    Full Text Available A significant reduction in arterial blood oxygen saturation during fiberoptic bronchoscopy has been proved but it is not yet known whether all patients need supplemental oxygen during this procedure. The aim of study is to examine the relationship between peak expiratory flow rate (PEFR before bronchoscopy and oxygen desaturation during bronchoscopy. Measurement of PEFR (% predicted performed before bronchoscopy and arterial O2 desaturation was assessed with a pulse oximeter during bronchoscopy. Study performed in 66 patients with a median age 53 years, who had been referred to our bronchoscopy unit. None of the patients received supplemental oxygen before the procedure. Thirty nine cases (59% had an episode of O2 desaturation during bronchoscopy. Of them 25 cases (38% had sustained O2 desaturation, requiring oxygen therapy while 14 cases (21% had momentary desaturation (< 20s not requiring O2 therapy. Oxygen therapy was administered in 58% of cases with PEFR % < 60 and in 83% of cases with PEFR % less than 45 (P, 0.008 and 0.001, respectively. We also observed a significant fall in mean O2 saturation during bronchoscopy (88 ± 4 % compared to prebronchoscopy levels (95 ± 2 % (P < 0.0001. It is concluded that PEFR < 60% and especially < 45% is a reliable predictor of hypoxemia and the need to O2 therapy during bronchoscopy.

    Objectives. To describe a technique for removal of sharp aspirated metal objects employing laser through flexible bronchoscopy. Methods. We report two patients in whom a new technique for removal of sharp aspirated metal objects utilizing Nd-Yag laser flexible bronchoscopy was used. Results. Successful and uncomplicated removal of the aspirated thumbpack by flexible bronchoscopy under conscious sedation was accomplished in the two patients described. Both patients were discharged within 24 hours. Conclusions. In patients with aspirated thumbtack laser-assisted breakage of the object through flexible bronchoscopy may obviate the need for rigid bronchoscopy or thoracotomy.

    BACKGROUND: There is significant variation between physicians in terms of how they perform therapeutic bronchoscopy, but there are few data on whether these differences impact effectiveness. METHODS: This was a multicenter registry study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was technical success, defined as reopening the airway lumen to > 50% of normal. Secondary outcomes were dyspnea as measured by the Borg score and health-related quality of life (HRQOL) as measured by the SF-6D. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. Technical success was achieved in 93% of procedures. Center success rates ranged from 90% to 98% (P = .02). Endobronchial obstruction and stent placement were associated with success, whereas American Society of Anesthesiology (ASA) score > 3, renal failure, primary lung cancer, left mainstem disease, and tracheoesophageal fistula were associated with failure. Clinically significant improvements in dyspnea occurred in 90 of 187 patients measured (48%). Greater baseline dyspnea was associated with greater improvements in dyspnea, whereas smoking, having multiple cancers, and lobar obstruction were associated with smaller improvements. Clinically significant improvements in HRQOL occurred in 76 of 183 patients measured (42%). Greater baseline dyspnea was associated with greater improvements in HRQOL, and lobar obstruction was associated with smaller improvements. CONCLUSIONS: Technical success rates were high overall, with the highest success rates associated with stent placement and endobronchial obstruction. Therapeutic bronchoscopy should not be withheld from patients based solely on an assessment of risk, since patients with the most dyspnea and lowest functional status benefitted the most.

    Full Text Available Since the introduction of the flexible fibreoptic bronchoscope in the late 1960s there have been relatively few technological advances for three decades, aside from the development of a white light video bronchoscope with a miniature charge-coupled device built in its tip replacing the fibreoptics. White light flexible videobronchoscopy with its ancillary devices (forceps biopsy, bronchial brushing, bronchoalveolar lavage, bronchial washings and transbronchial needle aspiration has long been the only established diagnostic bronchoscopic technique. With the advances in microtechnology over the past two decades, recent technical developments such as autofluorescence bronchoscopy and endoscopic ultrasound allow better evaluation of endobronchial, mediastinal and parenchymal lesions.

    The study illustrates advantages of Fiberoptic Bronchoscopy, a new service started at St. Luke’s General Hospital in patient care since April 2014. Retrospective review of Bronchoscopies and referrals to Tertiary care unit for Bronchoscopy, prior and after initiation of service at St. Luke’s Hospital were studied. In total, 106 procedures were performed out of which 103(98%) were for diagnostic purpose. Common indications for bronchoscopy were functional airway assessment in 38 cases (35%) of chronic cough, 26 cases (24.8%) of suspected malignancy. The average time taken for procedure was 15 + 1 minute with overall rate of complication recorded in 1 case (0.95%). 32(30%) inpatients were referred before bronchoscopy services were started locally. Fifteen (14%) patients were referred for Endobronchial Ultrasound (EBUS) after diagnostic procedure performed at St. Luke’s Hospital. To conclude, Bronchoscopy is a safe procedure used for diagnosis of various Lung conditions. The services offered locally reduced the time and cost involved in referrals. The diagnostic bronchoscopies performed for malignancy at St. Luke’s Hospital have rightly increased references for EBUS at Tertiary care Unit

    Past work has shown that guidance systems help improve both the navigation through airways and final biopsy of regions of interest via bronchoscopy. We have previously proposed an image-based bronchoscopic guidance system. The system, however, has three issues that arise during navigation: 1) sudden disorienting changes can occur in endoluminal views; 2) more feedback could be afforded during navigation; and 3) the system's graphical user interface (GUI) lacks a convenient interface for smooth navigation between bifurcations. In order to alleviate these issues, we present an improved navigation system. The improvements offer the following: 1) an enhanced visual presentation; 2) smooth navigation; 3) an interface for handling registration errors; and 4) improved bifurcation-point identification. The improved navigation system thus provides significant ergonomic and navigational advantages over the previous system.

    1980-01-01

    An anaesthetic technique for bronchoscopy is described, based on increments of methohexitone given in strict relation to body weight and time, suxamethonium being used to produce relaxation. There was no awareness in the 75 patients studied, while the recovery was rapid and unrelated to the duration of bronchoscopy. The efficacy of small aliquots of lignocaine in reducing injection pain was the same whether given before, or mixed with, the initial methohexitone injection. Other sequelae relating to the anaesthetic technique were minimal. PMID:7241441

    The usual haemodynamic response to fibreoptic bronchoscopy is an increase in heart rate and blood pressure. We therefore compared, in a prospective, randomised, double-blind study, the effect of two doses of oral clonidine premedication (150 microg or 300 microg) with placebo (control group) on the haemodynamic alterations in 62 patients who underwent elective fibreoptic bronchoscopy. Significant increases in blood pressure and heart rate were observed during fibreoptic bronchoscopy only in the control group. Clonidine 150 microg blunted the haemodynamic response to fibreoptic bronchoscopy (p premedicated with 300 microg clonidine. Throughout the study nine patients (75%) in the 300 microg clonidine group were treated at least once for hypotension. Compared with the control group, time to awakening was significantly longer only in patients premedicated with 300 microg clonidine. In conclusion, premedication with 150 microg oral clonidine attenuates haemodynamic responses to fibreoptic bronchoscopy, without causing excessive haemodynamic depression and sedation. These data encourage the administration of clonidine as premedication in patients undergoing fibreoptic bronchoscopy, particularly in those with, or at risk for, coronary artery disease.

    Full Text Available OBJECTIVE: To evaluate the importance of flexible bronchoscopy in tracheostomy patients in the process of decannulation to assess the incidence and types of laryngotracheal injury and compare the presence of such lesions with clinical criteria used for decannulation. METHODS: We studied 51 tracheostomized patients aged between 19 and 87 years, with tracheal stent for a mean of 46 ± 28 days and with clinical criteria for decannulation. They were submitted to tracheostomy tube occlusion tolerance testfor 24 hours, and then to flexible bronchoscopy. We described and classified the diagnosed laryngotracheal changes. We compared the clinical criteria for decannulation indication with the bronchoscopy-diagnosed laryngotracheal injuries that contraindicated decannulation. We identified the factors that could interfere in decannulation and evaluated the importance of bronchoscopy as part of the process. RESULTS: Forty (80.4% patients had laryngotracheal alterations. Of the 40 patients considered clinically fit to decannulation, eight (20% (p = 0.0007 presented with laryngotracheal injuries at bronchoscopy that contraindicated the procedure. The most frequent laryngeal alteration was vocal cords lesion, in 15 (29% individuals, and granuloma, the most prevalent tracheal lesion, in 14 (27.5% patients. CONCLUSION: flexible bronchoscopy showed a large number of laryngotracheal injuries, the most frequent being the vocal cords injury in the larynx and the granuloma in the trachea, which contributed to increase the decannulation procedure safety.

    To evaluate the feasibility of and the potential for using optical coherence tomography in conjunction with conventional bronchoscopy in the evaluation of the airways. Methods: This was a pilot study based on an ex vivo experimental model involving three animals: one adult New Zealand rabbit and two Landrace pigs. An optical coherence tomography imaging catheter was inserted through the working channel of a flexible bronchoscope in order to reach the distal trachea of the animals. Images of the walls of the trachea were systematically taken along its entire length, from the distal to the proximal portion. Results: The imaging catheter was easily adapted to the working channel of the bronchoscope. High-resolution images of cross sections of the trachea were taken in real time, precisely delineating microstructures, such as the epithelium, submucosa, and cartilage, as well as the adventitia of the anterior and lateral tracheal walls. The corresponding layers of the epithelium, mucosa, and cartilage were clearly differentiated. The mucosa, submucosa, and trachealis muscle were clearly identified in the posterior wall. Conclusions: It is feasible to use an optical coherence tomography imaging catheter in combination with a flexible bronchoscope. Optical coherence tomography produces high resolution images that reveal the microanatomy of the trachea, including structures that are typically seen only on images produced by conventional histology.

    2015-12-01

    Bronchoscopy is a commonly used minimally invasive procedure for lung-cancer staging. In standard practice, however, physicians differ greatly in their levels of performance. To address this concern, image-guided intervention (IGI) systems have been devised to improve procedure success. Current IGI bronchoscopy systems based on virtual bronchoscopic navigation (VBN), however, require involvement from the attending technician. This lessens physician control and hinders the overall acceptance of such systems. We propose a hands-free VBN system for planning and guiding bronchoscopy. The system introduces two major contributions. First, it incorporates a new procedure-planning method that automatically computes airway navigation plans conforming to the physician's bronchoscopy training and manual dexterity. Second, it incorporates a guidance strategy for bronchoscope navigation that enables user-friendly system control via a foot switch, coupled with a novel position-verification mechanism. Phantom studies verified that the system enables smooth operation under physician control, while also enabling faster navigation than an existing technician-assisted VBN system. In a clinical human study, we noted a 97% bronchoscopy navigation success rate, in line with existing VBN systems, and a mean guidance time per diagnostic site = 52 s. This represents a guidance time often nearly 3 min faster per diagnostic site than guidance times reported for other technician-assisted VBN systems. Finally, an ergonomic study further asserts the system's acceptability to the physician and long-term potential.

    From October 1991 through April 1992, 16 infants aged 5 to 25 months (mean age 14.3 months) underwent bronchoscopy with a flexible fiberoptic bronchoscope, under local anesthesia. The technique is described in detail. Reasons for bronchoscopy included recurrent or persistent pneumonia (n = 4), persistent atelectasia (n = 4), lymphadenopathy and/or airway compression (n = 2), suspected foreign body (n = 2), bronchoalveolar lavage to investigate diffuse interstitial lung disease (n = 2), and severe recurrent wheezing (n = 2). The procedure established the accurate diagnosis in 14 cases. Adverse events (32%) were minor (transient hypoxia, n = 3; moderate fever, n = 1; and laryngospasm, n = 1) and resolved completely. Flexible fiberoptic bronchoscopy under local anesthesia is a simple procedure which is safe in patients under 30 months of age when performed by a experienced operator in an adequate facility. This method is useful for the diagnosis and/or treatment of a broad spectrum of conditions.

    During hospital bronchoscopy examinations, aerosols emitted from the patient's during coughing can be found suspended in the ambient air. The aerosols can contain pathogenic microorganisms. Depending on their size, these microorganisms can remain in the air for a long time. The objective of this study was to measure the sizes and concentrations of the biological and non-biological particles produced during bronchoscopy examinations, and to propose preventive or corrective measures. Two bronchoscopy rooms were studied. An aerodynamic particle sizer (UV-APS) was used to establish the concentrations of the particles present and their size distributions. This instrument determines the aerodynamic diameter of the aerosols and can distinguish fluorescent (bioaerosols) and non-fluorescent particles. Reference concentrations were measured before the start of the examinations (morning background concentrations). They were used as comparison levels for the concentrations measured during and at the end of the bronchoscopies. In parallel, computational fluid dynamics (CFD) made it possible to isolate and understand different factors that can affect the concentration levels in bronchoscopy rooms. The concentrations of the non-fluorescent and fluorescent particles (bioaerosols) were significantly higher (p ≤ 0.05) during the bronchoscopy examinations than the reference concentrations. For the investigated factors, the bioaerosol concentrations were significantly higher during bronchoscope insertion tasks. The time required at the end of the day for the bioaerosols to reach the morning reference concentrations was about fifteen minutes. The average particle sizes were 2.9 μm for the fluorescent particles (bioaerosols) and 0.9 μm for the non-fluorescent particles. Our models based on computational fluid dynamics (CFD) enabled us to observe the behaviour of aerosols for the different rooms.

    These guidelines on flexible bronchoscopy depict important clues to be known and taken into account while practicing flexible bronchoscopy, in adult, except in emergency situations. This is a practical clarification. Safety conditions, complications, anesthesia, infectious risks, cleaning and disinfection are detailed from a review of the literature. Intensive care practice of bronchoscopy requires more attention due to higher risks patients and is discussed extensively. Standards and performances of the various sampling techniques complete this work. Indications for bronchoscopy, therapeutic and paediatric bronchoscopy are not covered in these guidelines.

  1. Giant endobronchial hamartoma resected by fiberoptic bronchoscopy electrosurgical snaring

    Full Text Available Abstract Less than 1% of lung neoplasms are represented by benign tumors. Among these, hamartomas are the most common with an incidence between 0.025% and 0.32%. In relation to the localization, hamartomas are divided into intraparenchymal and endobronchial. Clinical manifestation of an endobronchial hamartoma (EH results from tracheobronchial obstruction or bleeding. Usually, EH localizes in large diameter bronchus. Endoscopic removal is usually recommended. Bronchotomy or parenchimal resection through thoracotomy should be reserved only for cases where the hamatoma cannot be approached through endoscopy, or when irreversible lung functional impairment occurred after prolonged airflow obstruction. Generally, when endoscopic approach is used, this is through rigid bronchoscopy, laser photocoagulation or mechanical resection. Here we present a giant EH occasionally diagnosed and treated by fiberoptic bronchoscopy electrosurgical snaring.

    BACKGROUND: There are significant variations in how therapeutic bronchoscopy for malignant airway obstruction is performed. Relatively few studies have compared how these approaches affect the incidence of complications. METHODS: We used the American College of Chest Physicians (CHEST) Quality Improvement Registry, Evaluation, and Education (AQuIRE) program registry to conduct a multicenter study of patients undergoing therapeutic bronchoscopy for malignant central airway obstruction. The primary outcome was the incidence of complications. Secondary outcomes were incidence of bleeding, hypoxemia, respiratory failure, adverse events, escalation in level of care, and 30-day mortality. RESULTS: Fifteen centers performed 1,115 procedures on 947 patients. There were significant differences among centers in the type of anesthesia (moderate vs deep or general anesthesia, P 3, redo therapeutic bronchoscopy, and moderate sedation. The 30-day mortality was 14.8%; mortality varied among centers (range, 7.7%-20.2%, P = .02). Risk factors for 30-day mortality included Zubrod score > 1, ASA score > 3, intrinsic or mixed obstruction, and stent placement. CONCLUSIONS: Use of moderate sedation and stents varies significantly among centers. These factors are associated with increased complications and 30-day mortality, respectively. PMID:25741903

    Foreign body (FB) inhalation in the tracheobronchial tree is an infrequently encountered event in adults. The diagnosis is suspected in the presence of a clinical history of aspiration and the presence of respiratory symptoms. Management involves confirmation by flexible bronchoscopy, which may be both diagnostic as well as therapeutic. However, in certain situations including those with large FB, FB embedded in granulation tissue or FB with very smooth margins, rigid bronchoscopy may be superior to flexible bronchoscopy in the retrieval of the FB. An alternative to rigid bronchoscopy in such situations may be the use of a cryoprobe. Herein, we describe a patient with a large tracheobronchial FB causing a complete collapse of the left lung and hypoxemia. The FB was successfully extracted using a cryoprobe during flexible bronchoscopy, obviating the need for rigid bronchoscopy.

    Broncholithiasis is the presence of calcific material within the tracheobronchial tree. Asymptomatic patients can be managed with observation only, whereas symptomatic disease requires surgery, rigid or flexible bronchoscopic removal. Recent reports have shown that flexible bronchoscopy can be a safe and effective option for removal of loose in addition to partially imbedded broncholiths. We present a case of a 65-yearold man with chronic cough that underwent successful cryotherapy assisted bronchoscopic removal of an imbedded broncholith. We will also review current literature regarding the management broncholithiasis.

    The aim of this study was to demonstrate the possibilities, advantages and limitations of virtual bronchoscopy using data sets from positron emission tomography (PET) and computed tomography (CT). Twelve consecutive patients with lung cancer underwent PET/CT. PET was performed with F-18-labelled 2-[fluorine-18]-fluoro-2-deoxy-D-glucose ({sup 18}F-FDG). The tracheobronchial system was segmented with a volume-growing algorithm, using the CT data sets, and visualized with a shaded-surface rendering method. The primary tumours and the lymph node metastases were segmented for virtual CT-bronchoscopy using the CT data set and for virtual PET/CT-bronchoscopy using the PET/CT data set. Virtual CT-bronchoscopy using the low-dose or diagnostic CT facilitates the detection of anatomical/morphological structure changes of the tracheobronchial system. Virtual PET/CT-bronchoscopy was superior to virtual CT-bronchoscopy in the detection of lymph node metastases (P=0.001), because it uses the CT information and the molecular/metabolic information from PET. Virtual PET/CT-bronchoscopy with a transparent colour-coded shaded-surface rendering model is expected to improve the diagnostic accuracy of identification and characterization of malignancies, assessment of tumour staging, differentiation of viable tumour tissue from atelectases and scars, verification of infections, evaluation of therapeutic response and detection of an early stage of recurrence that is not detectable or is misjudged in comparison with virtual CT-bronchoscopy.

    Full Text Available To evaluate the occurrence of electrocardiographic abnormalities during fiberoptic bronchoscopy, in relation to specific stages of the procedures, patients′ age, sex, smoking, pre-existing lung disease, premedication and oxygen saturation, a prospective study was conducted on 56 patients aged 35 to 75 (mean 62 years without pre-existing cardiovascular disease. Patients were connected to a 12-lead computerized electrocardiographic recorder and pulse oximeter. Fall of oxygen saturation from mean of 95.12% before the procedure to below 80% was observed in 12 (21.4% patients and below 75% in 5 (8.9% patients, at various stages. Statistically highly significant (p < 0.001 fall of oxygen saturation was observed during the procedures while bronchoscope was introduced into the airways and tracheobronchial tree examined. Major disturbances of cardiac rhythm (i.e. atrial, ventricular or both developed in 23 (41.07% patients. Out of these, sinus tachycardia was noted in 16 (69.5%, ventricular premature complexes in 5 (21.7% and paroxysmal supraventricular tachycardia in 2 (8.6% patients. Arrhythmias were most frequent in association with periods of maximum oxygen desaturation in 18 (78.2% of these 23 patients. Oxygen desaturation persisted for more than half an hour in 38 (67.8% of the 56 patients. However, no correlation was observed between the frequency of arrhythmias during bronchoscopy and patients′ age, sex pre-medication or pre-existing pulmonary disease.

    Full Text Available Aspiration of the lower airways due to foreign body is rare in adults. This study aimed to determine the outcome of patients who received flexible bronchoscopy with different modalities for foreign body removal in the lower airways.Between January 2003 and January 2014, 94 patients diagnosed with foreign body in the lower airways underwent flexible bronchoscopy with different modalities, which included forceps, loop, basket, knife, electromagnet, and cryotherapy. The clinical presentation, foreign body location and characteristics, and applications of flexible bronchoscopy were analyzed.Forty (43% patients had acute aspiration, which developed within one week of foreign body entry and 54 (57% had chronic aspiration. The most common foreign bodies were teeth or bone. More patients with chronic aspiration than those with acute aspiration were referred from the out-patient clinic (48% vs. 28%, but more patients with acute aspiration were referred from the emergency room (35% vs. 6% and intensive care unit (18% vs. 2%. Flexible bronchoscopy with different modalities was used to remove the foreign bodies (85/94, 90%. Electromagnet or cryotherapy was used in nine patients to eliminate the surrounding granulation tissue before foreign body removal. In the nine patients with failed flexible bronchoscopy, eight underwent rigid bronchoscopy instead and one had right lower lung lobectomy for lung abscess.Flexible bronchoscopy with multiple modalities is effective for diagnosing and removing foreign bodies in the lower respiratory airways in adults, with a high success rate (90% and no difference between acute and chronic aspirations.

    Full Text Available Abstract Introduction Methemoglobinemia is a rare cause of hypoxemia, characterized by abnormal levels of oxidized hemoglobin that cannot bind to and transport oxygen. Case presentation A 62-year-old male underwent bronchoscopy where lidocaine oral solution and Hurricaine spray (20% benzocaine were used. He developed central cyanosis and his oxygen saturation was 85% via pulse oximetry. An arterial blood gas revealed pH 7.45, PCO2 42, PO2 282, oxygen saturation 85%. Co-oximetry performed revealed a methemoglobin level of 17.5% (normal 0.6–2.5%. The patient was continued on 15 L/minute nonrebreathing face mask and subsequent oxygen saturation improved to 92% within two hours. With hemodynamic stability and improved SpO2, treatment with methylene blue was withheld. Conclusion Methemoglobinemia is a potentially lethal condition after exposure to routinely used drugs. Physicians should be aware of this complication for early diagnosis and treatment.

    2015-09-01

    Full Text Available Tracheal or bronchial proximal stenoses occur as complications in 20–30% of lung cancers, resulting in a dramatic alteration in quality of life and poor prognosis. Bronchoscopic management of these obstructions is based on what are known as “thermal” techniques for intraluminal stenosis and/or placement of tracheal or bronchial prostheses for extrinsic compressions, leading to rapid symptom palliation in the vast majority of patients. This invasive treatment should only be used in cases of symptomatic obstructions and in the presence of viable bronchial tree and downstream parenchyma. This review aims to clarify 1 the available methods for assessing the characteristics of stenoses before treatment, 2 the various techniques available including their preferred indications, outcomes and complications, and 3 the integration of interventional bronchoscopy in the multidisciplinary management of proximal bronchial cancers and its synergistic effects with the other specific treatments (surgery, radiotherapy or chemotherapy.

    Full Text Available Aim: In this study, we aimed to investigate the effect of written informed consent and comprehensive multimedia information on the anxiety level of patients, consumption of sedatives, difficulties during bronchoscopy, complications and duration of procedure. Methods: 150 patients undergoing bronchoscopy were included to this study. They were randomized into two groups Multimedia information group (MIG, n = 75 and written-informed consent group (WICG, n = 75. Signed written informed consent was obtained from all patients. Patients in MIG group watched comprehensive multimedia presentation. State anxiety scores of all patients were evaluated with State and Trait anxiety inventory (STAI-S. Results: STAI-S score of patients in MIG (40.31 ± 8.08 was lower than patients in WICG (44.29 ± 9.62 (P = 0.007. Satisfaction level was higher in MIG (P = 0.001. Statistically higher difficulties during "passage through vocal cords" and "interventions during bronchoscopy" were present in WICG group (P = 0.013 and P = 0.043, respectively. Total midazolam dose during bronchoscopy, and duration of bronchoscopy were statistically lower in MIG patients (P < 0.001 and P = 0.045, respectively. Difficulties during "waiting period", "passage through nasal/oral route", "applications of local anesthesia" and "complication frequency" were similar in both groups. Conclusion: Besides reducing the state anxiety, multimedia information can reduce the dose of sedation, shorten the processing duration and reduce the difficulties during bronchoscopy.

    Full Text Available Background and Aim: Rigid bronchoscopy is often an indispensable procedure in the therapeutic management of a wide variety of tracheobronchial disorders. However, it is performed at only a few centers in adult patients in India. Herein, we report our initial 1-year experience with this procedure. Materials and Methods: A prospective observational study on the indications, outcomes, and safety of various rigid bronchoscopy procedures performed between November 2009 and October 2010. Improvement in dyspnea, cough, and the overall quality of life was recorded on a visual analog scale from 0 to 100 mm. A systematic review of PubMed was performed to identify studies reporting the use of rigid bronchoscopy from India. Results: Thirty-eight rigid bronchoscopies (50 procedures were performed in 19 patients during the study period. The commonest indication was benign tracheal stenosis followed by central airway tumor, and the procedures performed were rigid bronchoplasty, tumor debulking, and stent placement. The median procedure duration was 45 (range, 30-65 min. There was significant improvement in quality of life associated with therapeutic rigid bronchoscopy. Minor procedural complications were encountered in 18 bronchoscopies, and there was no procedural mortality. The systematic review identified 15 studies, all on the role of rigid bronchoscopy in foreign body removal. Conclusions: Rigid bronchoscopy is a safe and effective modality for treatment of a variety of tracheobronchial disorders. There is a dire need of rigid bronchoscopy training at teaching hospitals in India.

    The availability of newer, more sophisticated and versatile bronchoscopes has expanded the spectrum and scope of the indications for bronchoscopy in the newborn infant both for diagnostic and therapeutic purposes. The aim of this study was to carry out a retrospective analysis of the bronchoscopies performed on newborn infants, and to review the indications of this procedure in this age group. Sixty-three patients were submitted to 67 bronchoscopies in a period of 13 years, allowing the diagnosis of 45 anomalies and malformations of the tracheo-bronchial tree, and the performance of 24 bronchoalveolar lavages. In six cases, endoscopic removal of secretions helped to resolve resistant atelectasia, while in another case, with esophageal atresia, intra-operative definition of the fistula tract was possible through catheterisation of the fistula with the bronchoscope. The flexible bronchoscope was preferred for diagnosis by direct visualisation, and the rigid bronchoscope for some diagnostic and therapeutic procedures. Stridor, unexplained cyanosis, hemoptysis, persistent or recurrent pulmonary images, difficulties in the intubation or extubation, and persistent disturbances in ventilation are among the main indications for bronchoscopy in the newborn infant. Bronchoscopy also allows the performance of subsidiary techniques, such as bronchoalveolar lavage, biopsy and laser therapy.

    Full Text Available Background : Diagnosis of sputum/smear-negative pulmonary tuberculosis patients can be both challenging and time consuming with many patients being put on empirical anti-tubercular treatment. Fibreoptic bronchoscopy may provide a confirmative and early diagnosis in such patients. Aims: To assess the role of fibreoptic bronchoscopy in the diagnosis of sputum /smear-negative pulmonary tuberculosis. Materials and Methods: The study was conducted on 75 suspected sputum / smear-negative pulmonary tuberculosis cases attending Pulmonary Medicine Department of Mamata Medical College and Hospital, Khammam, AP. Fibreoptic bronchoscopy was performed; culture of sputum and bronchial washings for Mycobacterium tuberculosis was done by BACTEC method. Results: A final diagnosis of sputum /smear-negative pulmonary tuberculosis was made in 60 patients. Bronchial washings smear for acid-fast bacilli (AFB was positive in 21 patients while culture of bronchial washings was positive in 39 patients. In 29 patients, smear or culture of bronchial washing alone contributed to the final diagnosis. Total yield of bronchoscopy in diagnosis of sputum smear negative pulmonary tuberculosis was 83.33% (50/60; bronchoscopy was the only diagnostic method in 66% cases (40/60 with bronchial washings being the only diagnostic method in 48.33%. Bronchial washings smear for AFB and histopathological evidence of caseating granuloma made immediate diagnosis possible in 48.33% (29/60 patients. Conclusion: Our study suggests that fibreoptic bronchoscopy can provide excellent material for diagnosis of suspected cases of Pulmonary Tuberculosis in whom smears of expectorated sputum do not reveal mycobacteria.

    A 62-year-old man with a chronic cough presented with atelectasis of the left upper lobe on chest X-ray. Chest computed tomography showed an atelectasis in the left upper lobe with bronchial wall thickening, stenosis, dilatation, and mucoid impaction. We performed bronchoscopy and found a well-circumscribed mass on the left upper lobe bronchus. The mass was removed by flexible bronchoscopy using an electrosurgical snare and diagnosed with lipoma. An endobronchial lipoma is a rare benign tumor that can be treated by a surgical or endoscopic approach. We report the successful removal of endobronchial lipoma via flexible bronchoscopic electrosurgical snare.

    A crucial step for successful percutaneous tracheostomy is the introduction of the needle and guide wire into the trachea. Capnography has recently been proposed as one way to confirm tracheal needle placement. In this randomised controlled study, we used capnography in 26 patients and bronchoscopy in 29 patients to confirm needle placement for percutaneous tracheostomy using Blue Rhino kit. The operating times and the incidence of peri-operative complications were similar for both groups. Capnography proved to be as effective as bronchoscopy in confirming correct needle placement.

    Three patients suffering from severe, chronic, bronchial asthma underwent bronchoscopy and lavage, using in the irrigant fluid acetylcysteine, isoetharine and Solu-Medrol. All patients had a large amount of thick mucus in the tracheobronchial tree which was removed during the lavage. Following the lavage, all three patients were easily treated with conventional allergic measures and were able to lead normal lives, which they could not do before. A discussion of the precautions to be taken by the medical-surgical team in charge of a patient undergoing bronchoscopy and lavage is made. These conclusions were based on the results of two previous reports by the authors in addition to the present communication.

    Full Text Available Background. Conventional flexible bronchoscopy has limited sensitivity in the diagnosis of peripheral lung lesions and is dependent on lesion size. However, advancement of CT imaging offers multiplanar reconstruction facilitating enhanced preprocedure planning. This study aims to report efficacy and safety while considering the impact of patient selection and multiplanar CT planning. Method. Prospective case series of patients with peripheral lung lesions suspected of having lung cancer who underwent flexible bronchoscopy (forceps biopsy and lavage. Endobronchial lesions were excluded. Patients with negative results underwent CT-guided transthoracic needle aspiration, surgical biopsy, or clinical-radiological surveillance to establish the final diagnosis. Results. 226 patients were analysed. The diagnostic yield of bronchoscopy was 80.1% (181/226 with a sensitivity of 84.2% and specificity of 100%. In patients with a positive CT-Bronchus sign, the diagnostic yield was 82.4% compared to 72.8% with negative CT-Bronchus sign (p=0.116. Diagnostic yield was 84.9% in lesions > 20 mm and 63.0% in lesions ≤ 20 mm (p=0.001. Six (2.7% patients had transient hypoxia and 2 (0.9% had pneumothorax. There were no serious adverse events. Conclusion. Flexible bronchoscopy with appropriate patient selection and preprocedure planning is more efficacious in obtaining a diagnosis in peripheral lung lesions compared to historical data. This trial is registered with ClinicalTrials.gov Identifier: NCT01374542.

    The objective of this study is to investigate the effects of full airway drainage by fiber bronchoscopy through artificial airway in the treatment of traumatic atelectasis with occult manifestations. From May 2006 to May 2011, 40 cases of occult traumatic atelectasis were enrolled into our prospective study. Group A (n = 18) received drainage by nasal bronchoscope; group B underwent airway drainage by fiber bronchoscopy through artificial airway (n = 22). The effects of treatment were evaluated by the incidence of adult respiratory distress syndrome (ARDS), lung abscess, and the average length of hospital stay. Compared with nasal fiber-optic treatment, airway drainage by fiber bronchoscopy through artificial airway reduced the incidence of ARDS (p = 0.013) and lung abscess (p = 0.062) and shortened the mean length of stay (p = 0.018). Making the decision to create an artificial airway timely and carry out lung lavage by fiber bronchoscopy through artificial airway played a significant role in the treatment of occult traumatic atelectasis.

    Fiber bronchoscopy under local anaesthesia is an examination procedure frequently employed in the remainder of Scandinavia, Europe and USA. It requires only few resources and the costs are considerably less than fiber bronchoscopy under general anaesthesia. Bronchoalveolar lavage (BAL) in connection with fiber bronchoscopy is rapidly undertaken but analysis of the material obtained requires considerable time. A method of induction of local anaesthesia, performance of BAL and preparation of the washings obtained is described. Fiber bronchoscopy and BAL are considered to be safe examination procedures in patients with mild asthma in a stable phase. The examination is only associated with slight discomfort for the patients, who will frequently accept repeated investigations, and complications are rare. BAL is a valuable examination procedure in research and the results have increased the knowledge of mechanisms in a series of interstitial pulmonary diseases. Future investigations of the humoral and cellular components in BAL fluid in asthmatic patients will contribute to increase knowledge of the pathological mechanisms in asthmatic disease.

    Full Text Available In diagnosing the aspiration of the foreign body (AFB in children most important are: medical history, clinical signs and positive radiography of the lungs. Common dilemmas in the diff erential diagnosis are life-threatening asthma attacks or difficult pneumonia. Conventional rigid bronchoscopy (RB is not recommended as a routine method. Virtual bronchoscopy (VB can be a diagnostic tool for solving dilemmas. Fiber-optic bronchoscopy (FOB has a therapeutic stake in severe cases. Herein, we describe a girl, at the age of 6, who was hospitalized due to rapid bronchoconstriction and based on the anamnesis, clinical symptoms and physical fi ndings the suspicion was that she aspirated the foreign body. Due to the poor general condition and possible sequel, the idea of RB was dropped out. Multidetector computed tomography of the chest and VB was performed and AFB was not found. Due to positive epidemiological situation, virus H1N1 was excluded. FOB established that the foreign body does not exist in the airways. During bronchoscopy numerous castings are aspirated from the peripheral airways which lead to faster final recovery. With additional procedures, the diagnosis of asthma was confirmed and for girl that was the first attack. Along with inhaled corticosteroids as prevention she feels well.

    Full Text Available Background: Because of airway stimulations during the bronchoscopy and lack of direct access to the airway, preferred method of anesthesia for rigid bronchoscopy is already controversial. In this study we compared inhalation anesthesia with total intravenous anesthesia (TIVA for rigid bronchoscopy. Method and Materials: 30 patients aged 2-6 years were chosen divided on two same groups. Anesthesia in group I maintained with halothane and in group II maintained with remifentanil and propofol. Oxygenation, heart rate, respiratory rate, coughing, bucking, laryngospasm, bronchospasm were evaluated during and after surgery. Also Operation success and surgeon’s satisfaction were recorded as well.Results: Demographic findings were the same in both groups. Oxygenation and heart rate were more stable in group II (P=0.047 and P=0.026 respectively but there was no significant difference in respiratory rate between two groups (P=1. Success rate was also similar in both groups but surgeon’s satisfaction was significantly higher in TIVA (P=0.003. There was not any significant different between complications in two groups. Conclusion: We suggest TIVA for rigid bronchoscopy because of better oxygenation, more homodynamic stability, surgeon’s satisfaction, lack of air pollution and less interference with surgeon’s visual field.

    Full Text Available During bronchoscopy hypoxemia is commonly found and oxygen supply can be delivered by interfaces fed with high gas flows. Recently, the high-flow nasal cannula (HFNC has been introduced for oxygen therapy in adults, but they have not been used so far during bronchoscopy in adults. Forty-five patients were randomly assigned to 3 groups receiving oxygen: 40 L/min through a Venturi mask (V40, N=15, nasal cannula (N40, N=15, and 60 L/min through a nasal cannula (N60, N=15 during bronchoscopy. Gas exchange and circulatory variables were sampled before (FiO2 = 0.21, at the end of bronchoscopy (FiO2 = 0.5, and thereafter (V40, FiO2 = 0.35. In 8 healthy volunteers oxygen was randomly delivered according to V40, N40, and N60 settings, and airway pressure was measured. At the end of bronchoscopy, N60 presented higher PaO2, PaO2/FiO2, and SpO2 than V40 and N40 that did not differ between them. In the volunteers (N60 median airway pressure amounted to 3.6 cmH2O. Under a flow rate of 40 L/min both the Venturi mask and HFNC behaved similarly, but nasal cannula associated with a 60 L/min flow produced the better results, thus indicating its use in mild respiratory dysfunctions.

    Recently, ultra-thin bronchoscopy has made it possible to observe smaller bronchi not visualized using standard techniques. We describe a case of pulmonary mucormycosis with cavitation, diagnosed using an ultra-thin bronchoscope. A 15-year-old girl with acute myeloid leukaemia had taken oral prednisolone, 60 mg/day, for graft versus host disease after haematopoietic stem cell transplantation. She was admitted to our hospital with fever and a large cavitary lesion in the right hilum. Using an ultra-thin bronchoscope, the interior of the cavity in the superior segment of the right lower lobe was observed. The bronchoscopic findings revealed debris adhering to the cavity wall with a small volume of effusion. Cunninghamella bertholletiae was isolated from the effusion specimen obtained using the bronchoscope. Pulmonary mucormycosis (C. bertholletiae) complicating an immunocompromised state was diagnosed. Ultra-thin bronchoscopy is useful to diagnose complex pulmonary infections and more research is needed to verify its clinical indications and utility.

    A vital task in the planning of peripheral bronchoscopy is the segmentation of the airway tree from a 3-D multidetector computed tomography chest scan. Unfortunately, existing methods typically do not sufficiently extract the necessary peripheral airways needed to plan a procedure. We present a robust method that draws upon both local and global information. The method begins with a conservative segmentation of the major airways. Follow-on stages then exhaustively search for additional candidate airway locations. Finally, a graph-based optimization method counterbalances both the benefit and cost of retaining candidate airway locations for the final segmentation. Results demonstrate that the proposed method typically extracts 2-3 more generations of airways than several other methods, and that the extracted airway trees enable image-guided bronchoscopy deeper into the human lung periphery than past studies.

