Abstract
BACKGROUND In recent years, significant improvements have been made in the treatment options for uncontrolled chronic rhinosinusitis (CRS) refractory to standard medical and surgical therapy. This is the result of a better understanding of the pathophysiology and the resulting development of biologicals for CRS with nasal polyps (CRSwNP). However, biologics are not (yet) available for all patients in Europe. OBJECTIVE Based on the session "Difficult-to-treat CRS, when biologics are not available" at the 29th Congress of the European Rhinologic Society (ERS) 2023 in Sofia, Bulgaria, the treatment options for uncontrolled CRS with the exclusion of biologics will be discussed. MATERIALS AND METHODS The content of the presentations "Is there a place for antibiotics?" "Indications for revision surgery," "Novel systemic treatment options," "Novel local treatment options," and "Phototherapy for nasal polyps" are outlined and supported by a review of the literature. RESULTS Various treatment options are available for managing uncontrolled CRS, even if biologic treatments are unavailable. Treatment options for type‑2 (T2) CRS include steroid rinses, repeated short-term oral steroids, steroid-eluting stents, and extended sinus surgery. In the case of nonsteroidal anti-inflammatory drug (NSAID)-exacerbated respiratory disease (NERD), acetylsalicylic acid (ASA) desensitization can be considered. Non-T2 endotypes or CRS without nasal polyps (CRSsNP) may benefit from several weeks of macrolides and xylitol rinses. CONCLUSION To accurately assess the efficacy of second-line therapies for treatment of difficult-to-treat CRS within an endotype-specific framework, additional controlled clinical trials are needed that take into account the heterogeneity of CRS endotypes.

Irradiation of human oral mucosa by 233 nm far UV-C LEDs for the safe inactivation of nosocomial pathogens. Sci Rep 2023; 13:22391. [PMID: 38104221 PMCID: PMC10725486 DOI: 10.1038/s41598-023-49745-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2023] [Accepted: 12/11/2023] [Indexed: 12/19/2023] Open
Abstract
The inactivation of multi resistant pathogens is an important clinical need. One approach is UV-C irradiation, which was previously not possible in vivo due to cytotoxicity. Recently, far UV-C irradiation at λ < 240 nm was successfully used on skin with negligible damage. A potential application site is the nasal vestibule, where MRSA accumulates and cannot be treated using antiseptics. We irradiated 3D mucosa models and excised human mucosa with 222 and 233 nm far UV-C in comparison to 254 nm and broadband UV-B. Eradication efficiency was evaluated by counting colony forming units; irritation potential was evaluated by hen's egg-chorioallantoic membrane assay and trans epithelial electrical resistance; cell viability was assessed by MTT. DNA damage and cell protective mechanisms were evaluated immunohistopathologically. On mucosa models, MRSA reduced by ≈ 5 log10 for 60 mJ/cm2 irradiation at 233 nm. A slightly increased cell viability was observed after 24 h. Lower doses showed lower irritation potential than the positive controls or commercial mouthwash, while 80 mJ/cm2 had strong irritation potential. DNA damage occurred only superficially and decreased after 24 h. On excised human mucosa, < 10% of keratinocytes were affected after 150 mJ/cm2 222 nm or 60 mJ/cm2 233 nm.

Clinical Efficacy and Safety of Low-Level Laser Therapy in Patients with Perennial Allergic Rhinitis: A Randomized, Double-Blind, Placebo-Controlled Trial. J Clin Med 2021; 10:jcm10040772. [PMID: 33671931 PMCID: PMC7919054 DOI: 10.3390/jcm10040772] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2021] [Revised: 02/11/2021] [Accepted: 02/11/2021] [Indexed: 11/25/2022] Open
Abstract
Allergic rhinitis (AR) is a common disease that interferes with the daily activities and reduces the quality of life. Conventional treatments often do not provide complete resolution of the symptoms, and many new treatment modalities have been tried. This study aimed to evaluate the efficacy and safety of low-level laser therapy (LLLT) for AR in a randomized, double-blind, placebo-controlled trial. Patients diagnosed with AR were randomly allocated to receive LLLT or sham treatment. The primary outcome was a change in the reflective total nasal symptom score (TNSS). The secondary outcome was quality of life scores assessed using the Rhinoconjunctivitis Quality of Life Questionnaire. Incidences of adverse events were also recorded. Among 67 randomized subjects, 41 subjects (22 in LLLT group and 19 in sham treatment group) were included for efficacy analysis. The LLLT group showed a significantly improved TNSS score compared to the sham treatment group for decreasing AR symptom severity (p = 0.011) and improving quality of life regarding nasal symptoms (p = 0.036) at the end of treatment. Throughout the treatment period, no severe adverse events occurred. This clinical trial showed that LLLT is an effective and safe option for the management of AR regarding symptom relief and quality of life improvement.

