Elevated B cell-activating factor (BAFF) in children with allergic rhinitis

ObjectiveTo evaluate the possible role of B cell-activating factor (BAFF) in children with allergic rhinitis (AR).MethodsTwenty-four AR children and 20 normal children were enrolled in this study and nasal lavage and serum were collected. The nasal and serum levels of BAFF were measured using enzyme-linked immunosorbent assay (ELISA). The relationship between serum BAFF and immunoglobulin A (IgA) was evaluated in AR children.ResultsOur results showed that the nasal and serum levels of BAFF were significantly increased in AR children compared with controls (p < 0.05). The nasal and serum levels of BAFF in AR children were significantly associated with disease severity (p < 0.05). Moreover, the level of serum BAFF was negatively related to serum IgA level (p < 0.05).ConclusionOur findings show BAFF expression was significantly increased and related to disease severity, indicating BAFF may be implicated in new treatment modalities for AR children.     

Relationship between exhaled nitric oxide and biomarkers of atopy in children and adolescents with allergic rhinitis

IntroductionMeasurement of the exhaled nitric oxide fraction (FeNO) has been proposed as an indirect and non-invasive method to detect eosinophilic airway inflammation. Allergic rhinitis (AR) is frequently associated with high levels of FeNO. Allergic sensitization can contribute to the recruitment of eosinophils in the airway and the consequent increase in FeNO.ObjectiveTo correlate FeNO values with inflammatory and atopic sensitization biomarkers in patients with AR.Patients and methodsObservational, analytical, cross-sectional study. Children and adolescents with AR without asthma were included. FeNO, blood eosinophil count, total serum IgE were determined and skin tests with aeroallergens were performed by calculating the scores for PPC1 (number of positive allergens), STS2 (sum of millimeters of positive papules) and the atopy index (ratio between STS2/STS1). Spearman's correlation test was used between FeNO and variables of inflammation and atopy.ResultsTwenty-eight patients between 6 and 17 years old were included. There was a significant positive correlation between FeNO and blood eosinophils (r = .38; p = .047) and between FeNO and the atopy index (r = .40; p = .03). No correlation was found between FeNO and total serum IgE (r = .24; p = .21), STS1 (r = .20; p = .32) and STS2 (r = .34; p = .08).ConclusionIn children and adolescents with AR, FeNO was correlated with the atopy index and the blood eosinophil count. These last biomarkers could be used as alternatives for FeNO as biomarkers of lower airway inflammation in patients with AR.     

Serum 25-hydroxyvitamin D3 levels in children with allergic or nonallergic rhinitis

ObjectivesThe relationship between vitamin D and allergic diseases such as asthma and atopic dermatitis is shown in several studies. But there is a lack of knowledge about vitamin D status in children with allergic rhinitis (AR). We aimed to investigate serum vitamin D levels of children with AR or nonallergic rhinitis (NAR), to compare with normal subjects and to evaluate the relationship between vitamin D and the severity of AR.MethodsThe study included a total of 141 children (76 patients with rhinitis and 65 control subjects), who applied to the Pediatric allergy immunology outpatient. Skin prick tests were performed using the same antigens for all patients. Serum 25-hydroxyvitamin D3 (25OHD3) levels were measured. AR was classified according to the ARIA guidelines.ResultsMean 25OHD3 levels were 18.07 ± 6.1 ng/mL in the AR group, 14.81 ± 4.86 in the NAR, and 24.03 ± 9.43 ng/mL in the control group. These differences among groups were statistically significant (p = 0.001). Vitamin D status was determined as deficient in 32 (66.7%) patients, insufficient in 14 (29.2%) and normal in 2 (4.2%) of the AR group. These frequencies for NAR and control groups are 25 (89.3%), 3 (10.7%), 0, and 25 (38.5%), 32 (49.2%), 8 (12.3%), respectively. Vitamin D status was found to be different among groups (p = 0.001). There were not any association between 25OHD3 levels and allergen sensitivity (p > 0.05). The comparison of the mean 25OHD3 levels according to the severity and duration of AR did not detect statistically significant difference among groups (respectively, p = 0.384, p = 0.23 Denburg J, Fokkens WJ, Togias A5).ConclusionsThe mean serum 25OHD3 levels of the children both with AR and NAR were lower than control group. No association between 25OHD3 levels and allergen sensitivities was found in our study. We did not find any relationship between 25OHD3 levels and the severity and duration of allergic rhinitis     