    Conclusion: Routine flexible bronchoscopy technique has a reasonably high diagnostic yield in current clinical practice. Our study concludes that the diagnostic yield of FOB at our rural setting is comparable with the studies from other centres within the country and abroad. The procedure is more useful in diagnosis when combined with a sound clinical judgment and other supportive investigations. [Natl J Med Res 2013; 3(4.000: 392-395

    Lung cancer is the leading cause of cancer-related deaths worldwide with an overall 5-year survival rate of 17% after diagnoses. Indeed many patients tend to have a very poor prognosis, due to being diagnosed at an advanced stage. Conversely patients who are diagnosed at an early stage have a 5-year survival >70%, indicating that early detection of lung cancer is crucial to improve survival. Although flexible bronchoscopy is a relatively non-invasive procedure for patients suspected of having lung cancer, only 29% of carcinoma in situ (CIS) and 69% of microinvasive tumors were detectable using white light bronchoscopy (WLB) alone. As a result, in the past two decades, new bronchoscopic techniques have been developed to increase the yield and diagnostic accuracy, such as autofluorescence bronchoscopy (AFB), narrow band imaging (NBI) and high magnification bronchovideoscopy (HMB). However, due to the low specificity and the limitation to detect only proximal bronchial tree, new probe-based technologies have been introduced: radial endobronchial ultrasound (R-EBUS), optical coherence tomography (OCT), confocal laser endomicroscopy (CLE) and laser Raman spectroscopy (LRS). To date, although tissue biopsy remains the gold standard for diagnosing malignant/premalignant airway disease and some techniques are still investigational, bronchoscopic technologies can be considered the safest and most accurate tools to evaluate both central and distal airway mucosa.

    Full Text Available Luis M Seijo Pulmonary Department, Instituto de Investigación Sanitaria-Fundación Jimenez Díaz-Centro de Investigación Biomedica en Red Enfermedades Respiratorias, Madrid, Spain Abstract: Electromagnetic navigation bronchoscopy (ENB is one of several technological advances which have broadened the indications for bronchoscopy in the diagnostic workup of lung cancer. The technique facilitates bronchoscopic sampling of peripheral pulmonary nodules as well as mediastinal lymph nodes, although wide availability and expertise in endobronchial ultrasonography has limited its application in routine clinical practice to the former. ENB in this setting is quite versatile and may be considered an established alternative to more invasive techniques, especially in selected patients with underlying pulmonary disease or comorbidities at high risk for complications from computer topography-guided fine needle aspiration or surgical resection. Nodule sampling may be performed with a variety of instruments, including forceps, cytology brushes, and transbronchial needles. Although samples are generally small, they are often suitable for molecular analysis. Keywords: lung cancer, ENB, electromagnetic navigation, bronchoscopy, diagnosis, pulmonary nodule

    Full Text Available ABSTRACTINTRODUCTION:Flexible fiber optic bronchoscopy is a valuable intervention for evaluation and management of respiratory diseases in both infants, pediatric and adult patients. The aim of this study is to investigate the influence of the airway supporting maneuvers on glottis view during pediatric flexible fiberoptic bronchoscopy.MATERIALS AND METHODS:In this randomized, controlled, crossover study; patients aged between 0 and 15 years who underwent flexible fiberoptic bronchoscopy procedure having American Society of Anesthesiologists I---II risk score were included. Patients having risk of difficult intubation, intubated or patients with tracheostomy, and patients with reduced neck mobility or having cautions for neck mobility were excluded from this study. After obtaining best glottic view at the neutral position, patients were positioned jaw trust with open mouth, jaw trust with teeth prottution, head tilt chin lift and triple airway maneuvers and best glottis scores were recorded.RESULTS:Total of 121 pediatric patients, 57 girls and 64 boys, were included in this study. Both jaw trust with open mouth and jaw trust with teeth prottution maneuvers improved the glottis view compared with neutral position (p 0.05. Head tilt chin lift and triple airway maneuvers improved glottis view when compared with both jaw trust with open mouth and jaw trust with teeth prottution maneuvers and neutral position (p 0.05.

    In the event of a high degree of airway obstruction, endotracheal intubation can be impossible and even dangerous, because it can cause complete airway obstruction, especially in patients with high tracheal lesions. However, a smaller endotracheal tube under the guidance of a bronchoscope can be insinuated past obstructive tumor in most noncircumferential cases. Here we report a case of successful fiberoptic bronchoscopy-assisted endotracheal intubation in a patient undergoing surgical resection of a large, high tracheal tumor causing severe tracheal stenosis. A 42-year-old Chinese man presented with dyspnea, intermittent irritable cough, and sleep deprivation for one and a half years. X-rays and computed tomography scan of the chest revealed an irregular pedunculated soft tissue mass within the tracheal lumen. The mass occupied over 90% of the lumen and caused severe tracheal stenosis. Endotracheal intubation was done to perform tracheal tumor resection under general anesthesia. After several failed conventional endotracheal intubation attempts, fiberoptic bronchoscopy-assisted intubation was successful. The patient received mechanical ventilation and then underwent tumor resection and a permanent tracheostomy. This case provides evidence of the usefulness of the fiberoptic bronchoscopy-assisted intubation technique in management of an anticipated difficult airway and suggests that tracheal intubation can be performed directly in patients with a tracheal tumor who can sleep in the supine position, even if they have occasional sleep deprivation and severe tracheal obstruction as revealed by imaging techniques.

    Dexmedetomidine has the favorable properties of sedation, sympatholysis, analgesia, and a low risk of apnea. These properties suggest that dexmedetomidine may be useful in procedural sedation. In view of this, we conducted a pilot trial to determine the feasibility of using dexmedetomidine as a sole agent for providing sedation during awake diagnostic flexible bronchoscopy. Patients presenting for awake diagnostic flexible bronchoscopy consented to participate in a trial of dexmedetomidine sedation for the procedure. In addition to local anesthetic topicalization of the airways, dexmedetomidine was infused at 0.5 μg/kg over 10 minutes followed by an infusion of 0.2 to 0.7 μg/kg/h titrating to a Ramsay Sedation Scale score of 3. Hemodynamic parameters (heart rate, blood pressure), oxygenation status (pulse oximetry), adverse events, use of rescue sedation, and patient and proceduralist satisfaction were recorded during the trial. Five of 9 recruited patients required rescue sedation to allow the procedure to proceed. Dexmedetomidine as a sole agent at an infusion of 0.5 μg/kg over 10 minutes followed by an infusion of 0.2 to 0.7 μg/kg/h is unable to provide adequate sedation for awake diagnostic flexible bronchoscopy without the need for rescue sedation in a large proportion of patients.

    Full Text Available Background and Aim: Due to its easy maneuverability, patient comfort and documented safety as an outpatient procedure, flexible bronchoscopy (FB has replaced rigid bronchoscopy for routine diagnostic use. Herein, we report our 34-year experience with outpatient performance of FB. Materials and Methods: This was a retrospective analysis of all FB procedures performed between September 1979 and November 2013 (period I: 1979-1990; period II: 1991-2000; period III: 2001-2013 in a tertiary care hospital. Demographic profile of patients, indications for performing FB, and annual and seasonal trends were noted from the records. Results: A total of 24,814 bronchoscopies were performed during the study period. The mean (SD age of patients (71.6% males was 48.4 (15.5 years. The number of procedures performed per decade showed an absolute increase by 322%. The most common indication for FB was suspected bronchogenic carcinoma (32.2% followed by pulmonary infections (18.6% and interstitial lung diseases (13%. The proportion of annual cases due to interstitial lung diseases (3.9% in period I to 16.2% in period III increased over the years, whereas disorders such as hemoptysis and pleural effusion showed a declining trend as an indication for FB. A seasonal trend was observed for diseases such as sarcoidosis, bronchogenic carcinoma and pulmonary infections. Six deaths were encountered during the study period in patients undergoing FB. Conclusion: FB is increasingly being performed in the diagnosis of respiratory disorders and is a safe outpatient procedure. Although bronchogenic carcinoma remains a common indication for performing FB, benign conditions such as pulmonary infections and sarcoidosis constitute important indications in the Indian scenario.

    2003-02-01

    Tracheobronchopathia osteochondroplastica (TO) is a rare benign disorder affecting the trachea and occasionally the bronchi. We report a case of TO presenting as a respiratory insufficiency. Chest radiograh revealed an irregular narrowing of the intra thoracic trachea and a parenchymal consolidation of the left lower lobe. Magnetic resonance examination of the chest showed a diffuse irregular thickening of the trachea and central bronchi, which had an intermediate signal intensity with punctiform low signal intensity suggesting calcifications and no contrast enhancement. The diagnosis was confirmed by bronchoscopy and biopsies.

    Full Text Available Topical airway anesthesia is known to improve tolerance and patient satisfaction during flexible bronchoscopy (FB. Lidocaine is commonly used, delivered as an atomized spray. The current study assesses safety and patient satisfaction for nasal anesthesia of a new atomization device during outpatient bronchoscopy in lung transplant recipients.Using a prospective, non-blinded, cross-over design, patients enrolled between 01-10-2014 and 24-11-2014 received 2% lidocaine using the standard reusable nasal atomizer (CRNA. Those enrolled between 25-11-2014 and 30-01-2015, received a disposable intranasal mucosal atomization device (DIMAD. After each procedure, the treating physician, their assistant and the patient independently rated side-effects and satisfaction, basing their responses on visual analogue scales (VAS. At their next scheduled bronchoscopy during the study period, patients then received the alternative atomizer. Written consent was obtained prior to the first bronchoscopy, and the study approved by the institutional ethics committee.Of the 252 patients enrolled between 01-10-2014 and 30-01-2015, 80 (32% received both atomizers. Physicians reported better efficacy (p = 0.001 and fewer side effects (p< = 0.001 for DIMAD in patients exposed to both procedures. Among patients with one visit, physicians and their assistants reported improved efficacy (p = 0.018, p = 0.002 and fewer side effects (p< = 0.001, p = 0.029 for the disposable atomizer, whereas patients reported no difference in efficacy or side effects (p = 0.72 and p = 0.20. No severe adverse events were noted. The cost of the reusable device was 4.08€ per procedure, compared to 3.70€ for the disposable device.Topical nasal anesthesia via a disposable intranasal mucosal atomization device (DIMAD offers comparable safety and patient comfort, compared to conventional reusable nasal atomizers (CRNA in lung transplant recipients. Procedural costs were reduced by 0.34€ per

    State-of-the-art image-guided intervention (IGI) systems for lung-cancer management draw upon high-resolution three-dimensional multi-detector computed-tomography (MDCT) images and bronchoscopic video. An MDCT scan provides a high-resolution three-dimensional (3D) image of the chest that is used for preoperative procedure planning, while bronchoscopy gives live intraoperative video of the endobronchial airway tree structure. However, because neither source provides live extraluminal information on suspect nodules or lymph nodes, endobronchial ultrasound (EBUS) is often introduced during a procedure. Unfortunately, existing IGI systems provide no direct synergistic linkage between the MDCT/video data and EBUS data. Hence, EBUS proves difficult to use and can lead to inaccurate interpretations. To address this drawback, we present a prototype of a multimodal IGI system that brings together the various image sources. The system enables 3D reconstruction and visualization of structures depicted in the 2D EBUS video stream. It also provides a set of graphical tools that link the EBUS data directly to the 3D MDCT and bronchoscopic video. Results using phantom and human data indicate that the new system could potentially enable smooth natural incorporation of EBUS into the system-level work flow of bronchoscopy.

    Full Text Available Background and objective The aim of this study is to determine the best reference values of the optimal evaluation indexes that identify different disease types. Disease identification was conducted using the YUV quantitative analysis of autofluorescence bronchoscopy (AFB images in the target areas. Furthermore, this study discusses the significance of AFB in the diagnosis of the central-type lung cancer. Methods A biopsy was conducted for cases that showed pathologic changes under either autofluorescence or white-light bronchoscopy. Moreover, MATLAB was used to carry out the quantitative analyses of lesion in multi-color spaces from AFB images. The cases were divided into different groups according to the pathological diagnosis of normal bronchial mucosa, inflammation, low-grade dysplasia (LGD, high-grade dysplasia (HGD, and invasive cancer. SPSS 11.5 was used to process the data for statistical analysis. Results The Y values were different and statistically different between invasive cancer and LGD (P<0.001 and invasive cancer and inflammation (P=0.040, respectively. The U values between invasive cancer and the other groups were statistically different (P<0.050. Similarly, the V values between invasive cancer and LGD and inflammation and normal bronchial mucosa were different. Lastly, the V values between normal bronchial mucosa and HGD and inflammation and normal bronchial mucosa were different. Conclusion The YUV values in the AFB effectively identified benign and malignant diseases and were proven to be effective scientific bases for the accurate AFB diagnosis of lung cancer.

    Full Text Available Background. The early diagnosis of malignant and premalignant changes of the bronchial mucosa remains a major challenge during bronchoscopy. Intravital staining techniques are not new. Previous small case series suggested that analysis of the bronchial mucosal surface using chromoendoscopy allows a prediction between neoplastic and nonneoplastic lesions. Objectives. The aim of the present study was to evaluate chromobronchoscopy as a method to identify malignant and premalignant lesions in the central airways in a prospective manner. Methods. In 26 patients we performed chromoendoscopy with 0.1% methylene blue during ongoing flexible white light bronchoscopy. Circumscribed lesions in central airways were further analyzed by biopsies and histopathologic examination. Results. In the majority of cases neither flat nor polypoid lesions in the central airways were stained by methylene blue. In particular, exophytic growth of lung cancer did not show any specific pattern in chromobronchoscopy. However, a specific dye staining was detected in one case where exophytic growth of metastatic colorectal cancer was present in the right upper lobe. In two other cases, a circumscribed staining was noted in unsuspicious mucosa. But histology revealed inflammation only. Conclusions. In contrast to previous studies, the present findings clearly indicate that chromobronchoscopy is not useful for early detection of malignant or premalignant lesions of the central airways.

    Midazolam is widely used as a sedative agent to produce amnesia in patients undergoing fibre-optic bronchoscopy. However, if a patient does not receive sufficient local anaesthesia, continuous severe cough and physical movement may interrupt the procedure and reduce its safety. We therefore examined whether codeine phosphate is a useful premedication for bronchoscopy. The study design was a randomized comparison between codeine phosphate and a placebo in patients undergoing light local anaesthesia and midazolam sedation. We used low dose local anaesthesia (5 ml of nebulized 2% xylocaine) on the assumption of insufficient local anaesthesia. Patients were allocated to receive codeine phosphate 0.4 mg kg-1 or a saline placebo 60 min before they were sedated with i.v. midazolam. If the patients exhibited severe cough during bronchoscopy, intrabronchial supplemental local anaesthesia (2% xylocaine solution in 1 ml increments) was instilled via a bronchoscope to the trachea and segmental bronchi to suppress the cough. The dose of supplemental xylocaine was assessed and the requirements were significantly lower in the codeine group compared to the placebo group: 36.4 +/- 10.2 mg vs. 95.1 +/- 24.6 mg, respectively. After bronchoscopy, patients were interviewed by a doctor to assess their willingness to undergo a repeat procedure if one was clinically indicated, but no significant difference was observed between the two groups. If local anaesthesia is insufficient, midazolam together with codeine phosphate premedication is useful for both the patient and the bronchoscopist.

    The aim of this study was to compare helical CT with fiberoptic bronchoscopy findings to appraise the medium-term results of proximal-airways stenting. Twenty-five patients with 28 endobronchial metallic stents inserted for local advanced malignancy (n=13) or benign diseases (n=12) underwent follow-up CT from 3 days to 50 months (mean 8 months). All studies were obtained using helical CT with subsequent multiplanar reformation and three-dimensional reconstruction including virtual bronchoscopy. The location, shape, and patency of stents and adjacent airway were assessed. The results of CT were compared with the results of fiberoptic bronchoscopy obtained with a mean delay of 2.5 days (SD 9 days) after CT scan. Twelve stents (43%) remained in their original position, patent and without deformity. Sixteen stents were associated with local complications: migration (n=6); external compression with persistent stenosis (n=4); local recurrence of malignancy (n=4); fracture (n=1); and non-congruence between the airway and the stent (n=1). The CT demonstrated all the significant abnormalities demonstrated at fiberoptic bronchoscopy except two moderate stenoses (20%) related to granulomata at the origin of the stent. Ten of 14 stents inserted for benign conditions were without complications as compared with 2 of 14 in malignant conditions (p=0.008). Computed tomography is an accurate noninvasive method for evaluating endobronchial stents. The CT is a useful technique for follow-up of patients who have undergone endobronchial stenting. (orig.)

    Full Text Available Aim: The aim of the study was to compare transcricoid injection with "spray as you go" technique for diagnostic fibreoptic bronchoscopy, to perform the procedure without sedation and to record any complication or side effects. Methods: Sixty patients belonging to the age group 20-70 years, undergoing diagnostic bronchoscopy over a period of 6 months, were randomly selected and divided into two groups alternatively to receive 3 ml of 4% lignocaine by a single transcricoid puncture (group I or 2 ml of 4% lignocaine instilled through the bronchoscope on to the vocal cords and further 1 ml of 2% lignocaine into each main bronchus (group II. Additional dose of lignocaine as required was given in both the groups. All patients were given intramuscular atropine 0.6 mg, 20 min before the procedure. Nebulisation with 3 ml of 4% lignocaine was given to all patients. The time from nasal insertion of the bronchoscope to reach the carina was recorded, and the total dose of lignocaine required in both the groups was calculated and compared. The cough episodes during the procedure, systolic blood pressure, and pulse rate were compared before the procedure and 5 min after the procedure in both the groups. A 0-10 visual analogue scale (VAS was used to assess discomfort 30 min after the procedure. Results: The time to reach carina was more in group II (P<0.02, and cough episodes were also more in group II (P<0.05 than in group I. The vitals before the procedure were comparable in both the groups, but 5 min after the procedure the vitals were more stable in group I than in group II, and the total dose of lignocaine required in group II was more than in group I (P<0.001. However, the VAS score was comparable in both the groups. Conclusion: Transcricoid puncture for diagnostic bronchoscopies without sedation was associated with no complication and discomfort and required lesser dose of local anaesthetic with more stable vitals and good conditions for bronchoscopists.

    Experimenatal results on the development of a Laser-Induced Fluorescence Bronchoscopy(LIFB) for the detection and localization of early lung cancer are reported in this paper. The system utilizes fluorescence of photosensitizer drug to provide real time video imaging for the examined lung tissue. Color filters are used to differentiate signal from background and a computer image processing technique is also applied to subtract the background. Moreover, a pseudocolor contrast enhancement method was developed to enhance the fluorescence image displayed on the vidio monitor. Suspicious areas are identified by pseudocolor image to guide biopsy, and several clinical trials show that sensitivity and contrast capability of the system should permit the detection and localization of early lung cancer.

    Full Text Available Lung cancer has become a complicated health problem in the world. In 2005, approximately 172,500 people diagnosed with lung cancer in the United States. In Indonesia, lung cancer ranks fourth highest. Lung cancer is also the most common cause of death from cancer, so we need appropriate early detection modality to reduce the number of deaths from lung cancer. Compared with other modalities that currently available, Autofluorescence Bronchoscopy (AFB seems to have better accuracy in early diagnosis of lung cancer. AFB can be used to evaluate patients with high-grade sputum atypia, evaluating patients with suspected or had suffered from lung cancer, and have a role in follow-up of bronchial high-grade intraepithelial neoplasia.

    Expression of three major resistance genes MDR1, MRP1 and LRP was investigated in small cell lung cancer, non-small cell lung cancer and metastasis. Single biopsies of bronchoscopy from 73 patients were performed to investigate expression of these three resistance genes by reverse transcriptase-polymerase chain reaction. Relations between gene expression and patient age, smoking status, histology, and chemotherapy were evaluated. A more frequent expression of MDR1 (77 versus 66%), MRP1 (91 versus 72%) and LRP (77 versus 63%) genes was detected in the malignant biopsies than in the non-malignant, respectively. In the metastasis biopsies, expression of these genes was markedly increased. No significant difference was observed between specimens before and after chemotherapy. Biopsies from progressing cancer showed higher MDR1, MRP1 and LRP gene expression. In conclusion, these data reveal a major role of MRP1 in intrinsic resistance and the high gene expression of MDR1 and MRP1 in relapsed diseases.

    Full Text Available BACKGROUND: Acute lung injury (ALI is a major factor determining morbidity following burns and inhalational injury. In experimental models, factors potentially contributing to ALI risk include inhalation of toxins directly causing cell damage; inflammation; and infection. However, few studies have been done in humans. METHODS: We carried out a prospective observational study of patients admitted to the NC Jaycees Burn Center who were intubated and on mechanical ventilation for burns and suspected inhalational injury. Subjects were enrolled over an 8-month period and followed till discharge or death. Serial bronchial washings from clinically-indicated bronchoscopies were collected and analyzed for markers of cell injury and inflammation. These markers were compared with clinical markers of ALI. RESULTS: Forty-three consecutive patients were studied, with a spectrum of burn and inhalation injury severity. Visible soot at initial bronchoscopy and gram negative bacteria in the lower respiratory tract were associated with ALI in univariate analyses. Subsequent multivariate analysis also controlled for % body surface area burns, infection, and inhalation severity. Elevated IL-10 and reduced IL-12p70 in bronchial washings were statistically significantly associated with ALI. CONCLUSIONS: Independently of several factors including initial inhalational injury severity, infection, and extent of surface burns, high early levels of IL-10 and low levels of IL-12p70 in the central airways are associated with ALI in patients intubated after acute burn/inhalation injury. Lower airway secretions can be collected serially in critically ill burn/inhalation injury patients and may yield important clues to specific pathophysiologic pathways.

    Objective To evaluate the efficacy and safety of percutaneous tracheostomy by means of single-step dilation with fiber optic bronchoscopy assistance in critical care patients under mechanical ventilation. Methods Between the years 2004 and 2014, 512 patients with indication of tracheostomy according to clinical criteria, were prospectively and consecutively included in our study. One-third of them were high-risk patients. Demographic variables, APACHE II score, and days on mechanical ventilation prior to percutaneous tracheostomy were recorded. The efficacy of the procedure was evaluated according to an execution success rate and based on the necessity of switching to an open surgical technique. Safety was evaluated according to post-operative and operative complication rates. Results The mean age of the group was 64 ± 18 years (203 women and 309 males). The mean APACHE II score was 21 ± 3. Patients remained an average of 11 ± 3 days on mechanical ventilation before percutaneous tracheostomy was performed. All procedures were successfully completed without the need to switch to an open surgical technique. Eighteen patients (3.5%) presented procedure complications. Five patients experienced transient desaturation, 4 presented low blood pressure related to sedation, and 9 presented minor bleeding, but none required a transfusion. No serious complications or deaths associated with the procedure were recorded. Eleven patients (2.1%) presented post-operative complications. Seven presented minor and transitory bleeding of the percutaneous tracheostomy stoma, 2 suffered displacement of the tracheostomy cannula, and 2 developed a superficial infection of the stoma. Conclusion Percutaneous tracheostomy using the single-step dilation technique with fiber optic bronchoscopy assistance seems to be effective and safe in critically ill patients under mechanical ventilation when performed by experienced intensive care specialists using a standardized procedure.

    Rationale: Advanced bronchoscopy techniques such as electromagnetic navigation (EMN) have been studied in clinical trials, but there are no randomized studies comparing EMN with standard bronchoscopy. Objectives: To measure and identify the determinants of diagnostic yield for bronchoscopy in patients with peripheral lung lesions. Secondary outcomes included diagnostic yield of different sampling techniques, complications, and practice pattern variations. Methods: We used the AQuIRE (ACCP Quality Improvement Registry, Evaluation, and Education) registry to conduct a multicenter study of consecutive patients who underwent transbronchial biopsy (TBBx) for evaluation of peripheral lesions. Measurements and Main Results: Fifteen centers with 22 physicians enrolled 581 patients. Of the 581 patients, 312 (53.7%) had a diagnostic bronchoscopy. Unadjusted for other factors, the diagnostic yield was 63.7% when no radial endobronchial ultrasound (r-EBUS) and no EMN were used, 57.0% with r-EBUS alone, 38.5% with EMN alone, and 47.1% with EMN combined with r-EBUS. In multivariate analysis, peripheral transbronchial needle aspiration (TBNA), larger lesion size, nonupper lobe location, and tobacco use were associated with increased diagnostic yield, whereas EMN was associated with lower diagnostic yield. Peripheral TBNA was used in 16.4% of cases. TBNA was diagnostic, whereas TBBx was nondiagnostic in 9.5% of cases in which both were performed. Complications occurred in 13 (2.2%) patients, and pneumothorax occurred in 10 (1.7%) patients. There were significant differences between centers and physicians in terms of case selection, sampling methods, and anesthesia. Medical center diagnostic yields ranged from 33 to 73% (P = 0.16). Conclusions: Peripheral TBNA improved diagnostic yield for peripheral lesions but was underused. The diagnostic yields of EMN and r-EBUS were lower than expected, even after adjustment.

    Patients may find bronchoscopy without sedation unpleasant. There is some evidence that patient satisfaction correlates with amnesia for the procedure. For several years we have used doses of midazolam sufficient to put patients lightly asleep hoping to produce complete amnesia. We looked at practical aspects of this technique over a 2-year period. We studied 337 consecutive patients. They were 219 men and 118 women of mean age 63 +/- 12.4 (SD). Sixty-seven patients were aged 75 years or over and the eldest was 86. Sixty-three patients were already hospital inpatients but the remainder were seen as day cases. Midazolam was given by slow i.v. injection over several minutes until the patient was judged to be lightly asleep. Patients were given supplemental oxygen (3 l min-1) and monitored by ECG and pulse oximetry. A note was made of the time at which they awakened, defined as when nursing staff felt the patients were awake enough to have a cup of tea and toast. Patients were asked if they had any memory of the procedure both on awakening and when seen a few days later to discuss the results. The procedures were carried out in a well-staffed Day Case Unit with a recovery area. The mean dose of midazolam used was 10.8 mg (mean +/- SD = 0.16 +/- 0.095 mg kg-1). The midazolam was given over a median of 4 min (range 1-15 min). Patients took 59 +/- 45 min (mean +/- SD) to wake up. Twenty-eight patients were given flumazanil to reverse the sedation (11 for concern over bleeding following biopsies, three for desaturation during and three after procedure, four as they were frail, two as they were restless, two as they were hypotensive after procedure and three for miscellaneous reasons). Only nine patients could remember any part of the procedure. Incremental doses of midazolam given slowly until patients are lightly asleep almost invariably produce complete amnesia for bronchoscopy. This is a safe technique but patients need careful monitoring and may require reversal of

    The usual hemodynamic response to laryngoscopy and bronchoscopy is an increase in heart rate and arterial blood pressure. Previous work has reported that 10%-18% of the patients develop ischemic ST segment changes during the procedure. Therefore, we performed a prospective, randomized, double-blinded study in 36 patients scheduled for elective microlaryngeal and bronchoscopic surgical procedures to evaluate the effects of 300-microg oral clonidine premedication (n = 18) or placebo (n = 18) on the hemodynamic alterations and the incidence of perioperative myocardial ischemic episodes. Myocardial ischemia was assessed by using continuous electrocardiographic monitoring, beginning 30 min before, and lasting until 24 h after the operation. During the procedure, patients receiving placebo exhibited a significant increase (mean +/- SD) in arterial blood pressure (the systolic increasing from 137+/-11 to 166+/-17 mm Hg, the diastolic increasing from 80+/-11 to 97+/-14 mm Hg) and heart rate (increasing from 79+/-15 to 97+/-12 bpm) compared with the baseline and with the clonidine group. A dose of 300-microg clonidine blunted the hemodynamic response to endoscopy. Ventricular arrhythmias were more frequent in patients who were not premedicated with clonidine. Two patients in the control group, but none in the clonidine group, had evidence of myocardial ischemia. These data should encourage routine premedication with clonidine in patients undergoing microlaryngoscopic and bronchoscopic procedures.

  5. Anatomy and bronchoscopy of the porcine lung. A model for translational respiratory medicine.

    The porcine model has contributed significantly to biomedical research over many decades. The similar size and anatomy of pig and human organs make this model particularly beneficial for translational research in areas such as medical device development, therapeutics and xenotransplantation. In recent years, a major limitation with the porcine model was overcome with the successful generation of gene-targeted pigs and the publication of the pig genome. As a result, the role of this model is likely to become even more important. For the respiratory medicine field, the similarities between pig and human lungs give the porcine model particular potential for advancing translational medicine. An increasing number of lung conditions are being studied and modeled in the pig. Genetically modified porcine models of cystic fibrosis have been generated that, unlike mouse models, develop lung disease similar to human cystic fibrosis. However, the scientific literature relating specifically to porcine lung anatomy and airway histology is limited and is largely restricted to veterinary literature and textbooks. Furthermore, methods for in vivo lung procedures in the pig are rarely described. The aims of this review are to collate the disparate literature on porcine lung anatomy, histology, and microbiology; to provide a comparison with the human lung; and to describe appropriate bronchoscopy procedures for the pig lungs to aid clinical researchers working in the area of translational respiratory medicine using the porcine model.

    Full Text Available Background: The importance of rapid and accurate cytopathological diagnosis in bronchial cancers is increasing due to advances in treatment modalities.Aims: We evaluated the diagnostic methods and cytologic subtypes of bronchial cancers to determine the diagnostic reliability of different bronchoscopic techniques.Material and methods: Retrospective data were obtained from the hospital files and pathological specimens of the patients with diagnosis of primary lung cancer from a period of 36 months. Cytological tumor typing was determined using histopathology of bronchoscopic forceps biopsy (FB, bronchial-bronchoalveolar lavage (BL, bronchial brushing (BB, transbronchial fine-needle biopsy. Computed tomography or ultrasonography guided transthoracic biopsy and surgical biopsies were used where the other interventional methods were inadequate for diagnosis.Results: A total of 124 patients were diagnosed during study period. 119 (96% of them were male. The median age was 68, ranging between 36 and 88 years. Histopathologic subtypes were determined as non-small cell carcinoma (NSCC in 104 (83.9%, squamous cell carcinoma in 64 (51.6%, adenocarcinoma in 16 (12.9%, NSCC not otherwise specified in 24 (19.3% and small cell carcinoma in 20 (16.1% patients. The combination of FB, BL and BB established the diagnosis of bronchogenic carcinoma in most of the cases (92.6%.Conclusions: Lung cancer is seen commonly in elderly male patients with smoking history and squamous cell carcinoma is the most common cytologic type. High diagnostic accuracy can be achieved by a combination of bronchoscopic FB, BB and BL procedures. Keywords: Bronchoscopy; Lung cancer; Bronchial brushing

    In X-ray guided bronchoscopy of peripheral pulmonary lesions, airways and nodules are hardly visible in X-ray images. Transbronchial biopsy of peripheral lesions is often carried out blindly, resulting in degraded diagnostic yield. One solution of this problem is to superimpose the lesions and airways segmented from preoperative 3D CT images onto 2D X-ray images. A feature-based 2D/3D registration method is proposed for the image fusion between the datasets of the two imaging modalities. Two stereo X-ray images are used in the algorithm to improve the accuracy and robustness of the registration. The algorithm extracts the edge features of the bony structures from both CT and X-ray images. The edge points from the X-ray images are categorized into eight groups based on the orientation information of their image gradients. An orientation dependent Euclidean distance map is generated for each group of X-ray feature points. The distance map is then applied to the edge points of the projected CT images whose gradient orientations are compatible with the distance map. The CT and X-ray images are registered by matching the boundaries of the projected CT segmentations to the closest edges of the X-ray images after the orientation constraint is satisfied. Phantom and clinical studies were carried out to validate the algorithm's performance, showing a registration accuracy of 4.19(± 0.5) mm with 48.39(± 9.6) seconds registration time. The algorithm was also evaluated on clinical data, showing promising registration accuracy and robustness.

    Objective: The aim of this study was to evaluate the clinical value of virtual bronchoscopy (VB) in aiding diagnosis of peripheral lung cancer by transbronchial biopsy (TBB). In addition, we sought to systematically analyze the factors that affect the diagnostic sensitivity of VB-guided TBB for the evaluation of peripheral lung cancers. Materials and methods: A hundred and twenty-two peripheral lung cancers from 122 patients (82 men and 40 women, 38-84 years; median 68.5 years) who were performed VB-guided TBB were evaluated retrospectively. VB was reconstructed from 1- or 0.5-mm slice thickness images of multi-detector CT (MDCT). Experienced pulmonologists inserted the conventional and ultrathin bronchoscopes into the target bronchus under direct vision following the VB image. Results: A definitive diagnosis was established by VB-guided TBB in 96 lesions (79%). The diagnostic sensitivity of small pulmonary lesions {<=}30 mm in maximal diameter (71%) was significantly lower than that of lesions >30 mm (91%, p = 0.008). For small pulmonary lesions {<=}30 mm (n = 76), internal opacity of the lesion was the independent predictor of diagnostic sensitivity by VB-guided TBB, and the non-solid type lung cancers were significantly lower than the solid type and part-solid type lung cancers for diagnostic sensitivity (odds ratio = 0.161; 95% confidence interval = 0.033-0.780; p = 0.023). Conclusion: Use of an ultrathin bronchoscope and simulation with VB reconstructed by high quality MDCT images is thought to improve pathological diagnosis of peripheral lung cancers, especially for solid and partly solid types. For small pulmonary lesions {<=}30 mm, the lesion internal opacity is a significant factor for predicting the diagnostic sensitivity, and the sensitivity was low for small non-solid type of lung cancers.

    Full Text Available Aims: To evaluate the diagnostic utility of virtual bronchoscopy, multiplanar reformatted images, and minimal-intensity projection in assessing airway stenoses. Settings and Design: It was a prospective study involving 150 patients with symptoms of major airway disease. Materials and Methods: Fifty-six patients were selected for analysis based on the detection of major airway lesions on fiber-optic bronchoscopy (FB or routine axial images. Comparisons were made between axial images, virtual bronchoscopy (VB, minimal-intensity projection (minIP, and multiplanar reformatted (MPR images using FB as the gold standard. Lesions were evaluated in terms of degree of airway narrowing, distance from carina, length of the narrowed segment and visualization of airway distal to the lesion. Results: MPR images had the highest degree of agreement with FB (Κ = 0.76 in the depiction of degree of narrowing. minIP had the least degree of agreement with FB (Κ = 0.51 in this regard. The distal visualization was best on MPR images (84.2%, followed by axial images (80.7%, whereas FB could visualize the lesions only in 45.4% of the cases. VB had the best agreement with FB in assessing the segment length (Κ = 0.62. Overall there were no statistically significant differences in the measurement of the distance from the carina in the axial, minIP, and MPR images. MPR images had the highest overall degree of confidence, namely, 70.17% (n = 40. Conclusion: Three-dimensional reconstruction techniques were found to improve lesion evaluation compared with axial images alone. The technique of MPR images was the most useful for lesion evaluation and provided additional information useful for surgical and airway interventions in tracheobronchial stenosis. minIP was useful in the overall depiction of airway anatomy.

    Full Text Available Background: The use of music to relieve anxiety has been examined in various studies, but the results are inconclusive. Methods: From April to October 2015, 160 patients undergoing examination of pulmonary nodules were randomly assigned to MusiCure or no music. MusiCure was administered through earplugs to ensure blinding of the staff and was played from admission to the operating theatre to the end of the bronchoscopy. Spielberger's State-Trait Anxiety Inventory (STAI was administered on admission, immediately before bronchoscopy, and on discharge. Secondary outcomes were p-cortisol, physiological variables, dosage of sedatives, movements measured by Actigraph, bronchoscopy duration, number of re-examinations, and overall perception of the sounds in the operating theatre measured by Visual analogue scale. Results: The STAI scores were similar on admission, but after a 10-min wait in the operating theatre, scores varied significantly between patients with and without music, with lower scores in the music group [median (interquartile range, IQR 35 (18 vs. 43 (25; p=0.03]. Post hoc multiple regression revealed treatment group as insignificant when adjusting for sex and baseline anxiety. However, there was a significantly more positive perception of the sounds in the operating theatre in the music group (median (IQR 8.2 (1.8 vs. 5.4 (6.8; p<0.0001 and fewer re-examinations in the music group (19.2% vs. 7.7%, p<0.032. Conclusions: Ten minutes with MusiCure does not alter anxiety when adjusting for baseline anxiety and sex. The current study indicates that this field of research has many confounders.

    2013-12-01

    Relapsing polychondritis (RP) is an uncommon disease that is characterized by inflammation and destruction of cartilaginous structures. When tracheobronchial tree is involved, respiratory obstructive symptoms can occur. A 35-year-old man, with a previous diagnosis of RP, was scheduled for rigid bronchoscopy to relieve dyspnea, caused by subglottic stenosis. After laser splitting of the subglottic web, the spontaneous respiration of the patient was insufficient, and hypercarbia developed progressively even with assisted ventilation. After 20 minutes of aggressive hyperventilation to reduce end-tidal CO2 level, sudden extreme tachycardia and hypotension developed. Ventilation rate was reduced and prolonged expiration time was allowed to alleviate a near-tampon status from dynamic hyperinflation. After the hemodynamic status was stabilized, the patient was transferred to the ICU for mechanical ventilation. He received ICU care for 30 days, and now, he was on supportive care on a ward, considering Y stent insertion to prevent luminal collapse from tracheobronchomalacia.

