A systematic review of the role of penicillin versus penicillin plus metronidazole in the management of peritonsillar abscess.

BACKGROUND: Peritonsillar abscess is a localised infection in the peritonsillar space. Pus from the abscess can contain anaerobes. Many clinicians prescribe metronidazole in addition to penicillin, but evidence to support this is limited. This review assessed the evidence of benefit of metronidazole for the treatment of peritonsillar abscess. METHODS: A systematic review was conducted of the literature and databases including Ovid Medline, Ovid Embase, PubMed and Cochrane library. Search terms included all variations of peritonsillar abscess, penicillin and metronidazole. RESULTS: Three randomised, control trials were included. All studies assessed the clinical outcomes after treatment for peritonsillar abscess, including recurrence rate, length of hospital stay and symptom improvement. There was no evidence to suggest additional benefit with metronidazole, with studies suggesting increased side effects. CONCLUSION: Evidence does not support the addition of metronidazole in first-line management of peritonsillar abscess. Further trials to establish optimum dose and duration schedules of oral phenoxymethylpenicillin would benefit clinical practice.

Late-onset swallowing outcomes post-treatment for head and neck cancer in a UK-based population.

BACKGROUND: Adverse swallowing outcomes following head and neck squamous cell carcinoma treatment in the context of late-onset post-radiotherapy changes can occur more than five years post-treatment. METHODS: A retrospective study was conducted utilising patient records from March 2013 to April 2015. Patients were categorised into 'swallow dysfunction' and 'normal swallow' groups. Quality of life was investigated using the MD Anderson Dysphagia Inventory and EuroQol questionnaires. RESULTS: Swallow dysfunction was seen in 77 (51 per cent) of 152 patients. Twenty-eight patients (36 per cent) in the swallow dysfunction group reported symptoms in year five. Swallow dysfunction was associated with stage IV head and neck squamous cell carcinoma (p < 0.001) and radiotherapy (p < 0.001). MD Anderson Dysphagia Inventory global scores showed significant differences between swallow dysfunction and normal swallow groups (p = 0.01), and radiotherapy and surgery groups (p = 0.03), but there were no significant differences between these groups in terms of MD Anderson Dysphagia Inventory composite or EuroQol five-dimensions instrument scores. CONCLUSION: One-third of head and neck squamous cell carcinoma survivors with swallow dysfunction still show symptoms at more than five years post-surgery, a point at which they are typically discharged.

Outpatient secondary care pathways for head and neck cancer referral result in patient delays for cancer treatment.

INTRODUCTION: The majority of head and neck cancer referrals are received through primary care. A proportion of cancer referrals are received through secondary care specialties. Local delivery plan (LDP) targets in Scotland for cancer investigation are set at 31 days for diagnosis and 62 days to start treatment. The aim was to audit referrals made through non-primary care pathways compared with the standard primary care pathways against LDP targets. METHODS: New head and neck cancer patients between 1 January 2014 and 1 January 2019 were included. Pathway points were recorded between referral to outpatient clinic, time to multidisciplinary team discussion (MDT) and finally MDT to treatment. RESULTS: 1,276 new patient referrals were received over a 5-year period. Of these, 136 (10%) were referred via non-primary care pathways. The mean time for urgent suspicion of cancer (USoC) referrals to start treatment was 77 days (15 days over target) and for outpatient secondary care referrals was 102 days (40 days over target) (p<0.05). When treatment intent was considered, 841/1,131 (75%) of patients referred via primary care were treated curatively compared with 49/99 (49%) (p<0.05) of patients referred through the secondary outpatient pathway. CONCLUSION: Patients with head and neck cancer referred from other outpatient specialties face delays commencing cancer treatment and are also associated with a greater likelihood of being treated with palliative intent.

Vocal cord movement: can it be accurately graded?

