Association between lung function and dyspnoea and its variation in the multinational Burden of Obstructive Lung Disease (BOLD) study

BACKGROUND

Dyspnoea is a common symptom of respiratory disease. However, data on its prevalence in general populations and its association with lung function are limited and are mainly from high-income countries. The aims of this study were to estimate the prevalence of dyspnoea across several world regions, and to investigate the association of dyspnoea with lung function.

METHODS

Dyspnoea was assessed, and lung function measured in 25,806 adult participants of the multinational Burden of Obstructive Lung Disease study. Dyspnoea was defined as ≥2 on the modified Medical Research Council (mMRC) dyspnoea scale. The prevalence of dyspnoea was estimated for each of the study sites and compared across countries and world regions. Multivariable logistic regression was used to assess the association of dyspnoea with lung function in each site. Results were then pooled using random-effects meta-analysis.

RESULTS

The prevalence of dyspnoea varied widely across sites without a clear geographical pattern. The mean prevalence of dyspnoea was 13.7 % (SD=8.2 %), ranging from 0 % in Mysore (India) to 28.8 % in Nampicuan-Talugtug (Philippines). Dyspnoea was strongly associated with both spirometry restriction (FVC

CONCLUSION

The prevalence of dyspnoea varies substantially across the world and is strongly associated with lung function impairment. Using the mMRC scale in epidemiological research should be discussed.

The impact of urgency of umbilical hernia repair on adverse outcomes in patients with cirrhosis: a population-based cohort study from England

INTRODUCTION

Umbilical hernia is common in patients with cirrhosis; however, there is a paucity of dedicated studies on postoperative outcomes in this group of patients. This population-based cohort study aimed to determine the outcomes after emergency and elective umbilical hernia repair in patients with cirrhosis.

METHODS

Two linked electronic healthcare databases from England were used to identify all patients undergoing umbilical hernia repair between January 2000 and December 2017. Patients were grouped into those with and without cirrhosis and stratified by severity into compensated and decompensated cirrhosis. Length of stay, readmission, 90-day case fatality rate and the odds ratio of 90-day postoperative mortality were defined using logistic regression.

RESULTS

In total, 22,163 patients who underwent an umbilical hernia repair were included and 297 (1.34%) had cirrhosis. More patients without cirrhosis had an elective procedure, 86% compared with 51% of those with cirrhosis (P < 0.001). In both the elective and emergency settings, patients with cirrhosis had longer hospital length of stay (elective: 0 vs 1 day, emergency: 2 vs 4 days, P < 0.0001) and higher readmission rates (elective: 4.87% vs 11.33%, emergency:11.39% vs 29.25%, P < 0.0001) than those without cirrhosis. The 90-day case fatality rates were 2% and 0.16% in the elective setting, and 19% and 2.96% in the emergency setting in patients with and without cirrhosis respectively.

CONCLUSION

Emergency umbilical hernia repair in patients with cirrhosis is associated with poorer outcomes in terms of length of stay, readmissions and mortality at 90 days.

Pre-operative arthritic glenoid assessment: 3D automated planning software versus manual multiplanar measurements of version and inclination

Background

Preoperative CT-based planning is established in shoulder arthroplasty surgery. Automated planning software has become available to assist the surgeon and may increase reliability and efficiency. This study aims to evaluate the reliability of an automated 3-dimensional (3D) planning software package (Blueprint™ v2.1.5, Wright Medical Ltd) in the assessment of the arthritic shoulder against manual multiplanar measurement (MM).

Methods

74 CT studies acquired for preoperative shoulder arthroplasty planning were reviewed on two occasions by four different evaluators, taking manual measurement (MM) of glenoid version and inclination adjusted with multiplanar reformation and adhering to modified Freidman and Maurier methods. 15 scans were not processed by Blueprint due to incompatible scanning protocols or severe scapular dysmorphia. 59 Blueprint measures were compared with the manual data.

Results

Version: Intra-observer reliability of glenoid version MM was excellent (mean ICC 0.92). Inter-observer reliability between all four readers was good (ICC 0.89). A Bland-Altman analysis of Blueprint versus MM for version measurements demonstrated a mean pair difference of -5.77 (95% CI -7.25 to 4.29). Inclination: Intra-rater and inter-rater reliabilities were good (ICC 0.85 and 0.80 respectively). Blueprint and MM values for inclination followed a more convergent pattern than for version. Bland-Altman analysis for inclination did not show substantial bias, with a mean pair difference of 1.4 (95% CI -0.1 to 2.9).

