Abstract
Background A minority of patients presenting to hospital with COVID-19 have bacterial coinfection. Procalcitonin testing may help identify patients for whom antibiotics should be prescribed or withheld. The PEACH study describes the use of procalcitonin in English and Welsh hospitals during the first wave of the COVID-19 pandemic to help diagnose bacterial infections and guide antibiotic treatment. There is a lack of clear evidence to support its use in lung infections, which means in some hospitals, clinicians have used the procalcitonin test to guide antibiotic decisions in COVID-19, whilst in other hospitals, they have not. Our study is analysing data from hospitals that did and did not use procalcitonin testing during the first wave of the COVID-19 pandemic. It will determine whether and how procalcitonin testing should be used in the NHS in future waves of COVID-19 to protect patients from antibiotic overuse. Methods To assess whether the use of PCT testing, to guide antibiotic prescribing, safely reduced antibiotic use among patients who were hospitalized with COVID-19 during the first wave of the pandemic, we are answering this question through three different, and complimentary, work streams (WS), each with discrete work packages (WP): (i) Work Stream 1: utilization of PCT testing to guide antibiotic prescribing during the first wave of COVID-19 pandemic; (ii) Work Stream 2: patient-level impact of PCT testing on antibiotic exposure and clinical outcome (main work stream currently in analysis); and (iii) Work Stream 3: health economics analysis of PCT testing to guide antibiotics in COVID-19. Results Our first publication from Work Stream 1 (Antibiotics 2021, 10: 516) used a web-based survey to gather data from antimicrobial leads about the use of procalcitonin testing. Responses were received from 148/151 (98%) eligible hospitals. During the first wave of the COVID-19 pandemic, there was widespread introduction and expansion of PCT use in NHS hospitals. The number of hospitals using PCT in emergency/acute admissions rose from 17 (11%) to 74/146 (50.7%) and use in ICU increased from 70 (47.6%) to 124/147 (84.4%). This increase happened predominantly in March and April 2020, preceding NICE guidance. Approximately half of hospitals used PCT as a single test to guide decisions to discontinue antibiotics and half used repeated measurements. There was marked variation in the thresholds used for empirical antibiotic cessation and guidance about interpretation of values. Conclusions Procalcitonin testing has been widely adopted in the NHS during the COVID-19 pandemic in an unevidenced, heterogeneous way and in conflict with relevant NICE guidance. Further research is needed urgently that assesses the impact of this change on antibiotic prescribing and patient safety. Work Stream 2 is ongoing, and results will be published once available.

Abstract
Hospital outbreaks of COVID19 result in considerable mortality and disruption to healthcare services and yet little is known about transmission within this setting. We characterise within hospital transmission by combining viral genomic and epidemiological data using Bayesian modelling amongst 2181 patients and healthcare workers from a large UK NHS Trust. Transmission events were compared between Wave 1 (1st March to 25th J'uly 2020) and Wave 2 (30th November 2020 to 24th January 2021). We show that staff-to-staff transmissions reduced from 31.6% to 12.9% of all infections. Patient-to-patient transmissions increased from 27.1% to 52.1%. 40%-50% of hospital-onset patient cases resulted in onward transmission compared to 4% of community-acquired cases. Control measures introduced during the pandemic likely reduced transmissions between healthcare workers but were insufficient to prevent increasing numbers of patient-to-patient transmissions. As hospital-acquired cases drive most onward transmission, earlier identification of nosocomial cases will be required to break hospital transmission chains.

