Objective: To explore the clinical characteristics, common pathogens in children with vulvovaginitis. Methods: This was a retrospective cases study. A total of 3 268 children with vulvovaginitis were enrolled, who visited the Department of Pediatric and Adolescent Gynecology, Children's Hospital, Zhejiang University School of Medicine from January 2009 to December 2019. Patients were divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Patients were also divided in to 4 groups according to the season of first visit. The pathogen distribution characteristics of infective vulvovaginitis were compared between the groups. Their clinical data were collected and then analyzed by χ² test. Results: The were 3 268 girls aged (6.2±2.5) years. There were 1 728 cases (52.9%) aged <7 years, 875 cases (26.8%) aged 7-<10 years, and 665 cases (20.3%) aged 10-18 years. Of these cases, 2 253 cases (68.9%) were bacterial vulvovaginitis, 715 cases (21.9%) were fungal vulvovaginitis and 300 cases (9.2%) were vulvovaginitis infected with other pathogens. Bacterial culture of vaginal secretions was performed in 2 287 cases, and 2 287 strains (70.0%) of pathogens were detected, of which the top 5 pathogens were Streptococcus pyogenes (745 strains, 32.6%), Haemophilus influenzae (717 strains, 31.4%), Escherichia coli (292 strains, 12.8%), Staphylococcus aureus (222 strains, 9.7%) and Klebsiella pneumoniae (67 strains, 2.9%). Regarding different age groups, H.influenzae was the most common in children under 7 years of age (40.3%, 509/1 263), S.pyogenes (41.9%, 356/849) was predominantly in children aged 7 to 10 years, and E.coli was predominant in children aged 10 to 18 years (26.3%, 46/175). Susceptibility results showed that S.pyogenes was susceptible to penicillin G (610/610, 100.0%), ceftriaxone (525/525, 100.0%), and vancomycin (610/610, 100.0%); the resistance rates to erythromycin and clindamycin were 91.9% (501/545)and 90.7% (495/546), respectively. For H.influenzae, 32.5% (161/496) produced β-elactamase, and all strains were sensitive to meropenem (489/489, 100.0%) and levofloxacin (388/388, 100.0%), while 40.5% (202/499) were resistant to ampicillin. Among E.coli, all strains were sensitive to imipenem(100%, 175/175). The resistance rates of E.coli to levofloxacin and ceftriaxone were 29.1% (43/148) and 35.1% (59/168), respectively. A total of 48 strains of methicillin-resistant Staphylococcus aureus (MRSA) were isolated with a proportion of 28.3% (45/159) in 3 268 patients. The results of drug susceptibility test showed that all MRSA strains were sensitive to linezolid 100.0% (40/40), vancomycin (45/45, 100.0%), and tigecycline (36/36, 100.0%); the resistance rates of MRSA to penicillin G, erythromycin and clindamycin were 100% (45/45), 95.6% (43/45) and 88.9% (40/45), respectively. All methicillin-sensitive Staphylococcus aureus (MSSA) strains were sensitive to oxacillin (114/114, 100.0%), linezolid (94/94, 100.0%), vancomycin (114/114, 100.0%), and tigecycline (84/84, 100.0%); it's resistance rates to penicillin G, erythromycin and clindamycin were 78.1% (89/114), 59.7% (68/114) and 46.5% (53/114), respectively. The drug resistance rate of MSSA to penicillin G, erythromycin and clindamycin were lower than those of MRSA (χ²=11.71,19.74,23.95, respectively, all P<0.001). Conclusions: The age of consultation for pediatric infectious vulvovaginitis is mainly around 6 years. The most common pathogens are S.pyogenes, H.influenzae and Escherichia coli. Third generation cephalosporins can be used as the first choice of empirical anti-infection drugs. However, the results of drug susceptibility should be considered for targeted treatment.

