Unlabelled: To determine the role of tracheal colonization at birth with Ureaplasma urealyticum and other pathogenic bacteria with regard to the development of bronchopulmonary dysplasia (BPD), 97 premature infants with very low birth weight (< 1500 g) were followed prospectively over 30 days in a multicentre study. Of those infants, 35 were colonized with Ureaplasma urealyticum (group Ia), 22 with other pathogenic bacteria (group Ib) and 40 infants with sterile tracheal aspirates served as controls (group II). Colonization with Ureaplasma urealyticum or with pathogenic bacteria independently increased the risk of developing BPD as compared to the controls (OR 2.55; 95% CI [1.11, 5.87]). Among Ureaplasma urealyticum and bacterial colonized infants, duration of mechanical ventilation and oxygen requirement were significantly longer than among controls (P < 0.05); during the interval of 11 to 35 days of life, every additional day of ventilation significantly increased the risk of BPD (OR 1.22; CI [1.12, 1.32]). The rate of oxygen supplementation, which was similar in both groups during the first 2 weeks of life, was significantly higher among the colonized infants at day 21 (0.38+/-0.18 and 0.39+/-0.16 vs 0.31+/-0.13, P < 0.05) and at day 28 (0.38+/-0.21 and 0.34+/-0.15 vs 0.28+/-0.12, P < 0.05). For infants still ventilated at age of 28 days, Ureaplasma urealytricum and bacterial colonization were associated with a significant higher risk for BPD than for uncolonized controls (OR 5.53; [1.27, 24.02]. Association of Ureaplasma urealyticum and of bacterial colonization and BPD was not weakened after adjustments were made in a multivariate analysis for other significant risk factors.Conclusion: Ureaplasma urealyticum colonization is as an important risk factor in the development of bronchopulmonary dysplasia as bacterial colonization even after treatment with surfactant.

Objective: To assess the bioavailability of vitamins A and E administered parenterally with either water-soluble or lipid-soluble preparations. Study design: A water soluble preparation (MVI Pediatric[sup R]) administered with a glucose-amino acid solution and a lipid soluble preparation (Vitalipid N Infant [sup R] ) infused with a lipid emulsion were subjected to phototherapy light, different flow rates, light protection, different tubing materials and tubing sizes, and concentrations in the effluents were determined. Results: Recovery of retinol in glucose-amino acid solution was poor under all conditions (16-30% without; 21-42% with light protection tubing) and increased to 61% with polyethylene and to 44% with polyurethane tubings. Polyurethane tubings with reduced volume improved retinol delivery to 56%. Retinylpalmitate (Vitalipid) losses were low, with recovery of 86 and 77% with and without light protection, respectively. Recoveries of α-tocopherylacetate in GLUC-AA were 103-107% without and 94-102% with light protection and of α-tocopherol in LIPID 89% without and 85% with light protection. Conclusions: Parenteral vitamin A delivery is improved by the infusion of retinylpalmitate with lipids. Light protecting tubings provide only a marginal benefit with artificial light and none with phototherapy light. Polyethylene and polyvinylchloride tubings adsorb less retinol than polyurethane tubings. Small tubing diameters resulting in higher flow rates enhance retinol delivery. [ABSTRACT FROM AUTHOR]

Unlabelled: Congenital sialidosis is a rare lysosomal storage disease caused by a primary neuraminidase deficiency which results from defects in the neuraminidase gene on chromosome 6p. The inheritance is autosomal recessive. Patients exhibit excessive urinary excretion of bound sialic acid and decreased or undetectable amounts of neuraminidase activity in various tissues. The clinical expression is variable, but ascites and hepatosplenomegaly are hallmarks of the disease. Skeletal abnormalities, facial dysmorphism and inguinal herniae have been described in most of the few reported cases. We describe a baby girl with biochemically proven sialidosis, who in addition to the above clinical features, had severely dilated coronary arteries, excessive retinal vascular tortuosity and an erythematous, macular rash. Homozygosity for a frameshift mutation at residue 623 of the neuraminidase cDNA was found. We speculate that the additional features found in our patient might be associated with the here described genotype of congenital sialidosis.Conclusion: Severely dilated coronary arteries, excessive retinal vascular tortuosity and an erythematous macular rash might be associated features of congenital sialidosis.

