Abstract:

AbstractShade effect is a defect of the images very often invisible for human vision perception but may cause difficulties in proper image processing and object detection especially if the aim of the task is to proceed detection and quantitative analysis of the objects. There are several methods in image processing systems or presented in the literature, however some of them introduce unexpected changes in the images, what may interfere the final quantitative analysis. In order to solve this problem, authors proposed a new method for shade correction, which is based on simulation of the image background based on analytical methods which return pixel values representing smooth grey level changes. Comparison of the effects of correction by applying standard methods and the method proposed are presented.

Abstract:

Aiming at the problems of uneven light reflectivity on the spherical surface and high similarity between the stems/calyxes and scars that exist in the detection of surface defects in apples, this paper proposed a defect detection method based on image segmentation and stem/calyx recognition to realize the detection and recognition of surface defects in apples. Preliminary defect segmentation results were obtained by eliminating the interference of light reflection inhomogeneity through adaptive bilateral filtering-based single-scale Retinex (SSR) luminance correction and using adaptive gamma correction to enhance the Retinex reflective layer, and later segmenting the Retinex reflective layer by using a region-growing algorithm. The texture features of apple surface defects under different image processing methods were analyzed based on the gray level co-occurrence matrix, and a support vector machine was introduced for binary classification to differentiate between stems/calyxes and scars. Deploying the proposed defect detection method into the embedded device OpenMV4H7Plus, the accuracy of stem/calyx recognition reached 93.7%, and the accuracy of scar detection reached 94.2%. It has conclusively been shown that the proposed defect detection method can effectively detect apple surface defects in the presence of uneven light reflectivity and stem/calyx interference.

Abstract:

Introduction. A cleft lip is a congenital malformation that may appear as an independent defect or as one of many syndrome features. Primary cleft lip surgical treatment is the only method of treatment to achieve tissue continuity, however it is associated with the inevitable postoperative scar and the emergence of so‑called secondary disorders, which has got a negative impact on psychosocial patient’s development.Aim. Presentation of possibilities of cleft upper lip scar correction paying attention to facial aesthetics.Material and Methods. The literature search was conducted in the English language via the PubMed database and Main Medical Library. The articles regarding cleft upper lip scar correction and care methods were selected.Results. All the methods of postoperative scar management presented in the results proved to be an effective way of cleft scar correction. These methods concern: surgical procedures, mechanical intervention, laser treatment, and medical therapy with using medicines and are dependent on the type of irregularity. These methods allowed to improvement of the aesthetics of the upper lip area and enabled control and prevention of cleft scar hypertrophy.Conclusions. There is no one procedure regarding the care and correction of cleft scars. Postoperative scar management should be adjusted individually to each patient, analyzing the medical case, to get the best possible aesthetic and functional effect.

Abstract:

In this paper, we propose an adaptive defect-correction method for natural convection (NC) equations. A defect-correction method (DCM) is proposed for solving NC equations to overcome the convection dominance problem caused by a high Rayleigh number. To solve the large amount of computation and the discontinuity of the gradient of the numerical solution, we combine a new recovery-type posteriori estimator in view of the gradient recovery and superconvergent theory. The presented reliability and efficiency analysis shows that the true error can be effectively bounded by the recovery-based error estimator. Finally, the stability, accuracy and efficiency of the proposed method are confirmed by several numerical investigations.

Abstract:

Background. Severe fractures of the shin bones are often accompanied by the formation of defects in the tibia, suppuration and soft tissue necrosis. In the case of surgical treatment of fractures, infectious complications reach 3.6-9.1%. One of the methods of treatment of infected defects is resection of the ends of the tibia with shortening. This operation has proven to be effective in the treatment of fresh fractures. The relevance of the work is due to the prospects of using this technique in the treatment of the consequences of fractures with the formation of infected defects of the tibia.Aim of the study. Improving the results of treatment of patients with post-traumatic defects of the tibia complicated by osteomyelitis by performing a shortening resection with simultaneous or sequential correction of the segment length.Material and methods. The results of treatment of 65 patients with diaphyseal post-traumatic tibial defects complicated by osteomyelitis were analysed. They were divided into 2 groups. Group 1 was formed by 31 (47.7%) patients, they underwent shortening resection of the ends of bone fragments in the defect zone with simultaneous lengthening at another level. Group 2 included 34 (52.3%) patients who underwent a shortening resection of the tibia without lengthening. In all cases, the Ilizarov apparatus was used as a fixator.Results. The technique for assessing the size of the true defect of the tibia was optimized taking into account the initial shortening of the segment and the distance between the proximal and distal fragments after resection of their ends. A treatment regimen was developed depending on the level of localization of the tibial defect, and the results of treatment of patients in the compared groups were assessed.Conclusion. Shortening resection is an effective treatment for patients with post-traumatic tibial defects complicated by osteomyelitis. Depending on the level of localization of the defect, it is advisable to carry out treatment according to one of two possible options. When the defect is localized in the upper and middle third of the tibia, shortening resection in an isolated form is shown. If the defect is localized in the lower third of the tibia, it is possible to supplement the shortening resection with an osteotomy in the upper third with Ilizarov lengthening.

