The underlying mechanism of cervical soft tissue emphysema (CSTE) in hanging remains unclear. The aim of this study was to determine the frequency of CSTE in cases of hanging. The sample included 83 deceased persons, average age 55.3 ± 17.9 years. CSTE was established in 44 cases. CSTE is presented as frothy air, soap bubble-like formations in superficial and/or deep connective tissue between the neck muscles up to the ligature mark, visible during gross neck examination, using special neck autopsy technique-preparation of the neck organs in layers. The interpretation of positive CSTE must be taken with caution: it could be an antemortem phenomenon possibly because of either Macklin Effect or direct or indirect trauma to the cervical airways, as well as an ante- or postmortem artifact. 相似文献

In the Czech lands (included in Czechoslovakia until the end of 1992), rock music has evolved through three phases. In the first phase, lasting until 1968, rock musicians had no ambition to offer social or political commentaries. This began as the era of rock ‘n’ roll, which is to say music being performed for dancing. The second phase began after the Soviet bloc invasion of Czechoslovakia in August 1968, lasting until the end of the communist era in 1989. In this phase, rock musicians (no longer playing rock ‘n’ roll were closely monitored by the authorities and were expected to sing happy songs, submitting their song texts to the authorities for approval in advance of performing them. In spite of this control, some rock groups purposefully sang political texts in the 1970s and 1980s, mocking or criticizing the communists, albeit often cryptically. Finally, in the third phase – since 1989 – having lost their ideological foe, Czech rock groups have for the most part become politically disengaged. 相似文献
