Anterior open bite self-correction after cessation of non-nutritive sucking habits: a systematic review.

BACKGROUND: Non-nutritive sucking habits likely may cause occlusal changes such as anterior open bite (AOB) if they persist over extended time. OBJECTIVES: To assess if there is self-correction of AOB after cessation of non-nutritive sucking habits in children older than 4 years old, through a systematic review. SEARCH METHODS: Data sources included PubMed, Scopus, Web of Science and Latin American and Caribbean Health Sciences (LILACS) databases, gray literature as Google Scholar, the database System for Information on Gray Literature in Europe (OpenGrey) and ProQuest Dissertations and Theses Database, also hand searches of the included studies references. SELECTION CRITERIA: Studies assessing occlusal changes in children aged 4-12 years with AOB traits and non-nutritive sucking habits after the discontinuation of the habit were included. DATA COLLECTION AND ANALYSIS: Two authors independently assessed eligibility and extracted data. The risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale and the Joanna Briggs Critical Appraisal Checklist for quasi-experimental studies. The confidence in cumulative evidence was assessed using the GRADE criteria. RESULTS: Over 3100 studies, only 5 met the inclusion criteria. There is often self-correction of AOB after discontinuing the non-nutritive sucking habit, even in cases older than 4 years old. The improvement ranged between 50 and 100%. The overall quality of evidence was very low. CONCLUSIONS: AOB self-correction after discontinuing a non-nutritive sucking habit is possible, even after 4 years old, although with very low certainty in the body of evidence. It is not clear after what age the removal from the habit is unlikely to facilitate AOB self-correction.

Parental acceptance toward behavior guidance techniques for pediatric dental visits: a meta-analysis.

This study aimed to answer the following question: What is the proportion of acceptance reported by parents toward pediatric behavior guidance techniques (BGTs)? Observational studies that evaluated parental acceptance of BGTs during pediatric dental visits among parents of non-special health care need (non-SHCN) and SHCN children were included. A search of the Cochrane Library, Latin American and Caribbean Health Sciences (LILACS), MedLine/PubMed, PsycINFO, Scopus, and Web of Science databases, in addition to gray literature, was performed until October 2021. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment. The certainty of evidence was assessed using the Recommendation, Assessment, Development, and Evaluation (Grade). Fifty-three studies with 4868 participants were included, and 42 were retained for the random-effects proportion meta-analysis. The methodological quality varied from low to high. The agreement with the BGTs varied from 85.6% (95%CI: 77.5-92.1; p < 0.001; I 2 = 93.6%; 16 studies; n = 1399) for tell-show-do to 25.7% (95%CI: 17.8-34.4; p < 0.001; I 2 = 90.4%; 12 studies; n = 1129) for passive protective stabilization among non-SHCN children's parents; meanwhile, among the parents of SHCN children, it varied from 89.1% (95%CI: 56.1-99.7; p < 0.001; I 2 = 95.7%; 3 studies; n = 454) for tell-show-do to 29.1% (95%CI: 11.8-50.0; p = 0.001; I 2 = 84.8%; 3 studies; n = 263) for general anesthesia. The effect estimates varied greatly, as substantial heterogeneity across studies was observed, thus limiting the confidence in the results. Parents were more likely to agree with basic BGTs over advanced BGTs, with very low certainty of evidence. Dentists should discuss BGT options with parents.

Association between genetic polymorphisms in the melatonin receptor type 1 A gene and sleep bruxism.

OBJECTIVE: This study evaluated whether single nucleotide polymorphisms in the melatonin receptor type 1 A gene are associated with sleep bruxism in a Brazilian population. DESIGN: Individuals with suspected sleep-related problems were evaluated using polysomnography, following the recommendations proposed by the American Academy of Sleep Medicine and the Research Diagnostic Criteria for Temporomandibular Disorders. Deoxyribonucleic acid (DNA) samples were collected, and three single nucleotide polymorphisms in the melatonin receptor type 1 A gene (rs13140012, rs6553010, and rs6847693) were selected and genotyped using real-time polymerase chain reaction (RT-PCR). Chi-square and odds ratio tests were used to analyze genotypes and alleles individually, while using the plink software for haplotypes. A confidence interval of 95% was considered, and statistical significance was set at p < 0.05. RESULTS: This study included 48 individuals aged between 21 and 80 years, with 27 males and 21 females. From this sample, 17 individuals were diagnosed with sleep bruxism and 31 without bruxism. No associations were found between sleep bruxism and single nucleotide polymorphisms in either the genotypic, allelic, dominant, or recessive models (p > 0.05). Haplotype genetic analysis also did not reveal any association between single nucleotide polymorphisms and sleep bruxism (p > 0.05). CONCLUSION: The genetic polymorphisms rs6553010, rs13140012, and rs6847693 were not associated with sleep bruxism in the studied population.

