: Primary infection with varicella zoster virus (VZV), a neurotropic alpha herpesvirus, results in varicella. VZV establishes latency in the sensory ganglia and can reactivate later in life to cause herpes zoster. The relationship between VZV and its host during acute infection in the sensory ganglia is not well understood due to limited access to clinical specimens. Intrabronchial inoculation of rhesus macaques with simian varicella virus (SVV), recapitulates the hallmarks of VZV infection in humans...

Varicella Zoster Virus (VZV) is the causative agent of varicella and herpes zoster. Although it is well established that VZV is transmitted via the respiratory route, the host-pathogen interactions during acute VZV infection in the lungs remain poorly understood due to limited access to clinical samples. To address these gaps in our knowledge, we leveraged a nonhuman primate model of VZV infection where rhesus macaques are intrabronchially challenged with the closely related Simian Varicella Virus (SVV). Acute infection is characterized by immune infiltration of the lung airways, a significant up-regulation of genes involved in antiviral-immunity, and a down-regulation of genes involved in lung development...

We report a male patient who underwent bronchoscopic instillation of glue to control moderate hemoptysis which later led to the development of postobstructive pneumonia and extensive foreign body reaction in the bronchial wall and the lung distal to the glue application. He continued to have intermittent hemoptysis and underwent bronchial artery embolization. However, recurrent moderate hemoptysis eventually led to pneumonectomy, which showed severe foreign body reaction in bronchi- and post-obstructive changes in the lung parenchyma and the draining lymph nodes...

BACKGROUND: Hemoptysis is common in pulmonary aspergilloma. Current treatment modalities such as surgical resection or bronchial artery embolization (BAE) are limited by lack of technical expertise and risk of recurrence, respectively. We describe our experience of treating aspergilloma and hemoptysis with bronchoscopic instillation of voriconazole. METHODS: We retrospectively reviewed records of patients with symptomatic aspergilloma undergoing bronchoscopic voriconazole instillation...

BACKGROUND: Rigid bronchoscopy remains the gold standard in many countries to remove airway foreign bodies (FBs). We aimed to analyze the feasibility of airway FB removal in children, primarily by flexible bronchoscopy through a laryngeal mask. MATERIALS AND METHODS: Between 2008 and 2013 62 children with suspected airway FB who underwent flexible bronchoscopy were analyzed in a retrospective chart review at a tertiary university hospital with respect to clinical presentation and medical management...

Particles can be delivered to the respiratory tract of animals using various techniques. Inhalation mimics environmental exposure but requires large amounts of aerosolized NPs over a prolonged dosing time, varies in deposited dose among individual animals, and results in nasopharyngeal and fur particle deposition. Although less physiological, intratracheal (IT) instillation allows quick and precise dosing. Insufflation delivers particles in their dry form as an aerosol. We compared the distribution of neutron-activated (141)CeO2 nanoparticles (5 mg/kg) in rats after (1) IT instillation, (2) left intrabronchial instillation, (3) microspraying of nanoceria suspension and (4) insufflation of nanoceria dry powder...

BACKGROUND: After resection of the carina with a length of more than 4 cm, anastomoses often need to be performed under tension despite maximum mobilization. If the patient cannot be extubated, the anastomosis remains under continued stress. Anastomoses of the carina can be constructed using various suture techniques, including single interrupted sutures, back wall running but front wall single interrupted sutures, and complete running suture. This experimental study was designed to determine the most tensile stress-resistant anastomotic suture technique...

BACKGROUND: Bronchial occlusion therapy using silicon spigots is effective for intractable pneumothorax. However, sometimes the pneumothorax is refractory to bronchial occlusion because of collateral ventilation. For such difficult pneumothoraces, we attempted an intrabronchial infusion of autologous blood plus thrombin to control collateral ventilation and stop air leaks. METHODS: We performed bronchial occlusions using silicon spigots in patients with spontaneous pneumothorax secondary to emphysema and refractory to chest drainage, but which was inoperable owing to each patient's poor surgical candidacy and poor overall health condition...

BACKGROUND: Ex vivo lung perfusion (EVLP) presents a unique therapeutic opportunity to administer mesenchymal stromal cells (MSCs) to lung grafts before transplantation. We sought to determine the optimal route and dose of viable human umbilical cord-derived MSCs to be delivered into ex vivo-perfused damaged swine lungs, and to measure their effect on concentration of growth factors and inflammatory mediators. METHODS: Pig lungs were conventionally retrieved, cold preserved for 18 hours, and perfused normothermically ex vivo for 12 hours...

BACKGROUND: A persistent air leak represents significant clinical management problems, potentially affecting morbidity, mortality, and health care costs. In 2008, a unidirectional, intrabronchial valve received humanitarian device exemption for use in managing prolonged air leak after pulmonary resection. Since its introduction, numerous reports exist but no large series describe current utilization or outcomes. Our aim was to report current use of intrabronchial valves for air leaks and review outcome data associated with its utilization...

Antibodies (Abs) against major histocompatibility complex (MHC) results in T helper-17 (Th17)-mediated immunity against lung self-antigens (SAgs), K-α1 tubulin and collagen V and obliterative airway disease (OAD). Because B cell-activating transcription factor (BATF) controls Th17 and autoimmunity, we proposed that BATF may play a critical role in OAD. Anti-H2K(b) was administered intrabronchially into Batf (-/-) and C57BL/6 mice. Histopathology of the lungs on days 30 and 45 after Ab administration to Batf (-/-) mice resulted in decreased cellular infiltration, epithelial metaplasia, fibrosis, and obstruction...

There is currently no licensed vaccine that protects foals against Rhodococcus equi-induced pneumonia. Oral administration of live, virulent R. equi to neonatal foals has been demonstrated to protect against subsequent intrabronchial challenge with virulent R. equi. Electron beam (eBeam)-inactivated R. equi are structurally intact and have been demonstrated to be immunogenic when administered orally to neonatal foals. Thus, we investigated whether eBeam inactivated R. equi could protect foals against developing pneumonia after experimental infection with live, virulent R...

BACKGROUND: It remains unclear whether transbronchial lung biopsy (TBLB) is useful for diagnosing Mycobacterium avium complex (MAC) lung disease. METHODS: Thirty-eight consecutive patients with MAC lung disease, who were evaluated with TBLB tissue culture between June 2006 and May 2010, were included. Bronchial washing (BW) and histopathological evaluation were performed in all patients. The positivity rates of BW and TBLB tissue culture, and typical histopathological findings for MAC disease were investigated...

BACKGROUND: The knowledge of the mediastinal lymph node positions from an intrabronchial view was important for conventional transbronchial needle aspiration (TBNA). The introduction of endobronchial ultrasound guided transbronchial needle aspiration (EBUS-TBNA) changed the focus from the intrabronchial landmarks to the real life ultrasound images. However when all EBUS reachable lymph nodes are evaluated (mapping), the knowledge of the intrabronchial positions is crucial. The objective of this study was to present a new expert opinion map from an intrabronchial perspective validated by an interobserver variation analysis...

BACKGROUND: Adverse effects of, and bacterial resistance to, macrolides used to treat Rhodococcus equi infections have prompted search for clinically effective alternative antimicrobials. Liposomal gentamicin (LG) is effective against R. equi in vitro and decreases tissue concentrations of R. equi in experimentally infected mice. Effectiveness of LG treatment of foals with R. equi pneumonia, however, has not been described. HYPOTHESIS: Liposomal gentamicin is safe and effective for treating foals with R...
