1/152. Wegener's granulomatosis causing laryngeal and tracheobronchial obstruction in an adolescent girl.A 12-year-old girl presenting with a painful neck mass and ulcerated gingival lesions was found to have Wegener's granulomatosis involving the gingivae, paranasal sinuses, ears, mastoids, larynx, trachea, bronchial tree, lungs, kidneys and joints. The initial illness and two subsequent exacerbations were treated with intravenous and oral cyclophosphamide and prednisone. Secondary infections have been managed with establishment of good drainage and use of appropriate antibiotics. The patient is well with a normal sedimentation rate 4 1/2 years after the onset of her disease.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
2/152. Upper aerodigestive tract frostbite complicating volatile substance abuse.Volatile substance abuse has become increasingly popular among today's youth. It has reportedly been used by up to 13% of teenage populations. physicians need to be aware of the potential complications which may arise from this form of substance abuse. We describe the case of a young male who presented with massive edema affecting his lips, oral cavity, oropharynx and trachea. It was later discovered that his injury was secondary to thermal trauma related to the abuse of a fluorinated hydrocarbon propellant. This presentation may easily be confused with allergic or angioneurotic edema. Denial by the patient can lead to a further delay in diagnosis. This case is especially notable since frostbite injury involving the upper aerodigestive tract is extremely rare. We discuss the differential diagnosis and the management principals required in the care of this patient. We also present a pertinent review of the literature related to both volatile substance abuse and its complications involving the airway.- - - - - - - - - - ranking = 1.0680731300503keywords = airway (Clic here for more details about this article) |
3/152. Airway coccidioidomycosis--report of cases and review.infection due to coccidioides immitis usually begins in the lungs. Despite the initial pulmonary portal of entry, endotracheal and endobronchial coccidioidomycosis has rarely been described. Since the introduction of fiberoptic bronchoscopy and the AIDS epidemic, more C. immitis lesions of the large airways have been noted. We present data on 38 cases of coccidioidomycosis of the airways, including 6 cases detailed from our own experience and 32 from the literature. Direct infection of the airways (28 cases) is a more common mechanism of airways disease than is erosion into the airways from a lymph node (5 cases). Bronchoscopic findings vary and may show mucosal involvement or intrinsic obstruction. Endotracheal and endobronchial disease is not a self-limited disease and requires antifungal therapy. Disseminated disease in these patients is common. coccidioidomycosis must be considered in the differential diagnosis of airway pathology.- - - - - - - - - - ranking = 6.6584387803017keywords = airway, obstruction (Clic here for more details about this article) |
4/152. thyroid gland hematoma after blunt cervical trauma.Thyroid hematoma is a rare cause of airway obstruction in victims of blunt trauma. The case of a 34-year-old woman who developed orthopnea after a low-energy motor vehicle accident is described. Presenting greater than 24 hours after her accident, the patient noted dysphagia, tracheal deviation, and postural dyspnea. The diagnosis of thyroid gland hematoma was made with a combination of fiberoptic laryngoscopy, cervical computed tomography, and great vessel and carotid angiography. Invasive airway management was not required. The patient underwent a total thyroidectomy and recovered without complications.- - - - - - - - - - ranking = 8.4630992749195keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
5/152. Bronchodilator responsiveness in a ventilator-dependent infant with severe tracheobronchomalacia.A neonatal case of severe, ventilator-dependent tracheobronchomalacia (TBM) is described. The extent of the malacic segment was determined by endoscopy and tracheobronchography. Additionally, relevant and ever increasing reversible peripheral airway obstruction was documented by measuring the mechanical properties of the respiratory system before and after salbutamol. With the combination of endoscopically guided aortopexy and salbutamol infusion, the infant was eventually weaned from mechanical ventilation at the age of 86 days. We speculate that in ventilator-dependent infants with severe TBM the determination of bronchodilator responsiveness may have clinical consequences.- - - - - - - - - - ranking = 7.3950261448692keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
