Prevalence of asthma, aspirin sensitivity and allergy in chronic rhinosinusitis: data from the UK National Chronic Rhinosinusitis Epidemiology Study.

BACKGROUND: Chronic rhinosinusitis (CRS) is a common disorder associated with other respiratory tract diseases such as asthma and inhalant allergy. However, the prevalence of these co-morbidities varies considerably in the existing medical literature and by phenotype of CRS studied. The study objective was to identify the prevalence of asthma, inhalant allergy and aspirin sensitivity in CRS patients referred to secondary care and establish any differences between CRS phenotypes. METHODS: All participants were diagnosed in secondary care according to international guidelines and invited to complete a questionnaire including details of co-morbidities and allergies. Data were analysed for differences between controls and CRS participants and between phenotypes using chi-squared tests. RESULTS: The final analysis included 1470 study participants: 221 controls, 553 CRS without nasal polyps (CRSsNPs), 651 CRS with nasal polyps (CRSwNPs) and 45 allergic fungal rhinosinusitis (AFRS). The prevalence of asthma was 9.95, 21.16, 46.9 and 73.3% respectively. The prevalence of self-reported confirmed inhalant allergy was 13.1, 20.3, 31.0 and 33.3% respectively; house dust mite allergy was significantly higher in CRSwNPs (16%) compared to CRSsNPs (9%, p < 0.001). The prevalence of self- reported aspirin sensitivity was 2.26, 3.25, 9.61 and 40% respectively. The odds ratio for aspirin sensitivity amongst those with AFRS was 28.8 (CIs 9.9, 83.8) p < 0.001. CONCLUSIONS: The prevalence of asthma and allergy in CRS varies by phenoytype, with CRSwNPs and AFRS having a stronger association with both. Aspirin sensitivity has a highly significant association with AFRS. All of these comorbidities are significantly more prevalent than in non-CRS controls and strengthen the need for a more individualised approach to the combined airway.

Atypical presentation of Bezold's and Citelli's abscesses, with recollection following an incomplete postoperative course of antibiotics.

Bezold's and Citelli's abscesses are rare complications of otitis media. We present a case of a 44-year-old Eastern European man, with a history of recurrent otitis media, who was admitted to hospital with mastoiditis and initially treated with antibiotics. Despite clinical improvement, a CT scan showed mastoiditis with Bezold's and Citelli's abscesses. The patient underwent a myringotomy and grommet insertion, in addition to a cortical mastoidectomy and curettage of the neck abscesses. After a good recovery, he was discharged home. However, likely due to the language barrier, he did not complete a course of antibiotics as prescribed, and the abscess re-collected, necessitating a re-admission and re-operation. This report illustrates the importance of considering rare features of a common disease in the differential, and of communication in ensuring compliance.

A case-control study of medical, psychological and socio-economic factors influencing the severity of chronic rhinosinusitis.

BACKGROUND: Chronic rhinosinusitis (CRS) is a common and debilitating disorder. Little is known about the epidemiology of this disease. The aims of the study were to identify differences in socio-economic variables and quality of life between patients with chronic rhinosinusitis and healthy controls, to identify any significant associations between CRS and other medical co-morbidities, psychiatric disease or environmental exposure and to explore the experience of CRS from the perspective of CRS sufferers. METHODS: Participants were recruited from ENT clinics from 30 centres across the UK. They completed a study-specific questionnaire considering environmental, medical and socio-economic factors, and SF-36 and SNOT-22 scores. All participants with CRS were diagnosed by a clinician and categorised as having CRS (with polyposis, without polyposis or allergic fungal rhinosinusitis (AFRS)). Controls included family and friends of those attending ENT outpatient clinics and hospital staff who had no diagnosis of nose or sinus problems and had not been admitted to hospital in the previous 12 months. RESULTS: A total of 1470 study participants (1249 patients and 221 controls) were included in the final analysis. Highly significant differences were seen in generic and disease-specific quality of life scores between CRS sufferers and controls; mean SNOT-22 score 45.0 for CRS compared with 12.1 amongst controls. There were no clear differences in socioeconomic variables including social class, index of multiple deprivation and educational attainment between cases and controls. Common comorbidities with a clear association included respiratory and psychiatric disorders, with a higher frequency of reported upper respiratory tract infections. CONCLUSIONS: CRS is associated with significant impairment in quality of life and with certain medical co-morbidities. In contrast to other common ENT disorders, no socioeconomic differences were found between patients and controls in this study.

