A Multicentric Prospective Study on Maxillofacial Trauma Due to Road Traffic Accidents: The World Oral and Maxillofacial Trauma Project.

ABSTRACT: The purpose of this prospective multicenter study was to analyze the epidemiology, patterns, and management of maxillofacial fractures due to road traffic accidents (RTAs) worldwide.Between Monday September 30, 2019 and Sunday October 4, 2020,1066 patients with RTAs related fractures were admitted to 14 maxillofacial surgery departments. The following data were analyzed: age, gender, mechanism of injury, alcohol or drug abuse at the time of trauma, maxillofacial fracture site, facial injury severity scale (FISS) score, associated injuries, day and month of trauma, time of treatment, type of treatment and length of hospital stay. Data were analyzed using bivaried and multivaried statistical analysis.Eight hundred seventy patients were male, and 196 were female. The most common mechanism of injury was motorcycle accidents (48%). More than half of the patients had fractures of the middle third of the maxillofacial skeleton. In total, 59% of the study sample underwent open reduction internal fixation. The median facial injury severity scale (3 points) and the medial hospital stay (3 days) were significantly lower in patients with seatbelts and helmet (P  < 0.001).This first prospective, multicenter epidemiological study shows that motorcycle accidents are the leading cause of RTAs related fractures, mostly in young males. Particularly in Australia and Europe, the incidence of RTAs was significantly lower. Moreover, this study found that the severity of maxillofacial lesions was significantly higher in patients without safety devices, with consequent longer hospital stay demonstrating the efficacy of road safety policies in preventing maxillofacial injury.

World Oral and Maxillofacial Trauma (WORMAT) project: A multicenter prospective analysis of epidemiology and patterns of maxillofacial trauma around the world.

BACKGROUND/AIM: The World Oral Maxillofacial Trauma (WORMAT) project was performed to analyze the causes and characteristics of maxillofacial fractures managed in 14 maxillofacial surgery divisions over a 1-year period. METHODS: The following data were collected: age, sex, cause and mechanism of maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score (FISS), associated injury, day of trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software. RESULTS: Between 30 September 2019 and 4 October 2020, 2,387 patients (1,825 males and 562 females [ratio 3.2:1], 47.6% aged 20-39 years [mean age 37.2 years, median 33.0 years]) were hospitalised. The main cause of maxillofacial fracture was road traffic accidents (RTA), which were statistically associated with male adults as like as assault, sport, and work (p<0,05). Half of the fractures involved the middle third of the face, statistically associated with fall and assault (p<0.05). Trauma in multiple locations was significantly associated with longer hospital stay (p<0.05). The mean length of hospitalization was 3.9 days (95% Confidence Interval 3.7-4.2). CONCLUSIONS: This prospective, multicenter epidemiological study confirmed that young adult males were the ones most commonly affected by maxillofacial fracture. RTAs and assaults are statistically associated with the adult population, while falls are associated with females and older population.

A multicentric, prospective study on oral and maxillofacial trauma in the female population around the world.

BACKGROUND/AIMS: Approximately 20% of patients with maxillofacial trauma are women, but few articles have analysed this. The aim of this multicentric, prospective, epidemiological study was to analyse the characteristics of maxillofacial fractures in the female population managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (0-18, 19-64, or ≥65 years), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment, and length of hospitalization. RESULTS: Between 30 September 2019 and 4 October 2020, 562 of 2387 patients hospitalized with maxillofacial trauma were females (24%; M: F ratio, 3.2:1) aged between 1 and 96 years (median age, 37 years). Most fractures occurred in patients aged 20-39 years. The main causes were falls (43% [median age, 60.5 years]), which were more common in Australian, European and American units (p < .001). They were followed by road traffic accidents (35% [median age, 29.5 years]). Assaults (15% [median age, 31.5 years]) were statistically associated with alcohol and/or drug abuse (p < .001). Of all patients, 39% underwent open reduction and internal fixation, 36% did not receive surgical treatment, and 25% underwent closed reduction. CONCLUSION: Falls were the main cause of maxillofacial injury in the female population in countries with ageing populations, while road traffic accidents were the main cause in African and some Asian centres, especially in patients ≤65 years. Assaults remain a significant cause of trauma, primarily in patients aged 19-64 years, and they are related to alcohol use.

Characteristics and age-related injury patterns of maxillofacial fractures in children and adolescents: A multicentric and prospective study.

