Cantharidin, known popularly as Spanish fly, has been used for millennia as a sexual stimulant. The chemical is derived from blister beetles and is notable for its vesicant properties. While most commonly available preparations of Spanish fly contain cantharidin in negligible amounts, if at all, the chemical is available illicitly in concentrations capable of causing severe toxicity. Symptoms of cantharidin poisoning include burning of the mouth, dysphagia, nausea, hematemesis, gross hematuria, and dysuria. Mucosal erosion and hemorrhage is seen in the upper gastrointestinal (GI) tract. Renal dysfunction is common and related to acute tubular necrosis and glomerular destruction. Priapism, seizures, and cardiac abnormalities are less commonly seen. We report four cases of cantharidin poisoning presenting to our emergency department with complaints of dysuria and dark urine. Three patients had abdominal pain, one had flank pain, and the one woman had vaginal bleeding. Three had hematuria and two had occult rectal bleeding. Low-grade disseminated intravascular coagulation, not previously associated with cantharidin poisoning, was noted in two patients. Management of cantharidin poisoning is supportive. Given the widespread availability of Spanish fly, its reputation as an aphrodisiac, and the fact that ingestion is frequently unwitting, cantharidin poisoning may be a more common cause of morbidity than is generally recognized. Cantharidin poisoning should be suspected in any patient presenting with unexplained hematuria or with GI hemorrhage associated with diffuse injury of the upper GI tract.

We described a 12-year-old girl with systemic lupus erythematosus (SLE) associated with myasthenia gravis (MG). She had absence seizures from 6 years old. She admitted to our hospital at 12 years of age because of absence seizures and dyspnea. The diagnosis of SLE was made on the basis of convulsion, arthritis, pleurisy, and positive antinuclear factor and was started therapy with prednisolone. The clinical course was complicated by the appearance of dysphagia and hoarseness. On the basis of positive Tensilon test and a high level of serum anti-acetylcholine receptor antibody, we made a diagnosis of the systemic type of MG. Her condition was improved by methylprednisolone pulse therapy and gamma-globulin therapy after plasmapheresis. The association of early-onset SLE with MG is rare.

Congenital bilateral perisylvian syndrome (CBPS) is a recently described, neuronal migration disorder, characterized by pseudobulbar palsy, epilepsy and mental retardation and bilateral perisylvian dysplasia. A 15-year-old boy was diagnosed with CBPS according to the typical clinical, and magnetic resonance imaging (MRI) features. The patient was suffering from atypical absence seizures, repeating daily in spite of antiepileptic drug therapy, since age 7 years. He had also experienced rare generalized tonic-clonic seizures and complex partial seizures. Neurological examination showed severe restriction of tongue movements, severe dysarthria, dysphagia, facial diplegia, mild pyramidal signs and moderate mental retardation. A computed tomographic (CT) scan demonstrated bilateral perisylvian enlargement. The diagnosis was corrected with MRI after six years. Frequent irregular generalized spike and wave abnormalities and focal sharp and slow waves over the posterior regions of both hemispheres were shown by electroencephalograms (EEG). The patient was treated with Na-Valproate, carbamazepine and lamotrigine but did now show any significant change in seizure frequency in the eight-year follow-up period. Intractable seizures, mental retardation and particularly congenital pseudobulbar palsy suggest this congenital entity. Those patients who exhibit these typically clinical features, must have MRI.

This self-directed learning module highlights new advances in the understanding of co-morbid conditions and medical complications of stroke. It is part of the chapter on stroke rehabilitation in the Self-Directed Physiatric Education Program for practitioners and trainees in physical medicine and rehabilitation. This article covers co-morbid conditions of stroke patients, including cardiovascular disease, diabetes, and sleep apnea. It reviews recent information on complications of stroke, including deep venous thrombosis, dysphagia and aspiration, hospital-acquired infections, depression, falls, spasticity, shoulder pain, and seizures. Treatment advances in diabetes, depression, and spasticity are highlighted. Recent information is presented regarding exercise guidelines for the stroke patient with cardiovascular disease, the relationship between stroke and sleep apnea, prophylaxis of deep venous thrombosis, the changing spectrum of hospital-acquired infections, malnutrition in stroke patients, the problem of falls during rehabilitation, the evaluation and management of poststroke shoulder pain, and the risk of seizures after stroke.

This study reports on a girl with a permanent cerebral lesion and opercular syndrome after status epilepticus (SE). She had previously been healthy and had her first focal motor seizure at 5 years of age, which was controlled with intravenous phenytoin and rectal diazepam. Twenty-four hours later, she developed partial SE consisting of right facial twitching and right-hand clonic movements. These uncontrollable seizures lasted for 5 days, after which the partial SE changed to generalized SE, and the seizures continued for another 5 days. CT performed the day before onset of SE revealed no brain abnormality. Another CT performed a year later disclosed bilateral brain lesions, more severe in the left hemisphere. Follow up at 16 years of age revealed moderate motor sequelae of the right-hand side of the body, anarthria, difficulty chewing, dysphagia, bilateral facial weakness, and drooling, all of which clinically characterize opercular syndrome. An MRI study performed at 14 years of age showed a cerebral parenchymatous lesion which extended between the parietal cortices of both hemispheres, more severe on the left side, and which crossed the corpus callosum, destroying the posterior-middle zone. Evidence from the CT indicates that the lesion was not present before onset of SE. It seems likely that the focal SE caused the focal brain damage, but the possibility that the subsequent generalized SE played a role cannot be excluded.

