Abstract Wasted time in the operating room results in higher operating costs and greater post-operative complications. One effective way to reduce operation time is automating basic processes that occur during surgery. Given the rise of smart-home devices, implementation of virtual assistants became a feasible solution in many medical settings. With a consumer smart-home device and off-the-shelf components, we engineered a voice-controlled smart surgical bed that adjusts the bed configuration via a voice input. The resulting device is expected to optimize human resources and reduce surgical site infection by eliminating the need of a traditional touch control mechanism. Future work is needed to develop its proprietary hardware and software, and continuous collaboration with medical personnel to bring this device into market.

Introduction: The aim of this study was to compare laparoscopic and open partial nephrectomy (PN) for renal tumors of high surgical complexity (PADUA score ⩾10). Methods: We retrospectively evaluated 93 consecutive patients who underwent PN at our department from January 2015 to September 2019. 21 patients underwent open partial nephrectomy (OPN) (Group A) and 72 underwent laparoscopic partial nephrectomy (LPN) (Group B). All OPNs were performed with a retroperitoneal approach, while all LPNs were performed with a transperitoneal approach by a single surgical team. Post-operative complications were classified according to the Clavien-Dindo system. Results: The two groups showed no difference in terms of patients’ demographics as well as tumor characteristics in all variables. Group A was found to be similar to group B in terms of operation time ( p = 0.781), conversion to radical nephrectomy ( p = 0.3485), and positive surgical margins ( p = 0.338) while estimated blood loss ( p = 0.0205), intra-operative ( p = 0.0104), and post-operative ( p = 0.0081) transfusion rates, drainage time ( p = 0.0012), pain score at post-operative day 1 (<0.0001) were significantly lower in Group B. The rate of enucleation and enucleoresection/polar resection was similar ( p = 0.1821) among the groups. Logistic regression analysis indicated that preoperative factors were not independently associated with the surgical approach. There was a statistically significant difference in complication rate (<0.0001) between the two groups even if no significant difference in terms of grade ⩾3 post-operative complications ( p = 0.3382) was detected. Discussion: LPN represents a feasible and safe approach for high complex renal tumors if performed in highly experienced laparoscopic centers. This procedure offers good intraoperative outcomes and a low rate of post-operative complications.

Play presents a popular pastime for all humans, though not all humans play alike. Subsequently, Human–Computer Interaction Games research is increasingly concerned with the development of games that serve neurodivergent 1 players. In a critical review of 66 publications informed by Disability Studies and Self-Determination Theory, we analyse which populations , research methods, kinds of play and overall purpose goals existing games address. We find that games are largely developed for children, in a top-down approach. They tend to focus on educational and medical settings and are driven by factors extrinsic to neurodivergent interests. Existing work predominantly follows a medical model of disability, which fails to support self-determination of neurodivergent players and marginalises their opportunities for immersion. Our contribution comprises a large-scale investigation into a budding area of research gaining traction with the intent to capture a status quo and identify opportunities for future work attending to differences without articulating them as deficit.

Objective: To compare early versus delayed laparoscopic cholecystectomy in acute calculous cholecystitis in terms of mean operative time, hospital stay, conversion rate to open surgery and post-operative complications. Study Design: Quasi experimental study. Place and Duration of Study: Army Liver Transplant Unit, Department of Surgery, Pak-Emirates Military Hospital Rawalpindi, from Jul to Dec 2018. Methodology: A total of 170 patients (85 in each group) diagnosed as a case of acute calculous cholecystitis who met the sample selection criteria were included. Group A patients underwent early laparoscopic cholecystectomy within 72 hours of admission while group B patients underwent conservative management followed by delayed laparoscopic cholecystectomy after 6 weeks. All patients were followed for operative time, hospital stay, per-operative difficulties encountered and post-operative complications. Results: Group A had a mean operation time of 43.9 ± 11.1 minutes, while group B had a mean operation time of 45.8 ± 10.1 minutes (p=0.83). The mean duration of hospitalization was 2.8 ± 1.1 days in group A and 5.3 ± 0.8 days in group B (p<0.001). Complications were measured at a frequency of 14.1% in group A and 5.9% in group B (p=0.07). Conclusion: Early laparoscopic cholecystectomy is better than delayed laparoscopic cholecystectomy in acute calculous cholecystitis in terms of hospital stay and per-operative difficulties faced. The post-operative complications between the two groups are comparable.

Abstract Laryngeal papillomatosis is a benign disease in the larynx but with the potential to develop into significant complications as a result of its high recurrence rate. CO2 laser and radiofrequency controlled ablation (coblation) have been used to treat recurrent respiratory papillomatosis, but detailed comparisons of their respective treatment outcomes are not fully investigated. This retrospective study examines the procedure time, time interval between interventions, blood loss during operation, post-operative complications and pain scores among patients who received either CO2 laser or radiofrequency coblation interventions for laryngotracheal recurrent respiratory papillomatosis. Compared with CO2 laser intervention, radiofrequency coblation significantly reduced operation time, time interval between interventions, blood loss during operation and number of times bipolar electrocoagulation needed in each procedure. Post-operatively, pain scores after radiofrequency coblation were significantly lower than those after CO2 laser intervention. Incidence rates of post-operative complications, in terms of palate pharyngeal mucosa damage, bleeding and subcutaneous emphysema, were also significantly reduced after radiofrequency coblation. Low-temperature radiofrequency coblation is a superior intervention compared with CO2 laser against laryngotracheal recurrent respiratory papillomatosis.