Efficacy of nasal irrigation with hypertonic saline on chronic rhinosinusitis: systematic review and meta-analysis

IntroductionCurrently, several different concentrations of saline are recommended for use in nasal irrigation. Increasing studies show that nasal irrigation with hypertonic saline is more effective than traditional saline in the treatment of rhinosinusitis, but there have been few systematic analyses of the effect of nasal irrigation with hypertonic saline on chronic rhinosinusitis.ObjectiveWe sought to compare the effects of hypertonic saline and isotonic saline in the treatment of rhinosinusitis in order to provide a reference for clinical nasal irrigation for chronic rhinosinusitis treatment.MethodsMedline, cochrane library, EMBASE, PubMed, Chinese biomedical journal database, China national knowledge infrastructure, Wanfang database, and other databases were searched, and the searching was supplemented by manual searches for relevant references to treatment of rhinosinusitis by saline nasal irrigation. The last retrieval date was March 2018. The included studies were evaluated for quality, and data were extracted for meta-analysis using RevMan 5.3.ResultsSeven studies were included. Effects favoring hypertonic saline on nasal symptoms were greater in 4 subgroups. These were (1) patients with nasal secretion (SMD = 1.52; 95% CI: 1.04, 2.00; p < 0.01), (2) patients with congestion (SMD = 1.52; 95% CI: 1.04, 2.00; p < 0.01), (3) patients with headache (SMD = 0.82; 95% CI: 0.38, 1.26; p < 0.01), (4) patients with overall symptomatic relief (SMD = 1.63; 95% CI: 0.83, 2.44; p < 0.01). However, no difference was shown in smell improvement (SMD = 0.47; 95% CI: −0.65, 1.59; p = 0.41) and radiologic scores improvement (SMD = 2.44; 95% CI: -3.14, 8.02; p < 0.01). Besides, hypertonic saline showed greater improvement in mucociliary clearance time scores than did the isotonic saline group (SMD = 1.19; 95% CI: 0.78, 1.60; p < 0.01). Hypertonic saline brought greater minor adverse effects.ConclusionCompared with isotonic saline, hypertonic saline nasal irrigation for the treatment of chronic rhinosinusitis is significantly more effective and has mild side effects in improving nasal symptoms and ciliary movement, but there is no significant difference in imaging findings and smell improvement. Although hypertonic saline is worthy of widespread use in clinical practice, it is still necessary to further study the exact manner and concentration of nasal irrigation.     

Steroid vs. antibiotic impregnated absorbable nasal packing for wound healing after endoscopic sinus surgery: a randomized,double blind,placebo-controlled study

IntroductionEndoscopic sinus surgery can lead to crusting or synechiae formation, which can affect the healing process.ObjectiveThe aim of our study was to compare the influence of steroid versus antibiotic versus saline solution impregnated absorbable nasal spacers on postoperative wound healing and patient satisfaction.MethodsEighty patients, 33 women and 47 men, were enrolled in this study. At the end of the surgery, two pieces of 4 cm biodegradable material were applied in each ethmoid cavity. One of them was impregnated with saline solution, while the second one with steroid, or with antibiotic.ResultsWe observed statistically significant differences in the Lund–Kennedy score between the control and both treatment groups: for the Antibiotic-group on days 10 and 30 (p = 0.009; p = 0.009) and for the Steroid-group on day 90 (p = 0.008). The extended endoscopic appearance of nasal mucosa indicated statistically significant differences in crust formation on day 10 comparing the steroid and control dressing (p = 0.025), in secretion type on days 10 and 30 comparing the antibiotic and control dressing (p = 0.003; p = 0.016) and additionally for steroid and control on day 90 (p = 0.046). On Day 90 we observed statistically significant differences in the absence of mucosal edema in the S-group compared to controls (p = 0.007).ConclusionsThe results of this study reveal the significant positive influence of steroid- and antibiotic-impregnated biodegradable nasal packing on the postoperative healing process and patient satisfaction compared to the saline soaked dressing.     

