A twenty-three years old woman, without previous heart disease developed endocarditis with negative bloods cultures on the fourth month of her third pregnancy. Fever was controlled through antibiotics, however she developed cardiac insufficiency and was submitted to surgery for replacement of aortic valve with a bioprosthesis. The post operative period showed no problems and the patient was discharged on the forty second day after admission. On the thirty ninth week of pregnancy she gave cesarean birth, without complications. The newly born, apgar 5 (1 min.) and 7 (5 min) presented signs of neurological problems, characterized on the second month as a cerebral atrophy. Among various possible factors, the most likely would be cardiopulmonary bypass circulation as the cause of the neurological malformation.

Congenital and acquired cerebrovascular diseases in the very young age group are reviewed and discussed. Whilst saccular aneurysms are rare arteriovenous malformations and cavernous hemangiomas represent the most frequent types of all congenital anomalies. The aneurysm of the great vein of Galen manifests in the newborn period and mostly is mistaken for congenital heart disease. If the infant survives this angioma causes hydrocephalus. A particular type of phakomatosis combines intracerebral pure venous malformation with homolateral port-wine nevus on the front, often causing epileptic seizures. Spontaneous intracerebral hemorrhage occurs in children with small cavernous hemangiomas. Acquired arterial lesions may develop during fetal life by embolism, causing porencephaly or unilateral brain atrophy. The "Moyamoya" syndrome represents a frequent multi-arterial lesion causing characteristic ischemic episodes. Etiology is still obscure. We do not even know if the disease is acquired or congenital.

The cranial computerized axial tomography (CAT) findings in groups of patients with epilepsy, migraine, hypertension, and other general medical disorders have been reviewed to assess the frequency and patterns of focal and diffuse brain damage. In addition to demonstrating focal lesions in a proportion of patients with seizures and in patients presenting with a stroke, the CAT scan showed a premature degree of cerebral atrophy in an appreciable proportion of patients with long-standing epilepsy, hypertension and diabetes, and in some patients with migraine, valvular and ischaemic, heart disease, chronic obstructive airways disease, and chronic renal failure. The value of CAT as a means of screening for brain damage in groups of individuals at risk is discussed.

Over 60 entries in the genetic catalog have cardiomyopathy features--32 autosomal dominant, 35 autosomal recessive and X-linked. Over 40 present in, or can have survival into, adult life. Major clinicopathologic categories of these cardiomyopathic disorders included: sudden death (13 entities); cardiac conduction disturbance important feature; associated myopathy or motor dysfunction; storage diseases with cardiac involvement; cardiac amyloidoses; and, other categories. Genes, abnormality of which can cause hypertrophic cardiomyopathy (HCM), have been identified on chromosomes 1, 14 and 15, the locus on chromosome 14 involving the B-myosin heavy chain gene, but at least one unidentified locus is known to exist and there is a suggestive locus on chromosome 16, so that HCM is not a single disease but a group of disorders with clinicopatholopic similarities. To investigate these aspects of HCM in some detail, sixty-six patients with "sharply demarcated" differential myocardial fiber bundle hypertrophy (DMBH), considered to be of significant degree, from a pediatric autopsy data base of approximately 8,000 cases, were reviewed. Twenty-three of the patients died suddenly, without antecedent significant cardiac dysfunction, seven had clinical congestive heart failure of varying duration, three were stillborn, six showed evidence of aspiration of amniotic sac content (three had history of fetal distress), five had ischemic bowel disease, three (two with clinical cerebral palsy and one with Ondine's curse syndrome) had cerebral atrophy and sclerosis and one had extensive more acute encephalomalacia, and a variety of other major "causes of death" were present. Whether all infants and children with DMBH meeting the criteria used, who do not have congenital heart disease, have dominant hypertrophic cardiomyopathy (HCM) cannot be established by studies of this type, but the "concentration" of a gene or genes for HCM in pediatric autopsy series because the strong effect of HCM on life expectancy is relevant to this possibility. The data raise the question that stillbirth, fetal distress with aspiration of amniotic sac content, ischemic bowel disease and cerebral atrophy and sclerosis may be hitherto underappreciated features of HCM in childhood, and that patients with HCM may be peculiarly liable to die with certain types of septic shock, such as acute meningococcemia. In the material of this study, sudden death was statistically more frequent in females than in males in childhood (p < .029).

