Comparison of 6 handheld ultrasound devices by point-of-care ultrasound experts: a cross-sectional study.

Background: Point-of-care ultrasound (POCUS) has emerged as an essential bedside tool for clinicians, but lack of access to ultrasound equipment has been a top barrier to POCUS use. Recently, several handheld ultrasound devices ("handhelds") have become available, and clinicians are seeking data to guide purchasing decisions. Few comparative studies of different handhelds have been done.

Sex and Gender in Lung Diseases and Sleep Disorders: A State-of-the-Art Review: Part 2.

There is now ample evidence that differences in sex and gender contribute to the incidence, susceptibility, presentation, diagnosis, and clinical course of many lung diseases. Some conditions are more prevalent in women, such as pulmonary arterial hypertension and sarcoidosis. Some life stages-such as pregnancy-are unique to women and can affect the onset and course of lung disease.

Midodrine in Liver Cirrhosis With Ascites: A Systematic Review and Meta-Analysis.

Ascites is the most common complication of liver cirrhosis. Midodrine is a vasoconstrictor that improves splanchnic and systemic hemodynamics, reduces ascites, and improves clinical outcomes. Here, we aimed to examine the role of midodrine in cirrhosis-related ascites.

Vasopressin versus norepinephrine as the first-line vasopressor in septic shock: A systematic review and meta-analysis.

Background And Aim: Norepinephrine is currently the first-line vasopressor for septic shock. We conducted this meta-analysis to examine the outcomes of adult patients with septic shock who received vasopressin instead of norepinephrine.

Methods: We selected studies in adults with septic shock that compared the outcomes of patients treated with vasopressin versus norepinephrine.

Sex and Gender in Lung Disease and Sleep Disorders: A State-of-the-Art Review.

The terms sex and gender often are used interchangeably, but have specific meaning when it comes to their effects on lung disease. Ample evidence is now available that sex and gender affect the incidence, susceptibility, presentation, diagnosis, and severity of many lung diseases. Some conditions are more prevalent in women, such as asthma.

Outcomes of critically ill solid organ transplant patients with COVID-19 in the United States.

National data on patient characteristics, treatment, and outcomes of critically ill coronavirus disease 2019 (COVID-19) solid organ transplant (SOT) patients are limited. We analyzed data from a multicenter cohort study of adults with laboratory-confirmed COVID-19 admitted to intensive care units (ICUs) at 68 hospitals across the United States from March 4 to May 8, 2020. From 4153 patients, we created a propensity score matched cohort of 386 patients, including 98 SOT patients and 288 non-SOT patients.

Prognostication via early computed tomography head in patients treated with targeted temperature management after cardiac arrest.

Background: We evaluated computed tomography head (CTH) imaging obtained prior to targeted temperature management (TTM) in patients after cardiac arrest, and its role in prognostication.

Methods: In this retrospective cohort study in a tertiary-care hospital, 341 adults presenting with out-of-hospital cardiac arrest received a CTH prior to TTM. Associations between outcomes and neuroimaging variables were evaluated with Chi-square analysis for significant associations that yielded a composite neuroimaging score-Tennessee Early Neuroimaging Score (TENS).

Endobronchial Lesions in Patients Presenting with Hemoptysis.

Objectives: The aim of this study was to determine the incidence of endobronchial lesions in patients presenting with hemoptysis. We also aimed to characterize features that would predict whether bronchoscopy would be useful.

Methods: A retrospective chart review was conducted on 185 consecutive patients who presented with hemoptysis from January 1, 2006 to December 31, 2015 at Methodist Le Bonheur Healthcare-affiliated hospitals in Memphis, Tennessee.

Atrio-Esophageal Fistula: A Case Series and Literature Review.

BACKGROUND Percutaneous catheter radiofrequency ablation (RFA) and cryoablation of the left atrium and pulmonary vein ostia have become successful therapeutic modalities in the management of atrial fibrillation. Atrio-esophageal fistula is a rare complication. Awareness of complication risk is imperative because without prompt diagnosis and urgent surgical intervention, the outcome is often fatal.

Therapeutic plasmapheresis for hypertriglyceridemia-associated acute pancreatitis: case series and review of the literature.

