Objective To investigate the risk factors for postoperative arytenoid dislocation.
Methods From September 2003 to August 2013, the records of 16 patients with a history of postoperative arytenoid dislocation were reviewed. Patients matched in terms of date and type of procedures were chosen as the controls (n=16). Recorded data for all patients were demographics, smoking status, alcoholic status, preoperative physical status, airway evaluation, intubation procedures, preoperative laboratory test results, anesthetic consumption and intensive care unit stay. For arytenoid dislocation cases, we further analyzed the incidences of the left and right arytenoid dislocation, and the outcomes of surgical repair and conservative treatment. Categorical variables were presented as frequencies and percentages, and were compared using the chi-squared test. Continuous variables were expressed as means±SD and compared using the Student’s unpaired t-test. To determine the predictors of arytenoid dislocation, a logistic regression model was used for multivariate analysis.
Results Sixteen patients with postoperative arytenoid dislocation were enrolled, with a median age of 52 years. Most postoperative arytenoid dislocation patients (15/16, 93.75%) received surgical repair, except one patient who recovered after conservative treatment. None of the postoperative arytenoid dislocation patients were smokers. Red blood cell (P=0.044) and hemoglobin (P=0.031) levels were significantly lower among arytenoid dislocation cases compared with the controls.
Conclusions Non-smoking and anemic patients may be susceptible to postoperative arytenoid dislocation. However, neither of them was independent risk factor for postoperative arytenoid dislocation.

Objective To investigate the schistosomiasis japonica infection and preventive knowledge of immigration popula-tion in Jinshan District,Shanghai so as to provide the evidence for improving the control work. Methods The immigration popula-tion from schistosomiasis endemic provinces and local people were screened by serum IHA screening for schistosome infection, and the positives were further examined by Kato-Katz technique and the miracidium hatching method. The schistosomiasis preven-tive knowledge and behaviors were investigated by questionnaires. Results A total of 579 were investigated with 348 immigration people and 231 local people,and among them,the male accounted for 72.0%and female accounted for 28.0%. In the immigration population,the main age group was 20-29(56.0%),and 56.6%of the immigration had an education level at senior middle school or higher. The most proportion of immigration was from Anhui Province(36.2%). There were 4 IHA positive persons(1.15%)in the immigration,and 1 was positive in the stool test,and the schistosome infection rate was 0.29%. There were no positives in the local people. The schistosomiasis preventive knowledge of the immigration was generally poor,and some people’s behaviors of see doctor and medication were incorrect. Conclusion There are schistosome infected persons among the immigration population from schistosomiasis endemic provinces,and their schistosomiasis prevention knowledge was poor,thus there is a schistosomiasistransmission risk.

Objective To evaluate the effectiveness of bioelectrical impedance analysis(BIA) interventions on volume status in hemodialysis patient. Methods Searched The Cochrane Library, PubMed, EMbase, EBsco, Wanfang Data, China Biology Medicine, China National Knowledge Infrastructure to collect clinical trials. The retrieval time was from database to July 15, 2016. The studies were selected according to the inclusion and exclusion criteria and were critically appraised by two reviewers. Then the data of included studies were extracted. Meta-analysis was conducted by using RevMan 5.3 software and descriptive analysis. Results Ten clinical trials were included six random control trial, one controlled clinical trail, three longitudinal study, involving 2009 patients. The results of Meta-analysis showed that the effectiveness of BIA interventions on volume management could improve blood pressure (P=0.001), protect the heart function(left ventricular mass index,P=0.002), compared with the clinical evaluation method, the BIA assessment of dry weight of hemodialysis patients could reduce hospitalization rate 14%. Descriptive analysis showed that BIA intervention volume management had certain advantages for the survival benefit of patients, but the current research was still few, had not yet come to a certain conclusion. Conclusions BIA can improve the management of the volume status and dry weight of hemodialysis patients, so as to it can improve the clinical benefit and survival benefit of patients.Better methods and guidelines for assessing DW and using BIA need to be developed.We propose that experienced HD nursing staff be trained in the use of the BIA to help monitor patient over hydration and approximate dry weight in consultation with the nephrologists responsible for the care of these patients so as to obviate excessive residual over hydration between nephrology reviews.
