Journal ArticleDOI
Photodynamic ablation of high-grade dysplasia and early cancer in Barrett's esophagus by means of 5-aminolevulinic acid
Liebwin Gossner,Manfred Stolte,Ronald Sroka,K. Rick,Andrea May,Eckhard Gerhard Hahn,Christian Ell +6 more
TL;DR: Testing 5-aminolevulinic acid (5-ALA)-induced protoporphyrin IX, a photosensitizer with a high mucosa specificity without phototoxic side effects on the skin, as a new form of PDT found it to offer a minimally invasive treatment modality as an alternative to esophagectomy.

Journal ArticleDOI
Pharmacokinetics of 5-aminolevulinic acid-induced protoporphyrin IX in skin and blood
K. Rick,Ronald Sroka,Herbert Stepp,Martin Kriegmair,Rudolf M. Huber,K. Jacob,Reinhold Baumgartner +6 more
TL;DR: The results of this experiments suggest that for a systemic application of 5-ALA side-effects in sensitive patients cannot be excluded, and PPIX levels in the plasma of blood samples could be detected via its fluorescence for all studied routes of application with the exception of the ointment.
Journal ArticleDOI
Investigation on radiofrequency and laser (980 nm) effects after endoluminal treatment of saphenous vein insufficiency in an ex-vivo model.
Claus-Georg Schmedt,Ronald Sroka,Stephanie Steckmeier,Oliver Meissner,Gregor Babaryka,Kathrin Hunger,Volker Ruppert,Mojtaba Sadeghi-Azandaryani,Bernd Steckmeier +8 more
TL;DR: Results and theoretical considerations indicate that endovenous laser treatment should be modified in order to ensure controlled homogenous circular thermal damage, avoiding vessel wall perforation and damage to perivascular structures.
Journal ArticleDOI
Laser treatment of hyperplastic inferior nasal turbinates: A review
TL;DR: A comparative review of the literature was performed to determine the value of laser treatment of hyperplastic inferior nasal turbinates.
