Fingertip trauma in children from doors.

Fingertip and nailbed trauma caused by doors is common in children, occurring when fingers are either shut in the door itself or are trapped in the hinge as the door is closed. An audit was carried out over five months of all fingertip and nailbed injuries due to trauma from a door. One hundred and eighty eight children, 2% of all attendances in this period, had sustained such trauma, 39% of these occurring in children under four years of age. One hundred and forty seven children (75%) had sustained relatively minor soft-tissue injury to the finger, However the remaining forty seven (25%) of the injuries sustained were more serious e.g. Avulsion of the nail from the nailbed or amputation of part of the fingertip and 29 (15%) of all the cases required a general anaesthetic for exploration, cleaning and repair. The Plastic Surgery department followed up these 29 children and 71 Accident & Emergency follow-up appointments were generated by the remaining injuries. The incidence of significant injury was higher than expected and caused considerable distress to both the children and their parents, It is suggested that home safety protocols should feature advice on how to avoid these injuries.     

推进皮瓣修复指端缺损25例的护理体会

目的：探讨推进皮瓣修复指端缺损患者的护理方法。方法：回顾性分析25例创伤性指端缺损手术患者的护理资料。结果：经积极治疗和精心护理,术后23例皮瓣色泽红润,毛细血管充盈试验正常,成活可靠。2例术后2~3d出现不同程度皮瓣远端局部色泽暗红,予以皮瓣局部部分拆线减张、抬高患肢、保温、活血及抗血管痉挛等处理。其中1例皮瓣全部成活,1例皮瓣仍然少部分坏死,手术再次处理愈合。随访25例,优22例,良3例。结论：加强推进皮瓣修复指端缺损的护理,有利于促进皮瓣愈合,防止并发症的发生,是手术成功的重要保证。     

基于指尖温度变化的血管内皮功能评价设备研究

心血管病的传统诊断方法包括影像检测、生化检测等,操作复杂、成本高,难以满足家庭日常的预防监测需要。本文从血流介导血管内皮依赖性舒张及生物传热学角度出发,通过研究指尖在血流介导下的血液灌注率及温度变化规律,设计一种血管内皮功能评价设备,为开展心血管疾病早期预防诊断及心血管药物疗效评价提供一种无创、廉价、易用的设备。     

胸部损伤

胸部损伤包括胸壁软组织损伤、肋骨骨折、气胸、血胸、创伤性窒息、肺爆震伤、心脏挫伤、心脏破裂 (心包填塞 )等 ,治疗方法各异。下面对最常见的胸部损伤性疾病予以介绍。1　多根多处肋骨骨折根据外力对胸壁作用的部位与范围不同 ,发生骨折的肋骨数量与部位也不相同 ,最简单的为单根单折 ,范围大者可出现多根多折 ,有时甚至发生双侧多根多处肋骨骨折。多根多处肋骨骨折对病人的呼吸与循环影响较大 ,本节作重点阐述。1 1　病理生理　 (1 )纵隔移位 :由于胸壁软化无支撑作用而下陷 ,使负压减小 ,病人在静止状态下 ,纵隔向负压大的一侧 (健侧…     

指尖血糖较稳定的2型糖尿病动态血糖监测结果分析

目的:比较较稳定的指尖血糖与动态血糖监测系统的血糖结果.方法:选择2008-06/2009-01内分泌科37例住院患者,在指尖血糖监测示血糖相对平稳后佩戴雷兰动态血糖(DGMS).应用DGMS分析软件了解患者有无低血糖(<3.9 mmol/L)、高血糖(>11.1 mmol/L)、血糖漂移最大幅度.结果:血糖波动系数≤1.5组共9例,其中发生低血糖6例,高血糖2例,血糖漂移最大幅度为(6.82±1.85) mmol/L;>1.5组共28例,其中发生低血糖15例,高血糖25例,血糖漂移最大幅度为(10.9±3.22) mmol/L.两组比较,低血糖发生比例相近(P>0.05),发生高血糖及血糖漂移最大幅度在血糖波动系数>1.5组明显增多(均P<0.01),两组血糖漂移幅度最大患者均合并低血糖.结论:指尖血糖较好的患者仍须DGMS监测注意低血糖;高血糖和血糖漂移在血糖波动系数>1.5时显著增多;血糖漂移幅度越大越应注意有无低血糖.     

Adolescent running injuries

Nineteen teenagers between the ages of 13 and 18 years who had been running an average of 23.8 miles a week were attended for 25 musculoskeletal injuries. Diagnoses were similar to those seen in adults. Over 70% of the injuries involved the knee or leg. Girls had more leg injuries. All stress fractures occurred in the females despite their having less than one-half the weekly mileage of the boys (12 vs. 32 miles). Knee injuries were more common in boys. Over two-thirds of the injuries resulted from a training error. Methods for evaluation, treatment, and prevention of adolescent running injuries are discussed.
