RESUMO
Objective:To examine the risk factors for neuropathic pain (NP) after a spinal cord injury (SCI).Methods:A total of 115 patients with a SCI were analyzed retrospectively. They were divided into an NP group of 53 and a non-NP group of 62 according to the occurrence of NP. Gender, age, length of stay, occupation, level of education, cause of injury, spinal fracture, degree of SCI, the injury′s plane and complications at admission (diabetes, hypertension, anemia, venous thrombosis, pressure sores, urinary tract infection or hypoproteinemia) were recorded. T-tests and chi-squared tests were used to compare those factors between the two groups, and multivariate logistic regressions were evaluated to identify the risk factors for NP.Results:Twenty-three of the 53 cases of NP (43%) had developed within 1 month of the SCI. Thirty-seven (75%) experienced pain below the plane of the SCI. The main features reported were squeezing (34%) and numbness (26%). The multivariate logistic regression showed that the occurrence of NP was most strongly related to gender (women being particularly at risk) and venous thrombosis at admission.Conclusions:Women are at particular risk of feeling NP after an SCI, and venous thrombosis is an independent risk factor. NP should be diagnosed and treated quickly to reduce the negative impact on patients′ life quality.
RESUMO
Objective To investigate the incidence of electrocoagulation syndrome after endoscopic submucosal dissection (ESD) in the colorectal laterally spreading tumors (LST) and the risk factors. Methods Data of 51 patients with coloretral LST,treated with ESD from January 2010 to May 2014 at Shengjing hospital affiliated to China Medical University,were reviewed.The incidence of electrocoagulation syndrome was analyzed and logistic regression was used to evaluate risk.Results The incidence of electro-coagulation syndrome was 9.8%(5 /51).The incidence of tumors in the rectal area(7.1%,2 /28)was lower than that of the left half colon (12.5%,1 /8),and the right colon (13.3%,2 /15).Multivariable logistic regression analysis showed that the independent risk factors for the development of electrocoagulation syndrome were LST located in non-rectum area (OR =1.655,P <1.655),lesion size larger than 25 mm (OR =1.028, P <0.05),the operation time longer than 129 min (OR =1.016,P <0.05),age older than 62 year old (OR =0.987,P <0.05).Conclusion For the patients aged over 62 year old,lesion size larger than 25 mm,the operation time longer than 129 min and LST located outside the rectum,the mucous membrane should be separated from the muscularis propria in the ESD procedure to reduce electrocoagulation time as much as possible. In the postoperative period,patients need fasting,fluid replacement support,and prevention of post endoscopic submucosal dissection electrocoagulation syndrome (PEECS).
