Background: It is unknown whether posttraumatic stress disorder (PTSD) is associated with incident infections. This study's objectives were to examine (1) the association between PTSD diagnosis and 28 types of infections and (2) the interaction between PTSD diagnosis and sex on the rate of infections., Methods: The study population consisted of a longitudinal nationwide cohort of all residents of Denmark who received a PTSD diagnosis between 1995 and 2011, and an age- and sex-matched general population comparison cohort. We fit Cox proportional hazards regression models to examine associations between PTSD diagnosis and infections. To account for multiple estimation, we adjusted the hazard ratios (HRs) using semi-Bayes shrinkage. We calculated interaction contrasts to assess the presence of interaction between PTSD diagnosis and sex., Results: After semi-Bayes shrinkage, the HR for any type of infection was 1.8 (95% confidence interval: 1.6, 2.0), adjusting for marital status, non-psychiatric comorbidity, and diagnoses of substance abuse, substance dependence, and depression. The association between PTSD diagnosis and some infections (e.g., urinary tract infections) were stronger among women, whereas other associations were stronger among men (e.g., skin infections)., Conclusions: This study's findings suggest that PTSD diagnosis is a risk factor for numerous infection types and that the associations between PTSD diagnosis and infections are modified by sex.

BackgroundIn the Netherlands, obstacle, mud and survival runs are increasingly popular. Although outbreaks of gastroenteritis have been reported following these events, associated health risks have not been systematically assessed.AimTo investigate the incidence of acute gastrointestinal infections (AGI), skin infections (SI) and respiratory infections (RI) among obstacle run participants, as well as risk factors.MethodsBetween April and October 2017, we conducted a retrospective cohort study among 2,900 participants of 17 obstacle runs in the Netherlands. Demographic, symptomatic and behavioural data were collected from participants via an online questionnaire 1 week after participation in an obstacle run. Stool specimens were obtained from respondents for microbiological tests. Adjusted relative risks (aRR) and 95% confidence intervals (CI) using multilevel binomial regression analysis were calculated.ResultsOf 2,646 respondents (median age: 33 years; 53% male), 76 had AGI after the obstacle run; ingesting mud was associated with AGI (aRR: 1.7; 95% CI: 1.2-4.9) and 38 respondents had AGI during or in the week before the obstacle run. Overall, 103 respondents reported SI and 163 RI. Rinsing off in a hot tub was associated with SI (aRR: 2.2; 95% CI: 1.7-2.8). Of 111 stool specimens, 13 tested positive for six different pathogens. No clusters were found.ConclusionThe reported incidence of AGI, SI and RI was low. Risk of these infections could be decreased by informing participants on preventive measures, e.g. showering vs rinsing in the hot tub, avoiding ingesting mud and not participating with symptoms of AGI.

Background: Hospitalisation with skin infection in Western Australian (WA) Aboriginal children is common, with the highest rates in infants and children from remote WA., Objective: We aimed to quantify infant, maternal, and sociodemographic risk factors for skin infection hospitalisation in WA children, focussing on Aboriginal children aged <17 years., Methods: We conducted a retrospective population-based cohort study with linked perinatal and hospitalisation data on WA-born children (1996-2012), of whom 31 348 (6.7%) were Aboriginal. We used Cox regression to calculate adjusted hazard ratios and associated population attributable fractions (PAFs) for perinatal factors attributed to first hospitalisation with skin infection. To identify specific risk factors for early-onset infection, we further restricted the cohort to infants aged <1 year., Results: Overall, 5439 (17.4%) Aboriginal and 6750 (1.5%) non-Aboriginal children were hospitalised at least once with a skin infection. Aboriginal infants aged <1 year had the highest skin infection hospitalisation rate (63.2 per 1000 child-years). The strongest risk factors in Aboriginal children aged <17 years were socio-economic disadvantage, very remote location at birth, and multi-parity (≥3 previous pregnancies) accounting for 24%, 23%, and 15% of skin infection hospitalisations, respectively. Other risk factors included maternal age <20 years, maternal smoking during pregnancy, and low birthweight., Conclusions: We have quantified the relative influence of perinatal risk factors associated with skin infection hospitalisations in WA children, providing measures indicating which factors have the potential to reduce the most hospitalisations. Our evidence not only supports existing calls for substantial government investment in addressing underlying social and environmental barriers to healthy skin in WA Aboriginal children but also identifies potential areas to target health promotion messaging at individuals/families on maternal smoking during pregnancy and skin hygiene for families., (© 2019 John Wiley & Sons Ltd.)

Introduction: Individuals infected with the human T-cell lymphotropic virus type 1 (HTLV-1) commonly present skin lesions, which may be a warning sign for the diagnosis of infection. This study describes the most prevalent skin manifestations in HTLV carriers attended at the clinic of Núcleo de Medicina Tropical (NMT) of the Universidade Federal do Pará (UFPA) in Belém, Pará, Brazil., Methods: This is a study of a series of cases of patients infected with human T-cell lymphotropic virus types 1 and 2 (HTLV-1/2) treated at NMT UFPA between 1999 and 2016. A descriptive analysis of data was applied., Results: Among 788 surveyed medical records in the service, 15.10% (n = 119) were referred to the dermatology clinic. From the series of cases that presented with skin lesions, 66.39% were female and 33.61% were male, and the average age of this group was 48 years. There was a predominance of patients with noninfectious inflammatory manifestations (64.2%), followed by infectious ones (24.6%), and 1.58% with lymphoproliferative diseases. As for the group of lesions, 45.26% of the erythematous-squamous type were observed, followed by dyschromia (24.21%), and eczematous (14.74%). One patient with a diagnosis of adult T-cell leukemia/lymphoma, another with parapsoriasis, and four with infective dermatitis are highlighted., Conclusion: Skin disorders in the HLTV positive patient are important causes of referral to the dermatologist with etiological and skin lesions groups diversity. In the series of cases studied, lymphoproliferatives diseases and infective dermatitis associated with HTLV-1 were presented as a challenge for the diagnosis and clinical management of these patients., (© 2019 The International Society of Dermatology.)

Objective: To identify the prevalent skin disorders among primary school children, awareness of its risk factors and to assess the socio-demographic determinants associated with their development., Methods: The cross-sectional observational study was conducted in September-December 2016 comprising children from six public and private schools in Wadi Al Dawaser region of Eastern Saudi Arabia. A self-generated self-administered questionnaire was sent through the children to be filled up by their parents. Details on sociodemographic and skin dermatoses conditions were collected. Data were analyzed using SPSS 16.., Results: Of the 710 students approached, 499(70.2%) responded. Of them, 151(30.2%) were boys and 348(69.7%) were girls. The overall mean age was 10.3}1.4 years (range: 3-15 years). The overall prevalence of skin disorders was 118(23.6%). Allergic dermatoses 11(11.3%) and eczema 4(11.8%) were the commonest conditions. Lichen planus 6(5%), acne 9(7.6%), allergic rashes 4(3.3%), and psoriasis 3(2.5%) were also recorded. Sociodemographic and hygiene factors were significantly associated with the disease (p<0.05 each)., Conclusions: A high prevalence of skin disorders was encountered among primary school children in the region studied.

Background: Community Acquired Methicillin Resistant Staphylococcus aureus (CA-MRSA) rates have been increasing worldwide and contribute to a growing "global health security threat" as reported by the WHO. Our group previously reported an overall rate of 7% in CA-MRSA upper extremity infections between 2004-2009 at the Auckland Regional Hand Unit. This fell below the Center for Disease Control (CDC) recommendation for empiric antimicrobial cover once local rates exceed 10-15%. We examined prevalence and characteristics of CA-MRSA upper extremity infections in our region over a subsequent 5-year period. Methods: One thousand two hundred and fifty-two patients with upper extremity infections requiring operative management between 2011 and 2015 inclusive were included in this study. Associated clinical characteristics were recorded including ethnicity, cultured organisms, antibiotic sensitivities, infection rate, and treatment practice. Results: One hundred and fifty (12%) of patients had culture positive CA-MRSA upper extremity infections. There was an increasing annual trend. Of note, rates of CA-MRSA in the Maori and Pacific Island ethnic subpopulations exceeded 15% in 2014 and 2015. Susceptibilities, associated factors and patient demographics are reported. Conclusions: Our unit enjoys significantly lower rates of CA-MRSA upper extremity infections than has been reported internationally. However, trends are increasing relative to our prior 6-year report, and the threshold for empiric treatment has been met within the Maori and Pacific Island ethnic subpopulations. This evolving threat is also highlighted by increasing cases of multi-drug resistant CA-MRSA. Evolving regional guidelines for empiric coverage of CA-MRSA among high-risk ethnic subpopulations identified by this study are underway.

