Fukuyama type Congenital Muscular Dystrophy, inherited autosomal-recessively, is characterized by muscular dystrophy associated with severe mental retardation and epileptic convulsions. By examining 56 cases, followed for more than three years, 75 EEG records from 40 patients and visual evoked potentials from 11 patients with reference to autopsied materials, the authors aimed at clarifying the causative relationship between congenital central nervous system (CNS) lesions and childhood epilepsy. In 36 out of 56 cases diffuse epileptic seizures were observed with onset at 1.64 +/- 1.01 years average. In 32/36 cases seizures developed before 3 years of age. In 51/75 EEGs focal paroxysmal discharges (FPD), fronto-contro-parietal in younger and centro-occipital in older cases, were observed. Abnormal basic activities (ABA), diffuse-alpha-activity and/or abundant or extreme spindles, were observed more often in older than younger cases. The incidence of FPD was similar between convulsive and non-convulsive cases, but ABA predominated in the former, VEP revealed abnormal findings in 64% of 11 cases examined. Of the CNS pathology, consisting of cerebral and cerebellar gyral abnormalities and a hypoplastic corticospinal tract, the gyral lesions (verrucous polymicrogyria with adhesions of adjacent gyri and cellular disarrangement) were thought to be lesions causing epilepsy. Cortical nonprogressive gyral lesions occurring around the second trimester could cause FPD and clinical diffuse epileptic seizures develop with other factors concerned with ABA.

A total of 600 handicapped patients had dental rehabilitation under general anesthesia during an eight-year period. Handicaps included mental retardation, cerebral palsy, Down syndrome, seizure disorders, autism, cystic fibrosis, osteogenesis imperfecta, and muscular dystrophy. No significant complications developed in the majority of patients. This is attributed to thorough preoperative evaluation, appropriate anesthetic management, and vigilant postoperative observation.

Sleep-disordered breathing may occur in a wide variety of neuromuscular syndromes, and may present with diverse, often isolated, symptoms or findings such as excessive daytime sleepiness, pulmonary hypertension, congestive heart failure, morning headaches, or hypoxia-induced nocturnal seizures. The authors report two sisters with congenital muscular dystrophy in whom central sleep apnoea resulted in the isolated symptom of nocturnal seizures in one, and morning headaches in the other. Review of the literature reveals that sleep-disordered breathing may be common in neuromuscular disorders, and may often be present when clinical weakness is mild, and insufficient to result in diurnal respiratory dysfunction.

We report the case of an infant with facial dysmorphism, congenital hydrocephalus, severe hypotonia and absence of psychomotor development, with ocular and cerebral malformations consistent with the diagnosis of Walker-Warburg syndrome (WWS). Investigations included a cerebral CT scan indicative of type II lissencephaly and a muscular biopsy which showed findings of muscular dystrophy. The association of hypotonia, developmental delay and seizures with a neuronal migration disturbance and retinal involvement raised the suspicion of a peroxisomal disorder. The pertinent biochemical investigations, however, were negative. The features of this syndrome are reviewed, emphasizing the similarities with other related disorders as cerebro-oculo-muscular syndrome. We suggest that muscle involvement should be investigated in every case of WWS.

A case of a mediterranean boy with congenital muscular dystrophy (CMD) and central nervous system (CNS) involvement with mild intellectual impairment and seizures is reported. Muscular dystrophy involved both skeletal and mimic muscles, and histological findings were consistent with a congenital dystrophy. EEG recordings showed generalized and localized paroxysmal activities. CT scan demonstrated low-density periventricular areas. Ophthalmoplegia was also observed. A literature review disclosed that in some western cases of CMD plus CNS involvement, cranial muscles other than mimic muscles may be involved.

Phenytoin has a wide range of pharmacologic effects other than its anticonvulsant activity. It has been the subject of more than 8,000 published papers, which include clinical reports of its usefulness in approximately 100 diseases and symptoms. In the United States the only indications for use in the official labeling for phenytoin are various types of seizures. An advisory committee of the Food and Drug Administration recently recommended the addition of certain cardiac arrhythmias to the labeling. To determine whether other uses should be added to the labeling and whether additional clinical trials should be encouraged, an in-depth review of the published literature was undertaken. This review revealed that, on the basis of controlled studies, phenytoin is probably useful in the continuous muscle fiber activity syndrome, myotonic muscular dystrophy, and myotonia congenita. In addition, phenytoin appears to be potentially useful in recessive dystrophic epidermolysis bullosa, intermittent explosive disorder, anxiety disorder in which anger and irritability are prominent features, and, topically, in burns and refractory skin ulcers. Additional clinical studies are needed before definitive conclusions can be drawn. Clinical trials of phenytoin in most of these disorders are ongoing or are contemplated. Any labeling changes will await results of the studies. Based on phenytoin's pharmacologic effects in animals, controlled trials of the drug appear to be warranted in cerebral ischemia and stroke, spinal cord injury, angina pectoris, and fractures in which the rate of healing is poor.

