Staphylococcal scalded skin syndrome in neonates: an 8-year retrospective study in a single institution

The Clinical Characteristics and Antimicrobial Resistance of Staphylococcus aureus Isolated from Patients with Staphylococcal Scalded Skin Syndrome (SSSS) in Southwestern China

Staphylococcal scalded skin syndrome (SSSS) is a rare, toxin-mediated, desquamating bacterial infectious dermatosis. So far, data from Southwestern China is scarce. This study aimed to investigate the clinical characteristics of SSSS patients in our hospital, the relative proportion of methicillin-resistant Staphylococcus aureus (MRSA) in skin and soft tissue secretions, and the drug sensitivity of S. aureus to better assist dermatologists in the diagnosis and treatment of SSSS. We reviewed the demographic characteristics, clinical manifestations, treatment regimens, therapeutic efficacy, laboratory test results, drug sensitivity, and outcome data of 79 SSSS patients from January 2012 to December 2021. Statistical analysis was performed using t tests and chi-square tests. Among the 79 SSSS patients, MRSA was detected in 35 (44.3%) isolates: 34 community-acquired (CA)-MRSA (97.1%) and 1 hospital-acquired (HA)-MRSA. The SSSS incidence increased annually from 2012 to 2014 and then decreased gradually after peaking in 2015. All the isolates were sensitive to vancomycin, tigecycline, linezolid, moxifloxacin, levofloxacin, and ciprofloxacin; were completely resistant to penicillin; and had low sensitivity to clindamycin and erythromycin. Interestingly, the sensitivity of MRSA to tetracycline increased annually after 2015. The resistance rates to common drugs previously used to treat SSSS increased. These findings may accelerate diagnosis and improve empirical antibiotic use, suggesting that clinicians should prescribe drugs according to antimicrobial susceptibility.

Recurrent staphylococcal scalded skin syndrome in a 20-month old-A case report

We present a case of a 20-month-old child with a history of atopic dermatitis that exhibited recurrent erythematous-bullous lesions consistent with Staphylococcal Scalded Skin syndrome (SSSS). SSSS is an exfoliative toxin-mediated skin disorder most commonly found in children. In this paper, we discuss the importance of recognizing the clinical symptomatology and progressive nature of SSSS, particularly in patients with a history of atopic dermatitis, to ensure prompt treatment and resolution of the syndrome.

Associated Outcomes of Different Intravenous Antibiotics Combined with 2% Mupirocin Ointment in the Treatment of Pediatric Patients with Staphylococcal Scalded Skin Syndrome

Purpose

To compare treatment duration, influencing factors, and costs among intravenous antibiotic groups combined with 2% mupirocin ointment for treating staphylococcal scalded skin syndrome (SSSS).

Patients and Methods

Sex, age, onset days before admission, febrile status, white blood cell (WBC) count, and C-reactive protein (CRP) level were recorded as baseline characteristics for 253 included patients. The antibiotic sensitivity results were statistically compared by Cochran's Q test. Kruskal-Wallis tests were used to compare days and the total costs of hospitalization with different intravenous antibiotic applications. Mann-Whitney U-tests or Spearman's rank correlation tests were used for the univariate analysis. Finally, a multivariate linear regression model was employed to determine the variables with statistical significance.

Results

The sensitivity rates of oxacillin (84.62%), vancomycin (100%), and mupirocin (100%) were significantly higher than those of clindamycin (7.69%) (p<0.0001). The duration of intravenous ceftriaxone administration was significantly longer than that of amoxicillin-clavulanic acid, cefathiamidine, and cefuroxime (p<0.01). The total hospitalization costs for cefathiamidine were significantly higher than those for amoxicillin-clavulanic acid and cefuroxime (p<0.05). According to the multiple linear regression, ages ≥60 months old were correlated with shorter treatment duration (β=-1.48, [95% CI: -2.29, -0.66] for amoxicillin-clavulanic acid, and β=-1.44, [95% CI: -2.06, -0.83] for cefathiamidine, and β=-0.96, [95% CI: -1.58, -0.34] for cefuroxime) (all p<0.01). In multivariate analysis for cefathiamidine, higher WBC count (β=0.05, [95% CI: 0.01, 0.10], p<0.05) and CRP level (β=1.12, [95% CI: 0.14, 2.10], p<0.05) were associated with longer treatment course.

