[Treatment of toxic hepatitis in COVID-19 patients].

BACKGROUND: The article reflects the clinical significance of the early diagnosis of toxic hepatitis in patients who have undergone a new coronavirus infection with the determination of clinical and laboratory predictors of the response to therapy. A dynamic analysis of the effectiveness of toxic hepatitis therapy in patients of three experimental groups and a control group is presented. AIM: The aim of the present study is to increase the effectiveness of the treatment of toxic hepatitis in patients who have undergone COVID-19. MATERIALS AND METHODS: On the basis of the newly created infection centers of the Central Clinical Hospital "RZhD-Medicine" and Vishnevsky 3-rd Central Military Clinical Hospital 996 patients with COVID-19, who had clinical and laboratory signs of toxic liver damage (cytolytic and/or cholestatic syndromes) against the background of COVID-19 therapy. RESULTS: On the 14th day from the start of therapy in group 3, there was a significant decrease in the clinical manifestations of jaundice in 163 (72.8%) patients, on the 21st day of treatment, this symptom was stopped in all patients. In groups 1 and 2, the decrease in clinical manifestations of jaundice was significantly lower - 122 (55.2%) and 134 (58.8%); p<0.05. At the end of therapy, no manifestations of jaundice were observed in all experimental groups, while in the control group, symptom reduction was achieved only in 47 (14.5%) patients. CONCLUSION: The use of drugs with hepatoprotective effect in the form of monotherapy in groups 1 (UDCA) and 2 (ademethionine) showed a low therapeutic effect with positive dynamics of clinical and laboratory indicators of toxic hepatitis activity. The use of combined treatment in group 3 (UDCA and ademethionine) demonstrated the maximum therapeutic effect, pronounced positive dynamics in the form of normalization of clinical and laboratory indicators of toxic hepatitis activity.

[Composition of oropharyngeal microbiota in patients with COVID-19 of different pneumonia severity].

AIM: To identify features of the taxonomic composition of the oropharyngeal microbiota of COVID-19 patients with different disease severity. MATERIALS AND METHODS: The study group included 156 patients hospitalized with confirmed diagnosis of COVID-19 in the clinical medical center of Yevdokimov Moscow State University of Medicine and Dentistry between April and June 2021. There were 77 patients with mild pneumonia according to CT (CT1) and 79 patients with moderate to severe pneumonia (CT2 and CT3). Oropharyngeal swabs were taken when the patient was admitted to the hospital. Total DNA was isolated from the samples, then V3V4 regions of the 16s rRNA gene were amplified, followed by sequencing using Illumina HiSeq 2500 platform. DADA2 algorithm was used to obtain amplicon sequence variants (ASV). RESULTS: When comparing the microbial composition of the oropharynx of the patients with different forms of pneumonia, we have identified ASVs associated with the development of both mild and severe pneumonia outside hospital treatment. Based on the results obtained, ASVs associated with a lower degree of lung damage belong predominantly to the class of Gram-negative Firmicutes (Negativicutes), to various classes of Proteobacteria, as well as to the order Fusobacteria. In turn, ASVs associated with a greater degree of lung damage belong predominantly to Gram-positive classes of Firmicutes Bacilli and Clostridia. While being hospitalized, patients with severe pneumonia demonstrated negative disease dynamics during treatment significantly more often. CONCLUSION: We have observed differences in the taxonomic composition of the oropharyngeal microbiota in patients with different forms of pneumonia developed outside hospital treatment against COVID-19. Such differences might be due to the presumed barrier function of the oropharyngeal microbiota, which reduces the risk of virus titer increase.

[Prevalence and prognostic value of gastroenterological manifestations of COVID-19: data from the Russian University Clinic].