Abstract
Background Chronic pain and insomnia have a complex, bidirectional relationship – addressing sleep complaints alongside pain may be key to alleviating patient-reported distress and disability. Healthcare professionals have consistently reported wanting to offer psychologically informed chronic pain management at the primary care level. Research in secondary care has demonstrated good treatment efficacy of hybrid CBT for chronic pain and insomnia. However, primary care is typically the main point of treatment entry, hence may be better situated to offer treatments using a multidisciplinary approach. In this study, primary care service providers’ perception of feasibility for tackling pain-related insomnia in primary care was explored. Methods The data corpus originates from a feasibility trial exploring hybrid CBT for chronic pain and insomnia delivered in primary care. This formed three in-depth group interviews with primary care staff (n = 9) from different primary care centres from the same NHS locale. All interviews were conducted on-site using a semi-structured approach. Verbal data was recorded, transcribed verbatim and analysed using the thematic analysis process. Results Eight themes were identified – 1) Discrepant conceptualisations of the chronic pain-insomnia relationship and clinical application, 2) Mismatch between patients’ needs and available treatment offerings, 3) Awareness of psychological complexities, 4) Identified treatment gap for pain-related insomnia, 5) Lack of funding and existing infrastructure for new service development, 6) General shortage of psychological services for complex health conditions, 7) Multidisciplinary team provision with pain specialist input, and 8) Accessibility through primary care. These mapped onto four domains - Current understanding and practice, Perceived facilitators, Perceived barriers, Ideal scenarios for a new treatment service – which reflected the focus of our investigation. Taken together these provide key context for understanding challenges faced by health care professionals in considering and developing a new clinical service. Conclusions Primary care service providers from one locale advocate better, multidisciplinary treatment provision for chronic pain and insomnia. Findings suggest that situating this in primary care could be a feasible option, but this requires systemic support and specialist input as well as definitive trials for success.

Abstract
Background Multisystem Inflammatory Syndrome in Adults (MIS-A) is a recently emerging condition that occurs as a delayed complication of COVID-19 infection. It involves inflammation of multiple extra-pulmonary organ systems. Diagnostic criteria and treatment recommendations have yet to be clearly defined. We present a case of a young adult with suspected MIS-A who initially displayed symptoms and radiological findings of colitis. Case: A 22-year-old male with no past medical history suffered a minor respiratory illness for a few days and tested positive on SARS-CoV-2 RT-PCR. Approximately 6 weeks later, he presents after 3 days of right-sided abdominal pain, diarrhoea and fever. He is initially admitted with a working diagnosis of gastroenteritis. Sustained fever and escalating blood markers of illness led to abdominal CT; showing inflammation of ascending colon as well as some loops of small bowel. Hypotension becomes increasingly pronounced and on the fourth day of admission he developed type 1 respiratory failure with evidence of fluid overload. He was transferred to critical care for vasopressor and respiratory support. All microbiological and autoimmune screens performed return negative results but inflammatory markers were significantly elevated, he was diagnosed as MIS-A. IVIg was added to the antibiotics on day 4. His clinical condition dramatically improved and he was discharged home after 10 days in hospital. His blood tests have returned to normal and he has no lasting complications from his illness. Discussion This case displays the potential for MIS-A to present in various ways, with this example a primarily gastroenterological illness. It therefore highlights the importance of physicians in different fields having an awareness of the condition, in order to identify when MDT input is required to guide treatment. We review the current literature on various presentations and treatments of MIS-A, and discuss the need for clear case definition.

Abstract
BACKGROUND Complicated intra-abdominal infections (cIAIs) are associated with significant morbidity and mortality. The aim of this study was to describe the clinical characteristics of patients with cIAI in a multicentre study and to develop clinical prediction models (CPMs) to help identify patients at risk of mortality or relapse. METHODS A multicentre observational study was conducted from August 2016 to February 2017 in the UK. Adult patients diagnosed with cIAI were included. Multivariable logistic regression was performed to develop CPMs for mortality and cIAI relapse. The c-statistic was used to test model discrimination. Model calibration was tested using calibration slopes and calibration in the large (CITL). The CPMs were then presented as point scoring systems and validated further. RESULTS Overall, 417 patients from 31 surgical centres were included in the analysis. At 90 days after diagnosis, 17.3 per cent had a cIAI relapse and the mortality rate was 11.3 per cent. Predictors in the mortality model were age, cIAI aetiology, presence of a perforated viscus and source control procedure. Predictors of cIAI relapse included the presence of collections, outcome of initial management, and duration of antibiotic treatment. The c-statistic adjusted for model optimism was 0.79 (95 per cent c.i. 0.75 to 0.87) and 0.74 (0.73 to 0.85) for mortality and cIAI relapse CPMs. Adjusted calibration slopes were 0.88 (95 per cent c.i. 0.76 to 0.90) for the mortality model and 0.91 (0.88 to 0.94) for the relapse model; CITL was -0.19 (95 per cent c.i. -0.39 to -0.12) and - 0.01 (- 0.17 to -0.03) respectively. CONCLUSION Relapse of infection and death after complicated intra-abdominal infections are common. Clinical prediction models were developed to identify patients at increased risk of relapse or death after treatment, these now require external validation.

