1/4. Fatal coronary artery anomaly presenting as bronchiolitis.During winter outbreaks of respiratory syncytial virus bronchiolitis from 2002 to 2004, three infants presented with a presumptive diagnosis of lower respiratory tract infection and wheezing. The clinical condition in two cases was rapidly progressive and precipitated into intractable shock; clinical and instrumental examinations revealed a cardiac origin of their illness. A subacute presentation permitted a cardiological assessment and a proper treatment in the third infant. An abnormal origin of the left coronary artery from the pulmonary trunk was demonstrated in all cases. The concurrent acute airway infection had a catastrophic effect on the underlying cardiovascular anomaly leading to refractory cardiogenic shock and death. CONCLUSION: Admission chest x-ray film and arterial gas analysis can raise the suspicion of cardiac involvement when treating a severe wheezing episode in young infants. Paediatric cardiological evaluation with two-dimensional echocardiography may eventually reveal this rare condition, whereas cardiac catheterisation with aortography remains the standard means of diagnosis.- - - - - - - - - - ranking = 1keywords = respiratory tract infection, respiratory tract, tract infection, tract (Clic here for more details about this article) |
2/4. Intramural esophageal diverticulosis in an infant.In the course of evaluating an infant with recurrent episodes of bronchiolitis, the esophagus was radiologically examined. A totally unexpected finding was the presence of intramural diverticulosis of the upper part of the esophagus. On reexamination four months later, the diverticula had disappeared.- - - - - - - - - - ranking = 9.5516645037304E-6keywords = upper (Clic here for more details about this article) |
3/4. pneumothorax complicating bronchiolitis in an infant.pneumothorax is an uncommon complication of bronchiolitis. The case illustrates an unusual pattern of atelectasis of the right lung with pleural air surrounding the right upper lobe and the remainder of the lung expanded. It is thought that the hyperinflated lung is unable to collapse as a result of the 'ball valve' effect of air trapping.- - - - - - - - - - ranking = 9.5516645037304E-6keywords = upper (Clic here for more details about this article) |
4/4. Cardiac arrhythmias as a manifestation of acquired heart disease in association with paediatric respiratory syncitial virus infection.Respiratory syncitial virus (RSV) is a common cause of upper and lower respiratory tract infection in infants. An association between RSV bronchiolitis and cardiac arrhythmias has been described but is rare. A further case of an infant with supraventricular tachycardia in association with culture-positive respiratory syncitial virus bronchiolitis is reported. This case prompted a review of the two other cases of arrhythmia associated with RSV infection seen at this institution and a review of all other published cases.- - - - - - - - - - ranking = 0.99995643713497keywords = respiratory tract infection, respiratory tract, tract infection, tract, upper (Clic here for more details about this article) |
