Higher Prevalence and Severity of Eosinophilic Otitis Media in Patients with Asthma-COPD Overlap Compared with Asthma Alone.

Introduction: Eosinophilic otitis media (EOM) is well-known to frequently co-exist with adult-onset asthma. Both diseases are similar type 2 inflammation and are considered to have a "one airway, one disease" relationship. Asthma-chronic obstructive pulmonary disease (COPD) overlap (ACO), characterized by airway obstruction caused by airway wall thickening (AWT), is a severe condition with a higher incidence of mortality compared to asthma alone or COPD alone.

Increased Expression of Activation-Induced Cytidine Deaminase in Sinus Mucosa from IgG4-Related Disease Patients with Comorbid Chronic Rhinosinusitis.

Objective: IgG4-related disease (IgG4-RD) is a systemic condition characterized by an elevated serum IgG4 level, localized infiltration of IgG4-positive plasma cells, and lesions in various organs. IgG4-RD also shows high rates of complication with allergic diseases and is often accompanied by elevated serum IgE levels. Reports in recent years have also shown high rates of complication with chronic rhinosinusitis (CRS) and its characteristic nasal manifestations.

Characteristics of patients with severe asthma who experienced treatment failure with omalizumab.

Background: Omalizumab, an anti-IgE antibody, has been widely used in many countries, including Japan. However, some patients do not respond to omalizumab, and the cause of treatment failure has not been fully elucidated.

Objective: This study aimed to evaluate the characteristics of adult asthma patients who failed to achieve disease control with omalizumab in a real-world setting.

Diagnostic Utility of Polymerase Chain Reaction for Paraffin-embedded Sinus Specimens for Rhinocerebral Mucormycosis Complicated by Internal Carotid Artery Thrombosis and Cerebral Infarction.

We herein report a 73-year-old man who experienced cerebral infarction caused by infection with a Mucromycocetes species. A delay in anti-fungal treatment might result in a lethal clinical outcome. We were unable to establish an accurate diagnosis based on histological findings and cerebrospinal fluid culture.

Eosinophilic otitis media and comorbid asthma.

Purpose Of Review: Eosinophilic otitis media (EOM) is an intractable otitis media characterized by numerous eosinophils infiltrating the middle ear cavity, which is part of the upper airway. EOM shows a high rate of comorbidity with asthma. They are considered to have a 'one airway, one disease' relationship.

Sialorrhea Successfully Treated by the Combined Use of Selective M1 and M3 Muscarinic Acetylcholine Receptor Antagonists.

Sialorrhea is often treated with anticholinergic agents, but they can have undesirable side effects such as drowsiness, sedation, and constipation. Effective medication that acts selectively on the salivary glands is needed. We report the case of a patient with sialorrhea who was successfully treated by the combined use of pirenzepine and solifenacin (M1 and M3 muscarinic receptor antagonists, respectively).

Tonsillectomy plus steroid pulse therapy is the most effective treatment in adult patients with C-Grade I IgA nephropathy, and the weight of the extracted palatine tonsils and Yamamoto scale have no significant correlation with the effects of this treatment.

Objective: We studied patients who underwent tonsillectomy plus steroid pulse therapy (TSP) for immunoglobulin A nephropathy (IgAN), in order to investigate the clinical factors associated with a positive response to this treatment.

Methods: We analyzed 118 IgAN patients who underwent TSP. We collected patients' data retrospectively, including age, sex, blood pressure, onset of IgAN, pathological findings of a renal biopsy, serum concentration of creatinine, estimated glomerular filtration rate, serum concentration of protein, urinary protein, hematuria, past history of tonsillitis, the Yamamoto scale, the weight and pathological findings of the extracted palatine tonsils, and the presence or absence of anti-platelet drugs and renin-angiotensin system inhibitors (RAS-I) usage.

Patients Over 60 Years of Age Have Poor Prognosis in Facial Nerve Decompression Surgery with Preserved Ossicular Chain.

