Through dissection of 12 fresh finger specimens, the anatomy of the distal part of dorsal aponeurosis and its function was closely observed. A direct reparative procedure of the terminal tendon by using tendon flap graft was deseribed for the treatment of chronic mallet finger deformity. Correction of deformity, restoration of active motion of DIP and avoidance of residual pain were observed in three clinical cases.
ObjectiveTo analyze the current situation of adaptation guidelines. MethodsCBM, CNKI, VIP, WanFang Data, PubMed, EMbase, GIN, SIGN, NICE and AHRQ databases were electronically searched to collect studies related to adaptation guidelines from inception to August 31th, 2020. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Descriptive analysis was then conducted on the general situation of the adaptation guidelines. ResultsA total of 83 studies were included, involving 63 full-text studies, 16 methodological studies and 4 secondary studies. The quantity of published articles of the adapted guidelines had an overall upward trend, and 48.39% of the adapted guidelines were published in UK-hosted journals. 51.81% of the adapted guidelines reported receiving funding or project funding during the development process, and 67.46% reported information of conflict of interests. Among the 33 adaptation guidelines published in the past five years, 33.34% reported their methodology used ADAPTE, 6.1% reported their methodology used GRADE-Adolopment, and 60.56% did not report the adaptation method. ConclusionsAt present, the international research on the adapted guideline is extensive, however, it is still in its infancy in China. The adaptation guideline is also required to be based on a theoretical framework, standardize the development of methodology, and ensure the quality of the adaptation guideline.
Objectives
To evaluate the effect of preoperative body mass index (BMI) on the perioperative and long-term results in esophageal squamous cell cancer patients.
Method
We retrospectively analyzed the clinical data of 503 patients with esophageal cancer between January 2001 and December 2009. There were 268 males and 235 females with the median age of 57 years ranging from 32-88 years. The associations between preoperative BMI and clinic patholo-gical characteristics were assessed by using the χ2 or Fisher's exact test. Survival analysis was performed by Kaplan-Meier curves with log-rank tests.
ResultsThe 1-year, 3-year, 5-year, and 10-year overall survival rate for the entire cohort of patients was 64.0%, 49.0%, 43.0%, and 41.0% respectively. The occurance rates of weight loss, lymph node metastases, and poorly differentiated tumorigenesis represented statistically higher in patients with BMI≤18.5 kg/m2 than those in the patients with BMI>18.5 kg/m2 (P=0.026, P=0.006, P=0.048). For the cohort, the Kaplan-Meier survival analysis showed a significant trend toward a decreased survival in esophageal cancer patients with underweight (P=0.001). No statistical difference in overall complication, anastomotic leakage, and pulmonary complication rate was detected among the different BMI classes(P=0.162, P=0.590, P=0.376). Univariate and multivariate analysis showed that the drinking status, pathological stage, and underweight were the independent prognostic factors.
ConclusionsAfter esophagectomy, BMI is not associated with the incidence of postoperative complications in patients. Patients with underweight are usually diagnosed with advanced stage, therefore tend to have poorer survivals than those with normal or over-weight.
Objective To analyze different characteristics of extra-vascular lung water ( EVLW) in the patients with acute respiratory distress syndrome( ARDS) , and examine its prognostic value. Methods 23 patients with ARDS admitted between November 2010 and December 2011 were divided into a survival group( n=13) and a dead group( n =10) according to the outcome. The hemodynamic status including extravascular lung water index( EVLWI) was measured in 3 consecutive days, and the relationship between EVLWI and the prognosis of patients was analyzed. Results On the first day of diagnosis, the EVLWI was higher in both groups in comparison with normal value. It was ( 13. 9 ±3. 45) mL/kg in the survival group and ( 14. 87 ±5. 75) mL/kg in the dead group( P gt;0. 05) . However, on the second day, the EVLWI in the survival group dropped significantly after intensive intervention, but the patients in the dead group did not respond well to the treatment and the EVLWI declined slightly. The EVLWI of both groups began to diverge significantly fromeach other, showing average value of ( 11. 07 ±2. 51) mL/kg and ( 15.63 ±5. 05) mL/kg, respectively( P lt; 0. 05) . On the third day, this difference between two groups was still more remarkable, resulting in ( 10.32 ±1.57) mL/kg vs. ( 16. 6 ±4. 33) mL/kg( P lt; 0. 01) . Conclusions The changes of EVLWI can be used to evaluate the effectiveness of treatment and predict the prognosis of patients with ARDS. EVLWI would likely be an indicator to evaluate the pulmonary capillary leakage.
