The aim of this report is to demonstrate simple digitally controlled tooth bleaching elab protocol. To do this we used a cross polarizing filter (polar_eyes) attached to Cannon Macro Ring Lite MR-14EX flash to get the cross pollarized picture. A grey card was included in the photo (elab_card) to calibrate the photos in colour and lightness. Walking internal bleaching (Ena white regular, Micerium S.p.A., Avegno, Italy) was proceeded. At day 10 Opalescence pf 16%/ (Ultradent Products, Inc, South Jordan, UT, USA) was added to the protocol. At one-year-follow-up appointment we can calculate the rebound of ΔΕ = 3,03 but the difference between the two central incisors is ΔΕ = 1,1.

SummaryEstimating the risk of venous thromboembolism (VTE) associated with combined hormonal contraceptives following early terminated pregnancies or birth, a Danish nationwide retrospective cohort observing a one-year follow-up was defined using three unique registries. All Danish women with confirmed pregnancies aged 15–49 during the period of 1995–2009 were included. The main outcomes were relative and absolute risks of first time venous thromboembolism in users as well as non-users of combined hormonal contraceptives. In 985,569 person-years, 598 venous thromboembolisms were recorded. After early terminated pregnancies and births, respectively, 113 and 485 events occurred in 212,552 and 773,017 person-years. After early terminated pregnancies, the crude VTE incidence ratios were similar, and the numbers needed to harm were equal between groups that did or did not use combined hormonal contraceptives throughout the follow-up year. After childbirth, individuals that used combined hormonal contraceptives were more likely than non-users to experience VTE depicted by crude incidence ratios; however, the difference was only significant after 14 weeks. This implied that the numbers needed to harm were lower for those that used compared to those that did not use combined oral contraceptives in the initial 14 weeks postpartum. In conclusion, the use of combined hormonal contraceptives after early terminated pregnancies was not detrimental, but during the puerperal period, they should be used with caution.

Quality of life (QOL) has become an important focus of hernia repair outcomes. This study aims to identify factors which lead to ideal outcomes (asymptomatic and without recurrence) in large umbilical hernias (defect size ≥9 cm2). Review of the prospective International Hernia Mesh Registry was performed. The Carolinas Comfort Scale was used to measure QOL at 1-, 6-, and 12-month follow-up. Demographics, operative details, complications, and QOL data were evaluated using standard statistical methods. Forty-four large umbilical hernia repairs were analyzed. Demographics included: average age 53.6 ± 12.0 and body mass index 34.9 ± 7.2 kg/m2. The mean defect size was 21.7 ± 16.9 cm2, and 72.7 per cent were performed laparoscopically. Complications included hematoma (2.3%), seroma (12.6%), and recurrence (9.1%). Follow-up and ideal outcomes were one month = 28.2 per cent, six months = 42.9 per cent, one year = 55.6 per cent. All patients who remained symptomatic at one and two years were significantly symptomatic before surgery. Symptomatic preoperative activity limitation was a significant predictor of nonideal outcomes at one year ( P = 0.02). Symptomatic preoperative pain was associated with nonideal outcomes at one year, though the difference was not statistically significant ( P = 0.06). Operative technique, mesh choice, and fixation technique did not impact recurrence or QOL. Repair of umbilical hernia with defects ≥9 cm2 had a surprising low rate of ideal outcomes (asymptomatic and no recurrence). All patients with nonideal long-term outcomes had preoperative pain and activity limitations. These data may suggest that umbilical hernia should be repaired when they are small and asymptomatic.

The Stability

The aim of this study is to evaluate the color changes and the stability at a 1-year follow-up of white spot lesions (WSLs) treated with an infiltrating technique by using etching and TEGDMA resin. The color of 22 white spot lesions and the sound adjacent enamel (SAE) were assessed with a spectrophotometer at T0 (baseline), T1 (after treatment), and T2 (1 year after). The color change ΔE (WSLs-SAE) at T0 vs. T1 were compared to evaluate the camouflage effect efficiency, and at T1 vs. T2 to assess the stability of outcomes. To evaluate the effect on the treatment outcome of gender, the presence or not of previous orthodontic treatment, WSLs onset more/less than 10 years, the age of the patient, and the ΔE WSL (T0 vs. T1) was analyzed. The difference between ΔE (WSLs-SAE) at T0 and T1 resulted in statistical significance (p < 0.01). No statistical difference was found between ΔE (WSLs-SAE) at T1 vs. T2. The variables considered showed no statistical differences in treatment outcomes. The results of our investigation show that the technique used is immediately effective and the camouflage effect keeps up and steady one year after treatment. Such results do not appear to be influenced by analyzed clinical variables.

