AbstractObjectivesTo evaluate the surgical techniques, approaches, audiological outcomes and complications of endoscopic stapes surgery.MethodsSystematic searches of the literature were performed in PubMed, Web of Science and Scopus databases, to identify studies of patients who underwent stapes surgery using endoscopic approaches and studies reporting objective post-operative hearing outcomes. The following information was extracted: surgery duration, complications, surgical technique and audiometric results.ResultsFourteen studies were selected for appraisal, which included a total of 282 ears subjected to endoscopic stapes surgery. Endoscopic stapes surgery seems to provide adequate visualisation of the middle-ear structures, thereby allowing less invasive surgery and potentially equivalent audiological outcomes as compared with a traditional microscopic approach. Other advantages of endoscopic stapes surgery include decreased surgery time, a reduced need for drilling, and auditory results comparable to those of microscopic techniques.ConclusionStudies have shown that endoscopic stapes surgery has similar surgical and functional advantages as compared with microscopic surgery.

Despite recent improvements in surgical technique, the morbidity of distal pancreatectomy remains high, with pancreatic fistula being the most significant postoperative complication. A systematic review of randomized controlled trials (RCTs) dealing with surgical techniques in distal pancreatectomy was carried out to summarize up-to-date knowledge on this topic. The Cochrane Central Registry of Controlled Trials, Embase, Web of Science, and Pubmed were searched for relevant articles published from 1990 to December 2013. Ten RCTs were identified and included in the systematic review, with a total of 1286 patients being randomized (samples ranging from 41 to 450). The reviewers were in agreement for application of the eligibility criteria for study selection. It was not possible to carry out meta-analysis of these studies because of the heterogeneity of surgical techniques and approaches, such as varying methods of pancreas transection, reinforcement of the stump with seromuscular patch or pancreaticoenteric anastomosis, sealing with fibrin sealants and pancreatic stent placement. Management of the pancreatic remnant after distal pancreatectomy is still a matter of debate. The results of this systematic review are possibly biased by methodological problems in some of the included studies. New well designed and carefully conducted RCTs must be performed to establish the optimal strategy for pancreatic remnant management after distal pancreatectomy.

Background: Pectoralis major muscle (PMM) tendon ruptures are becoming more common. Multiple techniques for fixation of the avulsed tendon to its humeral insertion have been described. None of these techniques has been reviewed to compare outcomes in efforts to establish a first-line surgical technique. Purpose: To systematically review and analyze the data available in the literature to establish a clinically superior surgical technique and time frame in which surgery should occur. Study Design: Systematic review; Level of evidence, 4. Methods: A systematic literature review was conducted. Only studies reporting the surgical techniques and outcomes of PMM repair were included. Data including patient age, injury mechanism, type and extent of the rupture, time from injury to surgery, surgical technique, outcome including complications, steroid use, location and year of publication, and activity level were extracted from the included studies. Statistical and descriptive analyses were conducted on the available literature. Results: Of 259 cases from studies that provided the timing of repair, 72.6% (n = 188) were repaired acutely, while the remaining were repaired more than 8 weeks after the injury. There was no statistical difference found in the outcomes of these repairs. There were 265 cases included in the statistical analysis comparing the outcomes of surgical techniques. The odds of an excellent/good outcome were significantly better for the transosseous suture (TOS) compared with the unicortical button (UCB) technique (odds ratio [OR], 6.28 [95% CI, 1.37-28.75]; P = .018) and also for the suture anchor (SA) compared with the UCB technique (OR, 3.40 [95% CI, 1.06-10.85]; P = .039). The odds of an excellent/good outcome were not significantly different when comparing the TOS, SA, and TOS with trough techniques to one another. The probability of complications was highest with the TOS with trough technique (12.0%), although the odds of having a complication were not statistically significant for any single technique compared with the others. Conclusion: The low quality of evidence available limited this review. There were no significant differences observed in the outcomes of PMM repair based on the timing of repair. The TOS and SA techniques had statistically significantly greater odds of resulting in an excellent/good outcome compared with the UCB technique, but 1 study that contributed to this analysis may have statistically skewed the results for the UCB technique. Therefore, all 3 surgical techniques are accepted options, and the best technique is that with which the surgeon is most proficient and comfortable. Comparative research with a greater level of evidence is needed to determine a definitive first-line surgical technique.

