概括
大脑磁共振成像 (MRI) 建议所有被诊断为生长激素缺乏症 (GHD) 的儿童. 这是因为某些生化标志物不足以预测所有潜在的脑部异常,如垂体缺血等.
科学领域:
- 儿科内分泌学 儿科内分泌学
- 神经成像是一种神经成像.
- 遗传学 是一个遗传学.
背景情况:
- 关于对所有生长激素缺乏症 (GHD) 的儿童进行脑部MRI的必要性存在争议,特别是那些轻度病例的儿童.
- 识别儿科GHD下垂体或内异常的预测因子对于适当的诊断和治疗策略至关重要.
研究的目的:
- 为了确定患有GHD的儿童下垂体或内异常的频率.
- 识别可能预测这些异常的风险因素.
主要方法:
- 从95名儿科GHD患者的医疗记录和脑部MRI扫描进行了回顾性审查.
- 对胰岛素样生长因子I (IGF-I),IGF-I标准偏差得分 (SDS),胰岛素样生长因子结合蛋白3 (IGFBP3) 和生长激素 (GH) 峰值水平的血清水平的分析.
主要成果:
- 在14.7%的患者中存在异常的大脑MRI发现,包括垂体缺血症 (10.5%) 和垂体茎中断综合征 (4.2%).
- 较低的IGF-I,IGF-I SDS,IGFBP3和GH峰值水平的血清水平与异常的大脑MRI显著相关.
- IGF-I SDS < -1.365 显示大脑异常的高预测值 (85%的灵敏度,71.4%的特异性).
结论:
- 像IGF-I,IGF-I SDS,IGFBP3和GH峰值水平这样的生化标志物对儿科GHD中所有大脑异常具有显著但不足的预测能力.
- 该研究建议对所有被诊断患有GHD的儿童进行脑部MRI,因为可能出现不可预测的异常.

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 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...

Major Hormones and Their Functions
320
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...

Hypoglycemia and Glucagon
150
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...

Hormones of the Pituitary Gland
6.3K
The small, pea-sized pituitary gland is located at the base of the brain. It is crucial in regulating various bodily functions, from growth to reproduction. The gland is divided into the anterior lobe and the posterior lobe. The secretory cell clusters in the pars distalis of the anterior pituitary lobe are controlled by hypothalamic regulators and synthesize six primary hormones.
The most abundantly secreted hormone from the anterior lobe is the growth hormone, which controls overall growth by...

Signs of Puberty
235
Puberty is a critical phase, typically beginning between the ages of 8 and 13 in girls and 9 and 14 in boys, though timing can vary based on genetics, environmental factors, and overall health. This period is characterized by the development of secondary sexual characteristics and the attainment of reproductive potential. Endocrine changes underpin puberty, with hormonal surges of Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH) instigated by Gonadotropin-Releasing Hormone (GnRH)...
