'Making every contact count' with patients with musculoskeletal conditions: a qualitative exploration of acceptability to physiotherapists.

AIM: To qualitatively explore physiotherapists' experiences and acceptability of implementing 'Making Every Contact Count Healthy Conversation Skills' (MECC HCS) in routine practice with patients with musculoskeletal (MSK) conditions. METHODS: This article reports the second phase of a mixed method, sequential explanatory study. Physiotherapists trained in and delivering MECC HCS in their practice were invited to take part in semi-structured interviews. We hoped to develop a rich, in-depth understanding of their use and perceptions of the brief intervention and to contextualise findings from the first phase of the study. Qualitative data were analysed using Reflexive Thematic Analysis. RESULTS: Physiotherapists valued MECC HCS as being integral to their practice, promoting a person-centred approach to supporting behaviour change and enhancing self-management in patients with MSK conditions and pain. It was believed that this brief intervention could reduce workload pressure for physiotherapists and have significant wider benefits for health services. Time limitations associated with appointments did, however, pose as a challenge to MECC HCS delivery, and it was felt that more organisational-level support was needed to sustain it. CONCLUSIONS: These findings support our quantitative data, collected in the first phase of this study. MECC HCS is a highly acceptable brief intervention that can be delivered in physiotherapy care to support behaviour change in patients with MSK conditions. Future roll-out may be optimised within organisations by providing regular refresher training and adopting a MECC champion.

Assessing coastline recession for adaptation planning: sea level rise versus storm erosion.

The Sixth Assessment report (AR6) of the Intergovernmental Panel on Climate Change (IPCC) states with high confidence that most sandy coasts around the world will experience an increase in coastal erosion over the twenty-first century. An increase in long term coastal erosion (coastline recession) along sandy coasts can translate into massive socio-economic impacts, unless appropriate adaptation measures are implemented in the next few decades. To adequately inform adaptation measures, it is necessary to have a good understanding of the relative importance of the physical processes driving coastline recession, as well as of linkages between consideration (or not) of certain processes and the level of risk tolerance; understandings that are hitherto lacking. Here, we apply the multi-scale Probabilistic Coastline Recession (PCR) model to two end-member sandy coastal types (swell dominated and storm dominated), to investigate where and when coastline recession projections are dominated by the differential contributions from Sea Level Rise (SLR) and storm erosion. Results show that SLR substantially increases the projected end-century recession at both types of coasts and that projected changes in the wave climate have only a marginal impact. An analysis of the Process Dominance Ratio (PDR), introduced here, shows that the dominance of storm erosion over SLR (and vice versa) on total recession by 2100 depends on both the type of the beach and the risk tolerance levels. For moderately risk-averse decisions (i.e. decisions accounting only for high exceedance probability recessions and hence do not account for very high amounts of potential recession-for example, the placement of temporary summer beach cabins), additional erosion due to SLR can be considered as the dominant driver of end-century recession at both types of beaches. However, for more risk-averse decisions that would typically account for higher potential recession (i.e. lower exceedance probability recessions), such as the placement of coastal infrastructure, multi-storey apartment buildings etc., storm erosion becomes the dominant process. The results of this study provide new insights on which physical processes need to be considered when and where in terms of numerical modelling efforts needed for supporting different management decisions, potentially enabling more streamlined and comprehensive assessments of the efficacy of coastal adaptation measures.

'I can feel myself coming out of the rut': a brief intervention for supporting behaviour change is acceptable to patients with chronic musculoskeletal conditions.

