Abstract
BACKGROUND Airway obstruction caused by viscous mucus is an important pathophysiologic characteristic of persistent inflammation, which can result in organ damage. OBJECTIVE We investigated the hypothesis that the biophysical characteristics of accumulating granulocytes affect the clinical properties of mucus. METHODS Surgically acquired nasal mucus samples from patients with eosinophilic chronic rhinosinusitis and neutrophil-dominant, noneosinophilic chronic rhinosinusitis were evaluated in terms of computed tomography density, viscosity, water content, wettability, and protein composition. Isolated human eosinophils and neutrophils were stimulated to induce the formation of extracellular traps, followed by the formation of aggregates. The biophysical properties of the aggregated cells were also examined. RESULTS Mucus from patients with eosinophilic chronic rhinosinusitis had significantly higher computed tomography density, viscosity, dry weight, and hydrophobicity compared to mucus from patients with noneosinophilic chronic rhinosinusitis. The levels of eosinophil-specific proteins in mucus correlated with its physical properties. Eosinophil and neutrophil aggregates showed physical and pathologic characteristics resembling those of mucus. Cotreatment with deoxyribonuclease and heparin, which slenderizes the structure of eosinophil extracellular traps, efficiently induced reductions in the viscosity and hydrophobicity of both eosinophil aggregates and eosinophilic mucus. CONCLUSIONS The present study elucidated the pathogenesis of mucus stasis in infiltrated granulocyte aggregates from a novel perspective. These findings may contribute to the development of treatment strategies for eosinophilic airway diseases.

Abstract
In the last decade, it has become evident that various RNA viruses infect helminths including Order Ascaridida. However, there is still no information available for viruses infecting Anisakis. We herewith demonstrate the presence of a novel rhabdovirus from Anisakis larvae detected by next-generation sequencing analysis and following RT-PCR. We determined the nearly all nucleotide sequence (12,376 nucleotides) of the viral genome composed of seven open reading frames, and we designated the virus as Suzukana rhabdo-like virus (SkRV). BLASTx search indicated that SkRV is a novel virus belonging to the subfamily Betanemrhavirus, rhabdovirus infecting parasitic nematodes of the Order Ascaridida. SkRV sequence was detectable only in the total RNA but not in the genomic DNA of Anisakis, ruling out the possibility of SkRV being an endogenous viral element incorporated into the host genomic DNA. When we individually tested Anisakis larvae obtained from Scomber japonicus migrating in the coastal waters of Japan, not all but around 40% were SkRV-positive. In the phylogenetic trees of Betanemrhavirus and of the host Ascaridida nematodes, we observed that evolutional distances of viruses were, to some extent, parallel with that of host nematodes, suggesting that viral evolution could have been correlated with evolution of the host. Although biological significance of SkRV on Anisakis larvae is still remained unknown, it is interesting if SkRV were somehow related to the pathogenesis of anisakiasis, because it is important matter of public health in Japan and European countries consuming raw marine fishes.

Abstract
Parotid tumors present a wide range of histological features, from benign to malignant. Periostin, an extracellular matrix protein specifically expressed in the periosteum and periodontal ligament, is isolated from osteoblast cell lines. It regulates fibrosis and collagen deposition and plays an important role in myocardial repair after myocardial infarction. It is also known to be involved in otorhinolaryngological-diseases. This study included 36 patients [38 specimens; 16 men and 20 women, mean age 59.2 (range 26-82) years] who underwent parotid tumor resection at the Division of Otorhinolaryngology, Tohoku Medical and Pharmaceutical University, between April 2017 and March 2022 and were clinically and pathologically diagnosed as having benign parotid tumors. Formalin-fixed, paraffin-embedded sections from the surgical specimens were autoclaved and immunostained with anti-periostin antibodies to evaluate the expression and distribution of periostin. Histologically, the tumors were diagnosed as pleomorphic adenomas in 15 cases (15 specimens), Warthin's tumors in 13 cases (15 specimens), basal cell adenomas in 2 cases (2 specimens), oncocytomas in 4 cases (4 specimens), and myoepitheliomas in 2 cases (2 specimens). An increased expression of periostin was found in 32 of 38 samples (84.2%) in the stroma of benign parotid tumors. Four distinct patterns of periostin expression were observed in benign parotid gland tumors: negative, superficial, infiltrative, and diffuse. Statistically significant differences were found between periostin expression patterns and histological classification of the tumors. Our results suggest that periostin may be involved in the pathogenesis of benign parotid tumors and could serve as a new biomarker for these tumors.

Abstract
BACKGROUND The daytime tiredness experienced by the vast majority of allergic rhinitis (AR) sufferers is directly related to the fact that they experience disrupted sleep at night. This study compared the effects of recently marketed second-generation H1 antihistamines (SGAs) on nighttime sleep and daytime sleepiness in patients with AR, with patients grouped into those taking non-brain-penetrating antihistamines (NBP group) and those taking brain-penetrating antihistamines (BP group). METHODS Patients with AR completed self-administered questionnaire-based surveys to determine Pittsburgh Sleep Quality Index (PSQI) before and after taking SGAs. Statistical analysis was performed on each evaluation item. RESULTS Of 53 Japanese patients with AR between 6 and 78 years old, median (SD) age was 37.0 (22.4) years old and 21 were men (40%). Of the 53 patients, 34 were the NBP group and 19 were the BP group. In the NBP group, mean (SD) subjective sleep quality score after medication was 0.76 (0.50), which was significantly lower (better) than the score of 0.97 (0.52) before medication (p = 0.020). In the BP group, mean (SD) subjective sleep quality score after medication was 0.79 (0.54), which was not significantly different from the score of 0.74 (0.56) before medication (p = 0.564). In the NBP group, mean (SD) global PSQI score was 3.47 (1.71) after medication, which was significantly lower (better) than the score of 4.35 (1.92) before medication (p = 0.011). In the BP group, mean (SD) global PSQI score was 2.47 (2.39) after medication, which was not significantly different from the score of 3.00 (2.71) before medication (p = 0.125). CONCLUSION Subjective sleep quality and global PSQI score were improved only in the group taking non-brain-penetrating SGAs.

