Percutaneous cerclage wiring for the surgical treatment of displaced patella fractures
The patella plays an important role in the knee joint extension, and a patella fracture requires surgical treatment when it is accompanied by displacement of bone fragments and a joint surface gap. In patella fractures, there is disruption of the soft tissue structures that support the knee extension mechanism. We use a method of percutaneous cerclage wiring to fix the patella and include the peripatellar soft tissues in five patients. All cases were closed fractures, and the AO classification was type A in 1 and type C in 4. At a mean follow-up of 11.2 months, union was achieved in four cases with failure in one inferior pole fracture avulsion. There was no extensor lag noted in any patient, with mean flexion at 141° (120–160). As this percutaneous cerclage wiring method includes soft tissue approximation in the wiring, it may be especially suitable for comminuted fractures for which classic tension band wiring techniques cannot be used. We employed this procedure to atraumatically manipulate peripatellar soft tissues together with the fracture fragments in order to obtain optimal restoration of continuity of the extensor mechanism

Dental hygienists’ perceptions of professionalism are multidimensional and context-dependent: a qualitative study in Japan
Abstract Background Due to the declining birth rate and aging of Japanese society, the roles and responsibilities of dental hygienists are continuously expanding. Medical professionalism needs to be pursued continuously throughout one’s career in order to improve dental care and treatment. Although conceptualising professionalism is essential to the education of health professionals, professionalism in the field of dental hygiene has not been defined or adequately examined in Japan. The purposes of this study are to investigate dental hygienists’ perceptions of the constituent elements of professionalism and the factors affecting their perceptions. Methods Semi-structured interviews were conducted with 18 dental hygienists in Japan. Drawing on the conceptualisation of professionalism in medicine described by Van de Camp et al., the transcribed data were thematically analysed. Results The dental hygienists in this study perceived 70 constituent elements that were categorised into eight core competencies related to professionalism. These competencies were further classified into three main themes: intrapersonal, interpersonal, and public professionalism. There were three sociohistorical factors that affected their perceptions of the constituent elements, namely academic background (university or technical school), the contexts of any previously provided dental care (university hospital or dental clinic), and their social interactions with their colleagues during their engagement in dental practice (dental team or interprofessional team). Moreover, according to their sociohistorical backgrounds, the dental hygienists saw themselves variously as scholars (university graduates), facilitators (university hospital), skillful artisans (dental clinic), or collaborators (interprofessional team). Conclusions Dental hygienists’ perceptions of professionalism are multidimensional and context-dependent, so culture- and professional-specific elements need to be included in educational curricula and continuing professional development programmes. In particular, the conceptualisation of professionalism in the field of dental hygiene as described in this study can be a springboard for enhancing undergraduate education and clinical training
Dental trainees reflect more critically on negative experiences: portfolio analysis using a pragmatic approach and a rubric in Japan
Abstract Background Dental trainees have various clinical experiences during their internships and they grow by experiencing success and failure. When looking back on an event, it is not apparent which experiences result in more critical reflection. Therefore, we qualitatively analyzed the portfolios of dental trainees using Significant Event Analysis to investigate their depth of reflection. Methods We asked all Hiroshima University Hospital dental trainees who completed a 1-year training program between 2010 and 2016 to describe their most memorable event from the past year. We coded the text using a qualitative analysis method. Then, we classified the responses as positive or negative events. We evaluated the depth of reflection following a pragmatic approach to categorizing reflective material (Sandars method) and a reflective ability rubric and user guide (O’Sullivan method) and compared these results. The evaluation was performed separately by two researchers and a good rate of agreement was confirmed by the weighted kappa statistic. Comparison of the depth of reflection was performed by the Mann-Whitney U test. Results The assessments of the positive event group and negative event group were compared with the respective evaluation criteria of the Sandars and O’Sullivan methods, and reflection was found to be deeper in the negative event group. The Mann-Whitney U test revealed a significant difference (p < 0.05) in the median values of the two groups for both methods. Conclusions Both positive and negative experiences are important for dental practitioners to grow, but negative experiences are associated with critical reflections. In promoting the growth of training dentists, it is considered important to encourage deep reflections on positive experiences that are likely to be shallow

Head and neck cancer patients show poor oral health as compared to those with other types of cancer
Abstract Purpose Several studies have found associations between periodontitis and various types of cancer. Since the site of head and neck cancer (HNC) has contiguity or proximity to the oral cavity, it may be particularly influenced by oral inflammation. This study aimed to determine whether HNC patients have poor oral health as compared to those with other types of cancer. Methods This study retrospectively examined oral environmental factors including periodontal inflamed surface area (PISA), a new periodontal inflammatory parameter. A total of 1030 cancer patients were divided into the HNC (n = 142) and other cancer (n = 888) groups. Furthermore, the HNC group was divided into high (n = 71) and low (n = 71) PISA subgroups, and independent risk factors affecting a high PISA value were investigated. Results Multivariate logistic regression analysis showed that number of missing teeth (odds ratio 1.72, 95% CI 1.15–2.56, P < 0.01), PISA (odds ratio 1.06, 95% CI 1.03–1.06, P < 0.05), and oral bacterial count (odds ratio 1.02, 95% CI 1.01–1.03, P < 0.01) were independent factors related to HNC. In addition, multivariate logistic regression analysis indicated that current smoker (odds ratio 7.51, 95% CI 1.63–34.71, P < 0.01) and presence of untreated dental caries (odds ratio 3.33, 95% CI 1.23–9.00, P < 0.05) were independent risk factors affecting high PISA values in HNC patients. Conclusion HNC patients have higher levels of gingival inflammation and poor oral health as compared to patients with other types of cancer, indicating that prompt oral assessment and an effective oral hygiene management plan are needed at the time of HNC diagnosis
