healthcare professionals) with SM in four chronic diseases and (2) to identify and describe the relevant outcomes for SM interventions from these perspectives. METHODS: We conducted a mixed-methods scoping review of reviews. We searched three databases until December 2020 for quantitative, qualitative, or mixed-methods reviews exploring patients' and caregivers' preferences or experiences with SM in type 2 diabetes mellitus (T2DM), obesity, chronic obstructive pulmonary disease (COPD), and heart failure (HF). Quantitative data were narratively synthesised, and qualitative data followed a three-step descriptive thematic synthesis. Identified themes were categorised into outcomes or modifiable factors of SM interventions. RESULTS: We included 148 reviews covering T2DM (n = 53 [35.8%]), obesity (n = 20 [13.5%]), COPD (n = 32 [21.6%]), HF (n = 38 [25.7%]), and those with more than one disease (n = 5 [3.4%]). We identified 12 main themes. Eight described the process of SM (disease progression, SM behaviours, social support, interaction with healthcare professionals, access to healthcare, costs for patients, culturally defined roles and perceptions, and health knowledge), and four described their experiences with SM interventions (the perceived benefit of the intervention, individualised care, sense of community with peers, and usability of equipment). Most themes and subthemes were categorised as outcomes of SM interventions. CONCLUSION: The process of SM shaped the perspectives of patients and their caregivers on SM interventions. Their perspectives were influenced by the perceived benefit of the intervention, the sense of community with peers, the intervention's usability, and the level of individualised care. Our findings can inform the selection of patient-important outcomes, decision-making processes, including the formulation of recommendations, and the design and implementation of SM interventions.

Introduction: Dental caries is the most prevalent oral disease in Ecuador. In our country, there are no studies that have included the population of the Galapagos Islands. Fluoride application to incipient lesions of dental caries has shown to be effective in avoiding the use of invasive restorative procedures. Objectives: The objective of the EESO-Gal study is to determine the prevalence and incidence of dental caries and to evaluate the effect of supervised dental brushing, accompanied by periodic applications of fluoride varnish on incipient precarious lesions of schoolchildren in the Galapagos Islands. This article presents the protocol of the EESO-Gal study. Methods: A cohort is planned with Galapagos Islands schoolchildren to determine the prevalence and incidence of dental caries, with assessments every six months, during twenty-four months. Results: We expect to determine the prevalence and incidence of caries every six months, for twenty-four months, in schoolchildren between three and ten years of age, and obtain data to show the state of the caries conditions in Galapagos schoolchildren, with the inclusion of daily brushing at school, supervised by the teacher, and with the application of fluoride varnish every six months. Conclusions: The prevalence of dental caries and incidence after the program will demonstrate the importance of implementing oral health prevention and promotion actions to create hygiene and health habits from an early age.
Introducción: La caries dental es la enfermedad bucal más prevalente en Ecuador. En nuestro país no existen estudios que hayan considerado a la población de las Islas Galápagos. La aplicación de flúor sobre lesiones incipientes de caries dental ha demostrado efectividad para evitar ejecutar procedimientos invasivos restauradores. Objetivos: El objetivo del Estudio de Salud Oral Galápagos, EESO-Gal, es determinar la prevalencia e incidencia de caries dental y evaluar el efecto de la acción del cepillado dental supervisado, acompañado de aplicaciones periódicas de flúor en barniz sobre lesiones cariosas incipientes en escolares de las Islas Galápagos. Con este informe se busca reportar el protocolo del Estudio de Salud Oral Galápagos. Métodos: Se plantea realizar una cohorte con los escolares de las Islas Galápagos para determinar la prevalencia e incidencia de caries con evaluaciones cada seis meses durante veinticuatro meses. Resultados: Se espera determinar la prevalencia e incidencia de caries cada seis meses durante veinticuatro meses en escolares de tres a diez años y obtener datos que permitan evidenciar el estado de las condiciones de caries en los escolares de Galápagos con la inclusión del cepillado diario en la escuela, supervisado por el docente, y con la aplicación semestral del barniz de flúor. Conclusiones: La prevalencia de caries dental e incidencia después de las acciones tomadas demostrará la importancia de aplicar acciones de prevención y promoción de la salud oral, para crear hábitos de higiene y salud desde edades tempranas.