Abstract
It can be a diagnostic challenge to identify patients with coronavirus disease 2019 in whom antibiotics can be safely withheld. This study evaluated the effectiveness of a guideline implemented at Sheffield Teaching Hospitals NHS Foundation Trust that recommends withholding antibiotics in patients with low serum procalcitonin (PCT), defined as ≤0.25 ng/mL. Results showed reduced antibiotic consumption in patients with PCT ≤0.25 ng/mL with no increase in mortality, alongside a reduction in subsequent carbapenem prescriptions during admission. The results support the effectiveness of this guideline, and further research is recommended to identify the optimal cut-off value for PCT in this setting.

Abstract
Background Patellar instability is a relatively common condition that leads to disability and restriction of activities. People with recurrent instability may be given the option of physiotherapy or surgery though this is largely driven by clinician preference rather than by a strong evidence base. We sought to determine the feasibility of conducting a definitive trial comparing physiotherapy with surgical treatment for people with recurrent patellar instability. Methods This was a pragmatic, open-label, two-arm feasibility randomised control trial (RCT) with an embedded interview component recruiting across three NHS sites comparing surgical treatment to a package of best conservative care; ‘Personalised Knee Therapy’ (PKT). The primary feasibility outcome was the recruitment rate per centre (expected rate 1 to 1.5 participants recruited each month). Secondary outcomes included the rate of follow-up (over 80% expected at 12 months) and a series of participant-reported outcomes taken at 3, 6 and 12 months following randomisation, including the Norwich Patellar Instability Score (NPIS), the Kujala Patellofemoral Disorder Score (KPDS), EuroQol-5D-5L, self-reported global assessment of change, satisfaction at each time point and resources use. Results We recruited 19 participants. Of these, 18 participants (95%) were followed-up at 12 months and 1 (5%) withdrew. One centre recruited at just over one case per month, one centre was unable to recruit, and one centre recruited at over one case per month after a change in participant screening approach. Ten participants were allocated into the PKT arm, with nine to the surgical arm. Mean Norwich Patellar Instability Score improved from 40.6 (standard deviation 22.1) to 28.2 (SD 25.4) from baseline to 12 months. Conclusion This feasibility trial identified a number of challenges and required a series of changes to ensure adequate recruitment and follow-up. These changes helped achieve a sufficient recruitment and follow-up rate. The revised trial design is feasible to be conducted as a definitive trial to answer this important clinical question for people with chronic patellar instability. Trial registration The trial was prospectively registered on the International Standard Randomised Controlled Trial Number registry on the 22/12/2016 (reference number: ISRCTN14950321). http://www.isrctn.com/ISRCTN14950321

