Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries. Br J Surg 2023; 110:804-817. [PMID: 37079880 PMCID: PMC10364528 DOI: 10.1093/bjs/znad092] [Citation(s) in RCA: 14] [Impact Index Per Article: 14.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/16/2023] [Revised: 03/03/2023] [Accepted: 03/06/2023] [Indexed: 04/22/2023]
Abstract
BACKGROUND Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. METHODS This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low-middle-income countries. RESULTS In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of 'single-use' consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low-middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. CONCLUSION This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high- and low-middle-income countries.

A Simple Technique to Remove an Incarcerated Ceramic Liner in Revision Hip Arthroplasty. Arthroplast Today 2023; 21:101142. [PMID: 37205270 PMCID: PMC10185739 DOI: 10.1016/j.artd.2023.101142] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Revised: 01/27/2023] [Accepted: 04/01/2023] [Indexed: 05/21/2023] Open
Abstract
Extraction of a well-fixed ceramic liner during revision total hip arthroplasty can be technically challenging, particularly when acetabular fixation screws prevent en bloc removal of the shell and insert without causing collateral damage to the adjacent pelvic bone. It is also important to remove the ceramic liner intact, as ceramic debris left in the joint may cause third body wear with premature articular wear of the revised implants. We describe a novel technique to extract an incarcerated ceramic liner when previously described strategies prove ineffective. Knowledge of this technique will help surgeons avoid unnecessary damage to the acetabular bone and optimize prospects for stable implantation of revision components.

The composition of cell-based therapies obtained from point-of-care devices/systems which mechanically dissociate lipoaspirate: a scoping review of the literature. J Exp Orthop 2022; 9:103. [PMID: 36209438 PMCID: PMC9548462 DOI: 10.1186/s40634-022-00537-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/25/2022] [Accepted: 09/15/2022] [Indexed: 11/15/2022] Open
Abstract
Purpose Cell-based therapies using lipoaspirate are gaining popularity in orthopaedics due to their hypothesised regenerative potential. Several ‘point-of-care’ lipoaspirate-processing devices/systems have become available to isolate cells for therapeutic use, with published evidence reporting their clinical relevance. However, few studies have analysed the composition of their ‘minimally-manipulated’ cellular products in parallel, information that is vital to understand the mechanisms by which these therapies may be efficacious. This scoping review aimed to identify devices/systems using mechanical-only processing of lipoaspirate, the constituents of their cell-based therapies and where available, clinical outcomes. Methods PRISMA extension for scoping reviews guidelines were followed. MEDLINE, Embase and PubMed databases were systematically searched to identify relevant articles until 21st April 2022. Information relating to cellular composition and clinical outcomes for devices/systems was extracted. Further information was also obtained by individually searching the devices/systems in the PubMed database, Google search engine and contacting manufacturers. Results 2895 studies were screened and a total of 15 articles (11 = Level 5 evidence) fulfilled the inclusion criteria. 13 unique devices/systems were identified from included studies. All the studies reported cell concentration (cell number regardless of phenotype per millilitre of lipoaspirate) for their devices/systems (range 0.005–21 × 106). Ten reported cell viability (the measure of live cells- range 60–98%), 11 performed immuno-phenotypic analysis of the cell-subtypes and four investigated clinical outcomes of their cellular products. Only two studies reported all four of these parameters. Conclusion When focussing on cell concentration, cell viability and MSC immuno-phenotypic analysis alone, the most effective manual devices/systems were ones using filtration and cutting/mincing. However, it was unclear whether high performance in these categories would translate to improved clinical outcomes. Due to the lack of standardisation and heterogeneity of the data, it was also not possible to draw any reliable conclusions and determine the role of these devices/systems in clinical practice at present.