Abstract:

Objective. Dysmorphophobis (body dysmorphic disorder, BDD) is a mental disorder characterized by excessive preoccupation with any imaginary or mild physical defect that causes significant discomfort, distress in the social sphere and other important areas of human activity. The aim was to analyze the possibilities of foreign validated methods for detecting body dysmorphic disorder in a Russian-speaking audience. Materials and methods. Two questionnaires have been translated into Russian, BDDQ-DV and DCQ. The survey was carried out in three samples: patients of a somatic hospital (55 women), clients of a plastic surgeon (71 women) and senior students of the Perm State Medical University (31 women). Results. A positive answer to the question about the presence of a defect in appearance was given by the majority of the survey participants. Most of them described in detail those defects of their appearance that bother them. More than half of them think a lot about the defects. A question with a request to describe the "defect" allows the doctor to clarify the indications for its correction. If the medical correction is not indicated, the physician of the somatic profile can refer the patient for psychological correction. Answers regarding the severity of feelings about the defect, about disorders in social and professional life, about how long it takes to think about a defect and attempts to hide it, as well as whether the respondents have previously consulted about it with a doctor, and what were the results of consultation, allow us to suspect the presence of BDD and refer the respondent to a profile specialist. The analysis of internal consistency demonstrated the possibility of using these questionnaires in scientific research (Cronbach's alpha 0.820.84). Conclusions The presented Russian-language versions of the DCQ and BDDQ-DV questionnaires can be recommended for scientific research as a screening tool for detecting body dysmorphic disorder among females of different age groups. However, their implementation in practice requires a deeper adaptation to the Russian-speaking audience.

Abstract:

PURPOSE: To develop a simplified technique for antenatal correction of a meningomyelocele -like defect in fetal sheep to allow direct skin closure. METHODS: A spinal defect was surgically created at 75 days of gestation in the fetuses of 36 pregnant sheep, 23 survived the surgery. At 102 days gestation, the defect was corrected in 14 cases (9 were left untreated). Skin surrounding the defect was dissected below the dermis to permit its edges to be approximated and sutured, without interposing any material to its edges. An interface material intended to protect the neural tissue from skin adhesion was used and the skin defect was completely closed over it. Pregnancy was allowed to continue up to 138 days gestation, the fetuses were submitted to macroscopic and microscopic analysis. RESULTS: The defect was successfully corrected in 90.9% in the experimental group, and spontaneous closure occurred in 22.3% in the control group (p < 0.05). The survival rate after the creation and correction of the defect was 63.4% and 78% respectively. CONCLUSION: This simplified technique was successful in the correction a meningomyelocele-like defect, in the fetal sheep.

Abstract:

Aiming at the influence of uneven illumination on fabric feature extraction and the limitations of traditional frequency-based visual saliency algorithms, we propose a fabric defect detection method based on the combination of illumination correction and visual salient features—(1) Construct a multi-scale side window box (MS-BOX) filter to extract the illumination component of the image, then use the constructed two-dimensional gamma correction function to perform illumination correction on the image in the global angle, and finally enhance the local contrast of the image in the local angle; (2) Use the L0 gradient minimization method to remove the background texture of fabric images and highlight the defects; (3) Represent the fabric image as a quaternion image, where each pixel in the image is represented by a quaternion consisting of color, intensity and edge characteristics. The two-dimensional fractional Fourier transform (2D-FRFT) is used to obtain the saliency map of the quaternion image. Experiments show that our method has a higher overall recall rate for defect detection of star-patterned, box-patterned, and dot-patterned fabrics, and the overall recall-precision effect is better than other existing methods.

Abstract:

AbstractEarly detection and correction of defects are critical in additive manufacturing (AM) to avoid build failures. In this paper, we present a multisensor fusion-based digital twin for in-situ quality monitoring and defect correction in a robotic laser-directed energy deposition process. Multisensor fusion sources consist of an acoustic sensor, an infrared thermal camera, a coaxial vision camera, and a laser line scanner. The key novelty and contribution of this work are to develop a spatiotemporal data fusion method that synchronizes and registers the multisensor features within the part's 3D volume. The fused dataset can be used to predict location-specific quality using machine learning. On-the-fly identification of regions requiring material addition or removal is feasible. Robot toolpath and auto-tuned process parameters are generated for defect correction. In contrast to traditional single-sensor-based monitoring, multisensor fusion allows for a more in-depth understanding of underlying process physics, such as pore formation and laser-material interactions. The proposed methods pave the way for self-adaptation AM with higher efficiency, less waste, and cleaner production.