OBJECTIVE: To compare the effects of treatments for coronavirus disease 2019 (covid-19). DESIGN: Living systematic review and network meta-analysis. DATA SOURCES: WHO covid-19 database, a comprehensive multilingual source of global covid-19 literature, up to 3 December 2021 and six additional Chinese databases up to 20 February 2021. Studies identified as of 1 December 2021 were included in the analysis. STUDY SELECTION: Randomised clinical trials in which people with suspected, probable, or confirmed covid-19 were randomised to drug treatment or to standard care or placebo. Pairs of reviewers independently screened potentially eligible articles. METHODS: After duplicate data abstraction, a bayesian network meta-analysis was conducted. Risk of bias of the included studies was assessed using a modification of the Cochrane risk of bias 2.0 tool, and the certainty of the evidence using the grading of recommendations assessment, development, and evaluation (GRADE) approach. For each outcome, interventions were classified in groups from the most to the least beneficial or harmful following GRADE guidance. RESULTS: 463 trials enrolling 166 581 patients were included; 267 (57.7%) trials and 89 814 (53.9%) patients are new from the previous iteration; 265 (57.2%) trials evaluating treatments with at least 100 patients or 20 events met the threshold for inclusion in the analyses. Compared with standard care, three drugs reduced mortality in patients with mostly severe disease with at least moderate certainty: systemic corticosteroids (risk difference 23 fewer per 1000 patients, 95% credible interval 40 fewer to 7 fewer, moderate certainty), interleukin-6 receptor antagonists when given with corticosteroids (23 fewer per 1000, 36 fewer to 7 fewer, moderate certainty), and Janus kinase inhibitors (44 fewer per 1000, 64 fewer to 20 fewer, high certainty). Compared with standard care, two drugs probably reduce hospital admission in patients with non-severe disease: nirmatrelvir/ritonavir (36 fewer per 1000, 41 fewer to 26 fewer, moderate certainty) and molnupiravir (19 fewer per 1000, 29 fewer to 5 fewer, moderate certainty). Remdesivir may reduce hospital admission (29 fewer per 1000, 40 fewer to 6 fewer, low certainty). Only molnupiravir had at least moderate quality evidence of a reduction in time to symptom resolution (3.3 days fewer, 4.8 fewer to 1.6 fewer, moderate certainty); several others showed a possible benefit. Several drugs may increase the risk of adverse effects leading to drug discontinuation; hydroxychloroquine probably increases the risk of mechanical ventilation (moderate certainty). CONCLUSION: Corticosteroids, interleukin-6 receptor antagonists, and Janus kinase inhibitors probably reduce mortality and confer other important benefits in patients with severe covid-19. Molnupiravir and nirmatrelvir/ritonavir probably reduce admission to hospital in patients with non-severe covid-19. SYSTEMATIC REVIEW REGISTRATION: This review was not registered. The protocol is publicly available in the supplementary material. READERS' NOTE: This article is a living systematic review that will be updated to reflect emerging evidence.

En el Ecuador se presenta una alta prevalencia e incidencia de diferentes patologías bucales, este escenario es similar en muchos países de la región. Las enfermedades orales constituyen un problema de salud pública, debido a que requiere un alto costo en su manejo y control; es por ello que se ha generado énfasis en realizar actividades preventivas que permitan mejorar el panorama. Han sido varias las medidas adoptadas por entes gubernamentales en el Ecuador para reducir la incidencia principalmente de caries dental, desde la prevención masiva a través de la fluoración de diferentes elementos de consumo humano, la promoción y prevención de salud oral a través de la enseñanza de técnicas de cepillado dental, difusión del correcto uso de seda dental, detección temprana de placa bacteriana, charlas educativas motivadoras y colocación de sellantes en superficies oclusales de molares definitivos en escolares de poblaciones urbano-marginales y rurales. Sin embargo, dichas estrategias no han conseguido ser monitoreadas, evaluadas ni reportadas para conocer su efectividad en la mejora de la salud oral en nuestro país.
