Thiamphenicol glycinate acetylcysteinate (TGA) is a combination of thiamphenicol, a broad-spectrum antibiotic, and mucolytic drug N-acetylcysteine. This article is a review of pharmacological, microbiological, and clinical effects of this combined drug. Inhaled TGA could be considered as a worthy alternative for oral mucolytics and oral antibiotics in treatment of upper and lower airway diseases, such as acute and chronic rhinosinusitis, otitis media, tonsillitis, acute bronchitis, and acute exacerbation of chronic bronchitis and chronic obstructive pulmonary disease, in children and adults.

The combination of Alzheimer’s type dementia and vascular dementia is the third most common form of dementia, especially in the elderly. Most clinical forms of dementia are characterized by the presence of «overlap» symptoms of both neurodegenerative and vascular pathology, which makes it expedient to consider mixed dementia as a separate entity characterized by clinical presentations, course and the rate of progression of cognitive decline. Despite the lack of clinical guidelines for management of patients with mixed dementia, it seems appropriate to use strategies that have shown their effectiveness in various types of cognitive impairment.

Objective: The problem of drug interactions is increasingly important today because they may induce serious adverse events as well as interfere with efficacy of pharmacotherapy. Combinations of drugs are most often prescribed to patients presenting with comorbid pathology. The incidence of a combination of arterial hypertension (AH) and acid-dependent diseases (ADDs) varies widely ranging from 11.6 to 50%. One of combinations of drugs prescribed to such patients is a combination of calcium channel blocker amlodipine and proton pump inhibitor omeprazole. The latter in the human body undergoes biotransformation mediated at the level of cytochrome P450 by isoenzymes CYP2C19 and CYP3A4. Amlodipine is a substrate of the isoenzyme CYP3A4, which increases the probability of the development of interaction between these drugs. The purpose of our study was to investigate antihypertensive efficacy of amlodipine in patients suffering from arterial hypertension combined with acid-dependent diseases and additionally taking omeprazole. Method: Study included a total of 150 patients with AH and ADD. Antihypertensive therapy was evaluated by means of office measuring of arterial pressure (AP) and circadian monitoring of AP (CMAP). The followed-up patients with AH and ADD were divided into 2 groups. Group One was composed of hypertensive patients undergoing pharmacotherapy with 10 mg amlodipine, whose condition required due to exacerbation of ADD administration of omeprazole at a dose of 20 mg for a period from 3 to 4 weeks. Group Two comprised hypertensive patients receiving antihypertensive therapy consisting of 10 mg amlodipine, who were found to have remission of acid-dependent diseases, with no additional medication taken. Results: The obtained findings demonstrated that one of the commonly used drug combinations in treatment of patients with AH and ADD in ambulatory conditions was a combination of omeprazole and amlodipine, accounting for 7.1%. The results of office measurement of arterial pressure (AP) 2 weeks after initiating pharmacotherapy with omeprazole in patients with AH and ADD demonstrated that the patients receiving omeprazole in addition to antihypertensive therapy were found to have a statistically significant decrease in systolic arterial pressure (SAP) and statistically significantly more pronounced dynamics of a decrease in diastolic arterial pressure (SAP) (p<0.05) compared with those not receiving therapy with omeprazole. Also, in the group of patients taking omeprazole, the findings of circadian monitoring of blood pressure (CMAP) showed a statistically significant decrease in average circadian SAP, average circadian DAP, mean value of daytime SAP and mean value of nighttime SAP (p<0.05). Conclusion: The obtained findings demonstrated that simultaneous prescription of amlodipine and omeprazole to patients with concomitant pathology, i.e., AH and ADD, turned out to enhance the antihypertensive affect of amlodipine, which probably resulted from substrate competition of amlodipine and omeprazole at the level isoenzyme CYP 3A4 of cytochrome P450.

