CT Appearance Following Partial Nephrectomy for Renal Cell Carcinoma Using Tissue Adhesive Bioglue

Open Journal of Urology 2013年第2期3卷 75-79页

Background: The use of biological sealants has greatly increased during nephron sparing surgery. In many cases the bulk of the material was erroneously mistaken for tumor recurrence. Objective: To describe the characteristic appearance of biological adhesive material used for tumor bed closure on computerized tomography (CT) following nephrone sparing surgery (NSS) for renal cell carcinoma, in order to differentiate between typical features of the adhesive material and local tumor recurrence. Design, Setting and Participants: We retrospectively reviewed follow-up CT scans of 120 patients who underwent NSS for T1N0M0 RCC. In all cases tumor bed was closed during surgery with biological tissue adhesive (BioGlue). Results and Limitations: During 1994-2009, 120 patients with a single T1 renal cell carcinoma lesion, underwent NSS with closure of tumor bed with bio adhesive material. There were 66 males and 47 females with mean age of 58.7 years (median: 58 years, range: 28 - 85 years). Mean follow-up time was 45 ± 34 months (median 42, range 12 - 168). During follow-up, 3 patients had local recurrence at the site of previous enucleated lesion. In the first post-operative CT scan the BG appeared as a heterogeneous mass with sharp edges measuring 20 - 70 HU with no attenuation following the injection of contrast material. In subsequent follow-up scans the BG in most patients remained stable in size;in few patients slight reduction in size was observed probably due to the resolution of post-operative hematoma. Tumor recurrence that was documented in 3 patients was seen as a heterogeneous mass with attenuation of more than 20 HU following the injection of contrast material. In sequential CT’s the mass was increasing in size. Conclusions: BG appears as a non-enhancing stable mass in sequential CT’s following NSS, hence could be differentiated from local tumor recurrence. The ability to differentiate between normal post-operative status and recurrence could be compromised in p

Intrahepatic CD8^+ lymphocyte trapping during tolerance induction using mushroom derived formulations:A possible role for liver in tolerance induction

引用

World Journal of Gastroenterology 2008年第24期14卷 3872-3878页

作者： Mony Shuvy Tiberiu Hershcovici Lidya Zolotarov Yaron Ilan Cristina LulI-Noguera Harry Wichers ofer Danay Dan Levanon Liver Unit Department of Medicine Hadassah HebrewUniversity Medical Center Jerusalem IL-91120 Israel WageningenUniversity and Research Center Wageningen 6706 KN TheNetherlands Migal Kiryat Shmone 11016Israel

AIM: To determine the immunomodulatory effect of Shiitake (a mushroom extract),we tested its effect on liver-mediated immune regulation in a model of immune-mediated colitis. METHODS: Four groups of mice were studied. Colitis was induced by intracolonic instillation of TNBS in groups A and B. Groups A and C were treated daily with Shiitake extract,while groups B and D received bovine serum albumin. Mice were evaluated for development of macroscopic and microscopic. The immune effects of Shiitake were determined by FACS analysis of intra-hepatic and intrasplenic lymphocytes and IFN-γ ELISPOT assay. RESULTS: Administration of Shiitake resulted in marked alleviation of colitis,manifested by signifi cant improvement in the macroscopic and microscopic scores,and by reduction in IFN-γ-producing colonies in group A,compared to group B mice (1.5 pfu/mL vs 3.7 pfu/mL,respectively). This beneficial effect was associated with a significant increase in the intra-hepatic CD8+ lymphocyte trapping,demonstratedby an increased intrasplenic/intrahepatic CD4/CD8 lymphocyte ratio. These effects were accompanied by a 17% increase in the number of intrahepatic natural killer T (NKT) cells. A similar effect was observed when Shiitake was administered to animals without disease induction. CONCLUSION: Shiitake extract affected liver-mediated immune regulation by altering the NKT lymphocyte distribution and increasing intrahepatic CD8+ T lymphocyte trapping,thereby leading to alleviation of immune-mediated colitis.

Enlarged and Colored Enhanced 3D Printing of Renal Artery Aneurysms for Improved Imaging and Treatment Planning

引用

World Journal of Cardiovascular Diseases 2016年第1期6卷 1-7页

作者： Aaron Hoffman Samy Nitecki Tony Karram Maxim Leiderman Igor Kogan Guennady Yudkovsky Amos ofer Department of Vascular Surgery and Transplantation and Department of Radiology Rambam Health Care Campus and Rappaport Faculty of Medicine Technion Haifa Israel

Three dimensional printing (3D printing) technology is increasingly used to improve results in many areas of medicine. Physical models produced by this technology allow better appreciation of complex anatomical and pathologic conditions. In cardiovascular medicine and surgery, 3D modeling has been reported to be of help in treatment planning of abdominal aortic aneurysm, especially in cases of complex angulations and branching at the aneurysm neck. Here we report the use of 3D printing in cases of renal aneurysms. Enhanced 3D models of CTA images of renal aneurysms were prepared in house using common and freely available software programs, and an accurate desktop 3D printer. Eight reconstructed models were enlarged by a factor of 2 or more and then differentially painted to delineate normal arteries and aneurysmatic ones. These enhanced 3D solid models allowed visual and tactile inspection for a better appreciation of complex aneurysms. Color enhancement of these models added another dimension of comprehension, even for experienced surgeons and invasive radiologists, and allowed more accurate measurements of branch numbers, distances, and angles in space even with severe tortuosity. Endovascular use of covered stents and embolization techniques could be easily envisioned preoperatively. We conclude that enhanced, enlarged, and colored 3D printed models are a powerful tool for preoperative endovascular treatment planning of complex renal artery aneurysms.

现代人起源于非洲,随后走出非洲占据了欧亚大陆和澳大利亚,这一过程发生在6万~4万年以前,同时欧洲和西亚的尼安德特人在这一期间消失。对于该事件发生的准确时间和原因,学术界并没有形成统一看法,因为在发掘和研究中仍存在一些尚待解决的问题。此外,在认识旧石器时代晚期革命性质、文化面貌以及现代人如何扩散到西亚和欧洲以外等问题都还不十分清楚,有待于以后找到更多与现代人多次扩散浪潮相关的考古资料。

2012—2103年在辽宁阜新地区查海遗址东部开展了区域性田野考古调查,调查范围104.46平方公里,共在1152个采集点进行了人工遗物的采集,发现了属于小河西、兴隆洼、赵宝沟、红山、夏家店下层、高台山、凌河类型和战国—汉时期的遗存,大体上勾勒出调查区域内从新石器时代早期,经青铜时代,一直到战国—汉时期的遗址分布格局。调查中确认了一些此前没有发现的早期新石器时代时期(也许还有前新石器时代)的遗址,而部分遗址人工遗物分布密度较高表现出当时人类活动已具有一定的强度。调查中还发现并记录了大量的细石器和一般石器,这是在此前中国东北地区系统性田野考古调查中从未做过的工作,这些石器的具体年代或文化属性还有待于进一步的比较与分析。如果有些石器的年代确实属于前新石器时代,那么这些石器的分布将会提供研究这一地区采集狩猎人群活动的重要证据。
