D-Penicillamine for preventing retinopathy of prematurity in preterm infants.

BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: To answer the question: Among very low birth weight infants, what is the effect of prophylactic administration of d-penicillamine on the incidence of acute ROP or severe ROP, and side effects including death? SEARCH STRATEGY: Searches were made of multiple electronic databases, previous reviews including cross references, abstracts, conference/symposia proceedings, and expert informants. SELECTION CRITERIA: Randomized or quasi-randomized controlled trials that administered d-penicillamine to infants less than 2000g birth weight within the day following birth were considered relevant to this review. Additional case series were examined for potential side effects. DATA COLLECTION AND ANALYSIS: Data on clinical outcomes were excerpted by 3 reviewers independently, and consensus reached. Data analysis was conducted according to the standards of the Neonatal Cochrane Review Group. MAIN RESULTS: Two randomized trials on the effects on ROP were identified. When combined, they showed a significantly lower incidence of acute ROP in the treated infants, relative risk of 0.09, 95% CI [0.01,0.71]. Severe stages of ROP could not be analyzed. There was no effect on death rates, relative risk 0.99 95% CI [0.70,1.39]. No side effects were reported, and follow up at one year revealed no significant differences in spasticity or developmental delay, although there were more rehospitalizations among the controls. In other reports of using d-penicillamine in over 140 infants for hyperbilirubinemia, skin rashes were reported in 2 infants and one had vomiting that may have been related. REVIEWER'S CONCLUSIONS: D-penicillamine is unlikely to affect survival, and may reduce the incidence of acute ROP among survivors. Studies to date justify further investigation of this drug in a broader population; careful attention to possible side effects is needed.

Incidence and significance of primary abnormalities of cardiac rhythm in infants at high risk for sudden infant death syndrome.

The exact relationship between cardiac arrhythmias and sudden infant death syndrome (SIDS) is uncertain. Several reports have implicated both ventricular and supraventricular arrhythmias in isolated cases, but there have been no studies of the incidence or type of arrhythmias that occur in populations at risk for SIDS. Of 1699 infants at high risk for SIDS, 60 (4%) were found to have a primary cardiac arrhythmia (i.e., not associated with disordered respiration or apnea). The incidence of atrial and ventricular premature beats, supraventricular tachycardia, and Wolff-Parkinson-White syndrome was similar to the incidence found in normal infants. Primary bradycardia (defined as a heart rate less than 60 for greater than 10 s not associated with abnormal respiration) was the most common arrhythmia, occurring with a frequency and severity not seen in normal infants. Thirty-two infants experienced periodic bradycardia. In 19 of these latter infants, there were symptoms associated with these bradyarrhythmias that necessitated treatment. Heart rates as low as 20 beats/min were recorded. One infant presented with an episode of ventricular fibrillation and on further evaluation was noted to have recurrent bradyarrhythmias. In no infant was there abnormal prolongation of the QT interval. Primary bradyarrhythmias are seen at an increased incidence in infants at high risk for SIDS and may play a causal role in this syndrome. Most symptomatic infants can be adequately controlled with sympathomimetic or parasympatholytic therapy. Other cardiac arrhythmias occur at a rate similar to that in normal infants and are therefore unlikely to play a major role in SIDS.

Growth, developmental milestones and health problems in the first 2 years in very preterm infants compared with term infants: a population based study.

