Child death due to repeated episodes of physical assault or neglect has been termed the child abuse-maltreatment syndrome (CAMS). We characterized the injuries in a series of fatally abused or maltreated child to delineate objective diagnostic criteria for the CAMS for use by clinicians and pathologists. All deaths (age <17 years) investigated by the Office of the Chief Coroner for Ontario, Canada during the time period 1990-1995 were reviewed. Cases of CAMS were defined as death due to lethal recent injury or malnutrition in the presence of significant old (healing or healed) injuries indicative of repeated episode of inflicted trauma. The nature and frequency of the various injuries was determined. The frequency of the shaken baby syndrome, and the types and frequency of ano-genital injuries were also studied. Twenty-one cases of fatal CAMS were found in the study period. Most cases had significant recent head injury with intra-cranial hemorrhage (71%). Other significant recent injuries commonly observed included blunt injuries of the skin and soft tissues (67%), blunt abdominal trauma with visceral injuries (14%), and fractures (18%). Eight cases (38%) fulfilled accepted criteria for the shaken baby syndrome. Many children with fatal head injuries had evidence of older head trauma (38% of all cases). A significant minority of cases had evidence of malnutrition due to neglect (10%) or ongoing ano-genital injuries (10%). Most cases of child homicides due to repeated episodes of abuse or maltreatment involve head trauma including shaken baby syndrome. Fractures of long bone and ribs, the classical markers of child abuse, were relatively infrequent compared with head injury. A proportion of cases had ano-genital injuries due to repeated sexual abuse or punitive maltreatment. All clinicians and pathologists must recognize the wide spectrum of injuries in child abuse to ultimate protect the victim or other children in an at-risk situation.  相似文献

This paper traces the history of the current conflict between Israel and Palestine from 1948–2005 C.E. It focuses on the frontier conflict between Israel and Palestine, a conflict that has resulted in four major wars during the post-Second World War period, and that has left Israel as the occupying power over a large swathe of territory not allocated to it by the United Nations in 1947. It outlines the nature of the refugee problem in Palestine and neighboring Arab states, and defines the political problems posed both by relative Israel-Palestine population growth, and by the `right to return’ claim by ousted Palestinian Arabs. It reviews the political problems posed by religious extremism and theocratic government both in Israel and Palestine. It concludes with a brief discussion of the unpleasant alternatives left as the road map to peace disintegrates and outlines a preferred solution from the perspective of the advanced western nations.  相似文献

But actually, he thought as he re–adjusted the Ministry of Plenty's figures, it was not even forgery. It was merely the substitution of one piece of nonsense for another. Most of the material that you were dealing with had no connexion with anything in the real world, not even the kind of connexion that is contained in a direct lie. Statistics were just as much a fantasy in their original version as in their rectified version.  相似文献
