Rationale. Acneiform (papulopustular) rash is the leading dermatological adverse event of EGFR inhibitors. The development of optimal regimens for the supportive treatment of acneiform rash remains an important interdisciplinary problem in supportive oncology. Aims — to comparatively evaluate the clinical efficacy of the supportive treatment for acneiform rash induced by epidermal growth factor receptor inhibitors, including topical treatment with ivermectin cream and balneotherapy. Methods. In an open, prospective, randomized study, data from 114 patients with acneiform rash induced by monoclonal antibodies to EGFR were analyzed. All groups received intermittent supportive treatment according to a single regimen, continuous external therapy included: in group 1 — hypotonic thermal water, in group 2 — ivermectin 1% cream, in group 3 — hypotonic thermal water and ivermectin 1% cream. The observation period was 3 months. Acneiform rash severity was assessed using the CTCAE-NCI v5.0 criteria and a developed acneiform rash clinical severity scale. The intensity of subjective symptoms was assessed using a 10-point visual analog scale (VAS). The modified dermatological life quality index (mDLQI) was used to assess the impact of acneiform rash on patient’s quality of life. Results. A significant decrease in all of the studied parameters was observed in the groups by the end of the 1st week of supportive treatment and remained up to the end of the observation period (p < 0.05). There were no statistically significant differences between groups 2 and 3 with respect to the acneiform rash clinical severity scale, but their values were significantly lower than those of group 1 (group 1 vs. group 2, p < 0.001; group 1 vs. group 3, p < 0.001). The most rapid resolution of all subjective symptoms was observed in group 3. Significantly lower mDLQI values were also observed in group 3 starting from the 1st week of supportive treatment until the end of the follow-up period (р < 0.05). No severe adverse reactions were registered in any of the groups during the study. Conclusions. The developed regimens for the supportive treatment of acneiform rash have demonstrated a high efficacy in resolving papulopustular rash and associated subjective symptoms. The use of a complex approach including continuous topical therapy with ivermectin cream and hypotonic thermal water leads to the resolution of rash and relief of subjective symptoms in the shortest time, allows to safely maintain the achieved clinical effect for a long period of observation, has the most significant positive impact on the quality of life of cancer patients.

For more than 60-year history of coronary artery bypass grafting, surgical techniques and specialists’ competence were improved as well as the safety of anesthesiological management. This analytical review discusses modern features of analgesia during coronary surgery and early postoperative period. We described current opinion on perioperative administration of opioids and modern methods of analgesia, taking into account possible complications of their use. Despite the low mortality and overall safety of coronary bypass grafting nowadays, the optimal strategy of analgesia for this surgery is not established yet. This review lists routinely used analgetics and some aspects of their use in cardiac anesthesiology, outlines trends and prospects for the introduction of new drugs and techniques for analgesia. Despite a number of restrictions on the use of opioids in intensive care in modern era, in cardiac anesthesiology their use remains justified and, under certain conditions, safe enough.

Background. According to Russian epidemiological studies, the prevalence of chronic heart failure (CHF) in the general population is high and amounts to 7–10%. Therapy of any disease, and especially chronic disease, is associated with the prescription of drugs. With the development of evidence-based medicine and implementation of its achievements in real clinical practice all over the world there is an increase in the number of prescribed drugs. This explains the high relevance of the problem of drug-drug interactions. Aims — analysis of interactions of drugs recommended for prescription to patients suffering from CHF. Methods. Based on the Clinical Guidelines (CG), all possible interdrug interactions of recommended medicinal products were analysed. Information on potential drug-drug interactions was obtained from the specialised website Drugs.com. Know more. Be sure (https://www.drugs.com/interactions/list/). Results. ACE inhibitors / ARA II / valsartan+sacubitril, beta-adrenoblockers and aldosterone antagonists are recommended as part of combination therapy for treatment according to CG for all patients with symptomatic heart failure (class II–IV) and reduced LV ejection fraction < 40%. Amiodarone, verapamil and diltiazem are among the drugs not recommended for use in patients with the diagnosis of CHF. Also, according to clinical guidelines, HMG-CoA reductase inhibitors (atorvastatin, lovastatin, pitavastatin, rosuvastatin, simvastatin, fluvastatin), direct renin inhibitors (heparin), COX-2 inhibitors (parecoxib, polmacoxib, celecoxib, etoricoxib) are among the unrecommended drugs in chronic heart failure.For ACE inhibitors, no adverse effects from interaction with beta-blockers have been identified. This combination is widely used and recommended by the CG. According to the “Major” type for ACE inhibitors with drugs indicated for use in CHF according to CG, 4 potential interactions were identified: with valsartan-sacubitril; angiotensin II receptor antagonists; with aldosterone antagonist (spironolactone); with loop and thiazide diuretics. Therefore, the appointment of angiotensin II receptor antagonists is carried out in case of ineffectiveness of initial therapy with ACE inhibitors, when changing the treatment tactics. These drugs are not used in combination with each other due to the risk of hyperkalemia. The prescription and use of diuretics while taking ACE inhibitors should be controlled by a physician also due to the risk of hyperglycaemia. In Moderate type, potential interactions with dapagliflozin, eplerenone, cardiac glycosides and heparin have been identified for ACE inhibitors. For beta-blockers, no potential Major-type interactions were identified with drugs from CG. Combinations with dapagliflozin, loop and thiazide diuretics, cardiac glycosides, spironolactone and ivabradine require special attention. It is recommended to avoid the combination of beta-blockers with valsartan. Of the recommended angiotensin II receptor antagonists, no risk of potential interactions with beta-blockers has been identified for candesartan and losartan.

