The results of ingredient patch testing in contact dermatitis elicited by povidone-iodine preparations 总被引:4,自引:0,他引:4
10 cases of contact dermatitis which began during the application of povidone-iodine preparations were examined with patch tests using 2 kinds of povidone-iodine preparations and their ingredients, i.e., povidone-iodine, polyoxyethylene nonylphenyl ether and glycerin, and also the components of povidone-iodine, i.e., iodine and polyvinylpyrrolidone. All 10 cases reacted positively to the povidone-iodine preparations and povidone-iodine, 3 out of the 10 to polyoxyethylene nonylphenyl ether, 1 out of the 9 tested to iodine, while no positive response was found to glycerin or polyvinyl-pyrrolidone. It was difficult to distinguish between allergic responses from irritation, as responses to patches of povidone-iodine and its preparations usually include irritation at high frequencies. Based on comparison of results with a control group, however, those showing + or stronger reactions to 2% povidone-iodine at days 3 to 5 were considered to be allergic. Thus, 4 out of the 10 cases were considered as sensitization to povidone-iodine. Another 3 cases were found to be polyoxyethylene nonylphenyl ether sensitized, and another 1 iodine sensitized, while the patch test reactions of the other 2 were considered to have been elicited by irritation. 相似文献

Antiseptic agents can cause skin irritation and lead to severe problems, especially for individuals with atopic diatheses. We investigated the effect of 4 different antiseptic agents using an atopic dermatitis (AD) model mouse. NC/Nga mice were subcutaneously injected with mite allergen (Dp) to induce AD-like skin lesions (ADSLs), and an application of 0.2% (w/v) benzalkonium chloride (BZK), 10% (w/v) povidone-iodine (PVP-I), 80% (v/v) ethanol (Et-OH), or 0.5% (v/v) chlorhexidine gluconate (CHG) was applied to the ear envelope. BZK induced a significant increase in the severity of the clinical score, infiltration of inflammatory cells, local expression of inflammatory cytokines in subcutaneous tissue, and total serum immunoglobulin (Ig) E. PVP-I increased the clinical score, number of mast cells, and production of inflammatory cytokines, and total serum IgE. Et-OH increased the clinical score and number of inflammatory cells, but showed no effect on serum IgE levels. No differences in any parameters were observed between CHG and the vehicle. Collectively, the results suggest the severity of the ADSL was related in part to the strength of the immunoreaction. These findings suggest that CHG could offer the lowest risk of inducing ADSL in individuals with atopic dermatitis and that medical staff and food handlers with AD could benefit from its use. 相似文献

Background
Irrigation and debridement with modular component and liner exchange (IDLE) is a low morbidity procedure for treatment of periprosthetic joint infection (PJI) with reported failure rates exceeding 50%. Dilute povidone-iodine lavage has been shown to be safe and effective in decreasing acute PJI in primary total joint arthroplasty. Vancomycin powder has also shown to be effective in preventing infection in spine surgery. We hypothesize that a vancomycin povidone-iodine protocol (VIP) used in conjunction with IDLE can increase infection-free survivorship after acute PJI.Methods
This is a single institution retrospective review of all PJIs treated with IDLE and VIP since March 2014. A consecutive matched control group of patients treated with IDLE for PJI for 2 years prior to March 2014 was also included for analysis. Primary outcome was failure, defined as return to operating room for an infection-related problem. Secondary outcome was chronic suppression with antibiotics at final follow-up. Minimum follow-up was 1 year.Results
A total of 36 patients in the VIP group and 38 patients in control group were identified. In the VIP group, 16.7% (6/36) failed at final follow-up compared to 37% failure rate (14/38) in the control group (P < .05). Three patients in the VIP group were on chronic antibiotic suppression at final follow-up. There were no medical complications secondary to the VIP.Conclusions
The VIP group demonstrated a significant reduction in reinfection and failure rate following IDLE. The authors believe that a VIP is an effective adjunct for treating PJI with irrigation and debridement. 相似文献37.

目的研究聚维酮碘消毒粉动物亚急性毒性,了解其应用的安全性。方法采用动物试验法和生化检验方法进行聚维酮碘亚急性毒性评价。结果在聚维酮碘给药观察期间,大鼠雄鼠高、中剂量组出现体重增长减慢,食物利用率降低等对生长发育的影响。试验动物血常规检验血红蛋白含量下降。试验动物各剂量组血清胆固醇和甘油三脂虽在正常波动范围,但血清胆固醇水平随剂量加大升高,甘油三酯水平有下降的趋势。高剂量组雌雄大鼠肾脏出现轻度肾小管变性等病理改变。结论聚维酮碘亚急性毒性试验表现出对动物有轻微毒性反应,此可能与过量碘摄入有关,提示聚维酮碘消毒剂不可长期大剂量使用和直接进入胃肠道。 相似文献

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±14.76y. 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. 相似文献

ObjectiveThis systematic review aimed to evaluate the antiviral effect of mouthwashes against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Material and methodsAn electronic search was performed on PubMed, Scopus, Web of Science, Cochrane Library, LILACS, ProQuest, and Google Scholar, and was complemented by a manual search. Both clinical and in vitro studies that focused on the antiviral effect of mouthwashes against SARS-CoV-2 were included. Risk of bias assessment was performed only on the clinical studies using the RoB-2 and ROBINS-I tools.ResultsA total of 907 records were found; after initial selection by title and abstract, 33 full-text articles were selected to be evaluated for eligibility. Finally, a total of 27 studies were included for the qualitative synthesis, including 16 in vitro studies and 11 clinical trials. Antiviral effects were evaluated separately for the in vitro and clinical studies. In vitro studies included mouthwashes containing hydrogen peroxide, chlorhexidine digluconate, povidone-iodine, essential oils, cetylpyridinium chloride, and other compounds; in vivo studies included mouthwashes containing hydrogen peroxide, chlorhexidine digluconate, povidone-iodine, cetylpyridinium chloride, essential oils, chlorine dioxide, β-cyclodextrin-citrox, and sorbitol with xylitol. Povidone-iodine, cetylpyridinium chloride, and essential oils were effective in vitro, while hydrogen peroxide, chlorhexidine digluconate, povidone-iodine, cetylpyridinium chloride, β-cyclodextrin-citrox, and sorbitol with xylitol were effective in vivo. Unclear or high risk of bias was found for almost all clinical studies, and only one study presented with a low risk of bias. No further quantitative analysis was performed.ConclusionAlthough povidone-iodine, cetylpyridinium chloride, and essential oils may be an alternative to reduce the viral load in vitro and in vivo, more studies are needed to determine the real antiviral effect of these different mouthwashes against SARS-CoV-2.This work was not funded. The protocol was registered in PROSPERO (identification number: CRD42021236134). 相似文献
