研究 の 目的:
- EFIの小児患者の縦断的なフォローアップの必要性を評価する.
- 亜診断性エオシノフィール数を有するEFIが,確認されたEoE診断に進展できるかどうかを判断する.
- 適切な生検の調達と,EoEの診断のための内視鏡の再現の重要性を強調する.
主な方法:
- エンドスコーピカル評価を受けているEFIの小児患者の遡及的チャートレビュー.
- 食道バイオプシーのエオシノフィール数 (高電力のフィールド1分のエオシノフィール数 - HPF) の分析.
- 初期のサブ診断性エオシノフィルの数 (1-14/HPF) を有する患者の長期的評価.
主要な成果:
- EFIと亜診断性エオシノフィルの数 (1-14/HPF) を有する4人の小児患者が特定されました.
- 4人の患者全員が,エソファゲスのエオシノフィルの増加を繰り返し内視鏡検査 (≥15/HPF) で示した.
- 評価されたすべての患者でエオシノフィル性食道炎 (EoE) の診断が確認されました.
結論:
- 食道食物インパクト (EFI) は,エオシノフィル性食道炎 (EoE) の初期臨床的症状である可能性があります.

Barrett Esophagus-II: Clinical Manifestations and Management
1.2K
Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...

Esophageal Strictures-I: Introduction
927
Esophageal strictures involve abnormal narrowing or tightening of the esophagus. They vary in length and severity, ranging from mild constriction to complete obstruction, and are classified as benign (noncancerous) or malignant (cancerous).
Etiology
The primary cause of esophageal strictures is long-standing gastroesophageal reflux disease (GERD), accounting for about 70 to 80% of adult cases. Chronic acid reflux can lead to injury and scarring of the esophageal lining, culminating in...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal
2.7K
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Esophageal Strictures-II: Clinical Features and Management
718
Patients with esophageal strictures often experience a range of symptoms. Initially, they may have difficulty swallowing solid foods, which can progress to include liquids. Additional symptoms may involve chest pain or discomfort, regurgitating food and fluids, heartburn, unintentional weight loss, coughing or choking during meals, and hoarseness.
Healthcare providers should gather a comprehensive medical history and conduct a physical examination for diagnosis. If esophageal stricture is...

Barrett Esophagus-I: Introduction
960
Barrett's esophagus is a medical condition where the esophageal mucosa is significantly damaged by stomach acid or other digestive fluids, often due to long-term exposure associated with gastroesophageal reflux disease (GERD). In GERD, a weakened or abnormally relaxed lower esophageal sphincter allows stomach acid to flow persistently into the esophagus.
This constant acid exposure transforms the esophagus's pink mucosal lining (stratified squamous epithelium) into a type of lining more...
