The French neurologists and psychiatrists who were mobilized during the Great War were confronted with numerous soldiers with war neuroses, often with novel clinical manifestations such as camptocormia. They addressed hysteria and pithiatism according to concepts that had been formed before the war, and many doctors considered these soldiers to be malingerers. As a result, the use of aggressive therapies to enable their prompt return to the battlefront was advocated. In 1915-1916, Clovis Vincent (1879-1947) developed a method called torpillage, a "persuasive" form of psychotherapy using faradic and galvanic electric currents, to treat soldiers with "intractable" neuroses. However, since the treatment was painful, soldiers began to refuse it and, following a publicized trial, the method was discontinued. Given the influx of soldiers with seemingly incurable neuroses, Gustave Roussy (1874-1948) made an attempt in 1917 to develop a new method of psychoelectric treatment. In January 1918, he too came up against soldiers refusing electric treatment. Following a new trial and an unfavorable press campaign, the psycho-faradic method gradually died out. These extreme medical practices developed to treat psychological trauma during the First World War subsequently led to the delineation of posttraumatic stress disorder in more recent wars.

Vulnerable individuals, lacking clear understanding, are difficult to inform about medical care and treatment. After a brief recall of the general principles of patient information and consent, we will discuss specific French law protection concerning patients under guardianship. The role in the global process of information and consent of either relatives or surrogate person, witnesses of the patient's views, will be described.

Body-packing has increased as a means of illicit drug transportation, particularly since the intensification of customs control and luggage inspection which followed the terrorist attacks of September 11, 2001. This mode of drug transport may result in intestinal obstruction or systemic intoxication; diagnostic measures are discussed; management may require specific precautions and occasionally surgical intervention. The problem of how to handle and dispose of large quantities of drugs removed from or passed by a patient who may not be under arrest presents specific medicolegal considerations.

Ataxic hemiparesis is commonly considered as one of the "typical" lacunar syndromes. Using the prospective stroke registries from Lausanne and Besançon, 100 patients were selected consecutively (73% men, 27% women; age 64.7 (SD 13.6) years) with a first stroke and ataxic hemiparesis (hemiparesis or pyramidal signs and ipsilateral incoordination without sensory loss). Brain CT or MRI was performed on all patients. A primary haemorrhage was present in 5%, an infarct in 72%, isolated leukoaraiosis in 9%, and no apparent abnormality in 14%. The locations of lesions were the internal capsule (39%), pons (19%), thalamus (13%), corona radiata (13%), lentiform nucleus (8%), cerebellum (superior cerebellar artery territory) (4%), and frontal cortex (anterior cerebral artery territory) (4%). The clinical features of ataxic hemiparesis with different locations were almost identical. Only minor associated signs allowed the localisation of the lesions (paraesthesiae with a lesion in the thalamus; nystagmus or dysarthria with a cerebellar or pontine location). Crural paresis with homolateral ataxia was seen only with cortical paramedian frontal lesions. Presumed hypertensive small artery disease was not always found, but was still the leading cause of stroke, being present in 59% of the patients and in 62% of those with small deep infarcts. A potential source of embolism (arterial or cardiac) was found in one fourth of the patients. Therefore no definite association can be made between ataxic hemiparesis and lacunar infarction. In particular, so called uncommon lesion locations may not be rare. After extensive investigations a diagnosis of lacunar infarct can be retained in only slightly more than half of the cases.

A review of hemorrhagic transformation after brain ischemia is presented. The pathological, clinical and radiological aspects are discussed with respect to recent studies. The different pathophysiological mechanisms (reperfusion, vascular rupture, size of infarction, timing of constitution) are reviewed. The role of the utilization of antithrombotic (anticoagulant and thrombolytic) agents in the production of hemorrhagic infarct is presented, and we propose a new classification of hemorrhagic infarct, based on the CT scan patterns.

Free-floating clots of the extracranial internal carotid artery are generally considered as surgical emergencies. This retrospective study analyzes six free-floating clots diagnosed by arteriography. Three of these patients had a fixed stroke while the other three had an evolving stroke. Three patients had antecedent ocular or hemispheric transient ischemic attacks. The causes of free-floating clots in the internal carotid artery were atheromatous stenosis in two cases, ulcerated plaque in three cases, and carotid artery dissection in one. All six patients were seen late, approximately 15 hours after their neurologic accident. They were treated with intravenous heparin over a two to five week period. Repeat arteriograms demonstrated complete clot lysis in four instances, while partial lysis was seen in one case. Moderate extension of thrombus occurred in one case only. No further neurologic complications were noted during the treatment by heparin. As indicated by follow-up arteriographic findings, secondary surgery was performed for major carotid lesions and residual clots in five cases. The free-floating thrombus syndrome of the carotid artery should not be considered as a surgical emergency when discovered late in the wake of an acute neurologic accident.
