OBJECTIVES: The study of short-term effects of environmental ozone exposure on nasal airflow, lung function, and airway inflammation METHODS:: Ninety one children-47 underwent rhinomanometry-were included. The study was carried out during the 2013 to 2014 academic year. Activity questionnaires and personal O3 samplers were distributed and 1 week later, respiratory measurements were performed. Daily measurements of outdoor ozone were also considered. RESULTS: A 10 μg/m increase in weekly personal ozone exposure concentrations was associated with a non-statistically significant 12...

BACKGROUND: We previously reported a higher prevalence of nasal obstructive disorders (NOD) in pediatric patients with persistent allergic rhinitis (PER) not responding to medical treatment. The aim of this study was to determine the impact of NOD on quality of life (QoL) in this population. METHODS: Real-life prospective study including 142 patients (41 children, 6-11 yo and 101 adolescents, 12-17 yo) with moderate and severe PER. After two months of medical treatment (intranasal steroids and antihistamines) patients were asked if their symptoms had improved (yes/no) and classified accordingly in R, responders and NR, non-responders...

Study Objectives: To determine whether arousals that terminate obstructive events in obstructive sleep apnea (OSA): 1. Induce hypocapnia and 2. Subsequently reduce genioglossus muscle activity following the return to sleep. Methods: 31 untreated OSA patients slept instrumented with: sleep staging electrodes, nasal mask and pneumotachograph, end-tidal CO2 monitoring and intramuscular genioglossus electrodes. End-tidal CO2 was monitored and respiratory arousals were assigned an end-arousal CO2 change value (PETCO2 on the last arousal breath minus each individual's wakefulness PETCO2)...

Adenotonsillar regrowth in children after adenotonsillectomy (T&A) for obstructive sleep apnea (OSA) is often seen in clinical treatment, however, the relationship between allergic disease and adenotonsillar regrowth remains unclear. In this retrospective study, children were assigned to either the recurrence or control group, and subdivided by age at operation. Among children over 36 months, those in the recurrence group had more allergic disease and higher IgE, IL-4, and IL-5 levels than the same-aged children in control group...

Objective Efficacy of maxillomandibular advancement (MMA) in the treatment of obstructive sleep apnea (OSA) is associated with degree of maxillary advancement. Large maxillary advancement leads to profound changes of the nasolabial region. We present the incidence and indications of post-MMA corrective nasal surgery in a large cohort.

CASE DESCRIPTION A 4-hour-old 6.3-kg (13.9-lb) female alpaca cria was evaluated because of severe respiratory distress and difficulty nursing since birth. CLINICAL FINDINGS The cria had open-mouth breathing and cyanotic membranes, with no airflow evident from either nostril. Supplemental oxygen was delivered, and the patient was anesthetized and intubated orotracheally; a CT evaluation of the head confirmed bilateral membranous obstruction of the nasal cavities, consistent with complete bilateral choanal atresia...

Obstructive sleep apnoea (OSA) constitutes the most prevalent form of abnormal respiratory control during sleep in adults. Evidence linked OSA to cardiovascular disease, and the role of OSA in abnormal blood pressure (BP) control has been extensively studied. Although longitudinal trials suggest a causative role of OSA in the development of hypertension, the evidence is not fully consistent. Nasal continuous positive airway pressure (nCPAP) applied during sleep is well documented and a highly efficient therapeutic aid to eliminate OSA...

BACKGROUND: The surgical excision of anatomic obstructions such as adenoids, palatine or lingual tonsils are commonly performed in children with sleep disordered breathing (SDB). Imaging studies measuring airway changes post-surgery in the SDB pediatric population are scarce, rarely addresses the nasal cavity, and are based on global measures (e.g. volume) that do not represent the complexity of the upper airway anatomy. The purpose of this pilot is to test the feasibility in using cone beam CT (CBCT) to analyze the nasal and pharyngeal airway space post-surgery using meaningful methods of analyses, and correlating imaging findings with clinical outcomes in children with SDB symptoms and maxillary-mandibular disproportion...

BACKGROUND: Several correlations between morphological and/or positional alterations of the jaws and respiratory functional impairments have been reported. NAO (Nasal airway obstruction) represents a big deal with no clearly defined "gold- standard" in measurement. Rhinomanometry was adopted by multiple Authors to evaluate whether patients with malocclusion developed respiratory functional changes after an orthodontic-surgical treatment. However there are contrasting findings in literature regarding the possibility of improving respiratory function by means of SARPE or bimaxillary repositioning of the bony bases...

OBJECTIVE: There is a paucity of literature discussing prognostic factors or comparing outcomes in eosinophilic angiocentric fibrosis (EAF). This review aims to analyze tumor and patient characteristics as possible prognostic markers and compare surgical approaches. METHODS: Systematic literature review and case report analyzing available cases of EAF located within the paranasal sinuses. RESULTS: The literature search yielded 39 articles meeting criteria for a total of 59 cases (including 1 from our institution)...

OBJECTIVES: Congenital nasal pyriform aperture stenosis (CNPAS) is one of several causes of neonatal respiratory distress. Congenital nasal pyriform aperture stenosis can be diagnosed by clinical presentation and evaluated by computed tomography for degree of stenosis. Surgical management of indicated cases involves drillout of pyriform aperture with placement of stents. The following case presents a novel approach to choice of stent in these patients. CASE PRESENTATION: We report the case of an infant diagnosed with CNPAS who underwent surgical correction at 9 days of life, with placement of mometasone fuorate stents...

Septorhinoplasty is a commonly performed procedure for facial aesthetics and obstructed nasal breathing. There have been only 4 reported cases of methicillin-resistant Staphylococcus aureus (MRSA)-associated postoperative complications following septorhinoplasty reported in the literature across all specialties. In this article, we report a case of MRSA-associated infection after an uncomplicated septorhinoplasty. Risk stratification and outcome of treatment are described, followed by a review of the current literature...

Objective: To review the clinical data of cases of primary ciliary dyskinesia (PCD), and to explore the clinical characteristics for the understanding of PCD. Methods: We retrospectively summarized 17 patients with PCD diagnosed in Peking Union Medical College Hospital from Jan 2009 to Dec 2014. There were 7 male and 10 female patients, with the age from 6 to 57 years at the time of diagnosis. The mean onset age of the disease was 11.7±2.1 years, and the mean age at diagnosis was 29.5±3.5 years. We analyzed their clinical symtoms, radiologic images, pulmonary function test and the electron microscopic findings for the clinical characteristics of PCD...

We examined gastric outlet obstruction (GOO) patients who received two weeks of strengthening pre-operative enteral nutrition therapy (pre-EN) through a nasal-jejenal feeding tube placed under a gastroscope to evaluate the feasibility and potential benefit of pre-EN compared to parenteral nutrition (PN). In this study, 68 patients confirmed to have GOO with upper-gastrointestinal contrast and who accepted the operation were randomized into an EN group and a PN group. The differences in nutritional status, immune function, post-operative complications, weight of patients, first bowel sound and first flatus time, pull tube time, length of hospital stay (LOH), and cost of hospitalization between pre-operation and post-operation were all recorded...

Allergic inflammation in the upper airways represents a wide-spread health issue: Little is known about whether it increases sensitivity to airborne chemicals thereby challenging established exposure limits that neglect such differences in susceptibility. To investigate the role of pre-existing allergic inflammation, 19 subjects with seasonal allergic rhinitis (SAR) and 18 control subjects with low risk of sensitization were exposed for 4h to ammonia in two concentrations (cross-over design): 2.5ppm (odor threshold) and 0-40ppm (occupational exposure limit: 20ppm TWA)...
