[EX Q]: Question: Are levels of soluble CD30 in cord blood and peripheral blood during childhood correlated with the development of atopic disease or a family history of atopy?
Answer: These findings indicate that the sCD30 concentration in cord blood is not a reliable prognostic indicator of, nor a useful diagnostic marker for, atopic disease in children up to 7 years of age. If such correlations do exist, they might be masked by age-dependent variations in the circulating levels of sCD30, which may reflect individual differences in the maturation of children's immunological responses.

[EX Q]: Question: Do `` Pleats fold '' technique of amniotic membrane transplantation for management of corneal perforations?
Answer: The AM transplantation procedure may be an effective option for treating corneal perforations when the wound is circular or irregular, except for incised wounds. Our "Pleats Fold" AM transplantation technique can achieve definite closure and effectively repair wounds of various sizes. Postoperative astigmatic values were acceptable. Therefore, we recommend this procedure for repairing lesions <3 mm in diameter that do not involve the central cornea and that are infection free.
