[Experience with osteosynthesis of the sternum after heart surgery in patients with limited physical abilities].

At the Department of Heart Surgery of the A. V. Vishnevsky Institute of Surgery in seven patients with limited physical abilities and having to ambulate on crutches for osteosynthesis of the sternum after cardiosurgical interventions we used Ti-Ni fixating cramps with self-regulating compression. This technique provided reliable fixation of the sternum even in the early postoperative period in patients with elevated loading on the shoulder gridle. On day 2-3 after the surgical intervention all patients began to observe the standard motor regimen, i.e., ambulation on crutches. The possibility of early activation in the initially severe cohort of patients with multifocal atherosclerosis and accompanying diseases was one of the factors of an uneventful course of the postoperative period and rapid rehabilitation. Neither sternal instability nor infectious complications during the in-hospital period were observed.

[Sternal osteosynthesis after cardiac surgery].

Sternal fixation with nickelide titanium staples with shape memory effect is considered to be a novel method of wound closure after cardiac operations. The study includes data of 140 patients and is devoted to the preliminary assessment of the use of the mentioned fixators with self-regulating compression. Osteosynthesis proved to be completely effective in 136 (97,1%) patients. The use of nitinol staples allows not only a secure sternal fixation with minimal risk of underlying structures' trauma, but decreases time of postoperative patients' rehabilitation after the major cardiac surgery.

[The epidemic situation of tick-borne encephalitis and Lyme disease in the city of Tomsk]. / Epidemicheskaia situatsiia po kleshchevomu éntsefalitu i bolezni Laima v g. Tomske.

Lyme disease and tick-borne encephalitis have similar principal epidemiological features chiefly associated with their basic carrier and determinants of human infection. The cases of Lyme disease, as evidenced by laboratory studies, indicate that there are active natural foci of this infection in the city, frequently combining with natural foci of tick-borne encephalitis. At the same time a great quantity of cases of tick-borne encephalitis and Lyme disease (mixed infection) is notified in Tomsk.

[Current approaches to the combination therapy of osteogenic sarcoma]. / Sovremennye podkhody k kompleksnoi terapii osteogennoi sarkomy.

The results of treatment of 315 cases of osteogenic sarcoma are presented. Available methods of primary tumor therapy fail to prevent dissemination of neoplastic disease by blood circulation. However, following a prophylactic course of chemotherapy (adriamycin, vincristine, cyclophosphamide, sarcolysine), 3- and 5-year survival rates in 45 cases of limb amputation for osteosarcoma increased to 38.1% and 30.5%, respectively. No recurrences were observed in 39 patients with extensive segmental resection of bone who preoperatively received intra-arterial infusions and radiation therapy; the 3-year survival rates were a high as 43.9% and patients showed good performance. The method offers good advantages in the treatment of patients with osteogenic sarcoma.

[Radioindication of bone graft healing]. / Radioindikatsiiia prizhivleniia kostnykh transplantatov.

To control the state of transplanted bone in different terms following the plastic procedure a radioisotope study by strontium-85 was performed in 29 patients. The results of scannography (in 31 cases) and radiometry (in 42 cases) were analysed. The determination of the character of strontium-85 distribution and the intensity of its accumulation in the operated extremity makes it possible to assess the graft condition and the intensity of osteogenesis a greater precision and earlier than does roentgenography. Radioisotope investigation conducted dynamically enable the prognostication of the course of the graft healing process.
