We concur with the idea that congenital muscular dystrophy (CMD) is a distinct clinical entity, and report 17 patients (2 negroes and 15 whites; 12 M and 5 F; median age 6 years, range 1 to 24 years) with genetic, clinical, laboratorial, electrophysiological and histochemical studies. All our cases have an inheritance compatible with an autosomal recessive pattern. A decrease in fetal movements was reported by 57% of the mothers, generalized hypotonia at birth was present in 82%, limb girdle and neck weakness, absent or decreased deep tendon reflexes, and limb contractures were present in all. Severe muscular wasting was found in 41%. Calf pseudo-hypertrophy was observed in one patient. A patient was severely mentally retarded and another was borderline. During a 30-month follow-up, the muscle weakness of the majority remained essentially unchanged but the degree of motor activity deteriorated and was proportional to the worsening of the limb contractures. Serum CK levels were normal or increased to a maximum of 8 times. The electromyogram was myopathic in 74%, neurogenic in 13% and normal in 13%. CT scans showed a symmetrical white matter hypodensity in the hemispheres in 8 cases. All but 5 patients were operated upon to release the limb contractures and all were submitted to physical therapy. The contractures recurred in 4 patients submitted to surgery and were probably related to the cessation of physical therapy.

A term newborn male with severe hypotonia and contractures was found to have dense bilateral cataracts. He died at age 3 days of respiratory failure. Amino acidopathies and disorders of peroxisome function were excluded, and results of serologic studies and placental histopathology, specifically seeking evidence of intrauterine infection, were normal. Autopsy showed changes in the skeletal muscles consistent with congenital muscular dystrophy and a small focal anomaly of the cerebral cortex. These findings either represent a new syndrome or raise further questions about broadening the spectrum of known congenital muscular dystrophy syndromes with associated eye and brain anomalies.

We report cystinuria and symptoms of cerebellar atrophy in a 45-year-old man. His parents were first cousins, and many members of his family had stones of urinary tract or gait impairment. Neurological examination disclosed cerebellar signs resembling those of spinocerebellar degeneration. Urinalysis disclosed high cystine, lysine, ornitine and arginine output. Cystine was 1153.8 micro mol/day (normal range, 22-170); lysine, 3443.9 (normal range, 44-1000); ornitine, 283.8 (normal range, 7-40); and arginine, 154.0 (normal range, 9-50). Neurological complications reported to be associated with cystinuria include mental retardation, muscular dystrophy, hypotonia and dwarfism, mongolism, paroxysmal dyskinesia, myopathy, migraine, spastic paraplegia, multiple sclerosis, subacute combined degeneration and cranial polyneuropathy. Cerebellar signs have been reported in only two cases, and to our knowledge, this is the first case of cystinuria with cerebellar atrophy ever reported. Some common metabolic errors may have caused both disorders, although they also may have developed independently.

Cerebral CT scan abnormalities have been seen to be afflicted with some cases of classic occidental type congenital muscular dystrophy (CMD) with normal or borderline intelligence without neurological abnormality. A case is presented with early hypotonia, joint contractures, muscle biopsy features of CMD, normal intelligence and diffuse white matter hyperlucency on CT scan. Every CMD case should be screened with cerebral CT and magnetic resonance (MRI) scans to reach more aspects of this heterogenous disorder.

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.

Clinical features of a rare congenital myopathy, muscle-eye-brain (MEB) disease, are described in 19 patients. The pedigree data suggest an autosomal recessive inheritance. The patients presented with congenital hypotonia and muscle weakness. Serum CK was elevated, EMG was myopathic and muscle biopsy showed slight or moderate changes compatible with muscular dystrophy. Ophthalmological findings included severe visual failure and uncontrolled eye movements associated with severe myopia. The flash VEPs were exceptionally high, whereas non-corneal ERG was unrecordable. The EEG showed progressive abnormalities after the age of 6 months. Psychomotor development was slow during the first years of life, and mental retardation was severe. Most patients began to deteriorate around age 5 years. This change included spasticity and joint contractures. CT scans showed ventricular dilatations and abnormally low white matter density in several patients. Spasticity, high VEPs and ocular manifestations differentiate MEB from the Fukuyama type congenital muscular dystrophy.

Two patients with 'benign' congenital muscular dystrophy (CMD) have been observed for several years. Symptoms and signs of central nervous system (CNS) disease occurred at the age of 7 and 16 years, respectively. CNS involvement in CMD may be more common than generally recognized, slowly progressive and delayed in onset. The combination of congenital hypotonia, contractures, 'dystrophic' muscle biopsy changes and diffuse subcortical hypodensity on computed-tomographic scans seems unique and specific for CMD and of differential diagnostic significance.

We report the first Japanese female patient with Walker-Warburg syndrome. She had generalized muscle hypotonia with hydrocephalus due to Dandy-Walker malformation and bilateral microphthalmia with opaque corneas. She had severe motor and mental retardation. Muscle histology reflected advanced changes of muscular dystrophy. We discuss the relationship between Fukuyama congenital muscular dystrophy and Walker-Warburg syndrome, both of which fall within a spectrum of developmental abnormalities with a common cause. In Fukuyama congenital muscular dystrophy, ocular abnormalities are less severe.

A prospective study was done on 222 consecutive new patients referred to our pediatric muscle clinic to assess the diagnostic value of ultrasound imaging. Ultrasound scans were interpreted without knowledge of clinical presentation or results of other tests. Muscular dystrophy produced a brightly speckled pattern of increased echo from the muscle, whereas spinal muscular atrophy showed a moderate increase in muscle echo and associated muscle atrophy. Acute dermatomyositis produced a moderate increase in echo that varied markedly with the direction of the ultrasound beam in relation to the muscle fibres. The ultrasound scan was normal in children with hypotonia of cerebral origin, Prader Willi syndrome, ligamentous laxity, and other "nonneuromuscular" causes. In eight patients ultrasound scanning showed a striking degree of selective involvement of individual components of the quadriceps muscle, which provided considerable diagnostic help for selective needle biopsy. Ultrasound scanning in children has the major advantage of being a noninvasive and pleasant out-patient procedure, which can be readily done on multiple sites. It is a valuable screening test in the investigation of children with neuromuscular disorders.

Four cases of congenital muscular dystrophy are reported. Muscular weakness and hypotonia, with different clinical severity, was present from birth in three patients; in the fourth one, it began at two months old. Three cases had joint contractures. One patient died by respiratory infection. Serum CK level was very high in all of them. Muscle biopsies showed pathologic changes consistent with muscular dystrophy with endomysial and perimysial fibrosis and fatty infiltration. Authors analysed this illness emphasizing clinical and biochemical (CK) data so that an early diagnosis can be suspected.
