Comparative Study
Randomized clinical trials behind level A recommendations in obstetric practice bulletins: compliance with CONSORT statement.
We appraised the compliance of randomized clinical trials (RCTs) cited for level A recommendations in obstetric practice bulletins (OPBs) and published after the CONSORT (Consolidated Standards of Reporting Trials, published 1996) statement. From the CONSORT checklist, we identified 50 separate items the RCTs should describe in the article and assigned 1 point if present; 0, if absent. The CONSORT score was the total points, expressed as a percentage. ⋯ Only four RCTs complied with 90% of the CONSORT statement. RCTs supporting level A recommendations in OPB have variable compliance with CONSORT. Recommendations that lack quality RCTs should prompt further studies into the topic.

We compared the test characteristics of interleukin (IL)-1 beta, IL-6, IL-8, IL-10, IL-12(p-70), tumor necrosis factor-alpha (TNF-alpha), procalcitonin (PCT), C-reactive protein (CRP), and full blood count (FBC) in the diagnosis of neonatal sepsis. This prospective cohort study in the Neonatal Intensive Care Unit of Dunedin hospital of patients between July 1, 2002 and February 28, 2007 included 117 neonates commenced on antibiotics for 164 episodes of suspected sepsis. Blood cultures, FBC, CRP, IL-1 beta, IL-6, IL-8, IL-10, IL-12(p-70), TNF-alpha, and PCT were obtained at the time sepsis was first suspected and for the following 3 days. ⋯ At the time sepsis was first suspected, the most promising individual test was IL-12(p70) with an area under the curve (95% confidence interval [CI]) for the ROC of 0.74 (0.63 to 0.86), which (with a cutoff at 75 pg/mL) had a sensitivity (95% CI) of 28% (20 to 36%) and a specificity of 98% (96 to 100%). IL-10 had a sensitivity of 17% (10 to 23%) and a specificity of 99% (97 to 100%). IL-10 and IL-12(p70) are promising diagnostic tests that can be used to confirm sepsis in neonates.

We hypothesized that prolonged bedside limited-channel amplitude-integrated electroencephalogram (aEEG) monitoring following a standard 1-hour conventional electroencephalogram (cEEG) would increase the detection of subclinical seizures and allow continuous evaluation of the background EEG in neonatal encephalopathy. This may identify complementary roles for these EEG technologies in neonatal units where continuous cEEG monitoring may not be readily available. We prospectively recruited 25 term neonates with a diagnosis of neonatal seizures or encephalopathy. ⋯ Normal background on aEEG and cEEG was associated with normal MRI results, and severe background abnormality (5/24) on both aEEG and cEEG was associated with abnormal MRI results. Data obtained from prolonged aEEG (plus raw EEG) provide similar background activity, enhance seizure detection, and complement standard cEEG in predicting short-term outcomes, based on MRI, in term neonates with seizures or encephalopathy. Limited-channel aEEG technology may provide a pragmatic alternative for longitudinal monitoring of newborn infants with encephalopathy in neonatal units where prolonged video EEG monitoring is not feasible.

Case Reports
Acute chest syndrome during pregnancy as initial presentation of sickle cell disease: a case report.
A 24-year-old woman in her third trimester of pregnancy presented with pulmonary symptoms consistent with acute chest syndrome (ACS). This was her first lifetime manifestation of sickle cell disease. Given the severity of ACS in a patient with no previous symptoms of the disease, we discuss the pathophysiology behind the development of ACS and the importance of practitioner vigilance during sickle cell patients' pregnancies.

Cerebrospinal fluid parameters are of great importance in diagnosing meningitis, but normal values for preterm neonates are based on small, single-center studies. We sought to determine current values for preterm neonate cerebrospinal fluid parameters and assess the association of cerebrospinal fluid parameters with culture proven meningitis. We performed a cohort study of the first lumbar puncture from 4632 neonates < 34 weeks' gestation performed in the years 1997 to 2004 at 150 neonatal intensive care units managed by the Pediatrix Medical Group. ⋯ The area under the receiver operating characteristic curves for white blood cell count, glucose, and protein were 0.80, 0.63, and 0.72, respectively, for prediction of culture-proven meningitis. Cerebrospinal fluid parameters used to diagnose meningitis in the absence of dependable cerebrospinal fluid cultures are unreliable. Caution should be employed when interpreting cerebrospinal fluid parameters in the premature neonate.
