Σκοπός: η αναδρομική μελέτη της αποτελεσματικότητας της μεθόδου στερεοτακτικής βιοψίας με το σύστημα BLES στην πλήρη αφαίρεση ύποπτων μαστογραφικών αποτιτανώσεων.Υλικό-Μέθοδος: μεταξύ Ιανουαρίου 2014 και Ιανουαρίου 2016, 400 στερεοτακτικές βιοψίες με τη χρήση BLES πραγματοποιήθηκαν στη μονάδα μαστού του Ιπποκράτειου νοσοκομείου λόγω ύποπτων αποτιτανώσεων σε μαστογραφία. Ο μέσος όρος ηλικίας των ασθενών ήταν 58.5 χρονών (κυμαινόμενος από 39-78 χρονών). Η συσκευή BLES χρησιμοποιεί ραδιοσυχνότητες για την αφαίρεση ιστού από το μαστό που περιλαμβάνει την υπό εξέταση βλάβη. Το καλάθι που χρησιμοποιήθηκε σε όλες τις περιπτώσεις ήταν μεγέθους 20 χιλιοστών. Εξετάστηκαν τα ιστολογικά αποτελέσματα από το παρασκεύασμα BLES και συγκρίθηκαν με τα χειρουργικά αποτελέσματα, που χρησιμοποιήθηκαν ως μέθοδος αναφοράς.Αποτελέσματα: σε 90/400 βιοψίες ανευρέθηκε καρκίνος (22.5%) και σε 38/400 βιοψίες ανευρέθηκε καλοήθης αλλοίωση με κυτταρική ατυπία (9.5%). 80% των καρκίνων ήταν DCIS και 20% διηθητικοί καρκίνοι. Το μέσο μέγεθος των αποτιτανώσεων στη μαστογραφία ήταν 15.38 χιλιοστά (st. dev.= 13.579 mm, range 3-78 mm). Πλήρης αφαίρεση των βλαβών επιτεύχθηκε σε 31/90 περιπτώσεις καρκίνων (34.4%) και σε 23/29 περιπτώσεις άτυπων αλλοιώσεων, που χειρουργήθηκαν (76.3%). Προδιαθεσικοί παράγοντες για την επιτυχή αφαίρεση των καρκίνων ήταν το μέγεθος των βλαβών (Mann Whitney test, p<0.001), η απόσταση του καρκίνου από τα όρια του ιστολογικού παρασκευάσματος (Pearson Chi-Square test, p<0.001), η παρουσία νέκρωσης comedo (Pearson Chi-Square test, p=0.014) και ο βαθμός κακοήθειας του καρκίνου (Pearson Chi-Square test, p=0.021). Το πσοστό επιτυχούς εκτομής σε καρκίνους μεγέθους <14 χιλιοστά ήταν 57.4% (31/54 περιπτώσεις). Για τις άτυπες αλλοιώσεις μόνο η απόσταση της βλάβης από τα όρια του παρασκευάσματος αποτέλεσε προδιαθεσικό παράγοντα εκτομής της βλάβης με το σύστημα BLES (p=0.031, Mann Whitney test). Το ποσοστό υποεκτίμησης ήταν 15.5% για τους καρκίνους και μηδενικό για τις περιπτώσεις άτυπων αλλοιώσεων. Το ποσοστό των συνολικών επιπλοκών ήταν 8.75%.Συμπέρασμα: Η στερεοτακτική μέθοδος BLES αποτελεί μια ασφαλή και αποτελεσματική μέθοδο βιοψίας ύποπτων μαστογραφικών αλλοιώσεων με μικρά ποσοστά υποεκτίμησης και υψηλά ποσοστά αφαίρεσης βλαβών που θα μπορούσε πιθανά να χρησιμοποιηθεί σαν θεραπευτική μέθοδο σε επιλεγμένες περιπτώσεις άτυπων βλαβών και καρκίνων καθώς επίσης και να περιορίσει την χειρουργική θεραπευτική προσέγγιση των βλαβών αυτών.