Abstract
Abstract
Background: Inflammatory breast cancer (IBC) is an aggressive form of breast cancer that remains relatively understudied. We examined the efficacy of neoadjuvant dual-HER2 blockade (trastuzumab (H) and pertuzumab (P)) combined with paclitaxel (T) in HER2+ IBC, including a planned analysis to elucidate associations between the tumor immune microenvironment profile and response to therapy.
Methods: An IRB-approved, single-arm phase II trial for patients (pts) with newly diagnosed HER2+ IBC was conducted. Pts had a pre-treatment biopsy of the affected breast (D1) followed by a loading dose of HP. A second biopsy was performed 1 week (wk) later (D8), when T (80mg/m2/wk x 16 wks) was added to HP. Responding pts underwent modified radical mastectomy (MRM) where residual disease was collected. The primary objective was to determine the rate of pathologic complete response (pCR) defined as ypT0/isN0. Residual Cancer Burden (RCB) was also determined. Tumor specimens from D1, D8 and MRM were assessed for disease cellularity and scored for percentage of tumor infiltrating lymphocytes (TILs): low=0-10%, intermediate=11-59%, high>60%. RNA-sequencing was performed on tumor tissue from D1 and D8 to explore the impact of short-term HP treatment on the tumor transcriptomic profile and to identify potential predictors of pCR.
Results: 23 pts with HER2+ IBC were enrolled between 8/2013-6/2017. Mean age was 48 years (range 32-74); 11 pts (48%) had estrogen and progesterone receptor (ER/PR) negative disease. Matched tumor biopsies (D1, D8) were obtained in all 23 pts; 21 underwent MRM; 1 was lost to follow-up and 1 had disease progression. In the intent to treat analysis, 10/23 (43%) pts achieved a pCR and 7 (30%) had RCB-1. Ten of the 22 evaluable pts achieved a pCR (45.5%). TILs were evaluable in 20/23 (87%) matched tumor biopsies (D1, D8). Among the D1 biopsy specimens: 19 (95%) had low levels, 2 (10%) had intermediate levels, and none had high levels. When D1 TIL levels were compared with D8 levels, 3(15%) had an increase in TILs, 16(80%) had no change in TIL levels, and 1(5%) had a decrease in the level of TILs. Both samples with intermediate levels and 2 of 3 samples with high levels of TILs on D1 and D8 were seen in ER/PR negative disease. An evaluation of biopsy specimens associated with subsequent pCR using GO enrichment analysis from the RNA-Seq data showed significant upregulation of several immune-process related gene expression signatures both at D1 and D8 (e.g. antigen processing and presentation, TCR signaling, NK cell cytotoxicity, p-value: 2.99E-48 to 1.39E-16) when compared with those associated with residual disease at the time of MRM. Across the entire cohort, D8 biopsies showed evidence of upregulated anti-tumor immunity compared to D1 biopsies (p-value: 9.57E-06 to 0.012). Notably, this change from D1 to D8 was largely restricted to tumors that achieved a pCR.
Conclusion: THP for 16 weeks was a highly effective treatment for HER2+ IBC. Immune activation as determined by gene expression signatures predicted pCR, and moreover upregulation of anti-tumor immunity after 1 wk of HP might further predict a complete pathologic response to therapy.

Abstract
Aims Ceramic-on-ceramic (CoC) bearings in total hip arthroplasty (THA) are commonly used, but concerns exist regarding ceramic fracture. This study aims to report the risk of revision for fracture of modern CoC bearings and identify factors that might influence this risk, using data from the National Joint Registry (NJR) for England, Wales, Northern Ireland and the Isle of Man. Patients and Methods We analysed data on 223 362 bearings from 111 681 primary CoC THAs and 182 linked revisions for bearing fracture recorded in the NJR. We used implant codes to identify ceramic bearing composition and generated Kaplan-Meier estimates for implant survivorship. Logistic regression analyses were performed for implant size and patient specific variables to determine any associated risks for revision. Results A total of 222 852 bearings (99.8%) were CeramTec Biolox products. Revisions for fracture were linked to seven of 79 442 (0.009%) Biolox Delta heads, 38 of 31 982 (0.119%) Biolox Forte heads, 101 of 80 170 (0.126%) Biolox Delta liners and 35 of 31 258 (0.112%) Biolox Forte liners. Regression analysis of implant size revealed smaller heads had significantly higher odds of fracture (chi-squared 68.0, p < 0.001). The highest fracture risk was observed in the 28 mm Biolox Forte subgroup (0.382%). There were no fractures in the 40 mm head group for either ceramic type. Liner thickness was not predictive of fracture (p = 0.67). Body mass index (BMI) was independently associated with revision for both head fractures (odds ratio (OR) 1.09 per unit increase, p = 0.031) and liner fractures (OR 1.06 per unit increase, p = 0.006). Conclusions We report the largest independent study of CoC bearing fractures to date. The risk of revision for CoC bearing fracture is very low but previous studies have underestimated this risk. There is good evidence that the latest generation of ceramic has greatly reduced the odds of head fracture but not of liner fracture. Small head size and high patient BMI are associated with an increased risk of ceramic bearing fracture. Cite this article: Bone Joint J 2017;99-B:1012–19.

