Diseases of the Liver and Gallbladder

965
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not...

Inflammatory Bowel Disease I: Ulcerative Colitis

316
Introduction
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...

Nephrotic Syndrome I : Introduction

27
Nephrotic Syndrome is a chronic kidney disorder defined by clinical findings such as severe proteinuria, hypoalbuminemia, hyperlipidemia, and edema. These symptoms result from damage to the glomeruli, the kidney’s filtering units, increasing their permeability to proteins.Definition and Meaning:Proteinuria, defined as the loss of more than 3.5 grams of protein per day in adults, is a crucial feature of nephrotic syndrome. This condition is often accompanied by edema, the accumulation of...

Chronic Pancreatitis I: Introduction

148
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Gallbladder01:17

Gallbladder

896
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins...

科学分野:

  • 病理学について
  • 医療診断
  • プロテオミクス

背景:

  • アミロイドーシスは,誤った折りたたまれたタンパク質の細胞外沈殿によって特徴づけられる全身疾患である.
  • アミロイドーシスの Gallbladderの関与は広く認識されず,診断の遅延につながる可能性があります.

研究 の 目的:

  • 胆管アミロイドーシスの症例の大群を分析する
  • 胆管アミロイドーシスの臨床的および形態学的特徴を特定する.
  • 胆管のアミロイドの種類と発生率を決定する.

主な方法:

  • 2008年から2023年の間に分析された118のコレシステクトミー標本の遡及的レビュー.
  • アミロイド型にはプロテオミクスを用いた技術が用いられました.
  • 臨床的および形態学的特徴を評価した.

主要な成果:

  • トランスチレチンアミロイド症 (ATTR) と軽鎖アミロイド症 (AL) が最も一般的であった.
  • アミロイドーシスは,臨床情報のある患者の半数で予期せぬ診断でした.
  • 形態学的に見直されたすべての症例で周周血管の関与が観察されました.
  • フォローアップしたすべての患者は全身疾患の証拠を示した.

結論:

  • 胆管アミロイドーシスはしばしば予期せぬ発見であり,全身疾患の初期症状である可能性があります.
  • コレチステクトミーサンプル,特に周回筋血管の注意深い検査は極めて重要です.
  • 迅速なアミロイド型決定は,特に高齢の患者では,診断の遅延を防止し,管理を改善することができます.