Abstract
OBJECTIVE Functional hearing loss (FHL) is a disorder in which there are abnormal values on a hearing test, despite the absence of organic abnormalities in the peripheral and central auditory pathways. Here, we examined the developmental characteristics of FHL and the importance of intervention by analyzing the clinical characteristics of children with this disorder. METHODS We retrospectively examined 16 patients assessed under a diagnosis of FHL. After interventions such as psychological counseling by our pediatrics and psychiatry departments, we compared the clinical profiles of patients in which hearing was "improved/normalized" and "unimproved". RESULTS Fourteen patients visited a pediatrician and two chose not to do so. A discrepancy between the maximum and minimum values of the four index scores was observed in all patients in which WISC-IV (the fourth version of the Wechsler Intelligence Scale for Children) was performed (n = 12). The discrepancy between the verbal comprehension index (VCI) and perceptual reasoning index (PRI) was significantly greater in "unimproved" patients than in "improved/normalized" patients. Hearing improved, or was normalized, after intervention in six of 16 patients. CONCLUSIONS Developmental imbalances were suspected in all 12 children who visited a pediatrician and completed the WISC-IV. Cooperation with pediatricians, psychiatrists, and other health professionals is desirable in supporting patients diagnosed with FHL.

Abstract
BACKGROUND Long-term voice-abuse or sudden vocal fold microvascular disruption can lead to injury and subsequent repair/remodeling of the vocal fold mucosa. Periostin is known to be involved in airway remodeling and in various otolaryngological diseases. In ischemic heart disease, increased CD31 expression has been observed around cardiomyocytes during remodeling, and endothelial proliferation has been reported to occur at these sites. OBJECTIVES We investigated the expression and the roles of CD31, CD34, and periostin in the formation of vocal fold polyps. MATERIALS AND METHODS Fifty-seven samples of vocal fold polyps were investigate histopathologically and immunohistochemically. RESULT Expression of CD31 and CD34 was detected in 41 (71.9%) and 53 (93.0%) samples, respectively, obtained from patients with vocal fold polyp. Expression of periostin was detected in 41 (71.9%) samples obtained from patients with vocal polyps. The vocal polyp samples could be classified into three histological subtypes. Three patterns of CD31 and CD34 expression were observed in the vocal polyp. Four patterns of periostin expression were observed in vocal polyps. An association was observed between the CD31 expression pattern and the histological subtype of vocal fold polyps. CONCLUSION AND SIGNIFICANCE In vocal fold polyps, evaluation of vascular endothelial markers may be useful for staging.

Abstract
INTRODUCTION Chronic rhinosinusitis (CRS) comprises several heterogenous groups, now classified based on endotype more often than on phenotype. A number of studies aimed at finding a useful biomarker for type 2 CRS suggest that periostin is a promising surrogate. AREAS COVERED A comprehensive overview of the clinical significance of tissue periostin expression and serum periostin in CRS patients is provided. The effects of comorbid asthma on serum periostin and samples other than serum in which periostin can be detected in CRS patients are also discussed. Moreover, the functional roles of periostin in CRS pathogenesis are summarized. EXPERT OPINION The position of periostin as a signature biomarker of type 2 CRS has been well established, enabling us to classify CRS patients by endotyping. Serum periostin is useful not only for endotyping CRS patients, but also for estimating disease severity, comorbidity, prognosis, and response to treatment, and in particular, predicting recurrence after surgery. However, it remains to be addressed how we apply serum periostin to using biologics for CRS patients. Further studies aimed at showing periostin to be a therapeutic target for CRS are awaited.

Abstract
OBJECTIVES Branchial cleft cysts (BCCs) are common in daily practice, however, BCC patients suffer aesthetic problems due to postoperative scars on visible parts after surgery. To analyze the feasibility, surgical outcomes and possible risks and complications encountered during a facelift procedure for patients with BCC. METHODS This retrospective analysis examined patients who had undergone surgery for branchial cleft cyst using a facelift procedure (n = 16) or conventional transcervical resection (n = 20) at our institutes between April 2015 and August 2021. RESULTS There was no significant difference between the groups that underwent the facelift procedure or conventional transcervical resection as to the average size of the cysts, operating time, bleeding, drain out, or recurrence. None of the patients needed to switch from the facelift procedure to conventional transcervical resection. In all the patients in the facelift procedure group, postoperative scars were fully concealed by the auricle and hair. However, four patients in the facelift procedure group experienced a transient auricular complication after surgery. CONCLUSION The facelift procedure provides adequate visualization, workspace and excellent cosmetic results in suitably selected cases with BCC.

Abstract
The Practical Guideline for the Management of Allergic Rhinitis, the fist guideline for allergic rhinitis in Japan, was prepared after a symposium held by the Japanese Society of Allergology in 1993. The current 9th edition was published in 2020 and is widely used today. The most recent collection of evidence from the literature was supplemented to the revised guideline to incorporate evidence-based medicine. The revised guideline includes updated epidemiology of allergic rhinitis in Japan, a figure representing the mechanisms of allergic rhinitis in both the onset and sensitization phases with the introduction of regulatory T cells and type 2 innate lymphoid cells, practical assessment for diagnosis, new pharmacotherapy agents such as anti-IgE mAb and a new drug delivery system for antihistamines, sublingual immunotherapy for children, dual sublingual immunotherapy for house dust mites and Japanese cedar pollen extract, new classification for surgery for allergic rhinitis, and treatment and prescriptions for older adults. An evidence-based step-by-step strategy for treatment is also described.

Abstract
BACKGROUND Patients with eosinophilic chronic rhinosinusitis (ECRS) respond poorly to many treatment modalities. Overproduction of periostin in the nasal mucosa is reported to contribute to polyp formation. This study examined periostin levels in patients with ECRS in comparison with levels in patients with non-ECRS. METHODS Fifty-nine patients with chronic rhinosinusitis were grouped into those with ECRS and those with non-ECRS. We compared the relationships between peripheral blood eosinophil level, serum periostin level, histopathological findings, clinical and laboratory findings, nose findings, diagnostic score of the Japanese Epidemiological Survey of Refractory Eosinophilic Chronic Rhinosinusitis Study, and postoperative recurrence of nasal polyps in each group. RESULTS In the ECRS group, a positive correlation was found between peripheral blood eosinophil level and serum periostin level (rs = 0.49, P < 0.01: Spearman's rank correlation coefficient). ROC curve analysis was used to evaluate the serum periostin level that could predict postoperative recurrence of nasal polyps in the ECRS group: the area under the curve (AUC) was 0.95, sensitivity was 92%, and specificity was 100%; the serum periostin cutoff value for postoperative recurrence of nasal polyps was 130 ng/ml. In ROC curve analysis to evaluate peripheral blood eosinophil level, the AUC was 0.73, sensitivity was 69.2%, and specificity was 85.0%; the cutoff value was 8.8%. CONCLUSIONS periostin was implicated in the pathophysiology of ECRS. Periostin shown to be a more useful biomarker than eosinophils in ECRS. Periostin was shown to likely be an important biomarker for pathological severity of ECRS and postoperative recurrence of nasal polyps.

