Utilization patterns of systemic corticosteroid use for chronic rhinosinusitis

Objective: We sought to characterize the utilization pattern and factors associated with use of systemic corticosteroids for CRS.

Methods: This was a cross-sectional study of 236 participants with CRS who were prospectively recruited. Participants reported the number of CRS-related oral corticosteroid courses taken in the last year. Baseline CRS symptomatology was measured using the 22-item Sinonasal Outcome Test (SNOT-22) and SNOT-22 sleep, nasal, otologic/facial pain and emotional subdomain scores. Clinical and demographic characteristics were also collected. Association was determined between patient characteristics and oral corticosteroid use in the last year for CRS.

Results: Sleep (p?=?.026), nasal (p?p?=?.022) SNOT-22 subdomain scores, and nasal polyps (p?=?.007) were associated with CRS-related oral corticosteroid use. In study participants without polyps, past CRS-related oral corticosteroid use was associated with sleep (adjusted OR?=?1.56, 95%CI: 1.01–2.40, p?=?.043), otologic/facial pain (adjusted OR?=?1.65, 95%CI: 1.09–2.51, p?=?.019) and nasal subdomain scores (adjusted OR?=?1.59, 95%CI: 1.01–2.51, p?=?.047). In study participants with polyps, past CRS-related oral corticosteroid use was only associated with the nasal subdomain score (adjusted OR?=?2.20, 95%CI: 1.40–3.45, p?=?.001).

Conclusions: Past CRS-related oral corticosteroid use was associated with increased baseline severity of specific symptoms, which were different depending on the presence of polyps.     

Prevalence of sinonasal outcome test (SNOT‐22) symptoms in patients undergoing surgery for chronic rhinosinusitis in the England and Wales National prospective audit

Clin. Otolaryngol. 2012, 37 , 276–282 Objectives: Review and evaluate the prevalence and severity of individual symptoms in patients with chronic rhinosinusitis (CRS) with or without nasal polyposis. Design and Setting: Retrospective analysis of data from the National Comparative Audit of Surgery for Nasal Polyposis and CRS, carried out across 87 hospitals in England and Wales between 2000 and 2001. Participants: A total of 2573 patients with CRS (1784 had CRS with nasal polyposis, 789 without nasal polyposis) who had undergone sinus surgery. Main outcome measures: Severity of clinical symptoms scores was graded on the Sino‐Nasal Outcome Test 22 questionnaire. Prevalence of these symptoms and mean symptom scores were calculated for each group of patients at baseline and 3 months after surgery. Results: In both groups, nasal blockage/congestion had the highest mean symptom score, followed by altered smell/taste and then the need to blow nose. These three symptoms were the most prevalent in the group with nasal polyposis. In the group without nasal polyposis, nasal blockage was also the most prevalent individual symptom (93.5%) followed by altered smell/taste (75.7%). The third most prevalent symptom was waking up tired (69.9%). The average test score preoperatively was 41.5 (group with nasal polyposis) and 44.4 (group without nasal polyposis). This decreased to 18.3 and 14.1, respectively, 3 months after surgery (P < 0.001). Conclusion: The leading three symptoms were nasal blockage/congestion, altered taste/smell and the need to blow the nose in terms of severity and prevalence. The total Sino‐Nasal Outcome Test 22 and all individual symptom scores improved significantly after surgery.     

Nasal polyps in the olfactory cleft

Objectives: Nasal polyps frequently arise from the middle meatus in patients with nasal polyposis, but caution is required when polyps are seen protruding from the olfactory cleft. The purpose of this study was to evaluate a method to achieve effective and safe access to the olfactory cleft, and to determine the actual incidence of polyps arising from the olfactory cleft in patients with nasal polyposis. Patients: Eighty-four patients with bilateral or unilateral nasal polyps (n = 143) ranging in age from 16 to 72 years underwent endoscopic sinus surgery in the period from January 1994 to December 1996. Methods: To observe and gain access to the olfactory cleft, septoplasty combined with endoscopic sinus surgery was needed in patients with nasal polyposis. Results: The endoscopy during the combined septoplasty and endoscopic sinus surgery revealed that 36.4% (n = 52) of bilateral or unilateral nasal polyps (n = 143) arose from the olfactory cleft. Of 52 polyps of olfactory cleft origin, 45 (86.5%) arose from the superior turbinate and/or superior meatus, 32 (67.3%) from the medial side of the middle turbinate, 24 (46.2%) from the anterior face of the sphenoid sinus, and 17 (32.7%) from the mucosa of the nasal septum. Conclusions: These findings suggest that for surgeries of nasal polyposis an approach to the olfactory cleft as well as to the middle meatus is required.     