However, many of the modern chemotherapies are associated with cardiovascular toxicities that increases cardiovascular risk in cancer patients, including hypertension, heart failure, thrombosis and thromboembolism, cardiomyopathy, and arrhythmias. These side effects limitation restrict treatment options and farther perspectives. With increasing use of modern chemotherapies and prolongation of the cancer patients survival, the incidence of cardiovascular disease in this patient population will continue to increase. Accordingly,careful assessment and management of cardiovascular risk factors in cancer patients by oncologists and cardiologists working together is essential for optimal care.

A broad study of the pathogenetic mechanisms of the CVD onset and progression has led to understanding of the importance of endothelial dysfunction (ED) in these processes. During recent years intensive work has been conducted in the direction of searching for markers of ED. Metabolomics is an intensively advancing approach to early diagnostics of diseases. Metabolomic analysis based on mass spectrometry allows to study complete metabolic profiles and their deviations resulting from changes in expression of genes and RNA, protein activity, or environmental factors. Metabolomic analysis has already demonstrated significant results in the solving of different scientific and clinical problems. It appears to be a promising method for detecting early biomarkers of CVD. Various aspects of application of metabolomic profiling in the field of cardiovascular diseases are discussed in this article.

AIM: To determine the safest and the most effective surgical treatment of patients with cicatricle stenosis of tracheolaryngeal segment via analysis of different approaches.MATERIAL AND METHODS: For the period 1963-2015 at Petrovsky Russian Research Center for Surgery and Sechenov First Moscow State Medical University 1128 patients with cicatricle tracheal stenosis have been treated. There were 683 men and 445 women. 684 (60.6%) patients were young and the most employable (21-50 years). All patients were divided into 2 groups depending on time of treatment: the first one included 297 patients between 1963 and 2000, the second group - 831 patients between 2001 and 2015. In group 1 tracheolaryngeal anastomosis was made in 10 (16.9%) out of 59 patients who underwent tracheal resection. Previously indication for this surgery was cicatricle stenosis of cervical trachea and larynx with upper borderline of cicatricle changes at least 2 cm from vocal folds. In group 2 these procedures were more frequent. 94 (28.5%) out of 330 patients underwent tracheolaryngeal resection. Cranial borderline of lesion was within 0.5 cm from the vocal folds (only if posterior laryngeal wall at the level of cricoid cartilage was intact). Difficult patients are those who need for double-level or redo repair and procedures with tracheostomy.RESULTS: In the second group overall morbidity after tracheal resections followed by anastomosis was 5.6%. These complications were more common after tracheolaryngeal anastomosis (17%). There were no lethal outcomes after 94 tracheolaryngeal resections. Good long-term results were observed in 89.8% of patients after circular resection. Their quality of life was similar to that of healthy people. Preserved cicatricle tracheal segments during tracheal repair with T-shaped airway tube adversely affects quality of life in these patients in long-term period.

Background: Mesenchymal dysplasias or inherited connective tissue diseases are the group of diseases with deficiency of various components of connective tissue. Connective tissue disorders can affect different organs: skeleton, sight organ, skin, lungs, heart. But the most dangerous is vascular wall insufficiency leading to high risk of hemorrhage, especially during pregnancy and delivery due to hemodynamic and hormonal effects on the walls of the modified vessels. Aim: To evaluate the risk of complications during the pregnancy and delivery in patients with mesenchymal dysplasias. Study design: Fifty-six pregnancies in patients with mesenchymal dysplasias, including subclinical forms of diseases: 23 with Marfan syndrome (I group), 22 with Ehlers–Danlos syndrome (II group), and 11 with Osler–Weber–Rendu syndrome (hereditary hemorrhagic telangiectasia) (III group) of the age from 18 to 36. The study included retrospective analysis (for the period from 1993 to 2005) and prospective study. Results of study showed high risk of life-threatening complications during pregnancy and delivery, especially the risk of hemorrhage and cardiovascular complications. In all the patients, we observed the progression of bleeding or development of bleeding in new localizations (epistaxis in 27 patients, easy brushing in 22, skin and mucosa telangiectasia in 20, gastrointestinal bleedings in 4, hemoptysis in 4, hematomas for minor traumas in 14, conjunctivas hemorrhages in 5). Conclusion: The pathogenesis of bleeding in such patients has mixed pattern: besides vascular wall pathology coagulation deficiency plays some role. The preferred delivery method for such patients is caesarean section. Deep vaginal ruptures and serious hemorrhage accompany vaginal delivery.