Abstract
The olfactory epithelium can regenerate after damage; however, the regeneration process is affected by various factors, such as viral infections, head trauma, and medications. Zinc is an essential trace element that has important roles in organ development, growth, and maturation. Zinc also helps regulate neurotransmission in the brain; nevertheless, its relationship with olfactory epithelium regeneration remains unclear. Therefore, we used a severe zinc deficiency mouse model to investigate the effects of zinc deficiency on olfactory epithelium regeneration. Male wild-type C57BL/6 mice were divided into zinc-deficient and control diet groups at the age of 4 weeks, and methimazole was administered at the age of 8 weeks to induce severe olfactory epithelium damage. We evaluated the olfactory epithelium before and 7, 14, and 28 days after methimazole administration by histologically analyzing paraffin sections. RNA sequencing was also performed at the age of 8 weeks before methimazole administration to examine changes in gene expression caused by zinc deficiency. In the zinc-deficient group, the regenerated olfactory epithelium thickness was decreased at all time points, and the numbers of Ki-67-positive, GAP43-positive, and olfactory marker protein-positive cells (i.e. proliferating cells, immature olfactory neurons, and mature olfactory neurons, respectively) failed to increase at some time points. Additionally, RNA sequencing revealed several changes in gene expression, such as a decrease in the expression of extracellular matrix-related genes and an increase in that of inflammatory response-related genes, in the zinc-deficient group. Therefore, zinc deficiency delays olfactory epithelium regeneration after damage in mice.

Abstract
The commonest sites for liposarcoma are the retroperitoneum and lower extremities. Liposarcoma of the head and neck region is a rare and potentially life-threatening malignancy. Tumors originating in the right cervical space cause special diagnostic and therapeutic difficulties. In the present report, we describe a case of differentiated liposarcoma of the right cervical region. The tumor continued to grow slowly over 3 years before a definitive diagnosis was established. Extended extirpation of the tumor was performed and proved efficacious in that no recurrence has been observed for 4 years. Recommendations for earlier and accurate diagnosis and treatment of this rare neoplasm are discussed.

Abstract
Objective/Hypothesis Middle ear cholesteatoma is characterized by abnormal growth of the keratinizing squamous epithelium of the temporal bone. d‐β‐aspartic acid is the major isomer of d‐aspartic acid found in elderly tissue. We assessed the immunoreactivity to k‐β‐aspartic acid of congenital and acquired middle ear cholesteatomas. Study Design Case–control studies. Material and Methods Tissue samples were collected from 21 patients comprising 21 ears with congenital middle ear cholesteatoma and 26 patients comprising 29 ears with acquired type. Their clinical and histopathological features were investigated. We divided the middle ear cholesteatoma samples into three layers: the perimatrix, matrix, and cystic contents. The patterns of immunoreactivity to d‐β‐aspartic acid expression were then assessed immunohistochemically. Results Two patterns of immunoreactivity to d‐β‐aspartic acid were detected in middle ear cholesteatoma: infiltrative and diffuse. In congenital middle ear cholesteatoma, d‐β‐aspartic acid expression was observed throughout all the layers (perimatrix, matrix, and cystic contents), and immunoreactivity to d‐β‐aspartic acid was dramatically strong in all layers. The expression levels of d‐β‐aspartic acid to the cystic content and perimatrix were significantly higher in congenital middle ear cholesteatoma than in the acquired type. Conclusions This study showed the expression levels of d‐β‐aspartic acid in middle ear cholesteatoma to differ significantly between congenital and acquired middle ear cholesteatoma. Our results indicate that overexpression of d‐β‐aspartic acid is likely to be involved in the pathogenesis of cholesteatoma, and we speculate that d‐β‐aspartic acid could be a novel biomarker for, and a therapeutic target in, congenital and acquired middle ear cholesteatoma.

Abstract
Background The human monoclonal antibody dupilumab blocks interleukin (IL)‐4 andIL‐13, key and central drivers of type 2 inflammation. Dupilumab, on background mometasone furoate nasal spray (MFNS), improved outcomes in the phase III SINUS‐52 study (NCT02898454) in patients with severe chronic rhinosinusitis with nasal polyps (CRSwNP). This posthoc analysis of SINUS‐52 examined whether eosinophilic status of CRSwNP was a predictor of dupilumab efficacy. Methods Patients were randomized 1:1:1 to dupilumab 300 mg every 2 weeks (q2w) until week 52; dupilumab 300 mg q2w until Week 24, then 300 mg every 4 weeks until week 52; or placebo (MFNS) until week 52. Coprimary endpoints were change from baseline in nasal polyps score (NPS), nasal congestion (NC), and Lund‐Mackay score assessed by CT (LMK‐CT) at week 24. Patients (n = 438) were stratified by eosinophilic chronic rhinosinusitis (ECRS) status according to the Japanese Epidemiological Survey of Refractory Eosinophilic Rhinosinusitis algorithm. Results Dupilumab significantly improved NPS, NC, and LMK‐CT scores versus placebo at week 24 in all ECRS subgroups (p < 0.001), with improvements maintained or increased at week 52 (p < 0.001). There was no significant interaction between ECRS subgroup (non‐/mild or moderate/severe) and dupilumab treatment effect for all endpoints at weeks 24 and 52 (p > 0.05), except LMK‐CT at week 24 (p = 0.0275). Similar results were seen for the secondary endpoints. Dupilumab was well tolerated across all ECRS subgroups. Conclusion Dupilumab produced consistent improvement in symptoms of severe CRSwNP irrespective of ECRS status. Therefore, blood eosinophil level may not be a suitable biomarker for dupilumab efficacy in CRSwNP.

