To study the effectiveness of two-step treatment of female patients with cervical intraepithelial neoplasia (CIN) associated with papillomavirus infection (PVI). Patients and methods. 126 female patients of reproductive age were examined (mean age – 31.4 ± 2.1 years), in whom CIN was associated with papillomavirus infection (PVI). In all cases, cervical pathologies – low-grade squamous intraepithelial lesions (L-SIL) have been found. In all patients treatment included a surgical step (laser and plasma energy) and medication, which was employed in 101 (80.1%) patients (treatment group). 25 (19.9%) women comprised the control group, since they did not receive post-operative pathogenetic therapy. In the treatment group, patients received an immunostimulating and antiviral drug inosine pranobex (IP) – Isoprinosine. Results. The effectiveness of treatment was assessed after 60 and 120 days from the termination of complex therapy (treatment group), or surgical intervention (control group). After a 60-day period, complete elimination of virus was noted 97 (96%) patients of the treatment group and in 18 (72%) of the control group. After 120 days, PVI relapse was recorded in 3 women of the treatment group (3%) and in 4 (22%) – of the control group among patients with complete elimination of virus. Conclusion. The use of IP as monotherapy is an optimal solution ensuring minimal risks of relapses of pathological PVI. Preparations of pure IFN and their inductors do not always promote complete elimination of PVI owing to interferon resistance of HPV-infected patients.

The aim of the present systematic literature review is to summarize data on the role of TLRs in maintaining homeostasis of the female genitals, in maintaining the physiological development of pregnancy, provision of anti-infective resistance in pregnant women with intrauterine infection. The review substantiates the importance of TLRs of female genitals as a necessary and determining factor in the reaction to various changes in the environment, and also responsible for changes in metabolic, structural, or energy, in the maintenance of anti-infective resistance and homeostasis. As universal regulators of vital activity of organism TLRs in conjunction with other receptors of innate immunity provide maintaining the general reactivity and anti-infective resistance at the physiological level. In physiologically developing pregnancy in a background of immunosuppression in response to pregnancy TLRs during contact with infectious and non-infectious pathogens stimulate the production of nonspecific adaptive immunity factors (defensins, cathelicidins, histatines, etc.), which together with the non-specific innate factors lysozyme, complement, properdin, etc. support anti-infective resistance of the female genitals at a high level at the beginning of the infectious process. Possible violations of the development of pregnancy may be accompanied by changes in the response of TLRs to infectious and non-infectious factors until hyper-reaction, excessive inflammation or apoptosis, which requires adequate management of pregnancy. Was established the significance of the influence of pathogens of infectious and noninfectious origin in intrauterine infection indirectly through TLRs in the homeostasis of the organism, on the formation of breaches in anti-infective resistance at the organism and community level the identification of new pathophysiological and immunological pathogenetic mechanisms of development of pathological processes. IUI is a penetration of microorganisms into the tissues of fetus and it's infection. The inhibition of the functional activity of TLRs is accompanied by the direct effect of the pathogen on the tissues, and during hyper-reaction of TLRs to pathogens revealed a pronounced inflammatory response in the fetus. The level of expression of TLRs correlates directly with the severity of the process that can be considered as early markers of infection. Depending on the nature of the pathogen an increased expression of one or the other TLRs is observed. Explained the lack of symptoms, the possibility of atypical manifestations, the asymptomatic course of infection.