Abstract
AIMS The aim of this study was to compare the effectiveness of a femoral nerve block and a periarticular infiltration in the management of early post-operative pain after total knee arthroplasty (TKA). PATIENTS AND METHODS A pragmatic, single centre, two arm parallel group, patient blinded, randomised controlled trial was undertaken. All patients due for TKA were eligible. Exclusion criteria included contraindications to the medications involved in the study and patients with a neurological abnormality of the lower limb. Patients received either a femoral nerve block with 75 mg of 0.25% levobupivacaine hydrochloride around the nerve, or periarticular infiltration with 150 mg of 0.25% levobupivacaine hydrochloride, 10 mg morphine sulphate, 30 mg ketorolac trometamol and 0.25 mg of adrenaline all diluted with 0.9% saline to make a volume of 150 ml. RESULTS A total of 264 patients were recruited and data from 230 (88%) were available for the primary analysis. Intention-to-treat analysis of the primary outcome measure of a visual analogue score for pain on the first post-operative day, prior to physiotherapy, was similar in both groups. The mean difference was -0.7 (95% confidence interval (CI) -5.9 to 4.5; p = 0.834). The periarticular group used less morphine in the first post-operative day compared with the femoral nerve block group (74%, 95% CI 55 to 99). The femoral nerve block group reported 39 adverse events, of which 27 were serious, in 31 patients and the periarticular group reported 51 adverse events, of which 38 were serious, in 42 patients up to six weeks post-operatively. None of the adverse events were directly attributed to either of the interventions under investigation. CONCLUSION Periarticular infiltration is a viable and safe alternative to femoral nerve block for the early post-operative relief of pain following TKA.

Abstract
OBJECTIVE Cam hip shape morphology is a recognised cause of femoroacetabular impingement (FAI) and is associated with hip osteoarthritis. Our aim was to systematically review the available epidemiological evidence assessing the prevalence of cam hip shape morphology in the general population and any studied subgroups including subjects with and without hip pain. DESIGN All studies that reported the prevalence of cam morphology, measured by alpha angles, in subjects aged 18 and over, irrespective of study population or presence of hip symptoms were considered for inclusion. We searched AMED, MEDLINE, EMBASE, CINAHL and CENTRAL in October 2015. Two authors independently identified eligible studies and assessed risk of bias. We planned to pool data of studies considered clinically homogenous. RESULTS Thirty studies met inclusion criteria. None of the included studies were truly population-based: three included non-representative subgroups of the general population, 19 included differing clinical populations, while eight included professional athletes. All studies were judged to be at high risk of bias. Due to substantial clinical heterogeneity meta analysis was not possible. Across all studies, the prevalence estimates of cam morphology ranged from 5 to 75% of participants affected. We were unable to demonstrate a higher prevalence in selected subgroups such as athletes or those with hip pain. CONCLUSIONS There is currently insufficient high quality data to determine the true prevalence of cam morphology in the general population or selected subgroups. Well-designed population-based epidemiological studies that use homogenous case definitions are required to determine the prevalence of cam morphology and its relationship to hip pain.