AIM: Assessment of the prevalence and prognostic value of gastroenterological manifestations in patients with COVID-19. MATERIALS AND METHODS: A single-center retrospective cohort study was carried out. Only cases with laboratory confirmed detection of SARS-CoV-2 virus RNA using polymerase chain reaction in oro-/nasopharyngeal smear samples were subject to analysis. Patients with documented (according to anamnestic data and/or according to examination data during hospitalization) organic pathology of the gastrointestinal tract (GIT) and/or hepatobiliary system, malignant neoplasms of any localization, as well as pregnant patients were excluded from the general register of retrospective data. The final cohort was divided into two groups depending on the presence of gastrointestinal symptoms: COVID-19 with gastrointestinal symptoms (cases) and COVID-19 without gastrointestinal symptoms (control). RESULTS: The final sample consisted of 3764 patients, including 2108 (56%) women and 1656 (44%) men. The average age of the subjects included in the analysis was 58.0 years (95% confidence interval CI 48.663.0). In the study cohort, gastroenterological manifestations (alone or in combination) were recorded in 885 (23.51%) patients. Calculation of the odds ratio (OR) of unfavorable and lethal outcomes between the analyzed groups showed that the presence of gastroenterological symptoms significantly increases the chances of lethal outcome in a cohort of elderly and senile patients (OR 1.6817, 95% CI 1.03352.7364; p=0.0364), determines a higher risk of hospitalization or transfer to the intensive care unit (OR 1.2959, 95% CI 1.05471.5922; p=0.0136), development of acute respiratory distress syndrome (OR 1.5952, 95% CI 1.31641.9329; p0.0001), as well as the need for mechanical ventilation (OR 1.2849, 95% CI 1.0771.5329; p=0.0054). CONCLUSION: The present study has demonstrated that gastroenterological symptoms are detected in about one in four patients infected with the SARS-CoV-2 virus and multiply the risk of adverse and life-threatening complications of COVID-19.

[Diagnostics and treatment of non-alcoholic fatty liver disease with concomitant asthenic syndrome].

AIM: Analysis of the effectiveness of therapy for non-alcoholic fatty liver disease (NAFLD) with severe asthenic syndrome. MATERIALS AND METHODS: In the period from 2017 to 2019, on the basis of the gastroenterology center of the Vishnevsky 3-rd Central Military Clinical Hospital, 247 patients with NAFLD, including those at the stage of steatohepatitis, and severe asthenic syndrome were examined and treated. The main group included 124 patients, the control group 123 patients. All patients underwent complex laboratory and instrumental diagnostics and neuropsychological research using the subjective asthenia assessment scale (MFI-20). In both groups, domestic drugs were included in the therapy regimen: from the 1st to the 10th day, Heptrong solution 3 ml intramuscularly in the morning; from the 1st to the 60th day UDCA 250 mg orally, 3 capsules at bedtime, Omega-3 forte 1000 mg, 2 capsules in the morning with meals. In group I patients received additionally from the 1st to the 10th day intravenous drip Cytoflavin 10 ml + 0.9% NaCl solution 200 ml; pentoxifylline solution 5 ml + 0.9% NaCl solution 200 ml. Then, from the 11th to the 60th day, Cytoflavin inside, 2 tablets 2 times a day. Pentoxifylline inside 400 mg 1 tablet 3 times a day. All patients underwent neuropsychological examination using the subjective asthenia rating scale (MFI-20). RESULTS: The effectiveness of treatment in patients of both groups was assessed by clinical, laboratory data and neuropsychological studies. In the main group, a significant reduction in asthenic syndrome was achieved against the background of diagnosed NAFLD compared with the control group. CONCLUSION: The early inclusion of patients with NAFLD and severe asthenic syndrome in the treatment regimen, in addition to the basic therapy of Cytoflavin, achieved a significantly high therapeutic effect in the form of normalization of the main clinical, laboratory and instrumental parameters, as well as a significant reduction in the manifestations of asthenia.

[Optical coherence tomography and optical coherence tomography-angiography in the diagnosis of chiasmo-sellar region compression]. / Opticheskaya kogerentnaya tomografiya i opticheskaya kogerentnaya tomografiya-angiografiya v diagnostike kompressii khiazmal'no-sellyarnoi oblasti.