BACKGROUND/AIMS: Paediatric maxillofacial trauma accounts for 15% of all maxillofacial trauma but remains a leading cause of mortality. The aim of this prospective, multicentric epidemiological study was to analyse the characteristics of maxillofacial fractures in paediatric patients managed in 14 maxillofacial surgery departments on five continents over a 1-year period. METHODS: The following data were collected: age (preschool [0-6 years], school age [7-12 years], and adolescent [13-18 years]), cause and mechanism of the maxillofacial fracture, alcohol and/or drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injuries, day of the maxillofacial trauma, timing and type of treatment, and length of hospitalization. Statistical analyses were performed using SPSS software. RESULTS: Between 30 September 2019 and 4 October 2020, 322 patients (male:female ratio, 2.3:1) aged 0-18 years (median age, 15 years) were hospitalized with maxillofacial trauma. The most frequent causes of the trauma were road traffic accidents (36%; median age, 15 years), followed by falls (24%; median age, 8 years) and sports (21%; median age, 14 years). Alcohol and/or drug abuse was significantly associated with males (p < .001) and older age (p < .001). Overall, 474 fractures were observed (1.47 per capita). The most affected site was the mandibular condyle in children <13 years old and the nose in adolescents. The proportion of patients who underwent open reduction and internal fixation increased with age (p < .001). CONCLUSION: The main cause of paediatric maxillofacial fractures was road traffic accidents, with the highest rates seen in African and Asian centres, and the frequency of such fractures increased with age. Falls showed an inverse association with age and were the leading cause of trauma in children 0-6 years of age. The choice of treatment varies with age, reflecting anatomical and etiological changes towards patterns more similar to those seen in adulthood.

A multicentric prospective analysis of maxillofacial trauma in the elderly population.

BACKGROUND/AIMS: The growth of the global elderly population will lead to an increase in traumatic injuries in this group, including those affecting the maxillofacial area, with a heavier load on health systems. The aim of this multicentric prospective study was to understand and evaluate the incidences, causes and patterns of oral and maxillofacial injuries in patients aged over 60 years admitted to 14 maxillofacial surgical departments around the world. METHODS: The following data were collected: gender, cause and mechanism of maxillofacial fracture, alcohol and drug abuse at the time of trauma, fracture site, Facial Injury Severity Scale score, associated injury, day of trauma, timing and type of treatment and length of hospitalization. Statistical analyses were performed using non-parametric and association tests, as well as linear regression. RESULTS: Between 30 September 2019 and 4 October 2020, 348 out of 2387 patients (14.6%), 197 men and 151 women (ratio 1.3:1; mean age 72.7 years), were hospitalized. The main causes of the maxillofacial fractures were falls (66.4%), followed by road traffic accidents (21.5%) and assaults (5.2%). Of the 472 maxillofacial fractures, 69.7% were in the middle third of the face, 28% in the lower third and 2.3% in the upper third. Patients with middle third fractures were on average 4.2 years older than patients with lower third fractures (95% CI 1.2-7.2). Statistical analysis showed that women were more involved in fall-related trauma compared with males (p < .001). It was also shown that road traffic accidents cause more fractures in the lower third (p < .001) and in the middle third-lower third complex compared with upper third (p < .001). CONCLUSIONS: Maxillofacial fractures in the elderly were more frequent in European and Australian centres and affected men slightly more than women. Falls were the leading cause of fractures, especially among women. The middle third of the face was most often affected, and conservative treatment was the most common choice for the management of such patients.

Management of maxillofacial trauma in the elderly: A European multicenter study.

BACKGROUND/AIMS: Management of maxillofacial trauma in the geriatric population poses a great challenge due to anatomical variations and medical comorbidities. The aim of this study was to analyze the management variables, timing, and outcomes of facial fractures in elderly patients (aged 70 years or more) at several European departments of oral and maxillofacial surgery. MATERIALS AND METHODS: This study was based on a systematic computer-assisted database that allowed the recording of data from all geriatric patients with facial fractures from the involved maxillofacial surgical units across Europe between 2013 and 2017. RESULTS: A total of 1334 patients were included in the study: 665 patients underwent closed or open surgical treatment. A significant association (P < .005) was found between the presence of concomitant injuries and a prolonged time between hospital admission and treatment. The absence of indications to treatment was associated with comorbidities and an older age (P < .000005). CONCLUSIONS: Elderly patients require specific attention and multidisciplinary collaboration in the diagnosis and sequencing of trauma treatment. A prudent attitude may be kept in selected cases, especially when severe comorbidities are associated and function is not impaired.

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.

Surgical management of unilateral body fractures of the edentulous atrophic mandible.

