Surgery in Nasal Polyp Patients: Outcome After a Minimum Observation of 10 Years.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) often requires surgery, but recurrence even after surgery is common. Recurrence rates largely vary in literature and asthma seems to be a comorbid factor.

Objective: In this study, we aim to estimate disease recurrence during a long-term follow-up, together with the investigation of possible predicting and/or influencing parameters.

Local Allergic Rhinitis Revisited.

Purpose Of Review: Local allergic rhinitis (LAR) represents a diagnostic and therapeutic challenge for clinicians. Even though it affects a considerable number of chronic rhinitis patients and a significant number of articles regarding prevalence, evolution, diagnosis, and treatment have been published, the condition remains still largely unrecognized and therefore misdiagnosed and mistreated.

Recent Findings: LAR is a unique form of chronic rhinitis; it is neither classical allergic rhinitis (AR) nor non-allergic rhinitis (NAR).

Consensus guidance of nebulizer therapy for acute rhinosinusitis.

The guidance deals with the recommended applications, procedures, and safety management of nebulizer therapy for acute rhinosinusitis. In Japan, nebulizer therapy for sinusitis has been covered by public health insurance since 1958 and has been commonly carried out nationwide. The Japan Society for Infection and Aerosol in Otorhinolaryngology and the Oto-Rhino-Laryngological Society of Japan set up a working group to draw up a consensus guidance on nebulizer therapy for acute rhinosinusitis.

Sublingual Immunotherapy Attenuates Nasal Symptoms Upon Allergen Exposure in Murine Allergic Rhinitis Model via an Induction of IL-10 producing T cells in Submandibular Lymph Node.

Objective: Sublingual immunotherapy has been considered to be a painless and effective therapeutic treatment of patients with allergic rhinitis. Its mechanism of action has been elucidated, but there are still controversies among many reports between clinical efficacy and laboratory data. Therefore, its mechanism of action needs to be investigated further by using promising animal models such as rodents and monkeys.

Clinical Applications for Tissue Engineering in Rhinology.

Differentiating Rhinitis in the Paediatric Population by Giving Focus on Medical History and Clinical Examination.

Chronic rhinitis is defined as an inflammation of the nasal epithelium, and is characterized by the presence of two or more specific nasal symptoms including obstruction, rhinorrhea, sneezing, and/or itching for at least 12 weeks. In childhood, this clinical entity is very common and carries a significant socioeconomic burden. The impact on the physical, social, and psychological well-being of family cannot be underestimated.

Eosinophilic Upper Airway Inflammation in a Murine Model Using an Adoptive Transfer System Induces Hyposmia and Epithelial Layer Injury with Convex Lesions.

Background: Chronic rhinosinusitis with nasal polyps (CRSwNP) is a refractory upper airway disease, accompanied mainly by eosinophilia and/or asthma. In addition, the disease correlates with a high rate of hyposmia, following a marked infiltration of eosinophils into the inflamed site, the paranasal sinus. Although eosinophils are known to contribute to the development of hyposmia and CRSwNP pathology, the underlying mechanisms remain unclear.

Regulation of Interaction between the Upper and Lower Airways in United Airway Disease.

The concept of united airway disease comprises allergic rhinitis (AR) with asthma, and eosinophilic chronic rhinosinusitis (ECRS) with asthma. It embodies a comprehensive approach to the treatment of upper and lower airway inflammation. The treatment of upper airway inflammation reduces asthma symptoms and decreases the dose of inhaled corticosteroids (ICS) necessary to treat asthma.

Antihistamines for Allergic Rhinitis Treatment from the Viewpoint of Nonsedative Properties.

Antihistamines targeting the histamine H₁ receptor play an important role in improving and maintaining the quality of life of patients with allergic rhinitis. For more effective and safer use of second-generation drugs, which are recommended by various guidelines, a classification based on their detailed characteristics is necessary. Antihistamines for first-line therapy should not have central depressant/sedative activities.

OK-432 Administration Inhibits Murine Allergic Rhinitis at the Induction Phase, through the Macrophage Activation with TLR2 Signaling Pathway.

OK-432, a preparation of a low-virulence strain (Su) of (Group A) killed by a penicillin and lyophilized, is a stiff inducer of Th1 cytokines, and exerts anti-cancer effects in tumor-bearing mice. OK-432 has been reported to consist of many bacterial components, such as peptidoglycan, M-protein, etc. However, it is yet to be ascertained which bacterial component induces T helper 1 (Th1) responses.

Fibrous encapsulation of the peritoneal catheter in peritoneal shunt: Case report.

