Abstract

Since low-invasive surgery provides marked symptomatic improvement of patients with chronic subdural hematoma, surgery will be recommended also for the aged. To examine the clinical features and treatment result in the aged patients, we compared the clinical features and surgical results in two groups of patients with 80 or more and less than 80 years. The subjects consisted of 266 adult patients with a total of 333 chronic subdural hematomas who had undergone closed-system drainage between January 1995 and March 2005. The items analyzed were 1) patients background including gender, laterality of hematoma, presence or absence of history of head trauma, history of drinking, and mechanism of injury, 2) clinical symptoms, such as level of consciousness on initial examination, initial symptoms, and the degree of paralysis, 3) those related to surgery, such as time from injury to surgery, length of hospital stay, operation time, and amount of drainage, 4) outcome, such as presence or absence of symptomatic improvement, and recurrence rate. The results of this study showed that chronic subdural hematomas in the extremely aged patients were characterized by 1) infrequent history of head trauma, 2) infrequent headache and frequent deme...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.
