Abstract

The purpose of this investigation was to determine the prevalence of bone marrow signal abnormalities in patients referred for temporomandibular joint (TMJ) magnetic resonance imaging (MRI). This investigation was done because of prior studies suggesting that condylar marrow signal abnormalities indicate avascular necrosis. Retrospective review was done of 449 consecutive TMJ MR examinations in 415 patients from 1991 to 1994. Examinations were obtained with a surface coil at 1.5 T with routine T1, T2, and T2* images. Condylar marrow signal abnormalities were reviewed and classified into either a bone marrow edema pattern (hypointense T1, hyperintense T2) or a sclerosis pattern (hypointense T1 and hypointense T2). Patients with typical findings of osteoarthritis were excluded from the sclerosis category. Condylar marrow signal abnormalities were present in 37 patients (9%). Twenty-six patients (6%) had the edema pattern, 14 patients (3%) had the sclerosis pattern, and 3 patients had both. Two patients with the edema pattern had a history of surgery; five patients with the sclerosis pattern had a history of surgery. The only follow-up MRIs obtained in the 37 patients were on one patient with edema at 8 months and on one patient w...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.