AIM: To a) understand the perceptions and experiences of patients with musculoskeletal (MSK) conditions in relation to their physiotherapy care and their acceptability of 'Making Every Contact Count Healthy Conversation Skills' (MECC HCS) as a brief intervention within this care and, b) explore the mechanisms through which MECC HCS might facilitate behaviour change and enhance self-management in patients with MSK conditions. METHODS: This study adopted an exploratory qualitative design, in which individual, semi-structured interviews with participants were conducted. Eight participants were interviewed. Five had been engaging with physiotherapists trained in and delivering MECC HCS within their routine physiotherapy appointments and three had been engaging with physiotherapists who had not received this training and were instead delivering usual care. MECC HCS is a person-centred approach to behaviour change that aims to empower individuals to take control of their health behaviours by building self-efficacy. The MECC HCS training programme helps healthcare professionals to develop skills in i) using 'open discovery' questions to explore context and allow patients to identify barriers and generate solutions; ii) listening more than giving information/ making suggestions; iii) reflecting on practice and iv) supporting Specific, Measurable, Action-oriented, Realistic, Timed, Evaluated, Reviewed (SMARTER) goal setting. RESULTS: Those who had engaged with MECC HCS trained physiotherapists found their physiotherapy care highly acceptable and felt that their physiotherapist listened to them, tried to understand their context and world, and helped them plan for change. These individuals experienced increases in self-efficacy and motivation for self-managing their MSK conditions. A need for continued support following physiotherapy treatment was, however, emphasised for long-term self-management. CONCLUSIONS: MECC HCS is highly acceptable to patients with MSK conditions and pain and may successfully facilitate health-promoting behaviour change and enhance self-management. Providing opportunities to join support groups following physiotherapy treatment may promote long-term self-management and provide social and emotional benefits for individuals. The positive findings of this small qualitative study warrant further investigation on the differences in experiences and outcomes between patients engaging with MECC HCS physiotherapists and those receiving treatment as usual during routine physiotherapy care.

Predictors of Infection and Benefit of Antibiotics in Gunshot Wounds to the Face.

BACKGROUND: Gunshot wounds (GSWs) to the face are at high risk for infection due the extent of tissue injury and often-observed violation of oral and sinus cavities. Given the ambiguous data on antibiotic benefit in GSW to the face, the purpose of this study is to characterize antibiotic usage, infection details, and risk factors associated with higher infection rates in GSW to face. METHODS: We conducted a retrospective review of patients presenting with GSW to the face from 2009 to 2017. The primary outcome was to identify risk factors associated with infections in patients with facial GSWs. A stepwise multivariate linear regression analysis was performed to determine the impact of specific injury details. RESULTS: Two hundred sixty-nine patients qualified for the study. Demographic information and details of hospital stay are presented in tables. Most patients (88.8%) received admission antibiotics. Facial infections were observed in 36 patients (13.4%). The infected cohort required more antibiotic days (P < 0.001), higher percentage of invasive airway procedures (P = 0.01), longer length of stay (P < 0.001), greater number of surgeries (P < 0.022), and higher readmission rates (P < 0.001). Factors associated with head or neck infections included oral cavity (odds ratio, 1.23; P = 0.04) and sinus involvement (odds ratio, 1.10; P = 0.045). CONCLUSIONS: Bullet trajectories that violated the oral or maxillary sinus cavities were associated with higher head and neck infection rates. Patients without oral cavity or sinus involvement had a lower chance (4.1%) of developing an infection and therefore may have marginal benefit from antibiotics.

Trainee doctors' perceptions of the surgeon stereotype and its impact on professional identification: a qualitative study.

BACKGROUND: The demography of the medical profession is changing as more women join the workforce. Traditional assumptions about the personal qualities required to be a successful surgeon may change as more women join the specialty. While exploring the attitudes and beliefs of doctors in their second 'Foundation' year of post-graduate training (FY2) about their choice of specialty, evidence emerged about how the stereotype of the surgeon influences professional identification and beliefs about person-specialty fit. METHODS: Qualitative telephone interviews with 24 FY2 doctors, 17 women and 7 men, in South-West England. RESULTS: Many participants reported exposure to stereotypes about the personal qualities desirable in a surgeon. Senior doctors and other trainees were the primary source of these stereotypical views. Experience on surgical placements could either reinforce stereotypes or challenge them, the latter particularly where senior surgeons provided positive role models. As more women enter the surgical specialties, they are increasingly challenging the traditional stereotype and sub-culture. CONCLUSION: Gendered stereotypes about surgical roles persist, and for some this can hinder professional identification with the role. Positive role models and mentoring can encourage and support women who are interested a surgical career to identify with the role, but there is a need for a broader debate encompassing job redesign and surgical identities.

