Abstract
Background: Inhalation of hypertonic saline (HS) is standard of care in patients with cystic fibrosis (CF). However, it is unclear if adding salbutamol has-besides bronchodilation-further benefits, for example, on the mucociliary clearance. We assessed this in vitro by measuring the ciliary beating frequency (CBF) and the mucociliary transport rate (MCT) in nasal epithelial cells (NECs) of healthy volunteers and patients with CF. Aims: To investigate the effect of HS, salbutamol, and its combination on (muco)ciliary activity of NECs in vitro, and to assess potential differences between healthy controls and patients with CF. Methods: NECs obtained from 10 healthy volunteers and 5 patients with CF were differentiated at the air-liquid interface and aerosolized with 0.9% isotonic saline ([IS] control), 6% HS, 0.06% salbutamol, or combined HS and salbutamol. CBF and MCT were monitored over 48-72 hours. Results: In NECs of healthy controls, the absolute CBF increase was comparable for all substances, but CBF dynamics were different: HS increased CBF slowly and its effect lasted for an extended period, salbutamol and IS increased CBF rapidly and the effect subsided similarly fast, and HS and salbutamol resulted in a rapid and long-lasting CBF increase. Results for CF cells were comparable, but less pronounced. Similar to CBF, MCT increased after the application of all the tested substances. Conclusion: CBF and MCT of NECs of healthy participants and CBF of patients with CF increased upon treatment with aerosolized IS, HS, salbutamol, or HS and salbutamol, showing a relevant effect for all tested substances. The difference in the CBF dynamics can be explained by the fact that the properties of the mucus are changed differently by different saline concentrations.

J Inflamm Res 2022; 15:3983-3995. [PMID: 35873384 PMCID: PMC9296884 DOI: 10.2147/jir.s365611] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/09/2022] [Accepted: 07/10/2022] [Indexed: 11/25/2022] Open
Abstract
Purpose Chronic rhinitis (CR) is a common chronic inflammation of the nasal mucosa. Nasal saline irrigation has been demonstrated to be an effective treatment for CR. In this study, we investigated the beneficial effects of hydrogen-rich saline irrigation as an anti-inflammatory irrigation therapy for CR and compared its effectiveness over saline irrigation. Hydrogen-rich saline (HRS) was investigated due to its antioxidant and anti-inflammatory properties. Methods A total of 120 patients with CR were randomly divided into two groups, patients irrigated with HR (HRS group) and the control group irrigated with saline (NS group). A randomized, double-blind control study was performed. The main observation index in this study was the total score of nasal symptoms (TNSS). In addition, eosinophilic protein (ECP) of the nasal secretions, nasal nitric oxide (nNO) levels, and levels of regulatory T cells (Treg) and regulatory B cells (Breg) were also compared between the two groups. Furthermore, patients with allergic rhinitis (AR) and non-allergic rhinitis (NAR) were also evaluated based on serum-specific IgE positivity. Results After treatment, TNSS and nasal ECP in the two groups decreased significantly (P<0.05), with patients in the HRS group showing significantly lower levels compared to the NS group (P<0.05). There were no significant differences in Treg and Breg levels between the two groups. Subgroup analysis showed that TNSS in the AR-HRS group showed a more significant reduction compared to the AR-NS group (P<0.05); however, there were no significant differences for the other inflammatory biomarkers (P>0.05). ECP levels were reduced significantly in the NAR subgroup compared to NS irrigation (P<0.05). There were no obvious adverse events observed in patients during the entire treatment period. Conclusion Compared to saline irrigation, HRS nasal irrigation was found to improve CR clinical symptoms, especially in patients with AR. HRS could effectively be used for the clinical treatment of patients with CR. ![]()

Abstract
The history of saline nasal irrigation (SNI) is indeed a long one, beginning from the ancient Ayurvedic practices and gaining a foothold in the west at the beginning of the 20th century. Today, there is a growing number of papers covering the effects of SNI, from in vitro studies to randomized clinical trials and literature overviews. Based on the recommendations of most of the European and American professional associations, seawater, alone or in combination with other preparations, has its place in the treatment of numerous conditions of the upper respiratory tract (URT), primarily chronic (rhino)sinusitis, allergic rhinitis, acute URT infections and postoperative recovery. Additionally, taking into account its multiple mechanisms of action and mounting evidence from recent studies, locally applied seawater preparations may have an important role in the prevention of viral and bacterial infections of the URT. In this review we discuss results published in the past years focusing on seawater preparations and their use in clinical and everyday conditions, since such products provide the benefits of additional ions vs. saline, have an excellent safety profile and are recommended by most professional associations in the field of otorhinolaryngology.

