The "European Mandibular Angle" Research Project: The Epidemiologic Results From a Multicenter European Collaboration.

PURPOSE: The aim of this study was to analyze the demographic variables and causes and characteristics of mandibular angle fractures managed at several European departments of maxillofacial surgery. MATERIALS AND METHODS: This study was based on a multicenter systematic database that allowed the recording of data from all patients with mandibular angle fractures between January 1, 2013, and December 31, 2017. The following data were recorded: gender, age, etiology, side of angle fracture, associated mandibular fractures, presence of third molar, intermaxillary fixation, and osteosynthesis. RESULTS: The study included 1,162 patients (1,045 male and 117 female patients). A significant association was found between the presence of a third molar and the diagnosis of an isolated angle fracture (P < .0000005). Furthermore, assaults were associated with the presence of voluptuary habits (P < .00005), a younger mean age (P < .00000005), male gender (P < .00000005), and left-sided angle fractures (P < .00000005). CONCLUSIONS: Assaults and falls actually represent the most frequent causes of angle fractures. The presence of a third molar may let the force completely disperse during the determination of the angle fracture, finding a point of weakness.

Predictive role of the Mediterranean diet on mortality in individuals at low cardiovascular risk: a 12-year follow-up population-based cohort study.

BACKGROUND: Adherence to the Mediterranean diet reduces the risk of all-cause and cardiovascular (CV) mortality and the incidence of CV events. However, most previous studies were performed in high-risk individuals. Our objective was to assess whether the adherence to the Mediterranean diet, evaluated by the MED score, was associated with all-cause and CV mortality and incidence of CV events in individuals at low CV risk from a population-based cohort, after a 12-year mean follow-up. METHODS: A cohort of 1658 individuals completed a validated food-frequency questionnaire in 2001-2003. The MED score was calculated by a 0-9 scale. Anthropometric, laboratory measurements, and the vital status were collected at baseline and during 2014. The baseline CV risk was estimated by the Framingham risk score. Participants were divided into two groups: individuals at low risk (CV < 10) and individuals with CV risk ≥ 10. RESULTS: During a 12-year mean follow-up, 220 deaths, 84 due to CV diseases, and 125 incident CV events occurred. The adherence to the Mediterranean diet was low in 768 (score 0-2), medium in 685 (score 4-5) and high in 205 (score > 6) individuals. Values of BMI, waist circumference, fasting glucose and insulin significantly decreased from low to high diet adherence only in participants with CV risk ≥ 10. In a Cox-regression model, the hazard ratios (HRs) in low-risk individuals per unit of MED score were: HR = 0.83 (95 % CI 0.72-0.96) for all-cause mortality, HR = 0.75 (95 % CI 0.58-0.96) for CV mortality, and HR = 0.79 (95 % CI 0.65-0.97) for CV events, after multiple adjustments. In individuals with CV risk ≥ 10, the MED score predicted incident CV events (HR = 0.85; 95 % CI 0.72-0.99), while the associations with all-cause (HR = 1.02; 95 % CI 0.90-1.15) and CV mortality (0.94; 95 % CI 0.76-1.15) were not significant. CONCLUSIONS: Greater adherence to the Mediterranean diet was associated with reduced fatal and non fatal CV events, especially in individuals at low CV risk, thus suggesting the usefulness of promoting this nutritional pattern in particular in healthier individuals.

Promoting healthy lifestyle habits among participants in cancer screening programs: Results of the randomized controlled Sti.Vi study.

