Efficacy of Enamel Derivatives to Improve Keratinized Tissue as Adjunct to Coverage of Gingival Recessions: A Systematic Review and Meta-Analysis

Background: The systematic review was designed to answer the following focused question: Are enamel matrix derivatives able to improve the quantity of keratinized tissue (KT) around natural dentition in patients with recessions defects after their treatment with periodontal plastic procedures? Methods: Only Randomized Clinical Trials (RCT) in English language evaluating root coverage procedures in combination with enamel matrix derivatives (commercially known as Emdogain®—EMD), with at least 10 subjects and a minimum duration of six months, were included. The search was applied to PUBMED and SCOPUS and it consists of a combination of MeSH terms and free text words (from January 2000 to June 2019). Risk of bias in individual studies and across studies was also evaluated. Results: After the full text analysis and the exclusion of further 18 articles, 12 articles were finally included. In total 639 recessions were treated (334 tests and 305 control). The recessions defects were classified according to the classification of Miller (Class I, II, III, IV). Only one trial included Miller Class III recessions (7 in total). Enamel matrix derivatives were applied in conjunction with Coronally Advanced Flap (CAF), Coronally Advanced Flap + Sub Epithelial Connective Tissue Graft (CAF + CTG), Semilunar Flap (SF). For the group CAF vs CAF + EMD the mean difference between the keratinized tissue gain in the two procedures was 0.40 mm (95% Confindence Interval Lower/Upper: 0.014–0.81) (p < 0.058); for the comparison CAF + CTG + EMD vs. CAF + CTG the mean difference between the two groups resulted in −0.06 mm (95% Confindence Interval Lower Upper −0.45 to 0.33) (p = 0.7603). Discussion: Randomized clinical trials included medium-low quality evidence. The application of Enamel Matrix Derivatives to surgical procedures aimed to cover gingival recessions does not add robust clinical benefit to conventional plastic procedure alone

Automatic prediction of cardiovascular and cerebrovascular events using heart rate variability analysis

Background There is consensus that Heart Rate Variability is associated with the risk of vascular events. However, Heart Rate Variability predictive value for vascular events is not completely clear. The aim of this study is to develop novel predictive models based on data-mining algorithms to provide an automatic risk stratification tool for hypertensive patients. Methods A database of 139 Holter recordings with clinical data of hypertensive patients followed up for at least 12 months were collected ad hoc. Subjects who experienced a vascular event (i.e., myocardial infarction, stroke, syncopal event) were considered as high-risk subjects. Several data-mining algorithms (such as support vector machine, tree-based classifier, artificial neural network) were used to develop automatic classifiers and their accuracy was tested by assessing the receiver-operator characteristics curve. Moreover, we tested the echographic parameters, which have been showed as powerful predictors of future vascular events. Results The best predictive model was based on random forest and enabled to identify high-risk hypertensive patients with sensitivity and specificity rates of 71.4% and 87.8%, respectively. The Heart Rate Variability based classifier showed higher predictive values than the conventional echographic parameters, which are considered as significant cardiovascular risk factors. Conclusions Combination of Heart Rate Variability measures, analyzed with data-mining algorithm, could be a reliable tool for identifying hypertensive patients at high risk to develop future vascular events

Ageing-Oriented Prosthetic Treatment Plan: A Case Report

Today, older adults are routinely classified into different categories based on their degrees of independence. However, due to the extreme heterogeneity of this group, and the fact that ageing is a progressive process, older adults may require customized prosthetic treatment. Older people, during ageing, may quickly pass into a frail condition, with loss of independence and of the manual skills necessary for proper hygiene maintenance. With this in mind, complete arch rehabilitations can make an important contribution to a patient’s quality of life. New treatment strategies are needed which take into account the priorities of ageing. The aim of this case report is to show an adaptable prosthetic treatment protocol that is useful for older adults. This protocol provides individual satisfaction and also aids forecasting of the patient’s future functional and maintenance needs

Efficacy of Behaviour Change Techniques to improve oral hygiene control of individuals undergoing orthodontic therapy. A systematic review

