Hepatic arterial embolization has been shown to be a safe and effective method for the palliation of symptoms in patients with metastatic disease, particularly those with secondary deposits from endocrine tumors. This review examines the indications for the procedure, discusses some aspects of technique, and assesses the potential benefits and complications of the method.
OBJECTIVE: A pattern of clinical, behavioral, and experimental findings suggests that individual differences in aggressive behavior may be related to immunologic processes. We evaluated two conflicting models of the relationship: 1) A positive association stems from an adaptive mechanism protecting aggressive individuals from increased exposure to immune stimuli and 2) a negative association is due to potential immunosuppressive effects of high testosterone levels. METHODS: We investigated the models using enumerative measures of cellular and humoral immunity in a sample of 4415 men aged 30 to 48 years who were interviewed and underwent a medical examination. RESULTS: Analysis revealed positive (and curvilinear) associations between aggressive behavior and enumerative measures of helper/inducer and suppressor/cytolytic T lymphocytes and B lymphocytes. The aggression-immunity relationship was independent of testosterone level, age, current health status, and negative health behaviors and was most pronounced for helper/inducer T cells. There was no evidence of a negative association between testosterone and any immune measure. CONCLUSIONS: In a large sample of men, individual differences in aggressive behavior were positively associated with enumerative measures of cellular immunity.
