Despite the importance of Bordetella avium (BA) as a respiratory pathogen of young turkeys, no infection model for the evaluation of BA-vaccine efficacy is available. The objective of this study was to evaluate the influence of route and dose of infection on the establishment of a BA-challenge model. In our first experiment, 28-day-old turkeys were either inoculated oculonasally with 10(5), 10(7) or 10(9) colony forming units (CFU) of BA per animal or exposed to BA by aerosol with 10(5)-10(8) CFU/m(3). The respiratory tract of all inoculated animals was BA-colonised, which was confirmed by choanal swabs and samples of trachea and lung, showing the highest prevalence in the aerosol inoculated group...

Granular cell tumor (GCT) is a neoplasm of Schwann cell origin. Its presence in the aerodigestive tract is uncommon and becomes a diagnostic challenge on initial presentation. Our case is of a 59-year-old woman who presented to the emergency department with a history of productive cough and dyspnea associated with fever and chest pain. An initial chest X-ray (CXR) showed a right middle lobe consolidation with follow-up Computed Tomography (CT) scan showing a mass in the right bronchus. Bronchoscopy revealed a polypoid, sessile granular mass in the right bronchus intermedius with multiple white lesions in trachea, left main bronchus, and right upper bronchi...

The mouse bitter taste receptors Tas2r143, Tas2r135, and Tas2r126 are encoded by genes that cluster on chromosome 6 and have been suggested to be expressed under common regulatory elements. Previous studies indicated that the Tas2r143/Tas2r135/Tas2r126 cluster is expressed in the heart, but other organs had not been systematically analyzed. In order to investigate the expression of this bitter taste receptor gene cluster in non-gustatory tissues, we generated a BAC (bacterial artificial chromosome) based transgenic mouse line, expressing CreERT2 under the control of the Tas2r143 promoter...

OBJECTIVES: Diffuse idiopathic skeletal hyperostosis (DISH) is characterized by anterior ossification of the spine and can lead to dysphagia and airway obstruction. The morphology of the newly formed bone in the cervical spine is different compared to the thoracic spine, possibly due to dissimilarities in local vascular anatomy. In this study the spatial relationship of the new bone with the arterial system, trachea and esophagus was analyzed and compared between subjects with and without DISH...

Endotracheal intubation in rabbits can be challenging due to their unusual anatomy. Achieving a patent airway during anesthesia is critical for the avoidance of airway obstruction, prevention of gastric tympany, and to allow ventilatory support. Due to the difficulty of intubation, alternative methods such as the use of laryngeal mask airways or laryngeal tubes have been explored. However, these methods do not result in direct access to the trachea and thus may present a risk for development of complications...

Background/aim: Airway compression (AC) by vascular structures is an important complication of congenital heart disease (CHD) that often goes unrecognized. It is not easy to identify whether CHD patients require additional invasive examinations or not. Therefore, the present study aims to develop an AC diagnostic algorithm for CHD patients. Materials and methods: CHD patients with persistent respiratory symptoms that were treated between January 2007 and December 2015 were retrospectively reviewed. The following data were recorded for all CHD patients with AC: age, cardiac anomalies, the compressed structure, the airway diameter ratio (ADR), the compressing structure(s), treatment, and follow-up...

Vascular rings and slings may represent life-threatening compression of the esophagus and trachea. Such anatomic variants, although rare, are encountered by all thoracic surgeons in the scope of their practice at some time. The thoracic surgeon, whether treating such patients in the practice of congenital heart surgery, or in the practice of adult cardiac or thoracic surgery must have a requisite understanding of such anatomic variants, their diagnostic workup and radiologic interpretation, as well as their surgical management...

BACKGROUND: Tracheobronchomalacia, defined as variable collapse of the airways, has been recognized as an important cause of respiratory morbidity but still widely underdiagnosed. Bronchoscopy is still considered as the gold standard, but numerous limitations are known, especially for fragile sick children. Moreover, information on parenchymal lung disease cannot be described. There is a real need for a reliable, non-invasive test to help detection of airway and parenchymal malformations in children, specifically when bronchoscopy cannot be performed...

INTRODUCTION: Fever of unknown origin (FUO) is a common initial presentation leading to a diagnostic challenge. PATIENT CONCERNS: A 3-month history of moderate-to-high fever was reported in an otherwise healthy 54-year-old man. Enhanced computed tomography (CT) scans of his chest showed a remarkable progressive enlargement of bilateral cervical, supraclavicular, hilar, and mediastinal lymph nodes within 2 weeks. Bronchofibroscopy manifested obvious luminal stenosis with swelling, thick pale mucosa, and disappearing of structures of trachea cricoid cartilage, followed by a 18F-fluorodeoxyglucose positron-emission tomography-computed tomography (18F-FDG PET/CT) with intense symmetric FDG uptake in larynx, tracheobronchial tree, and hilar, mediastinal, and axillary lymph nodes being demonstrated...

Characterizing the immune cells of the head associated lymphoid tissues (HALT) and trachea during maturation in young birds is critical to understanding the immunological responses to avian respiratory diseases and vaccines. Selected mucosal leukocytes of the conjunctiva-associated lymphoid tissue (CALT), Harderian gland (HG), nasal associated lymphoid tissue (NALT) and trachea from 4, 6, 8 and 10-week-old chickens were enumerated and phenotyped. HG, NALT, and trachea cellularity increased as the birds aged with cell viability varying by tissue...

Demographic developments and medical progress will cause the already high prevalence of swallowing disorders to increase further in the future. With the same number of specialists and economic resources, it is necessary to improve the efficiency of dysphagia diagnostics and continue to offer patients a treatment concept tailored to their needs. Manifold and often co-existing causes of dysphagia require interdisciplinary cooperation in this area. Endoscopic swallowing diagnostics play a prominent role in dysphagia diagnostics and should always contain thorough endoscopy of the upper aerodigestive tract-the domain of the ENT specialist and phoniatrician...

The Staged Extubation Set has recently been introduced by Cook Medical for the management of difficult airway patients who potentially require reintubation; however, its reliability for intubation and ease of use is not reported in the literature. The set contains a wire and reintubation catheter with a central lumen for the wire and oxygenation if required. Reintubation is by a two-stage Seldinger-like technique. After induction of general anaesthesia, 23 low-risk elective surgical patients had the Staged Extubation Wire from the Cook set inserted into their trachea under direct laryngoscopy...

RATIONALE: Arytenoid dislocation is very rare and may be misdiagnosed as vocal cord paralysis or a self-limiting sore throat. PATIENT CONCERNS: A 70-year-old male (70 kg, 156 cm) was scheduled for transurethral resection of bladder tumors. A McGrath videolaryngoscope, with a basic cuffed Mallinckrodt oral tracheal tube of 7.5 mm internal diameter, was used to successfully intubate his trachea. The duration of surgery was 25 minutes. In the recovery room, he complained of sore throat and dyspnea with inspiratory stridor, which were not resolved after intravenous injection of 10 mg of dexamethasone...