Unlabelled: The fatty acid composition of human breast milk was determined longitudinally after term and preterm delivery by high resolution gas liquid chromatography. Milk samples were obtained at days 5, 10, 20 and 30 after term (n = 38) or preterm (n = 19) delivery. The saturated fatty acids C10:0 and C12:0 and the polyunsaturates linoleic acid (C18:2 omega-6) and alpha-linolenic acid (C18:3 omega-3) increased significantly from day 5 to day 10, whereas arachidonic acid (C20:4 omega-6), total omega-6 long-chain polyunsaturates (LCP), docosahexaenoic acid (C22:6 omega 3) and total omega-3 LCP decreased significantly. Term and preterm milk did not differ in percentage content of linoleic acid, alpha-linolenic acid and LCP at any time point. Preterm milk contained significantly more medium and intermediate chain fatty acids (C10:0, C12:0 and C14:0) than term milk on days 5 (12.28 vs 9.78%; P > 0.05), 10 (16.25 vs 12.62%; P > 0.05) and 20 (17.29 vs 13.47%; P > 0.005).Conclusion: The milk of mothers of preterm infants is not better suited to meet the high LCP requirements of their infants during the first weeks after birth. The slightly higher proportion of medium and intermediate chain fatty acids in preterm milk during the 1st month after birth might be advantageous for the fat and calcium absorption of preterm infants.

The effects of Ureaplasma urealyticum colonization on pregnancy and neonatal outcome was prospectively studied in women with impending term or preterm delivery. One hundred and seventy women colonized with U. urealyticum as the only pathogenic microorganism and 83 women with negative cultures were enrolled for study. Compared to the controls, U. urealyticum colonization was associated with a significantly increased rate of amnionitis (2% vs 35%; p<0.001), chorioamnionitis (0% vs 10%; p<0.05), premature rupture of membranes (12% vs 35%; p<0.001) and preterm delivery (10% vs 41%; p<0.001). The rate of vertical transmission ranged from 38% in term infants to 95% in very low birth weight infants. U. urealyticum colonization at birth was associated with an increased risk for the development of respiratory distress syndrome (9% vs 51%), intraventricular hemorrhage (1% vs 7%) and bronchopulmonary dysplasia (4% vs 17%) in very low birth weight infants (<1500 g). It is concluded that maternal U. urealyticum colonization is associated with amnionitis, chorioamnionitis and preterm delivery, and that tracheal colonization with U. urealyticum increases the risk for respiratory and neurological complications in very low birth weight infants.

We present two premature infants with disseminated neonatal adenovirus infection, whose epidemiology, clinical course and outcome differ to a great extent. The first infant, born vaginally at 35 weeks gestational age after premature rupture of membranes and maternal illness, developed pneumonia, hepatitis and coagulopathy and died of circulatory failure at the age of 17 days. The other infant, delivered bycesarian section at 36 weeks gestational age, did - in contrast to all documented cases in the literature - not show any signs of pneumonia and survived meningitis without sequelae. The mode of transmission of the viral infection may have been via the maternal birth canal in the first infant and transplacental in the second one. Diagnosis was obtained by direct immunofluorescent test and serology in the first patient and by maternal serology and the detection of viral antigen in tracheal aspirates (ELISA) in the second patient. Disseminated neonatal adenovirus infection has a high mortality and should be considered in the differential diagnosis of neonatal sepsis, especially when pneumonia, hepatitis and neurologic symptoms develop together with thrombocytopenia or disseminated intravascular coagulopathy.
