Stratifying risk of malignancy in cystic lateral neck lumps: a multivariant analysis of demographic, radiological and histological investigation factors and the development of a patient-centred risk-predictive tool for malignancy.

Background: Management of lateral cystic neck masses with no apparent upper aerodigestive tract primary tumour in adults is controversial. Imaging modalities and fine needle aspiration cytology often struggle to distinguish the presence of malignancy.

Method: This study entailed a multicentre retrospective review of all patients with isolated lateral cystic neck masses from 2012 to 2018 in three Welsh health boards, utilising demographic data and first-line investigations (ultrasound scanning and fine needle aspiration cytology) to develop an evidence-based predictive tool for risk of malignancy.

Direct reprogramming of human fibroblasts into insulin-producing cells using transcription factors.

Direct lineage reprogramming of one somatic cell into another without transitioning through a progenitor stage has emerged as a strategy to generate clinically relevant cell types. One cell type of interest is the pancreatic insulin-producing β cell whose loss and/or dysfunction leads to diabetes. To date it has been possible to create β-like cells from related endodermal cell types by forcing the expression of developmental transcription factors, but not from more distant cell lineages like fibroblasts.

Endoscopic stapler versus laser diverticulotomy for Zenker's diverticulum: a systematic review and meta-analysis.

Objective: A literature review and meta-analysis was performed to assess for difference in rate of complications and need for revision surgery between endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy. The hypothesis was that endoscopic stapler-assisted diverticulotomy has a lower complication rate but endoscopic carbon dioxide laser diverticulotomy has a lower need for revision surgery.

Method: This was a systematic review of English-language studies comparing endoscopic stapler-assisted diverticulotomy and endoscopic carbon dioxide laser diverticulotomy for the treatment of Zenker's diverticulum.

Hypocalcaemia following laryngectomy: prevalence and risk factors.

Objectives: To establish the prevalence of hypocalcaemia following laryngectomy and demonstrate that total thyroidectomy is a risk factor.

Methods: A retrospective cohort study was conducted that included all patients who underwent total laryngectomy from 1st January 2006 to 1st August 2017. Exclusion criteria were: pre-operative calcium derangement, previous thyroid or parathyroid surgery, concurrent glossectomy, pharyngectomy, or oesophagectomy.

Efficacy and safety of fluocinolone acetonide 0.025% otic solution in patients with otic eczema: a randomized, double-blind, placebo-controlled clinical trial.

Objectives To assess the efficacy and safety of fluocinolone acetonide 0.025% otic solution versus placebo in treating patients with otic eczema. Methods In this multicentre, randomized, double-blind, parallel-group phase 3 clinical trial, conducted at 12 Spanish centres between March 2012 and March 2013, patients received fluocinolone acetonide 0.
