RESUMEN

BACKGROUND AND AIM: To contain the spread of COVID-19, many countries imposed several restrictive measures, leading to radical changes in daily life behaviors. Healthcare workers experienced additional stress due to the increased risk of contagion, possibly causing an increase in unhealthy habits. We investigated changes in cardiovascular (CV) risk assessed by the SCORE-2 in a healthy population of healthcare workers during the COVID-19 pandemic; an analysis by subgroups was also conducted (sportspeople vs sedentary subjects). METHODS AND RESULTS: We compared medical examination and blood tests in a population of 264 workers aged over 40, performed yearly before (T0) and during the pandemic (T1, T2). We found a significant increase in the average CV risk, according to SCORE-2, during the follow-up in our healthy population, with a shift from a mean low-moderate risk profile at T0 (2.35%) to a mean high-risk profile at T2 (2.80%). Furthermore, in sedentary subjects was observed a greater and early increase in SCORE-2 compared to sportspeople. CONCLUSIONS: Since 2019, we observed an increase in CV risk profile in a healthy population of healthcare workers, particularly in sedentary subjects, highlighting the need to reassess SCORE-2 every year to promptly treat high-risk subjects, according to the latest Guidelines.

RESUMEN

OBJECTIVES: To assess the skeletal and dental maxillary transverse compensation (yaw) on the cone beam computed tomography (CBCT) three-dimensional reconstructed image of the skull in two groups of patients, both clinically affected by a class III malocclusion with deviation of the lower midline. MATERIALS AND METHODS: An observational retrospective study was designed to analyse differences in two groups of patients, the first one was composed by patients affected by horizontal condylar hyperplasia, the second one by patients affected by dento-skeletal asymmetric class III malocclusion. Each group was composed by 15 patients. Transverse analysis was performed by measuring five landmarks (three bilateral and two uneven) with respect to a mid-sagittal plane; sagittal analysis was performed by measuring the sagittal distance on the mid-sagittal plane between bilateral points. Means were compared through inferential analysis. RESULTS: In the condylar hyperplasia group, all differences between the two sides were not statistically significant, nor for canines' difference (P = .0817), for molars (P = .1105) or for jugular points (.05871). In the class III group, the differences between the two sides were statistically significant for molars (P = .0019) and jugular points (P = .0031) but not for canines (P = .1158). Comparing the two groups, significant differences were found only for incisors' midline deviation (P = .0343) and canine (P = .0177). CONCLUSION: The study of the yaw on CBCT should be integrated into three-dimensional cephalometry and could help in differentiating the various malocclusion patterns.

RESUMEN

AIM: Temporomandibular disorders (TMD), in particular disc displacement, are recognised to have a multifactorial aetiology. Ligamentous laxity has been suggested as a potential risk factor for TMD. Ligamentous laxity can lead to generalised joint hypermobility (GJH) involving multiple joints, including the temporomandibular joint (TMJ). The aim of this work is to evaluate the correlation between GJH and disc displacement (DD) assessed on magnetic resonance images (MRI) of the TMJ in adolescent patients. MATERIALS: The study was included 40 adolescent patients (10-16 years), divided into two groups, a Study Group (SG), composed of 20 subjects with GJH, and a Control Group (CG), composed of 20 subjects without GJH. The GJH was assessed by the Beighton test with a threshold value of ≥ 4. The severity of the TMD was determined using the Fonseca Questionnaire and a clinical evaluation of the type of TMD. The condylar-discal relationship and the condylar mobility of the TMJ were evaluated by MRI. Pearson's χ2 Test was performed for the analysis of the statistical correlation. CONCLUSION: This study suggests that adolescents with GJH have a greater risk of developing TMJ disc displacement, especially disc displacement without reduction.

RESUMEN

BACKGROUND: Percutaneous coronary interventions (PCI) in calcified coronary artery lesions are associated with impaired stent expansion, higher rate of periprocedural complications and cardiac mortality. Lesion preparation using calcium modifying techniques such as Rotational Atherectomy (RA) or Intravascular Lithotripsy (IVL) has been advocated. Studies comparing these technologies are lacking. We aimed to compare in-stent pressure gradients, evaluated by vessel fractional flow reserve (vFFR), in calcific lesions treated using either RA or IVL. METHODS: Patients undergoing either RA- or IVL-assisted PCI from two European centers were included. Propensity score matching (1:2) was performed to control for potential bias. Primary outcome was post-PCI in-stent pressure gradients calculated by vFFR (vFFRgrad). Secondary outcomes included the proportion of patients with complete functional revascularization defined as distal vFFR post-PCI (vFFRpost) ≥ 0.90. RESULTS: From a cohort of 210 patients, 105 matched patients (70 RA and 35 IVL) were included. Pre-PCI vFFR did not differ between groups (0.65 ± 0.13 RA and 0.67 ± 0.11 IVL). After PCI, in-stent pressure gradients were significantly lower in the IVL group (0.032 ± 0.026 vs 0.043 ± 0.026 in the RA group, p = 0.024). The proportions of vessels with functional complete revascularization was similar between the two groups (32.9% vs. 37.1% in the RA and IVL group, respectively; p = 0.669). CONCLUSIONS: Calcific lesions preparation with IVL is effective and resulted in lower in-stent pressure gradients compared to RA. Approximately one third of the patients undergoing PCI for a severely calcified lesion achieved functional revascularization with no difference between rotational RA and IVL.