Cervical epidural injection (CEI), which is widely used for the treatment of cervical radiculopathy, sometimes has been associated with post-operative complications. Recently, EPI-DetectionTM, which detects the negative pressure of the epidural space and notifies the proceduralist by flashing a light and producing a beeping sound, was introduced. We assumed that the newly developed device could be as safe and efficient as the conventional loss of resistance (LOR) method. Therefore, we aimed to evaluate the effectiveness of the EPI-DetectionTM and compare it to that of the conventional LOR method. We randomly assigned 57 patients to the LOR and EPI-Detection groups (29 and 28 patients, respectively). Subjects were treated with interlaminar CEI (ILCEI) using one of two methods. The measured parameters, i.e., operation time and radiation dose were lower in the EPI-DetectionTM group (4.6 ± 1.2 min vs. 6.9 ± 2.1 min; and 223.2 ± 206.7 mGy·cm2 vs. 380.3 ± 340.9 mGy·cm2, respectively; all p < 0.05) than in the LOR group. There were no complications noted in either group. Both the EPI-DetectionTM and LOR methods were safe and effective in detecting the epidural space, but the former was superior to the latter in terms of operation time and radiation exposure. The EPI-DetectionTM may help perform ILCEI safely.

Based on analysis of the cargo selecting strategy of fixed shelf automated warehouse, the idea of path optimization is put forward and the stacker path optimization method is studied. A mathematical model of stacker operation path optimization is built to minimize the length of operation path and the operation time. The model is solved by using the ant colony optimization method. Simulation shows that chosen stacker operation path by using the optimization model and optimization algorithm, can not only reduce energy consumption and warehouse operating costs, but also improve the efficiency of goods storage.

AbstractProblem:The advantages of bilateral, simultaneous cochlear implantation include: the possibility to pre-empt cochlear calcification following meningitis; reduction of the intervention to only one procedure, general anaesthetic and course of clinical care (with obvious benefits for the patient); and greater cost-effectiveness. The disadvantages of such a procedure include: doubling the risk of associated complications; placing the patient on the implanted side during contralateral implantation; the possibility of vestibular alteration simultaneously in both ears; the need for precise planning of symmetrical incisions and implant sites; and longer surgery time.Methods:The study cohort included 10 children who underwent bilateral, simultaneous cochlear implantation using the suprameatal approach.Results:The overall operation time, inclusive of anaesthesia, was approximately three hours in all cases. None of the children had any intra- or post-operative complications.Conclusions:From a surgical perspective, bilateral, simultaneous cochlear implantation is a safe procedure. The use of a non-mastoidectomy approach is recommended.

Blockchain technology is increasingly used worldwide to enhance the performance and profit of any environment through its defining characteristics, such as security, auditability, immutability, and inconspicuousness. Owing to these characteristics, the blockchain can be used in various non-financial operations of some domains, such as the Internet of Things (IoT) and distributed computing. However, implementing blockchain technology in IoT is not always a feasible solution because blockchain deployment is costly, it has limited extensibility and provides irregular bandwidth and latency. In this regard, a simple size extensible (SSE) blockchain has been proposed to provide an optimal solution for IoT environments by satisfying the needs of the IoT environment as well as ensuring end-to-end security. The implementation of the proposed blockchain develops an overlay network to obtain a distributed environment where the blockchain is handled by the resources present therein. Two novel algorithms were introduced into the proposed system to minimize the irregularity and latency on one hand, and to maximize the throughput of the system on the other. The shared-time depending agreement algorithm (STD) minimizes the irregularity in the extraction operation and latency. The other, the shared throughput administration algorithm (STA) justifies the overall collection of the transmission load in the network and maintains the performance of the blockchain. The proposed system was applied to smart home IoT appliances to test the performance of the proposed system. The experimental results show that the proposed blockchain system minimizes nearly 70% of the data irregularity, latency, and furthermore, 30% of the blockchain extensibility is maximized as compared to the existing systems.

Introduction. Percutaneous nephrolithotomy (PNL) is the method of choice for the treatment of patients with kidney stones larger than 2 cm. Mini-percutaneous nephrolithotomy (mini-PNL) became widespread due to reduction of injury associated with surgical approach. Creation of puncture access to the pelvicalyceal system without ureteral catheterization is also recently described. The main benefits of such technique are reduction of total operative time and the radiation exposure to the patient and medical personnel. The results of using mini-PNL without prior ureteral catheterization remain insufficiently studied, which predetermined the goal of our study. Purpose. Compare the efficacy and duration of mini-PCNL with and without ureteral catheterization. Materials and methods. We analyzed the treatment outcomes of 111 patients with a single kidney stone. Group I included 60 patients who underwent mini-PCNL according to the standard technique. Group II included 51 patients who underwent mini-PCNL without prior catheterization of the ureter. The average stone size was 19.2 0.92 mm and 18.6  0.93 mm in groups I and II, respectively. The puncture of the pyelocaliceal system of the kidney was performed under X-ray control and US guidance using the free-hand technique. Results. In group I, complete elimination of the stone was achieved in 55 (92%) patients and the mean duration of the operation was 108,3 34,85 min (range: 60 to 210). In group II, complete elimination of the stone was achieved in 50 (90%) patients and the mean duration of the operation was 69,7 22 min (range: 25 to 120 min). In all cases, the severity of complications did not exceed grade II according to Clavien classification, and their rate was 6,7% and 5,9% in group I and group II, respectively. Conclusions. According to the results of the study, the compared groups did not differ in their post-operative complication and stone-free rates. Avoidance of routine ureteral catheterization significantly reduces the operation time and hence the anesthetic risk and radiation load.
