RESUMEN
INTRODUCTION: Pharmacological salicylates are known to trigger respiratory exacerbations in patients with Non-Steroidal Exacerbated Respiratory Disease (N-ERD), a specific phenotype of Chronic Rhinosinusitis (CRS) and asthma. The impact of dietary sources of salicylates across subgroups of CRS is not well understood. The hypothesis is that in patients with nasal polyps present, there is likely to be a higher incidence of symptom exacerbation due to dietary salicylates regardless of any known response to pharmacological salicylate. METHODS: The Chronic Rhinosinusitis Epidemiology Study (CRES) was a questionnaire-based case-control study which sought to characterise the UK CRS population in terms of sociological, economic and medical factors. Using specific questions to examine participant responses relating to symptom exacerbation from food groups thought to be high in salicylate content, this analysis of the CRES database sought to compare an estimate of the prevalence of dietary sensitivity due to food with higher potential salicylate content across patients with CRS with (CRSwNPs) and without nasal polyposis (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). RESULTS: The CRSwNPs group were significantly more likely than controls to report symptom exacerbation due to ingestion of food groups with higher potential dietary salicylate content. The same trend was observed amongst CRSsNPs participants to a lesser degree. Reported response to the individual specific food groups wine, nuts, spicy foods, fruit and vegetables demonstrated that a statistically significant proportion of CRSwNPs and AFRS participants reported sensitivity to wine. CONCLUSIONS: This analysis suggests that there is an association between symptom exacerbation in response to food products with higher potential salicylate content, specifically wine, in CRS patients both with and without nasal polyposis when compared to controls, but especially in the CRSwNPs and AFRS phenotypes. Further studies are needed to detail if this relationship represents a causal relationship to dietary salicylate. The data present the possibility that a wider group of CRS patients may elicit salicylate sensitivity than those with known N-ERD.

OBJECTIVES: According to clinical and comissioning guidelines for chronic rhinosinusitis (CRS), patients being referred to secondary care should have failed primary medical treatment with nasal douching (ND) and intranasal corticosteroids (INCS). The study objectives were to identify the rate of specific medical therapy in CRS patients and establish any differences in medication use, for both CRS and associated medical conditions, between CRS phenotypes. DESIGN AND SETTING: Case-control study in a secondary care setting. METHODS: Participant-reported study-specific questionnaire capturing free text data on current medication use at the time of study entry. Qualitative interviews with 21 participants also explored their experience of CRS and its management. PARTICPANTS: Patients both without (CRSsNPs) and with polyps (CRSwNPs). MAIN OUTCOME MEASURES: Reported use of CRS-related and non-related medications. RESULTS: Within a total of 1243 CRS participants, current INCS usage was low (18% in CRSwNPs, 12% in CRSsNPs); ND was being performed by only 1% of all participants. Bronchodilators and inhaled corticosteroids use was significantly higher in CRSwNPs participants (P < .0001). Antidepressant use was significantly higher in CRSsNPs (14% vs 7%, P < .0002). There were no significant regional variations in rates of INCS use, nor any significant influence of social deprivation. CONCLUSIONS: The current use of baseline medical therapy in CRS appears to be very low, representing a combination of poor patient compliance, possible ineffectiveness of treatment and a lack of familiarity with current guidelines amongst general practitioners and some ENT specialists. Work is needed to disseminate guidelines to all practitioners involved and reduce unnecessary burden on existing healthcare resources for this common condition by ensuring timely referral and definitive management.

OBJECTIVE: This study aimed to measure changes in disease-specific quality of life in children following tonsillectomy or adenotonsillectomy. METHODS: A multicentre prospective cohort study was performed involving seven ENT departments in England. A total of 276 children entered the study over a 2-month period: 107 underwent tonsillectomy and 128 adenotonsillectomy. Forty-one children referred with throat problems initially managed by watchful waiting were also recruited. The follow-up period was 12 months. Outcome measures were the T14, parental impressions of their child's quality of life and the number of days absent from school. RESULTS: One-year follow-up data were obtained from 150 patients (52 per cent). The mean baseline T14 score in the non-surgical group was significantly lower (T14 = 23) than in the tonsillectomy group (T14 = 31) or the adenotonsillectomy group (T14 = 35; p < 0.001). There was a significant improvement in the T14 scores of responders in all groups at follow up. The effect size was 1.3 standard deviations (SD) for the non-surgical group, 2.1 SD for the tonsillectomy group and 1.9 SD for the adenotonsillectomy group. Between-group differences did not reach statistical significance. A third of children in the non-surgical group underwent surgery during the follow-up period. CONCLUSION: Children who underwent surgical intervention achieved a significant improvement in disease-specific quality of life. Less severely affected children were managed conservatively and also improved over 12 months, but 1 in 3 crossed over to surgical intervention.

Necrotising otitis externa is an uncommon and aggressive infection of the external auditory canal with a tendency to present in the elderly and immunocompromised patient. We report a series of twenty-five patients admitted to our institution over a four-year period with this diagnosis. We review the diagnosis and antimicrobial management of these cases, and propose a treatment algorithm based on our experience.

