Managing magnets: An audit of introduction of the Royal College of Emergency Medicine Best Practice Guideline.

AIM: To evaluate management of children and young people presenting to the Emergency Department (ED) with magnet ingestion before and after new guidance. METHODS: In May 2021, a National Patient Safety Agency and Royal College of Emergency Medicine (RCEM) Best Practice Guideline about management of ingested magnets was published. This was implemented in our department. Children and young people presenting after magnet ingestion were identified from SNOMED (coded routinely collected data) and X-ray requests between January 2016 and March 2022. Management was compared to national guidance. RESULTS: There were 138 patient episodes of magnet ingestion, with a rising incidence over the 5-year period. Following introduction of the guideline, there was a higher incidence of admission (36% vs. 20%) and operative intervention (15.7% vs. 8%). Use of follow-up X-ray increased from 56% to 90%. There was substantial variation in the management prior to guidance which reduced after introduction of the RCEM guidance. CONCLUSION: Management of magnet ingestion has become more standardised since introduction of the National RCEM Best Practice Guideline, but there is still room for improvement.

Linfoma vitreorretiniano: un reto diagnóstico / Vitreoretinal lymphoma: A diagnostic challenge

Se presenta el caso de un varón de 66años remitido por uveítis posterior con edema macular quístico recurrente en relación con posible enfermedad de Lyme previamente tratada. Debido a la recurrencia del edema macular pese al tratamiento corticoideo sistémico y local con dexametasona intravítrea, se instaura tratamiento biológico con adalimumab. Durante el seguimiento el paciente desarrolla lesiones subretinianas bilaterales compatibles con linfoma vitreorretiniano, por lo que se realiza vitrectomía, confirmando el diagnóstico de linfoma de célulaB grande.Se inicia tratamiento con quimioterapia sistémica con BRAM (carmustina, metotrexato, ara-C y rituximab), con buena respuesta. Dos años después, el paciente permanece sin recurrencias a nivel ocular ni sistémico.El linfoma vitreorretiniano es un tipo poco frecuente de linfoma primario del sistema nervioso central. El diagnóstico se ve frecuentemente retrasado debido a la inespecificidad de su sintomatología, que simula una uveítis posterior crónica; de ahí la importancia de la sospecha diagnóstica. (AU)

A 66-year-old man with posterior uveitis and recurrent cystic macular edema related to possible previously treated Lyme disease is presented. Due to the recurrence of macular edema despite systemic and local corticosteroid treatment with intravitreal dexamethasone, biological treatment with adalimumab was established. During follow-up, the patient developed bilateral subretinal lesions compatible with vitreoretinal lymphoma, so vitrectomy was performed, confirming the diagnosis of large B-cell lymphoma.Treatment with systemic chemotherapy with BRAM (carmustine, metotrexate, ara C, and rituximab) was started with a good answer. Two years later, the patient remains without ocular or systemic recurrences.Vitreoretinal lymphoma is a rare type of primary central nervous system lymphoma. The diagnosis is frequently delayed due to the nonspecific symptoms, which mimic chronic posterior uveitis, hence the importance with a diagnostic suspicion. (AU)

Vitreoretinal lymphoma: a diagnostic challenge.

A 66-year-old man with posterior uveitis and recurrent cystic macular edema related to possible previously treated Lyme disease is presented. Due to the recurrence of macular edema despite systemic and local corticosteroid treatment with intravitreal dexamethasone, biological treatment with Adalimumab was established. During follow-up, the patient developed bilateral subretinal lesions compatible with Vitreoretinal Lymphoma (VRL), so vitrectomy was performed, confirming the diagnosis of large B-cell lymphoma. Treatment with systemic chemotherapy with BRAM-Carmustine, Metrotexate, Ara C, and Rituximab was started with a good answer. Two years later, the patient remains without ocular or systemic recurrences. Vitreoretinal Lymphoma is a rare type of primary central nervous system lymphoma. The diagnosis is frequently delayed due to the nonspecific symptoms, which mimic chronic posterior uveitis, hence the importance with a diagnostic suspicion.

Resource utilization and convalescent care cost in neonatal opioid withdrawal syndrome.

