1/61. radiation-induced bronchial stenosis: a new cause of platypnea-orthodeoxia.Platypnea-orthodeoxia is encountered in a variety of cardiac, pulmonary, and hepatic disorders. We report its occurrence in a 59-year-old man who had had combined external-beam and high dose-rate iridium brachytherapy for a stage I non-small-cell carcinoma of the right upper lobe 2 years earlier. The post-radiation course was complicated by a severe radiation bronchitis; the onset of platypnea-orthodeoxia signalled the development of severe bronchial stenosis that was transiently relieved, initially by dilatation, and later by stent placement, though the patient ultimately died of a pulmonary hemorrhage. The dosage of brachytherapy given, the combined external-beam therapy, and the long survival after completion of radiation therapy were likely factors in the development of bronchial stenosis. We discuss the tomographic and bronchoscopic features of radiation-induced bronchial stenosis.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
2/61. A possible mechanism of primary ciliary dyskinesia: a case of a segmental defect in ciliary microtubules.We report here a 13-year-old woman with cough, sputum and fever. The patient had both chronic sinusitis and bronchitis. Chest X-ray and computed tomographic scan of the chest revealed mucous bronchial filling and bronchiectasia in bronchi of bilateral lower lobes, right middle lobe and left upper lobe. Aerosol inhalation scintigraphy with 99mTechnetium demonstrated delays of the discharged tracer. On the basis of these findings, primary ciliary dyskinesia was suggested. This was confirmed by the findings from nasal biopsy with transmission electron microscopy where all of the microtubules were segmentally defected near the basal body in the cilia. On the basis of these findings, we diagnosed the patient with primary ciliary dyskinesia which may be due, at least in part, to segmental defect of ciliary microtubules.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
3/61. Herpetic tracheitis and brachial plexus neuropathy in a child with burns.Herpetic tracheobronchitis is a well-recognized clinical entity that most commonly occurs in immunocompromised patients, including patients with burns. Although the diagnosis of herpetic tracheobronchitis is usually not made until postmortem examination, the presence of the condition can be established when histologic specimens of a patient with upper airway obstruction are studied. In this article, a case is described in which a child developed herpetic tracheitis after undergoing elective intubation after the grafting of burns of the face, neck, and upper extremity. The tracheitis resulted in severe upper airway obstruction that required tracheal dilatation and sequential bronchoscopic excisions of granulation tissue. The patient also developed a brachial plexus neuropathy that was most likely related to herpetic infection.- - - - - - - - - - ranking = 3keywords = upper (Clic here for more details about this article) |
4/61. Acute epiglottitis despite vaccination with haemophilus influenzae type b vaccine.We present the case of a 20-month-old child who required admission to the intensive care with a presumptive diagnosis of acute laryngo-tracheo-bronchitis, for the management of acute upper airway obstruction. This child had received a complete course of haemophilus influenzae type b (Hib) vaccine. Subsequent events showed that the diagnosis was not laryngo-tracheo-bronchitis but acute epiglottitis. We propose that a full course of vaccination is no guarantee against a subsequent illness with Hib and may actually lead to the wrong diagnosis and possibly life-threatening consequences.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
5/61. pseudomonas orbital cellulitis.A 3-month-old infant being treated for bronchitis developed a rapid onset but otherwise typical orbital cellulitis. Because gram-negative infections and septicemia are common occurrences in the newborn nursery, this patient was given systemic gentamicin and ampicillin. Sinus x-rays were not attempted. Two days after treatment the eyelids were opened. A strikingly large corneal ulcer with perforated globe and endophthalmitis was found. pseudomonas aeroginosa was cultured from the blood, conjunctiva, and throat. A diagnosis of pseudomonas orbital cellulitis with secondary corneal perforation and endophthalmitis was made. The source of infection was believed to be the respiratory tract.- - - - - - - - - - ranking = 6635.7593913507keywords = respiratory tract, tract (Clic here for more details about this article) |
6/61. Membranous laryngotracheobronchitis (membranous croup).Membranous laryngotracheobronchitis (membranous croup), not previously described as a distinct entity, is characterized by diffuse inflammation of the larynx, trachea, and bronchi with adherent or semiadherent mucopurulent membranes in the subglottic trachea (conus elasticus) and in the upper trachea distal to the conus elasticus. We reviewed 28 cases of membranous croup diagnosed by endoscopy and/or radiographic examination. The importance of the recognition of membranous croup as a distinct entity is discussed. The characteristic radiologic findings consist of subglottic tracheal narrowing, irregularity of contour of the proximal tracheal mucosa, and sometimes detached or partially detached proximal tracheal membranes, which can be mistaken for tracheal foreign bodies.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
7/61. Clinical and histopathological findings in two Turkish children with follicular bronchiolitis.We report on two Turkish children who presented with progressive airway obstruction. Open lung biopsy revealed follicular bronchiolitis. The children were treated with systemic steroids and various topical medications. Whereas the respiratory situation of patient 1 required immunosuppressive therapy, the condition of patient 2 stabilised without systemic medication. CONCLUSION: diagnosis of follicular bronchiolitis should be considered when children present with recurrent respiratory tract infections, progressive dyspnoea, and chronic bronchial obstruction. Children in whom follicular bronchiolitis is suspected should undergo open lung biopsy for confirmation of diagnosis.- - - - - - - - - - ranking = 29501.170819657keywords = respiratory tract infection, respiratory tract, tract infection, tract (Clic here for more details about this article) |
8/61. Aspergillus laryngotracheobronchial infection in a 6-year-old girl following bone marrow transplantation.Localised fungal infection of the larynx and tracheobronchial tree is extremely uncommon. We report the case of a 6-year-old girl with acute lymphocytic leukaemia, who developed symptoms of upper airways obstruction 6 months after a cord blood transplant. bronchoscopy showed a pale plaque lesion in the larynx and tracheobronchial tree. aspergillus fumigatus was cultured from a biopsy of the lesion. The patient was treated successfully with a prolonged course of amphotericin b and assessed with multiple surveillance bronchoscopies.- - - - - - - - - - ranking = 1keywords = upper (Clic here for more details about this article) |
9/61. Tracheobronchial involvement with Crohn's disease.We report the case of a young woman with Crohn's disease of the bowel who presented with a purulent tracheobronchitis and life-threatening upper airway obstruction. Fibreoptic bronchoscopy demonstrated severe tracheal and upper bronchial pseudotumours and stenosis. The role of recent discontinuation of corticosteroids, for quiescent inflammatory bowel disease, in the development of endobronchial disease and the dramatic response in airway patency after reintroduction of prednisolone in this rare complication of Crohn's disease are discussed.- - - - - - - - - - ranking = 2keywords = upper (Clic here for more details about this article) |
10/61. pneumothorax complicating pulmonary emphysema.Clinical and roentgenographic findings were compared in patients 40 years of age and over and in those under 40 who were treated for acute unilateral pneumothorax. dyspnea and anxiety were pominent in the older individuals, although pneumothoraces were usually small. Because physical findings were often unreliable, roentgenograms were required. In the presence of pulmonary emphysema, loss of retractility prevented total collapse of the underlying lung. Increased intrapleural pressure caused over-expansion of the chest wall and the depression of the diaphragm without much mediastinal shifting. Partial collapse of emphysematous lobes demonstrated bullae that were not previously obvious. Respiratory failure developed in five patients over 40 years of age, but four of them recovered after relief of the pneumothorax. mortality for the group was low and related to associated pulmonary diseases.- - - - - - - - - - ranking = 12.421004643073keywords = tract (Clic here for more details about this article) |