AIM: To investigate the role of video-assisted subtotal esophageal resection in treatment of patients with benign esophageal diseases. MATERIAL AND METHODS: Fifty-one patients with benign esophageal diseases have undergone subtotal esophageal resection in our department for the period 2010-2017. Thoracoscopic technique was applied in 25 cases, open approach - in 26 patients. Total surgery time, thoracoscopic stage duration, length of hospital-stay (LOS), ICU-stay, Clavien-Dindo morbidity rates with separate registration of respiratory complications, mortality have been considered. RESULTS: Groups were similar in terms of age, gender, ASA status. Thoracoscopic stage duration gradually decreased from 175 to 65 min with average time of 102 (75; 123) min. Total surgery time was 390 (270; 495) min in group 1 and 465 (341; 561) min in the control group (р=0.035). Mean ICU-stay decreased up to 2 (1.25; 3.75) days compared with the control group (5 (3.92; 5.85) days, р<0.0001). Conversion rate was 8%. In the main group complications Clavien-Dindo grade 2 were detected in 10 (40%) patients compared with 20 (69%) cases in the control group (р=0.009). Respiratory complications occurred in 5 patients in group 1 and in 13 cases of the control group (р=0.039). Mortality was absent. CONCLUSION: Thoracoscopic subtotal esophageal resection may be advisable alternative to open surgery for patients with benign esophageal diseases due to lower postoperative morbidity and earlier rehabilitation followed by improved outcomes.

Assessment of the markers levels of endothelial dysfunction (ED): stable metabolites of nitric oxide (NOx), endothelin-1 (E1), homocysteine (HC), von Willebrand factor (vWF) and tissue plasminogen activator (tPA) in blood plasma of smoker and nonsmoker patients with arterial hypertension (AH) of low and moderate risk, not taking antihypertension therapy regularly. Material and methods. Totally, 124 AH patients included, 45 males and 79 females, mean age 51,4±6,5 y. O., mean AH duration 7,9±7,3 y. Controls included 35 healthy volunteers (20 males, 15 females). Concentration of NOx in plasma was measured with spectrophotometry, and of vWF, HC, E1 and tPA-with immune enzyme assay. Results. To evaluate the relation of smoking and ED markers levels, AH patients and controls were selected to subgroups according to smoking status: smoker (35,5%) and non-smoker (64,5%) AH patients; smoker (38%) and non-smoker (62%) controls. In smoker AH patients comparing to non-smoking there were significantly higher concentrations of NOx-48,2±18,8 mcM/L and 40,3±21,2 mcM/L, respectively (p<0,05), E1-1,2±0,16 and 0,6±0,2 fM/L, resp. (p<0,05), HC-25,7±6,04 and 16,2±6,5 mcM/L, resp. (p<0,05), vWF-1,39±0,7 and 1,1±0,6 mg/dL, resp (p<0,05) and tPA-13,05±6,2 and 8,5±6,2 mcM/L, resp. (p<0,05). There was correlation in the AH group, of NOx concentration and smoking (r=0,46, p<0,05), and tobacco smoking duration (r=0,83, p<0,05). Also, there were positive correlations of HC and smoking (r=0,4, p<0,05). In control group smokers had higher HC-20,7±5,3 and 17,2±4,7 mcM/L, resp. (p<0,05), vWF-1,3±0,8 and 0,8±0,6 mg/dL, resp. (p<0,05) and tPA-11,1±6,5 and 6,6±5,2 mcM/L, resp. (p<0,05). There were no significant changes in NOx and E1. Conclusion. In smokers of both AH and control groups the levels of HC, vWF and tPA were significantly higher in comparison with nonsmokers. In smoker AH patients the mean concentrations of NOx and E1 are higher than in non-smoker patients. Levels of ED are related with not only the fact of smoking itself (p<0,05), but smoking duration (p<0,05).

The article presents the review of latest studies devoted to assessment of the eosinophilic inflammation in chronic obstructive pulmonary disease (COPD) and opportunities for differential therapy of stable COPD and COPD therapy during exacerbation. Currently, there is no final definition what threshold blood level of eosinophils can be used for decision making in clinical practice. The only thing found out was that the high blood level of eosinophils could be a predictor of the risk of frequent exacerbations and the effectiveness of treatment with glucocorticosteroids.