Conclusion

Oxacillin resistance was rare, and clindamycin resistance was high in pediatric patients with SSSS in our district. Intravenous amoxicillin-clavulanic acid and cefuroxime combined with topical mupirocin were favorable due to a shorter intravenous treatment course and lower costs. Younger age, elevated WBC count, and CRP levels could indicate a longer course of treatment with intravenous antibiotics.

Staphylococcal Scalded Skin Syndrome in Neonates: Case Series and Overview of Outbreaks

Skin and soft tissue infections caused by Staphylococcus aureus (S. aureus) cover a wide spectrum of diseases in neonates, including staphylococcal scalded skin syndrome (SSSS). We describe a representative case of SSSS in neonatal twins, which despite recurrence showed a mild clinical disease course. This case was part of a small outbreak on a neonatal intensive care unit and therefore exemplifies the existence of neonatal outbreaks with skin and soft tissue infections by S. aureus. Diagnosis is generally based on the clinical picture and response to antibiotics, but can be aided by histology and cultures. Sequence-based molecular techniques are available to evaluate typing and virulence of S. aureus in outbreak or surveillance settings. The pillars of treatment are antibiotics and supportive care. Methicillin resistance remains a topic of concern, especially in outbreak settings. Our overview of numerous outbreaks of neonatal S. aureus skin infections underlines the importance of outbreak management strategies, including screening to identify the source of the outbreak, and limiting exposure through hygienic measures and establishment of physical boundaries.

Recognizing and Managing Staphylococcal Scalded Skin Syndrome in the Emergency Department

ABSTRACT

Staphylococcal scalded skin syndrome is a superficial blistering disorder caused by exfoliative toxin-releasing strains of Staphylococcus aureus. Bacterial toxins are released hematogenously, and after a prodromal fever and exquisite tenderness of skin, patients present with tender erythroderma and flaccid bullae with subsequent superficial generalized exfoliation. The head-to-toe directed exfoliation lasts up to 10 to 14 days without scarring after proper treatment. Children younger than 6 years are predominantly affected because of their lack of toxin-neutralizing antibodies and the immature renal system's inability to excrete the causative exotoxins. The epidemiology, pathophysiology, and essential primary skin lesions used to diagnose staphylococcal scalded skin syndrome are summarized for the pediatric emergency medicine physician.

Antibiotic-resistant profile and the factors affecting the intravenous antibiotic treatment course of generalized Staphylococcal Scalded Skin Syndrome: a retrospective study

Background

Staphylococcal Scalded Skin Syndrome (SSSS) is caused by a special type of Staphylococcus aureus (S.aureus) which can produce exfoliative toxins. The generalized SSSS is recommended to be admitted and treated with intravenous antibiotics. However, there were limited reports on whether personal and clinical factors can have impacts on the duration of intravenous antibiotic application for pediatric patients with generalized SSSS.

We performed a study to assess the factors affecting intravenous antibiotic treatment course of SSSS patients. Additionally, the positive culture rates of S.aureus in different samples and the antibiotic-resistant profile were investigated.

Methods

Two hundred nineteen patients with generalized SSSS were included. Gender, age, area, season, maximum axillary temperature, white blood cell (WBC) count, C-reactive protein (CRP) level, types of intravenous antibiotics, and types of external antibiotics were recorded as the baseline. Simple linear regression was applied in the univariate analysis to determine the variables with statistical significance and then these variables were further examined in multivariate linear regression model. The positive culture rates of S.aureus in different sample sources were calculated and the drug sensitivity results were statistically compared by pairwise Chi square test.

