The 2 common carotid arteries bifurcate in the neck into the internal and external carotid arteries. The internal carotid artery enters the skull and further divides into the anterior and middle cerebral artery. During its short course in the neck, the carotid artery travels encased in the carotid sheath along with the vagus nerve and the internal jugular vein. During its course in the neck, the carotid artery is quite superficial, making it vulnerable to both penetrating and blunt traumatic injuries. We report here a case of a 40-year-old man who presented to the emergency department after sudden collapse and loss of consciousness a day after an attempted strangulation. Imaging revealed large hemorrhagic infarcts in the left anterior cerebral artery and middle cerebral artery territories as well as a smaller infarcts in the right anterior cerebral artery territory necessitating emergency decompressive hemicraniectomy. Our case report adds to the existing literature on nervous system injury due to strangulation. Physicians should be aware of the possibility of delayed presentation of neurological deficit after attempted strangulation. 相似文献

Among the reasons for the historic nature of the 2008 Democratic primary race was the attention paid to the “superdelegates”. The competitiveness of the primary and the important role the superdelegates played has led to calls for reform. This paper develops a formal model that explains why superdelegates selected one candidate over the other and why some superdelegates committed early in the primary season while others waited. Hypotheses are tested using an original dataset collected during the 2008 Democratic primary. The results suggest that although some superdelegates made their decision based on personal, idiosyncratic factors, for many superdelegates, Democratic voters played the most important role in their commitment process. 相似文献

Why do some countries have constitutional environmental rights while others do not? In this paper, I conduct statistical analyses to respond to this inquiry. Through studying the impact of intraregional constitutional design, I aim to understand why states adopt environmental rights. I argue that regional isomorphism—i.e., the tendency among states within a region to converge on certain policies—may explain the trend toward constitutionalization of environmental rights. In this paper I (1) define and provide historical background on environmental rights, (2) describe theories which support regional isomorphism as a means of explaining the adoption of constitutional environmental rights, and (3) conduct statistical tests to determine the validity of the regional isomorphism thesis. I find that the enactment of constitutional environmental rights within a region does not increase the likelihood that another state within the same region will include environmental rights within its constitution. 相似文献

Parity indicators in human skeletal material are highly desirable yet elusive. In this study, the relationships of dorsal pits and pubic tubercle elongation to parity are investigated in a sample of 148 modern female sets of pubic bones with associated birth information. The elongation of the pubic tubercle shows no significant correlation with number of births, but instead is associated with the distance this feature is from the pubic symphysis (p < 0.01) and the size of the arcuate angle (p < 0.05). Dorsal pits show a strong association with increasing numbers of births (p < 0.01), especially in younger women. However, in women over 50 years old, dorsal pitting is correlated with BMI (p < 0.05) and is not significantly correlated with number of births. While this study lends support to the correlation of dorsal pitting and parity, it currently does not reach the level of accuracy needed for forensic applications at the level of the individual. 相似文献
