まとめ
ゲレオフイジック異形成症(GD)は、まれな骨格疾患であり、視神経乳頭ドルーゼンおよび網膜神経節細胞機能障害を呈することがある。影響を受ける子供たちにとって、早期の眼科的評価が重要である。
科学分野:
- 遺伝学
- 眼科学
- 骨異形成症
背景:
- ゲレオフイジック異形成症(GD)は、まれな遺伝性骨格疾患である。
- 低身長、特徴的な顔貌、皮膚肥厚、心臓の問題を特徴とする。
研究 の 目的:
- 新規の眼病変を伴うGDの症例を報告すること。
- GD患者における包括的な眼科検査の重要性を強調すること。
主な方法:
- GDの3歳男児の症例報告。
- 遺伝子検査により、FBN1遺伝子のヘテロ接合型c.5198G>Aバリアントが同定された。
- 眼科検査には、眼底検査、眼球超音波検査、光覚反応(PhNR)、およびパターン視覚誘発電位(VEP)が含まれた。
主要な成果:
- 患者は斜視、眼圧上昇、および視神経乳頭ドルーゼンと一致する所見を呈した。
- PhNR検査では振幅の低下が明らかになり、網膜神経節細胞機能障害を示唆した。

Pharmacokinetics in Pediatric Patients: Drug Excretion
225
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
285
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,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism
213
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption
272
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...

Antigens Involved in Adaptive Immunity
1.4K
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.

Patient-centered Care
3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
