Where on the Differential Is Eisenmenger Syndrome in a Patient Without Prior Cardiopulmonary Disease?

Cureus 2020 Jun 8;12(6):e8509. Epub 2020 Jun 8.

Internal Medicine, Cooper Medical School of Rowan University-Cooper University Health Care, Camden, USA.

Pulmonary hypertension (PH) can occur in patients with undiagnosed congenital heart disease, like atrial septal defects (ASDs), causing chronic left-to-right shunting. This may ultimately result in Eisenmenger physiology or syndrome (ES), a reversal of left-to-right shunting, resulting in a right-to-left shunt, thereby causing deoxygenated blood to enter systemic circulation as it bypasses the lungs. Development of PH due to an ASD is uncommon, and the occurrence of ES is <1% as most ASDs are corrected early in life. Read More

Interstitial lung abnormalities detected incidentally on CT: a Position Paper from the Fleischner Society.

Lancet Respir Med 2020 Jul;8(7):726-737

Department of Radiology, Denver, CO, USA.

The term interstitial lung abnormalities refers to specific CT findings that are potentially compatible with interstitial lung disease in patients without clinical suspicion of the disease. Interstitial lung abnormalities are increasingly recognised as a common feature on CT of the lung in older individuals, occurring in 4-9% of smokers and 2-7% of non-smokers. Identification of interstitial lung abnormalities will increase with implementation of lung cancer screening, along with increased use of CT for other diagnostic purposes. Read More

From the Departments of Radiology (M.L., K.B., M.D.L., W.A.M., Jr, S.P.R.).

There is increasing evidence to suggest that complications of coronavirus disease 2019 (COVID-19) infection are not only limited to the pulmonary system but can also involve the central nervous system. Here, we report 6 critically ill patients with COVID-19 infection and neuroimaging findings of leukoencephalopathy. While these findings are nonspecific, we postulate that they may be a delayed response to the profound hypoxemia the patients experienced due to the infection. Read More

Imaging findings in coronavirus infections: SARS-CoV, MERS-CoV, and SARS-CoV-2.

Br J Radiol 2020 Jul 6:20200515. Epub 2020 Jul 6.

Department of Radiology, Samsung Medical Center, Sungkyunkwan University School of Medicine (SKKU-SOM), Seoul, Korea.

During the first two decades of the 21st century, there have been three coronavirus infection outbreaks raising global health concerns by severe acute respiratory syndrome coronavirus (SARS-CoV), the Middle East respiratory syndrome coronavirus (MERS-CoV), and the SARS-CoV-2. Although the reported imaging findings of coronavirus infection are variable and non-specific, the most common initial chest radiograph (CXR) and CT findings are ground-glass opacities and consolidation with peripheral predominance and eventually spread to involve both lungs as the disease progresses. These findings can be explained by the immune pathogenesis of coronavirus infection causing diffuse alveolar damage. Read More

Acute pneumonitis and diffuse alveolar hemorrhage secondary to silicone embolism: A case report.

Medicine (Baltimore) 2020 Jun;99(24):e20578

Faculty of Health Sciences, Universidad Icesi.

Rationale: Polydimethylsiloxane, commonly referred as silicone, is an inert liquid compound used in esthetic procedures due to its durability and thermal stability, yet the application of non-pure silicone generates risks. One of the complications is systemic embolism syndrome which is presents with fever, hypoxemia, and progression to respiratory failure, diffuse alveolar damage and alveolar hemorrhage, as well as neurological alterations in one-third of the cases. Management is strictly supportive. Read More

[Auxiliary Diagnostic Value of Tumor Markers in the Cerebrospinal Fluid and Blood for Leptomeningeal Metastasis from Non-small Cell Lung Cancer].

Zhongguo Fei Ai Za Zhi 2020 Jun;23(6):516-525

Department of Geriatric, the First Affiliated Hospital of Nanjing Medical University, Nanjing 210029, China.

Background: Leptomeningeal metastasis (LM) is one of the most common causes of death in patients with advanced non-small cell lung cancer (NSCLC), which is defined as malignant cells spreading to meninges and cerebrospinal fluid (CSF). Therefore, early diagnosis and timely treatment are essential. CSF cytology is the gold standard for LM diagnosis, however, it has a low sensitivity for diagnosis and can't be used to evaluate the treatment effect. Read More

Characteristic and quantifiable COVID-19-like abnormalities in CT- and PET/CT-imaged lungs of SARS-CoV-2-infected crab-eating macaques ().

bioRxiv 2020 May 14. Epub 2020 May 14.

Integrated Research Facility at Fort Detrick, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Fort Detrick, Frederick, MD 21702, USA.

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is causing an exponentially increasing number of coronavirus disease 19 (COVID-19) cases globally. Prioritization of medical countermeasures for evaluation in randomized clinical trials is critically hindered by the lack of COVID-19 animal models that enable accurate, quantifiable, and reproducible measurement of COVID-19 pulmonary disease free from observer bias. We first used serial computed tomography (CT) to demonstrate that bilateral intrabronchial instillation of SARS-CoV-2 into crab-eating macaques () results in mild-to-moderate lung abnormalities qualitatively characteristic of subclinical or mild-to-moderate COVID-19 (e.

Maternal SLE and brachytelephalangic chondrodysplasia punctata in a patient with unrelated de novo RAF1 and SIX2 variants.

Am J Med Genet A 2020 Jul 7;182(7):1807-1811. Epub 2020 Jun 7.

The Prenatal Diagnosis and Medical Genetics Program, Department of Obstetrics and Gynecology, Mount Sinai Hospital, University of Toronto, Toronto, Ontario, Canada.

Our improved tools to identify the aetiologies in patients with multiple abnormalities resulted in the finding that some patients have more than a single genetic condition and that some of the diagnoses made in the past are acquired rather than inherited. However, limited knowledge has been accumulated regarding the phenotypic outcome of the interaction between different genetic conditions identified in the same patients. We report a newborn girl with brachytelephalangic chondrodysplasia punctata (BCDP) as well as frontonasal dysplasia, ptosis, bilateral hearing loss, vertebral anomalies, and pulmonary hypoplasia who was found, by whole exome sequencing, to have a de novo pathogenic variant in RAF1 (c.
