Reliability and validity study of Sino-nasal outcome test 22 (Thai version) in chronic rhinosinusitis

Background

Chronic rhinosinusitis (CRS) is one of common health conditions that affects patients’ health-related quality of life. Our purpose is to assess the reliability and validity of Thai-version of Sino-Nasal Outcome Test 22 in chronic rhinosinusitis.

Methods

Permission for translation of SNOT-22 from English language to Thai language was obtained from the developer. The translation process was done based on the international standard of translation method. A total of 80 subjects were recruited into the study and divided into two groups comprising of 50 patients with chronic rhinosinusitis and 30 healthy volunteers. Cronbach’s α and Intraclass correlation coefficient were evaluated for its reliability. Validity test was evaluated against VAS score, SF-36 (Thai version) questionnaire and CT scan (based on Lund-Mackay score). Responsiveness was assessed between pre-operative and post-operative scores in 34 patients.

Results

The Thai version of SNOT-22 showed good reliability according to high value of Cronbach’s α coefficient (r?=?0.929) and intraclass correlation coefficient (r?=?0.935). It also showed good validity by its ability to differential the patients with chronic rhinosinusitis from normal (p?<?0.001), and different severity of symptoms (p?<?0.05). In addition, the SNOT-22 Thai version also showed good responsiveness when compared between pre-operative and post-operative scores (p?<?0.001) and also well-performed in effect size calculation (1.37).

Conclusion

We demonstrated that Thai -version of SNOT-22 has good reliability and validity, suitable for evaluation of chronic rhinosinusitis symptoms together with severity of the disease and response to treatment.

Correlation between nasal mucociliary clearance time and gastroesophageal reflux disease: our experience on 50 patients

Objectives

It is increasingly suggested that gastroesophageal reflux disease (GERD) could play an important role in chronic rhinosinusitis. The aim of our study was to evaluate the nasal mucociliary clearance time in GERD patients and if any correlations could be assumed.

Methods

Fifty GERD patients endoscopically diagnosed underwent an ear, nose and throat evaluation. The saccharin test and the 20-Item Sino-nasal Outcome Test (SNOT-20) were administered to 50 participants who correspond to our inclusion criteria. The saccharin test is a validated proof to verify the nasal mucociliary clearance time and the SNOT-20 is a disease-specific, health-related quality of-life questionnaire widely used for the assessment of rhinosinusitis.

Results

Thirty-seven (74%) patients showed a significant increment in their saccharin test values in comparison with the others subjects (23.79 ± 5.58 vs 8.15 ± 2.06 min; P = 0.0001). This group of patients reported only typical gastroesophageal symptoms (GES) without any other complaint. Gastroesophageal endoscopic findings revealed some interesting and unexpected results in this subgroup. The remainder of patients considered (13/50; 26%) showed normal values for nasal mucociliary clearance time and they referred only typical extraesophageal symptoms (EES). In any case and in both groups rhinosinusitis complaints were present. The SNOT-20 test results were normal in all patients even if a significant difference for GES group could be highlighted (19.3 vs 7.4; P < 0.005).

Conclusion

This study supports the assumption of possible and important correlations between nasal mucociliary clearance time and GERD. GERD could be an altering factor for nasal function also in absence of laryngo-pharyngeal symptoms although to verify this interesting hypothesis more validated data are necessary.     

Outcome of spray cryotherapy plus functional endoscopic sinus surgery on management of healing in nasal polyposis

Background

Nasal Polyposis is a benign tumor in nasal or paranasal mucosa, which confronts difficulties in management of healing after treatments with surgery. The aim of this study was to evaluate the effects of Spray Cryotherapy (SCT) on management of healing in patients with nasal polyposis who undergone functional endoscopic sinus surgery.

Differential effects of postoperative oral corticosteroid on eosinophilic vs. non-eosinophilic CRSwNP subtypes

Purpose

The efficacy of postoperative oral corticosteroids on surgical outcomes in chronic rhinosinusitis with nasal polyps (CRSwNP) patients following endoscopic sinus surgery (ESS) remains controversial. This study evaluated the potential benefits of postoperative oral corticosteroids on surgical outcomes in CRSwNP patients and investigated the differential effects on eosinophilic CRSwNP (ECRSwNP) and noneosinophilic CRSwNP (NECRSwNP).

