METHOD FOR PREDICTION OF THYMOMEGALIA IN THREE-MONTH-OLD MATURE NEWBORNS SUFFEREDPRENATAL INFLUENZA B COMPLICATED BY PLACENTITIS Russian patent published in 2015 - IPC G01N33/483 

Abstract RU 2555523 C1

FIELD: medicine.

SUBSTANCE: after thymomegalia has been excluded, tissue specimens of three-day-old mature newborns are studied to evaluate areas of inflammation changes in points in the placental umbilical cord (A), in the foetal placenta (B), in the maternal placenta (C), in extraplacental membranes (D); then thymomegalia is predicted by a discriminant equation: DE=-0.350×A-1.176×B-1.690×C-1.203×D, wherein DE is a discriminator function with a threshold equal to - 15.00. If DE is equal to or more than the threshold, the absence of thymomegalia is predicted; if D is less than the threshold, thymomegalia is predicted, whereas the score is taken at: (A) - 1 point - no inflammation, 2 points - amnionitis, 3 points - leukocytic infiltration in the Wharton's jelly, 4 points - phlebitis, 5 points - arteriitis, 6 points - a combination of two or more areas of inflammation: in blood vessels or in vessels and in the Wharton's jelly, (B) - 1 point - no inflammation, 2 points - chorioamnionitis, 3 points - villusitis, 4 points - vasculitis, 5 points - intervillesitis, 6 points - a combination of two or more areas of inflammation, (C) - 1 point - no inflammation, 2 points - villusitis, 3 points - vasculitis, 4 points - intervillesitis, 5 points - deciduitis, 6 points - a combination of two or more areas of inflammation, (D) - 1 point - no inflammation, 2 points - amnionitis, 3 points - chorioamnionitis, 4 points - deciduitis, 5 points - choriodeciduitis, 6 points - a combination of two or more areas of inflammation.

EFFECT: enabling the prediction of thymomegalia in the three-month-old mature newborns suffered prenatal influenza B complicated by placentitis.