Abstract
Ticks are blood-sucking arthropods that transmit many pathogens, including arboviruses. Arboviruses transmitted by ticks are generally referred to as tick-borne viruses (TBVs). TBVs are known to cause diseases in humans, pets, and livestock. There is, however, very limited information on the occurrence and distribution of TBVs in sub-Saharan Africa. This study was designed to determine the presence and distribution of ticks infesting dogs and cattle in Ghana, as well as to identify the tick-borne or tick-associated viruses they harbour. A more diverse population of ticks was found to infest cattle (three genera) relative to those infesting dogs (one genus). Six phleboviruses and an orthonairovirus were detected in tick pools screened by RT-PCR. Subsequent sequence analysis revealed two distinct phleboviruses and the previously reported Odaw virus in ticks collected from dogs and a virus (16GH-T27) most closely related to four unclassified phleboviruses in ticks collected from cattle. The virus 16GH-T27 was considered a strain of Balambala tick virus (BTV) and named BTV strain 16GH-T27. Next-generation sequencing analysis of the BTV-positive tick pool detected only the L and S segments. Phylogenetic analysis revealed that BTV clustered with viruses previously defined as M-segment-deficient phleboviruses. The orthonairovirus detected in ticks collected from cattle was confirmed to be the medically important Dugbe virus. Furthermore, we discuss the importance of understanding the presence and distribution of ticks and TBVs in disease prevention and mitigation and the implications for public health. Our findings contribute to the knowledge pool on TBVs and tick-associated viruses.

Abstract
BACKGROUND There are few studies on taste or acoustic reflex (AR) in patients after recovery from facial muscle paralysis (FMP). OBJECTIVES To investigate the recovery of AR and taste in patients who have recovered from peripheral facial nerve palsy (FNP). MATERIALS AND METHODS The study included 25 patients whose FMP had resolved after treatment for FNP. A difference in taste threshold of ≤4 dB between the affected and unaffected sides in the electric taste test was defined as normal; an AR on the affected side was assessed to be ≥90% of the AR on the unaffected side was defined as normal. RESULTS Six months after treatment, 8% of patients with FNP who had recovered from FMP still showed taste disorders, and 60% of patients showed abnormal AR. The number of subjects whose electric taste threshold was normal after treatment was significantly higher than the number of subjects whose AR assessment was normal (p < .01). CONCLUSION AND SIGNIFICANCE This study demonstrates that even among subjects whose FMP is resolved after treatment for FNP, there are some whose taste and AR do not recover. Physicians should be aware of ear symptoms persisting after facial muscle recovery.

Abstract
BACKGROUND Pneumonia is a common cause of illness and death of the elderly in Japan. Its prevalence is escalating globally with the aging of population. To describe the latest trends in pneumonia hospitalizations, especially aspiration pneumonia (AP) cases, we assessed the clinical records of pneumonia patients admitted to core acute care hospitals in Miyagi prefecture, Japan. METHODS A retrospective multi-institutional joint research was conducted for hospitalized pneumonia patients aged ≥20 years from January 2019 to December 2019. Clinical data of patients were collected from the medical records of eight acute care hospitals. RESULTS Out of the 1,800 patients included in this study, 79% of the hospitalized pneumonia patients were aged above 70 years. The most common age group was in the 80s. The ratio of AP to total pneumonia cases increased with age, and 692 out of 1,800 patients had AP. In univariate analysis, these patients had significantly older ages, lower body mass index (BMI), a lower ratio of normal diet intake and homestay before hospitalization, along with more AP recurrences and comorbidities. During hospitalization, AP patients had extended fasting periods, more swallowing assessments and interventions, longer hospitalization, and higher in-hospital mortality rate than non-AP patients. A total of 7% and 2% AP patients underwent video endoscopy and video fluorography respectively. In multivariate analysis, lower BMI, lower C-reactive protein, a lower ratio of homestay before hospitalization, a higher complication rate of cerebrovascular disease, dementia, and neuromuscular disease were noted as a characteristic of AP patients. Swallowing interventions were performed for 51% of the AP patients who had been hospitalized for more than two weeks. In univariate analysis, swallowing intervention improved in-hospital mortality. Lower AP recurrence before hospitalization and a lower ratio of homestay before hospitalization were indicated as characteristics of AP patients of the swallowing intervention group from multivariate analysis. Change in dietary pattern from normal to modified diet was observed more frequently in the swallowing intervention group. CONCLUSION AP accounts for 38.4% of all pneumonia cases in acute care hospitals in Northern Japan. The use of swallowing evaluations and interventions, which may reduce the risk of dysphagia and may associate with lowering mortality in AP patients, is still not widespread.

Abstract
<b>Introduction:</b> Recurrent thyroglossal duct cyst after surgery is not a rare condition and first-line treatment has not been established yet.<br/><br/> <b>Aim:</b> Evaluation of outcomes and complications of OK-432 treatment in patients with recurrent thyroglossal duct cyst after surgery. <br/><br/> <b>Material and methods:</b> This study is designed as a case series with planned data collection at Tohoku Medical and Pharmaceutical University and Fukase Clinic. Five patients with recurrent thyroglossal duct cyst after surgery received this therapy between January 2014 and February 2020 on an outpatient basis, without hospitalization. OK-432 solution was injected into the lesion using an 18- or 27-gauge needle, depending on the location and size of the lesion, as well as on possible complications.<br/> <br/> <b>Results:</b> Lesions showed marked reduction or total shrinkage in all patients, with no local scarring or deformity at the injection site. Side effects manifested as local pain at the site of injection and fever (37.5-38.5°C) observed in three patients, but the symptoms resolved within a few days.<br/> <br/> <b>Conclusions:</b> Since OK-432 therapy is simple, easy, safe and effective, it can be used as an alternative to surgery in the treatment of recurrent thyroglossal duct cyst after surgery.

