1Through-needle all-optical ultrasound imaging in vivo: a preclinical swine study显示文摘High-frequency ultrasound imaging can provide exquisite visualizations of tissue to guide minimally invasive procedures.Here,we demonstrate that an all-optical ultrasound transducer,through which light guided by optical fibers is used to generate and receive ultrasound,is suitable for real-time invasive medical imaging in vivo.Broad-bandwidth ultrasound generation was achieved through the photoacoustic excitation of a multiwalled carbon nanotube-polydimethylsiloxane composite coating on the distal end of a 300-μm multi-mode optical fiber by a pulsed laser.The interrogation of a high-finesse Fabry–Pérot cavity on a single-mode optical fiber by a wavelength-tunable continuous-wave laser was applied for ultrasound reception.This transducer was integrated within a custom inner transseptal needle(diameter 1.08 mm;length 78 cm)that included a metallic septum to acoustically isolate the two optical fibers.The use of this needle within the beating heart of a pig provided unprecedented realtime views(50 Hz scan rate)of cardiac tissue(depth:2.5 cm;axial resolution:64μm)and revealed the critical anatomical structures required to safely perform a transseptal crossing:the right and left atrial walls,the right atrial appendage,and the limbus fossae ovalis.This new paradigm will allow ultrasound imaging to be integrated into a broad range of minimally invasive devices in different clinical contexts.Malcolm C Finlay Charles A Mosse Richard J Colchester Sacha Noimark Edward Z Zhang Sebastien Ourselin Paul C Beard Richard J Schilling Ivan P Parkin Ioannis Papakonstantinou Adrien E Desjardins 2017Light(Science & Applications)2017,6,1:6
2Reversion of severe hepatopulmonary syndrome in a non cirrhotic patient after corticosteroid treatment for granulomatous hepatitis:A case report and review of the literature显示文摘肝肺症候群(HPS ) 包括肺内的脉管的膨胀的肝疾病,反常肺的煤气的交换和证据被定义为一个临床的三个一组。我们报导在最后年与疲劳,长持续的发烧,体重减轻,门静脉高血压的符号,肝脾大,胆汁郁积和进步 dyspnoea 介绍的 61 岁的男性。临床,实验室和组织检查所见证实了肉芽肿肝炎的诊断。由于肝的导致 granuloma 的门静脉高血压的 HPS 被证明是由提高对比的回响心动描记法证实了的病人的严重血氧不足的原因。在皮质甾治疗以后的 HPS 的回复被新提高对比的回响心动描记法与胆汁郁积的酶的正规化和病人的条件的改进一起证实。这是在有肝的肉芽肿的一个非肝脏硬化症的病人的 HPS 的完全的回复的第一个案例,显示在肝疾病的那肺内分流是功能的现象, HPS 能甚至在象在这种情况中的其他的肝参与被开发。Nikolaos Tzovaras Aggelos Stefos Sarah P Georgiadou Nikolaos Gatselis Georgia Papadamou Eirini Rigopoulou Maria Ioannou Ioannis Skoularigis Georgios N Dalekos 2006World Journal of Gastroenterology2006,12,2:3
3Use of intercostal nerves for different target neurotization in brachial plexus reconstruction显示文摘Intercostal nerve transfer is a valuable procedure in devastating plexopathies. Intercostal nerves are a very good choice for elbow flexion or extension and shoulder abduction when the intraplexus donor nerves are not available. The best results are obtained in obstetric brachial plexus palsy patients, when direct nerve transfer is performed within six months from the injury. Unlike the adult posttraumatic patients after median and ulnar nerve neurotization with intercostal nerves, almost all obstetric brachial plexus palsy patients achieve protective sensation in the hand and some of them achieve active wrist and finger flexion. Use in combination with proper muscles, intercostal nerve transfer can yield adequate power to the paretic upper limb. Reinnervation of native muscles(i.e., latissimus dorsi) should always be sought as they can successfully be transferred later on for further functional restoration.Marios G Lykissas Ioannis P Kostas-Agnantis Ananstasios V Korompilias Marios D Vekris Alexandros E Beris 2013World Journal of Orthopedics2013,4,3:2

5Translation and validation of the Greek chronic liver disease questionnaire显示文摘AIM:To translate into Greek and validate the chronic liver disease questionnaire (CLDQ).METHODS:Two hundred and six consecutive adult patients with the diagnosis of a chronic liver disease from 2 general hospitals in Athens were enrolled in the study from May to September 2008.In order to assess their quality of life (QOL) the CLDQ was applied.The instrument was translated from English,back translated and reviewed in focus groups within the framework of a large multicenter study.The measurements that were performed included:2 independent sample t tests,oneway analysis of variance,reliability coefficients,explanatory factor analysis using a varimax rotation and the principal components method.RESULTS:One hundred and twenty five (61%) patients were men,half were aged 40-59 years and > 33% were > 60 years old.Among the patients,48 (23%) were hospitalized and 97 (47%) were cirrhotic according to the Child-Pugh score.The internal consistency of the Greek CLDQ version using Cronbach's alpha coefficient was found to be 0.93.Exploratory factor analysis identified 7 domains accounting for 65% of the variance of CLDQ items and only partially overlapping with those found in the original version.The area under the receiver operating characteristics curve was calculated at 0.813 and the logistic estimate for the threshold score of 167.50 provided a sensitivity of 74.3% and a specificity of 71.6% for the model.CONCLUSION:Our data confirmed the validity of the Greek version of the CLDQ in identifying the QOL among patients with chronic liver disease.Zoi Kollia Evridiki Patelarou Victoria Vivilaki Eleni Kollia Florentia Kefou Ioannis Elefsiniotis Spyros P Dourakis Hero Brokalaki 2010World Journal of Gastroenterology2010,16,46:2
