Leiomyosarcoma of the colon: report of a case and analysis of the relationship of histology to prognosis.

A case of primary leiomyosarcoma of the colon in a patient without gastrointestinal symptomatology who initially manifested a metastasis in the parotid region is described. Review of the literature indicates that mitotic activity is the most reliable histologic criterion for prognosis. Three of five patients with tumors manifesting high mitotic activity succumbed to widespread metastatic disease within four months of initial diagnosis. The prognosis is generally favorable for those patients whose neoplasms have low or moderate mitotic rates.

A composite malignant tumour of the elderly female breast.

A composite malignant tumour arising in the breast of an elderly woman is described. The cystic tumour containing areas of squamous metaplasia, bone formation, adenocarcinoma, and osteosarcoma was surrounded by the typical changes of mammary dysplasia (fibroadenosis). The classification and acceptance of such tumours is highly debatable. There is no one acceptable classification of breast sarcomas and hence the prognosis of such neoplasms, particularly those containing heterologous tissues, is poorly defined. Evidence is presented in support of such composite tumours as being definite entities which arise from the closely associated epithelial and mesenchymal components of the breast simultaneously.

Group protocol to mitigate disaster stress and enhance social support in adolescents exposed to Hurricane Hugo.

Literature reports that cognitive understanding and social support can mitigate stress in both adults and adolescents. As a subcomponent of the Carolina Adolescent Health Project (CAHP), this research evaluated the efficacy of a Cognitive Social Support (CSS) group protocol designed to mitigate the disaster stress of adolescents who had been exposed seriously to Hurricane Hugo. A purposive sample of 259 students participated in and evaluated the CSS. This article reports the specific structure, content, process, rationale, and cost of the CSS. Evaluations indicated that 82% of the students evaluated the small-group component of the CSS as "very good" or "excellent," while 70% rated the large-group component as "very good" or "excellent."
