[Application of optical coherence tomography in the assessment of the posterior lens capsule during anti-angiogenic therapy]. / Primenenie opticheskoi kogerentnoi tomografii v otsenke zadnei kapsuly khrustalika na fone provedeniya antiangiogennoi terapii.

Intravitreal injection (IVI) of anti-angiogenic drugs is one of the most common therapeutic procedures in ophthalmology. In recent years, a new non-contact study method has been developed - anterior segment optical coherence tomography (AS-OCT), which allows the formation of three-dimensional images of the lens and provides more detailed information about its structure and morphology. PURPOSE: This study uses optical coherence tomography method to analyze the risks of developing changes in the posterior lens capsule in patients after IVI of an anti-angiogenic drug. MATERIAL AND METHODS: The study involved 100 people (14 men and 86 women) with a natural lens and neovascular age-related macular degeneration (nAMD). The average age was 70.57±7.98 years. During the study (12 months), all patients underwent IVI of an anti-angiogenic drug aflibercept in the treat-and-extend (T&E) mode. All subjects were divided into 2 groups: with a total number of IVI less than 10 - group 1 (50 patients), and more than 10 IVI - group 2 (50 patients, of which 49 were included in the study). All patients underwent OCT using the Optopol REVO NX device (Poland) with the Anterior B-scan Wide protocol before inclusion in the study, as well as after 3, 6 and 12 months. RESULTS: It was found that the risk of developing a posterior lens capsule rupture, visualized using OCT, depends on the total number of IVI (correlation coefficient 0.473 p=0.001): the more IVI, the higher the probability that damage to the posterior capsule will occur after the next IVI, and after the 15th injection the risk of developing damage to the posterior capsule increases sharply. CONCLUSION: The astudy analyzed the risk factors for the development of posterior lens capsule damage that can be detected using OCT, and presented three risk groups for the development of rupture (or damage) of the posterior lens capsule depending on the number of intravitreal injections performed.

[Age determination by microstructural features of human cricoid cartilage]. / Opredelenie vozrasta po mikrostrukturnym parametram perstnevidnogo khryashcha cheloveka.

THE AIM OF THE STUDY: Was to develop the age determination's technology by the morphometric features of the human cricoid cartilage using a regression analysis method. Cricoid cartilages of 65 variously-aged males were examined. The number of histomorphometric parameters equal 16 for each sample were determined and measured on the histological sections. A descriptive statistical processing of data using the regression analysis method was done, as a result of which the model of age determination was developed. This model has a high predictive accuracy, where the prediction error was less than 5 years in 64.62% of cases. The practical use of this model may be limited by the morphometric parameters' number translating complication to calculate the formula. The developed method can be improved while increasing the sample and conducting further statistical processing, and in the future it can be used in the age determination in forensic medical examination.

[Shaping approaches to standardization of oropharynx mucous membrane assessment of immunological parameters]. / Formirovanie podkhodov k standartizatsii issledovaniya immunologicheskikh parametrov slizistoi obolochki rotoglotki.

Basis of acute pharyngitis pathogenesis is an inflammatory process at the entrance gate of the infection. Therefore, local immunity study proves to be the most informative. Difficulty in making that type of assessment is lack of generally accepted reference values and biological sampling techniques. OBJECTIVE: Validation of biological sampling techniques to study the parameters of local mucosal immunity in oropharynx acute inflammatory diseases. MATERIAL AND METHODS: 30 people with acute catarrhal pharyngitis with intoxication syndrome were examined. The sampling was carried out in 7 different ways. 1. Collect saliva samples using the passive drool collection method. 2. Collect saliva, using cotton swabs placed into the mouth for 3 minutes. 3. Cotton swabs wrapped around a metal probe was placed on palatine tonsils and lateral walls of the oropharynx. 4. Instead of a cotton swab, a disc of laboratory filter paper with a diameter of 0.7 cm was used. 5. Scrape by the mucous membrane of the palatine tonsils and lateral walls of the oropharynx were made with a cytobrush. 6. Using a cytobrush, scrapings were made from the mucous membrane of only the posterior pharyngeal wall, excluding the region of the palatine tonsils. 7. Using a cytobrush to make scrapings from the only palatine tonsils mucous membrane. RT-PCR was used to determine IL-1ß mRNA. RESULTS: Minimal IL-1ß mRNA values were detected in saliva collected by passive flow (0.095 [0; 3.45] units) and on a cotton swab (0.21 [0.1; 3.82] units). IL-1ß mRNA in the material collected by methods No. 3 and No. 4 on a cotton swab and a paper disk did not differ significantly from each other. Its level was higher than in saliva and lower than in scrapings. The maximum result was revealed with method No. 5 when simultaneously taking scrapings from the palatine tonsils and posterior pharyngeal wall mucous membrane (4.76 [0.92; 8.13] units). The expression of IL-1ß mRNA in the material obtained by methods No. 6 and No. 7 did not differ significantly from each other. CONCLUSION: Separated scrapings collecting from the palatine tonsils or posterior pharyngeal wall mucous membrane will allow assessing the inflammatory response autonomously in the lymphoid tissue and separately on the mucosa of the posterior pharyngeal wall. The mucosal scraping technique was the most effective for assessing cytokines in the oropharyngeal mucosal membrane.