The objective of this retrospective study was to determine the incidence and types of cranial ultrasound abnormalities in full-term infants with congenital heart disease (CHD). We reviewed the cranial ultrasound scans of 49 full-term infants with CHD and compared them to 42 healthy full-term control infants. The relationship of each abnormality with the type of CHD, the presence of cyanosis, and cardiac catheterization and cardiac surgery were examined. We found that infants with CHD had a higher incidence of cranial ultrasound abnormalities than control infants (59% versus 14%; p < 0.001). Cerebral atrophy and linear echodensities in the basal ganglia and thalamus were the most common sonographic findings in infants with CHD, particularly in those with coarctation of the aorta or ventricular septal defect. Intraventricular hemorrhage occurred more often in infants with acryanotic CHD than in those with cyanotic CHD. Cardiac catheterization and cardiac surgery had no significant effects on cranial ultrasound findings. We conclude that cranial ultrasound abnormalities are very frequent in full-term infants with CHD. These findings emphasize the importance of cranial ultrasonography and long-term neurodevelopmental follow-up of infants with CHD.

It is concluded that the most important determinants for cerebral neurodegenerative changes and cognitive decline during aging are neuronal shrinkage and/or loss, which are accelerated by certain risk factors: e.g. TIAs, hypertension, heart disease, hyperlipidemia, smoking, heavy alcohol consumption, male gender, low educational status, family history of cerebrovascular disease and absence of estrogen replacement therapy among women. Some of these risk factors are remediable by therapeutic interventions, including prevention of TIAs and medications that control hypertension, heart disease, hyperlipidemia and estrogen replacement in postmenopausal women, as well as abstention from abuse of tobacco and alcohol. Cerebral neurodegenerative changes measured by neuroimaging appear to be premorbid markers for depleted neuronal and synaptic reserves which predispose to the onset of dementias of both VAD and DAT types. Normal subjects at risk for cognitive decline include those with TIAs, hypertension and heart disease since these risk factors measurably accelerate cerebral atrophy, ventricular enlargement, leukoaraiosis, and decline in cortical perfusion.

Factors accelerating cerebral degenerative changes represent potentially modifiable risks for cognitive decline. Putative risks accelerating subtle cognitive decline and dementia were correlated with repeated measures of cerebral atrophy, CT densitometry, perfusions, and cognitive testing among 224 neurologically and cognitively normative aging volunteers. After age 60, cerebral atrophy, ventricular enlargement, polioaraiosis, and leukoaraiosis geometrically increased as perfusions declined. Risks accelerating perfusional decline, cerebral atrophy, polioaraiosis, and leukoaraiosis were: transient ischemic attacks (TIAs), hypertension, smoking, hyperlipidemia, male gender. At age 71.5 +/- 11.9, subtle cognitive decline began, accelerated by TIAs, hypertension, and heart disease. Leukoaraiosis began before cognitive decline. TIAs, hypertension, and hyperlipidemia correlated with vascular dementias. Excessive cortical perfusional decreases and cerebral atrophy correlated with cognitive decline. Family history of neurodegenerative disease correlated with Alzheimer's disease. We concluded that TIAs, hypertension, hyperlipidemia, smoking, and male gender accelerate cerebral degenerative changes, cognitive decline, and dementia.