Abstract
INTRODUCTION Total knee arthroplasty (TKA) surgery causes postoperative pain. The use of perioperative injections around the knee containing local anaesthetic, opiates and non-steroidal anti-inflammatory drugs has increased in popularity to manage pain. Theoretical advantages include reduced requirements for analgesia and earlier mobilisation. We propose a single-centre randomised controlled trial of multimodal periarticular anaesthetic infiltration versus femoral nerve anaesthetic blockade as analgesia for TKA. The aim is to determine, in patients undergoing TKA, if there is a difference in patient-reported pain scores on the visual analogue scale (VAS) prior to physiotherapy on day 1 postoperatively between treatment groups. METHODS AND ANALYSIS Patients undergoing a primary unilateral TKA at University Hospitals Coventry and Warwickshire Hospitals will be assessed for eligibility. A total of 264 patients will provide 90% power to detect a difference of 12 mm on the VAS on day 1 postoperatively at the 5% level. The trial will use 1:1 randomisation, stratified by mode of anaesthetic. Primary outcome measure will be the VAS for pain prior to physiotherapy on day 1. Secondary outcome measures include VAS on day 2, total use of opiate analgesia up to 48 h, ordinal pain scores up to 40 min after surgery, independent functional knee physiotherapist assessment on days 1 and 2. Oxford knee Scores (OKS), EuroQol (EQ-5D) and Douleur Neuropathic Pain Scores (DN2) will be recorded at baseline, 6 weeks and 12 months. Adverse events will be recorded up to 12 months. Analysis will investigate differences in VAS on day 1 between the two treatment groups on an intention-to-treat basis. Tests will be two-sided and considered to provide evidence for a significant difference if p values are less than 0.05. ETHICS AND DISSEMINATION NRES Committee West Midlands, 23 September 2013 (ref: 13/WM/0316). The results will be disseminated via peer-reviewed publications and conference presentations. TRIAL REGISTRATION NUMBERS ISRCTN 60611146 and EUDRACT Number 2013-002439-10 (protocol code number PAKA-33601-AS117013); Pre-results.

Abstract
BACKGROUND There has been major concern about the 'over-representation' of Black and ethnic minority groups amongst people detained under the Mental Health Act (MHA). We explored the effect of patient ethnicity on detention following an MHA assessment, once confounding variables were controlled for. METHOD Prospective data were collected for all MHA assessments over 4-month periods in the years 2008, 2009, 2010 and 2011 each in three regions in England: Birmingham, West London and Oxfordshire. Logistic regression modelling was conducted to predict the outcome of MHA assessments - either resulting in 'detention' or 'no detention'. RESULTS Of the 4423 MHA assessments, 2841 (66%) resulted in a detention. A diagnosis of psychosis, the presence of risk, female gender, level of social support and London as the site of assessment predicted detention under the MHA. Ethnicity was not an independent predictor of detention. CONCLUSIONS There is no evidence for that amongst those assessed under the MHA, ethnicity has an independent effect on the odds of being detained.

Abstract
BackgroundBlack and minority ethnic (BME) service users experience adverse pathways into care. Ethnic differences are evident even at first-episode psychosis (FEP); therefore, contributory factors must operate before first presentation to psychiatric services. The ENRICH programme comprised three interlinked studies that aimed to understand ethnic and cultural determinants of help-seeking and pathways to care.Aims and objectivesStudy 1: to understand ethnic differences in pathways to care in FEP by exploring cultural determinants of illness recognition, attribution and help-seeking among different ethnic groups. Study 2: to evaluate the process of detention under the Mental Health Act (MHA) and determine predictors of detention. Study 3: to determine the appropriateness, accessibility and acceptability of generic early intervention services for different ethnic groups.MethodsStudy 1: We recruited a prospective cohort of FEP patients and their carers over a 2-year period and assessed the chronology of symptom emergence, attribution and help-seeking using semistructured tools: the Nottingham Onset Schedule (NOS), the Emerging Psychosis Attribution Schedule and the ENRICH Amended Encounter Form. A stratified subsample of user–carer NOS interviews was subjected to qualitative analyses. Study 2: Clinical and sociodemographic data including reasons for detention were collected for all MHA assessments conducted over 1 year (April 2009–March 2010). Five cases from each major ethnic group were randomly selected for a qualitative exploration of carer perceptions of the MHA assessment process, its outcomes and alternatives to detention. Study 3: Focus groups were conducted with service users, carers, health professionals, key stakeholders from voluntary sector and community groups, commissioners and representatives of spiritual care with regard to the question: ‘How appropriate and accessible are generic early intervention services for the specific ethnic and cultural needs of BME communities in Birmingham?’ResultsThere were no ethnic differences in duration of untreated psychosis (DUP) and duration of untreated illness in FEP. DUP was not related to illness attribution; long DUP was associated with patients being young (< 18 years) and living alone. Black patients had a greater risk of MHA detention, more criminal justice involvement and more crisis presentations than white and Asian groups. Asian carers and users were most likely to attribute symptoms to faith-based or supernatural explanations and to seek help from faith organisations. Faith-based help-seeking, although offering comfort and meaning, also risked delaying access to medical care and in some cases also resulted in financial exploitation of this vulnerable group. The BME excess in MHA detentions was not because of ethnicity per se; the main predictors of detention were a diagnosis of mental illness, presence of risk and low level of social support. Early intervention services were perceived to be accessible, supportive, acceptable and culturally appropriate. There was no demand or perceived need for separate services for BME groups or for ethnic matching between users and clinicians.ConclusionsStatutory health-care organisations need to work closely with community groups to improve pathways to care for BME service users. Rather than universal public education campaigns, researchers need to develop and evaluate public awareness programmes that are specifically focused on BME groups.FundingThe National Institute for Health Research Programme Grants for Applied Research programme.

