Summary
Joint replacement surgery does not increase dermatitis risk overall. However, younger patients (<60 years) may experience a higher risk of developing dermatitis after joint replacement.
Area of Science:
- Orthopedic Surgery
- Dermatology
- Epidemiology
Background:
- Joint replacement surgery involves implanting prostheses made from metal, plastic, or ceramic materials.
- Patients may develop skin reactions, including dermatitis, due to hypersensitivity to these implant materials.
Purpose of the Study:
- To investigate the association between joint replacement surgery and the subsequent development of dermatitis.
- To identify any specific patient demographics or factors influencing this relationship.
Main Methods:
- A nationwide, population-based retrospective cohort study was conducted using South Korean National Health Insurance Service data.
- 40,218 patients undergoing joint replacement were compared with 40,218 controls.
- Cox proportional hazard and Fine and Gray regression models were employed to assess dermatitis risk.
Main Results:
- Overall, 9.2% of the joint replacement group and 9.1% of the control group developed dermatitis, with no statistically significant difference.
- Regression models indicated no increased risk of dermatitis post-joint replacement in the general cohort.
- A significant 1.20-fold increased risk of dermatitis was observed in patients under 60 years old who underwent joint replacement.
Conclusions:
- Joint replacement surgery is not associated with an increased risk of dermatitis in the overall population.
- However, a notable increase in dermatitis risk was identified in patients younger than 60 years following joint replacement.
- Age appears to be a critical factor in the development of dermatitis after joint replacement.

Connective tissue develops from the mesoderm of a developing embryo and consists of cells, fibers, and ground substance: a gel-like material containing large complexes of carbohydrates and proteins. Connective tissue was first identified as a separate tissue family in the 18th century, and Johannes Peter Muller coined the term connective tissue.
Fat cells (adipocytes), smooth muscle cells (myoblasts), and bone cells (osteoblasts) are some connective tissue cell types. Some immune system cells...

14.0K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

01:20The JAK-STAT Signaling Pathway
9.1K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...