Abstract
AIMS Total hip arthroplasty (THA) and total knee arthroplasty (TKA) are common orthopaedic procedures requiring postoperative radiographs to confirm implant positioning and identify complications. Artificial intelligence (AI)-based image analysis has the potential to automate this postoperative surveillance. The aim of this study was to prepare a scoping review to investigate how AI is being used in the analysis of radiographs following THA and TKA, and how accurate these tools are. METHODS The Embase, MEDLINE, and PubMed libraries were systematically searched to identify relevant articles. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for scoping reviews and Arksey and O'Malley framework were followed. Study quality was assessed using a modified Methodological Index for Non-Randomized Studies tool. AI performance was reported using either the area under the curve (AUC) or accuracy. RESULTS Of the 455 studies identified, only 12 were suitable for inclusion. Nine reported implant identification and three described predicting risk of implant failure. Of the 12, three studies compared AI performance with orthopaedic surgeons. AI-based implant identification achieved AUC 0.992 to 1, and most algorithms reported an accuracy > 90%, using 550 to 320,000 training radiographs. AI prediction of dislocation risk post-THA, determined after five-year follow-up, was satisfactory (AUC 76.67; 8,500 training radiographs). Diagnosis of hip implant loosening was good (accuracy 88.3%; 420 training radiographs) and measurement of postoperative acetabular angles was comparable to humans (mean absolute difference 1.35° to 1.39°). However, 11 of the 12 studies had several methodological limitations introducing a high risk of bias. None of the studies were externally validated. CONCLUSION These studies show that AI is promising. While it already has the ability to analyze images with significant precision, there is currently insufficient high-level evidence to support its widespread clinical use. Further research to design robust studies that follow standard reporting guidelines should be encouraged to develop AI models that could be easily translated into real-world conditions.

Abstract
Abstract
Introduction
NHS England generates over 20 million tonnes of CO2 per year, representing 4% of the nation's greenhouse gas emissions. One third of all hospital waste comes from operating theatres. Our aim was to investigate the degree of knowledge of sustainable waste segregation amongst theatre staff in an elective orthopaedic centre and identify ways to improve their waste segregation practice.
Methods
Over a one-week period, 20 randomly selected theatre staff of different roles, completed a questionnaire asking them which disposal bin 11 commonly used orthopaedic theatre items should be placed in – general waste or recycling. After initial data collection, posters specifically identifying recyclable items were created and displayed in each operating theatre. Following this intervention, data was re-collected from another 20 randomly selected theatre staff using the same questionnaire.
Results
Results from the initial questionnaire showed general waste and recyclable items were correctly identified by staff in 65% (78/120 responses) and 59% (59/100 responses), respectively. Following the educational intervention, the percentage of correct responses increased to 68.3% (82/120 responses) and 85% (85/100 responses); i.e. staff knowledge of what can go into a recycling bin improved by 36%.
Conclusion
Educating staff by placing posters in the operating theatre can improve knowledge of what orthopaedic theatre items can be recycled and is a simple and effective way of producing sustainable change in surgery. Guiding and empowering individuals to exercise sustainable practice in the operating theatre will help the NHS to overcome the significant challenge of achieving net zero carbon by 2045.
Take-home message
Educating staff by placing posters in the operating theatre is a simple and effective way of improving waste segregation practice and will help the health service to overcome the significant challenge of achieving net zero carbon.

Evaluation of prognostic risk models for postoperative pulmonary complications in adult patients undergoing major abdominal surgery: a systematic review and international external validation cohort study. Lancet Digit Health 2022; 4:e520-e531. [PMID: 35750401 DOI: 10.1016/s2589-7500(22)00069-3] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Revised: 01/07/2022] [Accepted: 04/06/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Aims This international study aimed to assess: 1) the prevalence of preoperative and postoperative COVID-19 among patients with hip fracture, 2) the effect on 30-day mortality, and 3) clinical factors associated with the infection and with mortality in COVID-19-positive patients. Methods A multicentre collaboration among 112 centres in 14 countries collected data on all patients presenting with a hip fracture between 1st March-31st May 2020. Demographics, residence, place of injury, presentation blood tests, Nottingham Hip Fracture Score, time to surgery, management, ASA grade, length of stay, COVID-19 and 30-day mortality status were recorded. Results A total of 7090 patients were included, with a mean age of 82.2 (range 50–104) years and 4959 (69.9%) being female. Of 651 (9.2%) patients diagnosed with COVID-19, 225 (34.6%) were positive at presentation and 426 (65.4%) were positive postoperatively. Positive COVID-19 status was independently associated with male sex (odds ratio (OR) 1.38, p = 0.001), residential care (OR 2.15, p < 0.001), inpatient fall (OR 2.23, p = 0.003), cancer (OR 0.63, p = 0.009), ASA grades 4 (OR 1.59, p = 0.008) or 5 (OR 8.28, p < 0.001), and longer admission (OR 1.06 for each increasing day, p < 0.001). Patients with COVID-19 at any time had a significantly lower chance of 30-day survival versus those without COVID-19 (72.7% versus 92.6%, p < 0.001). COVID-19 was independently associated with an increased 30-day mortality risk (hazard ratio (HR) 2.83, p < 0.001). Increasing age (HR 1.03, p = 0.028), male sex (HR 2.35, p < 0.001), renal disease (HR 1.53, p = 0.017), and pulmonary disease (HR 1.45, p = 0.039) were independently associated with a higher 30-day mortality risk in patients with COVID-19 when adjusting for confounders. Conclusion The prevalence of COVID-19 in hip fracture patients during the first wave of the pandemic was 9%, and was independently associated with a three-fold increased 30-day mortality risk. Among COVID-19-positive patients, those who were older, male, with renal or pulmonary disease had a significantly higher 30-day mortality risk.

