Respiratory syndromes (RS) are among the most significant pathological conditions in food animals and are caused by complex coactions of pathogens and environmental factors. In poultry, low pathogenic avian Influenza A viruses, metapneumoviruses, infectious bronchitis virus, infectious laryngotracheitis virus, Mycoplasma spp. Escherichia coli and/or Ornithobacterium rhinotracheale (ORT) in turkeys, are considered as key co-infectious agents of respiratory syndromes. Aspergillus sp., Pasteurella multocida, Avibacterium paragallinarum or Chlamydia psittaci may also be involved in respiratory outbreaks...

The larynx sometimes requires repair and reconstruction due to cancer resection, trauma, stenosis, or developmental disruptions. Bioengineering has provided some scaffolding materials and initial attempts at tissue engineering, especially of the trachea, have been made. The critical issues of providing protection, maintaining a patent airway, and controlling swallowing and phonation, require that the regenerated laryngotracheal cartilages must have mechanical and material properties that closely mimic native tissue...

Viruses affecting poultry cause significant levels of disease leading to severe economic losses among poultry farmers worldwide. The Americas region continues to be vulnerable to the spread of poultry viruses across the continents and Caribbean island chains. In Trinidad and Tobago (T&T) there is limited information on the viruses circulating in poultry. Many flock are vulnerable to infection and there are occasional outbreaks of disease resulting in high levels of morbidity and mortality. This study aims to identify important viruses of poultry circulating in T&T through a broad-based surveillance approach...

Protection against diseases caused by the avian viruses, Marek's disease, Infectious laryngotracheitis, chicken anemia and turkey meningoencephalitis is achieved by live vaccines. The application quality is important to assure proper uptake in commercial flocks. We describe a novel evaluation method for the vaccination process by sequential monitoring the vaccine viruses in feathers. Feather collection is easy, non-invasive and non-lethal for the birds, therefore advantageous for monitoring purposes. To demonstrate the vaccine virus presence, an innovative assay of nested real-time amplification was approached because vaccine viruses presence in vivo is less abundant comparing to virulent wild-type isolates...

A one-step multiplex real-time reverse transcription-PCR (rRT-PCR) assay was developed for simultaneous detection and quantification of four avian respiratory viruses: avian influenza virus (AIV), infectious bronchitis virus (IBV), Newcastle disease virus (NDV) and infectious laryngotracheitis virus (ILTV). In comparison with the singleplex rRT-PCR, the specificity, the sensitivity and the reproducibility of the new assay were evaluated and validated using 70 clinical samples. The optimal cutoff point, the corresponding limit of quantification (LoQ) and the limit of detection (LoD) were statistical established based on receiver operating characteristic (ROC) curve analysis...

OBJECTIVES/HYPOTHESIS: Despite wide adoption of strategies to prevent injury from prolonged intubation and tracheotomy, acquired laryngotracheal stenosis (ALTS) has not disappeared. ALTS' persistence may be due to patient factors that confer unique susceptibility for some. We sought to identify genetic markers in genes associated with wound healing that could be associated with ALTS. STUDY DESIGN: Case-control study. METHODS: One hundred thirty-eight patients were recruited, 53 patients with ALTS and 85 control patients who underwent intubation or tracheotomy without evidence of ALTS...

OBJECTIVES: Significant advances in laryngotracheal reconstruction over the last few decades have revolutionised the management of paediatric patients with complex congenital or acquired airway stenosis. The primary aim of laryngotracheal reconstruction has focused primarily on airway and surgery specific outcomes, often at the expense of voice, as well as swallowing function, which are all intricately related. There is currently a paucity of data on swallowing outcome. The goal of this paper is to review and discuss the existing research on the impact of laryngotracheal on swallowing...

BACKGROUND: Granulomatosis with polyangiitis (GPA) is associated with development of subglottic stenosis in about one-fourth of all patients. Although endoscopic management is the primary treatment method for tracheobronchial stenosis, some patients have refractory disease, and tracheostomy is required. It is unclear if laryngotracheal resection and reconstruction (LTRR) can be safely performed in patients with GPA. METHODS: A retrospective review was performed of 11 patients with GPA undergoing LTRR...

Infectious laryngotracheitis virus (ILTV) is an alphaherpesvirus that infects chickens, causing upper respiratory tract disease and significant losses to poultry industries worldwide. Glycoprotein G (gG) is a broad range viral chemokine-binding protein conserved amongst most alphaherpesviruses, including ILTV. A number of studies comparing immunological parameters between infection with gG-expressing and gG-deficient ILTV strains have demonstrated that expression of gG is associated with increased virulence, modification of the amount and composition of the inflammatory response and modulation of immune responses towards antibody production and away from cell-mediated immune responses...

Acute respiratory tract infections are of paramount importance in the poultry industry. We developed an xTAG bead assay for the simultaneous detection and discrimination of avian influenza virus (AIV), Newcastle disease virus (NDV), infectious bronchitis virus (IBV) and infectious laryngotracheitis virus (ILTV). The assay lacked nonspecific reactions with other common avian viruses and the limit of detection was 6.75 × 10(2)- 3.52 × 10(3)copies/μL. We examined 60 clinical specimens and found 18 positive for respiratory viruses...

Laryngotracheal stenosis includes congenital laryngotracheal stenosis and secondary laryngotracheal stenosis. Congenital laryngotracheal anomalies are rare, accounting for 0.3%-1.0% of all laryngotracheal stenosis(LTS). Despite the management of pediatric LTS over the past 30 years had been considerable improved, primary surgery still failed in a significant number of complex LTS cases. In some severe LTS cases combined with glottic stenosis, the primary surgery failed around 30%, even with the latest available techniques...

Ultrasound is becoming a valuable diagnostic tool in the armamentarium of thoracic surgeons. We report its use to follow stent placement in the laryngotracheal position for management of life-threatening neoplastic obstruction. For this purpose, a 15-MHz linear probe was placed in the midline at the level of the cricoid cartilage. Ultrasound performed daily at bedside showed normal movement of vocal folds and no stent dislocation. This strategy may be an alternative to computed tomography scan or endoscopy to follow stent placement in extrathoracic airways...