BACKGROUND: Neonatal opioid withdrawal syndrome (NOWS) is a growing public health problem associated with complex and prolonged medical care and a significant resource utilization burden. The objective of this study was to compare the cost of different convalescent care settings for infants with NOWS. METHODS: Retrospective comparison study of infants with NOWS discharged directly from NICU, transferred to an acute care pediatric floor (PPCU) or rehabilitation hospital (PRH). Primary outcomes were length of stay (LOS) and cost of stay (COS). RESULTS: Infants had 1.3 (95% CI: 1.1,1.6) times and 2.5 (95% CI: 2.1,3.1) times significantly longer mean LOS for PPCU and RH discharges compared to NICU discharges. NICU discharged infants had the lowest mean COS ($25,745.00) and PRH the highest ($60,528.00), despite PRH having a lower cost per day. PRH discharged infants had higher rates of methadone and benzodiazepine and less buprenorphine exposure than NICU/PPCU discharged. Infants born to mothers on marijuana and buprenorphine had a 28% lower mean COS compared to unexposed infants. Median treatment cumulative morphine doses were six-fold higher for PRH than NICU discharge. CONCLUSIONS: Infants transferred to convalescence care facilities had longer and more costly admissions and received more medication. However, there may be a role for earlier transfer of a subset of infants at-risk for longer LOS as those exposed to methadone and/or benzodiazepines. Further studies exploring differences in resource utilization, convalescent care delivery and cost expenditure are recommended.

[Extranodal B-cell lymphoma in the distal femur with pre-existing CRMO]. / Extranodales B-Zell-Lymphom im distalen Femur bei vorbestehender CRMO.

CRMO is a rare form of nonbacterial osteomyelitis, which is mainly found in children. The diagnosis is complex because bone tumors or lymphoma must also be excluded. The case report describes the development of a solitary femoral lymphoma on the basis of a known CRMO disease as well as the differential diagnostic pitfalls.

[Update in abdominal surgery]. / Evolution en chirurgie abdominale. Avancées techniques, collaboration intra et inter hospitalière.

During the last decade minimal invasive approach progressed in all sectors of abdominal surgery. Technological improvements allowed to perform more complex procedures laparoscopically with increased safety. The implementation of pre-, per- and postoperative protocols with an adaptation of surgical, anesthetic and analgesia methods and the patient's involvement in the healing process led to enhanced recovery after surgery. The centralization of complex esophageal and pancreatic surgery established the CHU of Liège as a tertiary referral institution for complex oncological surgery thanks to a large cooperation with regional hospitals.

La dernière décennie a vu progresser l'approche mini-invasive dans tous les domaines de la chirurgie abdominale. Les améliorations technologiques permettent de réaliser des interventions toujours plus complexes en laparoscopie avec une sécurité accrue. La systématisation de la prise en charge pré-, per- et postopératoire, avec une adaptation des techniques de chirurgie, d'anesthésie et d'analgésie, et une implication du patient dans ce processus ont abouti à une réhabilitation accélérée. La centralisation de la chirurgie complexe de l'oesophage et du pancréas a permis de créer une structure de référence en chirurgie oncologique complexe au CHU de Liège grâce à une large collaboration interhospitalière régionale.

[Enhanced recovery after surgery in colorectal surgery]. / La réhabilitation améliorée après chirurgie colorectale.

Enhanced recovery after surgery (ERAS) in colorectal surgery consists of multidisciplinary, multimodal, and patient-centred care. The implementation of pre-, intra-, and post-operative measures mitigates the surgical stress, the inflammatory reaction, and their consequences. The elements of this protocol are evidence-based medicine. This allows improved and accelerated recovery. Consequently, ERAS reduces the incidence of medical complications by 50 %, including fewer infectious complications, and a possible positive impact on survival after oncologic surgery. Hospital length of stay is shortened. There is no contraindication to ERAS, which must be used for all patients undergoing colorectal surgery. Adaptation of the protocol will nevertheless be necessary in the event of urgent surgery.