慢性鼻-鼻窦炎患者嗅觉障碍影响因素分析

目的：探讨慢性鼻-鼻窦炎（CRS）患者嗅觉障碍的影响因素。方法：采用视觉模拟量表（VAS）对270例诊断明确的CRS患者的嗅觉障碍程度进行评分,分为嗅觉障碍影响生活质量组（VAS〉5）及未影响生活质量组（VAS≤5）。通过对患者年龄、性别、伴鼻息肉、伴变应性鼻炎、有吸烟史及前期鼻部手术史等临床因素及血清总IgE水平、外周血嗜酸粒细胞和单个核细胞个数等进行分析,在组间进行Mann-Whitney U分析,采用多变量Logistic回归模型对嗅觉障碍的影响因素进行相关性分析。结果：在嗅觉障碍影响生活质量组中伴鼻息肉、伴变应性鼻炎、有前期手术史的患者数量及血清总IgE水平、水肿评分均明显高于未影响生活质量组（均P〈0.05）;性别、年龄、吸烟史、伴鼻中隔偏曲及外周血嗜酸粒细胞数、单个核细胞数在2组患者之间差异无统计学意义（P〉0.05）。多因素Logisitic分析发现血清总IgE增高、水肿评分高是影响嗅觉的危险性因素（OR=1.003、2.483,均P〈0.01）;而前期鼻部手术史是一个保护因素（OR=0.408,P〈0.01）。结论：严重的鼻腔水肿、血清总IgE增高是患者出现严重嗅觉障碍的危险因素,前期鼻部手术则是保护性因素。     

The role of allergy and smoking in chronic rhinosinusitis and polyposis

Objectives/Hypothesis: The article considers the interrelatedness of allergic rhinitis and chronic rhinosinusitis (CRS). The negative impact of perennial allergy and tobacco use on polyposis in sinus surgery patients is explored. Study Design: A retrospective chart review, performed by the first author over a 6-year period, of patients who underwent functional endoscopic sinus surgery for CRS. Methods: The subjects' allergy status and smoking history are scrutinized by summary statistics and a multiple linear logistic model for predicting the presence of polyps. Results: High prevalence of perennial allergic rhinitis (PAR) is seen in the subject population (56.4%). Both PAR and tobacco use are associated with nasal polyposis (P = .0073 and P = .0114, respectively). Conclusions: The close association of PAR and CRS suggests a possible causal link. Management of allergic rhinitis and tobacco cessation may provide greater control of chronic hyperplastic rhinosinusitis.     

Functional endoscopic sinus surgery in children: predictive factors of outcome

The main objective of this study is to assess the results of functional endoscopic sinus surgery in children and to determine which factors independently influence the postoperative results. It is a prospective study by Mansoura University Hospital. 87 patients with different applications of pediatric endoscopic sinus surgery (PESS) chronic rhinosinusitis (CRS) with nasal allergy (45 patients), CRS without nasal allergy (36 patients) and CRS with polypsis (6 patients) from 2005 to 2010 were included. All children underwent endoscopic sinus surgery. All patients were clinically, radiologically and endoscopically monitored. In this study, the overall success rate was 87.69%, the success rate for CRS with nasal allergy was 87.5%, the success rate for CRS without nasal allergy was 85.7% and the success rate for CRS with polyposis was 93%. Regarding the patients’ age, it could affect the surgical score value (X ² = 9.446 and P* = 0.009). There was significant relation between type of the preoperative disease extent, adenoidectomy, second look operation and postoperative improvement. There was no significant relation between type of the preoperative disease or previous surgery and postoperative improvement. In conclusion, postoperative improvement was significantly correlated with extent of preoperative disease, adenoidectomy and second look operation and not significantly correlated with type of the preoperative disease or previous surgery. The results of PESS are influenced by age group, a younger age group is associated with more adhesions and recurrences and an older age group is associated with blood loss and higher surgical score. All these variables are contributing in the outcome of PESS.     

