Prospective comparative study of intraoperative “Towel clip test” and “Vertical patella test” assessing lateral retinaculum tightness in patients undergoing TKA

BackgroundProper patellar tracking is one of the most important aspect of TKA to ensure good functional outcome. A patellar tracking problem noted intraoperatively serves as a warning sign and should prompt the surgeon to reassess position of each component. Various tests are there to assess lateral retinaculum tightness viz. "No thumb test", "Towel clip test". A new test "Vertical patella test" is described to assess lateral retinaculum tightness. A study was conducted to assess the effectiveness, correlation and validity of two techniques.Materials & MethodsPatients >50 years of age and with diagnosis of Osteoarthritis knee having less than 30 varus and flexion deformity going in for primary TKA were selected with a sample size of 100 knees in a tertiary care centre. Revision cases or patients with flexion contracture more than 30, complex knee surgery; with pre existing patellar tilt were excluded from study.ResultsResults of both tests were found to correlate in 75% of case with sensitivity of 96.65% and specificity of 75.00%. Kappa came out to be 0.634 which shows good agreement of vertical patella test and towel clip test. Result was computed using excel and SPSS and was found to be significant with p value< 0.05. Lateral retinaculum release was done in 8 knees.ConclusionsVertical patella test correlates with towel clip test, is easy to perform and saves time. The limitation of our study was small sample size.     

Hem-o-lok结扎锁在后腹腔镜肾切除术肾蒂血管处理中的应用

目的:探讨后腹腔镜肾切除术中应用Hem-o-lok结扎锁处理肾蒂血管的价值。方法:我们为63例患者行后腹腔镜肾切除术并采用Hem-o-lok结扎锁处理肾蒂血管,其中肾动脉近端用大号Hem-o-lok2枚结扎,远端用2枚钛夹夹闭后剪断,肾静脉用加大号Hem-o-lok近端2枚、远端1枚结扎后剪断。结果:本组手术时间90~255min,平均135min;出血量20~180ml,平均45ml;术后住院时间5~8d;术中肾蒂血管处理满意,术中、术后未发生严重并发症。结论:腹腔镜肾切除术中用Hem-o-lok结扎锁分别处理肾动静脉,安全可靠,经济实用,值得临床推广应用。     

两种艾灸法对二肾一夹型高血压大鼠血压和血管内皮细胞内分泌功能的影响

目的:应用两种艾灸疗法治疗两肾一夹肾血管性高血压大鼠(2K1C-RHR),评价这两种艾灸疗法的降压作用,并对其降压机理作初步的探讨。方法:建立2K1C-RHR模型,并将其随机分为六组:灸法Ⅰ组(百会、神阙、足三里)、灸法Ⅱ组(关元、涌泉、足三里)、卡托普利组、灸法Ⅰ+卡托普利组、灸法Ⅱ+卡托普利组、高血压对照组,另设正常对照组。经过10天治疗后,测量血压,并测定血浆中内皮素(ET)、一氧化氮(NO)。结果:高血压对照组的收缩压(SBP)、舒张压(DBP)明显高于正常对照组,各治疗组的SBP、DBP明显低于高血压对照组(P<0.01),各治疗组间则没有明显差异(P>0.05)。血浆NO含量各组间没有明显差异(P>0.05)。各治疗组与正常对照组的血浆中ET含量明显低于高血压对照组(P<0.01)。各治疗组ET/NO比值接近正常对照组(P>0.05)且明显低于高血压对照组(P>0.05)。结论:两种艾灸疗法有良好的降压作用,其降压机理与及纠正ET与NO的失衡状态有关。     

Modified Kalish osteotomy: A simple approach to minimizing proximal dorsal stress risers

Proximal dorsal stress risers are a potential complication to the Kalish osteotomy. The authors describe a modification to this osteotomy that is simple and effective. Since performing the wing-clip modification, there have been no observed stress risers.

Spontaneous esophageal rupture managed with endoscopic closure using an over-the-scope clip: A case report

Introduction and importanceSpontaneous esophageal rupture is a life-threatening condition caused by a sudden increase in the intraesophageal pressure. While surgery is the mainstay of management for spontaneous esophageal ruptures, in recent years, an increasing number of patients have been managed with endoscopic interventions. We report a case of spontaneous esophageal rupture managed with endoscopic closure using an over-the-scope clip (Ovesco Endoscopy AG, Tübingen, Germany).Case presentationA 68-year-old female presented with epigastric pain and left-sided back pain following vomiting. A computed tomography scan revealed mediastinal emphysema and an esophagogram showed leakage from the left side of the lower thoracic esophagus into the mediastinum. The patient was diagnosed with spontaneous esophageal rupture localized to the mediastinum and was treated conservatively. However, she had persistent fever and continuing esophageal leakage on the esophagogram. On the 12th day of admission, a gastrointestinal endoscopy was performed, which found a 10-mm full-thickness longitudinal laceration on the left side of the lower esophagus. Endoscopic closure using an over-the-scope clip was performed. The next day, the patient became afebrile. One week later, esophagogram revealed slight residual leakage and an additional endoscopic closure using an over-the-scope clip was performed; the patient subsequently had an uneventful recovery and was discharged on the 44th day of admission.Clinical discussionEndoscopic closure using an over-the-scope clip led to a good outcome in this patient with spontaneous esophageal rupture.ConclusionEndoscopic closure using an over-the-scope clip is an effective and minimally invasive technique for selected patients with spontaneous esophageal rupture.     

Diet components can suppress inflammation and reduce cancer risk

Epidemiology studies indicate that diet or specific dietary components can reduce the risk for cancer, cardiovascular disease and diabetes. An underlying cause of these diseases is chronic inflammation. Dietary components that are beneficial against disease seem to have multiple mechanisms of action and many also have a common mechanism of reducing inflammation, often via the NFκB pathway. Thus, a plant based diet can contain many components that reduce inflammation and can reduce the risk for developing all three of these chronic diseases. We summarize dietary components that have been shown to reduce cancer risk and two studies that show that dietary walnut can reduce cancer growth and development. Part of the mechanism for the anticancer benefit of walnut was by suppressing the activation of NFκB. In this brief review, we focus on reduction of cancer risk by dietary components and the relationship to suppression of inflammation. However, it should be remembered that most dietary components have multiple beneficial mechanisms of action that can be additive and that suppression of chronic inflammation should reduce the risk for all three chronic diseases.
