Analysis of statistical data in the federal districts of the Russian Federation provides opportunities to assess the quality of medical care delivery in children with cancer and plan further development with consideration for the point elimination of existing defects. Objective. Our aim was to analyze the main indicators characterizing medical care for children with cancer in the North-West Federal District. Methods. The study analyzed operative reports for 2017 provided by the executive public health authorities of 11 subjects of the Russian Federation affiliated to the North-West Federal District. Results. The pediatric population was 2 537 133 children (0-17 years), the pediatric oncological bed capacity - 174 (0.7 per 10 000 aged 0-17 years), the annual berth average occupancy - 290.7 days. 6 (54.5%) subjects did not provide pediatric population with departments of pediatric oncology, 4 (36.4%) subjects did not have bed capacity. The number of practitioners providing medical care to children with cancer was 38, 27 among them (71%; 0.1 per 10 thousand 0-17 years) had a certificate of pediatric oncologist. 2 (18.2%) subjects did not have pediatric oncologists in the medical stuff. The incidence of malignant tumors in children aged 0-17 was 15.6 (per 100,000), the prevalence was 92.6 (per 100,000), the mortality rate was 2.6 (per 100,000), one-year mortality rate - 4.5% (18/397). The number of patients identified actively was 11 (2.8%). 160 (40.3%) primary patients were sent to Federal medical facilities, 6 (1.5%) - left the territory of the Russian Federation for the further treatment. Conclusion. The incidence and mortality rates are rather low which indicates the defects in patient detection and lack of reliable follow-up data. The percentage of patients referred for treatment to Federal medical facilities is not very high; however, to interpret this indicator according to patient routing, we have to analyze the medical history of all the patients. We can assert that health care delivery service for children with oncological diseases is at an acceptable standard level but needs to be improved.

To investigate the effectiveness of the application of clinical guidelines “Enteral feeding of preterm infants” in infants below 32 weeks’ gestation. Material and methods. The study comprised 114 extremely preterm infants born before (2013-2014, group 1, n=53) and after (2014-2015, group 2, n=61) introduction of the clinical guidelines. Comparative analysis included breastfeeding frequency, the time of initiation of enteral feeding and achieving enteral feeds up to a volume of 150ml/kg/d, the incidence of necrotizing enterocolitis (NEC), gastrointestinal dysfunction, gastric bleeding, the use of breast milk fortifier, and the dynamics of infant postnatal physical growth. A comparative assessment also included the length of hospital stay, postconceptional age (PCA) and body weight at the time of hospital discharge. Results. After the introduction of clinical guidelines, 47 (77%) children received maternal colostrum on the first day of life. Breastfeeding was initiated significantly earlier: within 1 (1-5) day after birth in group 2 compared with 9 (2-28) days in group 1. Most infants received enteral feeding on the first day of life, though the infants in group 2 were administered it significantly earlier [7.5 hours (3.5-51) vs. 12 (6-144)]. A significant part of the extremely preterm infants was fed with breast milk. Sixteen (30%) infants in group 1 and almost twice fewer children in group 2 [10 (16%)] were on artificial feeding. In group 2, full enteral feeding was achieved significantly earlier than in group 1 [12 days (6-48) vs. 18.5 (13-47)], while the incidence of NEC in group 2 decreased 1.7-fold (14.8% vs. 24.5%). By 36 weeks’ PCA, the infants in group 2 had significantly higher body weight than babies in group 1 [2220 g (1420-2818) vs. 2050 g (950-3190)]. Conclusion. The clinical implementation of the guidelines “Enteral feeding of preterm infants” has resulted in significantly higher feeding efficiency in extremely preterm babies.

Relative and absolute hyperestrogenism and a change in the estradiol/progesterone (E2/P) ratio are of great importance in the pathogenesis of fibrocystic breast disease, which justifies the choice of progesterones for pathogenetic therapy. Transdermal progesterone gel is recommended in accordance with the instruction for medical use as monotherapy for this disease. Clinical findings show that the transdermal administration of progesterone is effective in reducing not only mastalgia, but also the number of cysts. A survey of physicians has demonstrated that unregistered drugs for this indication are used to treat fibrocystic breast disease. If there are indications, pharmacotherapy should be performed strictly in accordance with the instruction for medical use, which always contains information regarding what specific benign breast disease is treated with this drug, whether it is used as alone or as part of standard combination therapy, and which specific symptom should be eliminated if the drug is used symptomatically.

