Rates of New Peanut Allergy and Discontinuation Following Introduction in High-Risk Infants.

Background: Peanut introduction guidelines recommend that infants with severe eczema and/or egg allergy consume 6 g of peanut protein weekly to prevent peanut allergy. Rates of new peanut allergy after introduction and adherence remain under study.

Objective: To determine compliance with peanut introduction guidelines, rates of new peanut allergy, and reasons for discontinuation of peanut consumption in a cohort of high-risk infants.

56-year-old male with HIV and sudden cardiac arrest.

A 56-year-old man with well-controlled human immunodeficiency virus, anxiety, depression, and hypercholesterolemia developed acute urticaria, lip angioedema, and respiratory distress after consumption of a cheeseburger, French fries, lemonade, and ibuprofen. He was evaluated in the emergency department and, during admission, developed asystole, diaphoresis, pallor, and a brief episode of posturing that was treated with two doses of epinephrine. Results of the initial workup with electrocardiogram, troponin, complete blood cell count, and comprehensive metabolic panel were normal.

Development of object control in the first year: emerging category discrimination and generalization in infants' adaptive selection of action.

This research examined the development of adaptive generalization in infants' object-directed actions. Infants ages 9 and 12 months participated in an object manipulation task with stimulus objects from 2 categories that differed in shape and weight and that bore a consistent shape or weight correspondence. Weight differences between categories affected infants' actions required to handle objects effectively.