Results

According to the multiple linear regression, older ages (β = − 0.01, p < 0.05) and external application of fusidic acid (β = − 1.57, p < 0.05) were associated with shorter treatment course, elevated leukocytes (β = 0.11, p < 0.001) and CRP level (β = 1.64, p < 0.01) were associated with longer treatment course. The positive culture rates of periorificial swabs, throat swabs, and blood samples were 54.55, 30.77, and 5.97% respectively. The resistant rates of levofloxacin (8.33%), gentamycin (8.33%), tetracycline (25%), oxacillin (8.33%), vancomycin (0%) were significantly lower than the ones of erythromycin (100%), trimethoprim-sulfamethoxazole (TMP/SMX) (83.33%), clindamycin (91.67%), penicillin G(100%) (p < 0.001).

Conclusion

Elevated leukocytes and CRP level indicated prolonged intravenous antibiotic treatment course. Older ages and external application of fusidic acid helped to reduce the treatment course. Compared with blood samples, the culture positive rates of S.aureus in periorificial and throat swabs were higher. Oxacillin and vancomycin resistance was rare and clindamycin resistance was common. Clindamycin monotherapy for SSSS should be avoided.

Demographic characteristics, clinical features, and optimal management of hospitalized patients with staphylococcal scalded skin syndrome

BACKGROUND/OBJECTIVES

Optimal management of staphylococcal scalded skin syndrome (SSSS) has not been established. Clindamycin may benefit patients via inhibition of ribosomal toxin production, but resistance patterns suggest penicillinase-resistant penicillins or cephalosporins should be the first line. Our goal was to describe demographic and clinical characteristics of SSSS patients at our institution, delineate bacterial resistance patterns, and examine outcomes of varying therapeutic strategies in SSSS.

METHODS

We performed a retrospective review of patients under the age of 18 with confirmed clinical SSSS diagnosis by the dermatology consult team at the University of North Carolina (UNC) Hospitals from January 2008 to April 2017. Median hospital and ICU length of stay (LOS) were compared using a Wilcoxon Rank Sum Test.

RESULTS

We found 59 SSSS patients. Coverage with clindamycin and vancomycin versus absence of that combination was associated with shorter ICU LOS. Although trending toward reduced hospital LOS, this was not significantly altered with the use of vancomycin and clindamycin after adjustment for multiple comparisons. Individual use of either clindamycin or vancomycin did not significantly alter overall hospital or ICU LOS. Among 24 patients with a pathogen identified on culture, 18 (75.0%) revealed resistance to clindamycin, and 2 (8.3%) revealed MRSA.

CONCLUSIONS

Clindamycin resistance is more prevalent in hospitalized SSSS patients compared to our pediatric outpatient population. The combination of vancomycin and clindamycin results in shorter ICU LOS. Individual use of clindamycin or vancomycin does not significantly reduce hospital or ICU LOS after adjustment for multiple comparisons.

Antibiotic Regimens and Associated Outcomes in Children Hospitalized With Staphylococcal Scalded Skin Syndrome

BACKGROUND

Controversy exists regarding the optimal antibiotic regimen for use in hospitalized children with staphylococcal scalded skin syndrome (SSSS). Various regimens may confer toxin suppression and/or additional coverage for methicillin-susceptible Staphylococcus aureus (MSSA) or methicillin-resistant S aureus (MRSA).

OBJECTIVES

To describe antibiotic regimens in hospitalized children with SSSS and examine the association between antistaphylococcal antibiotic regimens and patient outcomes.

DESIGN/METHODS

Retrospective cohort study of children hospitalized with SSSS using the Pediatric Health Information System database (2011-2016). Children who received clindamycin monotherapy, clindamycin plus MSSA coverage (eg, nafcillin), or clindamycin plus MRSA coverage (eg, vancomycin) were included. The primary outcome was hospital length of stay (LOS); secondary outcomes were treatment failure and cost. Generalized linear mixed-effects models were used to compare outcomes among antibiotic groups.

RESULTS

Of 1,259 children included, 828 children received the most common antistaphylococcal antibiotic regimens: clindamycin monotherapy (47%), clindamycin plus MSSA coverage (33%), and clindamycin plus MRSA coverage (20%). Children receiving clindamycin plus MRSA coverage had higher illness severity (44%) compared with clindamycin monotherapy (28%) and clindamycin plus MSSA (32%) (P =.001). In adjusted analyses, LOS and treatment failure did not differ among the 3 regimens (P =.42 and P =.26, respectively). Cost was significantly lower for children receiving clindamycin monotherapy and highest in those receiving clindamycin plus MRSA coverage (mean, $4,839 vs $5,348, respectively; P <.001).