The aim of this study was to identify predictors of poor outcomes in patients hospitalized for severe acute exacerbation of COPD (AECOPD). Methods. This retrospective, observational cohort study was conducted in Pulmonology Department of a city hospital in 2015 - 2016 and involved patients hospitalized for severe AECOPD. Patients were divided according to outcomes. Poor outcomes included at least one of the followings: the need in invasive (IMV) or non-invasive (NIV) ventilation, admission to ICU, in-hospital death and COPD-related readmission during 2 months. Demographic, clinical, laboratory parameters, pulmonary function tests and blood gas analysis were analyzed; different multidimensional prognostic scores were also evaluated and compared. Results. Of 121 patients included, a poor outcome had occurred in 45 patients (37%). Among them, NIV was required in 21 (17%), IMV in 8 (6%), and admission to ICU in 16 patients (13%); death was registered in 6 patients (5%) and readmission in 27 (22%) of the patients. Patients with poor outcomes were admitted more frequently by ambulance (62% vs 40%; p = 0.003), more often were admitted to a hospital for AECOPD in the previous year (69% vs 45%; p = 0.0006), and had lower pH (p = 0.001), lower PaO2 (p = 0.001), higher PaCO2 (p = 0.001), and a worse score on several prognostic scales such as APACHE II (13.9 ± 5.4 vs 7.8 ± 3.6; p = 0.001), DECAF (2.4 ± 0.6 vs 1.5 ± 0.6; p = 0.001), BODEx (5.6 ± 1.8 vs 3.9 ± 1.1; p = 0.001), DOSE (2.9 ± 1.5 vs 2.2 ± 1.2; p = 0.029), and ADO (4.9 ± 1.5 vs 4.3 ± 1.3; p = 0.015) at admission. They more frequently received O2 therapy (87% vs 46%; p = 0.001) and had longer hospital stay (19.2 ± 6.2 days vs 12.5 ± 1.8 days; p = 0.001). Conclusions. Hypercapnia, hypoxemia and worse prognostic scores on admission predicted poor outcome in patients hospitalized for AECOPD during the previous year.

Assisted reproductive technologies (ART) are currently widely used around the world because of the increased prevalence of infertility (presently, about 15% of married couples suffer from infertility), as well as the increased access to treatment and public funding for this method. Hence, the number of children conceived by ART is steadily increasing every year. This review focuses on the pressing problem of the health status of children conceived by assisted reproductive technologies (ART) by analyzing modern publications on the state of physical, gonadal and psychosomatic development, features of the endocrine system and cardiometabolic diseases, the risk of imprinting changes, congenital malformations and oncological disorders. The data presented that there is no increased risk of childhood cancer or deterioration in quality of life. However, it is expected that the cardiovascular and metabolic risk factors found in childhood can worsen in later life and may ultimately be responsible for chronic cardiometabolic disease. Furthermore, the issue of fertility, especially in the male population conceived by ART, remains open, thus requiring additional longer-term research.

Today it is noted that the most cases of the hypospadias, cryptorchidism, testicular microlithiasis, as well as problems of semen quality and testicular germ cell tumours can be a clinical manifestation of testicular dysgenesis syndrome caused by abnormal development of reproductive organs. In the last decade, technological progress in the molecular genetics has made possible to carry out a directed search for genetic factors associated with reproductive disorders in men. In the review we attempted to analyze available literature data on the testicular dysgenesis syndrome and its constituent condition and also to consider the risk factors associated with its development. We give particular attention to the consideration of genetic factors that determine the manifestation of testicular microlithiasis, cryptorchidism and testicular germ cell tumors, both individual clinical conditions and in the syndrome of testicular dysgenesis. Knowledge of the genetic aspects of reproductive damage will allow us to characterize the complex interconnection of the human genome with the clinical phenotype, clarify the role of unfavorable factors of the environment and the lifestyle of the individual, and suggest new approaches to treatment.