OBJECTIVE: To analyze the distribution and drug resistance of pathogens in oral mucositis associated with chemotherapy in hospitalized patients with malignant hematopathy, so as to provide scientific evidences for rational selection of antibiotics and infection prevention and control. METHODS: From July 2020 to June 2022, 167 patients with malignant hematopathy were treated with chemical drugs in the Department of Hematology, Hainan Hospital, and secretions from oral mucosal infected wounds were collected. VITEK2 COMPECT automatic microbial identification system (BioMerieux, France) and bacterial susceptibility card (BioMerieux) were used for bacterial identification and drug susceptibility tests. RESULTS: A total of 352 strains of pathogens were isolated from 167 patients, among which 220 strains of Gram-positive bacteria, 118 strains of Gram-negative bacteria and 14 strains of fungi, accounted for 62.50%, 33.52% and 3.98%, respectively. The Gram-positive bacteria was mainly Staphylococcus and Streptococcus, while Gram-negative bacteria was mainly Klebsiella and Proteus. The resistance of main Gram-positive bacteria to vancomycin, ciprofloxacin and gentamicin was low, and the resistance to penicillin, cefuroxime, ampicillin, cefotaxime, erythromycin and levofloxacin was high. The main Gram-negative bacteria had low resistance to gentamicin, imipenem and penicillin, but high resistance to levofloxacin, cefotaxime, cefuroxime, ampicillin and vancomycin. The clinical data of oral mucositis patients with oral ulcer (severe) and without oral ulcer (mild) were compared, and it was found that there were statistically significant differences in poor oral hygiene, diabetes, sleep duration less than 8 hours per night between two groups (P<0.05). CONCLUSION Gram-positive bacteria is the main pathogen of oral mucositis in patients with malignant hematopathy after chemotherapy. It is sensitive to glycopeptide antibiotics and aminoglycosides antibiotics. Poor oral hygiene, diabetes and sleep duration less than 8 hours per night are risk factors for oral mucositis with oral ulcer (severe).

To investigate the effect of Fuyanshu Capsules combined with Western medicine antibiotics on symptoms and inflammatory factors IL-10 and IL-1β in patients with pelvic inflammatory disease and its possible mechanism. Totally 112 patients with pelvic inflammatory disease of damp-heat stagnation treated since April 2017 to April 2018 were randomly divided into treatment group( group A,57 cases) and control group( group B,55 cases). The treatment group was given Fuyanshu Capsules for 56 d,and levofloxacin hydrochloride tablets and metronidazole tablets for 14 d. The control group was given Fuyanshu Capsules as its analogue. The curative rate,effective rate and inefficiency,serum IL-10 and IL-1β levels were compared between the two groups. The curative effect was evaluated with McCormack score and traditional Chinese medicine( TCM) syndrome score. The recurrence rate and chronic pelvic pain were followed up after one menstrual cycle. It was found that the curative rate and effective rate of group A were higher than those of group B after treatment. After 28 d of treatment,there was a difference in the effective rate of TCM syndrome score between group A and group B( 62. 71% vs 8. 47%,P < 0. 01). After 56 d of treatment,serum IL-10 increased,while IL-1β decreased in group A,which was significantly different from that in group B( P<0. 01). The recurrence rate of PID and chronic pelvic pain in group A were significantly lower than those in group B( P<0. 01). The results showed that Fuyanshu Capsules combined with levofloxacin and metronidazole could alleviate the clinical symptoms and signs of chronic pelvic inflammation of damp-heat stagnation type,reduce the recurrence rate of pelvic inflammation,relieve pelvic pain,and alleviate the inflammation status of patients by regulating the expression of IL-10 and IL-1β in peripheral serum.

ObjectiveTo evaluate the effect of cefoxitin prophylactic in reducing the incidence of severe infection after transrectal prostate biopsy (TRPB).

METHODSThis retrospective study included 155 cases of TRPB with a 5-day administration of oral levofloxacin at 200 mg bid (the control group) and another 167 cases with a 3-day administration of oral levofloxacin at the same dose plus intravenous cefoxitin at 2.0 g 2 hours before TRPB (the experimental group) according to the distribution characteristics of drug-resistance bacteria in our department. The patients of the control and experimental groups were aged (68.68 ± 8.12) and (68.72 ± 7.51) years, with PSA levels of (19.78 ± 21.57) and (21.15 ± 42.63) μg/L, involving (11.68 ± 1.44) and (11.77±1.02) biopsy cores, respectively. Comparisons were made between the two groups of patients in the incidence rate of severe infection, which was defined as lower urinary track symptoms plus the systemic inflammatory response syndrome (SIRS) within 7 days after TRPB.

RESULTSThe incidence rate of postoperative severe infection was significantly lower in the experimental group than in the control (0.6% ［1/167］ vs 5.8% ［9/155］, P < 0.05). Blood cultures revealed positive E-coli strains in 6 cases in the control group, including 5 ESBL-positive and 4 quinolone-resistant and amikacin-sensitive cases, all sensitive to cefoxitin, cefoperazone/sulbactam and imipenem. The only one case of severe infection was shown to be negative in blood culture.

