Abstract
Abstract
Study question
The performance and efficiency of the LensHooke® R10 test kit were evaluated by the clinical examination for precision, accuracy, and time.
Summary answer
The LensHooke® R10 based on sperm chromatin dispersion test offers not only quick testing for sperm DNA fragmentation but also reliable and accurate test results.
What is known already
Sperm chromatin dispersion (SCD) test, one of the most commonly used testing for sperm DNA fragmentation (SDF), can be conducted promptly and without the need for expensive laboratory instruments. However, the main disadvantage of the SCD test is inter-observer variability in categorizing the size of characteristics halos surrounding the core of sperm. Moreover, it takes more than one hour to accomplish whole assay procedures making this testing an inefficient diagnostic tool. These may hinder its broad availability among andrology laboratories or prevent it from being routinely used for the evaluation of male infertility.
Study design, size, duration
A total of 108 participants was included in this prospective study. Data was collected from the reproductive medicine center between June and December 2020.
Participants/materials, setting, methods
This study included 108 consecutive male partners of couples attending for assisted reproductive treatment. SDF was simultaneously tested by using LensHooke® R10 (R10) and Halosperm® G2 (G2) respectively. We evaluated the correlation and agreement between two SCD-based test kits. The repeatability and reproducibility of the SCD kits were assessed by intra-and inter-observer agreement experiments. The sensitivity, specificity, positive predictive value, negative predictive value for the R10 was determined by receiver operator characteristics (ROC) curve analysis.
Main results and the role of chance
The R10 produced more clear sperm core and dispersed chromatin, therefore highly recognizable images can be easily and accurately categorized when scoring of SDF. It took 50% less time for SDF testing by the R10 compared to the G2 (38.26 ± 9.85 minutes vs. 76.52 ± 19.7 minutes, P < 0.0001). The SDF% results showed a strong correlation for the R10 and G2 with Spearman’s coefficients of rank correlation (rho) above 0.8 (P < 0.0001, N = 108). The R10 showed 89.8% accuracy with 87.9% sensitivity, 90.8% specificity, 82.9% PPV, and 93.7% NPV on the measurement of SDF% at the threshold value of 22%. Intraclass correlation coefficients (ICC) >0.9 showed a strong agreement between two observers on the testing of SDF using the R10. ICC >0.9 showed a high intra-observer agreement within 4 repeated testing on SDF using the R10. The R10 showed an intra-observer’s precision of coefficient variation, CV < 10% for SDF%. In addition, SDF% test results obtained by the R10 for asthenospermic (31.8% ± 16.7%), teratospermic (22.9% ± 14.4%), and oligoasthenoteratozoospermic samples (36.6% ± 14.4%) were significantly higher than that observed in normozoospermic samples (15.3% ± 10.2%, p < 0.05), was comparable with the G2.
Limitations, reasons for caution
The sample size of 4 semen specimens used to evaluate the intra-and inter-observer agreement was a limitation. Besides, evaluating the relationship between the SDF and clinical outcome of ART is necessary for further study.
Wider implications of the findings: The new in vitro diagnostics reagent, LensHooke® R10, is a simple and quick test kit that offers reliable and accurate test results of sperm DNA fragmentation, can be routinely used in male infertility evaluation.

Abstract
The microbial colonization in the nasopharynx is a prerequisite for the onset of infectious diseases. For successful infection, pathogens should overcome host defenses as well as compete effectively with the resident microbiota. Hence, elucidating the richness and diversity of the microbiome at the site of pathogen colonization is pivotal. Here, we investigated the adenoidal tissue microbiota collected through adenoidectomy to evaluate the impact of Streptococcus pneumoniae. Prospectively, children with sleep-disordered breathing (SDB) and otitis media with effusion (OME) were enrolled. During adenoidectomy, the nasopharyngeal swab and adenoid tissues were collected to determine the pneumococcal carriage and tissue microbiota, using multiplex PCR and 16S ribosomal RNA (16S rRNA) pyrosequencing. A total of 66 pediatric patients comprising 38 children with SDB and 28 children with OME were enrolled. There was no difference between the bacterial cultures from the surface of the nasopharyngeal adenoid in the SDB and OME groups. Thirty-four samples (17 SDB and 17 OME) underwent 16S rRNA pyrosequencing and fulfilled the criteria for further analysis. The Shannon diversity index for the samples from the SDB patients was found to be higher than that observed for the samples from OME patients, although the difference was not significant (p = 0.095). The Shannon diversity index for the samples negative for the pneumococcal carriage was significantly higher than that for the samples positive for pneumococcal carriage (p = 0.038). Alloprevotella, Staphylococcus, Moraxella, and Neisseriaceae were significantly dominant in the samples positive for the pneumococcal carriage. Dialister was significantly less present in the adenoid tissue positive for the pneumococcal carriage. Streptococcus pneumoniae, one of the most common pathogens of the airway, significantly influences the composition and diversity of the microbiota in the nasopharyngeal adenoid. Thus, bacterial community analysis based on 16S rRNA pyrosequencing allows for better understanding of the relationship between the adenoidal microbial communities.