Abstract
BACKGROUND Pharmacological treatment for bronchiolitis is primarily supportive because bronchodilators, steroids, and antibiotics, show little benefit. Clinical studies have suggested that nebulized 3% hypertonic solution is useful for infants with bronchiolitis. This study aims to evaluate the cost-effectiveness of the HS inhalations in infant bronchiolitis in a tropical country. METHODS Decision tree analysis was used to calculate the expected costs and QALYs. All cost and use of resources were collected directly from medical invoices of 193 patient hospitalized with diagnosis of bronchiolitis in tertiary centers, of Rionegro, Colombia. The utility values applied to QALYs calculations were collected from the literature. The economic analysis was carried out from a societal perspective. RESULTS The model showed that nebulized 3% hypertonic solution, was associated with lower total cost than controls (US $200vs US $240 average cost per patient), and higher QALYs (0.92 vs 0.91 average per patient); showing dominance. A position of dominance negates the need to calculate an incremental cost-effectiveness ratio. CONCLUSION The nebulized 3% hypertonic solution was cost-effective in the inpatient treatment of infant bronchiolitis. Our study provides evidence that should be used by decision-makers to improve clinical practice guidelines and should be replicated to validate their results in other tropical countries.

Abstract
Nebulization with saline solution, although commonly used to alleviate respiratory symptoms, particularly in children, is often questioned concerning its effectiveness. In this study, we investigated the effects of isotonic saline nebulization on lung function in 40 children (mean age of 14±1 years) suffering from different types of airway disorders. Measurements were carried out directly before and up to 15 min after nebulization, for six days in a row, always on the same day time in the morning. The children were divided into two study groups according to the baseline ratio of forced expired volume in one second/forced vital capacity (FEV1/FVC), below and above 80 %. We found significant improvements after saline nebulization in FEV1, mid-expiratory flow at 50 % and 75 % of FVC (MEF50 and MEF75), and peak expiratory flow (PEF) in the group with the baseline FEV1/FVC less than 80 %. In contradistinction, children with an index greater than 80 % displayed no appreciable changes in the lung function variables when compared with the baseline level before saline nebulization. We conclude that isotonic saline nebulization might mitigate the functional signs of threatening pulmonary obstruction and as such may be clinically useful in pediatric patients with mild respiratory problems.

Abstract
BACKGROUND Nasal congestion represents a troublesome health issue which is especially and invalidating in children. Effective nasal drugs, such as sympathomimetic drugs, are usually forbidden in children under 12 years of age because of their potential systemic adverse effects. Hypertonic nasal physiological solutions have recently been successfully used to decongest nasal mucosa in children: its mechanical activity has been universally recognized as safe and effective and it represents a well-established, useful treatment in children. METHODS We have retrospectively analyzed a case series of 40 children treated for 4 days (96 hours) with a new class 1s medical device nasal hypertonic spray containing Pirometaxine™ (Narlisim™) in outpatient affected by nasal congestion due to common cold. Every child was evaluated on a 3-point symptom assessment scale (0: no symptom; 1: mild symptom; 2: moderate symptom; 3: severe symptom) at the beginning of the trial (T0) and after 48 (T1) and 96 hours (T2). The symptoms assessed were nasal obstruction, nasal secretion, headache, flash of cold, pharyngodynia, cough, and sneeze. RESULTS The results, in terms of short-term efficacy to control nasal obstruction (T1 vs. T0: P<0.0001; T2 vs. T0: P<0.0001), nasal secretion (T1 vs. T0: P<0.0001; T2 vs. T0: P<0.0001) and all the symptoms related to common cold have supported the efficacy of this hypertonic nasal solution. No adverse events have been pointed out during the trial supporting the safety of this new nasal hypertonic approach. CONCLUSIONS The absence of adverse events after 48-96 hours along with the short-term effectiveness of this new treatment seems to represent a new, safe option to treat children affected by nasal congestion secondary to common cold. Considering the current lack of safe treatments for children under 12 years of age, Narlisim™ can be considered as a useful short-term option to control nasal congestion in children.

Abstract
A meta-analysis was performed to analyze the efficacy of 3% hypertonic saline (HS) in bronchiolitis. Pubmed and MEDLINE databases were searched for relevant articles. A total of 2 authors selected the articles according to the inclusion criteria and then data were carefully extracted. Weighted mean difference (WMD) with 95% confidence interval (95% CI) values were used to pool continuous data, including length of stay and clinical severity score (CSS). Relative risk (RR) with 95% CI was calculated to determine the association between 3% HS and re-admission. The pooled data revealed that infants treated with 3% HS exhibited shorter durations of hospitalization compared with those treated with normal saline (NS; WMD=-0.43; 95% CI=-0.70, -0.15). Subgroup analysis examining the combination of HS or NS with additional medication demonstrated that 3% HS with epinephrine significantly decreased the length of hospital stay, with a WMD=-0.62 (95% CI=-0.90, -0.33). The results indicated a lower CSS score in the 3% HS group compared with the NS group (SMD=-0.80; 95% CI=-1.06, -0.54). The pooled outcome indicated a beneficial effect of 3% HS on decreasing re-admission rates compared with NS (RR=0.93; 95% CI=0.70, 1.23). No potential publication bias was observed (Begg's, P=0.133; Egger's, P=0.576). In conclusion, 3% HS was demonstrated to be a more successful therapy compared with NS for infants with bronchiolitis.

