BACKGROUND We studied the contribution of elective delivery to severe respiratory distress syndrome (RDS) in term babies born at high altitude. METHODS We prospectively studied the charts of term babies born in Taif Maternity Hospital (1640 m above sea level) between 1/1/2004 and 31/10/2004 who developed RDS and required mechanical ventilation. RESULTS 8634 deliveries occurred from 37-<41 w...
The etiology of respiratory distress syndrome (RDS) is multifactorial and multigenic. Studies have suggested that polymorphisms and mutations in the surfactant protein B (SP-B) gene are associated with the pathogenesis of RDS. The objectives of this study were to determine and compare the frequencies of SP-B gene polymorphisms in preterm babies with and without RDS. We studied 151 neonates: 79 ...
A phospholipid profile, the main features of which were the lecithin/sphingomyelin (L/S) ratio and the presence or absence of phosphatidylglycerol (PG), was determined in amniotic fluid from 188 patients. There was a mature profile (L/S ratio of at least 2 . 0 and detectable PG) in 145 patients, including seven insulin-dependent diabetics, and noe of their babies developed respiratory distress ...
Polymorphisms and mutations in the surfactant protein B (SP-B) gene have been associated with the pathogenesis of respiratory distress syndrome (RDS). The objective of the present study was to compare the frequencies of SP-B gene polymorphisms between preterm babies with RDS and healthy term newborns. We studied 50 preterm babies with RDS (inclusion criteria - newborns with RDS and gestational ...
The results are reported of a multicenter randomized study of the effectiveness of maternal administration of betamethasone versus ambroxol, a substance of the group of the benzylamines, for prevention of RDS in preterm infants. Women of 27 to 34 weeks gestation with threatened premature delivery or planned premature delivery were admitted to the trial. Between September 1981 and November 1984 ...
AIM Respiratory distress syndrome (RDS) is a major cause of mortality and morbidity in premature infants. By the time symptoms appear, it may already be too late to prevent a severe course, with bronchopulmonary dysplasia or mortality. We aimed to develop a rapid test of lung maturity for targeting surfactant supplementation. METHODS Concentrations of the most surface-active lung phospholipid...
Streptococcus suis is an important zoonotic pathogen that can cause meningitis and sepsis in both pigs and humans. Infections in humans have been sporadic worldwide but two severe outbreaks occurred in China in recent years, while infections in pigs are a major problem in the swine industry. Some S. suis strains are more pathogenic than others with 2 sequence types (ST), ST1 and ST7, being well...
Main indications for antenatal administration glucocorticoid to pregnant women are premature contractions, hemorrhage during pregnancy, conditions of fetal distress and maternal diseases. There are some absolute or relative contraindications as well: severe forms of preeclampsia, diabetes mellitus, premature rupture of membranes, maternal and/intrauterine infections. In a retrospective evaluati...
BACKGROUND Lung fibrosis is thought to be important in chronic lung disease of prematurity (CLD). METHODS Fibroblast proliferative activity was assessed in 207 bronchoalveolar lavage fluid (BALF) samples from 43 infants. Sixteen developed CLD (birth weight 765 g (630-1230), gestation 26.5 weeks (23-29)), 18 developed respiratory distress syndrome (RDS) (birth weight 1415 g (430-4160), gestati...
