A double-blind comparison of granisetron and placebo for the treatment of acute migraine in the emergency department.

Three hundred and ninety-seven patients who presented to the emergency department were screened for a randomized, double-blind, placebo-controlled study of iv granisetron (40 micrograms/kg or 80 micrograms/kg) in acute migraine. Twenty-eight patients fulfilled the stringent eligibility criteria and completed the study. Rescue medication was required 2 h post-infusion in 8 of 10 patients receiving granisetron 40 micrograms/kg, 5 of 10 patients receiving granisetron 80 micrograms/kg, and 6 of 8 patients receiving placebo. Significant improvement (p less than 0.05) in headache pain (on a visual analogue scale and categorical scale) was observed in the 80-micrograms/kg group. Headache pain evaluated with the Hunter headache scale indicated improvement for the sensory and affective components of headache pain in both granisetron groups. Except for more nausea at 30 min in the placebo group, no significant differences were noted between treatments. All three treatments were well tolerated. Granisetron may be effective for acute migraine headache; however, further studies with increased patient numbers are required.

Breast cancer metastatic to the eye is a common entity.

Breast cancer metastatic to the eye is a common entity occurring in up to 30% of women with metastatic disease. The prevalence of this lesion is not appreciated because of the dominant clinical picture of metastases occurring in other organs. The diagnosis should be suspected in any women with a history of breast cancer and any visual symptoms, particularly metamorphopsia and scotomata. A thorough ophthalmologic evaluation, aided by ultrasonography, computed tomography, or magnetic resonance scanning, usually confirms the diagnosis. Early treatment with radiation therapy can alleviate symptoms and control local disease. The recognition and treatment of this disorder is important in maximizing the quality of life in patients with metastatic breast cancer, especially because newer treatment regimens prolong survival and thereby increase the chances for ocular metastasis.
