まとめ
毒性メガコロン (TM) を患った小児科の患者は,リバイティング・ループ・イレオストミーによる解消を達成しました. このアプローチは,小児TMの治療に用いるコレクトミーの代替手段として,特に遠隔結腸不動症の治療に用いる.
科学分野:
- 小児胃腸内科 小児胃腸内科
- 結腸直腸外科手術について
背景:
- 毒性大腸 (TM) は,大腸炎症の希少だが深刻な合併症である.
- 標準的な治療には,しばしば全腹腔大腸切除術と末端大腸切除術が含まれるが,これは小児患者では病的な症状になる可能性がある.
研究 の 目的:
- 小児の有毒メガコロンの代替外科的管理として,ダイバーティング・ループ・イレオストミーの有効性を評価する.
- 子どもにおけるTMの根本的な原因の診断における大腸運動性研究の役割を評価する.
主な方法:
- 14歳の男性に有毒メガコロンが発症した症例報告.
- 診断作業には,便培養,直腸バイオプシー,直腸マノメトリー,大腸運動性研究が含まれていました.
- 手術の介入は,回転ループのイレオストミーによるものでした.
主要な成果:
- 診断検査では,感染症の原因 (Clostridium difficile) や構造的異常 (ヒルシュプルング病,門アハラシア) を排除した.
- 大腸の運動性に関する研究では,慢性的な便秘とエンコープレシスに一致する遠大腸の運動不活性が明らかになりました.
- 患者の有毒なメガコロンは,転向ループ・イレオストミーにより解消され,完全な腹腔切除術を避けました.
結論:
- ディバーティング・ループ・イレオストミーは,小児の有毒性メガコロンの管理のために,全腹腔コレクトミーの有効な代替手段である可能性があります.
- 先発性大腸内溶液は,付随する大腸不動性の管理において,イレオストミーに価値のある付属体である可能性があります.
- このアプローチは,標準的なコレクトミーと比較して,小児患者の罹患率を減らす可能性があります.

Pharmaceutical Poisoning: Treatment Strategies
17
Treatment strategies for poisoning are a critical aspect of emergency medicine, focusing on preventing the absorption of toxins and enhancing their elimination. When a poisoning incident occurs, the first response is to halt exposure and decontaminate the patient, particularly through gastrointestinal (GI) methods if the poison was ingested.Gastrointestinal Decontamination Techniques:Activated charcoal is the cornerstone of GI decontamination. It works through adsorption, binding the toxin to...

Drugs for Treatment of Ulcerative Colitis in IBD
544
Ulcerative colitis is a chronic inflammatory condition primarily affecting the colon and rectum. The primary drugs used in the treatment of ulcerative colitis are aminosalicylates. They exhibit anti-inflammatory and immunosuppressive properties. They modulate inflammatory mediators and inhibit the activity of nuclear factor κB (NF-κB). Aminosalicylates also reduce inflammation by inhibiting prostaglandin and leukotriene production and decreasing neutrophil chemotaxis and superoxide...

Upon diagnosis, managing Inflammatory Bowel Disease (IBD) involves addressing several crucial aspects. The primary goals include resting the bowel, correcting malnutrition, and providing symptomatic relief. Resting the bowel may consist of medications to reduce inflammation and promote healing. Correcting malnutrition is essential, often requiring dietary adjustments and nutritional supplements. Symptomatic relief aims to ease pain, diarrhea, and other discomforts in IBD.

Drugs for Treatment of Diarrhea-Predominant IBS
754
Diarrhea-predominant irritable bowel syndrome (IBS-D) is a subtype of IBS characterized primarily by frequent, loose, or watery stools, abdominal pain, and abdominal discomfort. Therapeutic approaches to managing IBS-D include dietary changes, stress management techniques, and pharmaceutical interventions.
Two specific drugs used in the treatment are alosetron (Lotronex) and eluxadoline (Viberzi). Alosetron, a 5-HT3 antagonist, works by slowing the movement of stools in the gut, reducing bowel...

Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...
