Side effects of orally administered bismuthic salts have been known for many years. Many systems are involved, including the digestive and urinary. The authors discuss a recently discovered effect on the central nervous system, termed "bismuth encephalopathy". In the light of the medical literature reviewed, two original aspects are stressed: the clinical symptoms are stereotyped and completely reversible, and the distribution of the disease is almost epidemic, being limited in time and space. The prodromes include confusion, asthenia, slowing of mental functions and disturbance of gait. The clinical picture is dominated by four major symptoms: confusion (again), ataxia, dysarthria and, above all, myoclonic jerks. In conclusion, various pathogenetic hypotheses are considered. The purpose of this study is to enable the general practitioner to detect the development of this condition early in treatment with oral bismuthic salts. Withdrawal of the medication always results in normalization of the patient's condition.

We describe four men from two kinships affected with X-linked recessive bulbospinal neuronopathy, and one sporadic case. All developed postural tremor, weakness, and fasciculations, with onset from age 25 to 39 years. Weakness began in the pelvic girdle or hands, with dysphagia or dysarthria occurring years later in two. Sensory symptoms were present in only one, who also had diabetes mellitus. In contrast, sural nerve action potentials were small or absent in all. Needle EMG showed widespread chronic partial denervation with reinnervation. The characteristic twitching of the chin produced by pursing of the lips consisted of repetitive or grouped motor unit discharges, rather than fasciculations. Broader awareness of the distinctive features of bulbospinal neuronopathy will probably increase the frequency of its recognition. Diagnosis is important for purposes of providing a prognosis for affected men and genetic counseling for affected families.

A case of multiple sclerosis (MS) in a 39 year old Japanese female with high antibody titer to human T-lymphotropic virus type I (HTLV-I) in serum and cerebrospinal fluid (CSF) was reported. At the age of 15, gait and urinary disturbances accompanied by sensory impairment in the lower abdomen and lower extremities developed suddenly. The motor disturbance slowly progressed to tetraparesis over a period of 15 years with several remissions. At the age of 28 the patient suffered from an acute loss of visual acuity, unilateral initially, and became blind by the age of 34. On admission to our department in September, 1987, the patient was alert and had spastic paraparesis, the impairment of all sensory modalities below the level of Th 10 and urinary disturbance. Weakness of facial muscles, nystagmus, deviation of the tongue and dysarthria were also noted. By the PA method, the antibody titer to HTLV-I was measured x512 in the serum and x64 in the CSF. Western blotting analysis of the CSF disclosed the bands to p19, p24 and p28 of HTLV-I gag proteins. The CSF contained a few ATL-like atypical cells and showed mild lymphocytosis, but the total protein was not increased. The computed tomography revealed diffuse low density areas in the cerebral white matter. The magnetic resonance imaging disclosed high intensity signal areas in the cerebral white matter and in the dorsolateral portion of the medulla oblongata on the T2 weighted image. The link of HTLV-I infection to the pathogenesis of human demyelinating diseases was discussed.

We relate two cases of amineptine (Survector) overconsumption by patients cured for atypical depression with asthenia and activities deficit as the prevalent symptoms. Prescription of two tablets a day (0,200 g) was respected in one case during six months, and in the other case during two years, with therapeutic benefit on apragmatism. To no obvious reason, within few months both patients had gradually raised the doses to twenty tablets (2 g) and thirty tablets (3 g) respectively: we observed subexcitation, insomnia, sensorial hyperaesthesia, irritability, tachyphemia with dysarthria, anorexia with weight lost of more than 10 kg and amphetamine-like troubles without confusion or delusion, as a result of which both patients were treated for their addiction, in hospital. Treatment with clorazepate perfusions did not cause any physical dependence problems. However, psychological dependence was strong enough for one of the patients to go out, on the third day, against medical decision. As far as we know, in France, only one such case of addiction use at high doses and in single intakes is mentioned in the existing literature. However, our observations suggest that it might be necessary to re-assess the place of amineptine among new antidepressive molecules with psychostimulant abilities.

Motor function subserved by cranial nerves V, VII, X, XI, and XII was assessed in 100 patients with hemiparesis due to a unilateral vascular lesion of the cerebral hemisphere. Several of the findings were not described clearly in many of the standard textbooks of neurology. Weakness of sternomastoid when present was always contralateral to the hemiparesis. This emphasises the principle that the cerebral hemisphere controls movement of the body parts in or towards the contralateral half of the body rather than simply the contralateral muscle groups. An apparent exception to this was seen, however, in the small group of patients who had unilateral weakness of the tongue. In those patients deviation of the tongue was towards the hemiparetic side--that is, the cerebral hemisphere controlled the contralateral half of the tongue and hence protrusion towards the ipsilateral side. Mild dysarthria was common with both right and left sided hemiparesis.

