Purpose:
To describe the sonographic features of entesopathy in patients with psoriatic dactylitis. Materials and methods. Clinical, radiographic and sonographic evaluation of 120 hand joints with clinical abnormality including 20 fingers in 17 patients with rheumatoid arthritis (RA) and 20 fingers in 17 patients with psoriatic arthritis (PA).
Results:
Forty cases of dactylitis. In patients with RA: 29 cases of synovitis, 15 cases of tenosynovitis, and 2 cases of tendinitis; in patients with PA: 21 cases of synovitis and 3 cases of tenosynovitis. Bone erosions were present in RA patients whereas erosions with bone production were present in PA patients. A total of 60% of RA and PA patients showed erosions on conventional radiographs. Features suggesting entesopathy were present in PA patients only: specific changes of P3, capsular hyperostosis and periarticular periostitis.
Conclusion:
Based on evaluation of PA patients, it seems that sonographic features suggesting entesopathy in patients with dactylitis may be present.

Inflammatory Bowel Disease II: Crohn's Disease
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.

Assessment of the Abdomen I: Inspection and Auscultation
The abdominal examination is a cornerstone of clinical medicine, serving as a critical tool in diagnosing various gastrointestinal (GI) diseases. It involves a systematic approach that includes inspection and auscultation, each with distinct yet complementary roles in assessing the abdomen. This article will delve into these two primary methods healthcare professionals use to examine the abdomen.
Inspection of the Abdomen
The first step in any abdominal examination is inspection.
