Clinical status of Sagliker syndrome: a case report and literature review

In a 53-year-old woman, Sagliker syndrome developed during 22 years of treatment with intermittent hemodialysis as a result of severe secondary hyperparathyroidism (SHPT) complicating end-stage renal disease. She failed medical managements and lost her renal graft just after the kidney transplantation due to acute rejection. Although surgical parathyroidectomy was effective, the parathyroid hormone level became extremely high again due to recurrent hyperparathyroidism. It is possible that such patient could survive long-term with dialysis, but prevention of severe SHPT is the most important.     

Clinical outcomes of second-look endoscopy after gastric endoscopic submucosal dissection: predictive factors with high risks of bleeding

Background

A second-look endoscopy is routinely performed after endoscopic submucosal dissection (ESD) in many institutions, although the need is questionable. Additional hemostatic procedures might be necessary for the post-ESD ulcer with a high risk of bleeding. We investigated the predictive factors for post-ESD ulcers with a high risk of bleeding.

Methods

Second-look endoscopy was performed on the day following ESD. The post-ESD ulcers were categorized into two risk groups according to the Forrest classification: high-risk ulcer stigma (type I and IIa) and low-risk ulcer stigma. We analyzed the risk factors associated with high-risk ulcer stigma and late delayed bleeding.

Results

During the study period, 616 ESD procedures were performed. Second-look endoscopy revealed that the incidence of high-risk ulcer stigma post-ESD was 15.1 %. Early and late delayed bleeding rates were 3.7 and 1.9 %, respectively. Multivariate analysis revealed that submucosal fibrosis and nausea were significantly related to high-risk ulcer stigma after ESD. Multivariate analysis revealed that surface erosion, location of the lesion, and high-risk ulcer stigma identified by second-look endoscopy were significantly associated with late delayed bleeding.

Conclusions

The effective use of selective second-look endoscopy will help limit unnecessary procedures. Submucosal fibrosis and nausea were risk factors associated with high-risk ulcer stigma after ESD.     

Hamstring tendon autograft versus LARS artificial ligament for arthroscopic posterior cruciate ligament reconstruction in a long-term follow-up

Introduction

Surgical reconstruction has been increasingly recommended for the surgical management of posterior cruciate ligament (PCL) ruptures. While the choice of tissue graft still remains controversial. Currently both hamstring tendon autograft (HTG) and ligament advanced reinforcement system (LARS) artificial ligament are widely used but there are seldom reports on the comparisons of their clinical results. Our study was aimed to assess the effectiveness of these two grafts.

Materials and methods

Thirty-five patients with unilateral PCL rupture were enrolled in this retrospectively study. Sixteen of them received arthroscopically assisted PCL reconstruction using hamstring tendon autografts (HTG group) and nineteen using LARS ligaments (LARS group). All cases were followed up for 46–57 months with a mean of 51 months. Follow-up examinations included radiographic assessment, Lysholm score, Tegner score, International Knee Documentation Committee (IKDC) rating scales and KT-1000 test.

Results

All patients improved significantly at the final follow-up compared with the examinational results preoperatively and there were no significant differences between HTG group and LARS group with respect to the results of radiographic assessment, Lysholm score, Tegner score, IKDC rating scales and KT-1000 test.

Conclusions

Similar good clinical results were obtained after PCL reconstruction using hamstring tendon autografts and LARS ligaments. Both LARS ligament and hamstring tendon autograft are ideal grafts for PCL reconstruction.     

Risk factors for acute kidney injury (AKI) in infants with melamine-associated urolithiasis and follow-up: a multi-center retrospective analysis

An epidemic of urinary tract stones was noted among infants in China, 2008. This event was believed to be associated with consumption melamine-contaminated powdered formula. The patients with symptoms and clinical manifests had already been analyzed in our previous studies. In this study, our aim is to investigate the risk factors of melamine-associated acute kidney injury (AKI) and the potential relationship toward children growth in our five years follow-up. A total of 619 infants with melamine-associated urolithiasis were admitted into 20 different hospitals in the Gansu province, China. All clinical data were divided into AKI and control groups according to the occurrence of AKI. Univariate and multivariate analyses were performed with a logistic regression model to assess the independent risk factors of AKI. Logistic regression analysis revealed that the odds ratio (OR) of AKI was 19.62 in the group of infants who consumed Sanlu® milk powdered infant milk formula. A higher prevalence of AKI was observed in infants age of 6–11 months (OR: 9.59, p?p?p?相似文献   

体脂量是绝经后女性股骨近端骨强度的决定因素

正Lower body weight or body mass index(BMI)has been known to be higher risk of developing osteoporosis and low-energy fractures via mechanical loading and other factors in both men and women[1].Recently,there have been new insights into the relationships between body composition and bone health.However,most of the previous studies regarding the relative effect of body composition on bone mass yielded inconsistent     

阿朴吗啡神经保护作用的途径：随机对照动物实验

目的：观察急性注射10 mg/kg R-阿朴吗啡后的神经保护作用.方法：实验于2004-06/2005-03在武装警察部队总医院完成.结合微量透析法,26只Wistar大白鼠急性皮下注射阿朴吗啡10 mg/kg,通过水杨酸钠诱捉法来清除6-羟基多巴胺或1-甲基-4-苯基吡啶离子产生的羟自由基.透析液的2,3-双羟基安息香酸含量用高效液相色谱电化学法检测.结果：26只大鼠均进入结果分析.6-羟基多巴胺或氧化产物干预2,3-双羟基安息香酸形成,这种显著增加持续到整个试验.6-羟基多巴胺灌注3 h后,仍达基线值（180.9 nmol/L）的350%.在1-甲基-4-苯基吡啶离子（5mmol/L）灌注中,2,3-双羟基安息香酸水平降低和持续增加到基线值（50.8 nmol/L）的160%,显著增加透析液中2,3-双羟基安息香酸水平.结论：急性注射阿朴吗啡,不能清除6-羟基多巴胺或1-甲基-4-苯基吡啶离子产生的羟自由基,说明阿朴吗啡神经保护的作用不是通过抗羟自由基作用.     

护士在临床抗菌药物合理应用中的作用

据有关统计资料显示，中国住院患者抗菌药物的使用率高达80％，其中使用广谱抗菌药物和联合使用2种以上抗菌药物的比率达58％，远远高于30％的国际水平。我国每年约有20万人死于药品不良反应，其中40％以上是死于抗菌药物滥用。滥用抗菌药物的严重后果是细菌耐药性增强、严重的不良反应以及医疗费用的猛涨。中国已成为世界上细菌耐药最严重的国家之一。
