Cytogenetic description of breast fibroadenomas: alterations related solely to proliferation?
(2001-08) BURBANO, Rommel Mario Rodriguéz; LIMA, Eleonidas Moura; KHAYAT, André Salim; BARBIERI Neto, J.; CABRAL, Isabel Rosa; BASTOS JR., L.; BAHIA, Marcelo de Oliveira; CASARTELLI, Cacilda
Twelve breast fibroadenomas were analyzed cytogenetically and only four were found to have clonal alterations. The presence of chromosomal alterations in fibroadenomas must be the consequence of the proliferating process and must not be related to the etiology of this type of lesion. In contrast, the few fibroadenomas that exhibit chromosomal alterations are likely to be those presenting a risk of neoplastic transformation. Clonal numerical alterations involved chromosomes 8, 18, 19, and 21. Of the chromosomal alterations found in the present study, only monosomy of chromosomes 19 and 21 has been reported in breast fibroadenomas. The loss of chromosome 21 was the most frequent alteration found in our sample. The study of benign proliferations and their comparison with chromosome alterations in their malignant counterparts ought to result in a better understanding of the genes acting on cell proliferation alone, and of the genes that cause these cells to exhibit varied behaviors such as recurrences, spontaneous regression and fast growth.

Violence is a serious public health problem and notification of incidents is fundamental for epidemic surveillance and for the definition of priorities and public politics of health prevention and promotion. The study sought to characterize the occurrence of domestic violence, sexual and other forms of violence, based on the information of the database of the Information System of Notification of Offences (Sinan), on the records of violence of the city of Belém in the state of Pará, in the period from January 2009 to December 2011. In this period 3,267 notifications were recorded, which represented an increase of 240% in the number of notifications of the year 2009 compared to 2011. In relation to the sex of the victims it was observed that, on average, 83.2% of cases against women and this proportion was similar in all three years analyzed. Sexual violence was the most prevalent with 41.8% of reported cases; followed by psychological violence at 26.3% and physical violence at 24%. The results show that notification is fundamental for understanding the profile of violence and for intervention and elaboration of integrated public politics that promote health and the quality of life in this area of Brazil.
