摘要：THE WORLDWIDE TREND FOR MEDICAL PRACTICE, IN GENERAL, AND FOR HISTOPATHOLOGICALLESIONS DIAGNOSIS, IN PARTICULAR, TURNS IN FAVOR FOR PROTOCOL USE, AS IN MANYCOUNTRIES AND SPECIALTIES, THESE ARE NOT WELL IMPLEMENTED. OUR AIM REFERS TO ANEXPERIMENT THAT INVOLVED FIVE AVERAGE EXPERIENCED OBSERVERS THAT EXAMINED 10PLACENTAS WITH CHORIOAMNIONITIS, 4 ACUTE CASES AND 6 CHRONIC CASES. THEY HAD TOISSUE THE DEGREE OF EXTENT OF BASIC LESIONS: HYALINE DEPOSITION, INFLAMMATION,FIBROSIS, NECROSIS AND HYPEREMIA. THE INSTRUMENT USED WAS A LIKERT SCALE WITH FIVEDEGREES OF INTENSITY. KAPPA STATISTICAL CALCULATIONS PROVED A SLIGHT DIFFERENCEBETWEEN THE FIVE EXAMINATORS IN REGARDING THE APPRECIATION OF LESION SEVERITY. THEINTEROBSERVER AGREMEENT WAS BETWEEN 0.04 TO 0.14 WITH HIGHER CONSISTENCY TOWARDOBVIOUS LESIONS WITH ALPHA VALUES FROM 0.61 TO 0.81.THUS SHOWING THE NECESSITY FOR AFAR PRECISE DIAGNOSIS PROTOCOL TO BE IMPLEMENTED, AS THE LESIONS INCHORIOAMNIONITIS PLACENTA MA BE VERY DIFFICULT TO APRECIATE.