Abstract
<b>Objective:</b> The feasibility, surgical outcomes and possible risks and complications encountered during a facelift procedure for patients with parapharyngeal space (PPS) tumor were analyzed. <br><b>Method:</b> This retrospective analysis examined 10 patients who underwent surgery for PPS tumor using a facelift incision at our institutes between April 2015 and August 2019. <br><b>Results:</b> This study included four retro-styloid (benign nerve sheath tumor) and six pre-styloid tumors (pleomorphic adenoma). Mean tumor dimensions were 4.1 x 4.2 x 3.8 cm respectively. None of the patients needed conversion to conventional open resection. Transient sensory changes in the auricle occurred in 30% of the patients; however, all recovered within four months. In all the patients, postoperative scars were fully concealed by the auricle and hair. No recurrences were detected during a mean follow-up period of 16.6 months. <br><b>Conclusion: </b>The facelift procedure provides adequate visualization, workspace and excellent cosmetic results in properly selected cases.

Abstract
Background Dengue virus (DENV) is a mosquito-borne arbovirus transmitted by Aedes mosquitoes, but is not endemic in all areas where this vector is found. For example, the relatively sparse distribution of cases in West Africa is generally attributed to the refractory nature of West African Aedes aegypti (Ae. aegypti) to DENV infection, and particularly the forest-dwelling Ae. aegypti formosus. However, recent studies have shown these mosquitoes to be competent vectors within some West African countries that have suffered outbreaks in the past, such as Senegal. There is however little information on the vector competence of the Ae. aegypti in West African countries such as Ghana with no reported outbreaks. Methods This study examined the vector competence of 4 Ae. aegypti colonies from urban, semi-urban, and two rural locations in Ghana in transmitting DENV serotypes 1 and 2, using a single colony from Vietnam as control. Midgut infection and virus dissemination were determined by quantitative reverse transcription polymerase chain reaction (qRT-PCR), while the presence and concentration of DENV in the saliva of infectious mosquitoes was determined by the focus forming assay. Results There were significant differences in the colonies’ susceptibility to virus infection, dissemination, and transmission. All examined Ghanaian mosquitoes were refractory to infection by DENV serotype 2, while some colonies exhibited potential to transmit DENV serotype 1. None of the tested colonies were as competent as the control group colony. Conclusions These findings give insight into the possible risk of outbreaks, particularly in the urban areas in the south of Ghana, and highlight the need for continuous surveillance to determine the transmission status and outbreak risk. This study also highlights the need to prevent importation of different DENV strains and potential invasion of new highly vector-competent Ae. aegypti strains, particularly around the ports of entry.

Abstract
A 49-year-old Japanese man presented with a rare case of sinonasal leiomyosarcoma with left nasal bleeding for 12 months. He had no history of irradiation or malignancies, including retinoblastoma. Preoperative histological examination suggested vascular leiomyoma. Complete resection with endoscopic surgery was performed. Histological examination during the operation suggested that the tumor was a leiomyoma. However, immunohistochemical staining for α smooth muscle actin and desmin were helpful in establishing a definitive diagnosis of sinonasal leiomyosarcoma. The resection margins were positive for tumor cells. Staging with CT of the neck and thorax, ultrasound of the abdomen, and MRI of the head ruled out metastases. Second endoscopic tumor resection surgery was performed for positive resection margins. The patient's condition was successfully managed with additional excision, and he remains well with no evidence of recurrence and metastasis 36 months after treatment. Endoscopic management should be considered in suitable cases.

Abstract
INTRODUCTION Eosinophilic chronic rhinosinusitis (ECRS) is a refractory chronic disease defined by recurrent nasal polyps with severe eosinophilic infiltration. This is mainly due to enhanced type 2-dominant immune responses, but the underlying mechanism is still not fully understood. OBJECTIVE AND METHODS In the present study, we aimed to determine the characteristics of dendritic cells (DCs) and cytokine profiles of T cells in the peripheral blood of individuals with ECRS and age- and sex-matched healthy controls (HC). RESULTS AND CONCLUSION The ratios of myeloid (m)DC1s to DCs and PD-L1+ mDC1s to mDC1s were higher in ECRS patients than in HC. The proportions of plasmacytoid (p)DCs in DCs, and human leukocyte antigen-DR+ pDCs and ILT3+ pDCs in pDCs were lower in ECRS patients than in HC. In a characterization of T cells, IL-4+CD4+, IFN-γ+CD4+, IL-4+IFN-γ+CD4+, IL-4+Foxp3+CD4+, IFN-γ+Foxp3+CD4+, IFN-γ+IL-4-Foxp3-CD4+, IL-4+CD8+, IL-4+IFN-γ+CD8+, and IL-4+Foxp3+CD8+ T-cell populations were significantly higher in ECRS patients than in HC. These results suggest that the enhanced immune regulation of mDC1, diminished capacity of pDCs, and increased proportion of the T-cell phenotypes in peripheral blood might be factors in ECRS pathogenesis.

Abstract
Epstein-Barr virus (EBV) establishes lifelong latent infection in the majority of healthy individuals, while it is a causative agent for various diseases, including some malignancies. Recent high-throughput sequencing results indicate that there are substantial levels of viral genome heterogeneity among different EBV strains. However, the extent of EBV strain variation among asymptomatically infected individuals remains elusive. Here, we present a streamlined experimental strategy to clone and sequence EBV genomes derived from human tonsillar tissues, which are the reservoirs of asymptomatic EBV infection. Complete EBV genome sequences, including those of repetitive regions, were determined for seven tonsil-derived EBV strains. Phylogenetic analyses based on the whole viral genome sequences of worldwide non-tumour-derived EBV strains revealed that Asian EBV strains could be divided into several distinct subgroups. EBV strains derived from nasopharyngeal carcinoma-endemic areas constitute different subgroups from a subgroup of EBV strains from non-endemic areas, including Japan. The results could be consistent with biased regional distribution of EBV-associated diseases depending on the different EBV strains colonizing different regions in Asian countries.

Abstract
A 79-year-old Japanese woman presented with a rare case of metastatic renal cell carcinoma to the left sphenoid sinus with left nasal bleeding. She had previously had right radical nephrectomy for renal cell carcinoma at the age of 64 years and brain and spinal cord infarction at 74 years. Endoscopic examination revealed no mass in the nasal cavity. CT and MRI revealed a tumor in the left sphenoid sinus. The size of the tumor increased gradually from 12 to 15 years after the radical nephrectomy. Complete resection with endoscopic surgery was performed without preoperative embolization. The tumor cells had clear cytoplasm and were arranged in a trabecular pattern lined by a layer of endothelial cells. These findings were identical to the pathological findings of the surgical specimen of the renal cell carcinoma from 15 years previous. A pathological diagnosis of metastatic renal cell carcinoma of clear cell type (grade 1) was made. PET-CT demonstrated no metastasis. The patient's condition was successfully managed with excision of the tumor, and she remains well with no evidence of recurrence and metastasis 36 months after treatment. Metastatic renal cell carcinoma to the sphenoid sinus is rare, but it might be considered in the differential diagnosis of masses in the paranasal sinus even long after initial treatment of renal cancer.