Open, prospective, multicenter study on postoperative intranasal phototherapy in nasal polyposis. Ir J Med Sci 2021; 191:375-383. [PMID: 33547613 DOI: 10.1007/s11845-021-02518-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/30/2020] [Accepted: 01/12/2021] [Indexed: 10/22/2022]
Abstract
BACKGROUND The therapeutic effect of ultraviolet (UV) light is generally attributed to its immunosuppressive and immunomodulatory effects. Since chronic inflammation is the major factor in the development of nasal polyposis, we have previously used mixed ultraviolet-visible light (mUV-VIS, Rhinolight®) phototherapy for the treatment of nasal polyps. AIMS In the present open, multicenter study, our aim was to delineate whether mUV-VIS applied postoperatively in vivo together with intranasal steroid treatment could reduce the recurrence of nasal polyps. METHODS After functional endoscopic sinus surgery, one group of patients received mUV-VIS light together with standard intranasal steroid (mometason furoate 2 × 200 μg) application for a 12-week treatment period, whereas the other patient group obtained only intranasal steroid for the same duration. We recorded nasal endoscopy images and obtained demographical and clinical data, total nasal score (TNS), and nasal obstruction symptom evaluation (NOSE). We performed acoustic rhinometry and measured nasal inspiratory peak flow. Follow-up was 12 months. RESULTS We found that the recurrence of nasal polyps was significantly diminished, and based on video-endoscopic measurements, the size and grade of recurrent polyps were significantly smaller in the phototherapy-receiving group. Nasal obstruction values and NOSE were significantly better throughout the follow-up period in the mUV-VIS light-treated group than in the intranasal steroid monotreatment group. CONCLUSIONS Rhinophototherapy together with standard nasal steroid application may have a supportive role in the treatment of recurrent bilateral nasal polyps.

Abstract
BACKGROUND Phototherapy with narrow-band ultraviolet B (narrow-band UVB) is clinically effective treatment for atopic dermatitis. In the present study, we examined the effects of intranasal irradiation with narrow-band UVB on nasal symptom, upregulation of histamine H1 receptor (H1R) gene expression and induction of DNA damage in the nasal mucosa of allergic rhinitis (AR) model rat. METHODS AR model rats were intranasally irradiated with 310 nm of narrow-band UVB. Nasal mucosal levels of H1R mRNA were measured using real-time quantitative reverse transcriptase (RT)-PCR. DNA damage was evaluated using cyclobutane pyrimidine dimer (CPD) immunostaining. RESULTS In toluene 2,4-diisocyanate (TDI)-sensitized rats, TDI provoked sneezes and H1R gene expression in the nasal mucosa. Intranasal pre-irradiation with 310 nm narrow-band UVB at doses of 600 and 1400, but not 200 mJ/cm2 significantly inhibited the number of sneezes and upregulation of H1R gene expression provoked by TDI. CPD-positive cells appeared in the nasal mucosa after intranasal narrow-band UVB irradiation at a dose of 1400, but not 200 and 600 mJ/cm2. The suppression of TDI-provoked sneezes and upregulation of H1R gene expression lasted 24 hours, but not 48 hours, after narrow-band UVB irradiation with a dose of 600 mJ/cm2. CONCLUSIONS Intranasal pre-irradiation with narrow-band UVB dose-dependently inhibited sneezes and upregulation of H1R gene expression of the nasal mucosa in AR model rats, suggesting that the inhibition of nasal upregulation of H1R gene expression suppressed nasal symptom. The suppression after narrow-band UVB irradiation at a dose of 600 mJ/cm2 was reversible without induction of DNA damage. These findings indicated that low-dose narrow-band UVB phototherapy could be effectively and safely used for AR treatment in a clinical setting. LEVEL OF EVIDENCE NA.

Abstract
With the largest viral loads in both symptomatic and asymptomatic patients with Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) present in the oral and nasal cavities, agents that act on these two areas have the potential for large therapeutic and prophylactic benefit. A literature review was conducted to elucidate the possible agents useful in treatment of SARS-CoV-2. These agents were evaluated for their current applications, adverse reactions, their current state of study, and any future considerations in their management of coronavirus disease 2019 (COVID-2019). Our review has found that, while there are many promising agents with proven efficacy in their in-vitro efficacy against SARS-CoV-2, more clinical trials and in-vivo studies, as well as safety trials, must be conducted before these agents can be effectively implemented.

