Isolated primary squamous cell carcinoma of the tympanic membrane

INTRODUCTIONPrimary squamous cell carcinoma (SCC) of the tympanic membrane is exceptionally rare. We describe the history, investigation and management of this disease.PRESENTATION OF CASEA 68-year-old woman presented with a three month history of intermittent otorrhoea and external ear canal (EAC) pruritus. Otoscopy revealed a polypoidal granular nodule, confined to the posterior aspect of the tympanic membrane. Examination under anaesthesia (EUA) confirmed that the lesion was confined to the tympanic membrane, with a surrounding rim of normal drum. Biopsies were consistent with well differentiated SCC.DISCUSSIONFollowing discussion at multi-disciplinary team meeting for treatment planning, the patient underwent lateral temporal bone resection with ipsilateral superficial parotidectomy and selective neck dissection. Post-operative histology confirmed an SCC confined to the tympanic membrane.CONCLUSIONSCC of the tympanic membrane is an extremely rare condition. As with early temporal bone SCC, surgical resection with adjacent structure clearance remains the primary treatment modality.     

A retrospective analysis comparing set up errors from standard versus customised headrests for head and neck radiotherapy

IntroductionIn response to advice from The National Institute for Health and Care Excellence ⁽¹⁾ to reduce hospital visits during COVID-19, standard headrests were introduced for head and neck radiotherapy within Northern Centre for Cancer Care (NCCC). The standard headrest requires one mould room appointment compared to 3 appointments with customised headrests.MethodsTwo groups of 10 patients treated between December 2019 and June 2020 were retrospectively analysed by 1 observer. Groups were stratified according to age, sex and tumour site. One group had customised headrest and the other had standard headrest. Five hundred and forty seven cone beam computed tomography images were reviewed. A 6 Degree of Freedom match was performed then chin, shoulder and spine position were assessed using dosimetrist drawn structures. Structures out of the tolerance were recorded. A chi-squared test was used for statistical analysis.ResultsThe out of tolerance chin position count recorded was 21 for customised headrest and 36 for standard headrest, p-value 0.046. The shoulder position count was 13 for customised headrest and 77 for standard headrest p-value <0.001. The spine position count was 3 for CHR and 21 for standard headrest, p-value <0.001. This means the headrests compared are not equivalent in terms of set up reproducibility. Overall the standard headrest group had 10 set-up re-scans and no set up re-scans were recorded in the customised headrest group.ConclusionFewer hospital visits with SHR reduce patient exposure to COVID-19. However, CHR provided a more reliable level of immobilisation in this study.Implications for practiceThe radiotherapy service will be reviewed in line with these findings.     

Health economic evidence gaps and methodological constraints in low back pain and neck pain: Results of the Research Agenda for Health Economic Evaluation (RAHEE) project

Despite the increased interest in economic evaluations, there are difficulties in applying the results of such studies in practice. Therefore, the “Research Agenda for Health Economic Evaluation” (RAHEE) project was initiated, which aimed to improve the use of health economic evidence in practice for the 10 highest burden conditions in the European Union (including low back pain [LBP] and neck pain [NP]). This was done by undertaking literature mapping and convening an Expert Panel meeting, during which the literature mapping results were discussed and evidence gaps and methodological constraints were identified. The current paper is a part of the RAHEE project and aimed to identify economic evidence gaps and methodological constraints in the LBP and NP literature, in particular.The literature mapping revealed that economic evidence was unavailable for various commonly used LBP and NP treatments (e.g., injections, traction, and discography). Even if economic evidence was available, many treatments were only evaluated in a single study or studies for the same intervention were highly heterogeneous in terms of their patient population, control condition, follow-up duration, setting, and/or economic perspective. Up until now, this has prevented economic evaluation results from being statistically pooled in the LBP and NP literature, and strong conclusions about the cost-effectiveness of LBP and NP treatments can therefore not be made. The Expert Panel identified the need for further high-quality economic evaluations, especially on surgery versus conservative care and competing treatment options for chronic LBP. Handling of uncertainty and reporting quality were considered the most important methodological challenges.     

Neck of femur fractures in the elderly: Does every hour to surgery count?

ObjectivesTo determine if early surgery before 12 h confers a survival or length of stay benefit for patients with neck of femur (NOF) fractures.DesignRetrospective review of prospectively collected data.SettingDistrict general hospital.Patients1913 patients aged over 60 admitted with a fractured NOF who underwent surgery between 2011 and 2015. Mean age was 83.9 years. 73.7% were female.InterventionPatients had surgery for fractured NOF with data collected on demographics, mortality and length of stay.Main outcome measurementsData collected included gender, age, ASA grade, fracture anatomy, surgery, time to surgery, days spent in acute hospital and rehabilitation settings and 30-day mortality. Statistical analysis was used to identify independent predictors of mortality and length of stay.Results30-day mortality was 6.1% and the mean hospitalisation time was 13 ± 11.3 days for the acute hospital and 20.2 ± 17.2 days for the trust. Operations were performed at a mean of 23.8 ± 14.8 h after presentation. Age, gender, ASA grade and type of fracture were independent predictors of either mortality or length of stay. Timing of surgery had an association with mortality but this only reached statistical significance at 24 h.In line with previous studies we analysed time to surgery in 12 h blocks. We also used logistic regression, recognizing time as a continuous variable, which revealed that every hour of delay to surgery increased the mortality risk by 1.8%.ConclusionsWhile every hour of delay increased mortality risk, the association with mortality only became statistically significant when delaying over 24 h. This supports a pragmatic approach, with surgery as soon as medically possible without a race to theatre.Level of evidenceLevel III retrospective cohort study.

Reliability of two pragmatic tools for assessing text neck

Background

There is a hypothesis that the growing use of mobile phones in an inappropriate posture to text and read (text neck) could be a reason for the increasing prevalence of neck pain in the past decade. Before testing if there is an association between text neck and neck pain, it is necessary to develop reliable pragmatic tools appropriate to epidemiological studies.