CONCLUSIONS

In children with SSSS, the addition of MSSA or MRSA coverage to clindamycin monotherapy was associated with increased cost and no incremental difference in clinical outcomes.

Antimicrobial Resistance and Molecular Analysis of Staphylococcus aureus in Staphylococcal Scalded Skin Syndrome among Children in Korea

BACKGROUND

Staphylococcal scalded skin syndrome (SSSS) is a skin disease characterized by blistering and desquamation caused by exfoliative toxins (ETs) of Staphylococcus aureus (S. aureus). Although many countries show predominance of methicillin-susceptible S. aureus (MSSA), cases of methicillin-resistant S. aureus (MRSA) have been reported.

METHODS

Twenty-six children aged <15 years diagnosed with SSSS from January 2010 to December 2017 from three hospitals were included. S. aureus isolates from cases were analyzed for multilocus sequence types and ETs. Medical records were reviewed for clinical characteristics, treatment, and antimicrobial susceptibility patterns of S. aureus.

RESULTS

Among the 26 cases, mean age was 2.3 years. According to skin manifestations patients were classified as generalized (n = 10, 38.5%), intermediate (n = 11, 42.3%), and abortive (n = 5, 19.2%). Among all cases, 96.2% (25/26) were due to MRSA and the macrolide-resistance rate was 92.3% (24/26). ST89 (n = 21, 80.8%) was the most prevalent clone, followed by single clones of ST1, ST5, ST72, ST121, and ST1507. The eta gene was detected in one (3.8%) isolate which was MSSA. The etb gene was detected in 14 (53.8%) isolates, all of which were ST89. Nafcillin or first-generation cephalosporin was most commonly prescribed (n=20, 76.9%). Vancomycin was administered in four patients (15.4%) and clindamycin in nine patients (34.6%). Among MRSA cases, there was no difference in duration of treatment when comparing the use of antimicrobials to which the causative bacteria were susceptible or non-susceptible (9.75 vs. 8.07 days, P > 0.05).

CONCLUSION

S. aureus isolated from children with SSSS in Korea demonstrated a high prevalence of methicillin-resistant ST89 clones that harbored the etb gene. The predominance of MRSA suggests that antibiotics to which MRSA are susceptible may be considered for empirical antibiotic treatment in children with SSSS in Korea. Further studies on the role and effectiveness of systemic antibiotics in SSSS are warranted.

Staphylococcal scalded skin syndrome: An epidemiological and clinical review of 84 cases

BACKGROUND

Staphylococcal scalded skin syndrome (SSSS) is a toxin-mediated, blistering skin disorder that mainly affects infants and children. There is limited literature regarding pediatric SSSS. The purpose of this study was to describe the epidemiology, clinical features, and management of pediatric SSSS.

METHODS

Retrospective cohort study of pediatric patients with a clinical diagnosis of SSSS seen at the Hospital for Sick Children in Toronto, Ontario, Canada, from January 1994 to March 2016.

RESULTS

We included 84 patients with a clinical diagnosis of SSSS; 49/84 (58%) were male. Mean age of diagnosis was 3.1 ± 2.4 years. All patients presented with erythema and exfoliation, while 64/84 (76%) presented with vesicles/ bullae. Skin tenderness was the most common symptom, present in 68/84 (81%) subjects. Staphylococcus aureus was more commonly isolated from periorificial cultures than from bullae. Mean hospitalization was 4.7 ± 2.3 days. No difference was found in admission duration between children receiving clindamycin and those that did not (3.6 ± 2.2 vs 3.9 ± 2.34 days, P = .63). Skin debridement was the only risk factor leading to more complications and prolonged hospitalization (P = .03). Severe complications were seen in 4 (5%) cases, and no fatalities were observed.

