A study of Gulf War veterans with a possible deployment-related syndrome.

A previous symptom-based survey of veterans of the 1990-1991 Persian Gulf War suggested a neurological syndrome (blurred vision, loss of balance/dizziness, tremors/shaking, and speech difficulty). The authors conducted the present study to determine whether specific findings could indicate an organic basis for this possible syndrome. They completed an extensive clinical and laboratory evaluation on Gulf War veterans with all 4 symptoms, using 3 comparison groups.

Petroclival meningiomas: multimodality treatment and outcomes at long-term follow-up.

Objective: To evaluate patients' clinical outcome, survival, and performance status, at the long-term follow-up evaluation after aggressive microsurgical resection of petroclival meningiomas.

Methods: During a 13-year period (1991-2004), 150 patients underwent 207 operative procedures for resection of petroclival meningiomas. The tumor size was large in 79% of the patients, with a mean tumor diameter of 3.