Conclusion

Manual preoperative planning for shoulder arthroplasty is time consuming and requires experience. Automated 3D planning offers a consistent tool to assist the surgeon, notwithstanding intra-operative anatomical and technical variation, and margin of error. Surgeons should as ever be mindful of the specifics of a given automated program and our data quantified a bias for retroversion which may be important for measures close to the thresholds for augmentation or customised implants.

Concomitant coracoid base fracture and acromioclavicular joint disruption: A series of patients treated with a clavicle hook plate and review of the literature

INTRODUCTION

Concomitant acromioclavicular joint (ACJ) disruptions with coracoid base fractures are rare high energy injuries. The management of these injuries can be challenging. The aim of this study is to assess the functional and radiographic outcomes of a retrospective case series of patients presenting with concomitant ACJ and coracoid base injuries managed with a clavicle hook plate with subsequent hardware removal at a later stage.

METHODS

Six patients were identified for inclusion in the study. Radiographic and clinical data were available which allowed for collection of demographic information as well as classification of the fractures. Telephone consultation with patients allowed for collection of functional scores which included the Oxford shoulder score (OSS), QuickDASH (Q-DASH), Euroqol-5 Dimension (EQ-5D) and the SF-12 score.

RESULTS

All patients were male with a mean age of 39.8 years and a median follow-up period of 34 months. All patients underwent a successful operative procedure with a median time to union of 3.75 months. Good functional outcomes were reported by all patients: mean OSS 45.0, mean Q-DASH 4.8, mean EQ-VAS 82.8 and encouraging SF-12 scores (mean PCS 56.0, mean MCS 56.4).

CONCLUSION

The use of a lateral clavicle hook plate can achieve good healing and functional outcomes when managing patients with acromioclavicular joint disruptions associated with a coracoid base fracture.

The use of platelet-rich plasma therapy in treating tennis elbow: A critical review of randomised control trials

Tennis elbow (TE) is a painful and debilitating condition of the elbow. Recently, the use of orthobiologics, such as platelet-rich-plasma (PRP), has been proposed to promote tendon regeneration. Despite their popularity, there is a paucity of updated reviews on the use of PRP compared with other treatment modalities for treating TE. The aim of this review is to summarise high quality studies that compare the use of PRP therapy with other therapies for TE and to identify areas where further research is warranted. This systematic review was performed in accordance to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. A comprehensive literature search of PubMed, Scopus and Cochrane Library databases was undertaken in May 2021. Articles were screened for the following criteria: randomised control trials (RCTs) involving PRP in at least one of the treatment arms for tennis elbow. The quality of the RCTs included were analysed for their risk of bias using the modified Cochrane Collaboration Risk of Bias Assessment Tool for randomised trials. A total of 20 RCTs of which 1520 TE patients were analysed. The RCTs included in this review compared PRP with various treatment modalities routinely used in clinical practice such as physiotherapy, steroid injections, Autologous Whole Blood (AWB) and surgical interventions. With regards to the quality of RCTs, collectively, selection bias was found to be low risk however, performance bias in terms of blinding of participants and personnel performed poorly. Of the 20 RCTs, only 5 studies were classified as low risk of bias. In these 5 studies, 2 RCTs compared PRP with steroids and reported contrasting results, 1 RCT compared PRP with AWB injections which reported both to be similarly efficacious, 3 RCTs included a placebo group and only 1 reported superior effects with PRP. There are 2 main types of PRP classified according to the number of pro-inflammatory leukocyte i.e. leukocyte-rich and leukocyte-poor PRP. However, only 8 studies documented the formulation of PRP used. While the heterogeneity of PRP formulations could in-part explain the reported differences in outcomes, overall there is limited robust evidence to recommend PRP therapy for TE. Further research is required to establish the optimal formulation and administration of PRP injections. Proper documentation of TE patients need to be standardised before concrete recommendations on the use of PRP therapy may be offered.

O042 Risk of postoperative venous thromboembolism following benign colorectal surgery: systematic review and meta-analysis

Introduction

Venous thromboembolism (VTE) is a well-established complication after colectomy. VTE prophylaxis guidelines for benign colorectal disease is scarce, partly due to the paucity of studies reporting post-operative VTE rates of benign disease. This meta-analysis aimed to quantify the VTE risk after benign colorectal resection and determine its variability.

Methods

Embase, Medline, and 4 other registered medical databases were searched from database inception to 21 June 2021. Inclusion criteria: RCTs and large population-based database cohort studies reporting 30-day and 90-day VTE rates after benign colorectal resection in patients aged ≥18 years. Exclusion criteria: Patients undergoing colorectal cancer surgery. Studies were grouped for meta-analysis according to post-operative follow-up duration, admission type and indication for surgery.