CONCLUSIONSPreoperative intravenous administration of cefoxitin according to the specific distribution characteristics of drug-resistance bacteria can significantly reduce the incidence of severe infection after TRPB.

Objective: To investigate the short- and long-term effects of triple acupuncture at the Qugu acupoint as an adjunctive therapy on type-Ⅲ chronic prostatitis / chronic pelvic pain syndrome (CP/CPPS). METHODS: We equally randomized 90 CP/CPPS patients into a control and a treatment group, both treated with Levofloxacin Mesylate Tablets (0.5 g, tid) + Terazosin Hydrochloride Capsules (2 mg qd) for 4 weeks, while the latter group by triple acupuncture at the Qugu acupoint as an adjunctive therapy twice a week at the same time. Then, we followed up all the patients for 4 weeks, recorded the cases, time and rate of recurrence, obtained the scores in National Institutes of Health Chronic Prostatitis Symptom Index (NIH-CPSI), quality of life (QoL) and Zung Depression Scale (ZDS), and compared them between the two groups of patients. RESULTS: Compared with the controls, the patients of the treatment group showed significantly decreased NIH-CPSI scores in pain (8.6 ± 2.12 vs 6.2 ± 2.25, P <0.05), micturition (5.8 ± 1.22 vs 3.1 ± 1.10, P <0.05), and QoL (6.0 ± 1.33 vs 3.4 ± 1.71, P <0.05) and ZDS score as well (43.9 ± 4.53 vs 33.6 ± 3.20, P <0.01). The recurrence rate was markedly lower while the recurrence time remarkably longer in the treatment than in the control group (15.56 vs 35.56% and ［20.0 ± 2.72］ vs ［12.5 ± 3.47］ d, P <0.05). CONCLUSIONS As an adjunctive therapy, triple acupuncture at the Qugu acupoint can evidently ameliorate the clinical symptoms, enhance the curative effect of antibacterials, reduce the recurrence rate, and prolong the recurrence time in the treatment of CP/CPPS.

This research was aimed to find the skin irritation and burns treatment effect of wound dressing with mi- crospheres containing levofloxacin. We used reference GB/T16886. 10-2005 to evaluate the dressing skin irritation. We prepared rabbit models divided into three groups. The control group was rapped with Vaseline gauze bandage, while the positive control group was rapped with the wounds of nano-silver paste bandage. The experimental sample group was rapped with wound dressing with microspheres containing levofloxacin. We measured the wound without healing area and the hydroxyproline content at the ends of 3 d, 6 d, 9 d, 14 d, 21 d, 28 d. and meanwhile performed histopathological examination. The experimental results showed that the dressing primary irritation index was 0. The nonhealing wound area of theexperimental sample group and positive control group at the ends of 6 d, 9 d, 14 d, 21 d were less than that of the control group (P<0. 05). The nonhealing wound area of the experimental sample group at the ends of 9 d and 14 d was significantly lower than that of the positive control group (P < 0.05). The hydroxyproline content of the experimental sample group at the ends of 6 d, 9 d and 14 d was significantly higher than that of the positive control group and blank control group (P<0. 05). The pathology observed of the experimental sample group at 21 d were the earliest appendages. The wound dressing with microspheres containing levofloxacin has minimal skin irritation, effectively promote wound healing of burn.

PURPOSE: Fluoroquinolones, rapidly gaining prominence in treatment of Stenotrophomonas maltophilia (SMP), are noted for their potency and tolerability. However, SMP may rapidly acquire resistance to fluoroquinolones. We evaluated associations of clinical factors with acquisition of levofloxacin resistance (LFr) in SMP. MATERIALS AND METHODS: Our retrospective cohort study was based on patient data collected between January 2008 and June 2010. Through screening of 1275 patients, we identified 122 patients with data for SMP antibiotic susceptibility testing in > or =3 serial SMP isolates. RESULTS: We assigned the 122 patients to either the SS group (n=54) in which levofloxacin susceptibility was maintained or the SR group (n=31) in which susceptible SMP acquired resistance. In multivariate regression analysis, exposure to levofloxacin for more than 3 weeks [odds ratio (OR) 15.39, 95% confidential interval (CI) 3.08-76.93, p=0.001] and co-infection or co-colonization with Klebsiella pneumoniae resistant to levofloxacin (OR 4.85, 95% CI 1.16-20.24, p=0.030) were independently associated with LFr acquisition in SMP. CONCLUSION: Acquisition of LFr during serial sampling of SMP was related to the levofloxacin exposure.
