Abstract

Insights

Magnetic resonance imaging (MRI) reveals key features of psoriatic arthritis in hand joints, including early signs like enthesitis and bone edema, progressing to joint damage and fusion in later stages.

Area of Science:

  • Rheumatology
  • Radiology
  • Orthopedics

Background:

  • Psoriatic arthritis (PsA) is a chronic inflammatory disease affecting joints and entheses.
  • Hand joint involvement is common in PsA, impacting function and quality of life.
  • Accurate diagnosis and monitoring of PsA progression are crucial.

Purpose of the Study:

  • To review the spectrum of morphologic and functional MRI findings in psoriatic arthritis of the hand joints.
  • To correlate MRI findings with disease stage and activity.
  • To enhance understanding of PsA pathophysiology through imaging.

Main Methods:

  • Review of existing literature on MRI in psoriatic arthritis of the hand.
  • Analysis of morphologic and functional MRI sequences.
  • Correlation of imaging findings with clinical presentation and disease progression.

Main Results:

  • Early-stage MRI findings include enthesitis, bone marrow edema, and periostitis.
  • Articular or flexor tendon sheath synovitis is frequently observed in early PsA.
  • Late-stage findings encompass destructive and proliferative bony changes, subluxation, and ankylosis.

Conclusions:

  • MRI is a valuable tool for diagnosing and staging psoriatic arthritis in the hands.
  • Characteristic MRI findings reflect the inflammatory and destructive processes in PsA.
  • Understanding the MRI spectrum aids in patient management and treatment strategies.

Genome-wide Association Studies-GWAS

Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
GWAS does not require the identification of the target gene involved in...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation

Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...