Background: Unhealthy diets, physical inactivity, alcohol and tobacco consumption are among the leading risk factors for non-communicable diseases. It is estimated that around 40% of cancers could be prevented by adopting healthy lifestyles. Design and methods: The Stili di Vita (Sti.Vi) study was a randomized study for assessing the impact of healthy lifestyle interventions on anthropometric measures, metabolic parameters, and health outcomes among participants of cancer screening programs in Turin (Italy). Eligible women aged 50-54 years, invited to biennial mammography screening, and 58-years-old men and women, invited to a once-only sigmoidoscopy for colorectal cancer (CRC) screening were randomly allocated to Diet group (DG), Physical Activity group (PAG), Physical Activity plus Diet group (PADG), or control group (CG). Physical and eating habits, metabolic and anthropometric measurements, repeatedly collected, were the study outcomes. The active intervention, offered to participants assigned to the DG, PAG, and PADG arms, consisted of a basic module and an advanced module. The effect of the interventions was estimated through logistic regression or a difference in differences approach. A multiple imputation procedure was implemented to deal with missing values and q-values have been calculated in the presence of multiple hypothesis testing. Results: Out of the 8442 screened attendees, 1270 signed informed consent, while 1125 participants accomplished the baseline visit. Participants were equally distributed across the four treatments as following: 273 (24.3%) in DG, 288 (25.6%) in the PAG, 283 (25.1%) in PADG, and 281 (25%) in the CG. Participants assigned to DG or PADG increased their consumption of whole grains (OR = 1.77, 95% CI: 1.20-2.60 and OR = 1.55, 95% CI: 1.06-2.27, respectively) and legumes (OR = 1.77, 95% CI: 1.12-2.79 and OR = 2.24, 95% CI: 1.41-3.57, respectively), with respect to CG. The participants randomized to DG reduced processed meat and increased fruit consumption (OR = 2.57, 95% CI: 1.76-3.76 and OR = 2.38, 95% CI: 1.12-5.06, respectively). The effects were more evident in the CRC screening subgroup. No relevant difference was observed between PAG and CG. No impact was observed on physical activity habits. Conclusions: Our findings suggest that active interventions can increase awareness and induce diet changes. However, participation rate and compliance to the courses was quite low, innovative strategies to enhance participants' retention are needed, with the ultimate goal of increasing awareness and inducing positive lifestyle changes.

The use of optical scanner for the fabrication of maxillary obturator prostheses.

INTRODUCTION: Maxillectomy following tumors or, more rarely, traumatic injuries may result in maxillary defects that may determine physical dysfunctions and functional impairment of speech and swallowing. The aim of our study was to present our experience in the management of post-maxillectomy patients by the use of obturator prostheses that were obtained by 3D digital casts via an intraoral scanner. METHODS: Patients with maxillary defects following maxillary and/or palatal resection or maxillary traumatic avulsion were selected for this clinical study between 2015 and 2018. Five to 6 months after surgery, a definitive obturator prosthesis was fabricated thanks to an intraoral scanner. The following parameters of clinical outcome were considered: the absence of fluid leakage, the recovery of phonation, the recovery of swallowing, and personal satisfaction. RESULTS: Twenty-eight patients (20 males, 8 females) fulfilled the inclusion criteria and were included in the study. Most patients had a maxillary and/or palatal defect because of a malignant tumor. On the whole, 93% of patients reported a complete absence of fluid leakage between maxillary sinuses or nasal fossa and oral cavity; most patients reported a good or complete recovery of phonation and swallowing. CONCLUSIONS: Digital technology for the fabrication of maxillary obturator prosthesis may be effective and useful. The reduced laboratory working time, the avoidance of the risk of aspiration of impression materials, and the overcome of the difficulties associated with whole tissue undercut impression are just some of the most important advantages that have been encountered thanks to this promising technology.

The relationship between the status and position of third molars and the presence of mandibular angle and condylar fractures.

INTRODUCTION: The aim of this study was to assess the relationship between the status and position of third molars, and the presence of mandibular angle and/or condylar fractures, in a group of patients treated for mandibular fractures, thus hoping to contribute to the knowledge of potential predictors of these fractures. METHODS: A retrospective study was designated to include all the patients who were diagnosed and treated with open reduction and internal fixation for isolated mandibular angle fractures or isolated mandibular condylar fractures between 1st of January 2012 and 31st of December 2018. The following data were collected for each included patient: gender, age, etiology, site and side of the fracture, and presence and eruption state of third molars in the fracture side. RESULTS: Seventy patients were diagnosed with a condylar fracture, 48 with an angle fracture. No statistically significant difference was observed as for etiology and gender distribution between angle fracture and condyle fracture patients (p > 0.05). Angle fractures were statistically associated with the presence of third molars, whereas condylar fractures with the absence of third molars (p < 0.000005). The presence of completely erupted 3Ms was associated with condylar fractures (p < 0.05), and partially impacted 3Ms were associated with angle fractures (p < 0.0005). CONCLUSIONS: Mandibular angle fractures and third molar presence are associated in patients who present with mandibular fractures, especially if the third molar is incompletely erupted. This information should be kept in consideration as for the diagnosis and management of patients with mandibular fractures.

The potentialities of the Anatomage Table for head and neck pathology: medical education and informed consent.

