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. Main results: The 23 patients in 12.5% PPO group had similar baseline demographic and clinical characteristics as the 23 patients in the 2% MO group. Within 7 days from the start of intervention, 15 of the 23 patients (65.22%) in the PPO group and 19 of the 23 patients (82.61%) in the MO group had clinical success (p=0.1792). Conclusion Pomelo peel ointment is as efficacious as mupirocin ointment in the management of localized impetigo contagiosa.

AIMTo study the effect of both light and heat on the stability of furacilin aqueous solution and the probability of substituting for isothermal accelerated tests by nonisothermal accelerated tests upon exposure to light at high temperatures.

METHODSThe isothermal and nonisothermal accelerated tests were employed. The accelerated tests were proceeded in the dark and exposed to light at high temperature. Tungsten, ultraviolet and fluorescent lamps were employed in exposure tests.

RESULTSThe degradation of furacilin aqueous solution in isothermal heating experiments or the exposure experiments to light at high temperatures obeys zero-order kinetics. The total degradation rate constant k caused by both light and heat can be divided into two parts: k = kdark + klight, where kdark and klight are the degradation rate constant caused by heat and light, respectively. The klight can be expressed as klight = Alight.exp(-Ea,light/RT).E, where E is the illuminance of light; Alight and Ea,light are both experimental constants. The parameters obtained in nonisothermal accelerated tests were comparable to those obtained in classic isothermal accelerated tests.

CONCLUSIONNonisothermal accelerated tests may substitute for isothermal accelerated tests during the study of the effects of both light and heat on the stability of drugs, in order to save time, labor and drugs.

Oral aphthous ulcer is a common lesion characterized by loss of dermal tissue of various shapes in many diseases. It is not serious, but may affect quality of life through pain and discomfort. In many cases, it heals spontaneously without treatment or with topical agents such as antiseptics, analgesics and corticosteroid in a few days. However, rarely, there are a few cases of aphthous ulcer that remain refractory despite appropriate treatment. Tumor necrosis factor-α inhibitors have recently been used in treatment of severe mucosal ulcer in Behçet's disease. Herein, we report a patient suffering from refractory oral aphthous ulcers that were resistant to topical and systemic agents, but were successfully treated with adalimumab.

Antiseptics are substances that kill or prevent the growth of microorganisms when applied to living tissue. They must be effective against microorganisms but must also retain their activity in presence of body fluids without being harmful locally or systemically. Among many antiseptics, Betadine(R) has been widely used because of its low toxicity and high germicidal efficacy. We reported 2 cases of allergic contact dermatitis to Betadine(R) in surgical patients. They had eczematous eruption along the Betadine(R) applying sites. Path tests Betadine(R) confirmed the diagnosis.

PURPOSE: Two antiseptic solutions were investigated for their effect on bacterial growth inhibition. MATERIALS AND METHODS: A total of 38 patients were included in this study, who visited Daegu Catholic Medical Center from August 2, 2011 to September 2, 2011. Bacterial culture was performed at the pre-scrub, post-scrub, and postoperation; patients were divided into two groups according to use of povidone iodine (3.75%) and povidone iodine with Softa-Man(R) as antiseptic agents at the surgical. RESULTS: Comparison between the antiseptic solutions showed a significant difference for the presence of gram positive cocci (p=0.034), however, no difference was observed for the presence of gram positive bacilli (p=0.838). As the scrub time increased, the positive detection ratio of bacteria decreased (p=0.000), and decreased significantly at more than 120 seconds. However, positive detection ratio of bacteria increased significantly at more than 300 seconds in cases with povidone iodine only (p=0.014). Glove wearing time did not have a significant influence on the positive detection ratio of bacteria, and no significant difference was observed between the antiseptic solutions (p=0.143). CONCLUSION: Considering the positive detection ratio of bacteria when using povidone iodine only, the appropriate scrub time should be between 4 and 5 minutes. When using both antiseptics, at least 2 minutes of scrub time is needed.

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.

OBJECTIVE: To compare the effect on Total Aerobic Count (TAC) of application of Isopropyl alcohol, Chlorhexidine, and povidone iodine plus alcohol prior to venipuncture and development of phlebitis in children admitted at a tertiary hospital.

METHODS: A prospective randomized clinical trial in a tertiary hospital in Quezon City. A total of 129 patients one-year old and above with physician orders for IV insertion and extractions. Pre and post swabbing of the venipuncture site was done and placed on a blood agar plate. The three antiseptic solutions were applied over the venipuncture site and swabbed and placed on the agar plate. The primary outcome measure was the TAC in each blood agar of the tested antiseptic solution and correlation to developing phlebitis.

RESULTS: The CFU/mL after disinfection was significantly different between groups, with the lowest CFU/mL observed among patients disinfected with Chlorohexidine. Phlebitis was only noted in the alcohol group. No reactions were observed from patients who were disinfected with povidone iodine and chlorohexidine.

CONCLUSIONS: Single application of Chlorhexidine is the optimal method to be used as antisepsis prior to procedures like venipuncture. However, the use of povidone iodine plus 70% isopropyl alcohol also has comparable effect to 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.

Several 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.

Povidone-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