Two spanish male brothers with weakness and muscular dystrophy and affection of the CNS are presented. Muscular disturbances were noticeable from birth and, although generalized, they affected more severely proximal muscles. Both children presented joint contractures from an early stage. None of the patients got to walk and to stand. Muscular serum enzymes were slightly elevated. EMG and muscular histology were compatible with conventional pathology of PMD. Other features of severe alteration of CNS were observed in both patients, being the most significant lack of sphincter control at 13 and 7 years old, mental retardation with an IQ about 70, generalized seizures at 10 years in the older boy and presence of brain alterations at computerized tomography (CT), consisting in low density on subcortical brain parenchima in both cerebral hemispheres and the cerebellum in the older brother and in both cerebral hemispheres in the younger. Clinical course is stationary in both brothers. It seems that in our patients there is an autosomal recessive heredity. All clinical, genetic, EMG, CT and histological features are compatible with congenital progressive muscular dystrophy of Fukuyama type.

A survey was made of the clinical characteristics of wheelchair-users at the Children's Rehabilitation Centre in Saskatoon, Saskatchewan. 261 patients were studied, of whom 214 had cerebral palsy, 34 had myelomeningocele and 13 had Duchenne muscular dystrophy. Among the patients with cerebral palsy it was found that the attributes likely to define a wheelchair-user were spastic quadriplegia, functional level III and IV, seizures and severe sensory handicap; among patients with myelomeningocele, wheelchair use ws related to level of lesion; and in the muscular dystrophy group it ws related to age. These results have been of help to rehabilitation centres and related service agencies in formulating long-term plans to meet the needs of wheelchair-users.

Central nervous system (CNS) characteristics were examined in seventeen patients with autosomal recessive classic or "pure" congenital muscular dystrophy (CMD). In three patients, neuroradiological examination (CT/MRI) indicated hypodense white matter areas. Two out of these three patients had epilepsy (seizures and epileptic discharges on their EEG). Only two of the remaining patients had epileptic EEG discharges, but without clinical seizures. By comparing our results to data in the literature, we could conclude that the classic or "pure" form of CMD can be subdivided into two subtypes, i.e. those with and those without white matter hypodensities. A mild form of epilepsy or an epileptic predisposition on EEG can be part of the subtype with white matter hypodensities.

We report clinical, EEG and neuroimaging findings of three patients in two Italian families with merosin-negative congenital muscular dystrophy (CMD), drug-resistant occipital epilepsy, diffuse persistent cerebral white matter changes and focal cortical dysplasia. Clinical and epilepsy histories, EEG and neuroimaging findings were very similar in all patients. Seizures started in childhood and mainly consisted of periodic spasms, a particular type of partial seizure characterized by clusters of epileptic spasms. The motor expression of the spasms was very mild so that they had been frequently missed or misinterpreted as non-convulsive generalized absence seizures. Interictal EEG showed occipital spike-waves and bilateral synchronous slow spike-wave discharges. Ictal EEG showed prolonged periodic sequences of slow waves with associated fast rhythm complexes, characteristic of periodic spasms. Two patients had normal intelligence, one patient presented moderate mental retardation. Focal cortical dysplasia in the posterior areas of the brain, in addition to marked diffuse white matter alterations, was detected in the magnetic resonance images of all patients. Findings in these patients indicate that in merosin-negative CMD brain involvement can include cortical dysplasia, in addition to white matter changes. In such cases the brain damage can lead to a childhood-onset localization-related symptomatic occipital epilepsy. Epileptic seizures and cortical dysplasia can be, however, difficult to detect in CMD. The clinical semiology of epileptic seizures may in fact be modified because of muscular weakness. This implies that epilepsy may be misdiagnosed or even missed and EEG-polymyographic recordings may be necessary to identify it. Similarly, cortical dysplasia may be very localized and visible by neuroimaging only if it is carefully investigated on the basis of epileptological and EEG-polymyographic findings.