In Ecuador, there is a high prevalence and incidence of different oral pathologies, this scenario is similar in several countries in the region. Oral diseases constitute a Public Health issue, since they involve a high investment in their management and control. Thus, an emphasis in preventive activities has been placed to improve the impact of oral diseases. Several measures have been taken by the Ecuadorian government to reduce the incidence of dental caries, including massive prevention programmes. For instance, fluoridation of food and water, school teaching of right tooth brushing techniques and dental floss use, early detection of bacterial plaque, delivery of educational talks, and sealant placement on occlusal surfaces of permanent teeth in schoolchildren from deprived urban and rural populations. Nevertheless, these strategies have not been monitored, evaluated or reported in order to understand their success in improving the Oral Health status of our country.

BACKGROUND: Although cannabis and cannabinoids are widely used with therapeutic purposes, their claimed efficacy is highly controversial. For this reason, medical cannabis use is a broad field of research that is rapidly expanding. Our objectives are to identify, characterize, appraise, and organize the current available evidence surrounding therapeutic use of cannabis and cannabinoids, using evidence maps. METHODS: We searched PubMed, EMBASE, The Cochrane Library and CINAHL, to identify systematic reviews (SRs) published from their inception up to December 2017. Two authors assessed eligibility and extracted data independently. We assessed methodological quality of the included SRs using the AMSTAR tool. To illustrate the extent of use of medical cannabis, we organized the results according to identified PICO questions using bubble plots corresponding to different clinical scenarios. RESULTS: A total of 44 SRs published between 2001 and 2017 were included in this evidence mapping with data from 158 individual studies. We extracted 96 PICO questions in the following medical conditions: multiple sclerosis, movement disorders (e.g. Tourette Syndrome, Parkinson Disease), psychiatry conditions, Alzheimer disease, epilepsy, acute and chronic pain, cancer, neuropathic pain, symptoms related to cancer (e.g. emesis and anorexia related with chemotherapy), rheumatic disorders, HIV-related symptoms, glaucoma, and COPD. The evidence about these conditions is heterogeneous regarding the conclusions and the quality of the individual primary studies. The quality of the SRs was moderate to high according to AMSTAR scores. CONCLUSIONS: Evidence on medical uses of cannabis is broad. However, due to methodological limitations, conclusions were weak in most of the assessed comparisons. Evidence mapping methodology is useful to perform an overview of available research, since it is possible to systematically describe the extent and distribution of evidence, and to organize scattered data.

METHODS: We searched in Epistemonikos, the largest database of systematic reviews in health, which is maintained by screening multiple information sources, including MEDLINE, EMBASE, Cochrane, among others. We extracted data from the systematic reviews, reanalyzed data of primary studies, conducted a meta-analysis and generated a summary of findings table using the GRADE approach. RESULTS AND CONCLUSIONS: We identified seven systematic reviews including seven studies overall, of which all were randomized trials. We concluded that selective caries removal may decrease the need for root canal treatment and the risk of pulp exposure in teeth with deep caries, but the certainty of the evidence is low. It is not clear whether the selective removal of caries reduces the risk of appearance of signs and symptoms of pulp disease and the risk of restorations failure, as the certainty of the evidence is very low.

RESULTADOS Y CONCLUSIONES: Identificamos siete revisiones sistemáticas que en conjunto incluyeron siete estudios primarios, todos ellos correspondientes a ensayos aleatorizados. Concluimos que la remoción selectiva de caries podría disminuir la necesidad de tratamiento de endodoncia y el riesgo de exposición pulpar en dientes con caries profundas, pero la certeza de la evidencia es baja. No existe claridad de que la remoción selectiva de caries disminuya el riesgo de aparición de signos y síntomas de patología pulpar y el riesgo de fracaso de las restauraciones ya que la certeza de la evidencia es muy baja.

