Abstract

Lower acute kyphosis (LAK) is a postural deformity caused by severe osteoporotic vertebral collapse at the thoracolumbar junction. Corrective surgery is indicated for severe cases, but no case report using a fresh-frozen femoral head allograft was found in the English literature. A 69-year-old Japanese woman with severe LAK with osteoporotic vertebral fractures from T11 to L2 complained of severe back pain and difficulty in walking. The rigid kyphosis measured 74 degrees from T10 to L3. The patient underwent an anterior release and interbody fusion using a fresh-frozen femoral head allograft (T11-L3) and a posterior instrumented fusion (T10-L3). Postoperatively, kyphosis was corrected to 28 degrees , and the patient's symptoms were alleviated. The allograft bone was fully incorporated 1 year postoperatively. A new vertebral fracture at T10 occurred after 2 years, resulting in a slight loss of correction. A kyphosis angle of 35 degrees at 2 years was maintained at 12 years (age, 81 years). She remained free of back pain and able to walk without a cane over the 12-year follow-up. For treatment of severe osteoporotic LAK, anterior reconstruction is essential to obtain good spinal alignment and prevent recurrence. A fresh-frozen fe...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.