    Aim: Latent tuberculosis infections (LTBI) contain a significant reservoir for future epidemics. Screening of health care workers (HCWs) in a high-risk tuberculosis (TB) environment is an important strategy in TB control. The study aimed to assess the prevalence of LTBI among high risk Egyptian HCWs and to assess infection associated risk factors. Methods: Fifty-two HCWs who work at intensive care unit (ICU), bronchoscopy unit, and chest diseases department were tested for LTBI using both tuberculin skin test (TST) and Quantiferon TB Gold in-tube test (QFT). Risk factors for infection, knowledge of HCWs towards different aspects of TB infection and agreement between TST and QFT were also evaluated. Results: Prevalence of LTBI in this study was 13.5% by QFT and TST. It was 13.6% by TST alone and 10.3% by QFT alone. There was good concordance between both tests (Kappa=0.713). There was a statistically significant association between prevalence of LTBI and age of staff ≥30 yr (p=0.002), period of working experience (p=0.006) and working at the Bronchoscopy Unit (p=0.001). The total knowledge of HCWs towards different aspects of TB infection was generally good. Conclusion: Although the participants in the current study were among high risk HCWs, the prevalence of LTBI was low. Bacille Calmette-Guerin (BCG) vaccination, young age, short employment duration, good knowledge and a good infection control were the predictors of low risk of contracting TB at our hospitals. The risk of TB infection in resource-limited countries can be reduced with simple continuous educational and administrative infection control programmes. PMID:27777875

    Foreign body aspiration is common in children, especially those under 3 years of age. Chest radiography and CT are the main imaging modalities for the evaluation of these children. Management of children with suspected foreign body aspiration (SFBA) mainly depends on radiological findings. To investigate the potential use of low-dose multidetector CT (MDCT) and virtual bronchoscopy (VB) in the evaluation and management of SFBA in children. Included in the study were 37 children (17 girls, 20 boys; age 4 months to 10 years, mean 32 months) with SFBA. Chest radiographs were obtained prior to MDCT in all patients. MDCT was performed using a low-dose technique. VB images were obtained in the same session. Conventional bronchoscopy (CB) was performed within 24 h on patients in whom an obstructive abnormality had been found by MDCT and VB. Obstructive pathology was found in 16 (43.25%) of the 37 patients using MDCT and VB. In 13 of these patients, foreign bodies were detected and removed via CB. The foreign bodies were located in the right main bronchus (n = 5), in the bronchus intermedius (n = 6), in the medial segment of the middle lobe bronchus (n = 1), and in the left main bronchus (n = 1). In the remaining three patients, the diagnosis was false-positive for an obstructive pathology by MDCT and VB; the final diagnoses were secretions (n = 2) and schwannoma (n = 1), as demonstrated by CB. In 21 patients in whom no obstructive pathology was detected by MDCT and VB, CB was not performed. These patients were followed for 5-20 months without any recurrent obstructive symptomatology. Low-dose MDCT and VB are non-invasive radiological modalities that can be used easily in the investigation of SFBA in children. MDCT and VB provide the exact location of the obstructive pathology prior to CB. If obstructive pathology is depicted with MDCT and VB, CB should be performed either for confirmation of the diagnosis or for the diagnosis of an alternative cause for the obstruction

    Full Text Available Objective: Fiberoptic bronchoscopy (FOB is the most frequently used tool for invasive pulmonary evaluation with high diagnostic yield and low incidence of major complications. These advantages led to increasing use of FOB in intensive care units. In this article, we discussed our experiences of FOB applications in mechanical ventilated critically ill patients. Materials and Methods: We investigated FOB procedures of 118 patients on mechanical ventilation for respiratory failure in intensive care unit retrospectively. All patients’ demographic data, indications, complications and arterial blood gas analyses belong to before and after bronchoscopy were evaluated. Results: FOB indications of the patients were 55.1% for mucoid plug clearance, 9.3% for treatment of atelectasia, 7.6% for identifying hemorrhagic foci, 17.8% for tracheostomy management, 6.8% for bronchoalveolar lavage and 3.4% for exploratory purposes. Overall complication rate of FOB was 11.9%. Arterial blood gas analyses statistically improved after FOB. Conclusion: In this study, we observed that FOB is being performed with many different indications and acceptable complication rates in our intensive care unit and also contributes to diagnose and treatment of intensive care patients.

    Purpose: To compare spiral computed tomography (CT) and electron-beam CT (EBT) for 3D and virtual CT-bronchoscopy. Materials and methods: 17 patients with various disorders of the tracheobronchial system were examined using fiberoptic bronchoscopy, spiral CT and EBT. 3D images were reconstructed from CT data sets using automated segmentation based on volume-growing methods. Surface-rendered, volume-rendered, and hybrid reconstructions were visualized in real time using a data helmet. Results: All data sets could be processed to high-quality three-dimensional (3D) and virtual reconstructions. The reduction of motion artifacts due to shorter scan times made EBT data sets better suited for automated segmentation and less susceptible to motion artifacts. 3D and virtual reconstructions did not increase the diagnostic sensitivity of CT compared to axial reconstructions alone. Conclusions: Shorter scan times of CT imaging yield higher-quality 3D and virtual reconstructions. Modern reconstruction techniques are valuable visualization tools for select indications and are the prerequisite for future developments in computer-aided medicine. (orig.)

    que representam diagnósticos diferenciais.BACKGROUND: Pulmonary tuberculosis is an infectious disease of high prevalence and incidence. The use of sputum bacilloscopy is a sure and speedy way of reaching a diagnosis. However as 30% to 50% of the bearers of pulmonary tuberculosis have a negative sputum smear or have no sputum the fiber bronchoscopy acquires a special importance. OBJECTIVES: To evaluate the sensitivity of the specimens collected by means of the fiber bronchoscopy (brochoalveolar lavage and transbronchial biopsy for the diagnosis of patients suspected of having pulmonary tuberculosis, without confirmation by sputum bacilloscopy. METHOD: By review of the ledgers of fiber bronchoscopies carried out from March 1997 to March 2001, we identified and included in the study patients over 18 years of age and referred with suspicion of tuberculosis and at least three negative sputum smears. Data regarding age, gender, changes detected at thorax imaging and endoscopy were collected. RESULTS: Fifty-two patients with ages ranging from 19 to 77 years (median of 39, were included, 58% were of the male gender and 37% were patients from the Official Health System. Prevailing finding at chest X-ray was the alveolar infiltrate (80%. In 35 patients tuberculosis was the final diagnosis (one with associated neoplasia; in 28 patients (80% diagnosis was achieved by bronchoscopy. Other diagnoses disclosed by bronchoscopy were neoplasias, histoplasmosis chronic eosinophil alvelolitis, pneumonia by Pneumocystis carinii and pulmonary fibrosis. CONCLUSION: results of this study point to the use of fiber bronchoscopy in patients suspect of tuberculosis, not diagnosed thorough sputum bacilloscopy, not only for pulmonary tuberculosis but also of those that represent differential diagnoses.

    A 4-year-old boy presented for elective bronchoscopy after years of pharmacologically unresponsive reactive airway disease that limited physical activity. After mask induction with nitrous oxide and sevoflurane, the patient was noted to be intermittently in a hemodynamically stable tachyarrhythmia. The anesthesia machine, though equipped with electrocardiogram (ECG) recording capabilities, malfunctioned during the case and was not able to print a rhythm strip. As a substitute, a smartphone picture and video were recorded. In the recovery room, initial 12-lead ECG showed sinus tachycardia. Shortly after, a presumptive diagnosis of Wolff-Parkinson White was given upon review of the smartphone recordings by the pediatric cardiologist on service. Twelve lead ECG was repeated which showed intermittent Wolff-Parkinson White. This case highlights 2 points. First, any prolonged or sustained pediatric dysrhythmia revealed during anesthesia warrants further investigation and should not be assumed secondary to an anesthetic drug. Second, ubiquitous smartphones are an excellent tool for capturing data that the monitor is unable to capture.

    Cancer is the second leading cause of death in the western world. Early diagnosis and targeted therapy provide the basis for planning effective treatment. Diseases like cancer generally begin with alterations at the molecular level. When the number of affected cells reaches the threshold for anatomical change, the disease can already be so advanced that it is too late for successful treatment. Equally, morphological change is not necessarily associated with malignancy. Diagnosis and staging of cancer, and evaluation of therapeutic success, depend today to a large extent on imaging techniques like computed tomography (CT) and magnetic resonance tomography (MRT). However, these can only be used to identify anatomical changes in lesions. Increasingly, imaging techniques like positron emission tomography (PET) are used that are based at the molecular level. Functional imaging techniques detect functional changes in tissues that play a role in the diagnosis and staging of the disease. Virtual reality techniques, especially virtual endoscopy, have also become more important in PET-CT diagnostics. On the one hand, these methods enable simultaneous visualisation of morphological and metabolic relationships; on the other hand, the enormous amount of image data from PET-CT can be made understandable in an intuitive form with the aid of endoluminal three-dimensional (3-D) images and scenes. The prerequisite is that the image data from PET and CT are segmented after fusion using image analysis techniques and subsequently projected using a 3-D imaging system and virtual reality techniques. Together with the Department of Nuclear Medicine of the Technical University, Munich, a system has been developed for virtual bronchoscopy that is intended to improve diagnostic precision in cases of bronchial carcinoma.

ICG solutions in a 96-well plate and ex vivo porcine lungs were examined to optimize ICG concentrations and injection volumes. Transbronchial ICG injection (n=4 was assessed in comparison to a traditional transpleural approach (n=3, where after thoracotomy an ICG solution (100 μL at 100 μg/mL was injected into the porcine right upper lobe for SN identification. For further translation into clinical use, transbronchial ICG injection prior to thoracotomy followed by NIR thoracoscopic imaging was validated (n=3. ENB was used for accurate targeting in two pigs with a pseudo-tumor.The ICG fluorescence at 10 μg/mL was the brightest among various concentrations, unchanged by the distance between the thoracoscope and ICG solutions. Injected ICG of no more than 500μ L showed a localized fluorescence area. All 7 pigs showed a bright paratracheal lymph node within 15 minutes post-injection, with persistent fluorescence for 60 minutes. The antecedent transbronchial ICG injection succeeded in SN identification in all 3 cases at the first thoracoscopic inspection within 20 minutes post-injection. The ENB system allowed accurate ICG injection surrounding the pseudo-tumors.ENB-guided ICG injection followed by NIR thoracoscopy was technically feasible for SN mapping in the porcine lung. This promising platform may be translated into human clinical trials and is suited for MIS.

    Purpose: Post-treatment radiation injury to central and peripheral airways is a potentially important, yet under-investigated determinant of toxicity in lung stereotactic ablative radiotherapy (SAbR). We integrate virtual bronchoscopy technology into the radiotherapy planning process to spatially map and quantify the radiosensitivity of bronchial segments, and propose novel IMRT planning that limits airway dose through non-isotropic intermediate- and low-dose spillage. Methods: Pre- and ∼8.5 months post-SAbR diagnostic-quality CT scans were retrospectively collected from six NSCLC patients (50–60Gy in 3–5 fractions). From each scan, ∼5 branching levels of the bronchial tree were segmented using LungPoint, a virtual bronchoscopic navigation system. The pre-SAbR CT and the segmented bronchial tree were imported into the Eclipse treatment planning system and deformably registered to the planning CT. The five-fraction equivalent dose from the clinically-delivered plan was calculated for each segment using the Universal Survival Curve model. The pre- and post-SAbR CTs were used to evaluate radiation-induced segmental collapse. Two of six patients exhibited significant segmental collapse with associated atelectasis and fibrosis, and were re-planned using IMRT. Results: Multivariate stepwise logistic regression over six patients (81 segments) showed that D0.01cc (minimum point dose within the 0.01cc receiving highest dose) was a significant independent factor associated with collapse (odds-ratio=1.17, p=0.010). The D0.01cc threshold for collapse was 57Gy, above which, collapse rate was 45%. In the two patients exhibiting segmental collapse, 22 out of 32 segments showed D0.01cc >57Gy. IMRT re-planning reduced D0.01cc below 57Gy in 15 of the 22 segments (68%) while simultaneously achieving the original clinical plan objectives for PTV coverage and OAR-sparing. Conclusion: Our results indicate that the administration of lung SAbR can Result in significant injury to

    The role of flexible fiberoptic bronchoscopy (FFB) in the evaluation of pediatric lung disease has expanded dramatically since the original description of the procedure by Wood and Fink in 1978.FFB can be used to evaluate airway anatomy, obtain secretions for culture and biochemical analysis and obtain airway cells or parenchymal tissues for evaluation. Both the upper and lower airway can be examined during FFB. Visual examination can diagnose a variety of congenital abnormalities ( Table 1 ). During FFB a dynamic evaluation of the airways, including the movement of the glottis, vocal cords and lower airways during the respiratory cycle can be performed. These observations can diagnose airway collapse due to malacia or obstruction due to external compression. Additionally, the diameter of the airway lumen and character of the airway mucosa can easily be evaluated. FFB can also identify airway obstruction by secretions and mucus plugs, blood, foreign bodies or masses. Bronchoalveolar lavage (BAL) allows collection of airway and alveolar secretions for evaluation of cellular and immunologic components, evidence of infection and cytology. Therapeutic lavage can be used to treat atelectasis by removing secretions obstructing airways. This approach can be helpful in children with inspissated secretions obstructing both large and small airways ( Figure 1 ). Therapeutic lavage has also been used in the treatment of alveolar proteinosis. Bronchial brushing can add information to bronchoscopic examination by obtaining airway epithelial cells for cytology, to identify intracellular pathogens and to evaluate cilia. Studies have demonstrated the utility of bronchial brushings for the isolation, characterization and culture of primary epithelial cells from children with asthma. Endobronchial biopsies are used for histopathological and immunocytochemical analysis and microbiological culture. Biopsies are often performed to assess cilia function and architecture. In addition

    Full Text Available A aspiração de corpo estranho (ACE para o trato respiratório é um problema comum em pacientes pediátricos, em especial abaixo dos três anos de idade. Na avaliação radiológica inicial, cerca de 30% dos pacientes apresentam radiograma de tórax normal. A tomografia com broncoscopia virtual (BV pode auxiliar no diagnóstico precoce desse quadro e seu pronto manejo. O tratamento definitivo se dá com a retirada do corpo estranho através de broncoscopia rígida e mediante anestesia geral. O objetivo deste trabalho foi descrever o uso da BV na abordagem de dois pacientes com suspeita de ACE e realizar uma revisão da literatura sobre este tópico. Os dois pacientes tiveram início súbito de sintomas respiratórios e relato de tosse ou engasgo com alimentos antecedendo o quadro. Os pacientes foram submetidos à BV, e foi detectada a presença de corpo estranho endobrônquico em ambos os casos, com remoção posterior por broncoscopia rígida convencional em um caso. A BV é um método não-invasivo recente e com potencial para detectar a presença de corpo estranho na via respiratória em crianças. Em casos selecionados, BV pode auxiliar na localização correta do corpo estranho e até mesmo evitar o procedimento de broncoscopia rígida na ausência de corpo estranho.Foreign body aspiration (FBA into the tracheobronchial tree is a common problem in children, especially in those under three years of age.

    Mutations in the KRAS and TP53 genes have been found frequently in lung tumors and specimens from individuals at high risk for lung cancer and have been suggested as predictive markers for lung cancer. In order to assess the prognostic value of these two genes' mutations in lung cancer recurrence, we analyzed mutations in codon 12 of the KRAS gene and in hotspot codons of the TP53 gene in 176 bronchial biopsies obtained from 77 former lung cancer patients. Forty-seven patients (61.0%) showed mutations, including 35/77 (45.5%) in the KRAS gene and 25/77 (32.5%) in the TP53 gene, among them 13/77 (16.9%) had mutations in both genes. When grouped according to past or current smoking status, a higher proportion of current smokers showed mutations, in particular those in the TP53 gene (P = 0.07), compared with ex-smokers. These mutations were found in both abnormal lesions (8/20 or 40%) and histologically normal tissues (70/156 or 44.9%) (P = 0.812). They consisted primarily of G to A transition and G to T transversion in both the KRAS (41/56 or 73.2%) and TP53 (24/34 or 70.6%) genes, consistent with mutations found in lung tumors of smoking lung cancer patients. Overall, recurrence-free survival (RFS) among all subjects could be explained by age at diagnosis, tumor stage, tumor subtype, and smoking (P TP53 mutations were frequently detected in bronchial tissues of former lung cancer patients. However, the presence of mutation of bronchial biopsies was not significantly associated with a shorter RFS time. © 2016 Wiley Periodicals, Inc.

    Bronchoscopy remains a pivotal diagnostic and therapeutic intervention in pediatric patients undergoing lung transplantation (LTx). Whether performed as part of a surveillance protocol or if clinically indicated, fibre-optic bronchoscopy allows direct visualization of the transplanted allograft, and in particular, an assessment of the patency of the bronchial anastomosis (or tracheal anastomosis following heart-lung transplantation). Additionally, bronchoscopy facilitates differentiation of infective processes from rejection episodes through collection and subsequent assessment of bronchoalveolar lavage (BAL) and transbronchial biopsy (TBBx) samples. Indeed, the diagnostic criteria for the grading of acute cellular rejection is dependent upon the histopathological assessment of biopsy samples collected at the time of bronchoscopy. Typically, performed in an out-patient setting, bronchoscopy is generally a safe procedure, although complications related to hemorrhage and pneumothorax are occasionally seen. Airway complications, including stenosis, malacia, and dehiscence are diagnosed at bronchoscopy, and subsequent management including balloon dilatation, laser therapy and stent insertion can also be performed bronchoscopically. Finally, bronchoscopy has been and continues to be an important research tool allowing a better understanding of the immuno-biology of the lung allograft through the collection and analysis of collected BAL and TBBx samples. Whilst new investigational tools continue to evolve, the simple visualization and collection of samples within the lung allograft by bronchoscopy remains the gold standard in the evaluation of the lung allograft. This review describes the use and experience of bronchoscopy following lung transplantation in the pediatric setting.

    Full Text Available Background. Fluorescence bronchoscopy is one of the methods of the early detection of lung cancer that involves the large airways. The method is based on the detection of the altered autofluorescence of malignantly transformed tissue, and confirmed by biopsy and histopathologic examination. Method. Fluorescence bronchoscopy was performed in 18 patients, mean age of 51.2 years (male n=12, female n=6 due to the suspected lung cancer. Fluorescence bronchoscopy was performed using the Xillix LIFE-Lung System Vancouver, Canada. After conventional white-light bronchoscopy, the tracheobronchial tree was illuminated by blue light (442 nm using helium-cadmium laser, and the results of autofluorescence were classified into three classes. Normal mucosa was of green fluorescence (Class I abnormal mucosa was red or dark brown fluorescence (Class II and II, which was the indication for performing biopsy. Results. Normal endoscopy findings were established in 15 patients by conventional bronchoscopy. In the same group, by fluorescence bronchoscopy, Class I of fluorescence (normal finding was found in 9 patients, while Class II changes occured in 6 patients. Histopathologic analysis of bronchial mucosa with Class II changes was performed detecting planocellular carcinoma in situ in one patient. Tumor-like changes were detected in 3 patients by conventional bronchoscopy and were determined as Class III changes by fluorescence bronchoscopy. By the biopsy of these chages carcinoma was documented in 2 patients while in one patient metaplasia of epithelium and granulation tissue around aspirated foreign body was detected. Conclusion. Fluorescence bronchoscopy is one of the methods for detecting metaplasia, carcinoma in situ and cancerous changes of bronchial epithelium in the large airways. However, the high rate of falsely positive findings represents a limitation of this method.

    Matsumoto, Takeshi; Otsuka, Kojiro; Imai, Yukihiro; Tomii, Keisuke

    2016-04-01

    A 48-year-old man was referred for an abnormal shadow in his chest x-ray. Transbronchial needle aspiration cytology was performed at the mediastinal necrotic lymph node #7, and he was diagnosed as having small cell carcinoma. Fifteen days after bronchoscopy, sudden cardiac tamponade occurred and pericardial drainage suggested a diagnosis of bacterial pericarditis. He was successfully treated by drainage and administration of antibiotics. Complication of bacterial pericarditis associated with bronchoscopy is rare. However, physicians should watch for the appearance of this condition for up to 3 weeks after bronchoscopy, especially in cases with necrotic lymph nodes.

    2016-01-01

    Foreign body (FB) aspiration is commonly seen in children but less commonly in adolescents. Headscarf pin aspiration is common in Muslim girls, who inappropriately place the pins between their lips while securing the scarf on the head. Bronchoscopy is the treatment modality of choice, and surgery is rarely required. An 11-year-old girl was admitted as a case of accidental aspiration of headscarf pin. X-ray chest showed a radiopaque object in the left bronchus piercing the lung parenchyma. Computed tomography (CT) chest confirmed the diagnosis. The headscarf pin was removed by flexible bronchoscopy as the ear, nose, and throat (ENT) surgeon failed to remove it by rigid bronchoscopy. The FB was removed successfully and the patient was discharged home. Removal of a sharp pin by bronchoscopy is difficult, especially if it pierces the lung parenchyma. In our case, the pin was bent by forceps and then removed by a flexible bronchoscope, which requires a highly skilled professional. PMID:27578937

    Full Text Available Mucormycosis is a rare opportunistic infection usually associated with immunosuppression, diabetes mellitus or haematological malignancy. Herein, we report an unusual case of mucormycosis in a 46-yr-old male patient with diabetes presenting with an endotracheal mass obstructing the trachea and cartilage damage. Histological examination of the bronchoscopy biopsy specimens revealed invasive mucormycosis. The patient was treated with intravenous amphotericin B followed by removal of the lesion via bronchoscopy.

    1995-05-01

    We revised our own experience in 208 patients with pleural effusion to whom fiberoptic bronchoscopy was made in part of the diagnostic study. In our population the most frequent cause was neoplastic origen, observing that in 97 patients (46%), 60 of them were due to bronchogenic carcinoma. In relation to the presentation symptoms, just when haemoptysis was present bronchoscopy exhibited bigger diagnostic profitability (17 of 29), p < 0.001. There were 106 patients (51%) who had some or several parenchymatic injuries going with the pleural effusion. In this group, in 55 cases, fiberoptic bronchoscopy was useful to the diagnosis; on the contrary when the only radiologic abnormality was pleural effusion, 102 cases, in 96 of them the procedure was not diagnostic, p < 0.001. A close relationship was noticed between diagnostic profitability of bronchoscopy with the existence of pulmonary neoplasm; about the 61 diagnosed patients using bronchoscopy, 53 of them had bronchogenic carcinoma, p < 0.001. We conclude then in our experience bronchoscopy is useful to the diagnosis of pleural effusion if it goes with haemoptysis or parenchymatic lesions in the radioly. Its diagnostic profitability has close relationship with the existence of bronchogenic carcinoma.

Each patient was analyzed for age, sex, initial clinical diagnosis, nature and location of the foreign body, duration of symptoms between aspiration and bronchoscopy, radiological findings, results of bronchoscopic removal, complications of bronchoscopy and presence of foreign bodies in the airways. RESULTS: Thirty-four children, 20 (59% boys, ages ranging from nine months to nine years (median = 23 months. In 32 (94% children the foreign body was removed by rigid bronchoscope, and two resulted in thoracotomy. Foreign bodies were more frequent in children under three years of age (66%. A clinical history of foreign body inhalation was obtained in 27 (80% cases. Most of the foreign bodies removed were organic (65% and more frequently found in the right bronchial tree (59%. Foreign bodies were removed within 24 hours in 18 (53% cases. The most frequent radiographic findings were: unilateral air trapping, atelectasis and radiopac foreign body. Major bronchoscopy complications occurred in seven children (22%, and there were no deaths. CONCLUSIONS: More attention is necessary to the respiratory symptoms of aspirations, mainly in boys at early ages, with clinical history and compatible radiological findings. Most foreign bodies removed were of organic nature. In this case series, therapeutic rigid bronchoscopy was effective with few complications.

    Objective: To analyze the clinical features of lung cancer diagnosed by bronchoscopy. Methods:The clinical features of2168 patients with lung cancer diagnosed by bronchoscopy were retrospectively analyzed, including gender, age, pathological type, diseased region, manifestations under bronchoscopy and methods of drawing materials. Results:The ratio of male/female was 4.8:1 and the peak onset age was 60~69 years old. The major pathological type was squamous cell carcinoma (44.5%), then adenocarcinoma (25.9%) and small cell lung cancer (18.3%). The incidence of squamous cell carcinoma was the highest in males (50.6%), while that of adenocarcinoma in females (56.2%). The positive diagnostic rates of forceps biopsy, brush biopsy, bronchial alveolar lavage and transbronchial needle aspiration were 81.6%, 49.4%, 18.2% and 62.6%, respectively, whereas that of biopsy combined with brush biopsy came up to 89.0%. Conclusion: Bronchoscopy is an important method in diagnosis of lung cancer. Different ages and genders of patients with lung cancer have different onset, and the distribution of pathological types is diverse. Attaching more importance to bronchoscopy and improving biopsy technique can signiifcantly improve the diagnostic rate and provide reliable evidences for clinical treatment.

    Full Text Available Massive hemoptysis can be a life threatening condition and needs urgent treatment in lung cancer. In the fiberoptic bronchoscopy of a fifty-two-year-old who was admitted with hemoptysis, left upper lobe upper division orifice was seen totally obstructed with a submucosal infiltration. One hour after the mucosal biopsies, massive hemoptysis occurred. Urgent rigid bronchoscopy was performed. The left main bronchus was occluded by sterile gauze. After cleaning of the coagulum patient was intubated and charged to intensive care unit. The next day, rigid bronchoscopy was repeated and the bleeding was observed to continue from the left upper lobe. Removing the gauze, 14 × 10 × 10 mm silicon Y stent was inserted in the left main bronchus after adjustments were made. Bleeding was stopped after insertion of the stent and patient could be extubated. In this case a successful control of hemoptysis was sustained after insertion of a customized silicon stent was presented.

    Endobronchial ultrasound (EBUS) is now recommended as a standard procedure for in vivo verification of extraluminal diagnostic sites during cancer-staging bronchoscopy. Yet, physicians vary considerably in their skills at using EBUS effectively. Regarding existing bronchoscopy guidance systems, studies have shown their effectiveness in the lung-cancer management process. With such a system, a patient's X-ray computed tomography (CT) scan is used to plan a procedure to regions of interest (ROIs). This plan is then used during follow-on guided bronchoscopy. Recent clinical guidelines for lung cancer, however, also dictate using positron emission tomography (PET) imaging for identifying suspicious ROIs and aiding in the cancer-staging process. While researchers have attempted to use guided bronchoscopy systems in tandem with PET imaging and EBUS, no true EBUS-centric guidance system exists. We now propose a full multimodal image-based methodology for guiding EBUS. The complete methodology involves two components: 1) a procedure planning protocol that gives bronchoscope movements appropriate for live EBUS positioning; and 2) a guidance strategy and associated system graphical user interface (GUI) designed for image-guided EBUS. We present results demonstrating the operation of the system.

    Tracheobronchomalacia (TBM) is defined as an excessive collapse of the intrathoracic trachea. Bronchoscopy is the gold standard for diagnosing TBM; however it has major disadvantages, such as general anaesthesia. Cine computed tomography (CT) is a noninvasive alternative used to diagnose TBM, but its use in children is restricted by ionising radiation. Our aim was to evaluate the feasibility of spirometer-controlled cine magnetic resonance imaging (MRI) as an alternative to cine-CT in a retrospective study. 12 children with a mean age (range) of 12 years (7-17 years), suspected of having TBM, underwent cine-MRI. Static scans were acquired at end-inspiration and expiration covering the thorax using a three-dimensional spoiled gradient echo sequence. Three-dimensional dynamic scans were performed covering only the central airways. TBM was defined as a decrease of the trachea or bronchi diameter >50% at end-expiration in the static and dynamic scans. The success rate of the cine-MRI protocol was 92%. Cine-MRI was compared with bronchoscopy or chest CT in seven subjects. TBM was diagnosed by cine-MRI in seven (58%) out of 12 children and was confirmed by bronchoscopy or CT. In four patients, cine-MRI demonstrated tracheal narrowing that was not present in the static scans. Spirometer controlled cine-MRI is a promising technique to assess TBM in children and has the potential to replace bronchoscopy.

    BACKGROUND: The development of a fistula between the tracheobronchial tree and the gastric conduit post esophagectomy is a rare and often fatal complication. CASE PRESENTATION: A 68 year old man underwent radical esophagectomy for esophageal adenocarcinoma. On postoperative day 14 the nasogastric drainage bag dramatically filled with air, without deterioration in respiratory function or progressive sepsis. A fiberoptic bronchoscopy was performed which demonstrated a gastro-bronchial fistula in the posterior aspect of the left main bronchus. He was managed conservatively with antibiotics, enteral nutrition via jejunostomy, and non-invasive respiratory support. A follow- up bronchoscopy 60 days after the diagnostic bronchoscopy, confirmed spontaneous closure of the fistula CONCLUSIONS: This is the first such case where a conservative approach with no surgery or endoprosthesis resulted in a successful outcome, with fistula closure confirmed at subsequent bronchoscopy. Our experience would suggest that in very carefully selected cases where bronchopulmonary contamination from the fistula is minimal or absent, there is no associated inflammation of the tracheobronchial tree and the patient is stable from a respiratory point of view without evidence of sepsis, there may be a role for a trial of conservative management.

It results from cartilage deficiency and bronchomalacia causing distal air trapping and respiratory distress. Acquired forms are usually associated with chronic lung disease or endobronchial obstruction such as mucus plugging. "nWe report a pedunculated endobronchial polyp in a 18-month-old infant causing hyperinflation of the left upper lobe, which is the most common site of CLE, and presented with sudden respiratory distress. The polyp was seen in the left upper bronchus at bronchoscopy. The imaging features of this case in CXR and CT scan will be shown and the possible etiological links with mechanical bronchial obstruction will be discussed. "nWe also emphasize the value of bronchoscopy prior to lobectomy in cases of congenital lobar emphysema (CLE.

    Endobronchial cartilage rupture is a rare clinical condition, which can present in patients with severe emphysema with sudden onset shortness of breath. We present a case of a 62-year-old male who presented to our emergency department with sudden onset shortness of breath. Chest X-ray showed lung hyperinflation and a right lung field vague small density. Chest Computed Tomography confirmed the presence of right middle lobe collapse. Bronchoscopy revealed partial right middle lobe atelectasis and an endobronchial cartilage rupture. Endobronchial cartilage rupture is a rare condition that can present as sudden onset shortness of breath due to lobar collapse in patients with emphysema and can be triggered by cough. Bronchoscopic findings include finding a collapsed lung lobe and a visible ruptured endobronchial cartilage. A high index of suspicion, chest imaging, and early bronchoscopy can aid in the diagnosis and help prevent complications. PMID:27525149

    We present a case of 63-year-old man who was referred to the emergency department with a right-sided pneumothorax. He had a history of spontaneous pneumothorax for 2 times. The chest computed tomographic scan showed tracheobronchomegaly with an increase in the diameter of the trachea and right and left main bronchus. Fiberoptic bronchoscopy revealed enlarged trachea and both main bronchus with diverticulas. These findings are consistent with a diagnosis of Mounier-Kuhn syndrome. Mounier-Kuhn syndrome is a rare clinical and radiologic condition. It is characterized by a tracheal and bronchial dilation. Diagnosis is made by computed tomography and bronchoscopy. Mounier-Kuhn syndrome should be kept in mind in the differential diagnosis of recurrent spontaneous pneumothorax.

    The disposable plastic beverage cup is not usually regarded as hazardous to young children. Certain varieties of these products however, are manufactured from a brittle, clear plastic that easily cracks and fragments. While most conscientious parents keep their children safe from peanuts, balloons, and other known choking hazards, a child can surreptitiously bite a cup edge and aspirate the fragment. We report two cases of foreign body aspiration involving clear plastic cups that went undetected one of which remained 21 months following a negative rigid bronchoscopy. Diagnostic difficulties are related to the transparency and radiolucency of these objects. When suspicious of foreign body aspiration in children, otolaryngologists should inquire about the availability of clear plastic cups in the household and be mindful of the diagnostic pitfalls. Further investigations including CT scanning and repeat bronchoscopy may be helpful in cases of suspected missed foreign bodies. An educational campaign aimed at prevention and placement of product package warning labels should be established.

  18. Unusual cause of respiratory distress misdiagnosed as refractory asthma

    Full Text Available We report a young lady, who was labeled as a case of refractory asthma for a few years, based on history of shortness of breath on minimal exertion, noisy breathing and normal chest radiograph. Repeated upper airway exam by an otolaryngologist and computerized tomography scan, were normal. On presentation to our hospital, she was diagnosed to have fixed upper airway obstruction, based on classical flow-volume loop findings. Fibroptic bronchoscopy revealed a web-shaped subglottic stenosis. The histopathology of a biopsy taken from that area, showed non-specific inflammation. No cause for this stenosis could be identified. The patient was managed with rigid bronchoscopy dilatation, without recurrence. We report this case as idiopathic subglottic stenosis, that was misdiagnosed as refractory bronchial asthma, stressing the importance of performing spirometry in the clinic.

    The authors describe the case of a man, 46 years old, former smoker, former bird breeder, followed in the service of Imunoallergology for bronchospasm without response to the treatment. After experiencing an hemoptysis he was admitted in our service. He was submitted to many exams, which include a flexible bronchoscopy. This technique allows the identification of an endobronquial necrotic mass, which almost obstructed the main right bronchus. In order to obtain a bigger and more representative sample a rigid bronchoscopy was performed. This technique showed a broncholith, which was partially removed, and a bronchial fistula. Actually he is assimptomatic and under annual surveillance. First described for Aristoteles, the broncholithiasis is defined by the presence of stones in the bronchial tree. It is a very rare pathology, with a variable clinical expression, which must be considered whenever there is respiratory complaints in association with hilar or mediastinic calcifications.

    Full Text Available Here, we report a case of 57-year-old previously healthy man with six-months medical history of significant chronic cough and recurring episodes of fever. Cytology, bacteria, fungi and acid fast bacilli in the sputum were negative. CT scan, initially interpreted as suspected lung cancer, detected by chest x-ray, revealed pneumonia. Bronchoscopy is frequently necessary for the diagnosis as well as the treatment as a routine practice and in this case was applied. Our patient underwent to fiberoptic rigid bronchoscopy in the right upper lobe in general anaesthesia. Unexpectedly, a vegetal FB, Medlar's core instead a tumor, was removed. After two-months follow-up the patient was found healthy without any old or other symptoms.

    2008-01-01

    Fibered confocal fluorescence microscopy (FCFM) is a new technique that can be used during a bronchoscopy to analyze the nature of the human bronchial and alveolar mucosa fluorescence microstructure. An endoscopic fibered confocal fluorescence microscopy system with spectroscopic analysis capability was developed allowing real-time, simultaneous images and emission spectra acquisition at 488 nm excitation using a flexible miniprobe that could be introduced into small airways. This flexible 1.4 mm miniprobe can be introduced into the working channel of a flexible endoscope and gently advanced through the bronchial tree to the alveoli. FCFM in conjunction with bronchoscopy is able to image the in vivo autofluorescence structure of the bronchial mucosae but also the alveolar respiratory network outside of the usual field of view. Microscopic and spectral analysis showed that the signal mainly originates from the elastin component of the bronchial subepithelial layer. In non smokers, the system images the elastin...

    Tracheobronchomalacia (TBM) is defined as an excessive collapse of the intrathoracic trachea. Bronchoscopy is the gold standard to diagnose TBM, but bronchoscopy has major disadvantages, such as general anaesthesia. Cine-CT is a non-invasive alternative to diagnose TBM, but its use in children...... is restricted by ionizing radiation. Our aim was to evaluate the feasibility of spirometer-controlled cine-MRI as alternative to cine-CT in a retrospective study.12 children (mean 12 years, range 7-17), suspected to have TBM, underwent cine-MRI. Static scans were acquired at end-inspiration and expiration...... covering the thorax using a 3D SPGR sequence. 3D-Dynamic-scans were performed covering only the central airways. TBM was defined as a decrease of the trachea or bronchi diameter greater than 50% at end-expiration in the static and dynamic scans.The success rate of the cine-MRI protocol was 92%. Cine...

    Positron emission tomography (PET) and X-ray computed tomography (CT) serve as major diagnostic imaging modalities in the lung-cancer staging process. Modern scanners provide co-registered whole-body PET/CT studies, collected while the patient breathes freely, and high-resolution chest CT scans, collected under a brief patient breath hold. Unfortunately, no method exists for registering a PET/CT study into the space of a high-resolution chest CT scan. If this could be done, vital diagnostic information offered by the PET/CT study could be brought seamlessly into the procedure plan used during live cancer-staging bronchoscopy. We propose a method for the deformable registration of whole-body PET/CT data into the space of a high-resolution chest CT study. We then demonstrate its potential for procedure planning and subsequent use in multimodal image-guided bronchoscopy.

  5. Outcomes after Bronchoscopic Procedures for Primary Tracheobronchial Amyloidosis: Retrospective Study of 6 Cases

    2012-01-01

    Full Text Available Respiratory amyloidosis is a rare disease which refers to localized aberrant extracellular protein deposits within the airways. Tracheobronchial amyloidosis (TBA refers to the deposition of localized amyloid deposits within the upper airways. Treatments have historically focused on bronchoscopic techniques including debridement, laser ablation, balloon dilation, and stent placement. We present the outcomes after rigid bronchoscopy to remove the amyloid protein causing the airway obstruction in 6 cases of tracheobronchial amyloidosis. This is the first report of primary diffuse tracheobronchial amyloidosis in our department; clinical features, in addition to therapy in the treatment of TBA, are reviewed. This paper shows that, in patients with TBA causing airway obstruction, excellent results can be obtained with rigid bronchoscopy and stenting of the obstructing lesion.

    We describe a case of near-fatal asthma requiring extracorporeal membrane oxygenation (ECMO). The patient presented with severe respiratory distress, which was not responsive to conventional pharmacological therapy. The patient also failed to respond to mechanical ventilation and thus was placed on venovenous ECMO for temporary pulmonary support. A fiberoptic bronchoscopy revealed that large amounts of thick bronchial secretions had occluded the main bronchus, which suggested plastic bronchitis secondary to asthma. Aggressive airway hygiene with frequent bronchoscopies and application of biphasic cuirass ventilation for facilitation of secretion clearance were performed to improve the patient's respiratory status. The patient achieved a full recovery and suffered no neurological sequelae. This case illustrates that aggressive pulmonary hygiene with ECMO is a useful therapy for patients with asthma-associated plastic bronchitis.

