ABSTRACT
Cultivation of scientific research ability for postgraduates in neurosurgery department find expression in morality education, scientific spirit culture, scientific research objective propagan-da, review writing, data analysis and thesis writing, etc. Cultivation of scientific research ability and cultivation of clinical skill supplement each other and both can improve the research ability of post-graduates in neurosurgery department.
ABSTRACT
@#Objective To discuss the clinical characteristics, treatment and prognosis of pseudotumor forms of demyelinating diseases. Methods 21 patients with pseudotumor forms of demyelinating diseases diagnosed pathologically were analyzed retrospectively. Results 16 cases were operated on. The lesions were established through biopsy in other 5 patients. All the patients improved significantly after corticosteroid therapy. 4 patients relapsed after treatment, and 1 patient died. Conclusion The feature of pseudotumor forms of demyelinating disease is similar to some kinds of intracranial tumors, however it presents some radiological characteristics. Diagnostic corticoid therapy may be helpful to draw a diagnosis.
ABSTRACT
@#Objective To analyze and explore the clinical characterizations, treatment and prognosis of central neurocytoma (CNC).Methods The data of 62 cases of CNC from Jan 1995 to Jan 2008 confirmed by pathological examinations and underwent surgical treatment were analyzed retrospectively.Results CNC appeared some radiological figures.Conclusion Surgical resection with the help of post-operative radiotherapy can result in satisfied outcomes.
ABSTRACT
@#Objective To investigate the characteristics,treatment and prognosis of supratentorial parenchymal ependymomas(SPEs).Methods 16 cases with SPEs determined with pathology were reported.Results and Conclusion SPEs appears some figures different from other cerebral tumors.Surgery and radiotherapy can result in satisfied outcome.
ABSTRACT
@#Objective To observe the clinical efficacy and adverse reactions of high-dose methylprednisolone pulse treatment on peritumoral edema induced by supratentorial brain tumors.Methods Thirty-five patients with supratentorial brain tumors and peritumoral edema were treated with methylprednisolone pulse therapy before surgery and the edema index of every patient was calculated by MRI examinations before and after methylprednisolone treatment.Results After methylprednisolone pulse therapy, the edema indexes of the light, medium and severe edema patients reduced by 1.79%, 8.81% and 12.02% respectively. The edema indexes of the medium and serious patients were significantly lower than that before treatment ( P<0.01). But the edema index of the light edema patients was not significantly different with that before treatment ( P>0.05).Conclusion High-dose methylprednisolone pulse therapy has an obvious effect on medium and serious peritumoral edema induced by supratentorial brain tumors and has no serious adverse reactions.
ABSTRACT
@# ObjectiveTo investigate the role of intraoperative ultrasound (IOUS) in the surgical treatment of cerebral gliomas.MethodsThirty patients with primary supratentorial gliomas underwent microsurgery guided by intraoperative real-time ultrasound, IOUS was utilized for localization and delineation of the tumor as well as determination of the extent of resection.ResultsAll of 30 lesions were accurately defined by IOUS due to the distinct echogenicity compared with the normal brain. Solid low grade gliomas tended to be well circumscribed with regular sulcus, while central necrosis was most commonly present with malignant gliomas. Complete tumor extirpation was achieved by IOUS guidance in this group. Two patients exhibited mild neurological deficit following the surgery.ConclusionIOUS may provide valuable real-time information and facilitate effectual surgery with accuracy for the cerebral gliomas.
