ABSTRACT
Objective To investigate the clinical features and prognostic factors of extrahepatic biliary neuroendocrine neoplasms(EB-NENs).Methods The clinical data and survival of 21 patients with EB-NENs admitted from May 2014 to May 2018 were analyzed retrospectively.Results These 21 EB-NENs patients accounted for 1.6％ (21/1313) of all biliary tract neoplasms treated during the study period.Seven (33.3％) cases had lymph node metastasis.Five (23.8％) suffered from distant metastasis.The follow up time was (4 ～ 46.5) months with median survival time of (23.23 ± 4.17) months.Univariate analysis showed that the risk factors for survival were tumor TNM stage (x2 =9.066,P =0.003),lymph node metastasis(x2 =6.399,P=0.011) and distant metastasis (x2 =9.808,P=0.002).By multivariate analysis,independent risk factors were tumor TNM stage (P =0.008,RR =3.003,95％ CI:1.332 ～ 6.774),lyraph node metastasis (P =0.023,RR =5.382,95 ％ CI:1.261 ～ 22.971) and distant metastasis or not(P =0.007,RR =7.423,95％ CI:1.730 ～ 31.851).Conclusion EB-NENs was a rare malignant tumor with poor prognosis.Tumor TNM stage,lymph node metastasis and distant metastasis were independent prognostic factors for EB-NENs patients.
ABSTRACT
Objective To analyze the risk factors of nosocomial infection in Department of Neurosurgery and to provide evidence for the prevention and treatment of infection.Methods A total of 931 patients with neurosurgery operation in our hospital from January 2012-January 2016 were collected medical history data immediately after admission,including age,gender,underlying diseases,and primary diseases.Surgical records include preoperative white blood cell count,blood glucose level before operation,duration of operation,and reoperation.Hospitalization records include hospitalization time,without the use of corticosteroids,with or without the use of proton there is no pump inhibitor,and tracheal intubation / incision.Patients were divided into infection group and non infection group according to whether the hospital infection occurred during hospitalization.The difference of two groups of clinical data with statistically significant variables was Logistic multivariate regression analysis.Results There were 112 patients with nosocomial infection,the infection rate was 12.03％,and the infection occurred in the postoperative 3-25 d.The main infection site was postoperative wound,accounting for 35.7％;respiratory tract,accounting for 34.8％.There were 64 strains of pathogenic bacteria,81 strains of Gram-negative bacteria,accounting for 64.1％,21 strains of gram positive bacteria,accounting for 32.8％,2 strains of fungi,accounting for 3.1％.There were significant difference between infection group and non infection group in ≥ 60 years,with basic diseases,reoperation,combined with other injuries,white blood cells,abnormal preoperative hyperglycemia,glucocorticoid use,proton pump inhibitors use,tracheotomy,hospitalization time,operation time (P ＜ 0.05).Further Logisitc regression analysis showed that age,reoperation,hospitalization time,preoperative high blood sugar and tracheotomy were the risk factors of nosocomial infection in Department of neurosurgery.Conclusions For the older,reoperation,longer hospitalization time,preoperative hyperglycemia and tracheotomy patients can take specific measures to improve the immunity of the patients,the rational use of antimicrobial drugs to avoid the occurrence of postoperative infection.
ABSTRACT
Objective To investigate the clinical characteristics and related risk factors of infarction secondary to severe traumatic brain injury.Methods 480 traumatic brain injury patients were chosen.Depending on the occurrence of cerebral infarction,patients were divided into TCI groups and non-TCI group,clinical symptoms and signs of TCI group were observed,and its related risk factors was analyzed.Results In 480 cases patients,there were 30 cases of patients with traumatic brain injury secondary to cerebral infarction,the rate was 6.25%.Clinical manifestations included unilateral limb motor and sensory dysfunction,visual dysfunction,language dysfunction,dizziness,headache.10 cases Prognosis were good,6 cases were mild disability,3 cases were severe disability,1 case was plant survival,10 patients died.Univariate analysis showed that the rates of aged ≥50 years,GCS score ＜ 8 points,hernia,hypotension,subarachnoid hemorrhage,large doses of non-dehydrating agent in the TCI group were higher than those of non-TCI group,the differences were statistically significant (x2 =12.311 3,14.725 4,19.867 8,5.296 9,9.242 6,11.713 6,all P ＜ 0.05).Logistic multivariate analysis showed that age ≥50 years,GCS score ＜ 8 points,hernia,cerebral hypotension were important risk factors.Conclusion Brain injury patients with cerebral infarction secondary to clinical manifestations have some characteristics.Age ≥50 years,GCS score ＜ 8 points,hernia,hypotension are important risk factors.
ABSTRACT
Objective A scientific evaluation of hospital culture with the Dimension organizational culture model, in view of features of China's general public hospitals.Methods Based on Denison model, according to the characteristics of the public general hospitals in China, the authors developed a tool for organizational culture assessment (TOCA) by using the survey data from 87 hospitals in three provinces from the East, Central, and West areas in China.Results This tool, an evaluation scale, comprises the four cultural characteristics of direction, consistency, participation, and adaptability, as well as 13 cultural dimensions of social responsibility and competitive consciousness. The tool is tested as having good internal reliability and validity.Conclusion The TOCA provides hospital administrators with a tool for hospital culture evaluation, diagnosis and improvement.
