The xenon, argon, neodymium:YAG and dye lasers have been successfully used in out-patient clinics. The excimer laser has been attracting researchers' interest in the new application of laser to cornea and lens. The erbium:YAG laser emits a 2.94-microns beam that can ablate the transparent ocular tissues such as lenses and corneas. The author has applied this laser to the cornea, lens, vitreous and other ocular tissues. The erbium:YAG laser beam was directed through a 1.5-meter-long, 200-microns-diameter fiberoptic guide. The radiant energy measured about 50 mJ at the end of the probe. The laser was emitted as a 400-microsecond pulse. Freshly enucleated rabbit eyes were used in this study. Laser burns were applied to the tissue surface at various energy settings. At minimal power, the tissues were coagulated by the erbium:YAG laser application. At a power of more than 636-954 mJ/mm2, tissue began to evaporate; the tissue loss was observed under a surgical light microscope. Corneal photoablation, lens ablation, iridotomy, trabeculotomy, cutting of the vitreous and retinal ablation were easily performed. Like the excimer laser, the erbium:YAG laser is a potential tool for ocular surgery.}, subject = {Augenchirurgie}, language = {en} } @article{ChaloupkaRaptisZachetal., author = {Chaloupka, I. and Raptis, Georgios and Zach, A. and Br{\"a}ndlin, K. and Meier-Ewert, H.}, title = {Rolle der quantitativen CMV-DNA-Bestimmungen in der Diagnostik und Therapie der Cytomegalovirusinfektion bei immunsupprimierten Patienten}, series = {Jahrestagung der Gesellschaft f{\"u}r Virologie in Wien, April 2000}, journal = {Jahrestagung der Gesellschaft f{\"u}r Virologie in Wien, April 2000}, subject = {Cytomegalie-Virus}, language = {de} } @article{HornPippigRaptisetal., author = {Horn, Lars-Christian and Pippig, S. and Raptis, Georgios and Fischer, Uta and K{\"o}hler, U. and Hentschel, Bettina and Martin, Rosemarie}, title = {Clinical relevance of urokinase-type plasminogen activator and its inhibitor type-1 (PAI-1) in squamous cell carcinoma of the uterine cervix}, series = {Australian and New Zealand Journal of Obstetrics and Gynaecology}, volume = {42}, journal = {Australian and New Zealand Journal of Obstetrics and Gynaecology}, number = {4}, doi = {10.1111/j.0004-8666.2002.00385.x}, pages = {385 -- 388}, abstract = {Objective The expression of uPA and PAI-1 as parameters of tumour-associated proteolysis has been implicated in the process of tumour cell invasion and the metastatic process. However, there is limited information on the impact of these parameters in cervical carcinoma. Methods Quantitative levels for uPA (n = 114) and PAI-1 (n = 103) were researched in operatively treated, surgically staged squamous cell cancer of the uterine cervix, using an ELISA-technique. Results were assessed regarding their impact in predicting pelvic lymph nodes metastases, tumour recurrence rate and recurrence free survival (RFS) using uni- and multivariate analysis. Results Median levels of both parameters were significantly higher in tumour tissue than in normal cervical tissue (p < 0.001). Detection of uPA gave no useful prognostic information. PAI-1 concentration showed a positive correlation with advanced tumour stage (p = 0.008), but no significant correlation with nodal status (pN0: 2.6 vs. pN1: 4.0 ng/mg protein; p = 0.092). Using a cut-off level of 2.4 ng/mg protein, patients with elevated PAI-1 levels demonstrated reduced RFS (45.9 versus 52.9 months; p = 0.1). Multivariate analysis, including nodal status, tumour stage, lymphovascular space involvement and grading failed to demonstrate any prognostic impact of uPA and PAI-1. Conclusions The results indicate, that PAI-1 expression is of some prognostic impact in cervical cancer, indicating an association of elevated PAI levels with local tumour progression and reduced recurrence-free survival.}, subject = {Plasminogen human-Aktivator}, language = {en} } @article{FischerRaptisGessneretal., author = {Fischer, Uta and Raptis, Georgios and Geßner, W. and Roschlau, U. and Dressel, K. and Bilek, Karin and Horn, Lars-Christian}, title = {Epidemiologie und formale Pathogenese des Zervixkarzinoms}, series = {Zentralblatt f{\"u}r Gyn{\"a}kologie}, volume = {123}, journal = {Zentralblatt f{\"u}r Gyn{\"a}kologie}, number = {4}, pages = {198 -- 205}, subject = {Geb{\"a}rmutterhalskrebs}, language = {de} } @article{HornFischerHaneletal., author = {Horn, Lars-Christian and Fischer, Uta and Hanel, C. and Kuhn, H. and Raptis, Georgios and Bilek, Karin}, title = {p53 in surgically treated and pathologically staged cervical cancer}, series = {Pathology - Research and Practice}, volume = {197}, journal = {Pathology - Research and Practice}, number = {9}, pages = {605 -- 609}, subject = {Geb{\"a}rmutterhalskrebs}, language = {en} } @article{HornRaptisFischeretal., author = {Horn, Lars-Christian and Raptis, Georgios and Fischer, Uta and Bilek, Karin}, title = {Impact of tumorload in surgically treated, histologically staged early cervical cancer: Multivariate analysis of 568 patients}, series = {International Journal of Gynecology \& Obstetrics}, volume = {70}, journal = {International Journal of Gynecology \& Obstetrics}, number = {Suppl. 1}, pages = {20 -- 21}, subject = {Geb{\"a}rmutterhalskrebs}, language = {en} } @article{HornRaptisFischeretal., author = {Horn, Lars-Christian and Raptis, Georgios and Fischer, Uta and Bilek, Karin}, title = {p53-tumorsuppressor gene in surgically treated histologically staged early cervical cancer}, series = {International Journal of Gynecology \& Obstetrics}, volume = {70}, journal = {International Journal of Gynecology \& Obstetrics}, number = {Suppl. 1}, pages = {112}, subject = {Tumorsuppressor-Gen}, language = {en} } @article{HornRaptisMartin, author = {Horn, Lars-Christian and Raptis, Georgios and Martin, Rosemarie}, title = {Tumorassoziierte Proteolyse, p53-Immunhistochemie und Zelladh{\"a}sion bei prim{\"a}r operierten Zervixkarzinomen}, series = {Geburtshilfe und Frauenheilkunde}, volume = {60}, journal = {Geburtshilfe und Frauenheilkunde}, number = {Suppl. 1}, pages = {200}, subject = {Tumorassoziierte Proteolyse}, language = {de} } @article{HornRaptisFischeretal., author = {Horn, Lars-Christian and Raptis, Georgios and Fischer, Uta and Bilek, Karin}, title = {Standardised handling of hysterectomy specimen in cervical cancer - report of over 900 stage pT1b1- to pT2b-tumors}, series = {Pathology - Research and Practice}, volume = {196}, journal = {Pathology - Research and Practice}, pages = {450}, subject = {Geb{\"a}rmutterhalskrebs}, language = {en} }
