Staples versus sutures for skin closure in hip arthroplasty: a meta-analysis and systematic review

Objective The purpose of the present study was to estimate complications and other outcomes associated with staple and suture closure after hip arthroplasty through meta-analysis techniques and a systematic review. Methods We searched for articles in EMBASE, PubMed, Medline, Web of Science and the Cochrane Library. To determine the eligibility of the searched trials, Cochrane Collaboration's Review Manager software was used to perform the meta-analysis. Results Five randomized controlled trials and one retrospective cohort trial were included in our study. Our study indicated that for skin closure after hip arthroplasty, the risks of superficial infection and prolonged discharge were higher with staples than with sutures. There was no significant difference between the two groups in terms of allergic reaction, dehiscence, inflammation, abscess formation, the Hollander Wound Evaluation Scale or patient's satisfaction with skin closure methods. However, suturing required a longer operating time. Conclusions Closure with sutures is associated with lower risks of superficial infection and prolonged discharge than closure with staples following hip arthroplasty, but it may take more time.

Staples Versus Sutures For Skin Closure In Hip Arthroplasty: A Meta-Analysis And Systematic Review

Objective: The purpose of this present study was to estimate complication and other outcomes associated with staples and sutures closure after hip arthroplasty through meta- analysis techniques and system review. Methods: We searched for articles on EMBASE, PubMed, Medline, Web of Science and Cochrane Library. Eligibility of the searched trials. Cochrane Collaboration's Review Manager software is used to perform meta-analysis.Results: Four randomized controlled trials and one retrospective cohort trial chosen into our study. Our study indicated that the risk of infection and prolonged discharge higher with staples than with sutures for skin closure after hip arthroplasty. Meanwhile, there was no significant difference in allergic reaction, dehiscence, inflammation, abscess formation, Hollander Wound Evaluation Score and patient's satisfaction with skin closure methods between the two groups after hip arthroplasty. However, the suture group may require additional operating time.Conclusions: Closure with suture have a lower risk of infection and prolonged discharge when compared with staples skin closure in hip arthroplasty, while it may take more time.

Post-operative Complications of Patients Underwent Mastoidectomy at Tertiary Care Hospital

Aim: To analyze the post mastoidectomy complications in patients presenting at tertiary care hospital. Methods: This case series study was conducted at Department of ENT, DG Khan Hospital, DG Khan from March 2020 to September 2020 over the period of 6 months. Total 65 patients came for open cavity mastoidectomy either male or female having age between 20-60 years were selected for this study. Results: In present study 65 patients had undergone open cavity mastoidectomy. Mean age of the patients was 39.95 ± 12.57 years. Out of 65 patients, cavity complications was found in 20 (31%) patients. Among the 20 patients who had cavity problems, the most common problem was prolonged discharge found in 19 (95%) patients followed by accumulation of wax in the cavity was found in 5 (25%) patients, Vertigo persisting beyond the immediate postoperative period was found in 3 (15%) patients, perichondritis of pinna was seen in 1 (5%) patients, development of facial palsy was found in 5 (50%) patients, recurrent cholesteatoma was found in 3 (15%) patients and wound infection was found in 2 (10%) patients. Conclusion: Results of present study showed higher rate of post operative complications after mastoidectomy. Sclerotic mastoid was most common. Higher rate of complications was seen after 40th decade of life. Most of the patients were male as compared to female. Prolonged discharge was the most common problem.

Investigation of alternative materials as bifunctional catalysts for electrochemical applications

A lab-scale custom made Zinc-Air battery cell was manufactured and tested with a variety of cathode catalysts. MnO2 has been examined both as an Oxygen Reduction Reaction (ORR) and Oxygen Evolution Reaction (OER) catalyst, with more promising results as an ORR catalyst. MnO2 as well as a combination of MnO2 and MWCNTs (MOCN-10) has been examined in this work. In addition, two different Metal Organic Frameworks (MOFs), specifically HKUST-1 and MOF-74, based on Cu and Ni, respectively, were investigated as an alternative and novel cathode catalyst directly on the battery cell. A power output of 20 mW·cm-2 was achieved by using MOCN-10, along with stability in prolonged discharge cycling at 5 mA·cm-2. Furthermore MOF-loaded battery has demonstrated astonishing performance in pulse cycling for more than 120 hours. Moreover no dendrite formation was observed during long term pulse cycling.

Analysis of compressive strength of concrete prepared by triplemixing technology depending on both the discharge and curing time

Compressive strength of concrete having recycled concrete aggregate is influenced by the properties and amount of those aggregate. The worse quality of RCA can be eliminated by specific mixing approach. Practical mixing and delivery of concrete could affect the properties of ready concrete due to prolonged time. In this paper, both the fly ash and fine fraction of recycled concrete were used to improve the quality of concrete due to coating of RCA, while the triple mixing technology was applied for this purpose. The compressive strength is evaluated from two aspects: the curing time (2, 28 and 90 days) and discharge time (0, 45 and 90 minutes after mixing) with attention being paid to the type of aggregate and the type of coating material. When using triple mixing technology, prolonged discharge time brings only small effect on the compressive strength (up to 12%) both in positive and negative way, depending on kind of coating material.

Dexmedetomidine Sedation With and Without Midazolam for Third Molar Surgery

Twenty-four patients were randomly divided into 2 groups. Intraoperatively, one group received a continuous intravenous infusion of dexmedetomidine alone, whereas the other received a continuous dexmedetomidine infusion plus a small dose of midazolam. Early measurements of patient anxiety and psychomotor performance were lower in patients who had received midazolam. This difference was not seen later in the appointment. An amnesic effect was observed in those patients who received midazolam. This effect, however, did not translate into increased patient satisfaction in the group receiving midazolam. Our findings suggest a prolonged discharge time for patients who had been given midazolam that may be clinically significant. Overall, dexmedetomidine showed an unpredictable sedative response and may be less practical than more common alternatives for oral surgery procedures.