INTRODUCTION: Flexible nasendoscopy (FNE) is the principal assessment method for vocal cord movement. Because the procedure is inherently subjective it may not be possible for clinicians to grade the degree of vocal cord movement reliably. The aim of this study was to assess the accuracy and consistency of grading vocal cord movement as viewed via FNE. METHODS: Thirty FNE videos, without sound or clinical information, were assessed by six consultant head and neck surgeons. The surgeons were asked to assess and grade right and left vocal cord movement independently, based on a five-category scale. This process was repeated three times on separate occasions. Agreement and reliability were assessed. RESULTS: Mean overall observed inter-rater agreement was 67.7% (sd 1.9) with the five-category scale, increasing to 91.4% (sd 1.9) when a three-category scale was derived. Mean overall observed intra-rater agreement was 78.3% (sd 9.7) for five categories, increasing to 93.1% (sd 3.3) for three categories. Discriminating vocal cord motion was less reliable using the five-category scale (k = 0.52) than with the three-category scale (k = 0.68). CONCLUSIONS: This study demonstrates quantitatively that it is challenging to accurately and consistently grade subtle differences in vocal cord movement, as proven by the reduced agreement and reliability when using a five-point scale instead of a three-point scale. The study highlights the need for an objective measure to help in the assessment of vocal cord movement.

External validation of OroGrams as a predictive model for overall and progression-free survival in Scottish patients with oropharyngeal squamous cell carcinoma: a retrospective cohort study.

The aims of this study were to externally validate the OroGrams (oropharyngeal cancer survival calculator) nomogram in a Scottish cohort with high endemic smoking rates, and to compare survival rates with the original validation cohort. A retrospective cohort study in Greater Glasgow and Clyde ENT and OMFS departments was performed to investigate survival outcomes of patients with oropharyngeal squamous cell carcinoma (OPSCC) from January 2012 - December 2017. The main outcome measures were progression-free (PFS) and overall survival (OS), and Kaplan Meier curves. The predictive accuracy of OroGrams was investigated for survival probabilities at one, three, and five years. Smoking and HPV-negative cancer rates were significantly higher in Scottish patients than in the UK consortium cohort. A greater proportion of Scottish patients had advanced UICC8 stages. PFS in patients with HPV-negative cancer appeared better in the Scottish cohort than in the original cohort. Calculated mean standardised Brier scores for PFS and OS were below 0.2 at all three follow-up points, suggesting good overall prognostic accuracy, but there was wide variation between predictive accuracy in individual patients. OroGrams shows prognostic accuracy at one-year follow up in Scotland. The accuracy decreases with longer follow-up periods.

COVID-19: smoke testing of surgical mask and respirators.

BACKGROUND: Fluid Resistant Surgical Masks have been implemented in UK personal protective equipment (PPE) guidelines for COVID-19 for all care sites that do not include aerosol-generating procedures (AGPs). FFP3 masks are used in AGP areas. Concerns from the ENT and plastic surgery communities out with intensive care units have questioned this policy. Emerging evidence on cough clouds and health care worker deaths has suggested that a review is required. AIMS: To test the efficacy of Fluid Resistant Surgical Mask with and without adaptions for respiratory protection. To test the efficacy of FFP and FFP3 regarding fit testing and usage. METHODS: A smoke chamber test of 5 min to model an 8-h working shift of exposure while wearing UK guideline PPE using an inspiratory breathing mouthpiece under the mask. Photographic data were used for comparison. RESULTS: The Fluid Resistant Surgical Mask gave no protection to inhaled smoke particles. Modifications with tape and three mask layers gave slight benefit but were not considered practical. FFP3 gave complete protection to inhaled smoke but strap tension needs to be 'just right' to prevent facial trauma. Facial barrier creams are an infection risk. CONCLUSIONS: Surgical masks give no protection to respirable particles. Emerging evidence on cough clouds and health care worker deaths suggests the implementation of a precautionary policy of FFP3 for all locations exposed to symptomatic or diagnosed COVID-19 patients. PPE fit testing and usage policy need to improve to include daily buddy checks for FFP3 users.

'Urgent suspicion of cancer' referrals to a head and neck clinic - what do patients expect?