How useful is the Making Every Contact Count Healthy Conversation Skills approach for supporting people with musculoskeletal conditions?

Aim: To explore the current use and perceptions of the Wessex model of Making Every Contact Count (MECC), incorporating Healthy Conversation Skills (HCS), focussing specifically on physiotherapists supporting people living with musculoskeletal conditions. Methods: A mixed method, sequential explanatory design was employed. This article reports the first phase of the study, in which an online questionnaire was administered, consisting of items relating to perceived acceptability, appropriateness, feasibility, sustainability, and uptake of MECC HCS. Barriers and facilitators to MECC HCS delivery were additionally explored and mapped to the Theoretical Domains Framework. Results: Seventy-one professionals responded, including 15 physiotherapists supporting people with MSK conditions. Across professional groups, MECC HCS was found to be highly acceptable, appropriate, and feasible. A significant interaction between perceived sustainability of MECC HCS and the location in which professionals worked was observed. Physiotherapists reported using their MECC HCS at least daily; however, there were discrepancies between the number of their patients they believed could benefit from behaviour change intervention, and the number to whom they reported actually delivering MECC HCS. Perceived barriers and facilitators to MECC HCS implementation mapped mostly to 'Environmental Context and Resources' on the Theoretical Domains Framework. Conclusions: The Wessex model of MECC is a promising brief or very brief intervention for physiotherapists supporting individuals with musculoskeletal conditions. Barriers associated with the sustainability of the intervention within organisations must be addressed in order to enhance future implementation. Further rollout of this intervention may be beneficial for meeting the goals of the NHS and Public Health England in prevention of chronic MSK conditions and promotion of musculoskeletal health.

Impact of Opioid-Minimizing Pain Protocols After Burn Injury.

In 2019, we implemented a pill-based, opioid-minimizing pain protocol and protocolized moderate sedation for dressing changes in order to decrease opioid exposure in burn patients. We hypothesized that these interventions would reduce inpatient opioid exposure without increasing acute pain scores. Two groups of consecutive patients admitted to the burn service were compared: Pre-group (from January 1, 2018 to July 31, 2019) and Post-group (from January 1, 2020 to June 30, 2020) from before and after the implementation of the protocols (from August 1, 2019 to December 31, 2019). We abstracted patient demographics and burn injury characteristics from the burn registry. We obtained opioid exposure and pain scale scores from the electronic medical record. The primary outcome was total morphine milligram equivalents (MMEs). Secondary outcomes included MMEs/day, pain domain-specific MMEs, and pain scores. Pain was estimated by creating a normalized pain score (range 0-1), which incorporated three different pain scales (Numeric Rating Scale, Behavioral Pain Scale, and Behavioral Pain Assessment Scale). Groups were compared using Wilcoxon rank-sum and chi-square tests. Treatment effects were estimated using Bayesian generalized linear models. There were no differences in demographics or burn characteristics between the Pre-group (n = 495) and Post-group (n = 174). The Post-group had significantly lower total MMEs (Post-group 110 MMEs [32, 325] vs Pre-group 230 [60, 840], P < .001), MMEs/day (Post-group 33 MMEs/day [15, 54] vs Pre-group 52 [27, 80], P < .001), and domain-specific total MMEs. No difference in average normalized pain scores was seen. Implementation of opioid-minimizing protocols for acute burn pain was associated with a significant reduction in inpatient opioid exposure without an increase in pain scores.

Doctor-patient interactions that exclude patients experiencing homelessness from health services: an ethnographic exploration.

