A clinical feature of surgery in congenital radioulnar synostosis is described. A eighteen year old right handed woman, was hampered when she works by a left congenital radio ulnar synostosis. Clinical examination showed a left forearm locked in 75 degrees of pronation. Radiographs showed a proximal synostosis. Surgical treatment associated a resection of the synostosis with silastic interposition, resection of the distal end of the ulna, and derotational middle-third osteotomy of the radius. Three months later, the pronosupination was 90 degrees, but an ischemic retraction of the flexor pollicis longus muscle appeared with a non-union of the radius. A second procedure was necessary to put a plate in compression on bone and to release the muscle. Twenty years later, the forearm was locked in neutral pronosupination, without recurrence of synostosis on radiographs. Surgical treatment in congenital radio ulnar synostosis associates many problems: indication (often for discomfort), ideal age (more vascular or nervous post operative complications if older), technical (failure of operations with functional aim). A review of international litterature allows the authors to suggest a specific management for congenital radio ulnar synos...Continue Reading

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.

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.

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.

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.


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.

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.

Regulation of Vocal-Motor Plasticity

Dopaminergic projections to the basal ganglia and nucleus accumbens shape the learning and plasticity of motivated behaviors across species including the regulation of vocal-motor plasticity and performance in songbirds. Discover the latest research on the regulation of vocal-motor plasticity here.

Myocardial Stunning

Myocardial stunning is a mechanical dysfunction that persists after reperfusion of previously ischemic tissue in the absence of irreversible damage including myocardial necrosis. Here is the latest research.