Abstract
Introduction Most patients with asthma, either allergic or non-allergic, usually exhibit some level of concurrent rhinitis. Treatments for rhinitis and asthma can affect both conditions. Objective The present study aimed to examine asthma-specific outcomes in patients with chronic rhinitis (CR) and asthma after surgery for nasal obstruction, and to identify the patient group most likely to experience improved asthma control after surgery. Methods Asthmatic patients with CR and nasal obstruction were prospectively recruited for evaluations of nasal and asthma-specific outcomes before and after surgery for nasal obstruction. Results Twenty-eight participants were enrolled. There was a significant association between the Asthma Control Test (ACT) and the Sino-Nasal Outcome Test-22 scores, both at the preoperative and 3-month postoperative assessments. Patients demonstrating ACT improvement after nasal surgery had worse preoperative ACT scores and predicted forced expiratory volume in 1 s. Conclusion Nasal symptom severity was closely associated with the extent of asthma control in asthmatic patients with CR and nasal obstruction. Assessment of CR and nasal obstruction in patients with poorly controlled asthma should be considered an essential approach to improve the response to treatment and patients’ quality of life.

Abstract
OBJECTIVES /HYPOTHESIS Empty nose syndrome (ENS) is a complicated condition currently thought to be caused by excessive surgical resection of turbinate tissue. Patients with ENS experienced significant psychological symptoms, such as depression and anxiety. This study aimed to evaluate the impact of the psychological burden on the surgical outcome of ENS. STUDY DESIGN Prospective case series in a tertiary medical center. METHODS Patients with ENS were prospectively recruited between 2015 and 2018. Validated instruments including the Sinonasal Outcome Test-25 (SNOT-25), Beck Depression Inventory-II (BDI-II), and Beck Anxiety Inventory (BAI) were used to evaluate patients with ENS prior to and 3, 6, and 12 months after nasal reconstruction surgery with submucosal Medpor implantation. RESULTS A total of 54 ENS patients were enrolled during the study period. All three evaluations revealed significant improvement, and symptoms stabilized 3 months after surgery. Six months post-operatively, SNOT-25 scores were significantly associated with the pre-operative BDI-II and BAI scores (β = 0.64 and 0.87; P = .006 and <.001, respectively). Multivariate regression model revealed that only BAI scores were significantly associated with the six-month post-operative SNOT-25 scores (adjusted β = 0.49, P = .036). Moreover, Spearman's correlation found close relationships between the post-operative SNOT-25 and the post-operative BDI-II and BAI scores (rs = 0.751 and 0.884, both P < .001). CONCLUSIONS Psychological evaluation can help predict surgical outcomes and identify patients with residual disease. These findings emphasize the importance of screening for psychological symptoms and structuring care by including psychological therapy in addition to surgery. LEVEL OF EVIDENCE 4.

Abstract
With the broad indications for dental implantation, complications rates have increased. Dental implant displacement into the maxillary sinus, although rare, can occur during the restoration of maxillary posterior teeth. We performed a 6-year retrospective review and found 3 cases with displaced implants in the maxillary sinus. Detailed information, including surgical indications and dental implant removal methods, is provided. Dental implants can be dislocated to the maxillary sinus perioperatively or postoperatively. Endoscopic sinus surgery can be performed to remove the implant and restore sinus patency. If the implant is displaced to deeper areas (commonly anterior and inferior) of the maxillary sinus, a prelacrimal recess approach can provide a panoramic view of the maxillary sinus and is a good alternative to the Caldwell-Luc operation in terms of mucosal preservation and postoperative complications.

