The Optimal Primary Treatment for Pediatric Perianal Abscess and Anal Fistula: A Systemic Review and Meta-Analysis

BackgroundPerianal abscesses and anal fistulas are common. The principle of intention-to-treat has not been considered in previous systemic reviews. Thus, the comparison between primary and post-recurrence management was confused, and the recommendation of primary treatment is obscure. The current study aims to identify the optimal initial treatment for pediatric patients.MethodsUsing PRISMA guidelines, studies were identified from MEDLINE, EMBASE, PubMed, Cochrane Library, and Google Scholar without any language or study design restriction. The inclusion criteria include original articles or articles with original data, studies of management for a perianal abscess with or without anal fistula, and patient age of <18 years. Patients with local malignancy, Crohn's disease, or other underlying predisposing conditions were excluded. Studies without analyzing recurrence, case series of <5, and irrelevant articles were excluded in the screening stage. Of the 124 screened articles, 14 articles had no full texts or detailed information. Articles written in a language other than English or Mandarin were translated by Google Translation first and confirmed with native speakers. After the eligibility process, studies that compared identified primary managements were then included in the qualitative synthesis.ResultsThirty-one studies involving 2507 pediatric patients met the inclusion criteria. The study design consisted of two prospective case series of 47 patients and retrospective cohort studies. No randomized control trials were identified. Meta-analyses for recurrence after initial management were performed with a random-effects model. Conservative treatment and drainage revealed no difference (Odds ratio [OR], 1.222; 95% Confidential interval [CI]: 0.615–2.427, p = 0.567). Conservative management had a higher risk of recurrence than surgery without statistical significance (OR 0.278, 95% CI: 0.109–0.707, p = 0.007). Compared with incision/drainage, surgery can prevent recurrence remarkably (OR 4.360, 95% CI: 1.761–10.792, p = 0.001). Subgroup analysis of different approaches within conservative treatment and operation was not performed for lacking information.ConclusionStrong recommendations cannot be made due to the lack of prospective or randomized controlled studies. However, the current study based on real primary management supports initial surgical intervention for pediatric patients with perianal abscesses and anal fistula to prevent recurrence.Level of evidenceType of study: Systemic review; Evidence level: Level II.     

Identifying Trends of Percutaneous Injuries at an Australian Dental School

ObjectivesThe aim of this study was to retrospectively examine trends in percutaneous exposure incidences (PEIs) at the School of Dentistry (SoD) from 2009 to 2019 and to report on the underreporting rate of PEIs, current attitudes, and awareness of PEI safety protocols from clinical staff and students at the SoD in 2019.MethodsRetrospective data were collected from deidentified archival incident reports from 2009 to 2019 from the SoD's incident reporting system (UQSafe and Legacy Database). Additionally, cross-sectional data were collected via the validated Percutaneous Exposure Incident Questionnaires (PEIQ) completed by clinical staff and students of the SoD in 2019.ResultsFrom the archival data, the majority (79.9%) of the 618 reported PEIs involved students. Local anaesthetic-related procedures were the most common cause in the archival (31.5%) and survey data (23.7%), whereas the needle-prick was the most common causative instrument in both data sets. Additionally, the finger was the most common site of injury found in the archival (53.0%) and survey data (52.8%). From 345 responses to the survey, 42.1% of PEIs sustained were not reported.ConclusionsStudents were at a higher risk of sustaining a PEI than staff members between 2009 and 2019. The reported knowledge on PEI classification and preventative measures is inadequate, suggesting that further PEI education is necessary. The study provides evidence of the trends in PEIs as well as data on the attitudes and awareness of student and staff at a dental teaching faculty to support the development of PEI safety management protocols.     

保留自主呼吸对于重度急性呼吸窘迫综合征患者的影响：弊大于利

急性呼吸窘迫综合征（ARDS）是临床上常见的以顽固性低氧为表现的呼吸功能不全或衰竭的综合征，肺不均一性是其主要病理生理特点。传统观点认为，保留ARDS患者自主呼吸有助于改善全身氧合。但是近年来发现，对于重度ARDS患者，保留患者自主呼吸会加重肺损伤，过强的自主呼吸会导致重度ARDS患者跨肺压升高、肺内气体摆动、肺水肿加重以及人机不同步，引起患者肺内炎症加重，氧合功能恶化，最终影响患者预后，增加病死率。本文就自主呼吸对重度ARDS患者呼吸功能的影响机制展开综述。     

Barriers to the use of patient safety information sources by community pharmacies

BackgroundWhen patient safety information is communicated across a regulatory jurisdiction or country, the potential to enhance the safety of community pharmacy practice is significant. While there currently exists a number of sources for patient safety information (e.g., websites, safety bulletins, online tools), knowledge of the barriers that may inhibit the use of such information sources within community pharmacies is limited.ObjectiveThis research explores community pharmacy manager use of Canadian patient safety information sources and the barriers that may limit the use of such sources.MethodsA qualitative research study design using semi-structured interviews was conducted with 15 community pharmacy managers in the Halifax Regional Municipality of Nova Scotia, Canada. The study explored how pharmacists access and engage a variety of information sources, including corporate intranets, websites, and tools provided by third party data base repositories. Interview data were analyzed using thematic analysis.ResultsFive general barriers were identified: lack of time to access information sources and its contents; too many sources of available information; too much information not relevant to community pharmacy practice; complexity navigating online information sources; and lack of community pharmacy involvement in source design.ConclusionWhile pharmacies do use safety information sources to enhance practice safety, their ability to incorporate this information is inhibited by their general lack of time available to access and read safety information, lack of knowledge about where to get this information, and lack of tailored information for the community pharmacy context. Future initiatives should address increasing information awareness of available sources, consolidating and reducing information overload of such sources, and packaging information to better fit with pharmacists’ needs.     