Preservation of visual functions in patients with chiasmo-sellar region compression (CSRC) is possible with early diagnosis and surgical decompression. PURPOSE: To analyze the parameters of optical coherence tomography (OCT) and optical coherence tomography-angiography (OCTA) in patients with CSRC. MATERIAL AND METHODS: The study included 10 patients (20 eyes) with CSRC, 15 healthy volunteers (30 eyes). OCT, OCTA was performed on Cirrus HD-OCT 5000 AngioPlex™ (Carl Zeiss Meditec, U.S.A.) with AngioVue system. RESULTS: Patients with CSRC were revealed to have decreased thickness of ILM-RPE in the nasal sector of outer circle (p<0.001) and average mGCIPL - total and for all six sectors (p<0.001), decreased RNFL in the inferior sector (p=0.017); decreased superficial vessel density (SVD) and perfusion density in the inner and outer circle areas and in all sectors of the ETDRS grid (p<0.001) except temporal; in the peripapillary area, decreased vessel perfusion density (VPD) in the inferior sector (p=0.025), capillary flux index (CFI) in all sectors (p<0.001; p=0.025 in the inferior sector). Informative diagnostic criteria included ILM-RPE in nasal sector of the outer circle (AUC=0.896); mGCIPL in the inferonasal sector (AUC=0.914), average (AUC=0.846), superior (AUC=0.829) and superonasal (AUC=0.846) sectors; average SVD (AUC=0.805) and SVD in the inner circle area (AUC=0.810); CFI in the inferior sector (AUC=0.806) with p<0.001. CONCLUSION: In CSRC, changes can be seen in OCT and OCTA parameters recorded in the macular and peripapillary regions before the changes in the central visual field. Informative diagnostic OCT and OCTA criteria can help diagnose the pathology early, expand the indications for decompression, and preserve the visual funcitons.

[Clinical efficacy of neurometabolic therapy of dissomical disorders in asthenic syndrome]. / Klinicheskaia éffektivnost' neirometabolicheskoi terapii dissomnicheskikh rasstroistv pri astenicheskom sindrome.

AIM: To analyze the efficacy of cytoflavin in the complex treatment of sleep disorders in asthenic syndrome. MATERIAL AND METHODS: One hundred patients with sleep disorders and asthenic syndrome of various etiology and severity were studied. The patients were divided into three groups depending on the type of therapy: the first group received intravenous infusions of cytoflavin for 10 days; the second group, in addition to cytoflavin, received per os melatonin (3 mg or 5 mg) at bedtime; the third group in addition to cytoflavin received per os zopiclone (7.5 mg) at bedtime. RESULTS: On the 14th day of the study, a decrease in severity or complete relief of asthenia manifestations (according to the SHAS scale) and, accordingly, improvement or normalization of sleep in 97% of patients was found. At the same time, during polysomnographic study, the data obtained are characteristic for improving the quality of sleep phases mainly in the first and second groups of patients and, to a lesser extent, in the third group. CONCLUSION: Cytoflavin effectively suppresses the main manifestations of asthenic syndrome, including sleep disorders.

[Massive parallel sequencing for molecular-genetic diagnosis of mental retardation]. / Massovoe parallel'noe sekvenirovanie v molekuliarno-geneticheskoi diagnostike umstvennoi otstalosti.

Gene mutations occur with high frequency in children with mental retardation. Standard diagnostic methods, such as TMS, Sanger's sequencing of individual genes, MLPA analysis of deletions, and investigation of methylation status in Martin-Bell syndrome are not informative in the majority of cases that hampered further diagnostic efforts. Massive parallel sequencing (MPS) allowed physicians to continue diagnostic search in previously undiagnosed cases and to find molecular causes of disease. MPS permits to discover a large number of new genes and understand the pathogenesis of mental retardation and brain development more deeply. It became possible to perform prenatal and pre-implantation diagnostics. However, big data generate big problems with their interpretation the genetic counselor faces with. This review reflects the advantages and disadvantages of MPS. Different variants of MPS, including gene panels, whole exome and whole genome sequencing as well as sequencing of trios, are described. In addition, the authors discuss the difficulties of interpretation of the results and recommendations for obtaining the most accurate results.

