Disinfection of the skin with detergent preparations of Irgasan DP 300 and other antiseptics.

An evaluation of the relative effectiveness of 2% hexachlorophane and 0.75% Irgasan DP 300 bar soaps in disinfection of the hands showed that the former caused a significantly larger reduction in natural skin bacteria than the latter after one handwash and after six handwashings, three on each of two successive days. Repeated use of Irgasan DP 300 bar soap caused a significantly greater reduction in skin flora than repeated handwashings with unmedicated bar soap, but a single handwash gave no significant reduction in skin flora compared with a single use of the unmedicated soap.In a comparison of a 4% chlorhexidine detergent solution a 3% hexachlorophane detergent cream and a 2% Irgasan DP 300 detergent solution the 4% chlorhexidine detergent gave the largest mean reduction in skin bacteria after one handwash and after six handwashings and 2% Irgasan DP 300 a poor and erratic reduction after a single handwash. After six handwashings all three preparations gave large reductions in skin bacteria. The 2% Irgasan preparation showed some residual activity on the skin after handwashing though less than that with chlorhexidine and with hexachlorophane-chlorocresol detergent preparations.

Antiseptic efficacy of local disinfecting povidone-iodine (Betadine) therapy in chronic wounds of lymphedematous patients.

In chronic wounds (ulcus cruris) of lymphedematous patients (n = 25) opportunistic infections caused by gram-negative rods and methicillin-resistant Staphylococcus aureus can be detected in 35% of cases. The healing of the wound takes a long time, which is the reason why the patients are taught how to manage the wound care. Local antibiotics must be avoided. The elimination of the wound infections is the first step of the complex decongestive physiotherapy. The infection aggravates the lymphostasis and makes the complaints of the patients (inflammation, pain, odor) more unacceptable, the systemic infections (erysipelas, lymphadenopathy, fever) more probable and the costs of the treatment higher. Betadine solution and ointment were used locally. The clinical and bacteriological efficacy of povidone-iodine has been validated. Excellent local tolerability has also been observed. The opinion of the patients was registered on a visual analog scale and statistically analyzed. No development of resistance has been noted. For local treatment, Betadine proved to be an effective preparation tolerable for a long time in the treatment of chronic wounds.

Antiseptic effect of a topical dermatological formulation that contains Hamamelis distillate and urea.

OBJECTIVE: To determine the antimicrobial activity of a distillate of Hamamelis (Aqua Hamamelidis ), United States Pharmacopoeia (USP) 23, and urea formulated as a topical dermatological preparation that contains both active ingredients. METHODS: Using the simple occlusion test and expanded flora test, we conducted in vivo studies in 15 healthy volunteers. We also performed in vitro studies using the agar diffusion test. RESULTS: The occlusion test and expanded flora test demonstrated significant antimicrobial activity for a product containing the Hamamelis distillate (90%) and urea (5%) among other ingredients. The expanded flora test demonstrated significant antimicrobial activity for both Hamamelis distillate and urea. The simple occlusion test showed the same tendency, but results were not significant. The agar diffusion test showed inhibition of Staphylococcus aureus and Candida albicans, among other organisms. Comparison with earlier studies of chlorhexidine digluconate and fuchsine using the same method showed that the antimicrobial activities of Hamamelis distillate and urea were relatively weak. This finding is supported by the weak inhibitory activity observed in the agar diffusion test (using 100% of the finished dosage form). CONCLUSION: Formulations of Hamamelis distillate and urea are mainly used for their antiinflammatory, hydrating, and barrier-stabilizing effects in dermatitis maintenance therapy. As bacterial colonization has a central role in the pathogenesis of atopic dermatitis and intertrigo, the antimicrobial activity of such products is considered a welcome, added benefit.
