[Modern aspects of photo and laser therapy for wound infection in surgical practice].

The review is devoted to modern treatment technologies for wound infection. The majority of studies are devoted to pharmacological and surgical methods. A few reports describe non-drug methods including photo and laser therapy.

[Experimental studies of biodegradable ureteral stent prototype].

Degradable ureteral stent not requiring redo procedure for removal is an important issue in modern urology. This device could solve the problem of «forgotten stent» often leading to long-term complications. The authors describe the prototype of biodegradable ureteral stent based on poly(L-lactide-co-ε-caprolactone) and present the first results of its testing.

[Experimental substantiation of medical device design for mechanical processing of adipose tissue].

Objective: To substantiate the medical device design for mechanical processing of adipose tissue.

Material And Methods: Enzymatic method using collagenase and mechanical method for obtaining the stromal vascular fraction (SVF) are compared. The authors emphasized the disadvantages of enzymatic method, such as high cost and duration of process.

[Immediate outcomes of simultaneous Cox-Maze procedure in patients with isolated and multivalvular heart defects via right mini-thoracotomy].

Objective: To evaluate the immediate outcomes and safety of simultaneous Maze procedure in patients with isolated and multivalvular heart disease via right-sided mini-thoracotomy.

Material And Methods: A retrospective analysis of postoperative outcomes included 21 patients with various valvular heart diseases and atrial septal defects with atrial fibrillation. All patients underwent heart valve surgery with cryoablation (left atrial, right atrial or biatrial «Maze» approach) via right-sided mini-thoracotomy.

Long-Term Structural Changes in the Osteochondral Unit in Patients with Osteoarthritis Undergoing Corrective Osteotomy with Platelet-Rich Plasma or Stromal Vascular Fraction Post-Treatment.

This pilot study examined the long-term structural changes in the osteochondral unit of 20 patients with knee osteoarthritis (KOA) who underwent high tibial osteotomy (HTO) and received post-treatment with either platelet-rich plasma (PRP) or stromal vascular fraction (SVF). Ten patients were injected with autologous PRP (PRP subgroup), while another ten patients received autologous SVF (SVF subgroup) six weeks after surgery and were monitored for 18 months. Histological samples of bone and cartilage (2 mm in diameter and 2 cm long) were taken from tibial and femoral sites during surgery and 18-month post-HTO, and morphometric analyses were conducted using Mega-Morf12 software.