Abstract
Immunoglobulin G4-related disease (IgG4-RD) is a recently recognized disease, characterized by high serum IgG4 concentrations and IgG4-producing plasma cell expansion with fibrotic or sclerotic changes in affected organs. Recent work has focused on the relationship between IgG4-RD and malignancies, but there is no report of malignancies associated with IgG4-RD in head and neck regions. The aim of this study was to analyze the clinicopathological characteristics of malignancies in patients with IgG4-RD in head and neck regions. We retrospectively analyzed 26 patients with IgG4-RD (12 men and 14 women aged 60.6 ± 11.6 years). The mean follow-up period was 26.6 months (from 12 to 96 months). These patients were divided into single-lesion group (n = 12) with IgG4-RD only in head and neck regions and multiple-lesion group (n = 14) with IgG4-RD in other regions. There was no significant difference in serum IgG4 concentrations between the single-lesion group (459.4 ± 336.4 mg/dL) and the multiple-lesion group (908.0 ± 739.2 mg/dL) (P = 0.07), whereas the IgG4/IgG ratio was significantly lower in the single-lesion group (22.8 ± 11.0%; n = 11) compared with the multiple-lesion group (31.7 ± 15.0%; n = 11, P = 0.02). Among the 26 patients, two patients (7.7%), both in the multiple-lesion group, developed life-threatening malignancies (salivary duct carcinoma in the submandibular gland and lymphoma in the orbital tissue). All physicians need to keep in mind the possible coexistence of malignancies in patients with IgG4-RD with high IgG4/IgG ratio and multiple lesions at the time of diagnosis.

Abstract
HIV-associated salivary gland disease refers to the pathology in head and neck lesions such as ranula, salivary gland swelling, xerostomia, and benign lymphoepithelial cysts in the parotid gland. Here, we present a unique case of the ranula patient with HIV infection treated with OK-423 sclerotherapy. Case report: The patient was a 42-year-old Japanese male with a few months history of oral floor swelling. Computed tomography (CT) showed a low-density area limited within the right floor of the mouth. Magnetic resonance imaging (MRI) revealed a distinct T2-high intensity area localized on the same location. The puncture fluid was bloody mucus, and the cytology was no malignancy. We diagnosed a simple ranula. He was, however, found to be HIV-antibody positive at the examination before treatment by chance. He was referred to the department of infectious diseases and definitively diagnosed HIV infection by western blot. We chose OK-432 sclerotherapy because of its minimally invasive and the risk of HIV infecting medical staff. Two times OK-432 injection made the lesion disappear. Conclusion: The case indicated that OK-432 sclerotherapy could be effective for ranula related to HIV.

Abstract
We present the case of a 58-year-old Japanese woman with a natural killer T (NK/T)-cell lymphoma complicated by brain abscess. NK/T-cell lymphomas represent a rare type of lymphoma derived from either activated NK cells or, rarely, cytotoxic T cells. They are aggressive Epstein-Barr virus (EBV)-associated lymphomas that involve mainly the nasal cavity. Brain abscess associated with primary extranodal nasal-type NK/T-cell lymphoma is extremely uncommon: to our knowledge, this is the first reported case of this lymphoma with brain abscess as the initial clinical manifestation. Endoscopic surgery was performed for definitive diagnosis under intraoperative navigation system. Chemotherapy followed by radiotherapy was performed and was effective: 72 months later the tumor has not recurred. Recommendations of endoscopic management for diagnosis and treatment of this rare neoplasm are discussed.

Abstract
Entomological surveillance is one of the tools used in monitoring and controlling vector-borne diseases. However, the use of entomological surveillance for arboviral infection vector control is often dependent on finding infected individuals. Although this method may suffice in highly endemic areas, it is not as effective in controlling the spread of diseases in low endemic and non-endemic areas. In this study, we examined the efficiency of using entomological markers to assess the status and risk of arbovirus infection in Ghana, which is considered a non-endemic country, by combining mosquito surveillance with virus isolation and detection. This study reports the presence of cryptic species of mosquitoes in Ghana, demonstrating the need to combine morphological identification and molecular techniques in mosquito surveillance. Furthermore, although no medically important viruses were detected, the importance of insect-specific viruses in understanding virus evolution and arbovirus transmission is discussed. This study reports the first mutualistic relationship between dengue virus and the double-stranded RNA Aedes aegypti totivirus. Finally, this study discusses the complexity of the virome of Aedes and Culex mosquitoes and its implication for arbovirus transmission.

Abstract
BACKGROUND There have been no studies of dual administration of sublingual immunotherapy (SLIT) tablets for perennial and seasonal allergic rhinitis. This trial (JapicCTI-184014) was conducted to investigate the safety profile and immunological response during dual therapy with SQ house dust mite (HDM) and Japanese cedar pollen (JCP) SLIT tablets. METHODS This was a multicenter, open-label, randomized trial of 109 Japanese patients with coexisting HDM and JCP allergic rhinitis who had positive tests for HDM- and JCP specific IgE (≥0.7 kU/L). Patients were allocated to receive HDM (N = 54) or JCP (N = 55) SLIT tablets alone for 4 weeks followed by 8 weeks of dual therapy with both SLIT tablets administered within 5 min of each other. Adverse events (AEs), adverse drug reactions (ADRs), and serum IgE and IgG4 specific for HDM (Dermatophagoides farinae, Dermatophagoides pteronyssinus) and JCP were recorded. RESULTS The percentage of subjects with AEs and ADRs was similar between the two groups and between the two periods of monotherapy and dual therapy. Most AEs and ADRs were mild in severity, and no serious events were observed. The most common ADRs were local events in the oral cavity. Levels of IgE and IgG4 specific for HDM (D. farinae, D. pteronyssinus) and JCP were increased after treatment with HDM and JCP SLIT tablets, respectively. CONCLUSIONS Dual therapy with both SLIT tablets administered within 5 min after 4 weeks of monotherapy with HDM or JCP tablet was well tolerated and induced the expected immunological responses.

