回顾性分析颅内肿瘤患者术后感染危险因素

目的:了解神经外科颅内肿瘤切除患者术后相关感染（HAI）的发生情况及其危险因素，为制定干预措施提供理论依据。方法:收集 2017 年1月至2018年12月1 049例颅脑手术患者的临床资料，根据术后是否发生颅内感染将患者分为感染组 91例和非感染组958例。对两组患者进行临床资料的单因素和多因素logistic回归分析。结果:颅内肿瘤患者术后医院感染率为8.67%。两组在年龄、性别、职业、文化程度、民族、药物过敏、切口等级等方面比较差异无统计学意义（P＞0.05），麻醉方式、手术等级、转科情况、住院天数和住院费用两方面比较差异有统计学意义（P＜0.05）；经过logistic多因素回归分析显示麻醉方式、住院天数是颅内肿瘤手术患者术后医院感染的独立危险因素，其OR及95％CI分别为5.173（2.738～9.774）、1.132（1.079～1.189）。结论:颅脑手术患者中HAI发生率较高，应根据危险因素采取有效预防和控制措施，以降低HAI的发生率。     

Biodegradable versus titanium osteosynthesis in maxillofacial traumatology: a systematic review with meta-analysis and trial sequential analysis

Titanium osteosynthesis is currently the fixation system of choice in maxillofacial traumatology. Biodegradable osteosynthesis systems have the ability to degrade in the human body. The aim of this study was to conduct a systematic review, with meta- and trial sequential analyses, to assess the efficacy and morbidity of biodegradable versus titanium osteosynthesis after maxillofacial trauma. MEDLINE, Embase, and CENTRAL were searched for randomized controlled trials and prospective and retrospective controlled studies. Five time periods were studied: perioperative, short-term (0–4 weeks), intermediate (6–12 weeks), long-term (>12 weeks), and overall follow-up. After screening 3542 records, 24 were included. All had a high risk of performance and detection bias due to the nature of the interventions. Meta-analysis showed no differences in efficacy or morbidity between biodegradable and titanium osteosynthesis. The risk of perioperative screw breakage was significantly higher (risk ratio 17.13, 95% confidence interval 2.19–34.18) and the symptomatic plate removal rate lower in the biodegradable group (risk ratio 0.11, 95% confidence interval 0.02–0.57), which was confirmed by the trial sequential analysis. The quality of evidence ranged from very low to moderate. Based on the narrative review and meta-analyses, current evidence shows that biodegradable osteosynthesis is a viable alternative to titanium osteosynthesis when applied in the treatment of maxillofacial trauma, with similar efficacy but significantly lower symptomatic plate removal rates. Perioperative screw breakage occurred significantly more often in the biodegradable group compared to the titanium group.     

The functional and structural changes in the basilar artery due to overpressure blast injury

Overpressure blast-wave induced brain injury (OBI) leads to progressive pathophysiologic changes resulting in a reduction in brain blood flow, blood brain barrier breakdown, edema, and cerebral ischemia. The aim of this study was to evaluate cerebral vascular function after single and repeated OBI. Male Sprague-Dawley rats were divided into three groups: Control (Naive), single OBI (30 psi peak pressure, 1 to 2 msec duration), and repeated (days 1, 4, and 7) OBI (r-OBI). Rats were killed 24 hours after injury and the basilar artery was isolated, cannulated, and pressurized (90 cm H₂O). Vascular responses to potassium chloride (KCl) (30 to 100 mmol/L), endothelin-1 (10⁻¹² to 10⁻⁷ mol/L), acetylcholine (ACh) (10⁻¹⁰ to 10⁻⁴ mol/L) and diethylamine-NONO-ate (DEA-NONO-ate) (10⁻¹⁰ to 10⁻⁴ mol/L) were evaluated. The OBI resulted in an increase in the contractile responses to endothelin and a decrease in the relaxant responses to ACh in both single and r-OBI groups. However, impaired DEA-NONO-ate-induced vasodilation and increased wall thickness to lumen ratio were observed only in the r-OBI group. The endothelin-1 type A (ET_A) receptor and endothelial nitric oxide synthase (eNOS) immunoreactivity were significantly enhanced by OBI. These findings indicate that both single and r-OBI impairs cerebral vascular endothelium-dependent dilation, potentially a consequence of endothelial dysfunction and/or vascular remodelling in basilar arteries after OBI.     

