A Case of Lactation Anaphylaxis.

We describe the case of a patient who presented multiple times to the emergency department (ED) with recurrent episodes of anaphylaxis in the immediate postpartum period. It was initially thought to be idiopathic in nature on previous visits, but was ultimately diagnosed as lactation anaphylaxis and successfully managed. The diagnosis was suspected when the detailed history revealed recurrent allergic symptoms with each episode of breastfeeding.

Concurrent Visual Feedback, Practice Organization, and Spatial Aiming Accuracy in Rapid Movement Sequences.

While the availability of visual feedback is a well-known factor influencing the accuracy of rapid aiming movements, little is known about how vision might interact with a contextual variable like practice organization. In the current study, the interaction of concurrent visual feedback (CVF) and practice organization on aiming movement accuracy was investigated in the dominant limb of 40 college-aged participants. Participants performed "triplets" of rapid aiming movements with a lightweight lever in the sagittal plane involving short (20°), medium (40°), long (60°) distances and were randomly assigned to one of four groups (n=10) in a 2 (Group: Blocked Practice, Random Practice) × 2 (Vision: CVF, no CVF) factorial design.
