Conservative Treatment in Avascular Necrosis of the Femoral Head: A Systematic Review.

Introduction: Avascular necrosis (AVN) of the femoral head is a pressing orthopedic issue, leading to bone tissue death due to disrupted blood supply and affecting the quality of life of individuals significantly. This review focuses on conservative treatments, evaluating their efficacy as mainstay therapies. Enhanced understanding of AVN's pathophysiology and advancements in diagnostic tools have rekindled interest in non-surgical interventions, emphasizing personalized, multidisciplinary approaches for improved outcomes.

Isolated liver chemo perfusion for hepatic metastases from uveal melanoma: a report of 38 cases.

Aim: To evaluate the outcomes of isolated liver chemo perfusion in patients with hepatic metastases from uveal melanoma.

Materials And Methods: Cardiovascular surgeons are often involved in the treatment of oncological diseases. Isolated liver chemoperfusion requires the use a heart-lung machine.

Results of carotid endarterectomy with the use of temporary shunts with reduced retrograde pressure in the internal carotid artery - analysis of the multicenter Russian register.

Aim: The aim of the study was to assess the role of a temporary carotid shunt in patients undergoing carotid endarterectomy.

Materials And Methods: This was a retrospective, multicentric ( = 159) study carried out between January 2005 and October 2020. The study included 3114 patients undergoing carotid endarterectomy who had a reduced retrograde internal carotid artery pressure (<60% of systolic blood pressure).

Inflammation Control and Immunotherapeutic Strategies in Comprehensive Cancer Treatment.

Tumor growth and expansion are determined by the immunological tumor microenvironment (TME). Typically, early tumorigenic stages are characterized by the immune system not responding or weakly responding to the tumor. However, subsequent tumorigenic stages witness the tumor promoting its growth and metastasis by stimulating tumor-protective (pro-tumor) inflammation to suppress anti-tumor immune responses.

A non-randomized comparative study of olfactory and gustatory functions in children who recovered from COVID-19 (1-year follow-up).

The experimental group included 68 children over 6 years of age who had recovered from COVID-19. The control group included 22 children over 6 years of age who have never had COVID-19. Research methods included neurological examination, verification of cognitive status, examination by an otolaryngologist, and smell and taste assessment.

[Ocular iontophoresis].

Iontophoresis in medicine is a combined pharmacological and physical method of treatment that unites the therapeutic effect of an electric current with the pharmacological effect of medicinal substances administered at the same time via an electric current. The article describes the physical basis of the therapeutic effect of direct electric current on biological tissues, and highlights the physical and chemical mechanisms of target administration of pharmaceutical substances into the human body through intact skin or mucous membrane by means of direct electric current. In addition, it presents the results of international as well as Russian domestic scientific studies on the clinical effectiveness of iontophoresis in ophthalmology.

[The use of vascularized scrotal and penile flaps in reconstructive surgery of the urogenital region].

The aim of the work is to present a modern view on the clinical application of urogenital flaps, such as autologous scrotal flap and foreskin. This plastic material has such characteristics as acceptable extensibility, good blood supply, accessibility and the absence of significant defects in the donor area. The use of urogenital flaps is an actual and promising direction in reconstructive urology.

[Laparoscopic partial nephrectomy using a technology of augmented reality: new vector of the development of operative urology?].

Aim: to evaluate the efficiency and usefulness of augmented reality (AR) technology using HoloLens glasses for laparoscopic partial nephrectomy (LPN).

Materials And Methods: From July to December 2019, a total of 5 patients with localized kidney cancer (cT1aN0M0) underwent AR-assisted LRP. The mean RENAL score was 6 points (5-8).