© 2018 Russian Electronic Journal of Radiology.All right reserved. Purpose: To assess the possibilities of radiology diagnostics in patients with orbital trauma in postoperative period. Materials and methods: From 2015 to 2018 years in the clinic of Sechenov University 72 patients (100%) with traumatic injuries were examined. All patients (n = 72, 100%) were diagnosed with orbital trauma. After the admission all patients (n = 72, 100%) underwent multispiral computed tomography (MSCT) before and after the operation using Toshiba Aquilion One 640 modality, volume mode, slice thickness - 0.5 mm, bone and soft tissue reconstruction. Results: According to MSCT data in postoperative period with orbital volumes were reconstructed and symmetrical compared to the other side in 48 patients (64%). In 24 cases (33%) orbital volumes weren't reconstructed with remaining prolapse of orbital soft tissue structures in the maxillary sinus through the inferior orbital wall defect. Insufficient implantation of the inferior orbital wall prosthesis occurred in 7 patients (10%). Conclusion: MSCT is a method of choice in examining the patients with injuries of the midface. Computed tomography allows detailed determination of performed surgical treatment, to reveal the risk of postoperative complications and assess the dynamic of a patient in late periods.

© 2018 Russian Electronic Journal of Radiology.All right reserved. Purpose: Complications after hip/knee/other joint arthroplasty develop in approximately 1-1.5% of young people and in 2.5-3% of elderly patients. Despite the meager chance of developing negative consequences, they can affect anyone, especially those who did not follow the rigorous rehabilitation program. Complications after endoprosthetics of hip/knee/other joints results from incorrect postoperative care and physical activity after discharge from the hospital. The second reason is technical approach of the surgeon. And third is an inadequate preoperative examination. The aim of the article is to have a detailed description of short term, midterm and long-term complications after joint replacement surgeries and of the methods (clinical and radiological) to avoid those complications with all the required parameters.

Purpose: To assess the role of modern imaging techniques in the planning and implementation of hybrid interventions for an aortic arch aneurysm in an elderly patient with a burdened comorbid background. Materials and methods: Hybrid intervention in patient, 80 years, with acute rupture of the thoracic aorta was performed - aortic arch endografting from the level of the brachiocephalic trunk with endoprosthesis Zenit Alpha endoprosthesis with simultaneous "chimney" stent-graft Advanta V12 implantation in left common carotid artery and left-side carotid-subclavian bypass with Gore-Tex 6 mm prosthesis. Results: A female of 80 years with acute rupture of the thoracic aorta, massive rightside hemothorax has been successfully treated with hybrid intervention - endoprosthetics of the aorta with a subclavian left subclavian shunt. On the second day after procedure the patient underwent puncture of the right pleural cavity with subsequent drainage because of persisting respiratory failure. On the fourth day the patient was transferred from intensive care unit in stable condition, on the twelfth day the patient was discharged on postoperative day 12. Multislice computed tomography (MSCT) is commonly used for diagnosis of acute aortic pathology and planning the optimal method of surgical treatment, as it allows to obtain detailed images of the entire aorta and surrounding anatomical structures, three-dimensional reconstructions of blood vessels, to give an accurate assessment of the morphological characteristics of the aneurysmal sac, proximal and distal neck, degree of calcification and parietal thrombus, localization and extent of aortic wall defect. Conclusion: The use of new methods of endovascular and hybrid surgery in the treatment of aortic rupture of thoracic aortic aneurysms makes it possible to achieve clinical success even in extremely severe patients of elderly and senile age. The leading role in the planning of these operations belongs to actual imaging methods, primarily MSCT.

The literature data which demonstrate the possibilities of using computed tomography (CT) with contrast agents for the analysis of the deceased patients' bodies are presented. It is shown that postmortem CT angiography significantly expands the possibility of so-called noninvasive autopsy. The information on the features of the use of different types of con-trast agents as well as the main methods of postmortem CT angiography are presented. The use of targeted postmortem CT angiography allows to study the features of blood supply and to identify pathological changes in blood vessels of certain organs, in particular, coronary heart disease and cerebrovascular lesions. CT angiography of the whole body, especially multiphase postmortem CT angiography, allows to visualization of the cardiovascular system as a whole. The use of CT angiography is most effective for determining the source and volume of internal bleeding, the severity of thrombosis and the degree of stenosis of blood vessels, the type and prevalence of vascular malformations. We noted the complexity of the application and possible artifacts of postmortem CT angiography. It was concluded that postmortem CT angiography can be used to analyze of the bodies and clarify the tanatogenesis of deceased patients. We accented that postmortem CT angiography cannot fully replace the traditional autopsy despite its high specificity and sensitivity with regard to visualization of fatal bleeding.