Nasal nitric oxide in the inferior turbinate surface decreases with intranasal steroids in allergic rhinitis: A prospective study

ObjectiveIt remains controversial whether nasal nitric oxide (NO) serves as a reliable parameter to evaluate treatment efficacy in patients with allergic rhinitis (AR). The measurement of local nasal NO levels has been shown to be a sensitive marker for the diagnosis of symptomatic AR patients. Here we assessed the applicability of nasal NO to evaluations of the efficacy of intranasal steroids (INS) in a prospective design.MethodsWe enrolled 25 patients with perennial AR and 10 age-matched healthy participants. The AR patients received fluticasone furoate (FF) once daily for 2 months. Fractional exhaled NO and nasal NO measurements were carried out using an electrochemical analyzer at pretreatment and at 2 weeks and 2 months after treatment. Nasal NO levels were directly measured at two different areas of the nasal cavity: the surface of the inferior turbinate (IT area) and the front of the middle meatus (MM area). Subjective nasal symptoms were also recorded at each visit.ResultsThe mean total nasal symptom score in the AR patients decreased significantly after FF treatment (p < 0.0001). The mean nasal NO levels in the IT area in the AR patients were significantly higher at pretreatment than those of the healthy participants (109 vs. 62.5 ppb, respectively; p < 0.001). After FF administration, the nasal NO levels in the IT area of the AR group showed a significant reduction at both 2 weeks and 2 months (79.1 and 71.9 ppb, respectively; p < 0.05 and p < 0.01). There was no significant difference in nasal NO levels in the MM area between the controls and the AR group at any visit timepoint. When the ratio of the MM area to the IT area (MM/IT ratio) was plotted for each subject, the untreated AR patients showed a marked decrease in the ratio, whereas after the FF treatment, the AR patients' mean MM/IT ratios showed a significant increase. No significant difference compared to the control group existed at 2 months.ConclusionNasal NO measurement around the inferior turbinate is an objective measure to evaluate allergic conditions and is useful to monitor therapeutic effects of INS.     

Immediate effects of a rhino-pharyngeal clearance protocol in nasal obstruction and middle ear condition of children under 3 years of age with upper respiratory infections: A randomized controlled trial

Introduction and objectivesChildren up to 2 years old are at high risk of respiratory infections and nasal irrigation is often prescribed. Yet, to date there is no sufficient knowledge about its immediate effects on the nasopharynx and middle ear. Therefore, this study aimed to analyze the effect of a rhino-pharyngeal clearance intervention protocol on nasal obstruction and middle ear condition in children under 3 years of age with URTI.Materials and methodsRandomized controlled trial in a day-care centre of Porto, including 44 children randomized to Intervention Group (IG) and Control Group (CG). Nasal auscultation and tympanometry were performed at baseline (M0) as well as after the intervention (M1), which consisted of nasal irrigation (NaCl .9%) followed by a forced nasal inspiration in the IG, and after 30 min of normal activities, in the CG.ResultsIn M1 there was a lower frequency of children classified as having an obstructed nasal sound in the IG when compared to the CG (IG = 33.3%; CG = 68.4%; p = 0.042). We also observed an improvement of mean peak pressure (PP) in the IG (Left ear: M0 = −124daPa; M1 = −92daPa; p = 0.022. Right ear: M0 = −102daPa; M1 = −77daPa; p = 0.021), which was not observed in the CG (Left ear: M0 = −105daPa; M1 = −115daPa; p = 0.485. Right ear: M0 = −105daPa; M1 = −131daPa; p = 0.105). There were no significant results concerning the compliance of the tympanic membrane.ConclusionsThe rhino-pharyngeal clearance improved the nasal obstruction and PP of the middle ear of children under 3 years of age with URTI.     

