Proviewer一次性使用软组织阻隔装置在颅内手术操作有效性及安全性的随机对照临床研究

目的评价Proviewer一次性使用软组织阻隔装置在颅内手术操作过程中的有效性和安全性,为推广应用提供科学依据。方法采用前瞻性随机对照的临床研究方法,以应用Proviewer一次性使用软组织阻隔装置为试验组,以传统脑压板手术为对照,比较两组手术间临床疗效及手术安全性的差异。结果从2011年06月至2011年12月,共有19例患者纳入全分析集(FAS),其中试验组10例,对照组9例。因为年龄违反入选标准而排除2例,故符合方案集(PPS)共有17例,其中试验组9例,对照组8例。纳入安全性分析集的19例,其中试验组10例,对照组9例。以临床效果综合计分作为主要疗效指标。试验组和对照组比较,在FAS和PPS的差异均具有统计学意义(P<0.05),试验组优于对照组。进一步对视野观察计分和主述性观察计分指标进行比较,表现出相同的结果,即在FAS和PPS的差异均具有统计学意义(P<0.05),试验组优于对照组。以不良事件作为安全性评价指标。试验组共出现1人(10.00%),对照组共出现1人(11.11%)。两组不良事件发生率差别无统计学意义(P>0.05)。所有不良事件均与治疗器械无关,且在病人出院前消除。结论Proviewer一次性使用软组织阻隔装置与传统脑压板相比,在颅内手术操作过程中能为手术者提供更好的观察视野、便利的手术操作,减少术中出血量;且未产生与医疗器械有关的不良反应,有较高的临床应用价值,值得临床推广使用。     

中西医结合治疗眼眶骨折致眼眶瘀肿及眶下神经知觉障碍临床观察

目的 :观察早期运用中西医结合疗法治疗眼眶骨折致眼眶瘀肿及眶下神经知觉障碍的临床疗效。方法 :将76例(82眼)眶骨骨折患者按随机数字表法分为对照组和治疗组各38例(41眼)。对照组予抗生素、地塞米松静脉滴注,B族维生素及甲钴胺片口服,并对症治疗;治疗组在对照组的基础上辨证运用自拟经验方眼眶骨折1号方、眼眶骨折2号方。观察两组治疗后眼眶瘀肿及眶下神经知觉障碍改善情况,综合评价疗效。结果:治疗组软组织肿胀、眼睑瘀血、结膜下瘀血平均消退时间均短于对照组,差异有统计学意义(P<0.05)。眶下神经知觉障碍改善情况,治疗组显效6例,有效12例,无效0例,总有效率100%;对照组显效2例,有效12例,无效6例,总有效率70%;治疗组疗效明显优于对照组,差异有统计学意义(P<0.05)。结论:早期运用中西医结合疗法治疗眶骨骨折安全、有效,能加快眶周软组织损伤修复,缩短眼眶瘀肿消退时间,改善眶下神经知觉障碍。与单纯西医治疗比较,中西医结合疗法能缩短疗程、提高临床疗效。     

Imaging update on soft tissue sarcoma

Soft tissue sarcomas (STS) are rare tumours presenting as soft tissue lumps. Ultrasound is often the primary modality for the initial assessment, with MRI the mainstay for lesion characterisation. PET/CT along with other emerging MRI sequences are used in certain situations as an adjunct and problem solving tool in STS staging and assessment of disease recurrence. Recent advances include the promise of whole body MRI, hybrid PET/MRI, diffusion weighted imaging, dynamic contrast enhanced MRI and advances in artificial intelligence. This article discusses current concepts in extremity STS imaging and highlights recent advances.     

Inhalation device options for the management of chronic obstructive pulmonary disease

Chronic obstructive pulmonary disease (COPD) is characterized by chronic respiratory symptoms and airflow limitation, resulting from abnormalities in the airway and/or damage to the alveoli. Primary care physicians manage the healthcare of a large proportion of patients with COPD. In addition to determining the most appropriate medication regimen, which usually includes inhaled bronchodilators with or without inhaled corticosteroids, physicians are charged with optimizing inhalation device selection to facilitate effective drug delivery and patient adherence. The large variety of inhalation devices currently available present numerous challenges for physicians that include: (1) gaining knowledge of and proficiency with operating different device classes; (2) identifying the most appropriate inhalation device for the patient; and (3) providing the necessary education and training for patients on device use. This review provides an overview of the inhalation device types currently available in the United States for delivery of COPD medications, including information on their successful operation and respective advantages and disadvantages, factors to consider in matching a device to an individual patient, the need for device training for patients and physicians, and guidance for improving treatment adherence. Finally, the review will discuss established and novel tools and technology that may aid physicians in improving education and promoting better adherence to therapy.     

封闭式负压吸引、氧气、臭氧联合治疗软组织缺损的疗效观察

目的探讨封闭式负压吸引、氧气、臭氧联合治疗软组织缺损的临床疗效。方法 40例软组织缺损患者随机分为对照组（根据病情分别给予游离植皮覆盖、二期缝合、局部皮瓣移位修复等手术治疗）和观察组（对照组手术治疗基础上,给予封闭式负压吸引、氧气、臭氧联合治疗）,每组各20例,对两组住院时间、肉芽组织覆盖创面时间,以及创面愈合情况进行观察和比较。结果与对照组比较,观察组住院时间、肉芽组织覆盖创面时间均显著缩短（P〈0.05）。两组创面愈合,死腔完全消除,没有出现明显并发症,创面细菌培养阴性。结论对于软组织缺损患者,手术治疗基础上,给予封闭式负压吸引、氧气、臭氧联合治疗,能够提高治疗的临床疗效。