Objective: to investigate the short- and long-term results of surgical median nerve decompression via classical and minimally invasive approaches in patients with carpal tunnel syndrome (CTS), as well as factors that influence surgical outcomes. Patients and methods. The investigation enrolled 70 patients (13 men and 57 women) aged 36 to 84 years (mean age, 62±10.8 years) who had undergone median nerve decompression. Surgery was performed in the classical way in 35 patients (Group 1) and via a minimally invasive access in the remaining 35 patients (Group 2). The efficiency of treatment was evaluated using the Boston Carpal Tunnel Questionnaire (BCTQ) and a visual analog scale for pain before and 1, 3, 6, and 12 months after surgery, as well as from patient satisfaction with surgical outcomes. Results. No complications of surgical treatment were detected. There was a marked reduction in pain and other neuropathic disorders just 1 month after surgery and a substantial hand functional improvement following 6 months. After 12 months, in Group 1, the mean BCTQ Symptom Severity Scale and Functional Deficit Scale scores decreased from 2.76 to 1.15 (p≤0.01) and from 2.72 to 1.24 (p≤0.01), respectively; in Group 2, these dropped from 2.86 to 1.14 (p≤0.01) and from 2.95 to 1.24 (p≤0.01), respectively. Complete recovery from sensory problems occurred in 24 (69%) patients in Group 1 and in 25 (71%) patients in Group 2; their partial recovery was observed in 11 (31%) and 10 (29%) patients in these groups, respectively. One 1 month following decompression, the patients in Group 1 had more severe pain syndrome than those in Group 2; these differences became statistically insignificant after 6 months. The patients were found to be highly satisfied with surgical treatment. Permanent numbness, subjective weakness, thenar muscle atrophy, stage III CTS, and diabetes mellitus (DM) were predictors for less pronounced improvement in BCTQ scores after surgical treatment (p<0.05). The paper describes a clinical case that achieved full postoperative occupational and home rehabilitation. Conclusion. The patients with CTS were observed to have a marked reduction in pain and other neuropathic disorders just one month after surgical decompression and a substantial hand functional improvement following 6 months. The benefit from a minimally invasive access is less severe pain syndrome at 1 month after surgery. The predictors of less successful results of surgery are age (the older the patient is, the greater likelihood of having a worse result), permanent numbness, subjective hand weakness, thenar muscle atrophy, DM, and stage III CTS.

Overweight provokes many metabolic and hemodynamic disorders. About 30% of inhabitants of the planet have overweight and prevalence of obesity increases by 10% every 10 years according to the WHO data. The probability of arterial hypertension in obese patients is 50% higher than in people with normal body mass. Framingham study showed that obesity is an independent, significant risk factor of ischemic heart disease, myocardial infarction, cerebral stroke and diabetes mellitus. The most dangerous is the central obesity with the preferential fat deposition in the abdomen. Combination of visceral obesity, violation of carbohydrate and lipid metabolism, arterial hypertension, and close pathogenic relationship between these factors underlie the isolated symptom complex known as metabolic syndrome. J. Vague was the first to describe relationship between abdominal obesity with cardiovascular disease and mortality in 1947. In our country G.F. Lang noticed common combination of arterial hypertension with obesity, lipid and carbohydrate metabolism disorders. Thus, metabolic syndrome significantly increases risk and severity of cardiovascular disease. Within last decades criteria of metabolic syndrome stays constant. The factors of insulin resistance and endothelial dysfunction as stages of the pathogenesis of the metabolic syndrome have been studied in detail. The mechanisms of insulin resistance and endothelial dysfunction are discussed in detail in this article as well as inflammatory markers and the significance of highly sensitive C-reactive protein.

