Comparison of plain radiographs, coronal CT, and intraoperative findings in children with chronic sinusitis.

Evaluating the extent of chronic sinusitis in children is critical in management of the disease and determination of the need for surgery. High-resolution computed tomography can demonstrate disease that is not shown on routine x-ray films. It can also delineate pathologic variations and demonstrate inaccessible anatomic structures. We compared plain radiographs, CT scans, and intraoperative findings for 300 pediatric patients with chronic or recurrent sinusitis. Despite an imperfect record in demonstration of sinus disease in all of our patients, computed tomography was unquestionably better than plain radiography in diagnosis of chronic sinusitis and evaluation of the need for surgery. Despite its superior performance, CT should not be used exclusively to diagnose disease or propose surgery. These determinations must be made on the basis of a combination of the patient's symptoms, physical examination findings, and CT results.

A retrospective analysis of treatment outcomes and time to relapse after intensive medical treatment for chronic sinusitis.

BACKGROUND: Despite the high prevalence of chronic sinusitis, there are few published studies assessing its response to medical treatment. We analyzed, retrospectively, 40 patients seen in our center who were treated for chronic sinusitis with a protocol of intensive medical therapy. Both symptomatic and radiographic improvements were assessed as well as factors associated with early relapse. METHODS: Intensive medical treatment consisted of 1 month of antibiotics, a short course of oral steroids, and adjunctive therapy (e.g., nasal irrigations plus intranasal steroids). After intensive medical therapy, adjunctive medical therapy was continued. A sinus computed tomography was performed at baseline and 6-8 weeks later and scored for extent of disease. Pre- and posttreatment symptom scores also were assessed. Time to relapse was defined as the time interval after antibiotic treatment at which a recurrence of symptoms necessitated reinstitution of antibiotics and/or oral steroids. RESULTS: Thirty-six of the 40 patients improved either symptomatically, radiographically, or both following the medical regimen. Twenty-six patients had sustained symptomatic benefit beyond 8 weeks after initial treatment. A statistically significant correlation was found between the change in pre- to posttreatment symptom scores and computed tomography scores. Using a log-rank test to compare rates of sinusitis relapse, nasal polyposis and a history of sinus surgery were significantly associated with earlier relapse (p = 0.006 and 0.018, respectively). In contrast, atopy, asthma, and persistent obstruction of the ostiomeatal unit were not associated with early relapse. CONCLUSION: Intensive medical treatment resulted in symptomatic and radiographic improvement in chronic sinusitis, and the majority of patients remained free of a relapse for >8 weeks. A history of nasal polyposis or previous sinus surgery was associated with earlier relapse of sinusitis symptoms. In contrast, the presence of atopy, a history of asthma, or persistent OMU obstruction was not associated with earlier relapse. Although long-term benefits have not been established, a prospective study of treatment outcomes from intensive medical treatment appears to be warranted.

Longitudinal sensitivity of generic and specific health measures in chronic sinusitis.

The utility of reliable health measures for longitudinal studies in chronic sinusitis depends on their ability to detect clinically relevant change. Sixty-three patients with chronic sinusitis were evaluated before and three months after ethmoid sinus surgery using the Chronic Sinusitis Survey (CSS) and the generic Short-Form 36-Item Health Survey (SF-36). Statistically significant improvement was found for several SF-36 subscales including physical functioning, role functioning-physical, bodily pain, vitality and all CSS subscales. However, the differences between the instruments in longitudinal sensitivity to change as measured by standardized response means (SRM) and effect sizes (ES) were large. For the SF-36, sensitivity to change ranged from minimal to small (SRM: 0.01-0.43; ES: 0.01-0.52) with bodily pain and role functioning-physical scores most sensitive. For the CSS, sensitivity to change ranged from moderate to large (SRM: 0.56-0.82; ES: 0.48-1.12) with symptom-based and total index scores most sensitive. Despite this, the SF-36 yielded useful information concerning the relative burden of chronic sinusitis and failure of these patients to achieve normal levels of general health 3 months after sinus surgery. We conclude that the disease-specific CSS was more sensitive to change than the SF-36 survey in patients following ethmoid sinus surgery.

Outcome in patients with chronic sinusitis after the minimally invasive sinus technique.

