Summary
Advances in pediatric rheumatology have improved chronic arthritis classification. The International League of Associations for Rheumatology (ILAR) classification of juvenile idiopathic arthritis (JIA) aids research but requires revision for broader application.
Area of Science:
- Paediatric rheumatology
- Chronic arthritis in children and adolescents
- Rheumatic disease classification
Context:
- Over the past 15 years, significant progress has been made in paediatric rheumatology.
- Improvements in classifying chronic arthritis, a prevalent rheumatic condition in pediatric populations, have been a key development.
- The International League of Associations for Rheumatology (ILAR) introduced a new classification in 1995.
Purpose:
- To discuss the advances in paediatric rheumatology, focusing on the classification of chronic arthritis.
- To introduce the International League of Associations for Rheumatology (ILAR) classification system for juvenile idiopathic arthritis (JIA).
- To highlight the utility and limitations of the ILAR classification for juvenile idiopathic arthritis (JIA).
Summary:
- The ILAR classification, proposed in 1995, defines juvenile idiopathic arthritis (JIA) as heterogeneous forms of childhood arthritis.
- JIA is categorized into seven distinct groups based on clinical presentation, prognosis, and genetic factors, utilizing national pediatric rheumatology database data.
- While beneficial for international research, the ILAR classification has limitations and necessitates further refinement, particularly regarding its applicability in adult rheumatology.
Impact:
- Facilitated collaborative research and enhanced comparability of study findings in pediatric rheumatology.
- Provided a framework for understanding the heterogeneity of juvenile idiopathic arthritis (JIA).
- Identified areas for improvement in classification systems, addressing challenges in adult rheumatology applications.

01:26Asthma-II: Pathophysiology and Classification
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

01:22Rheumatic 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...
01:20Inflammatory Bowel Disease IV: Clinical Manifestations
Inflammatory bowel disease (IBD) encompasses two major chronic disorders—ulcerative colitis and Crohn’s disease—each characterized by relapsing episodes of gastrointestinal inflammation. Although they share certain clinical features, their patterns of involvement and manifestations differ in ways that aid diagnosis and guide management.Ulcerative ColitisUlcerative colitis is limited to the colon and rectum and involves continuous inflammation of the mucosal layer. The disease course is marked...
01:20The 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...

Functional Classification of Joints
The functional classification of joints is determined by the amount of mobility between the adjacent bones. Joints are functionally classified as a synarthrosis or immobile joint, an amphiarthrosis or slightly moveable joint, or as a diarthrosis, a freely moveable joint. Fibrous and cartilaginous joints can be functionally classified as either synarthroses or amphiarthroses, whereas all synovial joints are classified as diarthroses.

01:30Pulmonary Hypertension: Classification and Pathogenesis
Pulmonary hypertension (PH) is a severe health condition in which the mean pulmonary arterial pressure increases to 25 mmHg or more, even when the body is at rest. This high pressure in the blood vessels that transport blood from the heart to the lungs can cause various symptoms, including shortness of breath, can lead to right heart failure, and significantly affect the overall quality of life.
There are various classifications for PH, each relating to different underlying causes and also...