Wound analgesia in a patient with hemophilia in a highly traumatic operation.

AIM: The aim of the study was to describe the use of the wound analgesia method in a patient with hemophilia in the case of a clinical case. MATERIALS AND METHODS: A patient with severe hemophilia A underwent postoperative analgesia after total knee replacement (within the first 48 hours) with an extended infusion of local anesthetic (ropivacaine) into the wound. RESULTS: During the first 8 hours, the patient received 20 mg of morphine (with the aid of a device for patient-controlled analgesia), the pain level ranged from 7 to 4 points. Further, there was a sufficient effect (NRS - 2 points), from anesthesia only with ropivacaine, using a system for anesthetizing surgical wounds. Complications and side effects were not noted. CONCLUSION: The clinical case demonstrates an effective and safe method of prolonged analgesia in patients with hemophilia. Considering encouraging data, further study of wound analgesia in this category of patients is necessary.

Randomised non-inferiority trial: 1600 mg versus 400 mg tablets of mesalazine for the treatment of mild-to-moderate ulcerative colitis.

BACKGROUND: High concentration mesalazine formulations are more convenient than conventional low concentration formulations for the treatment of ulcerative colitis (UC). AIM: To compare the efficacy and safety of 1600 mg and 400 mg tablet mesalazine formulations. METHODS: Patients with mild-to-moderate active UC (Mayo Clinic Score >5; N=817) were randomised to 3.2 g of oral mesalazine, administered as two 1600 mg tablets once, or four 400 mg tablets twice daily. We hypothesised that treatment with the 1600 mg tablet was non-inferior (within a 10% margin) to the 400 mg tablet for induction of clinical and endoscopic remission at week 8. Open-label treatment with the 1600 mg tablet continued for 26-30 weeks based on induction response. Predictors of treatment response were also explored. RESULTS: At week 8, remission occurred in 22.4% and 24.6% of patients receiving the 1600 mg and 400 mg tablets, respectively (absolute difference -2.2%, 95% CI: -8.1% to 3.8%, non-inferiority P=.005). Endoscopic and histopathologic disease activity, leucocyte concentration and age were significantly associated with clinical remission (P=.022, .042, .014 and .023, respectively). At week 38, 43.9% (296/675) of patients who continued treatment with the 1600 mg formulation were in remission, including 70.3% (142/202) of patients who received a reduced dose of mesalazine (1.6 g/d). The overall incidence of serious adverse events was low. CONCLUSIONS: Induction therapy with 3.2 mg mesalazine using two 1600 mg tablets once-daily was statistically and clinically non-inferior to a twice-daily regimen using four 400 mg tablets (NCT01903252).

[The specific features of pain syndrome in patients with hemophilia]. / Osobennosti bolevogo sindroma u patsientov s gemofiliei.

