BACKGROUND:Surgical treatment for pigmented vil onodular synovitis can maximize the excision of synovial lesions and recovery of joint function.
OBJECTIVE:To investigate the knee joint function and relapse rate fol owing treatment of pigmented vil onodular synovitis with total knee replacement and arthroscopic synovectomy.
METHODS:We retrospectively analyzed 34 cases of knee pigmented vil onodular synovitis admitted for surgical treatment in the Department of Orthopedics, Xiangya Hospital of Central South University, China from December 2006 to December 2011. In these cases, 24 patients received arthroscopic synovectomy and 10 patients were subjected to total knee replacement. Adjuvant radiotherapy was conducted according to postoperative patient’s conditions. Lysholm scoring was employed in the arthroscopic synovectomy group, and American Knee Society scoring was used in the total knee replacement group. Knee function in two groups was compared before and after treatment. Fol ow-up observation was performed to compare knee function recovery and relapse rate between two groups.
RESULTS AND CONCLUSION:Thirty-four patients were effectively fol owed up for 12-66 months, mean 41.3 months. Statistical analysis showed that in the arthroscopic synovectomy group, the postoperative Lysholm score was (86.3± 10.3) points, significantly higher than the preoperative score which was (55.5±13.2) points (t=3.81, P=0.016, P<0.05). In the total knee arthroplasty group, the American Knee Society score was increased from (40.7±2.2) points preoperatively to (90.2±1.1) points postoperatively (t=6.27, P<0.01). In the arthroscopic synovectomy group, the American Knee Society score was increased from (34.2±3.9) points preoperatively to (80.8±1.9) points postoperatively (t=16.58, P<0.01). Arthroscopic synovectomy combined with adjuvant radiotherapy can achieve better outcomes in pigmented vil onodular synovitis patients, while the total knee replacement for advanced with advanced knee diffuse pigmented vil onodular synovitis is better to restore knee function and the recurrence rate is low.

Objective:To evaluate the value of vasoactive-inotropic Score (VIS) at different time points in predicting the 28-day mortality of patients with septic shock, so as to reduce the risk of death and improve the prognosis of patients.Methods:This experiment was a single-center retrospective cohort study. The clinical data of 275 adult patients with septic shock who were treated with vasoactive drugs in the intensive care unit of the Affiliated Hospital of Xuzhou Medical University from February 2016 to February 2020 were collected. According to the 28-day survival condition, all recruited patients were divided into the death group and the survival group, and the maximum vasoactive-inotropic score of all patients at the first 24 h and the second 24 h were calculated, which were expressed as VIS max24 and VIS max48. Multivariate logistic regression analysis was used to find the independent risk factors that influencing the prognosis. The receiver operating characteristic curve was used to analyze the predictive value of VIS. Results:There was no significant difference between the death group and the survival group in the characteristics including age, sex, weight, infection sites, blood culture results, cardiac arrest, hormone use, and 24 h rehydration volume ( P>0.05). APACHE II score, basic lactic acid, and lactic acid after 24 h of treatment were increased significantly in the death group ( P<0.05). VIS max24 could accurately predict the 28-day mortality (AUC=0.953, 95% CI: 0.924-0.982), which were more efficent compared to VIS max48 (AUC=0.919, 95% CI: 0.881-0.957), basic lactic acid (AUC=0.937, 95% CI: 0.900-0.966) and APACHEⅡ score (AUC=0.865, 95% CI: 0.818-0.913). Conclusion:VIS max24 can more accurate predict the 28-day mortality in patients with septic shock.

Objective To investigate the clinical value of CT lymphangiography (CTL) combined with direct lymphangiography (DLG) in primary intestinal lymphangiectasia (PIL). Methods Sixteen patients diagnosed as PIL with intestinal enteroscopy were recruited in this retrospective study. All the patients were performed DLG and CTL one week before exploratory laparotomy. Subjective assessment in DLG included weak lymphatic fluid drainage, lymphangiectasia, lymphatic reflux, fistula and thoracic outlet reflux or obstruction. While for CTL combined with DLG, the intestinal and extra-intestinal lesions were evaluated, including lymph node, edema, lymphangiectasia and abnormal distribution, fistula, and lymphangiomatosis. All the diagnosis was compared with intestinal endoscopy results. Results For DLG, 16 weak lymphatic fluid drainages, 9 lymphangiectasia, 1 fistula with abdomen and 14 thoracic outlets weak lymphatic fluid drainage or obstruction were found. For DLG combined with CTL, 16 intestinal lumens dilatation and 14 circumferential intestinal thickening were found in intestinal lesions. While for extra-intestinal lesions, the imaging features included edematous findings (12 in mesentery, 7 ascites only, 2 hydrothorax and ascites, and 3 pericardial, thoracic and abdominal effusions), abdominal lymph nodes (6 cases), lymphangiectasia and abnormal distributions (14 cases), fistulas (lymph-intestinal luminal fistula in 4 cases, and lymph-abdominal fistula in 3 cases), lymphangiomatosis (3 cases), and thoracic duct outlet dysfunction and reflux (14 cases).The number of cases diagnosed as intestinal lymphangiectasia, intestinal luminal lymph exudation and lymph fistula were 16, 10 and 6 with intestinal endoscopy, while the number were 11, 0, and 4 with CTL combination with DLG. Conclusion Combination of CTL with DLG is valuable in the diagnosis of PIL.
