Abstract

The aims of this study on late-detected developmental dislocation of the hip (DDH) were to assess the outcome in patients aged 55 to 60 years and to define prognostic factors. The study included 60 patients (74 hips). Primary treatment was skin traction to obtain closed reduction, followed by hip spica plaster cast. There were 52 girls and eight boys with a mean age at reduction of 19.6 months (8 to 37). Criteria for good long-term outcome were no osteoarthritis (OA) or total hip arthroplasty (THA) and modified Harris Hip Score ≥ 80 points. The mean patient age at follow-up was 57.7 years (55 to 60). Good long-term clinical and radiographic outcome occurred in 39 of 73 hips (53%). In all, 24 hips (32%) had undergone THA at a mean patient age of 48.1 years (31 to 58). Survival analysis with conversion to THA as endpoint showed a reduction in survival from 100% at patient age 30 years to 62% at 58 years. Risk factors for poor outcome were age at reduction ≥ 1.5 years and residual dysplasia (Severin grades III/IV) at skeletal maturity. With a mean follow-up of patient age 58 years, the outcome of late-detected DDH, treated with traction and closed reduction, was satisfactory in more than half the hips. This indicates that the hip ...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.
