Pulmonary mucoepidermoid carcinoma (PMEC) is rare. To date, primary PMEC has not been reported in a child younger than 3 years of age. We report a case of a 2-year-old boy who presented with 3 episodes of wheezing, cough, and fever over a period of 1 month. Radiologic findings were consistent with foreign body aspiration with consequent bronchial obstruction. Bronchoscopy was performed and attempts to retrieve the foreign body resulted in a biopsy of a fleshy lesion. By histology, the lesion was an epithelial neoplasm comprising cells arranged in a nested pattern...

A 56-year-old male who had received transcatheter coil deposition 10 years ago for an arteriovenous malformation (AVM) was admitted to our hospital because of persistent hemosputum. Chest radiograph and bronchoscopy revealed straightened coil bundles in his air way. Recently, less invasive transcatheter intervention has been performed more frequently for treatment of AVM than surgical resection. In our case, however, chest radiography and bronchoscopy showed that the coils might migrate from the deposited site to the airway...

Unidirectional airway valves are devices used for the treatment of persistent air leaks (PALs) secondary to alveolar-pleural fistulas (APF) or bronchopleural fistulas (BPFs). These valves were originally developed as a non-surgical alternative to lung volume reduction surgery (LVRS) for patients with chronic obstructive pulmonary disease (COPD). Randomized trials investigating the use of valves for bronchoscopic LVRS did not lead to the Federal Drug Administration (FDA) approval, but stemming from these studies a Humanitarian Device Exemption (HDE) was granted to Spiration intrabronchial valves (IBVs) for the treatment of PALs...

INTRODUCTION: Surgical resection is usually performed for the treatment of endobronchial tumors. This case describes the use of endoscopic resection as an initial treatment, allowing to spare lung parenchyma. CASE REPORT: A patient was admitted to the emergency unit with right lower lobe pneumonia. A thoracic CT-scan and subsequent bronchoscopy revealed an intrabronchial tumor between the right main and intermediate bronchus. Biopsies were non-diagnostic and a PET-scanner did not find any abnormalities...

Varicella zoster virus (VZV) causes varicella during acute infection and establishes latency in the sensory ganglia. Reactivation of VZV results in herpes zoster, a debilitating and painful disease. It is believed that VZV reactivates due to a decline in cell-mediated immunity; however, the roles that CD4 versus CD8 T cells play in the prevention of herpes zoster remain poorly understood. To address this question, we used a well-characterized model of VZV infection where rhesus macaques are intrabronchially infected with the homologous simian varicella virus (SVV)...

Vanishing lung syndrome is a clinical presentation of giant bullous emphysema associated with significant morbidity and mortality. We present a case of a 50-year-old white woman with vanishing lung syndrome who presented with a spontaneous secondary pneumothorax and an uncontrolled bronchopleural fistula. The large bronchopleural fistula was initially controlled with a double-lumen endotracheal tube and a tube thoracostomy. After surgical efforts failed, complete left lung isolation was performed with multiple intrabronchial valves...

One-way endobronchial valves (EBV) insertion to reduce pulmonary air trapping has been used as therapy for chronic obstructive pulmonary disease (COPD) patients. However, local inflammation may result and can contribute to worsening of clinical status in these patients. We hypothesized that combined EBV insertion and intrabronchial administration of mesenchymal stromal cells (MSCs) would decrease the inflammatory process, thus mitigating EBV complications in severe COPD patients. This initial study sought to investigate the safety of this approach...

We present a rare case of endobronchial hamartoma that required right middle and lower lobectomy. A 59-year-old man presented with cough and sputum lasting for 9 months. Chest X-ray revealed obstructive pneumonia of the right inferior lobe. Chest computed tomography demonstrated an intrabronchial mass lesion, size 12×12 mm, occluding the entrance of the right lower lobe bronchus associated with obstructive pneumonia of the right inferior lobe. Because transbronchial biopsy could not confirm the diagnosis, we performed a right middle and lower lobectomy to diagnose and treat obstructive pneumonia...

Endobronchial carcinoid tumors are the most common intrabronchial tumors in children and adolescents. Common signs and symptoms include persistent cough and wheezing not responsive to bronchodilators, hemoptysis, and recurrent fever. Diagnosis is frequently made by imaging and direct visualization with flexible bronchoscopy; surgery remains the gold standard treatment, and lung-sparing resections should be performed whenever possible. Though carcinoid syndrome-characterized by flushing, palpitations, wheezing, shortness of breath, and diarrhea-has been found in association with adult bronchial carcinoid tumors, to our knowledge only one previous study has reported the presence of carcinoid syndrome in a pediatric patient with an endobronchial carcinoid...

Primary infection with varicella-zoster virus (VZV), a neurotropic alphaherpesvirus, 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. We leveraged this animal model to characterize the host-pathogen interactions in the ganglia during both acute and latent infection by measuring both viral and host transcriptomes on days postinfection (dpi) 3, 7, 10, 14, and 100...

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. 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...
