Anaphylaxis to PEGylated liposomal echocardiogram contrast in a patient with IgE-mediated macrogol allergy.
The authors describe a case of anaphylaxis to PEG 5000-conjugated liposomal perflutren, a perfluorocarbon gas used as echocardiography contrast. They conclude that, given the severity of the patient’s reactions, allergists, cardiologists, and radiologists should become aware of the possibility of hypersensitivity reactions to macrogols to facilitate prompt diagnosis, treatment, and future avoidance. They suggested that use of PEGylated liposomal perflutren and other drugs and devices containing HMW PEG be avoided in favor of alternatives when patients report previous immediate hypersensitivity reactions consistent with severe macrogol allergy. They recommended further studies.

Prenatal diagnosis of a ventral abdominal wall defect.
This paper is a case study describing an infant diagnosed prenatally with fetal ultrasonography with multiple abnormalities including a ventral abdominal wall defect and confirmed herniation of the liver with the portal vein extending outside the abdomen, stomach, small bowel, and majority of the large bowel without an overlying membrane. The kidneys were enlarged as well. Multiple surgeries were performed. Ultimately the infant died 38 days after birth.