Malignant neoplasms of the bladder with invasion into the muscle layer of the organ wall (MIBC) are recognized as a highly aggressive pathology with a poorly predicted outcome, a high mortality rate, involving patients of any age without gender differences. Radical surgery’s in patients with MIBC has long and highly established itself as one of the main methods of treatment. However, the results of open surgical interventions are still accompanied by a high level of complications. The materials of medical literature (PubMed, CrossRef) for 2000–2023 were studied, with the issues of comparative evaluation of the results of surgical treatment of patients with MIBC, complications of the postoperative period. The search was conducted on the key phrases “bladder cancer”, “open cystectomy”, “robot-assisted cystectomy”, “cancer-specific survival”. The widespread introduction of video-endoscopic methods of treating patients with this disease into clinical practice has made it possible to speak about a decrease in the volume of intraoperative blood loss, the frequency of infectious complications of the wound and inpatient stay. The development of robot-assisted bladder surgery (RARC) demonstrates a number of advantages of using the daVinci robot in terms of reducing the number of postoperative complications during the traditional to study the 30–60–90-day follow-up periods. The issues of rehabilitation of patients after various methods of urine diversion, the medical-economic aspects for RARC in expert urological centers and the feasibility of the widespread introduction of this technique in medical institutions remain unclear. The coverage of these issues in the medical scientific literature is ambiguous, and therefore requires additional analysis.

Background. The peculiarities of the economic and geographical position of the Far Eastern Federal District determine climatic, socio-biological and medical and organizational characteristics that affect the leading criteria for population health. A relevant and priority direction for the development of the macro-region is the study of the main indicators of population health, reflecting the organizational and economic potential of the region, as well as the preservation and promotion of public health based on the formation of a healthy lifestyle and increasing the availability and quality of medical care. Aims — study and analyse the primary morbidity of the adult population in the Far Eastern Federal District. Methods. A retrospective analytical study was carried out. An analysis of the dynamics of primary morbidity by rate of increase (decrease) and a comparative analysis of average annual primary morbidity, including major classes of diseases diagnosed for the first time in life, in the adult population in the macro-region as a whole and in its 11 constituent entities is given. I–IV, VI–XIV, XVII, XIX classes of diseases were taken into account according to the International Classification of Diseases of the 10th revision. Results. The Far Eastern Federal District ranked 5th in descending order by primary morbidity among other Russian macroregions throughout the study period. There was variability in the primary morbidity ranking among the constituent entities of the district. The dynamics of primary morbidity showed a moderate upward trend in 2017, followed by two years of stable trend, and in 2020 there was a moderate downward trend. The prevalence of disease in patients diagnosed for the first time in the population of the other federal districts of the country was characterised by individual variability. At the same time, in most macro-regions a moderate to pronounced decrease in primary morbidity was found in 2020 (rate of increase (decrease) morbidity: from –2.3 to –7.2%), except for the Central Federal District (rate of increase (decrease) morbidity: –0.1%) and the Urals Federal District (rate of increase (decrease) morbidity: –0.2%), where this indicator remained stable. Conclusions. In the Far Eastern Federal District, characteristic variability in the level, dynamics and structure of primary morbidity among the population has been identified. A general pattern with all-Russian indicators was revealed, consisting in a decrease in incidence in most classes of diseases in 2020, except for X Respiratory disease, in which stability remained. The revealed features of the rank distribution of primary morbidity by classes of diseases in the subjects of the district will make it possible to be based on the principle of targeted distribution of funds when planning the volume of medical care to the population.

Psoriasis (PsO) and atopic dermatitis (AD have much in common: both diseases are widespread, characterized by a chronic relapsing course, primarily affect the skin and lead to a quality reduction of life of patients, regardless of their age. The pathogenesis of these two dermatoses, which are the most common in the practice of a pediatric dermatologist, is quite different. PsO is a chronic inflammatory skin disease, the pathogenesis of which is associated with the involvement of the Th1 pathway: Th17 cells and the IL-23/IL-17 axis. AD, in turn, is usually associated with high levels of IL-4, IL-5, IL-13, IL-31 and IFN-γ produced by activated T-helper 2 (Th2) cells. The clinical symptoms and immunopathological responses of these two skin conditions tend to differ. However, patients with PsO may sometimes present with a skin rash resembling AD combined with intense itching and laboratory increase in immunoglobulin E (IgE) which may indicate the need to change the paradigm of dominance of only one type of T-inflammation in patients with these diseases.

