1.  Effect of routine probiotic, Lactobacillus reuteri DSM 17938, use on rates of necrotizing enterocolitis in neonates with birthweight < 1000 grams: a sequential analysis 
BMC Pediatrics  2012;12:142.
Background
Necrotizing enterocolitis (NEC) is a disease in neonates, often resulting in death or serious medical or neurodevelopmental complications. The rate of NEC is highest in the smallest babies and many efforts have been tried to reduce the rate of NEC. In neonates born below 1500 grams, the rate of NEC has been significantly reduced with the use of various probiotics. This study examines the impact of routine use of a probiotic, Lactobacillus reuteri DSM 17938 (BioGaia®), on the rate of NEC in neonates at highest risk for developing NEC, those with birth weight ≤1000 grams.
Methods
This is a retrospective cohort study comparing the rates of NEC in neonates with birth weight ≤ 1000 grams. The groups are separated into those neonates born from January 2004 to June 30, 2009, before introduction of L. reuteri , and neonates born July 2009 through April 2011 who received routine L. reuteri prophylaxis. The chart review study was approved by our institutional review board and exempted from informed consent.
Neonates were excluded if they died or were transferred within the first week of life. The remainder were categorized as having no NEC, medical NEC, surgical NEC, or NEC associated death. Since no major changes occurred in our NICU practice in recent years, and the introduction of L. reuteri as routine prophylaxis was abrupt, we attributed the post-probiotic changes to the introduction of this new therapy. Rates of NEC were compared using Chi square analysis with Fisher exact t-test.
Results
Medical records for 311 neonates were reviewed, 232 before- and 79 after-introduction of L. reuteri prophylaxis. The incidence of NEC was significantly lower in the neonates who received L. reuteri (2 of 79 neonates [2.5%] versus 35 of 232 untreated neonates [15.1%]). Rates of late-onset gram-negative or fungal infections (22.8 versus 31%) were not statistically different between treated and untreated groups. No adverse events related to use of L reuteri were noted.
Conclusions
Prophylactic initiation of L. reuteri as a probiotic for prevention of necrotizing enterocolitis resulted in a statistically significant benefit, with avoidance of 1 NEC case for every 8 patients given prophylaxis.

2.  Extremely Low Birth Weight Preterm Infants Lack Vasomotor Response in Relationship to Cold Body Temperatures at Birth 
Objective
This study evaluated peripheral vasoconstriction in ELBW infants when body temperature decreased during the first 12-hours of life.
Design
An exploratory, within-subjects design with 10 ELBW infants. Abdominal and foot temperatures were measured every minute. Peripheral vasoconstriction (abdominal > peripheral temperature by 2° C) and abdominal-peripheral temperature difference were also evaluated.
Results
Abdominal and peripheral temperatures were significantly correlated within each infant. One 880 g infant exhibited isolated peripheral vasoconstriction; a 960 g infant had abdominal temperatures more than 1° C higher than peripheral temperatures. Eight smaller infants exhibited no peripheral vasoconstriction and spent most of their observations with peripheral greater than abdominal temperatures. In 8 infants, mean temperature difference was significantly higher when abdominal temperature was less than 36.5° C.
Conclusion
Most ELBW infants did not exhibit peripheral vasoconstriction during their first 12-hours of life, despite low temperatures. ELBW infants’ vasomotor control may be immature during this period.

3.  Low-Dose Aminophylline for the Treatment of Neonatal Non-Oliguric Renal Failure—Case Series and Review of the Literature 
OBJECTIVE
Aminophylline is a methylxanthine with multiple physiologic actions. At low doses, aminophylline can antagonize adenosine and improve renal function via increased glomerular filtration rate. Despite its clinical use, little data exists in neonates for this indication. Therefore, the objective of this report is to describe the impact of aminophylline on renal function indices in a series of neonates with acute renal failure.
MATERIALS AND METHODS
This was a retrospective chart review of 13 neonates with acute renal failure who received aminophylline during a 15-month study period. Aminophylline was administered at 1 mg/kg intravenously or orally every twelve hours. Forty-six percent (n = 6) of the patients received a 5 mg/kg loading dose before initiation of maintenance therapy. Most patients had already received other treatments for renal failure, including diuretics and dopamine.
RESULTS
Resolution of acute renal failure (with normalization of serum creatinine and blood urea nitrogen) was documented in 10 patients (77%). Four of the thirteen patients died from complications due to their prematurity. Failure of low-dose aminophylline was observed in 3 of the 4 patients who died.
CONCLUSIONS
Low-dose aminophylline in neonates with acute renal failure is associated with an improvement in renal function indices.