Background: Patients with moderate-to-severe atopic dermatitis (AD) have increased infection risk, including skin infections and systemic infections. Immunomodulators (e.g., anti-tumor necrosis factors, anti-interleukin [anti-IL]-23, anti-IL-17, Janus kinase inhibitors) increase risk of infections. Dupilumab (a monoclonal antibody blocking the shared receptor component for IL-4 and IL-13) is approved for inadequately controlled moderate-to-severe AD and for moderate-to-severe eosinophilic or oral corticosteroid-dependent asthma., Objective: The aim was to determine the impact of dupilumab on infection rates in patients with moderate-to-severe AD., Methods: This analysis pooled data from seven randomized, placebo-controlled dupilumab trials in adults with moderate-to-severe AD. Exposure-adjusted analyses assessed infection rates., Results: Of 2932 patients, 1091 received placebo, 1095 dupilumab 300 mg weekly, and 746 dupilumab 300 mg every 2 weeks. Treatment groups had similar infection rates overall per 100 patient-years (placebo, 155; dupilumab weekly, 150; dupilumab every 2 weeks, 156; dupilumab combined, 152), and similar non-skin infection rates. Serious/severe infections were reduced with dupilumab (risk ratio 0.43; p < 0.05), as were bacterial and other non-herpetic skin infections (risk ratio 0.44; p < 0.001). Although herpesviral infection rates overall were slightly higher with dupilumab than placebo, clinically important herpesviral infections (eczema herpeticum, herpes zoster) were less common with dupilumab (risk ratio 0.31; p < 0.01). Systemic anti-infective medication use was lower with dupilumab., Conclusions: Dupilumab is associated with reduced risk of serious/severe infections and non-herpetic skin infections and does not increase overall infection rates versus placebo in patients with moderate-to-severe AD. CLINICALTRIALS., Gov Identifiers: NCT01548404, NCT02210780, NCT01859988, NCT02277743, NCT02277769, NCT02260986, and NCT02755649.

Industrial hog operation (IHO) workers are at increased risk of carrying Staphylococcus aureus in their nares, particularly strains that are livestock-associated (LA) and multidrug-resistant. The pathogenicity of LA-S. aureus strains remains unclear, with some prior studies suggesting reduced transmission and virulence in humans compared to community-associated methicillin-resistant (CA-MRSA) S. aureus. The objective of this study was to determine the degree to which LA-S. aureus strains contracted by IHO workers cause disease relative to a representative CA-MRSA strain in a mouse model of skin and soft tissue infection (SSTI). Mice infected with CC398 LA-S. aureus strains (IHW398-1 and IHW398-2) developed larger lesion sizes with higher bacterial burden than mice infected with CA-MRSA (SF8300) (p < 0.05). The greatest lesion size and bacterial burden was seen with a CC398 strain that produced a recurrent SSTI in an IHO worker. The LA-S. aureus infected mice had decreased IL-1β protein levels compared with CA-MRSA-infected mice (p < 0.05), suggesting a suboptimal host response to LA-S. aureus SSTIs. WGSA revealed heterogeneity in virulence factor and antimicrobial resistance genes carried by LA-S. aureus and CA-MRSA strains. The observed pathogenicity suggest that more attention should be placed on preventing the spread of LA-S. aureus into human populations.

Objectives: The aim was to characterize the clinical features, outcomes, and strain diversity of laboratory-confirmed Streptococcus pyogenes (group A Streptococcus, GAS) infections among inpatients hospitalized at a tertiary level hospital in Brussels, Belgium, according to the patients' housing status (homeless vs. not homeless)., Methods: Between August 2016 and January 2018, all patients hospitalized with a laboratory-confirmed GAS infection were prospectively enrolled and risk factors were recorded. GAS strains were characterized using emm-typing and emm-clustering in both inpatients and outpatients. Analyses were performed according to homelessness status., Results: During the study period, 48% (28/58) of adults hospitalized with a GAS infection at the tertiary hospital were homeless. The estimated incidence rate was 100 times higher for homeless persons. Skin abscesses were more frequent in the homeless group (21.4% vs. 3.3%) and mortality was high (10.7%). Limited emm-type diversity was found in this group, with four emm-types (64, 77, 83, and 101) accounting for 76.1% of the infections, and the majority of these emm-types belonged to the D4 emm-cluster. Pooled analyses of inpatient and outpatient strains indicated lower diversity in the homeless group., Conclusions: The homeless are disproportionately affected by GAS and have a higher rate of abscesses and high mortality. The lower emm-type diversity and preferential infection with four emm-types likely reflects endemic circulation of GAS in this population. Preventive strategies are warranted in this fragile population., (Copyright © 2019 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Background: Skin lesions are very common among organ transplant recipients (OTR), particularly infections and tumors, because of the immunosuppressive state these patients are put in., Methods: 177 OTR were examined. Skin lesions were categorized into neoplastic, infectious, and inflammatory diseases., Results: The mean age of OTR was 52 years, the mean age at transplantation was 42.7 years, and kidney was the most common organ transplanted (72%). Skin lesions were found in 147 patients (83%). Cutaneous infections were seen in 106 patients (60%). Warts (30%) had the larger incidence and were associated with azathioprine (P = 0.026), cyclosporine (P = 0.006), and tacrolimus (P = 0.009). Superficial mycoses occurred in 16% of OTR, mostly onychomycosis, which was associated with tacrolimus (P = 0.040). Actinic keratosis (AK) occurred in 31% of patients and cutaneous tumors in 56%. Squamous cell carcinoma (SCC) was the most common tumor type affecting 36% of OTR (n = 64), with invasive SCC predominating over in situ SCC, whereas basal cell carcinoma (BCC) accounted for 17%. Both SCC and BCC were more numerous in patients' skin type I (P < 0.05). SCC was more frequent (36%) in combined kidney and liver recipients (P = 0.004), and BCC was associated with cyclosporine (P = 0.047). Inflammatory complications (acne, alopecia, hypertrichosis, and gingival overgrowth) were observed in 17.5% of patients., Conclusions: Organ transplant recipients must be regularly evaluated by dermatologists, who should be alert to the onset of infections and skin (pre)malignant diseases in these patients., (© 2018 The International Society of Dermatology.)

Genetic background and molecular characteristics of Staphylococcus aureus collected from patients with skin and soft tissue infections were studied in the North-Central region of Bangladesh from 2015 to 2016. Among 430 clinical isolates, methicillin-resistant S. aureus (MRSA) accounted for 31% having SCCmec type IV (73%) and V (14%), and belonged mostly to coagulase (coa) genotypes IIa, IIIa, IVb, and XIa, while dominant coa type in methicillin-susceptible S. aureus (MSSA) was IIIa, followed by Va, IIa, and VIa. Panton-Valentine Leukocidin genes (pvl) were detected at higher rate in MSSA (54%) than in MRSA (24%). Based on multilocus sequence typing, pvl-positive MRSA isolates were classified into clonal complex 88 (CC88) (ST88, ST2884, ST4345), CC6 (ST6, ST4350), and CC1 (ST1, ST772), while pvl-negative MRSA into CC5, CC22, CC80, CC121, and CC672. The pvl-negative ST80 MRSA isolates had SCCmec-IVa (agr-III/coa-XIc, etd/edinB-positive, fusB-negative), indicating that they belong to the novel CC80 clade related to the European community-acquired MRSA clone. Among MSSA, genotypes ST121/spa-t645/coa-Va and ST2884 (CC88)/spa-t2393/coa-IIIa were identified in both pvl-positive and negative isolates, and all the ST772 isolates harbored pvl. All the ST121 isolates had a variant of elastin-binding protein gene (ebpS-v) with internal 180-nucleotide deletion. The present study suggested that CC88 (ST88, ST2884) and ST772 are the putative dominant lineages of pvl-positive MRSA/MSSA, while novel CC80 clade is one of the main pvl-negative MRSA lineages distributed endemically in Bangladesh.

