BACKGROUND: The role of nasal nitric oxide (NO) in the diagnosis of allergic rhinitis (AR) is controversial. The aim of this study was to identify factors that may affect levels of nasal NO in AR patients and evaluate the role of nasal NO in the diagnosis of AR. METHODS: Seventy-five AR patients and 31 healthy controls were enrolled in this study. AR symptom scores were assessed using the visual analog scale. Eosinophil cationic protein (ECP) was detected by enzyme-linked immunoassay, nasal NO was measured using a chemiluminescence analyzer, and nasal airway resistance (NAR) was assessed by active anterior rhinomanometry...

BACKGROUND: Sinonasal exophytic papillomas are rare. The multifocal form, florid papillomatosis, has not been yet described in literature. We report on the clinical features and the management of the different forms of exophytic papilloma. METHODS: A retrospective study was conducted that included all patients with exophytic papilloma treated in our center over the past 12 years. We recorded clinical presentation, treatments, recurrences, pathology (p16 expression and human papillomavirus [HPV] status)...

BACKGROUND: Eosinophilic chronic rhinosinusitis (ECRS) is a disease characterized by eosinophilic inflammatory infiltrate and a local type 2 cytokine milieu. Current animal models fail to recapitulate many of the innate and adaptive immunologic hallmarks of the disease, thus hindering the development of effective therapeutics. In the present study, mice were exposed intranasally to the cysteine protease papain, which shares functional similarities with parasitic proteases and aeroallergens, to generate a rapidly inducible murine model of eosinophilic rhinosinusitis...

BACKGROUND: The rate of cardiovascular implantable electronic device infection (CIEDI) has increased, despite the use of perioperative antibiotics at the time of device placement or revision. This is due, in part, to the presence of multiple comorbid conditions in an elderly population, in general, who require CIED. Statins may have an antibacterial effect, although there is currently no evidence that the likelihood of CIEDI has been impacted by statin use. METHODS: A retrospective cohort study was performed to assess whether statins are associated with a reduced risk of CIEDI...

We present the case of a patient with Cushing's syndrome secondary to ectopic ACTH secretion. A MR of the head showed a left-sided nasal mass extending down from the cribriform plate. The patient underwent endoscopic resection with nearly complete removal of the mass. Histological examination showed an ACTH-secreting olfactory neuroblastoma (ONB). The patient's cortisol levels returned to normal range after surgery and have remained normal for over a year. ONB is a rare cause for ectopic ACTH secretion. This case highlights the diagnostic and management difficulties in patients with ectopic ACTH secretion, and provides a brief review of ONB...

Background: In Asian patients, nasal deviation secondary to augmentation rhinoplasty may result from underlying bony asymmetry that was not corrected intraoperatively. Diagnosis and treatment of this condition are complicated by the masking effect of dorsal implants. Objectives: The authors applied computed tomography (CT) to examine the causes of nasal deviation after augmentation rhinoplasty. CT results were utilized in preoperative planning for revisional surgery...

Background: Recent literature has highlighted MRSA nasal screening as a possible antimicrobial stewardship program (ASP) tool for avoiding unnecessary empiric MRSA therapy for pneumonia, yet current guidelines recommend MRSA therapy based on risk factors. The objective of this meta-analysis was to evaluate the diagnostic value of MRSA nasal screening in MRSA pneumonia. Methods: Pubmed and EMBASE were searched from inception to November 2016 for English studies evaluating MRSA nasal screening and development of MRSA pneumonia...

REVIEW
Shigeru Kuratani, Per E Ahlberg
The subdivision of the gnathostome neurocranium into an anterior neural crest-derived moiety and a posterior mesodermal moiety has attracted the interest of researchers for nearly two centuries. We present a synthetic scenario for the evolution of this structure, uniting developmental data from living cyclostomes and gnathostomes with morphological data from fossil stem gnathostomes in a common phylogenetic framework. Ancestrally, vertebrates had an anteroposteriorly short forebrain, and the neurocranium was essentially mesodermal; skeletal structures derived from premandibular ectomesenchyme were mostly anterior to the brain and formed part of the visceral arch skeleton...

