The primary objective of revascularization procedures in the posterior circulation is the prevention of vertebrobasilar ischemic stroke. Specific anatomical and neurophysiologic characteristics such as posterior communicating artery size affect the susceptibility to ischemia. Current indications for revascularization include symptomatic vertebrobasilar ischemia refractory to medical therapy and ischemia caused by parent vessel occlusion as treatment for complex aneurysms. Treatment options include endovascular angioplasty and stenting, surgical endarterectomy, arterial reimplantation, extracranial-to-intracranial anastomosis, and indirect bypasses. Pretreatment studies including cerebral blood flow measurements with assessment of hemodynamic reserve can affect treatment decisions. Careful blood pressure regulation, neurophysiologic monitoring, and neuroprotective measures such as mild brain hypothermia can help minimize the risks of intervention. Microscope, microinstruments and intraoperative Doppler are routinely used. The superficial temporal artery, occipital artery, and external carotid artery can be used to augment blood flow to the superior cerebellar artery, posterior cerebral artery, posterior inferior cerebellar artery, or anterior inferior cerebellar artery. Interposition venous or arterial grafts can be used to increase length. Several published series report improvement or relief of symptoms in 60 to 100% of patients with a reduction of risk of future stroke and low complication rates. 相似文献

Parental alcoholism and early child development 总被引:2,自引:0,他引:2
In a cohort of 532 pregnant women from the general population, it was found by compilation of the results from interviews, police records, hospital records and social welfare records that 23 mothers and 51 fathers in 64 families (12%) were suffering from alcoholism/heavy drinking. In these 64 families, the mother was an addict in only 13 families, both parents were addicts in 10 families, and in the remaining 41 families only the father was an addict. Pregnancy, delivery, the newborn child and the child's development until their fourth year of life have been described using a multidisciplinary approach and a longitudinal prospective design. An hypothesis on mental and physical development, and the occurrence of psychopathological symptoms in the children was tested. None of the children of the 13 alcoholic mothers was born with foetal alcohol syndrome, but foetal hazard was indicated by lower birth weight and a higher rate of perinatal deaths. Children of alcoholic parents had retarded mental development and showed more behavioural problems until 4 years of age than controls, but the differences related to physical development during the first year of life had then disappeared. Boys were found to be more vulnerable than girls. The consequences of behaviour seemed to be more pronounced when both parents were alcoholics. No obvious deviation was found when only the father was addicted. Regarding mental development, it appears that factors related to parental alcoholism, including genetic and social factors, and the sex of the child, are of greater importance than the neonatal score on reduced optimality. 相似文献

This study investigated the impact of a home composing curriculum on kindergarten children's concepts about print (a measure of reading readiness), writing fluency (the number of words children can write), and writing achievement. In addition, the study investigated gender differences on the above measures, types of writing done by children at home, and family members with whom children wrote. The treatment group was found to be significantly higher on the Concepts about Print test, writing fluency, and the first post-test of writing achievement. There were no significant gender differences on any of the measures. Data from parent response sheets indicated that these children wrote notes, letters, and lists more than other types of writing. They wrote with their mother or alone more often than with other family members. The findings of this study suggest that a flexible home composing curriculum, combined with the sharing of writing at school can have an impact on reading readiness, the number of words children can write, and possibly writing ability. 相似文献

This introduction traces the increasing awareness of the prevalence of child sexual abuse over the last 20 years, examines the nature and consequences of such abuse and summarizes current information on the use of group treatment and its evaluation with sexually abused children and adolescents and their parents. Four examples of group treatment with different populations of abused children are described in this issue. 相似文献

Low‐income urban parents of color enrolled in a parent training study were interviewed to understand what motivated their participation and what led 30% of them to subsequently drop out. Most enrolled because they wanted to be better parents. Most dropped out because of time and schedule constraints. Retention was higher when parents' motivations for participation matched program goals. Program location and qualities of the recruiter were cited most often as important; financial compensation was cited least often as important. 相似文献

The psychiatric investigation of a sample of 101 epileptic patients (65 temporal lobe epileptics (TLE) and 36 non-TLE) through various methods of evaluation, showed that only a minority of TLE with DSM-III diagnoses of Organic Brain Syndromes had severe psychopathology and manifested some personality traits. Thus, these patients seem to be differentiated from the rest of epileptics, TLE and non-TLE, who had quite "benign" psychological problems, if at all. It is quite probable that this sub-group of TLE could be the main instigators and perpetrators of the "bad image" of epileptics. The findings are discussed in relation to the pertinent literature and some hypotheses are offered for their explanation. 相似文献

In his recent formulations of rational emotive therapy (RET), Ellis (1985) has increasingly emphasized what he believes to be the central role of necessitous thinking or musturbation in the development of depression. In his most recent article (Ellis, 1987), he suggests that necessitous thinking is the primary cognitive component of depression and that RET stands alone in its recognition of the role of this cognitive element. The present study addressed three issues raised by Ellis's paper: (1) Clarify whether necessitous thinking has been neglected by other cognitive theorists, (2) test empirically the role of necessitou thinking in depression relative to other established cognitive constructs, e.g., the cognitive triad (Beck, 1967), and (3) determine whether necessitous thinking is particularly salient in depression as compared with other forms of psychopathology. It was predicted that necessitous thinking would be found in other forms of psychology in addition to depression, and this was confirmed. The results are discussed as highlighting the importance of empirically testing theoretical predictions.From the Foundation for Cognitive Therapy. 相似文献

This is a critical review of 16 studies reporting a relationship between Crohn's disease and psychological variables. The studies reviewed indicate a relationship between the psychological variables of stressful life events, personality characteristics, and psychopathology and the onset and/or exacerbation of Crohn's symptoms. Personality characteristics such as depression, anxiety, and dependency are frequently reported as are the occurrence of stressful life events and the presence of psychopathology. The nature of the relationship is not explained by the research to date; however, the findings summarized in this report indicate that additional investigation into this association is warranted. A plan for such research is suggested. 相似文献

Personality,psychopathology, and nicotine response as mediators of the genetics of smoking 总被引:10,自引:0,他引:10
Individual differences in psychopathology, personality, and nicotine responsitivity and their biological bases are evaluated as mechanisms potentially mediating smoking heritability. Smokers are more likely to be high in neurotic traits (e.g., depression, anxiety, anger) and in social alienation (psychoticism, impulsivity, unsocialized sensation-seeking, low conscientiousness, low agreeableness) and low in achievement/socioeconomic status. Psychological and biological mechanisms putatively mediating these associations are reviewed. It is concluded that a number of relatively indirect and complex processes, as well as more direct (e.g., self-medication for psychopathology, nicotine sensitivity), mediate the inheritance of smoking behavior. 相似文献

An effective definition of psychopathology would be helpful in distinguishing between normal and abnormal behavior and would provide guidance for important public policy decisions. Overinclusive definitions, such as the capacity/disability formulation, do not provide meaningful direction for defining need or assessing eligibility for insurance or other entitlements. Coping failures due to lack of skill, inadequate preparation, or other factors should be distinguished from those due to dysfunction or disturbance of psychological mechanisms. The capacity/disability formulation encourages confusion between different performance decrements and gives no guidance for appropriate boundaries for psychotherapy. 相似文献