Background: Infectious skin disorders (ISDs) are commonly seen in pediatric emergency departments (PED), however the exact frequency is unknown. We provide an accurate evaluation of the incidence and characteristics of ISDs diagnosed in a PED from Buenos Aires, Argentina, over a 1-year period., Methods: Prospectively, descriptive study of children evaluated in the PED with ISDs during 2016. ISDs were analyzed on the basis of their incidence, patient demographics, seasonal variations, and hospitalization rates., Results: ISDs were diagnosed in 1680 (67.9%) of the skin consultations (M/F: 1.1; mean age: 4.4 ± 3.7 years). Bacterial infections were observed in 932 (55.5%) cases. Viral infections were seen in 604 patients (35.9%). Fungal and parasite skin infections were diagnosed in 33 (2%) and 111 (6.6%) children, respectively. The most frequent ISDs according to the etiology group were impetigo 377 (22.4%), varicella 397 (23.6%), tinea capitis 10 (0.6%), and scabies 109 (6.5%). A higher frequency of ISDs were reported during the summer (38.4%) and spring (38.2%) months. Bacterial skin infections were more frequent during the summer months, while viral skin infections were more prevalent during spring. Parasitic skin infections were diagnosed more frequently during the winter months. No differences were seen for mycotic skin infections. Hospitalization rate was 1% (all for bacterial skin infections)., Conclusion: Our data reveal the extremely high frequency of ISDs seen at the PED, underlying the need for closer cooperation between dermatologists and pediatricians., (© 2018 The International Society of Dermatology.)

Background/objectives: Injection drug use is one of the major public health problems in Iran. Injection drug use is associated with numerous negative health outcomes, such as blood-borne infections (HIV, HCV) and injection site skin infections (abscesses, cellulitis). The aim of this study was to determine prevalence of injection site skin infections and its associated risk factors among people who inject drugs (PWID) in Tehran, Iran., Methods: The cross-sectional study was conducted from March to August 2016 in Tehran province. A total of 500 PWID were recruited by convenience and snowball sampling from Drop-in Centers (DIC) in the South of Tehran. Our primary outcomes were self-report of ever having injection sites skin infections and receiving treatment for them. We first examined associations between individual variables and lifetime history of having injection site infections in bivariate analysis using the chi-square or Fisher's exact tests, as appropriate. Variables with P-value <.2 were included in a multiple logistic regression model., Results: Overall, 40% (CI95%: 30.3%, 52.2%) of participants reported ever having an injection site infection. In the multivariable model, those with low socioeconomic status (AOR = 2.4, P = .03), self-reported as HIV positive (AOR =1.6, P = .01), reporting more than 3 injections per day (AOR = 4.1, P = .03) and reuse of their own syringes (AOR = 8.5, P = .03) were more likely to have injection sites skin infections. PWID who used needle and syringe program (NSP) services were less likely to report injection site infections (AOR = 0.5, P = .04)., Conclusion: We have identified several risk factors for injection sites infections among PWID, including frequency of injection per day, reuse of their own syringes, not using NSP services, HIV status, socioeconomic status with skin infections in PWID. Prevention strategies to reduce skin infections should focus on high-risk injection behaviors and improving access to NSP services., (© 2018 Wiley Periodicals, Inc.)

To determine the burden of skin and soft tissue infections (SSTI), the nature of antimicrobial prescribing and factors contributing to inappropriate prescribing for SSTIs in Australian aged care facilities, SSTI and antimicrobial prescribing data were collected via a standardised national survey. The proportion of residents prescribed ⩾1 antimicrobial for presumed SSTI and the proportion whose infections met McGeer et al. surveillance definitions were determined. Antimicrobial choice was compared to national prescribing guidelines and prescription duration analysed using a negative binomial mixed-effects regression model. Of 12 319 surveyed residents, 452 (3.7%) were prescribed an antimicrobial for a SSTI and 29% of these residents had confirmed infection. Topical clotrimazole was most frequently prescribed, often for unspecified indications. Where an indication was documented, antimicrobial choice was generally aligned with recommendations. Duration of prescribing (in days) was associated with use of an agent for prophylaxis (rate ratio (RR) 1.63, 95% confidence interval (CI) 1.08-2.52), PRN orders (RR 2.10, 95% CI 1.42-3.11) and prescription of a topical agent (RR 1.47, 95% CI 1.08-2.02), while documentation of a review or stop date was associated with reduced duration of prescribing (RR 0.33, 95% CI 0.25-0.43). Antimicrobial prescribing for SSTI is frequent in aged care facilities in Australia. Methods to enhance appropriate prescribing, including clinician documentation, are required.

Purpose: The purpose was to determine significant predictors of treatment failure of skin and soft tissue infections (SSTI) in the inpatient and outpatient setting., Methods: A retrospective chart review of patients treated between January 1, 2005 to July 1, 2016 with ICD-9 or ICD-10 code of cellulitis or abscess. The primary outcome was failure defined as an additional prescription or subsequent hospital admission within 30 days of treatment. Risk factors for failure were identified through multivariate logistic regression., Results: A total of 541 patients were included. Seventeen percent failed treatment. In the outpatient group, 24% failed treatment compared to 9% for inpatients. Overweight/obesity (body mass index (BMI) > 25 kg/m 2 ) was identified in 80%, with 15% having a BMI >40 kg/m 2 . BMI, heart failure, and outpatient treatment were determined to be significant predictors of failure. The unit odds ratio for failure with BMI was 1.04 (95% [Cl] = 1.01 to 1.1, p = 0.0042). Heart failure increased odds by 2.48 (95% [Cl] = 1.3 to 4.7, p = 0.0056). Outpatients were more likely to fail with an odds ratio of 3.36., Conclusion: Patients with an elevated BMI and heart failure were found to have increased odds of failure with treatment for SSTIs. However, inpatients had considerably less risk of failure than outpatients. These risk factors are important to note when making the decision whether to admit a patient who presents with SSTI in the emergency department. Thoughtful strategies are needed with this at-risk population to prevent subsequent admission., (Published by Elsevier Inc.)

Objectives: Skin disorders are the most common health problems seen among HIV positive patients. It presents with a variety of manifestations which can cause significant morbidity. This study was aimed to assess the prevalence of common skin problems among children living with HIV/AIDS at Hawassa University Comprehensive Specialized Hospital, Hawassa, Ethiopia, 2017/2018. Hospital based cross-sectional study was conducted among 125 children living with HIV/AIDS who were recruited through simple random sampling techniques from February to April 2017. Pre-tested, structured questionnaires were used to collect the data., Result: Among a total of 125 study participants, 72 (57.6%) of the children were males and 97 (77.6%) were in the age range of 10-14 years. 90 (72%) of participants had different kinds of skin problems. Among those who had one kind of common skin infection, 53 (42.4%) were males. Viral skin infections that accounts 48 (53.3%), were the leading cause of skin infections followed by 43 (47.8%), 33(36.7%) and 22 (24.7%) fungal infections, inflammatory and bacterial skin infections respectively. Among all children who were taking ART, only 2.4% of the children had skin related side effects.

Background: Infections are one of the major causes of death in patients with advanced-stage mycosis fungoides (MF) or Sézary syndrome (SS). However, few recent data are available on the characteristics and risk factors of these infectious events., Objectives: To describe infectious events occurring in a cohort of patients with MF/SS, and to identify associated clinical and biological risk factors., Methods: A retrospective cohort study was performed to investigate infectious events and associated factors in patients diagnosed with MF (stage IB and beyond) or SS followed from May 2011 to May 2016 at the University Hospital of Bordeaux, France., Results: Seventy-one patients with complete follow-up were included. Eighty infectious events were recorded in 40 patients, including 28 skin and soft tissue infections and 25 cases of pneumonia. Opportunistic infections, which are usually associated with depleted cell-mediated immunity, were scarce (9%). In multivariate analysis, cardiac, renal or lung comorbidities [odds ratio (OR) 7·2, 95% confidence interval (CI) 3·3-15·9; P = 0·002], SS (OR 8·8, 95% CI 7·7-10·2; P = 0·037) and lymphocyte count < 0·5 × 10 9 cells L -1 (OR 6·4, 95% CI 1·5-27·4; P = 0·004) were significantly associated with a higher risk of infection., Conclusions: Opportunistic germs were rarely recorded, but their incidence was probably prevented by adequate prophylaxis (ongoing in 28% of patients). As in patients living with AIDS, pneumonias were frequent. On the other hand, bacterial cutaneous infections represent a specific pattern in patients with MF/SS. Patients with chronic organ failure, lymphocytopenia and SS should be considered as being at high risk for infectious events. Pneumococcal vaccination should be systematically recommended, and prophylaxis with co-trimoxazole and valaciclovir when the CD4 count is < 0·2 × 10 9 cells L -1 ., (© 2018 British Association of Dermatologists.)