However, their share of the total number of violent death cases is increasing. The labor intensity of medical forensic examinations and the number of examination methods used are increasing. Regional differences in the studied indicators are revealed. The presented metadata can be used to improve the workflow management of forensic medical departments and monitor the effectiveness of improvements. The findings confirm the need to modernize and adapt the regulatory and procedural framework of the expert work.

[Retrograde intrarenal surgery using a 1.94 m superpulsed thulium fiber laser].

INTRODUCTION: surgical treatment of urinary stone disease plays an important role in urological practice. Stone fragmentation can be performed using various lithotripters, from which Holmium fiber laser (Ho: YAG) has currently taken the main place. According to the current literature, a superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power output of 40 W showed in vitro higher efficiency compared to Ho: YAG, while having the same safety profile. The use of a thulium fiber laser with a pulse energy of 0.025-6 J and a high repetition rate (up to 1600 Hz) allows to most effectively perform stone dusting during retrograde intrarenal surgery (RIRS). AIM: to improve the performance of RIRS using the 1.94m superpulsed thulium fiber laser. MATERIALS AND METHODS: a total of 152 patients with renal stones who were treated during the period from February 2018 to July 2019 were included in the study. The analysis of the laser settings, their effect on retropulsion and visibility when performing RIRS using a superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power output of 40 W, a peak power of 500 W, as well as an assessment of the stone-free rate the first postoperative day and 3 months after the procedure was done. RESULTS: The most frequently used settings were as following: 0.5 J, 30 Hz, 15 W (No. 1), 0.15 J, 200 Hz, 30 W (No. 2), 0.8 J, 31.25 Hz, 25 W (No. 3), 0.8 J, 37.5 Hz, 30 W (No. 4). The statistical analysis of the influence of the settings on the quality of endoscopic imaging and retropulsion was carried out. In addition, the features of each settings were analyzed. The stone-free rate on the first postoperative day was evaluated using low-dose CT. CONCLUSION: A superpulsed thulium fiber laser with a wavelength of 1.94 m and a maximum power of 500 W has shown high efficiency in clinical practice when performing RIRS, since it allows to have good endoscopic imaging, minimal retropulsion, and to perform stone dusting, which had a positive effect on the stone-free rate. Optimization of the settings of thulium fiber lithotripsy may improve the results of surgical treatment of urinary stone disease.

[Correction of halitosis in chronic inflammatory diseases of the oropharynx in adults]. / Korrektsiya galitoza pri khronicheskikh vospalitel'nykh zabolevaniyakh rotoglotki u vzroslykh.

