Do value of high-frequency miniprobes and conventional radial endoscopic ultrasound in the staging of early Barrett 's carcinoma?
HFPs are significantly superior to crEUS for local staging of Barrett's cancer. However, the accuracy of assessment of the T category was unsatisfactory with both techniques.
The data serendipitously indicate an alternative hypothesis - that winter excess morbidity is a feature of health benefits derived in the summer and differentially available to the more affluent, such as opportunities for outdoor leisure. This hypothesis deserves testing in a study designed for that purpose, although it is not entirely satisfactory as an explanation of existing data.