Periprosthetic joint infection is the main social and economic problem of modern orthopedics with a recurrence rate of chronic forms of up to 23.2–31.5%. The aim of this review is to inform various specialties doctors about the features of pathogenesis, etiology and treatment of periprosthetic joint infection, which significantly differ it from of other surgical site infections. The severity of infectious complications is due to the suppression of the patient’s immune system and microbial biofilms. Surgical treatment of periprosthetic joint infection involves debridement with preservation or removal of the implants, resection arthroplasty and arthrodesis. Today, in the treatment of more than 80% of cases of chronic infection, a two-stage approach is used, which allows to restore joint function after an average of 1.0–1.5 years. An integral part of the treatment of patients is high-dose, long-term and combined antibiotic therapy, which allows you to effectively deal with the leading pathogens of periprosthetic infection Staphylococcus aureus and S. epidermidis, the share of which is 46.5–57.5%. In the conditions of growing resistance of bacteria to antibiotics, the interest of researchers in the possibilities of using bacteriophages in the complex therapy of infections of bones and joints has increased. The cost of treatment exceeds the cost of “aseptic” joint replacement by 2–24 times and is characterized by a high level of disability and mortality of patients. Taking into account the numerous factors affecting the course and effectiveness of complex treatment of patients with periprosthetic infection, a multidisciplinary approach is currently considered the main component of success. The medical and social significance and high financial costs of treating patients with periprosthetic infection indicate the need for further research and the active implementation of effective scientific developments in the practical healthcare system.

The widespread occurrence of drug-resistant tuberculosis is an important public health challenge. To better understand this phenomenon, the article summarizes current ideas on the development of mechanisms of Mycobacterium tuberculosis resistance to antituberculosis drugs. Special attention is paid to the mechanism of acquired resistance based on mutations in the genes encoding antituberculosis drug targets or enzymes that translate pro-drug into its active form; the effect of these mutations on fitness of the pathogen is in the focus of the article. It emphasizes the leading role of molecular genetic methods for diagnosing M. tuberculosis drug resistance and importance of these methods for preventing the expansion of the pathogen’s resistance range and the spread of resistant clones in the population. A comparison of sequencing and PCR-based methods capacities led to a conclusion that at the current stage of technological development it is reasonable to use each of these approaches for specific purposes: domestic PCR-based tests — for diagnosis, and sequencing — for basic research of M. tuberculosis evolution and epidemiological monitoring. Promising areas of M. tuberculosis resistance research were proposed to develop new approaches for diagnosis and treatment of drug-resistant tuberculosis and to provide effective personalized therapy.

Introduction. Spinal anomalies are considered to be the most severe pathology of the axial skeleton. Intrauterine formation of deformity with its subsequent progression during growth is the reason for the need for surgical intervention. The prevalence of patients with congenital scoliosis in the total structure of spinal deformities is up to 2%. In terms of the malignancy of the course of the disease, children with unsegmented rod and rib synostosis represent one of the most unfavorable groups of patients. Aim. To perform a comparative analysis of the results of surgical treatment of children with congenital scoliosis with unilateral lateral vertebral segmentation disorder and rib synostosis using different techniques. Methods. The work is a monocenter cohort study of “case-control” type (III level of evidence). The design of the work is a monocenter cohort retro and prospective study. The results of surgical treatment of patients between 2010 and 2020 were analyzed. The study included 45 patients aged 3 to 7 years with the diagnosis of congenital scoliosis with unilateral lateral segmentation disorder of vertebral bodies and rib synostosis. The patients were divided into 2 groups depending on the surgical treatment method applied. In the first group (n = 24), patients underwent thoracoplasty with implantation of an individual rib/rib/vertebral distractor; in the second group (n = 21), patients underwent spinal surgery in the scope of vertebrotomy at the apex of the curvature and correction of the deformity with a multifocal spinal system. The data of medical records, as well as MSCT, radiographs, and pulse oscillometry were included in the analysis of the results. Results. Me (median) of scoliosis before treatment in group 1 patients 58.5, IQR = 19.75; after treatment — Me = 40.0, IQR = 20.0. Me of kyphosis before surgery 22, IQR = 4.5; after surgery Me = 26.0, IQR = 4.0. In the second group, Me of scoliosis before treatment 58.0, IQR = 3.0; after treatment, Me = 20.0, IQR = 6.0. Me of kyphosis before surgery 22, IQR = 2.0; after surgery Me 28.0, IQR = 4.0. When comparing MSCT data, group 1 patients showed an increase in lung tissue volume by 21% of the initial lung volume, in group 2 the increase amounted to 27%. The analysis of external respiratory function indices demonstrates improvement of reactive component indices by 21.1%, frequency dependence of resistive component by 46.4%, resistive component by 50% in group 1 patients, in group 2 there is an improvement of reactive component indices by 21.1%, resistive component by 50.9% and frequency dependence of reactive component by 46.7%. Conclusion. Corrective intervention on the spine at an early age makes it possible to achieve effective correction of the deformity; similar changes are observed both in lung volume and functional state of the respiratory system due to the mediated correction of the thorax shape.