Introduction: Self-management (SM) interventions are complex interventions and one of the main components of high-quality chronic disease care for which the incorporation of the perspectives of patients and their informal caregivers is crucial. We aim to identify, appraise and synthesise the evidence exploring patients' and caregivers' perspectives on SM interventions. More precisely, we aim to 1) describe how they value the importance of outcomes of SM interventions, and 2) identify the factors that might impact on acceptability and feasibility of SM interventions based on their preferences and experiences. Methods and analysis: We will conduct four mixed-methods overviews as part of COMPAR-EU, a European Union (EU) funded project aimed to identify the most effective and cost-effective SM interventions for chronic obstructive pulmonary disease (COPD), heart failure (HF), obesity, and type 2 diabetes mellitus (T2DM). We will search in MEDLINE, CINAHL, and PsycINFO for systematic reviews of studies addressing patients' preferences on outcomes, or their experiences with SM alongside their disease trajectory or with SM interventions, published in English. Selection of studies and data extraction will be conducted in pairs. We will assess the overlap of studies and methodological quality. We will follow a three-step synthesis process: 1) narrative synthesis for quantitative evidence, 2) thematic synthesis for qualitative evidence, and 3) integration of findings in the interpretation phase. Additionally, we will consult on the relevance of findings with patients and their caregivers. Systematic review registration: PROSPERO CRD42019117867.
RESUMO
Introducción: El dermatofibrosarcoma protuberans(DFSP), es uno de los tumores cutáneos menos frecuentes, se clasifica dentro de los sarcomas fibrohistociticos y está caracterizado por un crecimiento lento y progresivo. Métodos: Se realizó una serie de casos retrospectiva de los pacientes con DFSP atendidos en el Centro de la Piel (CEPI) entre 2010 y 2019, se tomó en cuenta la información demográfica, características clínicas, tratamiento y su evolución. Resultados: Seis pacientes fueron diagnosticados y tratados por DFSP en el período evaluado, existió un predominio de mujeres (4 mujeres, 2 hombres) con una media de edad de 58.2 (DE =19,6), tres de ellos presentaron lesiones en forma de placa indurada y los restantes presentaron nódulo único, la localización de las lesiones fueron en hombro, cuello e hipogastrio. El tratamiento más utilizado fue la escisión amplia, ninguno de los pacientes presentó recidivas al primer y quinto año del seguimiento. Conclusión: Es necesario el reconocimiento de las características clínicas típicas de DFSP ya que podría pasar como una tumoración benigna de piel, por lo cual se debe apoyar con el estudio histopatológico frente a la sospecha de este tipo de lesión
Introduction: Dermatofibrosarcoma protuberans (DFSP) is one of the rare tumors found in the fibrohistocytic sarcomas and it is characterized by slow and progressive growth. Methods:A retrospective study of six cases treated at the Skin Center (CEPI) between 2010 and 2019 was carried out. We have take into account demographic information, characteristics, treatment and evolution of the lesions. Results:Six patients were diagnosed and treated by DFSP. There was a predominance of women (4 women, 2 men) with a mean age of 58.2 (SD = 19.6), three of them presented lesions in the form of indurated plaque and the rest presented a unique nodule. The locations of the lesions were the shoulder, neck and hypogastrium. The most commonly used treatment was wide excision, none of the patients presented recurrences at the first and fifth year of follow-up. Conclusion:Recognition of the typical clinical characteristics of DFSP is necessary since it could be mistaken as a benign tumor of the skin. The diagnosis must be always done by histopathological confirmation

The objective of this study was to provide evidence-based recommendations for endovascular aneurysm repair (EVAR) versus open surgical repair (OSR) for patients with a nonruptured abdominal aortic aneurysm (AAA). We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement and adhered to the Grading of Recommendations Assessment, Development and Evaluation (GRADE) framework. Both low- and high surgical risk patients treated with EVAR showed decreased 30-day mortality, but the low-risk group had no differences in 4-year mortality. Compared with friendly anatomy, patients with hostile anatomy had an increased risk of type I endoleak. Young patients may prefer OSR. Endovascular aneurysm repair was not cost-effective in Europe. Four conditional recommendations were formulated: (1) OSR for low-risk patients up to 80 years old, (2) EVAR for low-risk patients older than 80 years, (3) EVAR for high-risk patients as long as is anatomically feasible, and (4) OSR in patients in whom it is not anatomically feasible to perform EVAR. Based on GRADE criteria, either OSR or EVAR can be suggested to patients with nonruptured AAA taking into account their surgical risk, hostile anatomy, and age. Given the weakness of the recommendations, personal preferences are determinant.