BURNOUT SYNDROME AMONG DENTISTS: A SYSTEMATIC REVIEW AND META-ANALYSIS.

OBJECTIVE: Burnout syndrome has negative consequences on the dentist's health and performance during work. This systematic review aimed to assess the prevalence of Burnout syndrome in dentists. METHODS: Searches were carried out in Medline, Scopus, Web of Science, PsycINFO, EMBASE, LILACS databases, and searches in the gray literature on January 27, 2021. There were no restrictions on language and search period. For the diagnosis of Burnout, only studies that used the Maslach burnout inventory questionnaire and its subscales emotional exhaustion (EE), depersonalization (DP), and reduced personal accomplishment (PA) were included. Proportion meta-analyses were performed using the Stata 13.0 software. RESULTS: A total of 37 articles were included in the narrative and 31 in quantitative syntheses. The overall prevalence of Burnout syndrome in dentists was 13% (95% confidence interval [CI]: 0.006-0.21; I²: 97.07%) and the total prevalence in the subscales EE, DP, and PA, were, respectively: 28% (95% CI: 0.24-0.32; I²: 20.70%), 18% (95% CI: 0.08-0.28; I²: 85.61%) and 10% (95% CI: 0.08-0.13; I²: 0%). About the levels of Burnout syndrome in the subscales, 25% (95% CI: 0.19-0.31; I² 92.58%) presented high EE, 18% (95% CI: 0.10-0.26; I² 96.62%) high DP and 32% (95% 0.20-0.45; I² 97.86%) low PA. About continuous data, the mean of EE, DP and PA was respectively 17.90 (95% CI: 9.36-26.43; I² 94.8), 6.93 (95% CI: 3.41-10.45; I² 80.2) and, 34.69 (95% CI: 23.82-45.55; I² 98.8). No study presented all the positive criteria of the Joanna Briggs Institute Critical Appraisal checklist. CONCLUSION: In conclusion, there was a considerable prevalence of burnout syndrome in dentists, mainly in the subscale of emotional exhaustion.

Lysosomal acid lipase deficiency in pediatric patients: a scoping review

Abstract Objective: Lysosomal acid lipase deficiency (LAL-D) is an underdiagnosed autosomal recessive disease with onset between the first years of life and adulthood. Early diagnosis is crucial for effective therapy and long-term survival. The objective of this article is to recognize warning signs among the clinical and laboratory characteristics of LAL-D in pediatric patients through a scope review. Sources: Electronic searches in the Embase, PubMed, Livivo, LILACS, Web of Science, Scopus, Google Scholar, Open Gray, and ProQuest Dissertations and Theses databases. The dataset included observational studies with clinical and laboratory characteristics of infants, children and adolescents diagnosed with lysosomal acid lipase deficiency by enzyme activity testing or analysis of mutations in the lysosomal acid lipase gene (LIPA). The reference selection process was performed in two stages. The references were selected by two authors, and the data were extracted in June 2020. Summary of the findings: The initial search returned 1593 studies, and the final selection included 108 studies from 30 countries encompassing 206 patients, including individuals with Wolman disease and cholesteryl ester storage disease (CESD). The most prevalent manifestations in both spectra of the disease were hepatomegaly, splenomegaly, anemia, dyslipidemia, and elevated transaminases. Conclusions: Vomiting, diarrhea, jaundice, and splenomegaly may be correlated, and may serve as a starting point for investigating LAL-D. Familial lymphohistiocytosis should be part of the differential diagnosis with LAL-D, and all patients undergoing upper gastrointestinal endoscopy should be submitted to intestinal biopsy.

Estimating underdiagnosis of COVID-19 with nowcasting and machine learning.

