Hypoglycemia and Glucagon01:15

Hypoglycemia and Glucagon

152
Without prolonged fasting, healthy individuals maintain blood glucose levels above 3.5 mM due to a well-adapted neuroendocrine counterregulatory system that effectively prevents acute hypoglycemia, a potentially life-threatening condition. The primary clinical scenarios for hypoglycemia encompass diabetes treatment, inappropriate production of endogenous insulin or insulin-like substances by tumors, and the use of glucose-lowering agents in non-diabetic individuals. Notably, hypoglycemia in the...

Major Hormones and Their Functions01:27

Major Hormones and Their Functions

328
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Nature and Nurture01:10

Nature and Nurture

20.4K
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,...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

1.3K
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...

Area of Science:

  • Pediatric Endocrinology
  • Neuroradiology
  • Neuroimaging

Background:

  • Growth hormone deficiency (GHD) presents as congenital or acquired.
  • Acquired GHD links to hypothalamic-pituitary axis issues, while congenital GHD may involve subtle structural abnormalities.
  • Brain magnetic resonance imaging (MRI) is essential for detecting these abnormalities and informing prognosis.

Purpose of the Study:

  • To provide a neuroradiologist's perspective on assessing pediatric growth hormone deficiency.
  • To review common hypothalamic-pituitary findings in pediatric GHD.
  • To outline normal pituitary gland MRI appearance and technical imaging requirements.

Main Methods:

  • Review of pediatric GHD assessment from a neuroradiological viewpoint.
  • Overview of pituitary gland development.
  • Analysis of normal pituitary MRI appearance and technical considerations for sellar/supra-sellar imaging.

Main Results:

  • MRI reveals diverse pathological processes impacting the hypothalamic-pituitary axis in GHD.
  • Specific findings correlate with congenital versus acquired GHD etiologies.
  • Understanding normal anatomy and technical requirements optimizes diagnostic yield.

Conclusions:

  • Brain MRI is a cornerstone in evaluating pediatric growth hormone deficiency.
  • Neuroradiological assessment is vital for identifying structural causes and guiding management.
  • Standardized imaging protocols ensure comprehensive evaluation of the sellar and supra-sellar regions.
