Twenty-five mothers of all social class levels were asked to tell, as if to a 6-year-old child, the stories suggested by several cartoon picture sequences. These stories, tape-recorded, were played to a hundred 6-year-old white male children of high and low social class levels, who were then asked standard comprehension questions about their content. Analysis of the comprehension scores revealed significant main effects of social class of adult speaker and of social class of child listener but no interaction of these two variables. Further analysis of transcriptions of the stories revealed two characteristics, namely the factual information included in the stories and the use of nonstandard grammar, which seemed to mediate the effects of both social class and speaker IQ on comprehension.
Four cases of clear cell adenocarcinoma of the genital tract in young women are presented. All patients were treated with radiation therapy. Two of the patients subsequently developed chest metastases. Three patients have died of the disease, and the other is without evidence of disease. Two patients were treated with chemotherapy, and a positive response to the chemotherapy was observed. Because this is an aggressive disease, one should consider the use of chemotherapeutic agents as a part of the primary therapy.