RESUMEN

BACKGROUND: Diagnosis of heart failure with preserved ejection fraction (HFpEF) in patients with dyspnea and paroxysmal atrial fibrillation (AF) is challenging. Speckle tracking-derived left atrial strain (LAS) provides an accurate estimate of left ventricular (LV) filling pressures and left atrial (LA) phasic function. However, data on clinical utility of LAS in patients with dyspnea and AF are scarce. OBJECTIVE: To assess relationship between the LAS and the probability of HFpEF in patients with dyspnea and paroxysmal AF. METHODS: The study included 205 consecutive patients (62 ± 10 years, 58% males) with dyspnea (NYHA≥II), paroxysmal AF and preserved LV ejection fraction (≥50%), who underwent speckle tracking echocardiography during sinus rhythm. Probability of HFpEF was estimated using H2FPEF and HFA-PEFF scores, which combine clinical characteristics, echocardiographic parameters and natriuretic peptides. RESULTS: Patients with high probability of HFpEF were significantly older, had higher body mass index, NT-proBNP, E/e', pulmonary artery pressure and larger LA volume index than patients in low-to-intermediate probability groups (all p < 0.05). All components of LAS and LA strain rate showed proportional impairment with increasing probability of HFpEF (all p < 0.05). Out of the speckle tracking-derived parameters, reservoir LAS showed the largest area under the curve (AUC = 0.78, p < 0.001) and the strongest independent predictive value (OR: 1.22, 95% CI 1.08-1.38) to identify patients with high probability of HFpEF. CONCLUSIONS: Reservoir LAS shows a high diagnostic performance to distinguish HFpEF from non-cardiac causes of dyspnea in symptomatic patients with paroxysmal AF.

RESUMEN

AIM: The aim of research is to show the effectiveness of 0.014X0.025 CuNiTi wires in self-ligating straight-wire appliance in the working time of 10 weeks, the treatments are monitored with the Dental Monitoring® Applications. A statistical significance analysis of the correspondence between the results of the first phase of fixed orthodontic treatment (alignment), according to the type of wires used, compared to the time (about 8 weeks) suggested by the manufactory house is therefore useful to fully understand the power of these arches in the orthodontic treatment. MATERIAL AND METHODS: The study provides for the recruitment of 35 cooperating patients with different degrees of crowding, all treated with Damon System(ORMCO), monitoring them through pictures, taken in the Dental Monitoring(DM®) sequence technique, as follows: Time0: Arch-Wire Insertion (0.014x0.025CuNiTi), Time1: Four Weeks, Time2: Eight Weeks, Time3: Ten Weeks. RESULT: The results obtained will be compared with records reported by manufactory house. Our results showed that the manufacture information does not correspond to the real efficiency of the device tested. Statistical Analyses performed by T test student. CONCLUSIONS: In Our experience, applying DM Application with self-ligating technique has reduced in term of number of appointments for each patient from 3 appointments in 10 weeks to 2 appointments, when the indirect bonding was effectuated and when we have inserted a 014X025 CuNiTi. This means that there is a reduction in the mean period of chair time, of material 'costs, number of visits; moreover, there is an increase in term of frequency of patient' s monitoring, resulting in a more precise evaluation of treatment by orthodontist. The limits of the present study are presented by the variable patient's compliance and by the small number of patients. This device is an instrument advantageous for the orthodontist's work. In literature, there are few articles inherent to Digital application Mobile, we will hope that this our experience represents a valid support to a major use of this application in the clinical practice.

