A European head injury evaluation chart.

In 1988, 40 experts (physicians, psychologists, social workers, lawyers, family association representatives...) coming from the E.E.C., the United States, Canada and Sweden met in Brussels to derive the guidelines for a minimal assessment of head injured people. This workshop led to a research contract between E.B.I.S. (European Brain Injury Society) and the E.E.C. Directorate for Science regarding a European evaluation document. The aims of the document are both clinical and scientific. Hence the document has to be simple, specific and feasible. The document has two parts: initial state and repeated follow-up. It ends with final comments and action plan. The first statistical data of the validation study concern mainly the link between initial severity of injury and final handicap, cognitive and behavioural troubles, familial and professional aspects of handicap.

[Traumatic amnesias. Memory disorders consecutive to head injuries].

Traumatic amnesia is a good index predictive of the disablement due sequelae of cranial injuries. The residual memory deficit, correlated with the return to work, mainly affects long-term memory, learning, verbal memory and sensitivity to interferences. The most relevant tests are Rey's 15 words--and particularly their retrieval at 30 minutes--and the verbal fluency test, but the changes in memory observed in the patient's daily life must also be evaluated. Rehabilitation tends to rely on the overall management of intellectual and behavioural disorders, as part of programmes that are specific to subjects with cranial injury.

[Familial distal progressive spinal amyotrophy with asymmetry of the lower limbs].

Two cases of spinal muscular atrophy, localized on the lower limbs and strictly unilateral, in two half brothers, are reported. Such a distribution of clinical changes and such a hereditary transmission appear to be unusual in hereditary motor-neuronopathies. A recessive heterotopic transmission may be suspected. To our knowledge, it has been reported in Kennedy's disease only.

[Focal chronic ischemia and concomitant migraine: an atypical form of Sturge-Weber angiomatosis?].

A young man with a left hemifacial hemangioma had during a six months period about forty left hemispheric neurologic attacks suggestive of classic migraine. The neurologic examination was normal during the attack-free period. The CT scan (fig. 1) and the M.R.I. study (fig. 2) only showed a moderate interhemispheric asymmetry. The left internal carotid angiogram showed subtle anomalies of the venous system (fig. 3). All the neurologic manifestations ceased as soon as therapy by aspirin was initiated. A Positron Emission Tomography (PET) study with the oxygen 15 continuous inhalation technique was performed 7 months after the last attack in order to measure the regional Cerebral Blood Flow (rCBF), Oxygen Extraction Fraction (rOEF) and Oxygen Consumption (rCMRO2). Striking, statistically significant, alterations were observed in the left temporo-parieto-occipital area (fig. 4) consisting of a "misery perfusion" syndrome (rCBF = 28-38 ml/100 g/mn; rOEF = 0.64-0.80), without alteration in the rCMRO2 (Table). A repeated PET study 12 months later was unchanged. The association of local chronic oligemia and ipsilateral facial hemangioma, ipsilateral cerebral hypotrophy and venous anomalies suggested the diagnosis of atypical leptomeningeal angiomatosis of the Sturge-Weber type. The importance and persistence of the hemodynamic alterations suggest that chronic oligemia and, hence, tissue hypoxia may participate in the pathogenesis of the migraine-like attacks. Moreover, local circulatory stasis with thrombotic events may be implicated, as suggested by the apparent efficacy of aspirin.

[Intellectual and mood disorders in multiple sclerosis].