Abstract
Neuroendocrine neoplasms represent a broad group of uncommon tumours, comprising neuroendocrine tumours, mixed neuroendocrine non-endocrine neoplasms and neuroendocrine carcinomas. While most neuroendocrine neoplasms are well differentiated and exhibit indolent disease biology with excellent treatment response, neuroendocrine carcinomas represent a rare subtype with much more aggressive tumour behaviour, minimal response to adjuvant therapy and extremely poor prognosis. Herein, we report the case of a 47-year-old man who presented with a phlegmonous ascending colonic mass and associated calcified ileocolic lymphadenopathy. He underwent emergent right hemicolectomy, which diagnosed a T4aN2b neuroendocrine carcinoma. Within a week the patient displayed rapidly progressive locoregional nodal disease and he succumbed to disease within 5 weeks. We discuss the significance of calcified abdominal lymphadenopathy on computed tomography scans of the abdomen and review the literature surrounding this rare and highly fatal malignancy.

Abstract
BACKGROUND Acidemia, is associated with reduced cardiac function in animals, but no studies showing an effect of acidemia on cardiac function in humans are reported. In the present study, we examined the effect of acidemia on cardiac function assessed with transpulmonary thermodilution technique with integrated pulse contour analysis (Pulse Contour Cardiac Output, PiCCO™) in a large cohort of critically ill patients. METHODS This was a prospective multicenter observational cross-sectional study of 297 patients from 6 intensive care units in London, England selected from all patients admitted consecutively between May 2018 and March 2019. Measurements of lowest plasma pH and concurrent assessment of cardiac function were obtained. FINDINGS There was a significant difference between two pH categories (pH ≤ 7.28 vs. pH > 7.28) for the following variables of cardiac function: SVI (difference in means 32.7; 95% CI: 21 to 45 mL/m2; p < 0.001); GEF (18; 95% CI: 11 to 26%; p < 0.001), dPmax (-331; 95% CI: -510 to -153 mmHg/s; p = 0.001), CFI (0.7; 95% CI: 0.2 to 1.3 1/min; p = 0.01) and CPI (0.09; 95% CI: 0.03 to 0.15 W/m2; p < 0.001). However, there was no significant difference in CI (0.13; 95% CI: -0.20 to 0.47 L/min/m2; p = 0.12) between the pH categories. Also, a significant relationship was found between the quantitative pH and the following variables: SVI (132; 95% CI: 77 to 188 mL/m2; p < 0.001), GEF (74.7; 95% CI: 37.1 to 112.4%; p < 0.001), dPmax (-1587; 95% CI: -2361 to -815 mmHg/s; p < 0.001), CFI (3.5; 95% CI: 0.9 to 6.1 /min; p = 0.009), CPI (0.62; 95% CI: 0.36 to 0.88 W/m2; p < 0.001) and CI (regression coefficient 1.96; 95% CI:0.45 to 3.47 L/min/m2; p = 0.01). INTERPRETATION Acidemia is associated with impaired cardiac function in seriously ill patients hospitalized in the intensive care unit supporting the potential value of early diagnosis and improvement of arterial pH in these patients. FUNDING The study was partially supported by unrestricted funds from the UCLA School of Medicine.