Type 1/type 2 inflammatory cytokines correlate with olfactory function in patients with chronic rhinosinusitis

BackgroundOlfactory dysfunction secondary to chronic rhinosinusitis (CRS) has been highly associated with impaired quality of life. Asian CRS patients showed a distinct inflammatory profile, with less type 2 endotype compared with European and North American. This study aimed to explore the pattern of the inflammatory cytokines in CRS patients from China and their association with olfactory function.MethodsInstitutional review board-approved prospective study in which the olfactory function of 71 CRS patients was assessed with Sniffin' Sticks before the nasal endoscopic surgery. A set of cytokines and inflammatory mediators including type 1 and type 2 inflammatory cytokines were measured in nasal mucus by using a multiplex flow cytometric bead assay (CBA). Baseline characteristics in CRS patients were collected and the Spearman r statistic was performed to assess the association of olfactory function with cytokines and inflammatory mediators.ResultsA total of 71 nasal mucus samples of CRS patients, including 25 chronic rhinosinusitis without nasal polyposis (CRSsNP) patients and 46 chronic rhinosinusitis with nasal polyposis (CRSwNP) patients, were evaluated in this study. The nasal mucus levels of type 1 inflammatory cytokine IFN-γ (interferon-γ), type 2 inflammatory cytokines including IL-4, IL-5 and GM-CSF (granulocyte-macrophage colony-stimulating factor) and anti-inflammatory cytokine IL-10 were significantly and inversely correlated with olfactory function in total patients with CRS (r = −0.308, p = 0.009; r = −0.250, p = 0.036; r = −0.399, p = 0.001; r = −0.269, p = 0.023; r = −0.273, p = 0.021, respectively). In CRSsNP, the olfactory function was inversely correlated with levels of type 1 inflammatory cytokine TNF-α (tumor necrosis factor-α) (r = −0.637, p = 0.001) and IL-10 (r = −0.468, p = 0.018). Nevertheless, the olfactory function in CRSwNP was inversely correlated with type 2 inflammatory cytokines including IL-4 (r = −0.303, p = 0.041) and IL-5 (r = −0.383, p = 0.009).ConclusionBoth type 1 and type 2 inflammatory cytokines may contribute to the pathogenesis of CRS-associated olfactory dysfunction in the Chinese population.     

Abhängigkeit des uni- und bilateralen Riechvermögens von der nasalen Strömung bei Patienten mit chronischer Rhinosinusitis

OBJECTIVE: Olfactory dysfunction is a common finding in patients with chronic rhinosinusitis (CRS). The aim of this study was to investigate the relationship between olfaction and nasal flow as determined by active anterior rhinomanometry (AAR). METHODS: Thirty patients with CRS were included in this series. Patients' histories and subjective assessments of olfaction were documented with questionnaires. Smell tests, assessments of olfaction, AAR, and results of rhinoscopy were recorded, including odor identification, discrimination and thresholds measured with the "Sniffin' Sticks"-test. RESULTS: CRS influenced olfactory performances variably in the different tests: 10% of the patients had pathologic rates of odor discrimination, compared with 34% in odor identification and 73% in thresholds. Statistical analyses (using Spearman's test) indicated a significant correlation between nasal airflow and odor identification screening (r29 = 0.56, P < 0.01) and n-butanol-threshold (r29 = 0.44, P < 0.05), respectively. CONCLUSION: Olfactory performance in CRS was correlated to several parameters of nasal airflow measured with AAR. The n-butanol threshold test revealed the most frequent pathological results and may best be used for detecting olfactory disorders. However, because a number of factors may influence olfactory dysfunction in CRS, our findings must be evaluated in a lager series.     