Background: Severe hypertriglyceridemia (HTG) is the third leading cause of acute pancreatitis (AP) in the United States. The current standard of care includes management of HTG using pharmacological therapy. More recently, plasmapheresis has been proposed as a therapeutic tool for decreasing triglyceride (TG) levels, especially in critically ill patients.

Chronic Granulomatous Disease Presenting as Aspergillus Fumigatus Pneumonia in a Previously Healthy Young Woman.

BACKGROUND Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life.

Pembrolizumab-induced myasthenia gravis: A fatal case report.

Purpose Pembrolizumab, a monoclonal antibody which inhibits the programmed cell death 1 receptor, has been shown to efficaciously enhance pre-existing immune responses to malignancies. However, safety concerns must also be considered as pembrolizumab use has been associated with several life-threatening immune-related adverse events (irAEs). We report a fatal case of pembrolizumab-induced myasthenia gravis in a patient with no prior myasthenia gravis history.

Role of Transbronchial Needle Aspiration (Conventional and EBUS Guided) in the Diagnosis of Histoplasmosis in Patients Presenting with Mediastinal Lymphadenopathy.

Objectives: The superior performance of endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) in the diagnosis and staging of malignancy has been demonstrated, with some investigators suggesting the same for sarcoidosis. The role of EBUS-TBNA in the diagnosis of histoplasmosis is not clear, however. In this study we estimate the diagnostic yield of conventional TBNA (cTBNA) and EBUS-TBNA for the diagnosis of histoplasmosis in patients with mediastinal lymphadenopathy.

Metastatic Squamous Cell Carcinoma of the Pleura: A Rare Complication of Hidradenitis Suppurativa.

BACKGROUND Squamous cell carcinoma (SCC), also known as Marjolin ulcer, is a rare complication of hidradenitis suppurativa (HS). Metastatic SCC from HS typically involves the axial skeleton or abdominopelvic viscera. Metastatic disease to the lungs is a rare phenomenon with only three reported cases of lung parenchyma.

Vitamin D Supplementation: Not So Simple in Sarcoidosis.

Introduction: Americans are increasingly receiving vitamin D supplementation, often based on low-measured 25-hydroxy-vitamin D (25-OH-vit D). In sarcoidosis, there is often increased metabolism of 25-OH-vit D to 1,25-dihydroxy-vitamin D (1,25-OH-vit D), so 25-OH-vit D may remain low, despite high levels of 1,25-OH-vit D. In such cases, vitamin D supplementation may lead to hypercalcemia.

Concurrent Myelomatous Pleural Effusion and Extramedullary Mediastinal Involvement as an Initial Manifestation of Multiple Myeloma.

BACKGROUND Myelomatous pleural effusion (MPE) is a rare occurrence in patients with multiple myeloma (MM). Fewer than 20 cases of MPE have been reported as an initial manifestation of MM. Extramedullary plasmacytoma (EMP) occurs in fewer than 5% patients with MM, and mediastinal EMP is even rarer, with only about 80 cases reported in the literature.

Pleural Small Cell Lung Carcinoma: An Unusual Culprit in Pleural Effusion.

Background: Small cell lung carcinoma (SCLC) usually presents as lung or mediastinal lesions. It is very rare for SCLC to present primarily as an isolated pleural effusion with no lung or mediastinal lesions.

Case Report: We report the case of a 77-year-old white male with a 60-pack year history of smoking, chronic obstructive pulmonary disease (stage IV), and asbestos exposure who presented with shortness of breath and left lateral chest pain for 7 days.

Solitary Fibrous Tumor of the Pleura: A Rare Cause of Pleural Mass.

Background: A solitary fibrous tumor of the pleura is a rare but usually benign mesenchymal tumor arising from the pleura. Patients are often asymptomatic, resulting in the majority of tumors being detected incidentally on chest imaging. We present a case of a large solitary pleural tumor and review the typical radiographic and pathologic findings associated with this finding.

Wait!!! No Steroids for this Asthma….

Background: Strongyloides stercoralis (SS) is a parasite seen in certain parts of the USA and in people from other endemic areas. In these patients steroids might precipitate or exacerbate asthma. Apart from worsening of asthma, serious complications like hyperinfection syndrome and even death can occur in these patients if treated with steroids.