UNLABELLED: The outcome of very preterm infants varies widely from centre to centre and from country to country. The aim of this study was to evaluate growth, developmental milestones and post-discharge morbidity of infants born before 32 weeks of gestation in Switzerland. A questionnaire was sent to the parents of 456 survivors born in 1996. A total of 309 (68%) parents responded and their infants were matched with 309 control infants born at term. At the corrected age of 24 months, the very preterm infants had significantly lower weight (-1.0 z-scores), lower length (-1.23 z-scores), and lower head circumference (-.64 z-scores). Very preterm infants were reported to eat with a spoon later than those born at term (50% at 7.5 months corrected for prematurity versus 10 months. P<0.001), to drink later out of a cup (50% at 16.5 months versus 13.5 months, P=0.03) and to walk later independently (50% at 14.5 months versus 13.5 months, P=0.04), whereas timing of sitting unsupported was no different (50% at 7.4 months versus 7.2 months, P=0.9). Of very preterm infants, 16% were not able to walk at least three steps unsupported at 18 months after term which puts them at an increased risk for cerebral palsy. Some 35% of very preterm infants had to be readmitted to hospital during the first 24 months compared with 20% of control infants born at term (P<0.05). There was no difference between very preterm and term infants in respect to episodes of fever > 38.5 degrees C, episodes of coughing > 3 days and treatment with antibiotics. CONCLUSION: these data based on a national survey allow to quantify growth retardation, developmental delay and post-discharge health problems within the first 2 years in preterm infants born before 32(0)/7 weeks.

Effects of infant and caregiving conditions on an infant's focused exploration of toys.

An infant's exploration of toys, in the context of the mother's regulating actions, is a setting for cognitive and social development. The aim of this study was to examine the contribution of infant and caregiving conditions to the quantity of focused exploration of toys for 8-month-old infants. Infant biological conditions were gender and birth weight, including a range of both prematurely and term-born infants. The infant behavioural condition was responsiveness to care. Caregiving conditions included mother's education, the supportive, stimulating and sustaining quality of the home environment, and the attention-directing and -supporting behaviour of the mother during play. The direct and indirect effects of these conditions on focused toy exploration were modelled using multiple regression. The sample of 79 mother-infant dyads included 43 full-term infants and 36 premature infants. The mother's attention-directing behaviour was a significant negative predictor of focused toy exploration. Infant birth weight did not have a significant direct effect on focused toy exploration. Birth weight did not interact significantly with responsiveness to care or with any of the caregiving environment conditions to affect focused toy exploration. Further study of infant responses to the mother's attention-regulating and emotion-regulating behaviour during play is recommended to better understand how the caregiving environment supports or thwarts focused toy exploration.

Evaluation of test-weighing for the assessment of milk volume intake of formula-fed infants and its application to breast-fed infants.

Test-weighing (TW) was evaluated in formula-fed (FF) infants by comparison with direct measurement (DM) of formula intake during a 24 h period at 1, 2, 4 and 6 mo of age. Formula intakes estimated by TW ranged from 87 to 93% of those determined by DM over the 6-mo period. During the study period the number of feedings per day decreased but were not significantly different for FF and BF infants. Volume of intake per feeding by FF infants increased significantly during the 6-mo period whereas milk intakes of BF infants were not different at the four ages studied. These data indicated that when the number of daily feedings decreased with age, FF infants increased their volume of intake per feeding whereas BF infants did not adjust their intakes. Mean volume of milk intake at 4 and 6 mo, estimated by TW, was significantly greater in FF infants compared to breast-fed (BF) infants matched for age and size. Data from this study indicated clearly that when milk intakes of BF infants are compared to those of FF infants, both groups of infants should be test-weighed.

Parenting stress in mothers of very-low-birth-weight (VLBW) and full-term infants: a function of infant behavioral characteristics and child-rearing attitudes.

OBJECTIVE: To examine the moderating effects of child-rearing attitudes on the relation between parenting stress and infant behavioral characteristics for mothers of very-low-birth-weight (VLBW) and full-term infants. METHODS: Fifty-six 9-month-old infants (23 VLBW and 33 full-term) and their mothers were the participants. Mothers completed measures of parenting stress, child-rearing attitudes, infant temperament, and infant behavioral problems. RESULTS: The VLBW infants had a higher frequency of behavioral problems, and their mothers reported more child health concerns than the mothers of the full-term infants. Regression analyses showed that the relation between parenting stress and infant distress was moderated at medium and high levels of parental strictness for only the VLBW infants. CONCLUSIONS: The amount of stress the mothers of the VLBW infants experienced was a result of the congruence between their infant's behavioral characteristics and their own child-rearing attitudes.

