A 40-year-old, gravida 3 para 2 (1-1-0-2), previous primary cesarean section for nonreassuring fetal status, presented at a tertiary hospital for confirmation of cesarean scar pregnancy (CSP). Transvaginal ultrasound confirmed a CSP at 8 2/7 weeks age of gestation with good embryonic cardiac activity, raising concern for early placenta accreta spectrum. A multidisciplinary team composed of an obstetrician, advanced pelvic surgeon, urologist, and anesthesiologist managed the patient. The patient underwent total abdominal hysterectomy with bilateral salpingectomy, as the patient has a completed family size. Before the procedure, she was given cefuroxime as prophylactic antibiotic. Intraoperatively, there were dense adhesions between the posterior bladder wall and the previous cesarean section scar. Inadvertent injury to the bladder wall was incurred during adhesiolysis. Cystorrhaphy was done by a urologist, while the rest of the surgery was unremarkable, with a 450 ml estimated blood loss. The postoperative course was unremarkable. Bladder rest was achieved by maintaining an indwelling Foley catheter, which remained in place upon discharge on postoperative day 3 and was continued for 7 days thereafter. At follow-up, a successful voiding trial was conducted, confirming the return of normal bladder function.

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).

Introduction: Chronic bullous disease of childhood (CBDC) is a rare immune-mediated subepidermal vesiculobullous eruption, characterized by linear IgA deposition along the basement membrane zone of the skin. Although mostly idiopathic, CBDC may be triggered by factors such as infection, and drugs. Clinical and immunohistopathological features of drug-induced cases are heterogeneous and indistinguishable from the idiopathic form. Case report: A two-year-old Filipino male presented with pruritic vesicles and bullae on the back several days after finishing a course of cefuroxime, and cefaclor. Examination revealed multiple tense vesicles and bullae, some coalescing into a rosette pattern with central crusts on the perioral, scalp, neck, back, perineal, and perianal areas. Histopathology showed a subepidermal split with neutrophilic and eosinophilic infiltrates. Direct immunofluorescence revealed strong linear deposition of IgA, and granular deposits of C3 and IgM at the basement membrane zone, thus confirming the di- agnosis of CBDC. Dapsone at 2mg/kg/day was started, with oral prednisolone (1.3mg/kg/day), and cloxacillin syrup (40mg/kg/day). Topical care with betamethasone dipropionate and mupirocin ointment was included. After eight weeks, patient showed significant im- provement with few vesicles and resolved lesions healing with post-inflammatory hyperpigmentation. Conclusion We report a case of a two-year-old male presenting with vesiculobullous lesions after a course of cefuroxime, and cefaclor. As both were given and withdrawn in a period of close proximity, it is difficult to determine the probable culprit drug. Spontaneous resolution upon withdrawal of the suspected drug is variable. Systemic therapy such as dapsone may be necessary for treatment.

In this study, we explored the antibacterial effect and mechanism of dihydroartemisinin(DHA) combined with cefuroxime(CFX) or ampicillin against Escherichia coli. The minimum inhibitory concentration(MIC) of DHA, cefuroxime, and ampicillin against E. coli was 300,25,25 μmol·L~(-1), respectively, determined by broth microdilution method and 2,3,5-triphenyltetrazolium chloride(TTC) method. The minimum bactericidal concentration(MBC) was 25 μmol·L~(-1) for cefuroxime, above 600 μmol·L~(-1) for DHA. The fractional inhibitory concentration index(FICI) of DHA combined with cefuroxime or ampicillin was 0.375 and 0.75, respectively, determined by checkerboard microdilution assay, suggesting the synergistic effect or additive effect of the drug combination. Moreover, the time-effect curve showed that the antibacterial activity of DHA and CFX combination was much stronger than that of either of the drugs, suggesting that combination with DHA can decrease the CFX dosage. Then we studied the synergistic mechanism of DHA combined with cefuroxime and found that the combination of the two drugs had a significant inhibitory effect on the total protein bands, as shown by the results of polypropylene gel electrophoresis. The results of conductivity method and alkaline phosphatase test respectively showed that its conductivity value and alkaline phosphatase(AKP) leak were significantly higher than either of the drugs, suggesting that the integrity of bacteria may be damaged. The scanning electron microscope(SEM) results showed that the morphology of E. coli was destroyed most in the combination group. The quantitative fluorescence PCR technology showed that the combination of two drugs can inhibit the expression of superoxide stress gene soxS. In summary, the combination of dihydroartemisinin and cefuroxime has a synergistic antibacterial effect on E. coli.