Abstract
Intra-operative, peri-articular injection of local anaesthesia is an increasingly popular way of controlling pain following total knee replacement. At the same time, the problems associated with allogenic blood transfusion have led to interest in alternative methods for managing blood loss after total knee replacement, including the use of auto-transfusion of fluid from the patient's surgical drain. It is safe to combine peri-articular infiltration with auto-transfusion from the drain. We performed a randomised clinical trial to compare the concentration of local anaesthetic in the blood and in the fluid collected in the knee drain in patients having either a peri-articular injection or a femoral nerve block. Clinically relevant concentrations of local anaesthetic were found in the fluid from the drains of patients having peri-articular injections (4.92 μg/ml (sd 3.151)). However, none of the patients having femoral nerve blockade had detectable levels. None of the patients in either group had clinically relevant concentrations of local anaesthetic in their blood after re-transfusion. The evidence from this study suggests that it is safe to use peri-articular injection in combination with auto-transfusion of blood from peri-articular drains during knee replacement surgery.

Abstract
BACKGROUND Hyper-homocyst(e)inemia is an independent risk factor for atherosclerotic vascular disease in patients with end-stage renal disease (ESRD), although optimal treatment remains unknown. This randomized, double-blind, placebo-controlled study was designed to measure the effect of high-dose oral vitamin B(12) and folic acid on predialysis total homocyst(e)ine levels in patients with ESRD. METHODS We studied 81 hemodialysis patients who had hyper-homocyst(e)inemia (>16 micromol/L) on varied doses of a multivitamin containing 1 mg of folic acid/day. After screening blood work, all patients were switched to daily multivitamin therapy, including 1 mg of folic acid for four weeks. For all patients, vitamin B(12), 1 mg/day, was added for an additional four weeks. Patients were then randomized to receive four weeks of 0, 5, or 20 mg of folic acid in addition to the multivitamin and vitamin B(12) (all given daily). RESULTS Screening homocyst(e)ine levels (mean 27.7 micromol/L) decreased by 19.2% after four weeks of treatment with a daily multivitamin containing 1 mg of folic acid (P < 0.001). Homocyst(e)ine levels were reduced further from 22.3 to 18.6 micromol/L (mean reduction 16.7%, 95% CI 11.8 to 21.6%, P < 0.001) after four weeks of therapy with vitamin B(12) (1 mg/day). There was no significant difference in mean reduction of homocyst(e)ine levels after therapy with high-dose folic acid compared with placebo (P = 0.35). CONCLUSIONS The optimal oral treatment of hyper-homocyst(e)inemia in hemodialysis patients consists of 1 mg of folic acid and 1 mg of oral vitamin B(12) daily. Whether this treatment will lower the risk of future atherosclerotic vascular events remains to be investigated.