BACKGROUND: Controversy persists regarding the use of minimally invasive sinus techniques (MIST) to treat chronic sinusiris primarily because of an absence of comparative outcome data. METHODS: In this prospective study of 85 patients with chronic sinusitis treated surgically with MIST, the long-term postoperative outcome was assessed using the duration-based Chronic Sinusitis Survey (CSS) quality of life instrument. Patient age ranged from 4 to 81 years old (mean age, 42 +/- 16.7 years). Forty-three subjects were male patients and 42 were female patients. Mean follow-up time was 23.8 +/- 2.2 months. RESULTS: At follow-up, there was a 124.0% improvement in the mean CSS symptom score (p < 0.00001), a 30.1% improvement in the mean CSS medication score (p < 0.00001), and a 62.0% improvement in the mean CSS total score (p < 0.00001). An overall improvement was found in 78.8% of patients; 12.9% of patients were worse and 8.2% of patients were unchanged. Thirty-four patients (40.0%) had postsurgical CSS total scores within the normative interquartile range obtained in healthy controls. Twenty-six of these patients had postsurgical scores that actually surpassed the mean normative CSS total score. Before follow-up evaluation, 5 of the 85 patients (5.9%) had revision surgery after the initial procedure. All had revision MIST procedures and all were found to have an overall improvement at the time of follow-up. CONCLUSION: We conclude that MIST significantly improves the outcome in patients with chronic sinusitis and should strongly be considered as the initial surgical option for such patients.

A double-blind comparison of ciprofloxacin and amoxycillin/clavulanic acid in the treatment of chronic sinusitis.

A total of 251 adults with chronic sinusitis were enrolled into this prospective multicentre, double-blind, double-placebo comparison of ciprofloxacin (500 mg twice daily) with amoxycillin/clavulanic acid (500 mg three times daily). The diagnosis of chronic sinusitis (persistence of clinical symptoms for at least 3 months) was confirmed by computerized tomography scan and/or sinusoscopy prior to therapy. Patients at inclusion had purulent or muco-purulent rhinorrhoea. Staphylococcus aureus (n = 45), Haemophilus influenzae (n = 35), Streptococcus pneumoniae (n = 32) and enterobacteriaceae (n = 31) were isolated from pre-treatment aspirates of the middle meatus. Treatment lasted 9 days, at the end of which nasal discharge disappeared in 71/118 (60.2%) patients of the ciprofloxacin group and 69/123 (56.1%) of those in the amoxycillin/clavulanic acid group. The clinical cure and bacteriological eradication rates were 58.6% versus 51.2% and 88.9% versus 90.5% for ciprofloxacin and amoxycillin/clavulanic acid, respectively. These differences were not significant, however, amongst patients who had a positive initial culture and who were evaluated 40 days after treatment. Ciprofloxacin recipients had a significantly higher cure rate than those treated with amoxycillin/clavulanic acid (83.3% vs. 67.6%, p = 0.043). Clinical tolerance was significantly better with ciprofloxacin (p = 0.012), essentially due to a large number of gastro-intestinal related side-effects in the amoxycillin/clavulanic acid group (n = 35). Ciprofloxacin proved to be at least as effective as amoxycillin/clavulanic acid. The superior safety profile, a twice daily dosage regimen, suggests that ciprofloxacin may be a useful therapeutic alternative for the treatment of chronic sinusitis.

Mode of action of long-term low-dose macrolide therapy for chronic sinusitis in the light of neutrophil recruitment.

