Objective: This study analyses outcomes for 660 patients managed via a novel telescopic pathway for suspected head and neck cancer referrals.

Method: Data were collected prospectively between January 2021 and December 2022, capturing all two-week-wait referrals triaged as low risk and managed via a nurse-led clinic for nasendoscopic examination and consultant-led remote assessment.

Results: In total, 660 patients were included.

Purpose: This study aims to gain in-depth feedback on patient perceptions of remote assessment in otology, to better inform the development of a telemedicine pathway for new otology referrals.

Methods: A qualitative descriptive approach was employed to analyse semi-structured interviews from 14 patients seen in a routine otology clinic.

Results: Patients were generally accepting of the proposed telemedicine pathway.

Purpose: To compare outcomes of telephone and face-to-face consultations for new otology referrals and discuss the wider use of telemedicine in otology.

Methods: Retrospective cohort study including new adult otology referrals to our unit, sampled consecutively between March 2021 and May 2021, seen in either a face-to-face or telephone clinic. Primary outcome measure was the proportion of patients with a definitive management outcome (discharged or added to waiting list for treatment) versus the proportion of patients requiring follow-up for further assessment or review.

Objectives: This study summarizes the introduction of a novel telescopic pathway, which streamlines 2-week-wait suspected head and neck cancer referrals to our unit, describes the logistics of the pathway, and analyzes referral numbers and outcomes. We also discuss wider issues surrounding remote assessment in head and neck cancer.

Methods: Data were collected prospectively between January and May 2021, capturing all 2-week-wait referrals to our unit following the introduction of a telescopic pathway which utilized a nurse-led clinic for nasendoscopic examination of selected patients and consultant-led remote assessment using store and forward technology.

Background: We present our 9-year consecutive case series of skull base chordomas and chondrosarcomas from a UK tertiary referral centre, discussing treatments offered and outcomes. This was carried out to improve understanding around current treatment and to better inform the management of future patients.

Methods: Consecutive case series over a 9-year period (2007-2016).

Purpose: This systematic review describes and evaluates the current literature on remote otological assessment using video-otoscopy with regards to reliability and potential applications.

Methods: Systematic review was conducted in accordance with the PRISMA statement. There was heterogeneity of included studies, so a descriptive analysis was undertaken.

Introduction In 2017, Cheshire and Merseyside Local Dental Network introduced an Oral Cancer Care Guide for dental teams, emphasising the importance of early detection, appropriate referral, and effective patient communication. This study looks at the effect on two-week-wait (TWW) referrals to one unit, following the introduction of the guide and regional educational intervention.Methods Somerset Cancer Register, provided data from two three-month cohorts of TWW suspected head and neck cancer referrals, before and after introduction of the guide.

Objectives: While uncommon in the population at large, peritonsillar abscess (PTA) is a common subject of ENT referrals. Missed or uncertain diagnosis is a source of concern for non-specialist referrers. In line with the NHS England Second Sepsis Action Plan, we aimed to develop a predictive score for the presence of PTA.

Lycopene and green tea consumption have been observationally associated with reduced prostate cancer risk, but the underlying mechanisms have not been fully elucidated. We investigated the effect of factorial randomisation to a 6-month lycopene and green tea dietary advice or supplementation intervention on 159 serum metabolite measures in 128 men with raised PSA levels (but prostate cancer-free), analysed by intention-to-treat. The causal effects of metabolites modified by the intervention on prostate cancer risk were then assessed by Mendelian randomisation, using summary statistics from 44,825 prostate cancer cases and 27,904 controls.

Coblation is one of the more recent techniques for tonsillectomy; however, it remains unclear whether it exhibits any benefit or increased risk when compared to other techniques. This review provides an updated assessment of coblation tonsillectomy and how it compares to other tonsillectomy techniques. Systematic review and descriptive analysis of published literature.

Background: Ear disease in Nepal is a common problem which, left untreated, can cause serious complications such as hearing impairment (HI). Evidence shows that HI is associated with educational difficulties, employment problems and social isolation. Currently, there is little qualitative literature investigating the long-term impact of ear disease, and none specifically reporting on Nepali populations.

Aim: To consider the financial benefit to the authors' trust of omitting a preoperative group and save in enhanced recovery arthroplasty patients, and to estimate the scope for national savings. Patient safety was considered to determine acceptability for routine practice.

Methods: A total of 121 patients receiving a total knee replacement or total hip replacement on the authors' enhanced recovery protocol were selected.

Aims: There is increasing evidence of Gleason score (GS) drift in prostatic core biopsies during the last two decades. The ProtecT study is a randomized controlled study and provides an excellent cohort to study the effect of time, prostate-specific antigen (PSA) level, perineural invasion, tumour length and age on GS.

Methods And Results: The ProtecT study recruited men in the United Kingdom between 1999 and 2010.

Article Synopsis
  • Functional outcomes like swallowing, chewing, speech, and saliva are crucial for cancer patients, influencing their treatment strategies, especially in head and neck cancers.
  • The study involved 1614 patients with cancer in areas such as the oral cavity, oropharynx, and larynx, analyzing how the importance of these functions changes from early to late-stage cancers.
  • Results showed that while the importance of these functions remained steady among clinical groups, the specific priorities varied: swallowing and speech gained significance in advanced tumours, highlighting the need for treatments that support these essential functions after therapy.

Evidence for the effectiveness of psychological therapies for people who self-harm is limited. Personal construct theory provides a model of self-harm and a framework for therapeutic intervention, which was evaluated in the present study. Sixty-four adults presenting to Accident and Emergency departments following self-harm were allocated to a personal construct psychotherapy or a 'normal clinical practice' condition.

Recombinant human DNase (rhDNase) is an established treatment in cystic fibrosis (CF), but it may liberate cationic mediators bound to DNA in the airways. An alternative mucolytic therapy is hypertonic saline (HS); however, HS may potentiate neutrophilic inflammation. We compared the effect of rhDNase and HS on cationic proinflammatory mediators in CF sputum.
