Several pre- and intraoperative factors have been associated with incisional surgical site infection (SSI), but little is known about the influence of postoperative wound care and especially, the use of different dressings on incisional SSI. The aim of this study was to compare 3 methods of wound dressings (conventional dressing, silver-containing dressing, and mupirocin ointment dressing) for their ability to prevent SSI, as measured by SSI rates, in patients with colorectal cancer undergoing elective open surgery.. A prospective, randomized study was performed. Inclusion criteria were diagnosis of colorectal neoplasms and plans to undergo elective surgery with curative aims. Patients were randomized using a 1:1:1 allocation into 3 groups: patients receiving an ionic silver-containing dressing (ISD) (group 1), a mupirocin ointment application (MOA) (group 2), and a conventional dressing (group 3 or standard dressing). The primary outcomes variable was occurrence of incisional SSI. Follow-up was 30 days postoperatively.. A total of 147 patients were included, 49 in each group. Incisional SSI occurred in 9 patients (18.4%) in the ISD group, 2 (4.1%) in the MOA group, and 10 (20.4%) in the standard dressing group (p = 0.028). Adjusting for multiple comparisons, there were no significant differences between ISD and standard dressing groups; a significant difference was observed between ISD and MOA (relative risk [RR] 4.5; 95% CI (1.1 to 19.8); p = 0.046) and between the standard group and the MOA group (RR 5; 95% CI (1.2 to 21.7); p = 0.031).. Topical application of mupirocin ointment achieves better results for the prevention of SSI than ionic silver-containing dressing or standard dressing in patients undergoing elective open colorectal surgery.

One hundred fifty-three strains of Staphylococcus aureus recovered from infected eczema frequently demonstrated resistance to multiple antibiotics. Penicillin and ampicillin resistance was extremely frequent (88%), methicillin resistance was found in nearly 14% of strains, and erythromycin and tetracycline resistance was present in 16%. S. aureus strains were uniformly sensitive to vancomycin, mupirocin, and cephalosporins. Experimental infections in human volunteers showed topical therapy with 2% mupirocin was more effective than oral erythromycin in suppression of both S. aureus and Streptococcus pyogenes.

Sixty patients participated in a bacteriologically controlled, randomized, parallel group comparison of 2% mupirocin ointment (Bactroban) and oral erythromycin ethylsuccinate for the treatment of impetigo. The trial included clinical and bacteriologic evidence and safety assessments. The Investigator's Global Evaluation, which compared the overall efficacy and safety of the trial drugs, demonstrated a more favorable performance for the mupirocin regimen. This difference was statistically and clinically significant. There were no significant differences between the trial regimens for any of the other efficacy variables examined. The bacteriologic success rate was 100% for both treatment groups. There was a clinically significant difference in adverse experience rates between treatment groups, with four (13%) of the erythromycin-treated patients reporting six adverse experiences versus none of the mupirocin-treated patients. The results of the trial indicate that 2% mupirocin ointment is as safe and effective as oral erythromycin ethylsuccinate in the treatment of patients with impetigo.

A double-blind, randomized, vehicle-controlled study was conducted to evaluate the safety and efficacy of 2% mupirocin ointment in the treatment of secondarily infected dermatoses. One hundred six patients were enrolled, 92 of whom were evaluable for efficacy. There was a significantly greater rate of eradication of Staphylococcus aureus and total pathogens in mupirocin-treated patients than in control subjects. Analysis of the clinical data relative to all pathogens showed a significant difference in skin infection evaluations performed at the interim and follow-up visits, which favored the mupirocin-treated groups. In those patients infected with S. aureus or Streptococcus pyogenes, there was a significant difference at end-point that favored mupirocin in seven clinical ratings and the skin infection evaluation at follow-up. Mild local adverse effects were noted in a small percentage of patients in each group. Mupirocin appears to be safe and effective for the treatment of secondarily infected dermatoses, especially in those infections caused by Staphylococcus aureus.

A trial was carried out in general practice in 200 patients presenting with skin infections to compare topical antibiotic treatment with mupirocin ointment with orally administered flucloxacillin or erythromycin. Patients were assigned at random to receive 4 to 10 days' treatment with either mupirocin applied 3-times daily or one of the oral antibiotics in the dosage normally used by the general practitioner for skin infections. The majority of infections were impetigo and infected wounds/lacerations; the main organisms isolated initially from 127 of the patients were either Staphylococcus aureus or beta-haemolytic Group A streptococci. Clinical response to mupirocin ointment (86% cured, 13% improved) was significantly better than that seen with erythromycin (47% cured, 26% improved) and similar to that with flucloxacillin (76% cured, 23% improved). Treatment outcome was not related to treatment duration with either the topical or oral preparations. Post-treatment samples from 76 patients showed that in the mupirocin group all the pathogens originally isolated were eliminated, including Gram-negative organisms.

