Theory And Experiment

Using a method described previously (Baxter et al. 1966), an experimental study has been made of the time distribution of energy from the shower front of large extensive air showers detected by the Haverah Park 500-m array. Data are given on the mean time of arrival of energy in showers at axial distances over the range 250–950 m for all zenith angles, while average time distributions of the energy in the shower front are presented for some typical distance and zenith angle intervals. Experimental observations are compared with a theoretical prediction; a real discrepancy appears to exist between theory and experiment since about 25% more energy is observed in the 25 ns after the first detectable signal than is predicted. The result suggests a higher or more concentrated origin for muons than normally assumed.Assessment of measurement errors, particularly those arising from the sampling of a diffuse shower front by detectors of finite size, suggests that no intrinsic differences in the properties of the majority of air showers have yet been detected by this method.

The authors present sixteen patients with congenital kyphosis treated by posterior spinal arthrodesis. A homologous or autogenous iliac bone graft was used. The patients walked with Risser-Cotrel body cast in the 6 months of postoperatory period. The mean time of follow-up was 58,25 months and the mean age of the patients at time of surgery was 9,3 years. The mean angular value of the congenital kyphosis before surgery was 50,44º Cobb and after ther surgery it was 46,94º Cobb. One of the patients who had curve of 69º Cobb, presented pseudoarthrosis. The final results were good in 10, regular in 4 and bad in 2 patients. The need of the diagnostic and precocious treatment is recommended by authors.

Abstract Aim To improve the efficiency of intraoperative hand trauma x-ray review, introduce a scoring system for quality of fixation achieved and use this as an education and feedback tool for trainees. Method A large QI project in 2019 demonstrated that intra-operative images taken using the mini C-arm were not being reviewed. In March 2020 the first QI cycle introduced an Access database to ensure that as cases were removed from the trauma board, they were added to a review list. Each x-ray was also scored in the trauma meeting (good, acceptable, poor) to assess the radiographic quality of fixation. The second QI cycle identified the named surgeon for each case, allowing surgeon specific feedback. Finally, we trained all qualified users of the mini C-arm to upload their own images after each case, reducing the mean time to upload. Results This QI project has improved the review rate of mini C-arm images from 30% to 100% and every x-ray is scored. The mean time to review images has reduced from 4 days to less than 24 hours. All trainees can access their scores for imaged hand and wrist trauma and receive written constructive feedback. Conclusions This project ensures appropriate and prompt review of all hand and wrist trauma cases allowing early identification of any concerns. All x-rays are scored, and this process acts as an educational prompt in the trauma meeting. A final report can be printed for each trainee which can be uploaded to their portfolio to document their surgical progress.

Abstract Aim The aim of this study was to assess the perioperative pathway and outcomes of trauma laparotomy during a one-year period in a newly established Major Trauma Centre in Northern Ireland. Method Retrospective review of a trauma registry undertaken at the Belfast Royal Victoria Hospital between August 2019 and August 2020. Results During this one-year period, there were a total of 17 trauma laparotomies, with a female-to-male ratio of 6:11, and a mean age of 38.9 years. 15 of 17 cases were due to blunt trauma, with only 2 cases of penetrating trauma. Of trauma laparotomies, 8 were performed during day-time hours (0801-1800), 4 during evening-hours (1801-0000), and 5 during night-time hours (0001-0800). One perioperative death was recorded. The mean time to CT from arrival to ED was 34 minutes (national target of 30 minutes). The mean time until final report was 477 minutes (national target of &lt; 24 hours). The decision to proceed to trauma laparotomy was made prior to the final report in 9 cases. The mean length of inpatient stay for trauma laparotomy patients was 23.3 days, with a mean of 8.9 days spent in critical care. Conclusions This review provides an overview of provision of care for patients who underwent trauma laparotomies in Royal Victoria Hospital MTC and identifies areas for improvement. We plan to prospectively review outcomes following the opening of the Major Trauma Ward on 7th September 2020 and the implementation of the Northern Ireland Major Trauma Network Bypass protocol on 26th October 2020.