Some authors consider that migraine proper does not lead to decreased cognitive functions, neuroimaging changes in the brain white matter are asymptomatic in migraine; and CI in patients with this condition is caused by comorbidities (depression, anxiety disorder) and/or concurrent cerebrovascular and neurodegenerative diseases. Other authors report the pathogenetic role of migraine in the development of CI and the importance of the frequency of headache attacks and neuroimaging changes in the brain matter in migraine. The paper reviews clinical trials dealing with the prevalence, causes, and pathogenesis of CI in patients with migraine. It sets forth the current principles of prevention and treatment of CI in patients with this condition.

Stroke is one of the leading causes of death and disability in the population, has a complex multifactorial nature and develops through the interaction of environmental factors and genetic predisposition, the pattern and mechanisms of which have been insufficiently studied. Ischemic stroke (IS) is most commonly encountered. Objective: to investigate the differential expression of microRNAs (miRNAs) in the plasma of patients in the acute and subacute stages of stroke. Patients and methods. The investigation enrolled 10 patients (5 men and 5 women; mean age, 64.5 years) with IS and 10 gender- and age-matched volunteers (a control group). A real-time polymerase chain reaction (PCR) was used to analyze the expression of 45 miRNAs isolated from the plasma samples of the patients on days 1 and 8 after onset of IS and isolated once from those of the controls. Results. A list of 45 miRNAs, that might be potential biomarkers and/or prognostic factors of stroke, was compiled. The investigation showed a decrease in let-7i-3p and miR-23a-3p miRNA expression in patients on the first day after onset of IS compared to the control group. The expression of miR-23a-3p increased in the patients at 8 days after IS. The patients with IS and the controls both showed gender differences in the expression of let-7i-5p and miR-92b-3p. Conclusion. The in-silico analysis revealed specific miRNA clusters associated with the peculiarities of clinical manifestations of IS. This may suggest that the patients with the favorable and unfavorable course of stroke may have its different molecular basis. In addition, it is necessary to take into account gender differences in the expression of individual miRNAs in assessing their significance in the pathogenesis and prognosis of IS.

Surgical treatment as accelerated functional recovery for discogenic radiculopathy has been proven to have advantages over medical treatment, the efficiency of which remains debatable. Objective: to investigate the efficiency of combination conservative treatment in patients with discogenic lumbosacral radiculopathy. Patients and methods. Thirty patients (12 men and 18 women; mean age, 39.5±2.2 years) with discogenic lumbosacral radiculopathy confirmed by magnetic resonance imaging were followed up. All the patients underwent combination conservative treatment (epidural glucocorticoid administration, analgesic therapy, and motor mode correction). They were surveyed using questionnaires (numeric pain rating scale (NPRS), Oswestry disability index, Hospital Anxiety and Depression Scale, the 12-Item Short Form (SF-12) of Quality of Life (QoL) Questionnaire on admission to the clinic, at 7-14 days after treatment (pain intensity and functional status), and in the long-term period (at 3, 6 and 12 months) after discharge. At baseline, the patients were severely disabled due to pain syndrome. The average Oswestry index was 57.9±3.7%, the back and leg pain intensity scores were 6.5±0.6 and 6.9±0.5, respectively, as evidenced by NPRC. The majority of patients were found to have the combined musculoskeletal sources of pain, such as a myofascial component in 56.7% and sacroiliac joint dysfunction in 43.3%. In these cases, nonsteroidal anti-inflammatory drugs and muscle relaxants were additionally used. Results. The conservative treatment resulted in a statistically significant clinical improvement with a preserved positive effect in the long term: at 1 year, the average Oswestry index was equal to 16.6±3.9%, the back and leg pain intensity scores were 1.7±0.5 and 1.6±0.5, respectively, as shown by NPRC (p<0.001 vs baseline). Within a year, only one female patient required surgical treatment; regression of large extrusions and sequesters, the average initial size of which reached 11.1 mm, was observed in 9 cases. Conclusion. The findings reflect the efficiency of conservative treatment and the expediency of detecting mixed musculoskeletal disorders and their correction in discogenic radiculopathy.
