Authors: Zhurilo Ivan P. , Medvedev Alexey I. , Chernogorov Oleg L.
Published: October 2024

BACKGROUND: Dermoid cysts in the presacral and retrorectal space in children are relatively rare. However, even more rarely, they have clinical manifestations at patient’s early age and so, can be silent for a long time.
CLINICAL CASE DESCRIPTION: The article describes a rare clinical observation — a giant dermoid cyst in the retrorectal space in a 17-year-old girl. The child had a tendency to constipation from her early childhood. Menses started at age 13, painful. During the last year, disorders in her menstrual cycle were noticed. The girl was examined by a gynecologist. Ultrasound examination revealed a cystic formation in the pelvic cavity up to 9 cm in diameter. Non-malignant nature of the process was confirmed by: normal level of cancer markers (α-fetoprotein, β-human chorionic gonadotropin), single node, clearly defined formation capsule, homogeneous nature of its contents, no invasive growth and lesions in the regional lymph nodes. Magnetic resonance imaging with intravenous contrasting defined a true relationship of the cystic formation with other organs and structures of the pelvic cavity. The cystic formation caused deformation of the cervix, vagina, and rectum. The obtained findings allowed to plan surgical intervention correctly. Surgical access-transverse in the coccyx projection up to 10 cm long. The cystic formation was a thin-walled connective tissue capsule with a yellowish content. Due to very large cyst dimensions, first it was opened in a limited area and emptied. Then the capsule was isolated and completely removed. The cyst intimately adhere to rectum, vagina, and cervix walls. Histological conclusion: "Capsule of a dermoid cyst with hemorrhages". The postoperative period was smooth. The patient recovered, all disease manifestations disappeared. She was discharged home in a satisfactory state. Follow-up visits were in 6 and 12 months after surgery. No evidence of possible relapse.
CONCLUSION: There are only few descriptions of such cases in the available literature. Ultrasound and MRI examinations allowed to have a full picture of dermoid cyst position and its connection with other pelvic organs due to which surgeons could develop a correct plan for surgical intervention.

BACKGROUND: To verify a source of obscure gastrointestinal bleeding leading to iron deficiency anemia is a challenging diagnostic problem. Intestinal polyps can be one of such sources. Sporadic juvenile intestinal polyps are extremely rare at the first year of life. The authors present a clinical case which demonstrates endoscopic diagnostics and resection of a jejunum polyp in a 12-month-old child weighing 6.3 kg. We did not find similar publications in literature.
CLINICAL CASE DESCRIPTION: A 12-month-old boy was admitted to our clinic with long-lasting complaints of dark stool and iron deficiency anemia. For the first time, gastrointestinal bleeding symptoms appeared at the age of one month. The child was repeatedly examined, but gastrointestinal bleeding source was not found. The child was prescribed symptomatic therapy for iron deficiency anemia including red blood cell transfusion. At current hospitalization in our clinic an intestinal polyp and transient small intestinal intussusception were suspected at ultrasound examination. The child underwent esophagogastroduodenoscopy, video capsule endoscopy, colonoscopy, laparoscopy. But the source of the bleeding was not found. During the repeated enteroscopy at 40 cm distally to the pylorus a sporadic juvenile jejunum polyp 17×15 mm was found and resected. The postoperative period was uneventful. In 1 month, there were no complaints as for the catamnesis, the child's stool had the usual characteristics, the indicators of "red blood" corresponded to the age norm.
CONCLUSION: A sporadic juvenile jejunal polyp may be a cause of obscure recurrent intestinal bleeding in children. Modern intraluminal endoscopy allows not only to put diagnosis, but also to perform a minimally invasive surgical intervention.
Hypoxic irreversible brain cells damage, associated risk factors and antihypoxants
Authors: Urakov Aleksandr L , Urakova Natalya A. , Shabanov Petr D.
Published: October 2024