Abstract:

A root cause is a source of software defect, whose removal decreases or removes the defect. A root cause of software defect is injected into the software by software engineers during the development process. One of the main concerns of the software team leader, such as the project manager, is to determine who injected various root causes of the defects into the software and when these have been injected. In this paper, a cost-benefit scheme is presented, which allows a software team to determine skill weakness and improve team capability. The scheme provides effective in-process feedback based on the causal analysis of software defects. The proposed analysis scheme includes orthogonal root cause definitions, role-based root cause types, and gradational correction actions. In the experiment, the projects of a distributed health-care system are used to verify the efficiency of the proposed scheme. The results show that the root cause ratios (RCR) are 33.8%, 30.6%, 21.9%, 10.7%, and 3.0% in design, implementation, analysis, business and deployment, respectively. The defects in the projects mainly occurred during the design and implementation phases of the projects. Correction activities to enhance the designers’ skills, such as exception handling (40.5%) and DB/data schema (25.0%), are the top priorities that must be addressed by the software team. The findings can help the team leader to determine methods to improve these weaknesses.

Abstract:

The relevance of the study is due to the fact that hypospadias is a congenital defect of the urogenital system in boys. The incidence rate of hypospadias differs in different countries. The main etiological factor of this defect development is a hormonal imbalance of different origin in mothers. Hypospadias can be corrected only surgically. Currently, there are a number of surgical approaches used, but still, the number of complications in the postoperative period remains high. The purpose of the article was to evaluate the outcomes of surgical correction of hypospadias in children observed after different approaches to urethroplasty involving transplanting. The authors performed a search for articles in electronic databases Pub Med, Elsevier, Scopus, Web of Science for the period from 2007 to 2018. The authors reviewed 265 articles dedicated to the correction of hypospadias by the following methods: TIP (tabularized incised plate), Mathieu, GTIP (graft tabularized incised plate) and two-stage Bracka urethroplasty. The most widespread complications mentioned in different studies were fistulas, stenosis of the urethral neo-meatus, and secondary deformation of the penis. Current approaches to surgical correction of hypospadias in children do not provide complete recovery from post-operative complications. Due to this fact, the issues of treatment of hypospadias remain relevant, requiring the development of new approaches to urethroplasty.

Abstract:

Abstract INTRODUCTION Hydroxyapatite cement is both biocompatible and osteoconductive, and it lacks significant toxic or immunogenic properties, making it an ideal substrate for the repair of cranial defects. However, with its putty-like composition, the repair of large cranial defects can be difficult because significant settling occurs as the cement hardens. We describe a technique in which we use hydroxyapatite cement, reinforced with tantalum mesh and titanium miniplates, for the repair of large (>25 cm2) cranial defects. METHODS After the margins of the cranioplasty are delineated, tantalum mesh is placed under the edges of the defect. Titanium miniplate single-hole bars are used to criss-cross the defect and are then secured to the surrounding bone with screws. The mesh is secured to the bars with 28-gauge stainless steel wire. Hydroxyapatite cement is applied in the defect and contoured appropriately. RESULTS We performed nine cranioplasties in eight patients ranging in age from 1.5 to 35 years (mean, 12.2 ± 10.1 yr). The reasons for cranioplasty included cranial defect from prior trauma (n = 4), fibrous dysplasia (n = 2), infected bone flaps (n = 2), and tumor (n = 1). The cranioplasties ranged in size from 40 to 196 cm2(mean, 128.3 ± 56.9 cm2). Follow-up ranged from 2 to 33 months (mean, 11.4 ± 12.8 mo). Two cranioplasty constructs were removed at 1 and 3 months postoperatively owing to infection. CONCLUSION The use of hydroxyapatite cement with mesh and miniplates provides internal structural support and increased stability of the construct. Although this technique provides an excellent cosmetic result and no evidence to date of bony resorption, the rate of infection is alarmingly high in these large constructs.

Abstract:

Track quality instruments use low-cost accelerometers placed on or attached to the floors of operating trains, and these instruments collect substantial amounts of data over short inspection periods. The measurements collected by the instruments are the main data source for track irregularity evaluation. However, considerable measurement bias exists in the vertical and lateral vibration data obtained from such instruments. False positive track vibration defects detected by track quality instruments occur frequently. This results in considerable time and effort being expended needlessly because maintenance workers have to visit the railway track sites to check and review the track vibration defects. Therefore, we propose a model for data-driven bias correction and defect diagnosis for in-service vehicle acceleration measurements based on track degradation characteristics. Substantial amounts of historical track measurement data from different inspection methods were mined extensively to eliminate the false positive detection of track vibration defects and diagnose the causes of track vibration defects. Actual measurement data from the Lanxin Railway were used to validate our proposed model. The success rate achieved in identifying false positive track vibration defects was 84.1%, and that in track vibration defect diagnosis was 75.8%. These high success rates suggest that the proposed model can be of practical use in improving railway track maintenance management.