Reports of frequency and interpretation of intellectual and mood disorders differ in multiple sclerosis (MS). Forty-one patients with MS defined according to MacAlpine's criteria were evaluated by psychometric tests (WAIS) and neuropsychologic examinations (study of language, gnosic and praxic activities, dynamic gestural organization, memory and learning) together with, in 24 of them, the AMDP psychopathologic rating scale. Intellectual disorders were noted in 65 p. 100 of patients. Although more frequent in severe and chronic forms they were nevertheless of early onset since more than a half of the patients with onset of disease less than 5 years ago were affected. Their semiology was fairly homogeneous, combining disturbances of dynamic gestural organization (decomposition or simplification) and memory and learning deficiencies without anomalies of instrumental functions or usual psychometric mental deterioration. Application of the AMDP scale failed to reveal any psychotic type of disorders. Mood disturbances were predominant, affecting 60 p. 100 of the subpopulation studied (24 cases) and combining, in an unexpected manner: dysphoria, euphoria and depression. Only euphoria appeared to be correlated with intellectual disorders. Frequency of both intellectual and mood disorders was similar to that reported in other series published. The relative homogeneity of semiology, seen by the correlation between the different disturbances (decomposition and simplification, plateau learning curve and euphoria) and the unusual grouping of these effects, is suggestive of their organic basis. In addition, signs and symptoms resemble the neuropsychological expression of frontal lobe lesions and certain lesions of central grey nuclei.(ABSTRACT TRUNCATED AT 250 WORDS)

[Piribedil, dopaminergic agonist. Prolonged clinical and electrophysiological study in 60 parkinsonian patients (author's transl)].

Sixty cases of Parkinson's disease were treated with piribedil alone (dose : 274 mg/day, duration : 20,4 months). The overall clinical improvement, confirmed by recordings of tremor and EMG, was 34%, tremor being improved of 59%. Before treatment, an intravenous test does of piribedil with recording made it possible to predict the effectiveness of oral treatment. Side-effects (vasomotor, digestive, psychiatric) were moderate. Orthostatic hypotension, dyskinesia and fluctuations were exceptional. The basic indication for piribedil lies in forms of recent onset in which tremor predominates, patients in whom L-dopa is contraindicated and a certain number in whom the latter has failed (tremor, fluctuating action).

[Hodgkin's granuloma of the cerebral hemisphere. Apropos of one case].

With reference to a case of Hodgkin's granuloma of the frontal lobe, a review of the literature has enabled 8 similar cases of intra-cerebral localisation of this disease to be reclassified. Their mechanism is discussed on the basis of neuropathological data and in particular their development in situ. Excision of the lesion appears to be the treatment of choice.

[Polygraphic recording of tremor and of hypertonic phenomena. Application to the action of various drugs].

The recording technique described makes possible the detailed analysis of hypertonia and tremor in Parkinson's disease, as well as the action of different drugs. It may contribute to the understanding of the physiopathological basis of these motor disturbances and the mode of action of anti-parkinsonian drugs. It also represents a reliable method of repeated observation, independent of subjective factors, in the evaluation of the long-term effectiveness of a medication. We were particularly concerned with the evaluation and comparison of the effect of different drugs in the course of a short study, involving the administration of a single dose of the medications used. In this way were studied: Apomorphine, given sub-cutaneously in non-emetic doses, which decreases in a constant and spectacular fashion both tremor and hypertonia ; Piribedil (1-3 mg IV) ; L-Dopa (100 mg IV) ; Ro-080576/007 F in a dose of one capsule containing 200 mg of L-Dopa and 50 mg of L-dopa-decarboxylase inhibitor. The effect of these various medications was invariable greater than that of a placebo and lasted much longer. With these doses, and under the special experimental conditions of this study, Piribedil was better tolerated and in general more active than L-dopa, in particular in relation to tremor. The action observed in the course of this short study prior to treatment might, to a certain extent, make it possible to predict the effect of long-term treatment.

[Myoclonic encephalopathy due to bismuth following colectomy. Apropos of a case].

Bismuth encephalopathy mainly affects chronic constipation sufferers. The case described, which is practically identical, should be considered (in the absence of constipation) within the context of resection for cancer. The responsibility of bismuth, suggested in five similar cases by Burns and colleagues, is here confirmed by the blood, C.S.F. and urine levels. The mechanism of encephalopathy and the possibility of a failure to eliminate bismuth affecting these levels are discussed.
