Effects of diquafosol sodium in povidone iodine-induced dry eye model

AIM:To investigate the effects of diquafosol sodium(DQS)for dry eye model induced with povidone-iodine(PI)solution.METHODS:Ten Sprague Dawley rats as the control group.Thirty Sprague Dawley rats were used to establish the dry eye model with stimulation of 10 g/L PI for 14d,then divided rats into three groups:dry eye group with no treatment(DED group,n=10);phosphate buffer saline treated group(PBS group,n=10);diquafosol treated group(DQS group,n=10).Clinical changes were observed by tear production test,fluorescein staining,tear breakup time(TBUT)test,corneal confocal microscope and ocular surface comprehensive analyzer.Eyeballs were collected on day 10 of treatment for hematoxylin-eosin(HE),periodic acid-Schiff(PAS),and alcian blue staining.TUNEL assay,polymorphonuclear(PMN)and mucin 1(MUC1)immunofluorescence were performed and corneal ultrastructural changes were detected by electron microscopy.RESULTS:Compared with DED and PBS groups,tear production(7.26±0.440 vs 4.07±0.474 mm;7.26±0.440 vs 3.74±0.280 mm;all P<0.01)and TBUT(7.37±0.383s vs 1.49±0.260s;7.37±0.383s vs 1.42±0.437s;all P<0.01)were significantly increased in DQS group.HE,PAS,and alcian blue staining and MUC1 immunofluorescence showed mucins and conjunctival goblet cells density(8.45±0.718 vs 5.21±0.813 cells/0.1 mm^(2);8.45±0.718 vs 5.36±0.615 cells/0.1 mm^(2);all P<0.01)increased in DQS group.Confocal microscopy,PMN immunofluorescence and TUNEL staining showed inflammatory infiltration and corneal epithelial cells apoptosis decreased in DQS group.The increased number of microvilli in corneal epithelial and the recovered cell junction were observed in DQS group.CONCLUSION:PI instillation can induce goblet cells and mucin loss,epithelial cell apoptosis and inflammation,which are consistent with the pathological manifestations of dry eye.Diquafosol can repair the ocular surface damage caused by PI,reduce corneal inflammation,inhibit corneal epithelial cell apoptosis,promote mucin secretion and maintain tear film stability.

Is the Prophylactic Administration of Povidone Iodine Intranasally Preoperatively in Elective Total Knee Replacement as Effective as MRSA Prophylactic Screening and Mupirocin Treatment?—A Retrospective Analysis

Surgical Site Infections (SSIs) remain a prevalent issue in healthcare. An average of 2% to 4% of all Total Knee Arthroplasties (TKA/TKR) result in a Prosthetic Joint Infection (PJI) (Ashraf et al. , 2018). These surgical site infections cause significant distress to the patient and require extended courses of antibiotic treatment and revision surgery of the infected joint. SSIs also reduce financial reimbursement to the surgery facility and affect the performing surgeon’s performance scores. To prevent surgical infection, healthcare facilities have implemented various screening or decolonization methods to prevent surgical infection to may cause infection. Various treatment methods exist for managing MRSA preoperatively which include Povidone Iodine (PI) application as a universal decolonization method and/or screening every patient pre-operatively for MRSA and treating MRSA-positive patients with Mupirocin ointment. Both interventions are well-established in the literature. At the author’s facility, the elective TKR populations were analyzed while each intervention was implemented. In 2019 TKR patients underwent MRSA swabbing and testing and in 2021 PI decolonization was the decolonization method of choice. The study revealed that MRSA testing and swabbing were better at reducing SSI related to MRSA than Povidone Iodine decolonization.

Ototoxicity of povidone-iodine——A case report

Objective: The ototoxicity of povidone-iodine has been documented in animal studies. However, there is limited evidence of these ototoxic effects in humans. This is the first report to show the ototoxic effects of povidoneiodine in a human subject.Patient: A 36-year-old woman came to our hospital complaining of left unilateral persistent hearing loss. One month before presentation, her child had accidentally struck her on her left ear. She applied approximately three drops of povidone-iodine(10% weight/volume) into her left auditory canal. Immediately after application, she felt severe pain and vertigo. An audiogram revealed severe left unilateral sensorineural hearing loss. Magnetic resonance imaging showed mild enhancement of the left vestibule and basal turn of the left cochlea.Conclusions: Even a single application of povidone-iodine could cause significant hearing loss and disequilibrium. It should, therefore, be used with caution.

