[Anatomical and functional results of ossiculoplasty with adjustable length titanium prostheses with and without hydroxyapatite].

Vestn Otorinolaringol 2021 ;86(3):14-19

National Medical Research Center of Otorhinolaryngology, Moscow, Russia.

Objective: To compare the anatomical and functional results of the ossicular chain reconstruction with classic titanium adjustable prostheses and titanium adjustable prostheses with hydroxyapatite cap.

Material And Methods: The 300 patients (360 cases) with chronic suppurative otitis media were examined and operated. The patients are divided into 2 groups. Group A included patients who received an ossicular prosthesis with a hydroxyapatite cap (90 cases with a partial prosthesis and 90 with a full one). Group B included patients who received prostheses without hydroxyapatitis (90 cases with a partial prosthesis and 90 with a complete one). The patients who received a prosthesis with a hydroxyapatite cap were divided into two subgroups, depending on the autotissue, which was placed between the prosthesis cap and the nontympanic membrane: this is an autocartilage plate or perichondrium/fascial graft. The follow-up period after surgery was 38.5±14.4 months (from 12 to 48 months). In the long-term postoperative period, the subjects were assessed the values of the bone-air gap (BAG), the consistency of the nontympanic membrane, and the presence of signs of extrusion of the prosthesis cap. Comparison of anatomical and functional results between patients with full and partial ossicular prostheses was performed separately.

Results: A good result in the form of a 20 dB or more dB BAG reduction was achieved in 82.2% of patients who received a partial prosthesis (85 patients in group A and 63 in group B), and in 57.8% of patients who received a complete prosthesis (45 patients in group A and 59 in group B). The BAG values in the long-term period after surgery did not statistically significantly differ between patients who received a prosthesis with a hydroxyapatite cap or a fully titanium one (=0.939 for patients with full prostheses and =0.745 for patients with partial prostheses). The placement of cartilage or perichondrium/fascial graft between the hydroxyapatite prosthesis cap and the nontympanic membrane also did not affect the functional outcome (with full prostheses - =0.651, with partial prostheses - =0.142).

Conclusion: It is possible to use ossicular prostheses with a hydroxyapatite cap without placing an autocartilaginous plate between the nontympanic membrane and the cap of the prosthesis. In the long term period, functional and anatomical results with hydroxyapatite cap prostheses do not differ statistically significantly from those with all-titanium prostheses.

Chest MRI of patients with COVID-19.

Magn Reson Imaging 2021 06 13;79:13-19. Epub 2021 Mar 13.

During the pandemic of novel coronavirus infection (COVID-19), computed tomography (CT) showed its effectiveness in diagnosis of coronavirus infection. However, ionizing radiation during CT studies causes concern for patients who require dynamic observation, as well as for examination of children and young people. For this retrospective study, we included 15 suspected for COVID-19 patients who were hospitalized in April 2020, Russia. There were 4 adults with positive polymerase chain reaction (PCR) test for COVID-19. All patients underwent magnetic resonance imaging (MRI) examinations using MR-LUND PROTOCOL: Single-shot Fast Spin Echo (SSFSE), LAVA 3D and IDEAL 3D, Echo-planar imaging (EPI) diffusion-weighted imaging (DWI) and Fast Spin Echo (FSE) T2 weighted imaging (T2WI). On T2WI changes were identified in 9 (60,0%) patients, on DWI - in 5 (33,3%) patients. In 5 (33,3%) patients lesions of the parenchyma were visualized on T2WI and DWI simultaneously. At the same time, 4 (26.7%) patients had changes in lung tissue only on T2WI. (P(McNemar) = 0,125; OR = 0,00 (95%); kappa = 0,500). In those patients who had CT scan, the changes were comparable to MRI. The results showed that in case of CT is not available, it is advisable to conduct a chest MRI for patients with suspected or confirmed COVID-19. Considering that T2WI is a fluid-sensitive sequence, if imaging for the lung infiltration is required, we can recommend the abbreviated MRI protocol consisting of T2 and T1 WI. These data may be applicable for interpreting other studies, such as thoracic spine MRI, detecting signs of viral pneumonia of asymptomatic patients. MRI can detect features of viral pneumonia.

[Development and practical implementation of organ preservation surgery in case of placenta accreta in patients with a scar on the uterus].

Probl Sotsialnoi Gig Zdravookhranenniiai Istor Med 2019 Aug;27(Special Issue):693-698

Center for Family Planning and Reproduction, Moscow, Russia, 117209.