Background: Renal transplant recipients (RTR), which are an increasing population, frequently suffer from post-transplant dermatological complications. Despite the well-established role of dermatologists in the outpatient care of these patients, no previous studies were found concerning dermatology consultations for hospitalized RTR., Objectives: To investigate the epidemiology of dermatological conditions presented by RTR during hospitalization and assess the impact of dermatology consultations performed in the hospital setting., Methods: Dermatology consultations requested for RTR admitted at a kidney transplantation referral hospital in Brazil over 36 consecutive months were retrospectively included., Results: 176 consultations were included. Infectious dermatoses prevailed (52.3%), followed by inflammatory diseases (14.2%), neoplasms (12.5%) and drug reactions (8.5%). Diagnostic agreement between requesting and consulting teams was 38.1%. Most consultations were motivated by common dermatological conditions, unrelated to admission diagnosis. There were some differences in comparison to previous studies including general inpatients, such as: larger proportion of infectious dermatoses and neoplasms, smaller proportion of inflammatory diseases, higher percentage of patients submitted to skin biopsy, smaller proportion of consultations managed with a single visit and higher probability of a systemic treatment being recommended in this population., Conclusion: Hospitalized RTR present distinct dermatological epidemiology and higher level of complexity, when compared to studies including general inpatients. Dermatology interventions during hospitalization may be beneficial in the multidisciplinary care of these patients, either contributing to the investigation of systemic conditions or providing relief for cutaneous comorbidities., (Copyright © 2018 AEDV.

This article covers the diagnosis and treatment of skin and soft tissue infections commonly encountered in the emergency department: impetigo, cutaneous abscesses, purulent cellulitis, nonpurulent cellulitis, and necrotizing skin and soft tissue infections. Most purulent infections in the United States are caused by methicillin-resistant Staphylococcus aureus. For abscesses, we emphasize the importance of incision and drainage. Nonpurulent infections are usually caused by streptococcal species and initial empiric antibiotics need not cover methicillin-resistant Staphylococcus aureus. For uncommon but potentially lethal necrotizing skin and soft tissue infections, the challenge is rapid diagnosis in the emergency department and prompt surgical exploration and debridement., (Copyright © 2018 Elsevier Inc.

Objective: The aim of this study was to compare the incidence of skin and soft tissue infections (SSTIs) across healthcare settings and analyze direct healthcare expenditures related to SSTIs in 2000 and 2012 in the United States., Methods: We performed a retrospective, cross-sectional analysis of nationally representative data from the Medical Expenditure Panel Surveys. Population-based incidence rates were examined for all healthcare settings that include inpatient visits, emergency department visits and ambulatory visits for SSTIs. The direct costs of healthcare services utilization were reported. Population-based prescribing rates for each antimicrobial class during ambulatory visits were compared., Results: A total of 2.4 million patients experienced an SSTI in 2000 compared to 3.3 million in 2012 (40% increase). From 2000 to 2012, the incidence of patients with at least one hospital visit for SSTIs increased 22%, ambulatory care visits increased 30%, and emergency department visits increased 40%. The incidence of SSTIs in children and adolescents declined 50% (from 150 to 76 per 10,000 person; RR = 0.51, 95% CI: 0.38-0.67; p<0.001) whereas SSTIs in older adults (> 65 years of age) increased almost 2-fold (from 67 to 130 per 10,000 person; RR = 1.94, 95% CI: 1.44-2.61; p<0.001). The annual incidence of SSTI in adults did not change significantly from 2000 to 2012 (from 84 to 81 per 10,000 person; RR = 0.96, 95% CI: 0.71-1.31; p = 0.41). The total estimated direct healthcare costs of SSTIs increased 3-fold from $4.8 billion in 2000 to $15.0 billion in 2012, largely driven by an 8-fold increase in ambulatory expenditures for SSTIs. Total population-based antimicrobial prescription rates for SSTIs increased 4-fold from 2000 to 2012 (from 59.5 to 250.4 per 10,000 person)., Conclusions: The highest healthcare utilization for SSTI treatment occurred in the ambulatory care setting and also accounted for the largest increase in overall direct expenditures from 2000 to 2012., Competing Interests: The authors have declared that no competing interests exist.

Background: Congenital ichthyoses (CIs) adversely affect quality of life (QOL) in patients. However, the effects of CIs on patient QOL have not been studied sufficiently., Objective: To investigate the association between disease severity and QOL in patients with harlequin ichthyosis (HI) and ichthyosis: syndromic forms (ISFs) METHODS: Clinical information of patients with HI and ISFs from 2010 to 2015 were obtained from 100 dermatology departments/divisions of principal institutes/hospitals throughout Japan. We examined the relationship between disease severity and QOL in patients with HI and ISFs. Patients who were aged 8 years or older and participated in a multicenter retrospective questionnaire survey in Japan were assessed by dermatology life quality index (DLQI, range of 0-30) and clinical ichthyosis score (range of 0-100)., Results: Netherton syndrome patients had a significantly higher risk of allergy to food or environmental allergens than patients with other phenotypes. Keratitis-ichthyosis-deafness (KID) syndrome patients showed a significantly higher risk of skin infections than patients with other phenotypes. Complete data on DLQI were obtained from 13 patients, whose median age was 21 (8-71) years. Nine patients were male, and 4 were female. Systemic retinoids were administrated to 2 of the 3 HI patients. The Spearman's correlation coefficient between the clinical ichthyosis score and DLQI was 0.611 (P < 0.05)., Conclusion: We confirmed that Netherton syndrome and KID syndrome patients have a higher risk of allergy to food or environmental allergens and of skin infections, respectively. QOL impairment correlates with disease severity in HI and ISFs patients., (Copyright © 2018 Japanese Society for Investigative Dermatology. Published by Elsevier B.V. All rights reserved.)

Background and Aims: Chronic skin and soft tissue infections (SSTI) among people who inject drugs (PWID) can lead to AA amyloidosis: a serious, yet neglected, multi-organ disease. We aim to synthesize findings on the epidemiology, risk factors, clinical outcomes, screening recommendations and challenges to treatment for AA amyloidosis among PWID., Methods: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). We searched the following bibliographic databases in July 2017: CINAHL Plus, Embase, Global Health, MEDLINE, PsycEXTRA, PsycINFO and SCOPUS. Studies were included if they investigated AA amyloidosis in PWID. Studies were not restricted to location, study type, year or language of publication. Study heterogeneity precluded meta-analysis; we present a narrative review of the literature., Results: Thirty-seven papers from eight countries met inclusion criteria. A total of 781 PWID are reported on, of whom 177 had AA amyloidosis. Where disease causality is established, it is attributed to chronic inflammation caused by injecting-related SSTIs. Most (88.7%) PWID with AA amyloidosis had SSTIs. The proportion of PWID with AA amyloidosis at post-mortem ranged from 1.6% (Germany) to 22.5% (Serbia). Biopsy studies reported from 5.26% (Portugal) to 50% (Germany) of AA amyloidosis in PWID with suspected or known kidney disease. Following diagnosis, the typical trajectory for PWID with AA amyloidosis was rapid deterioration of renal function requiring haemodialysis. Treatment difficulties, end-stage renal failure and premature death from sepsis were observed. Good outcomes, including reversibility of AA amyloidosis, are attributed to rapid treatment of the underlining inflammation and injecting cessation. Notably, given the population in question, no studies were published in addiction or harm reduction journals; most (92%) appeared in specialist nephrology and medical journals., Conclusion: There is strong evidence of an association between skin and soft tissue infections (SSTIs) and AA amyloidosis. Among people who inject drugs, injecting-related SSTIs are a significant cause of morbidity and premature mortality and there is evidence of increasing SSTI prevalence. Limitations in the literature make it difficult to estimate AA amyloidosis prevalence among people who inject drugs., (© 2018 Society for the Study of Addiction.)

With an incidence of 1 in 700 births, Down syndrome (DS) is not an uncommon condition. It is associated with various disorders of different organ systems. Serious disorders include cardiac defects and leukemia. With an onset during the newborn period, the latter does not always progress to classic myeloid leukemia (transient myeloproliferative disorder). Skin manifestations in newborns include pustules/vesiculopustules. In individuals with DS, such lesions should not only prompt suspicion for typical neonatal rashes and infections but also for transient myeloproliferative disorder. However, most dermatoses are benign. They essentially comprise disorders of keratinization that present as xerosis, keratosis pilaris, lichenification, and ichthyosis vulgaris. Also typical but not specific is the four-finger palmar crease (simian crease). Patients frequently develop folliculitides, which - due to elastolysis - subsequently progress to anetoderma. The known immune disturbance in DS patients explains the occurrence of autoimmune diseases such as alopecia areata and vitiligo. Typical skin conditions associated with DS include elastosis perforans serpiginosa, syringomas, milia-like calcinosis cutis, and multiple eruptive dermatofibromas., (© 2018 The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.)

