[Ultrasound features of entesopathy in patients with psoriatic dactylitis]. / Signes échographiques d'enthésopathies au cours des dactylites psoriasiques.

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.

[Malaise with sweating induced by eye-drop. A case of iatrogenic pathology caused by diagnostic error]. / Malaises avec sueurs dus à un collyre. Un cas d'errance diagnostique due à une pathologie iatrogène.

INTRODUCTION: Eye-drops can provoke various systemic side effects and diagnosis of an iatrogenic pathology can made difficult. Observation For 4 months, and 80 year-old man had experienced severe recurrent episodes of sweating concomitant with shaking of the legs. Alpha stimulating eye-drops, prescribed for his glaucoma, were at the origin of these problems. On withdrawal of the latter, the symptoms regressed. DISCUSSION: Diagnosis of an iatrogenic pathology was made after 3 months of medical explorations. The delay in diagnosis was prolonged because the patient had not mentioned the use of an active ingredient, since it was in the form of eye-drops. CONCLUSION: The search for drug-induced causes must be systematic when faced with any unexplained symptom and must include all the active ingredients, whatever their form of administration.
