ABSTRACT
The Detection of neurologic signs for topographical disorders in central nerves system can prevent unnecessary neuroimaging techniques such as MRI. This study was performed to determine the diagnostic value of physical examination for topographic detection of infratentorial lesions in patients with cerebrovascular syndromes. This descriptive study was done on 200 patients with cerebrovascular syndrome in Qaem Hospital in Mashhad, north-east Iran during 2011. Regarding to topographic physical examination, sensitivity, specificity, positive and negative predictive value and accuracy of signs of syndromes were compared to MRI as gold standard method. The accuracy of tetraparesis and crossed syndromes for localization of brain lesion in brainstem was 79% and 83%, respectively. The accuracy of hemiataxia for localization of brain lesion in ipsilateral cerebellar hemisphere was 98%. The accuracy of Wallenberg syndrome for localization of brain lesion in posterolateral medulla was 98%. Using clinical neuro-examination skills and accurate topographic physical examination can prevent unwanted MRI technique for the diagnoses of cerebrovascular syndromes
ABSTRACT
Nausea and vomiting of early pregnancy [NVP] are often alleviated by eating dried biscuits or food. Natural products such as ginger have been suggested as herbal medicine for its treatment. The purpose of this study was to determine the effectiveness of ginger in biscuit form for the treatment. This study was performed on 65 pregnant women with NVP before 17 weeks' gestation during 2004-2005. The subjects were randomized in a double-blind design and divided into two groups to take biscuits. Ginger [0.5 g] as fine powder was incorporated in each biscuit. Subjects received 5 ginger biscuits per day or an identical placebo biscuit for 4 days. They graded their severity of nausea using visual analog scales and recorded the number of vomiting episodes in the previous 24 hours and again during 4 consecutive days. Obtained data between two groups were compared using Mann-Whitney, Wilcoxon Sumrank and Kruskall-Wallis H tests. All subjects except 3 in the ginger group remained in the study. The visual analog scores of post-therapy minus baseline nausea decreased significantly in ginger [2.6 +/- 1.83] compared with the placebo group [1.4 +/- 1.97, p=0.015]. The number of vomiting episodes also decreased in ginger [0.96 +/- 1.2] and placebo group [0.6 +/- 1.4]. Ginger in biscuit form is effective for relieving the severity of nausea and vomiting of pregnancy