Abstract
Abstract
Background
Rivaroxaban is useful for stroke prevention in atrial fibrillation (AF) patients. Most patients with non-permanent AF also treated with anti-arrhythmic drugs (AADs) to prevent the recurrence of arrhythmia. But there are limited data regarding drug-drug interactions between rivaroxaban and AADs despite its high clinical relevance.
Purpose
To compare the bleeding risks and ischemic events between the use of rivaroxaban alone and the concomitant use of AADs.
Methods
This is a multicenter retrospective study, which identified patients with a diagnosis of non-permanent AF who received rivaroxaban more than 1 month between December 1, 2011 and November 30, 2016. The study divided patients into 4 groups : rivaroxaban alone, combined with amiodarone, dronedarone and propafenone. We compared the clinical events and cumulative incidences to compare the endpoints including efficacy endpoint (new ischemic stroke, intracranial hemorrhage, or new
embolism), safety endpoints (Hb fall more than 2g/dL or transfusion more than 2U PRBC, critical site bleeding, or fatal bleeding.) and major adverse cardiovascular events (MACE), including cardiovascular death, myocardial infarction, new ischemic stroke, new embolism, or intracranial hemorrhage.
Results
Of 1777 enrolled patients, the rivaroxaban alone was 1205 cases, 177 in amiodarone group, 231 in dronedarone group and 164 in propafenone group. There was no statistically significant difference on efficacy endpoints, safety endpoints and MACE between the 4 groups. The average dosage of rivaroxaban was insignificantly the lowest in the group combined with dronedarone (12.3mg, p = 0.146). The rate of new embolism (0%, p = 0.029), recurrent heart failure admission rate (3.9%, p < 0.001), and all-cause mortality (3.0%, p = 0.013) in dronedarone group showed a significant lower occurrence rate. The occurrence rate of new ischemic stroke (0.9%, p = 0.549), new hemorrhagic stroke (0.4%, p = 0.546), efficacy endpoints (1.7%, p = 0.369) and MACE (3.9%, p = 0.72) in dronedarone droup were the lowest but insignificant. The cumulative incidences of efficacy endpoints, safety endpoints and MACE during follow-up period were also similar in these four groups.(Picture 1)
Conclusions
In patients with non-permanent atrial fibrillation, this real-world study showed that there were no significant differences between using rivaroxaban alone or concomitant with an AAD (dronedarone/amiodarone/propafenone) on events such as new ischemic stroke, intracranial hemorrhage, GI bleeding and MACEs. The happening of new embolism was lower especially in the group combined with dronedarone. The safety and efficacy between rivaroxaban alone and combined with rhythm control using AADs proved to be the same. Relative low dose rivaroxaban combined with dronedarone did not increase the bleeding risk, and may decrease the probability of thromboembolism.

Abstract
Abstract
Background
Novel oral anticoagulants (NOAC) is important in preventing thromboembolism in atrial fibrillation (AF) patients. Bleeding risk was evaluated by HAS-BLED score traditionally. Data mining is a relatively new discipline that has sprung up at the confluence of several other disciplines, driven primarily by the growth of large databases.
Purpose
This study aimed to find a useful predictive model by data mining to assess the risk of rivaroxaban, an antithrombotic drug that causes bleeding in AF patients. The seven parameters of the HAS-BLED score were used to predict the effect of rivaroxaban on bleeding tendency in AF patients and may provide clinicians with appropriate treatments to avoid complications from bleeding events and reduce the incidence of health damage.
Methods
Through conducting a multicenter retrospective study, we identified patients with AF who were treated with rivaroxaban for more than 1 month between December 1, 2011 and November 30, 2016. After preprocessing, the established data were used for training and testing of data mining models. This study evaluated four models, including association rules, neural networks, Bayesian classification, and decision trees.
Result
Of the 872 enrolled cases, 432 were in any of the bleeding groups and 432 were in the non-bleeding randomized control group. After comparing the overall classification accuracy, omission error and over-prediction error, the decision tree proved to be the most accurate model for bleeding prediction. The overall classification accuracy is 77%, the omission error is 15%, the over-prediction error is 21.9%, and the AUC score is 0.84. The results show that the model has good discriminative ability and visibility of decision rules.
Conclusion
Among several data mining models, decision tree proved to be the most accurate model for bleeding prediction. The conclusion of this study can be used as a reference for supporting decision making before anticoagulation treatment and suggest future research to compare efficacy of bleeding prediction between HAS-BLED score and decision tree.

