Management of Pericardial Effusion in Patients With Solid Tumor: An Algorithmic, Multidisciplinary Approach Results in Reduced Mortality After Paradoxical Hemodynamic Instability.

OBJECTIVE: This study compared outcomes in patients with solid tumor treated for pericardial effusion with surgical drainage versus interventional radiology (IR) percutaneous drainage and compared incidence of paradoxical hemodynamic instability (PHI) between cohorts. BACKGROUND: Patients with advanced-stage solid malignancies may develop large pericardial effusions requiring intervention. PHI is a fatal and underreported complication that occurs following pericardial effusion drainage. METHODS: Clinical characteristics and outcomes were compared between patients with solid tumors who underwent s urgical drainage or IR percutaneous drainage for pericardial effusion from 2010 to 2020. RESULTS: Among 447 patients, 243 were treated with surgical drainage, of which 27 (11%) developed PHI, compared with 7 of 204 patients (3%) who were treated with IR percutaneous drainage ( P =0.002); overall incidence of PHI decreased during the study period. Rates of reintervention (30-day: 1% vs 4%; 90-day: 4% vs 6%, P =0.7) and mortality (30-day: 21% vs 17%, P =0.3; 90-day: 39% vs 37%, P =0.7) were not different between patients treated with surgical drainage and IR percutaneous drainage. For both interventions, OS was shorter among patients with PHI than among patients without PHI (surgical drainage, median [95% confidence interval] OS, 0.89 mo [0.33-2.1] vs 6.5 mo [5.0-8.9], P <0.001; IR percutaneous drainage, 3.7 mo [0.23-6.8] vs 5.0 mo [4.0-8.1], P =0.044). CONCLUSIONS: With a coordinated multidisciplinary approach focusing on prompt clinical and echocardiographic evaluation, triage with bias toward IR percutaneous drainage than surgical drainage and postintervention intensive care resulted in lower incidence of PHI and improved outcomes.

Essential Review of Oncological Emergencies.

Innovations in oncology have expanded treatment eligibility, leading to a rise in cancer patients requiring critical care. This necessitates that all critical care clinicians possess a fundamental knowledge of prevalent oncological conditions and identify emergent scenarios requiring immediate action. This article will explore key oncological complications and their management approaches.

Caring for patients with life-threatening hemoptysis.

ABSTRACT: Life-threatening hemoptysis (formerly called massive hemoptysis), though relatively uncommon, imposes significant mortality risks. This article discusses the etiology, clinical presentation, assessment, treatment, and nursing interventions to promote effective clinical management of patients with this condition.

Pseudohyponatremia: A Concise Guide to Diagnosis and Management in Clinical Practice.

Pseudo-hyponatremia is an uncommon laboratory finding that can lead to serious morbidity and mortality if not recognized abruptly. Often linked to conditions like hyperlipidemia or hyperproteinemia, pseudohyponatremia can mislead clinicians and result in misdiagnosis. We discuss this through two real-world case studies, explaining how it develops and how to diagnose it accurately. It's paramount that clinicians recognize and properly differentiate pseudohyponatremia from true hyponatremia to prevent wrong treatments. We stress the need to address the root causes in order to provide the optimal patient care.

PD-1 inhibitors for cutaneous squamous cell carcinoma: A meta-analysis.

PD-1 inhibitors are immunotherapeutic agents used in the treatment of advanced cutaneous squamous cell carcinoma (cSCC). This study aimed to determine the pooled objective response and disease control rates of patients with advanced cSCC treated with PD-1 inhibitors. Pubmed, Cochrane Library and EMBASE databases were searched up to 1 January 2021 to include eligible articles. Objective response rate (ORR) and disease control rate (DCR) were pooled and analysed. Subgroup analysis of the odds ratio (OR) for ORR for patients by PD-L1 tumour proportion score (TPS) was performed. Seven articles including a total of 453 patients were identified and included. Pooled estimate of ORR was 44% (95% CI: 39-49%, I2 = 23.7%) and of DCR was 66% (95% CI: 57-74%, I2 = 68.2%). Pooled odds ratio of ORR for patients by PD-L1 TPS was 2.81 (95% CI: 1.22-6.51, I2 = 0.0%). These results were derived from single-arm studies, some of which were retrospective. No head-to-head trials comparing PD-1 inhibitors have been reported. We present aggregate estimates of ORR and DCR for patients with advanced cSCC treated with PD-1 inhibitors, as well as subgroup analysis for ORR for patients by PD-L1 TPS.

Intracardiac Thrombus in Transit Detected by Point-of-Care Ultrasound.

Pulmonary embolism (PE) is a condition with a high rate of morbidity and mortality if it is not recognized and treated in a timely fashion. Point-of-care ultrasound (POCUS) is a useful tool that can help clinicians make prompt diagnosis. We present a case where we diagnosed massive PE through visualizing an intracardiac thrombus in transit, and we highlight some important ultrasonographic features.

A Tale of Two Pulmonary Artery Catheters.