    2017-01-01

    A 23-year-old man who had previously undergone allogeneic hematopoietic stem cell transplantation (allo-HSCT) for severe aplastic anemia was diagnosed with invasive laryngeal-tracheobronchial-pulmonary aspergillosis after presenting with a persistent dry cough at six months post-transplantation based on the findings of laryngoscopy and fiberoptic bronchoscopy. A fiberoptic bronchoscope was used to remove the obstructive material from the patient's airway and posaconazole plus caspofungin were administered to successfully to treat the patient. Our report suggests that laryngoscopy and fiberoptic bronchoscopy should be considered as alternative approaches to the diagnosis and treatment of allo-HSCT recipients with persistent respiratory symptoms when invasive laryngeal aspergillosis and invasive tracheobronchial aspergillosis are suspected.

    Teflon-coated pledgeted sutures can be used to reinforce the bronchial anastomosis site following a pulmonary resection in order to prevent bronchopleural fistula formation. The authors describe the case of a 42-year-old woman with recurrent haemoptysis secondary to the erosion of a pledgeted suture through the distal trachea. The pledgeted suture was used to reinforce a defect in the wall of the distal trachea after a right upper lobectomy for stage 2a squamous cell carcinoma. Surgically, a completion pneumonectomy with carinal reconstruction was thought necessary to treat the haemoptysis. Given her age and potential surgical morbidities, the decision was made to perform serial bronchoscopies with careful pruning and eventual removal of the pledget by using the cryoprobe and a flexible scissors. This resulted in the eventual removal of the suture. Follow-up bronchoscopy 4 weeks postremoval demonstrated no residual defect on the airway wall.

    Reported here are 2 patients with connective tissue disease who developed pulmonary nocardiosis. Case 1 involved a 73-year-old man with malignant rheumatoid arthritis treated with prednisolone 25 mg/day. Chest X-rays revealed a pulmonary cavity and bronchoscopy detected Nocardia species. The patient was successfully treated with trimethoprim/sulfamethoxazole. Case 2 involved a 41-year-old woman with systemic lupus erythematosus. The patient received remission induction therapy with 50 mg/day of prednisolone and tacrolimus. Six weeks later, a chest CT scan revealed a pulmonary cavity; bronchoscopy resulted in a diagnosis of pulmonary nocardiosis. The patient had difficulty tolerating trimethoprim/sulfamethoxazole, so she was switched to and successfully treated with imipenem/cilastatin and amikacin.

    Full Text Available Traumatic neuromas are uncommon and benign lesions arising from a peripheral nerve injury during surgery. Here we describe a case with histopathologic features of both a traumatic neuroma and neurofibroma in a patient without integumentary physical exam findings nor prior surgical history. A 54 year old male was admitted for surgical debridement of a foot ulcer. During pre-operative evaluation and review of imaging multiple CT scans revealed a stable, 4 mm endobronchial lesion in the left lower lobe. Given history of nicotine abuse, bronchoscopy was performed. Bronchoscopy showed a pearly, polypoid lesion. Histopathological results showed strong positivity for S-100 protein and spindle cell proliferation. Repeat CT chest showed no new lesions in the bronchial tree. The rarity of this case is noted not only by the limited number of bronchial neurogenic tumors, but the combined features in this case of a traumatic neuroma and neurofibroma which has not been described.

    Objective Bronchoscopy has been extensively used in the diagnosis of respiratory diseases, and par-ticularly, malignant diseases. However, endoscopists do not normal y perform bronchoscopic biopsy in case lesions are undetected via bronchoscopy. The aim of this study was to evaluate whether performing bron-choscopic biopsy could be established in the diagnosis of lung cancer in case of endobronchial abnormali-ties undetectable to the naked eye. Methods We retrospectively analyzed 109 cases between January 2008 and December 2012. The in-clusion criteria were confirmed lung cancer diagnosis, transbronchial biopsy performed in the absence of visible endobronchial manifestations, brushing, and bronchoalveolar lavage (BAL) according to the images obtained from high-resolution computed tomography (HRCT). Data regarding age, sex, pathology, tumor stage; the method of diagnosis; location of primary lesion (central, peripheral, or intermediate); tumor size, mediastinal lymph node metastasis, and the serum carcinoembryonic antigen (CEA) value were col ected. The Pearson chi-square test or Fisher’s exact and McNemar tests were used in the univariate analysis. Results Among the 109 patients, the diagnosis of 37 (33.9%) patients was confirmed through bronchos-copy. Brushing and BAL had higher positive detection rates than biopsy (P = 0.004). There were no dif er-ences in the positive detection rates between the sex, pathology, lesion location, tumor size, lymph node metastasis, and the serum CEA value (P > 0.05 for al groups). Conclusion Despite the normal appearance of the endobronchial manifestations, lesions undetectable by bronchoscopy could be indicated. Therefore, we suggest performing bronchoscopic biopsy and that brushing and BAL might increase the positive detection rate of bronchoscopic examination.

    A baby presented at term with respiratory distress was managed with extracorporeal membrane oxygenation. Bronchoscopy revealed tracheal hypoplasia, complete tracheal rings, and agenesis of the right main bronchus. Echocardiography showed a left pulmonary arterial sling arising from the proximal part of the right pulmonary artery. Cardiac catheterization demonstrated abnormal pulmonary vasculature in the left lung which would have prevented survival, even after surgical repair. Diagnostic catheterization was important in delineating the anatomy, and aided in the decision not to proceed with surgical repair.

    Full Text Available Background: There is paucity of data regarding the morbidity and mortality of rigid bronchoscopy in children for foreign body (FB retrieval from India. The aim was to audit data regarding anaesthetic management of rigid bronchoscopy in children and associated morbidity and mortality. Materials and Methods: Hospital records of all patients below 18 years of age undergoing rigid bronchoscopy for suspected FB aspiration (FBA between January 1, 2002 and December 31, 2011 were audited to assess their demographic profile, anaesthetic management, complications, and postoperative outcomes. The children were divided into early and late diagnosis groups depending on whether they presented to the hospital within 24 hours of FBA, or later. Results: One hundred and forty children, predominantly male (75%, with an average age of 1-year and 8 months, presented to our hospital for rigid bronchoscopy during the study period. Majority of children presented in the late diagnosis group (59.29% vs. 40.71%. The penetration syndrome was observed in 22% of patients. Majority of patients aspirated an organic FB (organic: Inorganic FB = 3:1, with peanuts being the most common (49.28%. A significantly higher number of children presented with cough (P = 0.0001 and history of choking (P = 0.0022 in the early diagnosis group and crepitations (P = 0.0011 in the late diagnosis group. Major complications included cardiac arrest (2.1%, pneumothorax (0.7%, and laryngeal oedema (9.3%. The average duration of hospitalization in our series was 3.08 ± 0.7 days. Conclusions: Foreign body aspiration causes considerable morbidity, especially when diagnosis is delayed.

  3. SHOX2 DNA Methylation is a Biomarker for the diagnosis of lung cancer based on bronchial aspirates

    Directory of Open Access Journals (Sweden)

    Liloglou Triantafillos

    2010-11-01

    Full Text Available Abstract Background This study aimed to show that SHOX2 DNA methylation is a tumor marker in patients with suspected lung cancer by using bronchial fluid aspirated during bronchoscopy. Such a biomarker would be clinically valuable, especially when, following the first bronchoscopy, a final diagnosis cannot be established by histology or cytology. A test with a low false positive rate can reduce the need for further invasive and costly procedures and ensure early treatment. Methods Marker discovery was carried out by differential methylation hybridization (DMH and real-time PCR. The real-time PCR based HeavyMethyl technology was used for quantitative analysis of DNA methylation of SHOX2 using bronchial aspirates from two clinical centres in a case-control study. Fresh-frozen and Saccomanno-fixed samples were used to show the tumor marker performance in different sample types of clinical relevance. Results Valid measurements were obtained from a total of 523 patient samples (242 controls, 281 cases. DNA methylation of SHOX2 allowed to distinguish between malignant and benign lung disease, i.e. abscesses, infections, obstructive lung diseases, sarcoidosis, scleroderma, stenoses, at high specificity (68% sensitivity [95% CI 62-73%], 95% specificity [95% CI 91-97%]. Conclusions Hypermethylation of SHOX2 in bronchial aspirates appears to be a clinically useful tumor marker for identifying subjects with lung carcinoma, especially if histological and cytological findings after bronchoscopy are ambiguous.

    The aim of this study was to assess radiomorphologic and clinical features of tracheal rupture due to blunt chest trauma. From 1992 until 1998 the radiomorphologic and clinical key findings of all consecutive tracheal ruptures were retrospectively analyzed. The study included ten patients (7 men and 3 women; mean age 35 years); all had pneumothoraces which were persistent despite suction drainage. Seven patients developed a pneumomediastinum as well as a subcutaneous emphysema on conventional chest X-rays. In five patients, one major hint leading to the diagnosis was a cervical emphysema, discovered on the lateral cervical spine view. Contrast-media-enhanced thoracic CT was obtained in all ten cases and showed additional injuries (atelectasis n = 5; lung contusion n = 4; lung laceration n = 2; hematothorax n = 2 and hematomediastinum n = 4). The definite diagnosis of tracheal rupture was made by bronchoscopy, which was obtained in all patients. Tracheal rupture due to blunt chest trauma occurs rarely. Key findings were all provided by conventional chest X-ray. Tracheal rupture is suspected in front of a pneumothorax, a pneumomediastinum, or a subcutaneous emphysema on lateral cervical spine and chest films. Routine thoracic CT could also demonstrate these findings but could not confirm the definite diagnosis of an tracheal rupture except in one case; in the other 9 cases this was done by bronchoscopy. Thus, bronchoscopy should be mandatory in all suspicious cases of tracheal rupture and remains the gold standard. (orig.)

    Background There are currently many techniques and devices available for the diagnosis of lung cancer. However, rapid on-site diagnosis is essential for early-stage lung cancer, and in the current work we investigated a new diagnostic illumination nanotechnology. Methods Tissue samples were obtained from lymph nodes, cancerous tissue, and abnormal intrapulmonary lesions at our interventional pulmonary suites. The following diagnostic techniques were used to obtain the samples: endobronchial ultrasound bronchoscopy; flexible bronchoscopy; and rigid bronchoscopy. Flexible and rigid forceps were used because several of the patients were intubated using a rigid bronchoscope. In total, 30 tissue specimens from 30 patients were prepared. CytoViva® illumination nanotechnology was subsequently applied to each of the biopsy tissue slides. Results A spectral library was created for adenocarcinoma, epidermal growth factor receptor mutation-positive adenocarcinoma, squamous cell carcinoma, usual interstitial pneumonitis, non-specific interstitial pneumonitis, typical carcinoid tumor, sarcoidosis, idiopathic pulmonary fibrosis, small cell neuroendocrine carcinoma, thymoma, epithelioid and sarcomatoid mesothelioma, cryptogenic organizing pneumonia, malt cell lymphoma, and Wegener’s granulomatosis. Conclusion The CytoViva software, once it had created a specific spectral library for each entity, was able to identify the same disease again in subsequent paired sets of slides of the same disease. Further evaluation of this technique could make this illumination nanotechnology an efficient rapid on-site diagnostic tool. PMID:24285923

    This study was to re-evaluate inhalation injury as a prognostic factor in burn patients and to determine the factors that should be considered when refining the definition of inhalation injury. A total of 192 burn patients (152 men, 40 women; mean age, 46.1±13.8 years) who were suspected to have an inhalation injury and underwent bronchoscopy between January 2010 and June 2012 were included in this prospective observational study. All patients underwent bronchoscopy within 24h of sustaining the burn. The bronchoscopic findings were classified as normal, mild, moderate, and severe. Mechanical ventilation was administered, when required. Age, percentage of TBSA burned, ABSI score, requirement of mechanical ventilation and PF ratio, but not inhalation injury, COHb level, and bronchoscopic grades, significantly differed between the survivors and non-survivors (pburns. Other components such as severity of inhalation injury determined using bronchoscopy, and administration of mechanical ventilation might help predict the morbidity and mortality of burn patients with inhalation injury and all of the factors should be considered when the definition of inhalation injury is refined.

This study aimed to report the characteristics of thetraining in pulmonary endoscopy provided in Greece and to evaluatequantitive and qualitive parameters of interventional endoscopyperformance among Greek pneumonologists. METHOD. A speciallydesigned questionnaire was completed by 171 specialists and fellowsin pulmonology and the responses were analyzed. RESULTS. An agedifference in endoscopic skills was observed; 97% of the respondentsaged 50 years (p=0.016. In spite of a high rateof training, 65% of respondents reported performing less than 50bronchoscopies per year. In addition, 21% were familiar with thetechnique of transbronchial needle aspiration (ΤΒΝΑ, but only 19%of them performed over 30 procedures per year. Other advanceddiagnostic techniques including endobronchial ultrasound (EBUS,auto-fluorescence and medical thoracoscopy are performed by asmall minority of pulmonologists while therapeutic techniques (i.e.rigid bronchoscopy, electrocautery, cryotherapy and laser therapyby very few (5-12%. The majority of respondents would welcomeadditional training, not only in advanced interventional techniquesbut also in standard bronchoscopy; 94% agreed that they wouldbenefit from the publication of practice guidelines on endoscopictechniques, and 71% supported the instruction in endoscopy ofall pulmonologists during their fellowship. CONCLUSIONS. Theendoscopic training provided to Greek pneumonologists could beimproved considerably and initiatives should be taken in order toupgrade and unify both the teaching of endoscopic techniques andthe services provided.

    Introduction Our motivation is increased bronchoscopic diagnostic yield and optimized preparation, for navigated bronchoscopy. In navigated bronchoscopy, virtual 3D airway visualization is often used to guide a bronchoscopic tool to peripheral lesions, synchronized with the real time video bronchoscopy. Visualization during navigated bronchoscopy, the segmentation time and methods, differs. Time consumption and logistics are two essential aspects that need to be optimized when integrating such technologies in the interventional room. We compared three different approaches to obtain airway centerlines and surface. Method CT lung dataset of 17 patients were processed in Mimics (Materialize, Leuven, Belgium), which provides a Basic module and a Pulmonology module (beta version) (MPM), OsiriX (Pixmeo, Geneva, Switzerland) and our Tube Segmentation Framework (TSF) method. Both MPM and TSF were evaluated with reference segmentation. Automatic and manual settings allowed us to segment the airways and obtain 3D models as well as the centrelines in all datasets. We compared the different procedures by user interactions such as number of clicks needed to process the data and quantitative measures concerning the quality of the segmentation and centrelines such as total length of the branches, number of branches, number of generations, and volume of the 3D model. Results The TSF method was the most automatic, while the Mimics Pulmonology Module (MPM) and the Mimics Basic Module (MBM) resulted in the highest number of branches. MPM is the software which demands the least number of clicks to process the data. We found that the freely available OsiriX was less accurate compared to the other methods regarding segmentation results. However, the TSF method provided results fastest regarding number of clicks. The MPM was able to find the highest number of branches and generations. On the other hand, the TSF is fully automatic and it provides the user with both segmentation of the

    The purpose of this study is to report the outcome of using expandable metallic stent in the management of malignant tracheobronchial stenosis with dyspnea. Under fluoroscopic and bronchoscopic guidance, seven patients with malignant airway stenosis were treated with ten expandable metallic stents. The cause of stenosis was metastasis from esophageal cancer in five patients, recurrent adenoid cystic carcinoma of the trachea in one, and primary lung cancer in one. The major sites of obstruction were the trachea in four patients, the left main bronchus in one, the trachea and left main bronchus in one, and the trachea and both bronchi in one. Chest radiography (n=7), bronchoscopy (n=5), pulmonary function test (PFT)(n=3), and spirometry(n=1) were performed before and after stent placement. In all seven patients, the stent was successfully placed at the lesion sites and dyspnea began to improve immediately. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After the procedure, chest radiography and bronchoscopy showed an increase in airway diameter. After stent placement, forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) improved 53% and 56%, respectively. Peak flow velocity also changed from 46 L/min to 200 L/min. During median follow-up of 67 (41-1565) days, one stent migration occurred. In one patient, proximal tumor overgrowth occurred, and in one, tumor ingrowth was treated with balloon dilatation. For in the palliative treatment of malignant tracheobronchial stenosis with dyspnea, placement of expandable metal stents is safe and effective. (author). 21 refs., 1 tabs., 3 figs.

    Objective: To describe the clinical manifestations and bronchoscopic treatment of foreign body aspiration in children under 14 years of age, correlating the clinical aspects with the bronchoscopic findings. Methods: A retrospective, descriptive study analyzing data related to children under 14 years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. Results: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age), 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%), auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%), and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts). In the follow-up period, 29% presented complications (most commonly pneumonia), which were found to be associated with longer aspiration time (p = 0.03). Mechanical ventilation was required in 7 children (10.1%), and multiple bronchoscopies were performed in 5 (7.2%). Conclusions: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention at children younger than three years of age. (author)

    Transbronchial needle aspiration(TBNA) is able to provide definitive answers for a wide variety of pulmonary benign and malignant diseases including infectious diseases,cystic lesions, granulomatous diseases, pulmonary and mediastinal mass, etc. It's proved particularly revolutionary to stage bronchogenic carcinoma during routine flexible bronchoscopy. What's more, TBNA is an extremely safe procedure with no reported major complications. This review introduces the techniques about identifying the target, obtaining the specimen and preparing and interpreting the specimen when conducting TBNA. The complications, a through unusual, and major limitations are also touched in this review.

    Full Text Available Pneumomediastinum (PM is defined as the presence of gas or free air in mediastinum. Pneumomediastinum may ocur either by trauma or spontaneously. Traumatic PM is frequently seen after blunt thoracic trauma, head trauma, after endoscopy-bronchoscopy (osephagus perforation, tracheobronchial injury and due to mechanical ventilation. Pneumomediastinum after blunt trauma is a lethal injury that generally occurs in adults with concomittant injuries such as rib fractures, hemo-pneumothorax and thoracic vascular injuries after high-energy traumas. We represent case report of a late onset isolated traumatic PM in a child and aim to underline the difficulty and importance of diagnosis of this lethal injury in the emergency department.

    Gastric cancer frequently presents intraperitoneal spread. Distant metastasis are rare. The authors describe a case of a 47-year-old white man, long-term cigarette smoker, who had a right upper lobe mass seen on plain films and computed tomography of the chest. A gastric adenocarcinoma was concomitantly diagnosed by endoscopic examination. A bronchoscopy guided biopsy showed that the lung mass was in fact a metastasis from gastric adenocarcinoma. In this article, the imaging findings of gastric cancer and the patterns of dissemination to other organs are reviewed. (author)

    We have selected four papers which brought major, new contributions to pulmonary medicine over the last year. These publications address following issues: The effect of low-dose CT-screening on lung cancer mortality; treatment of lung emphysema by bronchoscopy with endobronchial valves drainage of pleural infections with combined fibrinolytic agent and desoxyribonuclease; and long-term treatment of COPD with azithromycin. Each of these studies has brought novel and relevant information. It is too early to say that current practice has to be changed following these studies. However, they certainly open from now new diagnostic and therapeutic considerations on a case by case basis.

    We discuss here three recent applications of high technology in pulmonary medicine. GeneXpert has considerably improved the diagnosis of active tuberculosis. However, the test has also its limits so that clinical assessment, radiology, and sputum microscopy remain fundamental. Treatment of severe emphysema by lung volume reduction is no longer confined to surgical approach, but is now possible by bronchoscopy. Implantation of Nitinol coils in the most diseased parts of the emphysematous lung is a promising technique. Finally, several clinical trials on bronchial thermoplasty have been reported for intractable asthma. The recent publication of the long term effects of this technique is the occasion to update on this matter.

    In the last decade, endobronchial ultrasound (EBUS) has evolved into an important tool for diagnostic bronchoscopy in daily practice. EBUS has established as a standard for the diagnosis of hilar or mediastinal lymphadenopathy, as a guidance technique for peripheral pulmonary lesions and for the evaluation of tumor involvement of the tracheobronchial wall or mediastinum. In the meantime, EBUS has also taken a significant role in mediastinal staging in lung cancer patients. However, EBUS plays not only a role in the diagnosis of malignancies, it is also important for the diagnosis of benign disorders.

    The diagnostic value of the CD4 cell counts and the HIV p24 antigen were evaluated in a consecutive series of 105 HIV-infected patients experiencing 128 episodes of pulmonary symptoms which required bronchoscopy. One-third of patients with opportunistic infection (OI) had CD4 counts greater than 0....... In conclusion, the CD4 cell counts and the presence of p24 antigen in serum had a very limited predictive value for the presence of OI in HIV-infected patients with pulmonary symptoms....

    Congenital tracheo-or-bronchobiliary fistula or congenital he-patopulmonary fistula is a rare malformation with high morbidity and mortality if the diagnosis is not made early. The tracheo-or-bronchobiliary fistula is a communication between the respiratory (trachea or bronchus) and biliary tract. To date, only 35 cases have been published worldwide. We report a case of a neonate with right pneumonia and bilious fluid in the endotracheal tube. Diagnosis was made using bronchoscopy with fluoroscopy. Videothoracoscopy was used to remove the bronchobiliary fistula. Subsequently, a left he-patectomy with Roux-en-Y biliary-digestive anastomosis was performed as bile ductus hypoplasia was present.

    X-linked agammaglobulinemia (XLA) is caused by mutation in the gene coding for Bruton’s tyrosine kinase (BTK), which impairs peripheral B cell maturation and hypogammaglobulinemia. In this report, we present a case of XLA in a 22-year-old adult male. Genetic testing revealed a novel mutation located at the conserved region (c.383T>C). The patient had a history of recurrent respiratory tract infection which eventually progressed to chronic type II respiratory failure. Several pathogenic bacteria were isolated on culture of respiratory secretions obtained on bronchoscopy. The patient improved on treatment with antibiotics. PMID:27867589

    Diffuse pulmonary lymphangiomatosis (DPL) is a rare disease that is characterized by diffuse proliferation of abnormal pulmonary lymphatic channels. DPL occurs mostly in children and young adults and often undergoes a progressive clinical course, eventually causing deterioration of the lung. Both the clinical diagnosis and treatment of DPL remain a challenge. Here, we report a case of DPL in a 53-year-old Chinese woman with comprehensive investigations including pulmonary function tests, computer tomography (CT), bronchoscopy and histological examination of the lung biopsy, and review the literature.

    We experienced a rare case of an endobronchial primitive neuroectodermal tumor of the left main bronchus. Initially we suspected pneumothorax caused by a collapsed left upper lobe and an air-entrapped lower lobe. After tube thoracostomy, the pneumothorax persisted without air leakage. A tumor was detected at the left main bronchus on computed tomography and bronchoscopy, and diagnosed pathologically as small cell lung cancer. Under the presumed diagnosis of limited-stage small cell lung cancer, we performed a left pneumonectomy. The tumor was eventually identified pathologically as a primitive neuroectodermal tumor. Although adjuvant chemoradiotherapy was not performed, no recurrence was observed.

    We describe an immunocompetent child with bronchial fungus following foreign body aspiration. A two-year-old male presented with cough. Workup revealed air trapping and bronchoscopy showed aspirated foreign material in the right mainstem bronchus. Histopathology revealed fungal organisms suggestive of Aspergillus within an ulcer of the adjacent bronchial mucosa. Foreign body aspiration has been posited as a nidus for aspergilloma formation but is not yet described in the available English-language pediatric literature. Here, the foreign body provided a site for fungal growth in the bronchus of an otherwise healthy child. This case suggests that bronchial foreign body may pose risk of fungal colonization even in immunocompetent children.

    Full Text Available Given that Churg-Strauss syndrome is a systemic small-vessel vasculitis, it is not usually considered in patients who present with massive hemoptysis, which is typically caused by bronchiectasis, cancer or, in some cases, aberrant bronchial arteries. This article, however, describes a novel case involving a 50-year-old Churg-Strauss patient who presented with sudden-onset massive hemoptysis. Details of the physical examination, laboratory investigations and several imaging studies, including computed tomography, bronchoscopy and three-dimensional imaging, are presented.

    A 4 year old tracheostomy dependent girl with Pfeiffer syndrome was noted on bronchoscopy to have a pulsatile tracheostomal mass. CT chest angiography was consistent with the innominate artery crossing anterior to the trachea and superior to the sternal notch. The patient underwent reimplantation of the innominate artery via a median sternotomy approach. Tracheoinnominate fistula is a potentially devastating complication of tracheostomy. We report discovery of a near tracheoinnominate fistula in order to highlight the importance of regular interval surveillance endoscopy in tracheostomy dependent children and to discuss a preventative surgical intervention employed in prevention of this potentially devastating complication.

    Craniofacial abnormalities in pediatric population fall under the category of expected case of difficult airway. We present here a case of large maxillary tumor in a 9-year-old girl where the relative difficulty was further compounded due to her noncooperation which was again expected from a child. Local anesthetic topicalization of airway followed by slow inhalational induction with gradually increasing sevoflurane, while maintaining her spontaneous breathing, we secured her airway using fiber optic bronchoscopy. The surgery and the extubation went uneventful. In conclusion a planned airway management using fiber optic bronchoscope after airway topicalization and sevoflurane induction is the ideal technique in an expected case of difficult pediatric airway.

    A 2-yr-old female captive-born Hoffmann's two-toed sloth (Choloepus hoffmanni) presented with respiratory disease. A severe inspiratory dyspnea with nasal congestion was observed with open-mouthed breathing and bilateral mucopurulent nasal exudate. Despite initial treatment with broad-spectrum antimicrobial therapy and anti-inflammatory and supportive care, the dyspnea persisted. The animal was anesthetized for bronchoscopy to obtain a deep tracheal sample. Based on culture of Bordetella bronchiseptica and sensitivity, a combination of systemic enrofloxacin, dexamethasone, and coupage with nebulization of saline, gentamicin, and albuterol as well as supportive care resulted in full recovery after 6 weeks of treatment.

    The occurrence of foreign body is uncommon in youths and adults. We report here a case of 16-year-old boy who inhaled a foreign body which was overlooked for 6 months. The patient suffered productive cough and received antibiotic treatment for 10 days. But the symptoms did not improve. Chest radiography and CT scan revealed a 1-cm-long needle-like foreign object in the right inferior lobar bronchus. Wedge resection of lung was finally performed because of severe hemorrhage caused by prior bronchoscopy.

    We herein report a case of pulmonary renal syndrome with nephritis in a 17-year-old boy with diffuse alveolar hemorrhage (DAH) associated with acute poststreptococcal glomerulonephritis (APSGN). The patient exhibited hemoptysis two weeks after developing impetigo, and DAH was diagnosed on bronchoscopy. Respiratory failure progressed, and high-dose methylprednisolone therapy was administered; the respiratory failure regressed immediately after the onset of therapy. Streptococcus pyogenes was detected in an impetigo culture, and, together with the results of the renal biopsy, a diagnosis of APSGN was made. This case demonstrates the effects of high-dose methylprednisolone therapy in improving respiratory failure.

    Full Text Available Congenital pulmonary agenesis or aplasia is extremely rare. Although more than fifty percent of patients die before first five years of age, some individuals may remain asymptomatic throughout their life. A three-month-old female child with right pulmonary agenesis presented to us with severe respiratory distress. She was misdiagnosed as a case of foreign body bronchus at the peripheral health centre. Bronchoscopy confirmed the diagnosis and relieved the symptoms. It is recommended that invasive diagnostic procedures and prophylactic surgery should not be done in asymptomatic cases.

    Multiple tracheal diverticulosis is a rare clinical entity. Tracheal diverticula are usually recognized radiologically as solitary right paratracheal air collections on thoracic computed tomography examination. They are usually asymptomatic but can occasionally present with persistent symptoms. We herein report the case of a 50-year-old male patient who underwent extensive evaluation for persistent cough. Multiple posterior right paratracheal air collections were recognized on thoracic multidetector computed tomography examination, which was confirmed as multiple-acquired posterior upper tracheal diverticula on flexible bronchoscopy. The patient improved with conservative medical management.

    Foreign body aspirations in children are relatively uncommon occurrences, but they can be a serious events, causing respiratory distress, atelectasis, chronic pulmonary infections, or death. Safety pins are not commonly aspirated objects and account for less than 3% of all foreign bodies found in the tracheobronchial tree. Fewer than 2% of patients require thoracotomy, and most aspirated materials can be removed by bronchoscopy, with low morbidity and mortality. A discussion of airway foreign bodies follows the presentation of a case of an older child who aspirated a safety pin, which required open thoracostomy for removal.

    Plastic bronchitis (PB), although a rare cause of airway obstruction, has mortality rates up to 50% in children after Fontan-type cardiac surgery. We present the case of an 18-month-old female patient with PB following pneumonia. At 6 months of age, the patient underwent the Glenn procedure due to functionally univentricular heart. Fiberoptic bronchoscopy revealed complete blockage of the left bronchus by mucoid casts. Pharmacotherapy consisted of glucocorticosteroids, azithromycin, and enalapril maleate. The child also received nebulized 3% NaCl solution, which proved to be beneficial. In children submitted to Fontan-type procedures, physicians must be alert for PB, which can be triggered by respiratory tract infection.

    So, Tsz-Yin; Farrington, Elizabeth

    2008-01-01

    Topical benzocaine is an anesthetic agent that is often used before procedures and clinical tests, such as esophagoscopy, bronchoscopy, and endotracheal intubation. However, a potential deadly condition known as methemoglobinemia can occur with this agent. It causes the oxidation of hemoglobin to methemoglobinemia to occur more rapidly than the reduction of methemoglobin back to hemoglobin. Certain congenital and clinical conditions that affect oxygen delivery can increase the patient's risk of having methemoglobinemia develop with the use of benzocaine. Topical benzocaine-induced methemoglobinemia can occur in the pediatric population. Prompt management with intravenous methylene blue should be initiated for reversal.

    Endobronchial tuberculosis is defined as a tuberculous infection of the tracheobronchial tree and has a prevalence of up to 50% in active pulmonary tuberculosis cases. The most common complication of endobronchial tuberculosis is bronchial stenosis; benign fistula formation by endobronchial tuberculosis is rare, especially inter-bronchial fistula formation. We reported a rare case of a 73-year-old woman with a fistula between the right upper bronchus and bronchus intermedius. A diagnosis of inter-bronchial fistula caused by endobronchial tuberculosis was based on the results of chest computed tomography scans, bronchoscopy, and microbiological and pathological tests. The patient was treated with anti-tuberculous medication, and her symptoms gradually improved.

    The aim of this pictorial essay was to present the main computed tomography findings seen in diffuse diseases of the trachea. The diseases studied included amyloidosis, tracheobronchopathia osteochondroplastica, tracheobronchomegaly, laryngotracheobronchial papillomatosis, lymphoma, neurofibromatosis, relapsing polychondritis, Wegener's granulomatosis, tuberculosis, paracoccidioidomycosis, and tracheobronchomalacia. The most common computed tomography finding was thickening of the walls of the trachea, with or without nodules, parietal calcifications, or involvement of the posterior wall. Although computed tomography allows the detection and characterization of diseases of the central airways, and the correlation with clinical data reduces the diagnostic possibilities, bronchoscopy with biopsy remains the most useful procedure for the diagnosis of diffuse lesions of the trachea.

    Full Text Available We present a 54 year old male patient who had a bilateral lung transplant sixteen years ago for Alpha-1 Antitrypsin Deficiency-related emphysema. He was referred for flexible bronchoscopy with transbronchial biopsies to evaluate new mild exertional dyspnea and worsening of his FEV1. Eight transbronchial biopsies were done from the right middle lobe and the right lower lobe. Post procedure he developed bilateral pneumothoces that required emergent bilateral pleural ‘pigtail’ catheters. To our knowledge, this is the first reported case of bilateral pneumothoraces that developed after a unilateral procedure in a bilateral lung transplant recipient relatively late after the transplant.

    Full Text Available Abstract Background Cough is the most common symptom presenting to doctors. The quality of cough (productive or wet vs dry is used clinically as well as in epidemiology and clinical research. There is however no data on the validity of cough quality descriptors. The study aims were to compare (1 cough quality (wet/dry and brassy/non-brassy to bronchoscopic findings of secretions and tracheomalacia respectively and, (2 parent's vs clinician's evaluation of the cough quality (wet/dry. Methods Cough quality of children (without a known underlying respiratory disease undergoing elective bronchoscopy was independently evaluated by clinicians and parents. A 'blinded' clinician scored the secretions seen at bronchoscopy on pre-determined criteria and graded (1 to 6. Kappa (K statistics was used for agreement, and inter-rater and intra-rater agreement examined on digitally recorded cough. A receiver operating characteristic (ROC curve was used to determine if cough quality related to amount of airway secretions present at bronchoscopy. Results Median age of the 106 children (62 boys, 44 girls enrolled was 2.6 years (IQR 5.7. Parent's assessment of cough quality (wet/dry agreed with clinicians' (K = 0.75, 95%CI 0.58–0.93. When compared to bronchoscopy (bronchoscopic secretion grade 4, clinicians' cough assessment had the highest sensitivity (0.75 and specificity (0.79 and were marginally better than parent(s. The area under the ROC curve was 0.85 (95%CI 0.77–0.92. Intra-observer (K = 1.0 and inter-clinician agreement for wet/dry cough (K = 0.88, 95%CI 0.82–0.94 was very good.

Patients and methods: The clinical data of 17 geriatric patients with foreign-body aspiration were retrospectively analyzed and compared with 26 nongeriatric adult patients. The data were collected from Peking University First Hospital and Anhui Chest Hospital between January 2000 and June 2014.Results: (1 In the geriatric group, the most common symptoms were cough and sputum (15 cases, 88%, dyspnea (six cases, 35%, and hemoptysis (four cases, 24%. Five patients (29% in the geriatric group could supply the history of aspiration on their first visit to doctor, a smaller percentage than in the nongeriatric group (13 cases, 50%. Only three cases in the geriatric group were diagnosed definitely without delay. Another 14 cases were misdiagnosed as pneumonia or lung cancer, and the time of delayed diagnosis ranged from 1 month to 3 years. Complications due to delay in diagnosis included obstructive pneumonitis, atelectasis, lung abscess, and pleural effusion. (2 Chest computed tomography demonstrated the foreign body in three cases (21% in the geriatric group, which was lower than the positive proportion of detection in the nongeriatric group (nine cases, 35%. The most common type of foreign body in the geriatric group was food, such as bone fragments (seven cases, 41% and plants (seven cases, 41%, and the foreign body was most often lodged in the right bronchus tree (eleven cases, 65%, especially the right lower bronchus (seven cases, 41%.

    Full Text Available Patients with chronic obstructive pulmonary disease (COPD are susceptible to airway malacia, which may be unmasked following mechanical ventilation or tracheostomy decannulation. Dynamic imaging of central airways, a non-invasive test as effective as bronchoscopy to diagnose airway malacia, has increased the recognition of this disorder. We describe a 70-year-old woman admitted with adult respiratory distress syndrome. She had cardiorespiratory arrest on admission, from which she was successfully resuscitated. She had obesity, hypertension, diabetes mellitus, recurrent ventricular tachycardia, sarcoidosis with interstitial lung disease and COPD. She received short-term (18 days mechanical ventilation with tracheostomy and developed respiratory distress following tracheostomy decannulation.

    Wegeners granulomatosis is an inflammatory systemic necrotizing idiopathic vasculitis affecting mainly small vessels. In this paper we analyzed the computed tomography findings of seven patients with Wegeners granulomatosis. The most common findings were masses and nodules (71.4%), areas of ground glass attenuation (57.1%), consolidation (42.8%), halo sign (42.8%), cavitation (42.8%), interlobular septa thickening (14.2%), bronchial wall thickening (14.2%) and pleural effusion (14.2%). Although radiological findings are mostly nonspecific, computed tomography and particularly high-resolution computed tomography are important tools in the evaluation of disease activity when evaluated in association with bronchoscopy findings and clinical data.

    2016-02-15

    Tracheal wall disruption is a rare complication of endotracheal intubation, typically occurring in the posterior (membranous) trachea lacking cartilaginous support. We present the case of a 68-year-old man who developed an anterior tracheal tear after routine endotracheal intubation, most likely occurring secondary to protrusion of a factory-preloaded stylet beyond the distal orifice of the endotracheal tube. Tracheal disruption should be considered in any patient with subcutaneous emphysema and respiratory distress after tracheal extubation and confirmed with bronchoscopy. Conservative management may be appropriate for those with small tears, hemodynamic stability, and the ability to isolate the tear from positive pressure ventilation.

    Full Text Available We describe a patient with long-standing ankylosing spondylitis who underwent percutaneous nephrolithotomy under spinal anesthesia. At preoperative assessment, it was considered that intubation of the trachea was likely to be difficult. Fiberoptic bronchoscopy was attempted, but without success. As the standard technique for spinal anesthesia failed, a variation of the paramedian approach in the lumbosacral approach, also known as Taylor′s approach was successfully attempted. This resulted in adequate sensory and motor blockade for the surgical procedure. The patient did not require airway interventions, but equipment and aids to secure airway were available.

    In the article, a new method of diagnosing the extent of the tumor spread in the bronchial wall without involvement of the mucosa (a peripbronchial form of the growth) is described. The method consists of two components - angiography of bronchial arteries with subsequent injection of a staining material in the corresponding bronchial artery and bronchoscopy, by means of which staining of the mucous membrane of the bronchial tree is observed. In case of tumor infiltration of the bronchial wall staining was absent completely or partially. A clinical trial of the method indicated its high efficacy.