La réhabilitation améliorée après chirurgie (RAC) colorectale est une prise en charge multidisciplinaire et multimodale, centrée sur le patient. La mise en place de mesures pré-, per- et postopératoires réduit la réponse au stress chirurgical, la réaction inflammatoire et leurs conséquences. Ce protocole de soins, basé sur des preuves scientifiques, permet une récupération améliorée et accélérée. L'incidence des complications médicales est, secondairement, réduite de 50 %. La réhabilitation améliorée se traduit par une diminution significative de la durée d'hospitalisation, une diminution des complications infectieuses et, probablement, par un impact positif sur la survie après chirurgie oncologique. Il n'y a pas de contre-indication à la RAC qui doit donc être proposée à tous les patients devant subir une chirurgie colorectale. Une adaptation du protocole sera néanmoins nécessaire en cas de chirurgie urgente.

[Hand ischemia and increased CRP level in a 75-year-old female patient]. / Handischämie und erhöhter CRP-Wert einer 75-jährigen Patientin.

The complexity of the diagnosis and therapy as well as the deficits in care are presented on the basis of the casuistry of a 75-year-old female patient with giant cell arteritis and a complicative course.

Elderly patients over 70 years benefit from enhanced recovery programme after colorectal surgery as much as younger patients.

AIM OF THE STUDY: Enhanced recovery programme (ERP) reduces length of hospital stay (LOS) and postoperative complications after colorectal surgery. ERP is feasible and effective in elderly patients. We tested the hypothesis of non-inferiority for elderly patients as compared to younger patients with regard to LOS. PATIENTS AND METHODS: The first 302 consecutive patients scheduled for colorectal surgery and prospectively introduced in our audit database were retrospectively analysed. LOS (primary endpoint), postoperative complications, and adherence to the ERP of elderly (≥70 years, n=100) were compared with those of younger patients (n=202). The same ERP was used in all patients. Non-inferiority hypothesis for LOS was tested using the confidence interval method. Secondary endpoints were compared using the Mann-Whitney U and the Chi2 tests. RESULTS: Except for age patients' demographic data were not different in both groups: 53.8 (17-69) vs. 76.8 (70-90) years. The actual LOS were 3.5 [2-7] and 4.0 [3-7] days in the young and elderly group, respectively. The difference in median LOS between the two groups was 0 (95% CI, -0.97-0.97), demonstrating non-inferiority. Although with more risk factors (anaemia, COPD, cardiac disease, and cancer, P<0.05), elderly patients experienced neither more postoperative medical (17.0 vs. 16.3 %) nor surgical (19.0 vs. 22.3 %) complications than young patients. The adherence to protocol was slightly less in elderly (16 [15-18] vs. 17 [16-18], P=0.05). CONCLUSION: Not only ERP is feasible in seniors, but elderly patients benefit from this perioperative care as much as younger patients. CLINICAL TRIALS REGISTRATION: NCT03620851.

CAPS on the move: Crafting an approach to recruitment for a randomized controlled trial of community gardening.

OBJECTIVE: To describe and evaluate recruitment approaches for a randomized controlled trial (RCT) of community gardening in Denver, Colorado. (ClinicalTrials.gov: NCT03089177). METHODS: We used community and staff feedback to adapt our recruitment approach from year 1 to year 2 of a multi-year RCT to address health behaviors related to cancer prevention. In year 2, we added a full-time recruitment coordinator, designed and implemented a tracking spreadsheet, and engaged advisory committee members, local garden leaders, and health partners in planning and outreach. Screening and consent rates, staff time and costs for years 1 and 2 are compared. RESULTS: In year 1, recruitment methods yielded 136 initial contacts, 106 screenings and 64 consented participants. In year 2, enhanced staffing and outreach yielded 257 initial contacts, 193 screenings, and 123 consented participants. Personal referrals, health fairs, NextDoor, and fliers yielded the highest percentage of consented participants. School and community meetings yielded the lowest yield for potential participants. Spanish-speaking participants were mostly recruited by direct methods. Compared to year 1 recruitment, which required 707 h of staff time and cost $14,446, year 2 recruitment required 1224 h of staff time and cost $22,992. Average cost for retained participants was $226 (year 1) and $186 (year 2). DISCUSSION: Those planning pragmatic clinical trials with recruitment in multi-ethnic communities can use the results from this study to understand the efficacy of techniques, and to budget costs for recruitment. While our culturally-tailored recruitment methods cost more, they provided more effective and efficient ways to reach recruitment goals.

Prolene hernia system versus Lichtenstein repair for inguinal hernia: a meta-analysis.