6/152. Recurrent pregnancy-related upper airway obstruction caused by intratracheal ectopic thyroid tissue.An unusual case of recurrent pregnancy-related thyroid growth stimulation is reported. A 27-year-old euthyroid woman had pulmonary symptoms, thought to be asthma during her first pregnancy, that improved postpartum. Bronchodilatators had no effect and symptoms recurred from gestational week 22 during her second pregnancy. Her 58-mL multinodular goiter (by ultrasound) was not thought to be responsible for her upper airway symptoms. Therefore, fiber laryngoscopy and computed tomographic (CT) scan were performed and revealed a 20 x 15 x 10 mm intratracheal tumor. After tracheostomy and microlaryngoscopy, benign goitrous thyroid tissue was removed through a tracheal fissure during gestational week 35. Postoperatively the patient had stopped medication and was without any pulmonary symptoms. The child was delivered by cesarean section in gestational week 39. apgar score was normal and the child has developed normally. We believe that this case illustrates the recurrent effect of pregnancy-related thyroid tissue stimulation by a combination of increasing human chorionic gonadotropin (hCG) stimulation and iodine deficiency in a borderline iodine-deficient region. This is the first report on symptomatic intratracheal ectopic thyroid tissue diagnosed during pregnancy.- - - - - - - - - - ranking = 30.648177709527keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
7/152. Lingeous conjunctivitis with tracheal obstruction. A case report, with light and electron microscopy findings.A white male infant of 1 year had unilateral membranous conjunctivitis and severe laryngotracheobronchitis which required tracheostomy. Cultures from eye and throat swabs and of fluid suctioned through the tracheostomy grew many organisms, including H. influenzae, adenovirus type 3, and candida species, but he had no specific immunologic disturbance. Ligneous conjunctivitis was diagnosed. The infant's general condition responded slowly to intensive therapy but the membrane continued to slough off the regrow. The excised membrane contained massive subepithelial deposits of eosinophilic material and a moderately vascular chronic inflammatory-cell infiltrate with numerous mast cells in the perivascular spaces and the hyaline membrane. The conjunctivitis cleared when treated with topical sodium cromoglycate (Intal), a known inhibitor of mediator release from mast-cell granules. The success of Intal therapy in this case supports the theory that mast cells are involved in the pathogenesis of ligneous conjunctivitis.- - - - - - - - - - ranking = 1keywords = obstruction (Clic here for more details about this article) |
8/152. Tracheal ring herniation following percutaneous dilatational tracheostomy and its resection under endoscopic control.A 76-year-old patient had an elective percutaneous dilatational tracheostomy (PDT) under endoscopic control in the intensive care unit. Twelve days later when her general condition improved, two attempts at decannulation failed due to upper airway obstruction above the tracheostomy site. bronchoscopy showed herniation of the anterior tracheal wall above the tracheostomy tube occluding 80 per cent of the lumen. The herniated anterior segment was elevated and partially resected under endoscopic guidance. The patient made a full recovery and was decannulated on the first post-operative day. Pitfalls and possible complications of PDT are discussed.- - - - - - - - - - ranking = 7.3950261448692keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |

10/152. Laryngotracheobronchial involvement in a patient with nonendemic rhinoscleroma.We report the first case of rhinoscleroma in an Israeli citizen, a former sailor with a transatlantic shipping company. Characteristic histologic changes from a tracheal biopsy and isolation of klebsiella rhinoscleromatis from a blood culture after diagnostic bronchoscopy confirmed the diagnosis. Extreme delay in the diagnosis, a not uncommon feature in nonendemic areas, was associated with severe advanced laryngotracheobronchial disease. Treatment with quinolones was followed by significant improvement, but the patient died 1 month after presentation, apparently from upper airway obstruction.- - - - - - - - - - ranking = 7.3950261448692keywords = airway obstruction, airway, obstruction (Clic here for more details about this article) |
