Trauma-induced complete pacemaker lead fracture 8 months prior to hospitalization: A case report

Trauma-induced complete lead fracture is a rare complication of pacemaker implantation. Only a few cases have been previously reported. Common treatment included replacement of pacemaker and/or extraction of fractured lead. In this report, however, we describe this unique case of complete traumatic pacemaker lead fracture. The patient had her right-ventricular lead fractured after a bicycle accident and had lived with the fractured lead for 8 months prior to her hospitalization. After examinations, she was treated with a relatively conservative strategy. The pacemaker and fractured lead were left for further observation and follow-up.

Exposure to Descriptions of Traumatic Events Narrows One’s Concept of Trauma

The word 'trauma' was originally used by psychiatrists to describe horrific events such as rape and torture that characteristically provoke extreme emotional distress. Both colloquially and clinically, the concept of psychological trauma has broadened considerably. Although many clinical scientists have expressed concern about the broadening of the concept of trauma, it remains unclear how and why this concept expansion occurs. We present two experiments in which US adults (N = 276, 267) sequentially classified descriptions of events (e.g., "broke a leg in a bicycle accident") as either 'trauma' or 'not trauma'. In the first experiment, we manipulated the frequency of serious and nonserious events. In the second experiment, we manipulated the total range of events (i.e., participants viewed only nonserious or only serious events). Together, the experiments suggest that participants' frame of reference for events (i.e., the perceived range of event seriousness) plays a relatively more important role.

Survival of a Maxillary Incisor in an Adolescent Male 16 Years after Its Delayed Replantation

Introduction: Recreational and sport activities, traffic accidents and human behaviour represent the main causes of trauma in young people. Case presentation: This report describes a case of a 15.2-year-old male who suffered uncomplicated crown fracture and avulsion of tooth 11 and uncomplicated crown fracture of tooth 21 due to a bicycle accident. Tooth 11 was dry stored and it was replanted 18 h after the trauma. The root was planed to remove the necrotic periodontal tissue, the pulp was extirpated before replantation and a flexible splint was applied to tooth 13 to tooth 23 for 3 weeks. A replacement root resorption of replanted tooth was suspected at the 3-month radiographic control and suffered a dramatic increase later; minimal infraocclusion, about 1 mm, was observed due to its ankylosis. Sixteen years after the trauma the patient was scheduled for an orthodontic and implanto-prosthetic rehabilitation. Conclusion: Delayed replantation usually has a long-term poor prognosis, so it is very important to promote awareness regarding emergency management modalities in dental traumatology especially among parents, school teachers, and coaches that are usually present at the site of the accident.

Investigating Roundabout Properties and Bicycle Accident Occurrence at Swiss Roundabouts: A Logistic Regression Approach

The positive effects of active mobility on mental and physical health as well as on air quality are widely acknowledged. Increasing the share of active travel is therefore an aim in many countries. Providing bicycle-safe infrastructure is one way to promote cycling. Roundabouts are a common traffic infrastructure and are supposed to facilitate safe and smooth traffic flow. However, data on road traffic accidents indicate an over-proportional involvement of cyclists in accidents at roundabouts. In the present study, the influence of roundabout geometry and traffic flow on bicycle accident occurrence was investigated using a logistic regression approach on twelve parameters of N = 294 mostly small- and mini-sized single-lane roundabouts in the Canton of Berne, Switzerland. Average weekday motorized traffic was identified as a major factor in explaining bicycle accident occurrence at roundabouts. Further, the radius of the central island, the location of the roundabout (in town vs. out of town) and the number of legs were significantly related to bicycle accident occurrence. While these results are in general agreement with findings from similar studies, the findings regarding the central island’s radius and the number of legs underpin the need for roundabout type-specific studies: Some parameters may not prove relevant in intermediate- to large-sized roundabouts, but become critical in small or mini roundabouts, which are common in Switzerland and numerous in the present sample.

The bicycle accident in Brazil: an integrative review / Os acidentes de bicicleta no Brasil: uma revisão integrativa

Objetivo: analisar a produção científica acerca dos acidentes de bicicleta produzidos no Brasil. Método: revisão integrativa com propósito de responder à questão “Qual o conhecimento científico já produzido no Brasil sobre acidentes de bicicleta?” Os dados foram coletados no período de junho a agosto de 2015 nas bases MEDLINE e LILACS, artigos em português e inglês, utilizando-se os descritores: “ciclismo”, “acidentes de trânsito”, “Brasil”, “saúde pública”, “epidemiologia” e “mortalidade”. Resultados: Foram analisados 15 artigos agrupados em duas categorias: perfil epidemiológico das lesões e perfil epidemiológico dos acidentes. Conclusões: Nota-se ser necessário ampliar os estudos referentes a este tema, nos diferentes estados brasileiros, uma vez que os acidentes de bicicleta passam a ter papel importante no campo da Saúde, em especial para a Enfermagem, que irá planejar e implementar cuidados com as vítimas.
