The Christie score for post-treatment response assessment PET/CT in patients with head and neck squamous cell carcinoma: a safe and simple scoring system.

Background: Radiotherapy with or without concurrent chemotherapy is a standard of care treatment for patients with head and neck squamous cell carcinoma (HNSCC). Upon completion, patients are referred for a post-treatment F-FDG PET/CT (Fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography) scan to help guide ongoing management by assessing for the presence or absence of residual or recurrent disease and differentiating this from post-treatment inflammation. To improve objective reporting of response, we developed the Christie score.

Role of complementary Ct chest in patients presenting with acute abdominal symptoms during covid-19 pandemic: a UK experience.

Background: In March 2020, the UK Intercollegiate General Surgery Guidance on COVID-19 recommended that patients undergoing emergency abdominal CT should have a complementary CT chest for COVID-19 screening.

Purpose: To establish if complementary CT chest was performed as recommended, and if CT chest influenced surgical intervention decision. To assess detection rate of COVID-19 on CT and its correlation with RT-PCR swab results.

Efficacy of an amine fluoride-triclosan mouthrinse as compared to the individual active ingredients.

Background: The purpose of the clinical study was to examine the antibacterial and plaque-reducing properties of mouthrinses containing triclosan (TRI), amine fluoride (AmF), and the combination of both (AFT) on 4-day plaque regrowth. A placebo solution (PLA) and a 0.2% chlorhexidine solution (CHX) served as negative and positive controls, respectively.