Putative risk factors accelerating mild cognitive decline and dementia were correlated with repeated measures of cerebral atrophy, CT, densitometry, perfusions, and cognitive testing among neurologically and cognitively normative aging volunteers. A total of 224 normative subjects at increased risk for cognitive decline were admitted to the study. Mean entry age was 59.5 +/- 15.8 years. Mean follow-up is 5.8 +/- 3.3 years. At follow-up, 22 developed mild cognitive impairment (41 CCSE >/= -3), 19 became demented-8 with Vascular type (VAD), 11 with Alzheimer's type (DAT)-and 183 remain cognitively unchanged. Cerebral atrophy, tissue densities, and perfusions were measured by Xe-CT. After age 60, cerebral atrophy, ventricular enlargement, and polio- and leuko-araiosis geometrically increased as perfusions declined. Risk factors accelerating perfusional decline, cerebral atrophy, polio-araiosis, and leuko-araiosis were: transient ischemic attacks (TIAs), hypertension, smoking, hyperlipidemia, and male gender. At age 71.5 +/- 11.9, mild cognitive impairment began accelerated by TIAs, hypertension and heart disease. Leuko-araiosis began before cognitive decline. TIAs, hypertension, and hyperlipidemia correlated with VAD. Excessive cortical perfusional decrease, gray and white matter hypodensities, and cerebral atrophy correlate with cognitive decline.

We investigated the influence of brain atrophy and white matter lesions on cognitive function in elderly people. We selected 33 subjects (mean age, 79.2 +/- 5.1yrs) with a MMSE score from 14 to 30 who had no previous history of stroke from the outpatients in the Memory Clinic of our hospital. These subjects were divided into four groups on the basis of their MMSE score as follows: 14-20; moderate dementia (Moderate-D, n = 9), 21-23; mild dementia (Mild-D, n = 9), 24-27; mild cognitive impairment (MCI, n = 10), 28-30; normal (Normal, n = 5). Among these four groups, we compared the frequency of the associated risk factors for cerebral infarction (hypertension, diabetes mellitus, hyperlipidemia, heart disease), and the severity of brain atrophy and cerebral white matter lesion which were visually evaluated by MRI technique. Brain atrophy and white matter lesions were assessed by reviewing the cerebral cortex and hippocampus, and deep white matter lesion (DWML) and periventricular hyperintensity (PVH), respectively. Brain atrophy was divided into three grades (mild, moderate, severe) and white matter lesions were classified into four grades (0-3) using Fazekas's criteria. We performed statistical analysis to detect t parameters which correlate with and influence MMSE scores from among the MRI findings. The cases with dementia were all diagnosed as Alzheimer's disease. There were no significant differences among the four groups in mean age, the incidence of individual associated risk factors, the severity of cortical atrophy, or the grade of DWML (< or = 2) and PVH (< or = 2). However, the frequency of hippocampal atrophic change greater than a moderate grade increased in parallel with the exacerbation of reduced cognitive function (Normal; 20%, MCI: 40%, Mild-D; 56%, Moderate-D 89%), and approximately 76% with such a change were AD cases. Statistical analysis showed a significant negative correlation between the grade of hippocampal atrophy and MMSE score (r = -0.518, p < 0.005) and a great influence of hippocampal atrophy on that score (step-wise regression analysis: r = 0.518, p < 0.005). From the above results, it was suggested that more than moderate atrophic change in the hippocampus might possibly be related with cognitive impairment and that both DWML and PVH less than the second grade had little influence on the decline of brain function.

The Marshall-Smith syndrome (MSS) is rare congenital disorder, characterized by a triad of orofacial dysmorphism, failure to thrive, and accelerated osseous maturation. An 8-year-old boy with MSS associated with congenital glaucoma, corneal erosion, laryngomalacia, glossoptosis, choanal stenoses, bilateral peripheral hearing defect, ventriculomegaly, congenital heart disease (atrial septal defect), chronic pulmonary disease, and scoliosis was reported. A tracheostomy with endotracheal tube insertion was performed for his difficult airway. He has longer survival time than those MSS patients hitherto reported. High-resolution chromosome banding and extensive metabolic investigation did not detect any abnormality, except for low blood levels of zinc and thyroxine. Besides, brain atrophy with hypoplastic cerebellum and brainstem, and bilateral hydronephrosis with hydroureter were detected by image studies.
