Background/aims: To validate the effectiveness of a newly developed light-emitting diode (LED)-narrow band imaging (NBI) system for detecting early malignant tumors in the oral cavity.
Methods: Six men (mean age, 51.5 years) with early oral mucosa lesions were screened using both the conventional white light and LED-NBI systems.
Background: Auricular tophi are firm deposits of monosodium urate in crystal form, which may slowly develop in subcutaneous tissue of the ear. Ear is not usual locations for gout tophi, but when this growth does occur, helix and the antihelix are common sites.
Case Presentation: We present a 64-year-old man who had multiple painless nodules over bilateral helix.
Objective: Satisfaction with amplification in daily life (SADL) may quantify satisfaction with hearing aids. We translated and validated a Chinese version of SADL (CSADL).
Design: The SADL was translated from English to Mandarin Chinese by two bilingual physicians.
