Abstract

Instability remains one of the most common indications for revision THA. However, little is known about the efficacy of surgery for and the complications associated with revision THA for patients with a chronically dislocated THA, which we define as a dislocation of more than 4 weeks. For patients with a chronically dislocated THA undergoing revision THA, we asked (1) What is the survivorship free from additional revision for these procedures? (2) What complications are associated with revision THA in this setting? (3) What are the clinical outcomes as measured by the Harris hip score in these procedures? From 1998 to 2014, 1084 patients who underwent revision THA for instability were reviewed and 33 patients (33 hips) were identified who had a hip that had been dislocated for more than 4 weeks. Median time dislocated was 4 months (range, 1-120 months), and the mean distance of the femoral head above hip center at presentation was 45 mm. Mean patient age was 67 ± 17 years, and 79% of patients (26 of 33) were women. During the period in question, we used four approaches: Treatment with acetabular component revision in 18 of 33 patients (55%), head and liner exchange in nine patients (27%), both-component revision in five patient...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.