Abstract
Background Saline fluid nebulization is highly recommend to combat the complications following tracheostomy, yet the understandings on the role of osmolality in saline solution for nebulization remain unclear. Objectives To investigate the biological changes in the early stage after tracheostomy, to verify the efficacy of saline fluid nebulization and explore the potential role of osmolality of saline nebulization after tracheostomy. Methods Sprague-Dawley rats undergone tracheostomy were taken for study model, the sputum viscosity was detected by rotational viscometer, the expressions of TNF-α, AQP4 in bronchoalveolar lavage fluid were assessed by western blot analysis, and the histological changes in endothelium were evaluated by HE staining and scanning electron microscopy (SEM). Results Study results revealed that tracheostomy gave rise to the increase of sputum viscosity, TNF-α and AQP4 expression, mucosa and cilia damage, yet the saline fluid nebulization could significantly decrease the changes of those indicators, besides, the hypertonic, isotonic and hypertonic saline nebulization produced different efficacy. Conclusions Osmolality plays an important role in the saline fluid nebulization after tracheostomy, and 3% saline fluid nebulization seems to be more beneficial, further studies on the role of osmolality in saline fluid nebulization are warranted.

Abstract
BACKGROUND Cilia in the human respiratory tract play a critical role in clearing mucus and debris from the airways. Their function can be affected by a number of drugs or other substances, many of which alter ciliary beat frequency (CBF). This has implications for diseases of the respiratory tract and nasal drug delivery. This article is a systematic review of the literature that examines 229 substances and their effect on CBF. METHODS MEDLINE was the primary database used for data collection. Eligibility criteria based on experimental design were established, and 152 studies were ultimately selected. Each individual trial for the substances tested was noted whenever possible, including concentration, time course, specific effect on CBF, and source of tissue. RESULTS There was a high degree of heterogeneity between the various experiments examined in this article. Substances and their general effects (increase, no effect, decrease) were grouped into six categories: antimicrobials and antivirals, pharmacologics, human biological products, organisms and toxins, drug excipients, and natural compounds/other manipulations. CONCLUSION Organisms, toxins, and drug excipients tend to show a cilioinhibitory effect, whereas substances in all other categories had mixed effects. All studies examined were in vitro experiments, and application of the results in vivo is confounded by several factors. The data presented in this article should be useful in future respiratory research and examination of compounds for therapeutic and drug delivery purposes.

Abstract
OBJECTIVE This update of a 2007 guideline from the American Academy of Otolaryngology--Head and Neck Surgery Foundation provides evidence-based recommendations to manage adult rhinosinusitis, defined as symptomatic inflammation of the paranasal sinuses and nasal cavity. Changes from the prior guideline include a consumer added to the update group, evidence from 42 new systematic reviews, enhanced information on patient education and counseling, a new algorithm to clarify action statement relationships, expanded opportunities for watchful waiting (without antibiotic therapy) as initial therapy of acute bacterial rhinosinusitis (ABRS), and 3 new recommendations for managing chronic rhinosinusitis (CRS). PURPOSE The purpose of this multidisciplinary guideline is to identify quality improvement opportunities in managing adult rhinosinusitis and to create explicit and actionable recommendations to implement these opportunities in clinical practice. Specifically, the goals are to improve diagnostic accuracy for adult rhinosinusitis, promote appropriate use of ancillary tests to confirm diagnosis and guide management, and promote judicious use of systemic and topical therapy, which includes radiography, nasal endoscopy, computed tomography, and testing for allergy and immune function. Emphasis was also placed on identifying multiple chronic conditions that would modify management of rhinosinusitis, including asthma, cystic fibrosis, immunocompromised state, and ciliary dyskinesia. ACTION STATEMENTS The update group made strong recommendations that clinicians (1) should distinguish presumed ABRS from acute rhinosinusitis (ARS) caused by viral upper respiratory infections and noninfectious conditions and (2) should confirm a clinical diagnosis of CRS with objective documentation of sinonasal inflammation, which may be accomplished using anterior rhinoscopy, nasal endoscopy, or computed tomography. The update group made recommendations that clinicians (1) should either offer watchful waiting (without antibiotics) or prescribe initial antibiotic therapy for adults with uncomplicated ABRS; (2) should prescribe amoxicillin with or without clavulanate as first-line therapy for 5 to 10 days (if a decision is made to treat ABRS with an antibiotic); (3) should reassess the patient to confirm ABRS, exclude other causes of illness, and detect complications if the patient worsens or fails to improve with the initial management option by 7 days after diagnosis or worsens during the initial management; (4) should distinguish CRS and recurrent ARS from isolated episodes of ABRS and other causes of sinonasal symptoms; (5) should assess the patient with CRS or recurrent ARS for multiple chronic conditions that would modify management, such as asthma, cystic fibrosis, immunocompromised state, and ciliary dyskinesia; (6) should confirm the presence or absence of nasal polyps in a patient with CRS; and (7) should recommend saline nasal irrigation, topical intranasal corticosteroids, or both for symptom relief of CRS. The update group stated as options that clinicians may (1) recommend analgesics, topical intranasal steroids, and/or nasal saline irrigation for symptomatic relief of viral rhinosinusitis; (2) recommend analgesics, topical intranasal steroids, and/or nasal saline irrigation) for symptomatic relief of ABRS; and (3) obtain testing for allergy and immune function in evaluating a patient with CRS or recurrent ARS. The update group made recommendations that clinicians (1) should not obtain radiographic imaging for patients who meet diagnostic criteria for ARS, unless a complication or alternative diagnosis is suspected, and (2) should not prescribe topical or systemic antifungal therapy for patients with CRS.