Causes of higher symptomatic airway load in patients with chronic rhinosinusitis

Background

Chronic rhinosinusitis display a variety of different phenotypes. The symptoms of disease are characterised by various signs and symptoms such as nasal congestion, nasal discharge, pressure sensation in the face and reduced or complete loss of smell.In a patient population undergoing functional endoscopic sinonasal surgery (FESS) for chronic rhinosinusitis, we wanted to investigate the clinical features and explore if the presence of biofilm, nasal polyps or other disease characteristic could serve as predictor for the symptomatic load. A patient group undergoing septoplasty without disease of the sinuses was included as control.

Methods

The Sinonasal outcome test (SNOT-20), EPOS visual analogue scale (VAS) and the Lund-Mackey CT score (LM CT score) were used to examine 23 patients with chronic rhinosinusitis without nasal polyps (CRSsNP), 30 patient with nasal polyps (CRSwNP) and 22 patients with septal deviation. Tissue samples were collected prospectively during surgery. The cohort has previously been examined for the presence of biofilm.

Results

Patients with CRSsNP and CRSwNP had significantly higher degree of symptoms compared to the septoplasty group (SNOT-20 scores of 39.8, 43.6 and 29.9, respectively, p?=?0.034). There were no significant differences in the total SNOT-20 or VAS symptoms scores between the CRSsNP and CRSwNP subgroups. However patients with nasal polyps showed significantly higher scores of symptoms related to sinonasal discomfort such as cough, runny nose and need to blow nose (p?=?0.011, p?=?0.046, p?=?0.001 respectively). Patients with nasal polyps showed a significantly higher LM CT score compared to patients without polyps (12.06 versus 8.00, p?=?0.001). The presence of biofilm did not impact the degree of symptoms.

Conclusion

The presence of nasal polyp formations in CRS patients was associated with a higher symptomatic airway load as compared to patients without polyps. These findings suggest that nasal polyps could be an indicator of more substantial sinonasal disease. The presence of biofilm did not impact the degree of symptoms, however, as biofilm seem to be a common feature of chronic rhinosinusitis (89% in this cohort), it is more likely to be involved in the development of the CRS, rather than being a surrogate marker for increased symptomatic load.

Auto-obliteration of maxillary sinuses through osteoneogenesis in children with cystic fibrosis: A possible new way to reduce morbidity

Background

Cystic Fibrosis is an autosomal recessive disorder with a mutation in the cystic fibrosis transmembrane regulator gene, leading to dysregulation of epithelial fluid transport, dehydration of airway surfaces and impaired mucociliary function in the sinuses, lungs, pancreas and other organs. This leads to thickened secretion which blocks the sinus ostia and promotes chronic bacterial overgrowth and destruction of the mucosa. Chronic rhinosinusitis in cystic fibrosis patients leads to a decreased quality of life involving increased hospitalizations, infections, pneumonia, and acute exacerbations, warranting multiple sinus surgeries. This study investigates the effects of a more aggressive surgical approach on reducing the need for repeat surgeries.

The impact of nasal airflow on sinus mucosa: A radiographic review

Background

Chronic rhinosinusitis (CRS) is a disease of widespread prevalence and high morbidity. Many suggest that the introduction of toxins and allergens via nasal airflow plays a significant role in the development of CRS. In patients who have undergone total laryngectomy, nasal airflow is disrupted, providing an opportunity to examine the role of nasal airflow in sinonasal pathology.

Quadrupedal head position enhances recovery from chronic maxillary sinusitis

Objectives

The position of human maxillary ostia is high on their superomedial walls, which may be suboptimal for natural drainage. Human maxillary sinuses exhibit better passive drainage through their ostia when tilted anteriorly to mimic a quadrupedal head position. We all know that sufficient drainage is very important for the treatment of chronic rhinosinusitis (CRS). Chronic maxillary sinusitis (CMS) is the high incidence of CRS. The aim of this study was to investigate the efficacy of quadrupedal head position in patients with CMS.

Methods

One hundred six patients diagnosed with CMS were enrolled. Patients were randomized to quadrupedal head position group and non-quadrupedal head position group for 6 weeks of treatment. Treatment outcomes were measured using 1) Lund-Mackay scoring system of pre-and post-treatment computer tomography (CT); and 2) Sinonasal Quality-of-Life (QoL) Survey completed at baseline and 6 weeks of therapy.