Abstract
A potential mechanism underlying cigarette smoke-induced airway disease is insufficient tissue repair via altered production of matrix metalloproteinases (MMPs). Osteitis is a signature feature of recalcitrant chronic rhinosinusitis (CRS) and often results in revision surgery. The present study aimed to investigate MMP expression in the nasal tissues of asthmatic patients with CRS and any association with cigarette smoking and osteitis. Thirteen smokers with CRS and asthma, 16 non-smokers with CRS and asthma, and seven non-smoker asthmatic patients without CRS were prospectively recruited. The expression of MMPs and associated immunological factors in surgically-obtained nasal tissues was evaluated via real-time PCR and western blotting. Maximal bone thickness of the anterior ethmoid (AE) partition was measured in axial sinus computed tomography (CT) sections. MMP-1 and MMP-9 expression was increased in the nasal tissues of smokers with asthma and CRS via real-time PCR and western blot. Maximal AE partition bone thickness was greater in smokers with CRS and asthma than in non-smokers with CRS and asthma. MMP-1 and MMP-9 levels were correlated with maximal AE bone thickness. Cigarette smoking was associated with the up-regulation of MMP-1 and MMP-9 in the nasal tissues of patients with airway inflammatory diseases, and with AE osteitis, and with therapeutic resistence.

Abstract
OBJECTIVES In the past two decades, endoscopic sinus surgery (ESS) has been performed frequently in children with medically recalcitrant chronic rhinosinusitis (CRS). However, surgical success rates vary according to age. The causes of failure and prognostic factors for revision ESS remain unclear. The aims of the present study were to evaluate prognostic factors related to revision surgery after ESS, and to determine the most optimal timing for surgery in the pediatric population. METHODS This was a retrospective review in a tertiary medical center. Children who underwent ESS for CRS between 2004 and 2017 were enrolled. Demographics, sinonasal examination findings, previous operation history, laboratory data, comorbidities, and computed tomography (CT) results were collected from medical records. Prognostic factors for revision surgery were analyzed. RESULTS A total of 188 pediatric patients were enrolled in this study. Twenty-four patients (12.8%) required revision surgery. Multivariate logistic regression analysis identified patients with nasal allergy (OR = 6.258; P = .010) and higher Lund-Mackay score on preoperative sinus CT (OR = 1.658; P = .043) had worse outcomes, while older age was a positive prognostic factor (OR = 0.702; P = .018). A cut-off point of 15.68 years of age and mean Lund-Mackay score of 10.5 showed the best predictive power for revision surgery. CONCLUSION Because ESS is performed with increasing frequency in children, knowledge of prognostic factors for revision surgery is important. In this study, patients with younger age, nasal allergy, and higher Lund-Mackay score on preoperative sinus CT had worse outcomes. LEVEL OF EVIDENCE 4 Laryngoscope, 130:1051-1055, 2020.

Abstract
Background: Cigarette smoke have adverse effects in the control of asthma and chronic rhinosinusitis (CRS). Interleukin (IL)-17A, the signature cytokine of helper T 17 cells and group 3 innate lymphoid cells (ILC3), has been reported to link with resistance to therapy in airway inflammation. This study aimed to investigate the impact of cigarette smoking and IL-17A activation on the clinical outcomes of asthmatic patients with chronic rhinosinusitis.
Methods: 33 patients with CRS and asthma, including 15 smokers and 18 non-smokers, and 7 asthmatic patients without CRS and smoking were prospectively recruited. The Sino-Nasal Outcome Test-22 and Asthma Control Test were used to evaluate sinonasal symptoms and the level of asthma control, respectively. Real-time PCR and immunostaining were applied to evaluate the expression levels of IL-17A and associated immunological factors on surgically-obtained nasal tissues.
Results: Nasal surgery improved both sinonasal symptoms and asthma control. Compared to non-smokers, smokers showed poorer improvement in asthma control. The expression of IL-17A, IL-22, aryl hydrocarbon receptor (AhR), and ILC3 was increased in the nasal tissues of smokers with asthma and CRS. The expression of IL-17A mRNA was correlated with that of AhR and with positive nuclear AhR-AhR nuclear translocator staining cells, and that of cyclooxygenase-2 enzyme (COX-2). ILC3 cells were associated with IL-17A, IL-22, AhR, and COX-2 mRNA expression.
Conclusions: Cigarette smoking was related to lesser improvement in asthma control after nasal surgery and to IL-17A activation in the nasal tissues of patients with inflammatory airways.

