Abstract
A patient with alcohol-sensitive spontaneous, action- and stimulus-sensitive generalized reflex myoclonus is reported. Gait was abnormal but could not be clearly classified as dystonic. No other neurological abnormality was present. The possible relationship between alcohol-sensitive myoclonic dystonia and this case is discussed. Reflex myoclonus may serve as an additional clinical marker in the study of families with alcohol-sensitive myoclonus, dystonia, or both.

Abstract
Several types of cognitive and neuropsychological evidence suggest that priming effects on such implicit memory tests as word identification are mediated by a pre-semantic visual word form system that can operate independently of episodic memory. We investigate priming in a letter-by-letter reader, P.T., whose pattern of performance on neuropsychological tests indicates preservation of the word form system. Experiment 1 revealed robust priming on a word identification test following letter-by-letter study of target words, despite P.T.'s great difficulty in identifying non-studied words. Experiment 2 showed that the priming effect was modality specific whereas Experiment 3 indicated that recall of previously studied words was not modality specific, thus indicating that the observed priming could not be attributed to explicit memory strategies. Experiment 4 revealed no priming of illegal nonwords on a letter identification test. The results support the notion that priming on the word identification test depends on access to the word form system.

Abstract
Both Doppler supraorbital examination (OSM) and oculoplethysmography (OPG) were administered to 101 patients (202 arteries) to document the presence or absence of hemodynamically significant lesions of the internal carotid artery prior to angiography. There was no significant difference between the OSM and OPG with respect to diagnostic sensitivity or specificity, incidence of false-negative or false-positive results, and overall diagnostic accuracy. The diagnostic accuracy for the OSM and the OPG were 94.2% and 91.6%, respectively. In 171/202 (84.6%) arteries, the OSM and OPG were in diagnostic agreement, and the overall diagnostic accuracy of the combined tests was 97%. However, when the OSM and OPG did not agree (31/202 arteries, 15.4%), the diagnostic accuracy of neither the OSM nor the OPG was acceptable. Although the best diagnostic accuracy was obtained using two means of noninvasive cerebrovascular testing, in those instances where only one test may be available, the OPG would appear to be the test of choice. In those laboratories in which high diagnostic accuracy is obtained with the OSM, the addition of OPG testing will increase the overall diagnostic accuracy to a very high level. The presence of a midcervical bruit was found to have a very poor correlation with the incidence of hemodynamically significant stenoses of the internal carotid artery. Although both the OSM and OPG have minimal value in patients with symptomatic cerebrovascular disease, these tests play a very important role in screening patients for asymptomatic carotid stenosis or atypical cerebrovascular symptoms.

Abstract
The effect of general anesthesia on 42 multiple sclerosis (MS) patients who underwent 88 episodes of general anesthesia was analyzed. One patient experienced a relapse after a procedure under general anesthesia, which is compatible with the natural history of the disease. A literature review revealed little information on this subject or on the use of particular anesthetic agents in MS. Our experience with spinal and local anesthesia is reported. In the evaluation of the former our limited data suggested that spinal anesthesia is less preferable than other alternatives in MS. Local anesthetics had a benign effect on the course of MS.

Abstract
Cardiobacterium hominis, a recently recognized Gram-negative pathogen, was recovered in blood cultures from a 65-year-old man with indolent endocarditis of previously normal heart valves. Despite the low virulence of the organism, major cardiac damage required valvular replacement, and there were multiple cerebral emboli with development of a mycotic aneurysm. After bacteriological cure, he died of a ruptured aneurysm.

Abstract
The post-mortem examination of the brain of a 2 1/2-year-old girl with clinical featutes of oculo-auriculo-vertebral dysplasia and hemifacial microsomia (Goldenhar-Gorlin syndrom) revealed a unilateral absence of the olfactory foramina of the lamina cribrosa of the ethmoid bone and ipsilateral absence of olfactory bulb and tract. Other cerebral abnormalities were also present. In this report, unilateral arhinencephaly in this disorder has been documented for the first time and an attempt has been made to correlate various nosological, clinical and pathological aspects of the case with previously reported instances of arhinencephaly. It is concluded that unilateral arhinencephaly occurs in a variety of cranial and facial abnormalities and is not specific for any particular syndrome.