Objective — to investigate the growth mechanisms of large uterine leiomyoma (LULM) on the basis of a clinical morphology examination, by providing immunohistochemical (IHC) characteristics of the expression of growth factors (transforming growth factor-beta (TGFβ) and platelet-derived endothelial cell growth factor (PD-ECGF)) and markers of stemness (CD117/c-kit, Connexin 43, Nestin) and proliferation (Ki-67). Subject and methods. The investigators examined surgical specimens from 38 women diagnosed with simple uterine leiomyoma (ULM), who had been divided into two groups: 1) 21 patients with LULM (>6 cm in diameter) (a study group); 2) 17 patients with small ULM (<4 cm in diameter) (a comparison group). Each group was also divided into two age subgroups (younger (<45 years) and older (≥45 years) subgroups (1a (n=12), 1b (n=9), 2a (n=8) and 2b (n=9), respectively. Histological specimens were used to make IHC examination with antibodies against TGFβ, PD-ECGF, CD117/ckit, Connexin 43, Nestin, and Ki-67. Results. The growth mechanisms of LULM of simple histological structure were found to be associated with the larger number of growth zones in the tumors, with their enhanced cellular proliferative activity, and with the appearance of cells with signs of stemness, which is combined with the preserved subsequent maturation of tumor cells and determines the benign nature of LULM. Conclusion. There were differences in the molecular profile of LULM and small ULM, as well as LULM in perimenopausal and young women by the expression levels of Ki-67, TGFβ, PD-ECGF, CD117, and Connexin 43, which can be used for diagnosis, prediction, and development of targeted therapies.

The morphological substrate of the disease was exclusively proliferative endothrombovasculitis without destructive changes in the walls of affected vessels. In addition, in the late stage of the disease, there was its unusual manifestation associated with inflammation of the mesentery arteriolar walls and with the formation of occlusive blood clots in their lumens, which led to severe abdominal diseases. The female patient showed a mosaic involvement of the loops of the bowel in the necrotic process as its separate segments, which was associated with damage to a large number of small vessels. The feature of the case is a set of 4 risk factors for a fatal disease outcome, such as age over 65 years, pulmonary, renal, and intestinal lesions.

Non-motor disturbances represented by sensory, affective, obsessive-compulsive disorders, cognitive dysfunction, sleep disturbances are often found in patients with dystonia and have a negative impact on their quality of life. The prevalence of sensory and affective disorders and sleep disturbances is above 50% in patients with cervical dystonia and is 25% in patients with blepharospasm, writing spasm; cognitive dysfunction is found in more than 25% of patients with focal dystonia. The relationship of nonmotor, in particular psychiatric disorders, with the impairment of social and everyday life and worsening of quality of life in whole was shown. Common pathophysiological mechanisms of non-motor disorders as well as approaches to treatment of these disorders are discussed. The authors present the results on the positive effect of botulinum toxin therapy that reduces cognitive dysfunction, sensory disorders and depressive syndrome. Non-medication treatment of non-motor disorders in patients with dystonia is considered.

Urothelial carcinoma is one of the most frequently diagnosed malignant tumors of the bladder and upper urinary tract, which ranks seventh in the pattern of cancer. Urothelial carcinoma of the renal pelvis is less common; but has a more aggressive clinical course and a worse prognosis than that of the bladder. This is due to the clinical and morphological features of this form of cancer, which, unlike bladder cancer, have not been studied enough. Objective — to comparatively analyze the morphological and immunophenotypic parameters of urothelial carcinomas of the renal pelvis and bladder. Subject and methods. Surgical specimens from 196 patients diagnosed with urothelial carcinoma of the renal pelvis and bladder were investigated. Paraffin sections were immunohistochemically examined using the standard protocol. Antibodies against CK5/6, CD138, CDX2 (≪Dako≫), CK7, CK14, CK20, CEA, CD10, CD117, EMA, E-Cadherin, HMWCK, p63, Uroplakin III, Vimentin (≪Novocastra≫), CD44, GATA-3, MUC1, MUC2, and MUC-5AC (≪Cell Marque≫) were used. Results. Most tumors (n=147 (75%)) were invasive. Of them, 65 (33%) cases had a histological structure of conventional urothelial cancer; and 3 (1.5%) had paradoxical differentiation. Divergent tumor zones were verified in 66 (34%) neoplasms; 4 (2%) cases showed an inverted growth pattern. Pseudosarcomatous stroma reaction in the invasion zones was verified in 9 (5%) cases. The tumor stage corresponded to pT2—pT4 in 128 (65%) tumors. Conclusion. Urothelial carcinomas of the renal pelvis and bladder show a broad spectrum of histological variants. The findings support that, unlike urothelial carcinomas of the bladder, the majority of primary urothelial carcinomas of the renal pelvis are high-grade and highly invasive.

This article presents a review of Russian and foreign literature about the impact of arterial hypertension (AH) on the risk of cognitive impairment and dementia. Large studies have demonstrated the effect of blood pressure (BP) on the risk of vascular dementia and Alzheimer’s disease (AD) in elderly and oldest old people as well as a role of antihypertensive therapy. There is evidence of a negative effect of hypertension in middle age on cognitive functions in late-life. Observational studies as a whole have shown the positive effect of antihypertensive therapy on the prevention of cognitive function and dementia. However, there are a number of limitations that dictate the need for further research on this issue. The importance of the interdisciplinary approach to treatment of cognitive impairment by cardiologists and/or therapists, together with neurologists, as well as complex treatment regimens, including correction of risk factors and neuroprotective therapy, is highlighted.

