Lethal head ballistic trauma with a « nonlethal » projectile: A case report and review of the literature

Forensic investigations of cranioencephalic ballistic trauma involve several aspects, including the study of terminal ballistics. This includes the analysis of projectiles and the damage they cause. Although some projectiles are considered “non-lethal”, serious injuries and deaths secondary to the use of this type of ammunition have been reported. We report the case of a 37-year-old man who died from ballistic head trauma after the use of “Gomm Cogne” ammunition. A post-mortem computed tomography (CT) showed a right temporal bone defect and seven foreign bodies. Three of these were located in the encephalic parenchyma, which showed diffuse hemorrhagic changes. External examination indicated that this was a contact entry wound and confirmed encephalic involvement. This case illustrates the potential lethality of this type of ammunition with CT and autopsy with similar features to single projectile firearm injuries.     

Load distribution and postural changes in young adults when wearing a traditional backpack versus the BackTpack

Backpacks lead to poor posture due to the posterior placement of the load, which overtime may contribute to low back pain and musculoskeletal complications. This study examined postural and load distribution differences between a traditional backpack (BP) and a nontraditional backpack (BTP) in a young adult population. Using a 3D motion analysis system, 24 healthy young adults (22.5 ± 2.5 years, 12 male) completed both static stance and walking trials on a treadmill with No Load and with 15% and 25% of their body weight using the two different backpacks. There was a significant difference in trunk angle, head angle, and lower extremity joint mechanics between the backpack and load conditions during walking (p < .05). Notably, relative to the No Load condition, trunk angle decreased approximately 14° while head angle increased approximately 13° for the BP 25% state on average. In contrast, average trunk and head angle differences for the BTP 25% state were approximately 7.5° and 7°, respectively. There was also a significant difference in head angle from pre- to post-walk (p < .05) across backpacks, loads, and time. Taken together, the results indicate that the BTP more closely resembled the participants’ natural stance and gait patterns as determined by the No Load condition. The more upright posture supported by the BTP may help reduce characteristics of poor posture and, ideally, help to reduce low back pain while carrying loads.     

46例新生儿HIE振幅整合脑电图与脐动脉血气、Apgar评分、头颅MRI相关性研究

目的 探讨振幅整合脑电图能否作为早期诊断新生儿缺氧缺血性脑病(HIE)的依据.方法 选择新生儿HIE患儿46例为观察对象,分析aEEG异常程度与脐动脉血气pH值和BE值的相关性,同时分析其与Apgar评分及头颅MRI的相关性.结果 ①aEEG用于判断新生儿HIE的敏感性为70.8％,特异性为96.9％,说明aEEG的异常程度与HIE的分度存在有显著的相关性;②aEEG异常程度与脐动脉血气比较差异有统计学意义(P＜0.05);③aEEG异常程度与Apgar评分比较差异有统计学意义(P＜0.05);④aEEG异常程度与生后3～7d内的头颅MRI检查异常程度紧密相关.结论 新生儿HIE振幅整合脑电图异常程度与脐动脉血气pH值,Apgar评分及头颅MRI密切相关,可作为作为早期诊断新生儿HIE的依据之一.

An Experimental Model of Tumor Dormancy Therapy for Advanced Head and Neck Carcinoma

An experimental model of tumor dormancy therapy for advanced head and neck carcinoma was developed. After transplantation of KB cells into nude mice, the mice were given tiracoxib, a selective cyclooxygenase (COX)-2 inhibitor, probucol, an antioxidant, and S-1, an oral pro-drug of 5-fluorouracil (5-FU), or combinations of two of them. The combined administration of tiracoxib with probucol significantly inhibited the tumor growth. The angiogenesis in this group was markedly reduced. Tiracoxib and probucol did not affect the intratumoral concentration of 5-FU when coadministered with S-1. The combined use of tiracoxib and probucol is thus a candidate for use in maintenance therapy after the primary therapy for patients with advanced head and neck carcinoma.

护士长的人格特征、社会支持、婚姻质量与心理健康的相关分析

采用艾森克个性问卷（ＥＰＱ）、社会支持评定量表（ＳＳＲＳ）、ＯＬＳＯＮ婚姻质量问卷（ＥＮＲＩＣＨ）和症状自评量表（ＳＣＬ－９０）,对３５０名护士长作个性、社会支持、婚姻质量与心理健康的相关研究。结果显示：艾森克个性问卷中的神经质维度与心理健康呈高度负相关,护士长婚姻质量问卷中的过份理想化与其心理健康呈高度负相关。神经质倾向的人格特征和过份理想化的婚姻不利于护士长的心理健康。较稳定的情绪和对婚姻较为现实的认知有助于护士长的心理健康
