Diagnosis and Treatment of Ewing Sarcoma

Ewing's sarcoma is a Malignant small round cell neoplasm that mostly affects the young age on the body axis and long bones. The incidence is quite rare yet it is notorious for its poor prognosis. Certain characteristics of the patient could determine the prognosis. Diagnosis is often made late due to the deep situated mass or the axial situated mass. Imaging beginning from plain radiograph to CT and MRI is necessary to support the diagnosis and determine the stage of the disease. Diagnosis establishment still requires histopathological examination now supported with spesific immnuohistochemistry staining. Histopathological results could also be used to evaluate prognosis in the form of response towards chemotherapy. Management of Ewing's sarcoma requires systemic chemotherapy combined with surgery or radiotherapy for local control. Chemotherapy protocols for Ewing's sarcoma is continuously developed for intensification using supportive modality treatment advancements. Local control on Ewing's sarcoma is performed by combining surgery and radiotherapy. The defect after surgery can now be reconstructed to increase the quality of life

Thin shell wormhole due to dyadosphere of a charged black hole

To explain Gamma Ray Bursts, Ruffini argued that the event horizon of a charged black hole is surrounded by a special region called, the Dyadosphere where electric field exceeds the critical value for $e^+$ $e^-$ pair production. In the present work, we construct a thin shell wormhole by performing a thought surgery between two dadospheres. Several physical properties of this thin shell wormhole have been analyzed.Comment: 10 pages, 2 figures. Accepted in Mod.Phys.Lett.