Aim: This study aims to review the available evidence on the efficacy of behaviour change techniques to improve compliance in young orthodontic patients and to compare these with conventional oral hygiene instructions. Methods: The review was conducted according to the PRISMA statement. PICO method was used to define eligibility criteria. Two independent reviewers performed the research, examined electronic databases (MEDLINE, Scopus and CENTRAL) and manually checked relevant journals. Only RCTs with more than 10 participants and 3 months follow-up were included. Data extraction and their qualitative analysis were performed for included studies. Results: Search strategy identified 320 articles. After screening for titles, abstracts and full texts, 10 articles were then selected for qualitative analysis. High methodological heterogeneity was present among studies and therefore no meta-analysis was performed. Low risk of bias was detected for one study only. The most common intervention was “mobile phone communication,” which was investigated in five studies. Motivational interviewing, repeated reinforcements and visual-aided approach were also examined. Conclusion: The interest in remote control of patients compliance appears to be fruitful, nonetheless there is no consensus as to a unique treatment protocol. Every other treatment looks beneficial but higher methodological homogeneity should be sought for in future investigations. © 2020 John Wiley & Sons A/S. Published by John Wiley & Sons Lt

Patients’ illness perception before and after non‐surgical periodontal therapy. A pre‐post quasi‐experimental study

Background: Patient's illness perception, assessed through the Brief-Illness Perception Questionnaire (Brief-IPQ), plays a decisive role in the treatment effectiveness of a wide range of chronic diseases; nonetheless, evidence is still lacking regarding periodontitis. The aim of the present pre-post quasi-experimental study was to evaluate the change in the Brief-IPQ before and after non-surgical periodontal treatment (NST) and to evaluate its ability to foresee the efficacy of NST. Methods: A total of 126 periodontitis participants starting NST were asked to participate in the study. The nine-item Brief-IPQ together with a full periodontal chart were recorded at baseline and at the 3-month follow up (reevaluation) after NST. Pre-post comparisons of psychometric and periodontal variables were carried out through the Wilcoxon signed-rank test (α = 0.05). A predictive model was built to test the ability of the Brief-IPQ items to foresee the efficacy of NST. Results: NST led to a significant reduction in all periodontal parameters (P < 0.001); the proportion of pockets closed was 64.18%. Although the overall sum score of the Brief-IPQ remained fairly stable (P = 0.0673), significant changes occurred for items seven ("understanding") (P < 0.001) and 8 ("emotional response") (P < 0.05). The best model (R2 = 0.068, F = 2.15, P = 0.033) obtained from the multivariate linear regression analysis demonstrated that item five ("identity") (β = 2.340, P = 0.017) and item eight ("emotional response") (β = -2.569, P = 0.008) significantly predict the efficacy of NST (i.e., the proportion of pockets closed at reevaluation). Conclusions: NST significantly ameliorates patient's understanding and emotional burden related to periodontitis. Baseline values of perceived symptoms and emotional response are predictive for the short-term efficacy of NST. © 2021 American Academy of Periodontolog

Is Tako-tsubo syndrome in the postpartum period a clinical entity different from peripartum cardiomyopathy?

AIMS: To conduct a systematic review of case reports about Tako-tsubo syndrome (TTS) after delivery in order to assess whether TTS in the postpartum period is a peculiar entity or only a variant form of peripartum cardiomyopathy. METHODS: We performed a systematic literature search on the occurrence of TTS after Cesarean section or spontaneous delivery using the scientific literature databases Medline, EMBASE and the Cochrane library. We selected 14 case reports in English. Primary/elective cesarean section or spontaneous delivery; absence of preexisting cardiovascular disease or fetal malformations; identification of diagnostic criteria for TTS; onset of TTS symptoms after delivery were the inclusion criteria. RESULTS: Fifteen cases were selected. Cesarean section 24h before the onset of TTS was reported in 13. All patients presented dyspnea or chest pain. The majority had mild troponin elevation, non-ST-segment elevation. Apical ballooning was observed in 60% of cases, midventricular ballooning in 33%, basal ballooning in 7%. Although 13 patients experienced acute cardiac complications (pulmonary edema, cardiogenic shock, cardiac arrest), in all left ventricular systolic function normalized within 13.43±10.96 days. CONCLUSION: Women in the postpartum period, notably after Cesarean delivery, may represent another new vulnerable group at increased risk for TTS. TTS in the postpartum period should be considered a clinical entity different from peripartum cardiomyopathy with specific clinical, therapeutic and prognostic implications. © 2013 Italian Federation of Cardiology