The Antiseptic Efficacy of Povidone-Iodine in Reducing Early Surgical Site Infections in Orthopaedic Implant Surgeries

Background: Surgical site infection (SSI) is a dreaded nightmare for the Orthopaedic surgeon. Preoperative skin cleaning with antiseptics has been shown to reduce the microbial burden of the skin and results in reduced incidence of SSI. However, the ideal skin cleaning agent remains to be established. Aim: To compare the efficacy of Povidone-Iodine/Povidone-Iodine (PI-PI) combination with that of Chlorhexidine-Gluconate/Alcohol (CG-A) combination in re-ducing SSI in Orthopaedic surgeries. Methods: This was a prospective, randomized, double-blinded, controlled study. Subjects that met the selection criteria and gave consent were randomized into PI-PI group (test group) and the CG-A group (control group). Both the patients and the assessors for SSI were blinded to the group a participant belongs. Blocking was done on the type of surgery to cancel the confounding effect of surgery type on SSI. Standard perioperative protocols were applied to both groups. Assessment for features of SSI was done on the 3rd day, 7th day, 14th day, 6th week and 12th-week postoperative period. The diagnosis of SSI was made based on the Centers for Disease and Control (CDC) guidelines. Results: We recruited 124 patients for this study, 62 males and 54 females. The mean age of the subjects was 37.5 years (SD = 14.7 years). Sixty-two subjects were randomized into each group. There was no significant difference in the distribution of the genders in the study arms. Other possible confounders such as duration of hospital stay, use of drains, the surgeon involved and age were evenly distributed in the two groups. Eight patients did not complete the study. The overall incidence of SSI in the study was 2.6%. Subjects in the control group had an SSI of 3.4% while those in the PI-PI group had a rate of 1.8%;however, this was not significant, p = 0.579. Conclusion: Both CG-A and PI-PI combinations are equally efficacious as preoperative skin antiseptic in Orthopaedic implant surgeries.

Effects of Povidone-Iodine or Ethanol Exposure on Bone Formation at the Osteotomy Site of the Proximal Tibia in Rats

Background: Povidone-iodine (PVI) irrigation is currently used to decrease the frequency of postoperative surgical site infections. Ethanol (EtOH) is sometimes applied to prevent local recurrence after curettage of benign bone tumors. However, the effects of PVI and EtOH on surrounding soft tissue and on bone union are unclear. The purpose of this study was to determine whether PVI or EtOH adversely affects the cancellous bone healing of the osteotomy site at the proximal tibia in rats. Methods: A cancellous bone osteotomy was performed at the right proximal tibia in 4-month-old, female, Sprague Dawley rats. Vehicle, 10% PVI, or 95% EtOH-soaked gauze was inserted into the osteotomy site and maintained for 6 minutes. The rats were euthanized 2 or 4 weeks after the osteotomy. Results: Two weeks after treatment, the bone union rate was significantly higher in the vehicle group than in the PVI group and the EtOH group (p < 0.001). However, the bone union rate was not significantly different between the PVI and EtOH groups. There was no significant difference among the three groups in the bone union rate 4 weeks after treatment. Conclusion: PVI or EtOH delayed bone union of the cancellous bone osteotomy site of the proximal tibia in the early phase (2 weeks), but not at 4 weeks, in rats.

