Selective involvement of the quadriceps muscle in congenital muscular dystrophies: an ultrasonographic study.

Muscle ultrasound scanning is a non-invasive and painless technique for evaluating muscle disorders in childhood. We have performed ultrasound scans of the quadriceps muscle in 26 children with various forms of congenital muscular dystrophies. There were 8 patients clearly showing selective involvement within the components of the quadriceps. In all cases showing selective involvement, the rectus femoris was spared and the vastus muscles were the affected group. Our findings support the concept of heterogeneity, often encountered in congenital muscular dystrophies.

Hot water epilepsy.

The clinical and EEG features of 10 patients with hot water epilepsy were presented. Eight of the 10 cases were male. The mean age of onset was 4.7 years. In four patients partial and in six cases generalized seizures were seen. Three patients also had non-hot water precipitated seizures. Interictal EEGs showed generalized abnormalities in eight and focal abnormalities in two cases. CT was performed and found normal in two patients. Anticonvulsant therapy was instituted for all patients. In six cases with adequate follow-up, complete remission was obtained in four and the frequency of the seizures was decreased in two, with anticonvulsant therapy.

Intraventricular interferon and oral inosiplex in the treatment of subacute sclerosing panencephalitis.

We treated 22 patients with subacute sclerosing panencephalitis (SSPE) with intraventricular alpha-interferon (IFN) and inosiplex PO and followed them for 2 to 54 months. Three deaths occurred. Clinical improvement, demonstrated by decreasing scores on the Neurological Disability Index, occurred in 11/22 (50%); five patients became stable, and the progression rate of the disease decreased in three. The remission rate was significantly higher than untreated controls from the same institution. Patients who had a slowly progressive disease responded best to treatment. Serious side effects were rare. We recommend intraventricular IFN, combined with oral inosiplex, in the treatment of SSPE.

Occidental type cerebromuscular dystrophy: a report of eleven cases.

Occidental type cerebromuscular dystrophy (OCMD) forms a substantial distinct group within congenital muscular dystrophy (CMD). These patients invariably present with amyotrophy, multiple joint contractures, facial muscle involvement, normal or nearly normal intelligence, leukodystrophic appearance on CT scan, and dystrophic changes in muscle.

Tremor of tongue and dysarthria as the sole manifestation of Wilson's disease.

Neurological form of Wilson's disease in children usually manifests with dystonia as the initial sign. Tremor of extremities, dysarthria and ataxia may follow. Copper deposits in gray and white matter along with the basal ganglia. A pediatric case presenting with tremor of the tongue and dysarthria as the only findings of Wilson's disease is reported. Tongue tremor should also be taken into notice within the basal ganglia symptomatology.

Fukuyama type congenital muscular dystrophy in a Turkish child.

Congenital muscular dystrophy (CMD) is a heterogeneous group of disorders which is associated with more or less degrees of cerebral involvement. There are four separate entities within CMD nosology. Among these Fukuyama's CMD (FCMD) is highly prevalent in Japan, whereas the classic form with normal or subnormal intelligence, also known as the occidental type, covers the vast majority of cases in the West. We report a case of FCMD seen in a Turkish child.

N-acetylaspartic aciduria in Canavan disease: another proof in two infants.

Increased amounts of urinary N-acetyl-aspartic acid was found in two infants with biopsy proven Canavan disease. The aspartoacylase assay is a new tool for determining both the prenatal and antenatal diagnosis of Canavan disease. This assay should be screened in patients with early onset of psychomotor deterioration, macrocephaly, spasticity/hypotonia and white matter hyperleucency at CT scan.

Neurologic complications in chronic renal failure: a retrospective study.

We have retrospectively examined 324 patients with chronic renal failure and evaluated the probable underlying causes of neurologic complications, laboratory data and therapeutic interventions. The common neurologic problems in our patients were alterations in consciousness (40.7%) and convulsions (35.1%). When BUN concentration was above 135 mg/dl and creatinine clearance was below 8 m/min/1.73 m2, alteration of consciousness was observed and when BUN concentration was 200 mg/dl and creatinine clearance was below 7 m/min/1.73 m2, abnormal convulsives appeared. Changes in deep tendon reflexes and pathologic reflexes were associated with hypertension. All of the patients with cortical atrophy using computerized cranial tomography aluminum hydroxide at least for 18 months, and six of them had hemodialysis. Fourteen patients who underwent dialysis developed convulsions and were thought to have disequilibrium syndrome. These findings are consistent with the suggestion that the metabolic and biochemical derangements associated with CRF may be particularly detrimental to the still developing CNS of the child.

Cell mediated immunity in patients with subacute sclerosing panencephalitis.

Cell mediated immunity was assessed on the basis of total lymphocytes (TL), total T lymphocytes (TTL) counts, delayed skin test responses and in vitro leucocyte migration inhibition test (LIF) production in 25 patients with SSPE, classified according to the clinical stages of the disease. The patients in stage I of the disease did not show any defect in cellular immunity while the patients in stage II showed decreased TL and TTL counts, more negative skin test responses to PHA, SKSD and PPD, and unresponsiveness to SKSD of LIF production. When the patient group was evaluated as a whole, only the TL counts and the skin test responses against SKSD differed from those in the controls. These results suggest that the defects in cellular immunity demonstrated in the patients with SSPE may be due to SSPE or the measles virus itself rather than to a genetic factor predisposing patients to SSPE.

Cognitive and behavioural characteristics of children with idiopathic epilepsy in a low-income area of Ankara, Turkey.

Fifteen school-age children with idiopathic epilepsy but with no other neurological symptoms were compared with non-epileptic children, matched for age, on four cognitive tests selected to measure specific cognitive skills at two levels of functioning, and a behaviour rating scale. All children were from a low-income district of Ankara, Turkey. Epileptic children did as well as controls on the recognition of a geometric designs test but were significantly inferior at drawing these designs, suggesting some deficit at a cognitive level involving coordination of perception and motor activity. In language functioning, they were significantly poorer on the receptive test but not on the expressive test. They had significantly more behavioural problems than either the control group or their own siblings, those related to fears and anxiety being most prominent. However, in comparison with their siblings, they also had significantly more problems related to conduct- disobedience and inattention. These findings provide further evidence for the importance of some form of counselling for school-age epileptic children and their families.