Approximately 25% of the world population suffer from halitosis, making it a significant medico-social issue. It is one of the clinical signs of chronic inflammatory diseases of the oropharynx and is commonly caused by the persistence some bacteria in the oral cavity and in the oropharynx. These in turn facilitate formation of volatile sulphur compounds. OBJECTIVE: To evaluate the effectiveness and safety of the probiotic strain Streptococcus salivarius K12 in the Bactoblis product in exacerbation of chronic inflammatory diseases of the oropharynx. MATERIAL AND METHODS: 45 patients diagnosed with a diagnosis of exacerbation of chronic pharyngitis were studied, gastroesophageal reflux disease was found in 33 patients. After a microbiological testing, all patients were prescribed probiotic strain Streptococcus salivarius K12 in the amount of 1×109 colony-forming units (CFU) in the form of tablets for resorption as monotherapy for 14 days. The assessment of the therapy was based on physical examination data and on the subjective estimation of the clinical symptoms using a 10-point visual analog scale (VAS) before the start of the treatment and on the 5th and on the 7th day of the therapy. RESULTS: According to the microbiological analysis was revealed the growth of Staphylococcus aureus, Candida albicans, Pseudomonas aeruginosa, Streptococcus agalactiae, Streptococcus viridans which was seen within 103-105 CFU. A significant clinical progress was achieved for all three analyzed signs of diseases (the severity of pain when swallowing, a feeling of perspiration (foreign body) in the pharynx, halitosis), within the statistical significance between the 1st and the 7th day and the 7th and the 14th day of the surveillance. The pain severity was decreased from 5.69±0.39 points to 2.69±0.34 points on the 7th day and to 0.08±0.05 point on the 14th day from the start of the therapy, itchy throat (foreign body sensation) was relived from 6.88±0.23 points to 3.54±0.29 points on the 7th day and to 0.69±0.12 point on the 14th day of the therapy. In addition, there was a decline in the severity of halitosis from 6.16±0.31 points to 2.47±0.44 points on the 7th day and to 0.68±0.29 point on the 14th day of the therapy. CONCLUSION: Topical application of a drug containing a probiotic Streptococcus salivarius K12, in case of chronic inflammatory diseases of the oropharynx of various etiologies, showed satisfactory effectiveness in the regression of the main symptoms of the exacerbation of the inflammatory process, expressed through pain in the throat when swallowing, halitosis and the foreign body sensation in the oropharynx.

[Epidemiological analysis of violent death and cases of not established death cases in Russian Federation (2009-2018)]. / Epidemiologicheskii analiz pokazatelei nasil'stvennoi smerti i sluchaev neustanovleniya prichiny smerti po Rossiiskoi Federatsii (po materialam 2009­2018 gg.).

The paper presents the results of an epidemiological analysis of statistical data on the number of deaths from violent deaths, which cause has not been established; unidentified and unclaimed corpses in forensic medical expertise in Russia as a whole and in individual federal districts for the period from 2009 to 2018. Percentage indicators and share values of the circumstances due to which the death cause was not established are given. It was found that on the basis of a steady decreasing trend in number of violent deaths, the number of corpses with an unknown death cause is growing, mainly due to putrefactive changes in corpses of adults and due to the burning of children corpses. The presence of a strong correlation between the number of unclaimed and unidentified corpses with the number of forensic medical expertise, when the cause of death was not established, was shown. Based on the analysis results at the macro level (federal districts), some interregional differences in the structure of the analyzed indicators were revealed. The results obtained make it possible to confirm the relevance of existing clusters of scientific research and to form new ones, to place accents in the directions of the postgraduate education of specialists.

CONCLUSION: The article illustrates the importance of developing highly sensitive and highly specific methods for the rapid diagnosis of inflammatory diseases of the pharynx. The presented technology can be used in clinical practice in future.

[Relation of Functional Activity of Platelets to Prognosis of Unfavorable Cardiovascular Events in Patients with Acute Coronary Syndrome. Results of a Registry Study].

AIM: to assess relation ofhigh functional activity ofplatelets to prognosis ofunfavorable cardiovascular events in patients with Acute Coronary Syndrome (ACS). MATERIALS: The study was based on the data of a single center ACS registry conducted in the Central Clinical Hospital of the Presidential Affairs Department of Russian Federation. Of 529 included patients in 425 without contraindications to double antiplatelet therapy we carried out analysis of dependence of 30 days level of unfavorable events on parameters of functional activity of platelets. RESULTS: High on-treatment platelet reactivity (HTPR) was found to be associated with 3.5 increase of mortality in the group of patients with high cardiovascular risk. Logistic model of prognosis of unfavorable events based on multifactorial analysis of data from patients with measured platelet aggregation included chronic kidney disease, type of myocardial infarction, and degree ofplatelet aggregation >45%. C -statistic was equal to 0.77. We also present in this paper discussion of problems related to studying approaches to individualization of anti-aggregation therapy in real clinical practice and problems of organization ofsimilar studies. CONCLUSION: The study showed that patients with ACS increased platelet aggregation, as well as chronic kidney disease and type 2 MI are associated with a 30 day prognosis of adverse events.