It is reported that in the final stage of many diseases the immediate cause of biological death in humans and warm-blooded animals is hypoxic irreversible damage to brain cells. This explains the fact that to prevent biological death in all critical conditions without exception, inhalation with breathing gases containing oxygen has long been successfully used. This is also why oxygenation of the blood is considered one of the main conditions for preserving human life in all critical situations and forms the basis of emergency medical care in the intensive care unit. However, inhalation of oxygen gas and increasing blood oxygen saturation should be carried out as early as possible, and more precisely — before the onset of the stage of hypoxic irreversible damage in brain cells. The fact is that after the onset of irreversible da­mage brain cells die even in the presence of oxygen. In this connection, the mechanisms of adaptation of the organism to oxygen deficiency play a great role for longer preservation of brain cells viability and human life in conditions of hypoxemia. In order to increase resistance to hypoxemia, antihypoxants are traditionally used. But they can preserve the viability of brain cells not always, but only if they are introduced into the body before the onset of hypoxic irreversible damage to brain cells and in the case of unused reserves of adaptation to hypoxemia in the body. Risk factors of hypoxic irreversible damage of brain cells are indicated, among which excessively long duration of hypoxemia and hyperthermia are emphasized. It is shown that the most important circumstance for the development of hypoxic irreversible damage of brain cells is not so much the degree of hypoxemia as the degree of hypoxia of brain tissue and its duration, which exceeds the period of human resistance to hypoxia. It has been shown that human resistance to hypoxia can be assessed using the Stange test. It has been reported that fever and local cerebral hyperthermia decrease, and hibernation and local cerebral hypothermia increase, the resistance of brain cells to hypoxia. In this regard, recommendations not only to eliminate fever and local inflammatory processes in the head, but also recommendations to reduce brain temperature are highly appropriate to improve resistance to hypoxia. It is pointed out that among the methods of local therapeutic hypothermia, targeted temperature management is the most advanced. In addition, it is reported that in recent years a new group of promising antihypoxants — alkaline solutions of hydrogen peroxide — has been created. It is shown that hydrogen peroxide is able to decompose very quickly into water and oxygen gas under the action of catalase, which is found in all tissues. The peculiarities of using alkaline solutions of hydrogen peroxide as antihypoxants we all have to study in the future.
Arquitetura de capa dos folhetos de cordel
Authors: Da Silva Rodrigo Nunes , Rodrigues Linduarte Pereira
Published: October 2024

Amplamente conhecidos no Brasil, os folhetos de cordel têm produção ativa no Nordeste e caracterizam uma memória de grupo. Por essa razão, este artigo enfatiza a ideia de que esse gênero textual se manifesta e propaga-se pelo viés histórico-discursivo, apoiado por uma tradição oral e a partir de um modelo prototípico delineado. Conforme Rodrigues (2011), texto é produto de interação (comunicação e socialização) humana e extrapola aspectos meramente verbais, envolvendo elementos exteriores, e que são condizentes com o universo contextual e cultural, próprios da prática sócio-histórica, que é a linguagem. Com base numa pesquisa exploratória, descritiva e bibliográfica, o estudo investiga fenômenos de tradição, permanência e mudança presentes nas capas de folhetos de cordel. A partir de um viés simbólico-antropológico (DURAND, 2002) das ciências das significações, a pesquisa dialoga com os pressupostos teóricos das Tradições Discursivas (TD), difundidos por Kabatek (2006, 2012) e Coseriu (1980); além dos estudos culturais e de tradição oral (ZUMTHOR, 1993), folhetos de cordel e da Semiótica Antropológica (RODRIGUES, 2011, 2014a, 2014b, 2017, 2018a, 2018b). Por meio das análises efetuadas, conclui que os folhetos de cordel são instrumentos de representação e manutenção da memória popular nordestina, revelando nas capas retratos da região, sua cultura, memória e imaginário. Para além de sua estrutura (arquitetura e suporte), o cordel abre possibilidades múltiplas de estudo e compreensão de sua atuação/atualização como prática social na cultura nordestina através da leitura e composição verbo-visual/multimodal, o que permite sua continuidade e a manutenção das vozes da cultura que representa.