OBJECTIVE: To analyze the underdiagnosis of COVID-19 through nowcasting with machine learning in a Southern Brazilian capital city. METHODS: Observational ecological design and data from 3916 notified cases of COVID-19 from April 14th to June 2nd, 2020 in Florianópolis, Brazil. A machine-learning algorithm was used to classify cases that had no diagnosis, producing the nowcast. To analyze the underdiagnosis, the difference between data without nowcasting and the median of the nowcasted projections for the entire period and for the six days from the date of onset of symptoms were compared. RESULTS: The number of new cases throughout the entire period without nowcasting was 389. With nowcasting, it was 694 (95%CI 496-897). During the six-day period, the number without nowcasting was 19 and 104 (95%CI 60-142) with nowcasting. The underdiagnosis was 37.29% in the entire period and 81.73% in the six-day period. The underdiagnosis was more critical in the six days from the date of onset of symptoms to diagnosis before the data collection than in the entire period. CONCLUSION: The use of nowcasting with machine learning techniques can help to estimate the number of new disease cases.

Association between obstructive sleep apnea and health-related quality of life in untreated adults: a systematic review.

PURPOSE: The objective of this systematic review was to answer the question: "Is there association between obstructive sleep apnea (OSA) and health-related quality of life (HRQoL) in untreated adults?" METHODS: We included observational studies that evaluated the health-related quality of life of patients with OSA vs control groups, through generic and disease-specific questionnaires. The searches were conducted in six databases: Embase, Lilacs, PsycINFO, PubMed, Scopus, and Web of Science. Additional search in the grey literature and hand search were performed, and also experts were consulted. Risk of bias was performed by using Joanna Briggs Institute Critical Appraisal Checklist for cross-sectional, cohort, and case-control studies. We analyzed the data using a narrative synthesis. The Grading of Recommendations Assessment, Development, and Evaluation evidence profile was used to verify the overall certainty of the assessed evidence. RESULTS: Nineteen studies were included for qualitative analysis. Generic questionnaires showed worse HRQoL in the OSA group compared to the control group in at least one domain of the HRQoL questionnaires. The affected domains that showed statistical and clinically relevant differences were physical functioning, physical role, pain, general health, vitality, emotional role, and mental health. The certainty of evidence assessment was very low. CONCLUSION: The available literature suggests that OSA in untreated adults is associated with worse HRQoL. However, this association seems to disappear when we consider only studies adjusted for related covariates. REGISTRATION: CRD42018114746.

Biomarkers in biological fluids in adults with periodontitis and/or obesity: A meta-analysis.

Obesity and periodontal diseases have been investigated to be interconnected, but the molecular mechanism underlying this association is still not clear. The aim of this systematic review is to assess the association of serum, salivary and gingival crevicular fluid (GCF) inflammatory markers (IMs), obesity, and periodontitis. Studies that evaluated IM of adults according to obesity status (O) and periodontitis status (P) (O+P+; O-P+; O+P-) were screened on several electronic databases and grey literature up until February 2019. Risk of bias assessment and level of evidence were evaluated through Fowkes and Fulton scale and Grading of Recommendations Assessment, Development and Evaluation (GRADE). Meta-analyses were grouped according to the biological matrix studied (serum/GCF) and groups (O+P+ vs. O-P+/O+P+ vs. O+P-). Out of the 832 studies screened, 21 were considered in qualitative synthesis and 15 in quantitative synthesis (meta-analysis). Although included studies showed mostly "no" or "minor" problems during the quality assessment, GRADE assessment indicated very low to moderate level of evidence based on the question answered. O+P+ adults exhibited significantly higher serum levels of C-reactive protein (CRP), interleukin 6 (IL-6), leptin, and tumor necrosis factor-α (TNF-alpha) and higher resistin GCF levels than O-P+. O+P+ adults showed significantly higher serum levels of IL-6 and leptin and lower adiponectin serum levels than O+P-. Only qualitative information could be obtained of the IM vaspin, omentin-1, chemerin, IL-10, progranulin, MCP-4, IL-1ß, and interferon-γ (IFN-γ). Obesity and periodontitis, together or separately, are associated with altered serum and GCF levels of CRP, IL-6, leptin, TNF-alpha, adiponectin, and resistin. It was not possible to evaluate the association between obesity and periodontitis at salivary levels. The role of recently investigated biomarkers as vaspin, omentin-1, chemerin, IL-10, progranulin, MCP-4, IL-1ß, and IFN-γ, which can be key points underlying the association between obesity and periodontitis, remains to be further investigated.

Effects of dual blockade in heart failure and renal dysfunction: Systematic review and meta-analysis.

