#1
Yoritake Sakoda, Yojiro Arimori, Masakatsu Ueno, Takafumi Matsumoto
A 39-year-old man treated with dasatinib for chronic myelogenous leukaemia presented to our hospital with haemoptysis, coughing, and dyspnoea. Chest radiography and computed tomography revealed ground-glass opacities and a crazy-paving pattern. Bronchoalveolar lavage was not performed due to serious hypoxemia and bleeding. Significant bleeding from the peripheral bronchi led to a diagnosis of an alveolar haemorrhage. Dasatinib-induced alveolar haemorrhaging was suspected based on the clinical findings. His condition improved immediately after dasatinib withdrawal and initiation of steroid therapy...

REVIEW
Ruza Stevic, Branislava Milenkovic
Tumors of trachea and bronchi are uncommon and can occur in the form of benign or low- and high-grade malignant tumors. Although tracheobronchial tumors (TBTs) represent only 0.6% of all pulmonary tumors, they are clinically significant. Delays in diagnosis of these tumors commonly occur because the signs and symptoms caused by these tumors are nonspecific and chest radiographs are often considered unremarkable. Therefore, novel radiological techniques and better access to flexible bronchoscopy enable detection of larger number of TBT...

The major methods are used to fix or stabilize the central airways and major bronchi with either anterior suspension and/or posterior fixation for severe tracheomalacia (TM). Many support biomaterials, like mesh and sternal plate, can be used in the surgery. But there are no specialized biomaterials for TM which must be casually fabricated by the doctors in operation. Three dimensional printing (3DP) has currently untapped potential to provide custom, protean devices for challenging and life-threatening disease processes...

Allergic bronchopulmonary aspergillosis (ABPA) is a complex hypersensitivity reaction in patients with asthma or cystic fibrosis (CF), which is associated with bronchi colonized by the fungus Aspergillus species, most often Aspergillus fumigatus. ABPA is an important consideration for asthmatics that do not respond to asthma management or with recurrent chest infections and deteriorating lung function in children with cystic fibrosis. We present two cases of non CF bronchiectasis associated with ABPA who presented to our hospital with recurrent hospitalisations of undiagnosed aetiology...

BACKGROUND: Due to absence of visible endobronchial target, the diagnostic yield of flexible bronchoscopy for peribronchial lesions has been unsatisfactory. Convex probe endobronchial ultrasound (CP-EBUS) has allowed for performing real-time transbronchial needle aspiration (TBNA) of enlarged hilar and mediastinal lymph nodes and therefore could also be used as a means of diagnosing proximal peribronchial lesions. METHODS: We retrospectively analyzed the results related to 72 patients who underwent CP-EBUS for peribronchial lesions without endobronchial involvement and adjacent to three-grade bronchi based on chest computed tomography (CT) scan...

Pulmonary tumor thrombotic microangiopathy (PTTM) is a high-mortality disease that is difficult to diagnose clinically. Our patient was an 80-year-old woman who came to us due to symptoms of increasing dyspnea. A clinical evaluation showed that she had hypoxemia and pulmonary arterial hypertension without any abnormalities in the major pulmonary arteries, bronchi, or alveoli. A lung perfusion scan showed multiple wedge-shaped perfusion defects. Further examination revealed adenocarcinoma in her right parotid gland with metastasis to the submandibular lymph nodes...

PURPOSE: Stereotactic body radiation therapy (SBRT) / stereotactic ablative body radiotherapy (SABR) is gaining popularity, but quantitative dose tolerance has still been lacking. To improve this, the April 2016 issue of Seminars in Radiation Oncology will have normal tissue complication probability (NTCP) models for 10 critical structures: optic pathway, cochlea, oral mucosa, esophagus, chestwall, aorta, bronchi, duodenum, small bowel, and spinal cord. METHODS: The project included more than 1500 treatments in 1-5 fractions using CyberKnife, Gamma Knife, or LINAC, with 60 authors from 15 institutions...

Although angiogenesis is a hallmark feature of asthmatic inflammatory responses, therapeutic anti-angiogenesis interventions have received little attention. Objective: Assess the effectiveness of anti-angiogenic Sn2 lipase-labile prodrugs delivered via αvβ3-micellar nanotherapy to suppress microvascular expansion, bronchial remodeling, and airway hyper-responsiveness in Brown Norway rats exposed to serial house dust mite (HDM) inhalation challenges. Results: Anti-neovascular effectiveness of αvβ3-mixed micelles incorporating docetaxel-prodrug (Dxtl-PD) or fumagillin-prodrug (Fum-PD) were shown to robustly suppress neovascular expansion (p<0...

Richard T Carter
The production of echolocation calls in bats along with forces produced by contraction of thoracic musculature used in flight presumably puts relatively high mechanical loads on the lower respiratory tract (LRT). Thus, there are likely adaptations to prevent collapse or distortion of the bronchial tree and trachea during flight in echolocating bats. By clearing and staining (Alcian blue and Alizarin red) LRTs removed from nonvolant neonates, semivolant juveniles, volant subadults, and adult Jamaican fruit bats (Artibeus jamaicensis), I found that calcification of the tracheal, primary bronchial, and secondary bronchial (lobar) cartilage rings occurs over the span of about 3 days and coincides with later developmental stages of flight and the increased production of echolocation calls...

