Profound bilateral deafness complicating aortic arch surgery

Hearing loss is a rare complication of cardiac surgery; bilateral profound deafness has never been reported in this setting. A 45-year-old male presented with profound bilateral sudden deafness following arch surgery and frozen elephant trunk. Patient’s presentation, surgery details and aetiological mechanisms are discussed.     

燕滨扶正胶囊治疗代偿期及失代偿期肝硬化临床疗效观察研究

目的 研究中药燕滨扶正胶囊治疗肝硬化（代偿期或失代偿期）临床疗效。方法 选择代偿期及失代偿期肝硬化患者41例,随机分为治疗组（21例）及对照组（20例）。治疗组给予燕滨扶正胶囊1500 mg/次,口服,2次/日。对照组给予扶正化瘀胶囊2500 mg/次,3次/日。两组疗程均为48周。两组依据病情给予抗病毒,护肝降酶、对症支持等一般治疗（替比夫定、甘利欣、消炎利胆片、茵栀黄胶囊等）,观察两组患者症状、血常规、肝功能、门静脉宽度、腹水、肝脏及脾脏形态。结果 中药燕滨扶正胶囊联合抗病毒药物可使代偿期及失代偿期肝硬化患者门静脉宽度、脾肿大回缩或复常,可使纤维化指标复常或大幅下降且肝脏功能好转或复常。结论 燕滨扶正胶囊可改善肝硬化。     

Tissue fixation security in transosseous rotator cuff repairs: A mechanical comparison of simple versus mattress sutures

The primary purpose of this investigation was to compare tissue fixation security by simple sutures versus mattress sutures in transosseous rotator cuff repair. These two repair techniques were each performed in 17 human cadaver shoulders, with two bone tunnels being used for the repair by two simple sutures and two other bone tunnels being used for the repair by one mattress suture. The repairs were loaded to failure in a servohydraulic materials test system. Rotator cuff repair by simple sutures was found to be significantly stronger than repair by mattress sutures (P = .0007). The average ultimate load to failure for the simple suture construct (189.62 N) was 39.72% greater than that for the mattress suture construct (135.71 N). Most of the failures occurred by suture breakage at the knot. Load-sharing by multiple suture tails and multiple knots in the simple suture configuration likely contributed to its superior strength characteristics compared with the mattress suture configuration.     

前后路联合手术治疗髋臼双柱骨折疗效分析

目的:探讨前后路联合手术治疗髋臼双柱骨折的效果并分析影响疗效的相关因素。方法:2007年8月至2009年7月收治髋臼双柱骨折患者19例,男13例,女6例;年龄27～52岁,平均39.6岁。高位双柱骨折11例,低位双柱骨折8例,双柱骨折累及骶髂关节1例。受伤至手术时间4～11 d,平均5.8 d。患者均采用前后联合入路手术,重建钢板和螺钉内固定。结果:除1例死亡外本组全部获随访,随访时间12～18个月,平均13.6个月。关节功能根据Harris评分标准,术后功能优9例,良7例,可2例。结论:经前后路联合切开复位内固定治疗髋臼双柱骨折疗效满意。     

改良性治疗法联合西地那非治疗勃起功能障碍维吾尔族患者2505例回顾性分析

目的:性治疗法目前尚未普及,本研究旨在评价性治疗法联合西地那非治疗勃起功能障碍(ED)的疗效。方法:根据治疗方法的不同将在本院治疗随访过的3130例维吾尔族ED患者分成2组。对照组625例,单纯口服西地那非3个月;试验组2505例,采用性治疗法联合西地那非治疗3个月。采用国际勃起功能问卷表(IIEF-5)在各组治疗前、后进行疗效评估,并随访12个月。结果:对照组治疗前、后及在6个月、12个月随访的IIEF-5评分分别为12.80±3.76、18.10±2.61、17.35±2.73和16.64±2.63;试验组治疗前、后及在6个月、12个月随访的IIEF-5评分分别为12.73±3.52、19.06±4.07、19.86±2.42和20.47±2.38。两组治疗前后IIEF-5评分自身对比差异均有显著性(P<0.05)。组间比较,试验组较对照组6个月和12个月随访IIEF-5评分均有显著性差异(P<0.05)。结论:性治疗法联合西地那非治疗ED的效果优于单纯西地那非治疗,并在12个月的随访中稳定性良好。     

Whites and African-Americans in headache specialty clinics respond equally well to treatment

This study sought to determine if Whites and African-Americans respond similarly to headache treatment administered in 'real-world' headache specialty treatment clinics. Using a naturalistic, longitudinal design, 284 patients receiving treatment for headache disorders completed 30-day daily diaries that assessed headache frequency and severity at pretreatment and 6-month follow-up and also provided data on their headache disability and quality of life at pretreatment and 1-, 2- and 6-month follow-up. Controlling for socioeconomic status and psychiatric comorbidity, hierarchical linear models found that African-Americans and Whites reported significant reductions in headache frequency and disability and improvements in life quality over the 6-month treatment period. African-Americans, unlike Whites, also reported significant decreases in headache severity. Nevertheless, Africans-Americans had significantly more frequent and disabling headaches and lower quality of life after treatment relative to Whites. Although Whites and African Americans responded favourably to headache treatments, more efficacious treatments are needed given the elevated level of headache frequency that remained in both racial groups following treatment.