RESUMEN

BACKGROUND: To evaluate the relationship between gender, ethnicity/citizenship, clinical phenotype, total prevalence, and the various congenital malformations associated with oral clefts (OC) in Italy across the period 2001-2014. METHODS: A retrospective analysis (2001-2014) was conducted based on the National Congenital Malformation Registries network of Italy (Emilia-Romagna Registry of Birth Defects [IMER] and Registro Toscano Difetti Congeniti [RTDC]), which were analyzed to investigate time trends, geographical/ethnic clusters, topography, sex ratio, and associated congenital anomalies of OC phenotypes. RESULTS: Among 739 registered cases, 29.8% were syndromic or had multi-malformed associated anomalies, compared with 70.2% having isolated orofacial cleft. Cleft lip (CL) was observed in 22%, cleft palate (CP) in 40%, and cleft lip and palate (CLP) in 38% of live births, stillbirths, and terminations of pregnancy for fetal anomaly cases. Other associated conditions were major anomalies of cardiovascular defects (39%), followed by defects of the limbs (28%), neuroectodermal defects (23%), and urogenital malformations (10%). Male-to-female sex ratio was 1:1.14 in CP, 1.22:1 in CL, and 1.9:1 in CLP. Foreigners were represented by 29% from Southeast Asia, 25% from Balkans, 25% from North-Central Africa, 9% from the East, 7% from Western Europe, and 5% from South America. Total prevalence of OC cases ranged from 0.9 (RTDC) to 1.1 (IMER) of 1000 births. CONCLUSIONS: This retrospective study provides a population-based, clinical-epidemiological description of the orofacial cleft phenomenon. As a relatively frequent congenital malformation, its social and economic impact is worthy of further study. These abnormalities can cause significant problems that may be solved or minimized by early diagnosis and treatment.

RESUMEN

INTRODUCTION: Temporomandibular disorders (TMD) are an heterogeneous group of disorders affecting temporomandibular joints (TMJ), masticatory muscles, or both. The aim of this study is to evaluate the relationship between general health and psychological distress variables and the clinical diagnosis of TMD in children between 8 - 13 years old. Moreover, it will be underlined the different perception of psychological distress existing between patients and their parents. MATERIALS AND METHODS: Patients were divided in two groups: the "case group", which includes patients with TMD, and the "control group", which included patients asymptomatic for TMD. The "case group" is composed by 29 patients, while the "control group" is composed by 22 patients. The patients were asked to fill in a questionnaire called Child Health Questionnaire (CHQ), to evaluate general health and psychological condition and, eventually, the presence of symptoms of stress, anxiety and/or depression. The CHQ is 87 - item questionnaire developed in USA specifically for children. RESULT: As widely reported during the present work, the link between TMD and psychological distress is existing and quite strong, because of lack of number of patients many aspects worth of attentions have not been analyzed as they deserved. CONCLUSION: That's way the conclusion must lead to the proposal of going on with the present study following, possibly, some aspects of research as an increase of the number of patients involved in the study; Individuate possible elements, internal and external, that could strongly influence differences between patient's results and parent's results, etc.

RESUMEN

AIM: To analyse the presence and prevalence of gnathologic problems in a sample of children, candidate for orthodontic treatment, and evaluate the relationship between psychological factors and gnathological problems. The purpose of this study was also to evaluate a simple protocol with specific psychological test and a questionnaire for the rapid diagnosis of gnathologic problems, useful for possible screening studies on a wider population. MATERIALS AND METHODS: Study Design: Observational, cross-sectional study. Among the patients coming for a first orthodontic evaluation 106 children, aged between 8 and 16 years, were examined. A complete orthodontic evaluation was performed in all patients; the RCMAS (Revised Children's Manifest Anxiety Scale) was used in the study to test the psychological condition, while the selected test for the diagnosis of gnathologic problems was the Fonseca Test. The prevalence of temporomandibular disorders (TMD) was evaluated with descriptive statistical analysis, and the eventually present correlation with a positive psycological test for anxiety has been evaluated with correlation parameters: c2 test of Pearson, and Cramer's V index. RESULTS: The mean age of the children was 10.74 years. Females accounted for 55.66% of the total compared to 44.34% males. Signs and symptoms of TMD were present on average in 82% and 32% respectively. A remarkable amount of children also showed signs of psychological problems, mostly represented by anxiety. Positive correlation resulted between TMD (Fonseca scores) and increased overbite. Cross-correlations have been obtained, tested with Pearson c2 test and Cramer's V index, between level of anxiety, muscle pain on palpation, bad habits, and headache. The Class II subdivision molar class and altered canine relationship have been related to the presence of articular noise. CONCLUSION: The protocol largely respected the need for speed of administration, comprehensiveness and reliability that we set out to achieve. Limited correlations have been assessed between occlusal conditions and positivity to the administrated tests. Further studies are desirable to increase the sample population.

