[Ibuprofen versus indomethacin in the treatment of patent ductus arteriosus in preterm infants].

INTRODUCTION: Persistent patent ductus arteriosus (PDA) is a common entity in preterm infants. The most commonly used pharmacological treatment to close the ductus is indomethacin but it can affect cerebral, renal and mesenteric blood flow. Ibuprofen has recently been shown to be effective in closing PDA with fewer hemodynamic effects. In this study we compared the safety and efficacy of ibuprofen and indomethacin in the treatment of PDA in preterm infants. MATERIAL AND METHODS: A randomized trial was performed. Premature infants with symptomatic PDA confirmed by echocardiography in the first week of life and who required respiratory support were included. The patients were randomly assigned to receive either intravenous indomethacin or ibuprofen. The rate of ductal closure, need for additional treatment, complications, and clinical course were evaluated. RESULTS: Twenty-four patients were treated with indomethacin and 23 with ibuprofen. The clinical characteristics before treatment were similar in both groups. Both treatments were effective in closing PDA (87.5% in the indomethacin group and 82.6% in the ibuprofen group). The two cohorts did not differ in the rate of reopening, need for a second pharmacologic treatment, or surgical ductal ligation. No patient in the ibuprofen group developed gastrointestinal adverse effects, but two infants in the indomethacin group had isolated bowel perforation and one had necrotizing enterocolitis. Transient renal dysfunction developed in seven patients (29%) in the indomethacin group versus two (9%) in the ibuprofen group. Transient renal insufficiency was found in one patient in the indomethacin group and in none in the ibuprofen group. The rate of other complications was similar in both groups. CONCLUSIONS: In our trial ibuprofen was as effective as indomethacin in closing PDA. No significant differences were found in the incidence of complications but fewer renal complications and no gastrointestinal complications were found in the ibuprofen group.

[Palliative arterial switch].

We report the first case published in Spain of a palliative anatomic correction associated with aortic arch repair in a neonate with (S,D,L)-transposition of the great arteries, multiple ventricular septal defects, and severe hypoplasia of the right ventricle with subaortic obstruction and hypoplasic aortic arch with coarctation. A one stage palliative surgery on cardiopulmonary bypass was performed with reconstruction of the aortic arch and an arterial switch procedure which obtained a satisfactory result. The principle of this operation is to switch the subaortic obstruction into a subpulmonary obstruction and reconstruct a large natural aortic root from the principal ventricle. The right ventricle-pulmonary artery continuity may promote growth of the right ventricle with the possibility of a future biventricular repair. We conclude that this operation, when used by surgical teams experienced with arterial switch surgery, is the best treatment for the complex newborn group with single ventricles or severe ventricular disbalance, ventriculoarterial discordance and stablished subaortic stenosis.

[Scimitar syndrome: series of 12 cases].

Our experience in 12 cases of pediatric patients with scimitar syndrome is reported. Except for one, all of them presented cardiac or respiratory manifestations. The symptomatology was related to associated defects (3 atrial septal defects and 1 multiple peripheric pulmonary stenosis), degree of pulmonary hypoplasia, size of the right to left shunt and pulmonary hypertension. 3 patients underwent surgical treatment. One of them died during operation and the other two have had a good evolution. Nine patients with later respiratory manifestations have improved their condition progressively without surgical intervention. Therapeutic approach for patients with scimitar syndrome, respiratory manifestations and onset beyond the neonatal period, should be conservative.

[Repercussion of risk factors associated with the development of chronic bronchial pathology on pulmonary function in children].

Of a total of 1,566 children, 1,416 of both sexes and aged 7 to 14 were subjected to functional respiratory exploration with a Vitalograph dry spirometer. The impact of tobacco smoke--as active and/or passive smokers--on the spirometric variables (FVC, FEV1, FEF2572, FEF50) evaluated by variance analysis (ANOVA) revealed no significant reductions. Asthma was the single antecedent of respiratory morbidity showing significant reductions in FEF2575, FEF50 among males alone; no significant reductions were observed for any of the other spirometric variables. No significant decreases were found in the spirometric variables on comparing two areas of the same city with the greatest difference in air pollution level.

[Exercise test in exercise-induced asthma in children: study of delayed response].

In this study we perform the exercise broncho-provocation test according to a protocol and involving 27 children with allergic asthma to study the prevalence and distinctive traits of the late response in exercise-induced asthma (EIA). At the conclusion of the study, 20 patients (74%) were diagnosed of EIA through some of the tests employed (ergometric bicycle, free run). In the cases where both tests were negative, we reproduced in a controlled manner the exercise reported as asthmogenic on the basis of anamnesis; no positivity was observed for the test in any case. Prevalence of late asthmatic response was 40% (8/20); mean beginning time to this response was 4-6 hours, lasting less than 1 hour and with a mean intensity rate of 26.8% (measured as the percentage of PEFR drop according to the preexercise basal value). The results are discussed, comparing them with those of other authors and with the allergen provocation response pattern; in addition the methods used and therapeutic implications in view of the results are dealt with.

[Basal pulmonary function studies (FVC, FEV) in a selected child population].

This is a study of the ventilatory function (FVC, FEV1) by dry spirometer Vitalograph in 1566 children of both sexes with ages ranging from 7 to 14; 1156 children (73.6 per 100) were selected as reference population. Height was the biometric parameter with the greatest correlation to the functional variables studied in both sexes. Significant differences were observed in functional variables between male and female subjects. Multiple and simple linear prediction equations and percentiles tables for each sex are presented. The results of the present study are compared with those of previously published of children.