Abstract
BACKGROUND 80% of individuals with cancer will require a surgical procedure, yet little comparative data exist on early outcomes in low-income and middle-income countries (LMICs). We compared postoperative outcomes in breast, colorectal, and gastric cancer surgery in hospitals worldwide, focusing on the effect of disease stage and complications on postoperative mortality. METHODS This was a multicentre, international prospective cohort study of consecutive adult patients undergoing surgery for primary breast, colorectal, or gastric cancer requiring a skin incision done under general or neuraxial anaesthesia. The primary outcome was death or major complication within 30 days of surgery. Multilevel logistic regression determined relationships within three-level nested models of patients within hospitals and countries. Hospital-level infrastructure effects were explored with three-way mediation analyses. This study was registered with ClinicalTrials.gov, NCT03471494. FINDINGS Between April 1, 2018, and Jan 31, 2019, we enrolled 15 958 patients from 428 hospitals in 82 countries (high income 9106 patients, 31 countries; upper-middle income 2721 patients, 23 countries; or lower-middle income 4131 patients, 28 countries). Patients in LMICs presented with more advanced disease compared with patients in high-income countries. 30-day mortality was higher for gastric cancer in low-income or lower-middle-income countries (adjusted odds ratio 3·72, 95% CI 1·70-8·16) and for colorectal cancer in low-income or lower-middle-income countries (4·59, 2·39-8·80) and upper-middle-income countries (2·06, 1·11-3·83). No difference in 30-day mortality was seen in breast cancer. The proportion of patients who died after a major complication was greatest in low-income or lower-middle-income countries (6·15, 3·26-11·59) and upper-middle-income countries (3·89, 2·08-7·29). Postoperative death after complications was partly explained by patient factors (60%) and partly by hospital or country (40%). The absence of consistently available postoperative care facilities was associated with seven to 10 more deaths per 100 major complications in LMICs. Cancer stage alone explained little of the early variation in mortality or postoperative complications. INTERPRETATION Higher levels of mortality after cancer surgery in LMICs was not fully explained by later presentation of disease. The capacity to rescue patients from surgical complications is a tangible opportunity for meaningful intervention. Early death after cancer surgery might be reduced by policies focusing on strengthening perioperative care systems to detect and intervene in common complications.

Abstract
BACKGROUND Nepal Cleft & Burn Center, Kirtipur Hospital, Kathmandu has been providing the acute burn care since 2013 with 10 ICU beds, 32 general beds and two operating rooms. This study analyses the demographics of and early outcome in the acute burn patients. METHODS This is a descriptive retrospective study of the clinical data of acute burn patients admitted from January 1 to December 31, 2014. RESULTS There were 78 patients from 3 months to 88 years of age with a median age of 29 years. Forty six (58.9%) were females and 32 (41.1%) were males. Most of the injuries (n=57; 73%) occurred inside the house. Flame burn was the commonest mode of injury (n= 48, 61.6%). Only eleven (14.1%) patients arrived on the same day of the injury. The time elapsed was from 1 to 67 days with a median of 5 days. Only two (2.5%) patients had poured water for more than 20 minutes. Range of total body surface area (TBSA) involved was 1% to 70% with a median of 12%. Range of hospital stay was 1 to 105 days with a median of 17 days. Sixty (76.9%) patients underwent 102 surgical operations. Twenty six (33.3%) patients needed blood transfusion. A total of 15 (19.2%) patients died. None survived a burn injury of more than 40% TBSA. CONCLUSIONS Treatment of acute burn is very challenging with high mortality rate. A lot of effort is needed to change the present standard of care. Awareness programs on First Aid treatment of burn injuries together with the preventive programs focused on high risk population such as females and children in a large scale needs to be organized as soon as possible.

