Background: We investigated whether multiple food allergies could be safely prevented by simultaneously administering very small amounts of multiple foods. Methods: Infants 3–4 months old with atopic dermatitis from 14 primary care pediatric clinics in Japan were enrolled in this randomized, placebo-controlled trial. The infants were administered either mixed allergenic food powder (MP) containing egg, milk, wheat, soybean, buckwheat, and peanuts, or placebo powder (PP). The amount of powder was increased in a stepwise manner on weeks 2 and 4, and continued until week 12. The occurrence of food allergy episodes after powder intervention was assessed at 18 months old. This trial was registered with the University Hospital Medical Information Network Clinical Trials Registry (number UMIN000027837). Results: A total of 163 participants were randomly allocated to either the MP group (n = 83) or the PP group (n = 80). The incidence of food allergy episodes by 18 months was significantly different between the MP and PP groups (7/83 vs. 19/80, respectively; risk ratio 0.301 [95% CI 0.116–0.784]; P = 0.0066). Egg allergies were reduced in the MP group. In addition, food allergy episodes from any of the other five foods were significantly reduced, although the reductions in those due to individual foods were not significant. Conclusions: Gradually increasing the intake of very small amounts of multiple foods in early infancy can safely reduce the incidence of egg allergies. Other foods may also suppress food allergies, but no definitive conclusions could be reached.

Neonatal or infantile uterine prolapse is a quite rare condition and is usually managed with conservative treatment. There is no standard surgical treatment for infantile uterine prolapse, and to the best of our knowledge, only 2 out of 30 patients suffering from it have been reported to undergo surgical repair in English literature since 1961. We here report the first successful case of laparoscopic repair for uterine prolapse in an infant. The patient was a 2-month old girl who had sacral myelomeningocele and Chiari type 2 malformation. She had undergone closure of myelomeningocele and ventriculoperitoneal shunting within 6 weeks after birth. At 7 weeks of age, the rectum and the uterus prolapsed, and the prolapse gradually deteriorated. Conservative treatments including repeated digital reduction, use of ointment and glycerin enema, and placement of a Foley catheter into the vagina were not effective. At the age of 100 days, she underwent laparoscopic hysteropexy and rectopexy. Three ports were placed on the umbilicus and the bilateral abdomen, and the bilateral mesovaria were sutured to the anterior abdominal wall to improve the visualization of the pelvis. The rectum and the uterine body were directly sutured to the sacral promontory with 2 non-absorbable braided sutures each, not using mesh prosthesis. The postoperative course was uneventful and neither uterine nor rectal prolapse has recurred for 2.5 years. We plan to follow up the patient for a long period since the long-term prognosis is not known.