Abstract
Merkel cell carcinoma (MCC) is a rare but aggressive neuroendocrine skin cancer. To diagnose nodal MCC with an unknown primary disease is challenging, and it has to be separated from other nodal metastatic neoplasms. We report a unique case of nodal MCC in head and neck lesions with an unknown primary. A 70-year-old woman was admitted to our department with a right submandibular mass. Fine needle aspiration biopsy was performed and indicated malignancy. F-18-fluorodeoxyglucose positron emission tomography (PET) demonstrated abnormal accumulation in the right submandibular lymph node, right palatine tonsil, and right thyroid gland. For diagnostics and treatment, bilateral selective neck lymph node dissection, right tonsillectomy, and right thyroidectomy were performed. Histopathological examination revealed that most parts of the submandibular lymph node were occupied by diffuse sheets of tumor cells. Contrary to our expectation, malignant cells were not detected in the right palatine tonsil and right thyroid. Immunohistochemistry demonstrated a marked positive reaction for AE1/AE3, chromogranin A, synaptophysin, cytokeratin 20 (CK20) and CD56 and a negative reaction for vimentin, leucocyte common antigen (LCA), thyroid transcription factor-1 (TTF1) and cytokeratin 7 (CK7) in the tumor cells. Immunostaining of Merkel cell polyomavirus-large T antigen (MCPyV-LT) showed a positive reaction and MCPyV-positive MCCs were assessed by PCR analysis, demonstrating that viral copy number was 12.8 copies per cell. These histological findings confirmed the diagnosis of Merkel cell carcinoma of the lymph node. In cases of tumors in the lymph node with a neuroendocrine appearance in head and neck lesions, it is necessary to eliminate the possibility of metastasis from MCC.

Abstract
In recent years, the prevalence of invasive Streptococcus dysgalactiae subsp. equisimilis (SDSE) infections has increased gradually throughout the world, including Japan. Here, we report the case of an abdominal aortic graft infection caused by stG485.0, ST29 SDSE in an elderly patient with diabetes. The patient was an 86-year-old man who had undergone surgery 10 years ago for treating a non-infected abdominal aortic aneurysm using a bifurcated graft. He was referred to our hospital after being suspected of having an abdominal aortic graft infection based on computed tomography (CT) scans. He underwent surgery to drain the pus that had accumulated between the aneurysm and graft. Although blood cultures were negative, the surgical specimen culture was positive for a β-hemolytic group G streptococci, which was subsequently identified as SDSE using 16S ribosomal RNA sequencing. Genetic relationships deduced from emm and multilocus sequence typing revealed the isolate to be types stG485.0 and ST29, respectively. Although aortic aneurysm graft infection has a poor prognosis, we successfully rescued the patient through prompt surgery and identification of the responsible pathogen. This case indicates that attention must be paid toward possible SDSE infections in the field of vascular surgery.

Abstract
A 71-year-old Japanese male patient presented with a rare case of Glomangiopericytoma (GPC) of the left nasal with obstruction. Complete resection with endoscopic surgery was performed. Immunohistochemical staining for smooth muscle actin, β catenin, cyclin D1, vimentin, and factor 13 were helpful in establishing a definitive diagnosis. Extranasal treatment has been traditionally performed for successful management. However, recent advances in endoscopic treatment have enabled complete endoscopic resection of GPC, minimizing morbidity and facilitating subsequent surveillance for recurrence. Endoscopic management should be considered in suitable cases.

Abstract
The sphenopalatine ganglion (SPG) is a gathering of the cell bodies of parasympathetic fibers that dominate the nasal gland, lacrimal gland and cerebral blood vessels. The SPG controls nasal secretions, tears, and the dilation of cerebral blood vessels. However, it is unclear how serotonin regulates SPG functions. In this study, we investigated the expression of genes involved in the serotonergic system in the mouse SPG. We examined the mRNA expression levels of 5-HT1A, 5-HT1B, 5-HT1D, 5-HT1F, 5-HT2A, 5-HT2B, 5-HT2C, 5-HT3A, 5-HT3B, 5-HT4, 5-HT5A, 5-HT5B, 5-HT6 and 5-HT7 receptors, as well as serotonin transporter, tryptophan hydroxylases 1 and 2, and L-amino acid decarboxylase (AADC) by RT-PCR. It revealed that the 5-HT3A and 5-HT3B ionotropic receptors and AADC were likely to be highly expressed in the SPG, as measured by RT-PCR. We next performed in situ hybridization on the SPG to examine the expression of these three genes at the cellular level after validating the specificity of each cRNA probe by northern blotting. The 5-HT3A receptor, 5-HT3B receptor, and AADC were expressed in 96.5% ± 1.0%, 29.7% ± 10.7%, and 57.4% ± 2.9% of neuronal cell bodies in the SPG, respectively, indicating that the 5-HT3A receptor was virtually expressed in all SPG neurons. Our results on the expression of these critical serotonin system genes in the parasympathetic SPG provide insight into the pathogenetics of rhinitis, conjunctivitis and headache. Furthermore, our findings suggest that targeting the 5-HT3A receptor might have therapeutic potential in the treatment of these ailments.

Abstract
OBJECTIVE To clarify the roles of 11 beta-HSD in resistance to glucocorticoid therapy for allergic rhinitis, a case series study was conducted. METHODS The patient group consisted of 20 subjects with allergic rhinitis, aged from 21 to 46 years (mean age 26.5), who showed persistent GC resistance necessitating surgical removal of the inferior turbinate after 6 months' GC treatment. The patients with poor response to GC treatment for 6 months' were defined as GC resistance. The control group consisted of 10 subjects aged from 16 to 39 years (mean age 24.5) who underwent maxillofacial surgery, from whom nasal tissues were taken and who did not receive GC treatment. Nasal mucosal tissues from patients and cntorol subjects were examined immunohistochemically. The sections were washed with 0.01 M phosphate-buffered saline (PBS; pH 7.2) containing 0.15 M NaCl and 0.01% Triton X-100, and incubated for 2 h with rabbit polyclonal anti-11 beta HSD1 and 11 beta-HSD2 antibody (Santa Cruz Biotechnology, Inc., Santa Cruz, CA, USA), each diluted 1:200 in PBS containing 0.1% bovine serum albumin. Immunostained sections were assessed under an Olympus microscope with an eyepiece reticule at 200 X magnification. Cell counts are expressed as means per high-power field (0.202 mm2). Control group means (arithmetic mean ± SD) were compared with patient group means by Mann-Whitney U-test at P = 0.05. RESULTS Although 11 beta-HSD1 was expressed to a similar extent in patients and controls, 11 beta-HSD2 was expressed significantly more in patients with severe allergic rhinitis, resulting in a increased HSD-1/HSD-2 ratio. The significantly increased expression of 11 beta-HSD2 in the nasal epithelium and submucosal inflammatory cells of patients with severe nasal allergy were observed in the present study. CONCLUSION Our findings suggest that 11 beta-HSD2 plays an important role in resistance to glucocorticoid therapy for allergic rhinitis, and its expression might be used as an additional parameter indicating steroid resistance in allergic rhinitis.