Objective: To describe the technique and results of mucosectomy; A surgical technique that is easy to perform, and has a lower morbidity and complication rate as compared to standard appendectomy in cases of complicated appendicitis. Study Design: Quasi-experimental study. Place and Duration of Study: Surgical - A Unit, Ayub Teaching Hospital, in Abbottabad, from Mar 2017 to Mar 2019. Methodology: Patients included were those who presented with appendicular mass, phlegmon, recurrent appendicitis, appendicitis in uncommon locations, presence of adhesions, those cases of appendicular mass and phlegmon which was either not responding to medical treatment, or diagnosed per operatively being clinically not palpable or not seen on ultrasound. Per operative and post-operative variables were documented and analyzed. In mucosectomy, thesubserosal portion of the appendix i-emuscularis and mucosa of the appendix was dissected out from the serosa after ligation of the appendicular base, or ligation done after delivering the appendix out of the serosa. The serosa that was adherent to the surrounding gut, omentum or other viscera was left intact. Results: A total of 192 patients were included in this study, half of which underwent standard appendectomy and a mucosectomy was performed on the rest. The mean time of surgery was 30 ± 1.2min as compared to the standard appendectomy group (55min ± 3.6). More than half of the patients undergoing standard appendectomy required extension of the incision (56.2%), only 8% required so from those on whom mucosectomy was performed. Per operative hemorrhage was seen in 32.2%, however inmucosectomy group only 1%.

In Different surfactants in combination with some inorganic salts were used to improve wetting behaviors of coal dust in this paper. It shows that wetting capability of the coal dust could be improved by addition of surfactant. The improvement due to surfactant use is like: JFC>OP>SDBS. In the mean time, the improvement of the inorganic salts is like: Na2SiO3>Na2SO4>CaCl2>NaCl. The further investigation demonstrates that the more Na2SO4is used, the better wetting of coal dust is bility is.

Daily Maintenance Dose

SummaryDue to large inter-individual variations, the dose of vitamin K antagonist required to target the desired hypocoagulability is hardly predictible for a given patient, and the time needed to reach therapeutic equilibrium may be excessively long. This work reports on a simple method for predicting the daily maintenance dose of fluindione after the third intake. In a first step, 37 patients were delivered 20 mg of fluindione once a day, at 6 p.m. for 3 consecutive days. On the morning of the 4th day an INR was performed. During the following days the dose was adjusted to target an INR between 2 and 3. There was a good correlation (r = 0.83, p<0.001) between the INR performed on the morning of day 4 and the daily maintenance dose determined later by successive approximations. This allowed us to write a decisional algorithm to predict the effective maintenance dose of fluindione from the INR performed on day 4. The usefulness and the safety of this approach was tested in a second prospective study on 46 patients receiving fluindione according to the same initial scheme. The predicted dose was compared to the effective dose soon after having reached the equilibrium, then 30 and 90 days after. To within 5 mg (one quarter of a tablet), the predicted dose was the effective dose in 98%, 86% and 81% of the patients at the 3 times respectively. The mean time needed to reach the therapeutic equilibrium was reduced from 13 days in the first study to 6 days in the second study. No hemorrhagic complication occurred. Thus the strategy formerly developed to predict the daily maintenance dose of warfarin from the prothrombin time ratio or the thrombotest performed 3 days after starting the treatment may also be applied to fluindione and the INR measurement.

Purpose To retrospectively determine the rate of death occurring within 14 and 30 days of systemic anticancer therapy (SACT), compare this against a previous audit and benchmark results against other cancer centres. Secondly, to determine if the introduction of immune checkpoint inhibitors (ICI), not available at the time of the initial audit, impacted mortality rates. Method All adult solid tumour and haematology patients receiving SACT at an Australian Regional Cancer Centre (RCC) between January 2016 and July 2020 were included. Results Over a 55-month period, 1709 patients received SACT. Patients dying within 14 and 30 days of SACT were 3.3% and 7.0% respectively and is slightly higher than our previous study which was 1.89% and 5.6%. Mean time to death was 15.5 days. Males accounted for 63.9% of patients and the mean age was 66.8 years. 46.2% of the 119 patients dying in the 30 days post SACT started a new line of treatment during that time. Of 98 patients receiving ICI, 22.5% died within 30 days of commencement. Disease progression was the most common cause of death (79%). The most common place of death was the RCC (38.7%). Conclusion The rate of death observed in our re-audit compares favourably with our previous audit and is still at the lower end of that seen in published studies in Australia and internationally. Cases of patients dying within 30 days of SACT should be regularly reviewed to maintain awareness of this benchmark of quality assurance and provide a feedback process for clinicians.