Venous surgery prescribed to the patients receiving anticoagulation therapy for the treatment of atrial fibrillation especially with the use of warfarin is considered to constitute a serious challenge due to the increased risk of the development of venous thromboembolism and other hemorrhagic complications in case of withdrawal of the anticoagulant. A clinical case of successful perioperative management of the patient with varicose veins with the use of long-term warfarin therapy for the management of atrial fibrillation is presented. Several surgical clinics refused to treat the patient on a regular basis on the ground of impracticability of any invasive procedures because of the patient’s condition taking into consideration the involuntary intake of the anticoagulation agent and the concomitant cardiac pathology. We performed the primary clinical examination and duplex ultrasound study of the patient who was found to have varicose veins in right lower extremity (С2, 3S, Ер, Аs, p, Pr2,18, LII) with the international normalized ratio (INR) being 3,64. We confirmed the indication for the surgical treatment and offered the patient high ligation, stripping and phlebectomy. Prior to surgery, the patient was switched to a subcutaneous injection of enoxaparin. After reducing INR down to less the 2.0, we performed surgery under spinal anesthesia. The anticoagulation treatment was restarted 12 hours after the operation. No complications was documented within the first weeks after the intervention. The patient was switched back to warfarin therapy.

The issues of epidemiology, diagnosis and treatment of CIN are discussed. Emphasis is put on a complex approach to treating patients with HPVI-associated CIN. Special attention is paid to studying the mechanisms of dysregulation of immune response during the period of human papillomavirus virus (HPV) persistence, which promotes immune suppression and is considered to be a necessary precondition for progression of HPV-associated cancer. Based on analysis of literature sources, the authors show that high oncogenic risk E6 and E7 HPV types interact with key proteins of interferon signalling pathway, inhibiting its production. This accounts for insufficient effectiveness of preparations of pure interferons and their inductors for treatment of HPV infection. From the pathogenetic positions, the use of inosine pranobex as a medication in complex therapy would be appropriate, since it ensures complete elimination of HPV and reduces the frequency of HPV infection recurrences.

The objective of the research was to elaborate experimental-theoretical and clinic-bacteriological rationale for the application of laser diagnostic for identification of main pathogens of purulent-inflammatory processes in maxillofacial area. For germs identification by giant Raman scattering effect SERS-substrate with nano silver metallic balls, reference strains (Ps. aeruginosa 27853 and S. aureus 25923) and clinical cultures of Staphylococcus, Bacillus and Escherichia coli were used. Using an example of purulent inflammation pathogens we considered that each of bacterial species is characterized by individual spectral lines of Raman scattering, which allows to identify them in short term (1-2 min). Moreover the proposed method is highly sensitive (105-106 CFU/ml). Creation of germs library and device portability makes use of laser diagnostic for express-indication purulent infections possible directly in clinical conditions. Thus, analytical capability, quick result, high sensitivity and peculiarity, economical effectiveness due to lack of necessity to use growth medium and to transport it to microbiological lab gives an opportunity to consider laser diagnostic as a perspective universal express-method of clinical microbiology.

The CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) equation was developed in an effort to create a more correct formula to estimate GFR, however, it is not able to assess split renal function. Objective. This paper aims to present how numerical analysis of abdominal multispiral computed tomography (MSCT) results correlate with data of CKD-EPI equation. Materials and methods. In this Institutional prospective cohort study, MSCT scans of 16 patients undergoing multiphasic renal protocol with 3D-reconstruction and numerical estimation were reviewed. Comparison was made by means of Pearson coefficient and Youden index. Results. MSCT-based methods for the calculation of split renal function with 3Dmodels showed strong correlation with CKD-EPI (p<0.001). Conclusion. Data received using the 3D-MSCT in comparison with CKD-EPI equation are equally accurate with low bias in GFR-assessment. However new approach has great advantages, because allows for both acquiring detailed data on clinical anatomy and evaluation of renal function, that made it not only precise but also more informative for decision-making in clinical practice. Such application of high-tech imaging method applied to the field of radiology may alter the course of patients' management when pathologic process is just beginning to correct premorbid conditions.

