Abstract

A clinical study of the surgical procedure for cervical disc herniation was conducted. To describe microsurgical transdural discectomy with laminoplasty, and to assess the clinical outcome of this surgical technique. A posterior approach for cervical disc herniation has been considered risky, and few reports on a transdural approach to this disorder have appeared in the past decade. However, a transdural approach with recent innovations (a microsurgical technique, intraoperative spinal cord monitoring, and laminoplasty) has not been reported. For this study, 30 patients with myelopathy or radiculomyelopathy accompanied by cervical disc herniation, aged 30 to 77 years (mean, 55 years), underwent microsurgical transdural discectomy with laminoplasty. Preoperative images showed multisegmental disc degeneration, developmental canal stenosis, or both for all the patients. The intraoperative evoked spinal cord potentials were recorded for neurophysiologic assessment. The follow-up period averaged 52 months (range, 24-118 months). The operative time averaged 239 minutes (range, 160-340 minutes), and the mean blood loss was 169 mL (range, 30-701 mL). The Japanese Orthopedic Association score improved from 3.5 to 15 (mean, 11.4) before ...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.