Abstract
OBJECTIVES/HYPOTHESIS Maxillary sinus fungus ball (MSFB) is the most common type of noninvasive fungal rhinosinusitis. Surgical removal of the ball achieves good outcomes. Making a rapid and accurate diagnosis is important to avoid unnecessary medical therapy. Intralesional hyperdensity (IH) on computed tomography (CT) is reportedly a good indicator. The aim of this study was to evaluate the diagnostic features of MSFB without IH on preoperative CT images. STUDY DESIGN Retrospective database review. METHODS Two hundred fifty-eight patients with histopathological evidence of a sinus fungal ball were retrospectively investigated. Forty-seven of 222 patients with MSFB did not show IH on preoperative CT images and were enrolled in the MSFB group. Forty-one patients with unilateral nonfungal chronic rhinosinusitis were enrolled in a control group. CT features previously reported to have diagnostic significance were evaluated. RESULTS Sclerosis of the lateral sinus wall, erosion of the inner sinus wall, and irregular surface of the material were significantly more common in the MSFB group than in the control group. In the subgroup of patients with total opacification in the maxillary sinus, the sensitivity, specificity, and positive and negative predictive values for erosion of the inner sinus wall were more than 90%. In the subgroup with partial opacification, the sensitivity, specificity, and positive predictive value of an irregular surface of the material were more than 80%. CONCLUSIONS We have devised an algorithm to help diagnose MSFB without IH on preoperative CT images. Use of this algorithm would improve the diagnostic accuracy and ensure appropriate treatment.

Abstract
Tonsil and adenoid-tissue hypertrophy (AH) is the most common cause of pediatric sleep-disordered breathing (SDB), with AH possibly initiated by repeated exposure to infectious agents or allergens. Here, we evaluated IL-17A activity in adenoid tissue from children with SDB and its association with AH and pneumococcal carriage. Thirty-five children (aged 3-12 years) with SDB and receiving adenoidectomy and tonsillectomy were enrolled. During surgery, nasopharyngeal carriage was determined by bacterial culture and multiplex PCR via nasopharyngeal swab, and adenoid samples were collected. IL-17A and associated cytokine expression was evaluated by real-time PCR and western blotting. The mRNA analysis showed that IL-17A level, IL-17A:IL-10 ratio, and RAR-related orphan receptor-γt:forkhead box P3 ratio were significantly higher in adenoid tissues with AH, as were IL-17A level and IL-17A:IL-10 ratio in adenoid tissues with pneumococcal carriage. Additionally, pneumococcal carriage was more common in nasopharyngeal adenoids from patients without AH than those with AH. IL-17A was upregulated in adenoid tissues from patients with AH and with pneumococcal carriage. These results suggested that pneumococcal carriage initiates an IL-17A-mediated immune response in nasopharyngeal adenoids, which might be associated with AH in patients with SDB.

Abstract
OBJECTIVE We sought to develop a model to calculate the likelihood of vaginal delivery in nulliparous women undergoing induction at term. STUDY DESIGN We obtained data from the Consortium on Safe Labor by including nulliparous women with term singleton pregnancies undergoing induction of labor at term. Women with contraindications for vaginal delivery were excluded. A stepwise logistic regression analysis was used to identify the predictors associated with vaginal delivery by considering maternal characteristics and comorbidities and fetal conditions. The receiver operating characteristic curve, with an area under the curve (AUC) was used to assess the accuracy of the model. RESULTS Of 10,591 nulliparous women who underwent induction of labor, 8,202 (77.4%) women had vaginal delivery. Our model identified maternal age, gestational age at delivery, race, maternal height, prepregnancy weight, gestational weight gain, cervical exam on admission (dilation, effacement, and station), chronic hypertension, gestational diabetes, pregestational diabetes, and abruption as significant predictors for successful vaginal delivery. The overall predictive ability of the final model, as measured by the AUC was 0.759 (95% confidence interval, 0.749-0.770). CONCLUSION We identified independent risk factors that can be used to predict vaginal delivery among nulliparas undergoing induction at term. Our predictor provides women with additional information when considering induction.

Abstract
Monolayers of transition metal dichalcogenides (TMD) are promising materials for optoelectronics devices. However, one of the challenges is to fabricate large-scale growth of high quality TMD monolayers with the desired properties in order to expand their use in potential applications. Here, we demonstrate large-scale tungsten disulfide (WS2) monolayers grown by van der Waals Epitaxy (VdWE). We show that, in addition to the large structural uniformity and homogeneity of these samples, their optical properties are very sensitive to laser irradiation. We observe a time instability in the photoluminescence (PL) emission at low temperatures in the scale of seconds to minutes. Interestingly, this change of the PL spectra with time, which is due to laser induced carrier doping, is employed to successfully distinguish the emission of two negatively charged bright excitons. Furthermore, we also detect blinking sharp bound exciton emissions which are usually attractive for single photon sources. Our findings contribute to a deeper understanding of this complex carrier dynamics induced by laser irradiation which is very important for future optoelectronic devices based on large scale TMD monolayers.

