Hemiparetic cerebral palsy: etiological risk factors and neuroimaging.

The purpose of this paper, which was conducted on 175 children with hemiparetic cerebral palsy (H-CP), was to verify the etiological risk period for this disease. Etiological risk factors (ERF) were detected through anamnesis: 23% in the prenatal period, 18% in the perinatal period and 59% of the patients the period was undefined (ERF in the prenatal and perinatal period was 41% and no ERF was 18% of the cases. The computerized tomographic scan (CT) and MRI were performed on all the patients, who were then classified according to their etiopathogenic data: CT1= normal (18%); CT 2= unilateral ventricular enlargement (25%); CT 3= cortical/ subcortical cavities (28%); CT4= hemispheric atrophy and other findings (14%); CT 5= malformations (15%). CT 5 was associated with physical malformations beyond the central nervous system and with prenatal ERF's, while CT 2 was associated with the perinatal ERF's, mainly in premature births. Magnetic resonance imaging was performed on 57 patients and demonstrated a good degree of concordance with the CT. Etiology remained undefined in only 37% of the cases after neuroimaging was related to ERF. A high perinatal RF frequency (59%) was observed and emphasized the need for special care during this period.

[Cerebrovascular disease in children: II. Clinical aspects in 42 cases].

We report the findings recorded in 42 children suffering cerebrovascular disease and assisted at the Hospital das Clínicas FCM-UNICAMP, over a 8 years period (January 1990 until April 1998). The ischemic type was the most common, and involvement of the middle cerebral artery, sudden onset of clinical manifestation with seizures and motor disability were more common in early aged children. Motor sequelae predominated in the follow-up of these children.

[Discitis in children. Study of 8 cases].

The authors report the study of eight children with discitis diagnosed through clinical, neurological and orthopedic evaluation. The evidence of self limiting inflammation or infection of the intervertebral disk space and of soft tissue were available by image studies. Findings with routine roentgenograms, computed tomography and magnetic resonance imaging are discussed.

[Neurologic semiology in a population of hearing impaired children].

A random sample of 42 sensorineural hearing impaired children (severe and bilateral) was studied, from special classes in Campinas, with chronological ages varying between 4 and 7 years old. The children of this sample were compared with two control groups of 42 children of the same chronological age, from regular classes of private and public schools. All of them were submitted to the traditional neurological examination. Hearing impaired children showed differences as to head circumference and muscle tonus. In the other examined items we found motor hyperactivity, cerebellar and ocular syndromes although there were no significant differences between the groups.

[Evaluation of the static equilibrium in a population of hearing impaired children].

A random sample was organized with 42 children with congenital sensorineural auditory deficit (severe and bilateral) from special education schools in Campinas. Chronological ages ranged from 4 to 7 years of age. This sample was compared with two control groups of 42 children of the same chronological age but attending normal classes. All were submitted to 9 tests of the set of static equilibrium of the Evolutive Neurologic Examination. It was observed that in the position of equilibrium with opened eyes (test 8) there were no differences between the groups. In the Romberg position, the hearing impaired children of 4, 5 and 6 years of age showed a significant decrease in the ability to do the test (test 9); those of 7 years of age had equal ability whether of the control or the deficient groups. Hearing impaired children were less able to do other static equilibrium tests (heel-toe or one foot or tip-toe standing tests, with opened or closed eyes: tests 10, 12, 16, 20, 24, 25 and 26). The use of detailed neurological semiology allowed us to support the alteration of the static equilibrium in this group of hearing impaired children.

[Congenital hemiparesis: complementary neuropsychological evaluation with computer].

We present the neuropsychological assessment with computer aid of six cerebral palsy children. Three children had right hemiparesis and three, left hemiparesis. The tomographic examination showed parietal cavities (porencephalic cyst in 4 children, ischemic injury in 1 case and subarachnoid cyst in 1 case). We have proposed to assess the visuo-spatial function since we suspected the children could have disturbance of this function. We did not detect this disturbance. On the other hand, the children had astereognosia and the right hemiparetic children preferred to execute signs on the right part of the computer visor. We discuss and propose explanations for both findings.

[Infratentorial malignant neurinoma: report of a case].

A solitary malignant schwannoma of the foramen jugular, unassociated with von Recklinghausen's disease in a two years and nine months old girl is presented. A partial removal of the tumor was carried out. The low incidence in this age group is emphasized in report to the literature reviewed.