Abstract
OBJECTIVE To provide a state of the art review of intranasal antiviral drug delivery and to discuss current applications, adverse reactions, and future considerations in the management of coronavirus disease 2019 (COVID-19). DATA SOURCES PubMed, Embase, and Clinicaltrials.gov search engines. REVIEW METHODS A structured search of the current literature was performed of dates up to and including April 2020. Search terms were queried as related to topics of antiviral agents and intranasal applications. A series of video conferences was convened among experts in otolaryngology, infectious diseases, public health, pharmacology, and virology to review the literature and discuss relevant findings. CONCLUSIONS Intranasal drug delivery for antiviral agents has been studied for many years. Several agents have broad-spectrum antiviral activity, but they still require human safety and efficacy trials prior to implementation. Intranasal drug delivery has potential relevance for future clinical trials in the settings of disease spread prevention and treatment of SARS-CoV-2 and other viral diseases. IMPLICATIONS FOR PRACTICE Intranasal drug delivery represents an important area of research for COVID-19 and other viral diseases. The consideration of any potential adverse reactions is paramount.

Effects of irradiation with narrowband-ultraviolet B on up-regulation of histamine H 1 receptor mRNA and induction of apoptosis in HeLa cells and nasal mucosa of rats. J Pharmacol Sci 2018; 138:54-62. [PMID: 30301597 DOI: 10.1016/j.jphs.2018.08.011] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2017] [Revised: 08/21/2018] [Accepted: 08/28/2018] [Indexed: 01/01/2023] Open
Abstract
Narrowband-ultraviolet B (NB-UVB) phototherapy is used for the treatment of atopic dermatitis. Previously, we reported that irradiation with 200 mJ/cm2 of 310 nm NB-UVB suppressed phorbol-12-myristate-13-acetate (PMA)-induced up-regulation of histamine H1 receptor (H1R) gene expression without induction of apoptosis in HeLa cells. However, the effect of NB-UVB irradiation on nasal symptoms is still unclear. Here, we show that low dose irradiation with 310 nm NB-UVB alleviates nasal symptoms in toluene 2,4-diisocyanate (TDI)-sensitized allergy model rats. Irradiation with 310 nm NB-UVB suppressed PMA-induced H1R mRNA up-regulation in HeLa cells dose-dependently at doses of 75-200 mJ/cm2 and reversibly at a dose of 150 mJ/cm2 without induction of apoptosis. While, at doses of more than 200 mJ/cm2, irradiation with 310 nm NB-UVB induced apoptosis. Western blot analysis showed that the suppressive effect of NB-UVB irradiation on H1R gene expression was through the inhibition of ERK phosphorylation. In TDI-sensitized rat, intranasal irradiation with 310 nm NB-UVB at an estimated dose of 100 mJ/cm2 once a day for three days suppressed TDI-induced sneezes and up-regulation of H1R mRNA in nasal mucosa without induction of apoptosis. These findings suggest that repeated intranasal irradiation with low dose of NB-UVB could be clinically used as phototherapy of AR.

Abstract
PURPOSE The aim of this pilot study was to assess the feasibility and value of wide-field autofluorescence imaging (AFI) for the detection of bladder cancer during transurethral resection of the bladder (TUR-B). METHODS For imaging, the D-Light/AF System (Karl Storz GmbH, Tuttlingen, Germany) and a customized band pass filter (≈ 480-780 nm) at the eyepiece of the endoscope were used. The excitation light wavelength was 440 nm. Representative spectral measurements of tissue autofluorescence (AF) were performed using a spectrometer attached behind the AF band pass filter in selected patients. During TUR-B, cystoscopy was performed in white light (WL) followed by wide-field AFI. Lesions were classified as suspicious or normal using either modality. RESULTS Representative spectral measurements using excitation at a wavelength of 440 nm resulted in significantly lower fluorescence intensity of malignant versus non-malignant tissue. Overall, 56 lesions (30 cancerous and 26 non-malignant) in 25 patients were assessed and classified by wide-field AFI. Papillary tumors as well as flat lesions lacked the green fluorescence seen in normal urothelium, thus emerging as "brown-reddish" areas. When compared with histopathological findings, the pooled per-lesion sensitivity and specificity for AF were 96.7 and 53.8%, respectively. For WL these values were 86.7 and 69.2%, respectively. CONCLUSION Wide-field AFI imaging during TUR-B is simple and easy to use. Our preliminary data suggest that AFI has the potential to increase the detection rates of bladder tumors compared with WL without the need of intravesical instillation prior to the procedure.

