Objective To investigate the pathogenic characteristics and use of antibiotics in children with acute osteomyelitis,and to provide evidence for rational drug use in the clinic.Methods The clinical data of 266 children with acute osteomyelitis admitted to the Department of Orthopedics,Children's Hospital Affiliated to Zhengzhou University from January 2019 to December 2022 were retrospectively analyzed,and the basic information,pathogenic microorganisms,drug sensitivity test results,and antibacterial drug use of the children were statistically analyzed.Results In 266 cases of pediatric acute osteomyelitis,all underwent pathogen examination,and 148 cases were cultured for pathogens with a positive detection rate of 55.64％.A total of 154 strains of bacteria were detected.The top three pathogens were Staphylococcus aureus(104 strains,67.53％),Staphylococcus epidermidis(8 strains,5.19％),and Staphylococcus hominis(7 strains,4.55％).The detection rate of methicillin-resistant Staphylococcus aureus(MRSA)was 33.65％.Compared with methicillin-sensitive Staphylococcus aureus(MSSA),there was no significant difference in disease severity and prognosis of infection with MRSA.The utilization rate of antibiotics was 100.00％;227 cases of empirical antibiotics were used alone,accounting for 85.34％,primarily using ceftriaxone.Combination therapy was used in 39 cases,accounting for 14.66％,mainly ceftriaxone combined with vancomycin;the average course of intravenous drugs was 40.20 days.After receiving the drug sensitivity test results in 148 cases,76 cases(51.35％)continued the original treatment plan due to effective treatment.In 37 cases(25.00％),treatment was adjusted based on the drug sensitivity results due to poor treatment outcomes;the drug sensitivity results indicated sensitivity,but the clinical effect was not good in 25 cases accounting for 16.89％,which changed the drug treatment.In 10 cases(6.76％),clinical treatment was effective,leading to a switch to narrow-spectrum antibiotics or a change from combination therapy to monotherapy based on drug sensitivity results.Conclusion Empiric antibacterial therapy can cover common pathogens in children with acute osteomyelitis,and medication regimens can be adjusted according to clinical efficacy and drug sensitivity.However,the course of intravenous antibiotic treatment is too long,so it is necessary to further optimize the timing of transitioning from intravenous to oral administration.

Objective To investigate the pathogen characteristics of perforated appendicitis in children and the perioperative use of antimicrobials in order to provide evidence for the rational use of perioperative antibiotics. Methods The perioperative usage of antibiotics was analyzed to determine the reasonableness of antimicrobial use in children with perforated appendicitis who were discharged from July 2011 to August 2014,based on“guidelines of clinical use of antibiotics”and results of bacterial culture. Results Inflammatory secretions obtained from 126 children(126/ 149)were sent for examination and the examination rate was 84.56%.A total of 117 cases were found positive for cultured pathogens,and the detection positive rate was 92.86%.Three types of bacteria ranking the first three places were Escherichia coli,Pseudomonas aeruginosa and CitroBacter freundii.The utilization rate of antibacterial agents was 100.00%,with a dominant use of cephalosporins and nitrate imidazoles. Rational use of antimicrobial agents was found in 144 cases(accounting for 96.64%). Conclusion The major pathogen in perforated appendicitis is still Escherichia coli,which is highly sensitive to commonly used antibiotics,and drug-sensitivity testing results can help guide the treatment programs and antibiotics selection.

OBJECTIVE:To explore the effects of enteral nutrition powder in children with phenylketonuria(PKU)under one year. METHODS:120 PKU children under one year were selected and given enteral nutrition powder(20 g/kg,qd)for consecutive 32 weeks. The level of benzene,height,weight,head circumference,IQ level,nutrition indicators and ADR were compared be-fore treatment,8 weeks after treatment,32 weeks after treatment. RESULTS:8 and 32 weeks after treatment,the level of benzene decreased gradually,and height,weight and head circumference increased gradually,with statistical significance(P0.05). 66 cases suffered from 181 times of ADR,mainly including 10 times diarrhea and 126 times upper respiratory tract infection,among which one children developed moderate gastroen-teritis. They were all recovered after symptomatic treatment. CONCLUSIONS:For PKU children under one year,enteral nutrition powder can effectively control the phenylalanine levels,prevent the decrease of IQ and improve the nutritional status so as to meet the normal growth and development of children nutritional requirements,with better safety and tolerance.

Objective:To investigate the off-label drug use in the outpatients of Zhengzhou children's hospital in 2013 to provide the evidence for improving the rational drug use in pediatrics. Methods:The prescriptions of outpatients were randomly selected from January to December in 2013. According to the drug instruction, the off-label drug uses were analyzed in the following aspects: sam-pling conditions, the kinds of off-label drug use, the incidence of off-label drug use in different age groups and drug categories. Re-sults:A total of 8 684 prescriptions with 16 344 medical records involving 410 kinds of drugs were analyzed, and the rate of off-label drug use was 70. 87% for prescription, 51. 21% for medical orders and 71. 95% for category, respectively. The primary types of off-label drug use were over applicable people (50. 83%), dosage(21. 00%) and frequency (19. 04%). The top 3 age groups with high-est off-label drug use rate were neonates (63. 27%), infants (56. 20%) and school-age (44. 98%). The top 5 drugs with highest off-label drug use rate were cardiovascular system medicines (99. 02%), anti-infective agents (64. 14%), vitamin and mineral drugs (62. 89%), hematological system medicines (59. 48%) and Chinese patent drugs (53. 43%). Conclusion: Off-label drug use in outpatients is prevalent. Physicians should master indications, usage and dosage described in instructions, select suitable dosage form, reduce off-label drug use and improve drug safety in pediatrics.

OBJECTIVE:To provide baseline data for the formulation of the strategy for medical institutions in China. METH-ODS:3 600 discharged medical records were randomly collected from our hospital in 2013. According to drug package inserts,the judgment was carried out about whether off-label drug use existed in medical orders. The types of off-label drug use,off-label drug use of children in different age groups and of various drugs were all analyzed. RESULTS:A total of 3 268 hospitalized children were includ-ed,and 35 523 medical orders were analyzed,involving 468 types. Based on children,medical orders and drug types,the incidence of off-label drug use were 91.34%,35.72%and 48.72%,respectively. The types of off-label drug use mainly included pediatric medica-tion information(74.21%), exceeding route of administration(8.12%)and overage(8.45%). The top 3 age groups with respect to the incidence of off-label drug use were adolescents(42.42%),neonate(37.97%)and infant(35.48%). Top 4 drugs of off-label use in the list of medical orders were anti-infective drugs(23.65%),electrolytic,drugs for acid-base balance and nutrition(12.21%), drugs for respiratory system(36.84%)and cardiovascular drugs(63.21%). CONCLUSIONS:The off-label drug use of hospitalized children is common in our hospital. It is urgent to develop related laws and regulations or guidelines to regulate off-label drug use in or-der to ensure the safety of pediatric drug use.