Cutaneous larva migrans (CLM) is a parasitosis frequently seen in persons who have travelled to tropical or subtropical regions and in those who have worked in contact with soil. The disease frequently develops due to Ancylostoma braziliensis and Ancylostoma caninum species. After penetrating the skin and entering the body, the hookworm larva proceeds to bore tunnels through the epidermis, creating pruritic, erythematous, serpiginous lesions. Secondary bacterial infections of the lesions can often be seen, especially on the legs and buttocks. In this article we presented three atypical local cases which have not been declared previously in our country. The first case, a 54-year-old male who was admitted to hospital in August with complaints of an obverse body rash and itching lasting for a week. Eruptions were observed over a small area on the right side of the abdomen, consisting of itchy, raised, erythematous, curvilinear string-like lesions. Moreover, no eosinophilia was detected in the patient, whose culture showed a growth of Streptococcus pyogenes. The patient was clinically diagnosed with CLM accompanied by secondary bacterial infection and treated for three days with 1 g of amoxicillin-clavulanic acid, mupirocin cream and albendazole 400 mg/d. Under this regime, the lesions were seen to decline. The second case, a 38-year-old male was also admitted in August, complaining of itching and redness on his body. The patient, whose blood count values were normal, exhibited itchy, raised, serpiginous string-like lesions located on the left side of his body. The patient, whose bacterial culture was negative, was clinically diagnosed as CLM and treated for three days with albendazole 400 mg/d and the lesions were seen to improve. The third case, a 23-year old male was admitted in September complaining of itching and redness on his neck. An itchy, crescent-shaped erythematous lesion was detected on his neck; bacteriological cultures and blood count were normal. The common feature for all three cases was the story of working in a hazelnut orchard and mowing weeds using a motorized string trimmer (weed whacker). None of them had a history of travel outside the country. Therefore CLM assumed to be occurred due to the aeration of surface earth layer with the force of motorized string trimmer and entrance of the larvae were from the open parts of the body. In conclusion, it should be keep in mind that hookworm larva-related CLM can be encountered in our country,

We describe a woman with perianal and periumbilical dermatitis secondary to group G Streptococcus, summarize the salient features of this condition, and review other cutaneous conditions that clinically mimic streptococcal dermatitis of the umbilicus.. Periumbilical and perianal streptococcal dermatitis are conditions that commonly occur in children and usually result from beta-hemolytic group A Streptococcus. Rarely, non-group A streptococcal and staphylococcal infections have been reported in adults.. A 31-year-old woman developed perianal and periumbilical group G streptococcal dermatitis. Symptoms were present for six months and were refractory to clotrimazole 1 percent and betamethasone dipropionate 0.05 percent cream.. The etiology of perianal and periumbilical dermatitis is unclear, but is perhaps explained by virulence of previously asymptomatic colonized bacteria. Perianal streptococcal dermatitis is more common in children. A number of adult infections have been reported, most of which were secondary to group A beta-hemolytic Streptococcus. Men are more often affected than women. Group G Streptococcus is rarely the infective etiology of perianal streptococcal dermatitis. This condition presents as a superficial well demarcated erythematous patch on clinical examination. Diagnosis is ascertained by diagnostic swabs and serological tests: antistreptolysin O (ASO) or anti-DNase titer. Treatments include oral amoxicillin, penicillin, erythromycin, and mupirocin ointment.. Our patient expands on the clinical presentation typical of streptococcal dermatitis. We describe a rare occurrence of an adult woman infected with non-group A Streptococcus. Several conditions can mimic the presentation of perianal streptococcal dermatitis. Although rare, group G Streptococcus should be considered in the setting of virulent infections usually attributed to group A species. Streptococcal dermatitis can be added to the list of conditions affecting the umbilicus.

The skin infections are common in pediatrics, ranging from furonculosis or impetigo to the severe forms of necrotizing dermohypodermitis. The general antibiotic treatments are not always indicated but when they are, they must take into account the resistance of two main species of bacteria (Staphylococcus aureus and Streptococcus pyogenes), the pharmacokinetics-pharmacodynamic parameters and the severity and type of infection. Two situations should be treated by topical treatements: limited impetigo and furonculosis. The two topical antibiotics used preferentially are mupirocine and fucidic acid. Soon, a third topical antibiotic, reptamuline will complete these. For uncomplicated superficial skin infections justifying an oral antibiotic, amoxicillin-clavulanate offers the best guarantee of efficiency. Poor pharmacodynamic-pharmacokinetic must lead to not prescribe oral M penicillins. In case of allergy, a first-generation cephalosporin, a macrolide (if the susceptibility of the strain was checked) or pristinamycine (after 6 years of age) are acceptable alternatives. For dermohypodermitis bacterial antibiotic of choice remains amoxicillin-clavulanate through IV route, to be active against S. pyogenes but also S. aureus and anaerobic bacteria. The IV route is maintained until regression general signs and a relay orally by the same drug is then possible. For toxinic syndromes and necrozing fascitis clindamycin should be added to a beta-lactam because of its action on protein synthesis in particular reducing the toxins production.