Effect of oral steroids on olfactory function in chronic rhinosinusitis with nasal polyps

AimsThe present study aimed to investigate the effects of oral steroids on olfactory disturbances in patients with chronic rhinosinusitis with nasal polyps (CRSwNP).Material and methodsThis is a prospective randomized non-blinded study. Selected CRSwNP patients (n = 140), with hyposmia, were devided into two groups; group A received a 7-day course of oral steroids with a 12-weeks course of nasal steroids and douching; group B received a 12-weeks course of nasal steroids and douching. Assessment included Sniffin’ Sticks scores, visual analogue scale score for olfaction and discomfort (VASsmell, VASdis), the Sinonasal Outcome Test-22, Greek-version (SNOT22-Gr) and the endoscopic appearance (EAS).ObjectivesThe main objective was to compare the olfactory effect of the different therapy in group A and group B, at 2, 12 and 24 weeks. Accessory objectives included the comparison of EAS, VASdis and SNOT22-Gr between groups, the evaluation of the therapeutic outcome duration, and, the investigation of potential correlation between the evaluated parameters.ResultsThe 2-weeks evaluation showed a significant statistical difference (P < 0.001) for all parameters except VASdis. Olfactory outcomes (Sniffin’ Sticks and VASsmell scale scores) were found significantly better in group A at the 24-weeks evaluation (P < 0.001). Within groups, the therapeutic result remained stable between the 12-weeks and 24-weeks evaluation (P > 0.05). Sniffin’ Sticks score was strongly correlated at 12-weeks evaluation with EAS (rho = 0.58, P < 0.001).ConclusionOur results suggest that a combination treatment of oral and nasal steroids in well-selected patients with CRSwNP may result in early olfaction restoration with a possible long-term effect.     

Peripheral Th17/Treg cell-mediated immunity imbalance in allergic rhinitis patients,

IntroductionAllergic rhinitis (AR) is an IgE-mediated non-infectious disease of the nasal mucosa following contact with allergens.ObjectiveTo investigate the peripheral Th17 cells and CD4 + CD25 + Foxp3 + regulatory T (Treg) cells and the expression of cytokines in the serum of AR patients.MethodsThe peripheral blood of 14 patients with AR (AR group) and six healthy subjects (control group) was collected from March to May of 2012. Flow cytometry was performed to detect the Th17 cells and Treg cells, and enzyme-linked immunosorbent assay (ELISA) to measure the serum levels of IL-17 and TGF-&#946;1.ResultsThe proportion of Th17 cells in the AR group was markedly higher than that in the control group (p < 0.01). The proportion of Treg cells in the AR group was also dramatically reduced when compared with the control group (p < 0.01). In the AR group, serum IL-17 levels were markedly higher than those in the control group (p < 0.01). In the AR group, serum TGF-&#946;1 levels were significantly lower than those in the control group (p < 0.01).ConclusionThe imbalance of peripheral Th17/Treg cells plays an important role in the pathogenesis of AR.© 2014 Associação Brasileira de Otorrinolaringologia e Cirurgia Cérvico-Facial.

Effect of topical corticosteroids on nasal patency after acute positive airway pressure exposure

IntroductionNasal congestion and obstruction are reported in the majority of continuous positive airway pressure users and are frequently cited as reasons for noncompliance. Baseline inflammation due to allergic rhinitis could increase or exacerbate the inflammatory effect of high airflow in the nasal cavity as the result of continuous positive airway pressure and lead to greater continuous positive airway pressure intolerance. In this setting, intranasal steroids would be expected to counteract the nasal inflammation caused by allergic rhinitis and/or continuous positive airway pressure.ObjectiveThe aim of the present study is to evaluate the effects of topical corticosteroid use on nasal patency after acute exposure to positive pressure.MethodsTen individuals with allergic rhinitis were exposed to 1 h of continuous airway pressure (15 cm H₂O) in the nasal cavity, delivered by a continuous positive airway pressure device. Visual analog scale, nasal obstruction symptom evaluation scale, acoustic rhinometry and peak nasal inspiratory flow were performed before and after the intervention. After 4 weeks topical nasal steroid (budesonide) application, positive pressure exposure was repeated as well as the first assessments.ResultsPatients reported a statistically significant improvement both on the visual analog (p = 0.013) and obstruction symptom evaluation scales (p < 0.01). Furthermore, objective measurements were improved as well, with increased nasal cavity volume on acoustic rhinometry (p = 0.02) and increased peak nasal inspiratory flow (p = 0.012), after corticosteroid treatment.ConclusionIn patients with allergic rhinitis, intranasal corticosteroid therapy improved objective and subjective parameters of nasal patency after acute exposure of the nasal cavity to positive pressure.     