OBJECTIVE: The effect of dual renin-angiotensin system (RAS) inhibition in heart failure (HF) is still controversial. Systematic reviews have shown that dual RAS blockade may reduce mortality and hospitalizations, yet it has been associated with the increased risk of renal dysfunction (RD). Surprisingly, although RD in patients with HF is frequent, the effect of combining RAS inhibitors in HF patients with RD has never been studied in a meta-analysis. METHODS: A systematic review and meta-analysis of randomized clinical trials involving HF patients with RD who received dual blockade analyzing death, cardiovascular (CV) death or HF hospitalization, and adverse events. RESULTS: Out of 2258 screened articles, 12 studies were included (34,131 patients). Compared with monotherapy, dual RAS inhibition reduced hazard ratio of death to 0.94 (p=0.07) and significantly reduced CV death or HF hospitalization to 0.89 (p=0.0006) in all individuals, and to 0.86 (p=0.005) in patients with RD and to 0.91 (p=0.04) without RD. Nevertheless, dual RAS blockade significantly increased the risk of renal impairment (40%), hyperkalemia (44%), and hypotension (42%), although discontinuation of treatment occurs only in 3.68% versus 2.19% (p=0.00001). CONCLUSIONS: Dual RAS inhibition therapy reduces the risk of CV death or HF hospitalization. However, cautions monitoring for specific adverse events may be warranted.

Diagnostic validity of biomarkers in Parkinson's Disease: systematic review and meta-analysis.

OBJECTIVE: To identify biomarkers for Parkinson's disease, cerebrospinal fluid, blood, saliva, and urine. METHOD: The studies were collected from the Cochrane, LILACS, PubMed, SCOPUS, WEB OF SCIENCE, OpenGrey, ProQuest and Google Scholar databases starting from May 3, 2016 and updated on March 20, 2017. Twenty-two studies were evaluated, by the Quality Assessment Tool for Diagnostic Accuracy Studies and Review Manager 5.3. RESULTS: Evidence shows that serum antibodies can be used as highly specific and accurate biomarkers for the diagnosis of Parkinson's disease at the outset. Biomarkers in the cerebrospinal fluid are related to increased motor severity, postural instability, gait abnormality, and cognitive impairment. CONCLUSION: Serum and cerebrospinal antibodies can be used as diagnostic biomarkers at the onset of the disease.

Diagnostic validity of methods for assessment of swallowing sounds: a systematic review / Validade diagnóstica dos métodos de avaliação dos sons de deglutição: uma revisão sistemática

Abstract Introduction: Oropharyngeal dysphagia is a highly prevalent comorbidity in neurological patients and presents a serious health threat, which may lead to outcomes of aspiration pneumonia, ranging from hospitalization to death. This assessment proposes a non-invasive, acoustic-based method to differentiate between individuals with and without signals of penetration and aspiration. Objective: This systematic review evaluated the diagnostic validity of different methods for assessment of swallowing sounds, when compared to videofluroscopy swallowing study to detect oropharyngeal dysphagia. Methods: Articles in which the primary objective was to evaluate the accuracy of swallowing sounds were searched in five electronic databases with no language or time limitations. Accuracy measurements described in the studies were transformed to construct receiver operating characteristic curves and forest plots with the aid of Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Denmark). The methodology of the selected studies was evaluated using the Quality Assessment Tool for Diagnostic Accuracy Studies-2. Results: The final electronic search revealed 554 records, however only 3 studies met the inclusion criteria. The accuracy values (area under the curve) were 0.94 for microphone, 0.80 for doppler, and 0.60 for stethoscope. Conclusion: Based on limited evidence and low methodological quality because few studies were included, with a small sample size, from all index testes found for this systematic review, doppler showed excellent diagnostic accuracy for the discrimination of swallowing sounds, whereas microphone-reported good accuracy discrimination of swallowing sounds of dysphagic patients and stethoscope showed best screening test.

