Pleural effusions appearing within the first 30 postoperative days following coronary artery bypass grafting (CABG) are classified as early and believed to be directly related to the surgery. The characteristics of such effusions are well-described. Orthotopic heart transplantation is also known to be complicated by pleural effusions; however, their characteristics have not been systematically reported. We assessed the features of early postoperative pleural effusions after heart transplantation and compared them to those of early effusions following CABG.

Silicosis is typically an indolent lung disease caused by longstanding occupational exposure to respirable crystalline silica, classically in professions such as sandblasting and mining. An increasingly popular industry that has earned particular interest because of its association with silicosis is customization and installation of artificial stone countertops for domestic applications. In addition to causing a spike in cases of chronic and accelerated silicosis, both quite familiar to respiratory clinicians, outbreaks of artificial stone silicosis have brought to the fore a historically rare entity known as acute silicosis, or silicoproteinosis, a more rapid presentation of the disease. Failure to suspect this uncommon condition can lead to diagnostic confusion and therefore ineffective treatment as was true initially of the patient we describe herein. The case description is followed by a clinical, radiological, and pathological overview of acute artificial stone silicosis (or silicoproteinosis), which is an emerging pneumoconiosis with sparse coverage in the literature to date. This case also adds to the few existing reports on the use of therapeutic whole lung lavage for silicoproteinosis. [ABSTRACT FROM AUTHOR]

The article describes two cases of ventricular shunt complications in pulmonary and critical care medicine. The first patient is a 29-year-old man who developed subcutaneous emphysema from the neck to the scrotum and bowel perforation as complication of ventriculoperitoneal shunts (VPS). The second patient is a 56-year-old woman who developed bronchospasm and central venous thrombosis with collateralization.

Sphingolipids are a distinct class of lipid molecules widely found in nature, principally as cell membrane constituents. After initial uncertainty about their function, sphingolipids have been increasingly recognised to be metabolically active entities involved in many biological processes, including the control of inflammation. Their role as mediators of inflammation may have significant implications for a range of lung diseases in which inflammation is a central element of pathogenesis. Chronic obstructive pulmonary disease (COPD), a highly prevalent and morbid condition predominantly affecting cigarette smokers, is a prime example of a respiratory illness with an inflammatory component. Understandably, sphingolipids have received growing attention for their increasingly demonstrated role in the pathophysiology of COPD. The present review aims to be among the first to focus exclusively on the connection between sphingolipids and lung inflammation in COPD, providing the reader with a clinically oriented synopsis of this intriguing association.

Background: The aging of the US population has been associated with an increase in intensive care unit (ICU) utilization and correspondingly, invasive mechanical ventilation (IMV) among the oldest-old (age ≥80 years). While previous studies have examined ICU and IMV outcomes in the elderly, very few have focused on patient-centered outcomes, specifically home return, in the oldest-old. We investigated the rate of immediate home return following IMV in the medical ICU in previously home-dwelling oldest-old patients relative to that of a comparison group of 50-70-year olds. Methods: Data were extracted retrospectively from patient records at Elmhurst Hospital Center in Elmhurst, NY, USA, encompassing the period from January 2009 to May 2014 and Jacobi Medical Center in the Bronx, NY, USA, from January 2010 to March 2014. Medical ICU admissions within those date ranges were screened for possible inclusion into one of two study groups based on age: ≥80 years old and 50-70 years old. The primary end point was hospital discharge: home return versus no home return (death or nonhome discharge). Cox proportional hazards' regression models were used to estimate crude and multivariable-adjusted hazard ratios (HRs) with 95% confidence intervals (CIs) for failure to return home. Results: A total of 375 patients were included in the analysis: 279 (74%) patients aged 50-70 years and 96 (26%) patients aged ≥80 years. Compared to 50-70-year olds, being ≥80 years old was associated with a nearly two-fold greater risk of no home return: adjusted HR: 1.96,95% CI 1.43-2.67. The oldest-old was at significantly increased risk of both being discharged to a skilled nursing facility or subacute rehabilitation (adjusted HR: 2.19,95% CI 1.33-3.59) as well as of dying in the hospital (adjusted HR: 1.81,95% CI 1.21-2.71). Conclusion: Previously home-dwelling oldest-old are at significantly increased risk of failing to return home immediately following medical ICU admission with IMV as compared to patients aged 50-70 years. These results can help medical ICU staff establish appropriate expectations when addressing the families of their oldest patients. Further studies are needed to evaluate the potential for delayed home return among the oldest old and to assess the ability of frailty indices to predict home return within this ICU population.
