RESUMEN
Inguinal hernia is one of the common diseases in general surgery, and tension-free hernia repair is the most common treatment for inguinal hernia. Patch infection is the common complication after hernia repair, confuses many of the general surgeons for its complex condition and long duration. The pathogenetic factors of patch infection can be roughly divided into three aspects, which include patients' physical condition, operation details, material and structure of patch. Prevention in advance of the susceptible factors of mesh infection can significantly improve the prognosis of patients. As for the treatment of patch infection, there is no unified standard yet, and individual treatment plans should be formulated according to the patient's condition and experience of the clinician. This article reviews the latest research progress of the occurrence, diagnosis, prevention and treatment of patch infection after tension-free hernia repair.
RESUMEN
Objetive To explore bacteriological changes and susceptible factor of nosocomial infection in neonatal intensive care unit (NICU). Methods The clinical data from 5543 hospitalized neonates during January 2010 to December 2015 were retrospectively analyzed. Results Nosocomial infection rate during the study period was 8 . 75 %. The most common pathogen of nosocomial infection was Staphylococcus epidermidis, followed by Escherichia coli and Klebsiella pneumoniae. Respiratory infection accounted for 37.73% and blood infection 37.53%. 36.74% blood samples were tested to be positive, and 32.67% sputum were positive. In the first three years, the main pathogens of nosocomial infection were Candida albicans, Klebsiella pneumonia, and Staphylococcus aureus; in the last three years, the main pathogens were Staphylococcus aureus, Escherichia coli, and Klebsiella pneumoniae. The susceptible factors of nosocomial infection in NICU were gestational age?
RESUMEN
Objective To provide evidence for clinical diagnosis and treatment of staphylococcus peritonitis through retrospective analysis of peritoneal dialysis related clinical characters. Methods Patients who experienced staphylococcus peritonitis were observed as peritonitis group.Patients did not experience peritonitis were observed as one-to-one control group in order to investigate predictors of staphylococcus peritonitis,bacteria spectrum,antimicrobial resistance and clinical outcomes. Results There were 74 patients enrolled in either group.For patients in peritonitis group,Kt/V(1.74±0.03 vs 2.61±0.48,P＜0.01),CrCL[(55.82±2.22) ml/min vs (76.13±17.42) ml/min,P＜0.01],GFR [(1.32±0.55) ml/min vs (3.08±0.75) ml/min,P＜0.01],nutrition index,hemoglobin[(91.70±25.43) g/L vs (111.50±19.59) g/L,P＜0.01],potassium[(3.43±0.70) mmol/L vs (3.78±0.73) mmol/L,P=0.002],sodium [(137.09±5.06) mmol/L vs (140.57±3.55)mmol/L,P＜0.01],chloride [(98.31±6.14) mmol/L vs (101.52±4.58) mmol/L,P=0.001] and calcium [(2.23±0.24) mmol/L vs (2.31±0.22) mmol/L,P=0.04] in serum were significantly lower than those in control group.The morbidity of staphylococcus peritonitis was 0.030 episode per year in recent five yearn.The major strains were Staphylococcus epidermidis,followed by Staphylococcus aureus.Staphylococci were all sensitive to vancomycin,teicoplanin and linezolid.The cure rate was 89.19％,and mortality was 4.05％.Relapse rate of Staphylococcus epidermidis peritonitis was higher (40％) than other strains. Conclusions Poor nutrition,insufficient dialysis,longer followup interval,anemia,electrolytic imbalance are the risk factors of Staphylococcus peritonitis.The morbidity and mortality are lower than before.Staphylococcus epidermidis peritonitis has higher relapse rate and requires more attention to prevention and treatment.
