OBJECTIVES:
This study aimed to evaluate the therapeutic effect of 1% povidone-iodine mouthwash combined with scaling and root planing in patients with stage Ⅰ/Ⅱ class A/B periodontitis, and to provide a basis for the clinical application of povidone-iodine mouthwash.
METHODS:
Seventy-five subjects were included in this trial and randomly divided into three groups. After full-mouth ultrasonic supragingival cleansing, scaling and root planing, the placebo group was treated with sodium chloride injection (NaCl group), the control group was treated with compound chlorhexidine mouthwash (CHX group), and the experimental group was treated with 1% povidone-iodine mouthwash (PVP-I group), and rinsed their mouths for 1 week, respectively. Subjects were tested at 1, 4, and 12 weeks after dosing for clinical indicators, microbial composition of supragingival plaque, gingival crevicular fluid inflammatory marker levels, and patient-reported outcomes.
RESULTS:
Sixty-three subjects completed the follow-up. After treatment, the clinical indicators, microbial indicators, and inflammatory indicators were all significantly improved (P<0.05). Comparisons among the groups showed that one week after treatment, the bleeding index and plaque index of the CHX group and the PVP-I group were lower than those of the NaCl group, and the plaque index of the CHX group was lower than that of the PVP-I group (P<0.05). There were no statistically significant differences in the other clinical indicators among the groups (P>0.05). Twelve weeks after treatment, the Shannon index of the CHX group was lower than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other microbial indicators among the groups (P>0.05). Twelve weeks after treatment, the interleukin-10 concentration of the CHX group was higher than that of the NaCl group (P<0.05), and there were no statistically significant differences in the other inflammatory indicators among the groups (P>0.05). The PVP-I group had the highest scores in terms of taste and oral odor. There was no obvious staining on the tooth surfaces and mucosa in all three groups.
CONCLUSIONS
1% PVP-I mouthwash combined with scaling and root planing can effectively reduce gingival inflammation and dental plaque, improve clinical symptoms in the short term. While its efficacy is not significantly inferior to that of chlorhexidine, PVP-I mouthwash is more acceptable to patients than chlorhexidine.

BACKGROUND AND OBJECTIVE
The human nasal passages host major human pathogens. Recent research suggests that the microbial communities inhabiting the epithelial surfaces of the nasal passages play a key factor in maintaining a healthy microenvironment by affecting both resistance to pathogens and immunological responses. Colonization of the nasal cavity by different pathogens such as Staphylococcus aureus and Klebsiella aerogenes, is associated with a higher postoperative infection morbidity. Povidone-iodine (PVP-I) as an antiseptic has been proven to display high antibacterial, antiviral, and antifungal properties even at low concentrations, and was shown to be effective in the control of infections to limit their impact and spread. It can be used as a topical antiseptic for skin decontamination and wound management, as a nasal spray, or as a gargle. There are different methods in testing the efficacy of potential antimicrobial suspensions. This study aimed to determine the concentration of PVP-I that is most effective in nasal decolonization using microsuspension test and colorimetric minimum inhibitory concentration (MIC) determination assays, resazurin microtiter assay (REMA), and Dey-Engley (D/E) neutralizer assay. The findings of this study will contribute to knowledge regarding the intended use of PVP-I in microbial control, particularly in bacterial infections.
METHODSSeveral dilutions (2.0%, 1.0%, 0.5%, 0.25%, 0.1% and 0.09%) of commercially bought 10% (10 mg per 100 ml) povidone-iodine were prepared and tested against a standardized inoculum (1x105) of Staphylococcus aureus and Klebsiella aerogenes at different contacttimes (5 seconds, 10 seconds, 30 seconds, 1 minute, and 5 minutes). Microdilution suspension test was performed to determine the log reduction per variable, while REMA and D/E neutralizer assay were used to determine the MIC. A value of greater than or equal to 5 log reduction was considered effective for microdilution suspension test. Estimates of agreement statistics were used to interpret the results of the assay in which the overall percent agreement (OPA), positive percent agreement (PPA), negative percent agreement (NPA), and Cohen’s kappa statistics were calculated.
RESULTSPovidone-iodine concentration of 0.25% exhibited ?5 log reduction against K. aerogenes at the minimum contact time of 5 seconds. On the other hand, a slightly higher PVP-I concentration was required to achieve ?5 log reduction for S. aureus at 0.5% concentration and a minimum contact time of 1 minute. There was an observed concordance of the results of REMA and D/E neutralizer as MIC colorimetric indicators, which yielded an overall test percent agreement of 90.30% (95% CI: 84.73–94.36), and a strong level of agreement (? = 0.8, pCONCLUSION
Low povidone-iodine concentrations (i.e., 0.5% against S. aureus and 0.25% against K. aerogenes) were observed to have bactericidal activity of at least 5 log reduction as rapid as the minimum contact time of 5 seconds. Furthermore, D/E and REMA, as colorimetric indicators, had comparable performance (OPA = 90.30%; ? = 0.8, p

