まとめ
片側性持続性胎児血管系(PFV)の小児は、影響を受けた眼において有意に高い角膜乱視(CA)を有する。これらの眼における最も急峻な角膜子午線は、主に垂直である。
科学分野:
- 眼科学;小児眼科学;角膜疾患
背景:
- 持続性胎児血管系(PFV)は、眼の発達に影響を与える先天性疾患である。;早期介入のためには、PFVサブタイプとその関連視覚障害の理解が不可欠である。
研究 の 目的:
- 持続性胎児血管系(PFV)サブタイプの分布を分類すること。;片側性PFVと診断された小児における角膜乱視(CA)を評価すること。
主な方法:
- 133例のPFV患者記録(2014-2021年)の後ろ向きレビュー。;IOLMasterまたはハンドヘルド角膜 कोणमिति計を用いて角膜 कोणमिति(corneal keratometry)を測定した。;52例の片側性PFV症例における影響を受けた眼と対側の眼との間のCAの比較。
主要な成果:
- 複合型前部-後部PFVが最も一般的なサブタイプ(74.44%)であった。;片側性PFV症例における影響を受けた眼は、対側の眼(1.37 D)と比較して有意に高い平均CA(2.29 D)を示した。;CAが2.0 D以上の影響を受けた眼では、最も急峻な角膜子午線は96.77%の症例で垂直であった。
結論:
- 片側性PFVは、影響を受けた眼における角膜乱視の有意な増加と関連している。;PFV影響を受けた眼における角膜の最も急峻な子午線の垂直配向は、主な所見である。

Adrenergic Receptors: ɑ Subtype
2.8K
Adrenoceptors are classified into α and ꞵ classes based on their potencies to catecholamine agonists. α-adrenoceptors show the following order of catecholamine potency:
Adrenaline ≥ Noradrenaline >> Isoprenaline
α-adrenoceptors are further divided into α1 and α2-adrenoceptors.
α1-Adrenoceptors: These receptors are located postsynaptically on the effector organs and cause constriction of smooth muscle mediated by activation of phospholipase...

Adrenergic Receptors: β Subtype
3.7K
β-adrenoceptors have varied sensitivities towards adrenaline, noradrenaline, and isoprenaline. The order of agonist potency is as follows:
Isoprenaline > Adrenaline > Noradrenaline
Neurotransmitter binding to these receptors causes activation of adenylyl cyclase resulting in increased concentrations of cAMP and modulation of calcium ion channels within the cell. They are further classified into β1, β2, and β3 subtypes.
β1-adrenoceptors: β1-adrenoceptors...

Fetal Circulation
2.7K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Diabetes Mellitus: Overview and Type I Subtype
5.0K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

Pharmacokinetics in Pediatric Patients: Drug Excretion
214
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Drug Distribution

Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...