[Acute Coronary Syndrome Registry of High Risk Patients: 30-Day Outcome].

AIM: The aim of the study is to evaluate important additional cardiovascular (CV) risk factors of major adverse cardiac events (MACE) in patients with acute coronary syndrome (ACS) during the first 30 days after index event. MATERIALS AND METHODS: Overall 750 patients with ACS were enrolled in the single center prospective registry from 2012-2015yy. 569 patients received dual antiplatelet therapy and in 425 cases platelet function testing (PFT) were performed. Most of the patients characterized as high risk elderly patients with multiple CV risk factors and high comorbidity index. RESULTS: At 30-day follow-up the mortality rate was 10,1%. Singlevariate analysis showed strong association between MACE and age, atrial fibrillation, stroke, chronic kidney disease, low ejection fraction, type 2 myocardial infarction (T2MI). Multivariate analysis showed that high-on-treatment platelet reactivity (PFT> 45%) with odds ratio 4.418 (p=0.0001), chronic kidney disease (OR 6.538 p=0.001) and T2MI (OR 1.925 p=0.0001) were significantly associated with adverse outcome. CONCLUSION: ACS registry showed high mortality level in real-life practice compared with randomized clinical trials due to the high prevalence of elderly patients with high comorbidity index. Patients with T2MI have significantly more severe prognosis and chronic kidney disease associated with increased MACE. PFT in this category of patients is reasonable for more accurate risk stratification.

[Treatment of patients with lower urinary tract symptoms in Moscow].

INTRODUCTION: In recent years, there has been a persistent tendency to a decrease in surgical treatment of patients with lower urinary symptoms (LUTS). This fact can be explained by variety drugs which have acceptable safety and high efficiency for treatment of urinary disorders. As part of our survey of men in Moscow region, the trends in prescribing the different drugs for the LUTS was studied. In addition, the duration of therapy and patient adherence were analyzed. MATERIALS AND METHODS: A prospective multicenter epidemiological study "Characteristics of lower urinary tract symptoms in men in the Moscow region" was carried out using data obtained from April 1 to May 31, 2017 with anonymous survey of 525 men with mean age of 64.2+/-9.93 years, living in Moscow and went to the urologist with urinary disorders. All respondents answered questions from specially designed questionnaire consisted from 140 items. All medical data were analyzed, including received drugs, the duration of the therapy and subjective assessment of efficiency. RESULTS: A total of 419 patients from 525 (79.8%) received any kind of therapy. The most commonly used drugs were -blockers, which consisted 65% of all prescriptions. Other drugs were administered significantly rarely. It is surprisingly, that 85.6% of respondents in Moscow region received the original -blockers, not generic drugs. Satisfaction rate was 74.3%. Most of patients (58.3%) had received -blockers for 1-3 years and 33.3% administered these drugs for more than 3 years. Combined drug therapy was the second most popular (25.5%). The most commonly used combination included -blockers and inhibitors of 5-reductase. In 90.6% cases the appointment was made by urologist. CONCLUSION: Drug therapy is the most popular treatment in patients with LUTS. Our data suggest that -blockers as monotherapy or in combination with inhibitors of 5-reductase is the most often prescribed therapy. These results are in concordance with the main conclusions of international studies dedicated to this issue.

[Comparative characteristics of injuries to individual body parts of the driver and passengers inside the passenger compartment of a moving vehicle in a traffic accident]. / Sravnitel'naia kharakteristika povrezhdenii otdel'nykh chastei tela u voditelia i passazhirov vnutri salona dvizhushchegosia avtomobilia pri dorozhno-transportnom proisshestvii.