Results

17 studies were eligible for meta-analysis reporting on 250,170 patients. Pooled 30-day and 90-day VTE incidence rates after benign colorectal resection were 284 (95%CI, 224–360) and 84 (95%CI, 33–218) per 1,000 person-years. Stratified by admission type, 30-day VTE incidence rates per 1,000 person-years were 532 (95% CI, 447–664) for emergency and 213 (95% CI, 100–453) for elective colorectal resections. 30-day VTE incidence rates per 1,000 person-years postcolectomy were 485 (95%CI, 411–573) for ulcerative colitis, 228 (95%CI, 181–288) for Crohn's disease and 208 (95%CI, 152–288) for diverticulitis patients.

Conclusion

VTE rates remain high up to 90-days after colectomy. Emergency compared to elective benign resections have higher rates of post-operative VTE. Further studies reporting VTE rates by type of benign disease need to stratify rates by admission type to more accurately define postcolectomy VTE risk.

Take-home message

VTE risk following benign colorectal surgery is high, especially among those who underwent emergency surgery. Extended venous thromboprophylaxis should be considered for these group of patients.

Study of Human Brucellosis among Patients with Pyrexia of Unknown Origin by Antibody Detection

This study was performed to determine the seropositivity of human brucellosis among the patients suffering from pyrexia of unidentified origin. This cross-sectional study was performed at department of Microbiology, Mymensingh Medical College, Mymensingh, Bangladesh from September 2018 to August 2019; among the patients of pyrexia of unknown origin visited inpatient and outpatient facility of department of Medicine and department of Paediatrics, Mymensingh Medical College Hospital (MMCH) in Mymensingh division of Bangladesh. A total of 400 serum samples were screened by Brucella-specific latex agglutination test to determine seropositivity. Seven percent (7.0%) (28/400) serum samples were found to be seropositive for brucellosis by detecting Brucella-specific antibody at a titer ≥1:160. Therefore, Brucella-specific latex agglutination test may be recommended as a screening test for human brucellosis in developing and underdeveloped countries.

Snapshot of a Child and Adolescent Psychiatric ER during Pandemic

Introduction

The COVID-19 pandemic has disrupted numerous fundamental systems ranging from businesses to education system. The long-term consequences of the Pandemic, namely virtual learning and prolonged social isolation are coming to fruition in Child/Adolescent-Psychiatric Emergency-Rooms (CAP-ER). Discontinuity of in-person attendance of schools has poorly impacted the mental health of children and adolescents (C&A) of low-socioeconomic areas, who often rely on schools for meals, physical activity, and mental-health support. An increase in agitation, suicidal ideation, and a declining school performance has been observed in such situations.

Objectives

The primary objective of this study is to explore the increase in these symptoms as the presenting complaint in the psychiatric ER.

Methods

Between April to June 2021 a cross-sectional quality improvement (QI) study was done on children presenting to CAP-ER BronxCare-Hospital NY with psychiatric complaints. Concomitant substance use disorder was determined using CRAFT questionnaire.

Results

Our data comprised 209 patients (84 M/125 F) with 79 children and 130 adolescents. Ethnicity: 116 Hispanics (56%), 84 African Americans (40%), and 9 others. The most common presenting complaints were aggression (111, 53%), suicidal ideation/suicide attempt (50, 24%), acute exacerbation of chronic illness (7, 3.3%), accidental overdosage (5, 2.3%) and others (36, 17.4). Marijuana was the most used substance (34 patients).

Conclusions

There has been a surge in severity of presentation of psychiatric disorders among children and adolescents, aggression so far, the most prevalent. Further studies are needed to delineate the social links with this high emergent load and pandemic.

“I rather talk on the phone”: Factors affecting compliance with outpatient visits during COVID-19 Pandemic

Introduction

The COVID-19 pandemic presented a global public-health crisis that demanded healthcare to adapt at an unprecedented pace. While challenging, it also created opportunities for the advancement of novel electronic-treatment-modalities. Telepsychiatry has emerged as an effective method to ensure continuity of care and ensure social distancing.1 Studies indicate that mental-health patients have higher rates of noncompliance to follow-up, 1 thus finding means to increase compliance is critical.

Objectives

The objectives of this study are to determine the impact of telepsychiatry on compliance to follow-up and to identify numbers of psychiatric/medical emergency-room visits, most common contributing factors for admission, and compliance in terms of diagnosis.

Methods

This IRB approved study is a retrospective chart-review, that aims to study children/adolescents (5-18 years) who presented to the Child&Adolescent-Psychiatry Outpatient-clinic from July-December 2020 and engaged in telepsychiatry, compared to a group of patients presented in July-December 2019-Pre-Covid19-Pandemic. A review of clinical characteristics including diagnosis, demographic information, medication, and treatment compliance will be compared as well as admissions to inpatient-psychiatry/emergency-room visits.

