Immigrant and Native-born Mexican-American parents' involvement in a public school: a preliminary study

Mexican-American parents of Texas elementary school students were surveyed to compare the types of school involvement in which immigrant and U.S.-born parents engage. Those completing the questionnaire included 246 mothers and 39 fathers born in Mexico as well as 95 mothers and 13 fathers born in the United States. More immigrant parents than U.S.-born parents indicated they helped their children with school work, attended school board meetings, volunteered at school, participated in parent-teacher conferences, went to school functions, served as room mother, engaged in school fundraising, and were present during parent advisory committee meetings.

Smokeless tobacco use by secondary students in a Mexican bordertown

Of secondary students living in a Mexican bordertown, 67 boys and 45 girls aged 13 to 18 years, 5 boys reported trying chewing tobacco, but none reported current use, and 61 students believed such use could cause cancer. Low prevalence may be related to low exposure to advertising.

[Sertoli-Leydig-cell ovarian tumor with a retiform pattern and heterologous elements: a rare cause of virilization]

The case is presented of a young female with virilization signs and total circulating testosterone levels above 4 ng/ml, without a concomitant increase in cortisol, 17 OH-progesterone, DHEA-S, or androstenedion levels. On CT scan exam a tumoral mass in the left ovary was observed with polycystic characteristics similar to those observed in ovarian cystadenoma, inspite of the fact that most androgenic ovarian tumors are solid. The pathological study revealed an ovarian Sertoli-Leydig tumor associated to a reticular pattern with heterologous chondroid and mucinoid elements of cystadenoma.
