International Archives of Allergy and Immunology, 2010 Sensitivity to strong odors has a broad differential diagnosis. A presentation is made of a 60-year-old man with lifelong mild allergic rhinitis and a superimposed 4-year history of sensitivity to smells. He had no response to medical treatments or allergic immunotherapy. His physical examination was unremarkable.

Separation-based model for low-dose CT image denoising
The Journal of Engineering, 2020 Low-dose computed tomography (LDCT) image often contains mottle noise and streak artefacts, which seriously interfere with clinical diagnosis. In this study, the separation-based (SEPB) method is proposed for mottle noise and streak artefacts suppression
