1/5. Neurologic complications associated with respiratory syncytial virus.Encephalopathy has been demonstrated to be associated with respiratory syncytial virus bronchiolitis. In this study, the data on all patients less than 14 years of age hospitalized with respiratory syncytial virus bronchiolitis over the past 4 years was reviewed. patients who had concomitant diagnoses consistent with neurologic disease underwent detailed chart review. There were 964 patients (age 0.1 to 13.6 years) with a diagnosis of respiratory syncytial virus bronchiolitis. Thirty-six of these patients had concurrent neurologic diagnoses. Twenty-four patients were excluded because of preexistent neurologic disorders, probable simple febrile seizures, or a history of epilepsy. Twelve respiratory syncytial virus-positive patients had definite neurologic complications without another recognized cause. Seven of these patients had seizures (predominantly generalized tonic-clonic and one with status epilepticus), three had generalized encephalopathy (marked hypotonia and decreased responsiveness) of whom two also developed esotropia. Two patients developed isolated esotropia. There was an incidence of neurologic complications of 1.2% (0.7% seizures) in a total of 964 patients with respiratory syncytial virus bronchiolitis. This percentage does not include presumed simple febrile seizures or exacerbations of preexisting seizure disorder (further 1.3%). Neurologic complications occur with respiratory syncytial virus bronchiolitis, and physicians and other caregivers should be aware of this entity as well as the favorable prognosis.- - - - - - - - - - ranking = 1keywords = respiratory syncytial virus, syncytial virus, virus (Clic here for more details about this article) |
2/5. Respiratory syncytial virus and supraventricular tachycardia in an infant.A 7-week infant admitted with bronchiolitis proven to be caused by respiratory syncytial virus developed a supraventricular tachycardia which responded to digitalization. She has remained well and no longer requires medication 6 months later, her electrocardiogram now being normal. The course of the illness suggests an association between infection with respiratory syncytial virus and the development of the tachycardia.- - - - - - - - - - ranking = 0.32705440550272keywords = respiratory syncytial virus, syncytial virus, virus (Clic here for more details about this article) |
3/5. Infections due to parainfluenza virus type 4 in children.Parainfluenza viruses are a major cause of hospitalization for respiratory illness in children. The spectrum of clinical illness associated with infection due to parainfluenza type 4 virus has not been well defined. It is technically difficult to isolate the virus in tissue culture, and because illness is generally reported to be mild, in many cases, patients may not seek medical attention. We describe a series of 10 children with parainfluenza type 4 virus infection who were seen at the Montreal Children's Hospital between 1988 and 1992. There were five males and five females whose average age was 29.7 months. infection was associated with symptoms of bronchiolitis or pneumonia in 5 children, paroxysmal coughing in 3 infants, apnea in 1 newborn, and aseptic meningitis in 1 child. hospitalization was required for 8 of the 10 children. It appears that infection with parainfluenza type 4 virus may be more common than previously recognized, and it may be associated with more severe infections.- - - - - - - - - - ranking = 3.3456323116755E-5keywords = virus (Clic here for more details about this article) |
4/5. Human T-cell lymphotropic virus type I (HTLV-I) carrier with clinical manifestations characteristic of diffuse panbronchiolitis.A 45-year-old male was referred due to prolonged productive cough. Despite the fact that bronchoalveolar lavage fluid suggested lymphocytic and neutrophilic alveolitis, the histologic diagnosis of his biopsied lung was diffuse panbronchiolitis-like lesion with infiltration of lymphocytes and plasma cells into respiratory bronchioles but few foamy cells. Serologic examination revealed that he was a carrier of human T-cell lymphotropic virus type I (HTLV-I). Together with uveitis and ulcerative colitis in his past history, the persistent respiratory symptoms of this patient can be attributed to non-neoplastic inflammation due to the chronic HTLV-I infection.- - - - - - - - - - ranking = 1.8586846175975E-5keywords = virus (Clic here for more details about this article) |
5/5. Ventricular arrhythmia associated with respiratory syncytial viral infection.Respiratory syncytial virus (RSV) is a common cause of lower respiratory infections in infants. Cardiac arrhythmias are an uncommon complication in infants with RSV bronchiolitis. Presumably, the arrhythmias may be secondary to RSV pericarditis, myocarditis, or some other infection of the heart. We report on a patient with RSV bronchiolitis who had clinical myocarditis complicated by ventricular tachycardia.- - - - - - - - - - ranking = 0.026208252340638keywords = syncytial virus, virus (Clic here for more details about this article) |