BACKGROUND: Lichtenstein repair is standard practice for inguinal herniorrhaphy, but there is increasing public concern in the use of mesh and postoperative chronic pain. New mesh technology, such as the prolene hernia system, has a preperitoneal component to reinforce the myopectineal orifice aim to reduce the risk of recurrence and chronic pain. This meta-analysis compares outcomes using prolene hernia system versus lichenstein repair for inguinal hernias. METHODS: Randomized-controlled trials comparing prolene hernia system and Lichtenstein repair were identified using Embase, Medline, and published conference abstracts. Primary outcomes were recurrence and chronic pain. Secondary outcomes were mean operating time, composite complications, surgical reintervention, and time to normal activities. Odds ration and standardized mean differences were calculated. RESULTS: 1377 hernia repairs were identified from a total of 7 trials. Mean follow-up was 12-91 months. There was no difference between the techniques for recurrence [pooled analysis odds ratio: 0.86 (95% CI 0.32-2.28); p = 0.76] and chronic pain [pooled analysis odds ratio: 1.00 (95% CIs 0.65-1.55); p = 1]. Prolene hernia system demonstrated a shorter time to return to normal activities [pooled weighted mean difference - 0.54 (95% CI - 1.07 to - 0.01); p = 0.04]. Other outcomes were similar in mean operating time, composite complications, and surgical reintervention. CONCLUSION: Both prolene hernia system and Lichenstein repair appear comparable acceptable techniques for inguinal herniorrhaphy. Further longer-term studies of new mesh technologies will improve information available to surgeons and their patients.

Antimicrobial efficiency of mouthrinses versus and in combination with different photodynamic therapies on periodontal pathogens in an experimental study.

BACKGROUND AND OBJECTIVE: In the therapy of destructive periodontal disease, chemical antimicrobial agents and increasingly photodynamic therapy (PDT) play an important adjunctive role to standard mechanical anti-infective treatment procedures. However, both antiseptic methods have their shortcomings in terms of eliminating periodontal pathogens. The aim of the study was to compare the antibacterial efficacy of different antiseptic mouthrinses, of a conventional and a new, modified PDTplus as well as of the different antiseptic mouthrinses combined with either the conventional or the modified PDTplus against periopathogens. MATERIAL AND METHODS: Six representative periodontitis-associated bacterial strains were grown for 24 h under anaerobic conditions. After mixing the individual cell pellets they were exposed to 10 different antiseptic mouthrinse formulations: chlorhexidine (0.2%, 0.06%, CHX); CHX + cetylpyridinium chloride (each 0.05%); sodium hypochlorite (0.05%); polyhexanide (0.04%, PHMB1; 0.1%, PHMB2); octenidine dihydrochloride (0.1%); fluoride (250 ppm); essential oils; povidone iodine (10%); and saline (0.9%, NaCl) as control. Furthermore, the bacteria were treated with conventional PDT based on light-emitting diodes and a new modified photodisinfection combining photosensitizer with hydrogen peroxide to PDTplus also based on light-emitting diodes. In addition to the single treatments, a combined application of antiseptic exposure followed by use of PDT or PDTplus was performed. The microbial viability was characterized by analyzing colony growth and fluorescence-based vitality proportions. RESULTS: Nearly all mouthrinses caused a statistically significant growth inhibition. The most effective antiseptics, CHX (0.2%), CHX/cetylpyridinium chloride and octenidine dihydrochloride, inhibited bacterial growth completely. Conventional PDT resulted in moderate reduction of colony growth. The modified PDTplus achieved maximum antimicrobial effect. The combination of antiseptic exposure and PDT against periopathogens predominantly increased antibacterial efficacy compared to the single applications. The mouthrinse containing essential oil seemed to interfere with PDT. CONCLUSION: A combination therapy of preceding chemotherapeutical exposure and subsequent photodisinfection may be a more effective and promising antibacterial treatment than single applications of the antiseptic methods. The modified PDTplus using oxygen-enriched toluidine showed a superior antibacterial effect on periodontal pathogens to conventional PDT and to the majority of the investigated mouthrinses.

Thirty-days readmissions in pediatric surgery: The first U.K. experience.