RESUMEN
Objectives To understand the susceptible factors for tobacco use among doctors in Henan province.Methods A random multilevel cluster sampling method was conducted.2 990 subjects were studied with an inquiry and self-reported questionnaire.Results The total smoking rate was 27.5%.The current smoking rate was 22.3%.Daily smoking rate was 13.3%.The main reasons for smoking were social needs,pressure relief,getting refreshing.About 21.4% subjects smoked in front of patients.Majority doctors understood the relationship between smoking and some diseases.The multivariate analysis showed that the doctors'smoking behavior was related with his gender,age,education background,monthly revenue,working section,hospital administration level,knowledge scale of tobacco being harmful on health,knowledge scale on the relationship between smoking and illness,doctors'social norm attitude for smoking.Conclusions The smoking behavior of doctors was complex,which was related to personal,social environment factors.Only comprehensive smoking prevention interventions could be stressed to produce lasting behavior change.
RESUMEN
OBJECTIVE To investigate and know the site distribution,susceptible factors and antibiotic resistant condition in hospital-acquired infection by Enterococcus so as to provide reference for clinical preventive control and for reasonable uses of medicine.METHODS Sixty five Enterococcus strains isolated from different infection specimens in the hospital from 2001 to 2005 were analyzed,and examined their sensitivity to medicines.RESULTS Among 65 Enterococcus strains there were 36 strains of Enterococcus faecalis and 29 strains of E.faecium.The first three susceptible site diseases were alimentary,circulatory and injury.The site distributions were urinary tract,lower respiratory tract and surgical incisions.Related aggressive operations included urethra intubation,tracheal intubation,and surgery.Except for vancomycin and teicoplanin,E.faecalis was sensitive to ampicillin,high-level streptomycin,levofloxacin and nitrofurantoin,and E.faecium had antibacterial activity to chloramphenicol and tetracycline.There were 2 vancomycin-resistant Enterococcus(VRE) cases detected.CONCLUSIONS It is the easiest to examine and find Enterococcus in urine and the prevalence rate is high after related aggressive operations.The isolation rate of E.faecium is high and it has strong antibiotic resistance.Vancomycin is still the most sensitive medicine to Enterococcus.
RESUMEN
OBJECTIVE To explore the status of nosocomial infection,infection sites of patients and susceptible factors of infection in neuro-intensive care unit(NICU) in order to correspondently prevent and control the occurrence of nosocomial infection.METHODS The clinical data of 471 patients admitted to NICU from Mar 2005 to Feb 2006 were investigated retrospectively.RESULTS Out of 471 cases in one year,a total of 90 cases of nosocomial infection were found.The rate of nosocomial infection was 19.11%.Among the nosocomial infection sites,the respiratory tract was the most frequent one(46.67%).The second was urinary tract(44.17%).The patients aged of more than 60 years,or with urethral catheter,mechanical ventilation,vein intubations,or with long medical intubation suffered infection more susceptibly than other patients.The infection rate of nosocomial infection was significantly different from hospitalization group.Sex was not evidently related to nosocomial infection.CONCLUSIONS The rate of nosocomial infection in NICU is largely higher than the total rate of infection.The susceptible factors are age,long-term hospitalization,invasive operations and long medical intubation.
RESUMEN
Objective To study the adverse effects of outdoor air pollution on children's respiratory system health in Anshan city. Methods 1951 children were randomly selected from three areas with different degree of air pollution in Anshan city. The parents of the children were asked to answer a questionnaire about their children's respiratory health and home environment. The data of health were collected included persistent cough, persistent phlegm, asthma, current asthma, wheeze, and wheeze symptom. Results The prevalence rates of persistent cough, persistent phlegm, asthma, current asthma, wheeze and wheeze symptom were 9.48%, 4.82%, 1.33%, 0.92%, 6.30% and 4.97% respectively. Outdoor air pollution was a risk factor for persistent cough and persistent phlegm. The respiratory symptoms increased as the house became near to the main traffic lines. Combined effect of susceptible factor and outdoor air pollution was obvious, the prevalence rates of respiratory diseases were higher in the susceptible children who were influenced by the other risk factors compared with those who were not influenced by the same factors. Conclusion Outdoor air pollution is an important factor which will damage children's respiratory system in Anshan city.
