Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.8K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Hormones of the Adrenal Glands

6.3K
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and...

Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

69.4K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

Smooth Endoplasmic Reticulum01:21

Smooth Endoplasmic Reticulum

8.7K
Smooth endoplasmic reticulum or smooth ER is a sub-organelle with specialized functions in animal cells and plant cells. It is often associated with the tubule morphology of the endoplasmic reticulum.
The ER provides optimal conditions for synthesizing steroid hormones and lipids, such as phospholipids and triglycerides. Traditionally, lipid metabolism was considered to be a smooth ER function. However, there is no direct evidence to prove that rough ER is completely excluded from lipid...

Attention-Deficit/Hyperactivity Disorder

1.3K
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Anatomy of the Adrenal Glands01:17

Anatomy of the Adrenal Glands

5.6K
The adrenal or supra-renal glands, situated above the kidneys and aligned with the twelfth rib, are paired pyramid-shaped structures crucial for the body's stress response. During stress, these glands secrete hormones vital for adaptive physiological reactions.
These glands possess a distinctive yellow tinge due to the stored cholesterol and fatty acids required for hormone synthesis. They are encased in a fibrous capsule and cushioned by fat.
The adrenal gland comprises two distinct...

    Summary

    Congenital adrenal hyperplasia (CAH) in children has significant clinical features. Newborn screening using 17-OH-progesterone on filter paper offers crucial early detection, improving outcomes.

    Area of Science:

    • Pediatric Endocrinology
    • Genetics
    • Neonatal Screening

    Context:

    • Congenital adrenal hyperplasia (CAH) encompasses a group of genetic disorders affecting the adrenal glands.
    • These conditions present diverse clinical and physiopathological characteristics in pediatric patients.
    • Early identification and management are critical for improving long-term health outcomes.

    Purpose:

    • To review the clinical and physiopathological aspects of major CAH types in children.
    • To highlight the benefits of newborn screening for CAH using 17-hydroxyprogesterone (17-OHP) levels.
    • To emphasize the importance of prenatal diagnosis and management for at-risk pregnancies.

    Summary:

    • This review details the key clinical manifestations and underlying pathophysiology of prevalent CAH forms in pediatric populations.

  • It underscores the significant advantages of universal newborn screening via analysis of 17-OHP on filter paper blood samples.
  • The critical role of proactive treatment for high-risk pregnancies prior to delivery is also emphasized.

    • Impact:

    • Facilitates earlier diagnosis and intervention for congenital adrenal hyperplasia in newborns.
    • Enables timely management, potentially preventing severe health complications associated with CAH.
    • Supports informed clinical decision-making regarding prenatal care and neonatal screening strategies.