BACKGROUND: People experiencing homelessness have poor health indices and poor access to health care. Their health service utilisation (HSU) is typified by: late illness presentations; poor attendance rates at appointments; low usage of primary care services and outpatient departments; and high utilisation of emergency departments and inpatient services. Why people experiencing homelessness have these particular HSU patterns is poorly understood. AIM: This research sought to explore barriers to health service usage for people experiencing homelessness. DESIGN & SETTING: The authors conducted critical realist ethnography over 13 months in Dublin with people experiencing homelessness at four purposively chosen sites (a food hall, a drop-in centre, an emergency department, and an outreach service for rough sleepers). METHOD: Ethnographic research was supplemented with focus groups of hospital doctors and people experiencing homelessness, and with 50 semi-structured interviews with people experiencing homelessness. The epistemological framework was critical realism. RESULTS: One of the factors identified in the research as contributing to the HSU pattern of people experiencing homelessness was recurrent interactions between health professionals and patients, whereby patients were either excluded or discouraged from attending health services, or self-excluded themselves from services. These interactions were described as 'conversations of exclusion'. Four such conversations were described: 'the benzodiazepine conversation'; 'the mistrustful conversation'; 'the blaming conversation'; and 'the assertive conversation'. CONCLUSION: There are certain recurrent interactions between people experiencing homelessness and doctors that result in the exclusion of people experiencing homelessness from health services.

The Epidemiology and Management of Pediatric Maxillary Fractures.

BACKGROUND: Most literature regarding traumatic Le Fort or maxillary fractures exists in the adult population, with limited information regarding the epidemiology and management of pediatric fractures. The purpose of this study was to evaluate fracture mechanism, surgical management, and associated injuries in pediatric patients with Le Fort fractures. METHODS: A retrospective chart analysis of all pediatric patients age ≤18 years diagnosed with facial fractures at a single level 1 trauma center over a 10-year period (January 2006-December 2015) was performed. Demographics, fracture location, mechanism of injury, and hospital course were abstracted as well as associated injuries and need for operative management. RESULTS: A total of 1274 patients met inclusion criteria. Sixty-nine (5.4%) presented with Le Fort fractures. Factors associated with Le Fort fractures included motor vehicle collisions (P < 0.001), increased age (P < 0.001), and traumatic brain injury (P < 0.04). Patients with Le Fort fractures were more likely to need intensive care unit admission (P < 0.001), surgical management (P < 0.001), transfusions (P < 0.001), secondary fixation surgery (P < 0.001), and have a longer length of stay (P < 0.001). Multivariate showed increased odds for increased age (OR 1.1; 95%CI 1.04-1.17) and concomitant orbit fractures (OR 8.33; 95%CI 4.08-19.34). Decreased odds were associated for all mechanisms of injury other than motor vehicle collisions (Other blunt trauma: OR 0.36; 95%CI 0.2-0.6. Penetrating trauma: OR 0.13; 95%CI 0.01-0.6). CONCLUSION: Maxillary or Le Fort fractures represent a small portion of pediatric facial fractures but require high rates of operative management. The high velocity required to create this fracture type is associated with significant traumatic comorbidities, which can complicate the hospital course.

Low-cost sensors as an alternative for long-term air quality monitoring.

Low-cost air quality sensors are increasingly being used in many applications; however, many of their performance characteristics have not been adequately investigated. This study was conducted over a period of 13 months using low-cost air quality monitors, each comprising two low-cost sensors, which were subjected to a wide range of pollution sources and concentrations, relative humidity and temperature at four locations in Australia and China. The aim of the study was to establish the performance characteristics of the two low-cost sensors (a Plantower PMS1003 for PM2.5 and an Alphasense CO-B4 for carbon monoxide, CO) and the KOALA monitor as a whole under various conditions. Parameters evaluated included the inter-variability between individual monitors, the accuracy of monitors in comparison with the reference instruments, the effect of temperature and RH on the performance of the monitors, the responses of the PM2.5 sensors to different types of aerosols, and the long-term stability of the PM2.5 and CO sensors. The monitors showed high inter-correlations (r > 0.91) for both PM2.5 and CO measurements. The monitor performance varied with location, with moderate to good correlations with reference instruments for PM2.5 (0.44< R2 < 0.91) and CO (0.37< R2 < 0.90). The monitors performed well at relative humidity < 75% and high temperature conditions; however, two monitors in Beijing failed at low temperatures, probably due to electronic board failure. The PM2.5 sensor was less sensitive to marine aerosols and fresh vehicle emissions than to mixed urban background emissions, aged traffic emissions and industrial emissions. The long-term stability of the PM2.5 and CO sensors was good, while CO relative errors were affected by both high and low temperatures. Overall, the KOALA monitors performed well in the environments in which they were operated and provided a valuable contribution to long-term air quality monitoring within the elucidated limitations.

