Article: Bilateral ageusia caused by a unilateral midbrain and thalamic infarction.
[show abstract] [hide abstract]
ABSTRACT: BACKGROUND: Based upon scarce clinical data in humans and experimental findings in animal studies, it has been postulated that the ascending gustatory projection from the nucleus tractus solitarii courses ipsilaterally through the pons and midbrain to the ipsilateral ventral posteromedial nucleus. Thus, it has been assumed that ischemic lesions affecting the secondary projection gustatory fibers would cause ipsilateral taste disorders. DESCRIPTION OF CASE: We report a case of bilateral ageusia following an acute right midbrain and thalamic infarction affecting the ipsilateral central trigeminal tract and ventral posteromedial nucleus in a right-handed man. CONCLUSION: The present case indicates that, in contrast to animal data, some secondary projection gustatory fibers may cross in humans and consequently unilateral right-sided posterior circulation ischemic lesions can cause bilateral gustatory deficits.Journal of neuroimaging: official journal of the American Society of Neuroimaging 01/2011; 21(3):263-5. · 1.72 Impact Factor -
Article: The Greek version of the Quality of Life in Epilepsy Inventory (QOLIE-31).

ABSTRACT: This study is presenting the translation and cultural adaptation into Greek of the Quality of Life in Epilepsy Inventory (QOLIE-31). We adapted the QOLIE-31 to Greek through a procedure of translation-back-translation. Sixty-three patients were interviewed and completed the QOLIE-31 and the GHQ questionnaires. We re-examined a subset of them after a period of 2-5 weeks to evaluate the test-retest reliability of the questionnaire. We assessed the convergent validity by comparison of the QOLIE-31 and the GHQ and QOLIE-31 subscales and external measures. Discriminative validity was evaluated using the method of known-groups comparisons. The internal consistency was high for the QOLIE-31 and its' subscales (Cronbach's alpha 0.92 and 0.59-0.83 respectively). Test-retest reliability was acceptable (intra-class correlation coefficient 0.49-0.89 and Pearson's coefficient 0.53-0.92) for the group of patients who were re-examined. Comparison of the QOLIE-31 and GHQ scores showed agreement between the two questionnaires (Pearson's coefficient -0.61). We demonstrated the discriminative validity by the difference in the QOLIE-31 scores between patients with different seizure frequencies and different employment status. We concluded that the Greek version of the QOLIE-31 has psychometric properties equivalent to those of the original American-English version and is a valid and reliable instrument.Quality of Life Research 07/2006; 15(5):833-9. · 2.30 Impact Factor
