Induction of cyclooxygenase-2 expression by interleukin-1beta in human glioma cell line, U87MG.

Cyclooxygenase-2 (COX-2) is up-regulated in most high-grade gliomas, and high COX-2 expression is associated with aggressive character and poor prognosis. However, the effect of COX-2 in human glioma cell lines is not well known. This study examined the effect of several stimuli, including interleukin-1beta (IL-1beta) and carcinogens, on COX-2 induction in normal astrocyte cells and human glioma cell lines U87MG, A172, and T98G.

Metastasis of carcinoid to the arch of the axis in a multiple endocrine neoplasia patient: a case report.

Background Context: Carcinoid tumors eventually metastasize to the spine, and epidural spinal cord compression is a relatively frequent neurologic complication of carcinoid. However, a case of multiple endocrine neoplasia type 1 (MEN1) presenting with spinal cord compression as a result of a metastatic carcinoid tumor has not been reported previously.

Purpose: To report an extremely rare case of MEN1 presenting with spinal cord compression by metastatic carcinoid tumor.

Metastatic hemangiopericytoma to the cauda equina: a case report.

Background Context: Hemangiopericytoma is an aggressive tumor associated with high recurrence and metastasis. Metastases are usually delayed, long after diagnosis of the primary lesion. Metastatic hemangiopericytoma to the spinal cord is especially rare.

Cerebral venous sinus thrombosis associated with iron deficiency: two case reports.

Two patients presented with cerebral venous sinus thrombosis (CVST) associated with iron deficiency. A 14-year-old man had thrombosis extending from the end of the superior sagittal sinus to the left transverse sinus. Severe dehydration after competitive sport had induced CVST.