What influences young doctors in their decision-making about general practice as a possible career? A qualitative study.

Background: Recruitment to General Practitioner (GP) training programmes in the United Kingdom is poor. Colleagues' negative comments about general practice could contribute to this.Aim: To investigate what influences Foundation Year 2 (FY2) doctors in their decisions to choose general practice as a career, and how colleagues' comments about GPs might affect those decisions.Design and Setting: A qualitative study in Southwest England.Method: Thematic analysis of interviews with FY2 doctors.Results: Twenty-four doctors participated. They thought that GPs worked hard and had very varied clinical work. The effect on their career choice depended on their personalities. GP placement experiences significantly influenced their career intentions. The loneliness of working in general practice was a key concern. FY2 doctors thought colleagues' criticisms of GPs did not reflect reality and were outdated. 'Banter' had little effect on career choices.Conclusion: Person-specialty fit and FY2 doctors' experiences of GP work have a significant effect on career choices. Loneliness in their GP work placements is a particular problem that should be addressed. While colleagues' derogatory comments about GPs may affect medical students' views on their career choices, they appear to have little effect on the career decision-making of qualified doctors.Abbreviations: CMT: Core Medical Training; FY2: Foundation Year 2; GP: general practitioner; NHS: National Health Service; UK: United Kingdom.

Making sense of street chaos: an ethnographic exploration of homeless people's health service utilization.

BACKGROUND: Homeless people have poor health and mortality indices. Despite this they make poor usage of health services. This study sought to understand why they use health services differently from the domiciled population. METHODS: Ethnographic observations were conducted at several homeless services, in Dublin. This was supplemented with 47 semi-structured interviews with homeless people and two focus groups of homeless people and hospital doctors. A critical-realist approach was adopted for interpretation of the data. RESULTS: Homeless people tended to present late in their illness; default early from treatment; have low usage of primary-care, preventative and outpatient services; have high usage of Emergency and Inpatient services; and poor compliance with medication. They tended to avoid psychiatric services. A number of external barriers were identified. These were classified as physical (distance) administrative (application process for medical care; appointments; queues; the management of addiction in hospital; rules of service; and information providing processes); and attitudinal (stigma; differing attitudes as to appropriate use of services. A new form of barrier, Conversations of Exclusion was identified and described. Internalised barriers were identified which were in nature, either cognitive (fatalistic, denial, deferral to future, presumption of poor treatment or discrimination, self blame and survival cognitions) or emotional (fear; embarrassment, hopelessness and poor self-esteem). Generative mechanisms for these factors were identified which either affected participants prior to homelessness (marginalization causing hopelessness, familial dysfunction, substance misuse, fear of authority, illiteracy; mental health; and poor English) or after becoming homeless (homelessness; ubiquity of premature death; substance misuse; prioritization of survival over health; threat of violence; chaotic nature of homelessness; negative experiences of authority; and stigma. CONCLUSIONS: An explanatory critical realist model integrating the identified generative mechanisms, external and internalised barriers was developed to explain why the Health service Utilization of homeless people differs from the domiciled populations. This new model has implications for health service policy makers and providers in how they design and deliver accessible health services to homeless people.

Factors Associated With Surgical Management for Pediatric Facial Fractures at a Level One Trauma Center.