INTRODUCTION: The understanding of anatomy of head and neck region and of the relative pathological conditions may be challenging for most medical students. Furthermore, patients may encounter great difficulties to understand their pathology, the proposed surgical technique, as well as the anatomy of this body district. The purpose of the present study was to present and discuss the use of the Anatomage Table for the assessment of several benign and malignant conditions of head and neck district. MATERIALS AND METHODS: The hospital database of Novara University Hospital, Novara, Italy, was searched for odontogenic keratocysts, thyroglossal duct cysts, and oral squamous cell carcinomas. A case for each pathology was randomly chosen, and preoperative computed tomography (CT) scans (in DICOM files) were retrieved. The DICOM data of preoperative CT examinations were uploaded in the Anatomage Table device, and an immediate 3-D reconstruction image was obtained from the Anatomage Table. Then, a workstation was used to obtain images of the body surface, "dissection cuts," or "vascular reconstructions," by the variations of the filters. RESULTS: The "dissection," "vascular," and "bony" images of three cases of odontogenic keratocyst, thyroglossal duct cyst, and mandibular oral squamous cell carcinoma were produced and presented. DISCUSSION: The examination of the different slices and the application of different filters represent a promising tool both for the education of students/residents and for an improved informed consent by the patients.

Vive la Difference! The Effects of Natural and Conventional Wines on Blood Alcohol Concentrations: A Randomized, Triple-Blind, Controlled Study.

Different alcoholic beverages can have different effects on blood alcohol concentration (BAC) and neurotoxicity, even when equalized for alcohol content by volume. Anecdotal evidence suggested that natural wine is metabolized differently from conventional wines. This triple-blind study compared the BAC of 55 healthy male subjects after consuming the equivalent of 2 units of alcohol of a natural or conventional wine over 3 min in two separate sessions, one week apart. BAC was measured using a professional breathalyzer every 20 min after consumption for 2 h. The BAC curves in response to the two wines diverged significantly at twenty minutes (interval T20) and forty minutes (interval T40), and also at their maximum concentrations (peaks), with the natural wine inducing a lower BAC than the conventional wine [T20 = 0.40 versus 0.46 (p < 0.0002); T40 = 0.49 versus 0.53 (p < 0.0015); peak = 0.52 versus 0.56 (p < 0.0002)]. These differences are likely related to the development of different amino acids and antioxidants in the two wines during their production. This may in turn affect the kinetics of alcohol absorption and metabolism. Other contributing factors could include pesticide residues, differences in dry extract content, and the use of indigenous or selected yeasts. The study shows that with the same quantity and conditions of intake, natural wine has lower pharmacokinetic and metabolic effects than conventional wine, which can be assumed due to the different agronomic and oenological practices with which they are produced. It can therefore be hypothesized that the consumption of natural wine may have a different impact on human health from that of conventional wine.

The use of teleradiology for triaging of maxillofacial trauma.

PURPOSE: The aim of this study was to assess and discuss our experience with a teleradiology technique applied to facial trauma patients referred to an oral and maxillofacial surgery hub center. MATERIALS AND METHODS: All trauma patients with maxillofacial fractures from the hospitals of Vercelli, Biella, Borgosesia, Borgomanero, Verbania, and Domodossola who were referred between July 2014 and September 2018 to the hub maxillofacial center of Novara were reviewed. The following data were recorded for each patient: sex, age, referral hospital, etiology, etiology mechanisms, site of facial fractures, date of injury, indications for surgery according to teleradiology consultation, indications for surgery following clinical maxillofacial assessment, date of eventual surgery, timing of surgery from trauma, type of surgical intervention. RESULTS: A total of 467 patients with a total of 605 fractures were triaged and managed by the Tempore telemedicine system. The most frequent cause of maxillofacial injury was fall. The most frequently observed fracture involved the zygoma. Following remote computed tomography assessment, surgical indications were suggested in 68 patients; 223 patients were not considered suitable candidates for surgery; and 176 patients needed a clinical assessment for the establishment of definitive eventual indications for surgery. Following clinical assessment, the absence and presence of surgical indications was confirmed in all 223 and 68 patients, respectively. Within the 176 patients with "possible" surgical indications, only 27 patients were referred for surgery. CONCLUSION: Teleradiology may be helpful for an appropriate triaging of trauma patients from peripheral hospitals for the correct referral to a maxillofacial trauma hub center.

The "European Mandibular Angle" research project: the analysis of complications after unilateral angle fractures.

