治疗老年重症呼吸衰竭42例临床分析

目的：探讨机械通气联合支气管肺泡灌洗（BAL）在治疗老年重症呼吸衰竭的作用。方法：选择常规治疗后病情无缓解的重症老年呼吸衰竭患者42例。建立人工气道行钡械通气治疗12～24h后，低氧血症纠正不理想，气道压力偏高，痰多者，应用加温至37℃生理盐水加庆大霉素、地塞米松及爱全乐经纤支镜行BAL，吸除呼吸道粘稠分泌物，每日一次，连续3—5天。结果：42例患者中，37例通气24h，经支气管肺泡灌洗后，气道压力下降，临床症状好转，缺氧及二氧化碳滞留得到改善，病原菌得到明确，成功脱机出院。结论：对老年重症呼吸衰竭在机械通气的基础上联合支气管肺泡灌洗是治疗呼吸衰竭安全有效的重要措施，值得临床应用。     

特发性脊柱侧凸PUMC分型的可重复性及可信度研究

目的:探讨特发性脊柱侧凸PUMC(协和)分型系统的一致性,并对影响分型一致性的因素进行分析.方法:随机选取南京鼓楼医院2004年～2006年治疗的80例特发性脊柱侧凸患者,其中男性15例,女性65例,平均年龄14.6岁(10～18岁),均有完整的术前站立位正侧位X线片及仰卧位左右Bending片共四张.由4名脊柱外科专科医生分别根据PUMC(协和)分型标准进行分型,2周后此4位医生分别对这些患者的X线片再次进行分型,收集分型结果分别作可信度和可重复性分析,计算Kappa值检验一致性并对影响分型一致性的因素进行统计分析,结果:80例患者均可用PUMC分型,分型可信度平均Kappa值为0.801,可重复性Kappa值为0.878.PUMC分型不一致中包括上胸弯的界定18次;胸弯明显时,代偿性与结构性腰弯的界定15次;腰弯明显时,代偿性与结构性胸弯的界定18次;单弯顶点的判断20次;测量角度的差异18次.结论:PUMC(协和)分型学习曲线相对较短,易于掌握且具有良好的可信度和可重复性.

A randomized pilot study in Type 1 diabetes complicated by severe hypoglycaemia, comparing rigorous hypoglycaemia avoidance with insulin analogue therapy, CSII or education alone.

AIM: To determine potential for amelioration of recurrent severe hypoglycaemia without worsening in overall control in individuals with long-standing Type 1 diabetes (T1DM). METHODS: Twenty-one people with T1DM characterized by altered hypoglycaemia awareness and debilitating severe hypoglycaemia were randomized in a pilot 24-week prospective study to optimized analogue therapy (ANALOGUE; lispro/glargine); continuous subcutaneous insulin infusion therapy (CSII; lispro); or re-education with relaxation of blood glucose targets on existing conventional insulin regimen (EDUCATION). Glycaemic profiles and duration of biochemical hypoglycaemia were measured by continuous subcutaneous glucose monitoring and self-monitored blood glucose. RESULTS: Further severe hypoglycaemia was prevented in five participants (71%) in each group (P = 0.06). Incidence of severe hypoglycaemia was: 0.6 (ANALOGUE), 0.9 (CSII), and 3.7 (EDUCATION) episodes per patient year. Restoration of hypoglycaemia awareness was confirmed by validated questionnaire in three (43%) ANALOGUE, four (57%) CSII and five (71%) EDUCATION patients. Glycated haemoglobin (HbA1c) was significantly improved in the ANALOGUE group between weeks 0 and 24 (8.6 +/- 1.1 vs. 7.6 +/- 0.8%; P = 0.04 for change). Non-significant improvement was seen in the CSII group (8.5 +/- 1.9 vs. 7.4 +/- 1.0%; P = 0.06). No change in HbA1c was seen in the EDUCATION group (8.5 +/- 1.1 vs. 8.3 +/- 1.0%; P = 0.54). There were no episodes of diabetic ketoacidosis or any other adverse events in any group. CONCLUSIONS: In this pilot randomized trial comparing optimized ANALOGUE, CSII or EDUCATION alone in unselected individuals with recurrent severe hypoglycaemia, we show potential for restoring hypoglycaemia awareness and preventing further severe hypoglycaemia with concomitant improvement in glycaemic control in ANALOGUE and CSII groups.     

退变性症状性腰椎侧凸的手术治疗

[目的]探讨后路椎管减压、椎弓根螺钉间断固定、椎间植骨融合、矢状位重建术式治疗退变性症状性腰椎侧凸的临床效果。[方法]1999年1月-2006年4月，采用经后路椎管减压、椎弓根螺钉间断固定、椎间植骨融合、矢状位重建术式治疗退变性症状性腰椎侧凸37例，男21例，女16例；年龄51—82岁，平均62．6岁。所有病例拍摄腰椎正侧位片及Bending片，常规备CT和MRI。根据患者下肢症状行全椎板或半椎板减压，神经根扩大，椎间植骨融合及椎弓根螺钉间断固定。[结果]本组病例均获随访（1—6年，平均2年零7个月），术后临床症状均明显缓解，按JOA评分，手术疗效优良率91．9％，侧凸平均矫正率54．8％。随访期间无明显矫正度数及椎间隙高度丢失，术后3个月、1年复查X片内置物无松动及断裂，植骨融合时间平均11．6周。[结论]对于退变性症状性腰椎侧凸患者：（1）采取个体化治疗，年龄不是绝对手术禁忌证，病程长短不是决定手术疗效的重要指标；（2）后路椎管减压、椎弓根螺钉间断固定、椎间植骨融合、矢状位重建术是安全有效的理想术式。     

Osteoporosis in severe congenital neutropenia treated with granulocyte colony-stimulating factor

Recombinant human granulocyte colony-stimulating factor (G-CSF) has substantially improved life expectancy for children with severe congenital neutropenia (SCN). Severe osteoporosis, reported in this population, may relate to the disease process, or be a therapeutic side-effect. This report details bone loss, quantitated absorptiometrically and histomorphometrically, in a child with SCN and vertebral collapse, and the positive response to anabolic steroid and bisphosphonate therapy.
