目的 探讨创伤性、迟发性颅内血肿的早期诊断和治疗的临床效果。方法 对22例病人的发病年龄、性别、伤因、早期诊断和治疗效果进行了回顾性分析。经过2—6个月，按GOS评定治疗效果。结果 良好者12例，中残者5例，重残者1例，植物生存者1例，死亡者3例，死亡率为14％。结论 早期诊断和治疗本病对于提高治愈率和降低死亡率至关重要，早期手术治疗本病，乃是多数病人首选的治疗方法。     

Periodontal mechano-sensory responses following trauma to permanent incisor teeth in children

Abstract –  The aim of this study was to investigate mechano-sensory responses of injured and uninjured incisor teeth. Twenty-five children who had experienced dental trauma, together with age- and gender-matched controls, were studied prospectively. Touch thresholds of incisor teeth from both groups were determined using calibrated sets of von Frey hairs (force range 0.5–10.0 g in 0.5 g increments) using a forced choice staircase method. Forces were applied perpendicular to the buccal enamel surfaces along the midline, 2 mm from the incisal edge. Touch threshold was defined as the lowest force detected in three out of the five occasions. Following statistical analysis, P  < 0.05 was considered significant. At initial examination, the touch threshold values of 25 traumatised teeth were significantly greater than the untraumatised controls ( P  < 0.001), and these values approached those of the control teeth over 3–12 months ( P  > 0.05). Dental trauma was associated with increased touch thresholds in permanent incisor teeth, with recovery toward healthy control values usually occurring between 3–12 months.

Granuloma annulare possibly triggered by antitetanus vaccination

We report the case of a 6-year-old girl with granuloma annulare (GA) possibly related to antitetanus vaccinations. The first episode occurred 2 months after the girl had been vaccinated but the lesions were not located at the vaccination site. After 1 year of being free of lesions, she had a second episode unrelated to vaccination. After another 6-month lesion-free period, the girl was administered another antitetanus vaccination and a solitary lesion developed at the vaccination site within 3 days. A few lesions developed on her legs in the 2 months following the appearance of the initial plaque. The literature includes two reports of cases with papular lesions limited to the hepatitis B vaccination site, both histopathologically consistent with necrobiotic granuloma, but clinically not suggestive of GA. To the best of our knowledge, GA following antitetanus vaccination and occurring at the vaccination site has not been reported before. Either the trauma alone from the injection or a vaccine-induced immunological reaction might have triggered the necrobiosis of collagen through some unexplained mechanisms.     

创伤后肝细胞凋亡与坏死的检测及其意义

目的 探讨严重创伤后肝细胞凋亡及坏死在急性肝功能障碍发病机制中的作用。方法复制多发性骨折合并休克的大鼠创伤模型,采用 Annexin－V－Flous、碘化丙锭(propidium iodid,PI)双标法经流式细胞仪检测创伤后各时间点肝细胞凋亡与坏死的数量变化,结合光镜、电镜和电泳观察细胞凋亡与坏死,并与肝功能变化相比较。结果创伤后早期肝细胞即发生凋亡和坏死,坏死肝细胞的数量进行性升高,与肝功能变化显著呈正相关;凋亡肝细胞在创伤后3h达高峰,部分凋亡肝细胞发生继发性坏死,其数量与肝功能变化显著正相关。结论肝细胞坏死与凋亡是严重创伤后肝功能损害的重要原因,坏死肝细胞是肝功能损害的直接因素,凋亡肝细胞通过发生继发性坏死加重肝功能损害。     

严重胸腹部闭合性联合伤致呼吸心跳停止成功救治1例

报告1例严重胸腹部闭合性联合伤所致的急性呼吸心跳骤停得到成功救治的病例。闭合性胸腹联合伤后,因病情可能发展,应随时注意复查胸片、血气等;若基层医院条件不够,应及时转往上级医院,以免延误患者的治疗。     

Fatal thromboembolic complications following assault in a subject with an abdominal aortic aneurysm

A 62-year-old male with no significant medical history developed thromboembolic complications in the lower limbs shortly after an assault which involved punching and kicking to the trunk. Laparotomy revealed intra-abdominal injuries and an abdominal aortic aneurysm. Death from multi-organ failure and sepsis occurred 9 days post-injury. The discussion concentrates on blunt force trauma to the abdominal aorta, specifically on causation, mechanisms of injury and complications.     

Specific selection of osteosynthetic material in the treatment of thoracic or lumbar spinal injuries by the posterior approach

Summary The authors report 165 cases of thoraco-lumbar lesions with neurological dysfunction. All the patient were operated. They analyze the neurological and mechanical results and indicate the use of different osteosynthesis apparatus according to the type and level of lesions.Harrington's rods seem to give more precise repositioning while Roy Camille's plates give more stability. When the posterior wall of the spinal canal is intact, Kempf's compression rods can be used.Thoraxic spine injuries seem to be an indication for Harrington's rods, while lumbar injuries seem to call for Camille's plates.
