The structure and function of DNA
DNA structure and replication Genetic information within multicellular organisms, including man, is stored in molecules of deoxyribonucleic acid (DNA), which reside within the chromosomes of each cell nucleus. A DNA molecule consists of two very long chains, or strands, of...Head and neck cancer and PET-CT
Positron emission tomography-computed tomography (PET-CT) is an imaging technique in which abnormalities of tissue metabolism are precisely superimposed onto the anatomy. It relies on the premise that malignant cells are more metabolically active compared with non-malignant cells. On this basis,...From patient to performer
Peter Cawrey lives in Harpenden, Hertfordshire, with his wife Dorothy. He had a salvage laryngectomy for squamous cell carcinoma in 2015, three years following his initial radiotherapy. Due to complications and a complex recovery, he has elected not to have...
Smoking causes cancer – so what’s new?
You may well ask what is the novel value of a paper looking at smoking habits in patients with confirmed head and neck squamous cell carcinoma (HNSCC), but this paper highlights some pertinent points for clinical practice in the current...Chronic rhinosinusitis management: back to the future?
Immunology is a dim and distant medical school memory to many ENT surgeons, but the increasingly complex immunology of chronic rhinosinusitis is fascinating (honestly!). Medical management options in CRS no longer just involves saline and steroids, and we need to...
Lymph node ratio in tongue cancer
This is an analysis of 88 patients treated in Switzerland between 2003 and 2012. All patients had a selective neck dissection and recurrence occurred in 25 patients. Overall and disease specific survival were 72% and 80%. They specifically looked at...
When should we decompress the facial nerve in Bell’s Palsy?
It has been over three decades since Fisch popularised facial nerve (FN) decompression for Bell’s Palsy. Studies further exploring this have been few since, partly due to the major complications that can occur following this type of surgery. The current...
Novel method for determining BCC margins
This correspondence describes a new technique for determining basal cell carcinoma (BCC) borders, to aid in obtaining clear peripheral resection margins. Whilst this can be straightforward in small well-defined nodular BCCs, some BCC subtypes are ill-defined or morphoeic, and resection...
Benefits of combined antiviral and corticosteroid therapy in Bell’s palsy and the role of decompression surgery
Early use of steroids has been established as standard management in Bell’s palsy but simultaneous use of antiviral agents has variable acceptance. This review article analyses statistically based evidence to settle the issue. High quality evidence from a 2009 Cochrane...Prednisolone and/or acyclovir for Bell’s palsy
Landmark Paper: Sullivan FM, Swan IRC, Donnan PT, et al. Early treatment with prednisolone or acyclovir in Bell’s Palsy. N Engl J Med 2007;357(16):1598-607. Facial nerve paralysis as a consequence of Bell’s palsy can result in devastating long-term effects on...
Margin control using optical techniques in head and neck surgery
Emerging optical techniques such as high-resolution microendoscopy (HRME) are currently being examined for their reliability in discriminating benign from neoplastic epithelium. These techniques may offer the potential to detect the margin of an upper aerodigestive tract tumour in a non-invasive...