Epigenetic Signatures

IntroductionAnorexia nervosa (AN) is a severe psychiatric disorder. The epigenetic regulations are strongly suggested in AN. We and other groups have performed a whole-genome methylation study (methylome) in AN. We found that the differentially methylated CpG sites are located around genes involved in biological processes in link with embryonic morphogenesis, brain development and its plasticity, in particular adhesion and axon guidance. Here, we study an independent group of 40 AN patients. Furthermore, we have done a follow-up during more than one year, to compare the methylation profiles in subjects that evolve to the remission.ObjectivesOur work is to replicate the methylome study in an independent AN cohort and to characterize profiles of methylation at two times for the same subjects to compare the AN patients that convert to remitters.AimsOur goal is to identify diagnostic and prognostic epigenetic signatures for AN.MethodsOf the 40 AN patients, 18 evolved to remission. Furthermore, the blood samples of the subjects from the 2 times will be investigated, like this, each subject is its own control. Methylation of DNA is measured by using the Infinium HumanMethylation450 BeadChip technology.ResultsComparisons of AN to controls showed similar profiles of methylation involving the same biological processes as previously identified. We are comparing now the difference of methylation between the 18 remitters and the 18 actual AN, taking into account of the two times of samples.ConclusionsWe expect to characterize specific methylation signature of the prognostic of the AN remission.Disclosure of interestThe authors have not supplied their declaration of competing interest.

ABSTRACT Objective:  To assess camouflage effects by concealment of postorthodontic white-spot lesions (WSLs) to sound adjacent enamel (SAE) achieved over 12 months with resin infiltration (Icon, DMG, Hamburg, Germany). Methods:   Twenty subjects (trial teeth nteeth = 111) who had received resin infiltration treatment of noncavitated postorthodontic WSLs were contacted for a 1-year follow-up assessment of CIE-L*a*b* colors (T12). Color and lightness (CIE-L*a*b*) data for WSLs and SAE were compared to baseline data assessed before infiltration (T0) and those assessed after 6 months (T6), using a spectrophotometer. The target parameter was the difference between the summarized color and lightness values (ΔEWSL/SAE). Intergroup (WSL, SAE) and intertime comparisons (T0 vs T6, T12) were performed using paired t-tests at a significance level of α = 5%. Results:  Nine subjects (trial teeth nteeth = 49; male/female ratio 5/4; age range 13–19 years) were available at T12. After the highly significant reduction of ΔEWSL/SAE discrepancies between T0 and T6, analysis of 12-month records revealed color and lightness discrepancy of WSL vs SAE that was significantly decreased compared with baseline, indicating an assimilation of WSL color to SAE appearance after infiltration, while an additional reduction of discrepancies between T6 and T12 was not significant. Conclusion:  As color and lightness characteristics of the Icon infiltrant as well as the esthetic camouflage effects achieved by WSL infiltration were not altered significantly or clinically relevant after 12 months, the method of resin infiltration can be recommended for an enduring esthetic improvement of postorthodontic WSL.

AIM: To compare the outcome of an Ex-Press implant and subscleral trabeculectomy (SST) in the management of glaucoma after previous trabeculectomy on a fibrotic bleb. METHODS: This randomized prospective study included 28 eyes from 28 patients (age range: 42-55y) with primary open angle glaucoma (POAG) presented with elevated intraocular pressure (IOP) with fibrotic bleb despite previous SST for more than 4mo. The eyes enrolled in the study were divided into two groups: group I (subjected to Ex-Press implant surgery) and group II [subjected to SST with mitomycin C (MMC)]. The follow-up continued one year after surgery to evaluate IOP, visual acuity (VA), visual field (VF), and postoperative complications. RESULTS: A significant decrease in IOP was found in both groups with a higher reduction in Ex-Press implant surgery with the mean IOP of 14.50 mm Hg (P=0.001), while the SST group recorded the mean IOP of 16.50 mm Hg (P=0.001) after one year. However, the difference between the two groups in terms of the decrease in IOP was insignificant. Fewer postoperative complications were recorded in the Ex-Press implant surgery and more cases requiring further anti-glaucomatous medications were seen in the SST group. Both groups showed stability in terms of VA and VF. CONCLUSION: Ex-Press implant surgery and SST with MMC are two surgical alternatives for controlling IOP in late failure that occurs more than 4mo after previous SST with a fibrotic bleb. However, Ex-Press shunt is a safer surgery with fewer complications.