RESUMEN

INTRODUCTION: Cleidocranial dysplasia (CCD) is an inherited disease caused by mutations in the RUNX2 gene on chromosome 6p21. This pathology, autosomal dominant or caused by a spontaneous genetic mutation, is present in one in one million individuals, with complete penetrance and widely variable expressivity. AIM: To identify the incidence of these clinical findings in the report of the literature by means of PubMed interface from 2002 to 2015, with the related keywords. The report of local patients presents a clinical example, related to the therapeutic approach. RESULTS AND DISCUSSIONS: The PubMed research resulted in 122 articles. All the typical signs were reported in all presented cases. The maxilla was hypoplastic in 94% of the patients. Missing of permanent teeth was found in two cases: one case presented a class II jaw relationship, instead of class III malocclusion. Similar findings were present in our cohort. CONCLUSION: CCD is challenging for both the dental team and the patient. The treatment requires a multidisciplinary approach. Further studies are required to better understand the cause of this disease. According to this review, a multistep approach enhances the possibilities to achieve the recovery of the most possible number of teeth, as such to obtain a good occlusion and a better aesthetic.

RESUMEN

This study was performed to evaluate the reliability of peri-apical radiographs in determining peri-implant marginal bone level changes. The STROBE guidelines were followed. Marginal bone levels were measured at the time of implant insertion using a straight periodontal probe and using peri-apical radiographs. These intraoperative and radiographic measurements were repeated at the time of second surgery. All radiographs were analysed by two examiners blinded to the intraoperative measurements. To standardize the radiographic images, the long-cone parallel technique and a film-holding system were used. Intra-observer agreement and inter-observer variability were assessed using the intra-class correlation coefficient (ICC). Descriptive statistics, the t-test, and the Pearson correlation coefficient were also used. A total of 268 implants were inserted in 142 patients. Inter-observer agreement was 0.950; intra-observer variability was 0.980 and 0.973. The mean difference between the radiographic and intraoperative measurements was 0.50±1.55mm (range 0-8mm); the difference was statistically significant (P=0.000). A significant linear correlation was found between the marginal bone level changes evaluated intraoperatively and radiographically (P<0.005). Radiographic analysis significantly overestimated the level of peri-implant marginal bone compared to intraoperative measurements, but peri-apical radiographs are reliable in determining the bone level changes at different follow-ups.

RESUMEN

The aim of this report was to describe a new computer-guided technique for a controlled site preparation and palatal orthodontic miniscrew insertion using a dedicated software. A surgical guide was designed after planning the appropriate insertion sites on three-dimensional images created by the fusion of cone-beam computed tomography (CBCT) and digital dental model images. Pre- and postoperative CBCT images were compared and the angular, coronal, and apical deviations between the planned and the placed miniscrews were calculated. The mean coronal and apical deviations were 1.38mm (range: 3.48-0.15mm; standard deviation (SD): 0.65) and 1.73mm (range: 5.41-0.10mm; SD: 1.03), respectively, while the mean angular deviation was 4.60° (range: 15.23-0.54°; SD: 2.54). The present surgical guide allows a controlled and accurate palatal miniscrew placement in three dimensions.

RESUMEN

High platelet reactivity (PR) values on treatment with clopidogrel are associated with an increased rate of thrombotic events after a percutaneous coronary intervention (PCI). However, we do not know the optimal timing of the performance of the PR measurements. Platelets might be activated during a PCI, which means that the timing of PR measurements, before or after PCI, could influence the outcome. In turn, this could lead to misinterpretation of the patient's response to antiplatelet therapy and a less accurate prediction of the patient's risk of thrombotic events during follow-up. We aimed to evaluate the effect of stent implantation on PR in patients with and without acute coronary syndromes who undergo PCI to assess the optimal timing of PR measurements. A systematic literature search was performed and the results are summarized in this review.