Abstract
BACKGROUND Nasya/Prevalin is a natural, drug-free nasal spray for treatment and prevention of allergic rhinitis. Because of its thixotropic property, it forms a barrier on the nasal mucosa, preventing allergen contact. This study assesses the clinical efficacy and safety of Nasya/Prevalin in a nasal provocation test with house dust mite allergens. METHODOLOGY/PRINCIPAL In this randomised, double-blind, placebo-controlled trial, 20 subjects suffering from allergic rhinitis because of house dust mite allergens received a single dose of Nasya/Prevalin or saline spray before allergen challenge. Total nasal symptom score and total ocular symptom score were assessed 15, 30, 60, 75, 90, 120 and 240 min after challenge. Further, the appearance of the mucosa was examined by rhinoscopy. RESULTS A single treatment with Nasya/Prevalin led to a significant reduction of TNSS at 60, 75 and 90 min after dust mite allergen challenge as compared with placebo (pVCAS = 0.021, pVCAS = 0.035, pVCAS = 0.036, respectively). Mucosa changes assessed by the rhinoscopic score (on swelling, secretion and colour) were significantly worse in the placebo group compared with the Nasya/Prevalin group (P = 0.033). Nasya/Prevalin was well tolerated, and the safety was comparable with placebo. CONCLUSIONS Treatment with Nasya/Prevalin was effective in preventing allergic reactions induced by dust mite allergen challenge.

Abstract
Chronic rhinosinusitis is a multifactorial disorder that may be heterogeneous in presentation and clinical course. While the introduction of endoscopic sinus surgery revolutionized surgical management and has led to significantly improved patient outcomes, medical therapy remains the foundation of long-term care of chronic rhinosinusitis, particularly in surgically recalcitrant cases. A variety of devices and pharmaceutical agents have been developed to apply topical medical therapy to the sinuses, taking advantage of the access provided by endoscopic surgery. The goal of topical therapy is to address the inflammation, infection, and mucociliary dysfunction that underlies the disease. Major factors that impact success include the patient's sinus anatomy and the dynamics of the delivery device. Despite a growing number of topical treatment options, the evidence-based literature to support their use is limited. In this article, we comprehensively review current delivery methods and the available topical agents. We also discuss biotechnological advances that promise enhanced delivery in the future, and evolving pharmacotherapeutical compounds that may be added to rhinologist's armamentarium. A complete understand of topical drug delivery is increasingly essential to the management of chronic rhinosinusitis when traditional forms of medical therapy and surgery have failed.

Abstract
OBJECTIVE This review examines the literature regarding nasal saline irrigation in the management of sinonasal disease. We explore the various properties of nasal irrigation solutions and their effects on nasal symptoms. DATA SOURCES English-language studies identified from MEDLINE and the Cochrane Central Register of Controlled Trials through December 2011. STUDY SELECTIONS Randomized, controlled trials (RCTs), prospective controlled and comparative studies, and observational studies reporting on the indications, efficacy, and safety of nasal saline irrigation. RESULTS Nasal saline irrigation has often been used as both a solo and an adjunctive treatment in sinonasal diseases, including allergic rhinitis and chronic rhinosinusitis. Nasal saline irrigation has contributed to a reduction of inflammation as well as relief of nasal symptoms. Identifying the optimal technique is hampered by the fact that studies have employed various delivery devices and saline compositions, which subsequently have demonstrated different effects on mucus clearance, ciliary beat activity, and inflammatory mediators. CONCLUSION Overall, the data appear to demonstrate some small clinical benefit to nasal saline irrigation. Nasal saline irrigation is well tolerated, with minimal side effects. Further definitive studies are needed to optimize efficacy.