Abstract:

Introduction: Flat feet is one of the most common posture defects among children and it usually co-occurs with valgus of the heels, which is called pes plano-valgus. There are many diagnostic methods and physiotherapeutic activities that allow for early detection and appropriate correction of the defect. The use of non-surgical methods may allow the child to avoid surgery in the future. Aim and Methods: Review and analysis of the current scientific literature on the diagnosis and physiotherapy of plano-valgus feet in children. Conclusions: In the diagnostic process, there are many static and dynamic methods for the assessment of plano-valgus foot among children. Special devices such as plantoconturograph, podoscope, and pedobarographic mat are used in the diagnosis of feet in children and have proven to be helpful in the detailed analysis of foot defects. However, an extensive range of physiotherapeutic methods allows for comprehensive treatment using not only corrective exercises, but also physical therapy treatments in order to relieve pain and accelerate recovery. Orthopedic appliances, such as supination insoles, also play an important role in the treatment. The best results were seen in the use of comprehensive treatment and multiple terapeutic methods. Early detection and correct diagnosis of foot abnormalities allow for appropriate treatment with the use of a wide range of physiotherapy methods. This increases the chances of restoring normal foot functions among children and reducing pain with other abnormal symptoms.

Abstract:

Aim: To see the efficacy of titanium mesh in orbital floor reconstruction to correct the post-traumatic enophthalmos in orbito-zygomatic complex fractures. Methods: This retrospective study was carried out in the department of Oral and Maxillofacial Surgery, University College of Medicine & Dentistry, University of Lahore, Pakistan from January 2017 to January 2020. All patients who had enophthalmos after orbito-zygomatic fractures and were treated for orbital floor reconstruction with titanium mesh were included in the study. Computer tomography (CT scan) was done to diagnose and measure the orbital floor defect. Pre-operative and post-operative hertalex ophthalmometry was done to measure and compare the enophthalmos. Results: Among the 30 patients, 23 were male and 7 were female. The mean age of the patients was 30±5.80 years. Fourteen patients had right and 16 patients had left side orbitozygomatic complex fracture. The mean orbital floor defect size was 1.72±0.78 cm preoperatively measured by CT scan.

Abstract:

Introduction: The relevance of our research lies in the search for effective ways of speech therapy through the development of speech breathing in the correction of sound reproduction disorders in preschoolers with dysarthria. There are disagreements in science and practice since the theory recognizes the fundamental importance of speech breathing development in correction of the sound productions defect; whereas speech therapists barely use the corrective possibilities of speech breathing in their practice due to the lack of clearly prescribed consistent recommendations of speech therapy working on the production of speech sounds. The article aims to identify the problems of speech breathing development in the correction of sound reproduction in children with dysarthria, to analyze the state of speech breathing skills important for pronouncing phonemes in 5-6 year-old children with dysarthria, to offer consistent recommendations for speech therapy correction of the defects in working on the production of speech sounds. Materials and methods: The following research methods were used: theoretical, anamnestic consisting in the study of the documentation of preschool educational institution, diagnostic method (diagnosis of speech breathing of senior preschoolers with dysarthria) with screening (study of the speech therapy status of senior preschoolers with dysarthria); methods of quantitative and qualitative processing of the results. Results: We studied the medical records of the preschool educational institution for each child and the speech records of the therapist in order to obtain detailed data on the severity of dysarthria, as well as the intellectual and neurological status, hearing condition of the test subjects in the sample. In order to determine the psychorechological status, the speech therapist reports were later correlated with the speech therapy screening and medical records data. We conducted a study of the state of speech breathing in children with moderate dysarthria and with minimal dysarthric disorders. It was found that in cases of moderate dysarthria, the condition of speech breathing and sound production suffers to a greater extent than in cases of minimal dysarthric disorders. It was revealed that children with dysarthria have the state of speech breathing that correlates with the state of sound reproduction: the more pronunciation defects the child has, the lower the level of speech breathing. Detailed consistent recommendations of correctional work on the development of speech breathing in preschoolers with dysarthria, depending on which speech sound is corrected, are presented.

Abstract:

Introduction. Pes calcaneus deformity is a rare pathology in children, which is due to the defect of long flexors of the foot caused by various neurological diseases. The treatment choice is based on the patient’s age, parameters of neuromuscular disorders, and degree of foot deformation. Aim. This study aimed to analyze the results of operative correction of рes calcaneus deformities in children. Material and methods. This analysis of surgical treatment involved 13 patients (21 feet) aged 1.5 to 15 years with рes calcaneus deformities. The different approaches and methods of surgical treatment were described. Children up to 12 years old were released joints of the foot with the elimination of deformation and tendon-muscle transposition with the transfer of functionally preserved muscles in the position of fallen muscle antagonists. Children over 12 years old underwent surgery on the bone apparatus of foot: three-articular arthrodesis or corrective osteotomy of the calcaneus, some cases were supplemented with tendon-muscle transpositions. Results. Treatment results were evaluated based on the radiometric parameters on the system of AOFAS. All treated patients showed improvement in foot stability with reduced deformation; АОFAS at an average of 91.14 points was observed. Conclusion. A record of all causes and strain components with a graded approach eliminates the pes calcaneus deformity in the long-term, despite persistent violation of neuromuscular conduction.