The structure of the atherosclerotic plaque plays an important role in the development of the mechanism of intracoronary thrombosis. Currently, there are various radiological methods for diagnosis of atherosclerotic plaques of the coronary arteries. The current review reveals the theme of "indirect" signs of instability of atherosclerotic plaques, their combinations and occurrence, detected by computed tomography. Retrospective studies have shown the feasibility of these signs of plaques in the assessment of the prognosis of acute coronary events. The review compares the results of computed tomography (CT) and intravascular ultrasound, which is the gold standard in the diagnosis of atherosclerotic plaque morphology.

Replication of Francisella and Shigella in cytosole of host cell is correlated with their ability to escape from phagosome (containing bacteria vacuole) and to modulate innate immunity of host. Francisella T6CC and some undeterminated products of pathogenicity island's genes take part in such processes. Shigella T3CC and autotransporter protein IscA provide this processes together with spreading bacteria intra colonic epithelium.

Aim of the study was to explore the role of the FGF-23/sKlotho/sclerostin ratio disturbance in the determining of cardiovascular risk in end stage renal disease (ESRD) patients, receiving treatment with regular hemodialysis (ÍD) or hemodiafiltration (ÍDF) online in Russia. Materials and methods. 42 patients with ESRD, at the age of 18-55 years, treated with HD or HDF on line for at least 6 months, were examined. 22 (52.3%) patients received traditional HD, the remaining 20 (47.7%) - HDF online. In all the patients, in addition to a general examination, the serum levels of FGF-23, sKlotho, sclerostine (by ELISA), their associations with cardiovascular risk factors (left ventricular hypertrophy (LVH), acute coronary syndrome (ACS), serum troponin I levels) with the numbers of techniques (ECG; Eho-CGF (with calculation of left ventricular myocardium mass index (LVMMI), as well as the relative thickness of the walls of the left ventricle (RWT); sphygmography (central (aortal) blood pressure (CBP), subendocardial blood flow (SBF) - by Sphygmocor), and the effect of regular HD and HDF on serum levels of the studied markers, were assessed. Results and discussion. An independent effect of FGF-23 on the risk of LVH, as well as on the increase of serum troponin I in the studied ESRD patients [β=3.576 p<0.01, and β=1.115, p<0.05, respectively] was found. Serum Klotho was the factor most associated with the CBP [β=-0.023; p<0.001]. The increased serum sclerostin was correlated with a lower incidence of both reduced SBF [r=0.492; p<0.05], symptoms of coronary heart disease [r=-0.449; p<0.05] and rhythm disturbances [r=-0.446; p<0.05]. In addition, in HD patients higher FGF-23 and lower Klotho and sclerostine serum levels were associated with: inadequate dialysis syndrome (Kt/V <1.1; r=0.463; p<0.05), chronic inflammation (C-reactive protein >10 mg/L; r=0.612; p<0.01), and with a decrease in serum albumin level (<35 g/l; r=0.459; p<0.05). The FGF-23/sKlotho/sclerostin ratio disturbance was more pronounced in patients treated with traditional HD then HDF online. A direct correlation (r=0.445; p<0.05) was established between FGF-23 serum levels and serum phosphorus, which was more pronounced in HD patients (r=0.545; p<0.01). Conclusion. In HD and HDF ESRD patients, higher serum FGF-23 and lower sKlotho and sclerostin levels were associated with a chronic inflammation, malnutrition, secondary hyperparathyroidism, and may considered as predictors of cardiovascular complications such as LVH, ACS, rhythm disturbances, persisting of subincreased serum troponin I.