RESUMEN

BACKGROUND: The prevalence of impacted maxillary canine is reported to be between 1% and 3%. The lack of monitoring and the delay in the treatment of the impacted canine can cause different complications such as: displacement of adjacent teeth, loss of vitality of neighbouring teeth, shortening of the dental arch, follicular cysts, canine ankylosis, recurrent infections, recurrent pain, internal resorption of the canine and the adjacent teeth, external resorption of the canine and the adjacent teeth, combination of these factors. An appropriate diagnosis, accurate predictive analysis and early intervention are likely to prevent such undesirable effects. The objective is to evaluate, by means of a retrospective observational study, the possibility of carrying out a predictive analysis of root resorption adjacent to the impacted canines by means of orthopantomographs, so as to limit the prescription of additional 3D radiography. MATERIAL AND METHODS: 120 subjects with unilateral or bilateral maxillary impacted canine were examined and 50 patients with 69 impacted maxillary canine (22 male, 28 female; mean age: 11.7 years) satisfied the inclusion criteria of the study. These patients were subjected to a basic clinical and radiographic investigation (orthopantomographs and computerized tomography). All panoramic films were viewed under standardized conditions for the evaluation of two main variables: maxillary canine angulations (a, b, g angles) and the overlapping between the impacted teeth and the lateral incisor (Analysis of Lindauer). Binary logistic regression was used to estimate the likelihood of resorbed lateral incisors depending on sector location and angle measurements. RESULTS: Results indicated that b angle has the greatest influence on the prediction of root resorption (predictive value of b angle = 76%). If ß angle <18° and Lindauer = I, the probability of resorption is 0.06. CONCLUSIONS: Evaluation of b angle and superimposition lateral incisor/impacted canine analysed on orthopantomographs could be one of the evaluation criteria for prescribing second level examination (CT and CTCB) and for detecting root resorption of impacted maxillary canine adjacent teeth.

RESUMEN

The aim of this prospective study was to evaluate the effectiveness of an innovative, minimally invasive, flapless corticotomy procedure in orthodontics. The STROBE guidelines were followed. Ten patients with severe dental crowding and a class I molar relationship were selected to receive orthodontic treatment with clear aligners and corticotomy-facilitated orthodontics. The mean age of these patients was 21 years (range 17-28, standard deviation 6.08 years); the male to female ratio was 2:1. The main outcome was a reduction in the total treatment time to correct dental crowding. The secondary outcomes were periodontal index changes, the degree of root resorption, and patient perceptions of the method used, assessed using the short-form Oral Health Impact Profile (OHIP-14). The occurrence of early surgical complications or unexpected events was also recorded. All patients completed the treatment to correct dental crowding. The average treatment time was reduced by two-thirds. The procedure did not significantly modify the periodontal indices or oral health-related quality of life. No early surgical complications or unexpected events were observed. In short, the results indicate that this new procedure is safe and accelerates tooth movement without periodontal complications or discomfort. However, the efficacy of this procedure must be confirmed in controlled clinical trials.

RESUMEN

OBJECTIVE: The aim of this study was to evaluate the possible influence of a malocclusion pattern on a patient's posture. METHODS: Patients affected by symmetric malocclusion or malocclusion with mild to moderate non-syndromic craniofacial asymmetry were submitted to a clinical and X-ray evaluation. Subjects with symmetric skeletal class I were used as the control group. Evaluation of differences in postural pattern was performed using rasterstereography. RESULTS: Statistical analysis (t-test) was performed on 61 patients divided in homogeneous subgroups. The results show a pelvic torsion angle of 1.08° + 3.00° (P = 0.0023) (normal value (NV) = 0.0-1.9°) in subjects presenting skeletal class II z asymmetry (control group: 1.17° ± 1.25°, not significant (NS)). CONCLUSIONS: The present study shows evidence of a relationship between malocclusion and spinal posture. A better understanding of the relationship between malocclusion and posture may help in planning a multidisciplinary approach that could involve other specialists.

RESUMEN

Toll-like receptors (TLR) are essential for the innate immune response against invading pathogens and have been described in immunocompetent cells of areas affected by periapical disease. Besides initiating the inflammatory response, they also directly regulate epithelial cell proliferation and survival in a variety of settings. This study evaluates the in situ expression of TLR4 in periapical granulomas (PG) and radicular cysts, focusing on the epithelial compartment. Twenty-one periapical cysts (PC) and 10 PG were analyzed; 7 dentigerous non-inflamed follicular cyst (DC) served as control. TLR4 expression was assessed by immunohistochemistry. TLR4 immunoreaction products were detected in the epithelium of all specimens, with a higher percentage of immunostained cells in PG. Although TLR4 overexpression was detected in both PG and PC, there were differences that seemed to be related to the nature of the lesion, since in PG all epithelial cells of strands, islands and trabeculae were strongly immunoreactive for TLR4, whereas in PC only some areas of the basal and suprabasal epithelial layers were immunostained. This staining pattern is consistent with the action of TLR4: in PG it could promote formation of epithelial cell rests of Malassez and in epithelial strands and islands the enhancement of cell survival, proliferation and migration, whereas in PC TLR4 could protect the lining epithelium from extensive apoptosis. These findings go some way towards answering the intriguing question of why many epithelial strands or islands in PG and the lining epithelium of apical cysts regress after non-surgical endodontic therapy, and suggest that TLR4 plays a key role in the pathobiology of the inflammatory process related to periapical disease.
