まとめ
定期的な産前超音波検査は,子供の読み書き能力に影響を与えない. ある研究では,子宮内超音波に曝された子どもと,曝されなかった子どもとの間で,学業成績や難読率において有意な差異は認められなかった.
科学分野:
- 産婦人科と産婦人科を担当しています.
- 発達小児科 発達小児科
- 神経科学は神経科学である.
背景:
- 診断用超音波検査は先進国では一般的であり,胎児への潜在的な害に関する懸念を提起しています.
- 定期的な超音波検査は,胎児の脳発達期 (16-22週間) の重要な時期に行われるため,神経細胞の移動への影響について調査を促した.
- 以前の研究は,産前超音波曝露と長期の認知または学術的な結果との関連を明確に確立していない.
研究 の 目的:
- 定期的な子宮内診断超音波検査と小学生の読み書き能力の発達との関連を調査する.
- 生前超音波曝露が学業成績や難読症の有病率に及ぼす潜在的な影響を評価する.
主な方法:
- ノルウェー (1979年−1981年) で実施された2つのランダム化対照試験による通常の産前超音波検査の子ども (8~9歳) のフォローアップ研究.
- 2011年の子どもたちの学校での成績 (読書,綴り,算数,全体) を教師が1から7のスケールで報告した (83%のフォローアップ).
- 603人の子供のサブグループで,読書,綴り,知性,不一致を評価する特定の難読症のテストを行いました.
主要な成果:
- 定期的な産前超音波検査を受けた子どもと対照群の間で,教師による学校の成績の統計的に有意な差は見つかりませんでした.
- ディスレクシア検査は,スクリーニングと対照群の間で,読書,綴り,または知能スコアにおいて有意な違いを示さなかった.
- ディスレクシアの罹患率は両グループでほぼ同じで,スクリーニングを受けたグループでは7%,対照群では9%であった.
結論:
- 妊娠中の通常の診断用超音波検査は,小学生の読み書き能力に悪影響を及ぼさない.
- 産前超音波スクリーニングは,学力低下や難読症のリスクを増加させるようには見えません.
- 現在の証拠は,定期的な胎児の超音波検査は,後の識字能力の発達に関して安全であることを示唆しています.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:25Assessment of the Abdomen I: Inspection and Auscultation
Introduction
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen

01:18Assessment of the Abdomen II: Percussion
Percussion is a fundamental technique used to assess the liver, spleen, and abdominal organs by tapping the abdomen and interpreting the resulting sounds. This method helps identify fluid, distention, and masses through variations in sound, such as the high-pitched tympany of air-filled areas and the dullness of solid masses. Understanding how to percuss these organs provides valuable information for healthcare professionals in diagnosing conditions early.

01:25Cardiovascular System Abnormal Findings II: Auscultation
Auscultation, an essential part of a heart examination, is done using a stethoscope. It provides crucial information about heart function and possible heart problems. Due to heart problems, abnormal sounds can be heard during systole or diastole. These sounds include S3 and S4 gallops, opening snaps, systolic clicks, and murmurs.