Staphylococcus aureus (SA) isolates (n = 255) from outpatients with skin and soft-tissue infections were collected in 3 different areas in Norway. Group A streptococci (GAS, n = 68) were isolated from skin or pharyngotonsillar specimens from outpatients. Minimum inhibitory concentrations (MIC) of bacitracin, fusidic acid and mupirocin were tested using the E-test. Pulsed field gel electrophoresis (PFGE) patterns of fusidic acid-sensitive (FusS) and -resistant (FusR) SA were compared. All GAS isolates showed MIC of bacitracin of < or = 1.0 mg/l, of mupirocin of < or = 0.125 mg/l and of fusidic acid 1.0-4.0 mg/l. All the SA showed MIC of mupirocin < or = 0.5 mg/l and of bacitracin of > or = 2.0 mg/l, 91% with MIC > or = 16 mg/l. FusR was shown by 32.5% of the SA strains with similar prevalence rates in 3 different geographical areas of Norway. One particular PFGE pattern (type 1) was shown by 76% of the FusR SA. SA of type 1 belonged to phage group II and produced exfoliative toxins. Thus, the results demonstrated a high prevalence of FusR among SA causing skin infections and that this was mainly due to dissemination of clonally related FusR SA.

A new cream formulation of mupirocin developed to improve patient compliance was compared with systemic and topical antibiotics commonly used to treat primary and secondary skin infections. A mouse surgical wound model infected with Staphylococcus aureus or Streptococcus pyogenes was used. Topical treatment was applied at 4 and 10 h postinfection or oral treatment at a clinically relevant dose was administered 4, 8, and 12 h postinfection; treatments were continued three times daily for a further 3 days. Mupirocin cream was significantly more effective than (P < 0.01; two of eight studies) or not significantly different from (six of eight studies) mupirocin ointment in reducing bacterial numbers. Mupirocin cream was similar in efficacy to oral flucloxacillin but significantly more effective (P < 0.001) than oral erythromycin. It was also similar in efficacy to cephalexin against S. pyogenes but superior against S. aureus (P < 0.01). Mupirocin cream had a similar efficacy to fusidic acid cream against S. aureus but was significantly superior against S. pyogenes (P < 0.01). A hamster impetigo model infected with S. aureus was also used. Topical or oral treatment was administered at 24 and 30 h postinfection (also 36 h postinfection for oral therapy) and then three times daily for a further 2 days. On day 5, mupirocin cream was significantly more effective than mupirocin ointment in one study (P < 0.01) and of similar efficacy in the other two studies. Mupirocin cream was not significantly different from fusidic acid cream or neomycin-bacitracin cream, but it was significantly superior (P < 0.01) to oral erythromycin and cephalexin. Mupirocin cream was as effective as, or superior to, oral and other topical agents commonly used for skin infections.

The aim of the present post marketing study was to study the safety and efficacy of supirocin-B ointment (mupirocin 2% + betamethasone dipropionate 0.05%) in the treatment of infected dermatoses. For this purpose physicians from different parts of India were requested to keep the clinical records prospectively as per a specially designed proforma over a follow-up period of 7 days, whenever they prescribed supirocin-B ointment (mupirocin 2% + betamethasone dipropionate 0.05%) for local application, three times a day, to their patients having either primary infection complicated by dermatoses or dermatoses infected secondarily. From the analysis of 251 clinical records contributed by 27 physicians, it was evident that in clinical practice, supirocin-B ointment (mupirocin 2% + betamethasone dipropionate 0.05%) was found to be safe and very effective by physicians in the treatment of infected dermatoses in 94.8% of the patients. Similarly 92.4% of the patients reported more than 70% improvement in their symptoms after 7 days of treatment. No adverse effects were reported during the treatment period by any of the patients except worsening of skin lesions by one patient. Thus from this study, supirocin-B ointment (mupirocin 2% + betamethasone dipropionate 0.05%) seems to be safe and effective in the treatment of infected dermatoses.

Cutaneous infections with Staphylococcus aureus, Streptococcus pyogenes, and Pseudomonas aeruginosa are major complications of epidermolysis bullosa. Application of impermeable occlusive dressings over denuded skin colonized with these bacteria results in rapid multiplication and the hazard of severe pyoderma. Approaches to the prophylactic treatment of these infections during the long-term management of epidermolysis bullosa are considered.