Results

Our total sample (N=252) included patients from 2019-Pre-COVID19 (N=111) and 2020 Telehealth during COVID19-Pandemic (N=141). Our data analysis using SPSF and T-test has shown that Telehealth has significantly increased follow-up compliance (Two-tailed P-value=0.04); 2019-Pre-COVID outreach mean=0.06, 2020-Telehealth-during COVID outreach mean=0.02); significantly decreased ER/CPEP visits (P-value=0.02), and decreased In-patient-unit admissions (P-value=0.02).

Conclusions

According to the presented study, the incorporation of telepsychiatry has increased the compliance to psychiatric-care in outpatient and decreased the emergency-room visits and inpatient admission. Sufficient resources and steps need to be taken to further strengthen telehealth services.

A comparative life cycle assessment of stretchable and rigid electronics: a case study of cardiac monitoring devices

Stretchable electronics is a new innovation and becoming popular in various fields, especially in the healthcare sector. Since stretchable electronics use less printed circuit boards (PCBs), it is expected that the environmental performance of a stretchable electronics-based device is better than a rigid electronics-based device that provides the same functionalities. Yet, such a study is rarely available. Thus, the main purpose of this research is to perform a comparative life cycle analysis of stretchable and rigid electronics-based devices. This research combines both the case study approach and the research review approach. For the case study, a cardiac monitoring device with both stretchable and rigid electronics is used. The ISO 14044:2006 standard's prescribed LCA approach and ReCiPe 2016 Midpoint (Hierarchist) are followed for the impact assessment using the SimaPro 9.1 software. The LCA results show that the stretchable cardiac monitoring device has better environmental performance in all eighteen impact categories. This research also shows that the manufacturing process of stretchable electronics has lower environmental impacts than those for rigid electronics. The main reasons for the improved environmental performance of stretchable electronics are lower consumption of raw material as well as decreased energy consumption during manufacturing. Based on the LCA results of a cardiac monitoring device, the study concludes that stretchable electronics and their manufacturing process have better environmental performance in comparison with the rigid electronics and their manufacturing process.

198 Immediate Post-Operative PDE5i Therapy Improves Early Erectile Function Outcomes after Robot-Assisted Radical Prostatectomy (RARP)

Aim

To assess whether the timing of post-operative Phosphodiesterase Inhibitor (PDE5i) therapy after Robot Assisted Radical Prostatectomy (RARP) is associated with a change in early erectile function, continence, or safety outcomes.

Method

Data was prospectively collected from a single surgeon in one tertiary centre and retrospectively evaluated. 158 patients were treated with PDE5i therapy post RARP over a two-year period.

Results

There were no significant differences in pre-operative characteristics between the therapy groups. Patients that had bilateral nerve sparing had a mean drop in Erectile Function (EF) score by 5.4 compared to 8.8 in the unilateral group. Additionally, 34.9% of bilateral nerve sparing patients returned to baseline compared to 12.1% of unilateral. Drop in EF scores and percentage return to baseline for unilateral nerve sparing was respectively 9 and 11.1% of immediate (day 1-2), 7 and 14.8% of early (day 3-14) and 9.7 and 9.5% of late (day &gt;14) therapy (p = 0.9 and p = 0.6). For bilateral nerve sparing this was respectively 3.5 and 42.9% immediate therapy, 5.5 and 35.5% early therapy and 7.3 and 25% late therapy (p = 0.017 and p = 0.045). Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early therapy and 26% and 54% for late therapy. There were no differences in compliance, complication, or readmission outcomes.

Conclusions

Immediate PDE5i therapy should be considered in patients following nerve sparing RARP in order to maximise functional outcomes, especially in those undergoing bilateral nerve spare.

141 New Guidelines to Reduce Unnecessary Blood Tests, Delayed Discharge and Costs Following Robot Assisted Radical Prostatectomy

Objectives

Routine postoperative blood tests (POBT) following robot assisted radical prostatectomy (RARP) are used to evaluate the impact of surgery on pre-existing co-morbidities and to detect early complications. This practice dates back to an era of open surgery, when blood loss and complication rates were higher. We propose new guidelines to improve the specificity of POBT.

Method

The cases of 1040 consecutive patients who underwent a primary or salvage RARP at two large tertiary urology centres in the United Kingdom were retrospectively reviewed to form new guidelines. The new guidelines were prospectively validated in a sample of 300 patients.