Atopic dermatitis is a common chronic pruritic inflammatory skin disorder, characterized by an abnormal skin barrier, immune dysfunction, and an altered skin microbiome. Atopic dermatitis may be seen in conjunction with a variety of other skin disorders due to the complex pathogenesis of atopic dermatitis, involving genetic and environmental factors that are associated with immune dysfunction, barrier defects, and altered skin microbiomes. Skin disorders associated with atopic dermatitis include diseases sharing similar genetic origins like ichthyosis vulgaris, infectious diseases such as impetigo, and eczema herpeticum, in addition to the cutaneous autoimmune diseases, alopecia areata, and vitiligo. Atopic dermatitis is also often linked to such benign conditions as pityriasis alba and keratosis pilaris. This review discusses the cutaneous comorbidities of atopic dermatitis and their relationship via their occurrence in conjunction with atopic dermatitis., (Copyright © 2018 Elsevier Inc.

Introduction: Maintenance hemodialysis (HD) patients are potential transplant recipients. One of the most common cancers in the population of kidney recipients is skin neoplasm. Skin infections are also of a particular importance. In this population, especially in patients on the transplant waiting list, full dermatological examination, including dermatoscopy, should be carried out routinely., Materials and Methods: The research was comprised of 105 HD patients (57 men, 48 women) with a mean age of 60.8 (range 25-94) years. The patients' skin condition was assessed and a dermatoscopic examination was performed. We compared the incidence of skin diseases in the two subpopulations: HD patients (n = 89) and HD patients active on the transplant waiting list (n = 16)., Results: Bacterial, fungal, and viral infections in the group of HD patients occurred in 24.7%, 14.6%, and 6.7% of patients, respectively. In HD patients on the waiting list, bacterial skin diseases were reported in 12.5% of patients, and neither fungal nor viral infections were noticed. Malignant skin lesions and precancerous conditions, such as basal cell carcinoma and keratosis actinic, developed in 4.5% and 3.4% of the HD patients. These malignancies did not occur in HD patients on the waiting list. The results show proper qualification for transplantation in maintenance HD patients before the waiting list. In the group of dialysis patients, 67.4% required dermatological care, while in the HD waiting group only 12.5% required dermatological care., Conclusions: The presented results prove the necessity of performing dermatological examinations on HD patients. Some dermatological skin lesions, if not diagnosed and treated, could progress to cancer after organ transplantation., (Copyright © 2018 Elsevier Inc. All rights reserved.)

Background: Skin and soft tissue infections (SSTIs) are a leading cause of morbidity and mortality among people who inject drugs (PWID). International data indicate up to one third of PWID have experienced an SSTI within the past month. Complications include sepsis, endocarditis and amyloid A (AA) amyloidosis. AA amyloidosis is a serious sequela of chronic SSTI among PWID. Though there is a paucity of literature reporting on AA amyloidosis among PWID, what has been published suggests there is likely a causal relationship between AA amyloidosis and injecting-related SSTI. If left untreated, AA amyloidosis can lead to renal failure; premature mortality among diagnosed PWID is high. Early intervention may reverse disease. Despite the high societal and individual burden of SSTI among PWID, empirical evidence on the barriers and facilitators to injecting-related SSTI prevention and care or the feasibility and acceptability of AA amyloidosis screening and treatment referral are limited. This study aims to fill these gaps and assess the prevalence of AA amyloidosis among PWID., Methods: Care and Prevent is a UK National Institute for Health Research-funded mixed-methods study. In five phases (P1-P5), we aim to assess the evidence for AA amyloidosis among PWID (P1); assess the feasibility of AA amyloidosis screening, diagnostic and treatment referral among PWID in London (P2); investigate the barriers and facilitators to AA amyloidosis care (P3); explore SSTI protection and risk (P4); and co-create harm reduction resources with the affected community (P5). This paper describes the conceptual framework, methodological design and proposed analysis for the mixed-methods multi-phase study., Results: We are implementing the Care and Prevent protocol in London. The systematic review component of the study has been completed and published. Care and Prevent will generate an estimate of AA amyloidosis prevalence among community recruited PWID in London, with implications for the development of screening recommendations and intervention implementation. We aim to recruit 400 PWID from drug treatment services in London, UK., Conclusions: Care and Prevent is the first study to assess screening feasibility and the prevalence of positive proteinuria, as a marker for AA amyloidosis, among PWID accessing drug treatment services. AA amyloidosis is a serious, yet under-recognised condition for which early intervention is available but not employed.

Background and Aims: Patients with inflammatory bowel diseases are prone to cutaneous manifestations. The aim of this study was to investigate their prevalence, type and association to demographic and clinical factors., Methods: This was a cross-sectional study. Information relative to patients of a central Portuguese hospital with a definitive diagnosis of an inflammatory bowel disease, who were prospectively recruited, was collected., Results: The final cohort included 342 patients, 62% of whom had Crohn's disease and 38% had ulcerative colitis. Cutaneous extraintestinal manifestations were present in 44.4% of all patients; this prevalence was lower [14.9%] when excluding cutaneous manifestations secondary to nutrition deficiency or drugs. These skin lesions were classified as granulomatous [0.3%], reactive [4.4%], immunologically associated [10.5%] and secondary to nutritional deficiencies [6.4%] or to bowel-related therapy [29.5%]. Excluding those secondary to nutrition or drugs, cutaneous manifestations were significantly associated with females (odds ratio [OR] 3.210 [1.625-6.340], p = 0.001) and younger patients (OR 0.954 [0.924-0.985], p = 0.004). Additionally, their occurrence was related to patients up to 16 years (OR 13.875 [1.332-144.484], p = 0.028) among the Crohn's disease sub-cohort, whereas in the ulcerative colitis sub-cohort they were more likely to occur in patients with extensive colitis (OR 5.317 [1.552-18.214], p = 0.008)., Conclusions: Nearly half of the patients analysed had at least one cutaneous extraintestinal manifestation. The fact that certain lesions tend to be more common among patients with defined characteristics should alert the physicians and allow an early diagnosis and, when pertinent, a reference to dermatology.

Background: Diabetes mellitus (DM) is a major cause of illness and death in the United States, and diabetic patients are at increased risk for burn injury. We therefore sought to examine the impact of pre-existing DM on the risk of inpatient mortality and hospital acquired infections (HAI) among burn patients., Methods: Adult patients (≥18 years old) admitted from 2004 to 2013 were analyzed. Weighted Kaplan-Meier survival curves - adjusting for patient demographics, burn mechanism, presence of inhalation injury, total body surface area, additional comorbidities, and differential lengths of stay - were used to estimate the 30-day and 60-day risk of mortality and HAIs., Results: A total of 5539 adult patients were admitted and included in this study during the study period. 655 (11.8%) had a pre-existing DM. The crude incidence of HAIs and in-hospital mortality for the whole burn cohort was 8.5% (n=378) and 4.4% (n=243), respectively. Diabetic patients were more likely to be older, female, have additional comorbidities, inhalational injury, and contact burns. After adjusting for patient and burn characteristics, the 60-day risk of HAI among patients with DM was significantly higher, compared to non-diabetic patients (RR 2.07, 95% CI 1.28, 6.79). However, no significant difference was seen in the 60-day risk of mortality (RR 1.34, 95% CI 0.44, 3.10)., Conclusions: Pre-existing DM significantly increases the risk of developing an HAI in patients following burn injury, but does not significantly impact the risk of inpatient mortality. Further understanding of the immune modulatory mechanism of burn injury and DM is imperative to better attenuate the acquisition of HAIs., (Copyright © 2017 Elsevier Ltd and ISBI.