    Purpose: Various bronchoscopic navigation systems are developed for diagnosis, staging, and treatment of lung and bronchus cancers. To construct electromagnetically navigated bronchoscopy systems, registration of preoperative images and an electromagnetic tracker must be performed. This paper proposes a new marker-free registration method, which uses the centerlines of the bronchial tree and the center of a bronchoscope tip where an electromagnetic sensor is attached, to align preoperative images and electromagnetic tracker systems. Methods: The chest computed tomography (CT) volume (preoperative images) was segmented to extract the bronchial centerlines. An electromagnetic sensor was fixed at the bronchoscope tip surface. A model was designed and printed using a 3D printer to calibrate the relationship between the fixed sensor and the bronchoscope tip center. For each sensor measurement that includes sensor position and orientation information, its corresponding bronchoscope tip center position was calculated. By minimizing the distance between each bronchoscope tip center position and the bronchial centerlines, the spatial alignment of the electromagnetic tracker system and the CT volume was determined. After obtaining the spatial alignment, an electromagnetic navigation bronchoscopy system was established to real-timely track or locate a bronchoscope inside the bronchial tree during bronchoscopic examinations. Results: The electromagnetic navigation bronchoscopy system was validated on a dynamic bronchial phantom that can simulate respiratory motion with a breath rate range of 0–10 min{sup −1}. The fiducial and target registration errors of this navigation system were evaluated. The average fiducial registration error was reduced from 8.7 to 6.6 mm. The average target registration error, which indicates all tracked or navigated bronchoscope position accuracy, was much reduced from 6.8 to 4.5 mm compared to previous registration methods.

    Full Text Available Bronchial webs are thin, membrane-like diaphragms that may obstruct the airway. Several congenital cases have been reported. Though rare, the true incidence of these lesions is probably underestimated because many of them are unrecognized. The case of a 71-year-old woman with an acquired bronchial web causing right main stem bronchus obstruction that went unrecognized for 47 years post-trauma is reported. The lesion was successfully treated using rigid bronchoscopy with laser therapy, balloon dilation and stent placement. This is the first reported case of an acquired bronchial web formation. It is also the first reported case that was successfully treated with this technique.

Two thoracenteses failed to reveal any cytologic abnormalities. Bronchoscopy revealed smooth, round, endobronchial lesions. Histologic examination showed features consistent with leiomyosarcoma. We present a rare case of a patient that initially had possible leiomyomas of the uterus surgically removed and years later presented with bronchopulmonary leiomyosarcoma.

A 73 year-old woman, a lifetime non-smoker, presented to the pulmonary clinic with chronic dyspnea on exertion and cough. Physical exam was unremarkable and pulmonary function testing showed normal spirometry. A chest radiograph revealed calcified mediastinal adenopathy and increased density in the right middle lobe region (Figure 1. A computed tomography scan of the chest revealed significant narrowing of the right middle lobe bronchus with partial atelectasis and prominent calcified mediastinal lymphadenopathy (Figure 2. Bronchoscopy showed no endobronchial lesions but there was evidence of extrinsic compression surrounding the right middle lobe orifice. An endobronchial biopsy revealed noncaseating granulomas. Bronchoscopy cultures and cytology were negative and this was presumed to be from a previous infection with histoplasmosis given the patient’s long-term residence in an endemic area. Given chronic narrowing of right middle lobe bronchus with persistent atelectasis of the right middle lobe, the patient was diagnosed with right middle lobe syndrome. ...

    Lung cancer configures as one of the deadliest types of cancer. The future implementation of early screening methods such as exhaled breath condensate analysis and low dose computed tomography (CT) as an alternative to current chest imaging based screening will lead to an increased burden on bronchoscopy units. New approaches for improvement of diagnosis in bronchoscopy units, regarding patient management, are likely to have clinical impact in the future. Diagnostic approaches to address mortality of lung cancer include improved early detection and stratification of the cancers according to its prognosis and further response to drug treatment. In this study, we performed a detailed mass spectrometry based proteome analysis of acellular bronchoalveolar lavage (BAL) fluid samples on an observational prospective cohort consisting of 90 suspected lung cancer cases which were followed during two years. The thirteen new lung cancer cases diagnosed during the follow up time period clustered, based on liquid chromatography-mass spectrometry (LC-MS) data, with lung cancer cases at the time of BAL collection. Hundred and thirty-tree potential biomarkers were identified showing significantly differential expression when comparing lung cancer versus non-lung cancer. The regulated biomarkers showed a large overlap with biomarkers detected in tissue samples. PMID:28169345

    Full Text Available Foreign body aspiration (FBA is common under 3 years of age. FBA can cause sudden respiratory failure. Furthermore, it leads to many respiratory system complications. Therefore, FBA is an important cause of mortality and morbidity for this age group. FBA cases are usually followed by diagnoses like pneumonia, bronchitis or bronchial asthma in the late period that history, clinical and laboratory findings suggesting foreign body aspiration can not be detected. We reported a 2-year-old male patient with pneumonia, who were administered various treatments. In thorax CT of this case, an image compatible with foreign body was seen in the right middle lobe-upper lobe separation area. Granulation tissue was detected in the entrance of the right main bronchus by rigid bronchoscopy and marked improvement occured in lung aeration after bronchoscopy. This case was reported to emphasize the importance of early diagnosis of foreign body aspiration because of high mortality and morbidity and the necessity of considering the foreign body aspiration in children with recurrent pulmonary infections.

    Endobronchial ultrasound bronchoscopy has been one of the most important contributions to the minimally invasive diagnosis and staging of mediastinal disease in the last few years. Two original works with linear and radial endobronchial ultrasound bronchoscopy published in the Archivos de Bronconeumología are analysed. In pleural pathology, we have selected a multicentre study one the usefulness of an outpatient tunnelised pleural drainage in 63 patients with malignant neoplastic effusions. This technique was indicated in 20% when pleurodesis failed or was not indicated, and an overall symptomatic improvement was achieved in 95% of cases. In interstitial diseases, we highlight the article on the usefulness of BAL in the initial diagnosis of these diseases in a series of 562 patients studied over 14 years. The authors highlight the minimal invasiveness of the technique and its value which, when added to the radiological and clinical findings, enables these diseases to be managed without surgical biopsy in around 90% of cases. Finally, we highlight the works on lung transplant which analysed the value of interleukin-8 by BAL in the donor lung to detect sub-clinical involvement that could lead to a primary dysfunction of the lung graft, the risk factors associated to mortality in 92 lung transplant receivers due to emphysema and, lastly, the experience of the transplant in 15 patients with pulmonary arterial hypertension in an advanced functional class, with a peri-operative survival at 5 years of 40%.

    A review has been made of original articles on invasive pneumology techniques, interstitial diseases and lung transplantation, published in the Archivos de Bronconeumología during the year 2008. We have selected the publication by Martínez-Olondrins et al on the mediastinal staging of bronchogenic carcinoma by transbronchial needle aspiration to highlight the role of this simple, safe and cost-effective technique at a time when aspiration by ultrasound-guided bronchoscopy is profiled as an alternative to staging by mediastinoscopy. Besides its usefulness in the study of lymph nodes, transbronchial needle aspiration increases the overall performance of bronchoscopy by 20%, which means that it should be considered as a basic tool in the study of lung cancer. We also comment on the work by Galvis-Caravajal et al, who describe percutaneous radiofrequency as an alternative to radiotherapy in small lung or metastasic tumours. In diffuse interstitial disease, Morell et al analysed the diagnostic methods in 500 patients with this clinical-radiological presentation in which a definitive diagnosis was achieved in 85%, with 25% of them being obtained by non-invasively. Baloira et al analysed the characteristics of 19 patients with desquamative interstitial pneumonia and respiratory bronchiolitis associated-interstitial lung disease obtained from the National register of Interstitial Diseases.

    Objective: In order to achieve immediate relief of central airway obstruction caused by malignant tumor after interventional therapy, we observed the efficacy and safety of cryorecanalization after cryosurgery via flexible bronchoscope. Methods: A total of 64 cases of patients in all suffered from central airway obstruction were observed and treated by applying cryorecanalization after cryosurgery via flexible bronchoscope. Divide the operation into two steps, including cryosurgery and cryorecanalization. Evaluate the therapeutic effect immediately after the treatment, wherein the evaluating indicator includes preoperative and postoperative dyspnea indexes, quality of life score, bronchoscopy, etc. The surgical safety assessment is mainly by observing the risk of bleeding in the surgery. Results: Forty cases (62.5%) has postoperative dyspnea score improved at least one level compared with preoperative dyspnea score, 24 patients (37.5%) have no significant improvement on dyspnea score. Quality of life score (Karnofsky score): preoperative 52 ± 18.7 points, postoperative 70 ± 9.2 points. Bronchoscopy review: complete success in 12 cases (18.8%), partial success in 45 cases (70.3%), no success in 7 cases (12%).89.1% overall clinical efficiency was achieved. In the surgery, the control to bleeding was satisfactory since no severe bleeding, moderate bleeding in 14 cases (21.9%) and mild bleeding in 50 cases (78.1%) were found as well as rigid bronchoscope was free. Conclusion: The central airway obstruction can be immediately relieved by cryorecanalization after cryosurgery via flexible bronchoscope with satisfactory effects and higher surgical safety.

    The ideal airway management modality in pediatric patients with syndromes like Klippel-Feil syndrome is a great challenge and is technically difficult for an anesthesiologist. Half of the patients present with the classic triad of short neck, low hairline, and fusion of cervical vertebra. Numerous associated anomalies like scoliosis or kyphosis, cleft palate, respiratory problems, deafness, genitourinary abnormalities, Sprengel's deformity (wherein the scapulae ride high on the back), synkinesia, cervical ribs, and congenital heart diseases may further add to the difficulty. Fiberoptic bronchoscopy alone can be technically difficult and patient cooperation also becomes very important, which is difficult in pediatric patients. Fiberoptic bronchoscopy with the aid of supraglottic airway devices is a viable alternative in the management of difficult airway in children. We report a case of Klippel-Feil syndrome in an 18-month-old girl posted for cleft palate surgery. Imaging of spine revealed complete fusion of the cervical vertebrae with hypoplastic C3 and C6 vertebrae and thoracic kyphosis. We successfully managed airway in this patient by fiberoptic intubation through classic laryngeal mask airway (LMA). After intubation, we used second smaller endotracheal tube (ETT) to stabilize and elongate the first ETT while removing the LMA. PMID:25191201

    Integrated positron emission tomography (PET) / computed-tomography (CT) scanners give 3D multimodal data sets of the chest. Such data sets offer the potential for more complete and specific identification of suspect lesions and lymph nodes for lung-cancer assessment. This in turn enables better planning of staging bronchoscopies. The richness of the data, however, makes the visualization and planning process difficult. We present an integrated multimodal 3D PET/CT system that enables efficient region identification and bronchoscopic procedure planning. The system first invokes a series of automated 3D image-processing methods that construct a 3D chest model. Next, the user interacts with a set of interactive multimodal graphical tools that facilitate procedure planning for specific regions of interest (ROIs): 1) an interactive region candidate list that enables efficient ROI viewing in all tools; 2) a virtual PET-CT bronchoscopy rendering with SUV quantitative visualization to give a "fly through" endoluminal view of prospective ROIs; 3) transverse, sagittal, coronal multi-planar reformatted (MPR) views of the raw CT, PET, and fused CT-PET data; and 4) interactive multimodal volume/surface rendering to give a 3D perspective of the anatomy and candidate ROIs. In addition the ROI selection process is driven by a semi-automatic multimodal method for region identification. In this way, the system provides both global and local information to facilitate more specific ROI identification and procedure planning. We present results to illustrate the system's function and performance.

    One-lung ventilation (OLV) is a sine qua non of thoracic surgery and requires knowledge and talent. Close familiarity with equipments used for OLV as well as bronchoscopy and respiratory tract anatomy is important for successful OLV. We aim to outline the bronchoscopic anatomy of the tracheobronchial tree and OLV equipment for anesthetists and thoracic surgeons in this review. The recorded preoperative and intraoperative bronchoscopic applications of the patients hospitalized in our Thoracic Surgery clinic for diagnosis and treatment have been evaluated from an anesthetist's perspective. Anatomic landmarks were identified in the bronchoscopic evaluation. Optimal and misplacement images of double-lumen tubes (DLT) and bronchial blockers (BB) used for OLV in our clinic were obtained via fiber optic bronchoscopy. While left lung isolation can be made more safely due to the anatomy of the left main bronchus, placement of both DLTs and BBs to the right main bronchus requires greater care. Success in OLV procedures would increase with anesthetists being well informed about the fiber optic bronchoscopic anatomy of the tracheobronchial tree and in close cooperation with the surgical team.

    The present study was performed to improve early lung cancer diagnosis in bronchial washing fluid, thereby increasing the diagnostic sensitivity of bronchoscopy by means of high-resolution flow cytometry (FC). We combined dual-parameter DNA/protein FC and conventional cytology in bronchial washing fluid samples from 112 patients with neoplastic and non-neoplastic lung diseases and found 43% of histologically confirmed tumor cases to be cytologically positive; 63% of the tumor samples were aneuploid, 52% of the aneuploid cases were cytologically positive and 48% were negative. In the negative cases, FC was an independent diagnostic factor. In 32% of the cases, FC also failed to detect abnormalities. However, the combination of both techniques increased the sensitivity in detecting neoplastic cells to 73%. Furthermore, simultaneous DNA/protein analysis allowed the recognition of aneuploid cell lines not detectable by single DNA measurement. Identification of aneuploid subpopulations by dual-parameter analysis in cytologically negative one-parameter FC "diploid" samples assumes an important diagnostic value. Dual-parameter DNA/protein FC is a valuable technique that increases the diagnostic yield of bronchoscopy with no risk for the patient and a low additional cost.

    On January 2013, a disaster at Santa Maria (RS) due to a fire in a confined space caused 242 deaths, most of them by inhalation injury. On November 2013, four individuals required intensive care following smoke inhalation from a fire at the Memorial da América Latina in São Paulo (SP). The present article reports the clinical progression and management of disaster victims presenting with inhalation injury. Patients ERL and OC exhibited early respiratory failure, bronchial aspiration of carbonaceous material, and carbon monoxide poisoning. Ventilation support was performed with 100% oxygen, the aspirated material was removed by bronchoscopy, and cyanide poisoning was empirically treated with sodium nitrite and sodium thiosulfate. Patient RP initially exhibited cough and retrosternal burning and subsequently progressed to respiratory failure due to upper airway swelling and early-onset pulmonary infection, which were treated with protective ventilation and antimicrobial agents. This patient was extubated following improvement of edema on bronchoscopy. Patient MA, an asthmatic, exhibited carbon monoxide poisoning and bronchospasm and was treated with normobaric hyperoxia,bronchodilators, and corticosteroids. The length of stay in the intensive care unit varied from four to 10 days, and all four patients exhibited satisfactory functional recovery. To conclude, inhalation injury has a preponderant role in fires in confined spaces. Invasive ventilation should not be delayed in cases with significant airway swelling. Hyperoxia should be induced early asa therapeutic means against carbon monoxide poisoning, in addition to empiric pharmacological treatment in suspected cases of cyanide poisoning.

    The present study assessed the diagnostic usefulness of a multiplex PCR (mPCR) for Streptococcus pneumoniae, Haemophilus influenzae, Mycoplasma pneumoniae and Chlamydophila pneumoniae applied to bronchoalveolar lavage (BAL). Fibreoptic bronchoscopy was performed on 156 hospitalised adult patients with lower respiratory tract infection (LRTI) and 36 controls. BAL fluid was analysed with bacterial culture and mPCR. By conventional diagnostic methods, S. pneumoniae, H. influenzae, M. pneumoniae and C. pneumoniae were aetiological agents in 14, 21, 3.2 and 0% of the LRTI patients, respectively. These pathogens were identified by BAL mPCR in 28, 47, 3.2 and 0.6% of cases, respectively, yielding sensitivities of 86% for S. pneumoniae, 88% for H. influenzae, 100% for M. pneumoniae and 0% for C. pneumoniae, and specificities of 81, 64, 100 and 99% for S. pneumoniae, H. influenzae, M. pneumoniae and C. pneumoniae, respectively. Of the 103 patients who had taken antibiotics prior to bronchoscopy, S. pneumoniae was identified by culture in 2.9% and by mPCR in 31%. Among the controls, mPCR identified S. pneumoniae in 11% and H. influenzae in 39%. In lower respiratory tract infection patients, bronchoalveolar lavage multiplex PCR can be useful for identification of Streptococcus pneumoniae, Mycoplasma pneumoniae and Chlamydophila pneumoniae. The method appears to be particularly useful in patients treated with antibiotics.

    Plastic bronchitis or cast bronchitis is a rare disease of unclear etiology characterized by formation of airway casts that can lead to life-threatening airway obstruction. There is currently limited data regarding optimal treatment of plastic bronchitis. Several therapies have been suggested, but recurrences are common and mortality remains high. We report the case of a 6-year-old boy with refractory eosinophilic bronchial casts, unresponsive to low-dose systemic corticosteroids, inhaled corticosteroids, azithromycin, and dornase alfa, who was treated successfully and safely with direct instillation of tissue-type plasminogen activator (tPA) to the obstructing casts during flexible bronchoscopy and inhaled tPA. Our case illustrates that the current therapy for plastic bronchitis remains inadequate. To our knowledge, this case is the first to show that direct instillation of tPA can be used safely for treatment of this disease. The use of tPA via direct administration into the airways during bronchoscopy and via a nebulizer appeared to be a safe and effective therapy for plastic bronchitis and should be considered early in the course of the disease to prevent complications of severe airway obstruction.

    Endobronchial ultrasound (EBUS) is now commonly used for cancer-staging bronchoscopy. Unfortunately, EBUS is challenging to use and interpreting EBUS video sequences is difficult. Other ultrasound imaging domains, hampered by related difficulties, have benefited from computer-based image-segmentation methods. Yet, so far, no such methods have been proposed for EBUS. We propose image-segmentation methods for 2-D EBUS frames and 3-D EBUS sequences. Our 2-D method adapts the fast-marching level-set process, anisotropic diffusion, and region growing to the problem of segmenting 2-D EBUS frames. Our 3-D method builds upon the 2-D method while also incorporating the geodesic level-set process for segmenting EBUS sequences. Tests with lung-cancer patient data showed that the methods ran fully automatically for nearly 80% of test cases. For the remaining cases, the only user-interaction required was the selection of a seed point. When compared to ground-truth segmentations, the 2-D method achieved an overall Dice index = 90.0% ±4.9%, while the 3-D method achieved an overall Dice index = 83.9 ± 6.0%. In addition, the computation time (2-D, 0.070 s/frame; 3-D, 0.088 s/frame) was two orders of magnitude faster than interactive contour definition. Finally, we demonstrate the potential of the methods for EBUS localization in a multimodal image-guided bronchoscopy system.

    The use of the Sanders venturi system during bronchoscopy in adults has been studied extensively. Its use in paediatric bronchoscopy has been limited because small changes in the characteristics of the system may produce large changes in the patient. With jet ventilation, peak inflation pressures and flow rates are influenced by the driving pressure, diameter and shape of the bronchoscope, the diameter of the injector and its length and angle from the axial line of the bronchoscope. Storz 3 mm, 4 mm and 5 mm rigid fibreoptic bronchoscopes were evaluated in a test lung with an injector of 1.5 mm internal diameter fixed in the side-arm at 20 degrees to the axial line. Pilling 3 mm, 4 mm and 5 mm rigid fibreoptic bronchoscopes were also examined using the standard injector with a 0.89 mm orifice in the axial line. The Storz bronchoscopes produced consistently higher peak inflation pressures and flow rates at all driving pressures in spite of the relatively large angle of the injector from the axial line. Caution is advised in the use of the Storz injector system as excessively high inflation pressures may be reached.

Extrapulmonary causes of lung abscess were consist of: 10 case (10% aspiration, 10 case (19% esophageal diseases tending to reflux, 5 case (9% periodontal disease. The factors, which had underiable effects on prognosis of disease were lung cancer, anemia, hypoalbuminemia, age over 60, abscess with pseudomonas, abscess cavity greater thus 8 cm, lower lobe in right lung and TB. Because of high mortality and morbidity of lung abscess, due attention for internal drainage, bronchoscopy, physiotherapy and timed surgery are seriously indicated.

    Vallecular cysts are an unusual cause of congenital stridor. To describe the imaging findings in five patients, with emphasis on the usefulness of sonographic studies. Between 1990 and 2007, five patients with a cystic lesion situated in the anterior neck, at the vallecular space, were seen in our institution. Clinical records and imaging findings were retrospectively reviewed. All patients presented with persistent inspiratory stridor that was present from the first week of life. Neck US was performed as part of the investigations in four and showed a vallecular cyst. The diagnosis was confirmed with flexible bronchoscopy in four infants and CT in one; all were resected. Pathology showed a multilayered epithelial border with normal thickness and differentiation; there were no signs of malignancy. Although vallecular cysts are very rare, they should be considered in the differential diagnosis of congenital stridor. When the commonest causes have been ruled out, neck US may be diagnostic. The diagnosis can be confirmed with flexible bronchoscopy or further imaging such as CT or MRI. (orig.)

    A portable oxygen system in combination with transtracheal O2 delivery (SCOOP(R)) permits patients with respiratory failure optimal mobility and facilitates longterm oxygen therapy. This report describes a 70 year old female with COPD that developed acute respiratory distress 18 days after inserting PRESCOOP(R) and 11 days after changing to SCOOP 1 catheter. Catheter stripping had not revealed any pathology. Flexible bronchoscopy showed a mucus ball at the catheter tip leading to a 80% stenosis of the trachea. Trials to remove the ball with forceps and a loop were not successful until a rigid bronchoscop was inserted. Up to 10% of patients develop mucus ball formation with SCOOP 1 catheter which remains in situ for 6 weeks. In patients with high risk of mucus formation (high O2 flow, viscous mucus, low FEV1) the manufacturers of SCOOP recommend catheter stripping. We consider a control bronchoscopy being safer 1 week after changing from PRESCOOP to SCOOP because one patient has been reported to have died of this complication and our patient has developed a near fatal situation.

    Full Text Available Literature has described many causes of failed decannulation and weaning. However, failed decannulation and weaning from ventilator due to a hilar lymph node compressing upon a bronchus has not been described. We report a case of a 30-year-old man with Guillain-Barré syndrome who had quadriparesis and respiratory distress. After 1 year of intensive care unit admission, he was ambulatory, haemodynamically stable, devoid of sepsis, had effective cough with tracheostomy in situ. Every attempt of decannulation led to pooling of secretions in left side of chest, hypercarbia and altered sensorium. This was followed by re-institution of ventilator support. Chest x-ray was unremarkable, but computed tomography (CT chest done during this time showed a mass compressing upon left lower lobe bronchus. Flexible fibre-optic bronchoscopy and transbronchial biopsy confirmed the diagnosis to be tubercular lymph node. After 1 month of starting of anti-tubercular treatment, there was resolution of the mass with relief of the bronchial compression and a successful decannulation thereafter. Role of CT in difficult cases of weaning is emphasized, and role of bronchoscopy is highlighted in difficult cases of weaning and decannulation.

    The aim of the study was to evaluate the efficacy of cough-preventing treatment with levodropropizine, a drug inhibiting peripheral cough reflexes, in patients undergoing bronchial endoscopy. Sixteen patients, aged 37-73 years, suffering from chronic obstructive lung disease in the hypersecretory phase, were included in the study. The experiment was designed as double blind with double observer, controlled versus placebo. As comparative efficacy parameters were considered the number of anaesthetic boluses (lidocaine at 2%) administered during and immediately after the manoeuvre. The number of coughs during and 10 min after bronchoscopy was registered on a magnetic tape and read by a blinded observer thereafter. Levodropropizine was given as oral drops (20 each time, equal to 60 mg active drug) 12 h and 1 h before bronchoscopy. Data analysis was performed by descriptive statistical tests and by the non-parametric Wilcoxon test for paired samples. Levodropropizine treatment significantly reduced the number of anaesthetic enemas (p less than 0.01), and presented an excellent tolerability and safety profile.

    Full Text Available A 19-year-old Vietnamese lady was diagnosed with culture positive, left upper lobe pulmonary tuberculosis for which medical treatment was initiated. Four months into treatment, she developed a 'rubber-band-like' stretching sensation in her left chest with wheezing and shortness of breath. Decreased respiratory excursion over the left lung was present on physical-examination. Chest-Xray revealed left-upper-lobe collapse with leftward deviation of the trachea and mediastinum. CT thorax revealed a long segment of stenosis in the left mainstem bronchus. FEV1 was 1.26 L (45% predicted, FVC 1.53 L (49% predicted, FEV1/FVC 82% (95% predicted indicating airway limitation. Ventilation-perfusion scan noted 9.8% ventilation to the left lung and 92.8% to the right lung and 7.6% perfusion to the left lung and 92.4% to the right lung. Bronchoscopy was notable for pin point stenosis of the left mainstem bronchus beyond which was inflamed mucosa and abnormal cartilage rings in the left upper and middle lobe bronchi. Nine months of medical therapy for tuberculosis along with oral steroid taper was completed successfully; however the patient has required six serial bronchscopies with dilatations without stent placement at four to six week intervals due to partial restenosis, with the last bronchoscopy at four months after completion of tuberculosis therapy.

    Combining a polymerase chain reaction (PCR) test with bronchoscopy is frequently performed to allow a rapid diagnosis of smear-negative pulmonary tuberculosis (PTB). However, limited data are available concerning clinical judgment in patients with suspected PTB and AFB smear- and PCR-negative bronchial aspirates (BA). The present study evaluated the usefulness of whole-blood QuantiFERON-TB Gold In-Tube (QFT) testing in these patients. Of 166 patients with suspected PTB who had undergone bronchoscopy because of smear-negative sputum or inadequate sputum production, 93 (56%) were diagnosed with culture-positive PTB. Seventy-four patients were either AFB smear- or PCR-positive. In the 75 patients whose BA AFB smear and PCR results were both negative, 19 were finally diagnosed with PTB by culture. The QFT test had a negative predictive value of 91% for PTB. The QFT test may be useful for excluding PTB in patients with suspected PTB whose BA AFB smear and PCR results are both negative.

  9. Method for endobronchial video parsing

    2016-03-01

    Endoscopic examination of the lungs during bronchoscopy produces a considerable amount of endobronchial video. A physician uses the video stream as a guide to navigate the airway tree for various purposes such as general airway examinations, collecting tissue samples, or administering disease treatment. Aside from its intraoperative utility, the recorded video provides high-resolution detail of the airway mucosal surfaces and a record of the endoscopic procedure. Unfortunately, due to a lack of robust automatic video-analysis methods to summarize this immense data source, it is essentially discarded after the procedure. To address this problem, we present a fully-automatic method for parsing endobronchial video for the purpose of summarization. Endoscopic- shot segmentation is first performed to parse the video sequence into structurally similar groups according to a geometric model. Bronchoscope-motion analysis then identifies motion sequences performed during bronchoscopy and extracts relevant information. Finally, representative key frames are selected based on the derived motion information to present a drastically reduced summary of the processed video. The potential of our method is demonstrated on four endobronchial video sequences from both phantom and human data. Preliminary tests show that, on average, our method reduces the number of frames required to represent an input video sequence by approximately 96% and consistently selects salient key frames appropriately distributed throughout the video sequence, enabling quick and accurate post-operative review of the endoscopic examination.

    To evaluate the value of dose-reduced 16-slice multidetector-row spiral computed tomography (16-MDCT) using virtual tracheobronchoscopy (VTB) and virtual bronchography (VBG) in children with suspected tracheobronchial stenosis. 12 children (4 d to 3 years, body weight 1.2 kg to 13.5 kg) with stridor and suspected tracheobronchial stenosis were examined by contrast-enhanced low-dose 16-MDCT. Conventional axial slices, MPRs, VTB, and VBG were calculated. Image findings were correlated with the results of fiberoptic bronchoscopy (12 out of 12) as a gold standard and subsequent surgery (8 out of 12). VTB and VBG demonstrated the fiberoptic bronchoscopically suspected tracheal stenosis in 11 of 12 children due to vascular compression because of the brachiocephalic trunk (6), a double aortic arch (2), a vascular compression of the left main bronchus (2), and a right aberrant subclavian artery (1). Eleven out of 12 stenoses were correctly depicted by conventional axial slices, MPRs, VTB, and VBG. Dose reduction was 79 to 85.8% compared to a standard adult chest CT. Dose-reduced 16-MDCT with the use of VTB and VBG is effective for the evaluation of tracheobronchial stenosis in children and correlates well with fiberoptic bronchoscopy. (orig.)

    Invasive aspergillus and mucormycosis infection are not uncommon in immunocompromised individuals. Endobronchial fungal infections have been reported in the literature, especially in patient's with diabetes complicated by diabetic ketoacidosis, but end bronchial coinfection with aspergillus and mucormycosis without pulmonary involvement has not been described in the literature. We report the case of a woman with diabetes who presented with gastrointestinal symptoms, ketoacidosis and respiratory distress, with an apparently normal chest X-ray. Investigations revealed a cavitatory lesion in the left lower lobe of the lungs on CT scan. Bronchoscopy revealed intense mucosal oedema and whitish plaques at the lower end of the trachea and right main stem bronchus with a normal left bronchial tree. Microbiological and pathological results confirmed aspergillus and mucormycosis. Despite aggressive medical management, the patient deteriorated and died of respiratory failure. Strong suspicion of invasive fungal infections in immunocompromised patients with respiratory failure and minimal chest infiltrates, early fibreoptic bronchoscopy and early aggressive treatment is crucial for the patient's survival.

    Combined use of local anesthetics and low-dose opioids enhances the effects of local anesthetics. This study aimed to evaluate the efficacy of combined administration of sufentanil and tetracaine through the cricothyroid membrane during awake nasal intubation using fiberoptic bronchoscopy in patients with difficult airways. Forty patients were divided into 2 groups: group A received endotracheal administration of 25 μg of sufentanil and 2 mL of 1% tetracaine mixture; group B received endotracheal administration of 2 mL 1% tetracaine and routine local anesthetic sprays followed by slow intravenous injection of 25 μg of sufentanil. The results showed that endotracheal intubation was safely completed in all patients and vital signs including blood pressure, heart rate, and pulse oxygen saturation were not significantly different between groups A and B. However, time required for local anesthesia to take effect, time required to complete intubation, cough reflex, patient tolerance during intubation, and hemodynamic indices were significantly better in group A than in group B. In conclusion, our results suggest that endotracheal administration of sufentanil combined with tetracaine is safe, effective, and feasible in the context of awake nasal intubation using fiberoptic bronchoscopy.

    Transbronchial biopsy using forceps (TBB) is the first diagnostic technique performed on patients with interstitial lung disease (ILD). However, the small size of the samples and the presence of artefacts in the tissue obtained make the yield variable. Our objectives were 1) to attempt to reproduce transbronchial cryobiopsy under the same conditions with which we performed conventional TBB, that is, in the bronchoscopy unit without intubating the patient and without fluoroscopy or general anaesthesia; 2) to describe the method used for its execution; and 3) to analyse the diagnostic yield and its complications. We carried out a prospective study that included 106 patients with clinical and radiological features suggestive of ILD who underwent cryo-transbronchial lung biopsy (cryo-TBB) under moderate sedation without endotracheal intubation, general anaesthesia or use of fluoroscopy. We performed the procedure using two flexible bronchoscopes connected to two video processors, which we alternated until obtaining the number of desired samples. A definitive diagnosis was obtained in 91 patients (86%). As for complications, there were five pneumothoraces (4.7%) and in no case was there severe haemorrhage or exacerbation of the underlying interstitial disease. Cryo-TBB following our method is a minimally invasive, rapid, safe and economic technique that can be performed in a bronchoscopy suite under moderate sedation without the need for intubating the patient or using fluoroscopy and without requiring general anaesthesia.

    Background: Multidetector CT-angiography (MDCTA) is commonly used in patients with severe haemoptysis requiring admission to intensive care unit. However, the impact of MDCTA on the management of severe haemoptysis in emergency setting is poorly evaluated. Methods: We prospectively compared data provided by clinical bedside evaluation (clinical examination, chest-X-ray and fiberoptic bronchoscopy) to MDCTA data in terms of lateralization, location of the bleeding site, etiology as well as impact on the treatment choice. Results: Over a 13-month period, 87 patients (men n = 58, median age = 61 years, median haemoptysis expectorated volume = 180 mL) were included. Etiology was mainly (67%) bronchiectasis, tuberculosis sequelae and tumor. MDCTA and clinical bedside evaluation were equally effective in determining lateralization (87.4% and 93.1%, respectively, p = 0.23) and location (85% and 82.7%, respectively, p = 0.82) of the bleeding site. MDCTA was significantly more accurate than the clinical bedside strategy in determining the haemoptysis cause (86% and 70%, respectively, p = 0.007). Moreover, MDCTA suggested the involvement of systemic arteries as bleeding mechanism in 92% of cases, leading to the modification of the treatment initially considered after bedside evaluation in 21.8% of patients. Conclusion: MDCTA provides useful information for the management of patients with severe haemoptysis, especially in the treatment choice. Thus, in the absence of emergency fiberoptic bronchoscopy (FOB) requirement for airways management, MDCTA should be the first-line procedure performed in emergency clinical setting.

    2015-10-01

    Full Text Available INTRODUCTI ON: Foreign body aspiration in pediatrics is a potentially fatal accident which will continue until children explore their surroundings with their hand and mouth. Pediatric aspirations will persist until mankind exists. Not all foreign body aspirations are witnessed hence chances of delay in diagnosing an aspiration are high. Delay in diagnosis depends on site and character of foreign body aspirated. The chest x - ray findings and type of foreign body extracted vary depending on the duration the foreign body remains in airway . OBJECTIVE: To study the X - ray finding in pediatric airway aspiration and its relation to time lapse, the type and site of lodgment of foreign body extracted via bronchoscopy. The type of foreign body in relation to time lapse in aspiration. MATERIAL AND METHODS: This was a prospective study done in Bapuji child health institute and research center, JJM Medical College, Davangere . History and pre bronchoscopy x - Ray finding were noted for 65 children who were posted for suspicious bronchoscopy from August 2011 to September 2013. 11 children were excluded from study as they showed no foreign body on bronchoscopy. Time lapse in aspir ation and seeking medical care was noted. The bronchoscopic findings regarding site of foreign body lodgment and type of foreign body were recorded. The type of foreign body and variation of x - ray picture in relation to time lapse in aspiration were noted. Data collected was analyzed using descriptive statistics. RESULT: It was observed that mean age was 28 months. About 80% of the cases were between 1 to 3 years age. 82% (n=53/54 were radio lucent foreign body, only 1.5% (n=1/54 were radio o paque. Site of lodgment of foreign body was right main bronchus in 48% (n=26/54, left main bronchus 46% (n=25/54 , tracheal 1.85% (n=1/54, subglottic 1.85% (n=1/54, carinal 1.85% (n=1/54, multiple site i.e. left bronchus +right bronchus+ carinal 1.85% (n=1/54.

    2011-07-01

    Background: Ambient air pollution is associated with adverse health effects, but the sources and components, which cause these effects is still incompletely understood. The aim of this thesis was to investigate the pulmonary effects of a variety of common air pollutants, including diesel exhaust, biomass smoke, and road tunnel and subway station environments. Healthy non-smoking volunteers were exposed in random order to the specific air pollutants and air/control, during intermittent exercise, followed by bronchoscopy. Methods and results: In study I, exposures were performed with diesel exhaust (DE) generated at transient engine load and air for 1 hour with bronchoscopy at 6 hours post-exposure. Immunohistochemical analyses of bronchial mucosal biopsies showed that DE exposure significantly increased the endothelial adhesion molecule expression of p-selectin and VCAM-1, together with increased bronchoalveolar lavage (BAL) eosinophils. In study II, the subjects were exposed for 1 hour to DE generated during idling with bronchoscopy at 6 hours. The bronchial mucosal biopsies showed significant increases in neutrophils, mast cells and lymphocytes together with bronchial wash neutrophils. Additionally, DE exposure significantly increased the nuclear translocation of the aryl hydrocarbon receptor (AhR) and phosphorylated c-jun in the bronchial epithelium. In contrast, the phase II enzyme NAD(P)H-quinone oxidoreductase 1 (NQO1) decreased after DE. In study III, the 2-hour exposures took place in a road tunnel with bronchoscopy 14 hours later. The road tunnel exposure significantly increased the total numbers of lymphocytes and alveolar macrophages in BAL, whereas NK cell and CD56+/T cell numbers significantly decreased. Additionally, the nuclear expression of phosphorylated c-jun in the bronchial epithelium was significantly increased after road tunnel exposure. In study IV, the subjects were exposed to metal-rich particulate aerosol for 2 hours at a subway station

    L'inhalation d’épingle à foulard (EF) est un phénomène de plus en plus fréquent dans les pays où les femmes portent le voile et dont les conséquences peuvent être graves. Le but de ce travail est de présenter notre expérience dans le diagnostic et la prise en charge de cette nouvelle entité clinique, de définir ses particularités et d'illustrer les dangers de la tenue d'une épingle à foulard dans la bouche. Soixante-dix cas d'inhalation d'EF ont été colligés en 8 ans (2007-2015). Il s'agit de 69 patientes, toutes voilées avec un âge moyen de 16,5 ans et d'un patient de 14 ans. Les patientes mettaient l’épingle entre leurs lèvres tout en fixant leurs foulards. L'inhalation a été accidentelle dans tous les cas. Le signe le plus fréquemment rapporté après inhalation était la toux. Le siège de l’épingle était plus fréquent au niveau de l'arbre bronchique gauche (52,9%). Une expulsion spontanée de l'EF a été notée dans 9 cas. La bronchoscopie souple, réalisée en première intention, dans 61 cas a permis l'extraction de l'EF, dans 83,6% des cas. Le recours à la bronchoscopie rigide a été nécessaire dans 4,9% des cas et à une thoracotomie également dans 4,9% des cas du fait d'une migration distale de l'EF. L'inhalation d’épingle à foulard représente une urgence pneumologique. Les cliniciens doivent être informés de cette forme distincte de corps étrangers intra-bronchiques, son diagnostic et les techniques de son extraction. L'extraction par bronchoscopie souple est une méthode efficace avec un taux de succès élevé. La prévention reste le meilleur traitement. PMID:26958140

    Aspiration of tracheobronchial foreign bodies commonly affects young children, is potentially life threatening and requires early intervention for extraction. Access to facilities and skill manpower for bronchoscopic extraction is however limited in Nigeria. The aim of this study is to describe the experience in our institution with bronchoscopic removal of tracheobronchial foreign bodies and highlight the challenges encountered. This is a retrospective study of all patients referred to the Lagos State University Teaching Hospital with a diagnosis of tracheobronchial foreign body within the period of February 2008 and February 2013. Data extracted from the medical records were age, sex, time interval between aspiration and presentation, location of tracheobronchial foreign body, bronchoscopic technique, complications and outcome. A total of 24 patients were referred and confirmed at bronchoscopy to have tracheobronchial foreign bodies. Mean age was 6.6 + 5 years. Male to female ratio was 1:1. Delayed presentation was common with 22 patients (91.7%) presenting more than 24 hours after aspiration. Aspirated material was inorganic in 17 patients (70.8%) and organic in 7 patients (29.2%). Location of tracheobronchial foreign bodies was right main bronchus in 16 patients (66.7%), left main bronchus in 6 patients (25%) and the trachea in 2 patients (8.3%). Challenges to speedy and safe removal of the foreign bodies were delayed presentation and a limited range of bronchoscopic equipment early in the series which caused prolonged procedures and increased complications. Two mortalities occurred early in the series; one from airway obstruction and the other from respiratory failure caused by tracheobronchial oedema. Extraction of tracheobronchial foreign bodies was faster, more complete and safer later in the series due to a wider range of bronchoscopy equipment which included both flexible and rigid videobronchoscopy with the use of optical forceps.

