Randomized Controlled Trial Multicenter Study Clinical Trial
A randomized, double-blind, placebo-controlled trial of the effects of prophylactic theophylline on renal function in term neonates with perinatal asphyxia.
The kidney is the most damaged organ in asphyxiated full-term infants. Experiments in rabbits and rats have shown that renal adenosine acts as a vasoconstrictive metabolite in the kidney after hypoxemia and/or ischemia, contributing to the fall in glomerular filtration rate (GFR) and filtration fraction. Vasoconstriction produced by adenosine can be inhibited by the nonspecific adenosine receptor antagonist, theophylline. Gouyon and Guignard performed studies in newborn and adult rabbits subjected to normocapnic hypoxemia. Their results clearly showed that the hypoxemia-induced drop in GFR could be avoided by the administration of low doses of theophylline. ⋯ Our data suggest that prophylactic theophylline, given early after birth, has beneficial effects on reducing the renal dysfunction in asphyxiated full-term infants.

Randomized Controlled Trial Multicenter Study Clinical Trial
Effect of infection control measures on the frequency of upper respiratory infection in child care: a randomized, controlled trial.
Acute upper respiratory infections are common in children who attend child care, and preventing transmission of disease in this setting depends on actions by child care staff. We set out to discover whether transmission of respiratory infections in child care could be reduced by improved infection control procedures. ⋯ This trial supports the role of direct transmission of colds in young children in child care. The ability of infection control techniques to reduce episodes of colds in children in child care was limited to children 24 months of age and under.

Although the equimolecular mixture of oxygen and nitrous oxide (EMONO) seems a good choice to relieve procedure-related pain in children, it has not been accepted everywhere. In France, the rapid spread of its use has elicited suspicion and doubts regarding its safety. To assess the use and the safety of this gas mixture in the pediatric settings in France, we conducted a national survey. ⋯ One thousand nineteen EMONO inhalations from 31 centers that agreed to participate in this 2-month survey were analyzed. Median (range) age was 6.4 (0-18) years. Four percent (46) of children were 12 months old or younger, 29% (295) were 5 years old or younger, 45% (459) were 6 to 10 years old, and 26% (265) were older than 10 years of age. The procedures performed with EMONO inhalation were: lumbar punctures (286), bone marrow aspirations (BMA; 231), laceration repairs (215), minor procedures (75), minor surgery (53), punctures (49), fractures (45), dental care (43), and pulmonary endoscopy (22). Nine percent of procedures were undertaken without the presence of a physician; the child being observed only by the attending nurse. A drug association was noted in 182 (17.9%) of procedures: midazolam (63%), acetaminophen (18%), nalbuphine (8.5%), hydroxyzine (5%), flunitrazepam (2%), chlorazepate (2%), morphine (1%), and lorazepam (.5%). EMLA cream (Astra) was applied in 98.6% of lumbar punctures, 93.7% of BMA, and 54.2% of punctures including lymph nodes, hematoma, or renal biopsies. Lidocaine infiltration was performed in 51% of minor surgery procedures, 40% of laceration repairs, and 28% of BMA. The inhalation system included a whistle, a scented mask, and a nonrebreathing respiratory valve in 48.9%, 71.2%, and 78.3% of the patients, respectively. Initial physical restraint was needed in 18. 2% of all the patients. Inhalation refusal was noted in 129 (12.7%) children; of these, 53 had an alternative method of analgesia (EMLA or lidocaine infiltration), 15 had no other analgesia, and in the remaining 61, EMONO inhalation was maintained against the child's will. Median (interquartile) inhalation length was 4 (3-5) minutes before starting the procedure and 6 (6-15) minutes for the total inhalation. Median (interquartile) procedural pain evaluations were 9 (0-30) for children on a 0 to 100 visual analog scale, 1 (0-3) for both nurses and parents on a 0 to 10 numerical scale. Median (interquartile) procedural pain as evaluated by nurses for the 3 most frequent procedures were 0 (0-2) for lumbar punctures, 2 (0-4) for bone marrow aspiration, and 2 (0-4) for laceration repair. Comparison of pain assessed by nurses in children 3 years old or younger and those older than 3 years of age showed a median (range) score of 2 (0-10) versus 1 (0-10), respectively. Pain self-assessment was completed in 647 children 6 years of age or older. Median (interquartile) children pain assessments were as follows: lumbar puncture (5; 0-20), bone marrow aspiration (12.5; 0-40), laceration repair (12; 0-40), minor procedures (18; 0-32), minor surgery (10; 0-35), punctures (0; 0-18), fracture (15; 0-30), dental care (20; 0-40), and pulmonary endoscopy (15; 0-30). Ninety-three percent of the 647 children who were able to answer the question said they would accept EMONO analgesia if a new procedure were to be performed. Behavioral reactions during procedures varied with age of the child; cry was observed in 44.1%, 24.4%, 12.9%, and 11.2% of children 3 years or younger, 4 to 6 years, 7 to 10 years, and 11 years or older, respectively. Physical restraint was necessary in 34.2%, 22%, 13.5%, and 8.4% of children aged 3 years or younger, 4 to 6 years, 7 to 10 years, and 11 years or old

Reference data are lacking on the frequency and duration of assisted ventilation in neonates. This information is essential for determining resource needs and planning clinical trials. As mortality becomes uncommon, ventilator utilization is increasingly used as a measure for assessing therapeutic effect and quality of care in intensive care medicine. Valid comparisons require adjustments for differences in a patient's baseline risk for assisted ventilation and prolonged ventilator support. The aims of this study were to determine the frequency and length of ventilation (LOV) in preterm and term infants and to develop models for predicting the need for assisted ventilation and length of ventilator support. ⋯ Considerable variation exists in the utilization of ventilator support among infants of closely related gestational age. In addition, a number of medical risk factors influence the need for, and length of, assisted ventilation. These models explain much of the variance in LOV among preterm infants but explain substantially less among term infants.neonatal intensive care, assisted ventilation, Score for Neonatal Acute Physiology, resource consumption, prematurity.

Comparative Study
Primary care role in the management of childhood depression: a comparison of pediatricians and family physicians.
To provide a self-described assessment of pediatricians' and family physicians' management of childhood depression. ⋯ Most primary care physicians refer pediatric patients with depression; however, practice patterns vary by specialty and other factors. Future studies must consider the role of primary care and evaluate how interspecialty variations affect costs and outcomes of childhood depression.
