RESUMO
Recent reports have focused on a possible association between migraine and Menière's disease; patients suffering from Menière's disease present a higher rate of migraine. In some cases, the clinical features of migraine-associated vertigo may mimic the presentation of Menière's disease. The present report focuses on two cases of females with recurrent episodes of rotational vertigo, fluctuating hearing loss and tinnitus lasting from a few minutes to several hours; both cases also presented migrainous attacks. As a result of repeated cochleovestibular attacks, both patients presented a permanent low frequency sensorineural hearing loss. Preventive therapies for Menière's disease did not reduce vertigo attacks, while topiramate and acetylsalicylic acid treatment resulted in a significant reduction of both migraine and vertigo. Both the diagnosis of Menière's disease and of migraine-associated vertigo rely on clinical history and both disorders lack a specific diagnostic test. In the early stages, differential diagnosis between Menière's disease and migraine-associated vertigo is often very difficult; previous investigations focused on the possibility that subjects with migraine may experience all symptoms of Menière's disease, including sensorineural fluctuating hearing loss. In conclusion, a trial with prophylactic drug treatment for migraine might be suggested in patients with clear symptoms of migraine and recurrent cochleovestibular disorders.

OBJECTIVES: To assess the efficacy of rehabilitation for dizzy patients after recent acute vestibular disturbance. METHODS: Forty patients recently hospitalised for an acute episode of rotational vertigo which lasted days were randomly divided into two groups. The first group (20 patients; group R) underwent active rehabilitation, while the second group (20 patients; group C) were told only to 'perform their daily activities'. Group R subjects underwent a total of 10 sessions of rehabilitation, including exercises on a stabilometric platform, point de mire and a series of five exercises repeated five times daily. All patients performed static stabilometry (posturography), undertook the dynamic gait index test, and completed a dizziness handicap questionnaire and a visual analogue scale for anxiety, at baseline and on completion. RESULTS: At 25 days, the rehabilitated patients obtained better results for all recorded outcomes, compared with the control group. The greatest difference in the rehabilitated subjects, compared with the control group, was for the dynamic gait index test; however, this difference was not statistically significant. The visual analogue scale anxiety score was statistically significantly more reduced in rehabilitated patients compared with control patients. Control patients maintained a higher visual dependence for postural control. CONCLUSIONS: These results would appear to support the effectiveness of a supervised exercise programme for patients following acute onset of vestibular disturbance. A correlation was found in both groups between dynamic gait index results and anxiety. In our experience, a rehabilitation programme seems to reduce dependence on visual cues for postural control.

The synthesis of DOTA tris(phenylmethyl) ester 2, a new monoreactive derivative of DOTA, is described. This versatile synthon can be easily coupled to compounds bearing an amino group and then deprotected to DOTA monoamide under mild and neutral conditions by catalytic hydrogenolysis. Accordingly, compound 2 has been used in the synthesis of a DOTA monoamide gadolinium complex containing two palmitic esters, which is a component of mixed micelles as MRI contrast agents.