Innovative catheter-based therapies are increasingly being used for the treatment of patients with submassive pulmonary embolism. These patients may be monitored in the intensive care unit following insertion of specialized pulmonary artery catheters. However, the infusion catheters utilized in catheter-based therapies differ greatly from traditional pulmonary artery catheters designed for hemodynamic monitoring. As such, the critical care team will have to be familiar with the monitoring and management of these novel catheters. Important distinctions between the catheters are illustrated using a clinical case report.

An Uncommon Cause of Chest Pain: Hypertriglyceridemia-Induced Pancreatitis.

Chest pain is a common and high-risk chief complaint in the emergency department. There is an array of cardiac and non-cardiac-related conditions that could lead to this symptom. It is important for the clinician to have a broad perspective when treating patients complaining of chest pain so that dangerous and potentially life-threatening conditions are not overlooked. Here, we present one such cause of chest pain that can be detrimental if the clinician fails to correctly identify the underlying condition. A brief review of hypertriglyceridemia-induced acute pancreatitis is provided, and challenges faced by the treatment team are discussed.

Correlation of well-being during dermatology residency with future career plans.

Burnout is increasingly common in the medical field. In dermatology, burnout is attributed to high patient volume and excessive time spent on electronic medical record system activities. The shortage of the dermatology workforce in academic medicine is well-known. Studies have yet to examine the relationship between well-being during dermatology residency and the pursuit of academia. OBJECTIVE: To assess the well-being of dermatology residents in the United States, identify barriers/enablers to well-being, and determine the implications of these measures. METHODS: A cross-sectional survey was distributed to program coordinators of 136 accredited dermatology programs with instructions to forward to their current dermatology residents. Residents provided self-reported ratings on validated scales measuring burnout, depression, anxiety, fatigue, and quality of life. Descriptive statistics and correlations were examined. RESULTS: Residents with higher levels of burnout reported they were significantly less likely to pursue academia, full-time work, clinical research, and fellowships after residency. The results showed opposite effects for residents with higher qualities of life. CONCLUSIONS: This study showed that resident well-being can have a significant impact on residents' future career plans, including pursuing academic dermatology, clinical research, and fellowship. Addressing burnout in the field of dermatology offers an opportunity to increase the academic dermatology workforce.

The RSNA Pediatric Bone Age Machine Learning Challenge.

Purpose The Radiological Society of North America (RSNA) Pediatric Bone Age Machine Learning Challenge was created to show an application of machine learning (ML) and artificial intelligence (AI) in medical imaging, promote collaboration to catalyze AI model creation, and identify innovators in medical imaging. Materials and Methods The goal of this challenge was to solicit individuals and teams to create an algorithm or model using ML techniques that would accurately determine skeletal age in a curated data set of pediatric hand radiographs. The primary evaluation measure was the mean absolute distance (MAD) in months, which was calculated as the mean of the absolute values of the difference between the model estimates and those of the reference standard, bone age. Results A data set consisting of 14 236 hand radiographs (12 611 training set, 1425 validation set, 200 test set) was made available to registered challenge participants. A total of 260 individuals or teams registered on the Challenge website. A total of 105 submissions were uploaded from 48 unique users during the training, validation, and test phases. Almost all methods used deep neural network techniques based on one or more convolutional neural networks (CNNs). The best five results based on MAD were 4.2, 4.4, 4.4, 4.5, and 4.5 months, respectively. Conclusion The RSNA Pediatric Bone Age Machine Learning Challenge showed how a coordinated approach to solving a medical imaging problem can be successfully conducted. Future ML challenges will catalyze collaboration and development of ML tools and methods that can potentially improve diagnostic accuracy and patient care. © RSNA, 2018 Online supplemental material is available for this article.

Review of systemic agents in the treatment of advanced cutaneous squamous cell carcinoma.

Advanced cutaneous squamous cell carcinoma (cSCC) accounts for only 5% of all cases of cSCC but up to 60% of disease related deaths. Historically, this disease has lacked effective treatment options due to a combination of poor response rate, poor response durability and significant treatment-associated morbidity. Autumn of 2018 marked the first time ever that an agent received US FDA approval for advanced cSCC and the future is looking much brighter for this previously neglected patient population. The purpose of this article is to review the various systemic treatment options for advanced cSCC moving from the past to the present, highlighting their relative merits and shortcomings, and to briefly speculate on future developments in the field of advanced cSCC.

Emerging Nonsurgical Therapies for Locally Advanced and Metastatic Nonmelanoma Skin Cancer.

