A breath test for malignant mesothelioma using an electronic nose.

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 ...

The alcohol breath test--a review.

The alcohol breath test (ABT) is evaluated for variability in response to changes in physiological parameters. The ABT was originally developed in the 1950s, at a time when understanding of pulmonary physiology was quite limited. Over the past decade, physiological studies have shown that alcohol is exchanged entirely within the conducting airways via diffusion from the bronchial circulation. T...

Breath Test for Assessing the Disease Activity

Few clinical studies have so far focused on gastrointestinal motility in patients with eosinophilic gastroenteritis. A 29-year-old man was evaluated for epigastralgia of unknown origin. A histopathological examination of biopsy specimens from the duodenum revealed numerous eosinophilic infiltrations. Eosinophilic enteritis was therefore diagnosed. The patient received oral prednisolone and his ...
