Paradoxical leadership in public sector organisations: Its role in fostering employee resilience

Government organisations, and their employees, need to be resilient to manage challenges such as resource constraints, rising demands, and the tensions and contradictions that underlie much public sector work, often stemming from the need to balance different stakeholder interests. Employee resilience, defined as the capacity to continuously adapt and flourish, even in the face of challenge, is an individual level construct that also benefits organisations. Despite its benefits, little is known about how to foster it. This paper explores whether paradoxical leadership (PL) can contribute to employee resilience. PL – the ability to balance competing structural and relational demands over time – may be one means of supporting employee resilience, as it corresponds to the tensions and paradoxes that exist in public sector work. This correspondence between PL and tensions in public administration work means that PL may also help employees behave resiliently. Findings from a quantitative survey (n = 233) in a large New Zealand public sector organisation indicate that PL antecedes resilience. The effect of PL facets on employee resilience is partially mediated by perceptions of organisational support.     

实验性兔羊水栓塞血浆NO和ET的含量变化

目的观察兔羊水栓塞(AFE)后血浆一氧化氮(NO)、内皮素(ET)含量的动态变化。方法采用怀孕家兔制作羊水栓塞动物模型,将不同性质的自身羊水注入兔血循环,分别在羊水注入前、注入后5min、45min从兔心脏取血,用镉还原法、放射免疫分析(RIA)法分别检测血浆中NO和ET的动态变化。结果注入羊水后ET含量显著增加,NO含量则显著降低,对照组无显著变化。NO与ET含量变化呈显著负相关。结论NO、ET的动态变化在羊水栓塞早期的一过性肺动脉高压及随后发生的DIC等过程中起重要作用。     

16例肺血栓栓塞猝死的法医学分析和临床研究

目的分析肺动脉血栓栓塞（pulmonary thromboembolism,PTE）猝死的法医病理学特点,探讨医疗过程中发生PTE的危险因素,为临床预防、治疗提供帮助。方法对本市2002年至2009年16例PTE猝死案件进行回顾性分析。结果每例均至少存在1项已知的高危因素,其中外伤12例,慢性疾病长期卧床1例,手术3例;发病到死亡的时间平均为1.2h,6例≤1h,3例≤12h。结论对于高龄（≥40岁）外伤或手术患者,预防、早期诊断和治疗PTE对于患者的生命至关重要,发现深静脉血栓形成者应采取紧急手段处理栓塞,谨防发生PTE致猝死。     

Amniotic fluid embolism-apropos two consecutive cases

Amniotic fluid embolism (AFE) is a sporadic, unpredictable, and usual fatal obstetric complication. The paper deals with two cases of maternal deaths because of AFE verified by medicolegal autopsy. In both the cases, several known risk factors associated with AFE, such as increased maternal age (41 and 35 years), diabetes, augmented labor, and cesarean delivery, were identified. Clinical features were typical, including sudden onset of cardiovascular and respiratory symptoms. In the patient who survived longer, both clinical and autopsy signs of disseminated intravascular coagulopathy were present, while they were absent in the case where death occurred rapidly. This paper describes briefly the particular features to look for at autopsy and stresses the importance of histology examination and staining techniques.     

Infant death due to air embolism from peripheral venous infusion

An otherwise healthy male infant was brought to the hospital because the mother suspected superficial infection at the operative site 5 days after an inguinal hernia repair. He was admitted to the pediatric unit overnight to be evaluated by his surgeon the next morning. When a venous infusion of maintenance fluids was started, the patient immediately went into cardio-respiratory arrest and was pronounced dead after resuscitation efforts failed. Subsequently, air collections were found in both venous and arterial circulations, including the splenoportal system. Detailed review of the clinical presentation and course, laboratory results, radiological, and pathological findings, along with a review of pertinent literature provides an explanation for the death by air embolism. Apparent inconsistent findings both radiographically and at autopsy are resolved. The mechanism of distribution of air to both systemic and splenoportal circulation is discussed. We believe this to be only the eighth case reported in English-language literature of infantile death from peripheral venous infusion. In all age groups, we find only six other cases in the English-language literature of gas found concomitantly in both the systemic and portal venous systems.     

Bear attack--A unique fatality in Finland

Fatalities due to animal bites, the vast majority of which are associated with dogs and big cats, are relatively uncommon and rarely described in the literature. Especially rare are fatal bear attacks on humans. We herein present a forensic investigation of a fatal assault, involving numerous bites on a 42-year-old man in Finland by an European brown bear (Ursus arctos arctos).     

浅析外伤性脑梗塞

通过十四例外伤后脑梗塞案例分析,对外伤与脑梗塞的关系进行阐述,认为外伤性脑梗塞的主要原因是脑动脉血栓形成和栓塞。动脉内膜损伤致血栓形成多在四小时后;颅内出血致血管痉挛造成脑血栓多在1至3周之间;外伤致动脉粥样硬化斑块脱落造成栓塞即刻发生,结合年龄大小、有无心血管疾患以及脑梗塞的部位,便可弄清损伤与脑梗塞的关系。     

APM染色法在羊水栓塞诊断中的应用价值

目的　探讨APM染色法在羊水栓塞 (AFE)病理学诊断中的应用价值。方法　采用APM染色法对 1988年至 2 0 0 1年确诊为AFE的 19例病例 (AFE组 )和羊水吸入性肺炎的胎儿 3例 (阳性对照组 )、其它死因的 10例产妇 (阴性对照组 )重新进行染色和组织学检查 ,对其检验结果进行比较分析。结果　阳性组全部检出羊水成分 ,阴性组部分病例检出羊水成分 ,发现漏诊、误诊各 1例。与HE染色相比较 ,APM染色能提高角化上皮和粘液的检出率。结论　APM染色能提高羊水成分的检出率 ,有助于提高AFE诊断的准确性 ,可用于AFE病理学诊断。

Fatal Fat Embolism After Penis Enlargement by Autologous Fat Transfer: A Case Report and Review of the Literature

Fat embolism is an incidental finding in cases of long bone fractures or other trauma, but it is also associated with liposuction and autologous fat transfer, a procedure where fat from liposuction is injected back into the same patient's face, breast, buttocks or penis. We here present a case of sudden death by fat embolism in a healthy young male, caused by a simple penis enlargement procedure, in which fat was injected into the penis shaft. We suggest that the risk of fat embolization might be higher when pretraumatized tissue is subjected to fat injection, like in this case, where a penis elongation was performed before the fat injection.
