Endoscopic Surgery in Trachea and Bronchi

Эндоскопические операции (ЭО) прочно вошли в арсенал торакальной хирургии как метод паллиативного лечения рака легкого и малоинвазивного радикального лечения ряда доброкачественных заболеваний трахеи и крупных бронхов. Среди различных методик ЭО наибольшее распространение получили методы лазерной и электрохирургической реканализации дыхательных путей. Накопленный в клинике 25-летний опыт ЭО при ряде заболеваний трахеобронхиального дерева позволил поделиться им в настоящем сообщении.Experience in 1623 endoscopic operations in 976 patients with tumors and cicatricle stenosis of trachea and bronchi has been carried out. The results of endoscopic operations with the use of AIG-laser rays and electrosurgical methods have been analyzed. Improvement in the bronchial passage was achieved in 85% of the patients. Complications were seen in 3% of cases, death was registered in 15 (1.5%) during the process of treatment. In case of tumorous stenosis, endoscopic recanalization brought rough palliative character enhanced the quality of daily life

Search for a correlation between the UHECRs measured by the Pierre Auger Observatory and the Telescope Array and the neutrino candidate events from IceCube

We have conducted three searches for correlations between ultra-high energy cosmic rays detected by the Telescope Array and the Pierre Auger Observatory, and high-energy neutrino candidate events from IceCube. Two cross-correlation analyses with UHECRs are done: one with 39 cascades from the IceCube ‘high-energy starting events’ sample and the other with 16 high-energy ‘track events’. The angular separation between the arrival directions of neutrinos and UHECRs is scanned over. The same events are also used in a separate search using a maximum likelihood approach, after the neutrino arrival directions are stacked. To estimate the significance we assume UHECR magnetic deflections to be inversely proportional to their energy, with values 3◦ , 6◦ and 9 ◦ at 100 EeV to allow for the uncertainties on the magnetic field strength and UHECR charge. A similar analysis is performed on stacked UHECR arrival directions and the IceCube sample of through-going muon track events which were optimized for neutrino point-source searches. </p
