Structural Joints: Cartilaginous Joints

Structural Joints: Cartilaginous Joints

As the name indicates, at a cartilaginous joint, the adjacent bones are united by cartilage, a tough but flexible type of connective tissue. Unlike synovial joints, these types of joints lack a joint cavity and involve bones joined together by either hyaline cartilage or fibrocartilage.
There are two types of cartilaginous joints:
Synchondrosis
A synchondrosis ("joined by cartilage") is a cartilaginous joint where bones are connected by hyaline cartilage. Synchondrosis may be temporary or...

Rheumatic Heart Disease I: Introduction

Rheumatic Heart Disease I: Introduction

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...

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...

Acute Pharyngitis

Acute Pharyngitis

Introduction
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Functional Classification of Joints

Functional Classification of Joints

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.
Synarthrosis
An immobile...

Tonsillitis I: Introduction

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.
Etiology
Three primary contributing factors have been identified.

Summary

This summary is machine-generated.

Arthralgia, or joint pain without clear signs of injury, affects children and adolescents, often in the knee or hip. Diagnosis involves medical history, physical exams, and imaging to identify various causes like arthritis or growing pains.

Area of Science:

Pediatric Rheumatology
Orthopedics
Musculoskeletal Disorders

Background:

Arthralgia is defined as joint pain without apparent clinical signs of arthritis or trauma.
In pediatric populations, common sites include the knee, hip, and ankle.
Numerous conditions can manifest as arthralgia, ranging from systemic diseases to localized joint issues.

Purpose of the Study:

To delineate the diverse etiologies of arthralgia in children and adolescents.
To highlight diagnostic approaches for joint pain in pediatric patients.
To differentiate between clearly diagnosable and vague presentations of arthralgia.

Main Methods:

Review of common causes of pediatric arthralgia.
Emphasis on clinical history and physical examination findings.
Integration of diagnostic tools including X-rays and laboratory studies.
Inclusion of observational methods like gait analysis for complex cases.

Main Results:

Identified a broad spectrum of potential causes for pediatric arthralgia.
Highlighted the diagnostic utility of standard clinical and radiological assessments.
Emphasized the role of careful observation in diagnosing less apparent cases of joint pain.

Conclusions:

Pediatric arthralgia encompasses a wide differential diagnosis.
A combination of history, physical examination, and investigations aids in diagnosis.
Subtle clinical signs and gait analysis are crucial for diagnosing challenging presentations.