However, rapid on-site diagnosis is essential for early-stage lung cancer, and in the current work we investigated a new diagnostic illumination nanotechnology.Methods: Tissue samples were obtained from lymph nodes, cancerous tissue, and abnormal intrapulmonary lesions at our interventional pulmonary suites. The following diagnostic techniques were used to obtain the samples: endobronchial ultrasound bronchoscopy; flexible bronchoscopy; and rigid bronchoscopy. Flexible and rigid forceps were used because several of the patients were intubated using a rigid bronchoscope. In total, 30 tissue specimens from 30 patients were prepared. CytoViva® illumination nanotechnology was subsequently applied to each of the biopsy tissue slides.Results: A spectral library was created for adenocarcinoma, epidermal growth factor receptor mutation-positive adenocarcinoma, squamous cell carcinoma, usual interstitial pneumonitis, nonspecific interstitial pneumonitis, typical carcinoid tumor, sarcoidosis, idiopathic pulmonary fibrosis, small cell

    We present a case of an elderly non-smoking gentleman who, since 2005, had been admitted multiple times for recurrent episodes of shortness of breath, wheeze, cough and sputum. The patient was treated as exacerbations of chronic obstructive pulmonary disease (COPD) and\\/or lower respiratory tract infections. Bronchoscopy was done which revealed multiple hard nodules in the trachea and bronchi with posterior tracheal wall sparing. Biopsies confirmed this as tracheopathia osteochondroplastica (TO). He had increasing frequency of admission due to methicillin-resistant Staphylococcus aureus and pseudomonas infections, which failed to clear despite intravenous, prolonged oral and nebulised antibiotics. The patient developed increasing respiratory distress and respiratory failure. The patient died peacefully in 2012. This case report highlights the typical pathological and radiological findings of TO and the pitfalls of misdiagnosing patients with recurrent chest infections as COPD.

    Full Text Available Natalizumab (Tysabri® is a leukocytes chemotaxis inhibitor that decreases the leukocytes passage through the hematoencephalic barrier and it is currently used in relapsing-remitting forms of multiple sclerosis (MS. We present a patient with allergic rhinoconjunctivitis diagnosed with MS who started treatment with natalizumab. She began to show mild asthmatic symptoms until she needed admission to the hospital due to respiratory insufficiency. Blood tests showed peripheral eosinophilia and the thoracic computed tomography scan demonstrated pulmonary infiltrates. The bronchoscopy with the bronchoalveolar lavage resulted in eosinophilic alveolitis. No evidence of bacterial, fungal and parasitic infection, connective tissue disease, or vasculitis were observed. After discontinuation of natalizumab, the patient improved without other treatments. As MS is a prevalent disease and the use of natalizumab is increasing, we consider important to point out that this drug can be associated with pulmonary eosinophilia, especially in patients with allergic rhinoconjunctivitis or asthma.

    Rosell, Jan; Cabras, Paolo

    2013-01-01

    This paper proposes a method for segmenting the airways from CT scans of the chest to obtain a 3D model that can be used in the virtual bronchoscopy for the exploration and the planning of paths to the lesions. The method is composed of 3 stages: a gross segmentation that reconstructs the main airway tree using adaptive region growing, a finer segmentation that identifies any potential airway region based on a 2D process that enhances bronchi walls using local information, and a final process to connect any isolated bronchus to the main airways using a morphologic reconstruction process and a path planning technique. The paper includes two examples for the evaluation and discussion of the proposal.

    Chest trauma is one of the important causes of mortality and morbidity in pediatric trauma patients. The complexity, magnitude, and type of lung injury make it extremely challenging to provide optimal oxygenation and ventilation while protecting the lung from further injury due to mechanical ventilation. Independent lung ventilation is used sporadically in these patients who do not respond to these conventional ventilatory strategies using double-lumen endotracheal tubes, bronchial blocker balloons, etc. However, this equipment may not be easily available in developing countries, especially for pediatric patients. Here, we present a case of severe chest trauma with pulmonary contusion, flail chest, and bronchopleural fistula, who did not respond to conventional lung protective strategies. She was successfully managed with bronchoscopy-guided unilateral placement of conventional endotracheal tube followed by single lung ventilation leading to resolution of a chest injury.

    Full Text Available A 28-year-old female with a history of chronic pancreatitis s/p total pancreatectomy and auto-islet cell transplantation developed a progressively enlarging right neck mass of 4 weeks duration. Coccidioides IgM antibodies were negative and IgG antibodies were positive by immunoassay (EIA, with titers 1:4 by complement fixation (CF. Fine needle aspiration with subsequent excisional biopsy of the right neck mass was performed and showed reactive lymphoid hyperplasia without fungal elements. Bronchoscopy with right upper lobe endobronchial biopsy and 4R lymph node endobronchial ultrasound-fine needle aspiration revealed granulomatous inflammation and Coccidioides spherules on Gomori's methenamine silver stain. Fungal cultures from the right neck mass fine needle aspiration, endobronchial biopsy, and 4R lymph node grew Coccidioides after three weeks of culture.

    2016-01-01

    Full Text Available Purpose: To study the technical feasibility of tracheobronchial stenting via transnasal route under bronchoscopy and fluoroscopic guidance in severe malignant airway strictures using self-expandable nitinol stents. Materials and Methods: We describe three patients with malignant airway strictures, treated entirely via transnasal route under local anesthesia using bronchoscopic and fluoroscopic guidance. Nasal route allowed convenient access to the airway for the bronchoscope across the stricture and a guidewire was introduced through its working channel. The 18F tracheal stent and the 6F bronchial stent assembly could be easily introduced and deployed under bronchoscopic (reintroduced through the other nostril and fluoroscopic guidance. Results: We achieved technical success in all the three patients with immediate relief of dyspnea. Conclusion: Transnasal airway stenting with self-expandable nitinol stent using bronchoscopic and fluoroscopic guidance under local anesthesia is a safe and effective method with minimal patient discomfort.

    A 14-year-old boy neurologically impaired was scheduled for tracheostomy under general anesthesia because of the prolonged tracheal intubation. He had twice received artificial respiration under tracheal intubation for aspiration pneumonia. During emergence from anesthesia, bucking occurred and suddenly the patient's lungs could not be ventilated. Neither anesthetic circuit nor tracheostomy tube were not functioning well, and airway obstruction was not relieved by manual and positive pressure ventilation within 40 mmHg. SpO2 gradually decreased to 48%, resulting in bradicardia. However, it became possible to inflate the lungs immediately because of the respiratory effort decreased. SpO2 rapidly increased to normal range and heart rate recovered. The patient was suspected of having tracheomalacia as a result of flexible bronchoscopy performed through tracheostomy tube, revealing slight collapse of the trachea. Tracheomalacia can be a cause of sudden difficult ventilation in neurologically impaired children.

  12. Tracheobronchial Foreign Body Aspiration: Dental Prosthesis

    2014-01-01

    Full Text Available It is important to extract foreign bodies for avoiding life-threatening complications. They can lead to death if they are not treated. Different signs and symptoms could occur according to the complete or partial airway obstruction. Foreign body aspiration is a rare incident in adults. The organic foreign materials such as foods are found to be aspirated more commonly and are usually settled in the right bronchial system. However, dental prosthesis and teeth aspirations are rare in literature. In our study, a 52-year-old male patient who had aspirated the front part of his lower dental prosthesis accidentally is presented and the foreign body is extracted by using rigid bronchoscopy. There are many causes of aspiration but dental prosthetic aspirations should be kept in mind during sleep. For this reason, dental apparatus must be taken out while asleep.

    Keiko Mitaka Komatsuzaki

    2014-01-01

    Full Text Available A 33-year-old woman was admitted for a pseudocroup-like cough and wheezing after general anesthesia. Several months ago, she had undergone cardiac re-operation and turbinectomy, both of which had involved difficult intubations. Bronchoscopy indicated a pin-hall-like subglottic stenosis; therefore, emergency tracheotomy was performed. Six years later, a computed tomography scan demonstrated progressive stenosis of the entire circumference of the trachea and main bronchi. She died at 40 years. Her autopsy revealed marked tracheobronchial stenosis. She had many medical histories that had gone undiagnosed and had been clinically ill with only heart defects. She did not have coloboma but had microphthalmos, atresia choanae, retarded growth development, and deafness; thus, we diagnosed CHARGE syndrome that refers to multiple congenital anomalies, including airway abnormalities, which can lead to secondary complications such as traumatic stenosis after intubation. Physicians should have knowledge of this rare disease and should pay special attention to potential airway problems.

  14. Anesthetic Management of Direct Laryngoscopy and Dilatation of Subglottic Stenosis in a Patient with Severe Myasthenia Gravis

    Directory of Open Access Journals (Sweden)

    Hesham A. Elsharkawy

    2012-01-01

    Full Text Available We describe the anesthetic management of a patient with severe myasthenia gravis and tracheal stenosis; the patient was scheduled for direct laryngoscopy and dilatation. The combination of myasthenia gravis and tracheal obstruction presents several difficulties for anesthetic management. The airway is shared; therefore, any complications are also shared by the anesthesiologist and bronchoscopists. The potential for respiratory compromise in patients undergoing the two procedures requires that anesthesiologists be familiar with the underlying disease state, as well as the interaction of anesthetic and nonanesthetic drugs in a case involving myasthenia gravis. We reviewed the literature and report our experience in this case. There is no strong evidence for choosing one approach to general anesthesia over another for bronchoscopy. Careful preoperative planning and experience in airway management and jet ventilation are crucial to prevent an adverse outcome and obtain favorable results.

    managing those changes. OBJECTIVES: To describe the endoscopic abnormalities found in the airway mucosa of a group of patients with WG undergoing bronchoscopy at Hospital das Clínicas of the Faculdade de Medicina, Universidade de São Paulo (HC-FMUSP, and to report the therapeutic bronchoscopic interventions used in some cases. METHODS: The study assessed 15 patients diagnosed with GW from the Vasculitis Outpatient Clinic of the Department of Pulmonology, HC-FMUSP, referred for bronchoscopy at the Service of Respiratory Endoscopy, HC-FMUSP, from 2003 to 2007. RESULTS: Fifteen patients were studied [11 females (73.33%]; mean age, 34 ± 11.5 years. Airway changes were found in 80% of the patients, and the most frequent endoscopic finding was subglottic stenosis (n = 6. Therapeutic bronchoscopy was performed in three patients with subglottic stenosis and in other three patients with bronchial stenosis, all showing good results. CONCLUSION: Bronchoscopy allows for diagnosing, monitoring, and treating the airway lesions in WG, being a minimally invasive therapeutic option in selected cases.

    Five articles and an editorial on interventional pneumology were published in Archivos de Bronconeumología. Two of these articles deal with bronchoscopy, one with lung biopsy with cryoprobes, one with thermoplasty in asthma and the last with tracheobronchomalacia. We also review several publications in international journals, with special emphasis on endobronchial ultrasound. Four original articles on idiopathic pulmonary fibrosis were published in Archivos de Bronconeumología: one special article comparing two treatments and a Cochrane systematic review on the efficacy of non-steroidal drugs in this disease. Finally, we highlight studies in lung transplantation, consisting of 14 publications from different continents and with highly diverse contents: one editorial, one letter to the editor, one procedures manual and nine international publications on donor characteristics, various types of complications, experimental results in the field of preservation, and the casuistics obtained in distinct diseases in which transplantation is an option.

    Hamartomas are very rarely identified as an endobronchial lesion. Herein, we describe a peculiar case of a 55-year-old woman with persistent cough and increasing dyspnea and radiological detection of a solid lesion subtotally occluding the main right bronchus. Despite the radiological and radiometabolic (18-fluoro-2-deoxy-d-glucose positron emission tomography/computer tomography scan) features were highly suspected for bronchial carcinoid, the definitive diagnosis after endoscopic removal was indicative of an endobronchial hamartoma. When considering differential diagnosis of an endobronchial lesion, the physicians should take firmly in mind such rare entity and, accordingly, bronchoscopy and bronchoscopic biopsy should be done as first step in management of all cases presenting with endobronchial lesions.

    2009-03-01

    Aspiration of a tooth in maxillofacial injuries is a known complication necessitating prompt recognition and early treatment to minimize potentially serious and, sometimes, even fatal consequences. Here, we report a rare and unusual case in its presentation, the patient having aspirated 2 permanent teeth after maxillofacial, cervical vertebrae, and thoracic region crush injuries due to a motor vehicle accident. The diagnosis of teeth aspiration was delayed until 2 weeks after the event. An aspirated anterior tooth was expectorated by the patient himself, and the other aspirated anterior tooth was removed by flexible bronchoscopy. The paper also emphasizes that clinicians must be aware of dental injury resulting from maxillofacial injuries and account for all teeth as part of their evaluation, keeping an open mind as to where a missing tooth might be located. A rapid diagnosis depends on high clinical suspicion, clinical signs, and radiologic findings.

  20. Diffuse bronchiectasis as the primary manifestation of endobronchial sarcoidosis

    2017-01-01

    Full Text Available Sarcoidosis is an idiopathic disease that most commonly involves the lungs and is characterized by granulomatous inflammation. Bronchiectasis is one pulmonary manifestation of sarcoidosis, although it is almost always observed as traction bronchiectasis in the setting of fibrotic lung disease. A 50-year-old woman was evaluated for chronic cough and bronchiectasis with a small amount of peripheral upper lobe honeycombing and no significant pulmonary fibrosis or lymphadenopathy. After an extensive laboratory and imaging evaluation did not identify a cause of her bronchiectasis, bronchoscopy was performed to assess for primary ciliary dyskinesia and revealed a diffuse cobblestone appearance of the airway mucosa. Endobronchial biopsies and lymphocyte subset analysis of bronchoalveolar lavage fluid were consistent with a diagnosis of sarcoidosis. We believe endobronchial sarcoidosis should be included in the differential diagnosis of patients presenting with bronchiectasis.

    Full Text Available Craniofacial abnormalities in pediatric population fall under the category of expected case of difficult airway. We present here a case of large maxillary tumor in a 9-year-old girl where the relative difficulty was further compounded due to her noncooperation which was again expected from a child. Local anesthetic topicalization of airway followed by slow inhalational induction with gradually increasing sevoflurane, while maintaining her spontaneous breathing, we secured her airway using fiber optic bronchoscopy. The surgery and the extubation went uneventful. In conclusion a planned airway management using fiber optic bronchoscope after airway topicalization and sevoflurane induction is the ideal technique in an expected case of difficult pediatric airway.

    A 62-year-old man with pain in his hip joints and back was admitted to our hospital. His chest radiograph and CT showed a huge mass extending from the left upper pericardium to the left hilum, but no pleural effusion or other lesions. A contrast-enhanced abdominal CT showed multiple metastases to bones and both kidneys. Bronchoscopy revealed obstruction of the left B3 by a visible tumor. The biopsy specimens of the initial immunohistochemical staining were slightly positive for calretinin. However, we diagnosed the condition as sarcomatoid carcinoma of the lung on the basis of the clinical evaluation. Although radiotherapy was administered, his condition rapidly deteriorated and he died due to progression of the disease. Autopsy revealed extensive invasion, suggesting mesothelioma. Therefore, immunohistochemical staining was performed; the findings revealed sarcomatoid malignant mesothelioma. In conclusion, we encountered a rare case of sarcomatoid malignant mesothelioma (stage IV).

    Full Text Available The present report describes a 60-year-old Caucasian woman who presented with progressive dyspnea, cough and wheeze. A computed tomography scan of the chest showed innumerable bilateral inflammatory pulmonary nodules with bronchovascular distribution and a mediastinal and hilar infiltrative process with calcified lymphadenopathy leading to narrowing of lobar bronchi and pulmonary arteries. An echocardiogram revealed pulmonary hypertension. Bronchoscopy showed left vocal cord paralysis and significant narrowing of the bilateral bronchi with mucosal thickening and multiple nodules. Transbronchial biopsy was compatible with sarcoidosis. Despite balloon angioplasty of the left lower lobe and pulmonary artery, and medical therapy with oral corticosteroids, her symptoms did not significantly improve. To the authors’ knowledge, the present report describes the first case of pulmonary sarcoidosis resulting in major airway, vascular and nerve compromise due to compressive lymphadenopathy and suspected concurrent granulomatous infiltration. Its presentation mimicked idiopathic mediastinal fibrosis.

    Full Text Available Neurofibromatosis or von Recklinghausen's disease is the most common inherited syndrome predisposing to neoplasia. Carcinosarcoma is a rare malignant mixed tumor of the lung. Association of carcinosarcoma of lung with Neurofibromatosis-1 is not common. A 57-year-old man presented with history of fever, cough, hemoptysis, breathlessness, weight loss, chest pain. Multiple cutaneous neurofibromas and café au lait spots were revealed by physical examination. A homogeneous opacity was found in the right middle and right upper zone on posterior-anterior chest radiography. A 8x8x7 cm mass that had irregular borders in right upper posterior and apical segment was seen on contrast enhanced chest computed tomography. On bronchoscopy, the lumen of right upper apical segment was obstructed with vegetating tumoral lesion. The biopsy taken from this region was diagnosed as carcinosarcoma by histopathological and immunohistochemical examination.A rare case with carcinosarcoma of the lung and Neurofibromatosis-1 was reported.

    Full Text Available Introduction:Spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in DM than PM. complications of dermatomyositis (DM and polymyositis (PM, both of which can be fatal. Case Report:A 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever. She had been diagnosed with dermatomyositis 21 months prior. A thorax computed tomography (CT scan revealed ground glass opacities in her lungs, pneumomediastinum, pneumothorax, and subcutaneous emphysema. Despite intensive immunosuppressive therapy, clinical deterioration and radiological progression were observed, ultimately the patient died. Conclusion:During the care for a patient with dermatomyositis, the otorhinolaryngologist should be cautious of rapidly progressive and fatal neck subcutaneous emphysema. For a patient with dermatomyositis and with normal bronchoscopy and esophagoscopy, the main treatment is control of dermatomyositis with medical therapy. Therefore, a tracheostomy and/or mechanical ventilation may not be necessary.

    2012-01-01

    Idiopathic pulmonary fibrosis (IPF) is a devastating disease affecting the distal lung, due to failure of the alveolar epithelium to heal after micro-injuries, leading to inefficient gas exchange and resulting in death. Therapeutic options are very limited. A new therapeutic approach based on gene therapy restores the self-healing process within the lung in the experimental setup. A basic requirement of this therapy is the successful transduction of genes into the alveolar epithelium in the distal part of the lung, for which a new therapeutic instrument is required. In this paper we present the concept and first experimental results of a device which uses an electrical field to accelerate the charged droplets of plasmid suspension toward the tissue and which overcomes cell membrane with its impact energy. The aim is to develop a therapeutic device capable of being integrated into minimally invasive procedures such as bronchoscopy.

    Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphadenopathy. A diagnostic bronchoscopy was performed where an incidental tracheal nodule was discovered and biopsied. Pathology was consistent with epithelial-myoepithelial carcinoma. Lymph node biopsy demonstrated non-caseating granulomas consistent with sarcoidosis. Patient underwent tracheal resection of the primary tumor with primary tracheal reconstruction. Hypercalcemia subsequently normalized with clinical improvement. Repeat CT imaging demonstrated complete resolution of lymphadenopathy. Our findings are suggestive of a possible paraneoplastic sarcoid-like reaction to the epithelial-myoepithelial carcinoma with associated lymphadenopathy and symptomatic hypercalcemia.

    Diffuse alveolar hemorrhage (DAH) is a life-threatening complication that occurs in association with various diseases including coagulation disorders. In rare cases, it is caused by hemophilia. A 48-year-old man was admitted to our hospital for a third time due to DAH. Although the cause of DAH could not be identified by bronchoscopy or laboratory tests, a good response to corticosteroids suggested idiopathic DAH with pulmonary capillaritis. The patient was diagnosed with hemophilia B based on the results of a detailed inquiry, a mildly prolonged activated partial thromboplastin time, and low factor IX activity. Hemophilia may be an underlying factor that exacerbates the bleeding of patients with DAH, even when they show a good response to corticosteroids. PMID:28202865

    2016-03-01

    A 31-yr-old male Sumatran orangutan (Pongo abelii) presented with 14 yr of chronic purulent nasal drainage and cough with intermittent exacerbation of symptoms requiring systemic antibiotic treatment. He was diagnosed with a cystic fibrosis (CF)-like condition. Evaluation consisted of bronchoscopy with bronchoalveolar lavage, culture, and computed tomography scanning of the sinuses and chest. Although the presence of low fecal elastase activity increased the suspicion for a diagnosis of CF, pilocarpine iontophoresis with sweat collection and analysis ("sweat testing") was inconclusive. Medical management included twice-daily nebulization with bronchodilators and alternating month inhaled antibiotics, pancreatic enzyme replacement therapy, and simethicone as needed. Sinopulmonary and gastrointestinal symptoms improved substantially with treatment. Several years later, the animal died acutely of colonic volvulus. Necropsy and histopathology confirmed CF-like lung disease with chronic air sacculitis.

    To study the prevalence of beryllium sensitization (BeS) and chronic beryllium disease (CBD) in a cohort of workers from a nuclear weapons research and development facility. We evaluated 50 workers with BeS with medical and occupational histories, physical examination, chest imaging with HRCT (N=49), and pulmonary function testing. Forty of these workers also underwent bronchoscopy for bronchoalveolar lavage (BAL) and transbronchial biopsies. The mean duration of employment at the facility was 18 yrs and the mean latency (from first possible exposure) to time of evaluation was 32 yrs. Five of the workers had CBD at the time of evaluation (based on histology or HRCT); three others had evidence of probable CBD. These workers with BeS, characterized by a long duration of potential Be exposure and a long latency, had a low prevalence of CBD.

    A 15-year-old domestic shorthair feline immunodeficiency virus-positive cat was presented with a five day history of productive cough and acute respiratory distress. Physical examination revealed inspiratory dyspnoea and diffuse gingivostomatitis. Radiographs showed an intratracheal mass located at the level of the sixth and the seventh cervical vertebrae. Bronchoscopy revealed a unique intratracheal mass occluding about 85 per cent of the tracheal lumen. The tracheal mass was removed bronchoscopically. A diagnosis of pyogranulomatous inflammation referable to a mycobacterial infection was made based on cytological and histopathological findings. 16S rRNA polymerase chain reaction testing and sequence analysis identified a novel mycobacterial species, likely a slow grower, with 95 per cent identity with Mycobacterium xenopi. To our knowledge, this is the first description of a tracheal mycobacterial granuloma in a cat, and the first time, a mycobacterium with this sequence has been identified.

    The development of a postoperative respiratory insufficiency is typically caused by several factors and include patient-related risks, the extent of the procedure and postoperative complications. Morbidity and mortality rates in acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are high. It is important to have consistent strategies for prevention and preoperative conditioning is essential primarily for high-risk patients. Treatment of established postoperative lung failure requires early tracheotomy, protective ventilation (tidal volume 6 ml/kg body weight), elevated positive end expiratory pressure (PEEP, 10-20 mmH2O), recurrent bronchoscopy and early patient mobilization. In critical cases an extracorporeal lung assist is considered to be beneficial as a bridge to recovery and for realizing a protective ventilation protocol. Different systems with separate indications are available. The temporary application of a lung assist allows thoracic surgery to be performed safely in patients presenting with insufficient respiratory function.

    Full Text Available A 59 year old female was admitted to the ICU with hypoxemic respiratory failure and a clinical picture of ARDS (Figure 1, requiring intubation and mechanical ventilation. She underwent bone marrow and renal transplantation several years prior for multiple myeloma and myeloma kidney, respectively. She had been restarted on lenalidomide one month prior to presentation. She was also taking tacrolimus, mycophenolate, prophylactic antimicrobials, warfarin for deep venous thrombosis, and aspirin for coronary artery disease. Emergent bronchoscopy with bronchoalveolar lavage revealed progressively bloodier specimens (Figure 2 consistent with diffuse alveolar hemorrhage (DAH. Further work-up was negative for vasculitis. Her lenalidomide, anticoagulation, and trimethoprim/sulfamethoxazole was stopped. She was started on high dose steroids and improved over 2 weeks.

    2009-06-01

    Full Text Available Abstract Introduction Two cases of iatrogenic tension pneumothorax in children are reported. Case presentations Case 1: A 2-year-old boy with suspected brain death after suffering multiple trauma suddenly developed intense cyanosis, extreme bradycardia and generalized subcutaneous emphysema during apnea testing. He received advanced cardiopulmonary resuscitation and urgent bilateral needle thoracostomy. Case 2: A diagnostic-therapeutic flexible bronchoscopy was conducted on a 17-month-old girl, under sedation-analgesia with midazolam and ketamine. She very suddenly developed bradycardia, generalized cyanosis and cervical, thoracic and abdominal subcutaneous emphysema. Urgent needle decompression of both hemithoraces was performed. Conclusion In techniques where gas is introduced into a child's airway, it is vital to ensure its way out to avoid iatrogenic tension pneumothorax. Moreover, the equipment to perform an urgent needle thoracostomy should be readily available.

    sedation. Follow-up included repeat bronchoscopy every 6 months and chest CT every year. Results. Ten patients aged 24 to 70 years with endobronchial carcinoid were treated. The tumor location was variable: 2 left Main bronchus, 1 left upper lobe bronchus, 2 right main bronchus, 2 right middle lobe bronchus and 3 right lower lobe bronchus. No major complications were observed. The patients required between 2 and 4 procedures. Patients were followed for a median period of 29 months with no evidence of tumor recurrence. Conclusions. Endobronchial laser photoresection of typical bronchial carcinoids using flexible bronchsocopy under conscious sedation is an effective treatment modality for a subgroup of patients that provides excellent long-term results that are similar to outcome obtained by more invasive procedures.

    C. Hornuss

    2010-01-01

    Full Text Available A 47-year-old man with a history of heart transplant was admitted after severe traumatic brain injury and seizures. During mechanical ventilation, the patient developed bronchospasm that severely compromised respiratory function that led to cardiac arrest. After resuscitation, application of isoflurane through the Anaesthetic Conserving Device (AnaConDa in the ICU successfully treated bronchospasm, provided adequate sedation, and enabled appropriate ventilation and diagnostic bronchoscopy. A subsequent bronchoalveolar lavage revealed a high amount of Herpes simplex DNA. Herpes simplex pneumonia was diagnosed and treated with acyclovir. Isoflurane treatment was applied for twelve days total without side effects on renal and cerebral function. The patient recovered quickly after the termination of sedation. At discharge, he was fully awake without focal neurological deficiency and his long-term outcome was excellent. This case demonstrates that isoflurane is a treatment option in life-threatening cases of bronchospasm and a safe option for long-term sedation.

    Full Text Available A 2-year-old male with Poland-Moebius syndrome was transferred from a local hospital to the Pediatric ICU at Children’s Hospital of Georgia for suspected postobstructive pulmonary edema (POPE after tonsillectomy/adenoidectomy (T&A. The patient’s respiratory status ultimately declined and he developed respiratory failure. Imaging suggested pulmonary edema as well as a left-sided pneumonia. Echocardiogram showed pulmonary hypertension and airway exam via direct fiberoptic bronchoscopy revealed tracheomalacia and bronchomalacia. He developed acute respiratory distress syndrome (ARDS and remained intubated for ten days. This case highlights the association between congenital upper body abnormalities with cranial nerve dysfunction and the development of POPE with delayed resolution of symptoms. Patients with upper body abnormalities as above are at great risk of postoperative complications and should therefore be managed in a tertiary-care facility.

    Pulmonary edema of non-cardiac origin is usually an urgent clinical problem, which has recently increased in frequency throughout the world in the past few years. This is partly due to sociological factors and to pre-eminent advances in industrial technology. Recent severe massive toxic gas explosions have had national and worldwide implications. Therefore, urgent and appropriate therapy is of utmost importance in most of these patients. The use of high flow oxygen with Constant Positive Pressure Breathing are the main inhalational therapeutic approaches. Newer modalities of treatment include: (1) earlier Fiberoptic bronchoscopy in those individuals afflicted with aspiration problems and (2) certain specific chemical blocking agents for the management of phosgene intoxication and hydrogen sulfide toxicity. Preventive environmental measures are also important.

    A five-year-old girl developed hoarseness with gradual worsening at the age of eight months. Three months later, she underwent bronchoscopy in which papillomas in the vocal cords, larynx and trachea were observed. Because of serious bronchospasm crises and respiratory failure, she needed several hospitalizations, definitive tracheostomy and multiple endoscopic procedures for papilloma excision. The most recent chest radiography (Figure A) and computed tomography (CT) scans (Figures B and C) showed a nodule inside the trachea and multiple pulmonary nodules, cysts and consolidations. The anatomopathological findings from curettage of the lesions revealed benign squamous-cell papillomas. Recurrent respiratory papillomatosis (RRP) is directly related to the human papillomavirus (HPV). Its spread to the lower airways is uncommon, with involvement of trachea and/or proximal bronchi in 5% of the patients, and extension to the lungs in only 1% of the cases. (author)

  3. Chest trauma: A case for single lung ventilation

    Full Text Available Chest trauma is one of the important causes of mortality and morbidity in pediatric trauma patients. The complexity, magnitude, and type of lung injury make it extremely challenging to provide optimal oxygenation and ventilation while protecting the lung from further injury due to mechanical ventilation. Independent lung ventilation is used sporadically in these patients who do not respond to these conventional ventilatory strategies using double-lumen endotracheal tubes, bronchial blocker balloons, etc. However, this equipment may not be easily available in developing countries, especially for pediatric patients. Here, we present a case of severe chest trauma with pulmonary contusion, flail chest, and bronchopleural fistula, who did not respond to conventional lung protective strategies. She was successfully managed with bronchoscopy-guided unilateral placement of conventional endotracheal tube followed by single lung ventilation leading to resolution of a chest injury.

    Common variable immunodeficiency (CVID) is the most common of the primary immunodeficiency disorders. Pulmonary manifestations are characterised by recurrent rhinosinusitis, respiratory tract infections and bronchiectasis. Less commonly the lung may be affected by lymphoid disorders and sarcoid-like granulomas. Organising pneumonia (OP) is a rare pulmonary manifestation. We report the case of a 32-year-old woman with CVID who presented with fever, dyspnoea and persistent lung infiltrates despite antibiotic therapy. CT of the chest showed bilateral patchy alveolar infiltrates. Pulmonary function tests revealed moderate restriction and reduction in diffusion capacity. Initial bronchoscopy with transbronchial biopsies did not yield a diagnosis but surgical lung biopsies identified OP. Significant clinical, radiographic and physiological improvement was achieved after institution of corticosteroid therapy.

  5. Lobar Collapse and Obliteration of Air Bronchogram Allowing Early Diagnosis of Endobronchial Aspergillus Infection following Hematopoietic Stem Cell Transplantation

    2014-01-01

    Full Text Available Endobronchial fungal infection (EBFI is notoriously difficult to diagnose early since it may present few systemic features and does not cause characteristic parenchymal lesions on lung CT scanning. We report a 9-year-old girl who suffered extended neutropenia following graft failure after haematopoietic stem cell transplantation (HSCT for severe aplastic anaemia. CT scan prior to retransplantation was normal despite persistent cough but lobar collapse was shown on repeat scan 16 days later. The probable diagnosis of EBFI (later proven on bronchoscopy was only suspected when subsequent chest X-ray (CXR demonstrated lack of an air bronchogram in the partially collapsed lung. Early radiological suspicion resulted in multiagent antifungal therapy followed by delayed lobectomy, and led to this being the first reported case of Aspergillus EBFI not to result in respiratory failure.

    Ciet, P.; Wielopolski, P.; Lever, S.

    Purpose: TM is an excessive narrowing of the intrathoracic part of the trachea. TM is a common congenital pediatric anomaly, but it’s often not recognized due to its unspecific clinical presentation. The aims of our study are: 1) to develop cine-MRI sequences to visualize central airways in static...... spirometry controlled breathing maneuvers (peak flow and coughing) using a MRI compatible spirometer. “Static” 13-second breath-hold scans covering the entire thoracic region were acquired at end-inspiration and end-expiration using a 3D GRE with TR/TE=1.2/0.5 ms, alpha = 2, sagittal isotropic volume (2.8) x...... breathing maneuvers. Images of central airways during static and dynamic conditions were acquired and could be analyzed. Three out of the 8 children had a TM just above the carina during forced expiration, confirmed by bronchoscopy. Conclusion: This pilot study shows that Dynamic-MRI is feasible...

  7. Metastatic melanoma after 23 years of primary ocular melanoma.

    2016-11-23

    We describe a case of 52-year-old man who presented with an episode of tonic-clonic seizures. He had right ocular melanoma 23 years ago with subsequent enucleation which was the standard treatment at that time. CT scans of the brain and of the thorax-abdomen-pelvis revealed widespread metastatic lesions in the brain, lung and liver. Further investigations including bronchoscopy with cytopathology uncovered that the metastatic disease was a recurrence of ocular melanoma. He received palliative radiotherapy and died 6 months later. Ocular melanoma is often associated with fulminant metastatic disease after a period of dormancy. Thus, despite successful treatment of the localised disease at initial presentation, an effort is needed for optimal long-term follow-up plan in order to improve survival in case of recurrence.

    Full Text Available Background. The control of severe bronchial asthma, such as corticosteroid-resistant asthma, is difficult. It is also possible that immunosuppressive agents would be effective for bronchial asthma. Case Summary. A 55-year-old Japanese female presented with severe bronchial asthma controlled with tacrolimus. She had been diagnosed with bronchial asthma during childhood. Her asthma worsened, and a chest radiograph showed atelectasis of the left lung. Bronchoscopy revealed the left main bronchus to be obstructed with viscous sputum consisting of 82% neutrophils and no eosinophils. The atelectasis did not improve with corticosteroid treatment, but was ameliorated by administration of tacrolimus. Discussion. This patient had severe asthma due to neutrophilic inflammation of the airways. Tacrolimus is effective for treating severe asthma, for example, in corticosteroid-resistant cases.

    Full Text Available It is important to assess patients of difficult/therapy resistant asthma carefully in order to identify whether there are any correctable factors that may contribute to their poor control. It is critical to make a diagnosis of asthma and to exclude other airway diseases. A 65-years-old lady presented with repeated acute episodes of dyspnoea and wheezing. She was on regular medication for bronchial asthma for 18 years. There was no history of foreign body aspiration or loss of consciousness. Her chest radiograph was normal. She showed poor response to corticosteroids and bronchodilators. Fibreoptic bronchoscopy (FOB showed intracordal cyst of the left vocal cord and 1cm size irregular piece of betel nut in right main bronchus, which was removed endoscopically with the help of dormia basket, following which her condition improved and asthma was controlled on inhaled bronchodilators.

    2015-11-01

    Full Text Available A 65-year-old man with right central type of lung squamous carcinoma was admitted to our department. Bronchoscopy displayed complete obstruction of right upper lobe bronchus and infiltration of the bronchus intermedius with tumor. Chest contrast computed tomography revealed the tumor invaded right pulmonary artery, superior vena cava, and the persistant left superior vena cava flowed into the coronary sinus. The tumor was successfully removed by means of bronchial and pulmonary artery sleeve resection of the right upper and middle lobes combined with resection and reconstruction of superior vena cava (SVC utilizing ringed polytetrafluoroethylene graft. To the best of our knowledge, this was the first report of complete resection of locally advanced lung cancer involving superior vena cava, right pulmonary artery trunk and main bronchus with persistant left superior vena cava.

