RESUMO
Osteosarcomas are highly malignant bone tumours. Its appearance in craniofacial bones is a rare entity and accounts for only 1% of all head and neck malignancies. We present an uncommon case report of a 42 year old male patient with osteosarcoma of left maxilla, which was successfully excised under general anesthesia. The patient reported to us with a history of pain, swelling, pus discharge and tooth extraction, which led to the differential diagnosis of suppurative osteomyelitis, dentoalveolar abscess, benign odontogenic tumour, an infected cyst etc. Histopathological examination of incisional biopsy was reported as chondromyxoid fibroma which is a rare benign tumour. However the excisional biopsy specimen was reported as osteosarcoma of maxilla. The clinical presentation, diagnostic challenges and its therapeutic approach are addressed. This case serves to emphasize the need to recognize osteosarcoma when it presents in unexpected locations, especially because of its rarity.

Breast-feeding provides protection against infections and contains numerous factors that modulate and promote the development of the infant immune system. These factors include secretory IgA, antimicrobial proteins like CD14, cytokines, and fatty acids. Studies examining the role of breast-feeding in the development of allergic disease in infants demonstrate potentially protective as well as neutral or nonprotective effects, likely due to the heterogeneity in their study design. In this overview, we explore the potential role of immune factors in the breast milk, as well as selected probiotics, in the development of allergy.

To identify potential molecular determinants of tumor biology and possible clinical outcomes, global gene-expression patterns were analyzed in the primary tumors of patients with metastatic renal cell cancer by using cDNA microarrays. We used grossly dissected tumor masses that included tumor, blood vessels, connective tissue, and infiltrating immune cells to obtain a gene-expression "profile" from each primary tumor. Two patterns of gene expression were found within this uniformly staged patient population, which correlated with a significant difference in overall survival between the two patient groups. Subsets of genes most significantly associated with survival were defined, and vascular cell adhesion molecule-1 (VCAM-1) was the gene most predictive for survival. Therefore, despite the complex biological nature of metastatic cancer, basic clinical behavior as defined by survival may be determined by the gene-expression patterns expressed within the compilation of primary gross tumor cells. We conclude that survival in patients with metastatic renal cell cancer can be correlated with the expression of various genes based solely on the expression profile in the primary kidney tumor.
