Test performance of PET-CT for mediastinal lymph node staging of pulmonary carcinoid tumours.

Positron emission tomography-CT (PET-CT) is one of the initial mediastinal staging modality for non-small cell lung cancer; however, the clinical utility in carcinoid tumours is uncertain. We sought to determine the test performance of PET-CT for mediastinal lymph node staging of pulmonary carcinoid tumours. We collated data from seven institutions, performing a retrospective search on pathological databases for a consecutive series of patients who underwent thoracic surgery (with lymph nodal dissection) for carcinoid tumours with preoperative PET-CT staging.

Do British commercial mountaineering expeditions carry drugs to treat high altitude illnesses?

High altitude commercial expeditions are increasingly popular. As high altitude illnesses are common on ascent to altitude, this study aimed to ascertain whether medications for these conditions were carried by commercial operators who run high altitude expeditions. Despite recommendations, it appears that drugs to treat high altitude illnesses are not routinely carried by commercial operators.