Abstract
Rhinosinusitis (RS) affects approximately 1 in 7 adults in the United States, and its effect on quality of life, productivity, and finances is substantial. During the past 10 years, several expert panels from authoritative bodies have published evidence-based guidelines for the diagnosis and management of RS and its subtypes, including acute viral RS, acute bacterial RS, chronic RS (CRS) without nasal polyposis, CRS with nasal polyposis, and allergic fungal RS. This review examines and compares the recommendations of the Rhinosinusitis Initiative, the Joint Task Force on Practice Parameters, the Clinical Practice Guideline: Adult Sinusitis, the European Position Paper on Rhinosinusitis and Nasal Polyps 2007, and the British Society for Allergy and Clinical Immunology. Points of consensus and divergent opinions expressed in these guidelines regarding classification, diagnosis, and management of adults with acute RS (ARS) and CRS and their various subtypes are highlighted for the practicing clinician. Key points of agreement regarding therapy in the guidelines for ARS include the efficacy of symptomatic treatment, such as intranasal corticosteroids, and the importance of reducing the unnecessary use of antibiotics in ARS; however, guidelines do not agree precisely regarding when antibiotics should be considered as a reasonable treatment strategy. Although the guidelines diverge markedly on the management of CRS, the diagnostic utility of nasal airway examination is acknowledged by all. Important and relevant data from MEDLINE-indexed articles published since the most recent guidelines were issued are also considered, and needs for future research are discussed.

Foreman A, Wormald PJ. Can bottle design prevent bacterial contamination of nasal irrigation devices? Int Forum Allergy Rhinol 2011; 1:303-7.

Abstract
BACKGROUND Saline nasal irrigation is a mainstay in the medical management of chronic rhinosinusitis (CRS) with proven efficacy. However, bacterial contamination of irrigation bottles has recently been reported and this may contribute to recurrent infections. Sterilization is effective but could a change in bottle design obviate the need for regular sterilization? METHODS A total of 20 stable CRS patients were given a NasalCare® (Techworld Corporation, Inc., Downington, PA) irrigation bottle to use regularly for 1 week. This bottle incorporates a 1-way valve to prevent irrigant regurgitation. Swabs were taken from their sinonasal cavity and 3 sites on the bottle-nozzle, valve, and inner surface. RESULTS This study cultured a range of organisms from all sites of the bottle, including common CRS pathogens such as S. aureus, P. aeruginosa, and E. coli. Whereas the bottle's inner surface had the lowest bacterial recovery rate, the frequent culture of organisms at this site suggests a 1-way valve cannot completely prevent irrigant reflux. The high rate of organism detection at the nozzle and valve of the bottle is concerning, as bacteria at these sites may be transported to the nose during nasal douching. CONCLUSION Saline irrigation will continue to be an essential component of CRS management. However, despite employing a 1-way liquid valve in this study, nasal irrigation bottles can still become contaminated with bacteria. Thus, patient education, irrespective of bottle design, will be essential in preventing bacterial contamination of nasal irrigation devices. The results of our survey suggest this message is not getting across to our patients.

Abstract
Background Chronic rhinosinusitis that is refractory to medical or surgical intervention may involve a particularly resistant form of infection known as a bacterial biofilm that is recalcitrant to antibiotics secondary to physical barrier characteristics. Recently, a novel sinus cleansing solution, citric acid/zwitterionic surfactant (CAZS) was shown to be extremely effective in disrupting biofilms in vitro. The purpose of this study was to determine the effects of CAZS on sinonasal epithelium in vivo compared with normal saline. Methods Indwelling catheters were placed into the right maxillary sinus of New Zealand white rabbits. CAZS solution or normal saline (10 mL) was instilled at a rate of 20 mL/minute into the sinus followed by aspiration. Rabbits were killed 1, 3, and 6 days after treatment. Mucosa from both maxillary sinuses was harvested and evaluated for physiological activity (ciliary beating) as well as morphological integrity of the epithelium by scanning electron microscopy. Results One day after treatment, beating cilia was evident with morphological analysis shown intact epithelium with 80–85% denudation of cilia compared with saline. Three days after treatment, ciliary activity was again noted with morphological evidence of persistent denuded cilia. By day 6 after treatment, the epithelium had regenerated cilia over the apical surface. Throughout the recovery period beating cilia was evident in CAZS-treated sinuses. Conclusion This study shows that although CAZS acutely denudes respiratory cilia, the remaining cilia are active. Additionally, the epithelial barrier appears intact with active ciliogenesis, and reciliation of the mucosal surface occurring 6 days after treatment.

