1/38. Pulmonary failure after Norwood procedure: indication for extracorporeal membrane oxygenation? A case report.Today some authors consider univentricular repair a contraindication for postoperative cardiac extracorporeal membrane oxygenation (ECMO). The question is whether or not ECMO is indicated as pulmonary support in case of an overwhelming pulmonary infection during the postoperative course after a Norwood procedure. During the prolonged weaning period after a Norwood procedure using a 4 mm aortopulmonary shunt, proven respiratory syncytial virus (RSV) bronchiolitis occurred at the time of expected weaning from artificial ventilation. Venovenous ECMO was able to improve oxygenation, but when pulmonary opacification failed to resolve, ECMO was terminated after 12 days.- - - - - - - - - - ranking = 1keywords = bronchiolitis (Clic here for more details about this article) |
2/38. bronchiectasis and bronchiolitis obliterans post respiratory syncytial virus infection: think again.Respiratory syncytial virus (RSV) lower respiratory tract infections are common, yet long-term sequelae in previously healthy infants and children are rarely reported. We report a child who developed bronchiectasis and bronchiolitis obliterans following an RSV lower respiratory tract infection but in whom adenovirus was detected on stored serum. Co-infection with adenovirus is the likely cause for the bronchiectasis and bronchiolitis obliterans.- - - - - - - - - - ranking = 7.7933754468129keywords = bronchiolitis, bronchiolitis obliterans, obliterans (Clic here for more details about this article) |
3/38. The pharmacologic mechanism by which inhaled epinephrine reduces airway obstruction in respiratory syncytial virus-associated bronchiolitis.Inhaled racemic epinephrine relieves airway obstruction in patients with respiratory syncytial virus bronchiolitis. The contribution of alpha- versus beta-adrenoreceptor stimulation toward this clinical effect is unknown. We describe an infant treated with propranolol for supraventricular tachycardia in whom respiratory syncytial virus bronchiolitis developed. Inhaled racemic epinephrine improved his respiratory symptoms, whereas nebulized albuterol did not.- - - - - - - - - - ranking = 6keywords = bronchiolitis (Clic here for more details about this article) |
4/38. Respiratory syncytial virus infection in patients with phagocyte defects.patients with phagocyte defects frequently develop bacterial or fungal pneumonias, but they are not considered to be at increased risk for viral infections. We describe 3 patients with known phagocyte immunodeficiencies who developed lower respiratory tract infections (LRTI) caused by respiratory syncytial virus (RSV). All 3 patients had dense pneumonias as indicated by computed tomography scan of the lungs and RSV was recovered. We conclude that RSV can present as a dense pneumonia in patients with phagocyte defects. Along with common pathogens causing LRTI, RSV should be considered in the differential diagnosis. Viral cultures as well as rapid antigen detection assays for respiratory viruses should be included in the evaluation of LRTI in patients with phagocyte defects. respiratory syncytial virus, phagocyte, immunodeficiency, pneumonia.- - - - - - - - - - ranking = 0.18031645486558keywords = pneumonia (Clic here for more details about this article) |
5/38. Donor lymphocyte infusion for treatment of life-threatening respiratory syncytial virus infection following bone marrow transplantation.We describe two patients who developed respiratory syncytial virus (RSV) pneumonia after BMT. One died of RSV pneumonia after three courses of steroid pulse therapy. Surprisingly, RSV antigen was identified in the bronchoalveolar lavage fluid (BALF) obtained post mortem. Steroid pulse therapy might have suppressed anti-RSV immunity, leading to persistent RSV infection for more than 1 month. The other patient received donor lymphocyte infusions (DLI) for relapsed plasma cell leukemia, while having active RSV pneumonia. His respiratory condition improved after DLI, and RSV antigen disappeared in BALF and nasal swabs. DLI might be effective in cases of life-threatening RSV pneumonia.- - - - - - - - - - ranking = 0.18031645486558keywords = pneumonia (Clic here for more details about this article) |
6/38. weaning to extubation directly from high-frequency oscillatory ventilation in an infant with cystic lung disease and persistent air leak: a strategy for lung protection.We report the successful weaning and extubation of an infant from a SensorMedics 3100A high-frequency oscillator without returning to conventional ventilation. A 7-week-old term infant with respiratory syncytial virus bronchiolitis complicated by cystic pulmonary lesions repeatedly failed attempts to return to conventional ventilation from high-frequency oscillatory ventilation (HFOV) for weaning, because of recurrent pneumothoraces. A computed tomography of the chest revealed multiple well defined cysts of various sizes involving both lungs. Therefore, weaning to extubation from HFOV was proposed as a way of preventing further air leak. The weaning strategy consisted of a technique we refer to as "sprinting." Using this method, the patient was successfully extubated directly from HFOV, with no complications. A follow-up computed tomography of the chest showed marked improvement in the size of the cystic lesions. The patient was discharged home with no need for home oxygen therapy.- - - - - - - - - - ranking = 1keywords = bronchiolitis (Clic here for more details about this article) |