AIM: to study the nature of pain in hemophilic arthropathy and its prevention ways used by patients with hemophilia. SUBJECTS AND METHODS: A prospective, multicenter, cross-sectional study was conducted to interview 136 patients with hemophilia A or B. The survey included 32 points, including questions about drug and nondrug pain treatment, as well as questionnaires to assess the severity of pain and its impact on daily life (Brief Pain Inventory) and those to identify a neuropathic pain component (PainDetect questionnaire). RESULTS: 83 (75%) patients with hemophilia experienced acute pain associated with bleeding into the large joints; 44 (39%) patients had chronic pain that had lasted longer than six months; 33% assessed the moderate pain experienced in the past 24 hours as severe (more than 5-8 of the 10 scores). In addition to the above, only 32% of the respondents indicated that they had painless intervals within the last 24 hours. 75% of the hemophilia patients mentioned to have limited daily activities. 74% reported their partial or complete disability when pain occurred. 77% of the respondents pointed out that when having pain, they had experienced great difficulty walking. 55% of the hemophilia patients had sleep disorders because of pain. When acute pain occurred, only 91 (81%) respondents injected a factor VIII or IX preparation, 37% of the respondents used narcotic analgesics; 51% received different nonsteroidal anti-inflammatory drugs; 13% took paracetamol. Some patients indicated that they used alcohol and illegal narcotic drugs to relieve pain. Attention is drawn to the fact that the hemophilia patients very frequently took painkillers: 60% of the respondents used analgesics every month; of them 49% had them every week, 11% every day. Most patients (n=83 (74%)) stated that they treated pain (prescribed drugs) themselves; 49 (44%) patients held they were dissatisfied with their pain treatment. When the question as to how the analgesic you used could "remove' pain was asked, only 12 (10%) patients answered that this could fully relieve the pain; 31 (26%) patients told that the pain was not reduced even by half. The study has shown that a neuropathic pain component is very common in hemophilia patients (31%). CONCLUSION: Pain in patients with hemophilia is a serious problem that negatively affects their quality of life, including their working capacity. The prevention and treatment of pain in hemophilia patients should involve the following: organization of educational activities and pain services; adequate treatment of acute pain; detection and prevention of a neuropathic pain component.

[Evaluation of the efficiency of hepatoprotective monotherapy using succinic acid and methionine for nonalcoholic fatty liver disease at the stage of steatohepatitis].

AIM: To evaluate the efficiency of Remaxol monotherapy in patients with nonalcoholic fatty liver disease (NAFLD) at the stage of steatohepatitis (SH). MATERIALS AND METHODS: The treatment of 156 patients with NAFLD at the stage of SH was analyzed. A study group included 84 patients who had received intravenous Remaxol, 400 ml, dropwise at a rate of 40-60 drops per minute once daily in the morning for 10 days; a control group of 72 patients had been treated with the conventional scheme. RESULTS: During the treatment, the study group showed a rapider relief of the manifestations of asthenovegetative and dyspeptic syndromes and a reduction in the magnitude of biochemical manifestations of cytolytic and cholestatic syndromes than did the control group. CONCLUSION: Incorporation of Remaxol into the therapy regimen in patients with NAFLD at the stage of SH enhances the effectiveness of treatment.

[Transcranial dopplerography in the combination with echopulsography in the assessment of intracranial and cerebral perfusion pressure in patients with intracranial hemorrhages].

OBJECTIVE: To study the possibilities of common ultrasound diagnostic methods in the evaluation of intracranial pressure (ICP) and central perfusion pressure (CPP) and to search for the ways of increasing the accuracy of these methods. MATERIAL AND METHODS: Thirty-eight patients, aged 28-66 years admitted to a neuroreanimation department of a hospital due to acute intracranial vascular and traumatic hemorrhages were examined. An instrumental study included transcranial dopplerography (TCDG) and digital echoencephalography. Accuracy of measurement was evaluated for ICP and CPP in clinical conditions. RESULTS: The data obtained confirm the possibility of quantitative assessment of ICP and CPP using TCDG. We suggest a new formula for more precise calculation of CPP. CONCLUSION: The complex use of noninvasive ultrasound methods allow in most cases to measure with acceptable accuracy and assess the degree of intensity of ICP and CPP changes at the acute stage of intracranial hemorrhages.

[Analgesia in hemophiliac patients during orthopedic surgery].

