Clinical implications of additional posterior fractures in combined anterior-posterior pelvic ring fractures in elderly patients

ObjectivesHistorically, pelvic ring fractures (PRF) are considered to occur predominantly in the anterior ring and therfore to be mechanically stable. Combined anterior and posterior (A + P) PRF are expected to be less mechanically stable and therefore to be associated with higher levels of pain and reduced mobility compared to isolated anterior fractures. The current study investigates the clinical relevance of combined A + P PRF in elderly patients.MethodsA prospective multicentre cohort study was conducted in patients >70 years of age with anterior PRF after low-energy trauma diagnosed on conventional radiographs. All patients underwent an additional CT-scan. Patients were divided into two groups; isolated anterior or combined A + P fractures. Patients were treated conservatively with adequate analgesia for at least one week. If patients could not be mobilised after conservative treatment, surgical fixation was performed. Numerical Rating Scale (NRS) pain scores, dependence on walking aids and Activities of Daily Living scores (ADL) were measured at 2–4 weeks, and 3, 6 and 12 months after fracture.Results102 patients (age 81.1 ± 7.6 years) were included. Isolated anterior fractures were diagnosed in 25 (24.5%) and A + P fractures in 77 (75.5%) patients. Baseline characteristics did not differ between the two groups. Most patients were successfully treated conservatively and 5 (4.9%) underwent percutaneous trans-iliac, trans-sacral screw fixation after failure of conservative treatment. At 2–4 weeks post trauma, patients with A + P fractures had similar median pain scores (3 (range 0–8) vs. 5 (0–10), p = 0.19) and ADL scores (85 (25–100) vs. 78.6 (5–100), p = 0.67), but were more dependent on walking aids (92.8% vs. 72.2%; p = 0.02) compared to patients with isolated anterior fractures. There were no significant differences at 3 months. At one year follow-up the median NRS pain and ADL scores for both fracture groups were 0 and 100, respectively. Mortality was 10.8%, and additional loss to follow-up was 17.6%.ConclusionsThe vast majority of elderly patients with PRF have combined A + P fractures. The clinical implications of additional posterior pelvic ring fractures in elderly patients appears to be limited.     

Cone beam computed tomography findings in temporomandibular joint of chronic qat chewers: Dimensional and osteoarthritic changes

The social habit of chewing qat (also known as khat) is widely practised in East Africa and the Arabian Peninsula. It has been linked with various oro-facial conditions, including temporomandibular joint disorders (TMD). This cross-sectional, comparative study sought to investigate the effects of qat chewing on temporomandibular joint (TMJ), using cone beam computed tomography (CBCT). A total of 85 Yemeni males were included. The participants were divided into two groups: Qat chewers (QC; n = 41) and non-qat chewers (NQC; n = 44). Relevant data were obtained using a structured questionnaire and standardised clinical examination. Additionally, CBCT images of the TMJs were obtained, and then, osteoarthritic changes and TMJ dimensions were analysed. SPSS 21 was used for statistical analyses, with a significant level was set at 0.05. Compared to NQC, a significantly higher proportion of QC presented with clinical signs of TMDs. The qualitative CBCT findings revealed significantly higher osteoarthritic changes in QC than in NQC: osteophyte (51.2% vs 22.7%; P = .008), subcortical sclerosis (48.8% vs 27.3%; P = .047), articular surface flattening (46.3% vs 6.8%; P = .009) and subcortical cysts (43.9% vs 4.5%; P < .001). However, CBCT quantitative findings (condylar dimensions) did not show significant differences between the two groups. The chewing side of the QC group showed slightly more changes compared to the non-chewing side. The results demonstrate that qat chewing has detrimental effects on TMJ manifested mainly as osteoarthritic changes. Further large-scale studies are recommended.     

小耳畸形分型与父母围孕期危险因素调查研究

目的调查围孕期危险因素对小耳畸形不同分型间的影响。方法选取2013年1月至2015年1月就诊于整形外科医院的600例患者为研究对象,向患者父母进行问卷调查,收集人口学及围孕期危险因素暴露情况。根据小耳畸形分型及严重程度分组,采用卡方、秩和检验行单因素分析,非条件Logistic回归行多因素分析。结果共收集572份问卷。单因素分析表明,性别、妊娠年龄、孕期腹部受外力冲击及孕期接受保胎治疗在不同分型小耳畸形间差异具有统计学意义(P<0.05)。多因素分析提示,孕期腹部受外力冲击可能是严重小耳畸形的独立危险因素(OR=2.157,95%CI:1.267~3.674),出生体质量在3~5 kg可能是保护因素(OR=0.112,95%CI:0.015~0.841;OR=0.110,95%CI:0.013~0.921)。结论围孕期多种危险因素暴露对小耳畸形发病的严重程度值得进一步关注和探讨。     

2018年某高校新生体质指数及生活习惯的调查分析

目的 了解江苏某高校2018级新生体质指数及生活习惯,分析生活习惯对体质指数的影响,为指导大学生养成健康生活习惯、塑造良好身体素质提供依据。方法 入学体检测量新生身高、体重,随机抽取部分专业学生完成生活习惯调查。结果 完成调查问卷的350名新生,体质指数正常、过轻、过重、肥胖者占比分别为57.71%、28%、10.29%和4%。男生体质指数高于女生(P<0.01),男生过重及肥胖检出率高于女生(P<0.05),女生过轻检出率高于男生(P<0.01)。完成调查问卷的新生中,65.43%每日规律三餐饮食,69.14%有每周运动的习惯。规律饮食组体质指数正常检出率高于非规律饮食组(P<0.05),每周运动3次及以上学生体质指数正常检出率高于其他学生(P<0.05)。超重学生睡眠满意度低于其他学生(P<0.05)。结论 新入学大学生体质指数过轻与超重问题并存,饮食及运动习惯有待改善,高校需重视体质指数监测,有针对性开展饮食及运动健康教育。     

健康相关生命质量高分组和低分组生活习惯和中医体质量表转换分比较

目的 探索健康相关生命质量高分组和低分组的生活习惯和中医体质转换分的差异。方法 从1 114例健康体检人群数据库中，分别抽取简明健康状况调查问卷（the MOS 36-item short form health survey, SF-36）的生理领域得分、心理领域得分的前27%（301例）和后27%（301例）作为高分组和低分组，比较两组的生活习惯和中医体质量表转换分。结果 SF-36生理领域和心理领域高分组和低分组的吸烟偏好比较，差异无统计学意义（P>0.05）；两组饮酒偏好、睡眠时间、中医体质量表转换分比较，差异具有统计学意义（P<0.05），其中高分组好饮酒者较多，睡眠时间为7～8 h者较多，平和质者较多，平和质转换分较高，8种偏颇体质转换分较低；心理领域高分组有运动习惯者较多（P<0.05），而生理领域高分组和低分组的运动习惯差异无统计学意义（P>0.05）。结论 SF-36高分组和低分组的生活习惯和中医体质因素存在一定差异，通过改善睡眠时间、运动习惯及偏颇体质可能会提高健康相关生命质量。
