ABSTRACT
In the present contribution we compared the entomological succession pattern of a burned carcass with that of an unburned one. For that, we used domestic pig carcasses and focused on Calliphoridae, Muscidae and Sarcophagidae flies, because they are the ones most commonly used in Postmortem Interval estimates. Adult and immature flies were collected daily. A total of 27 species and 2,498 specimens were collected, 1,295 specimens of 26 species from the partially burned carcass and 1,203 specimens of 22 species from the control carcass (unburned). The species composition in the two samples differed, and the results of the similarity measures were 0.875 by Sorensen and 0.756 by Bray-Curtis index. The results obtained for both carcasses also differ with respect to the decomposition process, indicating that the post mortem interval would be underestimated if the entomological succession pattern observed for a carcass under normal conditions was applied to a carbonized carcass.

Eleven new cases of colorectal carcinoma in children (0-15 years of age) are added to the 212 cases already described in the literature. Mucinous adenocarcinoma was the most frequent histological type. Acute abdominal obstruction was the most frequent presentation. A radiologic diagnosis of malignancy was made in only six of eleven cases. The interval between onset of clinical symptoms and diagnosis ranged from two days to one year. Duration of symptoms, pathologic findings, stage, and prognosis differed markedly as compared with adult colorectal carcinomas. In spite of its rarity, colorectal malignancies may occur in children.

Four children developed lipoid pneumonia following ingestion of mineral oil for the treatment of partial small bowel obstruction by Ascaris lumbricoides whorl. CT of the chest showed negative Hounsfield numbers which may prove useful in diagnosis.

Quatro casos de pneumonias lipoides em criancas que aspiraram oleo mineral sao apresentados. Em tres houve iatrogenia. Em todos o diagnostico foi estabelecido associando uma historia de ingestao de oleo com radiografias, mostrando infiltrados difusos que nao involuiram com a terapeutica. Houve confirmacao anatomopatologica em tres casos

Sao discutidos sete casos de tumor renal na infancia com compromentimento osseo importante, tendo sido os seis primeiros casos ja submetidos a publicacao previa. Essas neoplasias haviam sido anteriormente classificadas como tumores de Wilms de caracteristicas atipicas. A revisao histologica, feita a luz dos novos conceitos, reclassificou-as como: tumor renal da infancia metastatizante para osso - TRIMO (tres casos), rabdomiossarcoma (um caso), sarcoma indiferenciado (dois casos) e neoplasia maligna indiferenciada (um caso)

Six cases of childhood renal tumor with extensive bone involvement are reported. The neoplasms had been classified originally as Wilms tumor with atypical clinical and pathologic features. Subsequent to a retrospective histologic analysis, the lesions were reclassified as follows: three cases as bone-metastasizing renal tumors of childhood, one case as rhabdomyosarcoma, one case as undifferentiated sarcoma, and one case as undifferentiated malignant neoplasm.