Results

There were statistically significant differences in QoL scores and CT scores between quadrupedal head position group and non-quadrupedal head position group. The quadrupedal head position group had much more improvements in QoL scores and CT scores than that of non-quadrupedal head position group. One patient in the quadrupedal head position group required functional endoscopic sinus surgery (ESS) due to persistent symptoms, and nine patients in non-quadrupedal head position group needed ESS. There were less patients that required ESS in the quadrupedal head position group than in the non-quadrupedal head position group.

Conclusions

The improvements of QoL scores and CT scores were significantly better in the quadrupedal head position group than that in the non-quadrupedal head position group. Quadrupedal head position can be valuable adjuvant therapy for patients with CMS.

Prospective evaluation of clarithromycin in recurrent chronic rhinosinusitis with nasal polyps

IntroductionThe antiinflammatory effects of macrolides, especially clarithromycin, have been described in patients with chronic rhinosinusitis without polyps and also other chronic inflammatory airway diseases. There is no consensus in the literature regarding the effectiveness of clarithromycin in patients with chronic rhinosinusitis with sinonasal polyposis and the national literature does not report any prospective studies on the efficacy of clarithromycin in chronic rhinosinusitis in our population.ObjectiveTo evaluate the effect of clarithromycin in the adjunctive treatment of recurrent chronic rhinosinusitis with sinonasal polyposis refractory to clinical and surgical treatment.MethodsOpen prospective study with 52 patients with chronic rhinosinusitis and recurrent sinonasal polyposis. All subjects received nasal lavage with 20 mL 0.9% SS and fluticasone nasal spray, 200 mcg / day, 12/12 h for 12 weeks; and clarithromycin 250 mg 8/8 h for 2 weeks and, thereafter, 12/12 h for 10 weeks. The patients were assessed by SNOT 20, NOSE and Lund-Kennedy scales before, immediately after treatment and 12 weeks after treatment. The patients were also evaluated before treatment with paranasal cavity computed tomography (Lund-Mackay) and serum IgG, IgM, IgA, IgE and eosinophil levels. The outcomes evaluated were: SNOT-20, NOSE and Lund-Kennedy.ResultsMost patients were women, aged 47 (15) years (median / interquartile range), and 61.5% (32/52) had asthma. All patients completed the follow-up after 12 weeks and 42.3% (22/52) after 24 weeks. Treatment resulted in a quantitative decrease in the SNOT-20 [2.3 (1.6) vs. 1.4 (1.6); Δ = ?0.9 (1.1); p < 0.01]; NOSE [65 (64) vs. 20 (63); Δ = ?28 (38), p < 0.01] and Lund-Kennedy [11 (05) vs. 07 (05); Δ = ?2 (05); p < 0.01] scores. SNOT-20 showed a qualitative improvement (>0.8) in 54% (28/52, p < 0.04) of patients, a group that showed lower IgE level [108 (147) vs. 289 (355), p < 0.01]. The group of patients who completed follow-up 12 weeks after the end of treatment (n = 22) showed no worsening of outcomes.ConclusionLong-term adjuvant use of low-dose clarithromycin for chronic rhinosinusitis patients with recurrent sinonasal polyposis refractory to clinical and surgical treatment has resulted in improved quality of life and nasal endoscopy findings, especially in patients with normal IgE levels. This improvement persisted in the patient group evaluated 12 weeks after the end of the treatment.

Entwicklung einer Bewertungsskala für den Sino-Nasal Outcome Test-20 German Adapted Version (SNOT-20 GAV)

Introduction

Quality of life measurements with the Sino-Nasal Outcome Test-20 German Adapted Version (SNOT-20 GAV) in chronic rhinosinusitis (CRS) patients require normative values measured in a comparison group taken from the normal population. These will make it possible to reach conclusions on correlations between scores and severity of symptoms and also on how close such patients’ scores can get to those scores recorded in healthy subjects after surgical treatment.

Patients and methods

We collected SNOT-20 GAV data and data on the presence of CRS from 778 subjects via a web-based survey of employees of the University Hospital in Heidelberg. For comparison we used data collected before surgery and at 3 months and 1 year after surgery from 163 CRS patients who had undergone endonasal sinus surgery (ESS).

