Bone Disorders01:29

Bone Disorders

7.8K
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...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

1.0K
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 I: Introduction

881
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...

Nature and Nurture01:10

Nature and Nurture

22.8K
Many human characteristics, like height, are shaped by both nature—in other words, by our genes—and by nurture, or our environment. For example, chronic stress during childhood inhibits the production of growth hormones and consequently reduces bone growth and height. Scientists estimate that 70-90% of variation in height is due to genetic differences among individuals, and 10-30% of variation in height is due to differences in the environments that individuals experience,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

745
Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Role of Hematopoietic Growth Factors01:28

Role of Hematopoietic Growth Factors

4.4K
Hematopoietic growth factors are molecules that regulate the differentiation rate of hematopoietic stem cells (HSCs). Erythropoietin (EPO), primarily produced by the kidneys, plays a crucial role in erythrocyte production. When oxygen levels in the blood are low, EPO is released into the bloodstream, reaching the bone marrow, where it stimulates HSCs to differentiate and mature into erythrocytes, which are vital for oxygen transport.
Thrombopoietin (TPO), mainly released by the liver,...

Area of Science:

  • Pediatric rheumatology
  • Endocrinology
  • Growth disorders

Background:

  • Growth impairment is a significant complication in pediatric rheumatologic diseases like juvenile idiopathic arthritis, systemic lupus erythematosus, and systemic sclerosis.
  • Chronic inflammation, malnutrition, endocrine dysfunction, and glucocorticoid toxicity contribute to growth suppression in affected children.
  • Despite advancements in biologic therapies, persistent growth delays remain a challenge, impacting adult height.

Purpose of the Study:

  • To review the mechanisms underlying growth suppression in pediatric rheumatologic conditions.
  • To describe disease-specific impacts on growth.
  • To discuss current therapeutic strategies for optimizing linear growth and development.

Main Methods:

  • Literature review synthesizing current knowledge on growth impairment in pediatric rheumatologic diseases.
  • Analysis of mechanisms including inflammation, endocrine signaling, nutrition, and medication effects.
  • Discussion of contemporary treatment approaches.

Main Results:

  • Pediatric rheumatologic diseases significantly impair growth through multifactorial pathways.
  • Biologic therapies have improved disease control and growth potential but do not fully resolve growth deficits in all cases.
  • Glucocorticoid toxicity is a notable contributor to medication-related growth suppression.

Conclusions:

  • Understanding the complex mechanisms of growth suppression is crucial for managing pediatric rheumatologic diseases.
  • Multifaceted therapeutic strategies are needed to address persistent growth delays and optimize outcomes.
  • Further research into optimizing linear growth in children with rheumatologic conditions is warranted.