Effect of diluted povidone iodine in adenoviral keratoconjunctivitis on the rate of subepithelial corneal infiltrates

AIM: To evaluate the clinical characteristics of adenoviral keratoconjunctivitis, the management modalities, as well as the incidence of subepithelial corneal infiltrates(SEI).METHODS: Patients with characteristic clinical symptoms and signs, who presented to our clinic within the first week of symptoms and received the diagnosis of adenoviral keratoconjunctivitis between January 2013 and April 2016, were included in the study. A total of 211 patients were included in the study. Patients were evaluated for the incidence of clinical signs, late complications, management preferences, and the effect of diluted povidone-iodine(d-PVP-I) 2%. RESULTS: Patients’ mean age was 33.03±14.76 y. We observed an increase in the number of cases according to the years. At presentation and/or early follow-up, the clinical signs were conjunctival hyperemia(100%), conjunctival follicules(79.1%), edema of the eyelids(39.3%), chemosis(16.1%), pseudomembrane formation(16.6%), and corneal epitheliopathy(29.9%). During late follow-up 13.3% patients developed conjunctival subepithelial fibrosis, and 39.8% developed SEI. A significant decrease in the incidence of SEI development was observed in patients who used d-PVP-I 2%(P=0.032;33.3% vs 45.9%, respectively in patients who received d-PVP-I 2% and who did not).CONCLUSION: Adenoviral keratoconjunctivitis has a tremendous effect on patient’s comfort and abilities in short-term. Additionally, almost half of the patients develop visual problems related to SEI. According to our clinical experience, using d-PVP-I 2% in the first days of adenoviral keratoconjunctivitis might be helpful in reducing the risk of SEI as a complication.

【目的】负载多功能纳米硒聚维酮碘(PVP-I@Se)消毒剂对金黄色葡萄球菌(SA)、耐甲氧西林金黄色葡萄球菌(MRSA)的杀菌效果,为皮肤手术部位消毒提供实验依据。【方法】实验分为PVP-I组(对照组)与PVPI@Se组(实验组),两组的碘浓度梯度相同,分别为50、75、100、200和400μg/mL,实验组硒浓度2μg/mL,对照组不添加硒,比较两组不同的消毒液对SA、MRSA的消毒效果,检测指标包括最低抑菌浓度(MIC)和最低杀菌浓度(MBC);碘浓度50μg/mL时的最短杀菌时间;碘浓度200μg/mL、400μg/mL时的抑菌圈大小。【结果】对照组对SA、MRSA的MIC均为79.17μg/mL、实验组分别为54.17和70.83μg/mL。而对照组对SA、MRSA的MBC分别为129.17和150.00μg/mL,实验组分别为70.83和87.50μg/mL。碘浓度50μg/mL时,对照组对SA、MRSA的最短杀菌时间为130 s、140 s,实验组分别为65 s、75 s。碘浓度200μg/mL时,对照组对SA、MRSA的抑菌圈直径分别为7.67 mm、8.33 mm,实验组均为9.50 mm。碘浓度400μg/mL时,对照组对SA、MRSA的抑菌圈直径分别为9.00 mm、9.33 mm,实验组分别为11.67 mm、12.00 mm。【结论】在聚维酮碘浓度为50、75、100、200和400μg/mL时,分别加入浓度为2μg/mL的硒,可增强其对SA、MRSA的杀菌效果、缩短作用时间。硒(SeNPs)加入PVP-I对SA、MRSA的杀菌效果均有增效作用。但增敏效果SA较MRSA显著。MRSA的增效作用对碘浓度(400μg/mL)需求较高。为临床精准选用消毒剂的浓度和作用时间,降低临床皮肤手术部位感染提供理论依据。

消毒剂聚维酮碘对养殖水体沉积物中氮循环微生物的影响

水产养殖中使用消毒剂杀死致病微生物的同时,也可能会对氮循环功能微生物产生毒害作用,进而影响水产养殖生态系统的氮循环。本文测定沉积物中氨氧化古菌(AOA)、氨氧化细菌(AOB)、亚硝酸盐氧化菌(NOB)以及反硝化细菌的丰度,结合水体氮素指标并利用16S rRNA基因高通量测序技术,研究聚维酮碘对养殖水体沉积物中氮循环微生物的影响。结果表明,聚维酮碘的添加影响了氮循环中NH4+向其他形式氮的转化,功能基因丰度层面聚维酮碘的使用抑制了AOA amoA、AOB amoA的增长;微生物群落结构层面聚维酮碘的添加使氨氧化菌属中Ellin6067属的基因丰度由增加73.40%变成了减少24.47%,说明聚维酮碘对Ellin6067属的基因丰度增长有较强的抑制作用。
