Study of the dosing tissue distraction clinical efficacy in the soft tissue defects treatment of various etiologies in the lower extremities

Justification. The most methods of extensive skin and soft tissue defects are aimed at accelerating wound healing  and preventing infectious complications. To improve the effectiveness of such defects treatment, a method of dosed tissue distraction (MDTD) is used, consisting in the application of a continuously acting load to the area of healthy soft tissue in close proximity to the wound defect.Purpose. It performed the evaluation of the medico-social  effectiveness of the introduction into clinical practice of developed methods and devices for implementing MDTD in  the treatment of skin and soft tissue defects of the extremities.Methods. 407 patients were treated with wound defects of  the extremities, which were divided into two groups: the main group – 198 patients in whose treatment MDTD was applied using original methods and devices; comparison group – 209 patients, in whose treatment standard treatment methods were applied. Comparison of the long-term results of treatment according to the frequency of repeated operations, complications, indicators of quality of life, frequency of disability.Results. The use of MDTD is characterized by better performance compared with the use of standard approaches. There is a decrease in the frequency of performing reconstructive plastic surgery after inpatient treatment (9–10 times), remote complications by 2.6 times, a reduced value of the Vancouver scale (by 28.8%), quality of life indicators higher levels. The use of the proposed approach is characterized by a shorter duration of treatment (by 26.0%), duration of disability (1.4 times), cases of disability (2.2 times).Conclusion. The use of MDTD is characterized by high medical and social efficiency, allows to reduce the cost of treating extensive skin and soft tissue defects by reducing the length of hospitalization, the frequency of repeated rehabilitation and reconstructive operations, accelerated recovery of patients, improving the quality of life and reducing the incidence of disability

Vacuum Therapy in Complex Treatment of Purulent-Necrotic Diseases of Soft Tissues: Clinical Cases

Background. Radical surgeries for phlegmons, abscesses, necrotizing infection are often followed by extensive wounds which require an individual approach to their rapid closure by means of plastic surgery methods. In such a case, the optimal wound therapy is primary healing with the use of vacuum therapy.Cases description. The study involved three clinical trials of patients with acute purulent-necrotic diseases of soft tissues of various localizations, volumes and grades, for which vacuum therapy was used as a part of complex therapy. Surgical interventions are proved to be urgently performed in acute purulent-necrotic diseases. Early reconstructive skin and bone plastic surgery aimed at closing post-operative wound defects is also very important.Conclusion. In the demonstrated clinical cases, the purulent process was stopped and wound therapy was performed by means of primary healing, which undoubtedly ensures medical and social rehabilitation of such patients. Notably, vacuum drainage is not an independent method, but an important component in the complex active surgical treatment of purulent wounds

Experts' Judgments of Management Journal Quality:An Identity Concerns Model

Many lists that purport to gauge the quality of journals in management and organization studies (MOS) are based on the judgments of experts in the field. This article develops an identity concerns model (ICM) that suggests that such judgments are likely to be shaped by the personal and social identities of evaluators. The model was tested in a study in which 168 editorial board members rated 44 MOS journals. In line with the ICM, respondents rated journal quality more highly to the extent that a given journal reflected their personal concerns (associated with having published more articles in that journal) and the concerns of a relevant ingroup (associated with membership of the journal’s editorial board or a particular disciplinary or geographical background). However, judges’ ratings of journals in which they had published were more favorable when those journals had a low-quality reputation, and their ratings of journals that reflected their geographical and disciplinary affiliations were more favorable when those journals had a high-quality reputation. The findings are thus consistent with the view that identity concerns come to the fore in journal ratings when there is either a need to protect against personal identity threat or a meaningful opportunity to promote social identity

Effect of cyclosporin A on proteinuria in the course of glomerulopathy associated with WT1 mutations

Denys–Drash syndrome (DDS) is characterized by progressive glomerulopathy caused by diffuse mesangial sclerosis (DMS), genitourinary defects, and a higher risk of developing Wilms’ tumor. It is commonly assumed that the DMS is unresponsive to any medications. In this report, we present a patient with Denys–Drash syndrome, in whom the cyclosporine A (CsA) was found to induce total remission. This observation and observations of other authors confirm that in genetic forms of nephrotic syndrome, the proteinuric effect of CsA may be due to a non-immunologic mechanism. We confirm the beneficial effect of CsA treatment in DDS; however, the potential nephrotoxicity of this drug will probably not allow long-term use

Impact Factor: outdated artefact or stepping-stone to journal certification?