Published: October 2024

Introduction Avascular necrosis of the femoral head (ANFH) is a phenomenon vascular supply disruption lead to death of bone cells around the femoral head. The disease is a severe health issue all over the world. Within 2 years about 80 % to 85 % of symptomatic cases will result in collapse of the femoral head. Recovery of hip function after total hip arthroplasty (THA) may be influenced by many factors that vary among different racial/ethnic groups. Most findings in this field have been from Western developed nations, and not much information from developing Asian countries is available.

This study aimed to determine the six-month functional outcome and patient–related factors that predict functional recovery in patients with avascular necrosis of the femoral head (ANFH) undertaking total hip arthroplasty (THA).

Methods Between January 2022 and December 2023 there were 143 patients participating in this prospective study. Demographic, medical history and clinical findings were collected from their medical records. The six-month functional outcome was evaluated using the Harris hip score (HHS). The mean age of the participants was 55.90 ± 11.49 years, and the majority (86.7 %) were male. Most patients had excellent (43.4 %) or good outcome (51.7 %).

Discussion Our study had some limitations: the length of the follow-up after surgery is short (6 months), that hospital-related factors like the type and volume of the hospital have not been analyzed. Nonetheless, previous observations suggest that most of the improvement in physical function occurs during the first six months following surgery and remains the same for a long time. However, our sample has typical demographic and clinical characteristics of patients with THA for ANFH, suggesting that determinants of the 6-month functional outcome in the current study could apply to other patients undergoing this surgery.

Results The determinants of excellent outcome were a  higher preoperative HHS (odds ratio (OR): 4.369, 95 % confidence interval (CI) =1.854 – 10.299; p < 0.001) and absence of comorbidity (OR: 2.440, 95 % CI = 1.071 – 5.557, p = 0.034). No demographic (age, gender, body mass index), medical history (using of steroids, alcohol consumption or smoking), or any other clinical parameter (stage or side of the affected hip, time until surgery) had a significant influence on functional outcome.

Conclusion Earlier surgery during functional decline and better management of comorbidity may help improve THA outcomes for patients with avascular necrosis of the femoral head.
Antibacterial effect of semiconductor laser radiation against the strains of S. aureus and P. aeruginosa, leading pathogens in osteomyelitis
Authors: Shipitsyna I. V. , Spirkina E. S.
Published: October 2024

Introduction The study of the antibacterial effect of photodynamic therapy against the leading pathogens of chronic osteomyelitis is one of the promising directions today.

Purpose of the work was to evaluate the antibacterial effect against the strains of Staphylococcus aureus and Pseudomonas aeruginosa with the ALOD-01 laser system in the presence of photodithazine.

Materials and methods The object of the study was 24-hour archival cultures of gram-positive and  gram-negative microorganisms belonging to two taxa: Staphylococcus aureus (25923), Pseudomonas aeruginosa (27853). The  antibacterial effect after the exposure to laser radiation in the presence of photodithazine on the microbial cells of the studied cultures was assessed by the absence of microorganism growth in the area of the light beam.

Results Laser exposure in combination with photodithazine (concentration 0.5–1.0 mg/ml) on S. aureus for two minutes at 200–300 J achieved a bactericidal effect in the beam area. A bactericidal effect on the entire surface of the Petri dish was achieved with light exposure of 400 J for 5 minutes and a photodithazine concentration of 1.0 mg/ml. Laser exposure for 2 minutes in the presence of photodithazine at a concentration of 0.5 mg/ml and 1 mg/ml did not have an antibacterial effect on P. aeruginosa strains. Continuous growth of microorganisms was observed on the dish. Increasing the light dose and exposure time contributed to a decrease in the growth of microbial cells. A bactericidal effect was obtained only in the center of the dish in treating the bacterial suspension with photodithazine at a concentration of 5 mg/ml.

Discussion The effectiveness of PDT depends on the type of microorganisms, the anatomical location of  the  infection site, as well as the properties of the photosensitizer and the laser used. Depending on the structure of the cell wall, different susceptibility of bacteria to photodynamic effects is observed.

Conclusion S. aureus strains can be successfully photoinactivated using photodithazine. For P. aeruginosa strains, it was not possible to find a regime in which microbial cell growth was absent throughout the dish. The  photodynamic reaction occurs only when adequate doses of light energy act on the photosentisizer in the presence of oxygen in the medium, while the photodynamic damage is local and the bactericidal effect is limited by the zone of light exposure.

