TL;DR: Four cases of air block syndrome were observed as an early and unusual presentation of vascular ring in infants, and two case reports are included to demonstrate air block in relation to vascular rings in neonates.
Abstract: Seventeen cases of vascular ring have been encountered at Ochsner Clinic over the past 22 years. Anatomic configurations consisted of double aortic arch in 11 cases, right aortic arch with left ligamentum arteriosum in five cases, and aberrant right subclavian artery in one case. In four cases chest x-ray films revealed air block or hyperinflation and led to further diagnostic tests. The definitive diagnostic methods included esophagogram in 15 cases, aortography in 14 cases, two-dimensional echocardiography in one case, and esophagoscopy/bronchoscopy in eight cases. Presenting symptoms were respiratory in 13 cases and feeding difficulties in three; one asymptomatic case was found incidentally. Four cases of air block syndrome were observed as an early and unusual presentation of vascular ring in infants. Hyperinflation of the lung fields on chest x-ray film should spur suspicion of a possible vascular ring. Two case reports are included to demonstrate air block in relation to vascular rings in neonates.

TL;DR: The difference in survival demonstrates the efficacy of ECMO for the treatment of severe MAS, and it is believed that when established criteria are met, ECMO should be instituted without delay.
Abstract: Meconium aspiration syndrome (MAS) is a common cause of morbidity and mortality in neonates Chemical pneumonitis can lead to persistent pulmonary hypertension of the newborn (PPHN) with irreversible hypoxia and death Extracorporeal membrane oxygenation (ECMO) for the treatment of severe PPHN became available at the Ochsner Foundation Hospital in September 1983 We reviewed the first 28 cases in which ECMO was used for the treatment of PPHN due to severe MAS; 26 of the 28 infants survived During the three years preceding our development of ECMO capability, ten neonates had PPHN due to severe MAS and met the criteria for ECMO; only three survived The difference in survival demonstrates the efficacy of ECMO for the treatment of severe MAS We believe that when established criteria are met, ECMO should be instituted without delay

TL;DR: The 1987 Comprehensive Blood Bank Survey consisted of four shipments of samples that presented graded challenges in ABO and D typing, crossmatching, and antibody detection and identification and un graded challenges for antigen typing and ungraded serum samples for educational purposes.
Abstract: The 1987 Comprehensive Blood Bank Survey consisted of four shipments of samples Each presented graded challenges in ABO and D typing, crossmatching, and antibody detection and identification and ungraded challenges for antigen typing and ungraded serum samples for educational purposes Practice patterns were elicited through supplemental questions, generally about issues raised by the survey samples Two of the surveys showed significant problems Set J-C included serum with anti-Lea, which was not detected by some participants Anti-Dia was one of two antibodies in the J-D graded sample, and this additional antibody was not detected by a significant number of participants Although minor problems were encountered in other challenges, in general performance was good