Abstract
BACKGROUND Postoperative irrigation after endoscopic sinus surgery and endoscopic modified Lothrop procedure is used to remove nasal crusts and to improve wound healing. To evaluate the optimal application protocol for irrigation of the frontal sinus, a prospective cadaver study was performed. METHODS An endoscopic modified Lothrop procedure and complete sphenoethmoidectomy were performed in 19 heads. Each was irrigated with a 1.5% solution of water and different colors using nasal spray and a squeeze bottle filled with 50, 100, and 200 mL. Intensity of local staining and percentage of area were documented using standardized videoendoscopy after irrigation in "bending over the sink" or "vertex to floor" position. Grading was performed by two independent observers for 23 anatomic regions, including the stained circumference of maxillary and frontal ostia. To evaluate the influence of the anatomy, acoustic rhinometry was performed. ANOVA was used to evaluate effects of application methods and head positions using GenStat 8.2 (Lawes Agricultural Trust, Rothamsted Experimental Station, Harpenden, U.K.) using an appropriate block structure. RESULTS With regard to the frontal sinus, we were able to show clear superiority of the squeeze bottle technique filled with 200 mL and applied in the "vertex to floor position." CONCLUSION In a relatively fit and flexible patient the vertex to floor position using a squeeze bottle technique is advocated. There may be some patients, however, for whom this position is not feasible. In these patients "bending over the sink," while inferior to the "vertex to floor" position, still ensures some irrigation of the frontal sinus.

Abstract
BACKGROUND The purpose of this study was to determine if bulb syringe irrigators are a potential source for bacterial contamination in patients with chronic rhinosinusitis. METHODS Standard 3-oz bulb syringe irrigators (n = 24) were each flushed with the following solutions twice daily: A (n = 8), sterile isotonic saline; B (n = 8), prepared hypertonic saline (3 tsp table salt/L of sterile water); and C (n = 8), prepared baking soda/saline (1 tsp table salt + 1 tsp baking soda/L of commercial sterile water). Syringes were stored on a residential bathroom counter, and two from each group were harvested for culture weekly for 4 weeks. RESULTS There was no growth from syringes irrigated with any of the three solutions after the first 7 days of irrigation. After the entire 4-week study period, potential pathogens were recovered from 6/8 (75%) bulbs from group A, 0/8 bulbs from group B, and 1/8 bulbs (12.5%) from group C. All positive cultures revealed growth by 1-2 days postinoculation (p = 0.002). The organism recovered from syringes in group A was Pseudomonas fluorescens in all six specimens. The one positive culture in group C represented a single colony of Gram-positive cocci. CONCLUSION Under realistic conditions, bulb syringes are susceptible to contamination with potential bacterial pathogens, particularly when using unbuffered isotonic saline.

Abstract
INTRODUCTION Postoperative bleeding and adhesion formation remain the two major problems after endoscopic sinus surgery (ESS). This study investigates the effect on adhesion formation and wound healing in a sheep model of chronic sinusitis of three topical agents: recombinant tissue factor (rTF, Dade Innovin, Marburg, Germany), poly-ethylene glycol (SprayGel, Confluent Surgical, Waltham, MA), and a novel chitosan-dextran derivative gel (CD, Department of Chemistry, University of Otago, Dunedin, New Zealand). METHODS Twenty sheep with chronic sinusitis underwent ESS with standardized mucosal injuries created on the lateral nasal wall and the ethmoid region. Injured areas were divided into four groups, and one of the three agents or control (no treatment) was randomly applied. The presence and severity of adhesions were noted and the healing was evaluated by taking brushings for ciliary beat frequency and biopsies of the injured regions at day 28, 56, 84, and 112 post initial surgery. The biopsy specimens were assessed for re-epithelialisation using light microscopy and scanning electron microscopy for reciliation. The cytobrush specimens assessed cilial function by measuring ciliary beat frequency. RESULTS CD significantly decreased lateral nasal wall and ethmoidal adhesions compared to tissue factor at all time points (5% vs. 25%, and 0 vs. 50%, respectively). There was a noticeable trend toward decreased adhesions on the lateral nasal wall and ethmoids in the SprayGel group (10% and 14%) and the CD group (10% and 0%) compared to controls (15% and 40%). The CD group had a significantly greater percentage of re-epithelialisation at day 28 and day 84 compared to the rTF group (70% vs. 33%, P < .001; 84.5% vs. 61%, P < 0.05). At day 28, the CD group was significantly more ciliated than control (62% vs. 31%, P < .01) and than rTF (62% vs. 23%, P < .001). This difference between CD and rTF reciliation remained significant at day 56 (67% vs. 40%, P < .05). In addition, the mean cilial grade for CD at day 112 was significantly better than control (1.9 vs. 2.7, P < .05). CONCLUSION In the sheep model of chronic sinusitis, CD significantly improves microscopic wound healing and reduces adhesion formation after ESS.