BACKGROUND: The constant search for an improved esthetic dental material has led investigators to realize that its performance depends on the conditions where the material is used. It has been probed that the contact with mouth rinses triggers alterations, reason why the aim of this study was to identify their possible effects of it on the integrity of nanohybrid composite resin and resin modified glass ionomer. MATERIAL AND METHODS: A total of 144 samples were manufactured with two nanohybrid composite resins and two resin modified glass ionomer restorative materials. The specimens were immersed in one of the three mouthwashes used in the study, for a total of 1092 minutes, with intervals of contact with artificial saliva. This strategy simulates three years of constant use of mouthwashes. The samples weight and surface roughness measurement was recorded with a precision scale and profilometer, at different stages: At the beginning of the study, after 546 minutes (simulating one and a half year), and after 1092 minutes (simulating three years). RESULTS: The collected data on surface roughness and weight were submitted to the analysis of variance (ANOVA), with repeated measures of three factors. The results determined shifts in values in terms of weight and roughness in all the samples. The composite resin "Grandio" group was the one that showed bigger shifts, while the glass ionomer group "Vitremer" showed stability on its structure. The evaluated mouthwashes displayed similar behavior between each other. CONCLUSIONS: The use of mouthwashes triggered changes on the structure of both dental materials: composite resin and resin modified glass ionomer mostly associated with surface roughness. Key words:Glass ionomer, composite resin, mouthwash, roughness, degradation.
RESUMO
OBJECTIVE: The purpose of this single-blind (evaluators) and parallel design study was to evaluate whether exposure to a cola-based soft drink during bleaching treatment with 35% hydrogen peroxide (HP) affects color change and bleaching-induced tooth sensitivity. MATERIAL AND METHODS: Forty-four patients with central incisors darker than A2 were selected. Participants who did not drink cola-based soft drinks were assigned to the control group (CG), while participants who drank a cola-based soft drink at least twice a day were assigned to the experimental group (EG). For the CG, foods with staining dyes were restricted. For the EG, there was no restriction on food and patients were asked to rinse their mouths with a cola-based soft drink for 30 s, 4 times daily. For both groups, 2 sessions with three 15 min applications of 35% HP were performed. Shade evaluation was assessed via subjective (VITA classical and VITA bleacheguide shade guides) and objective methods (Easyshade spectrophotometer) at baseline, during bleaching (first, second, and third weeks), and post bleaching (1 week and 1 month). Patients recorded their sensitivity perceptions using a numerical rating scale and 0-10 visual analog scales. Variation in shade guide units and the 2 colors (DE) were evaluated with a Student's t-test (α = 0.05) and Mann-Whitney test (α = 0.05). Absolute risk of tooth sensitivity and intensity of tooth sensitivity were evaluated by a Chi-square test (α=0.05). RESULTS: Effective bleaching was observed for both groups after 30 days, without statistical difference (p > 0.08). There was no significant difference in absolute risk of bleaching-induced tooth sensitivity between the 2 groups (p = 0.74). Higher and significant scores in pain scales were detected for the EG in comparison to the CG (p < 0.05). CONCLUSION: Even that the cola-based soft drink exposure during in-office bleaching treatments did not affect the bleaching's effectiveness; patients reported a higher intensity in bleaching-induced tooth sensitivity.
