Abstract

Out of a total of 435 cases of nucleolysis, 400 case-reports of which could be used, secondary surgery was performed in 48 cases or 12% of the total. Surgery was most frequently required following L4/L5 than L5/S1 nucleolysis. The most frequent causes of failure of nucleolysis were lateral osseous stenosis (19 cases) and sub-ligamentous hernia (17 cases), apparently due to the ineffectiveness of the enzyme. Excluded hernia was rare (4 cases). Hernias at another level (4 cases) required surgery since it was not possible to repeat the injection of chymopapain. Three of these explorations were of the linea alba and one failure was due to spondylolisthesis due to isthmic lysis. Some failures occurred after some delay. The sciatic relapses after a period of complete clinical cure. In some cases, the relapse was in fact at another level or involved sub-ligamentous or excluded hernia. Surgery following nucleolysis is the same as that of an uninjected hernia; there are no adherences. The results are generally the same as those obtained by primitive surgery (two thirds favorable outcome). However, this depends mainly on what has been detected. The results are very good for hernias at another level and for excluded hernias. Fair results ...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.
