1/35. pulmonary eosinophilia associated with montelukast.Antileukotriene drugs are new therapeutic agents that have recently been approved for the treatment of asthma. Several cases of eosinophilic conditions including churg-strauss syndrome have been reported to be associated with zafirlukast, a cysteinyl leukotriene type 1 receptor antagonist. So far no other leukotriene modifier has been associated with the syndrome. The case history is presented of a man with allergic rhinitis and asthma who had received intermittent pulse therapy with oral corticosteroids. pulmonary eosinophilia developed while he was receiving treatment with montelukast, a chemically distinct cysteinyl leukotriene type 1 receptor antagonist. After discontinuation of montelukast therapy and administration of systemic corticosteroids the patient's symptoms reversed rapidly and there was prompt resolution of the pulmonary infiltrates. We believe that cysteinyl leukotriene type 1 receptor antagonists are safe and effective drugs for most patients with asthma but caution is needed for those with more severe disease who require systemic corticosteroids, especially if they show characteristics of the atypical allergic diathesis seen in the prodromal phase of churg-strauss syndrome.- - - - - - - - - - ranking = 1keywords = cyst (Clic here for more details about this article) |
2/35. Vallecular cyst: report of four cases--one with co-existing laryngomalacia.Congenital vallecular cysts are rare. In this report, four infants having vallecular cysts encountered over a six-year period from 1992 to 1997 were reviewed. All of them presented with upper aerodigestive tract symptoms. Marsupialization was performed in three of them and CO2 laser excision was performed in the fourth patient. There was no recurrence of the cyst in any patient. One of them also had co-existing laryngomalacia. The degree of airway collapse caused by laryngomalacia improved after cyst removal. The laryngomalacia resolved spontaneously. cyst fluid culture was performed in one of the patients and yielded staphylococcus aureus but there was no other definite indicator of infection. staphylococcus aureus could also be isolated in the respiratory tract from two of the other patients.- - - - - - - - - - ranking = 2.6666666666667keywords = cyst (Clic here for more details about this article) |
3/35. Congenital supraglottic cyst: a rare cause of stridor.Congenital laryngeal cysts are very rare and if mismanaged, lead to a high incidence of morbidity and mortality. The case may present as severe stridor and emergent management can obviate a tracheostomy, achieving cure in the process. We report here a case of supraglottic cyst, which was completely occluding the airway and was managed in the emergency setting.- - - - - - - - - - ranking = 2keywords = cyst (Clic here for more details about this article) |
4/35. Negative extrathoracic pressure in infants with cystic fibrosis and respiratory failure.Respiratory support using negative extrathoracic pressure or high-frequency chest wall oscillation was used to treat 3 infants with cystic fibrosis and respiratory failure who had not responded to maximal medical therapy. Beneficial clinical effects were noted in all three cases. Pulmonary function testing was performed in 2 cases, and measures of compliance increased.- - - - - - - - - - ranking = 1.6666666666667keywords = cyst (Clic here for more details about this article) |
5/35. Use of montelukast in the treatment of early childhood wheezing from clinical experience with three cases.leukotrienes were found to be raised in respiratory syncytial virus bronchiolitis. Montelukast is a cysteinyl leukotrienes antagonist. We report our experience with the use of montelukast in three young children from 5-months to 20-months old. The first case was a 5-month-old boy with previous good health. He had prolonged respiratory distress secondary to adenovirus type 3 infection. The second case was a 20-month-old boy with bronchopulmonary dysplasia. He had respiratory syncytial virus and an adenovirus type 3 infection leading to prolonged wheeze. The third case was a 20-month-old girl with chronic lung disorder after an episode of severe E. coli pneumonia at 1 month old. She developed acute virus-negative severe wheeze after a few days of running nose and low-grade fever. All three cases responded poorly to inhaled steroids and bronchodilators. Addition of montelukast was associated with marked clinical improvement within 1 week. The three cases were very heterogeneous and differed from usual simple virus-induced acute bronchiolitis. The use of multiple drugs including montelukast did not enable any definite conclusions; however, the addition of montelukast was closely related to clinical improvement. Further studies in the use of montelukast in severe virus-induced bronchiolitis are warranted.- - - - - - - - - - ranking = 0.33333333333333keywords = cyst (Clic here for more details about this article) |
6/35. Oncocytic laryngeal cysts: a case report and literature review.Some 150 cases of oncocytic laryngeal cysts have been published. We report another case of laryngeal oncocytic cysts with atypical presentation of acute, progressive stridor and sore throat. literature was reviewed with special regard to etiology, clinical presentation, imaging, incidence, localization, associated lesions and treatment options. Oncocytic laryngeal cysts are rare, but may be underreported. They represent a separate clinicopathological entity in the group of all laryngeal cysic lesions and occur in persons over 60 years. The symptomatology varies from asymptomatic to hoarseness and dyspnea. Diagnosis is made by histological examination. Treatment is surgical. Although it is a benign lesion, follow up is recommended, as recurrence is possible.- - - - - - - - - - ranking = 2.3333333333333keywords = cyst (Clic here for more details about this article) |
7/35. Unusual case of stridor and wheeze in an infant: tracheal bronchogenic cyst.Bronchogenic cysts are congenital anomalies that represent aberrant development of the foregut. Bronchogenic cysts in the mediastinum have been documented in both children and adults, but only one case of tracheal bronchogenic cyst in an infant was found in the literature. We report on a case of an infant with wheeze, stridor, and retractions, caused by a midtracheal bronchogenic cyst. This entity, with its unusual location, should be considered in the differential diagnosis of respiratory distress, cyanotic spells, wheezing, and stridor in infants.- - - - - - - - - - ranking = 224.17271502979keywords = bronchogenic cyst, bronchogenic, cyst (Clic here for more details about this article) |
8/35. Congenital laryngeal cyst: a case report.Congenital laryngeal cysts are a rare cause of stridor in the neonate. Nevertheless, delayed diagnosis and treatment can cause life-threatening airway obstruction. Even though the diagnosis is easily made by careful inspection, treatment results often in recurrence. These facts are illustrated by a case of a baby with a saccular cyst. Immediately after diagnosis and 5 days later the cyst was de-roofed using a CO2 laser via an endolaryngeal approach. Because of a second recurrence an excision of the cyst was performed via a lateral cervical approach.- - - - - - - - - - ranking = 2.6666666666667keywords = cyst (Clic here for more details about this article) |
9/35. Ectopic subglottic thymic cyst: a rare cause of congenital stridor.We describe the case of a 10-day-old boy who was brought to the hospital with stridor and respiratory distress. He was diagnosed with stenosis caused by a subglottic cyst. After the cyst was removed endoscopically, the patient's symptoms resolved. pathology identified the cyst as ectopic thymic tissue. This case is noteworthy because we believe it represents the first reported instance of ectopic thymic tissue in the subglottis.- - - - - - - - - - ranking = 2.3333333333333keywords = cyst (Clic here for more details about this article) |
10/35. anesthesia induction for a difficult intubation infant with a laryngeal cyst.We report a case of difficult airway in a 37-day-old female with a laryngeal cyst during induction of general anesthesia. This case illustrates that upper airway obstruction can occur during induction of anesthesia with an unusual infantile aryepiglottic fold cyst. In this case, successful orotracheal intubation was achieved with spontaneous respiration, and preoperative information on orientation of the lesion assisted in positioning the patient to minimize the degree of dynamic obstruction.- - - - - - - - - - ranking = 2keywords = cyst (Clic here for more details about this article) |