BACKGROUND: Public awareness of 'red flag' symptoms for head and neck cancer is low. There is a lack of evidence regarding patient concerns and expectations in consultations for cancer assessment. METHOD: This prospective questionnaire study examined the symptoms, concerns and expectations of 250 consecutive patients attending an 'urgent suspicion of cancer' clinic at a tertiary referral centre. RESULTS: The patients' most frequent responses regarding their concerns were 'no concerns' (n = 72, 29 per cent); 'all symptoms' were a cause for concern (n = 65, 26 per cent) and 'neck lump' was a symptom causing concern (n = 37, 17 per cent). The expectations of patients attending clinic were that they would find out what was wrong with them, followed by having no expectations at all. Overall patient knowledge of red flag symptoms was lacking and their expectations were low. CONCLUSION: Patients with non-cancer symptoms are frequently referred with suspected cancer. Patients with red flag symptoms are not aware of their significance and they have low expectations of healthcare.

One-year all-cause mortality for 338 patients admitted with epistaxis in a large tertiary ENT centre.

OBJECTIVE: Epistaxis is the most common ENT emergency. This study aimed to assess one-year mortality rates in patients admitted to a large teaching hospital. METHOD: This study was a retrospective case note analysis of all patients admitted to the Queen Elizabeth University Hospital in Glasgow with epistaxis over a 12-month period. RESULTS: The one-year overall mortality for a patient admitted with epistaxis was 9.8 per cent. The patients who died were older (mean age 77.2 vs 68.8 years; p = 0.002), had a higher Cumulative Illness Rating Scale-Geriatric score (9.9 vs 6.7; p < 0.001) and had a higher performance status score (2 or higher vs less than 2; p < 0.001). Other risk factors were a low admission haemoglobin level (less than 128 g/dl vs 128 g/dl or higher; p = 0.025), abnormal coagulation (p = 0.004), low albumin (less than 36 g/l vs more than 36 g/l; p < 0.001) and longer length of stay (p = 0.046). CONCLUSION: There are a number of risk factors associated with increased mortality after admission with epistaxis. This information could help with risk stratification of patients at admission and enable the appropriate patient support to be arranged.

Palliative intent treatment for head and neck cancer: an analysis of practice and outcomes.

BACKGROUND: There is little consensus on how best to manage head and neck cancer with palliative intent. Predicting outcome is difficult and reported survival varies. The present study sought to delineate local practice and outcomes in patients treated with palliative intent. METHODS: The clinical records of all head and neck cancer patients treated with palliative intent presenting between 2015 and 2016 to our multidisciplinary team were reviewed. RESULTS: Eighty-four patients (21.5 per cent) were treated with palliative intent. All had squamous cell carcinoma. Mean survival time was 151 days (standard deviation = 121.1; range, 8-536 days). Of the patients, 83.3 per cent had a palliative care referral; 74.1 per cent had a hospice referral. Patients received a variety of interventions, and there was an associated complication in 8.2 per cent. The mean number of days spent in hospital for interventions was 11.9 days (standard deviation = 12.5; range, 0-41 days). CONCLUSION: Different interventions are used to manage head and neck cancer patients with palliative intent, and these may be associated with significant morbidity. Survival time is variable, often several months; thus, any treatment must take into account morbidity in conjunction with the patient's wishes.

Outcomes of urgent suspicion of head and neck cancer referrals in Glasgow.

INTRODUCTION: Primary care patients with a suspected head and neck cancer are referred through the urgent suspicion of cancer referral pathway. Rates of cancer detection through this pathway are low. Evidence surrounding the pathway of these patients is lacking. This study aimed to determine the outcome of urgent suspicion of cancer referrals for head and neck cancer. METHODS AND METHODS: All head and neck cancer urgent suspicion of cancer referrals in NHS Greater Glasgow and Clyde between June 2015 and May 2016 were analysed in regard to their clinical pathway. RESULTS: There were 2116 urgent suspicion of cancer referrals in the one-year period. The overall cancer rate was 235 (11.8%), compared with 152 (7.6%) that resulted in a primary head and neck cancer diagnosis. Of the total, 851 (42.6%) were reassured and discharged after one clinic appointment; 536 (26.8%) were followed up for suspected benign pathology and 436 (21.8%) were actively investigated for cancer. CONCLUSION: A significant proportion of patients attending urgent suspicion of cancer clinic appointments can be seen and discharged in one clinic appointment, provided there is same day imaging available. Cancer identification rates through urgent suspicion of cancer pathways remain low.

The value of chest X-ray in the Scottish Referral Guidelines for suspected head and neck cancer in 2144 patients.