CONCLUSIONS

Healthcare providers should be aware of SSSS and consider it in the differential diagnosis of infants and children with new onset erythema, exfoliation, and/or vesiculation. Suspected culprit pathogens were more often obtained from periorificial swabs; however, these isolates were not tested for exfoliative toxin to confirm causality. Antibiotic treatment should be guided by sensitivity testing. Addition of clindamycin as an anti-toxin agent had no effect on the duration of hospitalization, and this should be further investigated. Surgical debridement of the skin in patients with SSSS should be discouraged.

[Vesicles, pustules and vesiculopustules in early childhood]

Vesicles, pustules and vesiculopustules are frequent in newborns and infants and mostly self-limiting. In order to differentiate the rare life-threatening diseases and to therefore initiate the treatment in a timely manner, knowledge of vesicular, pustular and vesiculopustular dermatoses in early childhood is necessary.

Increasing Numbers of Staphylococcal Scalded Skin Syndrome Cases Caused by ST121 in Houston, Texas

BACKGROUND

The molecular epidemiology of Staphylococcus aureus strains causing staphylococcal scalded skin syndrome (SSSS) in the United States has not been described. We analyzed patient and S. aureus isolate characteristics associated with SSSS in children at Texas Children's Hospital.

METHODS

Patients with SSSS were identified by ICD9/10 codes and available S. aureus isolates were identified from an ongoing S. aureus surveillance study. Medical records were reviewed for 58 patients with available S. aureus isolates. Isolate analyses included PCR for agr group, pvl (lukSF-PV), tst, eta and etb, pulsed-field gel electrophoresis, multi-locus sequence typing and antimicrobial susceptibilities.

RESULTS

Cases of SSSS increased from 2.3/10,000 admissions in 2008 to 52.6/10,000 admissions in 2017 (P < 0.0001). The 58 study cases (57 methicillin-susceptible S. aureus, 1 MRSA) with isolates were from 2013 to 2017. The majority (88%) of isolates was of clonal cluster (CC) 121, agr group IV, pvl, tst and carried eta and/or etb and 26% were clindamycin resistant. Twelve ST121 isolates had high level resistance to mupirocin. Patients were treated with standard supportive care plus systemic antibiotics [clindamycin alone or in combination with another antibiotic (n = 44)]. One patient had a recurrent SSSS and one patient was transferred to a burn unit on day 3.

CONCLUSIONS

Cases of SSSS are increasing at our hospital. Most S. aureus strains isolated were of one CC, CC121 and carried eta and etb. Supportive care plus clindamycin was effective treatment. We speculate that CC121 was recently introduced to our region and is responsible for the increasing numbers of SSSS cases observed at Texas Children's Hospital.

Variation in Diagnostic Test Use and Associated Outcomes in Staphylococcal Scalded Skin Syndrome at Children's Hospitals

OBJECTIVES

The incidence of staphylococcal scalded skin syndrome (SSSS) is rising, but current practice variation in diagnostic test use is not well described. Our aim was to describe the variation in diagnostic test use in children hospitalized with SSSS and to determine associations with patient outcomes.

METHODS

We performed a retrospective (2011-2016) cohort study of children aged 0 to 18 years from 35 children's hospitals in the Pediatric Health Information System database. Tests included blood culture, complete blood count, erythrocyte sedimentation rate, C-reactive protein level, serum chemistries, and group A streptococcal testing. K-means clustering was used to stratify hospitals into groups of high (cluster 1) and low (cluster 2) test use. Associations between clusters and patient outcomes (length of stay, cost, readmissions, and emergency department revisits) were assessed with generalized linear mixed-effects modeling.

RESULTS

We included 1259 hospitalized children with SSSS; 84% were ≤4 years old. Substantial interhospital variation was seen in diagnostic testing. Blood culture was the most commonly obtained test (range 62%-100%), with the most variation seen in inflammatory markers (14%-100%). Between hospital clusters 1 and 2, respectively, there was no significant difference in adjusted length of stay (2.6 vs 2.5 days; P = .235), cost ($4752 vs $4453; P = .591), same-cause 7-day readmission rate (0.8% vs 0.4%; P = .349), or emergency department revisit rates (0.1% vs 0.6%; P = .148).

