Pediatric intracranial aneurysms——clinical characteristics and therapeutic strategies

Objective To assess the radiological characteristics and therapeutic strategies of intracranial aneurysms in children. Methods From our dedicated neurovascular databank of patients, we reviewed 23 consecutive children who had 24 intracranial aneurysms. There were 14 boys and 9 girls with a mean age of 9.09 years ( range 1 - 14 years ). Results Intracranial aneurysms in children ≤ 14 years constituted 1.3% of all intracranial aneurysms. Internal Carotid artery (ICA) and middle cerebral artery (MCA) were the most frequent sites for aneurysms. About 58.3% of the aneurysms were complex, including dissecting, pseudoaneurysm, giant and fusiform aneurysm. 1/3 of all aneurysms were located in posterior circulation. Only 1 case had multiple aneurysms in this case series. Almost half of all cases presented with subarachnoid hemorrhage and others presented with mass effect. 14 cases underwent endovascular treatment. 4 patients received microsurgical therapy. 5 cases did not receive microsurgical or endovascular therapy, 2 of them whose aneurysms spontaneously thrombosed during follow up. One boy with left vertebral artery giant aneurysm died after endovascular therapy owing to gradual thrombosis in basilar artery. Another child had poor outcome because of rerupture of aneurysm before operation. Whereas the majority had a favorable outcome. Conclusions Intracranial aneurysms in children had many clinical and radiological characteristics different from those in adults : ( 1 ) remarkable male predominance; ( 2 ) ICA and MCA were the most common sites for aneurysms; (3) high incidence of large, traumatic, infectious, dissecting and fusiform aneurysms. (4)For pediatric intracranial aneurysms, both microsurgical approaches and endovascular treatment were effective. Endovaacular therapy was the best choice for complex aneurysms.

健康教育在儿童口腔保健中应用的初步探讨

在推进儿童口腔保健健康教育过程中，我院自2001年10月运作至今，采取各种形式，使广大家长重视孩子口腔卫生。提高对口腔疾患的预防保健意识，纠正了孩子的一些不良口腔习惯，顺应了高质量的生活方式。现将健康教育在儿童口腔卫生保健工作中开展的必要性及有关形式介绍如下。     

腺苷与异丙酚预处理对犬心肌缺血再灌注损伤的保护作用

目的探讨腺苷与异丙酚预处理对犬心肌缺血再灌注损伤的保护作用。方法 21只杂种犬,雌雄不拘,随机分为3组(n=7):缺血再灌注组(A组)、异丙酚预处理组(B组)、异丙酚与腺苷联合预处理组(C组)。A组冠状动脉的左前降支结扎60min后松开结扎,再灌注:120min;B组缺血前30min经静脉以5．6mg·kg-1·h-1速率持续泵注异丙酚30min;C组缺血前10min经主动脉根部一次性注入腺苷(10mmol·L-1,10ml),其余处理同B组。记录心脏血液动力学指标,并行节段性室壁运动评分(RWMS)。结果缺血即刻出现了缺血性心电图的变化。与基础值比较,A组缺血期及再灌注期 LVEDP升高,CO、SV、LVEF、CPP、RPP降低,再灌注期MAP降低,HR减慢,B、C组上述缺血再灌注诱导的血液动力学变化减弱,A组缺血期及再灌注期RWMS增加,但B、C组缺血期RWMS低于A组(P< 0．05或0．01)。结论异丙酚预处理对犬心肌缺血再灌注损伤有一定的保护作用,腺苷预处理并未增强其保护作用。     

抗抑郁疗法可改善大脑活性

两项初步研究发现,被确诊为严重抑郁症的患者当其疾病对抗抑郁药物治疗或心理治疗有反应时,会出现许多相同的大脑改变。如果这两项研究结果在将来的工作中能得到进一步的证实,那么抗击严重抑郁症的忧郁、情感淡漠和绝望症状的各种不同的药物治疗和交谈疗法将集中在共同的大脑区。这两项新的研究报告发表在近期出版的《普通精神病学文献》杂志上。     

脸色腰段椎间盘突出症21例临床分析

胸腰段椎间盘突出症罕见,约占椎间盘突出的0.6％～4％。随着CT及MRI的应用,其发病率有增加的趋势。因其发病率低,报道较少。但由于病变位于脊髓圆椎段,其发病较下腰段椎间盘突出有很大的特殊性,故有必要结合我院近年收治的21例对其作一回顾性分析。1 临床资料