INTRODUCTION: Management of body fractures in patients with edentulous atrophic mandibles represents a challenging task due to patient's age, medical comorbidities, poor bone quality, and vascularity, as well as reduced contact area between the fracture ends. The aim of the study was to assess the demographic and clinical variables, the surgical technique, and outcomes of unilateral body fractures of the edentulous atrophic mandible managed at several European departments of oral and maxillofacial surgery. METHODS: This study is based on a systematic computer-assisted database that allowed the recording of data of all patients with fractures of the atrophic edentulous mandible from the involved maxillofacial surgical units across Europe between 2008 and 2017. The following data were recorded for each patient: gender, age, comorbidities, etiology, synchronous body injuries, degree of atrophy of the mandible according to Luhr classification, type of surgical approach and fixation, length of hospitalization, and presence and type of complications. RESULTS: A total of 43 patients were included in the study: 17 patients' mandibles were classified as class I according to Luhr, 15 as class II, and 11 as class III. All patients underwent open reduction and internal fixation by extraoral approach in 25 patients, intraoral in 15 patients, and mixed in 3 patients. A single 2.0 miniplate was used in 16 patients, followed by a single 2.4 reconstruction plate in 13 patients, by two 2.0 miniplates, and three 2.0 miniplates. Outcome was considered to be satisfying in 30 patients, with no complications. Complications were observed in 13 cases. CONCLUSIONS: Treatment of unilateral body fractures of the edentulous mandible must still be based on the type of fracture, degree of atrophy, experience of the surgeon, and patients' preference. An adequate stability can be obtained by different plating techniques that have to be appropriately tailored to every single specific patient.

The epidemiology of edentulous atrophic mandibular fractures in Europe.

INTRODUCTION: The objective of the present study was to assess the demographic variables, causes, and patterns of edentulous atrophic fractures of the mandible managed at several European departments of oral and maxillofacial surgery. The results of this multicenter collaboration over a 10-year period are presented. METHODS: The data of all patients with fractures of the atrophic edentulous mandible from the involved maxillofacial surgical units across Europe between January 1, 2008, and December 31, 2017 were recorded: gender; age; voluptuary habits; comorbidities; etiology; fracture sites; synchronous body injuries; atrophy of the mandible according to Luhr classification; eventual type of treatment; timing of the eventual surgery; length of hospital stay. RESULTS: A total of 197 patients (86 male and 111 female patients) with 285 mandibular fractures were included in the study. Mean age of the study population was 75 years. Statistically significant associations were found between Luhr classes I - II and condylar fractures on one hand (p < .0005), and between Luhr class III and body and parasymphyseal fractures on the other hand (p < .05). Finally, 135 patients underwent open reduction and internal fixation, 56 patients did not undergo any intervention, and 6 patients underwent closed reduction. No statistically significant association was observed between treatment, timing of treatment, comorbidities, and concomitant injuries. CONCLUSIONS: The management of edentulous atrophic mandibular fractures remains challenging. Treatment decisions should continue to be based on the clinician's previous experience and on the degree of bone resorption in edentulous mandible in relation to fracture subsites.

Análisis de la tasa de cesáreas en el Hospital Universitario Cruces (Vizcaya) mediante el empleo de la clasificación de Robson / Use of the Robson 10-group classification to assess cesarean section rates in Cruces Hospital (Vizcaya)

OBJETIVO: valorar la frecuencia de las cesáreas realizadas en nuestro hospital empleando la clasificación estandarizada de Robson e identificar qué indicaciones son las que más contribuyen a la tasa global de cesáreas en nuestro centro. MATERIAL Y MÉTODOS: estudio retrospectivo, observacional sobre el total de cesáreas realizadas en el Hospital Universitario Cruces en un periodo de tres años (2015-2017). Para la inclusión de las gestantes en algunos de los 10 grupos de Robson hemos tenido en cuenta la paridad, edad gestacional, inicio del parto, presentación fetal y el número de fetos. RESULTADOS: durante este tiempo se han atendido un total de 15.112 partos; de los que 1.935 fueron cesárea (12,80%). El grupo que mayor incidencia tiene sobre el total de cesáreas realizadas es el grupo 2 (nulíparas, gestación única, presentación cefálica, ≥ 37 semanas, trabajo de parto inducido o cesárea antes del inicio del trabajo de parto) con una tasa del 30,64%, seguido del grupo 1 (nulíparas, gestación única, presentación cefálica, ≥ 37 semanas, trabajo de parto espontáneo) con un 19,22%. Al margen del grupo 9 (que incluye las cesáreas en presentaciones transversas), los grupos con un mayor porcentaje de cesáreas son el 6 (nulíparas, gestación única, presentación podálica) y 7 (multípara, gestación única, presentación podálica, incluidas las gestantes con cesárea anterior) con un 56,83% y 54,54% respectivamente. CONCLUSIONES: la clasificación de Robson es una buena herramienta para auditar clínicamente la tasa de cesáreas. Es fácil de implementar y permite evaluar el impacto del cambio en el manejo para cambiar dicha tasa. En nuestro centro, la protocolización adecuada de la atención a las presentaciones podálicas, gestaciones múltiples y cesáreas anteriores representa el mayor reto

