An evaluation of community antenatal care.

A study to ascertain how the community based antenatal services in the East End of Glasgow related to the guidelines set by a Working Party on Ante-Natal and Intrapartum Care (Royal College of Obstetricians and Gynaecologists, 1982) is reported. All community based clinics were visited and described. The socio-economic status of the sample population was defined and users' views and preferences sought. The women sampled were often socially and economically disadvantaged. Unemployment was high. They received their community antenatal care from midwives, general practitioners and consultants in both health centres and general practitioner surgeries. Women were generally satisfied with the care they received. Answers to more specific questions indicated, however, that more information and individualised care would be appreciated.

[Anti-inflammatory, analgesic and antipyretic effect of various plant extracts and their combinations in an animal model].

Antiinflammatory, Analgesic and Antipyretic Effects of Various Plant Extracts and a Combination Thereof in Animal Models. The three main components comprising the efficacy of non-steroidal antiinflammatory drugs could be demonstrated for STW 1 in different animal models. The phytotherapeutic preparation, containing three individual plant extracts (Populus tremula, Solidago virgaurea, Fraxinus excelsior) produced dose-dependent antiinflammatory, analgesic and antipyretic effects which were similar to those of the reference substances salicyl alcohol and indometacin. As each of the individual extracts displayed considerable efficacy, it may be assumed that each of them contributes to the overall effects of the combination STW 1.

Neuropsychological characteristics of subjects with and without neocortical Alz-50 immunoreactivity.

We performed quantitative histopathology and Alz-50 staining on 8 non-demented and 16 demented subjects who had received yearly neuropsychological evaluations as part of prospective studies of dementia. Of the 8 non-demented subjects, four had begun to show signs of cognitive decline on serial neuropsychological testing. These subjects showed marked decline on the Fuld Object Memory Evaluation, a test of recent memory. Scores on IQ tests and the Blessed test of orientation, memory, and concentration showed fluctuations but not consistent declines. These old-old, retired subjects were called "cognitively impaired" but not demented because they did not show decline in activities of daily living or social interactions. Five of the non-demented subjects had numerous cortical senile plaques and met standard pathological criteria for Alzheimer's disease (AD), but only one of the five was Alz-50 positive. That subject had shown the most consistent decline on neuropsychological scores. Ten of 11 clinically demented subjects with pathological evidence of AD were Alz-50 positive. All five clinically demented subjects with non-Alzheimer dementias on pathological examination were Alz-50 negative. Alz-50 may stain plaques found in AD, but not stain plaques which accompany aging. The cognitive impairment found in the Alz-50 negative subjects may be age-associated and not indicate early AD.

Pediatric acquired immunodeficiency syndrome. Neurologic syndromes.

Central nervous system (CNS) dysfunction was documented in 61 of 68 infants and children with symptomatic human immunodeficiency virus infection. The most frequent manifestations included acquired microcephaly, cognitive deficits, and bilateral pyramidal tract signs. Lymphoma of the CNS, cerebrovascular accidents, and CNS infection caused by conventional pathogens were documented in only ten children (15%). Neurologic deterioration in 11 children was subacute but steadily progressive; in 31 the course was more indolent and began with a plateau. Of these 31 children, 13 had further neurologic deterioration and the conditions of three improved. Seventeen children had a static course with cognitive deficits (seven children) or cognitive plus neurologic impairment (ten children). Neuroradiologic studies in the children with a subacute progressive or plateau course disclosed cerebral atrophy, white matter abnormalities, and calcification of the basal ganglia. Postmortem findings included variable degrees of inflammatory response, multinucleated cells, calcific vasculopathy, and pyramidal tract degeneration. Computed tomographic studies of the children with a static course were normal or showed mild atrophy, but poor brain growth was documented by serial head circumference measurements.

Clinico-pathologic studies in dementia: nondemented subjects with pathologically confirmed Alzheimer's disease.

We compared neuropsychological findings in 28 longitudinally evaluated elderly subjects with their postmortem neuropathology, including senile plaque and neurofibrillary tangle counts from standardized sections. Nine of the subjects were not demented when evaluated just prior to their death. Numerous cortical senile plaques and other changes of Alzheimer's disease (AD) occurred in six of nine nondemented old-old subjects. Five of these six subjects had shown decline on yearly neuropsychological tests but their cognitive impairment was too mild to meet clinical criteria for dementia. Whereas cortical senile plaque count did not distinguish well between demented and nondemented subjects, every subject with numerous cortical neurofibrillary tangles was demented. The nondemented subjects with Alzheimer pathology may have had "preclinical" AD, or numerous cortical plaques may occur in some elderly subjects who would never develop clinical dementia.
