Perforation of the uterus is one of the most serious complications associated with insertion of intrauterine contraceptive devices (IUD). According to recent studies, this lesion occurs in 0.87 per 1000 cases, but statistics generally fluctuate between 0.05 and 13 per 1000 insertions. "Primary" perforations occur at the time of IUD insertion, and "secondary," or delayed, perforations are usually assumed to be caused by reactive uterine contractions. We report an unusual case of uterine perforation, which occurred 9 days after the insertion of a Multiload-Cu 375 IUD. The criteria for differential diagnosis between primary and secondary complications are discussed, particularly from the perspective of medical malpractice cases.  相似文献

The Istituto Superiore di Sanità of Rome, Italy, in cooperation with Institut Municipal d'Investigaciò Mèdica of Barcelona, Spain, set up an external quality control program (HAIRVEQ) to evaluate reliability in hair testing for drug abuse by laboratories from the Italian National Health Service. Samples included in the program were real hair samples from drugs consumers. Prior to sending, hair samples were reduced to powdered form, mixed to ensure homogeneity and tested with GC/MS by four Reference Laboratories. Up to now, four different exercises have been concluded and 23 laboratories participated. Samples containing high and low concentrations of opiates, cocaine and metabolites, low concentrations of MDMA and two blank samples, were included in the intercomparison exercises performed in the first year of HAIRVEQ activities. Results show an insufficient performance of participating laboratories. About 82% of laboratories reported incorrect results on a qualitative basis (false positive and false negative results) for some of the submitted samples. More than one-half of laboratories reported quantitative results (60%). On the basis of the calculated z scores, only between 35 and 55% of results reported should be considered as satisfying. Guidelines have to be provided by Italian authorities for method validation as well as set of recommended cut-off concentrations to orientate laboratories in their quality objectives when developing analytical methodologies as tools to improve reliability and consequently performance of hair analysis.  相似文献

Microislands are not a hot spot of comparative government studies. Without good reasons. Surely, from a political perspective Microislands are not of great importance. But such an argument should not prevent researchers from taking a closer look at Microislands. Because they are perfectly designed to broaden our knowledge of the circumstances under which democracies occur and survive. In this paper three assumptions, taken from the rare literature on Microislands, are tested: territorial space, homogeneity and insularity. It can be shown that the geographical as well as the geopolitical position of Caribbean and south pacific microislands posses a high explanatory power for the question why those states are stable democracies.  相似文献

Research suggests that perceived appropriateness of parental discipline plays a role in whether adolescents accept or reject parental messages, but little is known about how adolescents conceptualize or construct their ideas of appropriateness. One hundred twenty-two adolescents (M age = 16.87) answered questions about past situations (both antisocial and prosocial), how parents responded to these situations, the adolescent's perceived appropriateness of the parent's reaction, how the parent's reaction made the adolescent feel, and what the adolescent thought the parent's intentions were. Appropriateness ratings were related to the type of parental discipline used, with yelling associated with lower ratings of appropriateness and talking associated with higher ratings. Ratings were also related to adolescents' emotions, with negative emotions associated with lower ratings of appropriateness and positive emotions associated with higher ratings. Lastly, ratings were related to adolescents' perceptions of parental intent, with inhibiting and controlling intentions associated with lower ratings of appropriateness and caring and helping intentions associated with higher ratings.  相似文献

This article examines the conceptual relationship between legal positivism and human rights, challenging the common idea that the two are in tension or that there exists, at most, a contingent relationship between them, whereby legal positivists can only recognize the normative validity of human rights if they happen to be inscribed in positive law. To do this, I focus on the thought and writings of one of the “founding fathers” of modern legal positivism: the Austrian legal theorist and political philosopher Hans Kelsen. In the first part, I show that Kelsen's conception of legal positivism is inextricably tied to — and, indeed, logically stems from — his moral relativism. In the second, I show that this form of relativism is also the philosophical foundation for Kelsen's commitment to democracy and human rights. Finally, in the third part, I examine the specific conception of human rights that results from this relativistic foundation, contrasting it with the “natural law” version that legal positivism excludes.  相似文献

Research on conflict-related sexual violence (CRSV) has grown rapidly over the last decade. This article consolidates existing social science research on CSRV according to two lines of inquiry: its causes and its consequences. Overall, research has considerably advanced our knowledge of the causes of CRSV, particularly in four aspects: purpose, context, individual motives and intra-group dynamics. However, there is a need to better understand the societal consequences of CRSV, in particular how it affects relations in families, and within and between communities. Overall there remains a shortage of empirical, in particular mixed-method, designs to produce research which is relevant for policymakers and practitioners.  相似文献
