Abstract
UNLABELLED Impetigo is a common skin infection in children. The worldwide prevalence in children is estimated to be 12%, but this may be lower since high-income countries are under-represented. This research aims to evaluate the incidence, prevalence, and management of children with non-bullous impetigo (NBI) residing in Italy. This retrospective cohort study included children up to 14 years of age enrolled in the Pedianet database from January 2004 to June 2018. Events were identified searching ICD9-CM codes (684 and 694.3) and free text fields for a diagnosis of NBI reported during a primary care visit. Diagnoses were manually validated, and events registered within 30-days after the index date were considered follow-ups. Incidence (IR) and prevalence (PR) rates of NBI were stratified by sex, age group, and calendar year. Topical and systemic antibiotic treatments were grouped based on ATC codes. 15,136 NBI episodes occurred in a total cohort of 225,979 children. The overall IR of NBI was 9.5 per 1,000 person-years, and children aged 1-4 years had the highest IR (13.2 per 1,000 person-years). A significant decrease in NBI IR from 13 per 1,000 person-years in 2004 to 7.46 per 1,000 person-years in 2018 (p < 0.0001) was noted. Most of the episodes were treated; systemic antibiotics were preferred over topical. CONCLUSION The prevalence of NBI in children in Italy is less than one third than the global estimate and the trend in time is decreasing. Over prescriptions of systemic antibiotics pose a threat to the diffusion of antimicrobial resistance.

Abstract
BACKGROUND There is a lack of recently published data on impetigo presentation incidence and treatment practices in the routine Western European primary care setting. OBJECTIVES To investigate impetigo incidence, treatments and recurrence in primary care in the Netherlands. METHODS A retrospective, observational study. Electronic records of patients treated for impetigo in 2015 at 29 general practices in Utrecht and surrounds were reviewed. An episode of impetigo was defined as one or more patient-doctor contacts within 8 weeks of the index consultation. Within an episode, patient demographics and prescribing patterns were analysed including number of treatments, and the category and sequence of individual medicines. RESULTS A total of 1761 impetigo episodes were managed, with an incidence rate of 13.6 per 1000 person years. Impetigo peaked in summer. Most patients, the majority children, experienced a single episode (93%), and 25% had eczema as comorbidity. Topical antibiotics (primarily fusidic acid) were the most prescribed initial treatments (85%), followed by oral antibiotics (14%). Topical antibiotics were progressively used less over subsequent treatments, while there was an inverse increase in oral antibiotic use. Topical fusidic acid as the most common first line treatment seemed satisfactory as only 12% of initial treatments with this drug received further therapy. Repeat treatments generally occurred within 7 days. CONCLUSION This study of impetigo prescribing patterns in primary care highlighted that Dutch general practitioners were generally adherent to national treatment guidelines. Topical treatment, and if needed systemic small-spectrum antibiotic treatment, appeared satisfactory; these findings aid in antimicrobial stewardship.

Abstract
BACKGROUND Cutaneous bacterial infections are common in children and adults and frequently are caused by Staphylococcus aureus (S. aureus). Treatment failures with topical agents are not uncommon and have been shown to be secondary to bacterial resistance. OBJECTIVE To determine clinical and bacteriological efficacy of retapamulin ointment 1% in treatment of patients with cutaneous bacterial infections caused by methicillin-resistant S. aureus (MRSA) and other bacteria. METHODS Prospective, nonrandomized, uncontrolled, open label, single center trial conducted between April 2008 and November 2012 that evaluated efficacy of retapamulin ointment 1% in the treatment of impetigo, folliculitis, and other minor soft tissue infections in children and adults. Fifty patients, who presented to a dermatology outpatient clinic and were clinically diagnosed with impetigo, folliculitis, or minor soft tissue infection suitable for treatment with a topical antibiotic, were screened. Thirty-eight patients were enrolled and received treatment: topical retapamulin ointment 1% twice daily for 5 days. Seven patients were MRSA positive and qualified for the primary efficacy population. One patient withdrew due to an adverse event. Clinical and microbiological exams were performed at baseline and follow-up 5 to 7 days later to assess clinical, microbiological, and therapeutic responses. Primary outcome was clinical response at follow-up in primary efficacy population with MRSA isolated as the baseline pathogen. Secondary outcomes included clinical, microbiologic, and therapeutic responses in patients who were culture positive for any species of bacteria. RESULTS Clinical response at follow-up in the primary efficacy population (MRSA-positive patients) was not sufficiently powered to demonstrate significance; however, outcomes were excellent, with 7 of 7 patients demonstrating clinical success (5 of 7) or clinical improvement (2 of 7) at follow-up. Barring lack of significance due to small total sample size for patients who were culture positive for any species of bacteria (n = 35), overall success rates were favorable for clinical, microbiologic, and therapeutic responses with values of 66%, 97%, and 69%, respectively. Adverse events (AEs) were mild or moderate in severity. No serious AEs were reported. CONCLUSION Safety profile appears favorable given the low number of AEs. Study design limits conclusions that can be drawn. Nevertheless, this study supports use of topical retapamulin 1% ointment in treatment of cutaneous bacterial infections, particularly those caused by S. aureus, including MRSA.