Abstract
OBJECTIVE Familial hypercholesterolemia (FH), an inherited autosomal dominant disorder of lipoprotein metabolism, is associated with premature atherosclerosis. The recommended pediatric therapy consists of dietary intervention and, when necessary, treatment with bile acid-binding resins. However, compliance has been poor in many children. Therefore, our objectives were to determine the efficacy, safety, and tolerance of the short-term use of lovastatin, a 3-hydroxy 3-methylglutaryl coenzyme A reductase inhibitor, in the control of severe FH in a male pediatric population and to evaluate the dose-response relationship. METHODS Sixty-nine male patients with FH 12.9 +/- 2.4 years of age (mean +/- SD) participated in this multicenter, randomized, double-blind trial. After a 4-week placebo period, the patients were allocated to four treatment groups (lovastatin 10, 20, 30, 40 mg/d) for 8 weeks. Plasma lipid and apolipoprotein (Apo) concentrations were measured every 2 weeks. Clinical and laboratory evidence of adverse events was monitored periodically throughout the study. RESULTS All lovastatin doses reduced total cholesterol (-17% to -29%), low density lipoprotein cholesterol (-21% to -36%), and ApoB (-19% to -28%) concentrations. A dose-response relationship was seen, and between-group comparisons showed that results were significantly improved up to a dose of 30 mg/d. We observed a 7% increase in high-density lipoprotein cholesterol and a 4% increase in ApoA1 concentrations. The medication was well tolerated by all patients. No serious clinical adverse experience was reported. Lovastatin increased aspartate aminotransferase concentrations, but there was no evidence of a dose-response relationship, and no value exceeded two times the upper limit of normal. No significant change in alanine aminotransferase was observed. Three patients had marked (more than three times the upper limit of normal) asymptomatic elevations in their creatine kinase values, which returned spontaneously to normal, and no action was required regarding the drug.

Abstract
We treated selected patients with retinoblastoma with xenon arc photocoagulation between February 1974 and August 1987. Of 790 individual tumors in 410 affected eyes, 45 were treated by this technique. Overall photocoagulation alone was successful in eradicating 76% of the tumors, while in 24% of the tumors additional treatment with cryotherapy, plaque radiotherapy, external beam radiotherapy, or enucleation was necessary. In cases where the tumor was less than or equal to 3.0 mm in diameter and 2.0 mm in thickness and was confined to the sensory retina, without seeding into the adjacent vitreous, tumor destruction was achieved with photocoagulation. The mean number of photocoagulation sessions needed for complete tumor regression was 2.5. Photocoagulation alone was generally unsuccessful for tumors greater than 4.5 mm in diameter and 2.5 mm in thickness, and supplemental treatment with other modalities was often necessary in such cases. Based on observations in these patients, we point out certain misconceptions regarding photocoagulation of retinoblastomas and define our current indications and contraindications for this treatment modality.

Abstract
Between February 1974 and August 1987, we treated 67 retinoblastomas in 47 eyes of 45 patients with cryotherapy (triple freeze-thaw technique). Overall, cryotherapy eradicated 53 (79%) of the tumors, whereas additional treatment with episcleral plaque radiotherapy, external beam radiotherapy, or enucleation was necessary in 14 (21%) of the tumors. Tumor destruction was achieved with one or more cryotherapy treatments in all cases in which the tumor was no greater than 2.5 mm in diameter and 1.0 mm in thickness, and in which the tumor was confined to the sensory retina without seeding into the adjacent vitreous humor. We therefore recommend cryotherapy in such cases. Cryotherapy alone failed in 14 larger tumors, ten of which had clinical evidence of vitreous seeding by tumor cells. Cryotherapy is therefore contraindicated in cases of vitreous seeding or if the tumor exceeds 3.5 mm in diameter and 2.0 mm in thickness. Cryotherapy can be successful for tumors up to 3.5 mm in diameter and 2.0 mm in thickness, but more than one treatment may be necessary.

Abstract
We examined the effect of nutritional rehabilitation in cystic fibrosis patients with severe disease. Thirteen malnourished patients (seven males, six females, age 7-27 yr) were studied over 7-16 mo. Oral supplementation was attempted initially in 12 patients (mean duration 6.7 mo); only 2 patients gained weight, 2 withdrew, and 1 died. The remaining 7 patients failed to achieve adequate weight gain and were commenced on nasogastric supplementation with a semisynthetic formula. An additional patient was entered without a prior period of oral supplementation because of the severity of malnutrition. Weight gain was achieved in 7 of 8 patients with nasogastric supplementation (mean duration 6.4 mo). Weight gain was associated with an increase in lean body mass, total body fat, and height velocity. While pulmonary function and biochemical parameters were unchanged, patient well-being improved and episodes of pneumonia decreased.
