Interstitial lung abnormalities: erecting fences in the path towards advanced pulmonary fibrosis.

Thorax 2019 Feb 5. Epub 2019 Feb 5.

Interstitial lung abnormalities, when present in members of undiagnosed family members recruited on the basis of familial interstitial pneumonia, or in undiagnosed research participants, have been associated with a syndrome that includes distinct sets of imaging abnormalities, restrictive physiological and exercise impairments, and an increased prevalence of histopathological findings, and genetic predictors, that have been noted in patients with idiopathic pulmonary fibrosis. Recent longitudinal studies have demonstrated that qualitative and quantitative assessments of interstitial abnormalities are associated with accelerated lung function decline, an increased rate of clinical diagnoses of interstitial lung disease and an increased rate of mortality. In this perspective, in addition to reviewing the prior information, four major efforts that could help the field of early pulmonary fibrosis detection move forward are discussed. Read More

Noncontrast Chest Computed Tomographic Imaging of Obesity and the Metabolic Syndrome: Part II Noncardiovascular Findings.

J Thorac Imaging 2019 Jan 31. Epub 2019 Jan 31.

Departments of Radiology.

The purpose of this review article is to acquaint the reader with the current state of the art for the noncardiovascular imaging biomarkers of metabolic syndrome found on noncontrast computed tomography (NCCT) of the chest and their prognostic significance. Routine chest NCCT includes quantitative information with regard to tissue density and organ volumes in the neck, chest, and upper abdomen. The specific imaging biomarkers that may be seen in association with metabolic syndrome include low thyroid iodine organification, hepatic steatosis, sarcopenia (muscle volume and density), demineralization of the thoracic and upper lumbar vertebral bodies, loss of axial skeletal muscle mass, premature lung inflammation, and an increased deposition of subcutaneous and visceral fat.

SLIME: robust, high-speed 3D microvascular mapping.

Sci Rep 2019 Jan 29;9(1):893. Epub 2019 Jan 29.

Department of Biomedical Engineering, Case Western Reserve University, Cleveland, USA.

Three dimensional (3D) microvascular imaging of cubic millimeter to centimeter size volumes often requires much time and expensive instruments. By combining optical clearing with a novel scatter-based optical coherence tomography (OCT) contrast agent, we have greatly extended OCT imaging depth in excised tissues while maintaining a simple and low cost approach that does not require in-depth OCT knowledge. The new method enables fast 3D microvascular mapping in large tissue volumes, providing a promising tool for investigating organ level microvascular abnormalities in large cohorts. Read More

Isolated adrenocorticotropic hormone deficiency potentially induced by nivolumab following pseudo-progression in clear cell renal cell carcinoma: A case report.

Mol Clin Oncol 2019 Feb 30;10(2):304-308. Epub 2018 Nov 30.

Department of Urology, National Kyushu Cancer Center, Fukuoka 811-1395, Japan.

Nivolumab is a monoclonal immunoglobulin G antibody blocking programmed death receptor-1 (PD-1) that promotes the restoration of the natural T-cell-mediated immune response against cancer cells; however, it also causes a number of autoimmune-related adverse events (irAEs) that often involve the endocrine system. The present report describes a 71-year-old man with clear cell renal cell carcinoma metastasis in the lung. Following the 14th course of nivolumab therapy, the patient complained of general malaise, loss of appetite and mild consciousness disturbance. Read More

Complication Rates and Downstream Medical Costs Associated With Invasive Diagnostic Procedures for Lung Abnormalities in the Community Setting.

JAMA Intern Med 2019 Jan 14. Epub 2019 Jan 14.

Department of Health Services Research, The University of Texas MD Anderson Cancer Center, Houston.

Importance: The Centers for Medicare & Medicaid Services added lung cancer screening with low-dose computed tomography (LDCT) as a Medicare preventive service benefit in 2015 following findings from the National Lung Screening Trial (NLST) that showed a 16% reduction in lung cancer mortality associated with LDCT. A challenge in developing and promoting a national lung cancer screening program is the high false-positive rate of LDCT because abnormal findings from thoracic imaging often trigger subsequent invasive diagnostic procedures and could lead to postprocedural complications.

Objective: To determine the complication rates and downstream medical costs associated with invasive diagnostic procedures performed for identification of lung abnormalities in the community setting. Read More

Advanced pulmonary MRI to quantify alveolar and acinar duct abnormalities: Current status and future clinical applications.

J Magn Reson Imaging 2019 Jan 13. Epub 2019 Jan 13.

Department of Physics and Astronomy, University of Western Ontario, London, Canada.

There are serious clinical gaps in our understanding of chronic lung disease that require novel, sensitive, and noninvasive in vivo measurements of the lung parenchyma to measure disease pathogenesis and progressive changes over time as well as response to treatment. Until recently, our knowledge and appreciation of the tissue changes that accompany lung disease has depended on ex vivo biopsy and concomitant histological and stereological measurements. These measurements have revealed the underlying pathologies that drive lung disease and have provided important observations about airway occlusion, obliteration of the terminal bronchioles and airspace enlargement, or fibrosis and their roles in disease initiation and progression.

Congenital abnormalities of the aortic arch: revisiting the 1964 Stewart classification.

Cardiovasc Pathol 2018 Dec 6;39:38-50. Epub 2018 Dec 6.

Department of Obstetrics & Gynecology, Howard University, College of Medicine, Washington, DC 20060, USA. Electronic address:

The traditional classification of congenital aortic arch abnormalities was described by James Stewart and colleagues in 1964. Since that time, advances in diagnostic imaging technology have led to better delineation of the vasculature anatomy and the identification of previously unrecognized and unclassified anomalies. In this manuscript, we review the existing literature and propose a series of modifications to the original Stewart classification of congenital aortic arch abnormalities to incorporate this new knowledge.

Regional Referral Centre for Rare Lung Diseases, University Hospital "Policlinico", Dept of Clinical and Respiratory Medicine, University of Catania, Catania, Italy.

Imaging techniques are an essential component of the diagnostic process for interstitial lung diseases (ILDs). Chest radiography is frequently the initial indicator of an ILD, and comparison of radiographs taken at different time points can show the rate of disease progression. However, radiography provides only limited specificity and sensitivity and is primarily used to rule out other diseases, such as left heart failure. Read More

Neonatal lethal hypophosphatasia: A case report and review of literature.

Medicine (Baltimore) 2018 Nov;97(48):e13269

Neonatal Service, Metabolic Unit, Department of Pediatrics, Santiago de Compostela University Hospital, IDIS (Health Research Institute of Santiago de Compostela), Ciberer, Spain.

Rationale: Hypophosphatasia (HPP) is a very rare metabolic bone disease caused by loss-of-function mutations in the ALPL gene encoding the tissue nonspecific alkaline phosphatase. The severe neonatal form is considered lethal but insights into manifestations of the disease can help to increase our knowledge of the natural history for an early initiation of treatment and improvement of survival.

Patient Concerns: We report the case of a newborn in which his fetal imaging showed findings of skeletal dysplasia disorder, considering initially achondroplasia as a potential diagnosis. Read More
