Abstract

Long-term studies have shown that 10% to 20% of patients continue to experience ankle pain years after tibial fracture, which causes poor functional results and dissatisfaction. The aim of this study was to show that there could be a talus injury in patients with a tibial shaft fracture and to reveal occult talus lesions with magnetic resonance imaging (MRI) examination. Fifty-two patients with a tibial shaft fracture, with closed epiphyses, not extending to the joint and with no problems in the application of MRI examination were included. All patients underwent intramedullary tibial nailing. Patients with a lesion detected on MRI were planned to be examined by MRI again at mean of 12 months later. Ankle function of the patients were evaluated with the American Orthopaedic Foot and Ankle Society, Freiburg, and Weber scoring systems at 3, 6, and 12 months postoperatively. At the first MRI, 22 (42.3%) patients with tibial shaft fracture were found to have talus lesions: 7 (13.5%) had osteochondritis dissecans, 12 (23.1%) had edema, and 3 (5.8%) had cysts. A second MRI was planned for patients with edema and osteochondritis dissecans at a mean of 12 months. Finally, at 12 months, MRI examinations revealed osteochondritis dissecan...Continue Reading

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.