We previously reported that some healthy individuals show alternating anisocoria. We now describe one such individual who also exhibits a classic nasal cycle (alternating periods of nasal congestion and decongestion). We made measurements of his pupil asymmetry and nasal asymmetry at 21 different time points and found that these variables were always synchronised such that greater nasal airflow was invariably found on the same side as the larger pupil. We hypothesise that a common central oscillator may be responsible for co-modulating the sympathetic outflow to both nasal vessels and iris dilator muscles in some healthy individuals...

BACKGROUND: Epidemiological evidence suggests the existence of a direct link between allergic rhinitis (AR) and asthma. Several studies also support the presence of small-airway dysfunction (SAD) in non-asthmatic children with AR. However, it remains unknown whether SAD can predict the progression of AR to asthma. Our objective was to explore the existence of SAD in non-asthmatic children with AR and to assessed its ability to predict the development of asthma. METHODS: Seventy-three 6-year-old children with intermittent moderate-severe AR but without asthma symptoms/medication within the last two years, underwent spirometry and measurement of respiratory resistance (Rrs) and reactance (Xrs) before and after bronchodilation (BD) (300mcg salbutamol)...

Oxytocin (OXT) is a cyclic nonapeptide, two amino acids of which are cysteine, forming an intramolecular disulfide bond. OXT is produced in the hypothalamus and is secreted into the blood stream from the posterior pituitary. As recent studies have suggested that OXT is a neurotransmitter exhibiting central effects important for social deficits, it has drawn much attention as a drug candidate for the treatment of autism. Although human-stage clinical trials of the nasal spray of OXT for the treatment of autism have already begun, few studies have examined the pharmacokinetics and brain distribution of OXT after nasal application...

The aim of this article is to analyse cone density, spacing and arrangement using an adaptive optics flood illumination retina camera (rtx1™) on a healthy population. Cone density, cone spacing and packing arrangements were measured on the right retinas of 109 subjects at 2°, 3°, 4°, 5° and 6° of eccentricity along 4 meridians. The effects of eccentricity, meridian, axial length, spherical equivalent, gender and age were evaluated. Cone density decreased on average from 28 884 ± 3 692 cones/mm2, at 2° of eccentricity, to 15 843 ± 1 598 cones/mm2 at 6°...

Objective To evaluate whether an adjuvant therapy of leukotriene receptor antagonists (LTRAs) based on oral H1-antihistamines (H1) can increase efficacy of allergic rhinitis (AR) treatment. Data Sources The search involved databases of PubMed, EMBASE, and Cochrane Central Register of Controlled Trials, from inception up to September 23, 2017. Randomized controlled trials (RCTs) that compared efficacy of LTRAs + H1 vs H1 alone were eligible. Review Methods Pooled comparative effects were measured using weighted mean difference (WMD) and 95% confidence interval (CI)...

BACKGROUND: Computational fluid dynamic (CFD) simulations have greatly improved the understanding of nasal physiology. We postulate that simulating the entire and repeated respiratory nasal cycles, within the whole sinonasal cavities, is mandatory to gather more accurate observations and better understand airflow patterns. METHODS: A 3-dimensional (3D) sinonasal model was constructed from a healthy adult computed tomography (CT) scan which discretized in 6.6 million cells (mean volume, 0...

BACKGROUND: Chronic rhinosinusitis with nasal polyps (CRSwNP) is known to have 2 phenotypes in East Asia. Eosinophilic CRSwNP (ECRSwNP), defined as tissue eosinophilia and easily recurrent, is distinguished from other non-eosinophilic CRSwNP (NECRSwNP) types. However, the pathogenesis of each remains unclear. METHODS: Nasal polyp tissues from ECRS (ECRSwNP) and NECRS (NECRSwNP) patients were obtained, and their comprehensive gene expression profiles were investigated by microarray analysis...
