Cranial Trauma (cranial + trauma)
Selected AbstractsHealing Following Cranial Trauma,JOURNAL OF FORENSIC SCIENCES, Issue 2 2008Lenore T. Barbian Ph.D. Abstract:, This paper reports on the gross appearance of the initial osseous response following cranial gunshot wounds. A total of 127 adult crania and cranial sections were analyzed for four types of bone response: osteoblastic, osteoclastic, line of demarcation, and sequestration. In general, no osteoblastic or osteoclastic response was noted during the first week. This response was followed by an increasing prevalence of expression after this time. By the sixth week postfracture both osteoclastic and osteoblastic activity was scored for 100% of the sample. Further, our observations suggest that the line of demarcation may establish the boundary between the living bone and bone not surviving the fracture. Sequestration appears to be a long-term event and was scored as present well past the eighth week of healing. The osseous expression of infection following fracture was also considered.

Her skull was cleaved across the centre from side to side. The woman was buried with her head inside a ceramic pot, which is unusual for the site, but with jewellery similar to that in other burials. She was interred in a large cluster of graves, with a high proportion of infants and children. Her burial treatment suggests that she was not being treated punitively. The position of the mandible shows that the cleavage is not a postmortem artifact but it is not possible to determine the reason for it or whether it was the cause of her death or occurred immediately afterward. It is an unusual and intriguing enigma. Copyright © 2003 John Wiley & Sons, Ltd. [source] Ancient injury recidivism: an example from the Kerma period of ancient NubiaINTERNATIONAL JOURNAL OF OSTEOARCHAEOLOGY, Issue 2 2002Margaret Judd Abstract A topical trend in clinical research has been the study of repeat trauma, referred to by clinicians as "injury recidivism," which lends itself to the assessment of accumulated injuries among ancient people. The present investigation examined the healed injuries among two archaeological skeletal samples from the Kerma period (ca. 2500,1500 BC) of Sudanese Nubia. Both groups were known to have a high prevalence of multiple trauma,80% of 54 adults from the rural sites (O16 and P37) located near Dongola and 42% of 212 adults from the urban site of Kerma sustained nonfatal injuries. It was observed that a higher frequency of multi-injured adults displayed one or more violence-associated injury (cranial trauma, parry fracture). When all injuries were considered 38% of individuals with violence-related injuries had other traumatic lesions in contrast to 22% of individuals who experienced injuries associated with accidental falls (e.g., Colles', Smiths', Galeazzi, and paired forearm fractures), although this difference was not significant. When only the skulls and long bones were evaluated 81% of adults with multiple injuries to these major bones bore one or more violence-related injuries, while 60% of adults with single injuries sustained violence-related injuries. Most individuals with multiple injuries were male and less than 35 years of age; there was no significant difference in the frequency of violence- or accident-related multiple injury between the rural and urban communities. Although it cannot be established whether or not some of an individual's injuries were experienced during simultaneous or independent incidents, the pattern of multiple injury among these two ancient Nubian skeletal samples reflected the profile of injury recidivism observed by modern clinicians cross-culturally.

[source] Biocultural interpretations of trauma in two prehistoric Pacific Island populations from Papua New Guinea and the Solomon IslandsAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 4 2010Rachel M. Scott Abstract Two Pacific Island skeletal samples originating from the inland site of Nebira, Papua New Guinea (1230,1650) and a coastal site on the small island of Taumako, Solomon Islands (1530,1698) were examined for evidence of skeletal trauma using a biocultural approach. The types of trauma identified were cranial trauma, postcranial fractures, and piercing and sharp force trauma. Both samples exhibit trauma (Nebira, n = 9/28, 32.1%; Taumako, n = 17/133, 12.8%). Postcranial fractures are significantly higher in males from Nebira (Fisher Exact P value = 0.025). The prevalence of cranial trauma (n = 6/28, 21.4%) is significantly higher in Nebira individuals (Fisher Exact P value = 0.007). There is no conclusive evidence of piercing trauma at Nebira unlike Taumako, which has four individuals with evidence of piercing or sharp force trauma. Both samples show evidence of interpersonal violence and warfare. The results suggest the environment may have contributed to the pattern of trauma at these sites. These patterns are discussed within their cultural and environmental contexts. Am J Phys Anthropol 142:509,518, 2010. © 2010 Wiley-Liss, Inc. [source] Possible relationship of cranial traumatic injuries with violence in the south-east Iberian Peninsula from the Neolithic to the Bronze AgeAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 3 2009S.A. Jiménez-Brobeil Abstract The main aim of this study was to analyze the presence and distribution of cranial trauma, as possible evidence of violence, in remains from the Neolithic to Bronze Age from the SE Iberian Peninsula. The sample contains skulls, crania, and cranial vaults belonging to 410 prehistoric individuals. We also studied 267 crania from medieval and modern times for comparative purposes. All lesions in the prehistoric crania are healed and none of them can be attributed to a specific weapon. In all studied populations, injuries were more frequent in adults than in subadults and also in males than in females, denoting a sexual division in the risk of suffering accidents or intentional violence. According to the archeological record, the development of societies in the SE Iberian Peninsula during these periods must have entailed an increase in conflict. However, a high frequency of cranial traumatic injuries was observed in the Neolithic series, theoretically a less conflictive time, and the lowest frequency was in crania from the 3rd millennium B.C. (Copper Age), which is characterized by the archeologists as a period of increasing violence. The relatively large size and the high rate of injuries in Neolithic crania and the practice of cannibalism are strongly suggestive of episodes of interpersonal or intergroup conflict. The number and distribution of injuries in Bronze Age is consistent with the increase in violence at that time described by most archeologists. Am J Phys Anthropol, 2009. © 2009 Wiley-Liss, Inc. [source] Prehistoric trepanation in the Cuzco region of Peru: A view into an ancient Andean practiceAMERICAN JOURNAL OF PHYSICAL ANTHROPOLOGY, Issue 1 2008Valerie A. Andrushko Abstract In this study, patterns of prehistoric trepanation in the southern highlands of Peru were examined through an analysis of 11 Cuzco-region burial sites. Trepanations were found in 66 individuals, with several individuals exhibiting more than one trepanation, for a total of 109 perforations observed. The predominant methods used were circular cutting and scraping,methods that proved highly successful with an overall 83% survival rate and little ensuing infection. Survival rates showed a significant increase over time, apparently reflecting improvements in trepanation technique through experimentation and practical experience. Practitioners avoided certain areas of the cranium and employed methods that reduced the likelihood of damage to the cerebral meninges and venous sinuses. In many cases, trepanation as a medical treatment appears to have been prompted by cranial trauma, a finding that corroborates other studies pointing to cranial trauma as a primary motivation for the surgical procedure.

