Pulmonary artery sling (PAS) is a rare disease frequently associated with severe malacia and stenosis of the trachea. We present a two-day-old newborn that underwent urgent surgery for PAS and needed prolonged respiratory support afterward. Temporary airway stenting above the level of the tracheal bifurcation was performed five days after surgery to overcome severe airway obstruction caused by tracheomalacia and laceration of the tracheal mucosa after diagnostic bronchoscopy. Two days after the procedure, the child could be extubated and after two weeks the stent was removed without complications...

The metabonomic techniques were used to study the changes in endogenous metabolites between urines of rats in normal physiological conditions and bovine serum albumin induced allergic reactions, identify potential biomarkers associated with allergic reactions, and then analyze the metabolic pathways and the metabolic mechanisms of allergic reactions. The bovine serum albumin-induced allergic reactions in rats were adopted as a model to detect histamine and tryptase in rat serum and observe the issue morphology of lungs and trachea in rats...

Arteriovenous (AV) malformations of the face are rare presentations. Endovascular coiling is one of the treatment modalities. We report a case of a 65-year-old lady who presented with a large AV malformation of the face located around the nasal bride and alae nasae posted for coiling under general anesthesia. Anesthetic management of the case was a challenge as it was an anticipated difficult airway situation. Furthermore, any pressure on the swelling can lead to rupture and hemorrhage as the skin above swelling was unhealthy...

While it is clear that the insect tracheal system can respond in a compensatory manner to both hypoxia and hyperoxia, there is substantial variation in how different parts of the system respond. However, the response of tracheal structures, from the tracheoles to the largest tracheal trunks, have not been studied within one species. In this study, we examined the effect of larval/pupal rearing in hypoxia, normoxia, and hyperoxia (10, 21 or 40 kPa oxygen) on body size and the tracheal supply to the flight muscles of Drosophila melanogaster, using synchrotron radiation micro-computed tomography (SR-µCT) to assess flight muscle volumes and the major tracheal trunks, and confocal microscopy to assess the tracheoles...

Invasion of the trachea is observed in ~6% of patients with differentiated thyroid carcinoma (DTC), and surgery is accepted as the treatment of choice. However, surgical procedures can be challenging and are associated with various risks. The authors of the present study performed a retrospective study of patients with DTC and tumor invasion of the trachea. Outcomes from patients that received circumferential sleeve resection (CSR) of the trachea followed by anastomosis in the absence of suprahyoid release (n=21; CSR group) and patients that underwent tangential resections [n=103; tangential 'shave' resection (TSR) group) were analyzed...

BACKGROUND: Dysfunction in cystic fibrosis transmembrane conductance regulator (CFTR) can be elicited by cigarette smoke and is observed in patients with chronic bronchitis. We have previously demonstrated in human airway epithelial cell monolayers that roflumilast, a clinically approved phosphodiesterase 4 inhibitor that reduces the risk of exacerbations in chronic obstructive pulmonary disease patients with chronic bronchitis and a history of exacerbations, activates CFTR-dependent chloride secretion via a cAMP-mediated pathway, partially restores the detrimental effects of cigarette smoke on CFTR-mediated ion transport, and increases CFTR-dependent gastrointestinal fluid secretion in isolated murine intestine segments...

OBJECTIVE: Upper airway malacia highly complicates the treatment of benign laryngotracheal stenosis, and no ideal option is available to date. We here explore the use of extraluminal biodegradable splints in an animal model of long-segment anterior tracheomalacia (TM). We show the efficacy, as well as the tissue tolerance, of a custom-made biodegradable extraluminal device surgically inserted around the trachea. STUDY DESIGN: Preclinical animal study. METHODS: Anterior TM was induced in rabbits through an anterior neck approach by removing eight consecutive anterior tracheal rings without damaging the underlying mucosa...

BACKGROUND: The forced oscillation technique (FOT) is a non-invasive means of measuring respiratory resistance and reactance. We tested our hypothesis that endotracheal intubation would cause more substantial preoperative increases in FOT parameters than a supraglottic airway device (SGD). METHODS: Forty patients requiring general anesthesia and mechanical ventilation for transurethral bladder tumor resection underwent spirometry the day before surgery. Forced oscillation was measured using a MostGraph-01 device the day before surgery and immediately after removal of the airway adjunct...

