Cholecystitis01:20

Cholecystitis

Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
Cholesterol: Significance and Regulation01:29

Cholesterol: Significance and Regulation

Although not a source of energy, cholesterol plays a significant role as a foundational structure for bile salts, steroid hormones, and vitamin D, as well as being a crucial component of plasma membranes. Approximately 15% of blood cholesterol is derived from our diet, with the remainder synthesized from acetyl CoA by the liver and intestines. Cholesterol is eliminated from the body through its conversion into bile salts, which are eventually discarded in the feces.
Considering cholesterol and...
Esophageal Varices-II: Clinical Features and Management01:28

Esophageal Varices-II: Clinical Features and Management

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.
In the initial assessment, a thorough review of the patient's medical history is vital to identify risk factors such as liver disease, alcohol abuse, or...

Area of Science:

  • Vascular Surgery
  • Nephrology
  • Dermatology

Background:

  • An 81-year-old woman with chronic kidney disease and hypertension underwent endovascular repair for an abdominal aortic aneurysm.
  • Post-procedure complications included calf pain, altered mental status, and worsening kidney function.

Observation:

  • Symmetrical purpuric macules and reticulated skin lesions appeared on the third post-operative day.
  • Melena developed on the seventh post-operative day, indicating gastrointestinal bleeding.

Findings:

  • Skin biopsy confirmed cutaneous cholesterol embolization syndrome (CES).
  • The patient presented with a constellation of systemic and cutaneous manifestations of cholesterol crystal embolization.

Implications:

  • Early recognition and supportive management, including hemodialysis, are crucial for CES recovery.
  • This case underscores the risk of CES following endovascular procedures involving atherosclerotic aorta.