Comparative analysis of methods for preventing/stopping intraoperative hemorrhage during surgical delivery of patients with placenta accreta (temporary balloon-assisted occlusion of common iliac arteries, internal iliac artery ligation; uterine artery embolization - UAE) has shown that internal iliac artery ligation is not effective. UAE and especially balloon-assisted occlusion of common iliac arteries have demonstrated a significantly greater effect due to the temporary 'devascularization' of the uterine corpus. It has been proved that an innovative surgical technique - a lower segment Caesarean section (LSCS) significantly reduces intraoperative blood loss. The main purpose of an alternative uterus cut - anterior placenta previa preserving and bleeding absence before the child removal - has been achieved within all observations. LSCS has caused a significantly smaller (by 1.6 times) amount of intraoperative blood loss than the corporal one. Another innovative surgical technique is metroplasty. It entails removing placenta accreta areas from the uterus with subsequent restoration of the organ integrity. The authors have proved the necessity of autologous advance blood donation and hemodilution strategy, which was first implemented in Moscow Center for Family Planning and Reproduction, and after 2006 was used in all obstetric institutions in Moscow. This allowed reducing the number of blood donations up to 85% and additionally decreased transfusiological risks which is economically valuable as well. Improvement of diagnostic methods, operating techniques, hemostasis, blood volume redistribution and creating an algorithm on its basis has proved the possibility of implementing an organ-, life, health- and fertility preserving approach in cases of placenta accreta in patients with a scar on the uterus after cesarean section. The introduction of the enhanced principles of patient management with placenta accreta has significantly reduced the number of hysterectomies in Moscow (from 48 in 2007 to 8 in 2016), and during the last 2 years no patient with this complication has had a hysterectomy. 12 out of 85 patients who had deliveries in accordance with the developed algorithm, have realized their subsequent fertility.

[Therapy of perinatal brain injury outcomes: results of a multicenter double-blind placebo-controlled randomized study of tenoten for children (liquid dosage form)].

Zh Nevrol Psikhiatr Im S S Korsakova 2019 ;119(7. Vyp. 2):33-39

Kazan State Medical University, Kazan, Russia.

Objective: To evaluate the efficacy and safety of tenoten for children (a novel liquid pediatric formulation) in the treatment of perinatal brain injury (PBI) outcomes.

Material And Methods: The multicenter double-blind placebo-controlled randomized trial enrolled 184 children (aged 29 days-9 months) with the total score 12-27 according to Djurba-Mastukova scale and the level of physical development 25-75 centiles. Patients were randomized into tenoten (10 drops per day) and placebo groups. Treatment period was 12 weeks ± 5 days. Percentage of patients with ≥4 points improvement according to Djurba-Mastukova scale (responder rate) was used as a primary efficacy endpoint.

Results And Conclusion: Patients in the tenoten group had a significant result on primary efficacy endpoint: 77.5% of participants responded to therapy (p=0.02 vs. placebo). In addition, the safety of tenoten for children in the treatment of PBI outcomes is shown. Tenoten for children (a novel liquid pediatric formulation) has been shown to be an effective medication in treatment of PBI outcomes that helps to achieve therapeutic results with minimal side-effects, good tolerability and the high level of adherence to therapy.

[Prognostic value of uteroplacental circulation impairment in 1st trimester of pregnancy in patients with complicated obstetric history].

Vestn Ross Akad Med Nauk 2013 (7):4-8

Unlabelled: One of the urgent problems of modern obstetrics is the early detection of irregularities in the development of the uteroplacental vessels system in patients with severe disorders in the history.

Aim: To evaluate the predictive value of re-development of obstetric pathology on the basis of the uterine artery Doppler on 11-14 weeks of pregnancy.

Patients And Methods: 410 patients in I trimester of pregnancy were examined with fetal growth restriction, preeclampsia and/or fetal death and/or a history of preterm delivery were. The influence of physical factors and obstetric history on the state of uterine blood flow in the I trimester of pregnancy was studied.

Results: The optimal Doppler indexes was calculated; a high predictive ability of the pulsation index in the uterine arteries with respect to pregnancy complications with early clinical manifestation, severe preeclampsia and combined obstetric complications was detected.

Conclusions: Our data support the possibility of preclinical diagnosis of obstetrical complications in patients with complicated obstetric history.