Abstract
PURPOSE Acute otitis media (AOM) is a common infectious disease in children and usually accompanied by a preceding viral respiratory tract infection, especially in the preschool-age population. The study aimed to evaluate impact of influenza vaccine on childhood otitis media. METHODS This retrospective cohort study included data for 803,592 children (<10 years old) recorded in Taiwan's National Health Insurance Research Database. AOM incidence and tympanostomy tube insertion incidence in each influenza season before and after the introduction of traditional injectable trivalent influenza vaccine (TIV) were compared using the Poisson regression analysis to estimate the incidence rate ratios (IRRs) and 95% confidence intervals (CIs). RESULTS In children < 2 years old, the age group eligible for free influenza vaccination, there was a significant reduction in seasonal AOM incidence after TIV introduction in 2004 (from 98.4 episodes/1000 person-seasons [95% CI: 96.4-100.5] to 66.1 episodes/1000 person-seasons [95% CI: 64-68.1]). In addition, with the increased vaccine coverage rate, the outpatient visits for AOM in the influenza season of 2005 and 2006 were significantly lower than that in 2004 (IRR = 0.85 and 0.80, respectively, p < 0.0001). CONCLUSIONS A significant reduction in primary care consultations for children <2 years old was observed after the introduction of the TIV in Taiwan in 2004. With the increased vaccine coverage, there was an additional decline in 2005 and 2006. In addition of the direct protection provided by the vaccination, we believe that TIV may have induced some herd immunity that further contributed to the reduction in influenza attack rates and the rates of associated AOM in that age group. These reductions were observed only in vaccine-eligible children, while older children, who were not enrolled in the influenza vaccination program during the study period, have experienced increases in the AOM incidence during the 2004-2006 period compared to the 2000-2003 period.

Abstract
RATIONALE Schwannomas are solitary neurogenic tumors that arise from cells of the neural sheath. Ancient schwannoma is a relatively rare variant of schwannoma, characterized by increased cellularity and atypia. These cellular changes could be confusing and make the accurate pathologic diagnosis difficult. PATIENT CONCERNS AND DIAGNOSES A 36-year-old man presented with painless swelling in left submandibular region for more than 2 years. The computed tomography confirmed a well-defined cystic lesion in the left submandibular space, which caused superior and posterior displacement of the left submandibular gland. Surgical excision was performed and the pathology confirmed the diagnosis of ancient schwannoma. To our knowledge, this patient is the second case of primary submandibular ancient schwannoma reported in the literatures. INTERVENTIONS AND OUTCOMES The patient underwent tumor resection and postoperative recovery was uneventful. There were no nerve deficits after the operation. There was no recurrence within 1 year of follow-up. LESSONS Schwannoma originated from the submandibular gland is extremely rare and only a few cases have been reported. Ancient schwannoma is an even more rare tumor. The increased cellularity and atypia of ancient schwannoma can resemble features of malignancy. Great care must be taken to make differential diagnosis with fibrosarcomas and malignant schwannoma.

Abstract
OBJECTIVES To determine a paradigm for evaluating and managing maxillary sinus conditions before dental implantation via preoperative sinonasal assessment. STUDY DESIGN Prospective cohort study. METHODS Eighty-four patients who underwent dental implantation with or without sinus augmentation were included. Maxillary sinus conditions were classified into groups 1 to 6 according to cone-beam computed tomography (CT) findings: 1) nonspecific findings, 2) solitary polyp or cyst, 3) mucosal thickening, 4) air-fluid level or fluid accumulation, 5) near-total opacification of the maxillary or other paranasal sinus, and 6) calcification spots in the maxillary sinus. Dental implantation with or without sinus augmentation was suggested with postoperative sinus observation (groups 1-3), after medication for acute sinusitis (group 4), and after comprehensive treatment of chronic or fungal sinusitis (groups 5-6). Intraoperative and postoperative sinus-related complications were recorded. RESULTS Two patients (groups 1 and 3) developed acute rhinosinusitis after sinus augmentation; both recovered completely with medical treatment. Schneiderian membrane perforation occurred during sinus lift surgery in six patients (group 1): five recovered after conservative medical therapy and close observation, whereas one required endoscopic sinus surgery and recovered well. No chronic rhinosinusitis developed after dental implantation. CONCLUSION Craniofacial CT is crucial for pre-dental implantation sinonasal evaluation. The risk of dental implant-related chronic rhinosinusitis is low for patients with cysts, polyps, or mucosal thickening in the maxillary sinus. However, preventive endoscopic sinus surgery is recommended for patients with incurable chronic rhinosinusitis, fungal sinusitis, and large polyps or cysts. LEVEL OF EVIDENCE 4.

