RESUMO
Necrophagous insects, mainly Diptera and Coleoptera, are attracted to specific stages of carcass decomposition, in a process of faunistic succession. They are very important in estimating the postmortem interval, the time interval between the death and the discovery of the body. In studies done with pig carcasses exposed to natural conditions in an urban forest (Santa Genebra Reservation), located in Campinas, State of São Paulo, southeastern Brazil, 4 out of 36 families of insects collected - Calliphoridae, Sarcophagidae, Muscidae (Diptera) and Dermestidae (Coleoptera) - were considered of forensic importance, because several species were collected in large numbers both visiting and breeding in pig carcasses. Several species were also observed and collected on human corpses at the Institute of Legal Medicine. The species belonged to 17 different families, 6 being of forensic importance because they were reared from human corpses or pig carcasses: Calliphoridae, Sarcophagidae, Muscidae, Piophilidae (Diptera), Dermestidae, Silphidae and Cleridae (Coleoptera). The most important species were: Diptera - Chrysomya albiceps, Chrysomya putoria, Hemilucilia segmentaria, Hemilucilia semidiaphana (Calliphoridae), Pattonella intermutans (Sarcophagidae), Ophyra chalcogaster (Muscidae), Piophila casei (Piophilidae); Coleoptera - Dermestes maculatus (Dermestidae), Oxyletrum disciolle (Silphidae) and Necrobia rufipes (Cleridae).

A cross-sectional study was carried out to estimate prevalence of child abuse with battering among patients under age 14 for alleged disciplinary purposes. The reference population were children attending pediatric out-patient services at the University Hospital in Campinas, State of São Paulo, Brazil, a city of one million inhabitants with universal coverage in terms of accessing health care in the unit under study. Interviews were carried out with 130 parents or guardians in a randomly selected group according to order of attendance, and the prevalence of child abuse was estimated at 10.8%, considering as positive cases those where parents referred child battering under age one year or where there was evidence of bodily lesion over age one year. A validation study for the experimental questionnaire is proposed in order to allow for future estimation of population prevalence or incidence. The use of qualitative methods is also recommended as a means of gathering detailed data on socio-psychological determination for the supposedly disciplinary aggression with child abuse.
RESUMO
Os autores apresentam um caso de schwanoma maligno solitario do mediastino posterior, com sintomas evidentes de compressao radicular. Comentam sua sinonimia, histogenese e propagacao. Ainda que haja ausencia de linfonodos loco regionais, a presenca de pequeno tumor no hemitorax esquerdo, metastases osseas e sinais de hipertensao intra craniana, sugerem uma possivel disseminacao hematogenica do tumor