X-linked adrenoleukodystrophy is a progressive neurodegenerative disorder involving the destruction of white matter in the brain and adrenocortical hormone deficiency. Clinical symptoms first appear between 4 and 8 years of age and include spasticity, visual loss, dysphagia, and seizures. In this report, continuous infusion of intrathecal baclofen was used to treat the severe spasticity of an 8-year-old patient with X-linked adrenoleukodystrophy. The improvement in this patient's quality of life, including the elimination of pain and the increased ease of care, suggests that intrathecal baclofen should be considered as part of the treatment strategy for spasticity associated with X-linked adrenoleukodystrophy and other neurodegenerative disorders in children and adults.

We report here a girl aged 5 years 3 months with cryptogenic localization-related epilepsy who showed a prolonged episode characterized by dysarthria, dysphagia, drooling and paresis of the right arm associated with almost continuous diffuse sharp-slow wave complexes during sleep. These symptoms were not directly related to seizures or to each sharp-slow wave complex revealed by examination during the video electroencephalographic (EEG) recording. The interictal single photon emission compute tomography showed a localized high perfusion area in the left posterior frontal region. The introduction of clonazepam completely controlled the clinical symptoms as well as the EEG abnormality within 2 weeks. After 4 months of remission, a similar episode recurred which was associated with aggravation of EEG. The clinical and EEG characteristics of this patient were identical to those of acquired epileptiform opercular syndrome (AEOS), a newly proposed epileptic syndrome, in which a transient operculum syndrome develops in association with continuous spike-and-wave activity during slow sleep (CSWS). Computer-assisted EEG analysis demonstrated that the epileptic EEG focus was located in the left sylvian fissure, and produced secondary bilateral synchronous sharp-slow complexes. The present study further supports the hypothesis that the electrical interference by CSWS creates bilateral opercular dysfunction through the mechanism of secondary bilateral synchrony, thus producing AEOS.

A long-term follow-up study of Lennox-Gastaut syndrome (LGS) ( > 10 years) was conducted with 38 patients with severe motor and intellectual disabilities (SMID) to clarify the relationship between the rapid development of dysphagia and epileptic seizures, and to elucidate the long-term evolution of LGS in patients with SMID. Those who showed a relatively favourable seizure outcome were compared to those with a poor seizure outcome. Poor seizure outcome correlated strongly with: (a) an early appearance of dysphagia and additional deterioration of the already retarded mental function; (b) a predominance of atypical absence seizures; and (c) persistent frequent epileptiform discharges during electroencephalographic evaluations. Neither age at seizure onset nor intelligence level at the time of the last examination was correlated with seizure prognosis. Further, seizure prognosis was not related to the aetiology of LGS. Repeated seizures apparently caused development of progressive epileptic encephalopathy, in addition to the underlying severe brain damage. Since development of dysphagia burdens an already severely handicapped patient with intensive medical care, efforts to reduce the seizures and design a long-term care plan are of great importance.

The term acanthocytosis is derived from the Greek for "thorn" and is used to describe a peculiar spiky appearance of erythrocytes. Acanthocytosis is found to be associated with at least three hereditary neurological disorders that are generally referred to as neuroacanthocytosis. Abetalipoproteinaemia is an autosomal recessive condition, characterised by absence of serum apolipoprotein B containing lipoproteins leading to fat intolerance and fat-soluble vitamin deficiency. This results in a progressive spinocerebellar ataxia with peripheral neuropathy and retinitis pigmentosa. Chorea-acanthocytosis is also an autosomal recessive condition and is characterised by chorea, orofaciolingual dyskinesia, dysphagia, dysarthria, areflexia, seizures and dementia. Some of its features, including choreic movements, peripheral neuropathy with areflexia, elevated serum creatine kinase levels and myopathy are shared by another form of neuroacanthocytosis, McLeod syndrome. Patients affected by this X-linked disorder also show abnormal expression of Kell blood group antigens and a permanent haemolytic state. In addition to these cases, acanthocytosis is occasionally associated with other neurological disorders, such as Hallervorden-Spatz disease. For each of the neuroacanthocytosis syndromes we review the main clinical features and their molecular bases. The recent molecular genetics findings are the first step towards the understanding of the pathogenetic mechanisms and eventually the search for effective treatments.

We observed two families with a dominantly inherited complex neurological syndrome with onset in adulthood. Family F included 9 affected in four generations. One patient showed prominent anticipation of onset age. Onset was with cerebellar signs followed by dementia, psychiatric symptoms, seizures, and extrapyramidal features. Family M included 14 affected individuals in five generations. Presenting symptoms were either psychiatric and cognitive impairment or a cerebellar syndrome. Extrapyramidal features, dysphagia, incontinence, seizures, and myoclonus may occur. In both families magnetic resonance imaging showed marked atrophy of the brain and cerebellum. Molecular analyses demonstrated an expanded CAG/CAA repeat in the in the TATA box-binding protein (TBP) gene (SCA17).
