RESUMEN
OBJECTIVES: Management of refractory cancer-associated pain can be particularly challenging. Regional anesthesia is an alternative modality to treat acute and chronic refractory pain. Intrathecal (IT) drug delivery of opioids and other adjuncts has been used to treat refractory cancer-associated pain. This method has been shown to be relatively safe and effective, often associated with fewer systemic side effects when compared to oral or IV opioid administration. While intrathecal drug delivery systems (IDDS) are regularly used in the adult cancer population for the treatment of refractory, chronic pain, there is limited evidence of similar use in the pediatric setting. MATERIALS AND METHODS: We performed a systematic review using conventional Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology to identify studies reporting IT drug delivery for the treatment of pediatric cancer-related pain. The primary outcome was satisfaction with analgesia categorized as "satisfactory" or "unsatisfactory." Functional benefits, previous systemic pharmaceutical interventions, previous non-IT regional interventions, indication for IT drug delivery, IT drugs used, and method of delivery were collected. RESULTS: A total of 11 studies were identified, describing 16 patients with cancer-related pain treated with IT drug delivery. The average age of the cohort was 12.25 years, with ages ranging from 3 to 19 years. Most patients were adolescent (10/16). All patients had cancer diagnoses, with most patients suffering from solid tumor pain (14/16). Nearly all patients achieved satisfactory analgesia through IT drug delivery (15/16) and most reported functional benefits in addition to analgesia (13/16). Majority received IT drugs via external catheters (9/16). One severe complication of respiratory depression was reported, which resolved following naloxone administration. CONCLUSIONS: There exist children with cancer whose pain is refractory to the standard approaches and may benefit from IT drug delivery. The existing data, although limited and of low tier evidence, suggest that IT drug delivery has been effective in the pediatric cancer population.

OBJECTIVES: Three-dimensional (3D) transesophageal echocardiography (TEE) has been shown to be more accurate than 2D TEE for the evaluation of the left ventricular outflow tract area. The aim of the present study was to compare the agreement of 3D echocardiography-derived cardiac output (CO) with thermodilution-derived CO (TDCO) before and after cardiopulmonary bypass (CPB). DESIGN: This was a prospective observational study of patients who underwent cardiac surgery between 2016 and 2018. SETTING: Weill Cornell Medicine, a single large academic medical center. PARTICIPANTS: The study comprised 78 patients undergoing elective cardiac surgery. INTERVENTIONS: CPB, TEE, pulmonary artery catheter, and elective cardiac surgery. MEASUREMENTS AND MAIN RESULTS: Two-dimensional CO, 3D CO-diameter, and 3D CO-area values pre-CPB were strongly correlated with one another both pre-CPB and post-CPB. The 3D CO-diameter and the 3D CO-area were mildly correlated, with TDCO measurements pre-CPB (râ¯=â¯0.46 and 0.39, respectively) and post-CBP (râ¯=â¯0.43 and 0.47, respectively). Pre-CPB 3D CO-diameter had the most agreement with TDCO in terms of bias (-0.13 L/min); however, the limits of agreement (LOA) were wide (-2.2- to- 2.45 L/min). Post-CPB, 3D CO-diameter had the most agreement with TDCO in terms of bias (0.41) but with wide LOA (-3.29 to 2.47). All pre-CPB echocardiography-derived CO (2D CO, 3D CO-diameter, 3D CO-area) had more agreement with TDCO than did post-CPB measurements. CONCLUSIONS: Three-dimensional CO measurements were only modestly correlated with pulmonary artery catheter-derived CO pre-bypass and post-bypass. Despite low bias, the wide LOA from 2D CO, 3D CO-diameter, and 3D-area compared with TDCO suggested that the 2 methods are not interchangeable.

Elevated pernio incidence was observed during the COVID-19 pandemic. This prospective study enrolled subjects with pandemic-associated pernio in Wisconsin and Switzerland. Because pernio is a cutaneous manifestation of the interferonopathies, and type I interferon (IFN-I) immunity is critical to COVID-19 recovery, we tested the hypothesis that severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-mediated IFN-I signaling might underlie some pernio cases. Tissue-level IFN-I activity and plasmacytoid dendritic cell infiltrates were demonstrated in 100% of the Wisconsin cases. Across both cohorts, sparse SARS-CoV-2 RNA was captured in 25% (6/22) of biopsies, all with high inflammation. Affected patients lacked adaptive immunity to SARS-CoV-2. A hamster model of intranasal SARS-CoV-2 infection was used as a proof-of-principle experiment: RNA was detected in lungs and toes with IFN-I activity at both the sites, while replicating virus was found only in the lung. These data support a viral trigger for some pernio cases, where sustained local IFN-I activity can be triggered in the absence of seroconversion.
RESUMEN
We have previously published a novel transfusion medicine curriculum for first-year anesthesiology residents, making available open access learning materials. We now present a curriculum iteration, by incorporating resident feedback and developing an additional "capstone" session for use at the end of the rotation that integrates several learning points into a practical problem-based simulation. This iteration of the curriculum was piloted with the 2019-2020 PGY-1 anesthesiology residents of the University of Wisconsin Hospitals and Clinics. Pre-course and post-course surveys, which assessed trainee understanding of course topics, were used to subjectively evaluate the usefulness of the curriculum. Results of the surveys demonstrated post-test mean scores were significantly increased when compared with the equivalent pre-course questions. This suggests the piloted curriculum iteration serves as a useful tool for resident learning. As an adjunct to our previous existing materials, in the spirit of open-access education, we share this additional curriculum material, consisting of four patient cases with 16 questions that can be used immediately for teaching purposes.
RESUMEN
Background: Pilonidal disease is a chronic inflammatory skin disorder typically located in the gluteal cleft. Treatment varies from antibiotic therapy to extensive surgical resection and reconstruction; however, complications and recurrence are common. To understand risk factors, outcomes, and costs associated with various treatments, we performed a retrospective chart review of all patients treated for pilonidal disease at a single health care system from 2008 to 2018. Methods: Patients with an ICD diagnosis code associated with pilonidal disease were identified. Charts were reviewed for demographic, clinical, and cost information related to pilonidal disease encounters. Data were analyzed for risk of recurrence by Cox proportional hazards regression and economic burden by Wilcoxon signed-rank test. Results: During the study time frame, 513 patients were diagnosed with pilonidal disease. Primary treatment included 108 patients (21%) with wide excision, 167 (32%) with antibiotics alone, 79 (15%) with incision and drainage, and 109 (21%) with incision and drainage plus antibiotics. The rate of recurrence following antibiotic therapy, incision and drainage, or wide excision was 36.7%, 35.9%, and 21.3%, respectively. Sex, body mass index, obesity, or hidradenitis suppurativa was not associated with recurrence; however, smokers who underwent incision and drainage had a higher risk of recurrence (Pâ¯<â¯.0001). The median cost of each primary treatment was $3,093 for excision, $607 for incision and drainage, $281 antibiotics alone, and $686 for incision and drainage plus antibiotics. Conclusion: Pilonidal disease presents with a high degree of heterogeneity and is often managed primarily with antibiotics, incision and drainage, or surgical excision. Risk of recurrence was less in patients who underwent wide excision; however, these patients had higher overall cost compared to patients that had nonoperative management. Level of evidence: Level III.