Objective
To investigate the clinical value of " O”continuous biliary-enteric anastomosis combined with percutaneous transhepatic cholangial drainage (PTCD) in pancreaticoduodenectomy (PD).
Methods
The clinical data of 35 patients with PD who were admitted to Xinyang Central Hospital from June 2015 to June 2017 were retrospectively analyzed.
Results
All patients completed the " O” continuous biliary-enteric anastomosis combined with PTCD without perioperative death. ① The preoperative indwelling time of PTCD tube was (13.24±3.39) d, total bilirubin (TBIL) was (363.67±12.26) μmol/L on admission and (155.59±17.63) μmol/L on preoperative after PTCD, respectively. ② The operative time was (231.46±18.69) min, the intraoperative blood loss was (158.30±31.33) mL, the diameter of the hepatic ductal segment was (1.3±0.2) cm, and the duration of the " O” continuous biliary-enteric anastomosis was (7.31±1.52) min. ③ After surgery, the indwelling time of PTCD tube was (8.13±1.49) d, the hospitalization time was (27.31±5.49) d. Biliary leakage occurred in 1 case, pancreatic fistula occurred in 5 cases (3 cases of biochemical sputum and 2 cases of B-stage pancreatic fistula), abdominal infection occurred in 2 cases, pneumonia occurred in 3 cases, wound infection occurred in 2 cases. No postoperative biliary-enteric anastomosis stenosis, biliary tract infection, and intra-abdominal hemorrhage occurred. There was no laparotomy patients in this group and all patients were discharged. ④ All patients were followed-up for 180 days after surgery. No death, bile leakage, biliary-enteric anastomotic stenosis, biliary tract infection, pancreatic fistula, gastro-intestinal leakage, and abdominal infection occurred. One case of delayed gastric emptying and 2 cases of alkaline reflux gastritis were cured after outpatient treatment.
Conclusions
The preoperative PTCD can improve the preoperative liver function and increase the security of PD. " O” continuous biliary-enteric anastomosis is simple, safe, feasible, and has the function of preventing biliary-enteric anastomosis stenosis. For severe jaundice patients with blood TBIL >170 μmol/L, the " O” continuous biliary-enteric anastomosis combined with PTCD is an alternative surgical procedure for PD.
ObjectiveTo observe the choroidal vascularity index (CVI) and the subfoveal choroidal thickness (SFCT) of central serous chorioretinopathy (CSC), and to compare the stability and consistency of the two methods of measurement.MethodsA retrospective study. Thirty-one patients with unilateral acute CSC who visited the Department of Ophthalmology of Beijing Friendship Hospital for the first time during the period from Nov 1st, 2016 to Mar 18th, 2018 were included in the study. Thirty-one healthy age-matched subjects were enrolled as controls. All CSC affected eyes and their fellow eyes and healthy eyes were scanned by single-line enhanced depth imaging of OCT through central fovea of macula to measure their SFCT. The image was binarized and then the CVI of a 1500 μm range below fovea was calculated, i.e. the ratio of vascular (or lumen) area to total choroidal area. CVI and SFCT were compared among CSC eyes, fellow eyes and healthy eyes by variance analysis. Intra-group correlation coefficient (ICC), Bland-Altman curve and coefficient of variation (CV) were used to analyze the repeatability, consistency and stability of CVI and SFCT; and Medcalc18.2.1 software was used to draw the Bland-Altman curve and observe the consistency of the two measurement methods.ResultsThere were statistically significant differences in CVI and SFCT between CSC affected eyes and fellow eyes (t=3.470, 2.844; P=0.001, 0.006), CSC affected eyes and healthy eyes (t=6.977, 6.277; P＜0.001,＜0.001), fellow eyes and healthy eyes (t=3.508, 3.433; P=0.001, 0.001). Relative consistency analysis of CVI and SFCT showed that the ICC of single measurement and average measurement of CVI were 0.967 and 0.983 respectively, and that of single measurement and average measurement of SFCT were 0.937 and 0.967 respectively. The consistency of CVI and of SFCT was very good. The ICC value of CVI was slightly higher than that of SFCT. The results of repeatability analysis of CVI and SFCT showed that the difference between the two CVI measurements was smaller, and the difference between the two SFCT measurements was larger. And CVI and SFCT stability analysis results showed that the CV of CVI and SFCT were 10.5% and 25.3% respectively. CVI has smaller CV than SFCT.ConclusionsCompared with healthy eyes, CVI and SFCT are increased in CSC affected eyes and fellow eyes. And compared with SFCT, CVI has better consistency, repeatability and stability.
