Skin Diseases and Disorders

3.8K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Inflammatory Bowel Disease II: Crohn's Disease

227
Introduction
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Area of Science:

  • Rheumatology
  • Dermatology
  • Radiology

Background:

  • Psoriatic dactylitis is an inflammatory condition affecting the digits.
  • Onychodystrophy is a common manifestation of psoriatic arthritis.
  • Accurate assessment of nail involvement is crucial for effective management.

Purpose of the Study:

  • To evaluate the utility of magnetic resonance imaging (MRI) and ultrasound in assessing onychodystrophy in psoriatic dactylitis.
  • To correlate imaging findings with active inflammation.

Main Methods:

  • Utilized MRI and ultrasound to examine nail structures in patients with psoriatic dactylitis.
  • Assessed nail bed thickening, matrix changes, and vascularity.
  • Correlated imaging findings with clinical signs of inflammation.

Main Results:

  • MRI and ultrasound demonstrated nail bed thickening and matrix abnormalities.
  • Increased vascularity was observed, indicative of active inflammation.
  • Imaging findings correlated with the extent of onychodystrophy.

Conclusions:

  • Magnetic resonance imaging (MRI) and ultrasound are valuable tools for assessing the extent of onychodystrophy in psoriatic dactylitis.
  • These modalities can identify key features of active inflammation within the nail unit.
  • Findings support the use of MRI and ultrasound in the comprehensive evaluation of psoriatic dactylitis.