Background: People with diabetes may be at higher risk for acquiring infections through both glucose-dependent and biologic pathways independent of glycemic control. Our aim was to estimate the association between diabetes and infections occurring in primary care., Methods: Using the Newfoundland and Labrador Sentinel of the Canadian Primary Care Sentinel Surveillance Network, patients with diabetes ≥18 years between 1 January 2008 and 31 March 2013 were included with at least 1-year of follow-up. We randomly matched each patient with diabetes on the date of study entry with up to 8 controls without diabetes. Primary outcome was the occurrence of ≥1 primary care physician visits for any infectious disease. Secondary outcomes included primary visits for head & neck, respiratory, gastrointestinal, genitourinary, skin and soft tissue, musculoskeletal, and viral infections. Using multivariable conditional logistic regression analysis, we measured the independent association between diabetes and the occurrence of infections., Results: We identified 1779 patients with diabetes who were matched to 11,066 patients without diabetes. Patients with diabetes were older, had a higher prevalence of comorbidities, and were more often referred to specialists. After adjusting for potential confounders, patients with diabetes had an increased risk of any infection compared to patients without diabetes (adjusted odds ratio = 1.21, 95% confidence interval 1.07-1.37). Skin and soft tissue infections had the strongest association, followed by genitourinary, gastrointestinal, and respiratory infections. Diabetes was not associated with head and neck, musculoskeletal, or viral infections., Conclusion: Patients with diabetes appear to have an increased risk of certain infections compared to patients without diabetes.

Statistical data on the frequency of skin conditions in the Pomeranian region of Poland are limited in the field of pediatric dermatology, requiring a multidisciplinary approach to each patient. Dermatitis and skin allergies are the 10 most common pediatric conditions, with a prevalence of 20% among such chronic illnesses in developed countries. This analysis is limited to the recurrence of dermatologic diseases in the hospitalized pediatric population within the Pomeranian region for the purpose of future targeted education. Retrospective analysis included 282 participants over a 3-year period between 2013 and 2015, with admissions to the Department of Dermatology, Venereology, and Allergology at the Medical University of Gdansk. Diagnoses were obtained from the ward admission book and CliniNet database.

Purpose: Staphylococcus aureus is an important cause of infections in hospitalized neonates. Preterm or low birthweight infants are especially at risk to develop a S. aureus infection due to the immaturity of the immune system, length of hospital stay and invasive procedures. Exfoliative toxin (ET)-producing S. aureus is often responsible for neonatal infections, causing clinical manifestations such as staphylococcal scalded skin syndrome, characterized by both localized blisters or generalized exfoliation of the skin., Methods: We describe an outbreak due to an S. aureus strain producing ETA occurring in a local hospital in Northern Italy. Molecular typing of the isolates included spa typing and multilocus sequence typing. DNA microarray hybridization was also performed on one representative strain., Results: In the period from July 2013 to February 2014, 12 neonates presented with skin infections, mainly bullae or pustules. Cultures of skin swabs yielded methicillin-susceptible S. aureus (MSSA). By molecular typing, an epidemic strain (t1393/ST5) was identified in nine neonates; microarray analysis and PCR revealed that it contained the ETA encoding gene. Screening of staff, mothers and healthy neonates and environmental cultures did not reveal the presence of the epidemic strain. However, the father of an infected neonate was found to be a carrier of MSSA t1393 five months after the outbreak started., Conclusion: Implementation of hygiene procedures and sanitization of the ward twice terminated the outbreak. Timely surveillance of infections, supported by molecular typing, is fundamental to prevent similar episodes among neonates.

Objective: To determine skin changes in patients of End Stage Renal Disease (ESRD) on maintenance hemodialysis (MHD) and factors affecting these changes., Study Design: Cross-sectional observational study., Place and Duration of Study: Nephrology Department, Mayo Hospital, Lahore in collaboration with Dermatology Department, King Edward Medical University, Lahore, from October 2015 to January 2016., Methodology: Two hundred patients who were undergoing MHD for more than three months were included in the study. Patients' demographic data, laboratory reports and dialysis records were noted in a predesigned questionnaire. Skin examination was carried out by consultant dermatologist after patient's permission., Results: Among 200 patients included in study, 105 were malesand rest of them were females. Major causes of ESRD were Diabetes Mellitus (n=83, 41.5%, followed by Hypertension (n=80, 40%), Nephrolithiasis (n=15, 7.5%) and Chronic glomerulonephritis (n=5, 2.5%). At least one cutaneous finding was present in every patient. Common skin findings observed were pigmentation (86%), xerosis (83%), pallor (79%), pruritus (69%), acquired ichthyosis (50.5%), and bacterial skin infections (18.5%). Among them, nail manifestations were half-and-half nails (52%), onychomycosis (30.5%), onycholysis (20.5%), subungual hyperkeratosis (23.5%), and Mee's lines (7.5). Among hair changes were sparse scalp hair (38.5%), brittle and lustreless hair (28%). The factors contributing to skin changes were patient's age, cause of ESRD, anti HCV positivity, high urea and creatinine levels, duration and frequency of hemodialysis, hemoglobin levels, calcium phosphate product and socioeconomic status. Some skin manifestations were interrelated with each other like xerosis with pruritus (p<0.001), pruritus with bacterial infection (p<0.022), acquired Ichthyosis (p=0.008) and hair changes (p=0.035)., Conclusion: ESRD patients on hemodialysis develop various skin changes during the course of disease process, which contribute to increased morbidity. Different factors affecting skin changes were the cause of ESRD, adequacy and duration of dialysis, employment, financial status, anti HCV positivity, and metabolic factors.

Background: Atopic dermatitis (AD) is associated with barrier disruption, immune dysregulation, and immunosuppressing treatments that can increase the association with an unusual number of infections., Objective: To determine whether adults with AD have an unusually large number of serious infections and related outcomes., Methods: Data from the 2002 to 2012 National Inpatient Sample were analyzed, including an approximately 20% sample of all US hospitalizations (n = 72,108,077 adults). Prevalence of serious infections in hospitalized patients with vs without AD, length of stay, cost of care, and inpatient mortality secondary to serious infections were determined., Results: The prevalence of serious infections expressed as a percentage (95% confidence interval) was higher in adults hospitalized with than in those without AD (42.1% [41.6-42.6] vs 25.4% [25.2-25.6]; P = .0002). In logistic regression models with multiple predictors (multivariable logistic regression models), AD was associated with 32 of 38 infections examined. Associated cutaneous infections included eczema herpeticum (odds ratio [95% confidence interval] adjusted for other predictors: 67.93 [47.93-96.28]), erysipelas (11.15 [9.47-13.1]), and cellulitis (4.53 [4.42-4.64]). Associated respiratory infections included aspergillosis (1.51 [1.21-1.88]) and tuberculosis (1.57 [1.41-1.76]). AD was associated with extracutaneous, multiorgan, and systemic infections, including infectious arthropathy (2.01 [1.84-2.20]), endocarditis (1.25 [1.12-1.39]), encephalitis (1.65 [1.40-1.96]), and methicillin-resistant Staphylococcus aureus infections (3.29 [3.17-3.42]). Patients with AD hospitalized with vs without any serious infection had an increased geometric mean cost of inpatient care ($8,273 [8,126-8,423] vs $7,179 [7,052-7,307]) and length of stay (5.3 days [5.2-5.3] vs 3.9 [3.9-4.0]; P = .0002), with $11 to $228 million excess annual costs from hospitalization with serious infections in adults with AD., Conclusion: Adults with AD had increased cutaneous, respiratory, multiorgan, and systemic infections, which were associated with a considerable cost burden., (Copyright © 2017 American College of Allergy, Asthma & Immunology.

Background: Atopic dermatitis (AD) is characterized by skin barrier defects, T helper type 2 cell activation, and increased risk for cutaneous and extracutaneous infections. In clinical trials, dupilumab appeared to decrease rates of skin infections in AD., Objective: We aimed to determine the impact of dupilumab on rates of skin and other infections in patients with moderate-to-severe AD., Methods: We conducted a systematic review and meta-analysis of randomized controlled trials of dupilumab for AD. We searched the PubMed database for relevant studies. Risk ratios (RRs) and 95% confidence intervals (CIs) for skin infections, herpesvirus infections, and overall infections and infestations were calculated for dupilumab compared with for placebo by using binary random effects meta-analysis. For the analysis of eczema herpeticum, Peto odds ratios were calculated., Results: Eight randomized controlled trials in 4 publications with 2706 participants were included, with follow-up time ranging from 4 to 52 weeks. Meta-analysis including all dosing schedules and follow-up times showed a RR of skin infection of 0.54 (95% CI, 0.42-0.70) and an odds ratio of eczema herpeticum of 0.34 (95% CI, 0.14-0.84) for dupilumab compared with placebo. No significant association was found for dupilumab with overall herpesvirus infections (RR, 1.16; 95% CI, 0.78-1.74) and overall infections (RR, 0.98; 95% CI, 0.83-1.16)., Limitations: Our analysis is limited by the short follow-up time in most trials and the relatively low number of patients treated with dupilumab to date., Conclusions: Dupilumab is associated with a decreased incidence of skin infections and eczema herpeticum in adults with moderate-to-severe AD. The mechanism underlying this association is uncertain but is likely related to improvement in AD severity. Dupilumab, a monoclonal antibody targeting interleukin 4 and interleukin 13, appears to significantly decrease the risk for skin infections and eczema herpeticum in adults with moderate-to-severe AD., (Copyright © 2017 American Academy of Dermatology, Inc.

