股骨近端不同平面皮质骨厚度值、X射线灰度值与女性髋部脆性骨折的相关性

文题释义：脆性骨折：是指在无创伤或较微创伤情况下引起的骨折，一般是指在平地或人体站立高度下活动过程中发生的骨折，X射线下常可见骨骼有骨质疏松征象，也称为骨质疏松性骨折。 髋部骨折：是指发生在髋部及周围的骨折，包括股骨颈骨折、股骨转子间骨折、转子间骨折及髋臼骨折等，是骨质疏松性骨折最常发生的骨折部位，患者常因高龄且伴有基础疾病而1年内死亡率可达50%，5年存活率为20%。 背景：随着人口老龄化，脆性骨折疾病受到临床越来越多的关注，骨密度值的单独使用已经不能满足临床对脆性骨折的风险评估。目前骨皮质厚度作为评估脆性骨折发生风险的新方向和新方法之一，受到越来越多学者的研究和讨论。 目的：探讨在X射线DR摄影下，股骨近端不同平面骨皮质厚度值、X射线灰度值与50岁以上女性髋部脆性骨折的相关性，以此探寻股骨近端不同平面中，用于预测女性髋部脆性骨折发生风险最合适的测量平面。 方法：依照纳入标准收集2018年7月至2019年6月在广西医科大学第九附属医院放射科行X射线DR骨盆正位片检查的50岁以上女性患者100例的相关临床资料。所有患者对试验方案均知情同意，且得到医院伦理委员会批准。股骨近端骨皮质厚度值的测量平面设计为股骨颈中段、小转子上1 cm以内和小转子下1 cm以内，共3个测量平面。X射线灰度值测量以大转子和小转子的中点连线作为矩形对角线取矩形区域测量。 结果与结论：①50-64岁年龄组记为A组，65岁及以上年龄组记为B组，每组各50例；② B组患者的小转子上1 cm以内和小转子下1 cm以内平面的骨皮质厚度值、X射线灰度值比A组低，骨折率比A组高，差异均有显著性意义(P < 0.05)；而股骨颈中段平面的骨皮质厚度值2组间比较差异无显著性意义(P > 0.05)；③骨皮质厚度值的测量平面比较，骨皮质厚度测量值在整体上由高到低依次为小转子下1 cm以内、小转子上1 cm以内和股骨颈中段平面，差异有显著性意义(P < 0.05)；④观察对象小转子下1 cm以内及小转子上1 cm以内骨皮质厚度值、X射线灰度值、年龄，与脆性骨折相关系数依次为-0.303，-0.205，-0.272及0.346(P < 0.05)，但股骨颈中段平面皮质骨厚度与脆性骨折无明显相关性(P > 0.05)；⑤A组中骨折和非骨折患者小转子上1 cm以内和小转子下1 cm以内测量平面的骨皮质厚度值比较差异有显著性意义(P < 0.05)；B组中骨折和非骨折患者各指标比较差异均无显著性意义(P > 0.05)；在50岁以上的所有患者中，骨折和非骨折患者各测量平面的骨皮质厚度值和X射线灰度值的比较差异均有显著性意义(P < 0.05)；⑥说明骨皮质厚度值变薄，X射线灰度值变小，则髋部脆性骨折可能性变高。利用股骨近端骨皮质厚度评估50岁以上女性髋部脆性骨折风险时，推荐在股骨小转子下1 cm以内平面进行测量。 ORCID: 0000-0003-1961-7468(覃海阔) 中国组织工程研究杂志出版内容重点：人工关节；骨植入物；脊柱；骨折；内固定；数字化骨科；组织工程     

