扩大的椎板间开窗治疗腰椎间盘突出伴侧隐窝狭窄（附140例报告）

本组采用的扩大的椎板开窗术治疗腰椎间盘突出合并侧隐窝狭窄140例。结果全部优良，与适应症严格选择和手术损伤小有关。强调切除卡压神经根的侧隐窝后壁外侧，即上关节突的冠状面．不失其脊椎三柱系统的三角结构。俯卧位头低足高，可减少硬膜囊张力避免负损伤。切除棘突下椎板时，用神经拉勾代替神经剥离器易于分离黄韧带，用90度的椎板咬骨钳斜向棘突方向，可满意地切除该部份椎板黄韧带，并可刮切椎板内层。神经根周围滴入醋酸炎舒松A2-3ml，术后疼痛锐减。减压窗口置盖明胶海绵有其争议，作者实践体会放置害处不大，要求病人有“护腰”意识。     

Heat probe thermocoagulation as a substitute for surgical intervention to arrest massive peptic ulcer hemorrhage: an experience in 153 cases

In a period of 2 years 7 months, we performed heat probe (HP) thermocoagulation in 153 cases of massive peptic ulcer hemorrhage. The male/female sex ratio was 125/28. The average age was 57.6 +/- 1.3 years (mean +/- SEM; range, 17 to 88). There were 69 cases (45.1%) of spurting hemorrhage, 50 cases (32.7%) of oozing hemorrhage, and 34 cases (22.2%) of nonbleeding visible vessels. Seventy-seven patients (50.3%) were in shock before therapy. After therapy we obtained initial success in 147 cases (96.1%). Rebleeding episodes occurred in 23 patients (15.6%) within 1 month after therapy. Nineteen patients received a second therapy, and treatment in 15 of these cases (78.9%) was ultimately successful. Finally, treatment in 142 cases (92.8%) was ultimately successful. The duration of hospitalization was 6.3 +/- 0.4 days (mean +/- SEM). After discharge all patients were followed at the outpatient department for at least 1 month. Sixty-seven patients were followed endoscopically for at least 2 to 3 months after therapy. Fifty-six patients (83.6%) had a healed scar at the previous bleeding site 2 months after therapy, and 62 patients (92.5%) had a healed scar 3 months after therapy. We conclude that HP thermocoagulation is an ideal and reliable modality of therapeutic endoscopy in arrest of massive peptic ulcer hemorrhage. HP thermocoagulation may become the first choice of therapy for massive peptic ulcer bleeding in the near future.

眼球挫伤与锌

从１９９１年１１月到１９９２年８月对５０例眼挫伤的血清锌进行测定，３６例异常占７２％，其中有眼底改变占７５％。视神经视网膜挫伤锌值增高。低锌影响杆细胞及锥细胞代谢致视力低下，低锌影响视色素合成及色素上皮代谢，造成伤后视网膜色紊乱。     

石刻雕塑作业劳动卫生学调查及实验研究

测定了石雕作业粉尘浓度，几何平均浓度为８２．３５～３．６７ｍｇ／ｍ３。工人职业性健康检查结果，接尘工人的咽部充血、咳嗽、咯痰检出率高于对照组；肺功能低下的检出率也高于对照组。该厂自１９７２年以来发生尘肺患者１７例，其病情发展和晋期缓慢，发病工龄长。动物实验研究表明，石雕粉尘有轻微的致纤维化作用。     

Oral and dental manifestations in diabetic and nondiabetic uremic patients receiving hemodialysis.

OBJECTIVE: The aim of this study was to examine the dental condition and oral manifestations in diabetic and nondiabetic uremic patients undergoing hemodialysis. STUDY DESIGN: A total of 128 patients undergoing hemodialysis therapy were classified into the diabetic and nondiabetic groups and examined for uremic oral manifestations, dental caries, and the periodontal status. All the patients received predialytic salivary pH examination. In the diabetic group, the correlation between oral findings and glycemic controlled levels, which was collected based on Hb A1C values, were further studied. RESULTS: The diabetic group exhibited significantly higher prevalence of caries and more severe dry mouth, taste change, and mucosa pain than the nondiabetic group. The diabetic group tended to have lower predialytic salivary pH, and patients with poor glycemic control (ie, Hb A1C > 9%) showed higher incidence of dry mouth, mucosal pain, and tongue coating. However, the DMFT and CPI index were not associated with glycemic control in the diabetic group. CONCLUSIONS: This study reveals that diabetic uremic patients undergoing maintained hemodialysis exhibited a potentially higher risk for dental decay and xerostomia. Lower salivary pH and poor glycemic control may affect oral manifestations. Further research is needed to clarify the combined influence of diabetic nephropathy on oral health.

Management of congenital tracheal stenosis

Objectives: Congenital tracheal stenosis is a rare disease. Various methods for treatment exist but there is still much debate as to the appropriate surgical procedure. We present our surgical experiences of patch tracheoplasty and slide tracheoplasty as viable methods for the treatment of congenital tracheal stenosis. Methods: From 1994 to 2002, 13 patients were diagnosed with congenital tracheal stenosis. Eight patients (7 symptomatic and 1 asymptomatic) had their stenosis corrected, three by means of pericardial patch tracheoplasty, four by slide tracheoplasty, and one by resection and anastomosis. Concomitant operations were performed on six patients to treat congenital cardiovascular disease. Five patients showing no significant symptoms did not undergo tracheal surgery and received only cardiac procedures. A retrospective review of the hospital course, complications, and long-term results was conducted. Results: Among the patch tracheoplasty group, every patient suffered from granulation tissue formation. One patient died of respiratory acidosis and one was hospitalized due to recurrent granulation tissue, which required frequent bronchoscopy. The third patient from this group is free of all symptoms. Among the slide tracheoplasty group, one patient died of anastomosis disruption. The three remaining patients are alive and well. The one patient who received resection and anastomosis is alive without symptoms. Conclusions: Surgical repair of long-segment congenital tracheal stenosis exhibited high mortality and morbidity rates. Every patient that underwent pericardial patch tracheoplasty suffered from troublesome granulation tissue. As slide tracheoplasty provided relatively good results in the short and mid-term follow-up periods, it seems to be a preferred method for the treatment of long-segment congenital tracheal stenosis.     

Localization of ulnar neuropathy at the elbow using new stimulator for the inching test.

OBJECTIVE: To evaluate the usefulness of the TenElectrodes, a new stimulator for inching test, in the diagnosis and localization of ulnar neuropathy at the elbow (UNE). METHODS: Sixty-two ulnar nerves in 40 control subjects and 24 ulnar nerves in 23 patients with typical symptoms and signs of UNE were studied. The inching test of ulnar motor nerve using TenElectrodes was done along 8 cm across the elbow in the extended position. RESULTS: In the inching test of the control group, the mean segmental latency difference was 0.19+/-0.08 ms. Maximal latency difference over a 1 cm segment did not exceed 0.40 ms in any of the controls but exceeded 0.5 ms or more in all clinical UNE patients. In all UNE patients, the lesion sites were identified by the inching test using TenElectrodes: the retroepicondylar groove (54.2%), the humeroulnar arcade (29.2%), and dual compression (16.6%). CONCLUSIONS: TenElectrodes is a useful stimulator for the inching test in the diagnosis of UNE. The precise localization of compression was possible in all patients with UNE and the most common site was the retroepicondylar groove.