The objective of this study was to describe the occurrence of skin infection associated hospitalizations in children born in Western Australia (WA). We conducted a retrospective cohort study of all children born in WA between 1996 and 2012 (n = 469,589). Of these, 31,348 (6.7%) were Aboriginal and 240,237 (51.2%) were boys. We report the annual age-specific hospital admission rates by geographical location and diagnostic category. We applied log-linear regression modelling to analyse changes in temporal trends of hospitalizations. Hospitalization rates for skin infections in Aboriginal children (31.7/1000 child-years; 95% confidence interval [CI] 31.0-32.4) were 15.0 times higher (95% CI 14.5-15.5; P<0.001) than those of non-Aboriginal children (2.1/1000 child-years; 95% CI 2.0-2.1). Most admissions in Aboriginal children were due to abscess, cellulitis and scabies (84.3%), while impetigo and pyoderma were the predominant causes in non-Aboriginal children (97.7%). Admissions declined with age, with the highest rates for all skin infections observed in infants. Admissions increased with remoteness. Multiple admissions were more common in Aboriginal children. Excess admissions in Aboriginal children were observed during the wet season in the Kimberley and during summer in metropolitan areas. Our study findings show that skin infections are a significant cause of severe disease, requiring hospitalization in Western Australian children, with Aboriginal children at a particularly high risk. Improved community-level prevention of skin infections and the provision of effective primary care are crucial in reducing the burden of skin infection associated hospitalizations. The contribution of sociodemographic and environmental risk factors warrant further investigation.

Background: The impact of dermatology consultation on the care of children with oncologic conditions is unknown., Objective: To review outpatient dermatology visits and the resulting impact on diagnosis and management of pediatric oncology patients., Method: Retrospective review of pediatric oncology patients with outpatient dermatology visits at a tertiary care center from 2008 to 2015., Results: The most common dermatologic diagnoses in 516 patients were skin infections (21.3%) and nonmalignant skin eruptions (33.4%). A diagnosis of significant impact (ie, malignancy, adverse cutaneous drug reaction, graft-versus-host disease, varicella-zoster virus, or herpes simplex virus infection), was made at the dermatology clinic in 14.7% of visits. Consultation resulted in a change in diagnosis in 59.8% of patients, change in dermatologic management in 72.4% of patients, and change in management of noncutaneous issues in 12.4% of patients., Limitations: The use of electronic medical records, the nongeneralizable study population, and the retrospective design represent potential limitations., Conclusion: Outpatient dermatology consultation can affect the care of pediatric oncology patients with respect to diagnosis and treatment of skin conditions and management of nondermatologic issues., (Copyright © 2017 American Academy of Dermatology, Inc.

Background: Skin infections account for 40% of emergency visits in pediatric dermatology. It is important to promptly recognize skin infections with potential complications and initiate treatment. However some characteristic skin findings may imitate skin infections and are often misdiagnosed., Objectives: To illustrate frequent pediatric skin infections and pitfalls in view of imitators and differential diagnoses., Materials and Methods: A photo quiz is presented with the discussion of a selection of acute pediatric skin infections in comparison to their infectious or noninfectious differential diagnoses., Results: The following infectious skin conditions and imitators are described and clinical clues for differentiation highlighted: eczema herpeticum and bacterial superinfection of atopic dermatitis; exanthematous hand, foot and mouth disease and varicella infection; erythema chronicum multilocularis and anular urticaria; Gianotti-Crosti syndrome and Gianotti-Crosti-like reaction; bacterial folliculitis of the scalp and kerion celsi and eosinophilic pustular folliculitis of the scalp; cutaneous Leishmaniasis and idiopathic facial aseptic granuloma; allergic and bacterial lymphangitis; bullous impetigo contagiosa and nonaccidental scalding., Conclusions: Careful anamnesis and skin examination with attention to the here illustrated differential diagnoses are essential to avoid pitfalls in the evaluation of acute pediatric skin infections.

Study Objective: We examine adult emergency department (ED) admission rates for the top 15 most frequently admitted conditions, and assess the relative contribution in admission rate variation attributable to the provider and hospital., Methods: This was a retrospective, cross-sectional study of ED encounters (≥18years) from 19 EDs and 603 providers (January 2012-December 2013), linked to the Area Health Resources File for county-level information on healthcare resources. "Hospital admission" was the outcome, a composite of inpatient, observation, or intra-hospital transfer. We studied the 15 most commonly admitted conditions, and calculated condition-specific risk-standardized hospital admission rates (RSARs) using multi-level hierarchical generalized linear models. We then decomposed the relative contribution of provider-level and hospital-level variation for each condition., Results: The top 15 conditions made up 34% of encounters and 49% of admissions. After adjustment, the eight conditions with the highest hospital-level variation were: 1) injuries, 2) extremity fracture (except hip fracture), 3) skin infection, 4) lower respiratory disease, 5) asthma/chronic obstructive pulmonary disease (A&C), 6) abdominal pain, 7) fluid/electrolyte disorders, and 8) chest pain. Hospital-level intra-class correlation coefficients (ICC) ranged from 0.042 for A&C to 0.167 for extremity fractures. Provider-level ICCs ranged from 0.026 for abdominal pain to 0.104 for chest pain. Several patient, hospital, and community factors were associated with admission rates, but these varied across conditions., Conclusion: For different conditions, there were different contributions to variation at the hospital- and provider-level. These findings deserve consideration when designing interventions to optimize admission decisions and in value-based payment programs., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: Improvement of quality of life in old age and prevention of age-associated diseases have become the main focus of research into aging; however, information regarding the skin health status of geriatric patients still remains sparse., Goal: To investigate the extent of dermatological diseases in hospitalized geriatric patients, map the most prevalent ones, check for any gender differences and document any correlations with duration of hospitalization and results of geriatric assessments., Patients and Methods: A total of 110 hospitalized geriatric patients underwent a complete dermatological examination at the Evangelical Geriatric Hospital (Evangelisches Geriatriezentrum) Berlin. The collected information was stratified according to dermatological diagnosis, results of geriatric assessments, duration of hospitalization, age and gender of the patients., Results: The average number of diagnosed skin diseases per patient was 3.7 ± 1.8 for the female population and 4.3 ± 2.0 for the male population. After categorizing all diagnosed skin diseases, infectious diseases were found to be most common in both female and male patients (55 % and 58 %, respectively) followed by vascular diseases (46.7 % and 54 %, respectively). Precancerous skin lesions and epithelial skin cancer were more frequent in men than in women (20 % vs. 6.7 %, p < 0.037 and 34 % vs. 13.3 %, p < 0.010, respectively). Pruritus showed a positive correlation with the duration of hospitalization and a negative correlation with the Barthel index and Tinetti score on the day of discharge, indicating that pruritus may have a significant impact on the physical condition of elderly multimorbid patients and on the static and dynamic balance abilities., Conclusion: Our results demonstrate that skin health in the elderly is compromised and disregarded and this should constitute one of the top priorities of healthcare specialists and physicians in the future.