OBJECTIVE: The aim of this study was to analyze the complications and outcomes of surgical treatment of angle fractures managed at departments of maxillofacial surgery in several European countries. STUDY DESIGN: Patients hospitalized with unilateral isolated angle fractures between 2013 and 2017 were included. The following data were recorded: gender and age of patients, fracture etiology, presence of the third molar, maxillomandibular fixation, osteosynthesis technique, and complications. RESULTS: In total, 489 patients were included in the study. The Champy technique was found to be the most frequently chosen osteosynthesis technique. Sixty complications were observed, at a rate of 12.3%. Complications were associated with the absence of third molars (P < .05). Instead, the Champy technique was associated with fewer complications (P < .05), in comparison with the other adopted techniques. CONCLUSIONS: The management of angle fractures still represents a challenging task with a significant complication rate. The Champy technique still seems to be a valid option for the treatment of such injuries.

Assessing the appropriateness of parenteral nutrition use in hospitalized patients. A comparison on parenteral nutrition bag prescription in different wards and nutritional outcomes.

PURPOSE: Our aim is to assess parenteral nutrition (PN) bag prescription in hospitalized patients and evaluate clinical outcomes linked to PN therapy. METHODS: We performed an observational longitudinal retrospective study on PN prescription in a General Public Hospital in Turin, Italy, on ninety-five patients receiving PN prescribed by the Nutrition Support Team (NST). We described patients' demography and assessed nutritional outcomes, as well as PN bag prescription in different wards. Medians were calculated for several clinical parameters before and after PN therapy. A z-test for proportions has been performed to better understand the impact of various conditions on clinical outcomes and to compare differences between administered nutrients and required amounts. RESULTS: The NST resulted responsible for only 18% of bags prescribed in the geriatrics ward and for 48% in the surgery wards. PN was not able to fulfill nutritional requirements resulting in a median lack of 3.1 calories and 0.23 g of proteins per kilogram of reference body weight per day. Despite this, PN therapy was able to improve total blood proteins and calcium blood levels in our cohort. The NST changed the prescription in 55.8% of the pre-existing PN regimens. CONCLUSIONS: More strict adherence to guidelines is needed in order to maximize effectiveness of PN and observe a positive impact on clinical parameters.

Food Safety and Sustainable Nutrition Workshops: Educational Experiences for Primary School Children in Turin, Italy.

European control and prevention policies are focused to guarantee a high level of protection of consumers' health. Food-borne diseases as obesity, diabetes, food allergy, and food-borne outbreaks are increasing. To prevent food-borne diseases, it is fundamental to involve consumers, in particular children, in educational experiences aimed to learn the proper behaviours to be applied. In this context, we designed and performed 5 educational workshops about food safety, hidden allergens in food and nutrition aimed to involve children attending primary and summer school. These experiences let us collect observations about children knowledge and behaviours. From May to October 2015, a total of 1708 children aged 6 to 11 years joined our workshops. Children were involved in listening activities, laboratory experiments, handling games and sensory experiences. All participants were familiar with food allergy and were interested to know how to behave with allergic people. Children showed great curiosity in discovering that many foods normally contain live bacteria. Less than 25% of children reported to skip breakfast, to have it watching TV or to spend few minutes for it. Many of them (>75%) thought that fruits and vegetables are all year-round available and are not related to a specific period. Very few participants (<25%) knew that freezing is the treatment to be applied to make fresh fish safe from parasites. Children involved in food safety and nutrition educational experiences have the opportunity to increase their awareness about the correct behaviours to prevent food-borne diseases and to improve their own critical thinking about food consumption.

[Low protein dinner: patients in the kitchen]. / Cena ipoproteica: i pazienti cucinano.

INTRODUCTION: Diet therapy is important in renal failure to slow down the progression of the nephropathy and to control uremic symptoms. The main barrier is long-term poor compliance because of flavour and appetizing of a low protein meal. METHODS: We organized an educational cooking event in a kitchen laboratory with a chef.Fifty patients came accompanied by their care-giver. They could listen to the chefs advices, observe the manipulation of food, taste the dishes prepared with low protein products and directly cook with the assistance of the chef. The menu consisted of appetizers, two different kinds of pasta dishes, a vegetable dish, olive bread and a dessert.The patients collaborated to prepare bread and pasta. CONCLUSIONS: Patients appreciated the event and participated in an active way. They showed how important is their direct participation in the control of the disease.