Abstract
Previous published results have revealed that Rhinolight® intranasal phototherapy is safe and effective in intermittent allergic rhinitis. The present objective was to assess whether phototherapy is also safe and effective in persistent allergic rhinitis. Thirty-four patients with persistent allergic rhinitis were randomized into two groups; twenty-five subjects completed the study. The Rhinolight® group was treated with a combination of UV-B, UV-A, and high-intensity visible light, while the placebo group received low-intensity visible white light intranasal phototherapy on a total of 13 occasions in 6 weeks. The assessment was based on the diary of symptoms, nasal inspiratory peak flow, quantitative smell threshold, mucociliary transport function, and ICAM-1 expression of the epithelial cells. All nasal symptom scores and nasal inspiratory peak flow measurements improved significantly in the Rhinolight® group relative to the placebo group and this finding persisted after 4 weeks of follow-up. The smell and mucociliary functions did not change significantly in either group. The number of ICAM-1 positive cells decreased non-significantly in the Rhinolight® group. No severe side-effects were reported during the treatment period. These results suggest that Rhinolight® treatment is safe and effective in persistent allergic rhinitis.

Abstract
Objectives To investigate the effect of rhinophototherapy with medical therapy on quality of life in persistent allergic rhinitis. Methods A prospective, randomized study was being performed between December 2009 and March 2010. The study included 65 patients with persistent allergic rhinitis. The diagnosis was confirmed with positive skin tests. All of the patients had house dust mite allergies. We divided the patients into two groups. First group (n=33) was given topical mometasone furoate 200 mcg/day and levocetirizine 5 mg/day for a month. Rhinophototherapy was applied with the same medical therapy to the second group (n=32), twice a week for three weeks continuously. Rhinophototherapy included visible light, ultraviolet A and ultraviolet B. We evaluated patients before the treatment, at the first month and at the third month after treatment with rhinoconjunctivitis quality of life questionnaire, nasal symptom scores and visual analogue scale (VAS) scores. Results Improvements of all variables of the quality of life questionnaire, nasal symptom scores and VAS were statistically significant in the second group both on the first and the third months when compared with the first group. Conclusion Allergic rhinitis is a social problem and impairs quality of life. Rhinophototherapy with medical therapy improves the quality of life in allergic rhinitis.

Abstract
People can get oral cancers from UV (290-400 nm) exposures. Besides high outdoor UV exposures, high indoor UV exposures to oral tissues can occur when consumers use UV-emitting tanning devices to either tan or whiten their teeth. We compared the carcinogenic risks of skin to oral tissue cells after UVB (290-320 nm) exposures using commercially available 3D-engineered models for human skin (EpiDerm™), gingival (EpiGing™) and oral (EpiOral™) tissues. To compare the relative carcinogenic risks, we investigated the release of cytokines, initial DNA damage in the form of cyclobutane pyrimidine dimers (CPDs), repair of CPDs and apoptotic cell numbers. We measured cytokine release using cytometric beads with flow cytometry and previously developed a fluorescent immunohistochemical assay to quantify simultaneously CPD repair rates and apoptotic cell numbers. We found that interleukin-8 (IL-8) release and the initial CPDs are significantly higher, whereas the CPD repair rates and apoptotic cell numbers are significantly lower for oral compared with skin tissue cells. Thus, the increased release of the inflammatory cytokine IL-8 along with inefficient CPD repair and decreased death rates for oral compared with skin tissue cells suggests that mutations are accumulating in the surviving population of oral cells increasing people's risks for getting oral cancers.

Abstract
We developed a triple-labeling immunofluorescence technique that simultaneously identifies total DNA (DAPI), DNA damage (antibodies), and dead cells [terminal deoxynucleotidyl transferase-mediated dUTP nick end-labeling (TUNEL)-positive cells] and a method that semiquantifies DNA damage in paraffin-embedded tissues. Using this technique in combination with our analysis method, scientists can now simultaneously detect and compare the relative amounts of DNA damage of almost any kind (except single-strand and double-strand breaks), using indirect fluorescent antibody labeling, in both normal and dying cells of different tissues. Simultaneous labeling of DNA damage and dead or TUNEL-positive cells can reduce processing costs and analysis time, and can lead to discoveries concerning how cells die from different DNA damages. We used increasing doses of UV (290 to 400 nm) radiation to create DNA damage in the form of cyclobutane pyrimidine dimers and 6-4 photoproducts that kill some of the cells in 3-dimensional tissue-engineered skin and vaginal samples. We describe a protocol that reliably detects and semiquantifies DNA damage in both normal and apoptotic cells. We show this triple-labeling immunofluorescence technique and analysis method yields linear UV dose response curves for damage to DNA bases that allows semiquantification of cyclobutane pyrimidine dimers and calculation of its repair rate (T=1 and 24 h), whereas TUNEL allows quantification of the number of apoptotic cells. Scientists can now create beautiful fluorescent pictures that simultaneously detect DNA damage in both normal and apoptotic cells to assess and semiquantify the damage to understand better how different insults lead to the cell's demise.

