Diagnosis and treatment of Ewing's Sarcoma of the tongue
2019
The Ewing's sarcoma Family of Tumors (EFT) includes classic Ewing's Sarcoma (ES) of bone, Extraskeletal Ewing's Sarcoma (EES) and malignant peripheral primitive Neuroectodermal Tumor (pNET) of bone and soft tissue. ES is an aggressive tumor with a high incidence of local recurrence and distant metastasis. The skeletal form is more common and typically occurs in the long bones of the extremities. The extra skeletal form occurs in the soft tissues of the lower extremities, paravertebral tissues, chest wall, retroperitoneum and rarely in the head and neck region in about 1- 4% of cases. Involvement of the head and neck is usually identified in the nasal or oral cavities, sinuses or soft tissue…

ROLE of SURGERY for NONMETASTATIC ABDOMINAL RRHABDOMYOSARCOMAS. A Report from the Italian and German Cooperative Groups Studies.
2003
In the current study, the Authors aim to evaluate clinical features and treatment results observed in patients from the German and Italian studies who had nonmetastatic abdominal rhabdomyosarcomas.
Initial surgery for localized rhabdomyosarcoma: a report from the italian Soft Tissue Sarcoma Cooperative Group Studies.
2005
Objective. Analysis of the initial surgical approach in patients with localized rhabdomyosarcoma, enrolled in Italian Studies (1979-2003). Methods. Surgical records of 587 patients were evaluated. As primary surgery, the excision was recommended if microscopically complete, otherwise biopsy was preferable. Results. The initial biopsy, performed in almost 50% of patients in RMS-79 protocol, has been adopted more often in the protocol RMS-88 and 96. However, the “complete resection” rate has remained quite stable through the years, as well as the percentage of microscopic residue. The macroscopic residue disease has been more important in RMS-88 study than in RMS-96. Most GUnBP tumors and abo…
Antibodies to human herpes virus type 8 (HHV8) in general population and in individuals at risk for sexually transmitted diseases in Western Sicily.
2000
Human herpes virus 8 (HHV8) appears to be the primary aetiologic agent of Kaposi sarcoma (KS). To study the distribution of HHV8, a seroepidemiological study was carried out in western Sicily, where a high incidence rate of classical KS is well documented.A total of 970 sera of healthy human immunodeficiency virus (HIV) negative individuals of general population (1-70 years old) and 742 sera of individuals in different risk groups for HIV infection were evaluated by means of an indirect immunofluorescence assay able to detect antibodies to lytic and latent HHV8 antigens.Crude seroprevalence to HHV8 antigens was 11.5% in the general population, and it increased significantly with age from 6%…
Silyl modification of biologically active compounds. 13. Synthesis, cytotoxicity and antibacterial action ofN-methyl-N-(2-triorganylsiloxyethyl)-1,2,…
2012
A series of N-methyl-N-(2-triorganylsiloxyethyl)-1,2,3,4-tetrahydro(iso)quinolinium iodides has been synthesized via dehydrocondensation reaction of N-(2-hydroxyethyl)-1,2,3,4-tetrahydroisoquinoline, N-(2-hydroxyethyl)-1,2,3,4-tetrahydroquinoline and 4,4-dimethyl-N-(2-hydroxyethyl)-4-sila-1,2,3,4-tetrahydroisoquinoline with trialkyl(aryl)hydrosilanes and subsequent alkylation, and characterized by 1H, 13C and 29Si NMR and mass spectroscopy. The biological activity data exhibited a marked enhancement of inhibitory activity against tumour cell lines and almost all the test bacterial/fungal strains in comparison with their 2-hydroxyethyl precursors. Cytotoxicity in the microgram range against …
Matrix metalloproteinases 2 and 9, and extracellular matrix in Kaposi's sarcoma
2010
Matrix metalloproteinases (MMPs) are associated with Kaposi's sarcoma (KS) tumorigenesis and may contribute to the mechanism of KS invasive growth. To date, only a few MMPs have been studied in KS lesions, and exactly which MMPs are involved in KS development and progression remains unanswered. However, MMPs 2 and 9 have been associated with different phases of angiogenesis, but their role in the proteolytic modification of the extracellular matrix has not been investigated. The results of this study confirm that MMPs, specifically MMP-2 and MMP-9, can contribute to angiogenesis by disrupting the vessel basement membrane and other extracellular matrix barriers, and enabling endothelial cell…