CONCLUSIONS

For children hospitalized with SSSS, lower use of diagnostic tests was not associated with changes in outcomes. Hospitals with high diagnostic test use may be able to reduce testing without adversely affecting patient outcomes.

Epidemiology of staphylococcal scalded skin syndrome in U.S. children

BACKGROUND

Staphylococcal scalded skin syndrome (SSSS) is a blistering dermatosis caused by exfoliative toxins released from Staphylococcus aureus.

OBJECTIVES

To describe the incidence, costs, length of stay (LOS), comorbidities and mortality of SSSS in U.S. children.

METHODS

The Nationwide Inpatient Sample 2008-2012 was analysed, including a 20% sample of U.S. hospitalizations and 589 cases of SSSS.

RESULTS

The mean annual incidence of SSSS was 7·67 (range 1·83-11·88) per million U.S. children, with 45·1 cases per million U.S. infants age < 2 years. In multivariable logistic regression models, SSSS was significantly associated with the following (shown as adjusted odds ratio and 95% confidence interval): female sex (1·12, 1·00-1·25), age (2-5 years: 13·31, 11·82-14·99; 6-10 years: 2·93, 2·35-3·66; 11-17 years: 0·44, 0·31-0·63); race/ethnicity (black: 0·69, 0·58-0·84) and season (winter: 2·04, 1·66-2·50; summer: 3·47, 2·86-4·22; autumn: 3·04, 2·49-3·70), with increasing odds over time (2010-2011: 2·28, 2·07-2·51; 2012: 2·98, 2·69-3·30). The geometric mean (95% confidence interval) LOS and cost of hospitalization for patients with vs. without SSSS were 3·2 (3·0-3·4) vs. 2·4 (2·4-2·5) days and $4624·0 ($4250-$5030) vs. $1872 ($1782·7-$1965). Crude inpatient mortality rates (with 95% confidence intervals) were similar for children with vs. without SSSS (0·33%, 0·00-0·79% vs. 0·36%, 0·34-0·39%). SSSS was associated with other infections, including in the upper respiratory tract and skin.

CONCLUSIONS

The prevalence of SSSS appears to be increasing over time, and was associated with a number of sociodemographic factors and other infections. Further studies are needed to confirm these findings and reduce rising rates of SSSS.

Rapid containment of nosocomial transmission of a rare community-acquired methicillin-resistant Staphylococcus aureus (CA-MRSA) clone, responsible for the Staphylococcal Scalded Skin Syndrome (SSSS)

Background

The aims of this study were to identify the source and the transmission pathway for a Staphylococcal Scalded Skin Syndrome (SSSS) outbreak in a maternity setting in Italy over 2 months, during 2014; to implement appropriate control measures in order to prevent the epidemic spread within the maternity ward; and to identify the Methicillin-Resistant Staphylococcus aureus (MRSA) epidemic clone.

Methods

Epidemiological and microbiological investigations, based on phenotyping and genotyping methods, were performed. All neonates involved in the outbreak underwent clinical and microbiological investigations to detect the cause of illness. Parents and healthcare workers were screened for Staphylococcus aureus to identify asymptomatic carriers.

Results

The SSSS outbreak was due to the cross-transmission of a rare clone of ST5-CA-MRSA-SCCmecV-spa type t311, exfoliative toxin A-producer, isolated from three neonates, one mother (from her nose and from dermatological lesions due to pre-existing hand eczema) and from a nurse (colonized in her nose by this microorganism). The epidemiological and microbiological investigation confirmed these as two potential carriers.

Conclusions

A rapid containment of these infections was obtained only after implementation of robust swabbing of mothers and healthcare workers. The use of molecular methodologies for typing was able to identify all carriers and to trace the transmission.