During the recent emergence of COVID-19, an increased practice of hand hygiene coincided with the reduced incidence of the norovirus epidemic in Japan, which is similar to experience with the pandemic flu in 2009. We investigated the relationship between the sales of hand hygiene products, including liquid hand soap and alcohol-based hand sanitizer, and the trend of norovirus epidemic. We used national gastroenteritis surveillance data across Japan in 2020 and 2021 and compared the base statistics of incidence of these two years with the average of the previous 10 years (2010-2019). We calculated the correlations (Spearman's Rho) between monthly sales of hand hygiene products and monthly norovirus cases and fitted them to a regression model. In 2020, there was no epidemic, and the incidence peak was the lowest in recent norovirus epidemics. In 2021, the incidence peak was delayed for five weeks to the usual epidemic seasons. Correlation coefficients between monthly sales of liquid hand soap and skin antiseptics and norovirus incidence showed a significantly negative correlation (Spearman's Rho = -0.88 and p = 0.002 for liquid hand soap; Spearman's Rho = -0.81 and p = 0.007 for skin antiseptics). Exponential regression models were fitted between the sales of each hand hygiene product and norovirus cases, respectively. The results suggest hand hygiene using these products is a potentially useful prevention method against norovirus epidemics. Effective ways of hand hygiene for increasing the prevention of norovirus should therefore be studied.

Inflatable penile prostheses are an important tool in the treatment of medically refractory erectile dysfunction. One of the major complications associated with these prostheses is infections, which ultimately require device explanation and placement of a new device. Over the past several decades, significant work has been done to reduce infection rates and optimize treatment strategies to reduce patient morbidity. This article reviews the current state of knowledge surrounding penile prosthesis infections, with attention to the evidence for methods to prevent infection and best practices for device reimplantation.

Background:
Extracts from several citrus plants have antimicrobial properties and have been used for certain infectious skin conditions.
Objective:
To compare the efficacy of 12.5% pomelo peel ointment and 2% mupirocin ointment in the management of localized impetigo contagiosa.
Design:
Randomized, double-blind, controlled trial.
Setting:
Dermatology Outpatient Clinic in Southern Philippines Medical Center, Davao City, from September 2012 to November 2012.
Participants:
46 male and female patients, aged 2-15 years old, and clinically diagnosed with localized impetigo contagiosa.
Interventions :
Participants were randomized to receive either 12.5% pomelo peel ointment (PPO) or 2% mupirocin ointment (MO), thinly applied on impetigo lesions twice daily for 7 days.
Main outcome measures:
Clinical success defined as either ‘complete resolution of lesions’ or ‘dryness of the lesions without crusts, with intact skin, and with no to minimal local erythema’ at any time within 7 days from the start of intervention.

