Imaging Studies for Cardiovascular System VI: Calcium -Scoring CT

289
Calcium-Scoring CT ScanA calcium-scoring CT scan, also known as coronary artery calcium (CAC) scan, detects calcium deposits in the coronary arteries. This test assesses the risk of coronary artery disease (CAD), which can lead to cardiovascular events such as angina, heart failure, and sudden cardiac arrest.A calcium-scoring CT scan is generally recommended for individuals at intermediate risk of CAD without symptoms. It includes:Men aged 40-75 and women aged 50-75: Especially those with a...

Urinary Tract Calculi I: Introduction

334
Renal calculi, or kidney stones, are solid deposits of minerals and salts formed inside the kidneys. In medical terminology, "calculus" refers to the stone itself, while "lithiasis" describes the process of stone formation. Depending on their location within the urinary system, these stones may be classified as either urolithiasis, when situated within the urinary tract, or nephrolithiasis, when located within the kidneys. Each term signifies the specific impact of the stone.Predisposition...

Disorders of the Male Reproductive System

3.9K
Men's health issues are increasingly recognized as significant, with several conditions posing common threats. Among these, testicular cancer is especially prevalent in younger men, particularly those aged 20 to 35 years. The disease often manifests as a painless mass in the testicles, sometimes accompanied by a sensation of heaviness or a dull ache.
Prostate disorders are another major concern. These conditions can impair urinary flow due to the prostate's location around the urethra....

Area of Science:

  • Nephrology
  • Dermatology
  • Vascular Medicine

Background:

  • Calciphylaxis is a rare disorder causing skin necrosis due to vascular calcification and thrombosis.
  • Penile calciphylaxis, a rare manifestation, leads to severe tissue ischemia.

Purpose of the Study:

  • To identify risk factors, diagnostic methods, management strategies, and mortality associated with penile calciphylaxis.
  • To characterize the clinical course and outcomes of patients diagnosed with penile calciphylaxis.

Main Methods:

  • A retrospective review of 16 patients with penile calciphylaxis was conducted.
  • A control group of 44 male patients with non-penile calciphylaxis was included for comparison.

Main Results:

  • Patients with penile calciphylaxis had a median survival of 3.8 months, with 62.5% mortality at 6 months.
  • Risk factors identified include hyperparathyroidism and end-stage renal disease, with less obesity compared to controls.
  • A statistically significant difference in mortality was observed between penile calciphylaxis patients and controls (P = .008).

Conclusions:

  • Penile calciphylaxis is associated with high mortality, underscoring the need for prompt recognition and intervention.
  • End-stage renal disease, hyperparathyroidism, and a normal body mass index are identified as key risk factors.
  • Further research may explore the utility of imaging in diagnosing penile calciphylaxis.