The purpose of this study was to investigate the general nature of injuries sustained in a moving passenger car during an accident. The study investigated the nature of injuries in drivers (99 cases) and passengers in the front seat (64), rear right seat (15), rear middle seat (29) and rear left seat (22) who died in an accident due to frontal collision with an obstacle. The general characteristics of the resulting damage were determined with regard to their type, quantity and localization. Drivers were found to have predominantly left-sided injuries to the head and chest, as well as right-sided abdominal and pelvic injuries, frequent neck injuries, smaller limb and permanent foot injuries. The injuries sustained by front seat passengers were characterized mainly by right-sided localization of head and neck injuries, maximum left-sided injury of the upper and lower limbs, and an absence of injuries to the feet. Passengers in the rear right seat were predominantly characterized by right-sided localization of injuries to the head, chest, stomach, pelvis and limbs, an absence of injuries to the feet and a relatively high frequency of damage to the internal organs of the thoracic and abdominal cavities. Passengers in the rear middle seat were characterized by uniform distribution of injuries on the left and right sides of the body, a relatively high frequency of injuries to the head, upper limbs, chest, abdomen and pelvis, a relatively low frequency lower limb injuries and an absence of injuries to the feet. Passengers in the left-hand rear seat were characterized by maximum left-sided localization of injuries to the head, chest and left extremities and minimum traumatization of the internal organs of the thoracic and abdominal cavities.

[General characteristics of morphometric and morphoscopic signs of liver rupture with different localizations]. / Obshchaia kharakteristika morfometricheskikh i morfoskopicheskikh priznakov razryvov pecheni razlichnoi lokalizatsii.

The aim of this study was to compare the morphoscopic and morphometric features of local and remote liver ruptures under various external influences. It was found that the local main ruptures were formed in the case of impact trauma more often in the right side of the liver on its diaphragmatic surface, in the anterior third of the organ. They were linear and located in the longitudinal direction. The size of the ruptures increased as the impact force increased. Local additional ruptures were associated with impact and compression trauma and were located only on the diaphragmatic surface of the liver, more often in the right half, in the middle third of the organ. These ruptures were linear, co-directional and small in size under various external influences. Central ruptures were formed by impact and compression trauma, were located more often in the middle third of the right side of the liver and were slit-shaped with a longitudinal direction. The size of central ruptures was associated with falls on the stomach and compression trauma. Peripheral ruptures were formed in the case of impact and compression trauma, were located more often in the right half of the liver on its diaphragmatic surface, mainly in the middle third of the organ and were linear with a slanting direction. The relative constancy of the average sizes of peripheral ruptures was noted. Anti-shock ruptures were observed resulting from shock trauma and were located more often in the right side of the liver, on its visceral surface, in the rear third of the organ. They were linear and curvilinear, and longitudinally and obliquely oriented. Ruptures were relatively constant in size with different types of impact.

[Specific features of lower urinary tract symptoms in men living in the moscow region. Results of the epidemiological study].

INTRODUCTION: Voiding disorders in men are manifested by various symptoms associated with impairment of the urinary flow along the urinary tract and worsening of the urinary bladder storage function. There is a considerable lack of data on the prevalence of LUTS, their severity, and correlation with data from objective studies in men in the Russian Federation in general and in the Moscow region in particular. MATERIALS AND METHODS: A prospective multicenter epidemiological study "Specific Features of Lower Urinary Tract Symptoms in Men Living in the Moscow Region" was conducted based on data acquired from April 1 to May 31, 2017 by an anonymous survey of 525 men (mean age 64.2+/-9.93 years old), residing in Moscow and presenting with complaints of urination disorders. The respondents answered questions of a specially developed 140-item questionnaire. All demographic and medical information was taken into account, including concomitant diseases and ongoing therapy. The patients filled out the IIEF, I-PSS, QoL, and AMS (Aging Male Screening) questionnaires. RESULTS: Analysis the I-PSS scores showed that symptoms of the emptying phase predominated over the symptoms of the filling phase in all age groups. The most frequent complaints were "frequent urination" and "weak urine stream". Forty and 30% of respondents had moderate and severe LUTS, respectively. The remaining 30% of men had mild LUTS. Prostate volume was significantly greater than that reported in similar studies conducted in Asia, Europe and North America (mean 55.27 cm3). The level of total prostate-specific antigen (PSA) was known in 98.8% of patients over the age of 50 and averaged 3.87+/-4.41 ng/ml. The mean age at the first testing for total PSA in Moscow is 56.7+/-9.0 years. CONCLUSION: This study is the first epidemiological study of this scale and focus. Its findings can be used to compose a "portrait" of a standard patient and identify patterns that limit the extrapolation of international epidemiological studies to the population of Russian patients. It seems necessary to develop an updated LUTS management strategy, taking into account the identified national characteristics.

