[Percutaneous cholecystostomy in multi-field hospital].

Objective: To analyze the indications, technical features and results of percutaneous cholecystostomy.

Material And Methods: A retrospective single-center study of the results of percutaneous cholecystostomy over 13-year period was carried out. The indications for surgery, technical features and outcomes were studied.

[Technologies for early diagnosis of oral mucosal diseases].

Objective: Expert evaluation of minimally invasive techniques in the diagnostic algorithm of pathological processes of the oral mucosa.

Material And Methods: Fluorescence stomatoscopy of the oral mucosa of 1520 patients aged 18-65 years with analysis of color code of optical images was carried out. The nature of the disease was established by liquid cytology.

Activated carbon additives for technetium immobilization in bentonite-based engineered barriers for radioactive waste repositories.

Safe disposal of nuclear waste in a geologic repository will rely on natural geologic features and engineered barriers to greatly retard the movement of radionuclides from the repository. Clay minerals including bentonite are effective in retarding the migration of many radionuclides, but are ineffective for anionic radionuclides, of which pertechnetate is of particular concern owing to its relatively long half-life and the lack of natural isotopes that dilute it. Activated carbon is proposed as an additive material for reducing pertechnetate mobility in the nearfield.

[Analysis of the causes of recurrent postoperative ventral hernias].

Objective: To study the causes of recurrent postoperative ventral hernias and methods for their prevention.

Material And Methods: There were 58 patients with recurrent postoperative ventral hernias after various methods of abdominal wall repair for the period 2005-2017.

Results: The main causes of recurrent postoperative ventral hernias were identified.

[Oral diseases structure in patients with diffuse liver lesions before and after transplantation].

Unlabelled: Purpose of the study was to identify dental risk factors for complications at the stage of rehabilitation adaptation in patients with diffuse liver lesions. The study included 52 patients with diffuse liver lesions aged 25-55 years, who were divided between two groups of 26 persons with different dental status, depending on the main disease stage of treatment.

Research Methods: Clinical, x-ray, morphological, analytical, statistical.
