External rotation method for reduction of acute anterior dislocation of shoulder

Introductions: Many different techniques of reduction of acute anterior shoulder dislocation have been described. The aim of this study was to evaluate the effectiveness of external rotation method for reduction of acute anterior shoulder dislocation. Methods: Fifty-one patients with acute anterior shoulder dislocations with or without greater tuberosity fracture were reduced during a period from January 2013 to January 2015. The external rotation method was used as an initial reduction method performed by orthopaedic surgeon on call or residents. Data sheets completed by the orthopaedic surgeon on call or residents were evaluated with regard to the type of dislocation, the effectiveness of the procedure in achieving reduction, the need for premedication, the ease of performing the reduction, and complications, if any. Results: There were 42 male and nine female patients between 18 to 78 years. Among 51 patients, 49 had successful reduction. No premedication was required in 33 patients who had a successful reduction, and the average time required for reduction in 23 patients was within two minutes whereas 20 patients reduced within five minutes. Only four patients reported severe pain during the process of reduction. The method was not successful in two patients with subcoracoid dislocation associated with displaced fracture of the greater tuberosity. Conclusions: External rotation method is reliable, safe, simple and relatively painless method for reduction of acute anterior shoulder dislocation. Keywords: acute anterior shoulder dislocation, external rotation method, painless reductionÂ

Three lateral divergent pinning for displaced supracondylar humerus fractures in children

Introductions: Cross or two lateral pinnings are the most commonly doneprocedures for displaced supracondylar humerus fractures in children. Acrossed pin is biomechanically stable than lateral pins, but associated withrisk of iatrogenic ulnar nerve injury. Recent studies have shown stable fixationwith three lateral pin construct. The purpose of this study was to evaluate theefficacy of three lateral divergent pinning for displaced supracondylar humerusfractures.Methods: Thirty five children with Gartland types III were treated betweenNovember 2012 and November 2013. Closed reduction and three lateraldivergent pinning was done with image intensifier guidance. Patients werefollowed up for minimum 6 months. Radiological assessment was done to seeunion, proper pin placement and loss of reduction. Clinically, patients wereassessed by using Flynn criteria.Results: There were 24 (68.6%) male and 11 (31.4%) female children between2 to 13 years of age with displaced supracondylar fractures, left side 26 (74.3%) and right nine (25.7%) cases. All were successfully managed with closed reduction and three lateral divergent pins within 2-6 days of injury. One radial and one median nerve palsies sustained at injury recovered spontaneously. No iatrogenic nerve injuries occurred. A comparison of perioperative and final radiographs revealed no loss of reduction. Twenty-seven excellent, five good, two fair and one poor results on Flynn’s grading. One patient had a superficial pin-tract infection.Conclusions: Closed reduction with three lateral divergent pins is safe for stablefixation of displaced supracondylar humeral fractures in children.Keywords: children, humerus, percutaneous pinning, supracondylar fractur

Nitrogen uptake and economics of black rice (Oryza sativa L. indica) under different crop geometries and nitrogen management practices

Black rice has more antioxidants than any other rice variety.  It is considered to have multiple benefits in human health due to the presence of different antioxidants. A field experiment was conducted during rainy season of 2015-2016 to assess the nitrogen uptake, use efficiency and economics of black rice production under different crop geometry and nitrogen (N) management practices in Rampur, Chitwan, Nepal. The experiment was laid out in strip plot design with three replications. The experiment consisted of  treatment combination of three crop geometry (20 cm × 20 cm, 20 cm × 15 cm and 15 cm × 15 cm) in vertical plots and three nitrogen management practices (N level: 30 kg N ha-1, 60 kg N ha-1, and LCC based N-management) in horizontal plots. The results showed that the highest N uptake was recorded from closer spacing (15 cm × 15 cm) with LCC based N management. The net return and B: C ratios were higher at a closer spacing of 15 cm × 15 cm with LCC based N management and closer spacing of 15 cm × 15 cm with N application of 60 kg ha-1. The overall analysis revealed that LCC based N management under closer crop geometry (15 cm × 15 cm) was the best management practices because of high nitrogen uptake and highest monetary return with B: C ratio of 5.76

Orthopaedic services during COVID-19 lockdown at Patan Hospital, Nepal

Introduction: The COVID-19 pandemic has paralyzed the world, including elective health care services. To prevent the spread of infection, most countries have gone into lockdown and adjustments have been made to provide urgent medical care, including Orthopaedic services. In accordance with the guidelines from worst affected countries and neighboring India, Patan Hospital followed instructions from Ministry of Health and Population to provide only urgent and semi-urgent Orthopaedic services. This study aims to audit the patient profile during lockdown so as to have a clearer picture, which will enable us to be prepared for similar epidemic in the future. Method: All patients admitted to the Orthopaedic ward of Patan hospital from 24 March to 27 April 2020, during the lockdown, were included. Clinical profile, including cause of admission, management, hospital stay were descriptively analyzed. Ethical approval was obtained. Result: Out of 44 admissions, there were male 27 and female 17. Trauma cases were 38, and 18 were in age group 20-26 years. Admission due to infections were four. Conservative management were done in seven while 33 were treated surgically, out of which 30 accounted for trauma. Average 6.14 days hospital stay, range 1-22 days. Conclusion: Trauma comprised of major bulk of patients seeking urgent Orthopaedic care. Hospital needs to be prepared with necessary measures to ensure safety of health care workers and yet provide urgent Orthopaedic services. Keyword: COVID-19, lockdown, orthopaedic

Visualisation of Rouviere’s Sulcus during Laparoscopic Cholecystectomy

Introduction: Safe dissection of Calot’s Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere’s sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot’s triangle. Methods: This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere’s sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized. Results: A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere’s sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. Conclusions: Rouviere’s Sulcus is an important extra biliary land mark for safe dissection of Calot’s triangle during laparoscopic cholecystectomy.  Keywords: Rouviere’s Sulcus, laparoscopic cholecystectomy, bile duct injury

Effect of Village-wide Use of Long-Lasting Insecticidal Nets on Visceral Leishmaniasis Vectors in India and Nepal: A Cluster Randomized Trial

Visceral leishmaniasis (VL) is a vector-borne disease causing at least 60,000 deaths each year amongst an estimated half million cases, and until recently there have been no significant initiatives to reduce this burden. However, in 2005, the governments of India, Bangladesh and Nepal signed a memorandum of understanding at the World Health Assembly in Geneva for the elimination of the disease by 2015. In the absence of an effective vaccine, the program will rely on the active detection and prompt treatment of cases throughout the endemic region, combined with a recurrent indoor residual spraying (IRS) of all villages at risk. Vector control programs based on IRS are notorious for failing to maintain comprehensive spray coverage over time owing to logistical problems and lack of compliance by householders. Long-lasting insecticidal nets (LNs) have been postulated as an alternative or complement to IRS. Here we describe how comprehensive coverage of LN in trial communities reduced the indoor density of sand flies by 25% compared to communities without LNs. This provides an indication that LNs could be usefully deployed as a component of the VL control program in the Indian subcontinent

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.
