Filter by:The main aim of the study is to investigate the proven effect of dexamethsone on the duration of the interscalene block. The investigators try to define optimal dose and volume for ropivacaine, when used together with dexamethsone. The current literature uses often very high volumes of ropivacain when used together with dexamethasone. The investigators try to research the effect of using dexamethsone together with low volume, high concentration ropivacaine for interscalene blockade. The investigators' hypothesis is that dexamethasone has an positive effect on the pain free after used together with ropivacaine at the scalene block.
Post thoracotomy pain syndrome still affects 50% of patients after a thoracic surgery. Pathogenesis is unclear but there is growing evidence that neuro inflammation may play a significant role. Dexamethasone is a very potent anti-inflammatory drug. The hypothesis of this study is that dexamethasone, given pre operatively, would help reduce the incidence of post thoracotomy pain syndrome 3 months after surgery, by reducing the inflammatory response, in patients undergoing elective thoracic surgery that includes thoracic epidural analgesia.
RATIONALE: Bortezomib may stop the growth of myeloma cells by blocking proteasome activity. Cyclophosphamide and dexamethasone may work in different ways to stop the growth of myeloma cells by stopping them from dividing or by killing the cells. Granulocyte Clone Stimulating Factor (G-CSF) possesses the ability to mobilize the plasma cells to detach from myeloma niche, so as to promote drug sensitivity. PURPOSE: This phase Ⅱ trial is to study how well combination of G-CSF, bortezomib, cyclophosphamide and dexamethasone works in treating patients with multiple myeloma.
Dexamethasone is a potent synthetic member of the corticosteroid. It is given to cancer patients undergoing chemotherapy to counteract emetic side effect and essential drug for the chemotherapy-treated patients. Hiccup is common adverse effect of corticosteroid especially on dexamethasone varying from 3% to 60% of given patients. Discontinuance of dexamethasone relieves most hiccupping cases, but vomiting/nausea rates increase. It is not clear whether hiccup side effect is limited to the dexamethasone only or other corticosteroid group. Methylprednisolone, synthetic corticosteroid as similar as dexamethasone, could be considered as antiemetic agent for the patients with receiving chemotherapy. The investigators perform this pilot study under hypothesis that replacing dexamethasone with methylprednisolone could maintain antiemetic role and prevent hiccup.