Abstract
Objective: To determine the prevalenceof and associated risk factors for pterygiumin the high altitude communities of the Upper Mustang region of Nepal, near the Tibet border. Materials and methods: Six villages of the Upper Mustang were selected based on the concentration of population. All subjects were permanent residents aged 16 years and older, and recruited through a household census with mobilization of local monks who had been trained as interviewers, and people were invited to attend the eye clinic for a complete examination. A cross-sectional studywas conducted which included the parameters oflaterality, severity, occupation, age, sex and altitude of residence. Results:The study population comprised 1,319 individuals of which 637 (48.29%) weremale and682 (51.71%) were female.The overall prevalence of pterygium, was 10.08% (133 of 1,319), with 42.86% for males and 57.14% for females. The mean age of the subjects was45.83 years and the mean SD 17.94. The majority of the subjects had a unilateral pterygium. The right eye(n=63) was predominately affected, in 57.80% of the total subjects. Farmers and construction workers, which comprised of 36.09% and 28.57% respectively, had a higher prevalence of pterygium. The most affected age group was the 66 to 75 years group (n=31: 23.31%). The prevalence increased linearly with age. The severe Grade III and Grade IV pterygium were predominant in the age group of 56-65 years, comprising 28.58% of all the cases;the less severe Grade I was also predominant in the same age group,with 23.56%, and Grade II (0-2 mm) was predominant in the age group of 46-55, with 31.03%. Conclusion: Pterygiumisa significant public health problem in the high altitude communities of Nepal. It is more prevalent amongst the farmers than in the other professionals.

Abstract
BACKGROUND Prophylactic aspirin has been considered to be beneficial in reducing the risks of heart disease and cancer. However, potential benefits must be balanced against the possible harm from side effects, such as bleeding and gastrointestinal (GI) symptoms. It is particularly important to know the risk of side effects when aspirin is used as primary prevention--that is when used by people as yet free of, but at risk of developing, cardiovascular disease (CVD) or cancer. In this report we aim to identify and re-analyse randomised controlled trials (RCTs), systematic reviews and meta-analyses to summarise the current scientific evidence with a focus on possible harms of prophylactic aspirin in primary prevention of CVD and cancer. OBJECTIVES To identify RCTs, systematic reviews and meta-analyses of RCTs of the prophylactic use of aspirin in primary prevention of CVD or cancer. To undertake a quality assessment of identified systematic reviews and meta-analyses using meta-analysis to investigate study-level effects on estimates of benefits and risks of adverse events; cumulative meta-analysis; exploratory multivariable meta-regression; and to quantify relative and absolute risks and benefits. METHODS We identified RCTs, meta-analyses and systematic reviews, and searched electronic bibliographic databases (from 2008 September 2012) including MEDLINE, Cochrane Central Register of Controlled Trials, Database of Abstracts of Reviews of Effects, NHS Centre for Reviews and Dissemination, and Science Citation Index. We limited searches to publications since 2008, based on timing of the most recent comprehensive systematic reviews. RESULTS In total, 2572 potentially relevant papers were identified and 27 met the inclusion criteria. Benefits of aspirin ranged from 6% reduction in relative risk (RR) for all-cause mortality [RR 0.94, 95% confidence interval (CI) 0.88 to 1.00] and 10% reduction in major cardiovascular events (MCEs) (RR 0.90, 95% CI 0.85 to 0.96) to a reduction in total coronary heart disease (CHD) of 15% (RR 0.85, 95% CI 0.69 to 1.06). Reported pooled odds ratios (ORs) for total cancer mortality ranged between 0.76 (95% CI 0.66 to 0.88) and 0.93 (95% CI 0.84 to 1.03). Inclusion of the Women's Health Study changed the estimated OR to 0.82 (95% CI 0.69 to 0.97). Aspirin reduced reported colorectal cancer (CRC) incidence (OR 0.66, 95% CI 0.90 to 1.02). However, including studies in which aspirin was given every other day raised the OR to 0.91 (95% CI 0.74 to 1.11). Reported cancer benefits appeared approximately 5 years from start of treatment. Calculation of absolute effects per 100,000 patient-years of follow-up showed reductions ranging from 33 to 46 deaths (all-cause mortality), 60-84 MCEs and 47-64 incidents of CHD and a possible avoidance of 34 deaths from CRC. Reported increased RRs of adverse events from aspirin use were 37% for GI bleeding (RR 1.37, 95% CI 1.15 to 1.62), between 54% (RR 1.54, 95% CI 1.30 to 1.82) and 62% (RR 1.62, 95% CI 1.31 to 2.00) for major bleeds, and between 32% (RR 1.32, 95% CI 1.00 to 1.74) and 38% (RR 1.38, 95% CI 1.01 to 1.82) for haemorrhagic stroke. Pooled estimates of increased RR for bleeding remained stable across trials conducted over several decades. Estimates of absolute rates of harm from aspirin use, per 100,000 patient-years of follow-up, were 99-178 for non-trivial bleeds, 46-49 for major bleeds, 68-117 for GI bleeds and 8-10 for haemorrhagic stroke. Meta-analyses aimed at judging risk of bleed according to sex and in individuals with diabetes were insufficiently powered for firm conclusions to be drawn. LIMITATIONS Searches were date limited to 2008 because of the intense interest that this subject has generated and the cataloguing of all primary research in so many previous systematic reviews. A further limitation was our potential over-reliance on study-level systematic reviews in which the person-years of follow-up were not accurately ascertainable. However, estimates of number of events averted or incurred through aspirin use calculated from data in study-level meta-analyses did not differ substantially from estimates based on individual patient data-level meta-analyses, for which person-years of follow-up were more accurate (although based on less-than-complete assemblies of currently available primary studies). CONCLUSIONS We have found that there is a fine balance between benefits and risks from regular aspirin use in primary prevention of CVD. Effects on cancer prevention have a long lead time and are at present reliant on post hoc analyses. All absolute effects are relatively small compared with the burden of these diseases. Several potentially relevant ongoing trials will be completed between 2013 and 2019, which may clarify the extent of benefit of aspirin in reducing cancer incidence and mortality. Future research considerations include expanding the use of IPD meta-analysis of RCTs by pooling data from available studies and investigating the impact of different dose regimens on cardiovascular and cancer outcomes.