[Forensic medical determination of the age based on the analysis of CT-scanograms of the skull and the craniovertebral region in the sagittal projection]. / Sudebno-meditsinskoe ustanovlenie vozrasta po KT-skanogrammam cherepa i kraniovertebral'noi oblasti v sagittal'noi proektsii.

The objective of the present study was to determine the biological age of the unrecognized individuals based on the analysis of CT-scanograms of the skull and the craniovertebral region in the sagittal projection. We investigated the structure of the spongy substance of the clinoid plate of the sella turcica and the clivus of the cranium, involution of the vertebrae configuration in the medial atlantoaxial articulation, frontal and sphenoidal sinuses. A total of 80 skulls of Caucasoid individuals at the age ranging from 4 to 84 years belonging to an Eastern Slavonic population (free from the pathological lesions in the above cranial structures) were available for the examination. The results of the multifactorial analysis gave evidence of the possibility to estimate the age of individual subjects based on the comprehensive aggregate qualitative and quantitative characteristic in the framework of the linear regression model by making use of the age-related changes in the frontal and sphenoidal sinuses, the sella turcica and the clivus of the cranium, the first and the second cervical vertebrae with an accuracy to within 6 years. It is concluded that the application of the systems for the automated statistical analysis of the images for the purposes of forensic medical expertise would allow to obtain the results of great practical and scientific value.

[COMPARATIVE CHARACTERISTICS OF EPIDEMIC SEASONS OF INFLUENZA 2015-2016AND 2009 -2010].

AIM: Analyze epidemiologic and- clinical features of influenza epidemic seasons 2009 - 2010 and 2015 - 2016. Materials and methods Forms of federal state statistic observation No.4 , 2, 5, and 6; information from the official web-site of the Research Institute of Influenza of the Ministry of Health of Russian Federation; materials of various conferences and congresses on problems of influenza; information-analytical certificates of the Ministry of Health .of Russian Federation. RESULTS: Epidemic morbidity increases in the season 2009 - 2010. and 2015 - 2016 started at various time and had different duration. Children younger than 14 years of age predominated in the structure of patients in the 2009 - 2010 epidemic season, the main mass of patients were presented by individuals aged 45 - 59 years in the 2015 - 2016 season. The number of lethal outcomes with laboratory confirmed influenza diagnosis in 2009 - 2010 was 687-cases, and in 2015 - 2016 - 663 cases. Almost all the deceased from influenza were not vaccinated against this infection. Cardiovascular system diseases were noted in 484 individuals of the total number of deceased. Most of the deceased were late to seek medical aid. CONCLUSION: Influenza epidemic season 2015 - 2016 differs from 2009 - 2010 season by dynamics of morbidity development and a lower amount of severe forms of the disease and lethal outcomes. This may be-due to an increase of population immunity against pandemic strain A(H1N1)pdm09 via pro-epidemizing in the recent years as well as an increase of influenza vaccination coverage.

[Intersphincteric resection for stage I-III low rectal cancer is an oncologically safe alternative to extralevator abdomino-perineal rectal resection]. / Intersfinkternaia rezektsiia pri nizhneampuliarnom rake priamoi kishki I-III stadii iavliaetsia onkologicheski bezopasnoi al'ternativoi ékstralevatornoi ékstirpatsii priamoi kishki.

AIM: To compare oncologic efficiency of intersphincteric resections and extralevator abdominoperineal excisions in surgical treatment of low rectal cancer. METHODS: Between 2006 and 2015 in Department of colorectal and pelvic floor surgery (Russian scientific center of surgery n.a. acad. B.V. Petrovsky) and in Clinic of Colorectal and Minimally invasive surgery (Sechenov First Moscow State Medical University) 40 consecutive patients underwent intersphincteric resection (ISR) and 31 underwent extralevator abdominoperineal excision (EAPE). All patients had low rectal cancer staged I-III within 5 cm from the anal verge. RESULTS: Circular resection margin >1 mm was achieved in 95% and 84% of patients after ISR and EAPR correspondingly (p=0.002), negative distal resection margin was achieved in 95% of ISR patients. In ISR group mean distance from the lower tumor edge to the distal resection margin was 1,17±0,78 cm. Colo-anal anastomosis leak rate was 17%. The 3-year disease-free survival in ISR group was 97%, 5-year disease-free survival was 93%. The 5-year disease-free survival in stage III for ISR group was 71,4%. In 98% of ISR patients complete restoration of bowel continuity was performed.

