Recurrence Detection by Hybrid [F]FDG-PET in Advanced Head and Neck Squamous Cell Carcinoma.

Background: In the clinical management of advanced stage head and neck squamous cell carcinoma, the use of hybrid [F]FDG-PET imaging is well established. However, there is ongoing debate regarding the optimal frequency of hybrid PET scans to be included in follow-up protocols, particularly if the initial post-therapeutic scan is negative.

Methods: We conducted a single-center 10-year retrospective study involving all patients who underwent hybrid PET scans for the follow-up of advanced stage head and neck cancer.

The Swiss Paediatric Airway Cohort (SPAC).

Chronic respiratory symptoms, such as cough, wheeze and dyspnoea, are common in children; however, most research has, with the exception of a few large-scale clinical cohort studies, been performed in the general population or in small, highly-selected samples. The Swiss Paediatric Airway Cohort (SPAC) is a national, prospective clinical cohort of children and adolescents who visit physicians for recurrent conditions, such as wheeze and cough, and exercise-related respiratory problems. The SPAC is an observational study and baseline assessment includes standardised questionnaires for families and data extracted from hospital records, including results of clinically indicated investigations, diagnoses and treatments.

Functional evidence for continued alveolarisation in former preterms at school age?

Prematurity is the most common disruptor of lung development. The aim of our study was to examine the function of the more vulnerable peripheral airways in former preterm children by multiple-breath washout (MBW) measurements.86 school-aged children, born between 24 and 35 weeks of gestation and 49 term-born children performed nitrogen MBW.