Peripheral Neurectomy

Background: Management of upper limb spasticity remains challenging. Selective peripheral neurectomy (SPN) is a relatively recent intervention for cases refractory to medical therapy. The aim of this study was to conduct a systematic review looking at the efficacy and outcomes of SPN, in order to clarify the patient selection criteria and surgical technique. Methods: A search of MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, Web of Science Core Collection, Open Grey and CINAHL was conducted. Inclusion criteria included studies comparing pre- and post-operative outcomes for SPN, neurectomy, fasciculotomy and upper limb spasticity. Results: Only case series were reported with no randomised controlled trials found. 7 studies met the inclusion criteria with a total of 174 patients. A meta-analysis was not possible due to the degree of baseline heterogeneity. All studies had no control arm for comparison of outcomes, with a high risk of bias due to poor internal and external validity, as well as design and performance bias. Surgical techniques differ vastly between studies, with percentage of fascicles ablated between 30–80% and length of neurectomy between 5–10 mm. Some advocated removing end branches while others performed fascicular SPN proximally. 13 patients underwent orthopaedic or neurosurgical procedures, which are both confounding factors. All studies reported an improvement in spasticity although functional outcomes were reported with non-standardized measures. Recurrence rates were reported to be 0–16.1% (mean 3.72%). Conclusions: From this systematic review, SPN appeared to be a useful technique in selected cases, but overall no firm conclusions can be drawn regarding the best surgical technique, or the extent of functional improvement.

Objective: During the postoperative period, most patients with otosclerosis report vertigo and/or nausea caused by interventions within the inner ear. The aim of this study was to evaluate both early and late vertigo associated with hearing improvement after stapes surgery for otosclerosis. Methods: The analysis included 170 patients admitted to the hospital undergoing their first surgery for otosclerosis. Audiological diagnostics, surgical techniques, and symptoms reported by the patients were all analyzed. Results: A statistical correlation and an unfavorable influence of late, undesired symptoms, such as vertigo, nausea/vomiting, and nystagmus, on final hearing improvement after surgical treatment of otosclerosis were found. Prostheses that were too long or placed too deep within the inner ear space were the most frequent cause of both vertigo and lack of hearing improvement observed after stapedotomy. Conclusions: A significant negative influence on bone conduction thresholds, particularly at 2000 Hz, was associated with vestibular symptoms persisting for 7 days after the surgery. Symptoms of impaired bony labyrinth function after stapedotomy, persisting for more than 1 year, were associated with insufficient reduction of the air–bone gap and worse improvement in bone conduction thresholds at 1000 and 2000 Hz. The cause of both problems was related to a prosthesis that was too long or placed too deep in the inner ear during stapedotomy.

Abstract Background Osteomyelitis variolosa is a self-limiting disease triggered by variola virus that cannot be prevented or repaired. Smallpox has been eradicated for 40 years, and complications that remain after smallpox has been cured have become a remarkable diagnostic challenge for contemporary physicians. In this systematic review, we searched PubMed (MEDLINE), Web of Science, and Google Scholar for cases on complications, diagnosis, and treatment for osteomyelitis variolosa between January 1980 and February 2021. Results Ten papers and eleven finished cases, all patients from India, were included for comparison with the present case. In total, 100% of patients presented with bilateral elbow deformities, the ankle was the second most common site of lesion in 50%, and knee lesions accounted for 25% in this study. Flexion contracture, joint instability, secondary arthritis, and fracture are common complications of osteomyelitis variolosa, and most patients receive conservative treatment, while internal fixation has good results for combined fractures. Conclusions Although osteomyelitis variolosa is not a direct threat to the safety of patients, severe skeletal deformities can have a significant impact on quality of life. With advances in surgical techniques, clinicians are offering an increasing number of treatment options for patients with osteomyelitis variolosa. However, most importantly, smallpox has basically been removed from the historical arena, and for areas where smallpox was once endemic, physicians need to deepen the understanding of this disease again.