Abstract
BACKGROUND Empty nose syndrome (ENS) describes symptomatology and radiographic findings after surgeries on turbinates.The treatment of ENS is still debatable. PURPOSE To analyse clinical outcomes of submucosal Medpor® implantation for ENS. METHODS A total of 18 patients underwent submucosal Medpor® implantation from 2006 to 2011. We applied SNOT-22 (SinoNasalOutcome Test) for statistical survey of the patients' symptoms before and after surgery. RESULTS Two patients were lost to follow up after the surgery. Most of the patients developed ENS-related symptoms gradually within 2 years to 16 years after the previous nasal surgery or treatment. The sites of submucosal implantation are mainly septum and nasal floor, unilaterally or bilaterally. There is a significant improvement of SNOT-22 pre-operatively to one year post-operatively. CONCLUSIONS The symptomatolgy remains the most important point when dealing with patients with ENS. Submucosal implantation of Medpor® is a feasible surgical treatment to ENS. A positive cotton test is suggested for the surgical indication and planning.

Abstract
RATIONALE Plasma cell neoplasms are categorized by neoplastic proliferation of a single clone of plasma cells which produce a monoclonal immunoglobulin. Plasma cell neoplasms can present as a solitary plasmacytoma or as multiple myeloma. Both of them can progress to multiple myeloma. Once a diagnosis of plasmacytoma has been made, thorough examinations should be carried out for identifying the disease entity. PATIENT CONCERNS AND DIAGNOSES Herein, we describe an extraordinary rare case of multiple myeloma with initial presentation of a left sphenoid neoplasm resulting in left-sided headache and rapid deterioration of visual acuity. Histo-pathologic analysis revealed a plasma cell neoplasm with positive immunostaining for cluster of differentiation (CD)138, CD79a, and kappa light chain of immunoglobulin. A bone marrow aspiration was then performed, and the diagnosis of multiple myeloma was then confirmed. INTERVENTIONS AND OUTCOMES After investigative workup, our patient received chemotherapy, localized radiotherapy, and autologous stem cell transplantation. Her visual acuity recovered to the baseline and she sustained a partial response without subjective discomfort. LESSONS Extramedullary plasmacytoma is an interesting but infrequent presentation of multiple myeloma. Moreover, involvement of the sphenoid sinus in multiple myeloma resulting in extrinsic optic nerve compression is extremely rare. Clinicians should consider plasmacytoma as a diagnostic possibility when presented with cases of solitary sphenoid neoplasm and rapid progression of clinical course.

Abstract
Coexistence of chronic rhinosinusitis (CRS) with asthma appears to impair asthma control. Type-2 innate lymphoid cells (ILC2s) respond to the cytokines of thymic stromal lymphopoietin (TSLP), interleukin (IL)-25 and IL-33, thus contributing to airway diseases such as CRS and asthma. We investigate whether the augmented Th2-cytokines in CRS might be related to sinonasal tract ILC2s corresponding to enhanced IL-25, IL-33 and TSLP release in severe asthmatics, and be involved in asthma control. Twenty-eight asthmatics (12 non-severe and 16 severe) with CRS receiving nasal surgery were enrolled. The predicted FEV1 inversely associated with CRS severity of CT or endoscopy scores. Higher expression of Th2-driven cytokines (IL-4, IL-5, IL-9, and IL-13), TSLP, IL-25 and IL-33 in nasal tissues was observed in severe asthma. Severe asthmatics had higher ILC2 cell counts in their nasal tissues. ILC2 counts were positively correlated with Th2-cytokines. Nasal surgery significantly improved asthma control and lung function decline in severe asthma and CRS. The higher expression of IL-33/ILC2 axis-directed type 2 immune responses in nasal tissue of CRS brought the greater decline of lung function in severe asthma. ILC2-induced the upregulated activity of Th2-related cytokines in asthmatics with CRS may contribute to a recalcitrant status of asthma control.

