ABSTRACT
Objective: To observe the efficacy of different anti-infective treatment regimens on acute appendicitis in children, a retrospective study was conducted by collecting previous cases. Methods: Ninety children with acute appendicitis who received laparoscopic appendectomy from May 2020 to September 2022 were included in this retrospective study. According to the different anti-infective treatment regimens, they were divided into Piperacillin-Tazobactam group, Piperacillin-Tazobactam+Metronidazole group, and Cefminox+Metronidazole group (n=30). Three groups of children received medication treatment before surgery. The postoperative recovery, treatment effect, bacterial clearance, complication rate, pharmacoeconomic evaluation, and adverse reactions were compared. Results: The effective rates in the three groups were 83.33%, 90.00%, and 90.00%, respectively (P > .05). There were no differences in the bacterial clearance, complication incidence, and incidence of pharmaceutical side effects among the three groups (P > .05). The total hospitalization cost, total drug cost, and antimicrobial drug cost in Cefminox + Metronidazole group were lower than those in Piperacillin-Tazobactam group and Piperacillin-Tazobactam + Metronidazole group, respectively (P < .05). The intensity of antibacterial drug use in Piperacillin-Tazobactam group was the lowest, followed by Piperacillin-Tazobactam + Metronidazole group and Cefminox + Metronidazole group (P < .05). Conclusion: The three anti-infective regimens have the same therapeutic effect on acute appendicitis in children. However, the regimen of Cefminox + Metronidazole is the most economical option and can be used as the preferred treatment for acute appendicitis in children. As the preferred treatment for acute appendicitis in children. The Piperacillin-Tazobactam group has the lowest intensity of antibiotic use and can reduce bacterial resistance.
ABSTRACT
BACKGROUND: About 10% latent tuberculosis infections (LTBI) would progress to active tuberculosis (TB), if left prophylactic therapy. Tuberculin skin test (TST) is the most widely used method for LTBI screening in the school of China. However, for college students, the association between TST reaction size and active TB risk was unclear. METHODS: We conducted a retrospective study to assess whether the TST reaction size would predict active TB during the next two years after TST screening for college students. Multivariable Cox regression was performed to identify the size of TST reaction and other factors associated with active TB risk. RESULTS: A total of 67292 college students in Beijing, China were included in this study; 8021 (11.92%) individuals were TST positive (≥10 mm), and 3879 (5.76%) of them were strong TST positive (≥15 mm). During the two years of follow-up, 26 active TB cases were reported in 134575 person-years with an incidence rate of 19.32 (95% CI: 12.61-28.32) per 100000 person-years. The adjusted hazard ratios (HR) (95% CI) were 1.094 (0.247~4.846), 3.644 (1.188~11.179), 6.832 (2.436~19.163) and 9.768 (2.203~43.315) of cohorts with the TST reaction size intervals 5~9, 10~14, 15~20 and ≥ 20 mm, respectively, compared to cohort with interval 0~4 mm. Besides, the adjusted HR (95% CI) was 3.593 (1.354~9.537) of males compared to females. CONCLUSIONS: This study indicated that the risk of active TB increased in college students when the TST reaction size was ≥10 mm, and males had a higher risk compared to females.