Human papillomavirus and risk of oral cancer

Although human papillomavirus (HPV), a sexually transmitted virus, is established as a necessary cause for more than 95% of cervical carcinomas, the association with oral squamous cell carcinoma is less well delineated. The purpose of this study was to determine the frequency and types of HPV in squamous cells of a group of patients with newly diagnosed oral or pharyngeal cancer (n = 93) compared with an age-and gender-frequency-matched control group of patients with no history of oral cancer (n = 205). HPV was evaluated from a mouth rinse collection of cells in the oral cavity and tested by ³²P-labeled HPV generic probes and DNA sequencing for HPV types. HPV was identified in 15% of the oral cancer cases but in fewer than 5% of the controls (P < .05). The risk of cancer associated with HPV infection was independent of tobacco and alcohol use (adjusted odds ratio [OR] = 3.70; 95% confidence interval [CI]: 1.47–9.32; P < .05). HPV types included similar and other types not identified previously in the genital tract. There was no statistically significant increased risk of cancer among former tobacco users (former vs. never users: adjusted OR = 0.67, 95% CI: 0.31–1.44, P < .05), but the risk was significantly increased for current users (current vs. never: adjusted OR = 2.63; 95% CI: 1.22–5.71; P < .05). Likewise, former alcohol users were not at increased risk of disease (former vs. never: adjusted OR = 1.78; 95% CI: 0.87–3.67), whereas current alcohol users were (current vs. never: adjusted OR = 2.57; 95% CI: 1.22–5.42; P < .05). HPV-related genital lesions (14.3% vs. 10.6%), oral-genital sexual behavior (42.4% vs. 45.2%), and number (11 or more) of sexual partners (23% v. 17%) were not significantly different between cases and controls. These data suggest that in addition to tobacco and alcohol, HPV plays a role in the development of oral cancer.     

Risk factors for olfactory dysfunction in chronic rhinosinusitis

Objective

Although risk factors for olfactory dysfunction in patients with chronic rhinosinusitis (CRS) have been examined, most studies did not distinguish between classified eosinophilic chronic rhinosinusitis (ECRS) and noneosinophilic chronic rhinosinusitis (NECRS). The incidence of eosinophilic disease in Japan differs from that in the West. Thus, when olfaction in CRS is investigated, ECRS and NECRS should be examined separately. In the present study, we examined the clinical characteristics associated with olfactory dysfunction in Japanese patients with ECRS and NECRS enrolled in a large multicenter, prospective cohort study.

Methods

Olfactory examination results, demographic data, clinical factors, and comorbidity data were analyzed for 418 patients with CRS at 3 tertiary care centers. We used T&T olfactometry, intravenous olfactory test (the Alinamin test) and Likert scale to assess subjects’ olfactory function. Data were analyzed with univariate and multivariate analyses.

Results

Olfactory dysfunction was more severe and more prevalent in ECRS than in NECRS. We found that olfactory cleft polyps (odds ratio [OR], 3.24), ethmoid opacification (OR, 2.64), asthma (OR, 2.29), current smoking (OR, 1.74) and age ≥50 years (OR, 1.66) were associated with olfactory dysfunction in CRS. Ethmoid opacification (OR, 3.09) and olfactory cleft polyps (OR, 3.05) were associated with olfactory dysfunction in NECRS. Olfactory cleft polyps (OR, 3.98), current smoking (OR, 2.67), IgE ≥400 IU/ml (OR, 2.65), ethmoid opacification (OR, 2.51), and asthma (OR, 2.34) were associated with olfactory dysfunction in ECRS.

Conclusions

Olfactory dysfunction was more severe and prevalent in ECRS than in NECRS. Physician should pay attention to these clinical findings to diagnose olfactory dysfunction, especially in ECRS, and should provide appropriate explanation, guidance, and care. In addition, smokers should be advised to stop smoking to help prevent olfactory dysfunction.

Chronic rhinosinusitis and endoscopic sinus surgery

Olfactory dysfunction is a major symptom reported by patients with chronic rhinosinusitis (CRS). Surgical treatment of this disease requires close surveillance of such dysfunction because of wide ranging implications for safety, quality of life, and impact on the flavor of foods and beverages. This review highlights key findings regarding the influences of endoscopic sinus surgery (ESS) on olfactory function across the unique presentations of CRS. Such findings provide information useful for informing patients of potential complications and for obtaining informed consent prior to surgical intervention. ESS has been shown to improve olfaction across all types of CRS as assessed through quantitative testing and subjective reports. The presence of nasal polyposis (NP) and eosinophilia have been identified as predictors of significant postoperative olfactory improvement. When indicated, judicious partial resection of the middle turbinate may result in improved olfactory function without a risk of long term complication. Careful attention to the olfactory cleft and frontal sinus recess are important in limiting olfactory complications by avoiding indiscriminate disruption of olfactory epithelium. Given the chronic nature of the disease, surveillance of olfactory function in patients with CRS is a lifelong activity that will evolve as emerging technologies become available.     