BACKGROUND: Although relatively uncommon, penetrating neck trauma has the potential for serious morbidity and an estimated mortality of up to 6%. The assessment and management of patients who have sustained a penetrating neck injury has historically been an issue surrounded by significant controversy. OBJECTIVES OF REVIEW: To assess recent evidence relating to the assessment and management of penetrating neck trauma, highlighting areas of controversy with an overall aim of formulating clinical guidelines according to a care pathway format. TYPE OF REVIEW: Structured, non-systematic review of recent medical literature. SEARCH STRATEGY: An electronic literature search was performed in May 2011. The Medline database was searched using the Medical Subject Headings terms 'neck injuries' and 'wounds, penetrating' in conjunction with the terms 'assessment' or 'management'. Embase was searched with the terms 'penetrating trauma' and 'neck injury', also in conjunction with the terms 'assessment' and 'management'. Results were limited to articles published in English from 1990 to the present day. EVALUATION METHOD: Abstracts were reviewed by the first three authors to select full-text articles for further critical appraisal. The references and citation links of these articles were hand-searched to identify further articles of relevance. RESULTS: 147 relevant articles were identified by the electronic literature search, comprising case series, case reports and reviews. 33 were initially selected for further evaluation. CONCLUSIONS: Although controversy continues to surround the management of penetrating neck trauma, the role of selective non-operative management and the utility of CT angiography to investigate potential vascular injuries appears to be increasingly accepted.

OBJECTIVES: Woodworkers' adenocarcinoma of the ethmoid sinuses is an extremely rare occupational malignancy with a locally aggressive course. Treatment with surgical exenteration and topical 5 fluorouracil (5FU) packs has become standard treatment over the last 10 years in this ENT unit. This study presents level 2 evidence that 5FU provides improved survival over previous management with primary radiotherapy and salvage craniofacial resection. DESIGN: Retrospective case series with historical control group. SETTING: District General Hospital. PARTICIPANTS: The records of 31 consecutive patients with the disease were analysed. Five patients died prior to treatment. One patient was treated with surgery alone and therefore excluded. Twenty-five patients were included in the analysis. Fourteen were treated with primary radiotherapy and 11 with surgery and topical 5FU. OUTCOME MEASURES: Disease free survival was measured using Kaplan-Meier survival analysis. RESULTS: Five-year disease free survival improved from 50% with primary radiotherapy to 86% with surgery and 5FU. This improvement is statistically significant (P = 0.03). CONCLUSION: Topical 5FU treatment improves survival of Woodworker's adenocarcinoma of the ethmoid sinuses. This finding may be useful in the treatment of other locally aggressive sinonasal malignancies.

Evidence-based medicine (EBM) is defined as "the process of systematically finding, appraising and using contemporaneous research findings as the basis for clinical decisions". Although EBM has been extensively described across the Americas and Europe, no study has looked at the practice of EBM in Puerto Rico. A cross-sectional analysis based on a 23-item questionnaire was employed. We showed that there is a high use (88%) and familiarity (93%) with EBM, and that physicians keep a positive attitude towards EBM (80%) in Puerto Rico. There is an over-representation of academicians (58.9% vs. 34.6%, p = 0.02) and an under-representation of solo office practitioners (10.5% vs. 26.9%, p = 0.03) among EBM users. Additionally, patient workload (48%), time constraints (36%), and limited access to the Internet (28%) were the most frequently cited obstacles to the practice of EBM in Puerto Rico. Taken together, these results help create a cross-sectional profile of EBM practice among Puerto Rican physicians.

OBJECTIVES: To determine the best Foley catheter and inflation fluid for post-nasal packing. DESIGN: Experimental study. SETTING: District General Hospital (Wexham Park Hospital). MATERIALS: 108 latex and 108 silicone catheters were directly compared. OUTCOME MEASURES: Catheters were analysed according to the inflation fluid instilled and the use of an umbilical clamp. Analysis occurred at 24, 36, 48 and 72 h periods after being placed in humidified incubator at 37 degrees C. The main outcome measure was whether deflation was possible at specified times. The secondary outcome measure was an attempt to identify the failure point in those catheters that failed to deflate. RESULTS: Air was found to be an unsuitable inflation fluid for either silicone or latex catheters due to a 100% spontaneous deflation rate within a 24-h period. Silicone catheters were found to be 100% reliable when inflated with water or saline, irrespective of the use of a clamp. Latex catheters were unreliable with an overall failure rate of 30%. This high failure rate was related both to the use of an umbilical clamp to secure the catheter and to the use of saline as the inflation medium. CONCLUSIONS AND RECOMMENDATIONS: Firstly, air should not be used for inflation of catheters unless specified in manufacturer's instructions. Secondly, when Foley catheters are used for post-nasal packing, silicone should be considered the first choice of catheter type. If not available, latex ones may be used but should be inflated with water and secured with a non-crushing clamp at the alar rim.
