Concurrent chemotherapy with radiotherapy is the standard treatment for locoregionally advanced nasopharyngeal cancer. Cetuximab can be used in the treatment of head and neck squamous cell carcinoma. However, the randomised studies that led to approval for its use in this setting excluded nasopharyngeal cancer. In the context of limited data for the use of cetuximab in nasopharyngeal cancer in the medical literature, this review aimed to summarise the current evidence for its use in both primary and recurrent or metastatic disease.
A literature search was performed using the keywords ‘nasopharyngeal neoplasm’, ‘cetuximab’ and ‘Erbitux’.
Twenty studies were included. There were no randomised phase III trials, but there were nine phase II trials. The use of cetuximab in the treatment of nasopharyngeal carcinoma has been tested in various settings, including in combination with induction chemotherapy and concurrent chemoradiotherapy, and in the palliative setting.
There is no evidence of benefit from the addition of cetuximab to standard management protocols, and there is some evidence of increased toxicity. There is more promise for its use in metastatic or locally recurrent settings. This review draws together the existing evidence and could provide a focus for future studies.
Evidence from the literature shows that clinicians’ knowledge of rules and legislation surrounding driving can often be poor. A closed-loop audit was conducted to gauge the level of driving advice given to patients with dizziness.
The clinical notes of 100 patients referred to the vertigo clinic at a tertiary referral centre were retrospectively searched for evidence of driving advice. Education sessions were undertaken and a patient information leaflet was developed before a second cycle of the audit.
Results and conclusion
The proportion of patients having documented evidence of receiving driving advice increased from 6.3 per cent to 10.4 per cent. It is therefore clear that, despite this improvement, a significant proportion of patients’ notes did not contain documentation about driving. This is likely because of many reasons, including individual interpretation by clinicians. This paper provides a reminder of the rules, and discusses their interpretation and implementation in an increasingly medicolegal environment.
To verify the previously untested assumption that eating more salad enhances vegetable intake and determine if salad consumption is in fact associated with higher vegetable intake and greater adherence to the Dietary Guidelines for Americans (DGA) recommendations.
Individuals were classified as salad reporters or non-reporters based upon whether they consumed a salad composed primarily of raw vegetables on the intake day. Regression analyses were applied to calculate adjusted estimates of food group intakes and assess the likelihood of meeting Healthy US-Style Food Pattern recommendations by salad reporting status.
Cross-sectional analysis of data collected in 2011–2014 in What We Eat in America, the dietary intake component of the National Health and Nutrition Examination Survey.
US adults (n 9678) aged ≥20 years (excluding pregnant and lactating women).
On the intake day, 23 % of adults ate salad. The proportion of individuals reporting salad varied by sex, age, race, income, education and smoking status (P<0·001). Compared with non-reporters, salad reporters consumed significantly larger quantities of vegetables (total, dark green, red/orange and other), which translated into a two- to threefold greater likelihood of meeting recommendations for these food groups. More modest associations were observed between salad consumption and differences in intake and likelihood of meeting recommendations for protein foods (total and seafood), oils and refined grains.
Study results confirm the DGA message that incorporating more salads in the diet is one effective strategy (among others, such as eating more cooked vegetables) to augment vegetable consumption and adherence to dietary recommendations concerning vegetables.
This innovative, introductory text is authored by key subject leaders in clinical neuroendocrinology with decades of research and teaching experience. Addressing the need for a concise description of human neuroendocrine systems, this important review of various significant basic science advances is relevant for all levels of experience. An indispensable resource for a variety of learners, this book will also enable biomedical science graduate students to extend their knowledge using its valuable clinical context. Beautifully illustrated, this text integrates basic scientific principles with clinical cases and includes several illustrated imaging studies, and in-depth discussions of basic principles and their interpretations. Extensive reference lists of clinical papers, teaching resources and a selection of review questions are included with each chapter, emphasizing the real-life importance of basic neuroendocrine principles in human health and disease. Clinical reviews are included to provide convenient links to more specialized texts, ensuring a successful springboard for learners worldwide.
