Two antigens cross-reactive with carc inoembryonic antigen (CEA) and distinct from the nonspecif ic cross-react ing antigen were identified in meconium by double immunodiffusion with a conventional goat ant i -CEA antiserum. These two antigens together competi t ively inhibited cross-react ing antibodies against them in CEA radioimmunoassay and contr ibuted to the measurement of meconium CEA le...

OBJECTIVE Congenital cytomegalovirus (CMV) infection is a leading cause of hearing loss and mental retardation throughout the world. Detection of the CMV DNA by polymerase chain reaction (PCR) offers a sensitive, rapid, and specific means of identification. Meconium, the stool formed in utero, may be an ideal specimen for CMV detection. The objective of this study was to develop a PCR-based met...

OBJECTIVE This study was to determine the significance of meconium in the amniotic fluid of pregnancies complicated by preterm premature rupture of membranes (PPROM) without labor. METHODS A case-control study of 31 pregnancies complicated by PPROM at 27-36 weeks gestation with meconium present (study group) and 93 pregnancies complicated by PPROM but without meconium was performed. The patie...

Meconium aspiration syndrome is a cause of significant morbidity and mortality in the perinatal period and has been implicated in the pathogenesis of airway dysfunction. In this study, we developed a murine model to evaluate the effects of meconium aspiration on airway physiology and lung cellular responses. Under light anesthesia, BALB/c mice received a single intratracheal instillation of mec...

The establishment and succession of bacterial communities in infants may have a profound impact in their health, but information about the composition of meconium microbiota and its evolution in hospitalized preterm infants is scarce. In this context, the objective of this work was to characterize the microbiota of meconium and fecal samples obtained during the first 3 weeks of life from 14 don...

Meconium (I), the characteristic first stool of the infant, is a viscid, sticky, odorless, greenish brown to black material, which is regularly seen during the 5th month of fetal development. The amount excreted after birth varies from 60 to 200 gm. It is generally considered to be an accumulation of debris consisting of desquamated cells of the alimentary tract and skin, lanugo, fatty material...

BACKGROUND Approximately 5 % of infants born with a meconium-stained amniotic fluid (MSAF) develop meconium aspiration syndrome (MAS). AIM The aims of this study were to analyse demographic data, morbidity and mortality associated with MAS and to identify possible risk factors. METHODS Retrospective chart review of newborns with MAS delivered at a tertiary centre from January 1st, 1997 to D...
