Dento-facial morphology and caries experience: an epidemiological study.

The aim of this study was to analyze the association between occurrence of enamel focal demineralization (EFD) lesions and caries on the smooth surfaces of permanent teeth and some parameters concerning dentofacial morphology in different age groups of Finnish children. Altogether 587 children aged 7, 9 and 12 years living in Helsinki and Kuopio, Finland were examined clinically and some parameters of dento-facial morphology were measured. Of the dento-facial morphological parameters, the size of the gonial angle seemed to be associated with caries indicators. The possible predictive value of dento-facial morphology for caries should be confirmed by longitudinal study.

EEG and CT findings in patients with panic disorder.

Fifty-four patients with panic disorder were investigated using extensive electroencephalographic (EEG) recordings and computerized tomography (CT). Fifteen (28%) of these patients had previously been treated for temporal lobe epilepsy or were considered to have another neurological disorder. EEG recordings showed increased slow-wave activity in 13 (24%) patients and CT scan revealed incidental abnormalities in 6 (20%) of the 30 patients investigated. Taking into account the limitations of the methods applied, the present results indicate that clear-cut epileptic EEG patterns only rarely occur in panic disorder: the vast majority of panic patients exhibit normal EEG and CT findings.

Ceroid lipofuscin in Hermansky-Pudlak syndrome and neuronal ceroid lipofuscinoses.

Ceroid lipofuscin has been found to accumulate in body tissues in two types of storage disease, the Hermansky-Pudlak syndrome (HPS) and neuronal ceroid lipofuscinoses (NCL), which exhibit different clinical patterns and also differ as regards the site of pigment accumulation. The storage material in both diseases is similar physically and biochemically.

Early clinical signs and prognosis in children with brain injuries.

The outcome of 76 brain-injured children treated at the Department of Neurosurgery, Kuopio University Central Hospital, Kuopio, Finland, during 1980-83 was analyzed to determine the prognostic value of early clinical signs and investigations. Five (8%) of the children died. The coma level (Glasgow Coma Score, GCS) was below 9 in 24 children, four (17%) of whom died. Three of these deaths occurred very early, during or soon after the computerized tomography (CT) study and in these cases aggressive treatment was withheld. There were actually no deaths in children with GCS of 6-8 and one death due to severe intra-abdominal injury in 52 children with GCS of 9-14. Seventeen (22%) of the children had multiple injuries. Fourteen children had significant intracranial hematoma or depressed skull fracture requiring surgical treatment, and all of these children did well. The intraventricular pressure was measured in 11 children with GCS of 3-5, all under controlled respiration. Six children had increased intracranial pressure (ICP), above 20 mmHg. In one child the pressure could not be managed, and she died. CT gave very important prognostic information. All children who died of early uncontrollable ICP already had marked hemorrhagic lesions in the basal cisterns, hypodense areas in the brain stem or brain stem compression. Early and repeated CT to show the complications and aggressive intensive care with intracranial pressure recording in children with GCS of 3-5 can keep the mortality associated with severe brain injury below 20% with an acceptable level of survival.

Multiple intracranial meningiomas associated with intracranial arterial aneurysm.

This report illustrates a patient who was found to harbor eight separate meningiomas associated with an intracranial arterial aneurysm. Five of the meningiomas were extirpated and the aneurysm was wrapped. The causality between multiple meningiomas and aneurysm is obscure. Although the introduction of CT has facilitated the diagnosis of multiple meningiomas there are however areas especially in the base of the skull and high parasagittally where small meningiomas may remain undetected.

Computed tomography findings in senile dementia and normal aging.

Computed tomography (CT) findings in 57 patients with senile dementia of Alzheimer type (SDAT), 19 patients with multi-infarct dementia and 85 controls of similar age and sex were studied. The SDAT patients differed from the controls of ventricular dilatation, frontal horn index, cella media index and the width of the third ventricle, and also in the index of cortical atrophy. Even the least severely demented SDAT patients differed from the controls. In the SDAT group with the increasing degree of intellectual impairment the ventricular dilatation increased, but cortical atrophy did not correlate with the psychological test score. The multi-infarct dementia patients differed from the controls in all CT variables including local changes. The SDAT patients had a more marked ventricular dilatation than the multi-infarct dementia patients. The multi-infarct dementia patients had more frequently local changes in SDAT patients. In the control group age correlated with ventricular dilatation, and the lower test scores correlated with cortical atrophy in the left temporal region.

EEG and computed tomography in the investigation of patients with senile dementia.

Fifty-six patients with senile dementia of Alzheimer type and 84 normal elderly people were examined by EEG and computed tomography. In discriminant function analysis of the computed tomography indexes the highest discriminant function coefficient was for width of the third ventricle. Using computed tomography, the groups were correctly classified for 84% of the subjects. In discriminant function analysis of the EEG variables the highest discriminant function coefficient was for dominant occipital rhythm; the groups were correctly classified for 86% of the subjects. In discriminant function analysis of the width of the third ventricle, an index of cortical atrophy, the dominant occipital rhythm, age and sex, the width of the third ventricle had the highest discriminant function coefficient; the groups were correctly classified for 90% of the subjects.

Spontaneous occlusion of the circle of Willis (moyamoya syndrome).

Three young autopsy and four temporal artery biopsy cases with an arteriographically typical moyamoya syndrome were studied by histologic, electron microscopic, and immunofluorescence methods. In all autopsy cases the intracranial segment of the internal carotid arteries showed concentric intimal thickening with severe stenosis or obstruction of the lumen, folding of the internal elastic lamina, and shrinkage of the external diameter of the vessel. Inflammatory infiltration was absent. Abnormal networks of thin-walled vessels, interpreted as secondary collaterals, were seen at the base and on the convexity of the brain. Degenerative changes, including a ruptured coronary aneurysm in one case, were also noted in the coronary and temporal arteries. In both the intra- and extracranial arteries repeated endothelial damage was indicated by the presence of redundant subendothelial basement membrane-like material. Lipid or calcium deposits were exceptional, and no evidence for the presence of immunoglobulins or components of the complement could be obtained by immunofluorescence. These pathologic alterations, distinct from atherosclerosis, fibromuscular dysplasia, and the established types of arteritis, seem to be identical in children and adults, in spite of different clinical manifestations of the moyamoya syndrome in these age groups. We suggest that a humoral factor, associated with infections, may induce repeated endothelial damage and intimal thickening in the intracranial arteries of genetically predisposed children in analogy with recent observations made in the coronary arteries of young subjects.

Moyamoya syndrome as a complication of radiation therapy. Case report.

A case is reported with occlusion and stenosis of the internal carotid arteries in association with basal telangiectasia. Fifteen years after postoperative irradiation for an optic glioma, radiological signs typical of the moyamoya syndrome were observed. Radiation therapy is discussed as the cause of the vascular damage in this case.