Results

Gender and age had no clinically significant impact on the SNOT-20 GAV scores. We defined an assessment scale with four classes of symptom intensity. Surgically treated patients with CRS showed a persisting small disadvantage in the scales of the SNOT-20 GAV compared with the reference subgroup without CRS. When surgically treated CRS patients were compared with the entire reference group these disadvantages were only obvious in the Primary Nasal Symptoms (PNS) scale and not in the other scales measuring quality of life.

Conclusion

Patients with CRS benefit from ESS and subsequently reach scores similar to those recorded in the reference group. The newly developed four-level assessment scale is easy to use and gives the attending physician additional information about the severity of the patients’ illness and its effects on their subjective wellbeing.

目的：探讨变态反应性因素对慢性鼻-鼻窦炎（CRS）内镜鼻窦手术（ESS）疗效的影响。方法：术前对115例患者进行变态反应性因素血清相关指标测定：血清总IgE浓度、血清特异性变应原IgE半定量检测、血清ECP浓度;进行症状与生活质量调查：VAS、SNOT-20、SF-36问卷调查;并进行LundMackayCT系统评分及海口标准分型分期。实际随访ESS术后1年以上患者74例,进行鼻内镜检查,根据术后疗效评定海口标准、Lund—Kennedy内镜评分系统进行评估;并进行VAS、SNOT-20、SF-36问卷调查。结果：血清总IgE浓度增高者术后VAS评分改善低于不增高者（P〈0．05）。术前海口分型Ⅱ、Ⅲ型患者中血清总IgE浓度增高者手术有效率、术后LundKennedy内镜评分较不增高者差（P〈0．05）。3种及3种以上血清特异性变应原IgE阳性患者的手术有效率、术后Lund—Kennedy内镜评分较3种以下阳性患者差（P〈0．05）。血清特异性变应原IgE强阳性患者的手术有效率、术后Lund—Kennedy内镜评分、术后VAS评分、术后SNOT-20评分较无强阳性患者差（P〈0．05）。ESS术后有效患者的血清ECP浓度显著低于无效患者（P〈0．05）。血清ECP浓度与LundKennedy内镜评分成正相关（r=0．49,P〈0．05）。术前海口分型Ⅱ、Ⅲ型患者中,血清ECP浓度增高的患者手术有效率、术后Lund—Kennedy内镜评分、术后VAS评分、术后VAS评分改善较血清ECP浓度不增高者差（P〈0．05）。结论：变态反应性因素对CRS患者主客观疗效有-定的负面影响作用。血清总IgE浓度增高与血清ECP浓度增高在伴鼻息肉的患者中提示手术疗效不佳。本研究为CRS的免疫治疗提供了-定依据。     

Surgical Management of Rhinosinusitis in Onco-Hematological Patients

Objectives

In onco-hematological diseases, the incidence of paranasal sinuses infection dramatically increase and requires a combination of medical and surgical therapy. Balloon dilatation surgery (DS) is a minimally invasive, tissue preserving procedure. The study evaluates the results of DS for rhinosinusitis in immunocompromised patients.

Methods

A retrospective chart review was conducted in 110 hematologic patients with rhinosinusitis. Twenty-five patients were treated with DS technique and 85 patients with endoscopic sinus surgery (ESS). We considered the type of anesthesia and the extent of intra- and postoperative bleeding. Patients underwent Sino-Nasal Outcome Test (SNOT-20) to evaluate changes in subjective symptoms and global patient assessment (GPA) questionnaire to value patient satisfaction.

Results

Local anesthesia was employed in 8 cases of DS and in 15 of ESS. In 50 ESS patients, an anterior nasal packing was placed and in 12 cases a repacking was necessary. In the DS group, nasal packing was required in 8 cases and in 2 cases a repacking was placed (P=0.019 and P=0.422, respectively). The SNOT-20 change score showed significant improvement of health status in both groups. However the DS group showed a major improvement in 3 voices: need to blow nose, runny nose, and facial pain/pressure. The 3-month follow-up GPA questionnaire showed an higher satisfaction of DS group.

Conclusion

Balloon DS represents a potentially low aggressive treatment and appears to be relatively safe and effective in onco-hematologic patients. All these remarks may lead the surgeon to consider a larger number of candidates for surgical procedure.
