Abdominal stab wound injury in children: Do we need a different approach?

Background

Penetrating stab wounds in children are relatively rare and no clear recommendations for the optimal evaluation have been devised. An acceptable traditional approach to the patient with an abdominal stab wound who does not require urgent surgery is selective nonoperative management and serial exams. The use of routine computed tomography remains an actively utilized investigation for these patients at many institutions.

Dissemination of Misinformative and Biased Information about Prostate Cancer on YouTube

YouTube is a social media platform with more than 1 billion users and >600 000 videos about prostate cancer. Two small studies examined the quality of prostate cancer videos on YouTube, but did not use validated instruments, examine user interactions, or characterize the spread of misinformation. We performed the largest, most comprehensive examination of prostate cancer information on YouTube to date, including the first 150 videos on screening and treatment. We used the validated DISCERN quality criteria for consumer health information and the Patient Education Materials Assessment Tool, and compared results for user engagement. The videos in our sample had up to 1.3 million views (average 45 223) and the overall quality of information was moderate. More videos described benefits (75%) than harms (53%), and only 50% promoted shared decision-making as recommended in current guidelines. Only 54% of the videos defined medical terms and few provided summaries or references. There was a significant negative correlation between scientific quality and viewer engagement (views/month p = 0.004; thumbs up/views p = 0.015). The comments section underneath some videos contained advertising and peer-to-peer medical advice. A total of 115 videos (77%) contained potentially misinformative and/or biased content within the video or comments section, with a total reach of >6 million viewers.

Management of massive gastrointestinal haemorrhage

Acute gastrointestinal bleeding is a common medical emergency, accounting for approximately 85,000 admissions in the United Kingdom per annum. It is associated with significant morbidity and mortality. GI haemorrhage is commonly categorized according to source of blood loss; either upper GI (above the ligament of Treitz) or lower GI (below the ligament of Treitz). Rapid assessment, resuscitation and correction of coagulopathy should be undertaken to stabilize the haemodynamically compromised patient and definitive intervention should not be delayed. Clinicians may use of a range of treatment modalities, including endoscopic and interventional radiological techniques in order to get control of haemorrhage, which should be tailored to the site of bleeding and pathology. Where control is not achieved the clinician should consider either repeat intervention, use of alternative haemostatic techniques or different modalities to achieve haemostasis. Rarely is surgery the chosen treatment modality and surgical intervention should only be undertaken where all other measures to control haemorrhage have failed.     

Simulação de manejo de via aérea difícil para residentes: estudo comparativo prospectivo

Background and objectivesProcedural simulation training for difficult airway management offers acquisition opportunities. The hypothesis was that 3 hours of procedural simulation training for difficult airway management improves: acquisition, behavior, and patient outcomes as reported 6 months later.MethodsThis prospective comparative study took place in two medical universities. Second‐year residents of anesthesiology and intensive care from one region participated in 3 h procedural simulation (intervention group). No intervention was scheduled for their peers from the other region (control). Prior to simulation and 6 months later, residents filled‐out the same self‐assessment form collecting experience with different devices. The control group filled‐out the same forms simultaneously. The primary endpoint was the frequency of use of each difficult airway management device within groups at 6 months. Secondary endpoints included modifications of knowledge, skills, and patient outcomes with each device at 6 months. Intervention cost assessment was provided.Results44 residents were included in the intervention group and 16 in the control group. No significant difference was observed for the primary endpoint. In the intervention group, improvement of knowledge and skills was observed at 6 months for each device, and improvement of patient outcomes was observed with the use of malleable intubation stylet and Eschmann introducer. No such improvement was observed in the control group. Estimated intervention cost was 406€ per resident.ConclusionsA 3 h procedural simulation training for difficult airway management did not improve the frequency of use of devices at 6 months by residents. However, other positive effects suggest exploring the best ratio of time/acquisition efficiency with difficult airway management simulation.ClinicalTrials.gov IdentifierNCT02470195.

儿童系统性红斑狼疮与肾炎慢病管理及治疗进展

儿童系统性红斑狼疮（childhood-onset systemic lupus erythematosus，cSLE）是特指在18岁之前发病的系统性红斑狼疮。可累积全身多脏器、多系统，有多达60%的患儿会出现狼疮性肾炎（lupus nephritis，LN），其中19%的患儿进展为终末期肾病。感染和终末期肾病是导致发展中国家cSLE死亡的常见原因。由于疾病本身和治疗都会影响患儿的身心和生长发育，做好cSLE与LN的慢病管理对控制病情、提高长期生存率极为重要。本文总结了近年来国内外系统性红斑狼疮慢病管理的经验，并对cSLE与LN慢病管理和治疗进展进行综述，旨在提高治疗达标率，减少疾病复发及并发症的发生，使患儿获益。     

Distribution and Surgical Management of Visceral Ewing Sarcoma Among Children and Adolescents

IntroductionEwing sarcoma (EWS) is a highly malignant tumor of bone and soft tissue that occasionally arises from viscera. Visceral EWS (V-EWS) is challenging to manage given its varied organ distribution and often late-stage presentation. We aimed to characterize our institutional experience with V-EWS, focusing on its surgical management, and to compare V-EWS outcomes against those with osseous (O-EWS) and soft tissue EWS (ST-EWS).MethodsRetrospective review of all EWS patients ≤21 years presenting to a single institution between 2000 and 2022. Patient- and disease-specific characteristics were compared. Overall and relapse-free survival were estimated using Kaplan Meier methods and log-rank test.Results156 EWS patients were identified: 117 O-EWS, 20 ST-EWS, and 19 V-EWS. V-EWS arose in the kidney (n = 5), lung (n = 5), intestine (n = 2), esophagus (n = 1), liver (n = 1), pancreas (n = 1), adrenal gland (n = 1), vagina (n = 1), brain (n = 1), and spinal cord (n = 1). No significant demographic differences were detected between EWS groups. V-EWS was more frequently metastatic at presentation (63.2%; p = 0.005), yet no significant overall or relapse-free survival differences emerged between EWS groups, with similar follow-up intervals. While V-EWS required multiple unique operative strategies to gain primary control, no significant difference in treatment strategies appeared between groups. Surgery-only primary control was associated with improved overall and relapse-free survival in all groups.ConclusionsV-EWS presents unique management challenges in children and adolescents given its variable sites of origin. This large cohort is the first to describe the surgical management and outcomes of V-EWS, demonstrating more frequent metastatic presentation, while achieving similar survival across groups.Level of evidenceLevel 2 – Cohort Study.