The development of autoimmune/inflammatory syndrome induced by adjuvants (ASIA) is associated with the hyperergic reaction of the human immune system. The development of autoimmune inflammation is preceded by contact with internal or external trigger factors (adjuvants) of immune disorders. ASIA is associated with an individual genetic predisposition that is probably associated with the carriage of HLA-DRB1*01 or HLA-DRB4. The paper presents five possible options for the impact of adjuvants in the pathogenesis of autoimmune disorders. It gives diagnostic criteria for the syndrome, as well as its clinical, laboratory and morphological manifestations. Emphasis is laid on the importance of morphological changes in the diagnosis of autoimmune disorders. The spectrum of morphological changes in ASIA is extensive. The tissues show signs of immune inflammation, such as lymphohistiocytic infiltration, granulomatous inflammation, and scleroderma-like changes. The characteristic feature is the regression of clinical, laboratory, and morphological manifestations after adjuvant removal.

The aim of the study was to provide a mathematical justification of the possibility of using 6.5 mm IRIS implants and to evaluate the results of orthopedic treatment in patients with partial loss of teeth. For the calculations was constructed of a composite three-dimensional computer models: the abutment screw-implant-bone. A total of 3 models were prepared: M1-implant in the spongy bone tissue, this model corresponds to the implantation on the HF when replacing one molar; M2-2 implants in the spongy bone tissue located at a distance of 4 mm connected via abutments, this model corresponds to the implantation of RF when replacing two molars; M3-implant in the cortical bone tissue, this model corresponds to the implantation of LF when replacing one molar. Loading of implants was carried out by occlusive force applied to its end surface. The results of the calculations showed that the equivalent stresses and limiting stresses of compression-tension are within the permissible values, which were obtained by us earlier in respect of the irregular implants and are consistent with the results of calculations for other systems of short implants. The clinical part of the work consisted in the treatment of 27 patients with partial loss of teeth, who had 41 iris evolution implants with a diameter of 5 mm, length of 6.5 mm after 3 years, there was a slow bone resorption in the cervical region not exceeding 0.35 mm, which corresponds to generally accepted international standards. During the first three years of operation there were no cases of loss of established implants. Thus, the data of mathematical modeling by finite element method and retrospective three-year analysis of prosthetics on IRIS evolution implants with length of 6.5 mm showed that the use of short implants in the recovery of upper and lower jaw molars is an effective method with a high success rate at long - term and resorption level of 0.34 mm.

In accordance with international and Russian guidelines for the management of patients with rheumatoid arthritis (RA), after its diagnosis, a synthetic disease-modifying antirheumatic drug is prescribed, among these drugs, methotrexate is anchor and, when the latter is impossible to use, leflunomide is commonly administered. Objective: to evaluate the efficacy and safety of a leflunomide generic (Elafra) during a multicenter follow-up. Subjects and methods. The investigation enrolled 347 patients aged over 18 years who met the 2010 ACR/EULAR criteria for RA, had its duration of less and more than 2 years, signed informed consent, and followed up in 29 centers of Russia. Elafra was prescribed at a saturating dose of 100 mg for the first 3 days, then 20 mg/day. There might be a temporary two-fold reduction in the dose when adverse events (AE) occurred. The patients were examined before and 4, 12 and 24 weeks after beginning leflunomide treatment. The treatment efficiency was evaluated with DAS28 and CDAI and by the physician global assessment. Results and discussion. The patients were divided into two groups: 1) 125 patients with RA of less than 2 years' duration and 2) 222 patients with RA of more than 2 years' duration. The mean age of patients in Group 1 was 48.7±12.9 years; that in Group 2 was 52.5±11.95 years; the mean disease duration was 11.9±7.8 and 90.99±54.28 months, respectively. During 24-week treatment, there was a highly significant decrease in all assessed clinical, laboratory parameters and indices of RA activity in both groups. At 4 weeks of treatment, the effect was observed in 91.8% of the patients in Group 1 and in 84.6% in Group 2, whereas at 12 weeks the effect was noted in almost all patients (99.1% and 96.9% in Groups 1 and 2, respectively). The highest rate of AE during Elafra therapy was recorded in the early periods: at 4 weeks, AE were noted in 6.5% of the patients in Group 1 and in 9.9% in Group 2, without needing to discontinue the drug. Treatment continuation decreased the rate of AE. Because of its intolerance, Elafra was discontinued due to in one case in Group 1 (diarrhea at 24 weeks of treatment) and in 6 cases in Group 2 (at 12 and 24 weeks of treatment). Conclusion. Treatment with leflunomide (Elafra) leads to the rapid development of its effect in early and late RA in most patients and is characterized by a good tolerability.