安徽省儿童青少年高血压与体脂百分比关联性研究

目的 了解安徽省儿童青少年高血压的检出情况,分析其与体脂百分比的关联性。方法 对安徽省8 890名7~17岁中小学生进行了血压和皮褶厚度的测量,参考《中国高血压防治指南(2010年修订版)》中儿童高血压诊断标准评价儿童高血压情况,通过皮褶厚度计算体脂百分比。采用t检验、χ²检验和logistic回归分析体脂百分比与高血压的关联。结果 安徽省7~17岁中小学生高血压患病总人数(率)为1 210人(13.6%)。城市男生高血压患病率高于乡村男生,城市女生高血压总患病率高于乡村女生,城市男生高血压患病率高于城市女生,乡村男生高血压患病率高于乡村女生,差异均有统计学意义(χ²值分别为36.36、7.79、42.10和13.77,P<0.01)。城市男生体脂百分比高于乡村男生,城市女生显著高于乡村女生,差异均具有统计学意义(P<0.05)。男女生在P₄₀~组和P₆₀~组OR值分别为1.65(95% CI:1.12~2.45)和1.75(1.27~2.42),男女生分别从体脂百分比P₄₀和P₆₀开始患病风险明显增加,且男女生的高血压患病风险总体上随着体脂百分比的增加而上升。结论 高体脂百分比会增加儿童青少年高血压患病风险。     

癫痫患者服用卡马西平对颈动脉内中膜厚度的影响

目的研究癫痫患者服用卡马西平对颈动脉内中膜厚度(carotid artery intima-media thickness,CA-IMT)的影响。方法选择2012-05—2014-05在我院接受治疗的癫痫患者84例,根据随机数字法分成口服卡马西平组42例(A1组)及癫痫未治疗组(A2组),另选同期在我院接受健康体检的志愿者42例为对照组(B组),对比各组血脂、Hcy及CRP水平,各组CA-IMT水平,分析影响CA-IMT水平的危险因素。结果 A1组TC、TG、LDL-C、Hcy及CRP水平均分别显著高于A2组及B组,差异均有统计学意义(均P0.05)。A1组右侧CA-IMT、左侧CA-IMT及平均CA-IMT水平均分别显著高于A2组及B组,差异均有统计学意义(均P0.05)。Logistic回归分析显示,用药时间及用药总剂量均为影响CA-IMT水平的危险因素。结论癫痫患者经卡马西平治疗对血脂水平具有一定的影响,同时还可增加CA-IMT水平,值得临床应用时关注。     

Reconstruction for axillary hidradenitis suppurativa using one‐stage local tissue rearrangement: A retrospective analysis of 53 cases

Wide local excision offers a potential cure for severe axillary hidradenitis suppurativa. However, the gold standard for reconstruction has yet to be defined. Here, we describe our rotation advancement flap technique, which allows for one‐stage closure of large axillary defects, with minimal functional morbidity to the axilla. We performed a retrospective review of all patients who underwent one‐stage surgical management for axillary hidradenitis suppurativa at a single‐centre tertiary care hospital from 2009 to 2018. We identified 34 patients, with a total of 53 operative sites. The majority were female (85%) with a mean age of 31 years and body mass index 35 kg/m². The median defect size was 84 cm² and the majority were treated using the rotation advancement flap technique (86%). A quarter of operative sites experienced minor complications with only one requiring re‐operation. At a median follow‐up of 32 months, two (4%) sites showed decreased range of motion. However, all patients had achieved remission without any further recurrence of disease. We describe a one‐stage rotation advancement flap technique for management of moderate to severe hidradenitis suppurativa that achieves a high local cure rate, minimal functional morbidity, and acceptable wound complication rates.     

Inter-ocular asymmetry of retinal parameters in Caucasian healthy children and young adults measured with optical coherence tomography

AIM: To evaluate retinal parameters in a sample of healthy young Caucasian adults to define the normal or physiological range of inter-ocular asymmetry in this particular age and ethnic group. METHODS: Study sample consisted of 37 Caucasian children and young adults aged between 12 and 23y (spherical equivalent from -3.00 D to +4.00 D, anisometropia <0.5 D and axial length differences <0.3 mm). Normal inter-ocular asymmetry values were determined and 95% inter-ocular difference tolerance values were obtained. RESULTS: Statistically significant inter-ocular differences were found in mean (P=0.003) and superior (P=0.008) retinal nerve fiber layer (RNFL) thickness, as well as in central macular thickness (P=0.039), with larger values in the left eye in all instances, and with tolerance limits of inter-ocular asymmetry of -9.00 μm to 6.00 μm, -28.00 μm to 9 μm and -39.00 μm to 29.00 μm, respectively. In addition, statistically significant differences were found between males and females in mean thickness of the RNFL in the right eye (P=0.020). CONCLUSION: The exploration of the normal asymmetries of the retina may be an effective approach to further understand myopia onset and progression, which is particularly relevant in this age group. Differences in instrumentation and sample characteristics compromise direct comparison with published research and warrant the need for further studies.