Resumo Introdução: A disfagia orofaríngea é uma comorbidade altamente prevalente em pacientes neurológicos e representa uma séria ameaça à saúde, pode levar a desfechos como pneumonia por aspiração, hospitalização e até morte. A avaliação propõe um método não invasivo, acústico, para diferenciar entre indivíduos com e sem sinais de penetração e aspiração. Objetivo: Esta revisão sistemática analisou a validade diagnóstica de diferentes métodos para avaliação dos sons de deglutição, quando comparados com a videofluoroscopia da deglutição para detectar disfagia orofaríngea. Método: Artigos nos quais o objetivo principal era avaliar a acurácia dos sons de deglutição foram pesquisados em cinco bancos de dados eletrônicos sem limitações de idioma ou tempo de publicação. As medidas de acurácia descritas nos estudos foram transformadas para construir curvas ROC (Receptor Operating Characteristic) e gráfico em floresta (forest plot) com o auxílio do software Review Manager v. 5.2 (The Nordic Cochrane Centre, Copenhagen, Dinamarca). A metodologia dos estudos selecionados foi avaliada com a ferramenta Avaliação da Qualidade de Estudos de Acurácia de Testes Diagnósticos-2. Resultados: A busca eletrônica final resultou na identificação de 554 artigos; no entanto, apenas três estudos preencheram os critérios de inclusão. Os valores de acurácia (área abaixo da curva) foram 0,94 para microfone, 0,80 para doppler e 0,60 para estetoscópio. Conclusão: Baseado nas evidências limitadas e da baixa qualidade metodológica, pois foram poucos os estudos incluídos, e com pequeno tamanho amostral, de todos os testes diagnósticos (index testes) encontrados para essa revisão sistemática o doppler mostrou excelente acurácia diagnóstica na discriminação dos sons de deglutição, o microfone demonstrou uma boa acurácia na discriminação dos sons de pacientes disfágicos e o estetoscópio revelou o melhor teste de triagem.

Use of trolamine to prevent and treat acute radiation dermatitis: a systematic review and meta-analysis.

OBJECTIVE: to evaluate the effects of trolamine in the prevention or treatment of radiation dermatitis. METHOD: systematic review and meta-analysis. Detailed individual search strategies for Cinahl, Cochrane Library Central, LILACS, PubMed, and Web of Science were developed in January 2016. A manual search was also performed to find additional references. A grey literature search was executed by using Google Scholar. Two researchers independently read the titles and abstracts from every cross-reference. The risk of bias of the included studies was analyzed by the Cochrane Collaboration Risk of Bias Tool. The quality of evidence and grading of strength of recommendations was assessed using Grades of Recommendation, Assessment, Development and Evaluation (GRADE). RESULTS: seven controlled clinical trials were identified. The controls used were calendula, placebo, institutional preference / usual care, Aquaphor®, RadiaCare™, and Lipiderm™. The studies were pooled using frequency of events and risk ratio with 95% confidence intervals, in subgroups according to radiation dermatitis graduation. CONCLUSION: based on the studies included in this review, trolamine cannot be considered as a standardized product to prevent or treat radiation dermatitis in patients with breast and head and neck cancer.

Dietary Patterns of Children and Adolescents from High, Medium and Low Human Development Countries and Associated Socioeconomic Factors: A Systematic Review.

The purpose of this systematic review is to assess the associations among education, income and dietary pattern (DP) in children and adolescents from high, medium and low human development countries (HHDC, MHDC and LHDC, respectively). Observational studies that evaluated the association between family income or education with the DP are obtained through electronic database searches. Forty articles are selected for review. In HHDC, education is inversely associated with "unhealthy" DP and positively associated with "healthy" DP. In cross-sectional studies from HHDC, higher income is negatively associated with "unhealthy" DP. In MHDC, there is no association between the socioeconomic variables (SE) and the DPs, although, in some studies, the unhealthy diet is positively associated with SE. Only one study conducted in LHDC showed an inverse association between income/education with "unhealthy" DP and there is no association between the SE and "healthy" DP. In conclusion, children and adolescents living in HHDC with high parental education tend to have a healthier diet. In MHDC, although an unhealthy diet is found among the high-income and educated population, the associations are not clear. Additional research is needed to clarify the associations between income and education with "unhealthy" and "healthy" DPs in MHDC and LHDC.

Diagnostic validity of CT to assess degenerative temporomandibular joint disease: a systematic review.

OBJECTIVES: The aim of this systematic review was to answer the focus question: "In subjects with degenerative joint disease (DJD) of the temporomandibular joint (TMJ), what is the diagnostic validity of CT or cone-beam CT (CBCT) compared with clinical protocols"? METHODS: DJD should be assessed through clinical diagnosis according to RDC/TMD or DC/TMD. Search strategies were specifically developed to the following electronic databases: Cochrane, Latin American And Caribbean Health Sciences (LILACS), PubMed (including Medline), Scopus and Web of Science. Furthermore, partial grey literature search through Google Scholar, OpenGrey and ProQuest was performed. The risk of bias was evaluated using the second version of Quality Assessment Tool for Diagnostic Accuracy Studies (QUADAS-2). RESULTS: The databases search revealed 454 records. After applying the eligibility criteria, four studies were included in this review. All studies were methodologically acceptable, although none of the them fulfilled all criteria of risk of bias according to QUADAS-2. Despite there were some high values for sensitivity and specificity, they were not homogeneous between studies. Regarding specificity outcomes, there were three studies with poor values and only one considered as excellent. CONCLUSIONS: CBCT could be a good image to evaluate DJD progression over time, but should not be used as a screening tool in healthy individuals.

