Acute infectious osteomyelitis in children: new treatment strategies for an old enemy
No full textBackground: Acute osteomyelitis still represents a significant clinical challenge, with an increasing incidence in paediatric population. A careful assessment and a rapid diagnosis with proper timing and choice of empirical antimicrobial therapy are necessary to avoid sequelae. The initial treatment should consist of empirical antibiotic therapy, to cover the major responsible pathogens in each age group. Data sources: We made a literature search with PubMed and Cochrane database from 2000 to 2019 in English, French, and Spanish languages using the key words “osteomyelitis, children, clinical, diagnosis, and treatment”. Results: The child’s clinical features, age, and the microbiological profile of the geographic area should be evaluated for diagnosis and in the choice of antibiotic treatment. Latest data suggest the administration of intravenous antibiotics for a short period, with subsequent oral therapy, according to the improvement of clinical status and inflammatory markers. For children older than 3 months, the shift to oral medications is already possible after a short course of intravenous therapy, until recovery. The timing for the shift from cefazolin to cephalexin or cefuroxime, intravenous clindamycin to oral clindamycin, and intravenous ceftriaxone + oxacillin to oral equivalents will be decided according to the improvement of clinical status and inflammatory markers. We also present the approach to osteomyelitis due to difficult pathogens, such as Methicillin-resistant Staphylococcus aureus (MRSA) and Panton-Valentine leukocidin (PVL)-positive S. aureus infections. Conclusion: In this review, we present the current approach to the clinical diagnosis and management of osteomyelitis in childhood, with an update on recent recommendations, as a useful instrument to understand the rationale of antibiotic therapy
Refractory symptoms in paediatric palliative care: Can ketamine help?
No full textBackground: One of the main challenges for paediatric palliative care (PPC) is the management of concomitant, different and severe symptoms that frequently affect the quality of life of PPC patients and are often refractory to commonly used pharmacological treatments. Consequently, many efforts are still needed to find the best therapeutic options to handle these refractory conditions. Since the first synthesis of ketamine in the 1960s, its pharmacokinetic and pharmacodynamic properties have been largely investigated and its potential wide range of clinical applications has become clear. However, this molecule still receives poor attention in some areas, including in children and PPC. This narrative review analyses the use of ketamine in children and the potential extension of its applications in PPC in order to provide new options for treatment in the PPC setting. Methods: Scientific papers published before October 2020 on MEDLINE, EMBASE and the Cochrane Library were considered. The cited references of the selected papers and the authors' personal collections of literature were reviewed. The terms "palliative care", "ketamine", "neuropathic pain", "procedural pain", "status epilepticus", "refractory pain" and "child", adding "age: birth-18 years" on a further filter were used for the search. Discussion: The use of ketamine in PPC should be more widely considered due to its overall favourable safety profile and its efficacy, which are supported by an increasing number of studies, although in settings different from PPC and of mixed quality. Ketamine should be proposed according to a case-by-case evaluation and the specific diagnosis and the dosage and route of administration should be tailored to the specific needs of patients. Furthermore, there is evidence to suggest that ketamine is safe and efficacious in acute pain. These findings can prompt further research on the use of ketamine for the treatment of acute pain in PPC. Conclusion: Ketamine could be a suitable option after the failure of conventional drugs in the treatment of different refractory conditions in PPC
Echocardiographic assessment of pulmonary capillary wedge pressure by E/e' ratio: A systematic review and meta-analysis
