[The first clinical experience of using the new Senhance remote-controlled robotic system in general surgery in Russia].

Unlabelled: Until recently, clinical studies in the field of robotic-assisted surgery have been conducted in Russia only on the basis of the DaVinci system. The advent of a new robotic system separated the concept of «robotic surgery» from DaVinci. An increase in the number of alternative surgical robots will expand the possibilities of studying the functionality of these systems, differences in their operation, safety and efficiency for patients, and convenience for surgeons.

[Modern concepts on the pathogenesis of neuroborreliosis].

The analysis of publications on the websites PubMed, ClinicalKey, devoted to the pathogenesis of neuroborreliosis (NB), using keywords for search: «pathogenesis of neuroborreliosis», «neuroborreliosis in children», «pathogenesis of Lyme disease», as well as an analysis of the results of the published research results of the staff of the Research Institute of Pediatric Infections, St-Petersburg, Russia is presented. Syndromes of early and late NB are more often observed among the forms without migrating erythema, and their development can be caused by all representatives of the species (), but more often - , since it most effectively suppresses the factors of innate and adaptive immune response, reducing interferon production, phagocytosis and complement synthesis. The cause of immunosuppression with the development of NB may be simultaneous infection with several genovids and borrelia species or pathogens of other infections transmitted by Ixodes ticks, for example, infection with and tick-borne encephalitis virus.

[Spontaneous rupture of kidney tumor. Successful surgical treatment].

A clinical case of spontaneous rupture of the kidney lesion that occurred after physical exercise is presented in the article. During the examination (ultrasound, multi-slice computed tomography of the kidneys), the diagnosis was unclear, and therefore, the patient underwent surgical treatment. Given the risks of complications and impossibility to exclude the malignancy, a decision was made to perform nephrectomy.

[Operation in DeBakey type I acute aortic dissection according to the Florida Sleeve technique].

Despite the fact that recent decades have witnessed significant advances in treatment of patients with DeBakey type I acute aortic dissection, it still remains difficult to restore the aortic root when the dissection extends to the Valsalva's sinuses. Thinned aortic walls are vulnerable to traumatization on applying a vascular suture. We used in patients with this pathology the Florida sleeve technique in order to reinforce the weakened aortic root.
