Insights

Temporomandibular joint (TMJ) arthritis affects 43% of children with juvenile idiopathic arthritis (JIA). Mouth-opening deviation is a key risk factor, suggesting routine MRI evaluation for JIA patients is needed.

Area of Science:

  • Pediatric Rheumatology
  • Medical Imaging
  • Orthodontics

Background:

  • Juvenile idiopathic arthritis (JIA) can affect various joints, including the temporomandibular joint (TMJ).
  • TMJ involvement in JIA may lead to significant morbidity.
  • Limited data exists on TMJ arthritis prevalence and risk factors in pediatric JIA patients.

Purpose of the Study:

  • To determine the prevalence and MRI features of TMJ arthritis in children with JIA.
  • To identify clinical and demographic risk factors associated with TMJ arthritis in this population.

Main Methods:

  • Retrospective chart review of 187 JIA patients who underwent TMJ MRI.
  • Demographic and clinical data abstraction.
  • Univariate and multivariate analyses to identify risk factors for TMJ arthritis.

Main Results:

  • TMJ arthritis detected in 43% of JIA patients via MRI.
  • Mouth-opening deviation strongly associated with TMJ arthritis (OR 6.21).
  • Smaller maximal incisal opening and shorter disease duration also increased TMJ arthritis risk.

Conclusions:

  • TMJ arthritis is prevalent in children with JIA across all disease categories.
  • Routine TMJ MRI evaluation is recommended for all JIA patients.
  • Identifying risk factors like mouth-opening deviation can aid early detection and management.

Development of the Limb Synovial Joints01:07

Development of the Limb Synovial Joints

Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
During development, the limbs...
The JAK-STAT Signaling Pathway01:20

The JAK-STAT Signaling Pathway

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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

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...

Bone Disorders01:29

Bone Disorders

Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Tonsillitis I: Introduction

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