Abstract
Levels of hydrogen sulfide (H2S), a gaseous signaling molecule, are reduced in the serum of individuals who smoke. We hypothesized that tobacco smoke influenced smooth muscle relaxation by decreasing H2S levels and this effect could also influence expression of cystathionine γ-lyase (CSE) and sulfonylurea receptor-2 (SUR-2). The aim of this study was to explore the effect of tobacco smoke on H2S-mediated rat thoracic aorta relaxation and its possible mechanism. Thirty-two Sprague-Dawley rats were divided into four groups: control (C) group, short-term smoker (SS) group, mid-term smoker (MS) group, and long-term smoker (LS) group. H2S concentrations in serum, action of H2S on rat aortic vascular relaxation, and expression of CSE and SUR-2 in thoracic aortic smooth muscle were measured. Although there was no significant difference in H2S between the C and the SS groups, concentration of H2S was significantly reduced in both the LS and MS groups compared to control (P<0.01). Furthermore, H2S was significantly lower in the LS than in the MS group (P<0.05). Rat aortic vascular relaxation was lower in all three treatment groups compared to the control, with the most significant decrease observed in the LS group (P<0.05 compared to the MS group). Expression of CSE and SUR-2 was reduced in the LS and MS groups compared to control (P<0.05), with the lowest levels observed in the LS group (P<0.05). Therefore, tobacco smoke reduced expression of CSE and SUR-2 in rat thoracic aorta, which may inhibit H2S production and vascular dilation.

Abstract
The united airways concept suggests that patients with asthma typically exhibit parallel inflammation in the upper airway. The resulting nasal symptoms should reduce quality of life and substantially affect the evaluation of asthma control among these patients. This study aimed to assess the association of nasal symptoms with the evaluation of asthma control.Fifty-eight patients with asthma and persistent nasal symptoms were prospectively recruited for evaluations of their sinonasal symptoms and asthma control in a cross-sectional study from August 2013 to June 2016. Participants underwent thorough nasal endoscopy, sinus computed tomography, pulmonary function testing, the asthma control test (ACT), and the Sino-Nasal Outcome Test-22 (SNOT-22) questionnaires to evaluate their asthma control and sinonasal symptoms.There was a significant association between ACT and SNOT-22 scores. Among patients with asthma and chronic rhinosinusitis, ACT scores were closely related to the symptoms of cough, post-nasal discharge, dizziness, waking up at night, absence of a good night's sleep, and waking up tired. Among patients with asthma and chronic rhinitis, the forced expiratory volume in 1 second was closely related to the symptoms of needing to blow nose, runny nose, and cough. Patients with emergency clinic visits during the previous 3 months had relatively high SNOT-22 scores, especially for the symptoms of sneezing, runny nose, nasal blockage, cough, and dizziness.Sinonasal symptom severity was closely associated with measured asthma control status among patients with asthma and persistent nasal symptoms. Therefore, upper and lower airway inflammations should be considered and treated simultaneously.

Abstract
Cigarette smoke plays a substantial role in the development of airway inflammatory diseases, including asthma and chronic rhinosinusitis (CRS). Interleukin (IL)-17A might contribute to cigarette smoke-related inflammation of the airway. This study aimed to investigate the association between cigarette smoking and IL-17A expression in the nasal tissues of patients with CRS and asthma.We prospectively recruited 24 patients (13 smokers, 11 nonsmokers) with CRS and asthma and 6 patients with asthma but without CRS (control group) in a tertiary medical center. Nasal mucosa was obtained as part of the nasal surgery. Protein and mRNA levels of IL-17A in the nasal tissues were determined by immunostaining and real-time polymerase chain reaction.The number of unexpected emergency clinic visits for acute asthma attacks were higher among smokers than among nonsmokers. Interleukin-17A protein and mRNA levels in the nasal tissues of smokers were greater compared to those in the nasal tissues of nonsmokers (P = 0.02 both) and control patients (P = 0.05 and 0.04, respectively).Cigarette smoking was associated with an increase in the number of unexpected emergency clinic visits due to acute asthma attack and in the expression of IL-17A in the nasal tissues of patients with airway inflammatory diseases.

Abstract
Treatments for chronic rhinosinusitis (CRS) and asthma can affect both conditions, based on the united airway concept. This study aimed to evaluate the link between CRS and asthma, based on disease-specific quality of life measures.We performed a prospective cohort study to investigate the correlations between results from CRS- and asthma-specific questionnaires. Thirty-two patients with asthma and CRS were evaluated before and after undergoing nasal surgery at a tertiary medical center.There were significant correlations between the results from the Asthma Control Test (ACT) and the Sino-Nasal Outcome Test-22, as well as between the results of the ACT and Rhinoconjunctivitis Quality of Life Questionnaire, at both the preoperative and 3-month postoperative evaluations (P < 0.01). Moreover, nasal surgery improved the sinonasal symptoms, asthma control, and pulmonary function (P < 0.01).Increasingly severe sinonasal symptoms of CRS were associated with poor asthma control. Therefore, CRS and asthma should be considered and treated as common airway diseases.