Results

Derivation Dataset: 3% and 5% had intra- and post-operative Clavien-Dindo complications, respectively. 15% had clinical concerns postoperatively. 0.9% required perioperative transfusion. 78% had routine blood tests without clinical concerns, none of whom developed a complication. 98% of complications were suspected by clinical judgement. 6% of patients had a discharge delay of ≥ 1 day due to delayed or incomplete blood tests. Validation Dataset: No significant difference existed in complication, clinical concern or transfusion rates between the derivation and validation datasets. Number of POBT requested reduced by 73% (p &lt; 0.001). The new guidelines improved POBT sensitivity for complications from 98% to 100% and specificity from 0% to 74%. Discharge delays reduced from 6% to 0% (p = 0.008). Cost savings were £178 per patient.

Conclusions

Postoperative complications and transfusion following RARP are rare. Routine POBT without clinical indication are unnecessary and inefficient. A guideline-based approach to POBT can reduce costs and optimise discharge without compromising patient safety or care.

Take-home Message

Routine postoperative blood tests following robot assisted radical prostatectomy are often unnecessary. A guideline-based approach can reduce costs and optimise patient care.

236 Novel Guidelines to Avoid Routine Blood Tests After Robotic Assisted Radical Prostatectomy (RARP)

Introduction

Patients undergoing RARP commonly require routine post-operative blood tests. This practice dates from an era of open surgery, with increased blood loss and complications. We aim to improve specificity of blood test requests with novel guidelines.

Method

1039 consecutive RARP patients at two tertiary urology centres in the UK were audited. Novel guidelines constructed based on risk stratified evidence from the initial audit were used to prospectively audit 133 patients.

Results

16% had clinical concerns post-operatively. 1% and 4% had an intra- and post-operative complication. Intra- or post-operative clinical judgement flagged post-operative complications in 99.9%. 80% had routine blood tests with no clinical concerns. 6% had delayed discharge due to delayed processing of blood tests. 0.9% received a peri-operative transfusion.

Re-Audit Novel guidelines reduced the number of blood tests requested from 100% to 36%. Specificity in diagnosing a complication improved from 0% to 67%. Discharge delays reduced from 6% to 0% and no post-operative complications were missed (sensitivity 100%).

Conclusions

Routine blood tests, without an indication, did not flag any additional post-operative complications. Blood transfusion is rare for RARP. Novel guidelines to request post-operative blood tests will reduce costs and discharge delays whilst maintaining appropriate patient safety and care.

31 Immediate Post-Operative Phosphodiesterase-5 Inhibitors (PDE5i) Therapy Improves Early Erectile Function Outcomes After Robot Assisted Radical Prostatectomy (RARP)

Introduction

To assess whether the timing of post-RARP PDE5i therapy affects early erectile function, continence, or safety outcomes.

Method

Data from 158 patients treated with PDE5is post-RARP was prospectively collected over two years from a single surgeon at one tertiary centre and retrospectively evaluated. Therapy was started: immediately (day 1-2) in 29%, early (day 3-14) in 37% and late (after day 14) post-op in 34%. EPIC-26 Erectile Function (EF) scores were collected pre-op and post-op after a median 43-day follow-up interval.

Results

Drop in EF scores and percentage return to baseline post unilateral nerve sparing (UNS) compared to bilateral nerve sparing (BNS) RARP was respectively 9 and 11.1% versus 3.5 and 42.9% of immediate therapy, 7 and 14.8% versus 5.5 and 35.5% of early and 9.7 and 9.5% versus 7.3 and 25% of late. Pad free and social continence was achieved in 54% and 37% of those receiving immediate therapy, 60% and 33% for early and 26% and 54% for late.

Conclusions

Immediate post RARP PDE5i therapy may protect EF and should be considered clinically, with more benefits for BNS than UNS patients. Immediate or early, rather than late, PDE5i therapy improved early continence in BNS patients.

610 Virtual Burns Care in The Era Of COVID-19: A Regional Burns Unit’s Experience

Introduction

In response to the COVID-19 pandemic a virtual burns service was established in Northern Ireland to reduce face-to-face consultations to only complex burns or those necessitating hospital admission to the regional unit.

Method

A combination of telephone calls, emails, photography, and Microsoft Teams software was utilised to facilitate a virtual review service. Our initial adoption of the system was audited during April and May 2020. Through Plan-Do-Study-Act (PDSA) methodology an electronic tertiary-referral proforma was established prior to closure of the audit cycle in July 2020.

Results

From the start of lockdown a significant reduction in face-to-face consultations was observed. Given the increasing use of virtual telephone consultation only 19.5% of the unit's total referrals (April, May, and July) were either reviewed face-to-face in dressing clinic or admitted. A target of 100% data point entry (including demographic, clinical, and initial management) for patients entering the virtual service was set. Following implementation of the e-Referral pathway an improvement in both the detail and completeness (95%) of patient referral information was achieved.

