Effects of rejuvenation and frozen storage on 42-day-old AS-3 RBCs.

Background: A storage period of 42 days has been approved by the FDA for RBCs stored in NUTRICEL (AS-3). This study was undertaken to provide data to the FDA about the feasibility of salvaging AS-3 RBCs at the end of their storage period by rejuvenation and freezing, and to evaluate the effect of rejuvenation on indicators of RBC function.

Study Design And Methods: Healthy adults (n = 22) donated 450 mL of whole blood, and RBC components were prepared at two study sites.

Effect of rejuvenation and frozen storage on 42-day-old AS-1 RBCs.

Background: The FDA has approved a 42-day storage period for RBCs stored in ADSOL (AS-1). This study was undertaken to provide data for the FDA about the feasibility of salvaging AS-1 RBCs at the end of their storage period by rejuvenation and freezing.

Study Design And Method: The investigation, consisting of a study (n = 10) and control (n = 6) arm, was carried out in two centers.

An irreducible knee dislocation: a case report.

An 8-year-old man presented after sustaining an injury during a fall. A closed reduction attempt failed, and after several tests, an open reduction was performed. With posterolateral dislocation of the knee, there can be anterior cruciate ligament, posterior cruciate ligament, and medial collateral ligament disruption.

Ultrasonography in the management of developmental dysplasia of the hip (DDH).

Real time ultrasonography, according to the method of Graf, was performed on 113 infant hips because of abnormal physical findings (ranging from hip clicks to frank dislocation). Three parameters were measured on the standard coronal images: alpha and beta angles of Graf and the d/D ratio of Morin. Results indicated that the presence of hip clicks (88 hips) in general is a benign condition and not associated with abnormal anatomy.
