Eating Peanuts While Pregnant May Raise Child's Allergy Risks

Women who eat peanuts during pregnancy may be putting their babies at increased risk for peanut allergy, a new study suggests. U.S. researchers looked at 503 infants, aged 3 months to 15 months, with suspected egg or milk allergies, or with the skin disorder eczema and positive allergy tests to milk or egg. These factors are associated with increased risk of peanut allergy, but none of the infants in the study had been diagnosed with peanut allergy. Blood tests revealed that 140 of the infants had strong sensitivity to peanuts. Mothers' consumption of peanuts during pregnancy was a strong predictor of peanut sensitivity in the infants, the researchers reported in the Nov. 1 issue of the Journal of Allergy and Clinical Immunology.

"Researchers in recent years have been uncertain about the role of peanut consumption during pregnancy on the risk of peanut allergy in infants. While our study does not definitively indicate that pregnant women should not eat peanut products during pregnancy, it highlights the need for further research in order to make recommendations about dietary restrictions," study leader Dr. Scott H. Sicherer, a professor of pediatrics at Jaffe Food Allergy Institute at the Mount Sinai School of Medicine in New York City, said in a journal news release. Sicherer and his colleagues recommended controlled, interventional studies to further explore their findings. "Peanut allergy is serious, usually persistent, potentially fatal, and appears to be increasing in prevalence," Sicherer said.

Cosmetic Surgery Not a Help for Body Dysmorphic Disorder

One in five people with a condition known as body dysmorphic disorder (BDD) undergo cosmetic procedures, but only 2 percent of them experience a reduction in the severity of their condition after their treatment, researchers say. "BDD is a psychiatric disorder characterized by preoccupation with an imagined or slight defect in appearance, which causes clinically significant distress or functional impairment. A majority of these individuals believe they have an actual deformity that can be corrected by `cosmetic treatments to fix these perceived defects rather than seeking psychiatric interventions," study co-author Dr. Katharine A. Phillips, director of the body image program at Rhode Island Hospital, said in a hospital news release.

Phillips and her colleagues looked at 200 people with BDD and found that 31 percent sought and 21 percent underwent surgical or minimally invasive cosmetic treatment. Among those who actually had a cosmetic procedure, most continued to have BDD symptoms afterwards, and in some cases they developed new preoccupations with their appearance, the researchers noted. The investigators also surveyed 265 cosmetic surgeonsand found that 178 (65 percent) reported treating patients with BDD. But among those cases, only 1 percent of the treatments resulted in symptom improvement for patients with BDD, the study authors reported.

"These findings, coupled with reports of lawsuits and occasionally violence perpetrated by persons with BDD towards physicians, have led some to believe that BDD is a contraindication for cosmetic treatment," Phillips said. The most common surgical procedures sought by BDD patients are rhinoplasty (nose jobs) and breast enlargements, while the most common minimally invasive treatments are collagen injections and skin treatments known as microdermabrasion, the study authors noted. The researchers also found that three-quarters of procedures requested by BDD patients involved facial features and that more than one-third of patients received multiple procedures.