Conclusions

Our experience demonstrates that virtual burns care can be safely and rapidly adapted in response to evolving need. The potential role of virtual care post-COVID, in selected patients, is an exciting one.

Clinical and Radiological Study of Serum Fluoride in Relation to Knee Osteoarthritis

Introduction

Fluorosis has been associated with an increased risk of degenerative changes in the knee. Multiple studies have found an association between arthritis and elevated fluoride levels. We aim to delineate if elevated fluoride level has any direct correlation with the degree of radiological grading and clinical symptoms in knee arthritis.

Materials and Methods

A cross-sectional study of 80 knee arthritis patients was conducted from February 2017 to April 2018. Serum fluoride levels were measured and patient's pain scores, WOMAC scores and radiological grading were correlated with the elevated fluoride levels.

Results

In our study, 30 out of 80 patients had increased serum fluoride level. Statistically significant differences were noted in VAS score, WOMAC score and Kellgren and Lawrence radiological grades between patients with normal serum fluoride level and those with elevated fluoride level.

Conclusion

There is an increased risk of knee arthritis in patients with elevated blood fluoride levels and patients with increased fluoride levels are associated with more severe symptoms and radiographic disease.

Shoulder arthroplasty for juvenile idiopathic arthritis

There is limited literature to guide shoulder surgeons in the management of juvenile idiopathic arthritis (JIA). We aim to help clinicians to formulate an approach to the surgical management of the condition through a review of the available literature on arthroplasty in JIA, general considerations when operating on patients with inflammatory arthropathy and recommendations based on the authors' experience. Four articles report formal data on arthroplasty in JIA with favourable improvements in post-operative pain and function scores after the long-term follow-up. Significant heterogeneity in treatment and a lack of standardisation in quantitative outcomes highlights the need for further larger scale and higher quality research. The aim of this study is to review the evidence and provide information on preoperative evaluation of surgical candidates, operative techniques, choice of implant design and to evaluate functional outcomes in patients who undergo shoulder arthroplasty.

Arthroscopically-assisted fixation of anteromedial coronoid facet fracture and lateral ulnar collateral ligament repair for acute posteromedial rotatory fracture dislocation of the elbow

If left untreated, varus posteromedial rotatory injuries of the elbow result in poor functional outcomes. Surgical treatment allows restoration of elbow kinematics, minimizing the chances of chronic varus instability and early onset osteoarthritis. However, large exposures are associated with extensive soft tissue stripping, a high risk of infection, nerve injury, poor visualization of the articular surface and longer recovery. Consequently, there has been renewed interest in the use of elbow arthroscopy to circumvent these problems. Arthroscopic treatment offers the potential advantage of a swift recovery, with instant rehabilitation, less stiffness and swelling than might be expected after open repair. We present the first combined arthroscopic-assisted anteromedial facet coronoid fracture fixation and lateral ulna collateral ligament repair in a varus posteromedial rotatory injury of the elbow.

Knowledge, attitude and practice towards dietary iron among patients with thalassemia and their caregivers in Peninsular Malaysia

INTRODUCTION

Thalassemias are the most common human monogenic disorders in the world. Regular blood transfusion and increased intestinal absorption of iron among thalassemia patients will lead to iron overload, which will not only markedly decrease their life expectancy but also pose a heavy burden to the healthcare system. The objective of this study was to evaluate the level of knowledge, attitude and practice towards dietary iron among thalassemia patients and their caregivers.

METHODS

An analytical cross-sectional study using purposive sampling method was conducted at eight thalassemia societies in Peninsular Malaysia. 260 respondents comprised of patients and caregivers were assessed with two separate sets of questionnaires.

RESULTS

Knowledge on dietary iron among the respondents was unsatisfactory, despite them having good knowledge on thalassemia disorder. Female patients were found to have better dietary knowledge, attitude and practice compared to males. The percentage of caregivers with good attitude and good practice were significantly higher compared to adult patients. Caregivers with children on iron chelators were noted to have better dietary attitude and practice. Thalassemia knowledge and children on vitamins were found to be the predictors of dietary knowledge among the patients and caregivers respectively.

CONCLUSION

The level of knowledge on dietary iron among the patients and caregivers was unsatisfactory in spite of their attitude and practice towards dietary iron were good. Effective delivery of dietary information to the patients and caregivers is essential to enable them to choose a healthy diet for their condition.

The Rockwood classification in acute acromioclavicular joint injury does not correlate with symptoms

PURPOSE

Rockwood classified acromioclavicular (AC) joint injuries by displacement of the joint on radiographs. This classification has driven the management dogma of acute AC dislocation. The correlation between Rockwood grade and symptoms has not been described in acute injury. This study assesses that relationship.