7/38. Encephalopathy associated with respiratory syncytial virus bronchiolitis.Respiratory syncytial virus is an extremely common cause of childhood respiratory infections resulting in significant morbidity and mortality. Although apnea is a well-known complication in young infants with respiratory syncytial virus bronchiolitis, the encephalopathy associated with this infection is not well recognized. Our study reveals an incidence of encephalopathy of 1.8% in a total of 487 patients with respiratory syncytial virus bronchiolitis studied over a period of almost 4 years. seizures were the presenting complication. Based on our study of a cohort of children with respiratory syncytial virus bronchiolitis, we believe that neurologic complications, although relatively uncommon, represent a significant component of this common childhood illness. Furthermore, respiratory syncytial virus has been shown to release several mediators that could directly or indirectly be neurotoxic and induce an encephalopathy associated with the respiratory illness.- - - - - - - - - - ranking = 7keywords = bronchiolitis (Clic here for more details about this article) |
8/38. Respiratory syncytial virus infection in the late bone marrow transplant period: report of three cases and review.Respiratory syncytial virus (RSV) infection is an important cause of respiratory mortality in immunosuppressed patients, including bone marrow transplant (BMT) recipients. The presence of lower respiratory tract infection and infection in the pre-engraftment phase of BMT is believed to confer a poor prognosis. Three patients who underwent allogeneic BMT at our institution developed RSV pneumonia over 1 year post BMT, with the underlying disease in remission. All three were hypoxic with extensive pulmonary disease at presentation. Treatment consisted of aerosolized ribavirin and intravenous immune globulin with successful clearing of viral shedding and excellent clinical outcomes. RSV infection is probably less severe in the late post-BMT period, but needs to be considered early in the differential diagnosis of pulmonary infiltrates in this patient population.- - - - - - - - - - ranking = 0.045079113716395keywords = pneumonia (Clic here for more details about this article) |
9/38. DNase treatment for atelectasis in infants with severe respiratory syncytial virus bronchiolitis.respiratory insufficiency due to respiratory syncytial virus (RSV) bronchiolitis is partly due to the abundance of thickened mucus and the inability to clear it from the airways. mucus in RSV bronchiolitis contains necrotic inflammatory and epithelial cells. The viscoelastic properties of purulent airway secretions are largely due to the presence of highly polymerized deoxyribonucleic acid (dna). Recombinant human deoxyribonuclease (rhDNase) is known to liquefy such mucus in patients with cystic fibrosis, whereas case reports described a beneficial effect in other respiratory disorders. The authors hypothesized that rhDNase would diminish atelectasis and mucus plugging in infants with severe RSV bronchiolitis. Two infants with RSV bronchiolitis with massive unilateral atelectasis in whom mechanical ventilation was imminent due to exhaustion, and three mechanically ventilated infants (two neonates, one with bronchopulmonary dysplasia) with RSV bronchiolitis with pneumonia received treatment with 2.5 mg nebulized rhDNase twice daily. Following administration of nebulized recombinant human deoxyribonuclease, clinical and radiological parameters improved quickly. Mechanical ventilation could be avoided in two infants while in three infants on artificial ventilation, clinical recovery started following the first dose of the drug. A therapeutic trial of recombinant human deoxyribonuclease may be an option in the treatment for atelectasis in severe or complicated respiratory syncytial virus bronchiolitis in infancy.- - - - - - - - - - ranking = 10.045079113716keywords = bronchiolitis, pneumonia (Clic here for more details about this article) |
10/38. Severe respiratory syncytial virus pneumonia associated with primary Epstein-Barr virus infection.This is a case report of a child with severe respiratory syncytial virus (RSV) pneumonia and concurrent infection with Epstein-Barr virus. We hypothesize that immunosuppression due to EBV may have contributed to the severity of his RSV infection. The diagnosis of RSV infection was facilitated by bronchoalveolar lavage.- - - - - - - - - - ranking = 0.22539556858198keywords = pneumonia (Clic here for more details about this article) |
