腕关节融合钢板内固定术的临床疗效

目的评价腕关节融合钢板内固定术的临床疗效。方法2000年7月-2004年12月，采用腕关节融合钢板内固定术治疗创伤性腕关节炎21例。随访内容包括腕关节疼痛程度、手指关节活动度、握力和x线片。根据Buck—Gramcko／Lohrnanrm评分表评价腕关节总体功能，DASH调查表评价腕关节融合术对患者日常活动及生活质量的影响。结果术后21例获得随访，平均随访时间为20个月。术后患侧腕部疼痛值平均为1．5（术前4．5），12例掌指关节和lO例拇指指间关节出现轻微背伸功能障碍，腕部握力为30kg（健侧为38kg）。x线片示腕关节全部骨性融合。Buck—Gramcko／Lohmanrm评分值为8．7，其中优5例、良10例，中6例。DASH值为32，DASH调查表结果表明腕关节融合术后部分日常活动受限。结论腕关节融合钢板内固定成功率高，腕关节疼痛明显减轻，但术后腕关节部分功能丧失。     

精神分裂症患者的记忆功能障碍与精神症状和疗效的关系

目的　探讨精神分裂症记忆功能与精神症状和疗效的关系。方法　对 88例精神分裂症患者分别给予奎的平、舒必利、维思通治疗。采用PANSS量表评定精神症状 ,修订韦氏成人记忆量表 (WMS -RC)测查记忆功能(治疗前用甲式 ,治疗后用乙式 )分别于治疗前、治疗后第 6周末各评一次 ,并采用Pearson相关分析和多元逐步回归进行分析。结果　治疗前记忆商数与阴性症状、一般病理性症状、PANSS总分呈显著负相关 ,与阳性症状无相关性 ;多元逐步回归分析显示治疗前记忆商数与阴性症状关系最密切 ;治疗后记忆商数增加值与阴性症状的减分值呈显著正相关 (r=0 337,P <0 0 1,88例 ) ;治疗前记忆商数与治疗第 6周末的阴性症状减分值、一般病理性症状减分值呈显著负相关 (r =- 0 2 6 5 ,P <0 0 5 ;r =- 0 2 35 ,P <0 0 5 ,88例 )。结论　本研究支持精神分裂症记忆损害与阴性症状存在相似的病理机制假说。     

糖皮质激素治疗急性呼吸窘迫综合征58例临床分析

目的 评价糖皮质激素在急性呼吸窘迫综合征（ARDS）救治中的作用。方法 回顾性分析我院1992年8月－2001年5月58例临床确诊为ARDS患的临床资料，其中肺内型ARDS组（ARDSp）18例，肺外型ARDS组（ARDSexp)40例。各组再以使用地塞米松情况分为：≥30mg/d组，＜30mg/d组和非激素治疗组。结果 各组病情程度相当，组间APACHE Ⅱ评分比较差异无显性（P＞0．05）。激素用量≥30mg/d组与＜30mg/d组及非激素治疗组比较，病情改善天数及使用呼吸机治疗天数均明显缩短，差异有显性（P＜0．01）。58例患总病死率为20．7％，ARDSp组，ARDSexp组中激素用量≥30mg/d组的病死率分别为14．3％，11．5％，均低于ARDSp与ARDSexp组的平均病死率（分别为22．2％，20．0％）。所有病例未见感染扩散或加重。结论 早期，足量，适当疗程应用糖皮质激素治疗ARDS可及时逆转过度失控的炎症反应，缓解病情，降低病死率。     

Madigan前列腺切除术对前列腺增生症的治疗效果

Risk of death from acute pancreatitis

Summary Conclusions The analysis of all the data available in 192 patients at 24 h from admission shows that only serum glucose above 250 mg/dL (13.88 mmol/L) and serum creatinine above 2 mg/dL (176.8 μmol/L) are prognostic factors of death (P<0.0001). When, however, pathological chest X-rays are also considered in a subset of 149 patients, these and serum creatinine are prognostic factors of death with odds ratios of 2.9 (95% CL 1.3–6.3) and 9.4 (95% CL 2.2–40.7), respectively (P<0.0001). Background In patients suffering from acute pancreatitis, neither Ranson scores nor Glasgow criteria evaluation at 24 h yield a sufficiently reliable prognosis of the risk of death from the first acute attack. Methods After excluding posttraumatic, postsurgical, and post-ERCP acute pancreatitis, we selected 192 consecutive patients admitted in the first instance to our center for a first attack, distinguishing between patients who died and patients who survived. We used Cox's model to analyze the prognostic weight of variables available within 24 h of admission (sex, age, alcohol intake, smoking habits, 17 biochemical tests, body mass index, chest X-rays, body temperature, and shock status). Results Seventeen (8.8%) patients died; mortality showed a decreasing trend over the period of years considered and was correlated, among other things, with necrotizing type of pancreatitis, idiopathic etiology, and shock status on admission.     

Effectiveness of electroconvulsive therapy in community settings.

BACKGROUND: Clinical trials indicate that electroconvulsive therapy (ECT) is the most effective treatment for major depression, but its effectiveness in community settings has not been examined. METHODS: In a prospective, naturalistic study involving 347 patients at seven hospitals, clinical outcomes immediately after ECT and over a 24-week follow-up period were examined in relation to patient characteristics and treatment variables. RESULTS: The sites differed markedly in patient features and ECT administration but did not differ in clinical outcomes. In contrast to the 70%-90% remission rates expected with ECT, remission rates, depending on criteria, were 30.3%-46.7%. Longer episode duration, comorbid personality disorder, and schizoaffective disorder were associated with poorer outcome. Among remitters, the relapse rate during follow-up was 64.3%. Relapse was more frequent in patients with psychotic depression or comorbid Axis I or Axis II disorders. Only 23.4% of ECT nonremitters had sustained remission during follow-up. CONCLUSIONS: The remission rate with ECT in community settings is substantially less than that in clinical trials. Providers frequently end the ECT course with the view that patients have benefited fully, yet formal assessment shows significant residual symptoms. Patients who do not remit with ECT have a poor prognosis; this underscores the need to achieve maximal improvement with this modality.