Abstract
Ultraviolet radiation (UVR) exposure to internal tissues for diagnostic, therapeutic and cosmetic procedures has increased dramatically over the past decade. The greatest increase in UVR exposure of internal tissues occurs in the cosmetic industry where it is combined with oxidizing agents for teeth whitening, often in conjunction with indoor tanning. To address potential carcinogenic risks of these procedures, we analyzed the formation and repair of the DNA photoproducts associated with the signature mutations of UVR. Radioimmunoassay was used to quantify the induction and repair of cyclobutane pyrimidine dimers and pyrimidine(6-4)pyrimidone photoproducts in DNA purified from three reconstructed tissues, EpiDerm(TM) , EpiGingival(TM) and EpiOral(TM) . We observed comparable levels of DNA damage in all tissues immediately after UVR exposure. In contrast, repair was significantly reduced in both oral tissues compared with EpiDerm(TM) . Our data suggest that UVR exposure of oral tissues can result in accumulation of DNA damage and increase the risk for carcinoma and melanoma of the mouth. Because NER is a broad-spectrum defense against DNA damage caused by a variety of agents in addition to UVR, our data suggest that the relatively low NER efficiency observed in oral tissues may have wide-ranging consequences in this highly exposed environment.

Abstract
Allergic rhinitis is a high-incidence allergic inflammation of the nasal airways that impacts quality of life. Of the numerous therapies used to treat allergic rhinitis, intranasal phototherapy has emerged as a promising new treatment modality for inflammatory airway disease. Phototherapy is widely used for the treatment of immune-mediated skin diseases because its profound immunosuppressive effect inhibits hypersensitivity reactions in the skin. Intranasal phototherapy using a combination of Ultraviolet-A (UVA) and Ultraviolet-B (UVB) plus Visible light (VIS) has been shown to suppress the clinical symptoms of allergic rhinitis, but limited data regarding its adverse effects on the nasal mucosa currently exists. In this study, we demonstrate that UV displays no harmful effects on the nasal mucosa cells of rabbits following 2 weeks of intranasal phototherapy.

Abstract
We recently showed that intranasal phototherapy represents an efficient therapeutic modality for the treatment of patients with seasonal allergic rhinitis (SAR). The aim of this pilot study was to compare the efficacy of intranasal phototherapy with that of the new generation antihistamine fexofenadine HCl in SAR. A randomized open study was conducted in patients with a history of moderate-to-severe ragweed-induced SAR. Thirty-one patients were randomly assigned to receive either intranasal irradiation three times a week for 2 weeks, or 180 mg fexofenadine HCl per day for 2 weeks. Each patient kept a diary of symptoms for nasal obstruction, nasal itching, rhinorrhea, sneezing and palate itching. Total nasal score (TNS), a sum of scores for nasal symptoms, was also calculated. In the rhinophototherapy group the individual scores significantly decreased compared with baseline for all of the parameters. In the fexofenadine HCl group none of the scores improved significantly at the end of the treatment except sneezing. TNS was significantly decreased in the rhinophototherapy group, but no significant change was observed in the fexofenadine HCl group after 2 weeks of treatment. In conclusion, we found that intranasal phototherapy is more efficient than fexofenadine HCl in reducing clinical symptoms for SAR.

Abstract
Background: Phototherapy has a profound immunosuppressive effect, and phototherapeutic methods using both ultraviolet (UV) and visible light are therefore widely used for the therapy of various inflammatory skin diseases. It is also proposed that phototherapy, using a combination of UV-A (25%), UV-B (5%) and visible light (70%), may represent a therapeutic alternative in patients with allergic rhinitis. Method: Seventy-nine patients were randomly assigned to receive either a combination of UV-A (25%), UV-B (5%) and visible light (70%), in the phototherapy group, or low-intensity visible light, in the control group. The efficacy of treatment was assessed by means of total nasal symptom score before treatment and 1 month after the end of treatment. Results: Total nasal scores decreased in both groups but the decrease was highly significant in the active treatment group when compared with the placebo (p < 0.001). Conclusions: This study demonstrates that phototherapy may be an effective modality in the treatment of allergic rhinitis especially in cases of which commonly used drugs either are contraindicated and/or have insufficient efficacy.