Abstract
Phylloides tumor constitutes less than 1% of all breast tumors and 2 - 3% of fibroepithelial breast tumors. Several histological parameters should be evaluated, including stromal cellularity, atypia, mitoses, stromal overgrowth, infiltrative borders, and presence or absence of necrosis. Here we report a case of a 60 years- old female who presented with left breast lump. Fine needle aspiration cytology was done which suggested epithelial hyperplasia with fibrocystic changes. Biopsy was performed which showed predominance of stromal hypercellularity with proliferation of spindle cells (no atypia, mitosis and stromal overgrowth were noticed). However, a focus showed proliferation of discohesive tumor cells arranged singly and in single file. A diagnosis of benign phylloides tumor with foci of invasive lobular carcinoma was made. The diagnosis was confirmed with IHC which showed intense 80%positivity for estrogen and progesterone receptor and spindle cells showing positivity for bcl-2. In situ lobular carcinoma component was not observed. DOI: http://dx.doi.org/10.3126/jpn.v4i7.10321 Journal of Pathology of Nepal (2014) Vol. 4, 597-599

Abstract
BACKGROUND Sepsis is a major cause of mortality and morbidity in newborns affecting both developed and developing countries accounting a quarter around one million deaths per annum. OBJECTIVE This study was aimed to assess the prevalence of neonatal sepsis, culture isolates, pattern, antibiotic sensitivity and drug prescribing pattern. METHODS In present prospective study, 48 neonates admitted in pediatric ward from January to March 2011 of Dhulikhel Hospital were included. The gestation age, onset of sepsis, culture isolates, antibiotic sensitivity pattern and drug prescribing pattern were studied. Environmental air sampling of NICU (Neonatal Intensive Care Unit) was done by settle plate method for microbial examination. RESULT Among 48 neonates, 23 (47.92%) neonates were culture positive with predominant isolates of Klebsiella oxytoca 11(47.83%), Pseudomonas sp. 4(17.39%), Methicillin Resistant Staphylococcus Aureus (MRSA) 3(13.04%) and single case of Enterobacter spp. In environmental samples, K. oxytoca and Enterobacter sp. were isolated. Amikacin, Imepeneum and Ciprofloxacin were sensitive whereas Ampicillin in combination with Cloxacillin, Ampicillin, Aztreonam were resistant for Klebsiella. oxytoca. Amikacin, Ceftazidime and Imipenuem were sensitive to Enterobacter spp. The single or combinations of resistant antibiotics were found to be prescribed. CONCLUSION The emerging antibiotic resistances among the culture isolates and coherence with environmental samples were observed. Hence, special measures are imperative for reducing environmental contamination and the rational usage of antibiotics for preventing the infection and emerging antibiotic resistance. The study recommends need of the antibiotic policy to curb the present scenario.