Chronic sinusitis is a common inflammatory upper respiratory tract disease. One of the prominent features of this disease is persistent purulent effusion containing numerous emigrated neutrophils in the paranasal sinuses. Recent advances in sinusitis research have revealed two positive feedback mechanisms that explain the chronic neutrophil accumulation in the sinus. First, interleukin (IL)-1beta secreted by monocytes, macrophages and fibroblasts upregulates the expression of E-selectin and intercellular adhesion molecule-1 (ICAM-1) in vascular endothelial cells, and thereby induces the extravascular transmigration of neutrophils. The emigrated neutrophils then secrete IL-1beta, which amplifies the expression of E-selectin and ICAM-1, resulting in further neutrophil infiltration. Second, chemoattractants including IL-8 in the sinus effusion initiate neutrophil exudation. Emigrated neutrophils then secrete IL-8, which elicits further neutrophil accumulation in the sinus effusion. Long-term low-dose macrolide therapy was first introduced for the treatment of diffuse panbronchiolitis in the 1980's. In the 1990's it was also shown to be an effective treatment for chronic sinusitis. The inhibitory effect of macrolides on neutrophil infiltration in inflammatory sites has been well documented in these diseases. Several lines of evidence indicate that macrolides do not function simply as a bactericide. In vitro studies have demonstrated various effects of macrolides on immunocompetent cells, inflammatory cells and airway epithelial cells. It has been shown that macrolides inhibit the production of IL-8 and IL-1beta and the expression of ICAM-1, suggesting that macrolides block the aforementioned dual positive feedback system of neutrophil recruitment and thereby exert their clinical efficacy in the treatment of chronic sinusitis. The inhibitory effects of macrolides on multiple steps in the process of neutrophil recruitment are presumably mediated by the inhibition of transcription factors such as nuclear factor-kB and activator protein-1. Further investigation of the mode of action of macrolides at the molecular level would lead to the development of safer and more effective drugs for the treatment of chronic sinusitis. In addition, the possible risk of this therapy such as the occurrence of resistant strains have to be carefully surveyed hereafter.

[The effect of proinflammatory cytokines in pathogenesis of chronic sinusitis].

OBJECTIVE: To investigate the effect of the proinflammatory cytokines, including IL-1, IL-8 and TNF in the pathogenesis of chronic sinusitis. METHOD: Using immunohistochemical streptavidin-biotin peroxide complex (SABC) method to investigate the expression of interleukin-1 (IL-1), IL-8 and tumor necrosis factor (TNF) in the local mucosa of the two type chronic sinusitis. RESULT: There were significantly large numbers of IL-1+, IL-8+ and TNF+ cell in chronic sinusitis type I compared with healthy control (P < 0.01). The numbers of IL-8+ and TNF+ cell in the chronic sinusitis type II were significantly larger than that in the healthy control (P < 0.01). The numbers of IL-1+ cell in chronic sinusitis type I were significantly larger than that in chronic sinusitis type II (P < 0.01). CONCLUSION: This study indicates that proinflammatory cytokines may play an important role in the pathogenesis of chronic sinusitis. It appears that specific cytokine patterns are found in different forms of sinusitis. The investigation of different cytokine patterns may help to understand the different pathogenesis in chronic sinusitis subgroups.

The health impact of chronic sinusitis in patients seeking otolaryngologic care.

Although chronic sinusitis is an increasingly common diagnosis in the United States, the health burden of this disorder relative to the general population and to other chronic diseases has not been previously evaluated. One hundred fifty-eight patients with chronic sinusitis and no prior surgery underwent cross-sectional evaluation by use of the Medical Outcome Study Short-form 36-Item Health Survey. These patients were all referred for otolaryngologic care, and more than 80% subsequently underwent sinus surgery. Mean scores were compared from the eight subscales of general health assessment with similarly derived data for the United States general population. Significant differences (p < 0.05) were seen in several domains, including bodily pain, general health, vitality, and social functioning. Comparisons with other chronic diseases revealed significantly lower scores (p < 0.05) in measures of bodily pain and social functioning for sinusitis patients than in patients with congestive heart failure, angina, chronic obstructive pulmonary disease, and back pain. These findings suggest that the national health impact of chronic sinusitis is far greater than is currently appreciated.

Intractable pediatric chronic sinusitis with antrochoanal polyp.

It has been reported that pediatric chronic sinusitis with antrochoanal polyp is difficult to cure because it tends to recur easily even with surgery. Therefore, in order to improve its cure rate, aggressive treatment combining polypectomy, intra-maxillary intubation through the inferior meatus, macrolide administration, etc., was attempted. Thirty-seven sides of pediatric chronic sinusitis with antrochoanal polyp and 44 sides of chronic sinusitis without polyp were evaluated after the same treatments. The mean age of patients was 9.7 years, and the mean intubation period was 20 months. Since subjective improvements in children are questionable, the efficacy was evaluated strictly on the basis of X-ray alone focusing on the maxillary sinus. Twenty-four percent of the group with antrochoanal polyp showed 'excellent' effect, i.e. almost complete resolution of the sinus findings, while 45% of the group without polyp showed 'excellent' effect, with a mean follow-up period of 3 years and 6 months. This difference was significant (P<0. 01, chi(2)-test). These results further document the intractableness of chronic sinusitis with choanal polyp in children.