Quantitative real-time PCR analysis of fecal Lactobacillus species in infants receiving a prebiotic infant formula.

The developing intestinal microbiota of breast-fed infants is considered to play an important role in the priming of the infants' mucosal and systemic immunity. Generally, Bifidobacterium and Lactobacillus predominate the microbiota of breast-fed infants. In intervention trials it has been shown that lactobacilli can exert beneficial effects on, for example, diarrhea and atopy. However, the Lactobacillus species distribution in breast-fed or formula-fed infants has not yet been determined in great detail. For accurate enumeration of different lactobacilli, duplex 5' nuclease assays, targeted on rRNA intergenic spacer regions, were developed for Lactobacillus acidophilus, Lactobacillus casei, Lactobacillus delbrueckii, Lactobacillus fermentum, Lactobacillus paracasei, Lactobacillus plantarum, Lactobacillus reuteri, and Lactobacillus rhamnosus. The designed and validated assays were used to determine the amounts of different Lactobacillus species in fecal samples of infants receiving a standard formula (SF) or a standard formula supplemented with galacto- and fructo-oligosaccharides in a 9:1 ratio (OSF). A breast-fed group (BF) was studied in parallel as a reference. During the 6-week intervention period a significant increase was shown in total percentage of fecal lactobacilli in the BF group (0.8% +/- 0.3% versus 4.1% +/- 1.5%) and the OSF group (0.8% +/- 0.3% versus 4.4% +/- 1.4%). The Lactobacillus species distribution in the OSF group was comparable to breast-fed infants, with relatively high levels of L. acidophilus, L. paracasei, and L. casei. The SF-fed infants, on the other hand, contained more L. delbrueckii and less L. paracasei compared to breast-fed infants and OSF-fed infants. An infant milk formula containing a specific mixture of prebiotics is able to induce a microbiota that closely resembles the microbiota of BF infants.

Colic in breast-milk-fed infants: treatment by temporary substitution of neocate infant formula.

Infant colic is a common problem characterized by excessive crying and fussing. We examined whether colic symptoms of exclusively breast-milk-fed infants would be improved by temporary substitution of Neocate, an amino acid-based infant formula, for breast milk. Six infants with colic were studied using Barr-type infant behavior diaries for a 3-5 d baseline period while they continued exclusive breast-milk-feeding, followed by a 4-8 d intervention period of exclusive Neocate feeding. All infants showed improvement in distressed behavior during intervention; five of the six improved within 1-2 d. For the period after 1 d of Neocate feeding, the total recorded crying and fussing time was reduced by an average of 42%, representing a decrease of 1.0 to 3.1 h daily. A significant difference was found between cry and fuss time at baseline versus during exclusive Neocate use. Concurrent with Neocate intervention, mothers strictly avoided all milk and dairy products. After colic symptoms improved, infants were reintroduced to breast milk, which was reasonably well tolerated in four of the six infants. Two infants had rapid recurrences of crying and fussing upon return to breastfeeding and required an additional period of Neocate feedings before subsequent reintroduction to breastfeeding. All infants exhibited colic symptoms when directly or indirectly challenged with bovine IgG (BGG), suggesting that BGG may play an etiologic role in colic. We propose that a brief intervention with Neocate, coupled with strict maternal avoidance of milk and dairy products under direct supervision of a lactation consultant, may be an effective treatment for colic in some breast-milk-fed infants.

[Tear production in premature infants, newborn infants and infants].

These investigations concerned 50 babies at the age of 34 to 47 weeks and two days. After local instillation of anesthetic drops, Schirmer-1-test was done. The average basal tear production was 5 mm +/- 3 mm in 5 minutes. This result was independent of absolute age of the babies, of birth weight, of the degree of maturity and of sex; there was no significant difference between right or left side.