Use of trolamine to prevent and treat acute radiation dermatitis: a systematic review and meta-analysis / Uso de trolamina para prevenção e tratamento da radiodermatite aguda: revisão sistemática e meta-análise / Uso de trolamina para prevención y tratamiento de radiodermatitis aguda: revisión sistemática y meta-análisis

ABSTRACT Objective: to evaluate the effects of trolamine in the prevention or treatment of radiation dermatitis. Method: systematic review and meta-analysis. Detailed individual search strategies for Cinahl, Cochrane Library Central, LILACS, PubMed, and Web of Science were developed in January 2016. A manual search was also performed to find additional references. A grey literature search was executed by using Google Scholar. Two researchers independently read the titles and abstracts from every cross-reference. The risk of bias of the included studies was analyzed by the Cochrane Collaboration Risk of Bias Tool. The quality of evidence and grading of strength of recommendations was assessed using Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Results: seven controlled clinical trials were identified. The controls used were calendula, placebo, institutional preference / usual care, Aquaphor®, RadiaCare™, and Lipiderm™. The studies were pooled using frequency of events and risk ratio with 95% confidence intervals, in subgroups according to radiation dermatitis graduation. Conclusion: based on the studies included in this review, trolamine cannot be considered as a standardized product to prevent or treat radiation dermatitis in patients with breast and head and neck cancer.

RESUMO Objetivo: avaliar os efeitos da trolamina na prevenção ou no tratamento da radiodermatite. Método: revisão sistemática e meta-análise. Em janeiro de 2016, foram desenvolvidas estratégias detalhadas de busca individual para Cinahl, Cochrane Library Central, LILACS, PubMed e Web of Science. Também foram realizadas buscas manuais para encontrar referências adicionais. Se utilizou Google Scholar para buscar a literatura cinzenta. Dois investigadores leram os títulos e resumos de cada referência cruzada de forma independente. O risco de viés dos estudos incluídos foi analisado com a ferramenta Cochrane Collaboration Risk of Bias Tool. A qualidade das evidências e a classificação da força das recomendações foram avaliadas mediante os Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Resultados: foram identificados sete ensaios clínicos controlados. Os controles utilizados foram calêndula, placebo, preferência institucional / atenção padrão, Aquaphor®, RadiaCare™ e Lipiderm™. Os estudos foram agrupados utilizando a frequência de eventos e o índice de risco com intervalos de confiança de 95% em subgrupos, de acordo com a graduação da radiodermatite. Conclusão: com base nos estudos incluídos nesta revisão, a trolamina não pode ser considerada um produto padronizado para a prevenção ou o tratamento da radiodermatite em pacientes com câncer de mama e cabeça e pescoço.

RESUMEN Objetivo: evaluar los efectos de la trolamina en la prevención o el tratamiento de la radiodermatitis. Método: revisión sistemática y meta-análisis. En enero de 2016 se desarrollaron estrategias detalladas de búsqueda individual para Cinahl, Cochrane Library Central, LILACS, PubMed y Web of Science. También se realizaron búsquedas manuales para encontrar referencias adicionales. Se utilizó Google Scholar para buscar literatura gris. Dos investigadores leyeron los títulos y los resúmenes de cada referencia cruzada independientemente. El riesgo de sesgo de los estudios incluidos fue analizado por la herramienta Cochrane Collaboration Risk of Bias Tool. La calidad de la evidencia y la clasificación de la fuerza de las recomendaciones se evaluó mediante los Grades of Recommendation, Assessment, Development and Evaluation (GRADE). Resultados: se identificaron siete ensayos clínicos controlados. Los controles utilizados fueron caléndula, placebo, preferencia institucional / atención habitual, Aquaphor®, RadiaCare™ y Lipiderm™. Los estudios se agruparon utilizando la frecuencia de eventos y la razón de riesgo con intervalos de confianza del 95%, en subgrupos según la graduación de radiodermatitis. Conclusión: con base en los estudios incluidos en esta revisión, la trolamina no puede considerarse un producto estandarizado para prevenir o tratar la radiodermatitis en pacientes con cáncer de mama y cabeza y cuello.
