ABSTRACT
Objective To retrospectively analyze the distribution and drug resistance of pathogenic bacteria in urinary tract infection in Xiangyang Central Hospital from 2017-2019, so as to provide a basis for clinical treatment of urinary tract infection and rational use of antibiotics. Methods The pathogenic bacteria isolated from clinical urine culture in Xiangyang Central Hospital from January 2017 to December 2019 were collected, and BD PhoenixTM 100 was used for the identification of pathogens and antimicrobial sensitivity test. The WHONET 5.6 and GraphPad Prism 5.0 software were used for data analysis. Results A total of 3 056 strains of pathogens were isolated from 15 672 urine specimens (19.50%). Gram-negative bacteria accounted for 77.95%, of which E. coli was the most common (52.45%). Gram-positive bacteria accounted for 12.63%, including E. faecalis (4.80%) and E. faecium (4.80%). Fungi accounted for 9.50%. The clinical departments with the highest rates of urinary culture submission and positive detection were Urology (26.20%) and Endocrinology (41.90%), respectively. E. coli and K. pneumoniae had high resistance rates to piperacillin, compound trimethoprim, cefuroxime, ceftriaxone and cefazolin, all exceeding 50.00%, while P. aeruginosa was relatively sensitive to various antibiotics. The resistance rates of these three gram-negative bacteria to carbapenem antibiotics increased year by year. The isolated gram-positive cocci were mainly enterococcus faecalis and enterococcus faecalis. They were highly sensitive to linazolamide, vancomycin and teicoplanin, but the resistance rates to other types of antibiotics were quite different. The average detection rates of ESBLs-producing E. coli and K. pneumoniae were 52.90% and 59.00%, respectively. Conclusion The pathogens of urinary tract infections in Xiangyang Central Hospital from 2017 to 2019 are mainly gram-negative bacteria, and the resistance rate to carbapenem drugs is increasing year by year. The ESBLs-producing strains of E. coli and K. pneumoniae are highon should be strengthened in patients with high DOB value and smoking.
ABSTRACT
Objective@#To investigate the key issues in the diagnosis and treatment of foreign body aspiration in children with tracheobronchial variations.@*Methods@#A retrospective study was performed for 11 pediatric patients who were treated in Department of Otorhinolaryngology and Head and Neck Surgery, Henan Province People′s Hospital after a diagnosis of foreign body aspiration with tracheobronchial variations between January 2015 and December 2017. There were 7 males and 4 females among the 11 cases of foreign body aspiration with tracheobronchial variations, ranging between 9 months and 11 years of age.@*Results@#Among 11 cases, the types of variationswere tracheal bronchus in 9 cases, bridging bronchus in 1 case and simple tracheal stenosis in 1 case. All of the pediatric patients were under general anesthesia, and the foreign bodies were removed by bronchoscopy successfully with no significant complications.@*Conclusions@#The possibility of tracheobronchial variations should be considered in children with recurrent wheezing and poor efficacy of regular treatment before foreign body aspiration. Removal of foreign body via rigid bronchoscope under general anesthesia is a safe and effective treatment. These children are needed to combine the situation oftracheobronchial variations and the location of foreign bodies to guide the operation, and strengthened the perioperative treatment.
ABSTRACT
Objective To evaluate the growth and survival of single kidney transplants with donation after citizen death (DCD) donors from infants and children (＜3 years of age) to adults.Methods We retrospectively analyzed the data of single kidney transplants with donors from infants and young children to adults in our center.All the recipients were divided into infant donor group (≤3 years of age) and children donor group (1 year＜ age ≤3 years) in terms of the donor's age.The serum creatinine (SCr) level after surgery was determined and the major diameter of the kidney was measured by Doppler B ultrasonography.DGF,vascular complications,urinary tract complications,proteinuria,acute rejection,and infection were recorded during the follow-up period.Results There were 24 cases in infant donor group and 37 in children donor group.The mean follow-up period was 28 months.The SCr level at 1 st month post-transplantation was significantly higher in infant donor group than in children donor group (350.67 ± 35.57 μmol/L versus 193.70 ± 86.76 μmol/L),and the major diameter ((X-)± s) of the kidney in children donor group was significantly greater than that in infant donor group (78.29 ± 4.68 mm versus 93.62 ± 5.57 mm),but there was no significant difference during the subsequent 3-year follow-up period.The incidence of DGF in infant donor group was significantly higher than in children donor group,but there was significant difference in the rate of vascular complications,urinary tract complications,proteinuria,acute rejection,and infection between two groups.Conclusion The single kidney transplants from infants and young children to adults can grow rapidly,and their survival rate is relatively high.
