Lumbar Spinal Cord Stimulation Can Improve Muscle Strength and Gait Independently of the Analgesic Effect: A Case Report

Spinal cord stimulation (SCS) is widely used for pain relief in patients with failed back surgery syndrome (FBSS), and muscle weakness is a common finding in patients with chronic pain. We present here a single case report of a 47‐year‐old woman, who, after SCS for FBSS, had continuous improvement in lower leg muscle strength and gait, but only transient and minimal pain relief. To the authors’ knowledge, this is only the second published case report of significant improvement in “motor” function, independent of the analgesic effect following SCS in FBSS. If SCS, in fact, does improve muscle strength, new strategies for the management of patients with chronic pain might be opened up. Further studies are needed to verify this hypothesis.

Peyronie's disease:a silent consequence of diabetes mellitus

Aim:To investigate the clinical characteristics of patients with Peyronie's disease(PD)and diabetes mellitus(DM).Methods:During an 8-year period,a total of 307 men seen at our outpatient clinic were diagnosed with PD.Clinicalcharacteristics,penile deformities and the erectile status of patients with PD and DM together(n=102)were retro-spectively analyzed and compared to patients with PD alone with no risk factors for systemic vascular diseases(n=97).Results:The prevalence of PD among men with DM and sexual dysfunction was 10.7%.The mean ageof diabetic patients with PD was(55.9±8.9)years;in the no risk factor group it was(48.5±9.0)years(P<0.05).The median duration of DM was 5 years.The majority of diabetic patients with PD(56.0%)presented in the chronicphase(P<0.05),and they were more likely to have a severe penile deformity(>60°)than the no risk factor group(P<0.05).In the diabetic group,the most common presenting symptom was penile curvature(81.4 %),followedby a palpable nodule on the shaft of the penis(22.5%)and penile pain with erection(14.7 %).A total of 19.6 % ofpatients were not aware of their penile deformities in the diabetic group.Erectile function,provided by history and inresponse to intracavernosal injection and a stimulation test,was significantly diminished in patients with PD and DM(P<0.05).Conclusion:DM probably exaggerates the fibrotic process in PD.Diabetic patients with PD have ahigher risk of severe deformity and erectile dysfunction(ED).PD seems to be a silent consequence of DM andshould be actively sought in diabetic men.(Asian J Androl 2006 Jan;8:75-79)     

Morbidity Associated With High Gastrocnemius Recession: Retrospective Review of 126 Cases

To evaluate morbidity associated with surgical lengthening of the gastrocnemius, medical records were reviewed retrospectively for 126 patients (mean age, 49.7 years; range, 8-78 years) who had undergone open gastrocnemius recession. Ten patients had isolated recession; 116 had gastrocnemius recession with an additional foot or ankle procedure on the ipsilateral limb. During a mean follow-up period of 19 months (range, 6-50 months), all patients were examined for any postoperative complications associated with the recession. Complications were defined as the presence of postoperative infection, wound dehiscence, nerve problems, decreased muscle strength, scar problems, or calcaneus gait (overlengthening). Uncomplicated outcome was defined as absence of all these complications and return to regular activity, both occurring during a follow-up of at least 6 months. Postsurgical complications developed in 9 (6%) of the 126 patients: 6 (4%) had scar problems, 2 (1.33%) had wound dehiscence, 2 (1.33%) had infection, 3 (2%) had nerve problems, and 1 (0.67%) developed complex regional pain syndrome. No patient complained of either a limp or gait disturbance. Neither persistent decrease in muscle strength nor calcaneus gait was seen. These data suggest that the open gastrocnemius recession procedure has low associated morbidity.     

椎管扩大成形术治疗腰椎管狭窄

目的：探讨椎管扩大成形术治疗腰椎管狭窄的效果。方法：椎板减压后复位，用棘突或髂骨植于一侧开槽处扩大椎管，并进行椎板及关节突关节植骨，对54例随访病人的手术前后临床表现及X线和CT进行比较。结果：随访6—39个月，临床优良率为81．1％。随访X线片显示椎板明显后移，CT测量与术前对比显示椎管内径扩大明显。结论：椎管扩大成形术操作简单，效果满意，术后并发症少，是治疗腰椎管狭窄的又一选择。     

亚低温治疗重型颅脑损伤中脑组织氧分压的临床意义

目的观察亚低温治疗重型颅脑损伤过程中患者颅内压及脑组织氧分压的变化及临床意义。方法将80例急性重型颅脑损伤患者,随机分为亚低温治疗组(40例)和对照组(40例)。亚低温组入院后或术后立即给予亚低温治疗,保持肛温在32~34℃,持续24h~5d;对照组给予常规治疗。两组均观察颅内压(ICP)和脑组织氧分压(PbtO2)变化。结果亚低温组治疗后,ICP明显下降,PbtO2逐渐升高,与对照组相比有显著性差异。结论亚低温治疗能降低脑外伤后增高的ICP,提高PbtO2;伤后24h内持续PbtO2<5mmHg预示患者预后不良。

肾移植术患者连续腰麻的效果

目的评价肾移植术患者连续腰麻（CSA）的效果。方法择期肾移植术患者24例，ASAⅢ级，随机分为3组（n=8），DCEA组：L1-2与L3-4间隙硬膜外穿刺，注入2％利多卡因试验剂量5ml，初始剂量10—20ml（0．75％布比卡因＋2％利多卡因，1：1混合液）；CSEA组：L1-2间隙硬膜外穿刺，L3.4间隙经硬膜外针行腰麻穿刺，注入重比重0.5％布比卡因10～13mg，调节体位和硬膜外给药量（0．75％布比卡因＋2％利多卡因，1：1混合液）；CSA组：L3.4间隙经硬膜外针行腰麻穿刺，注入重比重0．5％布比卡因10～13mg，根据阻滞平面给药2—4mg，次。3组目标阻滞平面k，记录入手术室后（基础值）和首剂量局麻药注入后1、5、10、15minSP、DP、MAP、HR。于麻醉前（T1）、移植肾植入髂窝后即刻（T2）、手术结束（T3）测血糖；记录开始注入局麻药至出现满意阻滞平面的时间、肌松程度、肾脏植入髂窝后患者不适感和局麻药总量。结果与CSEA组比较，阻滞平面达T6时间DCEA组延长（P〈0．05），局麻药总量DCEA组增多，CSA组减少（P〈0．05）。3组血糖比较差异无统计学意义（P〉0．05）。镇痛效应及肌松程度CSA组优于DCEA组和CSEA组。结论与硬膜外阻滞和脊椎．硬膜外联合阻滞相比，肾移植术患者连续腰麻产生较好的镇痛、肌松效果，且局麻药用量较少。