INTRODUCTION: The aim of this study was to investigate readmissions within 30days of operation (ReAd) in the setting of a tertiary pediatric surgical practice in the UK. METHODS: Using Hospital Episode Statistics, cases that were readmitted within 30days of primary operation were identified retrospectively. Demographics including age, gender, preexisting comorbidities, diagnosis on primary admission and the treatment, length of stay, and diagnosis on readmission with treatment, including further surgical intervention, were collected from discharge summaries and hospital notes. Neonates were excluded from this study. Comorbidities, involving one or more systems, were also identified for each case of readmission. ReAds were classified into emergency and elective cohort depending on the nature of the primary operation. Outcomes were compared between these two groups. Data were quoted as median (range) unless indicated otherwise. Data were analyzed using SPSS software Desktop 22.0, using Mann-Whitney U and Chi-Squared tests, with a consideration that a P≤0.05 was significant. RESULTS: A total of 2378 procedures were performed during the study period. Elective cases, including day cases, accounted for 77% (n=1837) of all cases. The remaining 23% (n=541) were emergency cases. Total unplanned readmission rate within 30days (ReAd) was 2%. Further surgical procedures were required in 38%. Having excluded neonates, the most common primary procedure leading to readmission within 30days was appendicectomy (26%). Overall, the most common cause for readmission within 30days was postoperative infection (30%). The ReAd in emergency cohort was 3.5% in comparison to 1.5% in elective, which was significantly different (P value=0.007). CONCLUSION: Readmission within thirty days of primary procedure in pediatric surgery has little published data. An efficient discharge planning may play a vital role in preventing unwanted readmission. Elective operations had a significantly lower readmission rate than emergency operations. Having excluded neonates, appendicectomy was found to be the most common operation associated with readmission in the pediatric surgical practice. Although widely used as quality care indicator in adults, more studies are required to validate readmission rate as a quality of care indicator in pediatric surgery practice.

MKS1 mutations cause Joubert syndrome with agenesis of the corpus callosum.

Joubert syndrome (JS) is a clinically and genetically heterogeneous ciliopathy characterized by episodic hyperpnea and apnea, hypotonia, ataxia, cognitive impairment and ocular motor apraxia. The "molar tooth sign" is pathognomonic of this condition. Mutations in the MKS1 gene are a major cause of Meckel-Gruber syndrome (MKS), the most common form of syndromic neural tube defects, frequently resulting in perinatal lethality. We present the phenotype and genotype of a child with severe JS and agenesis of the corpus callosum (ACC). In our patient, a next generation sequencing (NGS) approach revealed the following two variants of the MKS1 gene: first, a novel missense variant [ c.240G > T (p.Trp80Cys)], which affects a residue that is evolutionarily highly conserved in mammals and ciliates; second, a 29 bp deletion in intron 15 [c.1408-35_1408-7del29], a founder mutation, which in a homozygous state constitutes the major cause of MKS in Finland. We review the MKS1-variants in all of the eleven JS patients reported to date and compare these patients to our case. To our knowledge, this is the first patient with Joubert syndrome and agenesis of the corpus callosum where a potentially causal genotype is provided.

Applying the Intervention Mapping protocol to develop a kindergarten-based, family-involved intervention to increase European preschool children's physical activity levels: the ToyBox-study.

Although sufficient physical activity is beneficial for preschoolers' health, activity levels in most preschoolers are low. As preschoolers spend a considerable amount of time at home and at kindergarten, interventions should target both environments to increase their activity levels. The aim of the current paper was to describe the six different steps of the Intervention Mapping protocol towards the systematic development and implementation of the physical activity component of the ToyBox-intervention. This intervention is a kindergarten-based, family-involved intervention implemented across six European countries. Based on the results of literature reviews and focus groups with parents/caregivers and kindergarten teachers, matrices of change objectives were created. Then, theory-based methods and practical strategies were selected to develop intervention materials at three different levels: (i) individual level (preschoolers); (ii) interpersonal level (parents/caregivers) and (iii) organizational level (teachers). This resulted in a standardized intervention with room for local and cultural adaptations in each participating country. Although the Intervention Mapping protocol is a time-consuming process, using this systematic approach may lead to an increase in intervention effectiveness. The presented matrices of change objectives are useful for future programme planners to develop and implement an intervention based on the Intervention Mapping protocol to increase physical activity levels in preschoolers.

Developing the intervention material to increase physical activity levels of European preschool children: the ToyBox-study.