RESUMO
BACKGROUND: The rate of successful pregnancies brought to term has barely increased since the first assisted reproductive technology (ART) technique became available. Vasodilators have been proposed to increase endometrial receptivity, thicken the endometrium, and favour uterine relaxation, all of which could improve uterine receptivity and enhance the chances for successful assisted pregnancy. OBJECTIVES: To evaluate the effectiveness and safety of vasodilators in women undergoing fertility treatment. SEARCH METHODS: We searched the following electronic databases, trial registers, and websites: the Cochrane Gynaecology and Fertility Group (CGF) Specialised Register of controlled trials, the Cochrane Central Register of of Controlled Trials, via the Cochrane Register of Studies Online (CRSO), MEDLINE, Embase, PsycINFO, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Web of Knowledge, the Open System for Information on Grey Literature in Europe (OpenSIGLE), the Latin American and Caribbean Health Science Information Database (LILACS), clinical trial registries, and the reference lists of relevant articles. We conducted the search in October 2017 and applied no language restrictions. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing vasodilators alone or in combination with other treatments versus placebo or no treatment or versus other agents in women undergoing fertility treatment. DATA COLLECTION AND ANALYSIS: Four review authors independently selected studies, assessed risk of bias, extracted data, and calculated risk ratios (RRs). We combined study data using a fixed-effect model and assessed evidence quality using Grades of Recommendation, Assessment, Development and Evaluation Working Group (GRADE) methods. Our primary outcomes were live birth or ongoing pregnancy and vasodilator side effects. Secondary outcomes included clinical pregnancy, endometrial thickness, multiple pregnancy, miscarriage, and ectopic pregnancy. MAIN RESULTS: We included 15 studies with a total of 1326 women. All included studies compared a vasodilator versus placebo or no treatment. We judged most of these studies as having unclear risk of bias. Overall, the quality of evidence was low to moderate for most outcomes. The main limitations were imprecision due to low numbers of events and participants and risk of bias due to unclear methods of randomisation.Vasodilators probably make little or no difference in rates of live birth compared with placebo or no treatment (RR 1.18, 95% confidence interval (CI) 0.83 to 1.69; three RCTs; N = 350; I² = 0%; moderate-quality evidence) but probably increase overall rates of side effects including headache and tachycardia (RR 2.35, 95% CI 1.51 to 3.66; four RCTs; N = 418; I² = 0%; moderate-quality evidence). Evidence suggests that if 236 per 1000 women achieve live birth with placebo or no treatment, then between 196 and 398 per 1000 will do so with the use of vasodilators.Compared with placebo or no treatment, vasodilators may slightly improve clinical pregnancy rates (RR 1.45, 95% CI 1.19 to 1.77; 11 RCTs; N = 1054; I² = 6%; low-quality evidence). Vasodilators probably make little or no difference in rates of multiple gestation (RR 1.15, 95% CI 0.55 to 2.42; three RCTs; N = 370; I² = 0%; low-quality evidence), miscarriage (RR 0.83, 95% CI 0.37 to 1.86; three RCTs; N = 350; I² = 0%; low-quality evidence), or ectopic pregnancy (RR 1.48, 95% CI 0.25 to 8.69; two RCTs; N = 250; I² = 5%; low-quality evidence). All studies found benefit for endometrial thickening, but reported effects varied (I² = 92%) and ranged from a mean difference of 0.80 higher (95% CI 0.18 to 1.42) to 3.57 higher (95% CI 3.01 to 4.13) with very low-quality evidence, so we are uncertain how to interpret these results. AUTHORS' CONCLUSIONS: Evidence was insufficient to show whether vasodilators increase the live birth rate in women undergoing fertility treatment. However, low-quality evidence suggests that vasodilators may slightly increase clinical pregnancy rates. Moderate-quality evidence shows that vasodilators increase overall side effects in comparison with placebo or no treatment. Adequately powered studies are needed so that each treatment can be evaluated more accurately.
