The purpose of this study is to show the spectrum of adjacent organ invasion and to make a brief review of hepatic alveolar hydatid disease (AHD), using CT and MR imaging. We retrospectively reviewed CT and MR images of three patients with various adjacent organ invasions surgically and histologically proven to be AHD. Local invasion to right kidney and adrenal, right hemidiaphragm and lung were detected in one patient, right adrenal in another patient and gall bladder, duodenum, gastric wall and pancreas invasion in the other. AHD may rarely extend to the gall bladder, stomach, duodenum, pancreas, right adrenal and kidney, diaphragm, pleura and lung. The extension of the disease outside the liver is usually encountered in patients with large, peripherally located masses in the advanced stage of the disease. 相似文献

In a series of 11 melancholic patients who received both right unilateral and bilateral ECT during a single course of treatment, mean and minimum postictal heart rates were greater after bilateral ECT. Greater catecholamine release during bilateral ECT is the most likely explanation for these effects. These differences complement other evidence that bilateral ECT has a more pronounced physiological impact than unilateral ECT. 相似文献

Global and regional cerebral blood flow (CBF) were evaluated with single photon emission computerized tomography (SPECT) utilizing both 133Xenon (133Xe) (47 subjects, 47–82 years old) and 99Tc-hexamethylpropyleneamine oxime (99Tc-HMPAO) (27 subjects, 47–80 years old). The 133Xe results showed: among total subjects, no age-related decline in global CBF, but a significant regional decline in the occipital lobe (p < 0.05); among men, significant age-related declines in global, frontal, temporal, occipital and right hemisphere CBF (all p < 0.05); among women, no age-related decline in global or regional CBF. The 99Tc-HMPAO results showed no age-related decline in either global or regional perfusion among total subjects, men or women. These results suggest that age-related global and regional (including frontal lobe) CBF declines do not occur in healthy control subjects after the age of 45 years. However, gender differences in age-related CBF changes warrant further study. 相似文献

This study uses data from the Epidemiologic Catchment Area (ECA) surveys to examine the strength of the association between psychotic symptoms and violent behaviour, controlling for underlying mental disorder, substance abuse, sociodemographic characteristics and use of mental health services, in a representative sample of community residents. A replication is conducted of a study that found an increased risk of violence associated with a particular cluster of psychotic symptoms involving perceived threat and internal control-override (TCO). Respondents who reported TCO symptoms were about twice as likely to engage in assaultive behaviour as those with hallucinations or other psychotic symptoms, and about five times as likely as those with no mental disorder. The combination of substance use disorders with TCO symptoms added significantly to the risk of violent behaviour. Those with a history of using mental health services also posed a higher risk of violence, probably due to the differential selection of more severely ill and ‘dangerous’ individuals into treatment settings.