Abstract:

Recent progress has been made in defect detection using methods based on deep learning, but there are still formidable obstacles. Defect images have rich semantic levels and diverse morphological features, and the model is dynamically changing due to ongoing learning. In response to these issues, this article proposes a shunt feature fusion model (ST-YOLO) for steel-defect detection, which uses a split feature network structure and a self-correcting transmission allocation method for training. The network structure is designed to specialize the process of classification and localization tasks for different computing needs. By using the self-correction criteria of adaptive sampling and dynamic label allocation, more sufficiently high-quality samples are utilized to adjust data distribution and optimize the training process. Our model achieved better performance on the NEU-DET datasets and the GC10-DET datasets and was validated to exhibit excellent performance.

Abstract:

Introduction. Acquired heart defect affect people of different ages and lead to permanent disability, so this is important social problem. The single effective way to treat acquired heart defect, which can significantly increase the life expectancy of patients, is surgical correction aimed at eliminating severe hemodynamic disorders. Sternotomy mediates subsequent changes in the biomechanics of respiration, contributes to the appearance of pain in the thoracic region of the spinal column and ribs. In this regard, the possibility of osteopathic diagnosis and correction of such patients in the postoperative period is an actual question.The goal of research — is to investigate the possibility of osteopathic correction in the complex therapy of patients after sternotomy in the connection with the surgical treatment of acquired heart defect.Materials and methods. The study involved 80 patients after surgical treatment of acquired heart defect. Osteopathic diagnosis was performed before and after surgery. Then, the control (patients received standart treatment) and experimental (patients received standart treatment and osteopathic correction) groups were selected using a simple randomization method. The both group included 40 people. There were assessed the fl uid volume in the pleural cavities (as one of the heart failure indicators) using the ultrasound method for the study of pleural cavities, and the pain intensity (using pain verbal-analogue scale) in both groups before starting treatment. Then the osteopathic diagnostics and theassessment of pain intensity and fl uid volume in the pleural cavities were repeated in each group after completion of the treatment. The collected data was processed by the methods of parametric and nonparametric statistics.Results. Patients after median sternotomy connected with surgical treatment of acquired heart defect had characteristic somatic dysfunctions: global rhythmogenic (cardiac and respiratory) and biomechanical disorders, regional biomechanical disorders of the thoracic region, dura mater and pelvic region, local somatic dysfunctions of the sternoclavicular joint, sternum, ribs, mediastinum, pericardium and ligaments of the liver. Osteopathic correction in patients of the experimental group after median sternotomy leads to a statistically significant (p<0,05) in the comparison with the control group decreasing in the detection frequency of global (rhythmogenic respiratory and cardiac) and regional (thoracic and pelvic region) somatic dysfunctions. A statistically significant decrease in the pain severity and fl uid volume in the pleural cavities (p<0,05) was also recorded after the treatment in the experimental group.Conclusion. There was revealed that patients after surgical treatment of acquired heart defect suffered from developed somatic dysfunctions of global, regional and local levels. It was established that osteopathic correction leads to a decrease in the detection frequency of some global and regional somatic dysfunctions, pain severity and fluid volume in the pleural cavities. So the obtained results allowrecommendingthe osteopathic correction as an effective complement to the standard methods of treating patients after surgical treatment of acquired heart defect.

Abstract:

The aim of the review was to summarize information on clinical manifestations, diagnostic features, as well as methods for correction of scar defects after cesarean section (CS) outside pregnancy. Lack of the scar after CS, niche, isthmocele are a myometrium defect in the area of scar after CS, which is most often detected by ultrasound, sonohysterography or magnetic resonance imaging and is manifested by postmenstrual bleeding from the genital tract. In some cases, it can cause menorrhagia, dyspareunia, pelvic pain, infertility, uterine rupture during subsequent pregnancy and childbirth. Conservative therapy or surgical treatment with laparoscopy, laparotomy or vaginal approach is carried out depending on the symptoms, size of the defect, the thickness of the residual myometrium, as well as the womans reproductive plans.

