Common diabetes drug successfully used to treat pituitary tumor

Using a common diabetes drug, researchers in Los Angeles have successfully treated pituitary tumors that cause a potentially life-threatening condition known as Cushing's syndrome. The most common type of Cushing's syndrome is caused by prolonged high-level exposure of a hormone called ACTH (adrenocorticotropin), which is secreted in excess by tumors of the pituitary gland, situated at the base of the brain and, which controls growth, metabolism and reproduction. Although the disorder is rare, it affects more women than men by a ratio of 5:1. Symptoms include weight gain with rounding of the face; increased fat in the neck; thinning skin; excess hair growth on the face neck, chest abdomen and thighs; muscle weakness and bone loss (osteoporosis); high blood sugar; diabetes; and high blood pressure.

Enzyme replacement effective in treatment of 'Fabry' disease

A disorder in which the body fails to make a particular enzyme --- leading to severe pain in the hands and feet, and eventual damage to internal organs --- has been successfully treated for the first time in Los Angeles.

Neural stem cells used to hunt, kill brain cancer

Using neural stem cells to hunt down and kill cancer cells, researchers have successfully tested a new treatment for brain cancer. They now hope the technique will lead to an effective treatment for glioma, the most aggressive form of primary brain tumor in humans. As the Cedars-Sianai researchers note, the prognosis has historically been extremely poor for patients diagnosed with malignant gliomas. The tumors have poorly defined margins, and glioma cells often spread deep into healthy brain tissue making their surgical removal difficult. Often, pockets of tumor cells break off from the main tumor and migrate deep into non-tumorous areas of the brain. Therefore, even if the original tumor is completely removed or destroyed, the risk of recurrence is high as cells in these distant "satellites" multiply and eventually re-form a new brain tumor. Due to these characteristics, treating brain cancer has been extremely difficult.