OBJECTIVE: To apply the Robson 10-group classification system to identify which indications are the ones that contribute most to the cesarean section rate in our hospital. MATERIAL AND METHODS: A historical cohort study was performed on women who delivered in a 3-year period (2015-2017) at the Cruces University Hospital. Five parameters (parity including previous cesarean, gestational age, labor onset, fetal presentation, and plurality), identifiable on presentation for delivery, were used to classify all women included into 1 of 10 groups. The Robson distribution, cesarean rate, and contribution of each Robson group were analyzed, and the distribution of other outcomes was calculated for each Robson group. RESULTS: Of 15,112 deliveries, 1,935 (12.80%) were cesarean sections. Robson groups 1 (30.65%) and 3 (29.91%) (spontaneous term births) were the largest groups. Robson group 2 (single cephalic nulliparous women full-term, induced labor or cesarean section antepartum) and group 1 (single cephalic nulliparous women full-term in spontaneous labor) were the major contributors to the overall cesarean rate at 30.64% and 19.22% respectively. Besides group 9 (transverse lie), groups with higher cesarean rates are 6 (single breech, nulliparous) and 7 (single breech, multiparous, including previous cesarean section), with 56.83% and 54.54% respectively. CONCLUSIONS: The Robson classification is a good tool to clinical audit cesarean section rates. Is easy to implement and interpret and allows to evaluate the impact of changes in management that may alter these rates. In our hospital breech presentations, multiple pregnancy and previous cesarean section are the main challenges

Etiología y niveles de resistencia de los uropatógenos más frecuentes en infecciones urinarias de la comunidad / Etiology of community-acquired urinary infections and antimicrobial resistance of the more usual pathogen

Estudio de la etiología de las infecciones urinarias de vías bajas de adquisición comunitaria y de la resistencia de los uropatógenos más frecuentes a los antimicrobianos de primera línea. Entre febrero y junio de 2006, en 15 laboratorios españoles se obtuvieron 3 109 uropatógenos. Escherichia coli fue el más frecuente (70.8%), seguido de Klebsiella spp. (6.8%), Proteus spp. (6.6%) y Enterococcus spp. (5.5%). La resistencia de E.coli fue del 1.7% para fosfomicina, 3.8% para nitrofurantoína, 6.9% para cefixima, 8.1% ante amoxicilina-clavulánico, 8.9% con cefuroxima, y 23.9% para ciprofloxacina. Produjeron betalactamasas de espectro extendido (BLEE) el 5.2% de E. coli, 3.3% de E.cloacae, 2.4% de Klebsiella spp., 2.2% de P. aeruginosa y 1% de Proteus mirabilis. Las resistencias de E. coli a ciprofloxacina fueron inferiores en menores de 40 años (6.7% frente al 33.9% en > 60, p < 0.001), y en algunas áreas geográficas (12.5% frente a 37.3%). El 79.1% de E. coli BLEE se aislaron en mayores de 60 años frente al 7% en < 40, y presentaban variaciones geográficas importantes (18.4% frente a 0.8%). El 68.6% de E. coli BLEE fue resistente a cotrimoxazol y 72.2% aciprofloxacina, frente al 10.6% a nitrofurantoína y 1.9%a fosfomicina. Las tasas de resistencia y de resistencias cruzadas halladas en este estudio representan un grave problema que obliga a revaluar el tratamiento empírico de las infecciones urinarias de las vías bajas.

A multi-center study assessing the etiology of community acquiredlower urinary tract infections and the antimicrobial resistance patterns of the more commonuro-phatogens was undertaken. Between February and June 2006, 3 109 isolates were collected and analyzedin 15 clinical microbiology laboratories. Escherichia coliwas the most frequent isolate (70.8%), followed by theKlebsiella spp. (6.8%) Proteus spp. (6.6%), and by Enterococcus spp. (5.5%). E. coli resistance rate tofosfomycin was 1.7%, to nitrofurantoin, 3.8%, tocefexime 6.9%, to amoxicilin-clavulanic 8.1%, tocefuroxime 8.9%, and to ciprofloxacin 23.9%. It is alsoremarkable that the 5.2% of E. coli, 3.3% E. cloacae,2.4% Klebsiella spp., 2.2% P. aeruginosa and 1% Proteusmirabilis produced extended-spectrum beta-lactamases(ESBL). E. coli resistance rate to ciprofloxacin was lowerin people younger than 40 years (6.7% vs. 33.9% in >60, p < 0.001), and in some geographic regions (12.5%vs. 37.3%). E. coli producing ESBL were recovered inpeople older than 60 years (79.1% vs. 7% in youngerthan 40), and presented important geographic variations(18.4% vs. 0.8%). E. coli producing ESBL were 68.6%resistant to cotrimoxazol, 72.2% to ciprofloxacin vs.10.6% to nitrofurantoin and 1.9% to fosfomycin. Theincreasing rates of resistance and cross-resistancedescribed in this study points out a real problem thatstrengthens the need of new evaluations of the empiric treatment of lower urinary tract infections.