Abstract
Background From around the year 2000, Northern Europe experienced a rise in impetigo caused by Staphylococcus aureus resistant to fusidic acid. A single clone of S. aureus was found to be the bacterial pathogen involved in the impetigo outbreak in Norway, Sweden, the UK and Ireland, termed ‘the epidemic European fusidic acid-resistant impetigo clone’ (EEFIC). We have followed the incidence of impetigo during the years 2001–2012 based on all patients in general practice in the island community of Austevoll, Western Norway. We previously reported a marked decline of impetigo incidence in Austevoll, from 0.0260 cases per person-year in 2002 to 0.0038 in 2009. This article explores indications of an end to the impetigo epidemic caused by the EEFIC clone. Methods: All four general practitioners (GPs) in the community (mean population = 4400) were asked to diagnose impetigo in a uniform way and to take bacterial specimens from all impetigo cases. Phenotypic characteristics of specimen bacteria were determined for the whole period and molecular analyses were performed on isolates in the period 2008–2012. Results: We observed a further decline in incidence of impetigo in Austevoll in the study period. The proportion of fusidic acid-resistant S. aureus isolates decreased during the period 2002–2012, with a mean of 80% in the epidemic years of 2002–2004, 55% in 2005–2009, and 6% in 2010–2012. In total, 44 S. aureus isolates from impetigo were subject to molecular analyses in the period 2008–2012, and 11 were found to be related to the EEFIC. All EEFIC isolates were found in 2008–2009, with no new isolates in 2010–2012. Conclusion: There is an apparent end to the impetigo epidemic related to the EEFIC in this population in Western Norway.

Abstract
Impetigo is a common cutaneous infection that is especially prevalent in children. The prevalence of colonization and infection with resistant strains is continually increasing, forcing clinicians to reevaluate treatment strategies. Newer topical agents are effective in treating infections with resistant strains and may help minimize resistance and adverse effects from systemic agents. Use of topical disinfectants to decrease colonization is an important adjunctive measure. Physicians should be aware of local resistance patterns in impetigo to help guide therapy.

Abstract
To clarify the prevalence of skin disorders among dermatology patients in Japan, a nationwide, cross-sectional, seasonal, multicenter study was conducted in 69 university hospitals, 45 district-based pivotal hospitals, and 56 private clinics (170 clinics in total). In each clinic, information was collected on the diagnosis, age, and gender of all outpatients and inpatients who visited the clinic on any one day of the second week in each of May, August, and November 2007 and February 2008. Among 67,448 cases, the top twenty skin disorders were, in descending order of incidence, miscellaneous eczema, atopic dermatitis, tinea pedis, urticaria/angioedema, tinea unguium, viral warts, psoriasis, contact dermatitis, acne, seborrheic dermatitis, hand eczema, miscellaneous benign skin tumors, alopecia areata, herpes zoster/postherpetic neuralgia, skin ulcers (nondiabetic), prurigo, epidermal cysts, vitiligo vulgaris, seborrheic keratosis, and drug eruption/toxicoderma. Atopic dermatitis, impetigo, molluscum, warts, acne, and miscellaneous eczema shared their top-ranking position in the pediatric population, whereas the most common disorders among the geriatric population were tinea pedis, tinea unguium, psoriasis, seborrheic dermatitis, and miscellaneous eczema. For some disorders, such as atopic dermatitis, contact dermatitis, urticaria/angioedema, prurigo, insect bites, and tinea pedis, the number of patients correlated with the average high and low monthly temperatures. Males showed a greater susceptibility to some diseases (psoriasis, erythroderma, diabetic dermatoses, inter alia), whereas females were more susceptible to others (erythema nodosum, collagen diseases, livedo reticularis/racemosa, hand eczema, inter alia). In conclusion, this hospital-based study highlights the present situation regarding dermatological patients in the early 21st century in Japan.

Abstract
OBJECTIVES From around year 2000, impetigo caused by fusidic acid-resistant Staphylococcus aureus was observed in countries of Northern Europe. The bacteria were found to represent a clone, the epidemic European fusidic acid-resistant impetigo clone (EEFIC). This study reports longitudinal data on the incidence and bacteriology of impetigo in a Norwegian island community during the years 2001-09. PATIENTS AND METHODS All encounters with general practitioners regarding impetigo were registered. Bacterial swabs were taken in a high percentage of cases. Annual incidence was calculated. Phenotypic characteristics of the bacteria were determined for the whole period, and in 2008 and 2009 we also performed PFGE and spa typing. RESULTS Outbreaks of impetigo were observed in 2002, 2003 and 2004, but since then the incidence decreased greatly. S. aureus was cultured from the impetigo site in the majority of cases. The proportion of S. aureus isolates resistant to fusidic acid decreased from 80% in 2002-04 to 45% in 2008-09. For 28 S. aureus isolates analysed by molecular methods in 2008-09, we found that nearly all cases of fusidic acid resistance were due to the presence of the EEFIC. CONCLUSIONS S. aureus resistance to fusidic acid in relation to impetigo is now less frequent in this population than at the start of the century. At present, most S. aureus bacteria resistant to fusidic acid in impetigo belong to the EEFIC.

