Clinical estimation of efficiency of application of terpene-containing preparation in complex treatment of chronic generalized parodontitis

The article presents the comparative analysis of application of terpene-containing medicine Antiran (1:3 solution) and 0.06% chlorhexidine bigluconate solution in a complex therapy of patients with chronic generalized parodontitis. According to the curative effect, these drugs are comparable with antibacterial and antiseptic agents, but they act more gently and, as a rule, do not cause side effects. Currently, as a etiotropic therapy of periodontitis, a wide range of drugs affecting the parodontal pathogenic microflora, irrational use of antibacterial agents has acquired the status of a global problem of modern medicine, since it leads to the emergence of resistant strains of microorganisms that are poorly sensitive or resistant to treatment. The medicaments were used in ultrasonic scaling and for passive ultrasonic irrigation of periodontal pockets during curettage process. The results were evaluated according to the PMA, SBI, PI indexes, an extravazation time formation and periodontal pockets depth. The first total time period of clinical observation established that inflammation process was eliminated earlier when Antiran was used. Thus our study demonstrated and substantiated the successful experience of Antiran application in periodontal practice

Characterization of Pathogenic Microflora Causing Suppurative Septic Postpartum Complications: a Retrospective Cohort Study

Background. Suppurative septic postpartum complications occupy a leading position in the structure of causes of maternal mortality. Information about the characteristics of pathogenic microflora in various forms of complications and analysis of its resistance to antibacterial drugs determine the choice of rational therapy for this pathology.Objectives — to characterize the isolated pathogenic microflora in obstetric patients with suppurative septic postpartum complications.Methods. A retrospective cohort study was conducted at the Department of Obstetrics and Gynecology No. 2 of the Omsk State Medical University and the Department of Gynecology of the Omsk Regional Clinical Hospital. The study included 123 cesarean section patients treated from January 2013 to December 2022 who were divided into three groups: Group A — uncomplicated course of postpartum endometritis, n = 55; Group B — complicated forms of postpartum endometritis, n = 48: B1 — local complications (suture failure following cesarean section; parametritis) n = 29; B2 — pelvic peritonitis, n = 19; Group C — septic complications following critical obstetric conditions, n = 20. The pathogenic microflora of uterine and abdominal cavities was examined; the extent of contamination with a pathogen and sensitivity to antibacterial drugs were determined. The isolated microorganisms were identified using a MicroTax bacteriological analyzer (Austria), Vitek2 Compact (France) and routine methods; a disk diffusion method was employed to determine the sensitivity of microorganisms to antibacterial drugs. Calculations were performed using licensed Microsoft Office Excel 2013 and Statistica 10 programs (StatSoft Inc., USA). Nonparametric nominal data were compared using Pearson’s chi-squared test with p-value determination.Results. The pathogenic microflora was dominated by S. epidermidis, E. faecalis, E. coli, and E. faecium. In 2018–2022, a statistically significant decrease was observed in the isolation rate of S. epidermidis (p = 0.016), E. faecalis (p < 0.001), and E. faecium (p = 0.05). The highest resistance was exhibited by bacteria to the following antibiotics: S. epidermidis — cephalosporins (30.16%); E. faecalis — fluoroquinolones (33.33%); E. coli — cephalosporins (65.91%) and β-lactamase-resistant penicillins (40.91%); E. faecium — aminopenicillins (64.10%) and fluoroquinolones (50.0%); А. baumannii — fluoroquinolones, cephalosporins, carbapenems (100%), and aminoglycosides (84.2%). A contamination assessment revealed a high titer of isolated microorganisms in 60.53% of cases. We found a statistically significantly higher isolation rate of S. еpidermidis (p < 0.001), E. faecium (p = 0.01), and A. baumannii (p = 0.02) in the setting of pelvic peritonitis as compared to uncomplicated endometritis. In the case of suppurative septic complications due to critical obstetric conditions, the isolation rate was higher for S. еpidermidis (p <0.001), E. coli (p = 0.04), E. faecium (p = 0.005), A. baumannii (р<0.001), and K. рneumoniae (p = 0.04).Conclusion. The antibiotic resistance of pathogenic microorganisms calls for the development of new organ system support technologies and the use of methods capable of sorbing microorganisms and their toxins in the area of inflammation