METHODS

This series included 77 patients with acute AC joint injury (<6 weeks), treated between 2006 and 2015. Objective and patient-reported measures enabled correlation between clinical measures and Rockwood grade.

RESULTS

The mean age was 32 years (±11.86; range 17-59 years); 88% were male. Forty-four per cent were professional athletes and 43% suffered injury during rugby. The mean time from injury to presentation was 2 weeks (±1.64; range 0-5 weeks). There was poor correlation between Rockwood classification and pain (visual analogue scale) ( r_s = 0.05; p = 0.752). Poor correlation was noted between Rockwood grade and functional deficit (elevation ( r_s = 0.18; p = 0.275), abduction ( r_s = 0.19; p = 0.246) and strength ( r_s = 0.09; p = 0.579) vs. contralateral side). Oxford and Constant scores did not correlate with Rockwood grade ( r_s = 0.13; p = 0.972 and 0.01; p = 0.448, respectively).

CONCLUSION

The Rockwood grade does not correlate with clinical symptoms in acute AC joint injury. Previous evidence demonstrates the Rockwood classification's limitations in predicting the structures injured. Therefore, the reliability of using the Rockwood grade as a decision-making tool in the management of acute AC joint dislocation is unclear.

Simultaneous Biofortification of Wheat with Zinc, Iodine, Selenium, and Iron through Foliar Treatment of a Micronutrient Cocktail in Six Countries

Field experiments were conducted on wheat to study the effects of foliar-applied iodine(I) alone, Zn (zinc) alone, and a micronutrient cocktail solution containing I, Zn, Se (selenium), and Fe (iron) on grain yield and grain concentrations of micronutrients. Plants were grown over 2 years in China, India, Mexico, Pakistan, South Africa, and Turkey. Grain-Zn was increased from 28.6 mg kg^-1 to 46.0 mg^-1 kg with Zn-spray and 47.1 mg^-1 kg with micronutrient cocktail spray. Foliar-applied I and micronutrient cocktail increased grain I from 24 μg kg^-1 to 361 μg kg^-1 and 249 μg kg^-1, respectively. Micronutrient cocktail also increased grain-Se from 90 μg kg^-1 to 338 μg kg^-1 in all countries. Average increase in grain-Fe by micronutrient cocktail solution was about 12%. The results obtained demonstrated that foliar application of a cocktail micronutrient solution represents an effective strategy to biofortify wheat simultaneously with Zn, I, Se and partly with Fe without yield trade-off in wheat.

Eight-year follow-up of resurfacing hemiarthroplasty for advanced glenohumeral osteoarthritis following total acromionectomy

Total acromionectomy is now a largely historical procedure due to a number of biomechanical sequelae caused by defunctioning of the deltoid, although its overall effect on joint kinematics is uncertain. This presents a challenge when considering arthroplasty for subsequent glenohumeral arthritis. We report on successful management of such a case, treated with resurfacing hemiarthroplasty 57 years following acromionectomy. The patient continues to enjoy excellent functional outcome of the shoulder at 8 years after arthroplasty.

Resurfacing hemiarthroplasty of the shoulder for patients with juvenile idiopathic arthritis

BACKGROUND

This study reports the outcome of resurfacing hemiarthroplasty (RHA) in a cohort of patients with juvenile idiopathic arthritis (JIA) affecting the shoulder joint METHODS: Fourteen uncemented RHA procedures were performed for 11 consecutive patients who required surgery because of JIA. Mean age at surgery was 36.4 years. Mean clinical follow-up was 10.4 years (range, 5.8-13.9 years). A significant humeral head defect (up to 40% surface area) was found in 5 shoulders and filled with autograft from the distal clavicle or femoral head allograft.

RESULTS

At latest follow-up, no patient required revision. There was excellent relief from pain. The mean Oxford Shoulder Score and Constant-Murley Score improved significantly. No shoulder had a poor outcome, and 6 had a very good or excellent outcome. Worse outcome was associated with an intraoperative finding of significant humeral head erosion. Two shoulders required early arthroscopic subacromial decompression, but there were no other reoperations. There were no instances of radiographic implant loosening or proximal migration. Painless glenoid erosion was seen in 5 shoulders but was not associated with worse outcome.

CONCLUSIONS

The midterm results of RHA for JIA are at least comparable to those for stemmed hemiarthroplasty, with the added benefit of bone conservation.

The prevalence and the risk of falls among institutionalised elderly in Penang, Malaysia

INTRODUCTION AND OBJECTIVES

Over the years, falls has been increasingly the most common public health issue worldwide that affects all age groups. However, the risk is nine times higher in older persons especially among those residing in nursing homes. The objective of this study is to determine the prevalence and the risk of falls and their associated factors among elderly living in nursing homes in Penang, Malaysia.

