ABSTRACT

AIM: To evaluate clinical efficacy and safety of ultrasound cycloplasty(UCP)in the treatment of refractory glaucoma.METHODS:From June 2021 to October 2022, a total of 17 patients(17 eyes)with refractory glaucoma were enrolled in this prospective study, and they all underwent UCP. The patients underwent 6 mo followed-up post-treatment, and the intraocular pressure(IOP), pain grade score, IOP lowering drugs, success rate and occurrence of complications were documented.RESULTS:The IOP was significantly decreased from 51.98±7.80 mmHg before UCP to 32.54±13.21 mmHg at 1 d, 22.38±11.98 mmHg at 1 wk, 22.63±10.78 mmHg at 1 mo, 26.05±9.17 mmHg at 3 mo, and 23.73±9.60 mmHg at 6 mo postoperatively(all P<0.01). The percentage of IOP reduction after treatment was 36.25%, 57.10%, 56.35%, 49.16% and 54.09% at 1 d, 1 wk, 1, 3, and 6 mo, respectively. The pain grade scores were decreased(P<0.01). There was a statistically significant reduction in the use of IOP lowering medications(P=0.008). At 6 mo postoperatively, 2 eyes(12%)were complete success, 11 eyes(65%)were qualified success, and 4 eyes(24%)were failure. The main complication observed was anterior chamber inflammation in 1 eye(6%), foreign body sensation in 2 eyes(12%), subconjunctival hemorrhage in 2 eyes(12%), and conjunctival congestion in 6 eyes(35%). All symptoms spontaneously resolved within 1 wk without requiring any specific treatment. One case of choroidal detachment(6%)occurred on 10 d postoperatively, but recovered after orally treated by prednisone acetate for 1 mo. No other serious complications, such as hyphema, corectopia, synechia or macular edema were reported.CONCLUSION:UCP is safe and efficacious in treating refractory glaucoma, reducing IOP and alleviating ocular pain symptoms, while maintaining a favorable safety profile.

ABSTRACT

In recent years , with the increasing of immunocompromised patients , Trichosporon spp. has become a more and more significant clinical opportunistic pathogen .Medical staff should enhance the clinical awareness to this pathogen . In this paper , the classification , virulence factor and pathogenic mechanism, infections, diagnostic methods of laboratory , antifungal susceptibility and treatment of Trichosporon spp. were reviewed systematically . Trichosporon asahii is the major pathogen of invasive infections.Biofilm formation and enzyme production will promote its ability to escape from antifungal drugs and host immune responses .Matrix assisted laser desorption ionization time of flight mass spectrometry has the advantages of accurate , fast and low cost for identification of Trichosporon spp., and zoles is the first-line treatment for invasive infections .

ABSTRACT

Objective To investigate the in vitro antibacterial activity of single cefoperazone,ceftazidime,imipenem,tigecycline and colistin and their combination with sulbactam against clinical isolates of Acinetobacter baumannii (A.baumannii).Methods Twentythree meropenem-resistant A.baumannii strains and 21 meropenem-sensitive strains from the Study for Monitoring Antimicrobial Resistance Trends (SMART) during 2011 and 2012 were collected,and their combination susceptibility tests were performed by the checkerboard dilution method.The fractional inhibitory concentration (FIC) index was calculated to evaluate the combination effect of antibiotics.Results No antagonism effect was observed for all of combinations.The combination of sulbactam with cefoperazone or tigecycline mainly produced synergistic effect on A.baumannii,and the strains with FIC index ≤0.5 accounted for 56.8% and 50.0%,respectively.The combination of sulbactam with imipenem or colistin showed synergistic or partially synergistic effect on A.baumannii,and the strains with FIC index < 1 accounted for 61.4% and 52.3%,respectively.However,the combination of sulbactan with ceftazidime didn't show any interation,and the strains with FIC index ≥4 accounted for 63.6%.Conclusion The combination of sulbactam with cefoperazone has the best synergistic effect on A.baumannii,especially on carbapenem-sensitive A.baumannii.The combination of sulbactam with imipenem or tigecycline may enhance the antibacterial activity on carbapenem-resistant A.baumannii.The combination of sulbactam with imipenem or tigecycline may be helpful for the treatment of carbapenem-resistant A.baumannii infection.

ABSTRACT

Background Trachoma is a serious blinding eye disease.At present,the incidence rate of trachoma in China has been greatly reduced with the unremitting efforts of World Health Orgnization (WHO) and Chinese government.However,in some economically underdeveloped areas,there is still active trachoma.Ohjective This study aimed to survey the prevalence of children's active trachoma in rural area of Naxi district and Jiangyang district of Luzhou city and assess the prevention and treatment outcome of trachoma during 10 years.Methods A cross-sectional study was performed in Naxi district and Jiangyang district of Luzhou city,the economic underdeveloping and water-starved regions in the year 2000.The active trachoma was screened in 214 school-age children with the male 113 and female 101 based on simplified trachoma grading system and trachoma rapid assessment survey standards and requirements of WHO.The symptoms of active trachoma were divided into trachomatous follicular (TF),trachomatous inflammation intense (TI),trachomatous scarring (TS),trachoma trichiasis (TT) and corneal opacities (CO).The epidemiological survey was re-assessed in 100 school-age children (with the male 58 and female 42) in these regions in the year 2013 to evaluate the prevalence change of children active trachoma during 10 years.Results In the year 2000,214 children were screened in 4 villages of Naxi district and Jiangyang district,and the prevalence rate of TF was 49.07% (105/214) in the year 2000.The prevalence rate of TF was 49.05% (52/106) in the Naxi district and 49.07% (53/108) in the Jiangyang district,showing no significant difference between them (x2 =0.01,P =0.99).In the 100 school-age children who received survey in Naxi district and Jiangyang district in the year 2013,no TF,TF,TI,TS,TT and CO was found,showing no active trachoma.Conclusions The active trachoma has been controlled in rural areas of Luzhou city following the prevention and treatment of trachoma and the improvement of economic status in past decade.

ABSTRACT

Whole-genome sequencing of bacteria has recently emerged as a cost-effective and convenient approach for resolving many microbiological questions.Here, the current status of whole-genome sequencing in clinical microbiology and the main problems that exist were reviewed, focusing on six essential tasks: identifying and culturing the species of an isolate, rapid identification of pathogen properties, monitoring the emergence and spread of an epidemic outbreak, developing vaccine and monitoring its variation,metagenomics and single-cell sequencing.The authors predicted that the application of whole-genome sequencing will soon be sufficiently fast, accurate and cheap to be used in routine etiological detection, even though there is still a long way to go.