Abstract Background: Dental bleaching in traditional concentrations generates greater sensitivity. In this respect, new systems of lower concentration of hydrogen peroxide for tooth bleaching appeared, with color stability unknown over time. The aim of this study was to compare the change and stability of color with low-concentration (6%) hydrogen peroxide gel in an in-office bleaching setting relative to conventional 37.5% gel, including their effects on psychosocial and esthetic self-perception, after one year.Methods: Patients (n=25) were assessed at 12 months post bleaching treatment (whitening with 6% chemo-activated alkaline formula gel versus 37.5% traditional concentration gel). Color changes were measured objectively using total variation in color (ΔE), and subjectively using Vita Classical and Vita Bleached scale (ΔSGU) by calibrated evaluators (Kappa=0.85). The Psychosocial Impact of Dental Aesthetics Questionnaire (PIDAQ) and Oral Health Impact Profile (OHIP-14) aesthetic questionnaires were used to measure the self-perception and the psychosocial impact of the bleaching protocols.Results: The effect (ΔE) of 37.5% HP (8.37 ± 2.73) was significantly better than that of 6% HP (5.27 ± 2.53) in terms of color rebound after one year of follow-up. There were significant differences in psychosocial impact and esthetic self-perception measurements prior to bleaching versus one-year post-whitening time points; positive effects were maintained.Conclusions: Low concentration (6%) achieved effective bleaching with good stability after one year, accompanied by a positive psychosocial impact and enhanced self-perception at follow-up.Trial registration: NCT03217994 (before enrollment of the first participant).

Abstract Background Heavy occupational lifting is prevalent in the general working population and is sparsely reported to associate with hypertension, especially among older and hypertensive workers. We investigated if heavy occupational lifting is associated with hypertension and blood pressure (BP) in both cross-sectional and prospective study designs in the Copenhagen General Population Study, stratified by age, and use of anti-hypertensives. Methods Participation was conducted following the declaration of Helsinki and approved by the ethical committee (H-KF-01-144/01). By multivariable logistic and linear regression models, we investigated the association between heavy occupational lifting and hypertension, in a cross-sectional design (n = 67,363), using anti-hypertensives or BP ≥140/≥90 mmHg as outcome, and in a prospective design (n = 7020) with an above-median change in systolic BP (SBP) from baseline to follow-up and/or a shift from no use to use of anti-hypertensives as outcome, with and without stratification by age and use of anti-hypertensives. Results The odds ratio for hypertension was estimated at 0.97 (99% CI: 0.93–1.00) in the cross-sectional analysis, and at 1.08 (99% CI: 0.98–1.19) in the prospective analysis. The difference in SBP among workers with versus without heavy occupational lifting was estimated at − 0.29 mmHg (99% CI -0.82 – 0.25) in the cross-sectional and at 1.02 mmHg (99% CI -0.41 – 2.45) in the prospective analysis. No significant interaction between heavy occupational lifting and age, nor use of anti-hypertensives were shown. Conclusions Only the prospective analysis indicated heavy occupational lifting to increase the risk of hypertension. Further research on the association between occupational lifting and hypertension are needed.

Introduction: In terms of access to treatment of acromioclavicular joint injuries, there are many controversies, especially after the appearance of works that promote "neglecting of injury". Goal: The aim of this paper is to give a comparative analysis of the results of rehabilitation of patients after acute injury of the acromioclavicular joint of the third degree, treated by two surgical techniques: by Phemister and Vukov. Material and methods: In this study, we investigated a total of 60 operated patients: 30 patients were operated by Phemister technique, and 30 by Vukov technique. Results: Postoperative follow-up lasted for one year. Between these two groups, the time when the rehabilitation process began is significantly different p<0.01. With technique by Vukov, the rehabilitation begins on the first postoperative day and with technique by Phemister it begins later (after 7 weeks outpatient). With technique by Phemister, rehabilitation lasted on average 60 days, and with technique by Vukov on average 40 days. The duration of recovery is also significantly different p< 0.01, with technique by Vukov the duration time is shorter, and therefore the process of rehabilitation in days - is shorter than with the other technique. Both techniques gave good stability of the lateral end of clavicle. The difference was not statistically significant p> 0.05, which means that both techniques can be applied depending on the indication and the experience of the surgeon.