The burden of revision sinonasal surgery in the UK-data from the Chronic Rhinosinusitis Epidemiology Study (CRES): a cross-sectional study.

OBJECTIVES: The aim of this study was to investigate the surgical revision rate in patients with chronic rhinosinusitis (CRS) in the UK CRS Epidemiology Study (CRES). Previous evidence from National Sinonasal Audit showed that 1459 patients with CRS demonstrated a surgical revision rate 19.1% at 5 years, with highest rates seen in those with polyps (20.6%). SETTING: Thirty secondary care centres around the UK. PARTICIPANTS: A total of 221 controls and 1249 patients with CRS were recruited to the study including those with polyps (CRSwNPs), without polyps (CRSsNPs) and with allergic fungal rhinosinusitis (AFRS). INTERVENTIONS: Self-administered questionnaire. PRIMARY OUTCOME MEASURE: The need for previous sinonasal surgery. RESULTS: A total of 651 patients with CRSwNPs, 553 with CRSsNPs and 45 with AFRS were included. A total of 396 (57%) patients with CRSwNPs/AFRS reported having undergone previous endoscopic nasal polypectomy (ENP), of which 182 of the 396 (46%) reported having received more than one operation. The mean number of previous surgeries per patient in the revision group was 3.3 (range 2-30) and a mean duration of time of 10 years since the last procedure. The average length of time since their first operation up to inclusion in the study was 15.5 years (range 0-74). Only 27.9% of all patients reporting a prior ENP had received concurrent endoscopic sinus surgery (ESS; n=102). For comparison, surgical rates in patients with CRSsNPs were significantly lower; 13% of cases specifically reported ESS, and of those only 30% reported multiple procedures (χ(2) p<0.001). CONCLUSIONS: This study demonstrated that there is a high burden of both primary and revision surgery in patients with CRS, worst in those with AFRS and least in those with CRSsNPs. The burden of revision surgery appears unchanged in the decade since the Sinonasal Audit.

Lipoma of the pinnal helix: a very unusual location for a very common tumour.

Lipomas are common benign tumours but can present in unusual locations. The authors present the rare case of a pedunculated lipoma of the pinnal helix. The lipoma was excised with good cosmetic result. Lipoma of the cartilaginous pinnal helix is rare and has not been described previously in the literature.

Using a microscope to change a speech valve.

Replacing a speech valve can be a difficult procedure to learn and perform. In this letter the authors propose a method using an operating microscope, which their department has found useful in performing this procedure, and in teaching trainees.

Serological investigation of IgG levels and subclasses in rheumatoid arthritis patients following ingestion of bovine type II collagen: results of a double blind, randomised controlled trial.

The purpose of this study was to investigate whether clinical improvement in patient with rheumatoid arthritis (RA) taking oral Bovine type II collagen (bCII) is associated with changes in levels of anti-bCII total IgG antibody and its subclasses. Four groups were given either 5, 0.5 or 0.05 mg of bCII or a placebo in a double-blind randomised control trial. The sera IgG anti-collagen type II and antibodies of the IgG subclasses, IgG1-4, were measured at the start and end of the trial by ELISA. Total IgG anti-collagen II antibodies in the pooled active treatment groups were statistically significantly reduced compared with the placebo group (p = 0.021). Decreasing total IgG titres were observed in the 0.5-mg group (p = 0.008), 0.05-mg group (p = 0.004) and 5-mg group (p = 0.078) before and after treatment. For IgG1, IgG2, IgG3 and IgG4 subclasses, in the 0.5-mg group in which the best clinical response was observed, there was statistically significant decreases observed in the IgG2 and IgG3 subclasses (p = 0.047, p = 0.046). Treatment with bCII in patients with RA led to a reduction in anti-collagen II antibody titre indicating an active biological effect as observed previously in animal model of RA. The largest decrease in total and subclasses of anti-collagen antibody titres occurred in the groups of patients with the best therapeutic response to bCII, supporting the conclusion of the clinical trial and suggests that immune regulation explains the therapeutic effect.