Objective: We report our retrospective study of the recovery rate of auditory ossicles preserved facial nerve decompression surgery via the transmastoid approach in cases of both an electroneurography score of < 10% and a Yanagihara score of ≤8 in Bell's palsy and Ramsay Hunt syndrome.

Materials And Methods: We retrospectively reviewed 47 patients who we were able to follow-up for more than 6 months following the onset of palsy. The recovery rate was defined by the Japan Society for Facial Nerve Research or the Yanagihara score.

Optimal control of asthma improved eosinophilic otitis media.

Background: Eosinophilic otitis media (EOM) is often associated with comorbid asthma. The middle ear cavity is part of the upper airway. Therefore, EOM and asthma can be considered to be a crucial part of the "one airway, one disease" phenomenon.

Diagnostic and treatment effects of sialendoscopy for patients with swelling of the parotid gland when sialoliths are undetected with computed tomography.

Between August 2009 and May 2016, 74 patients underwent sialoendoscopic surgery. 32 patients had parotid gland disease and 9 patients had intermittent swelling of the parotid gland and sialoliths were not detected with CT imaging. 4 patients were diagnosed with idiopathic Stensen's duct stenosis.

Basophils are increased and express increased levels of interleukin-4 in the parotid lesions of Kimura disease.

Background: Kimura disease (KD) is a systemic soft-tissue disease that leads to formation of painless masses in lymph nodes, with the highest predilection for the head and neck and especially the parotid gland. KD lesions are characterized by marked eosinophil infiltration, production of IgE and increased expression of T-helper type 2 (Th2) cytokines (interleukin [IL]-4, IL-5, etc.).

Treatment outcomes of sialendoscopy for submandibular gland sialolithiasis: The minor axis of the sialolith is a regulative factor for the removal of sialoliths in the hilum of the submandibular gland using sialendoscopy alone.

Objective: To assess the general guidelines for the removal of sialoliths for submandibular gland sialolithiasis using sialendoscopy alone.

Methods: We analyzed 61 sialoliths treated using sialendoscopy in 42 patients with submandibular gland sialolithiasis. We evaluated the submandibular gland sialoliths and divided each case based upon the location: the Wharton's duct or the hilum.

The landmark for removal of sialoliths using sialendoscopy alone in parotid gland sialolithiasis.

Objective: To assess the general guidelines for removal of sialoliths in parotid gland sialolithiasis using sialendoscopy alone.

Methods: We analyzed 34 sialoliths treated using sialendoscopy in 26 patients with parotid gland sialolithiasis. We divided the Stensen's duct and parotid gland into for parts using computed tomography findings: (A) front of the masseter, (B) anterior and lateral to the center (anterolateral) of the masseter, (C) posterior and lateral to the center (posterolateral) of the masseter, (D) behind of the masseter.

Increased expression of thymic stromal lymphopoietin and its receptor in Kimura's disease.

Objective: The objective of this study was to investigate the expression of thymic stromal lymphopoietin (TSLP) and TSLP receptor (TSLPR) in Kimura's disease (KD).

Methods: Using parotid gland tissues from KD patients and control subjects, we quantified the expression levels of mRNA for TSLP, interleukin (IL)-25, IL-33, and their receptors by massively parallel sequencing. We also performed immunohistochemical analysis of TSLP and TSLPR, and counted cells immunoreactive for these proteins by the polymer immunocomplex and double immunofluorescence methods.

Eosinophilic otitis media is associated with asthma severity and smoking history.

Purpose: Eosinophilic otitis media (EOM) is an intractable otitis media characterized by an accumulation of eosinophils in the middle ear and a strong association with asthma. We investigated the relationship between EOM and asthma severity, asthma risk factors, lung function, and airway structural changes assessed by high-resolution computed tomographic (HRCT) scanning.

Materials And Methods: Forty-one asthma patients with chronic rhinosinusitis (18 men and 23 women; mean age 56 years; age range 25-82 years) were included in this study.