    2014-01-01

    Background: Pulmonary hamartomas are rare benign tumors of the lung with an incidence of 0.025%-0.32%. Endobronchial benign lesions can cause bronchial obstruction and recurrent respiratory infections or obstructive pneumonia and recurrent hemopthysis. Case report: A 66-year-old male with recurrent hemoptysis and pneumonias for a year, was referred to our department for an endoscopic resection of an endobronchial hamartoma. Initially he refused any intervention but, as he suffered additional episodes of hemoptysis and chest infections during a year on follow up, he finally underwent interventional bronchoscopy and the lesion was cauterized using snare electrocautery probe and removed with cryoextraction. The patient has been followed for two years in our outpatient clinic, with no further problems. Conclusion: Endoscopic treatment with flexible bronchoscope, electrocautery and cryotherapy provides an excellent outcome. Surgical therapy, should be reserved for the hamartomas that cannot be approached through endoscopy. Hippokratia 2014; 18 (4): 355-356. PMID:26052204

    Full Text Available Primary tracheal tumors are rare, and composed of variousbenign and malignant pathologies. They often cansimulate obstructive pulmonary diseases, such as asthmaand chronic obstructive pulmonary disease, and patientswith malign tracheal tumors sometimes undergolong-term treatment for such diseases, without any improvement.Therefore, these tumors should be includedin the differential diagnosis in patients presenting tracheobronchialtree obstruction. We present a squamous cellendotracheal carcinoma case that had received treatmentwith a diagnosis of chronic obstructive pulmonarydisease for a long time. The recent increase in symptomshad been thought to be due to an exacerbation of the disorderbut the bronchoscopy performed after 3 months ofno improvement revealed an endotracheal mass lesion.Full recovery was obtained with bronchoscopic resectionof the tumor.Key words: Endotracheal tumor, chronic obstructive pulmonary disease, squamous cell carcinoma

  13. Thromboelastometric Profiles of Horses Affected by Exercise-Induced Pulmonary Hemorrhages

    Directory of Open Access Journals (Sweden)

    Alessia Giordano

    2010-01-01

    Full Text Available Exercise-induced pulmonary hemorrhage (EIPH commonly occurs in race horses. Thromboelastometry (TEM investigates the whole hemostatic process by evaluating the viscoelastic properties of the blood clot from its formation to fibrinolysis. The aim of this study was to assess whether horses with EIPH have abnormal thromboelastometric profiles. Intrinsic and extrinsic pathways, fibrinogen activity and fibrinolysis were investigated by TEM before and after the race in negative controls and in horses on which EIPH was confirmed by bronchoscopy. Compared with controls, horses with EIPH had an increased coagulability in both pre- and postrace samplings, especially for the intrinsic pathway and for the fibinrolytic activity. These results suggest that coagulation is preactivated in horses prone to develop EIPH, possibly due to recent or recurrent hemorrhage.

    Full Text Available Direct injury to airway is a rare event and also a challenge to anaesthesiologist and surgeon. We present a case report of open tracheal injury with right pneumothorax in a young male following assault with a sharp weapon. In spite of a chest tube in situ, the patient came with collapse of one lung and tachypnoea which required surgical exploration. Lower airway was evaluated by fibre-optic bronchoscopy through the open tracheal wound while he was awake and tracheal tube was passed over the bronchoscope. There was no vascular or oesophageal injury detected. Although there was a pleural tear, there were no signs of injury to lung parenchyma. After evaluation, end to end anastomosis of the trachea was planned, for which orotracheal tube was passed with surgical assistance. Patient was shifted to post-operative high dependency unit and was electively ventilated for 7 days and was later successfully extubated under fibre-optic bronchoscope guidance.

    2013-01-01

    Full Text Available An 83-year-old male presented with dyspnoea and stridor. He had undergone pneumonectomy 40 years ago. CT scan revealed gross shift of mediastinum (post-pneumonectomy syndrome with tortuous trachea kinked at the thoracic inlet. Fibre optic bronchoscopy showed a near total expiratory closure of trachea, right main bronchus, and segmental bronchi confirming tracheobronchomalacia. He was managed with long length, low tracheostomy in view of his poor general condition of permitting more invasive procedures. He showed adequate clinical improvement and was discharged home. Tracheobronchomalacia in post-pneumonectomy syndrome requires emergent management. Its occurrence after 40 years is very rare and may be easily missed. It can be diagnosed with dynamic CT and FOB. Although invasive management with stenting or surgical methods is routinely advised, conservative care can be effective in selected cases.

    Extrinsic airway compression due to chest wall deformity is not commonly observed. Although this condition can be diagnosed more easily with the help of multidetector CT, the standard treatment method has not yet been definitely established. We report a case of an eighteen-year-old male who suffered from severe extrinsic tracheal compression due to scoliosis and straightening of the thoracic spine, confirmed on CT and bronchoscopy. The patient underwent successful placement of tracheal stent but later died of bleeding from the tracheostomy site probably due to tracheo-brachiocephalic artery fistula. We describe the CT and bronchoscopic findings of extrinsic airway compression due to chest wall deformity as well as the optimal treatment method, and discuss the possible explanation for bleeding in the patient along with review of the literature.

Dermatologist opined the skin lesions as acanthosis nigricans. He was referred to our department to evaluate for any underlying internal malignancy as he was a smoker. His chest X-ray revealed right sided hilar prominence with a mid zone cavity with fluid level. Fibreoptic bronchoscopy was done, there was one ulcerative growth in right middle lobe bronchus. Biopsy from the ulcer revealed probable squamous cell carcinoma. CT scan of thorax was also done and CT guided FNAC of Rt lung lesion yielded non small cell carcinoma. His skin lesions were also biopsied and diagnosis of acanthosis nigricans was confirmed. Here we report a case of acanthosis nigricans associated with non-small cell cancer of lung.

    Exophiala dermatitidis pneumonia is extremely rare. Here we report a case of E. dermatitidis pneumonia successfully treated with long-term itraconazole therapy. A 63-year-old woman without a remarkable medical history developed a dry and chest pain. Chest radiographs revealed consolidation in the middle lobe of the lung. Cytologic examination by bronchoscopy showed filamentous fungi and E. dermatitidis was detected in the bronchoalveolar lavage fluid. After 5 months of itraconazole therapy, her symptoms improved and the area of consolidation diminished. Two weeks after discontinuing the itraconazole therapy, the area of consolidation reappeared. Itraconazole therapy was restarted and continued for 7 months. The abnormal shadow observed on the chest X-ray gradually diminished. Over a 27-month follow-up with periodic examination, there was no relapse and the patient had a favorable clinical course.

A 54 year-old man with a past medical history significant for traumatic brain injury and aspiration pneumonia presented with hypoxic respiratory failure secondary to foreign body aspiration. On presentation, the patient was found to be hypoxic and tachypneic, requiring endotracheal intubation and mechanical ventilation. Bronchoscopy was performed with removal of extensive food particles throughout both lungs. The patient subsequently developed sepsis secondary to aspiration pneumonia. He became hypotensive, requiring central venous catheter placement for vasopressor therapy. A right subclavian central line was attempted under ultrasound guidance. A beside ultrasound was subsequently performed (Video 1. What does the video obtained of a longitudinal view of the IVC at the level of the liver demonstrate? 1. Endocarditis; 2.

    Full Text Available Insufficient coordination of medical research and partial isolation from the international scientific community can result in application of invasive methods without sufficient indications. Here is presented an overview of renal and pancreatic biopsy studies performed in the course of the operations of pancreatic blood shunting into the systemic blood flow in type 1 diabetic patients. Furthermore a surgical procedure of lung denervation as a treatment method of asthma as well as the use of bronchoscopy for research in asthmatics are discussed here. Today, the upturn in Russian economy enables acquisition of modern equipment; and medical research is on the increase. Under these circumstances, the purpose of this letter was to remind that, performing surgical or other invasive procedures, the risk-to-benefit ratio should be kept as low as possible.

    Full Text Available Endobronchial tuberculosis (EBTB is a sequelae of pulmonary tuberculosis (TB that extends to the endobronchial or endotracheal wall causing inflammation, edema, ulceration, granulation or fibrosis of mucosa and submucosa. This case depicts a 20 year old foreign-born woman with a history of active pulmonary TB on anti-TB chemotherapy, who presented with worsening stridor, dyspnea, cough and weight loss. The disease state was diagnosed with multiple modalities including, spirometry, CT scan of the neck, and bronchoscopy. The biopsies of the tracheal web revealed fibrotic tissue without any granulomas or malignancy establishing the diagnosis of EBTB. Serial balloon dilations and anti-neoplastic therapy with Mitomycin C was used to accomplish sufficient airway patency to relieve her symptoms. ETBT is a rare consequence of TB, which although has a low incidence in the United States, so physicians should have a high clinical suspicion based on the need for prompt intervention.

    Natalizumab (Tysabri®) is a leukocytes chemotaxis inhibitor that decreases the leukocytes passage through the hematoencephalic barrier and it is currently used in relapsing-remitting forms of multiple sclerosis (MS). We present a patient with allergic rhinoconjunctivitis diagnosed with MS who started treatment with natalizumab. She began to show mild asthmatic symptoms until she needed admission to the hospital due to respiratory insufficiency. Blood tests showed peripheral eosinophilia and the thoracic computed tomography scan demonstrated pulmonary infiltrates. The bronchoscopy with the bronchoalveolar lavage resulted in eosinophilic alveolitis. No evidence of bacterial, fungal and parasitic infection, connective tissue disease, or vasculitis were observed. After discontinuation of natalizumab, the patient improved without other treatments. As MS is a prevalent disease and the use of natalizumab is increasing, we consider important to point out that this drug can be associated with pulmonary eosinophilia, especially in patients with allergic rhinoconjunctivitis or asthma.

    2006-01-01

    Abstract:Thoracic endometriosis is a rare disorder. It can be divided into pleural and pulmonary parenchymal endometriosis according to the site of the lesion. In this article 3 typical cases of thoracic endometriosis (case 1 is pleural endometriosis, case 2 and 3 are pulmonary parenchymal endometriosis) were described, and the various presentations, pathogenesis, diagnosis, and therapies of thoracic endometriosis were reviewed. The pathogenesis of thoracic endometriosis has not been established clearly yet. Recurrent right-sided pneumothorax or hemoptysis that occurs within days of the onset of menstruation is the most common manifestation. The correlation between the patient's symptoms and menses is essential to establish the diagnosis. Radiographic studies, bronchoscopy, and thoracoscopy may support the diagnosis. Pathologic evidence is not present universally. Therapeutic interventions include medical and surgical options, which should be individualized for each patient.

    We present a 22-year-old woman with Kartagener syndrome and scoliosis who died 112 days after single lung transplant. The classic thoracic involvement of situs inversus totalis and the asymmetric arrangement of the thoracic vascular structures might be a pitfall for surgeon. Anatomic obstacles have forced the surgeon to perform a single transplant. The period of primary graft dysfunction in a single transplanted lung patient was a challenge; supporting the patient with a high flow and long period of extracorporeal membrane oxygenation might lead to a vanishing bronchus. Immotile cilia, a feature of Kartagener syndrome, were another challenge and patient needed several daily aspiration bronchoscopies. Vanishing bronchus is a gradual process with high mortality rates; commonly, stenosis is at the non anastomotic bronchial tree because of insufficient nourishment of the bronchial cartilages. Several repeat bronchoscopic balloon dilatations accompanied with medical treatment were unsuccessful.

    Full Text Available In patients with chronic respiratory diseases that last since the early childhood, primary ciliary dyskinesia (PCD needs to be considered. Four patients reviewed in this paper were with typical disease history and clinical picture, as well as clear ciliary axonema damage. Complete examination was performed in all the patients, including bronchoscopy with bronchography, and the examination of the biopsy samples of respiratory airways’ mucous membrane, obtained by transmission electron microscope (TEM. In two of the patients spermatozoa were also examined by TEM. Large anatomic deffects of airways were found in all the patients, but pulmonary function was normal (except in one case, representing one of PCD’s significant characteristics. First two cases fulfilled the criteria for Kartagener’s syndrome, which was initially sufficient for the diagnosis of PCD.

    Full Text Available We present the results of a multicenter study of 445 patients with “proven” and “probable” invasive aspergillosis (EORTC/MSG, 2008. Invasive aspergillosis usually occurs in patients with hematological malignancies (88 %, main underlying diseases were acute myeloid and acute lymphoblastic leukemia. The risk factors: prolonged agranulocytosis (64 %, cytostatic chemotherapy (57 %, corticosteroid treatment (45 %, and allogeneic hematopoietic stem cells transplantation (29 %. The pathogens – A. fumigatus (42 %, A. niger (33 %, and A. flavus (21 %. The main site of infection were lungs (86 %. 12 week overall survival was 83 %. Bronchoscopy use for the early diagnosis (p = 0.01, adequatetherapy with voriconazole (p = 0.002 and secondary antifungal prophylaxis (p = 0.0003 were positive prognostic factors for survival of patients with invasive aspergillosis.

    The nasogastric tube (NGT) has become a frequently used device to alleviate gastrointestinal symptoms. Nasogastric tube syndrome (NTS) is an uncommon but potentially life-threatening complication of an indwelling NGT. NTS is characterized by acute upper airway obstruction due to bilateral vocal cord paralysis. We report a case of a 76-year-old man with NTS, induced by an indwelling long intestinal tube. He was admitted to our hospital for treatment of sigmoid colon cancer. He underwent sigmoidectomy to release a bowel obstruction, and had a long intestinal tube inserted to decompress the intestinal tract. He presented acute dyspnea following prolonged intestinal intubation, and bronchoscopy showed bilateral vocal cord paralysis. The NGT was removed immediately, and tracheotomy was performed. The patient was finally discharged in a fully recovered state. NTS be considered in patients complaining of acute upper airway obstruction, not only with a NGT inserted but also with a long intestinal tube.

    2014-01-01

    Full Text Available A 44 year old male former smoker from Ecuador presented with productive cough for 3 weeks, positive tuberculin skin test, 40 lbs weight loss and right lower lobe collapse. He denied wheezing or hemoptysis. He was treated with antibiotics and ruled out for tuberculosis with negative sputum smear. Bronchoscopy showed an endobronchial lesion at the distal end of bronchus intermedius as cause of the collapse. Endobronchial biopsy of the lesion revealed an endobronchial leiomyoma, a rare cause of endobronchial tumor. The patient underwent bilobectomy as definite therapy for the leiomyoma due to its large size and possible extra-luminal extension, which made it not amenable to bronchoscopic resection or bronchoplasty. Differential diagnoses of endobronchial lesions are discussed along with clinical, radiographic, pathologic characteristics and various treatment modalities for endobronchial leiomyomas.

    2007-01-01

    Full Text Available We report a case of an elderly woman who developed a severe, chronic pulmonary reaction to nitrofurantoin therapy that she had taken continuously for three years to prevent urinary tract infections. The patient was taking no other drug known to cause lung disease but the diagnosis was delayed by failure to recognize the association between nitrofurantoin and adverse drug reactions affecting the lung. When originally seen, the patient was unable to care for herself due to dyspnea. Bronchoscopy with biopsy ruled out other causes of her pulmonary disease. Immediate withdrawal of nitrofurantoin led to substantial, sustained improvement and disappearance of symptoms over several months without administration of corticosteroids. Nitrofurantoin toxicity should always be considered in any person taking that drug who develops bilateral infiltrates.

    Full Text Available A young house wife presented with low grade fever, cough, haemoptysis and SOB of unknown aetiology for 40 days duration. Respiratory system examination revealed diffuse crepts and rhonchi. Other organ system examination did not reveal any abnormality. X-ray chest PA view and CT thorax showed diffuse bilateral necrotising nodular lesions of various sizes with small pleural effusion. She also had low resting oxygen saturation with falling haematocrit. Her Serum was week positive for p-ANCA and negative for MPO-ANCA. Bronchoscopy revealed continuous bloody aspirates. We could not isolate any organisms in any of the specimens from her and she was unresponsive to any of the antibiotics either. Based on the clinical, laboratory data, radiological features and positive outcome to pulse therapy of methylprednisolone and cyclophosphamide, she was diagnosed as a case of IPIPC.

    Miro, L

    After an analysis of the complex interweaving reactions of laser on biological materials, the laser applications in medicine and surgery are reviewed by the author. In ophthalmology its use is regular but not yet optimal. In otological applications the first results are good. In dermatology favorable results are obtained but the absence of special device had stopped his development. In surgery and endoscopy the best wave length must be chosen in reference to their hemostatic action and cutting, nevertheless in gastroscopy and bronchoscopy the laser seems to bring new therapeutic solutions. In odontology the pulsed lasers are dangerous for therapy but the holographic technique is a fertile research area. The author conclude to the necessary development of researches on the fundamental problems set by the biomedical applications of lasers.

  13. The Use of Extracorporeal Membrane Oxygenation in the Surgical Repair of Bronchial Rupture

    2016-02-01

    Full Text Available Extracorporeal membrane oxygenation (ECMO has been used successfully in critically ill patients with traumatic lung injury and offers an additional treatment modality. ECMO is mainly used as a bridge treatment to delayed surgical management; however, only a few case reports have presented the successful application of ECMO as intraoperative support during the surgical repair of traumatic bronchial injury. A 38-year-old man visited our hospital after a blunt chest trauma. His chest imaging showed hemopneumothorax in the left hemithorax and a finding suspicious for left main bronchus rupture. Bronchoscopy was performed and confirmed a tear in the left main bronchus and a congenital tracheal bronchus. We decided to provide venovenous ECMO support during surgery for bronchial repair. We successfully performed main bronchial repair in this traumatic patient with a congenital tracheal bronchus. We suggest that venovenous ECMO offers a good option for the treatment of bronchial rupture when adequate ventilation is not possible.

    Full Text Available The mortality rate for respiratory failure resulting from obesity hypoventilation syndrome is high if it requires ventilator management. We describe a case of severe acute respiratory failure resulting from obesity hypoventilation syndrome (BMI, 60.2 kg/m2 successfully treated with venovenous extracorporeal membrane oxygenation (VV-ECMO. During ECMO management, a mucus plug was removed by bronchoscopy daily and 18 L of water was removed using diuretics, resulting in weight loss of 24 kg. The patient was weaned from ECMO on day 5, extubated on day 16, and discharged on day 21. The fundamental treatment for obesity hypoventilation syndrome in morbidly obese patients is weight loss. VV-ECMO can be used for respiratory support until weight loss has been achieved.

    The prognosis of bronchogenic carcinoma depends on its histology and the time of its first diagnosis. The 5-year-survival rate after radiation treatment is 3-10%. It is much better for tumors detected and operated in an early stage, averaging 21%. The roentgenomorphology of central and peripheral bronchogenic carcinoma and the differential diagnosis is demonstrated on a selected group of 300 patients seen in the "Klinik und Poliklinik für Radiologie" in Munich between 1975 and 1979. In conclusion we think it not justified to hesitate performing bronchoscopy and/or percutaneous needle aspiration lung biopsy in cases of unclear peripheral or central pulmonary shadows, considering the low risks of the two procedures.

    2014-01-01

    Full Text Available Context: There are no established guidelines for the proper treatment of patients with bronchopleural fistulas (BPFs. Apart from attempts to close the fistula, emphasis of treatment and management is placed on preventive measures, early administration of antibiotics, drainage of the empyema and aggressive nutritional and rehabilitative support. Case Report: A 53-year-old male presented with nausea, vomiting, and dry cough with eventual respiratory failure. He was found to have an empyema of the left hemithorax which was managed with thoracostomy drainage and antibiotics. However, he had persistent air leak through the chest tube due to a BPF. Bronchoscopy failed to localize the involved segment. Application of fibrin glue through the chest tube succeeded in completely sealing the leak. Conclusion: To our knowledge, this is the first case report in which fibrin glue was successfully used intrapleurally to close a BPF related to an empyema.

    Introduction: Spontaneous pneumomediastinum, pneumothorax, and subcutaneous emphysema are rare, but serious complications of inflammatory myopathies and occur more commonly in DM than PM. complications of dermatomyositis (DM) and polymyositis (PM), both of which can be fatal. Case Report: A 20-year-old woman was admitted with neck pain, dyspnea, cough, and fever. She had been diagnosed with dermatomyositis 21 months prior. A thorax computed tomography (CT) scan revealed ground glass opacities in her lungs, pneumomediastinum, pneumothorax, and subcutaneous emphysema. Despite intensive immunosuppressive therapy, clinical deterioration and radiological progression were observed, ultimately the patient died. Conclusion: During the care for a patient with dermatomyositis, the otorhinolaryngologist should be cautious of rapidly progressive and fatal neck subcutaneous emphysema. For a patient with dermatomyositis and with normal bronchoscopy and esophagoscopy, the main treatment is control of dermatomyositis with medical therapy. Therefore, a tracheostomy and/or mechanical ventilation may not be necessary.

    Full Text Available Cases of pulmonary aspergilloma without any predisposing factors are rarely reported. Clinical presentation varies from case to case. Here, we report a case of pulmonary aspergilloma in a 60-year-old male patient who was admitted to the Intensive Respiratory Care Unit with spontaneous pneumothorax. The patient had a history of dyspnea on exertion since 9 months and mild haemoptysis since the last 6 months. A computerised tomographic scan of the lungs showed a lesion in the left main bronchus along with obstructive emphysema of the right lung, moderate pneumothorax and mediastinal emphysema. Bronchoscopy was performed and the biopsy samples were processed for histopathological examination and culture on Sabouraud′s dextrose agar, which yielded growth of Aspergillus flavus. Repeat sputum samples also yielded the growth of A. flavus . The patient responded to intravenous liposomaamphotericin B and intercostal drainage.

    The results of comparative studies of autofluorescence and 5-ALA-induced fluorescence of protoporphyrin IX, used in the diagnostics of early cancer of larynx and bronchi, are presented. The autofluorescence and 5-ALA-induced fluorescence images of larynx and bronchial tissues are analysed during the endoscopic study. The method of local spectrophotometry is used to verify findings obtained from fluorescence images. It is shown that such a combined approach can be efficiently used to improve the diagnostics of precancer and early cancer, to detect a primary multiple tumours, as well as for the diagnostics of a residual tumour or an early recurrence after the endoscopic, surgery or X-ray treatment. The developed approach allows one to minimise the number of false-positive results and to reduce the number of biopsies, which are commonly used in the white-light bronchoscopy search for occult cancerous loci.

    Lung cancer with an estimated 342,000 deaths in 2008 (20% of total) is the most common cause of death from cancer, followed by colorectal cancer (12%), breast cancer (8%), and stomach cancer (7%) in Europe. In former smokers, the absolute lung cancer risk remains higher than in never-smokers; these data therefore call for effective secondary preventive measures for lung cancer in addition to smoking cessation programs. This review presents and discusses the most recent advances in the early detection and screening of lung cancer.An overview of randomized controlled computerized tomography-screening trials is given, and the role of bronchoscopy and new techniques is discussed. Finally, the approach of (noninvasive) biomarker testing in the blood, exhaled breath, sputum, and bronchoscopic specimen is reviewed.

    2015-01-01

    Full Text Available Epithelial-myoepithelial carcinomas are rare tumors that primarily originate in the salivary glands but have also been found in the tracheobronchial tree. We report the first case of epithelial-myoepithelial carcinoma associated with sarcoidosis. A 61 year old Hispanic man presented with altered mental status and hypercalcemia. Imaging revealed diffuse intra-thoracic and intra-abdominal lymphadenopathy. A diagnostic bronchoscopy was performed where an incidental tracheal nodule was discovered and biopsied. Pathology was consistent with epithelial-myoepithelial carcinoma. Lymph node biopsy demonstrated non-caseating granulomas consistent with sarcoidosis. Patient underwent tracheal resection of the primary tumor with primary tracheal reconstruction. Hypercalcemia subsequently normalized with clinical improvement. Repeat CT imaging demonstrated complete resolution of lymphadenopathy. Our findings are suggestive of a possible paraneoplastic sarcoid-like reaction to the epithelial-myoepithelial carcinoma with associated lymphadenopathy and symptomatic hypercalcemia.

    Full Text Available Typical carcinoid of the trachea presenting as an endoluminal polypoidal mass is a rare occurrence. Herein, we report a case of a 34-year-old female patient who presented with features of central airway obstruction. Flexible bronchoscopy demonstrated a large pedunculated growth arising from the lower end of the trachea near carina which was flopping in and out of the main tracheal lumen and the proximal right bronchus leading to dynamic airway obstruction. Successful electrosurgical excision (using a snare loop of the polypoidal growth was performed using the flexible bronchoscope itself. The patient had immediate relief of airway obstruction and histopathological examination of the polyp demonstrated features of typical carcinoid (WHO Grade I neuroendocrine tumor.

    Background Congenital vascular rings may often cause unexplained respiratory symptoms in infants and young children. Their diagnosis and treatment are often delayed. Few studies of vascular rings have been reported in China.The aim of this study was to describe the clinical presentation, diagnosis and surgical management of infants and children with congenital vascular rings.Methods Clinical histories, physical examinations, investigations, image studies and surgical interventions were retrospectively evaluated in 7 children (age range: 2 months- 4 years, mean 7 months) with congenital vascular rings.Chest radiography was performed in all patients. Echocardiography and computed tomography (CT) with 3-dimensional (3D) reconstructions were performed in 6 patients. Esophagography, cardiac catheterization and angiography, and bronchoscopy were performed in 1, 1 and 4 children, respectively.Results Six of the 7 patients had respiratory symptoms, including recurrent cough, stridor and wheeze. Age at onset of symptoms ranged from 1 month to 11 months. Chest X-ray showed nothing important on the vascular rings, besides bronchitis and pneumonia. Contrast-enhanced CT diagnosed vascular rings in 6 patients. Four patients had double aortic arches, two had balanced arches and two were right arch dominant. One patient had a right aortic arch with left ligament and 1 patient had a pulmonary artery sling. Echocardiography failed to diagnose vascular rings in 2 patients. The esophagogram of 1 patient showed esophageal compression. Bronchoscopy of 4 patients showed compression of the distal trachea. Five of the 7 patients underwent surgical division of the vascular rings. Surgical observation confirmed the CT findings in each patient.Conclusions Patients, especially infants or young children, with recurrent respiratory symptoms such as chronic cough, stridor and wheeze, should be examined for the possible presence of congenital vascular rings.Contrast-enhanced CT can clearly show

    Foreign body (FB) removal in our hospital was almost exclusively performed by surgeons through a rigid bronchoscope until the pulmonologists started getting involved in FB extraction. This study aimed to retrospectively review the results of 2 years of experience with 120 patients who presented or were referred to the Pulmonary Medicine Department, Ain Shams University Hospital in Cairo, Egypt, with clinical suspicion of FB aspiration during the period between December 2006 and December 2008. FBs were removed by either rigid and/or flexible bronchoscopy using either general or topical anesthesia. There were 54 male and 66 female patients with an age range between 3 months and 70 years and 68.5% of the patients were under the age of 10 years. Ninety patients (75%) presented with a definite history of FB aspiration, with a time interval between aspiration and presentation ranging between less than 6 hours and 12 months. The FB was visible on the chest x-ray in 42 cases. Aspirations were primarily into the right lung (53.2%). Seeds and scarf pins were the most common FB found, and were retrieved in 36 cases. Pulmonologists were successful in extracting 110 out of 111 (99.1%) bronchoscopically visualized FBs, and open thoracotomy was required in only 1 case for FB removal. In another 6 cases, only mucous plug was found to be the endogenous FB, whereas no FB could be found in 3 cases. No mortality or serious complications took place during or after the bronchoscopy. In conclusion, pulmonologists can extract FBs easily and safely either by using rigid and/or flexible bronchoscopes if they have the appropriate experience.

    2008-04-15

    Background: In Sweden, there are over 3000 new lung cancer cases every year. There are still numerous patients with undetermined lesions after routine diagnostic evaluation by clinical examination, chest radiography, computed tomography (CT) of the thorax, and bronchoscopy. An appropriate method for further diagnostic workup is therefore needed. Purpose: To evaluate the diagnostic value of the somatostatin analogue depreotide in patients with suspected lung cancer, and to determine in which clinical settings it would be beneficial to use 99mTc-depreotide scintigraphy. Material and Methods: We included 99 consecutive patients referred to our hospital with suspected lung cancer. A clinical examination, bronchoscopy, chest radiography, CT of the thorax and upper abdomen, and scintigraphy were done. Scintigraphy was performed after injection of 740 MBq 99mTc depreotide with tomographical imaging of the thorax and whole-body scanning. The diagnostic outcome of the scintigrams was compared to CT, using morphology or clinical outcome as the endpoint. Results: 99mTc-depreotide uptake was found in 62 out of 66 malignancies, including 57 of 58 primary lung cancer cases. Two cases of lung metastasis (one from a colon cancer and one from an adenoid cystic carcinoma originating in the palate) and one rib chondrosarcoma did not show depreotide uptake. There were 33 patients with benign lesions, of whom 16 displayed false-positive 99mTc-depreotide uptake, whereof 11 were pneumonias. Tc-99m-depreotide uptake was absent in 17 patients with benign lesions, including all 10 hamartomas. The sensitivity in detecting malignancy was 94%, and in detecting lung cancer 98%. The specificity was calculated based on two sets of data. When all cases were used, the specificity was 52%. If the 12 pneumonias are excluded, the specificity was 77%. Conclusion: 99mTc-depreotide scintigraphy has a high sensitivity in detecting lung cancer. The method is useful in decision-making with respect to

    Familiarity with prevailing pattern and variations in the bronchial tree is not only essential for the anatomist to explain bronchial variation in bronchial specimens, but also useful for guiding bronchoscopy and instructing pulmonary segmental resection. The purpose of this study was designed to demonstrate various branching patterns of left lung with 3D images, with special attention given to identify the major types at transverse thin-section CT. Two hundred and sixteen patients with routine thorax scans were enrolled. The images of bronchial tree, virtual bronchoscopy were reconstructed using post-processing technique of multi-detector row CT. We attempted to classify the segmental bronchi by interpreting the post-processing images, and identified them in transverse thin-section CT. Our results showed that the segmental bronchial ramifications of the left superior lobe were classified into three types mainly, i.e., common stem of apical and posterior segmental bronchi (64%, 138/216); trifurcation (23%, 50/216); common stem of apical and anterior segmental bronchi (10%, 22/216), and they could be identified at two typical sections of transverse thin-section CT. There were two major types in left basal segmental bronchi, i.e., bifurcation (75%, 163/216), trifurcation (18%, 39/216), and they could also be identified at two typical sections of transverse thin-section CT. In conclusion, our study have offered simplified branching patterns of bronchi and demonstrated various unusual bronchial branching patterns perfectly with 3D images, and have also revealed how to identify the main branching patterns in transverse thin-section CT.

    Full Text Available Right lung agenesis is a rare anomaly that can be isolated or accompanied by system anomalies such as cardiac, skeletal or urinary systems. Case 1, a four-month-old girl, was brought because of respiratory distress. Patient had polydactyly, syndactyly of right thumb, right mandibular hypoplasia and low-set dysmorphic ears. Lung x-ray and thorax computerized tomography (CT were consistent with right pulmonary agenesis and butterfly vertebra was evident in the 7th thoracic level. Thoracic CT angiography revealed narrowing of the left main bronchus and esophagus due to compression of aorta, left pulmonary artery and right atrium. In bronchoscopy, narrowing due to compression at the carina level was seen and right main bronchus was not seen. In abdominal ultrasonography, right kidney placement anomaly (pelvic ectopia was present and renal scintigraphy revealed fusion in both kidneys. With these findings, it was found that right pulmonary agenesis was accompanied by ipsilateral radial ray anomaly, renal anomaly, vertebral anomaly and hemifacial microsomia. Case 2, a fifteen-year-old male patient, was diagnosed as pulmonary agenesis via chest x-ray, pulmonary CT and bronchoscopy after a wheezing episode when he was 2 months old. Patient had no complaint except for exhaustion that is aggravated by exercise during last year. In physical examination, he had a mild scoliosis toward right, respiratory sounds were diminished on right hemithorax and heart sounds were heard on right side. Chest x-ray and thoracic CT were consistent with right lung agenesis. No abnormality was found in echocardiography and abdominal ultrasonography was normal. Accompanied cardiovascular anomalies, distortions of intrathoracic structures and recurrent infections are main factors that affect mortality and morbidity. Here, two cases with right lung agenesis, isolated and accompanied by multiple anomalies, were presented. (Jo­ur­nal of Cur­rent Pe­di­at­rics 2013; 11: 134-7

    Full Text Available Diffuse parenchyma lung disease (DPLD encompasses a hetero - geneous group of disorders, characterized by a spectrum of inflammatory and fibrotic changes affecting alveolar walls and air spaces. They comprise over 200 entities and include a wide spectrum of diseases, many uncommon and many of unknown etiology. The incidence and prevalence rates of DPLD have not been precisely estimated due to difficulties in ascertaining a specific diagnosis on a specific disease. MATERIAL & METHODS : Prospective observational study done on 20 adult patients with radiologically diffuse parenchymal lung disease admitted between January 2010 and May 2015 in Govt. General & Chest Hospital, Hyderabad were subjected for Transbronchial Lung Biopsy via flexible fibreoptic bronchoscopy, without fluoroscopic guidance. RESULTS : Out of 20 patients studied adequate lung tissue was obtained in 15 patients, yield of the procedure was 75%. Out of 15 patient’s histopathological diagnosis of chronic interstitial pneumonia is seen in 5 members, interstitial fibrosis is seen in 4 members, non caseating granulomas seen in 4 members, pulmonary alveolar protenosis was seen in 1 member and normal lung histopathology was seen in 1 members. Diagnostic yield of the procedure was 93.3% and overall diagnostic yield was 70%. Two patients developed post procedure pneumothorax. Both of them underwent closed - tube thoracostomy, lung expanded well and ICD was removed in 4 days. No significant bleeding was observed in any patient. No mortality was observed after the procedure . CONCLUSIONS : Transbronchial lung biopsy through flexible bronchoscopy is a simple, safe and effective procedure for the diagnosis of diffuse parenchymal lung diseases. Complications were observed in only few patients out of twenty, which were successfully managed with ICD.

    Full Text Available Background: Anthracosis is the black pigmentation of the mucosal lining of the tracheo-bronchial tree. The significance of this finding is not known and often ignored. The aim of the present study is to find the association of anthracosis with demographic variables, biomass fuel and occupational exposure, respiratory diseases, radiological pattern and functional morbidity. Materials and Methods: Enrolment of the subjects for the study was done at SMS hospital, Jaipur. Patients with anthracosis evident on bronchoscopy were included as the cases. Patients without anthracosis on bronchoscopy, matched according to age, gender and smoking habits, were included in the control group. Subjects in both the arms completed a questionnaire and also underwent computed tomography (CT of the chest and six minute walk test (6MWT. Results: Thirty cases and 53 controls were included in the study. The patients with anthracosis presented with symptoms ranging from cough (76.65%, hemoptysis (46.6%, fever (26.6%, dyspnea (90% and malaise (73.3%. Biomass fuel exposure for the cases was 35.13 ± 55.86 hours in a year and for the controls was 28.15 ± 40.09 hours in a year (P > 0.05. Stone mining was significantly associated with anthracosis (P < 0.05. CT chest revealed fibrosis (43.3%, consolidation (33.3%, cavitation (16.6% and mass (46.6% in the cases. Sixty percent of cases and 15% of controls were diagnosed to have either old or active pulmonary tuberculosis (P < 0.05. Conclusions: Anthracosis is associated with pulmonary tuberculosis. Biomass exposure is not significantly associated with anthracosis. Post tubercular fibrosis is more common on CT chest of patients with anthracosis.

    The objective of this study was to determine the effect of previous aerosolized pentamidine therapy on diagnosis and presentation of Pneumocystis carinii pneumonia. This was a retrospective study of fifty-two consecutive patients with P. carinii pneumonia and underlying infection with the human immunodeficiency virus (HIV) who had bronchoscopy. Twenty-one patients who were on aerosolized pentamidine therapy served as the study group. Thirty-one patients who had not received the drug served as the control group. The yield of bronchoalveolar lavage for P. carinii pneumonia was 62% for the study group and 100% for the control group (P less than 0.05). This lower yield was significant for the subset of patients having their first episode of P. carinii pneumonia. The yield of transbronchial biopsy was similar for both groups of patients (81% compared with 84%). The yield of bronchoscopy was not influenced by use of zidovudine. Review of lavage specimen slides suggested that there may be fewer organisms present in patients receiving aerosolized pentamidine. An atypical roentgenographic presentation of upper lobe predominant infiltrates was seen in 38% of the study patients and 7% of the control patients. In addition, pneumothoraces and cystic changes were also frequently seen in the study patients. Gallium scans, when done, were also atypical in the study group. Markers of the severity of disease, however, were similar in both groups. The yield of bronchoalveolar lavage for P. carinii pneumonia in HIV-infected patients is lower in patients receiving aerosolized pentamidine. Unusual roentgenographic presentations and atypical gallium scans are also found in this setting.

    The pneumolysin (ply) gene is widely used as a target in PCR assays for Streptococcus pneumoniae in respiratory secretions. However, false-positive results with conventional ply-based PCR have been reported. The aim here was to study the performance of a quantitative ply-based PCR for the identification of pneumococcal lower respiratory tract infection (LRTI). In a prospective study, fibreoptic bronchoscopy was performed in 156 hospitalized adult patients with LRTI and 31 controls who underwent bronchoscopy because of suspicion of malignancy. Among the LRTI patients and controls, the quantitative ply-based PCR applied to bronchoalveolar lavage (BAL) fluid was positive at >or=10(3) genome copies/mL in 61% and 71% of the subjects, at >or=10(5) genome copies/mL in 40% and 58% of the subjects, and at >or=10(7) genome copies/mL in 15% and 3.2% of the subjects, respectively. Using BAL fluid culture, blood culture, and/or a urinary antigen test, S. pneumoniae was identified in 19 LRTI patients. As compared with these diagnostic methods used in combination, quantitative ply-based PCR showed sensitivities and specificities of 89% and 43% at a cut-off of 10(3) genome copies/mL, of 84% and 66% at a cut-off of 10(5) genome copies/mL, and of 53% and 90% at a cut-off of 10(7) genome copies/mL, respectively. In conclusion, a high cut-off with the quantitative ply-based PCR was required to reach acceptable specificity. However, as a high cut-off resulted in low sensitivity, quantitative ply-based PCR does not appear to be clinically useful. Quantitative PCR methods for S. pneumoniae using alternative gene targets should be evaluated.

    Full Text Available A estenose idiopática de traquéia é incomum. Relatam-se quatro casos com quadro clínico semelhante: história de tratamento de broncoespasmo sem resultado e diagnóstico por broncoscopia. O tratamento em três pacientes foi dilatação e corticóide sistêmico; em um realizou-se traqueoplastia. No quarto, a estenose era mais extensa (2 cm com redução da luz de 70%, sem possibilidade de dilatação. Realizou-se ressecção laringo-traqueal. Todos apresentaram boa evolução. A estenose idiopática de traquéia deve ser cogitada em casos de "bronquite" mal resolvida com tratamentos convencionais. A broncoscopia e a dilatação têm apresentado bons resultados. Eventualmente, torna-se necessária ressecção laringo-traqueal.Idiopathic tracheal stenosis is uncommon. Herein, we report four cases, all presenting a similar clinical profile: diagnosed through bronchoscopy and having a history of being treated unsuccessfully for bronchospasm. Three of the patients were treated with dilatation and an oral corticosteroid. One of those three underwent tracheoplasty. In the remaining patient, the stenosis was more extensive (2 cm, with a 70% reduction in the size of the lumen, and dilatation was not an option. Therefore, that patient underwent laryngotracheal resection. In all four patients, the evolution was favorable. Idiopathic tracheal stenosis should be contemplated in cases of ‘bronchitis’ that are not resolved using conventional treatments. Bronchoscopy and dilatation have provided satisfactory results. Occasionally, laryngotracheal reconstruction is necessary.