OBJECTIVE: In Scotland, patients with suspected head and neck cancer are referred on the basis of the Scottish Referral Guidelines for Suspected Cancer, rather than the National Institute for Health and Care Excellence guidelines. A chest X-ray should be requested by the general practitioner at the same time as referral for persistent hoarseness. The evidence for this is level 4. METHODS: This audit identified adherence to this recommendation and X-ray results. All 'urgent suspicion of cancer' referrals to the ENT department in the National Health Service Greater Glasgow and Clyde for 2015-2016 were audited. RESULTS: Persistent hoarseness for more than 3 weeks instigated referral in 318 patients (15.7 per cent). Chest X-ray was performed in 120 patients (38 per cent), which showed: no abnormality in 116 (96.7 per cent), features of infection in 2 (1.7 per cent) and something else in 2 patients (1.7 per cent). No chest X-ray altered the management of a patient. CONCLUSION: Performance of chest X-ray does not alter management and its removal from the Scottish Referral Guidelines for Suspected Cancer is recommended.

Deprivation in relation to urgent suspicion of head and neck cancer referrals in Glasgow.

AIM: To examine deprivation measured by the Scottish index of multiple deprivation (SIMD) and its relation to urgent suspicion of head and neck cancer referrals. A secondary aim was to examine the symptomatology generating urgent suspicion of cancer (USOC) referrals by SIMD category. METHODS: All "urgent suspicion of cancer" referrals to the GGC ENT department over a one-year period, between 2015 and 2016, were reviewed. Information was recorded anonymously and included demographics and red flag referral symptoms. RESULTS: A total of 1998 patients were assessed, 43.4% (n = 867) were male. A total of 171 (8.6%) patients had primary head and neck cancer. A total of 61 patients had other types of cancer, giving an all cause cancer rate of 11.6%. About 71.3% of primary patients with head and neck cancer (HNC) were male. The most common SIMD category observed was SIMD1, the most common SIMD category yielding a primary head and neck cancer diagnosis was SIMD1. Neck lump was the commonest symptom amongst all SIMD categories. CONCLUSION: A link between deprivation and USOC referrals has been established. A difference in gender distribution between referrals and HNC was observed, more females are referred but a significantly higher number of patients with HNC are males. Neck lump is a very strong referral indicator for HNC and intermittent hoarseness is not. The findings from this analysis could be used to refine local referral patterns and priority of referral.

The hidden cost of deep neck space infections

Introduction The incidence of deep neck space infection (DNSI) is rising and appears to be related to falling rates of tonsillectomy. The purpose of this study was to assess demographics of patients presenting with DNSI and the financial burden to the National Health Service (NHS). Methods Data were collected retrospectively on patients aged over 16 years admitted to NHS Greater Glasgow and Clyde with DNSI between 2012 and 2016. Demographics, aetiology and use of hospital resources were reviewed. The cost of hospital admissions was calculated using data from NHS Scotland's Information Services Division, the local diagnostics division and the British National Formulary. Results Seventy-four patients were admitted with DNSI during the study period. Forty (54%) were male. The mean age was 44.0 years (range: 16-86 years). The most frequent source of infection was the tonsil (n=30, 40.5%). The most common infective organism was Streptococcus constellatus (n=9, 12.2%). The mean length of stay was 11 days. Fifty-five patients (74.3%) required operative intervention. The mean cost of admission per patient was £5,700 (range: £332-£46,700). Conclusions This study highlights the high cost burden of DNSI to the NHS. The incidence of DNSI in Glasgow has risen over the study period; contributing factors may include the reduced tonsillectomy rate and a reduction in antibiotic prescribing. As the incidence of DNSI continues to rise, there will be an increase in cost to the NHS, which must be planned for.

Presenting symptoms and long-term survival in head and neck cancer.

