Radiologic findings in heart-lung transplantation: a preliminary experience

Abstract

The chest radiographic findings and pulmonary radionuclide studies of four patients who underwent heart-lung transplantation between May 1983 and June 1986 were reviewed retrospectively. The two long-term survivors both developed bronchiolitis obliterans (presenting at 32 months postoperatively in the first patient and 14.5 months postoperatively in the second). The etiology of this is likely to be multifactorial and includes pulmonary rejection which may develop without concomitant cardiac rejection. The radiologist must be alert to this complication in heart-lung transplantation. The chest radiographs in our two patients showed diminution of peripheral bronchovascular markings and overinflation. The importance of careful screening of the radiographs of potential donors to detect pneumonia is emphasized. In one patient, a unilateral pneumothorax spread contralaterally due to the absence of normal anatomic barriers. The "reimplantation response" was not a prominent feature and was seen in one patient only. This response has been observed in heart-lung transplant recipients during the second postoperative week. The radiologic appearance is that of interstitial edema not explained by any clinical or hemodynamic findings.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