Abstract:

Background: An isthmocele is a myometrial defect in the site of the caesarean scar. In symptomatic women with abnormal uterine bleeding and secondary infertility, surgical correction can be considered. Most authors advocate that when there’s a residual myometrium ≥ 3mm it can be corrected through resectoscopic approach and when < 3mm the treatment should be laparoscopic, eventually guided by diagnostic hysteroscopy. Both these techniques have important limitations; therefore, the authors propose combining both techniques, in the same procedure, in order to overcome them. Objectives: To demonstrate the advantages of a surgical technique for correction of an isthmocele using both resectoscopic and laparoscopic resection. Material and Methods: A stepwise demonstration of the technique with narrated video footage. Main outcome measures: Intraoperative data and outcomes in the patient’s follow-up. Results: One month after the surgery the patient was asymptomatic, reporting a resolution of the uterine abnormal bleeding, and the ultrasound showed a full correction of the isthmocele. Conclusion: A combination of resectoscopic and laparoscopic resection, in correcting bigger isthmoceles, is a good option to fully excise all the ﬁbrotic tissue. Learning Objective: This video aims to demonstrate the beneﬁts of using a technique combining resectoscopic and laparoscopic resection for correcting larger isthmoceles.

Abstract:

Objective: To improve the outcomes of surgical correction of upper limb dysfunction (ULD) using the latissimus dorsi flap (LDF). Methods: ULD occurred in 76 patients with Volkmann's ischemic contracture (VIC), post-traumatic soft tissue defects, and brachial plexitis in 57, 11, and 8 cases, respectively. Out of 57 patients with VIC, in 30 cases, a skin defect was observed along with severe degenerative changes in soft tissues, neurovascular bundles (NVBs) and tendons. Post-traumatic forearm defects (n=11) in 5 cases were accompanied by damage to the NVBs and tendons. In brachial plexitis, isolated injury to the musculocutaneous nerve occurred in 6 patients, and a combination of nerve lesions with radial nerve palsy – in 2 patients. Results: Transposition of LDF to the biceps brachii for the treatment of brachial plexitis, free muscle transplantation for the treatment of VIC and forearm soft tissue defects were performed in 8, 57, and 11 cases, respectively. Active forearm flexion after the muscle flap transposition was noted after 4 weeks. In contrast, after graft transplantation in VIC, the grip function restoration began after 6 months and improved within 1 year and beyond. Conclusion: Using the LDF in surgical correction of post-traumatic ULD allowed restoring the lost functions of the crushing grip and forearm flexion. For the forearm, only free flap transplantation with a relatively long period of limb function recovery is possible. In contrast, the traspositioned LDF to the biceps allows achieving the desired functional outcomes in the shortest possible time. Keywords: Upper limb, latissimus dorsi flap, Volkmann's contracture, soft-tissue defect, brachial plexitis.

Abstract:

Highlights In recent years, congenital heart defects (CHD) have remained the most prevalent diseases in young children. Opinions on the health of children who have undergone cardiac surgery vary: for example, there are data in the literature indicating that speech disorders following cardiac surgery are present in 56% of cases, whereas cognitive disorders are present in 21% of cases. Aim. To study the level of development of receptive and expressive language in primary schoolchildren with septal congenital heart defects before surgical correction. Methods. The prospective study of children (n = 90) with septal congenital heart defects (atrium septal defect, n = 75; ventricle septal defect n = 15) before surgical correction was conducted at the Scientific Research Institute of Complex Issues of Cardiovascular Diseases (Kemerovo). The anamnesis, clinical symptoms, hemodynamics and the level of speech development (receptive and expressive language) were studied.Results. In children with septal heart defects, speech disorders were noted in 82% of cases: 56% of children had common speech disorders, 26% had delayed speech development. Expressive language skills of these children can be often characterized by delayed development, which manifests in the form of articulation disorder, difficulties with grammar syntax and morphology, and pronunciation disorders. There were no statistically significant differences between the level of expressive language and the type of CHD (p = 0.125).Conclusion. Even in the absence of intracardiac hemodynamic disorders in children with septal CHD, detected neurodevelopmental delays at the preoperative period necessitates the implementation of the interdisciplinary approach in the management of children with such pathology.

Abstract:

Despite the fact that the defect has been known for a long time and methods of surgical correction have been developed that allow achieving excellent immediate and long-term results, the tactical issues of stage-by-stage correction of the defect in situations where primary radical correction is impossible due to such reasons as a severe initial condition, low weight of the patient, underdevelopment of the branches of the pulmonary artery (PA) have not yet been fully resolved. In addition to classical Blalock-Taussig intersystem anastomoses, such endovascular techniques of maintaining pulmonary blood flow as stenting of the right ventricular outflow tract (RVOT) and stenting of the patent ductus arteriosus (PDA) are being introduced into clinical practice. These techniques, with all the advantages of minimally invasive technologies in certain clinical and anatomical situations, are not inferior, and in most cases surpass classical surgical techniques.