[Chronic sinusitis among family members of patients with diffuse panbronchiolitis].

The frequency of chronic sinusitis among the family members of 26 patients with diffuse panbronchiolitis were analyzed, and were compared with the frequency in 127 control families. In the diffuse panbronchiolitis group, 50% of families suffered from chronic sinusitis, in contrast to 18.9% of families in the control group. The difference was significant. Analysis of HLA antigens in families of patients with diffuse panbronchiolitis revealed that family members with chronic sinusitis had the same HLA haplotype as these patients with diffuse panbronchiolitis in the same family. These results indicate that patients with chronic sinusitis only and those with diffuse panbronchiolitis have similar genetic background. They also suggest that the patients with chronic sinusitis may be seen as a mild or incomplete type of diffuse panbronchiolitis.

Methacholine bronchial hyperresponsiveness in chronic sinusitis.

The coexistence of chronic sinusitis (CS) may deteriorate the clinical condition of lower airway diseases such as bronchial asthma (BA) or chronic bronchitis (CB). However, the bronchial hyperresponsiveness (BH) in CS without any apparent lower airway disease is not fully understood nor are the effects of treatment. We examined lower airway hyperresponsiveness to methacholine (MCh) in 42 subjects with CS but without allergic rhinitis (AR) who had normal lung functions without any pulmonary symptoms, comparing it with that of 50 subjects with stable BA, 50 subjects with simple CB and 40 subjects with AR, and further examined the effect of endoscopic sinus surgery in 7 CS subjects with BH. The BH to MCh was measured in terms of the minimum dose (Dmin), defined as the cumulative dose at the point where respiratory conductance began to decrease. A Dmin <50 units was defined as BH. Seventy-one percent of CS subjects showed BH without relation to the severity or duration of CS, or atopic status. BH in CS subjects, which was less than that in BA subjects, was similar to that in simple CB or AR in both its prevalence and degree. After the surgical treatment of CS, BH significantly decreased (p < 0.01) with improvements in both nasal symptoms and sinus lesions. These findings suggest that CS itself induces BH to a degree similar to simple CB and AR without any relationship to the clinical background, and that adequate treatment of CS reduces BH.

Translation and validation assessment of the Chinese version of the chronic sinusitis survey.

BACKGROUND: The Chronic Sinusitis Survey (CSS) is a valid, disease-specific measure for evaluating the health status and treatment effectiveness of adults with chronic rhinosinusitis (CRS). In this study, we developed a Chinese version of the CSS (CCSS) which provides the psychometric properties of the Chinese CSS. METHODS: The CSS was translated into Chinese using a parallel model. The CCSS was administered to 198 patients in a prospective manner, and was validated in order to establish its reliability and validity. RESULTS: The CCSS demonstrated good test-retest reliability (correlation coefficient = 0.6-0.89, p=0.0001) and internal consistency (Cronbach's alpha =0.76). The CCSS results were significantly correlated with bodily pain (BP), general health (GH), role-emotional (RE), and mental health (MH) subscales of the Chinese (Taiwan) version of the generic 36-item Short-Form Health Survey (TSF-36). The standardized response mean for the CCSS total score was 0.75, indicating good sensitivity to clinical change. CONCLUSIONS: This validation study demonstrates that the performance characteristics of the CCSS meet the criteria for a valid measure. The CCSS is a valid tool to evaluate adults with CRS among Mandarin-speaking populations.

Clinical and bacteriologic features of chronic sinusitis in children.