Abstract
A rise in community-onset Staphylococcus aureus infections has been observed in European countries. To ascertain secular trends of S. aureus infections in primary healthcare in Denmark, we conducted this register-based study in the North Denmark region, during the period 1997-2008. We identified all skin and mucosa specimens obtained by general practitioners and all prescriptions for the preferred oral anti-staphylococcal antibiotic, dicloxacillin. Repeat observations within a 12-month period were excluded prior to the calculation of age and gender standardised incidence rates per 100,000 person-years. We included 108,758 specimens, of which 42,778 (39%) yielded S. aureus. The annual incidence rate of specimens doubled during the study period, reaching 2,399 in 2008. The overall rate of S. aureus isolates increased 2-fold to a stable rate at about 850, but for isolates from children and for impetigo specimens, the increase was steeper, with a peak in 2002. A total of 156,462 dicloxacillin prescriptions had been redeemed and the annual prescription rate increased 2.5-fold, peaking at 3,714 in 2007. In conclusion, the annual rates of specimens, S. aureus infections and dicloxacillin prescriptions more than doubled in primary healthcare during the 12-year study period. A major impetigo epidemic and calls for antibiotic stewardship with increased utilisation of specimens were contributing factors.

Abstract
Scabies and pyodermas are two of the commonest skin infections in tropical settings. They affect large numbers of people, particularly children, and account for a large burden of disease for peripheral health care teams. Despite this there have been significant advances in our knowledge of these diseases, their impact and their management. However there is a need to evaluate these developments in this specific setting, tropical health and in the context of communities with limited resources. This section will describe these advances and the challenges that remain.

Abstract
Retapamulin is a new topical pleuromutilin antibiotic for the treatment of skin and skin-structure infections, including impetigo. In vitro studies indicate that retapamulin has a unique mode of action that minimizes the potential for target-specific cross-resistance with other antibacterials and a limited potential for resistance development. Its spectrum of activity includes the most likely causative pathogens Staphylococcus aureus and Streptococcus pyogenes. In the Global Surveillance Program, retapamulin was highly active in vitro, including against strains of S. aureus resistant to methicillin, mupirocin or fusidic acid. In clinical studies, retapamulin was noninferior to fusidic acid and oral cefalexin, achieving per-pathogen success rates of 86-99%. Topical retapamulin has a good safety profile and is associated with high patient compliance.

Abstract
For this What's new in clinical dermatology?, I have selected some important publications mainly in the field of the infectious dermatosis and drugs allergy. The Chikungunya virus which is responsible of several epidemics since 2005 seems to be a virus with a cutaneous tropism. Sexually transmitted diseases are still a public health problem and we shall review the situation for syphilis, lymphogranuloma venereum and the new dynamic profile of HIV in France. Lyme disease has been the subject of consensus conference in France and in the United States. Original clinical presentations in relation with infectious agent will be also presented. We shall give a large place to what I call the toxidermatology. During the year 2007, the role of gadolinium in the nephrogenic systemic fibrosis has been confirmed, many publications have reported the side effects of biotherapies on the skin and we shall emphasize the paradoxical of some of them. Hypersensitivity syndrome and notably the controversial role of viral reactivations has been reported. The relationship between psoriasis and metabolic syndrome or cardiovascular risks has been discussed since 2006. New clinical features have been described and will be presented during this session.

Abstract
The objective of this study was to review the epidemiological patterns of acute post-streptococcal glomerulonephritis (APSGN) in a pediatric population. We compared incidence, pathogenesis, clinical presentation and outcomes in two APSGN pediatric patient cohorts in northeastern Florida. Retrospective medical records were reviewed of children who were admitted to our institution with a diagnosis of APSGN. Patients admitted between 1999 and 2006 (recent cohort) were compared with a previously reported cohort of patients admitted between 1957 and 1973 (earlier cohort). The recent cohort comprised 45 children with APSGN of whom 87% were male and 13% were female; the median age was 7 years, and there was an average incidence of 6.4 patients per year. The earlier cohort comprised 153 children with APSGN of whom 62% were male and 38% were female; the median age 4.25 years, and there was an average incidence of 10.9 patients per year. The recent cohort was predominantly White-American (62%) and the earlier cohort predominately African American (87%). In the recent cohort, 64% of patients had antecedent pharyngitis, and in the earlier cohort, 66% of patients had antecedent pyoderma. In the recent cohort, 11% of APSGN cases occurred between August to October, and in the earlier cohort, 50% occurred during these months. In the recent cohort, symptoms of APSGN at presentation were milder and all cases recovered, but in the earlier cohort two deaths (1.3% mortality) were reported. In conclusion, there has been a decline in the incidence and severity of APSGN at our institute in recent decades. Pharyngitis has replaced impetigo as the predominant cause of APSGN. The etiological agent for impetigo has changed over the last decade, which has impacted the incidence, racial distribution, seasonal variation and severity of APSGN.