Endoscopic versus microscopic trans‐sphenoidal pituitary surgery: a systematic review and meta‐analysis

Clin. Otolaryngol. 2011, 36 , 212–220 Background: Endoscopic trans‐sphenoidal surgery has been increasingly replacing microscopic surgery as the state of the art trans‐sphenoidal approach. Objective of review: To assess the efficacy and safety of pure endoscopic approach in comparison with microscopic approach in pituitary surgery. Type of review: Literature review and meta‐analysis. Search strategy: Systematic literature searches of MEDLINE (1952–10th February 2010), EMBASE (1974–10th February 2010) and the Cochrane Central Register of Controlled Trials to the 10th February 2010. Evaluation method: Review of all English‐language studies comparing endoscopic and microscopic techniques. Results: Eleven relevant studies were identified with a total of 806 patients, 369 of whom had endoscopic surgery and 437 microscopic surgery. The initial remission rate of hypersecretion of functioning adenomas was not significantly different between the endoscopic and the microscopic group [(OR: 1.34(95% CI: 0.73–2.47); P = 0.35; 66% remission rate in endoscopic group versus 60% in microscopic)].The proportion of patients with complete tumour removal was not significantly different in the endoscopic group than in the microscopic group [(OR: 0.83, (95% CI: 0.52–1.33); P = 0.44]. The rate of CSF leak attributable to the surgical method did not differ significantly between endoscopic and microscopic group. Post‐operative diabetes insipidus was less frequent in those having endoscopic surgery [15%versus 28%P = 0.003]. Regarding the other intra cranial and nasal complications attributable to surgical technique, the occurrence rate in endoscopic group was significant lower compared with microscopic group (13%versus 1.2% respectively, P < 0.05). Patients in the endoscopic group had significant shorter postoperative hospital stay with a range from 3.7 to 4.4 days, than those of microscopic group with a range from 5.4 to 5.7 days [(WMD: ?1.53, (95% CI: ?2.30 to ?0.77); P < 0.00001)]. Conclusions: Notwithstanding its limitations, the present systematic review, based on the currently available evidence, suggests that endoscopic trans‐sphenoidal pituitary surgery is associated with similar rates of complete tumour excision and remission rates. Endoscopic surgery was associated with fewer complications related to surgical technique and a shorter hospital stay.     

Facial pain/headache before and after surgery in patients with nasal polyposis

Conclusion: Endoscopic surgery improved facial pain/headache and physical-psychosocial impacts in patients with nasal polyposis. However, one fifth of patients still experienced residual pain after surgery, requiring neurologic counseling to look for the non-sinonasal cause of their symptoms. Objective: Considering the limited amount of literature on facial pain/headache in patients with nasal polyposis, this prospective study assesses facial pain/headache and its impacts on the quality-of-life (QoL) before and after endoscopic surgery. Methods: Facial pain/headache was assessed, using the DyNaChron questionnaire, in 107 patients with nasal polyposis 1 day prior to surgery and 6 weeks after surgery. All patients were operated on endoscopically on the bilateral ethmoidal labyrinths and olfactory clefts. Results: Moderate or severe facial pain/headache was reported by 50% of the patients before surgery and by 20% after surgery. Post-operatively, 79.44% of patients reported no/very mild pain (vs 47.66% pre-operatively) and 20.56% moderate/severe pain (vs 52.33% pre-operatively). The pain was statistically reduced after surgery among patients with previous surgery (p = 0.0006). The scores of all analysed impacts of pain improved after surgery. However, patients with grade 1 polyps seemed to have less benefit from the surgery for facial pain/headache than those with more severe nasal polyposis.     

Analysis of the clinical effect of olfactory training on olfactory dysfunction after upper respiratory tract infection

Background: Olfactory dysfunction is a common symptom during otolaryngology outpatient service.

Objective: To explore the clinical effect of olfactory training on olfactory dysfunction after upper respiratory tract infection (URTI), and its influence factors.

Material and methods: A total of 60 confirmed cases of URTI-induced olfactory dysfunction were enrolled into the present study. The olfactory training lasted for 24 weeks. These patients were tested using Sniffin’ Sticks and threshold-discrimination-identification (TDI) composite scoring before treatment, and at 1, 3 and 6 months after treatment.

Results: It was found that URTI-induced olfactory dysfunction patients had more evident deterioration in odor identification ability. The effective rates of olfactory training on olfactory dysfunction at 1, 3 and 6 months after treatment were 1.67%, 26.67% and 41.67%, respectively. The TDI scores at the 3rd and 6th months, but not at the 1st month, were significantly higher, when compared to those before treatment. The course of diseases was a significant influence factor on the therapeutic effect of olfactory training (OR = 0.805, 95% CI: 0.696–0.931).