    We submit the case of a child afflicted with a mucoepidermoid bronchial tumor. The patient is a boy, aged seven, who after undergoing antibiotic treatment for six weeks because of a fever and atelectasia-condensation in the right lower lobe showed no signs of clinical improvement and was sent to our department to undergo further study and treatment. A bronchoscopy performed shows a polypoid mass that partially blocks the main bronchial tube a few milimiters under the access to the right upper lobe. A biopsy is carried out and the anatomopathological test shows there is a low degree epidermoid carcinoma. We decide to perform a lobectomy which for the tumor location and the lung condition has to be medium and lower right. We proceed to remove the adenopaty of hilium not affected by the tumor. The postoperative period develops without incidents. A check-up bronchoscopy performed three months later shows two polypoid masses in the right bronchial tube which, once a biopsy is performed, proved to be granulation tissue. Twelve months after undergoing surgery, the patient's condition is good, there is no evidence of tumor relapse and the breathing capacity is adequate, though there is an obstructive restrictive pattern in the espirometry. Even taking into consideration that lung tumors are extremely unusual, the epidermoid carcinoma is the one which most frequently occurs. The tumor's low malignancy is a sign that points to a good prognosis. Performing conservative surgery by means of bronchoplasty should be taken into account so as to keep the sequelae on the lung condition to a minimum, even though in this case the tumor location made it impossible.

    ABSTRACT Objective: Conventional bronchoscopy has a low diagnostic yield for peripheral pulmonary lesions. Radial-probe EBUS employs a rotating ultrasound transducer at the end of a probe that is passed through the working channel of the bronchoscope. Radial-probe EBUS facilitates the localization of peripheral pulmonary nodules, thus increasing the diagnostic yield. The objective of this study was to present our initial experience using radial-probe EBUS in the diagnosis of peripheral pulmonary lesions at a tertiary hospital. Methods: We conducted a retrospective analysis of 54 patients who underwent radial-probe EBUS-guided bronchoscopy for the investigation of pulmonary nodules or masses between February of 2012 and September of 2013. Radial-probe EBUS was performed with a flexible 20-MHz probe, which was passed through the working channel of the bronchoscope and advanced through the bronchus to the target lesion. For localization of the lesion and for collection procedures (bronchial brushing, transbronchial needle aspiration, and transbronchial biopsy), we used fluoroscopy. Results: Radial-probe EBUS identified 39 nodules (mean diameter, 1.9 ∓ 0.7 cm) and 19 masses (mean diameter, 4.1 ∓ 0.9 cm). The overall sensitivity of the method was 66.7% (79.5% and 25.0%, respectively, for lesions that were visible and not visible by radial-probe EBUS). Among the lesions that were visible by radial-probe EBUS, the sensitivity was 91.7% for masses and 74.1% for nodules. The complications were pneumothorax (in 3.7%) and bronchial bleeding, which was controlled bronchoscopically (in 9.3%). Conclusions: Radial-probe EBUS shows a good safety profile, a low complication rate, and high sensitivity for the diagnosis of peripheral pulmonary lesions. PMID:27832231

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    Full Text Available Objectives: Ever since the discovery of Mycobacterium tuberculosis in 1882, many diagnostic methods have been developed. However "The gold standard" for the diagnosis of tuberculosis (TB is still the demonstration of acid fast Bacilli (AFB by microscopic examination of smear or bacteriological confirmation by culture method. Materials and Methods: In suspected 75 patients with active pulmonary TB, the materials obtained bronchoscopically, were bronchoalveolar lavage (BAL, bronchial brushings, bronchial washings and post bronchoscopic sputum. Four smears were made from each of the specimen. Fluorescent Staining, Ziehl–Neelsen (ZN, Pap and May Grunwald-Giemsa (MGG stains were carried out for cytological examination. Results: Fluorescent stain yielded maximum AFB positivity in all the methods, that is 36 (48% in post fibre-optic bronchoscopy (FOB sputum and 19 (25.33% by fluorescence microscopy in both bronchial brushings and bronchial washings. Maximum yield of AFB with ZN staining 12 (16% was equal to the post FOB sputum and bronchial brushings samples. It was followed by 6 cases (8% in BAL and 4 (5.3% in bronchial washings. The cytological examination was suggestive of TB in only 8 (10.66% cases in bronchial washings and 6 (8% cases in post FOB collection. It was equal in BAL and Bronchial brushings each that is 5 (6.67%. Conclusion: Bronchoscopy is a useful diagnostic tool and fluorescent microscopy is more sensitive than ZN and cytology. On X-ray examination, other diseases like malignancy or fungus can also mimick TB. So apart from ZN staining or fluorescence microscopy, Pap and MGG stain will be worthwhile to identify other microorganisms.

    Full Text Available The present study was designed to compare induction and recovery characteristics of sevoflurane and halothane for rigid bronchoscopy for removal of foreign bodies in tracheobronchial tree in children. Forty four children (age 1-4 years were allocated randomly to two groups to receive either halothane (group H; n=22 or sevoflurane (group S; n=22 in oxygen. A graded inhalation technique was used with maximum inspiratory concentration of 5% for halothane and 8% for sevoflurane. Time for loss of consciousness and induction time in group H and group S were 2.3+/-0.4 min vs 2.2+/-0.4 min (p>0.05 and 4.6+/-0.7 min vs 4.9+/-0.6 min (p>0.05 respectively. Intubation conditions with rigid bronchoscope were similar in both groups. Fewer children in group H had vocal cord movements as compared to group S on laryngoscopy (3 vs 8, p>0.05. Six children in group H and two children in group S had disturbances of cardiac rhythm (p>0.05. Emergence time was significantly shorter in group S as compared to group H (group H - 29.6+/-10.7 min vs group S- 12.3+/-7.6 min, p<0.05. Modified Aldrete′s score of 8 was achieved significantly faster in group S as compared to group H (group H - 33.8+/-9.3 min vs group S- 17.3+/-6.8 min, p<0.05. Adverse events during induction and recovery were comparable between the two groups except for significantly high incidence of excitement in group S. In conclusion, halothane is as suitable as sevoflurane for children undergoing rigid bronchoscopy for airway foreign body retrieval, but sevoflurane has a quicker recovery.

Malignant degeneration into squamous cell carcinoma is quite common, although curative approaches vary a lot in modern literature.Case report: We report a case of a 66-year-old male patient with the coexistence of multiple squamous cell papilloma and carcinoma in the upper trachea with severe airway obstruction that was diagnosed through bronchoscopy and treated by performing an urgent tracheostomy, followed by concurrent chemotherapy and radiotherapy. There was no evidence of recurrence after a 12-month follow-up period.Conclusion: This study underlines the diagnostic and therapeutic value of bronchoscopy as well as multimodality palliative treatment in such cases. To the best of our knowledge, this is the first study to describe an immediate treatment protocol with tracheostomy and concurrent chemotherapy/radiotherapy in a patient with squamous cell tracheal papilloma and carcinoma

    Full Text Available Background: Auto-fluorescence bronchoscopy (AFB has been used for the identification and localization of intra-epithelial pre-neoplastic and neoplastic lesions within the bronchus. Objectives: To determine the applicability of AFB for the detection and localization of precancerous and cancerous lesions, in addition to analyzing the morphologic presentation, their association to histological type and the variation between genders. Methods: A five-year study involving 4983 patients, who underwent routine bronchoscopy [B] examination in a local tertiary teaching hospital, was done. The B examination was performed under intratracheal lidocaine, and samples were obtained using suitable approach. One thousand four hundred and eighty-five pathologically confirmed lung cancer patients were included in the study. The following parameters were studied: Morphological presentation, biopsy sites, histology. Differences between the groups were analyzed using Chi square test. Result: One thousand four hundred and eighty-five patients who had hyperplasia or neoplastic lesions were further confirmed as lung cancer pathologically. Lung cancer was more commonly found in the right lung (51.58% vs. 42.82%. The lesion occurred more frequently in the upper lobe than the lower lobe (44.17% vs. 22.42%. Male patients with squamous cell carcinoma showed upper lobe involvement more commonly, while the left main bronchus was more commonly involved in female patients. Adenocarcinoma mostly involved lesion of the upper lobe. Squamous cell carcinoma and small cell carcinoma were the major proliferative types (80.15% and 76.16% respectively. Conclusion: AFB is efficient in the detection of pre-invasive and invasive lung lesions. The morphological presentation is associated to the histological type. There is variation in the presentation and histology of cancerous lung lesions between genders.

    Objective To explore the diagnostic value of multidetector spiral CT (MDCT) for foreign bodies in trachea and bronchus of children. Methods The clinical and MDCT manifestations of 97 children with highly suspected tracheobronchial foreign body were analyzed retrospectively. MDCT scan and bronchoscopy were performed in all the patients, and the post - processing reconstruction included multiple planar reconstruction ( MPR ), CT virtual bronchoscopy (CTVB), shaded surface display (SSD) and minimum intensity projection (MinlP).Results The clinical symptoms of tracheobronchial foreign bodies in children were generally atypical, and the common symptoms were various degrees of wheezing, coughing and recurrent lung infection. Of all the 97 cases, the foreign bodies were mainly opaque plant ones,and mostly were located in the bronchus lobaris and below the segmental bronchus,the left or right main bronchus. In 89 eases, foreign bodies were found directly by MDCT reconstruction, and the complications such as obstructive pneumonia, emphysema, atelectasis and mediastinal emphysema caused by foreign bodies were also shown. In 4 cases, MDCT only showed emphysema on one side and patchy pulmonary inflammation, while the foreign bodies which were not found by MDCT were removed by bronchoscopy. In another 4 cases, foreign bodies in the bronchial lumen showed on MDCT disappeared under bronchoscopy, among which two turned to be thick sputum. After anti - inflammatory treatment, lung inflammation and clinical symptoms disappeared in these patients. Bronchoscopy was performed under the guidance of CT imaging results, and the foreign bodies were removed successfully in 93 cases. The accuracy of MDCT in the diagnosis of tracheobronchial foreign body in children was 95.9%. Conclusions MDCT has great value in the diagnosis of tracheobronchial foreign body in children, but the clinical history and physical signs of the patients should also be considered.%目的 探讨多排螺旋CT(MDCT)

    years of age undergoing bronchoscopy due to clinical suspicion of foreign body aspiration at the State University at Campinas Hospital das Clinicas from January of 2000 to December of 2005. RESULTS: The sample consisted of 69 patients, ranging in age from 8 months to 12 years/7 months (75.4% under 3 years of age, 62.3% of whom were male. The principal complaint was sudden-onset cough (75.4%, auscultation was abnormal in 74%, and dyspnea was observed in 29%. Radiological abnormalities were seen in 88% of the cases. Aspirations were primarily into the right lung (54.8%, and 30.7% of the foreign bodies were of vegetal origin (principally beans and peanuts. In the follow-up period, 29% presented complications (most commonly pneumonia, which were found to be associated with longer aspiration time (p = 0.03. Mechanical ventilation was required in 7 children (10.1%, and multiple bronchoscopies were performed in 5 (7.2%. CONCLUSION: A history of sudden-onset choking and cough, plus abnormal auscultation and radiological findings, characterizes the profile of foreign body aspiration. In such cases, bronchoscopy is indicated. Longer aspiration time translates to a higher the risk of complications. The high prevalence of foreign bodies of vegetal origin underscores the relevance of prevention programs aimed at children younger than 3 years of age.

    Purpose: To evaluate the role of chest radiography, single-slice CT and 16-row MDCT in the direct evidence of tracheobronchial injuries. Methods: Patients with acute tracheobronchial injury were identified from the registry of our level 1 trauma center during a 5-year period ending July 2005. Findings at chest radiograph and CT were compared to those shown at bronchoscopy. Results: Eighteen patients with tracheobronchial injury - three patients with cervical trachea injury, eight with thoracic trachea injury and seven with bronchial injury - were identified. Twelve patients had a blunt trauma (67%), six patients had a penetrating (iatrogenic) injury (33%). Chest radiograph directly identified the site of tracheal injury in four cases, showing overdistension of the endotracheal cuff in three cases and displacement of the endotracheal tube in one case. At the level of the bronchi, chest radiograph demonstrated only one injury. CT directly identified the site of tracheal injury in all the cases showing the overdistension of the endotracheal cuff at the level of the thoracic trachea (three cases), posterior herniation of the endotracheal cuff at the thoracic trachea (three cases), lateral endotracheal cuff herniation at the thoracic trachea (one case), tracheal wall discontinuity at the cervical (one case) and at the thoracic trachea (one case) and displacement of endotracheal tube at the cervical trachea (two cases). At the level of the bronchi, CT correctly showed the site of injury in six case including: discontinuity of the left main bronchial wall (two cases), the 'fallen lung' sign (one case), right main bronchial wall enlargement (one case), discontinuity of the right middle bronchial wall (two cases). In one case, CT showed just direct 'air leak' at the level of the carina suggesting main bronchus injury. This finding was confirmed by bronchoscopy. Conclusion: Chest radiograph was helpful for the assessment of iatrogenic tracheal injuries

    In the present work 92 patients were studied all of whom had inhaled a foreign body (FB) into one of the tracheobronchial branch. The following factors were evaluated: sex, age, nature of the FB, localization in the respiratory tree, clinical symptoms, radiological findings, time lapse between diagnosis and removal. The peak incidence (61.9%) was in children under 3 years of age with a male-female ratio of 2:1. The most frequently inhaled FBs were of organic nature (31.5%); of these 58.6% were peanuts. The time lapse between inhalation and removal of the FB was as follows: in 20.5% the object was removed within 24 hours; in 66.4% within one week; in 12% in more than a week; and in 1.1% it took more than 8 weeks. In 53.2% of the cases the right bronchial branches were involved while in 28.2% the left side was affected. The most frequent symptoms were coughing (73.9%), wheezing (69.5%), dyspnea (51%) and fever (17.3%). Radiography detected the FB in only 7 cases (8.7%); in the remaining cases only indirect signs of the FB could be found: atelectasia (11.9%), emphysema (19.5%), cardio-mediastinic shift controlateral to the FB (10.8%). As regards complications, only 6 patients showed signs of slight endobronchial bleeding, 2 cases showed a pneumothorax and one other patient required a tracheotomy because of the particular shape of the FB which proved unable to pass backward through the glottis. In all cases the FB was removed using stiff bronchoscopy under either local or general anesthesia. The authors feel that, even if no clinical signs are found and radiography proves negative, one must always consider the possibility of a FB in the tracheal-bronchial branches, particularly in patients within the age range most at risk (under 3 years) and in those having a highly suspicious clinical history. In addition, the authors assert that the use of corticosteroids before and after the bronchoscopy markedly decreases the incidence of post-operative subglottic edema which

    Virtual endoscopy of the upper, central and peripheral airways (virtual laryngoscopy or virtual bronchoscopy) produces endoluminal images similar to those of fiberoptic endoscopy. In particular, virtual endoscopy is useful for the assessment of endoluminal tumor extent and tracheobronchial stenosis. Especially since the introduction of multirow detector CT, high-resolution virtual-endoscopic images of the airways can be reconstructed. Either surface rendering or volume rendering can be used for realistic depiction of the airways. Semitransparent color-coded volume rendering is advantageous, because adjacent structures can be displayed in addition to endoluminal views. A major advantage of virtual endoscopy over fiberoptic endoscopy is its non-invasiveness. With virtual endoscopy, even a high-grade stenosis is passable, enabling evaluation of the distal airways. Disadvantages are its inability to depict mucosal color and to perform therapeutic maneuvers. In comparison to other CT display modes, virtual endoscopy allows a more realistic assessment of tracheobronchial stenosis than axial CT slices and multiplanar reformats. Virtual endoscopy of the airways can be used complementary to fiberoptic endoscopy before tracheotomy, stent implantation or lung resection and for post-operative follow-up. In the future, virtual airway endoscopy will be increasingly applied for interactive virtual reality guidance of airway procedures such as bronchoscopy and surgery. (orig.)

    The report is a retrospective review of 238 benign tracheal stenoses of various etiologies treated between 1995 and 2008. To show that urgent segmental resection has complication rates similar to elective resection and, therefore, preoperative dilation is not necessary, we analysed records of patients who underwent either standard segmental resections with anterolateral mediastinal tracheal mobilization, single-suture anastomosis and neck flexion; or insertion of T-tube with oval-shaped horizontal arm. Primary segmental resection was performed in 164 patients (68.9%), including 14 cases with concomitant tracheo-esophageal fistula (TEF). T-tube as an initial treatment suited 74 (31.1%) patients. We encountered two partial and one complete anastomotic disruptions following subglottic resections treated by T-tube insertion and costal cartilage tracheoplasty or permanent tracheostomy. Restenosis rate in segmental resection was 3.1%. No difference in complication rate between urgent and elective segmental resections was experienced. We treated a small number of patients by endotracheal stent insertion but the results were discouraging. Urgent segmental resection without prior rigid bronchoscopy dilation is our strategy of choice whenever possible. As an alternative to dilation we prefer temporary insertion of modified T-tube. Stand-alone endoluminal dilation and stenting has yet to prove its safety and long-term efficacy.

    A twenty eight-year-old male presented with a two week history of dyspnea, cough, hemoptysis, chest pain, and fever 38-39°C. He also complained of loss of appetite, general weakness and left leg pain for two months preceding admission. He was referred with suspicion of lung tumor to our institution. Chest X-ray showed almost total atelectasis of the right lung with compensatory overinflation of the contralateral lung. Using computed tomography (CT), a lesion of diameter of 19.3 x 14.1 x 19.1 cm in the right lung, pleuritis, Th3 osteolysis, and compensatory overinflation of the left lung was seen. Bronchoscopy revealed a total obstruction of the right main bronchus due to submucosal infiltration and compression of the right main bronchus with negative histology of bronchial biopsy specimens. Transthoracic fine needle aspiration revealed celullae suspectae probabiliter neoplasmaticae suggesting tumor fusocellularis. USG of the abdomen revealed liver with numerous heterogeneous, solid areas hypo- and hyperechogenic, some of them with features of liquid or the disintegration up to diameter of 74 mm. Subsequent fine needle aspirations of the thorax and liver revealed fibrolamellar hepatocarcinoma and carcinoma adenoides of the lung. Patient underwent chemotherapy with 5-FU/DDP/VCR with no response. This report presents a case of a rare lung metastasis from FL-HCC.

    Full Text Available Abstract Introduction This case report describes an extremely rare combination of paroxysmal autonomic instability with dystonia and tuberculous meningitis. Paroxysmal autonomic instability with dystonia is normally associated with severe traumatic brain injury. Case presentation A 69-year-old man of Indonesian descent was initially suspected of having a community-acquired pneumonia, which was seen on chest X-ray and computed tomography of the chest. However, a bronchoscopy showed no abnormalities. He was treated with amoxicillin-clavulanic acid in combination with ciprofloxacin. However, nine days after admission he was disorientated and complained of headache. Neurological examination revealed no further abnormalities. A lumbar puncture revealed no evidence of meningitis. He was then transferred to our hospital. At that time, initial cultures of bronchial fluid for Mycobacterium tuberculosis turned positive, as well as polymerase chain reaction for Mycobacterium tuberculosis. Later, during his stay in our intensive care unit, he developed periods with hypertension, sinus tachycardia, excessive transpiration, decreased oxygen saturation with tachypnea, pink foamy sputum, and high fever. This constellation of symptoms was accompanied by dystonia in the first days. These episodes lasted approximately 30 minutes and improved after administration of morphine, benzodiazepines or clonidine. Magnetic resonance imaging showed an abnormal signal in the region of the hippocampus, thalamus and the anterior parts of the lentiform nucleus and caudate nucleus. Conclusions In patients with (tuberculous meningitis and episodes of extreme hypertension and fever, paroxysmal autonomic instability with dystonia should be considered.

    Full Text Available The diagnosis of tuberculosis and lung cancer is difficult, as symptoms of both diseases are similar. Due to high TB prevalence and radiological similarities, a large number of lung cancer patients initially get wrongly treated for tuberculosis based on radiological picture alone. However, treating TB leads to inflammatory fibrosisin some of the patients. In all these cases, the diagnosis is confirmed only with a biopsy which is an invasive technique that is usually performed via Bronchoscopy or CT – guided biopsy. There comes the need of an efficient Computer Aided Diagnosis(CAD of the fibrosis and adenocarcinoma diseases. The increased chance of characterizing tissues with the help of CAD and the achievable workload reduction for the radiologist demand the usage of these systems in CT screenings as well as daily hospital practice. Generally, the CAD is designed based on the Region of Interest(ROI given by the radiologist which makes the system semi-automatic.Our work presents a fully automated method of characterization of carcinoma from other lung abnormalities namely fibrosis and suspicious of tuberculosis. A comparison study is also done by evaluating the performance of Adaptive Neuro-Fuzzy Inference System(ANFIS as a Classifier with three set of features. These feature set include entropy and parameters extracted by Gray Level Co-Occurrence Matrix(GLCM and Gray Level Run Length Matrix(GLRLM.

  18. Robust system for human airway-tree segmentation

    2008-03-01

    Robust and accurate segmentation of the human airway tree from multi-detector computed-tomography (MDCT) chest scans is vital for many pulmonary-imaging applications. As modern MDCT scanners can detect hundreds of airway tree branches, manual segmentation and semi-automatic segmentation requiring significant user intervention are impractical for producing a full global segmentation. Fully-automated methods, however, may fail to extract small peripheral airways. We propose an automatic algorithm that searches the entire lung volume for airway branches and poses segmentation as a global graph-theoretic optimization problem. The algorithm has shown strong performance on 23 human MDCT chest scans acquired by a variety of scanners and reconstruction kernels. Visual comparisons with adaptive region-growing results and quantitative comparisons with manually-defined trees indicate a high sensitivity to peripheral airways and a low false-positive rate. In addition, we propose a suite of interactive segmentation tools for cleaning and extending critical areas of the automatically segmented result. These interactive tools have potential application for image-based guidance of bronchoscopy to the periphery, where small, terminal branches can be important visual landmarks. Together, the automatic segmentation algorithm and interactive tool suite comprise a robust system for human airway-tree segmentation.

    As one of the most prevalent chronic disorders, airway disease is a major cause of morbidity and mortality worldwide. In order to understand its underlying mechanisms and to enable assessment of therapeutic efficacy of a variety of possible interventions, noninvasive investigation of the airways in a large number of subjects is of great research interest. Due to its high resolution in temporal and spatial domains, computed tomography (CT) has been widely used in clinical practices for studying the normal and abnormal manifestations of lung diseases, albeit there is a need to clearly demonstrate the benefits in light of the cost and radiation dose associated with CT examinations performed for the purpose of airway analysis. Whereas a single CT examination consists of a large number of images, manually identifying airway morphological characteristics and computing features to enable thorough investigations of airway and other lung diseases is very time-consuming and susceptible to errors. Hence, automated and semiautomated computerized analysis of human airways is becoming an important research area in medical imaging. A number of computerized techniques have been developed to date for the analysis of lung airways. In this review, we present a summary of the primary methods developed for computerized analysis of human airways, including airway segmentation, airway labeling, and airway morphometry, as well as a number of computer-aided clinical applications, such as virtual bronchoscopy. Both successes and underlying limitations of these approaches are discussed, while highlighting areas that may require additional work.

    Lung cancer is the most common and lethal malignancy in the world. The landmark National lung screening trial (NLST) showed a 20% relative reduction in mortality in high-risk individuals with screening low-dose computed tomography. However, the poor specificity and low prevalence of lung cancer in the NLST provide major limitations to its widespread use. Furthermore, a lung nodule on CT scan requires a nuanced and individualized approach towards management. In this regard, advances in high through-put technology (molecular diagnostics, multi-gene chips, proteomics, and bronchoscopic techniques) have led to discovery of lung cancer biomarkers that have shown potential to complement the current screening standards. Early detection of lung cancer can be achieved by analysis of biomarkers from tissue samples within the respiratory tract such as sputum, saliva, nasal/bronchial airway epithelial cells and exhaled breath condensate or through peripheral biofluids such as blood, serum and urine. Autofluorescence bronchoscopy has been employed in research setting to identify pre-invasive lesions not identified on CT scan. Although these modalities are not yet commercially available in clinic setting, they will be available in the near future and clinicians who care for patients with lung cancer should be aware. In this review, we present up-to-date state of biomarker development, discuss their clinical relevance and predict their future role in lung cancer management.

    The concept of personalized medicine, which aims to provide patients with targeted therapies while greatly reducing surgical trauma, is gaining popularity among Asian clinicians. Single port video-assisted thoracic surgery (VATS) has rapidly gained popularity in Hong Kong for major lung resections, despite bringing new challenges such as interference between surgical instruments and insertion of the optical source through a single incision. Novel types of endocutters and thoracoscopes can help reduce the difficulties commonly encountered during single-port VATS. Our region has been the testing ground and has led the development of many of these innovations. Performing VATS, in particular single-port VATS in hybrid operating theatre helps to localise small pulmonary lesions with real-time images, thus increasing surgical accuracy and pushes the boundaries in treating subcentimeter diseases. Such approach may be assisted by use of electromagnetic navigational bronchoscopy in the same setting. In addition, sublobar resection can also be more individualised according to pathologic tumour subtype that require rapid intraoperative diagnostic test to guide appropriate surgical therapy. A focus on technology and innovation for large tumours that require chest wall resection and reconstructions have also been on going, with new materials and prostheses that may be tailored to each individual needs. The current paper reviews the literature pertaining to the above topics and discusses recent related innovations in Hong Kong, highlighting the study results and future perspectives.

    Full Text Available Case. We report a rare case of hydralazine-induced anti-neutrophil cytoplasmic antibody-associated vasculitis. A 75-year-old African American woman with history of high blood pressure on hydralazine for 3 years presented with acute onset of shortness of breath and hemoptysis. Lab workup revealed a severe normocytic anemia and a serum creatinine of 5.09 mg/dL (baseline 0.9. Bronchoscopy demonstrated active pulmonary hemorrhage. A urine sample revealed red cell casts and a renal biopsy demonstrated pauci-immune, focally necrotizing glomerulonephritis with small crescents consistent with possible anti-neutrophil cytoplasmic antibody-positive renal vasculitis. Serologies showed high-titer MPO-ANCA and high-titer anti-histone antibodies. She was treated with intravenous steroids and subsequently with immunosuppression after cessation of hydralazine. The patient was subsequently discharged from hospital after a rapid clinical improvement. Conclusion. Hydralazine-induced anti-neutrophil cytoplasmic antibody-positive renal vasculitis is a rare adverse effect and can present as a severe vasculitic syndrome with multiple organ involvement. Features of this association include the presence of high titer of anti-myeloperoxidase anti-neutrophil cytoplasmic antibody with multiantigenicity, positive anti-histone antibodies, and the lack of immunoglobulin and complement deposition. Prompt cessation of hydralazine may be sufficient to reverse disease activity but immunosuppression may be needed.

    Full Text Available Objective. Our institution has been using a novel flexible laser fiber in pediatric surgical airway procedures, which has been quite successful. The purpose of this paper is to present our preliminary experience in the treatment of pediatric airway lesions using this laser technique. Methods. A case series reviewing 40 patients undergoing 95 laser procedures is reported. Indications included removal of suprastomal granulation tissue, removal of granulation after laryngotracheal reconstruction, subglottic and supraglottic stenoses, recurrent respiratory papillomas, subglottic hemangioma, laryngeal cleft, and left main stem bronchus stenosis. Procedures were performed via microdirect laryngoscopy and bronchoscopy. Results. No complications including postoperative glottic webs, concentric scar formation, or airway fires occurred in any of the patients (after the series was completed, we did experience an airway fire. It was a flash flame that was self-limited and caused no long-term tissue injury. Conclusions. The endoscopic application of a new flexible carbon dioxide laser fiber for management of pediatric airways lesions provides good outcomes in selected patients. Distal respiratory papillomas, subglottic stenosis, and granulation tissue are, in our experience, appropriate indications.

    Tracheal stenosis is a potential complication of tracheostomy. The present study aimed to describe the epidemiologic profile of subglottic stenosis in a referral medical centre. During a 4-year period, all patients who had been admitted in an Intensive Care Unit of Imam Khomeini Hospital (affiliated to Tehran University of Medical Sciences) and had undergone percutaneous tracheostomy during 7-10 days after endotracheal intubation were enrolled in the study. After removing the tracheostomy tube, patients were evaluated regarding development of tracheal stenosis using fiberoptic bronchoscopy and multi-slice computed tomography scan. During the study period, percutaneous tracheostomy was performed in 140 patients with a mean age of 38 years. Overall 54 patients died due to the severity of the disorder during hospitalization. In the remaining 86 patients, 54 cases needed permanent or long-term mechanical ventilation and were excluded from the study. Twelve patients died during the first 3 months and 20 patients were left for final assessment. Multi-slice computed tomography scan imaging showed subglottic stenosis in 17 cases (85%). Of these, 9 patients (52%) had tracheal stenosis of subglottic stenosis is frequent in patients who have undergone percutaneous tracheostomy in the Intensive Care unit setting. However, the stenosis is generally mild and is not associated with serious and/ or life-threatening clinical manifestations.

    The aim of this study was to describe the findings on plain chest radiographs in patients with herpes simplex virus pneumonia (HSVP). The study was based on 17 patients who at a retrospective search have been found to have a monoinfection with herpes simplex virus. The diagnosis was established by isolation of the virus from material obtained during fiberoptic bronchoscopy (FOB) which also included broncho-alveolar lavage and tissue sampling. Fourteen patients had a chest radiograph performed within 24 h of the date of the FOB. Two radiographs showed no abnormalities of the lung parenchyma. The radiographs of the other 12 patients showed lung opacification, predominantly lobar or more extensive and always bilateral. Most patients presented with a mixed airspace and interstitial pattern of opacities, but 11 of 14 showed at least an airspace consolidation. Lobar, segmental, or subsegmental atelectasis was present in 7 patients, and unilateral or bilateral pleural effusion in 8 patients, but only in 1 patient was it a large amount. In contradiction to the literature which reports a high correlation between HSVP and acute respiratory distress syndrome (ARDS), 11 of 14 patients did not meet the pathophysiological criteria for ARDS. The radiologist may suggest the diagnosis of HSVP when bilateral airspace consolidation or mixed opacities appear in a susceptible group of patients who are not thought to have ARDS or pulmonary edema. The definite diagnosis of HSV pneumonia can be established only on the basis of culture of material obtained by broncho-alveolar lavage. (orig.)

    Full Text Available Background. Legionnaires' disease (LD is a pneumonia caused by Legionella pneumophila (LP. The disease occurs more often in immunocompromised persons and can be manifested by severe pneumonia, multiple organ failure and has a high mortality. Case report. Immunocompetent patient, male, 53- year old, with severe form of LB had fever, cough, weakness and diarrhea as the initial symptoms of the disease. Laboratory results showed increased number of leukocytes, increased values of acute phase proteins, liver enzymes and hyponatremia. Computed tomography of the chest showed the marked inflammatory lesions on both sides. Pathohystological analysis of the samples retrieved by bronchoscopy pointed to a pneumonia, and diagnosis of LD was confirmed by positive urine test for LP antigen. Later, the disease was complicated by acute adult respiratory distress syndrome (ARDS. Treatment with antibiotics (erythromycin, rifampicin, azithromycin combined with ARDS treatment led to a clinical recovery of the patient together with complete resolution of inflammatory lesions seen on chest radiography. Conclusion. In severe pneumonias it is necessary to consider LD in differential diagnosis, perform tests with aim of detecting LP and apply adequate antibiotic treatment in order to accomplish positive outcome of the therapy and prevent complications.

    Background Pepsin plays a role in gastroesophageal reflux (GER). Aims of this study were to verify if pepsin could be the cause of frequent bronchial exacerbations and to check if the persistence of chronic respiratory symptoms were correlated with pre-existing respiratory diseases. Methods From January to May 2016, 42 patients underwent a diagnostic bronchoscopy. All patients had a history of at least one bronchial exacerbation during the previous year. Bronchial lavage fluid specimens were obtained. A semiquantitative assessment of pepsin in the samples was carried out based on the intensity of the test sample. Results Pepsin was present in 37 patients (88%), but in patients with bronchial asthma and chronic obstructive pulmonary disease (COPD), the finding of pepsin in the bronchoalveolar fluid was 100%. There was a strong positive statistical correlation between pepsin detection and radiological signs of GER (ρ=0.662), and between pepsin detection and diagnosis (ρ=0.682). No correlation was found between the bacteriology and the presence of pepsin in the airways (ρ=0.006). Conclusions The presence of pepsin in the airways shows the occurrence of reflux. The persistence of respiratory symptoms by at least 2 months suggest an endoscopic bronchial examination. This straightforward test confirms the cause possible irritation of the airways and may prevent further diagnostic tests, such as an EGD or pH monitoring esophageal. PMID:27668224

    Full Text Available Abstract Background Glomus tumor is an uncommon neoplasm derived from cells of the neuromyoarterial glomus or glomus body. Most glomus tumours occur in the dermis and subcutaneous tissues. A case of a primary pulmonary glomus tumour originating in the right upper lobe is presented. Case presentation A 74-yr-old male was admitted with siccus cough, dyspnea and right-sided chest pain. Computed tomography of the thorax revealed a 4 cm growth of the right upper lobe. Fiberoptic bronchoscopy demonstrated an endobronchial hypervascular mass causing obstruction of the apical segmental bronchus. Pathology report was consistent with pulmonary glomus tumor. The patient underwent a typical right upper lobectomy with mediastinal lymph node dissection. Twelve months later he is free of disease. Conclusion Occasionally glomus tumors can occur in extracutaneous sites such as the gastrointestinal tract, bone, genitourinary system and respiratory tract. Primary pulmonary glomus tumors are very rare (our case is the 19th one presented in the international literature and are often confused with other solid neoplasms such as carcinoids, hemangiopericytomas and tumors belonging to the family of Ewing's sarcoma/primitive neuroectodermal tumours.

    Full Text Available Pneumonitis is a rare but serious complication associated with paclitaxel and/or trastuzumab treatment. We report a 51-year-old female patient with locally advanced breast cancer who presented with shortness of breath, fever, dry cough and pulmonary infiltrates. She had been treated without complications for 10 weeks with paclitaxel (Taxol® and trastuzumab (Herceptin® as neoadjuvant therapy, with complete clinical and pathological response. Infections and cardiomyopathy were excluded as causes of her symptoms. Bronchoscopy and biopsy were performed and a diagnosis of drug-induced interstitial pneumonitis was made. After treatment with steroids, the patient showed a significant response in less than 24 h; she was discharged home without the need for oxygen less than 48 h after therapy initiation. Although no causative association could be found between either trastuzumab or paclitaxel and this patient’s pulmonary syndrome, the potential for such toxicity should be considered, especially as paclitaxel/trastuzumab is a vey common combination therapy for breast cancer.

    Trefoil factors (TFFs) 1, 2 and 3 are small polypeptides that are co-secreted with mucin throughout the body. They are up-regulated in cancer and inflammatory processes in the gastrointestinal system, where they are proposed to be involved in tissue regeneration, proliferation and protection. Our aim was to explore their presence in pulmonary secretions and to investigate whether they are up-regulated in pulmonary diseases characterized by mucin hypersecretion. Bronchioalveolar lavage fluid was obtained from 92 individuals referred to bronchoscopy. The patients were grouped according to diagnosis and pulmonary function. The concentrations of TFF1, TFF2 and TFF3 were measured by ELISA. All three peptides were detected in bronchioalveolar lavage fluid. Patients with chronic obstructive pulmonary disease had concentrations two to three times above the levels in the healthy reference group, and patients with pulmonary malignancies had concentrations of TFF1 and TFF2 three times that of the reference group. The results suggest that TFFs are involved in tissue regeneration, proliferation and protection in lung diseases.

Most cases are successfully managed with anterior or posterior nasal packing. However, the complications of nasal packing should be always considered. We report the case of a 78-year-old man with Alzheimer’s disease who was treated for anterior epistaxis with anterior nasal packing using three pieces of antibiotic-soaked gauze. Two days later, the patient was admitted to the emergency department in respiratory distress. A chest x-ray demonstrated atelectasis of the right lung. During an examination of the nasal cavities, the nasal packing was removed, and one of the gauze pieces was missing. The patient underwent rigid bronchoscopy, and the missing gauze was found to be obstructing the right main bronchus. The patient’s respiratory function improved considerably after removal of the foreign body. It is assumed that gauze packs should be used with caution in patients with an impaired level of consciousness and neurodegenerative diseases.Keywords: epistaxis, nasal packing, aspiration, Alzheimer’s disease, cough reflex

    Injuries of the chest isolated or joined with injuries of other organs are distinctly increasing. There are almost no polytraumatic people without thorax injuries. Traffic traumas have a dominant role in causing these injuries. We had most injuries in sammer months. The isolated chest injurie we had 60% and the accompanying injurie 40%. Of the accompanying injuries, the head injurie have the most autstanding place, which especially make difficult the diagnostics, and curing. In heavy injuries of the thorax with paradoxical breathing and on both sides of the leasions, establishing the internal pneumatic stabilisation at the beginning by pulmomatic and then ostheosyntesis of ribs are the most effective therapy. In order to prevent the infections, atracheobronchial dressing with antibiotics is performed as well as the regular X-ray check. As a general rule than 200 ml. per 3 hour requires operative control of the hemorrhage. We had 5,6% thoracothomy after continuous drainage by persstend hemorrhage. The obstructive pneumonia, particularly the eldery are to avoid obstructis, aspiration by catheter with bronchoscopy.