Background: Current guidelines recommend blood cultures in skin and soft-tissue infection (SSTI) patients only with signs of systemic toxicity and wound cultures for severe purulent infections. Our objectives were to determine: 1) blood and wound culture yields in patients admitted with SSTIs; 2) whether injection drug users (IDUs) and febrile patients had higher blood culture yields; and 3) whether blood and wound cultures grew organisms sensitive to typical SSTI empiric antibiotics., Methods: We prospectively enrolled adult patients admitted from the ED with SSTIs at an urban hospital. We recorded patient characteristics, including IDU, comorbidities and temperatures, and followed admitted patients throughout their hospital course., Results: Of 734 SSTI patients enrolled, 246 (33.5%) were admitted. Of 86 (35.0%) patients who had blood cultures, six had positive cultures (yield=7.0%; 95% confidence intervals [CIs] 3.2-14.4); 4 were methicillin sensitive Staphylococcus aureus (MSSA) and 2 were methicillin resistant (MRSA). Of 29 febrile patients, 1 had a positive culture (yield=3.5%; 95% CI 0.6-17.2). Of 101 admitted IDU patients, 46 (46%) received blood cultures, and 4 had positive cultures (yield=8.7%; 95% CI 3.4-20.3). Of 89 patients with purulent wounds, 44 (49.4%) patients had ED wound cultures. Thirteen had positive cultures (yield=29.6%; 95% CI 18.2-44.2%). Most were MRSA, MSSA, and group A Streptococcus species - all sensitive to Vancomycin., Conclusions: Febrile and IDU patients had low yields of blood cultures similar to yields in non-IDU and afebrile patients. All blood and wound culture species were adequately covered by currently recommended empiric antibiotic regimens., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Purpose of Review: Skin and soft tissue infections are frequent contributors to morbidity and mortality in the immunocompromised host. This article reviews the changing epidemiology and clinical manifestations of the most common cutaneous pathogens in non-HIV immunocompromised hosts, including patients with solid organ transplants, stem cell transplants, solid tumors, hematologic malignancies, and receiving chronic immunosuppressive therapy for inflammatory disorders., Recent Findings: Defects in the innate or adaptive immune response can predispose the immunocompromised host to certain cutaneous infections in a predictive fashion. Cutaneous lesions in patients with neutrophil defects are commonly due to bacteria, Candida, or invasive molds. Skin lesions in patients with cellular or humoral immunodeficiencies can be due to encapsulated bacteria, Nocardia, mycobacteria, endemic fungal infections, herpesviruses, or parasites. Skin lesions may reflect primary inoculation or, more commonly, disseminated infection. Tissue samples for microscopy, culture, and histopathology are critical to making an accurate diagnosis given the nonspecific and heterogeneous appearance of these skin lesions due to a blunted immune response., Summary: As the population of non-HIV immunosuppressed hosts expands with advances in medical therapies, the frequency and variety of cutaneous diseases in these hosts will increase.

Background: Numerous risk factors place palliative care patients at an increased risk of skin infections, dermatitis, and pressure sores. Furthermore, worsening of chronic skin disorders can be expected, as well as the development of treatment-induced and malignancy-related dermatoses. The objective of the present study was to investigate the prevalence and treatment of dermatological conditions in patients receiving hospital-based palliative care., Methods: Two hundred seventy-one palliative patients were enrolled. All assessments were conducted by dermatologists. Skin lesions were classified into seven categories: infections, skin tumors, dermatitis, chronic wounds, nail and hair disorders, pruritus, and other unclassified conditions. Treatment modalities were classified as topical only or systemic., Results: Overall, 1,267 dermatological conditions were recorded, 49 % of which were hospital-acquired. All patients had at least one dermatological condition, and more than 50 different dermatological disorders were noted. The most common group of skin disorders was dermatitis (18.3 % of all dermatological conditions), followed by nail and hair disorders (17.5 %). Almost 16 % of dermatological conditions were treated systemically., Conclusions: Dermatological conditions are a common and clinically significant problem for palliative patients. The inclusion of dermatologists in multidisciplinary palliative teams should prove helpful in the management of these patients., (© 2017 Deutsche Dermatologische Gesellschaft (DDG).

Introduction: The incidence of the human papilloma virus (HPV) has not dropped in HIV-positive patients despite the discovery of antiretroviral therapy (ART). Our goal is to assess the prevalence of HPV in HIV patients and its relationship with the epidemiological and virological characteristics of HIV patients., Patients and Methods: Retrospective cohort of 965 patients diagnosed with HIV from 1998 to 2012. We analyzed patients' demographic factors and factors related to the HPV., Results: Of the 965 patients examined, 333 consulted a dermatologist. Of these, 52 patients had genital warts (15.6%), 43 had common warts (12.9%) and 8% had both conditions. In total, 28.5% of patients had a skin lesion caused by HPV., Discussion and Conclusion: This is the first longitudinal observational study carried out on HIV-positive patients in the era of ART in which HPV infection is the most common skin pathology. We observed a similar trend in countries with access to ART. This study spreads awareness on the importance of preventing HPV and the difficulty of treating it in HIV-positive patients., (Copyright © 2017 Elsevier España, S.L.U. All rights reserved.)

Objective: The purpose of this study was to determine the incidence of infectious complications after ultrasound-guided breast interventions performed with an intermediate-level disinfection protocol without an ultrasound probe cover., Materials and Methods: Two independent institutional databases were searched to identify breast infections in patients who underwent ultrasound-guided interventions between January 2005 and July 2013. The departments of radiology and infectious diseases independently maintained these databases. A comprehensive retrospective chart review based on periprocedural antibiotic use and clinical documentation of infection was also performed to reduce the likelihood of missing potential infectious complications., Results: A total of 12,708 ultrasound-guided breast procedures were performed in the time frame of this study. All potential cases of procedure-related infection were included for subspecialist review in an effort to give the most conservative (highest) estimate of infectious complications. Among these cases, 14 documented cases of possible procedure-related infection were identified, for an overall incidence of 0.11%. All infections were localized skin or soft-tissue infections and adequately treated with a short course of oral antibiotics. No cases of more serious infections or sepsis were found. None of the reported infections required IV antibiotic therapy, percutaneous intervention, surgical intervention, or hospitalization., Conclusion: The incidence of infectious complications after an ultrasound-guided breast intervention without an ultrasound probe cover is extremely low. Physicians can use this information in the development of their disinfection protocols and to provide accurate information in counseling patients during preprocedural consultation.

Introduction: Although dermatologic conditions bring relatively few people to the Emergency Department, hospitalized patients, especially older people, often suffer from skin problems that contribute to their morbidity., Aims: We wanted to identify the frequency, clinical course, treatment and influence on hospitalization of dermatologic conditions in patients hospitalized in internal and geriatric departments in Galilee Medical Center. We concentrated on two groups of adults, aged 40-65 years (adult group) and above 65 years (elderly group), in order to understand differences in the cause of referral, type of diagnosis and mode of treatment., Methods: We performed a retrospective review of 82 hospitalized patients who were referred for dermatological consultation between May-September 2013. Of the 82 patients, 47.6% made up the 'adult' group and 52.4% the 'elderly' group; 62.2% of patients were independent, 18.3% partially independent and 19.5% needed nursing care., Results: Skin infections (38.3%), allergy (mostly drug induced) (23.5%) and trophic disorders (18.5%) were the most common diagnoses. 'Elderly' were less often referred to dermatological consultation than 'adults' (44.3% vs. 55.7%, respectively); skin infections were more common in the 'elderly' (44.8% vs. 55.7%). Nursing care patients (19.5%) were least referred to dermatological consultation, but severity of skin condition (the number of diagnoses and number of treatments per patient) was greater in nursing care patients., Conclusions: The clinical course between the independent and nursing care patients varies in the number of requests, the different type of diagnoses, the severity of the conditions and the number of treatments provided., Discussion: Our study emphasizes the importance of skin examination by a dermatologist, considering the high number of referrals for dermatological consultations. On the other hand, there was a significant difference between the 'elderly' and 'adult' groups, with fewer referrals for dermatological consultations by the medical staff in the 'elderly' group. Our results resemble those in the literature, having identified the most common skin problems in two groups of hospitalized patients.

Purpose of Review: Skin and soft tissue infections (SSTIs) are the most frequent infectious cause of referrals to emergency departments and hospital admissions in developed world, contributing to significant morbidity and healthcare expenditures. We sought to review recent literature covering epidemiology and management of SSTIs., Recent Findings: Incidence trends of SSTIs were increasing worldwide with Staphylococcus aureus and streptococci predominating and methicillin-resistant S. aureus (MRSA) posing additional challenges, because of high rates of treatment failure and relapse. Development of new antimicrobials was associated with an appraisal of regulatory definitions and endpoints. Prediction of clinical response can be very tricky, because of variable risk factors for recurrence or treatment failure, depending mostly on the host. Precise indications for new antimicrobials should be established; their integration into clinical practice algorithms may serve reduction of unnecessary admissions, overtreatment and total costs., Summary: New antimicrobials with activity against MRSA have been recently launched. Long-acting agents, mainly oritavancin and dalbavancin, provide the opportunity of single-dose treatment and early discharge. Further outpatient treatment options include new per os antibiotics such as oxazolidinones. Validated assessment tools are urgently needed to support decision-making toward rational resource utilization and delivery of optimal treatment.
