Visible light-induced healing of diabetic or venous foot ulcers: a placebo-controlled double-blind study.

Background And Objectives: Non-healing ulcers represent a significant dermatological problem. Recently, conventional therapy-resistant chronic ulcers have been treated with low energy lasers or light-emitting diodes in the visible and near IR region, but only a few placebo-controlled double-blind studies have been performed to support the efficacy of this approach. The aim of the present study was to evaluate the efficacy of a broadband (400-800  nm) visible light device in the treatment of leg or foot ulcers.

Wireless capsule video endoscopy is a superior diagnostic tool in comparison to barium follow-through and computerized tomography in patients with suspected Crohn's disease.

Background: The recently introduced wireless M2A capsule video endoscopy (CVE) has been demonstrated to be superior to barium follow-through and enteroscopy in diagnosing patients with occult blood loss and iron-deficiency anaemia.

Objective: To further investigate CVE in comparison to barium follow-through and entero-computerized tomography (CT) in establishing the diagnosis of patients with suspected Crohn's disease.

Design And Setting: The study was conducted in one academic hospital.

Initial experience of wireless-capsule endoscopy for evaluating occult gastrointestinal bleeding and suspected small bowel pathology.

Objective: Small bowel pathology can be diagnosed using enteroscopy (which has limitations) and by x-ray (which is not sensitive for flat lesions). For the first time ever, we used a new technique, wireless-capsule video endoscopy, to diagnose small bowel pathology. Our aim was to prove the effectiveness and safety of this technology.
