Abstract

The main techniques and results in stereotactic radiosurgical treatment of endocranial AVM's are described and compared. The authors also report their preliminary experience in the treatment of 6 consecutive pediatric patients with intracerebral vascular malformations using gamma knife (GK) radiosurgery. The various stereotactic radiosurgery methods currently used (charged-particle beam, modified linear accelerator, and GK) are described. At the Department of Neurosurgery in Verona, from February 1993 to February 1996, stereotactic GK radiosurgery was performed on 721 patients, including 20 of pediatric age (3%). Of the 78 AVMs, 7 (9%) were diagnosed in children. One patient was lost at follow-up. Among the remaining 6 children, there were 3 males and 3 females with a mean age of 12.3 years (range, 5-16 years). Treatment general anesthesia was needed only in 1 case. The AVM volume was always less than 10 cc. After completion of the procedure, children were discharged from the hospital the following day. The follow-up period ranged from 4 months to 29 months (median 18.8 months). The angiographic confirmed total obliteration is used as the end point of an AVM treated radiosurgically, and usually requires 2 to 3 years. All the pa...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.