Early childhood is an important period for adopting positive health-related behaviours. More than 95% of European preschool children attend kindergartens, making these settings ideal for the implementation of health promotion interventions. The ToyBox-intervention addressed preschool children, their parents/caregivers and teachers. The aim of the intervention was to improve four energy balance-related behaviours (i.e. healthy snacking, water consumption, physical activity and sedentary behaviour) by implementing a kindergarten-based, family-involved intervention in six European countries (Belgium, Bulgaria, Germany, Greece, Poland and Spain). The intervention material was developed following the intervention mapping protocol, taking into account local and cultural differences among the intervention countries. The present paper focuses on the development of the physical activity component of the intervention. Parental involvement was addressed by providing parents/caregivers with two newsletters, two tip cards and a poster. Teachers received a handbook with guidance on environmental changes in the classroom, 26 physical education sessions and suggestions for fun, interactive classroom activities aiming at total class participation to increase preschoolers' physical activity levels. The ToyBox-intervention material was distributed according to a standard time frame. Teachers received their material prior to the start of the intervention and parents/caregivers received their material during the intervention when each energy balance-related behaviour was implemented.

Concepts and strategies on how to train and motivate teachers to implement a kindergarten-based, family-involved intervention to prevent obesity in early childhood. The ToyBox-study.

The key person for the implementation of kindergarten-based behavioural interventions is the kindergarten teacher. When conducting intervention studies in kindergartens, training sessions are needed to train and motivate kindergarten teachers for programme implementation. This paper presents the systematic development of the teachers' trainings executed in the ToyBox-intervention - a kindergarten-based and family-involved obesity prevention programme for children aged 4-6. Based on concepts for the education of kindergarten teachers, on general strategies for successful programme implementation and on the ToyBox programme-specific requirements, the aims of the teachers' trainings were defined and an overall concept was deduced. Regarding the concept for the ToyBox teachers' training sessions, it is concluded that the training modules should focus on presenting information on the practical implementation of the intervention. Furthermore, these modules should also include self-efficacy enhancing components and should give kindergarten teachers opportunities to share experiences. Regarding the didactic methods applied in the ToyBox teachers' training sessions, constructivist learning approaches that facilitate active participation, reflective thinking and personal involvement were implemented. Emphasis was put not only on the content but especially on the didactic methods of teachers' trainings in order to enhance devotion to, and quality and sustainability of the ToyBox-intervention.

Designing and implementing teachers' training sessions in a kindergarten-based, family-involved intervention to prevent obesity in early childhood. The ToyBox-study.

Since school-based interventions are mainly delivered by the school staff, they need to be well-trained and familiarized with the programme's aims, procedures and tools. Therefore, the institute, research group, governmental or non-governmental body in charge of the coordination and implementation of the programme needs to devote time and resources to train the school staff before programme's implementation. This is particularly crucial in multi-centre studies where more than one research teams are involved. Both research teams and school staff need to be trained, using standard protocols and procedures, to ensure that the intervention will be delivered in a standardized manner throughout the intervention centres. The ToyBox-intervention, a multi-component, kindergarten-based, family-involved intervention, focusing on water consumption, snacking, physical activity and sedentary behaviours in preschool children, was implemented over the academic year 2012-2013 in six European countries. As part of this intervention, three teachers' training sessions were delivered to motivate and train teachers in implementing the intervention. The local researchers were trained centrally before delivering the training sessions for the teachers and followed a common protocol using standardized presentations and procedures. The aim of the current paper is to describe the protocol and methodological issues related to the teachers' training sessions conducted within the ToyBox-intervention.

[Rheumatoid arthritis. Systemic inflammation and cardiovascular morbidity]. / Rheumatoide Arthritis. Systemische Entzündung und kardiovaskuläre Morbidität.

In recent years it could be shown that systemic inflammation, which typically occurs in chronic inflammatory rheumatic diseases, significantly contributes to cardiovascular morbidity and mortality. All rheumatic diseases inherit this enhanced risk for cardiovascular complications with rheumatoid arthritis being one of the most prominent. As the underlying pathophysiological mechanisms are very similar with respect to endothelial damage all rheumatic diseases and specifically rheumatoid arthritis should be monitored and treated with disease-modifying drugs and biological agents as consistently as possible to be able to improve the long-term outcome of affected patients as much as possible.