The clinical and bacteriologic aspects of chronic sinusitis in childhood were studied. Of 35 children who underwent surgical procedures for chronic sinusitis, 22 had positive bacteriologic cultures of aspirates from the sinus. The most common organisms isolated were Haemophilus influenzae, Streptococcus pneumoniae, and Branhamella catarrhalis. Five of eight S pneumoniae strains were relatively resistant to penicillin and resistant to sulfamethoxazole-trimethoprim. All of the B catarrhalis and 20% of the H influenzae organisms were beta-lactamase positive. Overall, 14 of 28 of the bacteria were penicillin resistant. In addition, all 12 children 2 years of age or younger had a positive bacterial culture as compared with much lower rates in older children. Although the incidence of S pneumoniae strains that are relatively resistant seems to be rising, to our knowledge we report the first description of these organisms as significant pathogens in chronic childhood sinusitis. These results indicate that chronic, difficult to manage sinusitis in very young children is frequently bacterial in origin, especially if the patient is 2 years old or younger. In light of the frequent failure of antibiotic therapy and considering the incidence of relatively resistant S pneumoniae strains, puncture of the sinus should be considered early in the course of chronic sinusitis to isolate pathogenic organisms and determine appropriate antimicrobial therapy.

Elevated nitric oxide metabolite levels in chronic sinusitis.

Decreased exhaled nitric oxide (NO) is found in chronic sinusitis. NO metabolites (nitrates, nitrites, and S-nitrosothiols) were measured in sinus lavages with a rabbit model of chronic sinusitis. NO metabolite levels (mean +/- SD) were 3.0+/-1.6 micromol/L in uninfected rabbits, 10.7+/-11.4 micromol/L in infected animals, and 7.6+/-5.4 micromol/L in postantrostomy recovering animals. Infected sinuses had elevated levels of NO metabolites that were statistically significant (P<0.01) when compared with uninfected sinuses. Mucociliary transport velocity was measured in uninfected (16.0+/-5.7 mm/minute), infected (5.2+/-1.3 mm/minute), and recovery phases (3.0 mm/minute). Endoscopic appearance, light and electron microscopy, and bacterial cultures improved during recovery. Elevated levels of NO metabolites were found during chronic sinusitis and began to return to normal levels during recovery. The possible link between NO in epithelial autotoxicity and host defense mechanisms warrants further investigation.

An immunohistological study of nasal and paranasal mucosa of patients with relapsing chronic sinusitis.

Mucosal specimens from patients with chronic sinusitis have been immunohistologically investigated. Secretory IgA was found decreased in type 1 (relapsing type sinusitis) whereas C3 was increased. Lysozyme was decreased or deplated in longstanding cases (type 2). Fibronectin was found both in type 1 and type 2 chronic sinusitis. It was concluded that depletion of IgA and lysozyme with activation of C3 and fibronectin interferes with the successful treatment of sinusitis.

Correlation between bacteriology and computed tomography staging for chronic sinusitis.

In this study we report on the correlation between bacteriology and disease severity staging by computed tomography (CT) for chronic sinusitis. When patients with chronic sinusitis underwent functional endoscopic sinus surgery (FESS), swab specimens were taken from the ipsilateral middle meati and ethmoid sinuses under endoscope guidance. The severity of chronic sinusitis was evaluated by pre-operative CT scans. The CT scans were staged by the Lund and Mackay system. The scores for the frontal, anterior ethmoid and maxillary sinuses and for the ostiomeatal complex were added. The culture rates were correlated with the added scores. Between November 1998 and January 2003, 79 pairs of specimens were collected from 79 patients whose CT scans were done within a day before FESS. The culture rates of middle-meatus specimens were moderately correlated with the scores, but those of ethmoid sinus specimens were negatively correlated with the scores. If Staphylococcus epidermidis and corynebacteria were considered normal flora, the bacteriology of the middle meatus was highly correlated with the CT scores. This study shows that culture rates of middle-meatal specimens tended to increase with the severity of chronic sinusitis.

[Orbital complications in acute and chronic sinusitis].

Orbital complications in acute and chronic sinusitis occur much more rarely than previously. Orbital and ocular symptoms are also present in chronic sinusitis: mucocele, pyocele and cholesterol granuloma. We describe 33 patients with orbital complications and analyse symptoms, diagnostic procedures and treatment options. The most frequent presenting orbital and ocular symptoms are lid oedema, proptosis, pain in orbita. We got 80% correlation in assessment of bony frame of orbita in CT and MRI with intraoperative view, in 13.3% they were false positive. Pharmacologic treatment alone was used in six patients, and 27 were treated surgically. There was one case of blindness.