Clinical symptoms of chronic rhinosinusitis with nasal polyps (eosinophilic and non-eosinophilic) are related to sinus computed tomography but not to endoscopic findings

BackgroundIn the clinical assessment of chronic rhinosinusitis with nasal polyps (CRSwNP), evaluation of symptoms, nasoendoscopy findings and sinus computed tomography (CT) scan staging is employed in the management plan. Although prior studies have been done to assess the correlation of the three modalities in CRSwNP, such evaluation in patients with eosinophilic and non-eosinophilic types of CRSwNP requires further investigation. The aim of this study was to correlate the sinus CT scan staging to symptom and endoscopic scores in both types of CRSwNP.Material and methodPatients with CRSwNP were classified into 2 types, eosinophilic and non-eosinophilic. Both types were assessed by Sino-Nasal Outcome Test 22 (SNOT-22) symptom score, nasal endoscopy Lund Kennedy grading (LK) score and sinus CT Lund Mackay (LM) staging score. All three modalities were correlated.ResultsForty-four patients were recruited for this study. There was significant correlation between sinus CT and symptom scores in the eosinophilic (r = .51, p = .031) and the non-eosinophilic (r = .76, p < .001) types. There was no significant correlation between symptom and nasoendoscopic scores in the eosinophilic (r = .12, p = .641) and the non-eosinophilic (r = .22, p = .276) types. There was also no significant correlation between sinus CT and nasoendoscopic scores in the eosinophilic (r = .20, p = .418) and the non-eosinophilic (r = .14, p = .508) types.ConclusionsSinus CT staging correlates well with the symptom score for both the eosinophilic and the non-eosinophilic types of CRSwNP. The good correlation suggests both modalities are a reliable guide for their evaluation and management planning.     

Predictor parameters for poor prognosis in patients with sudden sensorineural hearing loss: fibrinogen to albumin ratio vs C-reactive protein to albumin ratio

IntroductionPrognosis of sudden sensorineural hearing loss may be predicted using several parameters of laboratory blood analysis.ObjectiveTo identify and investigate the most significant indicator parameters related to the poor prognosis of sudden sensorineural hearing loss.MethodsEighty-eight patients were included, and three groups were constituted: non-recovery group with14 patients, recovery group with 33 patients and control group with 41 individuals. We compared fibrinogen-to-albumin ratio, C-reactive protein-to-albumin ratio, neutrophil-to-lymphocyte ratio, platelet-to-lymphocyte ratio, white blood cell and hemoglobin of the groups. Then, we investigated the most significant indicator parameters related to the poor prognosis of sudden hearing loss.ResultsThe mean hemoglobin, mean platelet-lymphocyte ratio and median white blood cell values did not significantly differ among three groups (p = 0.36, p = 0.86 and p = 0.79, respectively). A significant difference of median fibrinogen-albumin ratio, C-reactive protein-albumin ratio, neutrophil-to-lymphocyte ratio was evident among three groups (p < 0.001, p = 0.003 and p = 0.002, respectively). Median fibrinogen-albumin ratio, C-reactive protein-albumin ratio and neutrophil-to-lymphocyte ratio values were significantly greater in the non-recovery group, compared with the controls (p < 0.001, p = 0.003 and p = 0.005, respectively). Median fibrinogen-to-albumin ratio, C-reactive protein-to-albumin ratio and neutrophil-to-lymphocyte ratio were significantly greater in the recovery group, compared with the controls (p < 0.001, p = 0.013 and p = 0.005, respectively). Moreover, the median fibrinogen-albumin ratio was significantly greater in the non-recovery group compared with the recovery group (p = 0.017). However, no statistically significant difference of median C-reactive protein-albumin ratio, neutrophil-to-lymphocyte was evident between the non-recovery and recovery groups (p = 0.15).ConclusionIncreased levels of fibrinogen-albumin ratio may be predictive for poor prognosis in patients with sudden sensorineural hearing loss.     