Abstract
BACKGROUND In alternative and complementary medicine, the use of essential and fatty oils has become more and more popular. In addition to conventional medical therapies, self-medication is showing increasing popularity, using agents with unclear compounds and poorly controlled dosages. Among other disorders, these alternative treatments are used in bronchitis and rhinitis, including some topical applications. Thus, the influence on ciliated epithelia should be evaluated, because a disturbance of the ciliary function can lead to recurrent sinusitis and chronic rhinosinusitis. The aim of this study was to test the influence of fatty and essential oils on the ciliary beat frequency (CBF) of nasal mucosa in vivo. METHODS The influence of sesame oil, soy oil, peanut oil, Miglyol 840, thyme oil, lavender oil, eucalyptus oil, and menthol on the ciliary activity of nasal brushings was evaluated by digital high-speed imaging. RESULTS The presence of most fatty oils resulted in an increase in CBF, the effect being highest for peanut oil. Miglyol 840 had no significant influence on CBF. The essential oils were tested at a concentration of 0.2 and 2%. Thyme oil did not affect CBF, whereas the presence of all other essentials oils resulted in an increase in CBF; the effect was higher at 0.2% than at 2%. CONCLUSION Except thyme oil and Miglyol 840, all tested oils caused an increase in CBF. Interestingly, the 0.2% concentrations of essential oils resulted in stronger effects when compared with the 2% concentrations.

Abstract
OBJECTIVES A variety of topical preparations are used for symptomatic relief following nasal surgery. The aim of this study was to compare the effect of two commonly used products on patient symptom scores following nasal surgery. DESIGN Randomised, single-blinded, comparative clinical trial. SETTING A single, secondary otorhinolaryngology centre. PARTICIPANTS One hundred and twenty patients undergoing septoplasty or functional endoscopic sinus surgery as an isolated procedure between November 2003 and January 2006. Patients undergoing additional nasal procedures were excluded, as were those requiring additional post-operative medications other than standardised analgesia. METHODS Following nasal surgery, patients were randomised to receive either xylometazoline hydrochloride 0.1 per cent nasal spray or a sterile physiological saline aerosol. MAIN OUTCOME MEASURES Visual analogue scale symptom scores for nasal obstruction, rhinorrhoea, pain, loss of sense of smell and bleeding were assessed at day 10 post-operatively. RESULTS Post-operative symptom scores were compared between treatment groups. Overall, median pain scores were significantly higher in the xylometazoline group (p = 0.03, chi-square test). When analysed by procedure, median pain scores were significantly higher in septoplasty patients using xylometazoline (p = 0.019, chi-square test). CONCLUSION There is no evidence to support the use of xylometazoline hydrochloride 0.1 per cent nasal spray over aerosolised physiological saline alone, following nasal surgery. Furthermore, there may be more pain associated with the post-operative use of xylometazoline.

Abstract
OBJECTIVE This guideline provides evidence-based recommendations on managing sinusitis, defined as symptomatic inflammation of the paranasal sinuses. Sinusitis affects 1 in 7 adults in the United States, resulting in about 31 million individuals diagnosed each year. Since sinusitis almost always involves the nasal cavity, the term rhinosinusitis is preferred. The guideline target patient is aged 18 years or older with uncomplicated rhinosinusitis, evaluated in any setting in which an adult with rhinosinusitis would be identified, monitored, or managed. This guideline is intended for all clinicians who are likely to diagnose and manage adults with sinusitis. PURPOSE The primary purpose of this guideline is to improve diagnostic accuracy for adult rhinosinusitis, reduce inappropriate antibiotic use, reduce inappropriate use of radiographic imaging, and promote appropriate use of ancillary tests that include nasal endoscopy, computed tomography, and testing for allergy and immune function. In creating this guideline the American Academy of Otolaryngology-Head and Neck Surgery Foundation selected a panel representing the fields of allergy, emergency medicine, family medicine, health insurance, immunology, infectious disease, internal medicine, medical informatics, nursing, otolaryngology-head and neck surgery, pulmonology, and radiology. RESULTS The panel made strong recommendations that 1) clinicians should distinguish presumed acute bacterial rhinosinusitis (ABRS) from acute rhinosinusitis caused by viral upper respiratory infections and noninfectious conditions, and a clinician should diagnose ABRS when (a) symptoms or signs of acute rhinosinusitis are present 10 days or more beyond the onset of upper respiratory symptoms, or (b) symptoms or signs of acute rhinosinusitis worsen within 10 days after an initial improvement (double worsening), and 2) the management of ABRS should include an assessment of pain, with analgesic treatment based on the severity of pain. The panel made a recommendation against radiographic imaging for patients who meet diagnostic criteria for acute rhinosinusitis, unless a complication or alternative diagnosis is suspected. The panel made recommendations that 1) if a decision is made to treat ABRS with an antibiotic agent, the clinician should prescribe amoxicillin as first-line therapy for most adults, 2) if the patient worsens or fails to improve with the initial management option by 7 days, the clinician should reassess the patient to confirm ABRS, exclude other causes of illness, and detect complications, 3) clinicians should distinguish chronic rhinosinusitis (CRS) and recurrent acute rhinosinusitis from isolated episodes of ABRS and other causes of sinonasal symptoms, 4) clinicians should assess the patient with CRS or recurrent acute rhinosinusitis for factors that modify management, such as allergic rhinitis, cystic fibrosis, immunocompromised state, ciliary dyskinesia, and anatomic variation, 5) the clinician should corroborate a diagnosis and/or investigate for underlying causes of CRS and recurrent acute rhinosinusitis, 6) the clinician should obtain computed tomography of the paranasal sinuses in diagnosing or evaluating a patient with CRS or recurrent acute rhinosinusitis, and 7) clinicians should educate/counsel patients with CRS or recurrent acute rhinosinusitis regarding control measures. The panel offered as options that 1) clinicians may prescribe symptomatic relief in managing viral rhinosinusitis, 2) clinicians may prescribe symptomatic relief in managing ABRS, 3) observation without use of antibiotics is an option for selected adults with uncomplicated ABRS who have mild illness (mild pain and temperature <38.3 degrees C or 101 degrees F) and assurance of follow-up, 4) the clinician may obtain nasal endoscopy in diagnosing or evaluating a patient with CRS or recurrent acute rhinosinusitis, and 5) the clinician may obtain testing for allergy and immune function in evaluating a patient with CRS or recurrent acute rhinosinusitis. DISCLAIMER This clinical practice guideline is not intended as a sole source of guidance for managing adults with rhinosinusitis. Rather, it is designed to assist clinicians by providing an evidence-based framework for decision-making strategies. It is not intended to replace clinical judgment or establish a protocol for all individuals with this condition, and may not provide the only appropriate approach to diagnosing and managing this problem.

