OBJECTIVE To study the characteristics of peptic ulcer and erosion in pediatric patients. METHODS Over a period of seven years, 1,026 children underwent upper gastrointestinal endoscopy in our pediatric gastroenterology unit. RESULTS Peptic ulcers and erosions were found in 59 (7.2%) patients [ulcers in 42 (5.1%)and erosions in 17 (2.1%)]. Thirty (50.9%) children presented with acute upper ...

If A and K are compact convex sets in Rn, a Steiner-type formula is valid for the erosion of A by K if and only if A is open with respect to K. The if part is proved in the general case. The only if part is conjectured, and proved only in the case n = 2.

OBJECTIVE Characterize the phenotypic features of media and intima coronary artery smooth muscle cells (SMCs) in mildly stenotic plaques, erosions, stable plaques, and in-stent restenosis. METHODS AND RESULTS Expression of alpha-smooth muscle actin (alpha-SMA), smooth muscle myosin heavy chains (SMMHCs), and smoothelin was investigated by immunohistochemistry followed by morphometric quantifi...

INTRODUCTION Erosions of the sacroiliac joints (SIJ) on pelvic radiographs of patients with ankylosing spondylitis (AS) are an important feature of the modified New York classification criteria. However, radiographic SIJ erosions are often difficult to identify. Recent studies have shown that erosions can be detected also on magnetic resonance imaging (MRI) of the SIJ early in the disease cours...

OBJECTIVE The objective of this study was to determine the prevalence and distribution of bone erosions detectable by US in patients with early RA (ERA) in comparison with long-standing RA (LSRA), other erosive diseases and healthy controls. METHODS Thirty patients with ERA and 80 patients with LSRA were consecutively recruited. Thirty patients with PsA, 15 with primary OA, 10 with gout and 2...

OBJECTIVE To compare a low field dedicated extremity magnetic resonance imaging system (E-MRI) with x ray and clinical examination, in the detection of inflammation and erosive lesions in wrist and metacarpophalangeal (MCP) joints in newly diagnosed, untreated rheumatoid arthritis (RA). PATIENTS AND METHODS Twenty five patients (disease duration < or =1 year) and three healthy controls entere...

Reports on healing of erosions in rheumatoid arthritis are rare. However, it is expected that repair of erosions should be seen more often during the period of extensive use of disease modifying antirheumatic drugs, especially in patients who experience sustained remission. Two such cases are described.

OBJECTIVES The RANK/RANKL/osteoprotegerin (OPG) system plays a central role in the pathogenesis of bone erosions in rheumatoid arthritis (RA). The aim of this study was to test the association between 11 single-nucleotide polymorphisms (SNPs) located on RANK, RANKL and OPG genes and anticitrullinated peptide antibody (ACPA) presence or erosions in RA. METHODS PATIENTS This work was perform...

In several areas of the Alps, steep grassland is characterized by shallow erosions. These erosions represent a hazard through the increased availability of unconsolidated material in steep locations, loss of soil and impaired landscape aesthetics. Generally, the erosions concern only small areas but sometimes occur in large numbers. Remote sensing technologies have emerged as suitable tools to ...