The systolic pulmonary artery pressure and the E/e’ ratio decrease after septoplasty in patients with grade 2 and 3 pure nasal septal deviation

IntroductionNasal septal deviation may contribute to a wide range of symptoms including nasal obstruction, headache, increased secretion, crusting, mucosal damage, and loss of taste and smell. Excessive increase in the respiratory resistance, as seen in nasal septal deviation, results in reduced lung ventilation, thereby potentially leading to hypoxia, hypercapnia, pulmonary vasoconstriction. The deformities in the nasal cavity can be associated with major respiratory and circulatory system diseases.ObjectiveTo investigate cardiovascular effects of septoplasty by comparing pre- and postoperative transthoracic echocardiography findings in nasal septal deviation patients undergoing septoplasty.MethodsThe prospective study included 35 patients with moderate and severe nasal septal deviation (mean age, 23.91 ± 7.01) who underwent septoplasty. The Turkish version of the nasal obstruction symptom evaluation, NOSE questionnaire, was administered to each participant both pre- and postoperatively in order to assess their views on the severity of nasal septal deviation, the effect of nasal obstruction, and the effectiveness of surgical outcomes. A comprehensive transthoracic echocardiography examination was performed both preoperatively and at three months postoperatively for each patient and the findings were compared among patients.ResultsMean preoperative NOSE score was 17.34 ± 1.62 and the mean postoperative score was 2.62 ± 1.68 (p = 0.00). Mean preoperative systolic pulmonary artery pressure value was 22.34 ± 4.31 mmHg and postoperative value was 18.90 ± 3.77 mmHg (p = 0.00). Mean E/e’ ratio was 5.33 ± 1.00 preoperatively and was 5.01 ± 0.90 postoperatively (p = 0.01). The NOSE scores, systolic pulmonary artery pressure values, and the E/e’ ratios decreased significantly after septoplasty (p < 0.05 for all), whereas no significant difference was found in other transthoracic echocardiography parameters (p > 0.05).ConclusionThe decrease in NOSE scores following septoplasty indicated that the satisfaction levels of the patients were increased. Upper airway obstruction secondary to nasal septal deviation may be a cardiovascular risk factor and may affect transthoracic echocardiography measurements. Moreover, the significant decrease in the systolic pulmonary artery pressure value and E/e’s ratio following septoplasty indicated that negative echocardiographic findings may be prevented by this surgery.     

Endoscopic sinus surgery with and without computer assisted navigation: A retrospective study

ObjectiveIn the last years endoscopic sinus surgery (ESS) is improved with the introduction of computer assisted navigation (CAN). In this retrospective study we evaluated the usefulness of CAN in endoscopic sinus surgery and studied its advantages over conventional endoscopic sinus surgery.MethodsWe retrospectively reviewed the records of 96 patients with chronic rhinosinusitis (CRS). 48 patients undergoing endoscopic sinus surgery with surgical navigation (A group) and other 48 without navigation (B group). Data about percentage of complications, olfactory function (Visual Analogue Scale), Sino-nasal Outcomes Test (SNOT-22), Rhinosinusitis Quality of Life (RhinoQoL), recurrence (CT Lund–Mackay score), total nasal resistance (rhinomanometry) and duration of the intervention were collected and analyzed.ResultsA group evidenced a decrease of recurrence rate (p = 0.009), a reduction of total nasal resistance (p = 0.007), of frontal recess stenosis (p = 0.04) and of nasal symptomatology (p = 0.008). QoL had a better improvement in group A. Rate of other complications and olfactory function did not show statistically significant differences between the two groups. The average calibration time was approximately 11 min in the A group. Total time of surgical procedure does not evidenced statistically significant difference between the two groups (p > 0.05) but if it is considered only the time of the surgical intervention, the difference of duration is significant reduced statistically (p < 0.05) in CAN surgery.ConclusionComputer assisted navigation in ESS can be useful for the most experienced surgeons, especially in the frontal recess surgery, decreasing the recurrence rate and reducing the total nasal resistance.     

Impact of upper airway abnormalities on the success and adherence to mandibular advancement device treatment in patients with Obstructive Sleep Apnea Syndrome