OBJECTIVES: To assess how type and number of symptoms are related to survival in patients with head and neck cancer. DESIGN: Patients were followed up for over 10 years from the Scottish Audit of Head and Neck Cancer (national cohort of head and neck cancer patients in Scotland 1999-2001). September 2013, cohort was linked to national mortality data. First, second and third presenting symptoms were recorded at diagnosis. SETTING: National prospective audit-Scotland. PARTICIPANTS: A subset of 1589 patients, from the original cohort of 1895, who had cancer arising from one of the four main subsites; larynx, oropharynx, oral cavity and hypopharynx. MAIN OUTCOME MEASURES: Median survival in relation to patients' presenting symptoms. RESULTS: A total of 1146 (72%) males and 443 (28%) females, mean age at diagnosis 64 years (13-95). There was a significant difference in survival in relation to the number of the patient's presenting symptoms; one symptom had a median survival of 5.3 years compared with 1.1 years for three symptoms. Patients who presented with weight loss had a median survival of 0.8 years, compared to 4.2 years if they did not (P < .001). Patients who presented with hoarseness had a median survival of 5.9 years compared to 2.6 years without (P < .001). There was no significant difference in long-term survival for patients who presented with an ulcer, compared to those that did not (P = .105). CONCLUSIONS: This study highlights the importance of patients' presenting symptoms, giving valuable information in highlighting appropriate "red flag" symptoms and subsequent treatment planning and prognosis.

The effect of tonsillectomy on the morbidity from recurrent tonsillitis.

BACKGROUND: Tonsillitis is a common condition with an incidence in UK general practice of 37 per 1000 population a year.1 Recurrent tonsillitis results in significant morbidity and impacts on individuals' quality of life. This study assesses the morbidity and quality of life of adults with recurrent tonsillitis, and the impact of surgical intervention on their health state. OBJECTIVES: To describe disease-specific and global quality of life for adults with recurrent tonsillitis 6 months after tonsillectomy, using two instruments: the health impact of throat problems (HITP) and EuroQol-visual analogue scale questionnaire. To assess the overall health benefit from tonsillectomy as an intervention using the Glasgow Benefit Inventory (GBI). To assess potential predictors of tonsillectomy benefit. DESIGN: A prospective, observational cohort audit of patients who have fulfilled Scottish Intercollegiate Guideline Network (SIGN) criteria for tonsillectomy.2 SETTING: Secondary care, teaching hospital. PARTICIPANTS: Seventy patients (57 female), median age 20 years (range 13-41). RESULTS: Median preoperative HITP was 47 (range 15-67), compared to 4 (0-72), (P<.001) 6 months following surgery. Median HITP difference was 39.5 (range -20 to 75). There was no significant change in global Quality of Life. Median overall 6 months GBI was 39 (-3 to 100). Patients had an average of 27 episodes of tonsillitis over a period of seven years before "achieving" tonsillectomy, significantly higher than the SIGN guidelines of three or more episodes over three years. CONCLUSIONS: Recurrent tonsillitis causes a poor disease-specific quality of life. Patients experienced a median of three episodes per year for seven years before tonsillectomy. Following tonsillectomy, patients had a significant improvement in their disease-specific quality of life. Baseline HITP significantly improved after tonsillectomy. The results imply patients with recurrent acute tonsillitis may be experiencing undue delay.

Paediatric tracheostomy-An 11 year experience at a Scottish paediatric tertiary referral centre.

AIMS: The aim of this paper was to review the indications, complications and outcomes for tracheostomy at a Scottish paediatric tertiary referral hospital. METHODS: All patients undergoing tracheostomy between January 2001 and September 2012 were identified. A retrospective case note analysis was performed. RESULTS: 111 tracheostomies were done in the study period. The mean number per year was 11 (3-12). Full data was available for 95 patients. There were 56 (59%) males and 39 (41%) females. Age at time of tracheostomy ranged from one day to 15 years, the mean age of tracheostomy insertion was 69 weeks. The majority of patients, 75 (79%), were under one year old when they had their tracheostomy. The most common indication was long-term ventilation (20%), followed by craniofacial abnormality causing airway obstruction (18%), followed by subglottic stenosis (14%). 37% of patients were decannulated. CONCLUSIONS: This series reflects current trends in the indications for paediatric tracheostomy, with chronic lung disease of prematurity being the most common indication.

Risk factors for failure of supraglottoplasty.