Among solid tumors, approximately 5% are bone sarcomas: osteosarcoma (3%) and Ewing's sarcoma (2%). Atypicality of the course of these diseases makes it difficult to diagnose them early. The article describes a series of clinical observations of patients with bone sarcomas, which illustrate the complexity of diagnosing diseases of this group.

Strontium ranelate (SR) that has a proven efficacy in reducing the risk of fractures and in increasing bone mineral density is currently recommended as a second choice drug for the treatment of severe osteoporosis (OP) in postmenopausal women and elderly men. Subjects and methods. In 2014-2015, a survey within the framework of the MARC program (The Use of Antiosteoporotic Drugs in Real Clinical Practice) was conducted in 1799 OP patients aged 25 to 92 years, who had been treated for this disease for at least one year. Among the respondents, there were 1696 people aged 50 years and older (mean age, 64±7 years; disease duration, 2.7±2.4 years) (86% women and 14% men) who were the subjects of this survey. Adherence to performed antiosteoporotic therapy was evaluated within the last 12 months before the survey by the following parameters: which drug had been taken; the number of packages used, treatment gaps and compliance with the treatment regimen. Results and discussion. The survey of the patients included in the study showed that 19% of them had received SR at any time over the course of the disease, and 8% had taken the drug within the year preceding the survey. Thus, SR remains a popular drug in real clinical practice for the treatment of severe OP in patients with no history of coronary heart disease, uncontrolled hypertension, cerebrovascular diseases, peripheral artery disease, and a predisposition to thrombosis and thromboembolism.

The aim of the investigation was to determine the characteristics of the immune response regulation for pulmonary tuberculosis (TB) and to analyze the role of regulatory T cells in the immunopathogenesis of TB with eosinophilia in the blood, depending on the clinical form of the disease and sensitivity of Micobacterium tuberculosis to anti-TB drugs. Materials and methods. 157 patients who were initially diagnosed with infiltrative and disseminated TB were examined. The material of the study was venous blood and culture of mononuclear leukocytes isolated from venous blood. The content of interleukin (IL) 4, IL-10 and transforming factor beta (TGFβ) in culture suspensions of mononuclear leukocytes in vitro and IL-5 in the blood was determined by enzyme-linked immunosorbent assay (ELISA) test. The expression of surface molecules CD4, CD20, CD25 and intracellular transcription factor Foxp3 by lymphocytes of the blood was evaluated by flow cytometry. The obtained results were analyzed by statistical methods. Results. It is shown that excessive generation of regulatory T cells in patients with TB is associated with eosinophilia of the blood and imbalance of immune response regulation mechanisms. In TB with eosinophilia, an increase in the number of Foxp3-positive regulatory T cells in the blood is combined with in vitro hypersecretion of anti-inflammatory cytokines TGFβ, IL-10, IL-4 and an increase in the content of CD20+ B lymphocytes and IL-5 in the blood. These changes are most pronounced in the disseminated form of TB in combination with drug resistance. Conclusion. Characteristics of immunoregulation at TB with blood eosinophilia are associated with activation of immunosuppression mechanisms and polarization of immune response towards Th2-dependent pathway.

A variety pathogenic mechanisms responsible for increase of blood pressure during stress exposure are described in detail. The importance of the sympathetic activation as a key link in the development of stress-induced AH and initiation of a cascade of pathophysiological reactions that realize their adverse effects at the level of the whole organism is underlined. Particular attention is paid to worksite AH as a variant of stress-induced hypertension due to its wide prevalence and association with an increased risk of cardiovascular complications, primarily myocardial infarction and stroke. Epidemiological data and results of recent metanalysis are presented, indicating the high significance of job strain as a risk factor for adverse cardiovascular events. The actual psychological stress reduction programs are described. Possibilities of using β-blockers in patients with stress-induced hypertension as drugs affecting the central pathogenetic trigger of this disease are considered. The advantages of using bisoprolol as a highly selective β-blocker are considered taking into account the available body of evidence for its effectiveness in patients with worksite AH, as well as its metabolic neutrality and target-organ protective properties.