Background: The authors report a case of fibrous encapsulation of the peritoneal catheter, which caused peritoneal shunt malfunction, and has not previously been researched well as a complication of peritoneal shunts.

Case Description: A 69-year-old woman who had undergone a lumboperitoneal (LP) shunt for communicative hydrocephalus following subarachnoid hemorrhage caused by a ruptured aneurysm was identified with malfunction of the LP shunt system by dementia and gait disturbance. Hydrocephalus was revealed on computed tomography (CT).

Contemporary Use of Corticosteroids in Rhinology.

Purpose Of Review: Exogenously administered corticosteroids are widely used today in the field of rhinology. Allergic rhinitis (AR), non-allergic rhinitis (NAR), acute rhinosinusitis (ARS), chronic rhinosinusitis with (CRSwNP) and without (CRSsNP) nasal polyps, and autoimmune disorders with nasal manifestations are common diseases treated effectively with intranasal and oral glucocorticoids. We focus on physiological pathways, therapeutic benefits, indications, contra-indications, and side effects of glucocorticoid utilization in the treatment of rhinologic disorders such as AR, NAR, ARS, CRSsNP, and CRSwNP.

Japanese guidelines for allergic rhinitis 2017.

Like asthma and atopic dermatitis, allergic rhinitis is an allergic disease, but of the three, it is the only type I allergic disease. Allergic rhinitis includes pollinosis, which is intractable and reduces quality of life (QOL) when it becomes severe. A guideline is needed to understand allergic rhinitis and to use this knowledge to develop a treatment plan.

Short treatment time and excellent treatment outcome in accelerated hyperfractionated radiotherapy for T1 glottic cancer.

Accelerated hyperfractionated radiotherapy was performed as treatment for patients with T1 glottic cancer, and its utility was evaluated based on treatment outcomes and adverse effects. Fifty-eight men who had undergone radiotherapy were retrospectively reviewed. Tumor classification was Tis in 4 patients, T1a in 38, and T1b in 16.

The pathophysiology of the hygiene hypothesis.

There has been a considerable increase in the diagnosis of allergic diseases over the last decades. Prevalence of allergies in high-income countries and urban areas appears higher than in rural environments. While environmental factors like pollution or nutrition can be important, it is more likely that in the end they have a small association with allergies.

Sublingual Immunotherapy Induces Regulatory Function of IL-10-Expressing CD4(+)CD25(+)Foxp3(+) T Cells of Cervical Lymph Nodes in Murine Allergic Rhinitis Model.

Sublingual immunotherapy (SLIT) has been considered to be a painless and efficacious therapeutic treatment of allergic rhinitis which is known as type I allergy of nasal mucosa. Nevertheless, its mechanisms need to be further investigated. In this study, we constructed an effective murine model of sublingual immunotherapy in allergic rhinitis, in which mice were sublingually administered with ovalbumin (OVA) followed by intraperitoneal sensitization and nasal challenge of OVA.

Metronomic chemotherapy with low-dose cyclophosphamide plus gemcitabine can induce anti-tumor T cell immunity in vivo.

Several chemotherapeutic drugs have immune-modulating effects. For example, cyclophosphamide (CP) and gemcitabine (GEM) diminish immunosuppression by regulatory T cells (Tregs) and myeloid-derived suppressor cells (MDSCs), respectively. Here, we show that intermittent (metronomic) chemotherapy with low-dose CP plus GEM can induce anti-tumor T cell immunity in CT26 colon carcinoma-bearing mice.

Prevention of lung injury by Muc1 mucin in a mouse model of repetitive Pseudomonas aeruginosa infection.

Objective And Design: To determine whether repetitive airway Pseudomonas aeruginosa (Pa) infection results in lung inflammation and injury and, if so, whether these responses are affected by Muc1 mucin. Muc1 wild type (WT) and knockout (KO) mice were compared for body weights, lung inflammatory responses, and airspace enlargement using a chronic lung infection model system.

Materials: Mice were treated intranasally with Pa (10(7) CFU) on days 0, 4, 7 and 10.

Examination, diagnosis and classification for Japanese allergic rhinitis: Japanese guideline.

Many countries throughout the world have experienced an increase in the prevalence of allergic rhinitis (AR), which has come to be a major cause of morbidity in developed countries. The pathology underlying AR is regarded as IgE-mediated type I allergy characterized by mucosal inflammation that occurs in response to allergen exposure. In Japan, AR caused by Japanese cedar pollen, the most common allergic disease, has become a salient public health challenge.