Abstract
BACKGROUND Rotavirus is the most common cause of life threatening gastroenteritis in infants and young children in the world. The objective of the study is to find out current trends and incidents of rotavirus, including other enteropathogens related with children diarrhoea and lastly identify the most common rotavirus serotypes that circulate in Nepal. METHODS A total of 1721 stool samples from less than 5 years of children were collected. Rotavirus in the stool samples were detected by Enzyme Immuno Assay (EIA) and strains were genotyped by Reverse-Transcription Polymerase Chain Reaction (RT-PCR). Bacteria and parasites were detected by following standard microbiological procedures. RESULTS In between 2009 to 2010, of the total 1721, the prevalence of rotavirus was 24.7%. Of them, 906 (52.6%) were collected in the year 2009 and 815(47.5%) in the year 2010. Rotavirus was frequently detected in inpatients (31.6%) than outpatient (16.8%). Rotavirus detection was higher in female (26.4%) than male (23.7%). The prevalence was seen higher in age group 0-23 months in both years. Among six different bacterial isolates, Escherichia coli was most frequently isolated (6.5%). Similarly, Giardia lamblia (1.3%) was most common among six different parasites detected. A total of rotavirus positive 425 stool samples were detected over 2 years (2009-230, and 2010-195), G12P6 was the predominant strain circulating in both (45% in 2009 and 28% in 2010) years. G9P6 emerged in 2010 (6%). There were significant numbers of mixed infections (14.0% in 2009 and 29.8% in 2010). Thirty five samples were partially typed and 15 were completely untyped over the two year period. CONCLUSIONS The study helps comprehend the prevalence of rotavirus along with other intestinal pathogens including bacteria and parasites. Major genotypes of rotavirus are also introduced in the study.

Abstract
Introduction: Rotavirus is one of the most common causes of acute gastroenteritis among infants and young children. The spread of rotavirus infection in pediatric wards can cause acute diarrhoea during hospitalization, and in turn, prolong hospitalization or need, rehospitalization. The aim of the study was to determine the prevalence of nosocomial infection due to rotavirus and other causal organisms among children less than 5 years of age. Methodology: A cross-sectional study between November 2009 and May 2010 was conducted among 96 pediatric patients in children hospital, Nepal. Stool samples were collected during hospitalization and up to 3 days after discharge from the hospital. Rotavirus antigens were detected by EIA and standard microbiological procedure were applied for other enteric pathogens. Results: The prevalence of nosocomial infection due to rotavirus was 30.2% (29/96). Of them, 16 (55.17%) of the 29 children with nosocomial infection during hospitalization and/or up to 72 hours after discharge developed diarrhoea. The prevalence of symptomatic cases of nosocomial infection was 55.17% (16/29), which involved 16.7% (16/96) of the study subjects, showing a prevalence of 44.82% (13/29) for asymptomatic nosocomial infection consisted of 13.54% (13/96) of the total subjects. Eleven of the 16 symptomatic subjects of nosocomial infection were affected by diarrhoea during hospitalization and five subjects after discharge. Bacteria (8.3%) and protozoa (5.2%) agents were also causing nosocomial infection in children. Conclusions: Children attending hospital may asymptomatically carry enteric pathogens and potentially act as source of nosocomial infection. Due to the relatively high frequency of nosocomial infection in the Children Hospital of Nepal, it is necessary to follow strictly hygienic rules such as isolation of patients with diarrhoea and hand-washing before and after the examination of each patient and cleaning the examination instruments after use in each patient.

Abstract
Leiomyoma is a benign tumor showing smooth muscle differentiation. Leiomyoma in the nasal cavity is a rare entity which can present with common nasal symptoms. We report a case of 19 years old male patient with nasal leiomyoma. The patient presented with recurrent episodes of nasal obstruction and epistaxis. On nasoendoscopy, there was a single grayish polypoidal mass in the right middle meatus which bled on touch. CT-scan of nose and paranasal sinus showed homogenous opacity indistinguishable from the right middle turbinate. The mass was excised endoscopically. There is no recurrence a year after the endoscopic excision of the nasal leiomyoma. Nasal leiomyoma carries a good prognosis after complete excision.Key words: endoscopic excision, leiomyoma, nasal cavity
