Excess mortality and morbidity among small-for-gestational-age premature infants: a population-based study.

OBJECTIVE: We examined the effect of intrauterine growth restriction on mortality and morbidity in the Israel cohort of very low birth weight premature infants. METHODS: The study population included 2764 singleton very low birth weight infants without congenital malformations born from 24 to 31 weeks of gestation during 1995 to 1999. Four hundred six (15%) were born small for gestational age (SGA). The effect of SGA on death, bronchopulmonary dysplasia, and retinopathy of prematurity was assessed using multiple logistic regression analysis. RESULTS: After adjustment for perinatal risk factors, SGA infants had a 4.52-fold risk for death (95% CI, 3.24-6.33), a 3.42-fold risk for bronchopulmonary dysplasia (95% CI, 2.29-5.13), and a 2.06-fold risk for grade 3 to 4 retinopathy of prematurity (95% CI, 1.15-3.66). CONCLUSIONS: SGA premature infants had an increased risk for death, and major morbidity among survivors was increased.

Early physical activity intervention prevents decrease of bone strength in very low birth weight infants.

OBJECTIVE: To evaluate the effect of early range-of-motion intervention on bone strength and bone turnover in very low birth weight infants. METHODS: Twenty-four infants (mean birth weight: 1135 +/- 247 g; mean gestational age: 28.5 +/- 2.3 weeks) were matched for gestational age and birth weight and then randomly assigned into exercise (n = 12) and control (n = 12) groups. Exercise protocol started at the first week of life and involved daily extension and flexion range of motion against passive resistance of the upper and lower extremities (5 minutes per day, 5 days per week, 4 weeks). Growth parameters, bone strength, and biochemical markers of bone homeostasis were measured at enrollment and after 4 weeks. Bone strength was determined using quantitative ultrasound measurement of bone speed of sound (SOS) at the middle left tibial shaft. RESULTS: Bone SOS decreased significantly in the control group during the study period (from 2892 +/- 30 m/sec to 2799 +/- 26), whereas bone SOS of the exercise group remained stable (2825 +/- 32 m/sec and 2827 +/- 26 m/sec at baseline and 4 weeks, respectively). This significant difference in bone SOS was not expressed in the biochemical markers of bone homeostasis. CONCLUSIONS: There is a significant postnatal decrease in the bone SOS of very low birth weight infants. A brief range-of-motion exercise attenuates the decrease in bone strength and may decrease the risk of osteopenia.

Severe Coxsackie virus B infection in preterm newborns treated with pleconaril.

UNLABELLED: Four preterm newborn infants with severe multisystem Coxsackie virus B infection were treated with an oral suspension of pleconaril (5 mg/kg per day). The patients had myocarditis, fulminant hepatitis, meningoencephalitis and disseminated intravascular coagulopathy. All four infants recovered, and no adverse effects of the treatment were noted. CONCLUSION: pleconaril needs to be comprehensively evaluated in this population.

Serum amyloid A protein in the early detection of late-onset bacterial sepsis in preterm infants.

In order to evaluate serum amyloid A as an early diagnostic marker of late-onset sepsis, seventy-nine preterm infants with clinically suspected sepsis and 40 healthy matched controls were assayed for serum amyloid A. In parallel, clinical and biochemical variables that are used to evaluate neonatal sepsis were compared. Forty-two episodes were diagnosed as sepsis. Serum amyloid A levels were elevated in the sepsis group (187.6 +/- 78.3 micrograms/ml), compared with infants who had no sepsis (10.2 +/- 8.3 micrograms/ml) and the control group (6.9 +/- 3.3 micrograms/ml), and were significantly higher in gram-negative compared to gram-positive sepsis (221.8 +/- 84.4 micrograms/ml vs. 48.5 +/- 22.2 micrograms/ml). Analysis of the data suggests serum amyloid A has the highest sensitivity (100%), specificity (93%) and positive predictive value (96%) for sepsis among the clinical and biochemical parameters that were tested. In conclusion, serum amyloid A seems to be a reliable early marker for the diagnosis of late-onset sepsis in preterm infants.