Introduction Increasing the integration of transcutaneous implants is an important goal for their application in clinical practice.

The purpose of the work was to evaluate the osseointegration of transcutaneous titanium implants with calcium-phosphate coating containing zinc ions.

Materials and methods The studies were performed on 12 male rabbits, who underwent implantation of an original implant into the tibial stump. After implantation, a compression device was installed on the bone, maintaining a load of 3.5 N for 5 weeks. Duration of observation was 26 weeks. The animals were divided into two groups: a control group (n = 6) with an implant without coating and an experimental group (n = 6) with a zinc-substituted calcium-phosphate coated implant.

Results The implant fell out in one case in animals from the control group; no cases of implant loss were noted in the experimental group. It was revealed that the weight concentration of Ca and P in all zones of the bone-implant block of the animals in the experimental group significantly exceeded similar indicators in  the  control group. In the control group, long-term persistence of high levels of C-reactive protein was noted, which was not observed in the experimental group.

Discussion This series of studies has shown that an implant with a zinc-modified calcium-phosphate coating exhibited a more effective integration, in contrast to an uncoated product. The absence of serious adverse reactions to the tested products indicates acceptable tolerability and safety of its use.

Conclusion The implants with a zinc-modified calcium-phosphate coating showed signs of more effective osseointegration compared to the product without additional coating.

Introduction Triphalangeal joint flexion contracture of the fingers is a common and challeging posttraumatic hand condition. The goal of surgical treatment is to correct finger deformity and increase interphalangeal range of motion.

The objective was to systematize data on the causes of post-traumatic triphalangeal joint flexion contracture of the fingers and methods of surgical correction.

Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www.elibrary.ru), the National Library of Medicine (www.pubmed.org), ScienceDirect, Google Scholar, Ovid databases according to PRISMA recommendations. Literature searches included both Russian and English studies, with one or more cases of post-traumatic triphalangeal joint flexion contracture of the fingers with the deformity surgically corrected. Cases of non-traumatic flexion contractures were excluded. Etiological factors of flexion contractures, heterogeneity of definitions and methods for recording the range of motion in the joint, anatomical features, surgical correction of flexion contractures and postoperative complications were reviewed.

Results Common causes of flexion contractures included burns (32.3 %), dislocations and fracturedislocations of the finger joints (23.5 %). The median postoperative follow-up period was 13.5 months after surgical treatment. Surgical correction was produced with external fixation device (EFD) in 40 % of cases, open procedures performed in 50 % and a combined technique employed in one case (10 %). Based on calculations of the odds ratios of postoperative complications, a weak positive linear relationship was revealed between EFD and pain syndrome, and a weak negative linear relationship was observed between the open procedure and pain.

Discussion There is heterogeneity of approaches regarding methods for correcting flexion contractures, surgical approaches, techniques for mobilizing joints and releasing the anatomical structures of the finger with  open procedures, the distraction rate with EFD, methods for repair of soft tissue defects following the treatment of flexion contractures of interphalangeal joint of a finger.

Conclusion Open procedures are commonly used for precise elimination of all components of flexion contracture of the joint and repair of soft tissue defects of the finger. A weak positive linear relationship was revealed between EF and pain syndrome. There was no significant correlation between open techniques and complications. There were no correlations between the treatment method and the contracture type; there are no treatment regimens for patients with this pathology.

Introduction The advancement of surgery is set against a backdrop of continuous development and surgical innovations have transformed the way clinical care is delivered. Revision surgery might be required to  address complications of primary arthroplasty. The first stage of revision arthroplasty would involve removal of  an  implant and placement of an antibiotic-impregnated cement spacer to maintain the joint space and stability, prevent soft tissue retraction, provide local antibiotic release and preserve bone tissue for revision implantation at the final stage of revision. Custom-made articulating spacers are a promising tool for optimizing the first stage of revision arthroplasty.