Mallants R, Jorissen M, Augustijns P. Effect of preservatives on ciliary beat frequency in human nasal epithelial cell culture: single versus multiple exposure. Int J Pharm 2007; 338:64-9. [PMID: 17324538 DOI: 10.1016/j.ijpharm.2007.01.029] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2006] [Revised: 01/13/2007] [Accepted: 01/16/2007] [Indexed: 11/23/2022]
Abstract
As preservatives may impair mucociliary clearance, we wanted to systematically study their time-dependent effect on the ciliary beat frequency (CBF) in human nasal epithelial cells (HNEC). CBF was determined using a high-speed digital imaging method. Five preservatives were selected including benzalkonium chloride, phenylethyl alcohol, methylparaben, propylparaben and chlorbutol. We were interested in the effect of these preservatives on CBF after single and repetitive exposure. Methylparaben (0.0033%), propylparaben (0.0017%) and chlorbutol (0.005%) did not impair CBF, neither after a single short-term exposure period, nor after a single long-term exposure period. Long-term exposure to benzalkonium chloride (0.001%), phenylethyl alcohol (0.125%) and a combination of methyl- and propylparaben (0.0033 and 0.0017%) significantly decreased CBF. After a short-term exposure period, CBF recovered for phenylethyl alcohol and the combination of methyl- and propylparaben. Benzalkonium chloride decreased CBF non-reversibly. For two compounds, the effect on CBF was evaluated after repetitive exposure during 15min for 5 consecutive days. Benzalkonium chloride resulted in ciliostasis for all concentrations tested after 5 days. Phenylethyl alcohol revealed a concentration-dependent effect on CBF, but no ciliostasis was observed. In conclusion, methylparaben, propylparaben and chlorbutol can be considered as cilio-friendly. Repetitive exposure revealed a cumulative effect on CBF for benzalkonium chloride and phenylethyl alcohol.

Abstract
PURPOSE OF REVIEW Patients with advanced head and neck cancer are being treated with chemo-radiotherapy, and life is being prolonged, with or without persistent disease, for longer than was previously. Hypercalcaemia may present in patients with advanced or disseminated head and neck cancer, and, as such, these patients may present to a larger variety of clinicians for advice concerning their symptoms and illness. Modes of presentation of hypercalcaemia and treatment strategies are reviewed. RECENT FINDINGS There were previously few large series of head and neck cancer patients diagnosed with hypercalcaemia, which may or may not have been related to their cancer being treated. Investigations, by way of blood/serum calcium level, may identify such patients. Patients with cancer-related hypercalcaemia have a poor prognosis, but many may respond temporarily to treatment when offered, with an improvement of their quality of life and death. SUMMARY Hypercalcaemia should and must be considered in all patients who have or possibly have a diagnosis of a head and neck cancer and who present unwell with symptoms of fatigue, lethargy and somnolence. Investigation must include serum calcium (corrected for serum albumin binding) and parathyroid hormone level. Patients may be treated by a combination of rehydration and bisulphonate therapy until the serum calcium is reduced to a level below 3 mmol/l. The majority of patients diagnosed with hypercalcaemia due to head and neck malignancy die of their diseases in the short term, but some may enjoy a prolongation of life with reasonable quality if diagnosed and treated aggressively.
