Refractory rhinosinusitis complicating immunosuppression: application of N-chlorotaurine, a novel endogenous antiseptic agent.

Severe infections are a frequent complication in immunosuppression following transplantations. In the case reported here, a heart-transplanted patient was treated for refractory rhinosinusitis with a combination of sinus surgery and rinsing with N-chlorotaurine (NCT). The daily rinse was well tolerated and effective. The combination of functional endonasal sinus surgery and topical treatment with NCT appeared effective and well tolerated in antibiotic-resistant sinusitis under immunosuppression.

Influence of the antiseptic agents polyhexanide and octenidine on FL cells and on healing of experimental superficial aseptic wounds in piglets. A double-blind, randomised, stratified, controlled, parallel-group study.

The main target of the combination of octenidine with phenoxyethanol (Octenisept) is the antisepsis of acute wounds, whereas polyhexanide combined with polyethylene glycol in Ringer solution (Lavasept) is the agent of choice for antisepsis of chronic wounds and burns. Because comparative data for both agents on the effects on wound healing are lacking, we investigated the influence of preparations based on polyhexanide and octenidine versus placebo (Ringer solution) in experimental superficial aseptic skin wounds (n = 108) of 20 mm diameter, using a double-blind, randomised, stratified, controlled, parallel-group design in piglets. Computerised planimetry and histopathological methods were used for the assessment of wound healing. Histologically, no significant differences could be verified at any time between the 3 groups. However, in the early phase (day 9 after wounding), the octenidine-based product retarded wound contraction to a significantly greater extent than placebo and polyhexanide, whereas in the later phase (days 18 and 28), polyhexanide promoted contraction significantly more than did placebo and octenidine. The consequence is complete wound closure after 22.9 days using polyhexanide, in comparison to the placebo after 24.1 days (p < 0.05) and octenidine after 28.3 days (no statistical difference to placebo). This may be explained by the better tolerance of polyhexanide in vitro, which was demonstrated with dose and time dependence in cytotoxicity tests on human amnion cells.

Amuchina 10% solution, safe antiseptic for preventing infections of exit-site of Tenckhoff catheters, in the pediatric population of a dialysis program.

Although, decreasing in incidence with the disconnection systems, the first complication is still peritonitis in patients with chronic renal failure and the second is infection of Tenckhoff catheter exit-site. All efforts made to diminish the frequency of exit-site infection lower the possibility of peritonitis. The pediatric population is well-known to have a major risk of infectious complications, and making easy and safe the care of the exit-site will prevent the peritonitis that follows. The aim of the study was to evaluate the efficacy of the Amuchina 10% solution vs. pH neutral soap in children with chronic renal failure, on preventing exit-site infection. There were 60 patients who were assigned randomly to one of two groups. One group used Amuchina 10% solution for the daily cleaning of the exit-site, and the other used pH neutral soap, with 14 months of follow-up. Before the study they have to be free of infection for at least 30 days. All were taught by the same nurse how to clean their exit-site. Groups were almost identical in years, sex, and time on dialysis. We had nine infections in the soap group and none in the Amuchina 10% solution group, with an OR: 17 (p = 0.004). From these nine infections, the bacteria isolated were: 4 (13%) were caused by Pseudomona aeruginosa, 1 (3.3%) by Staphylococcus aureus, coagulase-positive staphylococci in 2 (6.6%) and Serratia marcensens in 1 (3.3%). In conclusion, Amuchina 10% solution is effective in preventing infection on the exit-site, without any secondary topical reaction.

Effect of antiseptic cord care on bacterial colonization in the newborn infant.

A randomized controlled study was undertaken to compare the effectiveness of three umbilical cord treatment regimens in controlling neonatal bacterial colonization. The regimens studied included daily application of castile soap, triple dye and silver sulfadiazine. The triple dye and silver sulfadiazine regimens inhibited bacterial colonization. Staphylococcal colonization was inhibited most effectively by triple dye treatment. Group B streptococcal colonization was equally inhibited by triple dye and silver sulfadiazine. Silver sulfadiazine was more effective in controlling colonization with gram-negative microorganisms.

Comparison of bactericidal effects of commonly used antiseptics against pathogens causing nosocomial infections. Part 2.

Opportunistic infections caused by gram-negative rods (GNR), conventionally regarded as organisms with low or no pathogenicity, and intractable infections caused by various resistant organisms pose a great problem now. In view of this, we determined the bactericidal effects of 5 commonly used disinfectants using as the test strains Xanthomonas maltophilia and Serratia marcescens, chosen among other GNR since they often cause nosocomial infections. Regarding the bactericidal activities against X. maltophilia and S. marcescens, both sensitive strains and resistant strains were killed within 20 s of exposure to povidone-iodine and sodium hypochlorite. With chlorhexidine, 1 strain each of both species was not killed within 10 min of exposure at a concentration of 0.2%. Both sensitive strains and resistant strains of X. maltophilia were killed within 20 s of exposure to benzalkonium at 0.02%, while a concentration of 0.1% was required for benzalkonium to kill S. marcescens within 20 s. With Tego-51, both sensitive strains and resistant strains of X. maltophilia were killed within 20 s at 0.02%, while 1 strain of S. marcescens was not killed within 20 s at a concentration of 0.1%. In the use of disinfectants, comparative bactericidal effects of various disinfectants against clinical isolates should be taken into consideration.