AIM: To develop an effective and safe analgesic regimen (by minimizing the proportion of narcotic analgesics) in hemophiliac patients in the perioperative period during high-trauma surgeries (total knee and hip replacements). SUBJECTS AND METHODS: The prospective study included 24 patients aged 22 to 57 years (median age 38 years) with severe congenital hemophilia A (n = 22) and B (n = 2), who had undergone knee (n = 18) or hip (n = 6) replacements in the Hematology Research Center, Russian Ministry of Health of the Russian Federation, in 2013. Two analgesic regimens (a) paracetamol with trimeperidine; b) paracetamol and ketamine with trimeperidine) were used. To assess pain intensity, the authors used scoring scales: a visual analogue scale (VAS) and a numeric rating scale (NRS). The effect of paracetamol on hemostasis was evaluated on the basis of thromboelastogram and coagulogram readings. Possible paracetamol hepatotoxicity was assessed analyzing liver enzymes. RESULTS: An interview has shown that 66% of the hemophiliac patients regularly take analgesics for chronic pain syndrome, among them 29% use narcotic analgesics. It is difficult to achieve perioperative analgesia in these patients. The dosage of narcotics can be decreased (that of trimeperidine on an average from 80 to 45 mg/day) in the early postoperative period if non-narcotic analgesics, such as paracetamol 4 g/day, are incorporated into the analgesic regimen. Paracetamol promotes pain relief to moderate and mild (not more than 40-50 VAS scores and 3-4 NRS scores), without affecting hemostasis (the thromboelastogram readings differed statistically insignificantly; the coagulation index was 0.6-1.6) and without having a hepatotoxic effect. CONCLUSION: The systemic use of analgesics in hemophiliac patients considerably makes postoperative analgesia difficult. The use of paracetamol with trimeperidine within the first 24 hours after high-trauma surgeries in hemophiliac patients (even if they have hepatitis C) is rather effective and safe.

[Surgical reconstruction of posttraumatic defects and deformities of the orbit using frameless navigation].

PURPOSE: To explore the possibilities of frameless navigation surgery in patients with posttraumatic defects and deformities of the orbit. MATERIAL AND METHODS: In order to develop frameless navigation technique for surgical treatment of posttraumatic defects and deformities of the orbit, examination and surgery were performed on 21 patients of the N.V. Sklifosovsky Research Institute of Emergency Medicine. Multi-slice spiral computed tomography was used for preoperative simulation and intraoperative control. Virtual layer-by-layer reconstruction of missing bone fragments and modeling of anatomical position of dislocated bone fragments in frontal, axial, and sagittal images were performed. Implant position control was done with pointer device of the navigation system. RESULTS: Good functional (disappearance of diplopia in primary position of gaze) and cosmetic results were obtained in all patients. None developed complications in the postoperative period. CONCLUSIONS: The use of frameless navigation in surgical treatment of posttraumatic defects and deformities of the orbit allows to obtain good and stable functional and cosmetic results.

[Pain treatment in patients with hemophilia].

Pain in patients with hemophilia is an urgent problem. The possibilities of using analgesic drugs are interesting by virtue of the specific features of pain syndrome and the problems of treatment in these patients. Foreign and Russian trials using current analgesics are analyzed; difficulties in choosing analgesic therapy and in performing anesthesia mode in patients with congenital hypocoagulation and hyperalgesia are discussed.

[Thrombocytopenia and postoperative analgesia].

