Hypoxemic Respiratory Failure Due to Alveolar Pulmonary Sarcoidosis Following COVID-19 Infection.

Pulmonary sarcoidosis is typically recognized as an interstitial lung disease with an infrequent occurrence of alveolar filling or acinar pattern. This rare form of alveolar sarcoidosis is known to have a rapid progression. Several case reports showed the development/worsening of sarcoidosis after COVID-19 infection.

Prognosis in Hispanic patient population with pulmonary arterial hypertension: An application of common risk stratification models.

Pulmonary arterial hypertension (PAH) is a cardiovascular disease with high mortality rate. Current guidelines propose initiation and escalation of PAH-targeted treatment based on a goal-directed approach targeting hemodynamic, functional, and biochemical variables. This approach has been successfully validated in large Caucasian cohorts.

Paraneoplastic Hypereosinophilia in Poorly Differentiated Adenocarcinoma of the Lung.

It is well-documented that lung and bronchus cancers are the leading cause of cancer death in the United States in both male and female patients, with lung adenocarcinoma accounting for the highest prevalence of lung cancers. Significant eosinophilia in the setting of lung adenocarcinoma has been documented in a few reports, being described as a rare paraneoplastic syndrome. We report on an 81-year-old female with hypereosinophilia-associated lung adenocarcinoma.

Bilateral pneumatoceles resulting in spontaneous bilateral pneumothoraces and secondary infection in a previously healthy man with COVID-19.

An acute COVID-19 infection can result in cystic lung changes that have a unique presentation and are inherently difficult to manage with or without preexisting conditions. Even though reportedly very few COVID-19 patients develop secondary bacterial infections due to unclear mechanisms, a postviral sequela with typical and atypical organisms can prolong the course of lung damage. The long-term effects of COVID-19 lung damage are still unclear, as the morbidity of the disease process is yet to be fully understood.

Pediatric Living Lung Donor Transplant Candidates: Psychiatric Status of Utilized and Non-Utilized Donors.

Living donor lung (lobar) transplantation has greatly decreased in the past decade due to the success of the lung allocation score (LAS) system, instituted in 2005 by the Organ Procurement and Transplantation Network (OPTN). Between 1993 and 2006, 460 living lung donor transplants were performed in the United States with 369 donations occurring at the University of Southern California and Washington University in St. Louis.

Anti-glomerular basement membrane (Goodpasture) disease exacerbated by invasive pulmonary aspergillosis.

Prior reports have associated the unusual presentations of anti-glomerular basement membrane (anti-GBM) disease and pulmonary aspergillosis in an immunocompetent host. We present the case of a previously healthy 24-year-old man who presented with symptoms of hemoptysis, cough, and dyspnea. His environmental risk factors included tobacco use (smoking), hydrocarbon exposure, and an unidentified mold present in his home.

Predictors and outcomes of acute respiratory failure in hospitalised patients with acute pancreatitis.

Background And Aim: Acute pancreatitis (AP) is associated with organ failures and systemic complications, most commonly acute respiratory failure (ARF) and acute kidney injury. So far, no studies have analysed the predictors and hospitalisation outcomes, of patients with AP who developed ARF. The aim of this study was to measure the prevalence of ARF in AP and to determine the clinical predictors for ARF and mortality in AP.

Fatal pulmonary tumor thrombotic microangiopathy caused by undiagnosed metastatic gastric adenocarcinoma.

Pulmonary tumor thrombotic microangiopathy (PTTM) is a rare cause of rapidly progressive dyspnea in a background of metastatic cancer. Gastric adenocarcinoma is the neoplasm most frequently associated with PTTM. Unfortunately, PTTM is difficult to identify clinically and is most commonly a postmortem diagnosis.

Hyperbaric oxygen: a useful adjunct for purpura fulminans: case report and review of the literature.

Introduction: We report a case of a previously healthy adult with flulike symptoms who precipitously declined due to pneumococcal sepsis complicated by disseminated intravascular coagulation (DIC) and purpura fulminans (PF). After one week of care, including ventilation support and hemodialysis, the patient was stable enough for hyperbaric oxygen (HBO2) in an attempt to salvage his threatened extremities. HBO2 resulted in reduction of ischemic tissue and demarcation of blackened tissue to the distal digits.

Development and validation of a risk calculator for predicting postoperative pneumonia.

Objective: To identify preoperative factors associated with an increased risk of postoperative pneumonia and subsequently develop and validate a risk calculator.

Patients And Methods: The American College of Surgeons' National Surgical Quality Improvement Program, a multicenter, prospective data set (2007-2008) was used. Univariate and multivariate logistic regression analyses were performed.

Impact of COPD on postoperative outcomes: results from a national database.

Background: Although COPD affects large sections of the population, its effects on postoperative outcomes have not been rigorously studied. The objectives of this study were to describe the prevalence of COPD in patients undergoing surgery and to analyze the associations between COPD and postoperative morbidity, mortality, and hospital length of stay.

Methods: Patients with COPD who underwent surgery were identified from the National Surgical Quality Improvement Program database (2007-2008).

A systematic review of the cardiovascular risk of inhaled anticholinergics in patients with COPD.

The long-term use of inhaled anticholinergic agents has recently been suggested to be associated with an excess risk of adverse cardiovascular (CV) outcomes in patients with COPD. We identified 15 published studies that reported on the association between long-term inhaled anticholinergic use and adverse CV outcomes. Only 3 of the studies were adequately designed randomized controlled trials (RCTs).

Differences in treatment and in outcomes between idiopathic and secondary forms of organizing pneumonia.

Organizing pneumonia is a major reparative response of the lung tissue to an acute injury and is a pathological hallmark of an entity called bronchiolitis obliterans organizing pneumonia (BOOP). It can be idiopathic and called cryptogenic organizing pneumonia (COP) or be secondary to various conditions such as infections, drugs, connective tissue disorders, and radiation. Fifty-seven patients with pathologically confirmed BOOP were identified and were classified as having either COP or secondary BOOP on the basis of whether there was an identifiable cause.