Conclusions: Olfactory training can efficiently cure URTI-induced olfactory dysfunction, and in particular, significantly improve the odor discrimination ability and odor identification ability.

Significance: Providing useful data for further research regarding olfactory dysfunction.     

A randomized double‐blind study to compare the effects of nasal fluticasone and betamethasone on the hypothalamo–pituitary–adrenal axis and bone turnover in patients with nasal polyposis

Treatment of nasal polyposis with topical betamethasone is associated with suppression of the hypothalamo–pituitary–adrenal (HPA) axis and, potentially, has adverse effects on bone turnover. Fluticasone propionate is a potent corticosteroid with negligible absorption across the nasal mucosa and extensive first‐pass hepatic metabolism. We performed a randomized double‐blind study, in patients with nasal polyposis, comparing the effects of 8 weeks' treatment with betamethasone drops or fluticasone nasules on the HPA axis using the 1 µg tetracosactide test, and on bone turnover using two serum markers. Nine patients were allocated to each treatment. Betamethasone resulted in significant suppression in the tetracosactide test (P = 0.006), but fluticasone did not (P = 0.113). There were no differences in bone turnover or treatment efficacy between treatments. Treatment of nasal polyposis with topical betamethasone drops, but not with fluticasone nasules, suppresses the HPA axis and, given comparable efficacy, fluticasone administered via nasule should be the preferred agent.     

Clinical significance of olfactory event-related potentials related to orthonasal and retronasal olfactory testing

OBJECTIVE: The purpose of this study was to evaluate the likelihood of recording olfactory event-related potentials (OERPs) in patients with an olfactory dysfunction and to correlate the electrophysiological responses to orthonasal and retronasal olfactory testing. DESIGN/MATERIALS AND METHODS: This was a prospective study of 65 patients with different origins of their olfactory loss. Orthonasal olfactory function was assessed with the "Sniffin' Sticks" test (orthonasal score; maximal score 48) and retronasal olfactory function with odorized powders presented intraorally (retronasal score; maximal score 20). The OERPs were obtained after presentation of 2-phenyl ethyl alcohol, the selected olfactory stimulus. Causes of olfactory dysfunction included postinfectious olfactory loss (n = 15), head trauma (n = 26), nasal polyposis (n = 15), and mixed causes (idiopathic, toxic, drug induced) (n = 9). RESULTS: Based on orthonasal testing, 32 and 33 patients were diagnosed with anosmia and hyposmia, respectively. Twenty-two patients from the hyposmic group demonstrated reliable OERPs. No OERPs were recorded in the anosmic group. Prevalence of OERPs in a cohort of patients with olfactory dysfunction was 33.8% (22 of 65). Median score (expressed as the percentage of the maximal score that could be obtained theoretically) in which OERPs were recorded was 50% (24 of 48) with orthonasal testing and 80% (16 of 20) with retronasal testing. CONCLUSIONS: Patients with olfactory dysfunction usually demonstrate OERPs in one third of the cases. When olfactory dysfunction is in the range that separates normosmic subjects from anosmic patients, patients may have identifiable OERPs. Interpretation of both orthonasal and retronasal psychophysical olfactory testing should be supported by the recording of OERPs in a clinical setting.     

The increase in incidence of cancer of the tongue in the Nordic countries continues into the twenty-first century

Conclusions This study shows that heavy drinking is a risk factor for prolonged delay in presenting with head and neck cancer and for presenting with a large tumour in the head and neck region. Excessive smoking is only a risk factor for being diagnosed with a large tumour, although there is a weak association between smoking and prolonged diagnostic delay.

Objective It is reasonable to assume that prolonged delay in presenting with head and neck cancer is associated with an advanced stage of cancer at diagnosis. In this study we analysed the effects of drinking and smoking habits on diagnostic delay and the T stage of the tumour at diagnosis.

Material and methods A total of 427 patients with newly diagnosed head and neck carcinomas were eligible for this study. Of these, 306 (72%) actually participated: 134 (77%) with an oral tumour; 117 (69%) with a larynx tumour; and 55 (65%) with a pharynx tumour. Diagnostic delay was defined as a period of >30 days between the appearance of the first tumour-related symptoms and the first visit to a physician. T3–4 tumours were defined as advanced tumours. Drinking behaviour was classified into three types: light (0–2 drinks/day); moderate (3–4 drinks/day); and heavy (>4 drinks/day). Smoking habits were classified into 4 types: never; stopped; light (0–20 cigarettes/day); and heavy (>20 cigarettes/day).

