Abstract

Nail dynamization is one of the proposed surgical options to manage femoral shaft non-union. This study aims to assess the efficacy and the ideal timing for dynamization in patients with femoral shaft delayed union or non-union. Sixty-eight patients (38 male and 30 female, mean age 36.85 years old, range 22-58) were recruited. The patients were divided into three groups according to the fracture healing time: groupa A, fracture healing occurred within nine months; group B, fracture healing occurred between nine and 12 months; and group C, fracture healing after 12 months or secondary procedure needed for union. Callus-to-diaphysis ratio was calculated on femur X-rays at the time of dynamization. In 30 patients out of 68, the fracture healing was observed at nine month follow-up; in 26 patients, the fracture healed within 12 months; eight fractures healed in more than 12 months and only four fractures required a secondary procedure for union. Dynamization was successful in 64 patients out of 68 (94.12%). The mean callus-diaphysis ratio was significantly different in group A (p = 0.001) and in group B (p = 0.03), compared with group C. The timing of dynamization resulted significantly different between the three groups. Linear re...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.