We have retrospectively analysed the records of patients diagnosed as having myasthenia gravis and followed up in our department from February 1973 to March 1995. The main clinical findings were ptosis, diplopia, dysphagia, dysphonia or dysarthria, mastigatory impairment, dyspnea, asthenia, weakness of the cervical muscles and of the extremities, as well as findings of the physical and neurological examination. Based on the information collected, the patients were classified clinically according the modified Osserman-Gerkins scale, but considering the non-dynamic aspects of that scale, we used the modified functional scale of Niakan and classified the patients clinically as follows: remission, controlled, stable, partially controlled, poorly controlled, no response. We collected 153 patients, 104 (68.0%) females and 49 (32.0%) males producing a female/male ratio of 2.2:1. The duration of the disease varied from seven days to 27 years, mean 6.26 years (+/- 5.44). Age at the first symptoms varied between 24 hours to 80 years, mean of 32.13 years (+/- 19.48). We had 30 patients ranging from 0 to 15 years of age, 91 patients were observed between 15 and 50 years and 32 patients after the age of 50 years. Above the age of 60 years, the disease aflicts males more than females with a ratio of 1.5:1. The acquired autoimmune form with generalized weakness was the most frequent presentation. However, ocular muscle weakness with ptosis and diplopia were the most common clinical presentation in our series.

Weakness and fatigue in the orofacial system often are presumed to contribute to the dysarthria associated with neuromotor disorders, although previous research findings are equivocal. In this study, tongue strength, endurance, and stability during a sustained submaximal effort were assessed in 16 persons with mild to severe Parkinson disease (PD) and a perceptible speech disorder. The same measures were taken from one hand for comparison. Only tongue endurance was found to be significantly lower in these participants than in neurologically normal control participants matched for sex, age, weight, and height. Analyses of data from a larger sample comprising the present and retrospective data revealed lower-than-normal tongue strength and endurance in participants with PD. No significant correlations were found between tongue strength and endurance, interpause speech rate, articulatory precision, and overall speech defectiveness for the present and previously studied participants with PD, bringing into question the influence of modest degrees of tongue weakness and fatigue on perceptible speech deficits.

It is generally believed that the supranuclear innervation of the hypoglossal nucleus is bilateral and symmetrical. The aim of this work is to study the frequency and clinical characteristics of supranuclear tongue palsy in unilateral stroke. 300 patients with acute unilateral ischaemic motor strokes (excluding those in the lower brainstem) and an equal number of normal controls were studied for the presence of tongue deviation in a standardised manner. 29% of stroke patients and 5% of controls had tongue deviation (p < 0. 00001). Deviation was always to the side of the limb weakness. In patients with a history of stroke, it occurred more frequently in those with previous stroke on the contralateral side. Tongue deviation was most common in patients with clinical features of the non-lacunar stroke subtype (56%) or in those with cortical or large subcortical infarctions on brain CT scan (55 and 45%, respectively). All tongue deviations were associated with supranuclear 7th nerve palsy. Dysphagia and dysarthria occurred in 43 and 90% of patients with tongue deviation. Weakness of the arm was significantly associated with presence of tongue deviation. Tongue deviation in unilateral stroke most likely results from asymmetrical supranuclear control of the 12th cranial nerve in many individuals. The finding that it occurs relatively commonly in large (non-lacunar) infarcts and its association with dysphagia may have clinical utility.

Balancing tolerability and efficacy of medications can be problematic for clinicians when assessing appropriate therapy for patients. For antipsychotic therapy, this can be especially challenging because of the hazardous movement and metabolic effects associated with them. Paliperidone is an atypical antipsychotic used for the treatment of schizophrenia and schizoaffective disorder. A systematic review of the literature for the tolerability of the drug, paliperidone, was performed. A total of 15 articles met the criteria for inclusion representing a total of 3779 patients. Data combination was conducted using the Mantel-Haenszel method, random effects model at 95% confidence. Adverse events with the greatest incidence in the paliperidone population were any treatment emergent adverse event (68%), extra-pyramidal symptoms (23%), headache (14%), insomnia (11%), somnolence (9%), tachycardia (9%) and weight gain (8%). Reported events most likely related to paliperidone [largest attributable risks (AR)] were extra-pyramidal symptoms (AR=10), reduction in acute psychosis (AR=8), any treatment emergent adverse event (AR=6), tachycardia (AR=4), and weight gain (AR=4). Events where incidence was entirely because of paliperidone (incidence equals AR) were hypersalivation (3), dysarthria (2), and sexual dysfunction (1). Reported events totally unrelated to paliperidone (AR=0) included anxiety, asthenia, constipation, depression, dyspepsia, glucose related events, and vomiting. Overall, a 50% reduction in treatment emergent psychosis was seen in schizophrenic patients treated with paliperidone, however the reduction of a psychotic event is about equal to the occurrence of an adverse event with paliperidone.