Colitis following the use of immune checkpoint inhibitors: A real-world analysis of spontaneous reports submitted to the FDA adverse event reporting system

BackgroundAlthough colitis has been reported in patients treated with immune checkpoint inhibitors (ICIs), associations between colitis and ICIs had not been thoroughly assessed in real-world studies. Here, we identified and characterized significant colitis-associated with ICIs.MethodsBased on the Food and Drug Administration Adverse Event Reporting System (FAERS) from January 2004 to December 2019, the disproportionality analysis and Bayesian analysis, including the reporting odds ratio (ROR), the proportional reporting ratio (PRR), the Bayesian confidence propagation neural network (BCPNN) and the multi-item gamma Poisson shrinker (MGPS) algorithms were adopted to data mining of the suspected adverse events of colitis after ICIs administrating. Clinical characteristics of patients with ICIs-associated colitis and the time to onset of colitis following different ICI regimens were collected.ResultsA total of 3786 reports of colitis adverse events were identified with ICIs. Seven ICI monotherapies were associated with the reporting of colitis. Statistically significant ROR, PRR, information component (IC), and empirical Bayesian geometric mean (EBGM) emerged for all ICI monotherapies and combination therapies. ICIs-associated colitis affected mostly male (53.51%), with a wide mean age range (60.65 to 72 years). Colitis adverse events were commonly reported in patients with melanoma and lung cancer. Adverse outcomes of colitis concerning ICI were mainly outcomes of hospitalization-initiated or prolonged and other serious. Among colitis cases, 17.43% cases of colitis concerning ICI lead to death. The adverse event of colitis occurred earliest in ipilimumab monotherapy with a median time to onset of 64.21 days (IQR: 27–69 days) among all monotherapies.ConclusionsICI may lead to severe and disabling ICIs-associated colitis during therapy. Analysis of FAERS data identified signals for adverse events of colitis with ICI regimens. Practitioners should consider the factors that may increase the likelihood of colitis. The findings support a continued surveillance and risk factor identification studies.

Adverse events due to unnecessary radiation exposure in medical imaging reported in Finland

IntroductionAdverse events in radiology are quite rare, but they do occur. Radiation safety regulations and the law obligate organizations to report certain adverse events, harm and near misses, especially events related to patients' health and safety. The aim of this study was to describe and analyse incidents related to radiation safety issues reported in Finland.MethodsThe data were collected from incident reports documented by radiology personnel concerning notifications of abnormal events in medical imaging made to the Radiation and Nuclear Safety Authority between 2010 and 2017. During these eight years, 312 reports were submitted. Only events reported from radiology departments were included; nuclear medicine, radiotherapy and animal radiology cases were excluded. The final number of reports was 293 (94%).ResultsThe majority of the 293 approved reports were related to computed tomography (CT, 68.3%) and to X-ray examinations (27.6%). Altogether 82.9% of those irradiated were adults, most of whom were exposed to unnecessary radiation through CT (86.5%), 5.5% were children, and 4.4% pregnant women. The most common effective dose of unnecessary radiation was 1 mSv or less (89.7% of all examinations). The highest effective doses were reported in CT (from under 1 mSv–20 mSv and above). The reasons for the adverse events were incorrect identification (32%), incorrect procedure, site or side (30%); and human errors or errors of knowledge (20%).ConclusionAdverse events occurred especially in CT examinations. It is important to collect and analyse incident data, assess the harmful events, learn from them and aim to reduce adverse events.Implications for practiceThis study emphasizes the need for radiological personnel to obtain evidence-based information on adverse events and focus on training to improve patient safety.     

Concussion reporting,knowledge and attitudes in Irish amateur gaelic games athletes

ObjectivesTo examine self-reported concussion history, knowledge and attitudes towards concussion reporting and education in Irish adult Gaelic games players.DesignCross-sectional survey.SettingData were collected using an online survey instrument.ParticipantsTwo hundred and sixteen adult Gaelic games athletes (106 male, 110 female).Main outcome measuresSelf-reported concussion history for the previous season, reporting history for participants’ most recent concussion, concussion knowledge, willingness to report future concussions in a variety of situations and desire for further concussion education.ResultsSeventy-three percent of participants suspected they had sustained a concussion in the past. Most (72.2%) informed someone of their most recent concussion, although two-thirds continued to play during their most recent concussion. Participants had a good overall understanding of concussion, although concussion knowledge score was not associated with safer behaviour following participants’ most recent concussion. While most agreed that concussion is a serious injury (95.8%), 46.8% would not report a concussion during important games.ConclusionsThe high proportion of participants playing following concussion and their reluctance to report concussions during important games is concerning. Interventions aimed at improving attitudes towards concussion reporting among athletes and other stakeholders are required to improve concussion management in amateur Gaelic games athletes.