99mTcO4- accumulation in scintigraphy and expression of Na+/I- symporter in salivary gland tumors.

Objective: Warthin's tumors and oncocytomas show exceptionally good (99m)TcO4(-) (Tc) accumulation images in Tc scintigraphy. However, the mechanism of Tc accumulation in these tumors remains unclear. Sodium-iodide symporter (NIS) is a plasma membrane protein expressed in the thyroid, lactating breast, stomach and salivary glands; it facilitates uptake of I(-) and Tc.

Anti-IgE therapy to Kimura's disease: a pilot study.

Kimura's disease is a chronic disease that is characterized by subcutaneous granuloma of soft tissues in the head and neck region, increased eosinophil counts and high serum IgE levels. It is thought to be an IgE-mediated disease. Omalizumab, a monoclonal antibody, has recently been suggested as a potential new systemic treatment for IgE-mediated diseases, based on its efficacy in treating asthma and allergic rhinitis.

Improvement of eosinophilic otitis media by optimized asthma treatment.

Eosinophilic otitis media (EOM) shows a very high rate of association with asthma, and intractable otitis media involves marked eosinophil infiltration into the middle ear. The middle ear space is connected to the nasopharynx by the Eustachian tube, and it is considered a part of the upper respiratory tract. Allergic rhinitis and asthma often coexist as chronic inflammatory diseases of the upper and lower airways, respectively, and have an impact on each other.

Orally inhaled fluticasone propionate improved chronic rhinosinusitis with co-morbid asthma: report of a case.

Chronic rhinosinusitis and asthma are expressions of airway inflammatory diseases that frequently coexist, especially in the case of adult-onset asthma. Both conditions have similar pathological features, while one affects the upper airways and the other the lower airways. Whether the treatment of bronchial inflammation affects the severity of sinus disease remains an unanswered question.

A Case of Severe Asthma with Eosinophilic Otitis Media Successfully Treated with Anti-IgE Monoclonal Antibody Omalizumab.

A 51-year-old woman had been receiving medical treatment for asthma since she was 21 years old. However, her asthma was poorly controlled despite treatment involving combination inhalation of high-dose corticosteroid and long-acting β(2)-aderenergic agonist (LABA) and regularly taking oral steroids. Hearing loss and otorrhea appeared at the age of 44, and she was given a diagnosis of eosinophilic otitis media (EOM) and received medical treatment.

Expression and Roles of MMP-2, MMP-9, MMP-13, TIMP-1, and TIMP-2 in Allergic Nasal Mucosa.

Purpose: Allergic rhinitis (AR) and asthma share many characteristics, but structural changes are observed far less often in AR. Matrix metalloproteinases (MMPs) constitute a family of Zn-dependent endopeptidases that can decompose the extracellular matrix and basement membrane, and regulate cell infiltration. We analyzed the expression of MMPs and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs), in allergic nasal mucosa after nasal allergen challenge (NAC) and determined their relationship to inflammatory cells.

Decreased Expression of FOXP3 in Nasal Polyposis.

Purpose: The pathogenesis of nasal polyposis (NP) is unclear. Eosinophils and mast cells are considered to play important roles in this process. In addition, the levels of Th2-type cells are increased, irrespective of the atopic status of the patient with NP.

Increased expression and role of thymic stromal lymphopoietin in nasal polyposis.

Purpose: Nasal polyposis is a chronic inflammatory disease of the upper airways often associated with asthma and characterized by markedly increased numbers of eosinophils, Th2 type lymphocytes, fibroblasts, goblet cells and mast cells. Previous studies have shown elevated levels of thymic stromal lymphopoietin (TSLP) in atopic diseases like asthma, atopic dermatitis and mainly in animal models of allergic rhinitis (AR). Here, we investigated the expression of TSLP in nasal polyps from atopics and non-atopics in comparison with the nasal mucosa and its potential role in nasal polyposis.