微创穿刺抽吸术与开颅手术治疗脑出血的疗效

目的探讨微创穿刺抽吸术与开颅手术治疗脑出血的疗效。方法选择2017年1月-2018年1月治疗的脑出血患者80例作为对象,根据住院时间先后顺序随机数字表分为对照组(n=40)和观察组(n=40)。观察组给予患者微创穿刺抽吸术治疗,对照组给予患者开颅手术治疗,比较两组患者术后总治愈效率和手术开展时间、住院天数。结果观察组手术开展时间、住院天数短于对照组(P<0.05);观察组的总治愈效率为90%高于对照组75%(P<0.05);观察组患者术后意识恢复时间短于对照组(P<0.05)观察组患者术后肢体障碍及肺部感染、伤口感染发生率均略低于对照组,但差异不具有统计学意义(P>0.05)。结论微创穿刺抽吸术在脑出血临床治疗中比开颅手术总治愈率高、安全性高、恢复快。     

An art therapy intervention for symptoms of post-traumatic stress,depression and anxiety among Syrian refugee children

This study first examined the prevalence of psychological symptoms among Syrian refugee children (N = 64) and assessed the effect of an art therapy intervention on post-traumatic stress, depression and anxiety symptoms. The Stressful Life Events (SLE) Questionnaire was used to measure stressful and traumatic experiences. The main outcome measures were UCLA Post-Traumatic Stress Disorder Parent version, Child Depression Inventory and State-Trait Anxiety Scale. After the baseline assessment, a five-day art therapy intervention, which is based on Skills for Psychological Recovery, was implemented. Findings of the study indicated that 60.3% (N = 35) of Syrian children who participated had high risk to develop post-traumatic stress disorder (PTSD) according to the SLE scale. The 23.4% of the children had PTSD symptoms while the 17.6% showed severe depression symptoms. Moreover, the 14.4% of the children showed severe levels of state anxiety symptoms and the 31.1% showed severe levels of trait anxiety symptoms. Findings of the study indicated that trauma, depression and trait anxiety symptoms of children were significantly reduced at the post-assessment. However, for state anxiety scores, significant differences between pre- and post-assessments did not appear. Therefore, it could be said that art therapy may be an effective method to reduce post-traumatic stress disorder, depression and trait anxiety symptoms among refugee children.

??Objective    To investigate the characteristics of indirect injury of periodontal membrane caused by maxillofacial impact injury. Methods    The study was carried out at the laboratory of oral and maxillofacial trauma in Fourth Military Medical University??from November 2013 to January 2014. Totally 18 dogs were divided equally into six groups with random allocation??the right mandible of each dog was impacted by a cylindroid iron cap whose weight was 0.26kg??but teeth were not injured directly??the animals were killed 6 h??24 h??3 d??7 d??2 wk and 4 wk later??respectively??the histopathologic manifestations of periodontal membrane of the fourth premolar of right mandible??the second premolar of right mandible and the second premolar of left mandible were observed. Results    The injury of periodontal membrane of the fourth premolar of right mandible was relatively obvious??but the pathologic changes were reversible??periodontal membrane of the second premolar of right mandible was injured slightly??yet no obvious histopathologic change could be observed in periodontal membrane of the second premolar of left mandible. Conclusion    Maxillofacial impact injury can cause indirect injuries of periodontal membrane of adjacent teeth??but the pathologic changes are reversible??traumatic severity decreases as the distance of the tooth to the wound area increases.