IntroductionThe mandibular advancement device (MAD) is a option to treat patients with Obstructive Sleep Apnea Syndrome (OSAS).ObjectiveTo assess the influence of upper airway abnormalities on the success of and adherence to MAD in patients with OSAS.MethodsProspective study with 30 patients with mild to moderate OSAS and indications for MAD. The protocol included questionnaires addressing sleep and nasal complaints, polysomnography, and upper airway assessment. The analyzed parameters of patients who showed therapeutic success and failure and those who exhibited good and poor treatment adherence were compared.Results28 patients completed the protocol; 64.3% responded successfully to treatment with MAD, and 60.7% exhibited good adherence to treatment. Factors associated with greater success rates were younger age (p = 0.02), smaller cervical circumference (p = 0.05), and lower AHI at baseline (p = 0.05). There was a predominance of patients without nasal abnormalities among patients treated successfully compared to those with treatment failure (p = 0.04), which was not observed in relation to adherence. Neither pharyngeal nor facial skeletal abnormalities were significantly associated with either therapeutic success or adherence.ConclusionMAD treatment success was significantly lower among patients with nasal abnormalities; however, treatment adherence was not influenced by the presence of upper airway or facial skeletal abnormalities.     

Possible effects of low testosterone levels on olfactory function in males

IntroductionFunctions attributed to androgens have increased, ranging from the role in hypothalamic–pituitary–gonadal axis and reproductive behaviors to modulation of cognition, mood and some other functions. Sex differences and changes in circulating sex hormones affect human sensory function. In the literature, authors reported this kind of influence for olfaction predominantly in females.ObjectiveTo investigate the effects of low testosterone levels on olfactory functions in males, in this prospective clinical study.MethodsMale patients diagnosed with prostate cancer were included. Thirty-nine patients with prostate cancer whose testosterone levels were lower than 50 ng/dL due to castration, were the study group. Thirty-one patients with prostate cancer who were not castrated with testosterone levels higher than 50 ng/dL were selected as the control group. Acoustic rhinometry and peak nasal inspiratory flow tests were performed for all participants; and for evaluation of olfactory function, both groups completed the Connecticut chemosensory clinical research center olfactory test.ResultsThe mean ages of the patients and controls were 69.6 ± 7.2 (57–89) and 66.3 ± 5.8 (50–78) years, respectively (p = 0.039). There was a significant difference between groups in terms of testosterone levels (p < 0.0001). The multivariate logistic regression revealed testosterone level as the only predictive factor determining the difference between the groups. In terms of olfactory parameters, all scores were lower in the emasculated group (butanol threshold test p = 0.019, identification p = 0.059, and Connecticut center score p = 0.029) There was a significant correlation between testosterone levels and olfactory parameters (p = 0.023; p = 0.025 for identification and Connecticut center scores, respectively).ConclusionLow testosterone levels in males have negative effects on olfactory functions. Further molecular research is required to understand the connection between testosterone and olfaction.     

Evaluation of choroidal thickness measurements in patients with marked nasal septal deviation

IntroductionChronic upper airway obstruction due to marked nasal septal deviation may cause chronic hypoxia. It may change the balance of the sympathetic-parasympathetic system and may affect blood flow in the choroid.ObjectiveTo assess choroidal thickness measurements of patients with marked nasal septal deviation.MethodsThe patients who had nasal obstruction symptoms diagnosed with marked nasal septal deviation by anterior rhinoscopy and nasal endoscopy and scheduled for septoplasty were included in the study. The control group consisted of age, sex and body mass index-matched healthy individuals. The choroidal measurements at the central fovea and 1000 μm away from the fovea in the nasal and temporal regions were performed using enhanced depth imaging optical coherence tomography.ResultsIn the study group, 52 eyes of 26 patients with a mean age of 26.34 ± 8.14 years were examined. In the control group, 52 eyes of 28 healthy individuals with a mean age of 26.69 ± 7.84 years were examined. There was no statistically significant difference in terms of choroidal thickness measurements between the groups (p > 0.05).ConclusionOur results suggest that marked nasal septal deviation may not lead to significant hypoxia and sympathetic activation, resulting in deterioration of the choroidal blood flow and consequent choroidal thickening.     

