Introduction SARCOMAS occur infrequently in the nose and throat so that the number which pass through any individual surgeon's practice tends to be small. As a consequence the description of these tumours in textbooks on diseases of the ear, nose and throat, and malignant lymphomas in particular, has been almost uniformly sketchy, and their pathological features virtually neglected. Sarcomas ar...

Rapid and portable diagnosis of pathogenic bacteria can save lives lost from infectious diseases. Biosensors based on a "chemical nose" approach are attracting interest because they are versatile but the governing interactions between bacteria and the biosensors are poorly understood. Here, we use a "chemical nose" biosensor based on gold nanoparticles to explore the role of extracellular polym...

BACKGROUND The electronic nose (e nose) provides distinctive breath fingerprints for selected respiratory diseases. Both reproducibility and respiratory function correlates of breath fingerprint are poorly known. OBJECTIVES To measure reproducibility of breath fingerprints and to assess their correlates among respiratory function indexes in elderly healthy and COPD subjects. METHOD 25 subje...

Cutaneous leishmaniasis(CL) is referred to a group of diseases because of the varied clinical presentation, ranging from small cutaneous nodule to wide spread mucosal destruction. The nose is rarely involved by CL in even in endemic region. In this report we describe a rare rhinophymatous presentation of CL from a non-endemic region which was diagnosed by fine needle sampling and treated with M...

OBJECTIVE To investigate whether exhaled breath analysis using an electronic nose can identify differences between inflammatory joint diseases and healthy controls. METHODS In a cross-sectional study, the exhaled breath of 21 rheumatoid arthritis (RA) and 18 psoriatic arthritis (PsA) patients with active disease was compared to 21 healthy controls using an electronic nose (Cyranose 320; Smith...

Malignant mesothelioma (MM) is a rare tumour which is difficult to diagnose in its early stages. Earlier detection of MM could potentially improve survival. Exhaled breath sampling of volatile organic compounds (VOCs) using a carbon polymer array (CPA) electronic nose recognises specific breath profiles characteristic of different diseases, and can distinguish between patients with lung cancer ...