A review of Garfield's journal impact factor and its specific implementation as the Thomson Reuters Impact Factor reveals several weaknesses in this commonly-used indicator of journal standing. Key limitations include the mismatch between citing and cited documents, the deceptive display of three decimals that belies the real precision, and the absence of confidence intervals. These are minor issues that are easily amended and should be corrected, but more substantive improvements are needed. There are indications that the scientific community seeks and needs better certification of journal procedures to improve the quality of published science. Comprehensive certification of editorial and review procedures could help ensure adequate procedures to detect duplicate and fraudulent submissions.Comment: 25 pages, 12 figures, 6 table

Хирургическое лечение высоких несформированных тощекишечных свищей методом отключения из заднебокового доступа

Objective. The aim of the study was to develop the safest technique for surgical disconnection of high, unformed jejunal fistulas, so as to avoid problems with detection the intestine leading to the fistula and to avoid complications of viscerolysis.Material and methods. The authors present their experience in surgical management of 35 patients with high delimited unformed debilitating jejunal fistulas. Of these, 22 patients were included in the comparison group; their fistulas were closed or disconnected with the known methods. Findings obtained from other 172 patients with adhesive intestinal obstruction after infectious complications of laparotomic wounds and topography of visceroparietal planar adhesions of the peritoneum were analyzed. After studying the nature and location of visceroparietal adhesions, the authors could develop a technique for proximal disconnection of high delimited unformed debilitating jejunal fistulas using posterolateral access which was applied in 13 patients from the studied group.Research results. The proposed technique of unilateral disconnection of high unformed jejunal fistulas reduces duration, damage and risk of prolonged bowel deserosing. As a result, a significant decrease in postoperative mortality from 59.1 ± 9.2% to 23.1 ± 11.2% (t=2.5; p<0.05) was registered. Due to the preoperative endoscopic marking showing direction to the fistula of intestinal loop and duodenojejunal junction, intraoperative orientation was more accurate and took much less time than in the comparison group. The posterolateral surgical approach to the fistula in the jejunal loop reduced the risk of its damage, since there was no need for extensive enterolysis anymore. Therefore, postoperative period in patients of the studied group was better and with fewer complications than in the comparison group.Conclusion. The posterolateral access prevented extended viscerolysis and allowed to put a reliable and atraumatic interintestinal anastomosis so as to disconnect the fistula. The unilateral disconnection of the jejunal fistula at postoperative intestinal paresis unloaded the interintestinal anastomosis, similar to Meidl’s definitive jejunostomy. The abovementioned positive aspects of the proposed surgical intervention allowed to significantly decrease postoperative complications and mortality rate, if to compare with outcomes after known surgical interventions with a similar purpose.Цель исследования – разработка наиболее безопасного способа хирургического отключения высоких несформированных тощекишечных свищей, лишенного трудностей обнаружения, приводящей к свищу кишки, и осложнений висцеролиза.Материал и методы исследования. Представлен опыт хирургического лечения 35 больных высокими отграниченными несформированными истощающими тощекишечными свищами. Из них 22 пациентам, вошедшим в группу сравнения, свищи закрывали или отключали известными способами. На материале хирургического лечения других 172 больных спаечной кишечной непроходимостью, перенесших инфекционные осложнения со стороны лапаротомных ран, изучена топография висцеро-париетальных плоскостных спаек брюшины. Результаты изучения природы и расположения висцеро-париетальных спаек позволили разработать способ проксимального отключения высоких отграниченных несформированных истощающих тощекишечных свищей из заднебокового доступа, который был применен у 13 больных, вошедших в основную группу наблюдения.Результаты. Предложенный способ одностороннего отключения высоких несформированных тощекишечных свищей уменьшил продолжительность, травматичность вмешательства и риск протяженного десерозирования кишечника. Результатом явилось достоверное снижение послеоперационной летальности с 59,1 ± 9,2 до 23,1 ± 11,2 % (t = 2,5; p < 0,05). Благодаря предоперационной эндоскопической маркировке, приводящей к свищу кишечной петли и дуодено-еюнального перехода, интраоперационная ориентировка выполнялась точнее и занимала гораздо меньше времени, чем в группе сравнения. Заднебоковой хирургический доступ к приводящей к свищу тощекишечной петле снизил риск ее повреждения, так как отпала необходимость протяженного энтеролиза. Поэтому у больных основной группы наблюдения послеоперационный период протекал легче и с меньшим количеством осложнений, чем в группе сравнения.Заключение. Заднебоковой доступ предотвратил необходимость протяженного висцеролиза и позволил надежно и атравматично выполнить межкишечный анастомоз, отключающий свищ. Одностороннее отключение тощекишечного свища в периоде послеоперационного пареза кишечника обеспечило разгрузку межкишечного анастомоза, подобно дефинитивной еюностоме Майдля. Приведенные положительные стороны предложенного оперативного вмешательства обусловили достоверное снижение послеоперационных осложнений и летальности по сравнению с результатами известных хирургических операций того же назначения
