Background: We conducted a monthly epidemiological survey to determine the birth prevalence of Robin sequence (RS) and the use of various therapeutic approaches for it., Methods: Between August 2011 and July 2012, every pediatric department in Germany was asked to report new admissions of infants with RS to the Surveillance Unit for Rare Pediatric Diseases in Germany. RS was defined as retro- or micrognathia and at least one of the following: clinically evident upper airway obstruction including recessions, snoring or hypoxemia; glossoptosis; feeding difficulties; failure to thrive; cleft palate or RS-associated syndrome. Hospitals reporting a case were asked to return an anonymized questionnaire and discharge letter., Results: Of 96 cases reported, we received detailed information on 91. Of these, 82 were included; seven were duplicates and two erroneous reports. Given 662,712 live births in Germany in 2011, the birth prevalence was 12.4 per 100,000 live births. Therapeutic approaches applied included prone positioning in 50 infants, followed by functional therapy in 47. Conventional feeding plates were used in 34 infants and the preepiglottic baton plate (PEBP) in 19. Surgical therapy such as mandibular traction was applied in 2 infants, tracheotomy in 3., Conclusion: Compared to other cohort studies on RS, surgical procedures were relatively rarely used as an initial therapy for RS in Germany. This may be due to differences in phenotype or an underrecognition of upper airway obstruction in these infants.

Background: Given the lack of a licensed product (LP), extemporaneous caffeine citrate (ECC) has been used by many hospital pharmacies., Objectives: Since July 2011, an LP has been available in Germany. We prospectively compared the safety profile of ECC and LP in preterm infants with apnea of prematurity., Methods: Between April 2010 and April 2013, selected side effects occurring with ECC or LP were documented in 6 German NICUs for infants ≤34 weeks' gestation using a longitudinal study design. The software developed for daily prescriptions in NICU residents requires entries if any of the following symptoms occurred during the last 24 h: tachycardia (resting heart rate >200/min), clinical or encephalographic seizures, gastric residuals, vomiting, or necrotizing enterocolitis (NEC). ECC and LP were administered at identical doses (20 mg/kg/day loading, 5-10 mg/kg/day maintenance) and in similar formulations either orally or intravenously., Results: 562 infants with 14,590 treatment days on ECC and 538 infants with 12,813 treatment days on LP were evaluated. The mean gestational age was similar (29.20 weeks for ECC vs. 29.14 weeks for LP). No relevant differences were seen concerning tachycardia, gastric residuals, or vomiting, but ECC was associated with a higher risk of NEC (risk ratio: 2.68, 95% CI: 1.01-7.23, p = 0.047) and, albeit not significantly so, seizures (risk ratio: 1.91, 95% CI: 0.53-6.96, p = 0.35)., Conclusion: This survey demonstrates a similar safety profile for both forms of caffeine citrate. The lower NEC and seizure rate seen with the LP is intriguing, but requires confirmation in a controlled study design., (© 2013 S. Karger AG, Basel.)