BACKGROUND: Locally advanced and metastatic nonmelanoma skin cancer (NMSC) not amenable to surgical resection requires a different approach to therapy. OBJECTIVE: To review the efficacy and adverse effects of emerging treatment options for locally advanced and metastatic NMSC. MATERIALS AND METHODS: A comprehensive search on PubMed was conducted to identify relevant literature investigating the role of program cell death 1 (PD-1) inhibitor, cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) inhibitor, epidermal growth factor receptor (EGFR) inhibitor, and Hedgehog pathway inhibitors in the treatment of NMSC. RESULTS: PD-1 inhibitor and CTLA-4 inhibitor have shown promising efficacy with tolerable side-effect profiles in the treatment of NMSC, although the number of cases reported is limited. Currently, 3 larger-scale clinical trials are investigating PD-1 inhibitor therapy for NMSC. Similarly, EGFR inhibitor demonstrated marginal success in unresectable cutaneous squamous cell carcinomas. Hedgehog pathway inhibitors were approved by the US FDA for treatment of locally advanced and metastatic basal cell carcinomas and have shown favorable efficacy. Common adverse effects included muscle spasm, alopecia, and dysgeusia. CONCLUSION: Systemic therapies including PD-1 inhibitors and CTLA-4 inhibitors have demonstrated early promising results for difficult-to-treat NMSC. Future studies are necessary to optimize treatment outcome.

Spurious Laboratory Values in Patients With Leukocytosis.

Physiological derangements such as hypoxemia and hyperkalemia are medical emergencies that warrant prompt interventions to prevent further patient clinical deterioration. However, in patients with myeloproliferative diseases or malignancies that result in extreme leukocytosis, hypoxemia and hyperkalemia demonstrated in laboratory results could be deceiving due to in vitro reactions and may not reflect actual patient condition. Clinicians have to be familiar with these phenomena so as to not cause harm by treating these spurious laboratory values.

Surgical site identification with personal digital device: A prospective pilot study.

BACKGROUND: Various means to facilit ate accurate biopsy site identification have been proposed. OBJECTIVE: To determine the accuracy of biopsy site identification by using photographs taken with a patient's digital device by a dermatologist versus professional medical photography. METHODS: Photographs of circled biopsy sites were taken with personal digital devices by the principal investigator (PI). Another set of photographs was taken by a professional photographer. Secondary photographs were taken of the biopsy site location pointed to by the staff and PI on the basis of the personal digital device image and professional medical photography, respectively. On the basis of secondary photographs, 2 independent dermatologists determined whether the skin biopsy locations pointed out by the staff were consistent with the ones pointed out by PI. RESULTS: Per dermatologist A, the staff correctly identified all 53 biopsy sites. Per dermatologist B, the staff were correct on 51 of 53 observations. Dermatologist C, the final arbiter, concurred with dermatologist A on the 2 cases in which dermatologist B was not certain of the location of the biopsy site. LIMITATIONS: The mean interval from initial biopsy to reidentification of the site was 36.2 days. CONCLUSION: Utilizing patients' personal digital devices is a cost-effective, Health Insurance Portability and Accountability Act-compliant, and readily available means to identify skin biopsy sites.

Treatment of advanced basal cell carcinoma with sonidegib: perspective from the 30-month update of the BOLT trial.

Sonidegib, a hedgehog pathway inhibitor, was approved by the US FDA for the treatment of locally advanced basal cell carcinoma which cannot be readily treated with surgery or radiotherapy. The pharmacology and pharmacokinetics of sonidegib will be discussed in this review. Additionally, an in-depth analysis of the BOLT trial and data from the 30-month update will be included. This will serve as an update to a previously published article which reported the 12-month update of the BOLT trial.

Point-of-Care Ultrasonography in Emergency and Critical Care Medicine.

To stabilize critically ill patients, emergency and critical care medicine providers often require rapid diagnosis and intervention. The demand for a safe, timely diagnostic device, alongside technological innovation, led to the advent of point-of-care ultrasonography (POCUS). POCUS allows the provider to gain invaluable clinical information with a high level of accuracy, leading to better clinical decision-making and improvements in patient safety. We have outlined the history of POCUS adaptation in emergency and critical care medicine and various clinical applications of POCUS described in literature.

Leukocytoclastic vasculitis with late-onset Henoch-Schönlein purpura after trifluridine/tipiracil treatment.

Trifluridine/tipiracil has been approved for the treatment of refractory metastatic colorectal cancer. Adverse effects of this drug combination include leukopenia, neutropenia, fatigue, diarrhea, and vomiting. We present a case of trifluridine/tipiracil-induced leukocytoclastic vasculitis (LCV) with late-onset Henoch-Schönlein purpura (HSP) in a 42-year-old man with metastatic appendiceal cancer. The patient's biopsy-proven LCV developed one month after he began trifluridine/tipiracil treatment and resolved after discontinuation of the drug. He presented to the emergency department two months after the appearance of his LCV with shortness of breath, elevated blood pressure, elevated creatinine, hematuria, and proteinuria. A kidney biopsy was performed and the presence of IgA deposits and cellular crescents indicated rapidly progressive glomerulonephritis secondary to Henoch-Schönlein purpura (HSP). Neither LCV nor HSP have been reported as adverse effects of trifluridine/tipiracil treatment. Malignancy as a cause of our patient's HSP is another possibility. The delay between our patient's skin findings and acute renal failure indicates that suspected HSP should be monitored by urinalysis for a period of time owing to the risk of life-threatening renal disease.
