Periodontal mechano-sensory responses following trauma to permanent incisor teeth in children

Abstract –  The aim of this study was to investigate mechano-sensory responses of injured and uninjured incisor teeth. Twenty-five children who had experienced dental trauma, together with age- and gender-matched controls, were studied prospectively. Touch thresholds of incisor teeth from both groups were determined using calibrated sets of von Frey hairs (force range 0.5–10.0 g in 0.5 g increments) using a forced choice staircase method. Forces were applied perpendicular to the buccal enamel surfaces along the midline, 2 mm from the incisal edge. Touch threshold was defined as the lowest force detected in three out of the five occasions. Following statistical analysis, P  < 0.05 was considered significant. At initial examination, the touch threshold values of 25 traumatised teeth were significantly greater than the untraumatised controls ( P  < 0.001), and these values approached those of the control teeth over 3–12 months ( P  > 0.05). Dental trauma was associated with increased touch thresholds in permanent incisor teeth, with recovery toward healthy control values usually occurring between 3–12 months.     

Primary papillary serous cystadenocarcinoma of broad ligament

A rare case of an advanced primary broad ligament carcinoma is discussed, with a review of the literature regarding its incidence, presentation and management. This patient showed a complete response to adjuvant cisplatin-based chemotherapy following panhysterectomy and is presently without any evidence of disease, 15 months after completion of her treatment.     

Augmentation technique with semitendinosus and gracilis tendons in chronic partial lesions of the ACL: clinical and arthrometric analysis

Most of the techniques described in the literature for the repair of chronic partial ACL tears, don’t spare the intact portion of the ligament. The aim of this study was to perform a prospective analysis of the results of augmentation surgery using gracilis and semitendinosus tendons to treat partial sub-acute lesions of the ACL. This technique involves an “over the top” femoral passage, which enables salvage and strengthening of the intact portion of the ACL. The study included 47 patients treated consecutively at our institute from 1993 to 1998, with a mean injury-surgery interval of 18 weeks (range 12–36). The patients were followed up by clinical and instrumental assessment criteria at 3 months, 1 and 5 years after surgery. Clinical assessment was performed using the IKDC form. Subjective and functional parameters were assessed by the Tegner activity scale. Instrumental evaluation was done using the KT-2000 instrument: the 30-pound passive test and the manual maximum displacement test were performed. We obtained good or excellent results in 95.7% of cases. No recurrences in ligamentous laxity were observed. We believe that the described technique has the advantage of being compatible with ACL anatomy, and enables very rapid functional recovery.     

国内关节镜下后交叉韧带重建术的现状与展望

后交叉韧带是维持膝关节稳定的重要结构,损伤后宜早期干预,才能减少并发症的发生并提高治疗效果。而关节镜下重建后交叉韧带是现有技术水平上最为理想的选择。本文就国内现有的应用较多的关节镜下后交叉韧带的重建术式、不同重建材料及重建固定技术进行总结和疗效比较。     

关节镜下可吸收螺钉固定腘绳肌重建膝后交叉韧带的疗效评价

目的 探讨关节镜下可吸收螺钉固定腘绳肌腱单束重建膝后交叉韧带(posterior cruciate ligament,PCL)的效果.方法 2004年4月～2005年4月,我院25例(25膝)经关节镜检查证实为PCL断裂,在关节镜下行自体腘绳肌腱单束PCL 重建术,生物可吸收挤压螺钉解剖位固定重建韧带. 结果 手术时间平均90min(80～100min).25例膝术毕PCL重建后后抽屉试验均为阴性.术后住院时间7～14 d,平均10.4 d.25例术后随访12～24个月,平均18个月,23例膝后抽屉试验阴性,2例后抽屉试验1级.术后12个月Lysholm膝关节功能评分由术前(44.8±8.1)分提高至(77.8±6.4)分(t=-15.999,P=0.000).按国际膝关节文件编制委员会膝关节标准评价膝关节功能分级,术前异常(C级)10例、显著异常(D级)15例,随访时正常(A级)8例、接近正常(B级)15例、异常(C级)2例(Z=-4.394,P=0.000). 结论 关节镜下可吸收螺钉固定自体腘绳肌腱单束重建膝PCL创伤小,固定可靠,手术操作简单,术后膝关节功能恢复效果好.     

Incarcerated internal hernia of the small intestine through a breach of the broad ligament: two cases and a literature review.

Two cases of internal herniation through a defect in the broad ligament of the uterus are described. Both were successfully treated laparoscopically. This rare condition should be borne in mind when a middle-aged woman presents with colicky lower abdominal pain. The cause is unknown, but both congenital and acquired origins have been proposed. As far as emergency situations are concerned, laparoscopy has proven to be both a diagnostic and a therapeutic tool.     

关节镜下胭绳肌腱部分重建、单束重建和双束重建前交叉韧带的疗效比较

目的 研究使用腘绳肌腱进行关节镜下前交叉韧带（ACL）损伤后部分重建、单束重建和双束重建的疗效差异。方法 本研究共包括56例ACL重建病例，其中部分重建11例，单束重建25例，双束重建20例。所有患者术前及随访时均进行IKDC2000、Tegner和Lysholm评分以及常规KT-2000和后推KT-2000测量，并对结果进行统计学分析。结果 平均随访19．84±5．03个月（13～22个月）。对三组的IKDC、Lysholm和Tegner评分的配对t检验显示，术后的IKDC、Lysholm和Tegner评分比术前均有显著改善。后推法KT-2000测量显示，ACL双束重建可以比单束重建获得更好的膝关节稳定性，ACL部分重建组膝关节的稳定性优于单束重建和双束重建组。但常规KT-2000测量无法辨别三种术式之间膝关节稳定性的差异。结论 ACL双束重建可以比单束重建更好地重建膝关节的稳定性，ACL部分重建的临床效果优于单束重建和双束重建；后推KT-2000测量在ACL双束重建和部分重建的术后稳定性评估上可能具有重要的应用价值。