Results Logistic regression showed that there were significantly more heavy than light drinkers [p=0.04; odds ratio (OR) 1.8; 95% CI 1.0–3.1] in the delay group than in the non-delay group. Light smokers showed a tendency towards prolonged delay (p=0.06; OR 2.2; 95% CI 1.0–5.0). Both heavy drinking (p=0.01; OR 2.0; 95% CI 1.2–3.6) and heavy smoking (p=0.03; OR 3.1; 95% CI 1.1–8.4) were risk factors for a patient to be diagnosed with a large tumour.     

The effects of endoscopic sinus surgery on level of fatigue in patients with chronic rhinosinusitis

BACKGROUND: Fatigue is a common symptom of chronic rhinosinusitis (CRS), but the response of fatigue to endoscopic sinus surgery (ESS) is rarely studied. METHODS: A prospective, open cohort of adult patients undergoing ESS for CRS was studied using 10-cm fatigue visual analog scales (VASs), Lund-MacKay computed tomography (CT), and Lund-Kennedy nasal endoscopy scoring. RESULTS: Two hundred seventy-two patients, followed for a mean (+/-SD) of 16.5 +/- 8.5 months after ESS, noted significant fatigue improvement with an effect size defined as large by Cohen (0.8 [95% CI, 0.5-1.3]). Neither preoperative CT scores nor preoperative endoscopy scores correlated with preoperative fatigue severity. Compared with the mean preoperative fatigue score (6.1 +/- 2.9 cm), preoperative fatigue was more severe in women (6.9 +/- 2.6 cm; p < 0.001) patients with depression (7.7 +/- 2.4 cm; p < 0.001) and patients with fibromyalgia (7.9 +/- 2.2 cm; p = 0.013), but less severe in patients with nasal polyposis (5.4 +/- 3.2 cm; p = 0.009). Significantly greater postoperative reduction in fatigue was noted in patients with fibromyalgia when compared with study patients without fibromyalgia (effect size = 1.8 [95% CI, 1.6-2.2]; p > 0.001) with final fatigue severity scores similar to the entire study group. Similarly, patients with severe fatigue (n = 112; mean VAS score, 8.8 +/- 0.8 cm) showed a more pronounced improvement than patients less severely fatigued (n = 160; mean VAS score 4.2 +/- 2.4 cm; effect size = 2.2 [95% CI, 2.0-2.9]; p > 0.001). CONCLUSION: Fatigue improves after ESS, with significantly greater improvement in patients with fibromyalgia and in patients that are more severely fatigued at presentation.     

Diffuse nasal polyposis and endonasal endoscopic surgery: long-term results, a 65-case study

OBJECTIVE: To analyze the efficacy of a standardized surgical procedure in patients with nasal polyposis. STUDY DESIGN: Prospective study of nonrandomized cases from a single institution. METHODS: An inception cohort of 65 consecutive patients with nasal polyposis observed from January 1994 to December 1997. Presence of asthma, allergies, or aspirin intolerance, duration of nasal polyposis, previous surgery, and medical treatment were noted. Clinical symptoms were evaluated with a visual analogue scale (VAS), and a preoperative computed tomography scan was performed before the surgical procedure. At the end of the study, an evaluation was performed to collect all information concerning nasal symptoms, asthma conditions, quality of life, and patient's opinion about this type of surgery. RESULTS: Sixty patients have completed the study. Polyposis was isolated in 29 patients (group A), asthma was present in 21 patients (group B), and aspirin intolerance in 10 patients (group C). Nasal obstruction (n = 53/60, 88.3%) and olfactory disturbances (n = 54/56, 96.4%) were the main preoperative complaints, according to the VAS, with a high degree of severity. No significant difference for nasal symptomatology was found between the three groups. Nasal obstruction and olfactory dysfunction was improved in 37 and 42 patients, respectively, without a statistical significance between the groups. A reduction of the antiasthmatic treatment was observed in 24 of 31 patients. A massive and anteriorly localized recurrence was noted in 3 and 19 patients, respectively. CONCLUSIONS: Endoscopic sphenoethmoidectomy is indicated for nasal polyposis refractory to intensive medical management with a good improvement of patient's quality of life.