Pediatric facial fractures present and are managed differently than the adult population. This study describes the pattern and mechanism of facial fractures in children and identifies factors associated with need for surgical management. An IRB-approved retrospective chart analysis of all pediatric patients age ≤ 18 years diagnosed with facial fractures at our level 1 trauma center over a 10-year period (January 2006-December 2015) was performed. Demographics, fracture location, mechanism of injury, concomitant head and neck injuries, and surgical management were reviewed. Statistical analysis was then performed comparing surgical and nonsurgical cohorts using univariate and multivariate analyses. One thousand two hundred seventy-four patients were diagnosed with facial fractures. Five hundred seventeen (40.6%) underwent surgical management. Two thousand one hundred seventy-two total facial fractures were recorded. Orbit fractures (29%) were the most commonly recorded, observed in 49% of patients presenting. Increased age was associated with increased odds of surgical management (OR 1.13; 95% CI 1.09-1.16). Mandible (OR 9.28; 95% CI 6.88-12.51) and Le Fort fractures (OR 19.73; 95% CI 9.78-39.77) had increased odds of surgical management. Patients with traumatic brain injury had reduced odds (OR 0.54; 95% CI 0.35-0.83) of surgical management for their facial fractures. Older pediatric patients may be more likely to require surgical management of their facial fractures, especially those with mandible or Le Fort fractures. Patients with traumatic brain injury are likely to sustain life threatening injuries, deferring repair of their facial fractures. Patient education and counseling, as well as predictive models, can be improved to reflect these data.

The Trends of Pediatric Facial Fractures Due to Violence in a Level One Trauma Population.

INTRODUCTION: Pediatric facial fractures due to intentionally violent mechanisms represent a unique subset of facial fractures. The objective of our research is to identify how violence affects patterns of facial fractures and their management in pediatric patients. METHODS: An IRB approved, retrospective study of our institution's pediatric patients ≤18 years of age who presented with ≥1 facial fracture due to violence from January 2006 to December 2015 was performed. Violence was defined as trauma intended to hurt another or self. Demographics, fractures, mechanism, concomitant injuries, and management were analyzed. RESULTS: The 1274 patients were diagnosed with facial fractures, with 235 of these due to violence (18%). These patients of violence (POV) had 332 fractures, with an average fracture per patient of 1.4 ±â€Š.0.8. The majority (86%) were male, Non-Hispanic African American (35%), and the average age was 15.9 ±â€Š2.8 years. The most common fracture was the mandible (50% of patients) and most common mechanism was assault (76%). The POV were older, male, and of minority race/ethnic groups when compared to patients of non-violence (PONV) (P <0.01). The POV presented with fewer concomitant injuries, were less likely to be admitted to the intensive care unit, and more often surgically managed when compared to the PONV (P <0.01). CONCLUSION: This study represents the largest US, single institution, Level 1 trauma center study of pediatric facial fractures. Pediatric patients with facial fractures due to a violent mechanism represent a distinct category of trauma patients with a unique profile of injuries.

How does 'banter' influence trainee doctors' choice of career? A qualitative study.

BACKGROUND: Negative comments from senior colleagues about specialties, such as general practice and psychiatry, are known to influence trainees' career choice, but little is known about the extent of this influence or the mechanism by which it works. There have been calls to ban these disparaging comments, also known as 'banter'. This study explored how recently qualified doctors make sense of banter in the context of other experiences and information. METHODS: Semi-structured telephone interviews were conducted with 24 trainee doctors in their second postgraduate year in South West England. Thematic Analysis was used to code the data and organise them into themes. RESULTS: Trainees are commonly exposed to banter about the merits of different specialties and those who work in them, but these messages are not received uncritically and are not perceived to be decisive in determining career choice. The views of senior doctors are assimilated with other experiences and information, as trainees strive to assess their 'fit' with a specialty. While banter is seen as positioning specialties in a status hierarchy, other factors such as work-life balance and feeling 'at home' in a specialty are often believed to be more significant factors in career choice. We posited two theories of banter; the 'propaganda model' and the 'person-specialty fit model,' and found the latter to provide a better understanding of how banter informs career choice. CONCLUSIONS: Banter often comprises stereotypes and caricatures, but despite its biases and distortions, it may still aid career choice. The challenge is not to ban banter, but to provide more accurate and reliable knowledge and experiences of what working life is like in different specialties.