BACKGROUND/AIMS: Efforts to decrease the use of extended-spectrum cephalosporins are required to prevent the selection and transmission of multi-drug resistant pathogens, such as extended-spectrum beta-lactamase (ESBL)-producing Enterobacteriaceae. The objectives of this study were to assess the clinical efficacy of intravenous cefuroxime as an empirical antibiotic for the treatment of hospitalized women with acute pyelonephritis (APN) caused by Escherichia coli. METHODS: We analyzed the clinical and microbiologic database of 328 hospitalized women with community-onset APN. RESULTS: Of 328 women with APN, 22 patients had cefuroxime-resistant E. coli APN, and 306 patients had cefuroxime-susceptible E. coli APN. The early clinical success rates were significantly higher (p = 0.001) in the cefuroxime-susceptible group (90.8%, 278/306) than in the cefuroxime-resistant group (68.2%, 15/22) at 72 hours. The clinical cure rates at 4 to 14 days after completing antimicrobial therapy were not significantly different in the cefuroxime-resistant or -susceptible groups, with 88.2% (15/17) and 97.8% (223/228; p = 0.078), respectively. The microbiological cure rates were not significantly different and were 90.9% (10/11) and 93.4% (128/137), respectively (p =0.550). The median duration of hospitalization in the cefuroxime-resistant and -susceptible groups was 10 days (interquartile range [IQR], 8 to 13) and 10 days (IQR, 8 to 14), respectively (p =0.319). CONCLUSIONS: Cefuroxime, a second-generation cephalosporin, can be used for the initial empirical therapy of community-onset APN if tailored according to uropathogen identification and susceptibility results, especially in areas where the prevalence rate of ESBL-producing uropathogens is low.

OBJECTIVETo investigate the influence of cefuroxime sodium (CS) on the electrophysiological function of cerebellar Purkinje cells (PCs) in Sprague-Dawley rats.

METHODSPostnatal day 7 (P7) Sprague-Dawley rats were divided into early administration I and II groups (administered from P7 to P14) and late administration group (administered from P14 to P21), and all the groups received intraperitoneally injected CS. The control groups for early and late administration groups were also established and treated with intraperitoneally injected normal saline of the same volume. There were 10 rats in each group. The rats in the early administration I group and early administration control group were sacrificed on P15, and those in the early administration II group, late administration group, and late administration control group were sacrificed on P22. The whole-cell patch-clamp technique was used to record inward current and action potential of PCs on cerebellar slices, as well as the long-term depression (LTD) of excitatory postsynaptic current (EPSC) in PCs induced by low-frequency stimulation of parallel fiber (PF).

RESULTSCompared with the control groups, the early and late administration groups had a slightly higher magnitude of inward current and a slightly higher amplitude of action potential of PCs (P>0.05). All administration groups had a significantly higher degree of EPSC inhibition than the control groups (P<0.01), and the early administration II group had a significantly greater degree of EPSC inhibition than the late administration group (P<0.01).

CONCLUSIONSEarly CS exposure after birth affects the synaptic plasticity of PF-PCs in the cerebellum of young rats, which persists after drug withdrawal.

PURPOSE: This study examined the clinical effectiveness of parenteral cefuroxime and cefotaxime as empirical antibiotics for treating hospitalized women with uncomplicated acute pyelonephritis (APN). MATERIALS AND METHODS: This study was based on the clinical and microbiologic data of 255 hospitalized women with APN. Of these 255 women, 144 patients received cefuroxime and 111 received cefotaxime. RESULTS: There were no marked differences in the demographic features, clinical characteristics, and treatment duration between the populations of the cefuroxime and cefotaxime groups. The rates of defervescence showed no significant differences in the two groups at 48, 72, 96, and 120 hours. The clinical cure rates observed at the follow-up visit 4 to 14 days after the completion of antimicrobial therapy were not statistically different between the cefuroxime and cefotaxime groups [94.9% (129 of 136) versus 98.0% (100 of 102), respectively; p=0.307], and the microbiological cure rates were also not significantly different [88.3% (91 of 103) versus 95.0% (76 of 80), respectively; p=0.186]. The median hospitalization periods in the cefuroxime and cefotaxime groups were 7 (6-8) and 7 (6-8) days (p=0.157), respectively. Microbiological success rates after 72-96 hours of initial antimicrobial therapy were also not statistically different in the cefuroxime and cefotaxime groups, 89.4% (110 of 123) versus 94.9% (93 of 98; p=0.140). CONCLUSION: Cefuroxime, a second-generation cephalosporin, is an appropriate antibiotic option for the initial treatment of uncomplicated APN and its efficacy does not differ from cefotaxime, a third-generation cephalosporin, in the initial parenteral therapy for community-onset APN.

