Abstract Purpose In the era of antibiotic resistance, there is an increased interest in antiseptic solutions that might represent a reliable option for ocular surface disinfection. The objective of this study is to compare for the first time three different antiseptic ophthalmic preparations to assess their in vitro antimicrobial activity. Methods The antiseptic activity of three commercial ophthalmic solutions, IODIM (povidone-iodine 0.6% in hyaluronic acid vehicle—Medivis, Catania, Italy), OZODROP (nanoemulsion with ozonated oil—concentration not specified—FBVision, Ophthalmic Pharmaceuticals, Rome, Italy), and DROPSEPT (chlorhexidine 0.02% and vitamin E 0.5% Tocopherol Polyethylene Glycol 1000 Succinate—TPGS, Sooft Italia, Montegiorgio, Italy), was tested in vitro on six reference strains by time-killing assays. Viable cells were evaluated after 1, 15, 30 min; 2, 6, and 24 h exposure by seeding 100 µl of the suspension (or appropriate dilutions) on LB agar or Sabouraud-dextrose agar. All plates were incubated at 37 °C for 24 h and evaluated by manually counting the colonies. Results IODIM solution showed a very rapid microbicidal activity: the number of viable cells for all the tested strains was under the detection limit (less than 10 CFU/ml) already after 1 min exposure, and this result was maintained at every incubation time. The rapid antimicrobial activity of povidone-iodine was not replicated when testing the other two antiseptics. Conclusions The study reports the great efficacy in reducing bacterial load in a very short time of povidone-iodine 0.6% compared with other antiseptic preparations.

Chlorhexidine was introduced almost seven decades ago and has a myriad of applications in dentistry. Few studies have evaluated the antimicrobial and antifungal capacity of different concentrations of chlorhexidine mouthwashes. Therefore, the aim of this study, was to evaluate in vitro, the antibacterial and antifungal capacity of three commercially available mouthwashes in Costa Rica, with different concentrations of chlorhexidine, 0.12%, 0.06%, and 0.03%. The experimental method selected was the Kirby-Bauer method to evaluate the antibacterial and antifungal effect of each compound by measuring the inhibitory effect on Staphylococcus aureus, Enterococcus faecalis, Escherichia coli, and Candida albicans strains, exposed to the antiseptic solutions. All samples showed some degree of antibacterial and antifungal effect. Even though we provide in vitro results, our findings are of relevance since all the species used in our experiment are microorganisms that may be present in dental plaque. Our results further support evidence that oral hygiene regimens may include mouthwashes with low doses of chlorhexidine and maintain reasonable antibacterial and antifungal efficacy.

Objective.To compare the effectiveness for prevention of central venous and arterial catheter colonization of 3 skin antisepsis with 1 of 3 antiseptic solutions: 10% aqueous povidone iodine (aqueous PI), 2% aqueous chlorhexidine gluconate (aqueous CG), and 0.5% alcoholic chlorhexidine gluconate (alcoholic CG).Design.Prospective, randomized controlled trial.Setting.Intensive care unit in a teaching hospital.Methods.Patients were randomly assigned to 1 of the 3 skin antisepsis groups. The distal tips of catheters were semiquantitatively cultured when the catheters were no longer necessary or if there was a suspicion of catheter-related infection. Rates of catheter colonization, catheter-related sepsis, and catheter-related bacteremia were compared among the 3 groups.Results.A total of 631 catheters were included in the study (194 from the aqueous PI group, 211 from the aqueous CG group, and 226 from the alcoholic CG group). The incidence of catheter colonization was significantly lower in the alcoholic CG than in the aqueous PI group (14.2% vs 24.7%; relative risk, 0.5 [95% confidence interval, 0.3-0.8; P < .01]); it was also significantly lower in the aqueous CG group than in the aqueous PI group (16.1 % vs 24.7%; relative risk, 0.6 [95% confidence interval, 0.4-0.9; P = .03]). There were no significant differences between the aqueous CG and the alcoholic CG groups. Incidences of catheter-related bacteremia were similar for all 3 groups. The aqueous and alcoholic CG solutions were superior to the aqueous PI solution in preventing catheter colonization due to gram-positive bacteria.Conclusions.The aqueous and alcoholic CG solutions for cutaneous antisepsis were similarly effective in preventing colonization of central venous catheters and arterial catheters. Both had significantly lower incidences of colonization than did the aqueous PI solution; this effect seems to be related to the CG solutions' more efficacious prevention of colonization with gram-positive bacteria.

The female genital tracts harbor a wide variety of microorganisms’ knowns as microflora mostly constituted by lactobacilli, involved in the healthy state of the vagina without causing infection. Urinary tract infections (UTI) are frequent in pregnant women due to physiological and anatomical changes that occur during pregnancy. These infections can result to disabilities or serious health problems both for the mother and the new-born. Vaginal douching has been reported among risky practices associate with UTIs. However, this remains debatable and contradictory when other studies report the benefit effects of vaginal cleaning in infection prevention. The aim of this study was to assess pregnant women behaviors and practices regarding genital hygiene. This was a cross sectional descriptive study conducted on exhaustive sample of pregnant women coming for antenatal visits in Lafé Sub-divisional Hospital (SDH) and Baleng Catholic Health Center (BCHC) between 16 and 30 September 2013. Data were collected using a paper based standardized questionnaire directly self-administered after obtain a free consent. Overall, 80 pregnant women were enrolled. The majority of them had attended at least primary education (97.5%; n=78/80) and many were lived in couple (81.25%; n=65/80). Almost one on three participants identified antenatal consultation (ANC) as a key element to be taken into account by pregnant women. 70.1% (n=56/80) of women declared wearing undergarments in cotton. Regarding the daily vaginal douching behaviors, the majority (76.3%; n=61/80) of participants used the recommended gynecological measure, while the remaining use self-prescribed measures. Both genital parts (vulva area and vagina) were cleaned and use of water was mostly cited (63.8%; n=51/80). Almost one participant on four (n=29/80) use antiseptic solutions for genital cleaning. Antiseptic solutions were associated with water in 34.5% of cases (n=10/29), and in 65.5% (n=19/29) of cases it was used only for the vagina. Our findings suggest that knowledge and genital hygiene cleaning practices are acceptable among our study population. Risky practices such as use of antiseptic solutions and synthetic underwear’s were reported. Skills of health care providers on good hygiene practices for pregnant should be improved and community-based communication strategies need to be implemented to reach all women of child bearing age.