OBJECTIVES: To assess for identifiable risk factors for failed surgical intervention in children with laryngomalacia. METHODS: Retrospective case note review between September 2007 and March 2012. Case notes were reviewed for demographic data, symptoms, co-morbidities, operative technique, postoperative recovery, complications, length of hospital stay including intensive care unit (ICU) care, and resolution of symptoms. RESULTS: 148 children underwent supraglottoplasty. Case notes were available for 115 (78%) patients. 35% (41/115) of cases were females and 65% (74/115) were male. A bimodal age distribution was observed with peaks at 3 months and 3.5 years. Those over one year of age were more likely to have complications (p = 0.035). There was no significant difference in outcomes for age (p > 0.05). In patients less than one year, reflux symptoms were significantly associated with a higher likelihood of failure of the operation (p = 0.013). Patients under one year with pre-operatively identified comorbid conditions were less likely to have an improvement in breathing (p = 0.002). Cold steel was used in 55% (63/115) of cases, laser only in 17% (20/115) cases and a combination of the two techniques in 28%, (32/115). There was no association between the surgical technique used and complications (p = 0.558). There was no association between improvement in symptoms and surgical technique used (p = 0.560). There was a significant association between delayed post-operative neurological diagnosis and failure of the operation (p < 0.001). 21 (18%) patients required a second procedure. CONCLUSIONS: Pre-operative predictors of failure were patients with reflux symptoms (p = 0.013). Patients that required a second procedure were 37 times more likely to have a delayed diagnosis of an underlying neurological condition. Failure of symptoms to improve after supraglottoplasty should alert the clinician to the possibility of an underlying neurological disorder.

Paediatric thyroid cancer: the Scottish experience.

BACKGROUND AND AIMS: Paediatric thyroid cancer is a rare disease, making diagnosis and treatment particularly challenging. Here we present the Scottish experience of thyroid cancer in the paediatric population and give an overview of how a child or adolescent that presents with a thyroid nodule should be investigated and managed. METHODS AND RESULTS: Data has been obtained from ISD Scotland, giving population-based information on paediatric thyroid cancer. A literature review has been performed on the management and treatment of thyroid cancer in the younger population. Paediatric thyroid cancer in Scotland is a rare disease, although the incidence is increasing each year. In general, differentiated paediatric thyroid cancer carries a good prognosis, while the results are more mixed in the rarer pathologies such as medullary cancer. CONCLUSION: Due to the small numbers of patients diagnosed each year in Scotland, it is imperative that these patients are discussed at a multidisciplinary thyroid MDT and managed in a tertiary referral centre by consultants and medical/nursing support staff who have experience in treating these patients.

Lack of prognostic effect of carbonic anhydrase-9, hypoxia inducible factor-1α and bcl-2 in 286 patients with early squamous cell carcinoma of the glottic larynx treated with radiotherapy.

AIMS: To evaluate the prognostic significance of potential tumour markers of hypoxia and apoptosis in early squamous cell carcinoma of the glottic larynx managed with radiotherapy. MATERIALS AND METHODS: In total, 382 patients with T1 and T2 squamous cell carcinoma of the glottic larynx (vocal cords) received radical radiotherapy (50-55 Gy, in 16 fractions in 98% of cases). Pre-treatment haemoglobin was available for 328 patients; biopsy samples were available for 286. Immunohistochemistry was carried out for carbonic anhydrase-9 (CA-9), hypoxia inducible factor-1α (HIF-1α) and Bcl-2. RESULTS: At 5 years, locoregional control was achieved in 88.2%, cancer-specific survival in 95.0% and overall survival in 78.7%. Adverse prognostic factors for locoregional tumour recurrence were pre-treatment haemoglobin <13.0 g/dl (P = 0.035, Log rank test; sensitivity 0.28, specificity 0.84) and stage T2 rather than T1 (P = 0.002). The effect of haemoglobin level on locoregional control was not significant when stratified by the median of 14.2 g/dl (P = 0.43) or as a continuous variable (P = 0.59). High CA-9 (P = 0.11), HIF-1α (P = 0.67) and Bcl-2 (P = 0.77) expression had no prognostic significance. CONCLUSIONS: High CA-9, HIF-1α and Bcl-2 do not add to the prognostic significance of tumour stage and lower haemoglobin in predicting failure of local control in early glottic larynx squamous cell carcinoma managed with radiotherapy. The effect of haemoglobin was not strong enough to be useful as a prognostic biomarker.