Abstract
Recent evidence suggests that 1α,25-dihydroxyvitamin D3 (VD3), the active form of vitamin D, inhibits microbial proliferation. Previously, we used in vivo murine models to investigate the antimalarial activity of VD3 and confirmed potent antimalarial activity in the acute phase. This study aimed to clarify the mechanisms underlying the antimalarial activity of VD3 in vivo, particularly extensive inhibition of parasitemia in the acute phase, focusing on nitric oxide (NO), a potent antimalarial molecule. VD3 is a good NO inducer. When most Plasmodium chabaudi AS (PcAS)-infected mice treated with VD3 survived, NO was present in blood samples obtained from VD3-treated mice at a significantly higher rate at 2 and/or 3 days post-infection than that in vehicle-treated control mice. To verify the involvement of NO in the antimalarial activity of VD3, we used aminoguanidine (AG), an inducible NO synthase (iNOS) inhibitor, to abrogate the antimalarial activity of VD3. However, despite AG-induced reductions in NO levels, parasitemia remained inhibited during the acute phase, even in the presence of AG, and the antiplasmodial faculty of VD3 was not ablated. VD3-mediated antimalarial activity irrelevant of NO compelled us to consider another candidate. In a pilot experiment, we used cathelicidin (CAMP), an antimicrobial peptide, since it is known that VD3 induces CAMP synthesis. Serum CAMP levels increased on days 4 or 5 post-infection with or without VD3 administration, but experiments using exogenous CAMP did not display curative effects in PcAS-infected mice. The present study using VD3 to target the malarial parasite thus suggests a potential novel approach to treat malarial infections.

Abstract
Visceral leishmaniasis (VL) is a major problem worldwide and causes significant morbidity and mortality. Existing drugs against VL have limitations, including their invasive means of administration long duration of treatment regimens. There are also concerns regarding increasing treatment relapses as well as the identification of resistant clinical strains with the use of miltefosine, the sole oral drug for VL. There is, therefore, an urgent need for new alternative oral drugs for VL. In the present study, we show the leishmanicidal effect of a novel, oral antimalarial endoperoxide N-251. In our In vitro studies, N-251 selectively and specifically killed Leishmania donovani D10 amastigotes with no accompanying toxicity toward the host cells. In addition, N-251 exhibited comparable activities against promastigotes of L. donovani D10, as well as other L. donovani complex parasites, suggesting a wide spectrum of activity. Furthermore, even after a progressive infection was established in mice, N-251 significantly eliminated amastigotes when administered orally. Finally, N-251 suppressed granuloma formation in mice liver through parasite death. These findings indicate the therapeutic effect of N-251 as an oral drug, hence suggest N-251 to be a promising lead compound for the development of a new oral chemotherapy against VL.

Abstract
Dengue fever is known to be one of the most common arthropod-borne viral infectious diseases of public health importance. The disease is now endemic in more than 100 countries in Africa, the Americas, the Eastern Mediterranean, Southeast Asia and the Western Pacific with an estimated two fifths of the world's population being at risk. The notable endemic viral hemorrhagic fevers (VHFs) found in West Africa, including yellow fever, Lassa fever, Rift Valley fever, dengue fever and until recently Ebola have been responsible for most outbreaks with fatal consequences. These VHFs usually produce unclear acute febrile illness, especially in the acute phase of infection. In this study we detected the presence of 2 different serotypes (DENV-2 and DENV-3) of Dengue virus in 4 sera of 150 patients clinically suspected of Ebola virus disease during the Ebola Virus Disease (EVD) outbreak in West Africa with the use of serological and molecular test assays. Sequence data was successfully generated for DENV-3 and phylogenetic analysis of the envelope gene showed that the DENV-3 sequences had close homology with DENV-3 sequences from Senegal and India. This study documents molecular evidence of an indigenous Dengue fever viral infection in Ghana and therefore necessitates the need to have an efficient surveillance system to rapidly detect and control the dissemination of the different serotypes in the population which has the potential to cause outbreaks of dengue hemorrhagic fevers.

Abstract
A new high performance liquid chromatography (HPLC) method has been established for quantitative and qualitative analysis of three tetracyclic iridoids: ML-2-3 (1), molucidin (2), and ML-F52 (3), which are responsible for anti-trypanosomal and anti-leishmanial activities of Morinda lucida Bentham leaves. Separation of 1-3 from dried 80% aqueous (aq.) ethanol extract was achieved on a reversed-phase cholester column packed with cholesteryl-bonded silica using an acetonitrile-0.1% aq. formic acid mobile phase system. Ultraviolet-visible (UV-VIS) spectroscopy was employed for detection of compounds, and their contents were determined by measuring absorbance at 254 nm. Depending on the above system, several factors potentially affecting the concentration of tetracyclic iridoids were evaluated resulting in several variation on plant organs, seasonality, variation between individual trees, and branch positions within the trees. Moreover, we developed a simple, quick, and effective method for tetracyclic iridoid isolation from M. lucida leaves that consisted of extraction by sonication into 80% aq. ethanol, basic hydrolysis, acid neutralization, liquid-liquid extraction into an organic solvent, and reverse phase open column chromatography. Employing this method, we have succeeded to obtain 1 as a colorless crystal yielding of 0.23%, which was 28 times higher than that of previous isolation method. Setting up methodology in this paper may be important for future in vitro and in vivo studies of tetracyclic iridoids and moreover for their applications in new drug design and development.