[source] Review of singleton fetal and neonatal deaths associated with cranial trauma and cephalic delivery during a national intrapartum-related confidential enquiryBJOG : AN INTERNATIONAL JOURNAL OF OBSTETRICS & GYNAECOLOGY, Issue 5 2005Fidelma O'Mahony Objective To review delivery details of intrapartum-related fetal and neonatal deaths with singleton cephalic presentation and birthweight of 2500 g or more in which traumatic cranial or cervical spine injury or substantial difficulty at delivery of the head was a dominant feature. Design Review of freestyle summary reports and standard questionnaire responses submitted to the national secretariat for the Confidential Enquiry into Stillbirths and Death in Infancy (CESDI) during the 1994/1995 intrapartum-related mortality enquiry following regional multidisciplinary panel review. Setting United Kingdom. Sample Of the 873 cases of intrapartum-related deaths reported in the 1994,1995 national enquiry, 709 weighed more than 2499 g. Reports from 181 (89 from 1994 and 92 from 1995) with a chance of meeting criteria for cranial or cervical trauma as significant contributors to death were examined in detail. Thirty-seven were judged to meet the criteria stated in the objectives (23 from 1994 and 14 from 1995) and form the basis for this review. Methods Electronic and hand search of CESDI records relating to intrapartum-related deaths. Main outcome measures Intrapartum events and features of care. Results There was evidence of fetal compromise present before birth in 33 of the 37 (89%) study group cases reviewed. One delivery was performed vaginally without instrumentation, and in one there was no attempt at vaginal delivery before caesarean section (CS) in the second stage of labour. Twenty-four cases (65%) were delivered vaginally and 11 (30%) by CS after failure to deliver vaginally with instruments. A single instrument was used in six cases of vaginal delivery (four ventouse and two Kjelland's forceps). At least two separate attempts with different instruments were made in 24 cases. Overall, the ventouse was used in 27 cases and forceps in 29 cases. In six cases, three separate attempts were made with at least two different instruments, all of which included use of ventouse. The grade of operator was recorded in 27 cases. Of these, a consultant obstetrician was present at only one delivery and no consultant was recorded to have made the first attempt to deliver a baby. In six cases, shoulder dystocia was also reported. Conclusions This study suggests a lower incidence of death from difficult cephalic delivery and cranial trauma than previously reported. The CESDI studies were believed to have achieved high levels of ascertainment for all intrapartum-related deaths from which the cases reported here were selected. Strictly applied entry criteria used in this study could have restricted the number of cases considered as could limited in vivo or postmortem investigations and lack of detailed autopsy. When cranial traumatic injury was observed, it was almost always associated with physical difficulty at delivery and the use of instruments. The use of ventouse as the primary or only instrument did not prevent this outcome. Some injuries occurred apparently without evidence of unreasonable force, but poorly judged persistence with attempts at vaginal delivery in the presence of failure to progress or signs of fetal compromise were the main contributory factor regardless of which instruments were used. [source] Diagnosis of perinatal stroke II: mechanisms and clinical phenotypesACTA PAEDIATRICA, Issue 11 2009P Govaert Abstract Introduction:, Here (and in an accompanying article dealing with definitions, differential diagnosis and registration), a structured sequential diagnostic flow is proposed to discern clinical phenotypes for perinatal stroke, including arterial ischaemic stroke (AIS), cerebral sinovenous thrombosis (CSVT) and haemorrhagic stroke. Material and results:, For neonatal AIS, the diagnostic sequence is infection, trauma, embolism, arteriopathy, other, primary thrombosis and unclassifiable; for neonatal CSVT, the sequence is infection, trauma, venopathy, other, primary thrombosis and unclassifiable. The proposed hierarchical diagnostic flows are an initial step towards a standard for registration of the causes of neonatal stroke. Such standardization should guide attempts at prevention and intervention. An extensive literature search and study of a retrospective cohort of 134 newborn infants with stroke suggest that embolism is the most common identifiable cause for stroke in general (25%), preceding trauma (10%) and infection (8%). Other causes, such as asphyxia, acute blood loss, extracorporeal membrane oxygenation, genetic disorders or prothrombotic conditions, are seen in <5% of cases. For neonatal AIS, the presence of an embolic phenotype is 33% in this cohort. The designation unclassifiable scored 34% for the entire stroke group and 25% for neonatal AIS. Complex arterial stroke with multiple arteries involved is often seen when the underlying cause is infection, cranial trauma or embolism. One important conclusion is that a means of prevention is avoidance of embolism from thrombosis outside the brain. Conclusion:, To prevent the occurrence and recurrence of neonatal ischaemic stroke, clinicians must develop a standardized diagnostic approach that results in characterization of the clinical phenotype.