No full textBackground: The reliability of echocardiographic methods for the assessment of pulmonary capillary wedge pressure (PCWP) is still a matter of debate. Since its first description, the E/e' ratio has been regarded as a suitable method. The aim of this study is to evaluate the evidence of how E/e' effectively estimates PCWP and its diagnostic accuracy for elevated PCWP. Methods: We systematically searched MEDLINE and Embase databases for studies investigating the agreement between E/e' and PCWP, from inception to July 2022. We limited our research to studies published from 2010 to date. Retrospective studies and studies on non-adult population were excluded. Results: Twenty-eight studies, involving a total of 1964 subjects, were included. The pooled analysis of the studies showed a modest correlation between E/e' and PCWP. The weighted average correlation (r) is 0.43 (95% CI 0.37–0.48). We found no significant differences between reduced and preserved ejection fraction groups. Thirteen studies analysed the diagnostic accuracy of E/e' for elevated PCWP. The AUC of receiver operating characteristic curves for PCWP >15 mmHg was estimated in the interval 0.6–0.91. Discussion: E/e' appears to have a modest correlation with PCWP and an acceptable accuracy for elevated PCWP. (PROSPERO number, CRD42022333462)
Diffusive author(s), cohesive author: Analysis of S/N (1994)
No full textThis study indicates the ways in which various aspects of the author(s) are brought forth in Dumb type’s performance art, the S/N production. Previous research has suggested a non-hierarchical organization of Dumb type and the absence of a “privileged author” in Dumb type’s collaborative work, S/N. However, the results that I have investigated from member’s interviews on the creative process of S/N along with my analysis of the recorded images of S/N, indicate a different aspect of the author(s). First, S/N was created through, so to speak, the collective ideas of the members of Dumb type. Further, S/N has at least nine quotations from previous performances, installations, and printed writings, besides the work-in-progress technique. Explicating one of the “author functions” as given by Michel Foucault, each text has plural subjects of the author. However, it has been revealed from members’ interviews that Teiji Furuhashi had a decision-making role in selecting the members’ ideas within the performance. Since then, S/N has had plural subjects of creation; however, Furuhashi is one of the subjects of creation along with the “privileged author.” S/N has plural authors (diffusive authors) yet at the same time, it has a “privileged author,” Teiji Furuhashi (cohesive author)
Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Up-date sulla gestione del dolore del bambino in Pronto Soccorso
No full textPain is a frequent symptom in paediatric population, especially in the emergency setting; nevertheless pain is poorly managed in clinical practice. The present paper aims to give an up-to-date analysis concerning paediatric pain in emergency units, as regards epidemiology, assessment, measurement and treatment, through a detailed systematic revision of the literature and an on-going clinical trial assessment carried out by analysing the relevant data available until March 2018. Among the many paediatric pain scales for different ages and situations and according to their efficacy and efficiency, FLACC scale, Wong-Baker scale and FLACC-r or NCCPC-R scale are proposed. Moreover, pharmacological and non-pharmacological strategies should always be considered; innovative strategies, new molecules and route of administration allow adequate therapies to be performed in many clinical situations. Emerging data suggest the need to carry out more research on pain prophylaxis, increase opioid drugs prescription in case of severe pain and reduce primary analgesia time. Therefore, an adequate management of pain in paediatric population in the emergency setting is still a goal to achieve. So, innovative organisational arrangements, training strategies addressed to health professionals, information and research are the instruments to imprint a real change in paediatric pain management in emergency units
COVID-19 pneumonia in lung transplant recipients: report of two cases
No full textCoronavirus disease 2019 (COVID-19) has been declared pandemic since March 2020. In Europe, Italy has been the first nation affected by this infection. In this paper we report anamnestic data, clinical features and therapeutic management of two lung transplant recipients with confirmed COVID-19 pneumonia. Both patients were in good clinical conditions prior to the infection and were on immunosuppression with calcineurin inhibitors (CNI), mycophenolate mofetil and corticosteroids. Whilst mycophenolate mofetil was withdrawn in both cases, CNI were suspended only in the second patient. The first patient always maintained excellent oxygen saturation throughout hospitalization with no need for additional oxygen therapy. He was discharged with a satisfactory pulmonary function and a complete resolution of radiological and clinical findings. However, at discharge SARS-CoV-2 RNA could still be detected in the nasopharyngeal swab and in the stools. The second patient required mechanical ventilation, had a progressive deterioration of his clinical conditions and had a fatal outcome. Further insight into SARS-CoV-2 infection is eagerly awaited to improve the outcome transplant recipients affected by COVID-19 pneumonia