Childhood skin and soft tissue infections: new discoveries and guidelines regarding the management of bacterial soft tissue infections, molluscum contagiosum, and warts

PURPOSE OF REVIEW

Pediatric skin and soft tissue infections (SSTIs) constitute a significant number of office-based pediatric visits. With SSTIs on the rise, it is not only important to effectively treat the individual, but to do so appropriately and cost-consciously. In this article, we highlight new research related to the treatment of bacterial skin infections, molluscum contagiosum, and cutaneous warts, with the goal of guiding pediatricians in their practice against these common skin conditions.

RECENT FINDINGS

Recent data supports the use of topical antibiotics for noncomplicated impetigo. Systemic antibiotics covering gram-positive cocci are recommended for complicated cases of impetigo and deeper nonpurulent SSTIs. Localized purulent bacterial SSTIs can be treated with incision and drainage alone but more systemic involvement warrants treatment with systemic antibiotics covering Staphylococcus aureus species, especially community acquired methicillin-resistant S. aureus. For the treatment of molluscum contagiosum, topical cantharidin has a high satisfaction rate among patients and providers. Potassium hydroxide solution is a potentially effective and cheap form of molluscum contagiosum treatment. Imiquimod, however, has an unfavorable efficacy and safety profile as a therapy for molluscum contagiosum. Regarding warts, high-risk human papilloma virus strains have been detected in cutaneous warts in children.

SUMMARY

The high-risk human papilloma virus vaccine may play a role in treating pediatric cutaneous warts in the future, and topical squaric acid dibutylester may effectively treat recalcitrant warts. Finally, both molluscum contagiosum and warts have a high rate of resolution after an extended period of time without any intervention.

Epidermal exfoliation of over 95% after a burn in an 18-month-old boy: Case report and review of the literature

This report concerns an 18-month-old boy who presented with a 6% total body surface area scald. The subject of this report is unique in that he developed the largest exfoliation described in literature. After 3 days an epidermal exfoliation with the appearance of a deliberately inflicted scald developed. As the exfoliation progressed to over 95% total body surface area the suspicion of child abuse or neglect could be abandoned. The diagnosis Staphylococcal scalded skin syndrome was set, due to the finding of Staphylococcus aureus on swabs, the lack of mucosal engagement, and the patient's age. The boy's skin healed within 3 weeks. The few reports published are all case reports and most frequently described visually infected burns with smaller epidermal exfoliations, and clinically based exfoliation diagnosis. S. aureus often cause burn wound infections that can lead to complications caused by cross-infection. It is important for burn surgeons and intensive care specialists to be aware of the increased possibility of Staphylococcal scalded skin syndrome occurring in patients who have a reduced barrier to infection such as burn patients and also, that the diagnosis can be difficult to make.

A review of important skin disorders occurring in the posttransplantation patient

Hematopoietic stem cell transplantation continues to be the mainstay of treatment for many hematologic dyscrasias and malignancies, including acute leukemias, lymphomas, and aplastic anemia. There can be significant complications, however, and often these complications are manifested in the skin as an eruption. Common among these are acute and chronic graft-versus-host disease, erythema multiforme, Stevens-Johnson syndrome/toxic epidermal necrolysis, eruption of lymphocyte recovery, staphylococcal scalded skin syndrome, morbiliform drug eruptions, infections, and toxic erythema of chemotherapy. These entities can show significant clinical and histopathologic overlap, yet accurate distinctions among them are critical to initiating appropriate clinical interventions. In this review, we will discuss the key clinical and histopathologic findings in each entity as well as appropriate differential diagnostic entities.

Antibiotic sensitivity and resistance patterns in pediatric staphylococcal scalded skin syndrome

Historical resistance patterns often guide empiric antibiotic choices in staphylococcal scalded skin syndrome (SSSS), but little is known about the difference in susceptibility between SSSS and other childhood staphylococcal infections. A retrospective chart review of culture-confirmed cases of SSSS seen in the inpatient dermatology consultation service at the Children's Hospital of Philadelphia between 2005 and 2011 was performed. Most cases of SSSS at our institution are due to oxacillin-susceptible Staphylococcus aureus, and approximately half of the cases are due to clindamycin-resistant strains. Clindamycin and a penicillinase-resistant penicillin are suggested as empiric treatment for SSSS until culture susceptibility data are available to guide therapy.