The article covers a little-known episode from World War I, concerning the work of one of the foreign detachments (hospitals) in the Russian Tsarist army. The large-scale sanitary losses and epidemics of infectious diseases, which accompanied the war, required special efforts from the medical service of the Russian army. The Russian Red Cross Society (RRCS), which had monopoly rights to organize medical care during the war, did not cope with the problems that arose. In connection with this, the international community, primarily the medical personnel of neutral and allied states, in particular, England and America, played a big role in the provision of medical care to the wounded Russian army. The activities of foreign doctors, nurses and hospitals were carried out under the auspices of the RRCS in the framework of the humanitarian assistance that allies provided to Russia during World War I. Based on archival documents and materials from RRCS periodicals for 1914–1917, the activities of the medical unit of the North American United States in the Caucasian theater of military operations and the American hospital organized by it on the territory of Persia (the town of Khoy) are investigated. The materials under review single out a number of problems in the provision of medical assistance to the troops of the Caucasian Front, requiring special urgency and unprecedented work from the American specialists in Khoy. Throughout the period under review, anti-epidemic, clinical, evacuation and charitable activities predominated the detachment’s work. Doctors and nurses of the detachment risked their lives in performing their duties during typhus epidemics. It is noted that in addition to American doctors and nurses, Russian doctors and nurses worked at the hospital.

The article is devoted to the analysis of the evident scientific method of Galen, which establishes the necessity of correct diagnosis of diseases, determination of true symptoms and causes of diseases, which results in the choice of the exact method of treatment. The article focuses on how Galen seeks to achieve reliable knowledge based on an undeniable logical necessity. Logical reliability is contrasted with "dialectical", that is, probabilistic judgments, often leading to the opposite of what was originally asserted in them. Probabilistic judgments were characteristic of the Stoic philosophical school, with which Galen hotly argues, asserting his understanding of truth. Truth, in his opinion, is achieved through facts based on true premises. The criterion of truth for Galen is the study of the device of a living organism, and the logical conclusions depend on the accuracy of knowledge of human anatomy. Thus, the nature of the proof judgments of Galen depends on their practical content and not on the formal and logical structure offered by the Stoics when studying the functions of the human body, which ultimately leads to incorrect methods of treatment.

TCP is defined when platelet count less than 150 × 109/L. the Diagnostic search when TCP should begin with the establishment of a pathogenic variant with subsequent verification of the main reasons for TCP. This allows you to select pathogenetic therapy of the disease (glucocorticoids, immunosuppressants, anticoagulants) and to influence the basic process.

Exosomes (vesicles with the size of 30-150 nm) are formed in multivesicular bodies (MVB) by invagination of early endosome membranes and mediate intercellular interactions. Exosomes are secreted by various kinds of cells, their content might be represented by proteins, lipids and nucleic acids, which reflect the functional state of donor cells. The effect of exosomes on recipient cells depends on their quantity and characteristics of their «load». Comparatively recently, placental exosomes secreted by various placental cells have been isolated from blood of pregnant women. A specific protein - placental alkaline phosphatase (PLAP) - has been determined for these exosomes. PLAP-positive exosomes can be found in maternal blood as soon as in the first trimester of pregnancy, their number increases with maturation of the foetus and reaches its maximum by the moment of birth. Although the functional significance of placental exosomes is still investigated, some authors relate changes in the placental exosome profile (their number and composition) to placental dysfunction underlying the development of complications of pregnancy. Isolation of exosomes from blood of pregnant women (fluid biopsy) and determination of their biological characteristics might be regarded as early noninvasive diagnosis of structural and functional placental abnormalities. The appearing evidence of blastocyst-secreted exosomes and their role in modulating maternal immunity and endometrial receptiveness during implantation are also promising. The review presents data about the biogenesis, structure and functions of exosomes and the role of placenta-associated exosomes in the development of physiological and complicated pregnancy, and also about the possibility of using exosomes as a marker of the state of the blastocyst in assisted reproductive technologies, in particular, in oocyte donation and surrogate motherhood.
