    Craniopharyngioma is a benign tumor of the brain, developing from the epithelial cells of craniopharyngeal duct, from which are formed abiogenetically the stem and rear part of the pituitary gland. The peculiarity of stem craniopharyngiomas is dense accretion of the tumor with arterial and neural structures of supra-para-retrosellar area, which makes surgical treatment technically difficult, and sometimes — obviously impossible. In the world literature at this point does not contain messages about the isolated stem radiosurgical treatment of craniopharyngiomas with application installations, Gamma knife or CyberKnife. A clinical case of stereotactic radiosurgical treatment in the mode of hypofractionation on the Leksell Gamma Knife Perfexion apparatus with a positive result in the form of a significant regression of visual disturbances is presented. Index terms: stereotactic radiosurgery, hypofractionation, craniopharyngioma, sellar region.Краниофарингиома — это доброкачественное новообразование головного мозга, развивающееся из эпителиальных клеток краниофарингиального протока, из  которого эмбриогенетически образуются стебель и  задняя часть гипофиза. Особенностью стебельных краниофарингиом является плотное срастание опухоли с артериальными и  невральными структурами супра-пара-ретроселлярной области, что делает хирургическое лечение технически сложной задачей, а иногда — заведомо невыполнимой. В мировой литературе на данный момент не содержится сообщений об изолированном радиохирургическом лечении стебельных краниофарингиом с применением установок Гамма-нож или КиберНож. Представлен клинический случай стереотаксического радиохирургического лечения в режиме гипофракционирования на аппарате Leksell Gamma Knife Perfexion с положительным результатом в виде значительного регресса зрительных нарушений

    Purpose. To assess the additional contribution of SPECT/CT, used in conjunction with planar osteoscintigraphy, in bone metastatic disease detection and its effect on the tactics of managing patients with breast cancer and prostate cancer. Materials and methods. The study included 1412 patients with established oncological diagnosis (breast cancer — 844 patients, prostate cancer — 568 patients), to which «whole body» planar osteoscintigraphy, and SPECT/CT were performed. In all patients included in the study, the fact of bone metastatic disease was established by the results of additional imaging techniques and follow up. Results. Bone metastatic disease was detected in 324 (23%) patients and excluded in 1088 (77%). SPECT/CT had higher diagnostic indices than planar osteoscintigraphy. Sensitivity, specificity and accuracy of bone metastatic disease detection of planar osteoscintigraphy were 91%, 71%, 76%, of SPECT/CT, 97%, 93%, 94%, respectively. The additional use of SPECT/CT in the second stage after the planar osteoscintigraphy in 337 (24%) patients from the general group (n=1412) led to a change in the results of the diagnostic test. Conclusions. The additional use of SPECT / CT in the second stage after the planar osteoscintigraphy allows to change the results of the diagnostic test in the evaluation of bone metastatic disease in patients with breast cancer and PCa, which can significantly affect the management tactics of patients

    The purpose of the study was to assess the function of fibres of the left ventricle (LV) and its dynamics after revascularization in patients with non Q myocardial infarction using standard Echocardiography (EchoCG) and Velocity Vector Imaging (VVI). Materials and methods: 34 patients with MI were examined. Echocardiography studies were performed on the ultrasound scanner AcusonX 300 (Siemens), a 1–5 MHz transducer before and in early period after coronary artery bypass grafting (CABG). Results. Standard EchoCG showed systolic LV dysfunction before and after CABG, contractile dysfunction in 51 (8%) segment before the operation, with subsequent recovery of the function of the 28 (54%) of them. The effect of MI on LV function using VVI showed reducing strain (S) and normal strain rate (SR) of the longitudinal fibers, decrease S and SR of circular fibers and normal function of radial fibers. After GABG S and SR of longitudinal fibers has not changed, S and SR of the circular fibres are decreased. The function of radial fibers are normal. The study established a relationship between the level of LDH-1 and SR of the circular fibers of the LV prior to CABG. Increased level of LDH-1 in the early period after CABG can be a predictor of reduction of S and SR circular fibers. Conclusion: In patients with it is necessary to analyze not only the longitudinal and radial fibers, but also circular

    The article deals with the results of radiological and clinical laboratory testing of 108 victims treated in «St. Petersburg research Institute of emergency care named after I. I. Dzhanelidze», in the period from 2015 to 2017, with associated trauma of the spine. The patients developed suppurative-inflammatory diseases and their complications. CT diagnosis of purulent-inflammatory diseases of the spine combined injury. In addition, the article presents literature data about the use of radiologic methods of examination (x-ray, computed tomography, magnetic resonance imaging) purulent-inflammatory diseases of the spine and their complications.В статье представлены результаты лучевого и клинико-лабораторного обследования 108 пострадавших, находившихся на  лечении в  «Санкт-Петербургском научно-исследовательском институте скорой помощи им. И. И. Джанелидзе», в период с 2015 по 2017 г., с сочетанной травмой позвоночника. Рассмотрены случаи развившихся у  пострадавших гнойно-воспалительных заболеваний и  их осложнения. Изучены возможности КТ-диагностики гнойно-воспалительных заболеваний позвоночника при сочетанной травме. Кроме того, в статье представлены данные литературных источников о применении методов лучевого обследования (рентгеновское исследование, компьютерная томография, магнитно-резонансная томография) при гнойно-воспалительных заболеваниях позвоночника и их осложнениях