Abstract Introduction: The aim of this study was to evaluate the following parameters of fetuses and neonates with omphalocele: the prevalence of coexisting congenital heart defects (CHD), abnormalities in heart function and the impact of coexisting CHD on fetal and neonatal survival. Material and methods: The study group consisted of 69 fetuses with omphalocele diagnosed and monitored at the Department of Prenatal Cardiology in our Institute in the years 2007-2017. The retrospective analisis of patients' data was performed. For statistical analysis we used Chi-square test, t-Student test and U Mann-Whitney test.. Results: In the studied group omphalocele was an isolated defect in 31.9% of the cases (22/69), in 68.1% (47/69) coexisting defects were present, in 49.3% (34/69) the coexisting defect was CHD. The most common CHD coexisting with omphalocele were ventricular septal defect (VSD), double outlet right ventricle (DORV) and atrio-ventricular septal defect (AVSD). Abnormalities of heart function were present in 43.5% (30/69) of fetuses with omphalocele: 23.5% (8/34) with normal heart anatomy and in 62.9% (22/35) with CHD. Statistically significant differences between the group with normal heart anatomy and the group with CHD regarded: Cardiovascular Profile Score (CVPS) (median 10 points vs median 9 points, U Mann-Whitney test p=0.034), neonatal birth weight(mean 3253 g vs median 2700 g, U Mann-Whitney test p=0.003), Apgar score (median 8 vs median 7, U Mann-Whitney test p=0.038) and survival rate until discharge from hospital (85% vs 52.9%, Chi-square test p=0.034). The comparison of data from 2007-2017 with data obtained from similar analysis performed in our center in 1999-2006, revealed significant improvement in the early detection of omphalocele (median 14.5 weeks of gestation vs mean 25.4 weeks of gestation), gestational age of delivery (mean 38 weeks of gestation vs mean 34 weeks of gestation) and survival rate until discharge both in neonates with normal heart anatomy and coexisting CHD (85% and 52.9% vs 70% and 23% respectively) . Conclusions: 1. The presence of coexisting CHD is an important prognostic factor in fetuses and neonates with omphalocele, so early fetal echocardiography should be performed in every case of omphalocele. 2. During the last decade (2007-2017), in contrast to years 1999-2006, we observed significant improvement in early and complete prenatal diagnosis of omphalocele. 3. We observed improvement in strategy of obstetrical management resulting in delivering neonates in a more advanced gestational age both in the group with normal heart anatomy and the group with coexisting CHD.

Warm Vertical Compaction

This study aimed at assessing the performance of Reciproc Blue (RB) and XP Endo Shaper (XPS), used for canal retreatment on extracted teeth, in terms of debris extrusion and obturating materials removal. Thirty mandibular premolars were prepared to ProTaper X2 file, obturated using warm vertical compaction, and then incubated for 28 days at 100% humidity at 37°C. Teeth were randomly assigned into two groups, according to the system used for retreatment (RB and XPS). During retreatment, debris extruded beyond the apex was collected in preweighed Eppendorf tubes, and the retreatment time was measured. Afterward, the teeth were longitudinally sectioned to assess the remaining obturating materials. Data were statistically analyzed using the Mann–Whitney test and chi-square test at a 95% confidence level. All the samples had extruded debris at varying weights ranging from 0.125 mg to 3.680 mg. XPS extruded less debris than RB, but no difference was detected (Mann–Whitney test; P > 0.05 ). RB and XPS required 54.9 ± 17.9 and 22.3 ± 9.3 seconds to perform retreatment procedures, respectively (Mann–Whitney test; P < 0.05 ). The sealer was found in all the samples. Compared to the RB group, fewer samples with remaining gutta-percha were found in the XPS group (Chi-square test; P < 0.05 ). None of the files fractured during the retreatment procedure. The tested files appear to extrude debris beyond the apex. Although XPS was able to remove the gutta-percha completely from the majority of the canals, it was unable to remove the sealer.