METHODOLOGY

Data were obtained from a cross-sectional survey in ten different nursing homes in the state of Penang, Malaysia. Participants were selected through convenience sampling were interviewed face-to-face using a questionnaire. Information concerning demographic characteristics, fall risk and depression status were collected.

RESULTS

Of the 357-elderly aged 60 years and above interviewed in the nursing homes, 32.8% (n=354) reported having one or more falls in the past 12 months whereas 13.3% were at moderate/high risk of fall. Depression (Adjusted Odds Ratio (aOR)=1.71, 95%CI: 1.00 to 2.91) and respiratory illnesses (aOR=3.38, 95%CI: 1.11 to 10.30) were shown to be associated with prevalence of falls. Depression (aOR=2.12, 95%CI: 1.06 to 4.23) and history of fall more than once in the past 12 months (aOR=3.90, 95%CI: 1.72 to 8.8) were found to be associated with moderate/high risk of falls.

CONCLUSION

This study showed that the prevalence of fall was higher among depressed elderly and those with respiratory illness. Elderly with higher history of falls were also at higher risk of falls. These findings suggest the importance of screening the elderly for the risk factors of falls as a preventive measure.

Prähospitale Telemedizin beim neurologischen Notfall

Gegenstand und Zie: Es wird eine Übersicht über die laufenden Projekte in der prähospitalen neurologischen Notfallversorgung gegeben. Material und Methoden: An Beispielen telemedizinischer Projekte in der Notfallversorgung, mit Schwerpunkt in der Akutversorgung des Schlaganfalls, werden die unterschiedlichen Ansätze und Möglichkeiten aufgezeigt und erste Ergebnisse referiert. Ergebnisse: Prähospitale telemedizinische Projekte unterstützen die Akutversorgung neurologischer Notfälle und wirken als Katalysator für die Vernetzung medizinischer Versorgungseinrichtungen in der Region und für die Kommunikation zwischen Notärzten/Rettungsdienst präklinisch und den Klinikteams. Durch die EDV-basierte Datenerhebung ist eine kontinuierliche Prozessoptimierung möglich, sodass z. B. beim Schlaganfall innerklinische Prozesse beschleunigt und die Lyserate unter einer konstanten Mortalitätsrate erhöht werden konnte. Schlussfolgerungen: Telemedizin ist bei der prähospitalen Schlaganfallversorgung anwendbar und führt durch die EDV-basierte Datensammlung zu mehr Transparenz der Prozesse, wodurch innerklinische Abläufe um die Stroke-Unit-Konzeption optimiert werden können.

Arthroscopic Sternoclavicular Joint Diskectomy for Acute and Chronic Tears

PURPOSE

To describe the results and functional scores in a group of patients who underwent arthroscopic excision of a symptomatic sternoclavicular joint (SCJ) disk tear with a minimum follow-up period of 2 years.

METHODS

Between April 2010 and December 2014, 14 patients underwent arthroscopic excision of a torn SCJ disk. Patients whose intended surgery was an isolated diskectomy and underwent that surgery only, with no additional procedure, were included. The minimum follow-up period was 24 months. All patients underwent an arthroscopic SCJ diskectomy. Postoperatively, no immobilization was required, and the patients were encouraged to mobilize as pain permitted. The patients were assessed preoperatively and at final follow-up with the visual analog scale score for pain, Rockwood score, and QuickDASH (short version of the Disabilities of the Arm, Shoulder and Hand questionnaire) score.

RESULTS

The average age at surgery was 29.4 years (range, 19-39 years). Ten of the patients had been symptom free before a specific incident, after which SCJ symptoms developed. The other 4 patients reported a gradual onset of symptoms and were considered to have chronic tears. The average duration of symptoms was 22.8 months (range, 6-48 months). At a mean follow-up of 33.4 months (range, 24-59 months), a significant improvement in the Rockwood score was noted, from 7 (range, 5-9; standard deviation [SD], 1.4) to 13.6 (range, 9-15; SD, 1.9) (P = .001) (minimal clinically important difference not described). The mean QuickDASH score improved from 23.7 points (range, 6.8-40.9 points; SD, 11.8 points) to 8 points (range, 0-29.5 points; SD, 9 points) (P = .0024) (minimal clinically important difference, 13.4 points). There were no reported complications and specifically no instability.

CONCLUSIONS

The results of this series suggest that arthroscopic SCJ diskectomy is a safe and reproducible procedure for the treatment of patients with symptomatic SCJ disk tears.
