对神经根型颈椎病CT扫描的价值探讨

对50例神经根型颈椎病的CT征象进行了分析,并与X线平片加以比较。认为CT不仅在神经根型颈椎病的诊断中具有独特作用,而且在确定手术方法和手术途径的选择上也很有意义。作者认为在CT机还没有普及的情况下,摄一张良好的钩椎关节放大斜位片或椎间孔断层片对诊断神经根型颈椎病应是首选的。CT和X线平片相结合,综合分析,更有价值。     

The Mitek mini anchor in the treatment of the gamekeeper's thumb

The fixation of a distally ruptured ulnar collateral ligament of the MP 1 (Metacarpophalangeal) joint without a portion of ligament which can be sutured or a small bony fragment can be accomplished with a variety of methods, most of which require drillholes through borth cortices and a counter incision as well as the removal of the material at a second stage [1, 11, 13, 15]. The Mitek bone mini anchor (Ethicon-Mitek®) proved to be a reliable and quick alternative [10, 12, 16, 18, 19]. It was successfully used in eleven patients with excellent stability of the reconstructed joint.     

The lumbar and lumbosacral facet-syndrome. Diagnostic measures,surgical treatment and results in 119 patients

Arthroscopic capsulorrhaphy formultidirectional instability

Multidirectional shoulder instability is a common affliction and is increasingly recognized as a debilitating condition in young, athletic patients. Most patients with this condition are in their third decade and have a history of macrotrauma or repetitive microtrauma. Complaints range from frank instability to instability with pain, or to pain alone. These patients may display clinical signs of instability, impingement, or both on physical examination. Generalized ligamentous laxity or shoulder laxity alone are usually present. A positive sulcus sign remains the most sensitive clinical test in distinguishing these patients, even though no data is available on the sensitivity or specificity of this examination. The greater majority of patients are successfully treated with an exercise program stressing rotator cuff and scapular stabilizer strengthening. When patients do not respond to conservative treatment, open capsular shift has been recommended to restore joint stability. Early successes with the arthroscopic treatment of anterior shoulder instability have led to the development of similar procedures for the treatment of multidirectional instability. This paper describes an arthroscopic, multiple suture capsulorrhaphy for the treatment of multidirectional shoulder instability, which is a modification of the procedure advocated by Caspari and reviews the 2-year results of the first 19 patients treated.     

Intraoperative radiotherapy of upper abdominal tumours

Thirty patients with malignant tumours in the upper abdomen underwent surgery and intraoperalive radiation (IORT), using electron beam, to: the surgical bed, residual or unresected tumour. The technical aspects and results of this treatment are described. Renal, adrenal, bile duct and gastrointestinal tumours were treated. along with several other lesions. The surgical procedure consisted in 10 cases simply of exposure of the tumour for IORT and in 20 the tumour was resected. The TORT dose ranged from 10 to: 20 Gv. In 13 patients, external beam radiation was also given to: residual tumour or to: areas of high risk for recurrence. Chemotherapy was given to: 10 patients. Tolerance to: the combined treatment was acceptable; with few complications related to: IORT.The median follow-up and survival time 23 months (range 4-more than 70 months). Local tumour control rate (or tumour stabilisation) is 90%. Distant metastases developed in 19 patients (63%). The actuarial survival rate for the group projected at 70 months (maximum follow-up) is 37%. IORT in useful in the management of tumours arising in the upper abdominal organs, for palliation surgery or when resectability of the tumour is in doubt. Indications for IORT include patients with uncommon tumours of the upper abdomen who are not be candidates for standardised cancer treatment.Presented at the European Congress of Radiology, Vienna, September 15–20,1991     

γ射线诱发人正常肝细胞基因组不稳定性研究

目的探讨电离辐射诱发的基因组不稳定性效应。方法采用^60Co γ射线照射人正常肝细胞，检测克隆形成率和微核发生率，利用单细胞凝胶电泳（SCGE）技术检测DNA损伤情况。照射2、4、6、8和10Gy后传代培养，在40代后各剂量组再次统一照射2Gy，进行辐射损伤的检测。结果首次照射后，克隆形成率随受照剂量的增大而降低。存活细胞经二次照射后，SCGE结果和微核发生率结果表明，首次照射剂量与子代二次照射后的损伤程度存在剂量效应关系。结论γ射线不仅在肝细胞中产生直接的生物效应，而且还可以诱发产生可遗传的基因组不稳定性，使子代细胞中的突变频率增加，表现出滞后的遗传改变。二次事件的放大作用是研究基因组不稳定性的一种较好方法。