Background: Prediction of proteins’ secondary structure is one of the major steps in the generation of homology models. These models provide structural information which is used to design suitable ligands for potential medicinal targets. However, selecting a proper tool between multiple Secondary Structure Prediction (SSP) options is challenging. The current study is an insight into currently favored methods and tools, within various contexts. Objective: A systematic review was performed for a comprehensive access to recent (2013-2016) studies which used or recommended protein SSP tools. Methods: Three databases, Web of Science, PubMed and Scopus were systematically searched and 99 out of the 209 studies were finally found eligible to extract data. Results: Four categories of applications for 59 retrieved SSP tools were: (I) prediction of structural features of a given sequence, (II) evaluation of a method, (III) providing input for a new SSP method and (IV) integrating an SSP tool as a component for a program. PSIPRED was found to be the most popular tool in all four categories. JPred and tools utilizing PHD (Profile network from HeiDelberg) method occupied second and third places of popularity in categories I and II. JPred was only found in the two first categories, while PHD was present in three fields. Conclusion: This study provides a comprehensive insight into the recent usage of SSP tools which could be helpful for selecting a proper tool.

The objective of this paper is to present a review of current research on the valuation of ecosystem services, using emergy evaluation methodology (EME). A bibliometric analysis and a systematic review were carried out between 2000 and 2020, using all of Web of Science database subfields that collected 187 papers, selected through the keywords “emergy” and “ecosystem services”. In the second part of the research, we carried out a new search on Web of Science of the 187 initial articles produced, with the words “valuation” and “economic”, in order to analyze those directly related to the evaluation of ecosystem services. The results showed that the EME method is an effective tool to evaluate ecosystem services, since it relates economic and ecological aspects in the evaluations. The research also indicated that the use of isolated methods does not appear to be the most appropriate solution, and that emergy used in combination with other methodologies can be used to obtain more accurate and comprehensive results to evaluate natural resources.

Introduction: The objective of this systematic review is to assess the effect of vibrational force on biomarkers for orthodontic tooth movement. Methods: An electronic search was conducted for relevant studies (up to December 31, 2020) on the following databases: Pubmed, Google scholar, Web of Science, Cochrane Library, Wiley Library, and ProQuest Dissertation Abstracts and Thesis database. Hand searching of selected orthodontic journals was also undertaken. The selected studies were assessed for the risk of bias in Cochrane collaboration risk of bias tool. The “traffic plot” and “weighted plot” risk of bias distribution are designed in the RoB 2 tool. The 2 authors extracted the data and analyzed it. Results: Six studies fulfilled the inclusion criteria. The risks of biases were high for 4, low and some concern for other 2 studies. The biomarkers, medium, device, frequency and duration of device, as well as other data were extracted. The outcomes of the studies were found to be heterogenous. Conclusion: One study showed highly statistically significant levels of IL-1 beta with <.001. Rate of tooth movement was correlated with levels of released biomarkers under the influence of vibrational force in 3 studies, but it was found to be significant only in 1 study. It was further observed that vibration does not have any significant reduction in pain and discomfort.

Educational technology has become an increasingly important element for improving the teaching and learning process of students. To achieve these goals, it is essential that teachers have the skills they need to be able to introduce technology into their teaching practice. However, this is often overwhelming and stressful for many of them. The aim of this review was to find out how research on teacher stress and anxiety associated with the use of educational technology was proceeding. A systematic review was conducted using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines through the following bibliographic databases: PubMed, Web of Science, and Scopus. Sixteen articles were found from the review. The main findings show that teachers present high levels of anxiety or stress due to their use of educational technology in the classroom. Among the conclusions, the need for research on different strategies to prevent the emergence of these anxiety and stress symptoms in teachers stands out.
