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.     

后纵隔巨大甲状腺乳头状癌一例

患者女,48岁。两年前无明显诱因出现轻微进食梗噎感,抬头时加重,未予治疗。近半年,梗噎感加重,并出现胸闷、咳嗽,痰中带血,遂来我院就诊。胸部CT显示:左后纵隔食管后方见一长条形低密度影,密度不均,其上方见环形斑     

Counterfactual (‘if only’) thinking in women with chronic widespread pain

The study explored the counterfactual thinking that women with chronic and widespread pain showed in response to what they themselves considered to be particularly stressful situations. Counterfactual thinking in 125 women sick‐listed due to chronic and widespread pain was investigated in terms of structure, function and control focus. The women were asked, for each of three types of problems that they indicated in a questionnaire to affect them most strongly, to describe a typical occurrence of it and to complete a counterfactual sentence in connection with it of the type ‘If only . . .’. The majority of counterfactuals pertained to predominantly somatic problems (e.g. musculo‐skeletal problems, pain and fatigue) classified as being affective rather than preparative and self‐focused rather than external, whereas in counterfactuals relating to predominantly psychological/psychosocial problems a preparative function and an external focus were more prominent. The numbers of problems listed and the numbers of situations responded to counterfactually were positively correlated. The counterfactuals, although often related to somatic problems, generally concerned psychological or psychosocial matters such as finances and paid or unpaid work. A contextual approach to elucidating counterfactual thinking based on subjects' own experiences is seen as providing valuable insight into what bothers them most.

多层螺旋CT扫描图像数据对经蝶窦入路穿刺三叉神经节及其分支的可行性研究

目的 探讨经蝶窦入路穿刺三叉神经节及其分支的可行性,分析两者的毗邻关系及相关限制因素.方法 对110例成年中国人头部薄层CT轴位原始资料进行多平面重组,观察圆孔、卵圆孔、翼腭窝（管）、Meckel腔与蝶窦外侧壁的关系,测量蝶窦外侧壁至诸结构的骨壁厚度.结果 ①圆孔紧靠蝶窦外侧壁的前外下方,骨壁厚度＜2 mm者84例（76%）;②重组图像可显示翼腭管全程,翼腭窝与蝶窦前下外侧壁之间的骨壁厚度＜2 mm者77例（70%）;③卵圆孔距离蝶窦外侧壁距离＞5 mm 98例（89%）;④由蝶窦腔内经颈内动脉管前方入路,斜向后下外方可及Meckel腔,骨壁厚度1～5 mm,颈动脉管为重要骨性标志.结论 经蝶窦内可分别穿刺或开放圆孔、翼腭窝和Meckel腔,而经蝶窦内穿刺卵圆孔基本不可行;经蝶窦入路至三叉神经节及其分支的可及性与蝶窦气腔的位置和扩展程度有关.     

应用上唇外侧组织瓣旋转修复下唇缺损

目的:探求上唇外侧组织瓣在修复较大面积下唇缺损中的作用。方法:根据患者下唇缺损情况,设计上唇外侧组织瓣,旋转后插入缺损组织,同时在缺损吻合处,将上层外侧旋转瓣内侧粘膜肌肉向外牵拉形成部分新的红唇,然后逐层相对缝合,修复缺损。结果:自2003年1月应用此方法修复患者6例,术后随访1～2年,唇部外形好,无流涎,无口闭合不全,效果满意。     

Lower limb blocks for children

Femoral and lateral cutaneous nerve of the thigh blocks have been performed in a group of 50 children; the method has not previously been described in paediatric practice. The technique was judged to have been successful in 48 (96%) of the children. There were no early or late complications. It is concluded that these blocks are easy to perform, even in small children and infants, and that they can produce reliable postoperative analgesia for a variety of orthopaedic and plastic procedures.     

Spinal Drop Metastasis from a Posterior Fossa Choroid Plexus Papilloma

Choroid plexus papillomas (CPPs) are typically considered as benign tumors, with a favorable long-term prognosis. Drop metastasis of CPP into the spinal subarachnoid space is rare. We report a 42-year-old woman who presented with headache and back pain 6 years after removal of a posterior fossa CPP. Magnetic resonance imaging revealed mass lesions in the lumbosacral subarachnoid space and recurrent intracranial tumor. The lesions were resected and histologically diagnosed was CPP. We consider that CPP can spread via cerebrospinal fluid pathways and cause spinal drop metastasis. Therefore, it is necessary to evaluate the whole spinal axis and to perform periodic follow-up examinations in patients with CPP.     

腮腺手术中耳大神经后支保留的临床意义

目的 探讨腮腺手术中耳大神经后支保留的可行性、方法及临床价值。方法 我们对48例腮腺肿瘤患者，按常规隐蔽切口腮腺手术方法进行治疗，保留或不保留耳大神经后支。分别于术后10d及1、6、12个月进行随访，检测耳廓上部、耳垂、耳下区、耳前区和耳后区的触觉、痛觉，并观察其感觉变化情况。结果 48例中35例耳大神经后支保留，耳廓上部及耳后区感觉无减退。术后早期耳前、耳垂及耳下区感觉有不同程度的减退，以耳前区最明显，随着时间延长症状逐步好转，6个月时感觉接近正常。另13例耳大神经切断患者感觉减退症状更加明显，恢复时间延长。结论 腮腺手术中耳大神经后支保留是可行的，所采用的方法可靠，可减轻局部麻木感，提高患者术后早期生活质量，降低神经切断后产生局部永久性麻木的可能性。