[Growth disorders after treatment for acute lymphoblastic leukemia in childhood].

AIM: To evaluate the character of growth disorders and risk factors of their development after treatment of acute lympho- blastic leukemia (ALL) patients in childhood. MATERIALS AND METHODS: In this study 25 patients (16 women and 9 men) who had undergone treatment for ALL in childhood were assessed. Patients underwent polychemo- therapy and cranial irradiation. Average age at the time of the survey - 21,2±3,9 years; average age at the time of treatment - 6,9±3,4 years; average follow-up - 13,8±4,9 years. Healthy volunteers were included in the control group (10 women and 6 men) at the age of 25,9±3,6 years. Patients' anthropometric and laboratory parameters were measured. RESULTS: SDS of the final height in ALL survivors was significantly lower in comparison with the control group (p=0,009). ALL survivors had significantly higher difference between final and target height compared to control (p=0,049). 4 of 8 men (50,0% CI: 24,5% - 75,5%) and 13 of 15 women (86,7% CI:68,1-95,7%) have reached the target height. 73,9% (CI: 56,3% - 86,8%) of ALL survivors have reached target height which is significantly lower than in the control group (p<0,001). We found a significant backward correlation be- tween the age at the time of treatment and reaching of the target height (r=-0,415, p=0,049). ALL survivors also suffered from obesity - 12%, dyslipidemia - 36,8%, insulin resistance - 66,7%. CONCLUSION: Treatment for ALL in childhood causes a de- crease of final height. Its main risk factor is the age at the time of the treatment. ALL survivors are diagnosed with the other endocrine disorders and they need an endocrinologist's observation.

[ASSESSMENT OF THE RISK OF INCIDENTAL PROSTATE CANCER PROGRESSION].

At present, methodology based on the stage T1a or T1b is used to determine the risk of incidental prostate cancer (IPC) progression. This approach was developed before the introduction of prostate-specific antigen (PSA) into the practice of the urologist, and does not account of the degree of IPC. For the prediction of IPC progression, multifactorial prognostic model was created. This model is based on the analysis of two parameters--the total PSA level before the surgery and the Gleason score according to the results of morphological examination after transurethral resection of the prostate hyperplasia. This model has a high predictive value (AUC 86.6%) and can be easily used in practice. For the interpretation of the calculated results special table is formed that allows to assess the risk of progression over the next 3.5 years.

AIM: to estimate the prevalence of newly-diagnosed chronic kidney disease (CKD) and its risk factors in patients of a therapeutic clinic, to evaluate the importance of GFR calculation using the CKD-EPI formula. Materials and methods: the study included 275 patients (275 (31.1%) men and 610 (68.9%) women) aged 18-89 (mean 59.5 13.95) years. GFR of 60ml/min/l.73 m3 or signs of kidney lesions were diagnosed as CKD. Possible risk factors of CKD were elucidated based on the results of a questionnaire that provided information on complaints, metabolic disorders, family histoty compliance with a healthy lifestyle. Arterial pressure and serum creatinine level were measured, BMI and GFR calculated in all patients. RESULTS: Medical histories of 58% of the 885 patients contained signs of CKD. Among the remaining 372 (42%) ones, 7.2% had proteinuria and 20.1% GFR of 60ml/min/1. 73/m3. The prevalence of newly diagnosed CKD was 27.3%. The use of the CKD-EPI formula allowed to diagnose CKD in 18% of the patients having the serum creatinine level within normal values. The overall prevalence of CKD in the study group was 14%. CONCLUSION: the prevalence of newly diagnosed CKD in patients of a therapeutic clinic was 2 7.3%. The use of the CKD-EPI formula facilitates diagnostics of CKD.