Abstract:

Iterative solution methods to solve linear systems of equations were originally formulated as basic iteration methods of defect-correction type, commonly referred to as Richardson's iteration method. These methods developed further into various versions of splitting methods, including the successive overrelaxation (SOR) method. Later, immensely important developments included convergence acceleration methods, such as the Chebyshev and conjugate gradient iteration methods and preconditioning methods of various forms. A major strive has been to find methods with a total computational complexity of optimal order, that is, proportional to the degrees of freedom involved in the equation. Methods that have turned out to have been particularly important for the further developments of linear equation solvers are surveyed. Some of them are presented in greater detail.

Abstract:

In binocular vision inspection system, the calibration of detection equipment is the basis to ensure the subsequent detection accuracy. The current calibration methods have the disadvantages of complex calculation, low precision, and poor operability. In order to solve the above problems, the calibration method of binocular camera, the correction method of lens distortion, and the calibration method of projector in the binocular vision system based on surface structured light are studied in this paper. For lens distortion correction, on the basis of analyzing the traditional correction methods, a distortion correction method based on radial basis function neural network is proposed. Using the excellent nonlinear mapping ability of RBF neural network, the distortion correction models of different lenses can be obtained quickly. It overcomes the defect that the traditional correction model cannot adjust adaptively with the type of lens. The experimental results show that the accuracy of the method can meet the requirements of system calibration.

Abstract:

Objective. Tactics of treatment and results of the hypoplasia of the aortic arch correction in newborn babies with complete form of atrio-ventricular septal defect were studied. Маterials and methods. During period from 2011 tо 2019 yrs in 21 patients correction of hypoplasia of aortic arch and atrio-ventricular septal defect were performed. The investigated group consisted of patients with a two-ventricular physiology. The patients, suffering imbalanced form of atrio-ventricular septal defect and with variants of hypoplasia in left parts of the heart, were excluded from the investigation. There were 9 (42.9%) boys and 12 (57.1%) girls. Average age of the patients have constituted (2.3 ± 1.1) mo (from 0.06 до 7.7 mo). Average body mass of the patients have constituted (3.8 ± 1.0) kg (from 2.0 до 5.9 kg). The aortic arch segment was considered a hypoplastic one if a Z-score (Standard Score - standard estimation) shift have constituted lesser than 2.0. Results. Hospital lethality have constituted 14.2%. Three newborn babies died: 2 - after first stage of correction, and 1 - after second stage of correction. All the patients, to whom a one-staged correction was done, have survived. The causes of lethality were not connected with method of the aortic arch reconstruction. While performance of echocardiography before discharge from the hospital the pressure gradient on place of the aortic arch plasty have constituted (13.6 ± 6.8) mm Hg at average. Average follow-up period have constituted (2.6 ± 2.1) yrs (from 2 mo tо 8.1 yr). In late follow-up period lethality was absent. In 2 (9.5%) patients in postoperative period reoperations on aortic arch and mitral valve were performed. Tracheal compression as well as the main bronchi compression, neurological complications in late follow-up period were absent. Conclusion. For the patients, suffering complete form of atrio-ventricular septal defect in conjunction with hypoplasia of aortic arch the staged correction constitutes a more favorable option, owing good immediate and late results. A staged approach in the treatment is indicated for newborn babies, suffering hypoplasia of distal aortic arch and competent atrio-venticular valves or with small regurgitation. Оne-stage correction is indicated in hypoplasia of aortic arch, pronounced regurgitation on common atrio-ventricular valve and pronounced heart failure.

Abstract:

This article presents an experiment carried out on broilers of Arbor Acres cross in an industrial poultry farm. For the experiment, the authors divided the broiler birds into three groups. Poultry of the control group received basic ration; poultry of the 1st experimental group received feed additive at a dose of 1269 g/t feed 5 days before slaughter; poultry of the 2nd experimental group received feed additive at a dose of 1693 g/t feed 5 days before slaughter. Broilers were slaughtered on day 38 of rearing. The following types of defects were recorded during slaughtering: dermatitis, cellulitis; back scratches; splinter hemorrhages, bruises, hematomas, bruises; dislocations, closed and open fractures; poor bleeding; skin tears; under-plucking; the presence of internal organs; over-steaming of the carcass. The authors applied the Ishikawa method, Pareto charts, ABC analysis, and cluster analysis to assess the quality of broiler chicken carcasses. Based on the results of these studies, the authors identified 41.7 % of defects that reduce the quality of poultry carcasses and 58.3 % of critical defects that lead to meat culling. Using clustering methods and ABC analysis, the authors identified the most important category of critical defect, D2C. This defect in poultry occurs during the rearing and processing phase. The application of the stress-corrector reduced the number of D2C defects in the 1st experimental group by 33.3 %; in the 2nd experimental group by 18.2; D2GD in the 2nd experimental group by 22.2 %. Thus, the use of statistical evaluation methods increases the efficiency of industrial control over the quality level of broiler chicken carcasses.