BACKGROUND AND AIM: Mounier-Kuhn syndrome (MKS) is a congenital disorder characterized by tracheobronchomegaly resulting from the absence of elastic fibers in the trachea and main bronchi or atrophy and thinning of the smooth muscle layer. In this syndrome, dead space associated with tracheobronchomegaly increases and discharge of secretions decreases because of ineffective coughing. The most common complications are recurrent lower respiratory tract infections and bronchiectasis. We examined the clinical characteristics, radiological features, and related complications of patients with MKS...

Dilational tracheotomy is a minimally invasive method that can be performed at the bedside on patients requiring long-term mechanical ventilation. In our 70-year-old male patient, percutaneous dilational tracheotomy (Ciaglia Blue Rhino, Cook Medical Inc., Bloomington, Indiana, United States) was performed because of bilateral pneumonia with sepsis. There were no initial problems. Nine days later, while the patient was being repositioned, the tracheal cannula became dislocated. Despite extending the cervical incision it was not possible to recannulate...

Jun Liu, Nana Song, Juan Guardiola, Jesse Roman, Jerry Yu
Sensory units of pulmonary slowly adapting receptors (SARs) are more active in large airways than in small airways. However, there is no explanation for this phenomenon. Although sensory structures in large airways resemble those in small airways, they are bigger and more complex. Possibly, a larger receptor provides greater surface area for depolarization, and thus has a lower activating threshold and/or a higher sensitivity to stretch, leading to more nerve electrical activities. Recently, a single sensory unit has been reported to contain multiple receptors...

It is presented 40-years experience of tracheal adenocystic carcinoma diagnosis and management in 144 patients. Peculiarities of clinical course and choice of diagnostic and therapeutic measures are discussed in relation to stenosis and hypoxia degree and severity of accompanying inflammatory complications of trachea, bronchi and lungs. Technical tools and original methods of resection and reconstruction of trachea and it's bifurcation after extended lung resection are described. Surgical management is carried out in 96 patients: all patients underwent circular resection of trachea (77) or it's bifurcation (19)...

BACKGROUND: To facilitate accurate localization of small lung lesions in thoracoscopic surgery, we employed a micro-radiofrequency identification tag designed to be delivered through the 2-mm working channel of a flexible bronchoscope. This report presents the results of preclinical studies of our novel localizing technique in a canine model. METHODS: To evaluate functional placement, three types of tags [Group A, tag alone (n = 18); Group B, tag + resin anchor (n = 15); and Group C, tag + NiTi coil anchor (n = 15)] were bronchoscopically placed in subpleural areas and subsegmental bronchi via our new delivery device; tags were examined radiographically on days 0-7 and day 14...

BACKGROUND: Damage to extracardiac structures, including the esophagus and phrenic nerve, is a known complication of cryoballoon ablation (CBA) during pulmonary vein (PV) isolation for atrial fibrillation (AF). Other adjacent structures, including the pulmonary bronchi and lung parenchyma, may be affected during CBA at the PV ostia. OBJECTIVE: The purpose of this study was to prospectively study the bronchial effects of CBA in humans undergoing CBA for PV isolation...

The hydrostatic test is used to help determine if there has been a live birth. Computed tomography (CT), with its ability to detect and localize air/gas in the body, offers a rapid, noninvasive tool for assessment.Four baby deaths (20 to 25 weeks' gestation) in which the hydrostatic test, radiographs, and CT were performed before autopsy are presented. In 2 cases, considered stillbirths, the lungs and liver sank, and there was no air seen in the lungs or gas in the liver on CT. Histology of the lungs showed collapsed alveoli...

Occlusion of the bronchial orifices by tissue-like structures is an uncommonly reported finding: it has been referred to as bronchial webs, bronchial synechiae, vanishing bronchus syndrome, or membranous obliterative bronchitis. It differs from bronchiolitis obliterans, a well-described clinical entity that involves smaller airways not visualized on bronchoscopy. Although initially only recognized as a congenital condition, later reports have described it in situations where chronic inflammation results in the irritation of the airways...

Anomalies of the bronchus can be both congenital and acquired. Several different congenital aberrations of the bronchial anatomy are commonly encountered including tracheal bronchus, accessory cardiac bronchus, and bronchial agenesis/aplasia/hypoplasia. In addition, Williams-Campbell syndrome and cystic fibrosis are two other congenital conditions that result in bronchial pathology. Acquired pathology affecting the bronchi can typically be divided into three broad categories of bronchial disease: bronchial wall thickening, dilatation/bronchiectasis, and obstruction/stenosis...

Ichiro Takenaka, Kazuyoshi Aoyama
BACKGROUND: Pulmonary aspiration of gastric contents during tracheal intubation is a life-threatening complication in emergency patients. Rapid sequence intubation is commonly performed to prevent aspiration but is not associated with low risk of intubation related complications. Although it has been considered that aspiration can be prevented in the lateral position, few studies have evaluated the ability to prevent aspiration. Moreover, this position is not always a favorable position for tracheal intubation...

Inflammation is a major burden in respiratory diseases, resulting in airway hyperresponsiveness. Our hypothesis is that resolution of inflammation may represent a long-term solution in preventing human bronchial dysfunctions. The aim of the present study was to assess the anti-inflammatory effects of RvD2, a member of the D-series resolving family, with concomitant effects on ASM mechanical reactivity. The role and mode of action of RvD2 were assessed in an in vitro model of human bronchi under pro-inflammatory conditions, induced either by 1 μM LTD4 or 10 ng/ml TNF-α pre-treatment for 48h...