OBJECTIVE: To develop effective and safe measures of postoperative multimodal analgesia (optimizing the use of narcotic analgesics) in surgical treatment of hematological patients with thrombocytopenia. DESIGN: A pilot and prospective comparative controlled study. METHODS: We studied 27 patients with acquired thrombocytopenia who underwent laparoscopic splenectomy. Three schemes of anesthesia were used: 1) Nefopam 20 mg/day + trimeperidin (n = 7); 2) Paracetamol 4 g/day + trimeperidin (n = 10); 3) paracetamol + trimeperidin + glucocorticosteroids (GC) (through treatment of the underlying disease) (n = 10). Analgesic properties and effect of each scheme were assessed according to a rating scale of pain NRS (10 points) and VAS (100 points) studied. Additionally we evaluated the effect of nefopam and paracetamol on the functional properties of platelets and hemostasis, platelet levels while monitoring and indicators of thromboelastogram (TEG). RESULTS: Application of paracetamol + trimeperidin accompanied with effectively reducing of postoperative pain (less than 5 points on the NRS). The level of postoperative pain was lower in patients who were treated with corticosteroids within the therapy of the underlying disease before surgery and who continued to receive it in postoperative period (2-3 points NRS). Nefopam use in the perioperative period is not only inferior to the analgesic effect of paracetamol, but also causes frequent side effects. Consumption of narcotic analgesic--trimeperidin when applying nefopam averaged 43 mg/day, the appointment of paracetamol--28 mg/day, using a combination of paracetamol + GC--20 mg/day. Thus, GC within the underlying disease treatment substantially reduces the need for opioid analgesics. A monitoring of the number of platelets and TEG did not shows negative effect of paracetamol and nefopam on platelet and plasma hemostasis. CONCLUSIONS: Nefopam and paracetamol may be used in patients with thrombocytopenia, as do not affect the hemostasis and platelet count. Application of postoperative analgesia scheme paracetamol + trimeperidin in patients receiving corticosteroids provides the maximum reduction of pain with the least consumption of narcotic analgesics.

[Surgical treatment of cranioorbital injuries combined with brain trauma].

Cranioorbital injuries (COI) are combined with brain trauma in 45-53% of patients and in 21--24% of cases require surgical treatment. Aim of this study was to evaluate the results of surgical treatment of patients with COI in acute period of traumatic brain injury (TBI). Among 4078 patients with TBI admitted to neurosurgical department of Sklifosovsky Institute of Emergency Medicine, 428 (10,5%) had COI. In acute period of TBI reconstructive procedures were performed in 158 (36,9%) cases. In 78 (49,4%) patients reconstructive surgical procedures were done within 48 hours after injury, in 35 (22,2%) of them simultaneously with neurosurgical operation. In 53 (33,5%) patients underwent surgical treatment in 1 week after trauma or later. Majority of procedures were reconstructive operations with reposition and rigid fixation of fractured bones using different implants. Overall mortality in patients with COIl was 5,3%, postoperative mortality--4,6%. Postoperatively position of the eyeball was restored totally or partially in 127 (97,7%), oculomotor disorders regressed in 132 (98,5%) patients. Obtained results of surgical treatment of COI in acute period of TBI demonstrate high effectiveness and safety of active surgical tactics. Application of modern diagnostic methods and interdisciplinary approach in management of COI in early period after trauma provide good functional and cosmetic results.

[Plastic closure of anterior fossa with simultaneous reconstruction of superior and middle facial zones].

The article describes surgical treatment of a patient with traumatic brain injury combined with anterior fossa defect, CSF leak, bony fractures of superior and middle facial zones. Multidisciplinary surgical team including neurosurgeon, maxillofacial surgeon and ophthalmologist performed single-step operation which consisted of skull base defect closure, cranialization of frontal sinus and reconstruction of its anterior wall by titanium mesh, reposition and fixation of bony fragments of nasoorbital complex, maxilla, surgical fixation of occlusion by cortical screws. The surgery resulted in cessation of CSF leak, restoration of orbital geometry which lead to regression of diplopia and oculomotor disorders. Cosmetic defect was eliminated. This case report demonstrates high effectiveness of multidisciplinary approach in surgical treatment of complex craniofacial injuries.

[Noncontact impedancemetry for diagnosis of cerebral edema].

An original method of impedancemetry designed by the authors and applied in 88 cases of cerebral edema caused by brain aneurysm rupture (n = 23), by acute hemorragic stroke of hypertensive type (n = 13) and craniocerebral injury (n = 52) is described. Diagnostic value of the method, its safety and convenience for clinical practice are demonstrated.