The aim of this study was to identify bacteria isolated from the oral cavities and to determine their antimicrobial susceptibility against eight antibiotics. The bacterial strains were obtained from the Korean Collection for Oral Microbiology (KCOM). The bacteria were identified by comparing 16S rDNA sequences at the species level. The data showed that 77 bacterial strains were predominantly identified as streptococci (49.4%) and staphylococci (14.3%). Minimum inhibitory concentrations (MIC) were determined using a broth dilution assay to test the sensitivity of the bacterial strains. The MIC values of the oral bacterial strains against antibiotics were different. Streptococci were sensitive to clindamycin, cefuroxime axetil, and vancomycin, and they were resistant to tetracycline. Staphylococci also were sensitive to clindamycin, cefuroxime axetil, and vancomycin, and they were resistant to penicillin antibiotics. Gram-negative bacterial strains were sensitive to tetracycline and were resistant to clindamycin. These results suggest that the antimicrobial susceptibility test is necessary in deciding the prescription for antibiotics, to prevent the misuse or abuse of antibiotics.

The purpose of this study was to isolate and identify bacteria from the 4 patients with non-odontogenic infectious lesions (mucormycosis, chronic inflammation from wound infection, and two actinomycosis) and determine their antimicrobial susceptibility against eight antibiotics. Bacterial culture was performed under three culture conditions (anaerobic, CO2, and aerobic incubator). The bacterial strains were identified by 16S rRNA gene (16S rDNA) sequence comparison analysis method. For investigating the antimicrobial susceptibility of the bacteria against eight antibiotics, penicillin G, amoxicillin, tetracycline, cefuroxime, erythromycin, clindamycin, vancomycin, and Augmentin(R) (amoxicillin + clavulanic acid), minimum inhibitory concentration (MIC) measurement was performed using broth microdilution assay. Nosocomial pathogens such as Enterococcus faecalis, Klebsiella pneumoniae, Bacillus subtilis, and Neisseria flavescens were isolated from mucormycosis. Veillonella parvula, Enterobacter hormaechei, and Acinetobacter calcoaceticus were isolated from chronic inflammatory lesion. Actinomyces massiliensis was isolated from actinomycosis in parotid gland. Capnocytophaga ochracea was isolated from actinomycosis in buccal region in anaerobic condition. There was no susceptible antibiotic to all bacteria in mucormycosis. Tetracycline was susceptible to all bacteria in chronic inflammation. C. ochracea was resistant to vancomycin and penicillin G; and other antibiotics showed susceptibility to all bacteria in actinomycosis. The results indicated that the combined treatment of two or more antibiotics is better than single antibiotic treatment in mucormycosis, and penicillin is the first recommended antibiotic to treat actinomycosis.

BACKGROUNDIntracranial infection is one of the most common complications of open craniocerebral injury and of conventional craniotomy in neurosurgery. The presence of blood-brain barrier leads to lower drug concentrations in the cerebrospinal fluid than in the venous blood. Increasing the intravenous dosage or frequency carries the risk of systemic adverse reactions or infections in other parts of the body. Developing an artificial dura mater (ADM) for sustained antibiotic release for use during neurosurgery can solve the problems perfectly.

METHODSThree types of drug-loaded ADMs made of collagen and containing cefuroxime sodium, ceftriaxone sodium, or norvancomycin were prepared. The antibacterial activity and sustained release characteristics of the ADMs were examined using bacteriostatic and release tests.

RESULTSSingle-layered collagen based ADMs (40 mm×50 mm×5 mm) containing 18 mg cefuroxime sodium or ceftriaxone sodium were not suitable for continued development because of drug preservation and stability issues. Using smaller ADMs (20 mm×30 mm×7 mm), containing 4.86 mg of norvancomycin, with increased collagen density and a three-layered film with two outer drug-free films above and below the antibiotic layer resulted in sustained cumulative release of 2.91 mg (59.9%) of norvancomycin over 72 hours. The similar factor (f2) comparison method proved that products from a same batch were statistically significant similar (f2 > 50).

CONCLUSIONSArtificial ADMs made of collagen can be processed to provide a mature dural repair material for the sustained release of norvancomycin. This system may provide a basis for developing sustained release materials for other drugs.