BACKGROUND: A tracheostomy is a surgically created opening through the anterior neck tissues and the trachea, into which a tube is inserted. Despite its influence on basic human needs such as respiration, communication and nutrition, little is known about the impact of tracheostomy on patients and their caregivers or what could be done to enable better care and quality of life (QoL) for these individuals. OBJECTIVE: The aim of this review was to better understand the current knowledge related to the experience and QoL of adults living with a tracheostomy and their caregivers so as to be able to improve these experiences...

Tracheobronchopathia osteochondroplastica (TPO) is a rare pathology characterized by a progressive segmentary stenosis of the respiratory tract due to proliferation of osteocartilagineous nodules in the lumen of the distal part of the trachea and large bronchial trunks. Prognosis is usually benign, but some cases with an acute progression and a lethal outcome have been described. Clinical presentation is non specific, the chest x-ray is generally normal and there are not typical radiological signs of suspicion: diagnosis of TPO is usually incidental...

The avian coronavirus infectious bronchitis virus (IBV) S1 subunit of the spike (S) glycoprotein mediates viral attachment to host cells and the S2 subunit is responsible for membrane fusion. Using IBV Arkansas-type (Ark) S protein histochemistry, we show that extension of S1 with the S2 ectodomain improves binding to chicken tissues. Although the S1 subunit is the major inducer of neutralizing antibodies, vaccination with S1 protein has been shown to confer inadequate protection against challenge. The demonstrated contribution of S2 ectodomain to binding to chicken tissues suggests that vaccination with the ectodomain might improve protection compared to vaccination with S1 alone...

The infectious bronchitis virus (IBV) causes a highly contagious disease [infectious bronchitis (IB)] that results in substantial economic losses to the poultry industry worldwide. We conducted a molecular and phylogenetic analysis of the S1 gene of Brazilian (BR) IBV isolates from a routinely vaccinated commercial flock of broiler breeders, obtained from clinical IB episodes that occurred in 24-, 46- and 62-week-old chickens. We also characterized the antigenicity, pathogenesis, tissue tropism and spreading of three IBV isolates by experimental infection of specific pathogen-free (SPF) chickens and contact sentinel birds...

We present a case of a patient with complete tracheal dehiscence and multiple false passages after recent tracheal resection and anastomosis. Loss of tracheal continuity after disruption of anastomosis with distal stump retraction presents a unique anesthetic challenge given lack of access to the trachea and the need for adequate anesthesia and analgesia for surgical neck dissection. Traditional airway management, including awake fiberoptic intubation, intubation via direct laryngoscopy, needle cricothyrotomy, and awake tracheostomy are not viable options...

Pertussis or whooping cough caused by the obligate human pathogen Bordetella pertussis is undergoing a world-wide resurgence. Majority of studies with this pathogen are conducted with laboratory-adapted strains which may not be representative of the species as a whole. Biofilm formation by B. pertussis plays an important role in its pathogenesis. We conducted a side-by side comparison of the biofilm forming ability of the prototype laboratory strains with currently circulating isolates from two countries with different vaccination programs...

Loss of function mutations in the enzyme 7-dehydrocholesterol reductase are responsible for the Smith-Lemli-Opitz syndrome, in which 7-dehydrocholesterol (7-DHC) levels are markedly increased in the plasma and tissues of patients. This increase in 7-DHC is probably associated with the painful and itchy photosensitivity reported by the large majority of Smith-Lemli-Opitz syndrome patients. In order to identify the molecular targets involved in the activation and photosensitization of primary afferents by 7-DHC we focused on TRPA1 and TRPV1, two ion channels expressed in nociceptive nerve endings and previously shown to respond to ultraviolet and visible light under pathophysiological circumstances...

Objective and importance Mounier Kuhn syndrome is usually diagnosed in adulthood, and only a few cases have been described in childhood. Clinical presentation We present the case of a seven-year-old boy suffering from recurrent pneumonia and atelectasis. Intervention Previously performed chest X-rays showed bilateral hyperinflation and tracheobronchomegaly. Chest computed tomography (CT) confirmed the presence of distal enlargement of trachea and bronchi. Tracheobronchomegaly associated with recurrent respiratory tract infections is consistent with Mounier Kuhn syndrome...

Hemorrhagic septicemia is a highly infectious and contagious disease caused by Pasteurella multocida serogroup B:2 in tropical Asian and African countries. The acute inflammatory responses induced by Pasteurella multocida are the main cause of death in hemorrhagic septicemia. Therefore, present study was undertaken to examine the blood cytokine expression profiles (TNF-α, IL-1β, and IL-6), bacterial colonization and histopathological changes of intraperitoneally and subcutaneously challenged vaccinated and unvaccinated mice with 10(2) CFU of P...
