Abstract

In the literature little is to be found concerning diagnosis and differential diagnosis of Kienböck's disease. Because of technical development in radiological imaging, we now possess very detailed pictures. However, there are many radiological findings within the lunate bone, which can be misinterpreted as Kienböck's disease. Pathological findings of the lunate bone are demonstrated, which are not Kienböck's disease. These findings were compared to different stages of Kienböck's disease and identified. The early stages of Kienböck's disease show changes especially in the MRI, which are very similar to acute bone bruise, ulnar impaction syndrome, synovialitis or gout. Vessel tubes or an intraosseous ganglion can be mistaken for Kienböck's disease. In the late stages of Kienböck's disease, it can be difficult to differentiate this from pseudarthrosis of the lunate bone. The differentiation between Kienböck's disease and other pathological findings is at times very difficult--even with MRI. However, sometimes diagnosis can only be verified by MRI. We therefore suggest that Kienböck's disease must be correctly diagnosed with help of the MRI before commencing with any therapeutic steps.

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.