Journal of Korean Burn Society 2018;21(1):31-38
PURPOSE: It is well known the advantages of scalp donor split thickness skin graft(STSG) in deep burn wound because of its scarless donor healing, and good color match in face. Inspite of the advantages of scalp as a skin donor site during split thickness skin graft some authors report the frequent postoperative folliculitis, and partial alopecia on scalp donor site. We had experienced 21 burn patients, who had full thickness skin defects caused by burn injuries, were successfully managed with scalp donor split thickness skin graft with our optimal donor management protocols. METHODS: We had 21 deep burn patients, who were managed with thin STSG from scalp donor for coverage of full thickness skin defects. The operative techniques of the harvesting scalp STSG, and scalp donor dressing care are such as followings. After the infiltration of the donor scalp area with 1:1,000,000 epinephrine diluted with saline, then usually 0.012~0.015 inch thickness skin were harvested with air driven Zimmer® dermatome. On postoperative 6days, the one layer of adhered Vaseline gauze at donor scalp site was manually removed, and the entire scalp was cleansed with water. After then the daily hair washing was continued to remove the desiccated scaly crust with thick exudate at the growing hair and follicle. RESULTS: The scalp split thickness skin graft at the recipient sites in 21 burn patients were survived completely. Ranges of patient's age were 8 months to 56. The size ranges of scalp STSG were 2×2 cm~12×15 cm. The grafted scalp donor STSG were survived in all cases. The mean epithelialization period of scalp donor was 7.2 days. The one case of transient folliculitis (5%) from the postoperative 8days was occurred, and it was disappeared slowly with vigorous daily hair washing, antiseptics and systemic antibiotics. In all cases, there was no micro-alopecia or alopecia, and scars in scalp donor after follow ups. The donor site pain was markedly disappeared within 1~2 postoperative day. The hemorrhage from the scalp donor site during operation was not noticeable. The newly growing hair at the scalp donor was noted from the 3 postoperative days by palpation or unaided eye through the Vaseline gauze dressing. The average lengths of newly growing hair shaft are 2~3 mm in postoperative 8 days, 5~6 mm in postoperative 14 days. CONCLUSION: We had successful reconstruction of postburn skin defects using scalp donor split thickness skin graft without donor scars, persistent folliculitis or alopecia on scalp donor. From the postoperative 6~7 days after harvesting the scalp donor STSG, early vigorous daily washing with water and open dressing of scalp donor site should be recommended in order to prevent folliculitis. After long-term follow ups, the scalp split skin grafted recipient sites showed reliable, and relatively good color match with surrounding skin in face and dorsum of hand.

PURPOSE: Nosocomial infections account for one of the most serious complications in hospitalized patients around the world. Surgical site infections have significant economic implications, and surgical antisepsis plays an important role in such processes. METHODS: With prior approval by the Institutional Review Board and informed consent, 10 volunteers were randomly assigned to 3 protocols on hand antisepsis: protocol A (chloroxylenol 3%), protocol B (benzalkonium chloride at 1%), and protocol C (ethyl alcohol 61%, 1% chlorhexidine gluconate). Smears from both hands were cultured after each hand pro tocol (t0) and at the end of suturing (t1). Colony forming units were counted (CFUs on blood agar dishes) with digital counting software (Open CFU). Friedman test was used to compare the mean values among the groups, and a Bonferroni correction was made to determine the dissimilar group, with a P = 0.015. RESULTS: At t0 for protocol A the CFU count was 82.8 ± 1.3; protocol B was 9.7 ± 30; protocol C was 0.1 ± 0.3 (P < 0.001). At t1 for protocol A the CFU was 80.7 ± 89.4; protocol B was 7.5 ± 32; protocol C was 0.0 ± 0.0 (P < 0.001). No adverse events were present among the subjects. CONCLUSION: Ethyl alcohol at 61% with 1% chlorhexidine gluconate showed higher efficacy than the traditional washing antiseptics.