Abstract:

Today, there is no reliable pharmacological correction of dementia, despite its high prevalence worldwide. The clinical presentation of Alzheimer's disease at one or another stage is accompanied by neuropsychiatric disorders (NPDs) in addition to cognitive defect. The intensity and range of NPDs are different. The possibilities of drug therapy for NPDs are demonstrated. The role of akatinol memantine in correcting a number of psychological and behavioral disorders is highlighted. Biological, psychological, social, and environmental factors are identified among those that contribute to or provoke the development of NPDs. Knowledge of the triggers of mental disorders makes it possible to prevent and thereby reduce or eliminate NPDs. Special emphasis is laid on the patient-caregiver relationship. In recent years, non-pharmacological interventions have been increasingly used as priority-line therapy for NPDs. There are data on main methods for non-pharmacological correction and on the efficiency of their application.

Abstract:

Purpose: Articular cartilage defects are a prevalent consequence of femoroacetabular impingement (FAI) in young active patients. In accordance with current guidelines, large chondral lesions of the hip joint over 2 cm2 are recommended to be treated with matrix-associated, autologous chondrocyte transplantation (MACT); however, the conditions in the hip joint are challenging for membrane-based MACT options. Injectable MACT products can solve this problem. The purpose of the trial was to assess clinical and radiological outcomes 24 months after injectable MACT of focal chondral lesions caused by FAI. Methods: We present data of 21 patients with focal cartilage defects of the hip [3.0 ± 1.4 cm2 (mean ± SD)], ICRS Grade III and IV caused by CAM-type impingement, who underwent arthroscopic MACT (NOVOCART® Inject) and FAI correction. The outcome was evaluated with the patient-reported outcome instruments iHOT33 and EQ-5D-5L (index value and VAS), whilst graft morphology was assessed based on the MOCART score over a follow-up period of 24 months. Results: The iHOT33 score increased significantly from 52.9 ± 21.1 (mean ± SD) preoperatively to 85.8 ± 14.8 (mean ± SD; p < 0.0001) 24 months postoperatively. The EQ-5D-5L index value (p = 0.0004) and EQ-5D VAS (p = 0.0006) showed a statistically significant improvement as well. MRI evaluation after 24 months showed successful integration of the implant in all patients with a complete defect filling in 11 of 14 patients. Conclusions: Injectable MACT for the treatment of full-thickness chondral lesions of the hip joint due to FAI in combination with FAI correction improved symptoms, function, and quality of life in the treated cohort. Alongside the treatment of the underlying pathology by the FAI correction, the developed cartilage defect can be successfully repaired by MACT, which is of considerable clinical relevance.

Abstract:

This paper reports on investigations of the air-coupled ultrasonic (ACU) method to detect common defects in solid timber panels made of Chinese fir (Cunninghamia lanceolata (Lamb.) Hook.). The ACU technology is a non-contact method for nondestructive timber testing with quicker scanning rates compared to contact methods. A testbed was set up consisting of commercially available piezo-ceramic ACU transducers and in-house manufactured signal processing circuits. To demonstrate the suitability of the ACU technique, through-transmission measurement results are presented for samples with defects such as knots, wormholes, and cracks. Pulse compression methods (Barker-coded method) were used to improve the power of received signals based on cross-correction algorithms. Results showed defects of timber panels made of Chinese fir can be detected with a thickness of less than 40 mm. Defects larger than 3 mm in diameter could be detected with high precision. Applying the pulse compression method showed better results than using common sine signals as excitation signals since it increased the signal-to-noise ratio, which is especially important for air-coupled measurement of high-attenuation materials like timber materials. The measurement results on reference samples demonstrated that ACU technology is a promising method for timber defect detection, especially for the quality assessment of engineered wood products.

Abstract:

PURPOSE: To study the intraperitoneal use of polyester with collagen and polytetrafluoroethylene meshes in the correction of total ventral wall defects in rats. METHODS: Thirty two rats were evaluated and divided randomly into four groups and underwent laparotomy and preparation of total defects of the abdominal wall. Next, the correction of the defect with the intraperitoneal placement of the chosen mesh was performed. The rats were submitted to euthanasia at 30 and 90 days after surgery. Were analyzed the macroscopic adhesions and microscopic aspects, and applied stress rupture test RESULTS: All animals showed intraperitoneal adhesions in varying degrees, with no statistical significance difference. There was no difference also between groups in the evaluation of stress rupture tests. On the microscopic aspect, the A30 group had less inflammatory reaction and less formation of granulomas and foreign body reaction that the B30 group, with significant difference. CONCLUSIONS: There was no difference in intraperitoneal adhesion and tensile rupture strength among groups. Group B30 presented granulomatous inflammatory reaction at the site of mesh attachment to the wall significantly higher than the A30.