The objective was to summarize the current data and present comprehensive information about spacers used in two-stage revision arthroplasty including manufacturing techniques, physical and chemical properties, clinical applications, the possibility of customization within the first stage of revision arthroplasty, current and promising directions for research.

Material and methods The original literature search was conducted on key resources including Scientific Electronic Library (www.elibrary.ru), the National Library of Medicine (www.pubmed.org), the Cochraine Library (www.cochranelibrary.com) between 2018 and 2023 using search words and phrases: total arthroplasty, complications, revision arthroplasty, articulating spacer, periprosthetic joint infection, additive manufacturing, 3D printing.

Results A comparative analysis of factory supplied, home-made, dynamic and static spacer models showed that the choice of articulating spacers for revision arthroplasty of major joints is of great relevance. Advantages of factory-made spacers include standardized range of sizes, the reliability and availability for medical institutions. They are characterized by limited use in repair of severe bone defects.

Discussion Custom-made articulating spacers enable specific tailoring to accommodate individual defects. Despite high expectations from custom-made spacers, development of optimal technologies for rapid prototyping is essential. Investments in research and development in this area have the potential to create innovative solutions that can significantly improve the results of revision arthroplasty.

Conclusion The paper explores the importance of systemization of knowledge about spacers and the role of new research in improving the design and functionality. Progress in the field of materials science, additive technologies and a personalized approach to spacer manufacturing can expand possibilities of  revision arthroplasty and the effectiveness. Personalized approaches and improved methods of local drug delivery that provide controlled release of antibiotics can improve the results of treatment of periprosthetic joint infections.

The article presents the results of optimization of the work process of a single-stage axial turbine in order to increase its efficiency. During optimization, it was necessary to preserve the construction of the original turbine as much as possible. To solve this problem, a parameterization scheme for turbine blades and path contours was developed, taking into account the design and technological limitations. The turbine nozzle blade had an inside baffle. To control the possibility of placing the baffle, a special program was developed that automatically monitors the spatial position of the sections of the blade of the nozzle set. A post-processing program was developed to control the flow parameters at the turbine outlet in height. The efficiency and the vertical deviation of the angle of the outflow from the turbine from the original one were used as optimization criteria. The limitations were the mass flow rate of the working fluid and the total pressure ratio of the turbine. The problem was solved in several stages with different changing variables. As a result of solving the problem, it was possible to increase the turbine efficiency by 0.9%

Currently, small spacecraft with both optoelectronic and radar imaging equipment are becoming increasingly common. The purpose of the work is to improve the efficiency of preliminary assessment of achievable characteristics of radio surveillance payloads at the initial stages of design of small spacecraft. The paper describes the advantages of using radar imaging equipment, as well as the main trends in its development. The main areas of application of spacecraft with radar of different frequency ranges are given; the advantages of each frequency range are described. The methodology of determining the parameters of the trajectory signal when the platform moves in a circular orbit, taking into account the assumptions associated with estimating the size of the irradiation zone in azimuth is considered. Based on the considered methodology, a program is developed in Python programming language that makes it possible to estimate the length of synthesized aperture, synthesis time and azimuthal resolution of the target equipment on the basis of mass and dimensional characteristics of the antenna and spacecraft orbit parameters. A graphical user interface has been developed for the program which allows the user to interactively vary the initial data for calculation and evaluate the graphical representation of the result. The developed software system can be used for calculation of the main design parameters of small spacecraft with radar imaging equipment at the preliminary design stage.

The method assumes implementation of weight and aerodynamic balance in the main flight modes, it can consider aircraft-type unmanned aerial vehicles with one or two lifting surfaces, applies parallel calculations, and automatically generates a three-dimensional geometric model of the aircraft appearance based on the optimization results. A method for accelerating by more than three times the process of solving the problem of optimizing aircraft takeoff weight parameters by introducing the target function into the set of design variables is proposed and demonstrated. The results of assessing the reliability of the mathematical models used for aerodynamics and the correct calculation of the target function are presented, taking into account various constraints. A comprehensive check of the operability and effectiveness of the method were considered by solving demonstration problems by optimizing more than ten main design parameters of the appearance of two existing heavy-class unmanned aerial vehicles with known characteristics from open sources.