Terrorism and post-traumatic stress disorder: a historical review.

Terror is a psychological state. Historically, most studies of terrorism focused on its societal purpose and structural consequences rather than mental health effects. That emphasis began to change shortly before the Sept 11, 2001, terrorist attacks. A vast expansion of research into post-traumatic stress disorder accompanied revisions to the classification of mental health disorders. The effect of terrorist incidents on those people now deemed vulnerable, both directly and indirectly, was actively sought. However, a review of more than 400 research articles (mostly published after Sept 11) on the association between terrorism and mental health reached the largely overlooked conclusion that terrorism is not terrorising-at least not in a way that causes a greater than expected frequency of post-traumatic stress disorder than other traumatic events. This conclusion is surprising given the emphasis on the psychological effects of terrorism in political discourse, media commentary, contemporary culture, and academic inquiry. Authorities might prefer to encourage an interpretation of terrorist incidents that highlights fortitude and courage rather than psychological vulnerability.

Outcomes research: Mandibular fractures in the diabetic population.

OBJECTIVE: The study aimed to examine the management and outcomes of mandibular fractures in patients with diabetes mellitus by examining the injury modalities, treatment methods, and complications. METHODS: The study conducted was a retrospective case review of patients admitted to Memorial Hermann Hospital from 2007 to 2011 with diagnoses of diabetes mellitus and mandibular fracture. The electronic medical records were reviewed for patient demographics, injury data, surgery methodology, treatment variables, and complications. RESULTS: Out of the 34 diabetic patients, the average age was 52 with the majority of the fractures being the result of falls, 12 (35.3%). Of the 63 total fractures, 24 (38.1%) fractures were repaired through closed reduction and 39 (61.9%) fractures required open reduction with internal fixation. 17 (50.0%) patients had at least one complication following mandibular fracture repair. The most common complications in this sample population included nerve injury, 7 (20.6%), infection, 7 (20.6%), wound dehiscence with or without hardware exposure, 6 (17.7%), and malocclusion, 5 (14.7%). CONCLUSION: When compared to the limited published data our findings imply that diabetic patients with mandibular fractures present as an older population than commonly seen with mandibular fractures and suggest a higher overall rate of complications.

Changes in atmospheric concentrations of polycyclic aromatic hydrocarbons and polychlorinated biphenyls between the 1990s and 2010s in an Australian city and the role of bushfires as a source.

Over recent decades, efforts have been made to reduce human exposure to atmospheric pollutants including polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) through emission control and abatement. Along with the potential changes in their concentrations resulting from these efforts, profiles of emission sources may have also changed over such extended timeframes. However relevant data are quite limited in the Southern Hemisphere. We revisited two sampling sites in an Australian city, where the concentration data in 1994/5 for atmospheric PAHs and PCBs were available. Monthly air samples from July 2013 to June 2014 at the two sites were collected and analysed for these compounds, using similar protocols to the original study. A prominent seasonal pattern was observed for PAHs with elevated concentrations in cooler months whereas PCB levels showed little seasonal variation. Compared to two decades ago, atmospheric concentrations of ∑13 PAHs (gaseous + particle-associated) in this city have decreased by approximately one order of magnitude and the apparent halving time (t1/2) was estimated as 6.2 ± 0.56 years. ∑6iPCBs concentrations (median value; gaseous + particle-associated) have decreased by 80% with an estimated t1/2 of 11 ± 2.9 years. These trends and values are similar to those reported for comparable sites in the Northern Hemisphere. To characterise emission source profiles, samples were also collected from a bushfire event and within a vehicular tunnel. Emissions from bushfires are suggested to be an important contributor to the current atmospheric concentrations of PAHs in this city. This contribution is more important in cooler months, i.e. June, July and August, and its importance may have increased over the last two decades.