Subtotal supracricoid laryngectomy: changing in indications,surgical techniques and use of new surgical devices

PurposeThe aim of this study is to evaluate the evolution of supracricoid partial laryngectomy (SCPL) in indications, surgical techniques and outcomes through last decades.Materials and methodsA retrospective analysis of 146 patients affected by laryngeal cancer treated with SCPL was carried on. We defined: (1) group A, 100 patients treated by cold instruments between 1995 and 2004; (2) group B, 46 patients treated by harmonic scalpel between 2005 and 2010. Complications rate, and functional and oncological results were documented and a comparison between the two groups was made; histopathological analysis of surgical margins was evaluated and correlated with local incidence of recurrence.ResultsSignificant differences in age mean-value (p = 0.02), T classification (p = 0.007), and in indication for more advanced-staged patients were found in group B (p = 0.001). Surgical procedure was shorter in group B (p < 0.001), with shorter swallowing recovery (p = 0.003). Oncological outcomes did not report any significant differences. Group B showed a higher incidence of post- operative arytenoid edema (p = 0.03) associated with a lower rate of pneumonia (p = 0.038). Despite a higher rate of close or positive-margins found in group B no higher incidence of local-recurrence was reported (p = 0.02) compared to group A.ConclusionsWe documented changing in indications and surgical technique for SCPL because of the development of modern diagnostic techniques and the introduction of low-thermal injury device allowing a more challenging tumor excision as well as with a shorter swallowing recovery in our series.     

Prevalence and characteristics of S-point bleeding compared to non S-point bleeding in severe epistaxis

IntroductionStamm's S-point is gaining importance as a bleeding focus in severe epistaxis. However, prevalence and features of S-point bleeding compared to non S-point bleeding have not been studied.ObjectiveTo investigate the characteristics of patients with S-point bleeding among those with severe epistaxis and to compare the factors involved in the treatment of epistaxis.MethodsWe retrospectively analyzed medical records of 268 patients admitted to the otorhinolaryngology department of Konkuk University Hospital and Chung-Ang University Hospital with epistaxis of which the bleeding focus clarified. Patients with anterior nasal bleeding (n = 129) were excluded. The study was conducted at the department of otorhinolaryngology from January 2008 to August 2019. Collected data included patients’ demographic information, bleeding focus, body mass index underlying medical and sinonasal diseases, laboratory test results (initial hemoglobin, platelet count, and triglyceride level), use of anticoagulants, direction of epistaxis, initial and final treatments, and need for blood transfusion.ResultsThe prevalence of S-point bleeding was 28.8% of non-anterior bleeding cases. Mean body mass index score was lower in the S-point group (23.41 ± 3.71) compared to the non S-point group (24.93 ± 3.97) (p = 0.039). Underweight patients tended to show a greater incidence of S-point bleeding (15.0%) than non S-point bleeding (2.0%) (p = 0.010). Incidence of anemia was higher in the S-point group (67.5%) than in the non S-point group (36.4%). Anemia (Odds ratio [OR]: 3.635; 95% confidence interval [CI]: 1.669-7.914, p = 0.001) and underweight (body mass index < 18.5, OR: 8.559, CI: 1.648-44.445, p = 0.011) were significantly associated with S-point bleeding.ConclusionPrevalence of S-point bleeding was significant, underlining the importance of examining the S-point in patients with severe epistaxis. Patients with S-point bleeding had lower body mass index scores and a higher incidence of anemia than those with non S-point bleeding.     

Pharyngeal motility in patients submitted to type I thyroplasty

IntroductionType 1 thyroplasty is performed to improve glottis closure as well as dysphagic symptoms in patients with unilateral vocal fold immobility.ObjectivesThis study aims to compare the motility of the pharynx and upper esophageal sphincter in patients with unilateral vocal fold immobility before and after thyroplasty Type I.MethodsWe prospectively studied 15 patients with unilateral vocal fold immobility who underwent thyroplasty Type I. Subjects were divided according to the topography of vagal injury and presence of dysphagia. High resolution manometry was performed before and 30 days after surgery. Time and pressure manometric parameters at the topography of the velopharynx, epiglottis and upper esophageal sphincter were recorded.ResultsDysphagia was present in 67% of patients. 63% had lower vagal injuries. Manometric parameters did not change after thyroplasty for the whole population. The group of dysphagic patients, however, had an increase in residual pressure at the upper esophageal sphincter after thyroplasty (1.2 vs. 5.2 mmHg; p = 0.05). Patients with low vagal injury developed higher peak pressure (100 vs. 108.9 mmHg p ≤ 0.001), lower rise time (347 vs. 330 ms p = 0.04), and higher up stroke (260 vs. 266.2 mmHg/ms p = 0.04) at the topography of the velopharynx after thyroplasty.ConclusionPharyngeal motility is affected by thyroplasty Type I in patients with dysphagia and low vagal injury.
